Description

TECHNOLOGY AREA

The utility model relates to image creation technology or printer technology, particularly a chip and an associated printing consumable.

BACKGROUND

In the prior art, for some existing printing consumables such as certain types (e.g. color cartridges), it is necessary to achieve the exact positioning in the plumb direction or mounting direction with the help of a clamping handle or other aids. However, this can result in some offsets in the width direction of the fully assembled printing consumables (e.g. color cartridges), because a specific width allowance has already been set for the installation position of each printing consumable. In the case of such printing consumables (e.g. color cartridges), the chips are electrically connected components and are usually equipped with terminals of smaller width dimensions. Even a slight offset in the width direction of a printing consumable can affect the electrical connection between the terminal and the printer, and therefore the printing consumable cannot function properly.

Therefore, although the printer-side contact pin block is able to prevent displacement of the printing consumable in its width direction thanks to the actual elastic deformations of the contact pins and the chip, this restraining effect may be difficult to achieve when the printing consumable chips with 7 or 9 contacts are flatbed -Chips with 5 contacts are escalated, so that the contacts on the escalated chips have apparently decreased in number and are not yet very evenly designed, despite the substantially constant profiles and sizes of the substrates.

DESCRIPTION OF THE USE MODEL

Based on the shortcomings of the conventional embodiments, a practical utility model is provided which can expediently prevent displacement of the printing consumable in its width direction in its own installation position by fitting the chip with the contact pin block.

Unless otherwise specified or restricted, the number term “multiple” indicates two or more than two as the number of items. The terms such as “installation”, “connection”, “connection” and “fixing” should be understood in general terms, for example a connection can be a fixed connection, detachable connection, integrated connection, direct or indirect connection. The industry professionals can understand the inventive meanings of the above terms depending on the situation.

The terms used in the description of the embodiments according to the invention such as “top” or “bottom” depend on the schematic representations in the figures and do not represent a limitation of the embodiment according to the invention. In this context, it is understandable that an element that is supposedly “on ” or “under” another element, so it can be attached not only directly, but also indirectly via an intermediate element “on” or “under” this other element.

In the prior art, the substrate has, as a main component of the chip, a memory unit, terminals, an electronic component, and a circuit board that electrically connects the terminals and the electronic component to the memory unit. The memory is useful for storing manufacturer, ink quantity, cartridge body category and ink color data. The electronic component works with the memory unit to implement the chip's internal processes to make the chip function properly. If the color cartridge is already successfully inserted in the predetermined mounting zone in the printer, the actions such as data transfers, acknowledgments and data exchanges between the memory and the printer are ready, which actions will be based on the couplings of the terminals to the printer-side contact pins.

How out 1 As can be seen as a view of a color cartridge 10 to be mounted in the cartridge mounting zone 90, the printing consumable appears to be a frequently changed component for a printer (printing device), the chip 20 being one of the components of the printing consumable. A printing consumable can be a consumable cartridge, color cartridge or selenium drum and ribbon. The chip 20 then appears as a component of the consumable cartridge, color cartridge or the selenium drum or ink ribbon.

In relation to 1 Color cartridge is taken as an example of the printing consumable to be used. In this case, the following description refers to color cartridge as an example of the printing consumable to be used.

How out 1 As can be seen, the cartridge mounting zone 90 serves as a member in the printer for receiving one or more color cartridges 10, the color cartridge 10 being mounted in the cartridge mounting zone 90 along a mounting direction P. A used-up color cartridge 10 can be replaced with a new color cartridge. The color cartridge 10 includes a chip 20, a clamping handle 30, an ink outlet 40 and a cartridge body 50, while the cartridge mounting zone 90 is provided with a contact pin block 91, an ink supply 92, an opening 95 and a bottom wall 90a. The ink cartridge 10 is then inserted into the cartridge mounting zone 90 from the opening 95 along the mounting direction P. Printer inks are stored in the cartridge body 50 and reach the print head through the ink outlet 40 and the ink supply 92 to carry out printing. The chip 20 is provided with a set of terminals which can be electrically connected to the contact pins 91a in the contact pin block 91 to effect signal transmission. The ink cartridge 10 is fixed in the cartridge mounting zone 90 with the clamping handle 30 in order to prevent possible detachment of the ink cartridge 10 from the cartridge mounting zone 90.

A three-dimensional rectangular coordinate system is defined, namely an X, Y, and Z axis system, so that the ink cartridge 10 coincides with the cartridge mounting zone 90 with respect to the three-dimensional rectangular coordinate system. Assuming that the mounting direction P of the ink cartridge 10 in the cartridge mounting zone 90 is defined as a -Z axis, the release direction of the ink cartridge 10 emanating from the cartridge mounting zone 90 is then considered a +Z axis, so the opening 95 lies in the +Z -axis and the bottom wall 90a in the -Z-axis, while the Y-direction presents itself as a width direction of the ink cartridge. Normally, the printer is placed on a desktop or printer desktop so that the opening 95 of the cartridge mounting zone 90 is above the direction of gravity, and the bottom wall 90a is below the direction of gravity is located to facilitate assembly or removal of the color cartridge 10. The cartridge mounting zone 90 may accommodate one or more color cartridges 10 and may include one or more mounting positions. Four cartridges can hold four different ink colors, e.g. B. black, yellow, blue and red.

Specifically, the cartridge mounting zone 90 can be designed as an approximately rectangle or square with an opening 95, the inner wall and bottom wall 90a of which together form an installation position. The contact pin block 91 is attached to the first side wall 90c of the cartridge mounting zone 90 while four installation positions are sequentially laid out along the Y axis. The direction perpendicular to the Y-axis and Z-axis is represented as the X-axis, while the direction pointing from the inside of the cartridge mounting zone 90 onto the contact pin block 91 is considered the +X-axis. The +X axis remains perpendicular to the first side wall 90c, so that the +Y axis is to the left when looking into the +X axis provided the +Z axis is at the top of the YZ plane.

In 2 the contact pin block 91 is shown. How out 2 As can be seen, the contact pin block 91 comprises a base 910 and a plurality of contact pins attached to the base 910, namely a first contact pin 911, a second contact pin 912, a third contact pin 913, a fourth contact pin 914 and a fifth contact pin 915. The contact pin is a thin sheet of metal that is electrically conductive and not susceptible to wear. The base 910 has several narrow gaps, namely a first narrow gap 981, a second narrow gap 982, a third narrow gap 983, a fourth narrow gap 984 and a fifth narrow gap 985. Each narrow gap is complementary to a corresponding contact pin and is also U-shaped a narrow slot in the +Z axis, so that several contact pins can be inserted along the -Z axis through the narrow slot into the narrow gap. Specifically, the first contact pin 911 is inserted along the -Z axis through the narrow slot in the first narrow gap 981. The assembly process from the second contact pin 912 to the fifth contact pin 915 looks the same as this and is therefore not detailed here.

During operation of the printer, one side of each contact pin is connected to the primary circuit of the inkjet printer via the internal circuitry of the cartridge mounting zone 90, while the other side is coupled to the chip 20. The arrangements from the first contact pin 911 to the fifth contact pin 915 are identical (see 3 ). The first contact pin 911 is taken as an example, which has a first segment 911a, a second segment 911b and a third segment 911c. The first segment 911a is connected to the chip 20, while the second segment 911b is connected to the internal circuitry of the inkjet printer, with the third segment 911c connected to the first segment 911a and the second segment 911b.

The third segment 911c lies in the +Z axis of the first contact pin 911. The first contact pin 911 is fixed in the first narrow gap 981 via the third segment 911c or a part of the third segment 911c (for example the horizontal segment 911h of the third segment 911c). . The first segment 911a and the second segment 911b are arranged at one end of the -Z axis of the first contact pin 911 so that the first segment 911a and the second segment 911b can deform elastically and can also reset easily afterwards. The first segment 911a of the first contact pin 911 is designed in the -X axis, while the second segment 911b extends in the +X axis.

Except for the third segment 911c, the first segment 911a and the second segment 911b each protrude from the base 910. Specifically, the first segment 911a and the second segment 911b protrude in the X axis from the base 910, with the base 910 lying between the first segment 911a and the second segment 911b. Compared with the second segment 911b, the first segment 911a is closer to the installation position. The third segment 911c includes a first vertical segment 911k that remains perpendicular to the X-axis, as well as a second vertical segment 911j and a horizontal segment 911h that remains parallel to the vertical segments 911j is connected. The first vertical segment 911k and the second vertical segment 911j each extend parallel to the mounting direction of the ink cartridge in the cartridge mounting zone (namely: Z axis). Compared to the second vertical segment 911j, the first vertical segment 911k is located closer to the installation position, with one end of the first vertical segment 911k connected to the first segment 911a, and one end of the second vertical segment 911j connected to the second segment 911b. The horizontal segment 911h or the first vertical segment 911k and the second vertical segment 911j are fixed along the +Z axis in the first narrow gap 981. The first segment 911a is located at one end of the first contact pin 911. The first contact pin 911 is electrically connected to the chip 20 via the first segment 911a, whereby a contact area is formed. In addition, the second segment 911b is electrically connected to the internal circuit of the inkjet printer. The first segment 911a has a first surface area 911a1, a second surface area 911a2, a third surface area 911a3 and a fourth surface area 911a4, the third surface area 911a3 lying along the Y direction opposite the fourth surface area 911a4, while the encirclement of the first Surface area 911a1 forms a ridge with the second surface area 911a2. The first vertical segment 911k means a vertical area, and the second segment 911b means a different mountain ridge, and the second vertical segment 911j means a different vertical area. The second contact pin 912 to the fifth contact pin 915 are designed and arranged in the same way as the first contact pin 911 and are therefore no longer illustrated and described here.

How out 1 and 4 As can be seen, the chip 20 inserted in the color cartridge 10 comprises a substrate 21a, in whose outer plane 22d facing away from the cartridge body 50 five terminals 23e are installed.

The first terminal 231, the second terminal 232, the third terminal 233 and the fourth terminal 234 are located on the -Y side of the external connection surface, while the fifth terminal 235 is on the +Y side of the external connection surface. In addition, the contact zone of the second terminal, the third terminal and the fifth terminal lie in a straight line L1 parallel to the Y-axis, while the contact zone of the first terminal and the fourth terminal lie in a straight line L2 parallel to the Y-axis, where the straight line L2 is on the +Z side of the straight line L1. In the accompanying drawings, the hatched areas in the centers of the terminals act to indicate the contact zone of the corresponding terminal.

The first terminal 231 to the fifth terminal 235 are all installed in the outer plane 22d, with the distances between the single end face and the outer plane 22d of the five terminals being equal, so that the contact zones from the first terminal 231 to the fifth terminal 235 lie in an identical plane. Furthermore, the five terminals are approximate in size and are considerably larger in Z-axis lengths than Y-axis lengths. A possible slight displacement of the ink cartridge 10 in the Y direction can affect the electrical connection of the terminals to the printer, which is why the ink cartridge 10 cannot function. The first clamp 231 to the fourth clamp 234 are all inserted in the -Y side of the outer plane 22d and are more closely positioned in position, while the fifth clamp 235 is inserted in the +Y side of the outer plane 22d and also from the first clamp 231 to the fourth terminal 234 is further turned away. In the fully assembled state, the contact pins in contact with the chip 20 are each deformed somewhat elastically, so that a static friction force is available against the displacement of the color cartridge 10 in the Y direction when the entire color cartridge 10 tends to be displaced in the Y direction. However, there are only five contact pins (i.e. the first contact pin 911 to the fifth contact pin 915), and all of the contact zones from the first terminal 231 to the fifth terminal 235 are in an identical plane. In this case, the deformation dimensions of the five contact pins are essentially the same and can provide low static friction forces. In addition, the existing terminals are too few and extremely inconsistent. As a result, the displacement of the chip 20 or the color cartridge 10 in the Y direction in the installed position cannot be effectively prevented.

With reference to a first embodiment

• Wie aus 5 bis 11 ersichtlich, umfasst die Farbkartusche 400 einen Kartuschenkörper 410 und einen Chip 300, wobei der Kartuschenkörper 410 mit einer mit dem Chip 300 komplementären Aufnahmestelle 411 ausgebildet ist, während der Chip 300 ein Substrat 310 umfasst, dessen die größte Fläche belegende Oberfläche als eine Vorderfläche 310a definiert ist, in der wenigstens eine an die Kontaktstifte drückende Außenklemme 320 installiert ist. Zudem ist die zu der Vorderfläche 310a parallele Fläche des Substrates 310 ist als eine Rückfläche 310b definiert, in der wenigstens eine nicht an jeglichen Kontaktstift drückende Innenklemme 330 installiert ist. Die Farbkartusche 400 und/oder der Chip 300 umfasst noch eine zweite Komponente (ausgebildet als ein Leitelement 500 in der vorliegenden Ausführungsform, in einigen anderen Ausführungsformen jedoch möglich als ein Chiphalter), welche die druckerseitigen Kontaktstifte mit der Innenklemme 330 elektrisch verbindet. Das Leitelement 500 ist zwischen der Aufnahmestelle 411 und dem Substrat 310 eingesetzt und umfasst zudem einen an die Innenklemme 330 drückenden Anschlussteil 510 und eine mit druckerseitigen entsprechenden Kontaktstiften zusammenpassende Außenkontaktzone 520. Das Leitelement 500 ist mit einem nicht mit dem Substrat 310 überlappbaren Epitaxieteil 530 versehen, wobei die Außenkontaktzone 520 an einer auf die Rückfläche 310b zeigenden Seite des Epitaxieteils 530 liegt. Das Leitelement 500 ist mit dem Chip 300 elektrisch verbunden, weshalb sich das Leitelement 500 als ein Anbauteil des Chips 300 ansehen lässt. Zudem lässt sich das Leitelement 500 auch als ein Anbauteil des Kartuschenkörpers 410 ansehen, beispielsweise als ein Chiphalter zwischen der Aufnahmestelle 411 und dem Substrat 310 einsetzen, um wenigstens einen Teil des Chips 300 zu fixieren oder anzudrücken.

A first embodiment is described in detail below, whereby the above-mentioned fit of the chip with the contact pin block 91 applies to all other embodiments and the functionalities of the individual terminals correspond to the mentioned first terminal 231 to the fifth terminal 235:

• How out 5 until 11 As can be seen, the color cartridge 400 comprises a cartridge body 410 and a chip 300, the cartridge body 410 being formed with a receiving point 411 complementary to the chip 300, while the chip 300 comprises a substrate 310, the surface of which covers the largest area defined as a front surface 310a is, in which at least one external terminal 320 pressing on the contact pins is installed. In addition, the surface of the substrate 310 parallel to the front surface 310a is defined as a rear surface 310b, in which at least one inner terminal 330 that does not press against any contact pin is installed. The color cartridge 400 and/or the chip 300 also includes a second component (formed as a conductive element 500 in the present embodiment, but possible as a chip holder in some other embodiments), which electrically connects the printer-side contact pins to the inner terminal 330. The guide element 500 is inserted between the receiving point 411 and the substrate 310 and also includes a connecting part 510 that presses against the inner clamp 330 and a connection part on the printer side corresponding contact pins matching external contact zone 520. The guide element 500 is provided with an epitaxial part 530 that cannot be overlapped with the substrate 310, the external contact zone 520 lying on a side of the epitaxial part 530 pointing towards the rear surface 310b. The conductive element 500 is electrically connected to the chip 300, which is why the conductive element 500 can be viewed as an add-on part of the chip 300. In addition, the guide element 500 can also be viewed as an attachment to the cartridge body 410, for example as a chip holder between the receiving point 411 and the substrate 310 in order to fix or press on at least part of the chip 300.

In the present embodiment, the inner clamp 330 is installed in the back surface 310b, with the guide member 500 being welded to the back surface 310b such that at least a portion of the guide member 500 is located on the -X axis side of the back surface 310b. It is understandable that in other embodiments the inner clamp 330 can be installed in the front surface 310a, with the guide element 500 being welded to the front surface 310a, so that at least a portion of the guide element 500 is located on the +X axis of the front surface. Since the external contact zone 520 lies outside the guide element 500 and, in addition, there is a certain surface deviation between the external contact zone and the external terminal 320, any displacement of the ink cartridge 400 or the chip 300 in the width direction (Y direction) relative to the contact pins in the external contact zone 520 can occur corresponding optimization of the profile and/or the size of the substrate 310 can be limited. In addition, according to the invention, a second component is provided which is provided with an epitaxial part that cannot be overlapped with the substrate. When the chip is in operation, the contact pins can press against the substrate and the epitaxial part. Thanks to the arrangement of the epitaxial part, the conductive surface for contacting the contact pins is enlarged and the functionality of the chip is largely maintained. Furthermore, the terminals may be spaced apart or insulated to provide short circuit resistance. In addition, an appropriate surface deviation can be arranged between the contact zone of the contact pin with the substrate and the contact zone of the contact pin with the epitaxial part in order to limit displacement of the printing consumable along its own width direction and thus to strengthen the connection robustness between the chip and the contact pin block. This can reduce the risk of short circuits between the terminals during chip operation. In addition, reliable, robust contacts are achieved by ensuring that the deformation levels or crushing forces of the individual contact pins remain different when the chip or printing consumable is fully assembled.

In this embodiment, the chip 300 further includes an electrical component 350 protruding in the rear surface 310b and a memory unit 340 electrically connected to the electrical component 350, the external terminal 320 and the internal terminal 330. Specifically, the guide element 500 can be attached either to the chip 300 (guide element 500 as an attachment of the chip 300) or to the cartridge body 410 (guide plate 500 as an attachment to the cartridge body 410) and also made of conventional conductive materials such as metal, conductive silicone , conductive plastic or conductive ceramic, provided that an electrical connection of the corresponding contact pins to the inner terminal 330 is achieved. In addition, the second component can be made of metal or conductive plastic, conductive silicone, conductive ceramic.

In the first embodiment of the invention with reference to 5 until 8th The guide plate 540 fixed in the chip 300 functions as a guide element 500, the substrate 310 being formed with a gap 311 passing between the front surface 310a and the rear surface 310b on the +Y side at the -Z end, the inner clamp 330 is attached to the edge of the gap 311. The part of the guide plate 540 that can be overlapped with the inner clamp 330 acts as a connecting part 510 and, moreover, the part located within the gap 311 acts as an epitaxial part 530, so that the external contact zone 520 is exposed from the gap 311 so that the individual contact pins can be inserted into the Reach into gap 311 and then press against external contact zone 520. In 7 the dashed lines mean the partial outlines of the gap 311 and the inner clamp 330. In 8th The dashed shaded area indicates the said connection part 510, in addition to which the area of the epitaxial part 530 in the guide plate 540 is illustrated. In the back surface 310b, an inner clamp 330 is reserved either on the -Y side at the +Z end or on the -Y side and +Z side. Accordingly, the profiling or the dimension of the guide element 500 is modified, for example the size of the guide element 500 is increased in order to enable better contact with the inner clamp 330, the length of the guide element 500 running along the Y axis being greater than half the length of the Substrate 310 is and the guide element 500 presses against the inner clamp 330 and is also provided with an epitaxial part 530. With such an arrangement, the guide element 500 is much more versatile in terms of dimensions larger and can then be more easily attached to the chip 300 or cartridge body 410.

In addition, the receiving point 411 is formed with a stop pin 414, while a stop part 312, which is complementary to the stop pin 414, is formed on one edge of the substrate and passes between the front surface 310a and the rear surface 310b. In the present embodiment, three stop parts 312 are formed on the edges on the +Z side and ±Y side of the substrate 310, accordingly the receiving point 411 includes three complementary stop pins 414.

In the present embodiment, the external clamps 320 include a first clamp 360 with a first contact zone 360a, a second clamp 370 with a second contact zone 370a, a third clamp 380 with a third contact zone 380a and a fourth clamp 390 with a fourth contact zone 390a, the Connecting line S2 between the first contact zone 360a and the fourth contact zone 390a runs parallel to the connecting line S1 between the second contact zone 370a and the third contact zone 380a. The connection lines S1 and S2 can each be viewed as a straight line in the front surface 310a because the individual external terminals 320 are made from a partial copper plating process. It may be further configured that the contact zone of each external terminal 320 and the external contact zone 520 are not in an identical straight line when projected onto the mounting direction of the printing consumable or chip relative to the printer.

• Die erste Klemme 131 (Datenklemme) dient zum Senden oder Empfangen von Daten/Signale und noch zum Detektieren eventuellen Kurzschlusses mindestens an einer Klemme unter der ersten Klemme 231, zweiten Klemme 232, dritten Klemme 233 und vierten Klemme 234.

The functionality of each individual terminal is defined as follows:

• The first terminal 131 (data terminal) is used to send or receive data/signals and to detect any short circuit at least on one terminal among the first terminal 231, second terminal 232, third terminal 233 and fourth terminal 234.

The second terminal 132 (clock terminal) is used to receive clock signals.

The third terminal 133 (power supply terminal) is used to include mains potential that deviates from ground potential (for example 3.6 V or 3.3 V) so that the storage unit (not shown) is supplied with a mains voltage.

The fourth terminal 134 (reset terminal) is used to reset the internal data of the wafer.

The epitaxial part 530 or the external contact zone 520 serves to include a ground potential.

In the present embodiment, the baffle 540 functions as the fifth clamp and adheres as a flat member to the back surface 310b so that there is a certain surface deviation between the external contact zone 520 and the front surface 310a. In the fully assembled state, the deformation amounts of the printer-side contact pins occurring along the projected from S1 in the front surface 310a.

The chip 300 has a left edge 310g, a right edge 310d, a surface 310e and a bottom surface 310f. The gap 311 is formed as a through groove in the Z axis, which not only passes between the front surface 310a and the back surface 310b, but also can be continuously connected to the surface 310e and the bottom surface 310f. Along the Z axis, the size of the guide element 500 is substantially approximated to the size of the substrate 310. With such an arrangement, the guide element 500 is much larger in size and can then be more easily attached to the chip 300 or the cartridge body 410.

When the conductive element 500 is attached to the chip 300 (conductive element 500 as an attachment of the chip 300), the conductive element 500 can be attached to the substrate 310 by means of a welding or conductive bonding method. The chip 300 is then attached to the receiving point 411 of the cartridge body 410.

When the guide element 500 is attached to the cartridge body 410 (guide plate 500 as an attachment of the cartridge body 410), the guide element 500 can be placed in the receiving point 411. The chip 300 is then attached to the receiving point 411 in such a way that at least one part is fixed or presses against the guide element 500. The gap 311 passes not only between the front surface 310a and the back surface 310b but also between the surface 310e and bottom surface 310f. This makes it much easier for the guide element 500 to be attached to the cartridge body 410 during the production process. The baffle 500 can be viewed as a flat plate with reference 7 or 8th , or as a component with a curved surface, or as a folded profile made of conductive material (for example sheet metal). The baffle 500 or the second component can be arranged firmly (as shown in 8th ) or attach elastically. The epitaxial part can deform or shift in the direction of the front surface 310a facing the back surface 310b. For example, a folded sheet with a hanging segment, or a lever shape with a suspended sheet end, or a curved metal sheet (as shown in 8 (e) and 8 (f) ) there is a certain gap 570 in the suspension zone when a contact pin touches the baffle 500 or the second component. In this case, the epitaxial part 530 or the external contact zone 520 can shift in the -X axis or in a direction of the front surface 310a pointing towards the rear surface 310b. In the case of the folded guide plate 500 with a suspension segment, or in the case of a lever shape with a suspended plate end, or in the case of the external contact zone 520 attached to the side of the suspension segment (as shown in 8 (a) and 8(b) ), the epitaxial part 530 or the external contact zone 520 can move in the -X axis or in a direction of the front surface 310a pointing towards the back surface 310b when a contact pin touches the baffle 500 or the second component. In the case of the baffle 500 curved from a metal sheet, the external contact zone 520 is formed at the apex of the curved section. The baffle 500 can still be attached elastically (as shown in 8(c) and 8 (d) ). Thus, the baffle 500 or the second component can partially deform (epitaxial part) in the -X axis or in a direction of the front surface 310a pointing towards the rear surface 310b and the epitaxial part 520 can move with the deformation of the baffle 500 or the second component, when a contact pin touches the baffle 500 or the second component. This configuration can dampen the force of the contact pins against the conductive element 500 and make the electrical connection of the conductive element 500 to the contact pins much more robust. The identification number 560 in the diagram refers to a rotating shaft.

The second component and the cartridge body 410 can be formed in one piece or as two separate components. With a one-piece combination of the second component with the cartridge body 410, the second component and the cartridge body 410 can be manufactured using a two-color injection molding process. For example, when producing the cartridge body 410 with a second component made of conductive plastic, one material container is filled with the conductive raw material and another material container is filled with general materials. The plasticization is then poured into an appropriate mold and shaped so that each injection molded part contains two different materials to meet the conductive specification of the second component. When making the second component from metal, the second component may first be prepared and then inserted into the mold, whereby the metal piece is non-removably inserted into the cartridge body 410 to meet the conductive specification of the second component. In a one-piece combination of the second component, the second component becomes part of the cartridge body 410, wherein both the second component and the cartridge body 410 are made of conductive material.

Since all the four outer terminals 320 are adjacent relative to the -Y side of the substrate 310 and the guide plate 540, on the other hand, is attached to the +Y side of the substrate 310, or is turned away from the four outer terminals 320, with between the outer contact zone 520 and If there is still a certain surface deviation in the contact zones of the external terminals 320, it is almost impossible for the droplet of printer inks or other conductive foreign bodies to establish an electrical connection between the external contact zone 520 and the contact zones of the external terminals 320. This means that the chip 300 in the fully assembled state does not remain vulnerable to possible short circuits due to external influences. In this regard, it is also conceivable that the guide plate 540 is attached to the -Y side of the substrate 310 and therefore replaces the first clamp and / or second clamp, with an inner clamp 330 in the rear surface 310b either on the -Y side on the + Z end or on -Y side and +Z side is reserved so that a notch is conveniently made in the substrate 310 next to the inner clamp 330 where a baffle is inserted to replace the first clamp.

If the color cartridge 400 is displaced in the -Y direction in the cartridge mounting zone 90, the further displacement is limited by the fact that the contact pins complementary to the external contact zone 520 press against the -Y side of the substrate 310 in the gap 311. In this regard, it is also conceivable that the gap 311 is designed as a through groove and therefore does not extend in the Y direction to the edge on the +Y side of the substrate 310, so that the displacement of the ink cartridge 400 into the +Y direction Direction can be limited by the interaction of the contact pins complementary to the external contact zone 520 with the substrate 310. Such a design can limit any displacements of the ink cartridge 400 or the chip 300 in its own width direction and increase the robustness of the connection between the
Improve color cartridge 400 or chip 300 with contact pin block 91. In addition, the individual terminals do not remain susceptible to short circuits during operation of the color cartridge 400 or the chip 300, because the external terminals 320 and the external contact zone are attached to the substrate and the baffle, respectively.

With reference to a second embodiment

In 9 until 11 A second embodiment according to the invention is illustrated, which remains differentiated from the first embodiment in such a way that the second component is designed as a guide element 500. In the present embodiment, an elastic guide block 550 is firmly attached as the guide element 500 in the receiving point 411. The receiving point 411 comprises a support surface 412 which can be placed in a form-fitting manner on the rear surface 310b and has a dent 413 formed therein, which serves to accommodate the storage unit 340 and/or the electrical components 350. The guide block 550 is still inserted into the dent 413, the part of which makes contact with the inner terminal 330 acts as a connecting part 510 and the part of which protrudes from the edge on the +Y side of the substrate 310 acts as an epitaxial part 530. Specifically, a fence structure (e.g., bulge or frame) for delimiting the guide block 550 may be formed in the dent 413 so that the elastic deformation of the guide block 550 enhances the interaction of the guide block 550 with the fence structure and/or the chip 300. In the present embodiment, the conductive block 550 is made of conductive silicone.

It can also be designed that the edge of the guide block 550 pointing towards the rear surface 310b is formed with a connection collar 551, the end of which presses against the inner terminal 330 acts as a connection part 510 and the end of which extends to the epitaxial part 530 acts as an external contact zone 520, to promote electrical connection between the printer side corresponding contact pins with the inner terminal 330 (not shown). The connection collar 551 can act analogously as a guide wire, exclusively via which electrical signals are transmitted between the printer-side contact pins and the inner terminal 330 instead of other segments of the guide block 550 in order to improve the efficiency of signal transmission.

The mounting direction of the ink cartridge 400 is considered a -Z direction (same as the above-mentioned P direction). If the color cartridge 400 is displaced in the -Y direction in the cartridge mounting zone 90, the further displacement is limited by the fact that the contact pins complementary to the external contact zone 520 press against the -Y side of the substrate 310. It is also conceivable that the substrate 310, as in the previous embodiment, is formed with a gap 311, which is formed as a through groove in order to limit further displacement of the ink cartridge 400 in the +Y direction. Due to the fact that the external contact zone 520 is located outside the substrate 310 and there is still a certain surface deviation between the external contact zone 520 and the contact zones of the four external terminals 320, it is almost impossible for the droplet of printer inks or other conductive foreign matter to establish an electrical connection between the external contact zone 520 and the To bring about contact zones of the external terminals 320. This means that the chip 300 in the fully assembled state does not remain vulnerable to possible short circuits due to external influences. Furthermore, the projection of the external contact zone 520 aimed at the front surface 310a does not lie on the connecting line between the second contact zone 370a and the third contact zone 380a. It is also conceivable that the guide block 550 is attached to the -Y side of the substrate 310 and therefore replaces the first clamp and/or second clamp.

With reference to a third embodiment

In 12 the chip is shown with reference to the third embodiment according to the invention. How 12 As can be seen from this, the substrate 120 has a front surface 120a, a rear surface 120b, a left flank 120c, a right flank 120d, a surface 120e, a lower surface 120f and a first side 1201d parallel to the right flank 120d and a second side 1202d. The front surface 120a lies opposite the rear surface 120b, or on the +X side of the rear surface 120b. The left flank 120c lies opposite the right flank 120d, or on the side of the -Y axis of the right flank 120d. The surface 120e lies opposite the lower surface 120f, or on the side of the +Z axis of the lower surface 120f. The first side 1201d is arranged parallel to the second side 1202d and lies on the -Y axis side of the second side 1202d.

The memory unit can be inserted into one or more surfaces of the substrate 120, but preferably into the back surface 120b. There is no specific restriction on the profiling of the chip 100, so that depending on the construction, the chip 100 can be designed to be rectangular, tangentially rectangular, rounded rectangular, T-shaped, trapezoidal or as a parallelogram. Furthermore, there is no restriction on the positioning of the memory unit, so that the memory unit is positioned on the rear end of the chip 100 adjacent to the P direction, or on the front end of the chip 100 adjacent to the P direction, or in the middle of the chip 100 can be used. The industry professionals can carry out the specific arrangement depending on the construction.

How out 12 and 13 As can be seen, the chip 100 is provided with centering holes. In the present embodiment, the chip 100 comprises a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are all formed as through holes in the substrate 120, or continuously between the front surface 120a and the back surface 120b of the substrate 120 . The first hole 121 and the second hole 122 are the same as the stop part 312 in the first embodiment. The first bore 121 is a rectangular dent from the surface 120e to the lower surface 120f, while the second bore 122 is formed as a through hole in the area of the front surface 120a or the rear surface 120b of the substrate 120 adjacent to the lower surface 120f. The chip 100 can then be fixed in the ink cartridge 10 through the first hole 121 and/or the second hole 122. Typically, the first stop pin 121a and the second stop pin 121b on the cartridge body 50 of the ink cartridge 10 fit together with the first hole 121 and the second hole 122 in a prominent manner. The chip 100 is then welded to the cartridge body 50 using a thermal welding head. The first stop pin 121a and the second stop pin 121b are the same as the stop pin 414 in the first embodiment.

How out 13 As can be seen, the color cartridge 10 for receiving the chip 100 according to the present embodiment is provided with a corresponding chip mounting zone (analogous to the receiving point 411 in the first embodiment), which has a first stop pin 121a, a second stop pin 122a and a rib part 310c, where the first stop pin 121a and the second stop pin 121b fit together with the first hole 121 and the second hole 122 in a prominent manner. The chip 100 is then welded to the cartridge body 50 using a thermal welding head.

The number of centering holes is not limited here. One centering hole (e.g. a second hole 122) or two or more than two centering holes may be provided. There are also no restrictions on the profiling of the center hole. Therefore, the centering hole can be designed as a round hole, a square hole or an irregular hole. There are also no restrictions on the profiling and number of stop pins and limiting parts.

In the embodiment according to the invention, five terminals are preferably provided, but there can be more. The five terminals include a first terminal 131 as the data terminal, a second terminal 132 as the clock terminal, a third terminal 133 as the power supply terminal, a fourth terminal 134 as the reset terminal, and a fifth terminal 135 as the ground terminal.

• Die erste Klemme 131 (Datenklemme) dient zum Senden oder Empfangen von Daten/Signale und noch zum Detektieren eventuellen Kurzschlusses mindestens an einer Klemme unter der ersten Klemme 231, zweiten Klemme 232, dritten Klemme 233 und vierten Klemme 234.

The functionality of each individual terminal is defined as follows:

• The first terminal 131 (data terminal) is used to send or receive data/signals and to detect any short circuit at least on one terminal among the first terminal 231, second terminal 232, third terminal 233 and fourth terminal 234.

The second terminal 132 (clock terminal) is used to receive clock signals.

The third terminal 133 (power supply terminal) is used to include mains potential that deviates from ground potential (for example 3.6 V or 3.3 V) so that the storage unit (not shown) is supplied with a mains voltage.

The fourth terminal 134 (reset terminal) is used to reset the internal data of the wafer.

The fifth terminal 135 (ground terminal) is used to include a ground potential.

A first spacer part 123 is formed between the second clamp 132 and the third clamp 133, but there is no restriction on its design. In the present embodiment, the first spacer part 123 is formed as a slot passing between the front surface 120a and the back surface 120b of the substrate 120. The first side 1201d is located in the first spacer part 123, or parallel to the right flank 120d. Certain terminals are installed in the front surface 120a, so that the front surface 120a is considered a first terminal panel. Certain terminals are installed in the first side 1201d, so that the first side 1201d is considered a second terminal panel. The substrate 120 is further provided with a gap where the second side 1202d with certain terminals installed lies, so that the second side 1202d is considered a third terminal array.

How out 12 As can be seen, the second terminal 132, the third terminal 133 and the fourth terminal 134 are all installed in the front surface 120a of the substrate 120, while the first terminal 131 is installed in the second terminal array, and the fifth terminal 135 is installed in the third terminal array.

How out 14 until 16 As can be seen, the two rectangular directionality are each defined as a first direction and a second direction. In the present embodiment, the first direction is considered a Z direction and the second direction is considered an X direction. The two straight lines perpendicular along the surface of the substrate 120 in the chip 100 are each defined as a first imaginary line C1 and a second imaginary line C2. The first imaginary line C1 is defined as an extension line along the first direction, while the second imaginary line C2 is defined as an extension line along the second direction. When installing the chips 100 according to the present embodiment into the ink cartridge 10, the rib portion 310c will raise the side of the chip adjacent the fourth terminal 134 along the +X axis. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones A2, A3 from the second terminal 132 and the third terminal 133 then on the second imaginary line C2, and the contact zones A1, A4, A5 from the first terminal 131, the fourth terminal 134 and the fifth terminal 135 then outside the second imaginary line C2.

In the present embodiment, the first clamp 131, second clamp 132, third clamp 133 and fourth clamp 134 are installed in different surfaces, expediently in order to prevent any foreign bodies or friction residues that may accumulate or adhere to the first clamp 131 from being pulled away from the spacer part 123 due to gravity peel off from the surface of the substrate 120 and then fall onto the contact zones of the other terminals so that the foreign matter or friction residue adheres to any one of the first terminal 131 and the second terminal 132, the third terminal 133 and the fourth terminal 134 and then one cause short circuit. It should be noted that foreign objects include, but are not limited to, conductive liquids such as ink and conductive solids such as wires, staple leads and pencil leads, friction residues.

Furthermore, the connection robustness of the individual contact pins with corresponding terminals can be ensured by the substrate 120 of the chip 100 being arranged obliquely relative to the front end face of the cartridge body 50. In addition, the pressing force between the fourth contact pin 914 and the fourth terminal 134 is increased in order to maintain the electrical connection robustness of the fourth contact pin 914 with the fourth terminal 134 and to prevent poor contacts of the individual contact pins with corresponding terminals of the chip 100 due to possible external environmental influences such as vibrations or shocks in the operation of the printing consumables.

How out 16 As can be seen, when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment, the first contact pin 911 inserts into the first spacer part 123 in the cartridge mounting zone 90 so that the first segment 911a electrically connects to the first terminal 131. While the fifth contact pin 915 simultaneously electrically connects to the fifth terminal 135, the other terminals will each electrically connect to a remaining contact pin.

The first clamp 131 is installed in the first side 1201d of the first spacer part 123. When the first terminal 131 is in a plane on the first side 1201d, the zone for contact with the fourth surface portion 911a4 of the first contact pin 911 is a plane. When the first terminal 131 is located in a curved surface or a bulge, the zone for contact with the fourth surface portion 911a4 of the first contact pin 911 is a point or a line (see also shaping and positioning of the contact zone A1 with reference to 15 ).

The fifth terminal 135 is installed in the second side 1202d. When the fifth terminal 135 is in a plane on the second side 1202d, the zone for contact with the fourth surface portion 915a4 of the fifth contact pin 915 is a plane. When the fifth terminal 135 is in a curved surface or a bulge, the zone for contact with the fourth surface portion 915a4 of the fifth contact pin 915 is a point or a line (see also Shaping and Positioning of the Contact Zone A5 with reference to 15 ).

With reference to a fourth embodiment

A fourth embodiment will be described below, which remains different from the third embodiment as follows.

How out 17 and 18 As can be seen, the substrate 120 is provided with a third side 1201c parallel to the left flank 120c, where certain terminals are installed and is therefore considered a fourth terminal field. The right flank 120d of the substrate 120 is provided with certain terminals and is therefore considered a fifth terminal field. In the present embodiment, the first terminal is 131 of the chip 100 in the fourth terminal field, while the fifth terminal 135 is in the right flank 120d, and the remaining terminals are in the front surface 120a. The coordinates of the first clamp 131 lie in the Y axis between the second clamp 132 and the third clamp 133. In the two-dimensional view, the two rectangular straight lines are each defined as a first imaginary line C1 and a second imaginary line C2. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones from the second terminal 132, the third terminal 133 and the fourth terminal 134 then on the second imaginary line C2, and the contact zones from the first terminal 131 and the fifth terminal 135 then outside the second imaginary line C2.

19 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the fourth embodiment according to the invention 19 As can be seen, the third surface area of the first segment 911a of the first contact pin electrically connects to the first terminal 131 when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90. While the fifth contact pin 915 simultaneously electrically connects to the fifth terminal 135, the other terminals will each electrically connect to a remaining contact pin.

The first terminal 131 is installed in the third side 1201c. When the first terminal 131 is in a plane on the third side 1201c, the zone for contact with the third surface portion 911a3 of the first contact pin 911 is a plane. When the first terminal 131 is in a curved surface or a bulge, the zone for contact with the third surface area 911a3 of the first contact pin 911 is a point or a line (see also shaping and positioning of the contact zone A1 with reference to 17 ).

The fifth terminal 135 is installed in the right flank 120d. When the fifth terminal 135 is in a plane on the right flank 120d, the zone for contact with the fourth surface area 915a4 of the fifth contact pin 915 is a plane. When the fifth terminal 135 is located in a curved surface or a bulge on the right flank 120d, the zone for contact with the fourth surface area 915a4 of the fifth contact pin 915 is a point or a line (see also shaping and positioning of the contact zone A5 with reference to 18 ).

With reference to a fifth embodiment

A fifth embodiment will be described below, which remains different from the third embodiment as follows.

How out 20 and 21 As can be seen, the upper wall of the first spacer part 123 (the slot) between the second clamp 132 and the third clamp 133 is formed with a first inclined surface 1201f, wherein the first clamp 131 is preferably installed in the first inclined surface 1201f. The second inclined surface 1202f is formed in the top wall of the gap of the substrate 120, with the fifth clamp 135 installed in the second inclined surface 1202f. It should be noted that the inclination angles and structures of each of the first inclined surface 1201f and the second inclined surface 1202f remain complementary to the first surface area of the corresponding contact pin. Specifically, the first clamp 131 can be inserted in a plane of the first inclined surface 1201f, the inclination angle of the first inclined surface 1201f being greater than the inclination angle of the first surface region 911a1 of the first contact pin 911. In that case, the profiling and positioning of the contact zone A1 of the first terminal 131 can be made with reference to 20 be designed, wherein the contact zone A1 of the first terminal 131 makes contact with the second surface area 911a2. The first clamp 131 can still be installed in a curved surface or a bulge in the first inclined surface 1201f, so that the corresponding profiling and positioning of the contact zone A1 as illustrated in 20 be designed, wherein the contact zone A1 of the first terminal 131 makes contact with the first surface area 911a1 or the second surface area 911a2. In the present embodiment, the first clamp 131, fifth clamp 135, second clamp 132, third clamp 133 and fourth clamp 134 are installed in different surfaces, expediently to avoid that foreign bodies or friction residues that may accumulate or adhere to the first clamp 131 due to gravity from the spacer part 123 from the surface of the substrate 120 and then fall onto the contact zones of the other terminals, so that the foreign matter or friction residues are attached to any one of the first terminal 131 and the second terminal 132, the third terminal 133 and the fourth terminal 134 stick and then cause a short circuit. It should be noted that foreign objects include, but are not limited to, conductive liquids such as ink and conductive solids such as wires, staple leads and lead pen leads, friction residues, which can cause possible short circuits between the individual terminals. Furthermore, the connection robustness of the individual contact pins with the inclined surface 1202f and the terminals installed therein can be secured by obliquely arranging the substrate 120 of the chip relative to the front end surface of the cartridge body 50 at an a-angle. In addition, the pressing force between the fourth contact pin 914 and the fourth terminal 134 is increased in order to ensure the electrical connection robustness of the fourth contact pin 914 with the fourth terminal 134 and to prevent short circuits on the chip or poor contacts of the individual contact pins with corresponding terminals of the chip 100 possible external environmental influences such as vibrations or shocks during operation of the printing consumable.

How out 21 As can be seen, when all the contact zones of the terminals individually installed in the substrate are projected onto the second imaginary line C2, the contact zones of some terminals then project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, So the contact zones from the second terminal 132, the third terminal 133 and the fourth terminal 134 then on the second imaginary line C2, and the contact zones from the first terminal 131 and the fifth terminal 135 then the outside of the second imaginary line C2.

22 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the fifth embodiment according to the invention 21 As can be seen, when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment, the first contact pin 911 inserts into the cartridge mounting zone 90 in a slot of the first spacer part 123 so that the first surface area of the first segment 911a with the first clamp 131 electrically connects. While the first surface area of the first segment 915a of the fifth contact pin 915 electrically connects to the fifth terminal 135, the other terminals will each electrically connect to a remaining contact pin.

With reference to a sixth embodiment

A sixth embodiment will be explained below, which remains different from the fifth embodiment as follows.

How 23 , 24 As can be seen, a first spacer part 123 and a second spacer part 124 are formed between the second clamp 132 and the fourth clamp 134, the first spacer part 123 located in the Z direction lying above the second spacer part 124 and continuous and trapezoidal with the second spacer part 124 connected is. The upper wall of the first spacer part 123 is defined as a first inclined surface 1201f, the inclination angle of which preferably matches the first surface area of the corresponding contact pin 911, with the first clamp 131 installed in the first inclined surface 1201f. The third clamp 133 is installed in the right wall surface 1202c of the second spacer part 124. The remaining terminals are installed in the front surface 120a, with the fifth terminal in the front surface 120a proximate to the right flank 120d and facing away from the remaining four terminals. The third terminal 133 is installed in the right wall surface 1202c. When the third terminal 133 is located in a plane of the right wall surface 1202c, the zone for contact with the third surface portion 913a3 of the third contact pin 913 is a plane. When the third terminal 133 is located in a curved surface or a bulge in the right wall surface 1202c, the zone for contact with the fourth surface portion 913a3 of the fifth contact pin 913 is a point or a line (see also Shaping and Positioning of the Contact Zone A3 with reference to 23 ). In the two-dimensional view, the two rectangular straight lines are each defined as a first imaginary line C1 and a second imaginary line C2. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones from the second terminal 132, the fourth terminal 134 and the fifth terminal 135 then on the second imaginary line C2, and the contact zones from the first terminal 131 and the third terminal 133 then outside the second imaginary line C2. As a result, two adjacent terminals in the Y axis are positioned heterogonally or at a further distance apart to avoid possible short circuits due to a possible foreign body or friction residue at any one of the first terminal 131 and the second terminal 132, the third terminal 133 and the fourth terminal 134 is liable to be avoided. This increases the operational reliability of the chip, which can cause possible short circuits between the individual terminals.

25 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the sixth embodiment according to the invention 25 As can be seen, when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment, the first contact pin 911 inserts into the cartridge mounting zone 90 in a slot of the first spacer part 123 so that the first surface area of the first segment 911a with the first clamp 131 electrically connects. While the third contact pin 913 simultaneously inserts into the slot of the second spacer part 124 and electrically connects to the third terminal 133. The other terminals will each be electrically connected to a remaining contact pin.

With reference to a seventh embodiment

A seventh embodiment will be explained below, which remains different from the sixth embodiment as follows.

How out 26 and 27 As can be seen, the first terminal 131 to the fourth terminal 134 are arranged analogously to the sixth embodiment. In the present embodiment, the fifth terminal 135 is installed in the right flank 120d, away from the remaining four terminals. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones from the second terminal 132 and the fourth terminal 134 then to the second imaginary line C2, and the contact zones from the first terminal 131, the third terminal 133 and the fifth terminal 135 then outside the second imaginary line C2. The advantages are analogous to those of the sixth embodiment and will no longer be described. The fifth terminal 135 is installed in the right flank 120d. When the fifth terminal 135 is in a plane on the right flank 120d, the zone for contact with the fourth surface area 915a4 of the fifth contact pin 915 is a plane. When the fifth terminal 135 is located in a curved surface or a bulge on the right flank 120d, the zone for contact with the fourth surface area 915a4 of the fifth contact pin 915 is a point or a line (see also shaping and positioning of the contact zone A5 with reference to 27 ).

28 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the seventh embodiment according to the invention 28 As can be seen, when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment, the first contact pin 911 inserts into the cartridge mounting zone 90 in a slot of the first spacer part 123 so that the first surface area of the first segment 911a with the first clamp 131 electrically connects. While the third contact pin 913 simultaneously inserts into the slot of the second spacer part 124 and electrically connects to the third terminal 133. While the fifth contact pin 915 simultaneously electrically connects to the fifth terminal 135, the other terminals will each electrically connect to a remaining contact pin.

Referring to an eighth embodiment

An eighth embodiment will be explained below, which remains different from the third embodiment as follows.

How out 29 and 30 As can be seen, the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 are all installed in the front surface 120a of the substrate 120. In the present embodiment, the coordinates of each of the first terminal 131, second terminal 132, third terminal 133 and fourth terminal 134 are not identical to each other in the Y axis, while the first terminal 131 to the fourth terminal 134 and the second terminal 132 to the third clamp 133 in the Z-axis with respect to the coordinate system, however, are the same, with the first clamp 131 remaining different from the second clamp 132 in the Z-axis with respect to the coordinate system. In the area of the front surface 120a adjacent to the right flank 120d, a recess 1201a is formed, which appears as a dent from the front surface 120a to the rear surface 120b in order to accommodate the fifth clamp 135. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, not all of the contact zones project onto the second imaginary line C2, i.e. the contact zones from the first terminal 131, because the fifth terminal 135 is installed in the recess 1201a to the fourth terminal 134 on the second imaginary line C2, and the contact zone of the fifth terminal 135 then outside the second imaginary line C2. When inserting the color cartridge 10 together with the mounted chip 100 according to the present embodiment into the cartridge mounting zone 90, the recess 1201a can determine the fifth contact pin 915 in the correct position in order to secure contact with the fifth contact pin 915. The recess 1201a can be formed either as a dent area in the substrate 120 or as a second component outside the substrate 120. The second component connects the corresponding contact pins on the printer side and the inner terminal 330 electrically, i.e. the second segment is partially electrically connected to the fifth contact pin 915 on the printer side and the inner terminal 330. The recess 1201a is formed in the second component and is therefore manufactured separately from the substrate 120 and then closed with the substrate a component of the complete chip or the color cartridge. Such an arrangement can eliminate the manufacturing difficulty of the recess 1201a in the substrate 120 and reduce the risk of poor contact due to the eventual processing errors.

How out 31 As can be seen, when installing the color cartridge 10, the fifth contact pin 915 slides together with the fully assembled chip 100 according to the present embodiment into the cartridge mounting zone 90 into the recess 1201a and then connects to the fifth terminal 135. The remaining terminals each press against one other Contact pin and each connect to the electrical.

It should be noted that the chip holder 220 mating with the chip 100 according to the present embodiment is described with reference to 32 with a first stop pin 221a and the second stop pin 221b (analogous to stop pin 414 in the first embodiment), the first stop pin 221a and the second stop pin 221b having the first bore 121 and the second bore 122 (analogous to stop part 312 in the first embodiment) fit together in an outstanding way. The chip 100 is then welded to the chip holder 220 using a thermal welding head. The chip holder 220 can be snap-connected to or removed from a consumable (not shown) of the chip. With the chip 100 attached to the chip holder 220, the removable assembly of the chip 100 with the color cartridge 10 is facilitated in order to protect the chip 100 against possible damage or data loss and to ensure the proper operation of the color cartridge 10 and the printer. The chip holder 220 can also act as the second component. In this case, the fifth terminal 135 is installed on the chip holder 220, the chip holder 220 electrically connecting the printer-side fifth contact pin 915 to the inner terminal 330.

Referring to a ninth embodiment

A ninth embodiment will be explained below, which remains different from the eighth embodiment as follows.

How out 33 As can be seen, the substrate 120 comprises a plane region and a curved surface 130a, with the front surface 120a being located in the plane region of the substrate 120. Starting from the direction perpendicular to the front surface 120a, the curved surface 130a is formed in the upper region of the front surface 120a adjacent to the surface 120e along the +X axis. Certain terminals are installed in the curved surface 130a, so that the curved surface 130a is considered a sixth terminal panel.

How out 34 As can be seen, the second terminal 132, third terminal 133 and fifth terminal 135 are all installed in the front surface 120a of the substrate 120. The first clamp 131 and the fourth clamp 134 are installed in the curved surface 130a of the substrate 120, while the fifth clamp 135 is installed on a side of the front surface 120a adjacent to the right flank 120d, that is, away from the remaining four clamps. When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones from the second terminal 132, the third terminal 133 and the fifth terminal 135 then on the second imaginary line C2, and the contact zones from the first terminal 131 and the fourth terminal 134 then outside the second imaginary line C2.

35 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the ninth embodiment according to the invention 35 As can be seen, when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90, the contact pin heads of the first contact pin 911 and the fourth contact pin 914 each press against the curved surface 130a, so that the first surface area is in the first segment 911a of the first contact pin 911 electrically connects to the first terminal 131, while the fourth contact pin 914 electrically connects to the fourth terminal 134 and the other terminals each press against another contact pin and each electrically connect to it. The first contact zone A1 of the first terminal 131 and the fourth contact zone A4 of the fourth terminal 134 can be as shown in 37 profile and position so that the first contact zone A1 of the first clamp 131 makes contact with the second surface area 911a2, while the second surface area 914a2 of the fourth contact pin 914 contacts the fourth contact zone A4 of the fourth clamp 134. The first terminal 131 and The fourth clamp 134 can still be attached in a curved surface or a bulge, so that a contact zone with the same profiling and positioning as illustrated in 37 is designed, wherein the contact zone A1 of the first terminal 131 makes contact with the first surface region 911 a1 or the second surface region 911 a2, while the fourth contact zone A4 of the fourth terminal 134 contacts the first surface region 914a1 or the second surface region 914a2 of the fourth contact pin 914 .

The variant of the chip holder 220 that fits together with the chip 100 according to the present embodiment, which is different from the eighth embodiment, will be explained below. How out 36 , 37 As can be seen, the mounting zone is provided with a support frame 221c, which in the present embodiment is square with an inclined surface whose angle of curvature looks the same as the curved surface 130a of the chip according to the present embodiment. When mounting the chip 100 on the chip holder 220, the support frame 221c provides a supporting effect. The chip according to the present embodiment can also be first attached to the chip holder 220 in a manner as in the eighth embodiment and the chip holder 220 can then be installed in a consumable cartridge, although this will not be detailed here.

The substrate of the chip 100 according to the present embodiment can alternatively be made of bendable, flexible material. Alternatively, the curved surface 130a may be formed not in a hard substrate 120 but in the second component. The second component can also be made of flexible material, or of a hard material, provided that there is a certain angle to the substrate 120. The first terminal 131 and fourth terminal 134 are installed in the second component so that the second segment connects to the printer-side corresponding contact pins and the inner terminal 330.

Referring to a tenth embodiment

A tenth embodiment will be explained below, which remains different from the ninth embodiment as follows.

The first terminal 131 to the fourth terminal 134 are positioned analogously to the ninth embodiment, which will not be detailed here.

How out 38 and 39 As can be seen, the area of the right flank 120d of the substrate 120 adjacent to the lower surface 120f is formed along the -Y axis as a gap which has a fourth side 1203d for receiving the installed fifth clamp 135. The fifth terminal 135 is installed in the fourth side 1203d. If the fifth terminal 135 lies in a plane on the fourth side 1203d, the contact area with the fourth surface area of the fifth contact pin 915 is a plane. If the fifth terminal 135 lies in a curved surface or a bulge, the contact area with the fourth surface area of the fifth contact pin 915 is a point or a line (see also shaping and positioning of the contact zone A5 with reference to 39 ).

When projecting all the contact zones of the terminals individually installed in the substrate onto the second imaginary line C2, the contact zones of some terminals project onto the second imaginary line C2, and the contact zones of the other terminals onto the outside of the second imaginary line C2, i.e. the contact zones from the second terminal 132 and the third terminal 133 then to the second imaginary line C2, and the contact zones from the first terminal 131, the fourth terminal 134 and the fifth terminal 135 then outside the second imaginary line C2.

40 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the tenth embodiment according to the invention 40 As can be seen, the contact pin heads of the first contact pin 911 and the fourth contact pin 914 press against the curved surface 130a when installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90, so that the contact pin heads of the first contact pin 911 and Press the fourth contact pin 914 onto the curved surface 130a. As a result, the first segment 911a of the first contact pin 911 electrically connects to the first terminal 131, and the fourth contact pin 914 to the fourth terminal 134, and the fifth contact pin 915 to the fifth terminal 135. The remaining terminals each press against a remaining contact pin and connect to it electrically.

The chip according to the present embodiment can also be attached to the chip holder in the same way as in the ninth embodiment and the chip holder can then be installed in a consumable cartridge, which will not be detailed here.

Alternatively, the substrate of the chip 100 according to the present embodiment can be made of bendable, flexible material.

Referring to an eleventh embodiment

How out 41 until 46 As can be seen, the color cartridge 3 here comprises a cartridge body 5, a chip holder 6, a spring element 7 and a chip 4. The chip 4 is installed in the front surface of the color cartridge 3 (front surface of the cartridge body 5) and also has terminals 45 for contact with the contact pins 91a provided. If the color cartridge 3 is inserted into the cartridge mounting zone along the mounting direction, the front surface of the color cartridge 3 faces an inner wall of the cartridge mounting zone provided with the contact pins 91a, so that the terminals 45 of the chip 4 press against the contact pins 91a and thus an electrical connection of the chip 4 using an image processing device.

How out 44 and 45 As can be seen, the chip 4 comprises a front surface 41 pointing towards the contact pin block 91, a surface 43 lying above the front surface 41 and a lower surface 44 lying below the front surface 41. A plurality of terminals 45 are installed on the chip 4. In the present embodiment, these terminals 45 are each mounted in the surface 43 and the lower surface 44 of the chip 4, the terminals 45 mounted in the surface 43 of the chip 4 contacting the higher placed contact pins 91a in the contact pin block 91, while those in the lower surface 44 The terminals 45 located on the chip 4 contact the lying contact pins 91a in the contact pin block 91.

In the prior art, all conventional terminals of the chip are installed in the front surface of the chip so that any foreign objects such as conductive solids such as wires, staple leads, pencil leads, friction residues or conductive liquids such as ink can penetrate into the chip, resulting in short circuit between terminals and contact pins. In the present embodiment, however, the terminals of the chip are divided into the surface and the bottom surface, which can limit possible adhesion of foreign bodies between terminals and contact pins to a certain extent. In particular, some terminals are located in the bottom surface of the chip and can escape the foreign body, so that short circuits do not occur and the durability of the chip is ensured.

How out 43 As can be seen, the top of the chip holder 6 is formed with a dent 61 on which the chip 4 is installed. The dent 61 is provided with certain heat dissipation performance and can provide a certain clearance for the contacts of the contact pins 91a with the terminals 45 placed in the lower surface 44 of the chip 4, the memory unit and the electrical components. The chip 4 can be attached to the chip holder 6 by gluing, welding or snap connection. The front surface 41 of the chip 4 may remain somewhat prominent relative to the front surface of the chip holder 6 to promote the contacts of the contact pins 91a with the terminals 45 installed in the lower surface 44 of the chip 4. The front surface 41 of the chip holder 6 can extend downwards (see 44 ), accordingly, a nose 62 is formed behind the downwardly extending front surface of the chip holder 6, to which one end of the spring element 7 is fixed, while the other end of the spring element 7 is fastened to the cartridge body 5. The spring element 7 can be a spring. When the chip holder 6 fits together with the spring element 7 in this way, the chip 4 can be pulled out forwards and backwards, i.e. in the cartridge mounting zone in a direction that approaches or turns away relative to the inner wall of a contact pin 91a. Such elastic extensibility is advantageous for mounting the ink cartridge 3 into the cartridge mounting zone and can thus avoid mutual interference between the front surface of the chip 4 and the contact pins 91a.

Referring to a twelfth embodiment

How out 47 and 48 As can be seen, the present embodiment is approximately the same as the eleventh embodiment, but with a slight difference. In the present embodiment, several terminals 45 are each placed in the front surface 41 and the lower surface 44 of the chip 4, the terminals 45 attached in the front surface 41 of the chip 4 contacting the higher placed contact pins 91a in the contact pin block 91, while those in the lower surface 44 The terminals 45 located on the chip 4 contact the lying contact pins 91a in the contact pin block 91. Like the dashed lines in 47 represent, in the present embodiment the contact points of the terminals 45 installed in the front surface 41 of the chip 4 to the contact pins 91a and the contact points of the terminals 45 installed in the bottom surface 44 of the chip 4 to the contact pins 91a are in two different erected first imaginary lines C1. If these two first imaginary lines C1 project onto a horizontal plane perpendicular to them, the two second imaginary lines continuous in the horizontal plane are spaced apart from one another in the forward and backward directions, i.e. do not overlap. Compared to the eleventh embodiment, the clamps 45 are not installed in the surface 43 but in the front surface 41. Since the corresponding contact pins do not contact the surface 43 but rather the front surface 41, there is no engagement between the chip 4 and those placed higher up Contact pins when removing the color cartridge 3 from the cartridge assembly zone, which can make dismantling the color cartridge 3 easier.

Referring to a thirteenth embodiment

How out 49 until 51 As can be seen, the present embodiment is approximately the same as the eleventh embodiment, but with a slight difference. In the present embodiment, the front surface 41 of the chip 4 is formed with a groove 42 where the terminal 45 installed in the front surface 41 of the chip 4 lies. This makes it possible to prevent the terminal 45 installed in the front surface of the chip 4 from being touched or hit by foreign objects in order to protect the chip 4 or the terminal 45. Like the dashed lines in 51 represent, in the present embodiment the contact points of the terminals 45 installed in the front surface 41 of the chip 4 to the contact pins 91a and the contact points of the terminal 45 installed in the bottom surface 44 of the chip 4 to the contact pins 91a are in two different erected first imaginary lines C1. If these two first imaginary lines C1 project onto a horizontal plane perpendicular to them, the two second imaginary lines continuous in the horizontal plane are spaced apart from one another in the forward and backward directions, i.e. do not overlap.

In the prior art, all conventional terminals of the chip are installed in the front surface of the chip so that any foreign objects such as conductive solids such as wires, staple leads, pencil leads, friction residues or conductive liquids such as ink can penetrate into the chip, resulting in short circuit between terminals and contact pins. In the present embodiment, however, the terminals of the chip are spaced apart in the groove, which can limit possible adhesion of the foreign bodies between the terminals and contact pins to a certain extent, so that no short circuits occur and the durability of the chip is ensured.

How out 49 As can be seen, in some embodiments the groove 42 is formed with an arcuate inner wall, where the terminals 45 installed in the front surface 41 of the chip 4 lie. This makes it easier to contact the arcuate terminals 45 with the contact pins 91a.

Referring to a fourteenth embodiment

This embodiment looks approximately the same as the thirteenth embodiment, but with a slight difference. In the present embodiment, several terminals 45 are each mounted in the surface 43 and front surface 41 of the chip 4, the terminals 45 mounted in the surface 43 of the chip 4 contacting the higher placed contact pins 91a in the contact pin block 91, while those in the front surface 41 of the chip 4 Chips 4 located terminals 45 contact the lying contact pins 91a in the contact pin block 91.

In the present embodiment, at least one clamp 45 is installed in the surface 43 or the bottom surface 44 of the chip 4. As a result, any contact or abutment surface of the terminals 45 installed in the front surface 41 of the chip 4 with foreign bodies can be reduced. In comparison to the conventional state of the art, the chip 4 can be protected from damage during the assembly or transport process in order to achieve a robust electrical connection of the chip 4 to an image processing device and thus ensure good print quality.

Referring to a fifteenth embodiment

How out 52 and 53 As can be seen, the chip 4 in the present embodiment is provided with a substrate where four terminals other than the ground terminals 5a are installed in the front surface of the chip 4, one each as a data terminal (analogous to the first terminal 360 in the first embodiment), one as a reset terminal (analogous to the fourth terminal 390 in the first embodiment), one as a clock terminal (analogous to the second terminal 370 in the first embodiment), and one as a power supply terminal (analogous to the third terminal 380 in the first embodiment), where The individual positions of these four terminals are defined as a mounting field for the terminals other than the ground terminals. The chip 4 is further provided with an internal ground terminal (not shown, analogous to the internal terminal 330 in the first embodiment) installed in the rear surface of the chip 4. The internal ground terminal (analogous to internal terminal 330 in the first embodiment) can be installed in the rear surface of the chip 4, or preferably in or next to a mounting field for the terminals other than the ground terminals.

The inner wall of the cartridge mounting zone 90 (analogous to the first side wall 90c in the first embodiment) is formed with a contact pin block 91 in which five contact pins are attached, i.e. a first contact pin 911, a second contact pin 92, a third contact pin 913, a fourth contact pin 914 and a fifth contact pin 915. Below this, four contact pins work with the terminals apart from the ground terminals 5a of the chip 4 together, namely a data contact pin (analogous to the first contact pin 911), a reset contact pin (analogous to the fourth contact pin 914), a clock contact pin (analogous to the second contact pin 92) and a power contact pin (analogous to the third contact pin 913), which are all collectively referred to as contact pins 22e except for the ground pin, while the last contact pin is defined as ground pin 21e (analogous to the fifth contact pin 915).

If the color cartridge 3 is inserted into the cartridge mounting zone 90 in the mounting direction, the front surface of the color cartridge 3 faces an inner wall provided with the contact pin (analogous to the first side wall 90c in the first embodiment) of the cartridge mounting zone 90, so that the four terminals other than the ground terminals 5a of the chip 4 on four contact pins 22e other than the ground pin press and so an electrical connection of the chip 4 with an image processing device is established. In the present embodiment, “forward” is a direction pointing from the ink cartridge to the contact pin block 91, and “backward” is a direction pointing from the contact pin block 91 to the ink cartridge. The “front surface” means a surface facing the contact pin block 91, and the “back surface”, on the other hand, means a surface facing away from the contact pin block 91.

In the conventional state of the art, the ground pin 21e (analogous to the fifth contact pin 915) is electrically connected directly to the chip. In the present embodiment, the ground pin 21e is electrically connected to the chip not directly but indirectly via the chip holder 6 (analogous to the second component in the first embodiment), the chip holder 6 being provided with an external contact zone (also called ground connection) so that the Chip holder 6 each contacts the internal ground terminal of the chip (analogous to the internal terminal 330 in the first embodiment) and the ground pin 21e (analogous to the fifth contact pin 915). This means that the conventional electrical continuity connection between the ground terminal and the ground pin 21 e is replaced by the electrical continuity connection according to the invention between the ground terminal, the chip holder 6 and the ground pin 21 e. In the present embodiment, the ground pin 21 e is connected to a conductive segment of the chip holder 6, which also contacts the internal ground terminal of the chip. In the present embodiment, the complete chip holder 6 may be made of electrically conductive materials such as metal, conductive plastic or conductive silicone. In the further embodiments, the chip holder 6 can be partially made of electrically conductive materials, provided that the electrical connection of the chip holder 6 to the ground pin 21e and the internal ground terminal of the chip is also successfully established. The chip holder 6 can be partially fixed or coupled to the substrate of the chip. The chip holder 6 can still be viewed as a component of the chip. The chip holder 6 can also be provided with an epitaxial part. A chip holder 6 made entirely of electrically conductive materials (analogous to the second component in the first embodiment) can be viewed as the conductive element 500 in the first embodiment.

The chip holder 6 includes a front surface facing the contact pin block 91 in the cartridge mounting zone 90 and a rear surface facing away from the contact pin block 91. For mounting, the back surface of the chip 4 is placed in a form-fitting manner on the front surface of the chip holder 6 and then attached and fixed together to the chip holder 6 by gluing, welding or snap-in connection. In the present embodiment, the chip 4 is formed with a first centering hole 41 (analogous to the stop part 312 in the first embodiment), accordingly the front surface of the chip holder 6 is formed with a first bulge 61a (analogous to the stop pin 414 in the first embodiment). . By fitting the first centering hole 41 with the first bulge 61a, a snap connection of the chip 4 to the chip holder 6 can be achieved. In further embodiments, the chip 4 cannot be fixed through the first centering hole 41 but rather by gluing (see 58 ). Alternatively, the first bulge 61a (analogous to the stop pin 414 in the first embodiment) may be formed in the cartridge body to press or clamp the chip holder 6 between the chip 4 and the cartridge body.

After successful assembly, the internal ground terminal placed in the rear surface of the chip 4 is relatively electrically connected to the front surface of the chip holder 6. In further embodiments, the internal ground terminal may be installed elsewhere such as on an edge of the chip 4, accordingly the chip holder 6 is formed with a member such as a bulge for contact with the internal ground terminal. The internal ground terminal can still be electrically connected to the chip holder 6 in a manner of gluing or welding, provided that this also creates the electrical connection of the chip holder 6 to the internal ground terminal.

The chip 4 partially overlaps the front surface of the chip holder 6, so that a reserve area 71 is created on the chip holder 6 that cannot be overlapped by the chip 4 (analogous to the epitaxial part 530 in the first embodiment), which is the Mas sepin 21e of the cartridge mounting zone 90 (analogous to the fifth contact pin 915) is contacted. Specifically, the contact area between the reserve area 71 and the ground pin 21e is regarded as an external contact zone for electrically connecting the chip holder 6 to the ground pin 21e. With such contact with the ground pin 21e via the chip holder 6, the ground pin 21e is no longer limited to the contact surface of the conventional ground terminal and can be conveniently arranged in many flexible ways in order to enlarge the conductive surface for contact with the ground pin 21e. This ensures that the groundings are secured to a high degree, damage caused by electric shock is avoided and the proper operation of the printing device is ensured, even if the ink cartridge is not mounted in the correct position.

The reserve area 71 can be arranged in many ways. For example, the chip 4 can be formed with a through hole or a gap in an area corresponding to the conventional ground clamp, so that a reserve area 71 that cannot be overlapped by the chip 4 is created on the chip holder 6. In the current embodiment (see 52 , 53 ), the chip 4 is formed in the area corresponding to the conventional ground clamp with an edge gap 43 (analogous to the gap 311 in the first embodiment), so that a reserve area 71 is conveniently created for grounding via the ground pin 21e.

How out 54 and 55 As can be seen, the individual contact points of all terminals of the chip 4 are projected along the first imaginary line C1 onto the second imaginary line C2. Since the chip 4 has a certain thickness, a certain difference height arises between the surface (analogous to the front surface of the chip 4) of the terminal 5a except the ground terminals and the front surface of the chip holder 6, so that the contact points of the four terminals 5a except the ground terminals and the four contact pins 22e except the ground pin project onto the second imaginary line C2, and the contact points (analogous to the external contact zones in the first embodiment) each of the reserve area 71 and the ground pin 21e project outside the second imaginary line C2, the projection point of the Contact point of the ground pin 21e in the forward and backward direction is then spaced from the second imaginary line C2 at a certain distance L (analogous to the thickness of the chip 4). How out 56 and 57 As can be seen, the side where the conventional ground terminal is installed in the chip may be omitted in some present embodiments to create a much larger reserve area in the chip 4 according to the present embodiment to favor contact with the ground pin 21e.

Referring to a sixteenth embodiment

The present embodiment looks approximately the same as the fifteenth embodiment, but with a slight difference in that the fit of the chip 4 according to the present embodiment with the chip holder 6 is designed differently.

How out 59 until 65 As can be seen, the chip holder 6 according to the present embodiment has a front surface pointing towards the contact pin block 91 of the cartridge mounting zone 90 and a rear surface facing away from the contact pin block 91. The four terminals 5a except the ground terminal and the internal ground terminal (analogous to the internal terminal 330 in the first embodiment) are all installed in the front surface of the chip 4. For mounting, the front surface of the chip 4 is placed in a form-fitting manner on the back surface of the chip holder 6 and then attached together to the chip holder 6 by gluing, welding or snap-in connection. In the present embodiment, the chip 4 is formed with a second centering hole 42a (analogous to the stop part 312 in the first embodiment), accordingly the front surface of the chip holder 6 is formed with a second bulge 62a (analogous to the stop pin 414 in the first embodiment). . By fitting the second centering hole 42a with the second bulge 62a, a snap connection of the chip 4 to the chip holder 6 can be achieved.

After successful assembly, the internal ground terminal installed in the front surface of the chip 4 is relatively electrically connected to the rear surface of the chip holder 6. In further embodiments, the internal ground terminal may be installed elsewhere such as on an edge of the chip 4, accordingly the chip holder 6 is formed with a member such as a bulge for contact with the internal ground terminal. The internal ground terminal can still be electrically connected to the chip holder 6 in a manner of gluing or welding, provided that this also creates the electrical connection of the chip holder 6 to the internal ground terminal.

The chip holder 6 partially overlaps the front surface of the chip 4, so that a free zone 72 is created on the chip 4 that cannot be overlapped by the chip holder 6, which exposes at least the terminals 5a apart from the internal ground terminal of the chip 4, so that these terminals have the contact pins 22e except for the ground pin in the cartridge mounting zone 90. The area of the chip holder 6 covering the front surface of the chip 4 contacts the ground pin 21e in the cartridge assembly gezone 90 to enable an electrical connection between the chip holder 6 and the ground pin 21e. Compared with the fifteenth embodiment, the type of contact with the ground pin 21e via a portion of the chip holder 6 covering the front surface of the chip 4 can significantly expand the contact area of the ground pin 21e, avoid damage due to electric shock, and ensure the proper operation of the printing device.

How out 61 and 62 As can be seen, the individual contact points of all terminals of the chip 4 are projected along the first imaginary line C1 onto the second imaginary line C2. Since the chip holder 6 has a certain thickness, a certain difference height arises between the surface (namely front surface of the chip 4) of the terminal 5a other than the ground terminals and the front surface of the chip holder 6, so that the contact points of the four terminals 5a except the ground terminals and the four contact pins 22 except the ground pin project onto the second imaginary line C2 and the contact points (analogous to the external contact zones in the first embodiment) of the chip holder 6 project outside the second imaginary line C2, with the projection point of the contact point of the ground pin 21 in the front - and backward direction is then spaced from the second imaginary line C2 at a certain distance L (analogous to the thickness of the chip holder 6). The free zone 72 can be arranged in many different ways. With reference to 63 until 65 For example, the chip holder 6 is designed with a plurality of second holes 65, each second hole 65 exposing each terminal 5a except the ground terminals of the chip 4 in order to enable contacts with the contact pins 22e except the ground pin. Specifically, four second holes 65 and four terminals 5a are provided in addition to the ground terminals. Preferably, the bottom of every second hole 65 is designed with a ramp that slopes downwards from the back to the front, so that the contact pins for removing the color cartridge 3 slide smoothly and thus enable easy removal of the color cartridge 3 without intervention of the chip holder 6.

In the further embodiments with reference to 66 until 68 the chip holder 6 is formed with a first hole 64, which can expose all terminals 5a except the ground terminals of the chip 4 in order to enable contacts with the contact pins 22e except the ground pin. The bottom of the first bore 64 is preferably designed with a ramp that slopes downwards from the back to the front so that the contact pins for removing the ink cartridge 3 slide smoothly and thus enable easy removal of the ink cartridge 3 without intervention of the chip holder 6.

In the further embodiments with reference to 69 until 71 the chip holder 6 is designed without a through hole and, due to a reduced size, can only cover the side of the chip 4 where no terminals 5a except the ground terminals are installed, so that the terminals 5a are exposed except the ground terminals and so then the contact pins 22e except the ground terminals can contact ground pins. With such a configuration, a latching connection of the chip 4 to the chip holder 6 can be brought about by fitting a third centering hole formed in the chip 4 with a third bulge 63 formed in a flank of the chip holder 6. In comparison to the first embodiment, the area on the -Y axis of the chip is reserved, and the area on the +Y axis is replaced by the chip holder 6. The chip holder 6 made of electrically conductive materials (analogous to the second component) can be viewed as the conductive element 500 in the first embodiment. That is, the area on the +Y axis side of the chip in the first embodiment is replaced by the chip holder 6 here. The chip holder 6 can be viewed as a component of the cartridge body and can first be attached to the cartridge body (first attach the chip holder 6 to the receiving location). The chip 4 is then installed on the chip holder 6. The chip holder 6 can be referred to as a structure 52 until 71 , or as a member with a curved surface, or as a folded profile made of conductive material (for example sheet metal). The chip holder 6 can be arranged firmly (as shown in 52 until 71 ) or attach in an elastic way. The epitaxial part can deform or shift, for example into a folded sheet with a suspension segment, or into a lever shape with a suspended sheet end, or into a curved metal sheet. In the case of a chip holder 6 designed as a folded sheet metal with a suspension segment or as a lever shape with a suspended sheet metal end, the contact points / external contact zone in the reserve area 71 or on the ground pin 21e in the chip holder 6 are then designed on the part of the suspended sheet metal end or the suspension segment. In the case of a curved chip holder 6 made of a metal sheet, the external contact zone is formed at the apex of the curved section. With the chip holder 6 attached in an elastic manner, a part of the chip holder 6 (in particular the epitaxial part) can deform or shift in the -X axis or a direction of the front surface pointing towards the rear surface when a contact pin comes into contact with the chip holder 6, whereby the external contact zone 520 moves with the deformation or displacement of the chip holder 6. This allows the effective force of a contact pin against the chip holder 6 be damped in order to create a robust electrical connection between the chip holder 6 and the contact pin.

In the present embodiment, the complete chip holder 6 can be made of electrically conductive materials such as metal, conductive plastic or conductive silicone. In the further embodiments, the chip holder 6 can be partially made of electrically conductive materials, provided that the electrical connection of the chip holder 6 to the ground pin 21e and the internal ground terminal of the chip is also successfully established. Preferably, the areas of the chip holder 6 bordering the terminals 5a other than the ground terminals, for example the round areas around the first bore 64 and the second bore 65, can be made of an insulating material in order to prevent any short circuits due to incorrect contact of the contact pins other than the ground pin with the Chip holder 6 to avoid.

Referring to a seventeenth embodiment

In 72 a further embodiment according to the invention is shown with a chip 100, wherein the chip 100 has a first plate 1 (analogous to the substrate 310 in the first embodiment) and a second plate 2 (analogous to the second component in the first embodiment), while the Profiling of the substrate is not restricted and can therefore be designed by industry experts depending on the construction, for example rectangular, truncated rectangular, rounded rectangular, T-shaped, trapezoidal or as a parallelogram. The terminals are installed partly in the first plate 1, partly in the second plate 2, each terminal being formed with a contact area for contact with a corresponding contact pin on the printer. Specifically, each terminal is provided with a contact zone, which is considered a contact area where a contact pin is most likely to press against a corresponding terminal when mounting the ink cartridge 10 to the printer. The chip 100 may further comprise a flexible connector 3a, via which the first plate 1 is connected to the second plate 2 to form a complete chip. The first plate 1 may be electrically connected to the second plate 2 so that the first plate 1 and the second plate 2 share the storage unit 4a and the electrical components. Alternatively, the first plate 1 and the second plate 2 can be laid separately from one another or without an electrical connection and can also have their own storage unit, so that separate operation or signal transmission remains possible.

How out 72 As can be seen, the first plate 1 is essentially designed as a cuboid, with a first side 101 (analogous to the surface), a second side 102 (analogous to the bottom surface), a third side 103 (analogous to the front surface), and a fourth side 104 (analogous to the back surface), a fifth page 105 (analogous to the left flank) and a sixth page 106 (analogous to the right flank), with the first page 101 to the second page 102 and the third page 103 to the fourth page 104, the fifth side 105 is laid parallel to the sixth side 106. The third page 103 overlaps with the fourth page 104 in the first page 101 and the second page 102, while the fifth page 105 overlaps with the sixth page 106 in the first page 101, the second page 102, the third page 103 and the fourth page 104 overlaps. Preferably, the third side 103 and the fourth side 104 remain perpendicular to the first side 101 and the second side 102, while the fifth side 105 and the sixth side 106 remain perpendicular to the first side 101, the second side 102, the third side 103 and on the fourth page 104.

Specifically, the terminals installed in the first board include a data terminal 111a (analogous to the first terminal 360 in the first embodiment) and a reset terminal 112a (analogous to the fourth terminal 390 in the first embodiment). These clamps are at least partially installed in the second side 102 and/or first side 101. Preferably, the data terminal 111a and the reset terminal 112a are all placed in the second side 102, or alternatively in the third side 103 up to the second side 102 and/or first side 101. In the present embodiment, the data terminal 111a and the reset terminal 112a are all placed in the third side 103 to the second side 102. The contact pins 91a are electrically connected to the parts of the terminals placed in the first side 101 or second side 102, i.e. the contact zones are in the first side 101 or the second side 102. In the present embodiment, the contact pin block 91 contacts the first plate and when the color cartridge 10 is mounted in the cartridge mounting zone 90, the contact pins 91a electrically connect to the parts of the terminals placed in the second side 102, i.e. the contact zones are located in the second side 102 .

It can be further configured that the first plate 1 is further provided with a storage unit 4a or an electrical component, with no restrictions being imposed on the positioning of the storage unit 110. Preferably, the storage unit 4a is placed in the second side 102 of the first disk 1. The storage unit 4a is used to store electronic information such as color cartridge type, printer ink level and printer ink types, etc. When mounting the color cartridge 10 into the cartridge mounting zone 90 of a printer, the chip 100 electrically connects to the printer-side contact pin block 91 to enable information exchange, authentication and maintenance of the on the To enable storage unit 4a and data and/or information stored in the printer. As the printer ink in the color cartridge 10 is consumed, the printer ink level recorded on the chip 100 will change depending on the amount of printing.

Specifically, the terminals installed in the second board include a clock terminal 211 (analogous to the second terminal 370 in the first embodiment), a power supply terminal 212 (analogous to the third terminal 380 in the first embodiment), and a ground terminal 213 (analogous to that Baffle 540 or the fifth clamp in the first embodiment). These clamps are at least partially placed in the second surface 202 and/or first surface 201. Preferably, the clock terminal 211, power supply terminal 212 and ground terminal 213 are placed in the second surface 202, or alternatively in the third surface 203 up to the second surface 202 and/or first surface 201. In the present embodiment, the clock terminal 211, power supply terminal 212 and ground terminal 213 are all placed in the third surface 203 to the second surface 202. The contact pins 91a are electrically connected to the parts of the terminals placed in the first surface 201 or the second surface 202, i.e. the contact zones lie in the first surface 201 or the second surface 202. In the present embodiment, the contact pin block 91 contacts the second plate and, when the ink cartridge 10 is mounted in the cartridge mounting zone 90, the contact pins 91a electrically connect to the parts of the second terminals 21 placed in the second surface 202, i.e. lie in the second surface 202 the contact zones.

Here, the clamps installed in the first plate are at least partially placed in the first side 101 and/or second side 102, while the clamps installed in the second plate are at least partially placed in the first surface 201 and/or second surface 202. When mounting the ink cartridge 10 into the cartridge mounting zone 90, the contact pin block 91 mounted in the cartridge mounting zone 90 partially connects to the terminals placed in the first side 101 or the second side 102 and partially closes the terminals placed in the first surface 201 or the second surface 202 electrically. Since the terminals are each placed in the first plate 1 and the second plate 2, which is spaced somewhat apart from it, it is not susceptible to short circuits when mounting the ink cartridge 10 in the cartridge mounting zone 90, even if the ink cartridge 10 is not mounted in the correct position due to any contact pin 91a placed in the cartridge mounting zone 90 touching multiple terminals at the same time.

When the chip 100 touches the contact pin block 91 mounted in the cartridge mounting zone 90, the contact zone of each terminal presses against a bulging surface of the first segment of each contact pin (in the -Z axis), with the bulging surface (in the -Z axis) as an inclined surface is designed so that the mutual effective force when a chip terminal comes into contact with a printer-side contact pin is then minimized without surface contact and without pressing on the contact pin. This protects the contact pin block from damage or injury.

It can be further configured that the second plate 2 also has a third hole 23 and a fourth hole 24 (analogous to the stop part 312 in the first embodiment). is trained.

It can be further configured that an escape hole (not shown) is also provided, with which an escape from the storage unit 4a mounted in the first plate 1 or from the electrical component is possible. Depending on requirements, a storage unit 4a or an electrical component can also be mounted in the second plate 2.

In the X-axis, the first plate 1 and the second plate 2 are spaced differently from the contact pin block 91, so that there is a certain distance in the In the case of the mounted terminals in the first plate 1, the deformation extents of the corresponding contact pins on the printer side in the in the third pages 103 of the first plate 1 project.

It can be further configured that the second plate 2 is provided with at least one dent 22, which is formed in the third surface 203 continuously between the first surface 201 and the second surface 202. Specifically, the dent 22 is located between the clock terminal 211 and the power supply terminal 212 and / or between the power supply terminal 212 and the ground terminal 213. The clock terminal 211 is on the -Y axis of the dent 22, while the power supply terminal 212 is on the + Y-axis of dent 22 is standing. Alternatively, the power supply terminal 212 can be on the -Y axis of the dent 22, and the ground terminal 213 on the +Y axis of the dent 22. Thanks to the dent 22, it is possible to avoid the contact pins when installing the color cartridge 10. In this way, the contact pins can be protected from possible crushing or injury and correct positioning can also be achieved. With the arranged dent 22 between the clock terminal 211 and the power supply terminal 212 and / or between the power supply terminal 212 and the ground terminal 213, it is then possible to avoid that the foreign bodies or friction residues accumulating or adhering to the clock terminal 211, power supply terminal 212 or ground terminal 213 fall on the contact zone other terminal may fall off, which can lead to a short circuit. It can further be designed that the second plate 2 is provided with a dent 22, which is formed in the third surface 203 continuously between the first surface 201 and the second surface 202. Specifically, the dent 22 is located between the power supply terminal 212 and the ground terminal 213. Alternatively, the power supply terminal 212 can be on the -Y axis of the dent 22, and the ground terminal 213 can be on the +Y axis of the dent 22.

Referring to an eighteenth embodiment

73 shows a chip view with reference to the eighteenth embodiment according to the invention, 74 shows a schematic representation regarding the contact of the chip with the contact pins with reference to the eighteenth embodiment according to the invention. The eighteenth embodiment is based on the seventeenth embodiment and is different from that in that the second plate 2 lies behind the first plate 1 in the X axis (see 73 and 74 ). Specifically, the third side 103 of the first plate 1 lies on the +X axis side of the third surface 203 of the second plate 2, while the dent is located at least partially on the -X axis side of the clamps placed in the first plate. In the present embodiment, the contact pin block 91 contacts each terminal and, when mounting the ink cartridge 10 in the cartridge mounting zone 90, the contact pins 91a electrically connect to the portions of the terminals placed in the second side 102 and the second surface 202, i.e. in the second side 102 and the second surface 202 are the contact zones of the terminals.

With reference to 73 the second plate 2 is provided with three dents, namely a first dent 22a, a second dent 22b and a third dent 22c, each recess in the third surface 203 being formed continuously between the first surface 201 and the second surface 202. Specifically, the first dent 22a lies between the fifth surface 205 and the clock terminal 211, and the second dent 22b lies between the clock terminal 211 and the power supply terminal 212, and the third dent 22c lies between the power supply terminal 212 and the ground terminal 213. The fifth surface 205 lies on the -Y axis of the first dent 22a, while the clock terminal 211 is on the +Y axis of the first dent 22a. The clock terminal 211 is on the -Y axis side of the second dent 22b, while the power supply terminal 212 is on the +Y axis side of the second dent 22b. The power supply terminal 212 is on the -Y axis side of the third dent 22c, while the ground terminal 213 is on the +Y axis side of the third dent 22c. Thanks to the recess, it is possible to avoid the contact pins when installing the color cartridge 10. In this way, the contact pins can be protected from possible crushing or injury and correct positioning can also be achieved. With the arranged recesses between the clock terminal 211 and the power supply terminal 212 and/or between the power supply terminal 212 and the ground terminal 213, it is then avoidable that the foreign bodies or friction residues accumulating or adhering to the clock terminal 211, power supply terminal 212 or ground terminal 213 fall onto the contact zone of another terminal, which can lead to a short circuit.

75 shows a schematic representation with reference to the eighteenth embodiment according to the invention, 76 shows a schematic representation in relation to the positional relationship of the currently mounted chip with the contact pins, 77 shows a schematic representation in relation to the positional relationship of the fully assembled chip with the contact pins. When mounting the ink cartridge 10 along the -Z axis into the cartridge mounting zone 90, the terminals of the chip 100 will electrically connect to the contact pins 91a in the contact pin block 91. How out 75 As can be seen, the chip 100 lies before mounting on the +Z axis of the first segment of all contact pins 91a. When projected onto the X and Z planes along the Y axis, there is no overlap area between the chip 100 and the pin block 91. In 76 1, the positional relationship between the chip 100 and the contact pins 91a when mounting the ink cartridge 10 into the cartridge mounting zone 90 is shown along the -Z axis. During assembly, multiple recesses formed in the second plate 2 of the chip 100 can eliminate interference between the second contact pin 912 and the first segment of the fourth contact pin 914. When projecting onto the wherein the chip 100 can be positioned in the recess width range (Y-axis) relative to the contact pins 91a in order to establish correct electrical connections between the terminals of the chip 100 and the contact pins 91a. In 77 the positional relationship between the fully assembled chip 100 and the contact pins 91a during the further assembly process of the color cartridge 10 into the cartridge assembly zone 90 is shown along the -Z axis. When the chip 10 touches the contact pin block 91 mounted in the cartridge mounting zone 90, the contact zone of each terminal presses against a bulge surface of the first segment of each contact pin (in the -Z axis), with the bulge surface (in the -Z axis) as an inclined surface is designed so that the mutual effective force when a chip terminal comes into contact with a printer-side contact pin is then minimized without surface contact and without pressing on the contact pin. This protects the contact pin block from damage or injury. In comparison to the case where the contact zones of the terminals are respectively placed in the first side 101 or the third side 103 and the first surface 201 or the third surface 203, in the present embodiment the contact zones are respectively in the second side 102 and the second Surface 202 placed contact zones of the terminals so that the contact pins 91a do not pass through the first side and third side of the first plate 1 and the second surface and third surface of the second plate when inserting or removing the ink cartridge 10 into or from the cartridge mounting zone 91 2 be affected. This reduces the contact area of the chip 100 with the contact pin block 91 when inserting or removing the color cartridge 10 into or from the cartridge mounting zone 91 and thus the terminals of the chip 100 and the contact pins 91a are protected against possible damage.

78 shows a view of the chip holder with reference to the eighteenth embodiment according to the invention, 79 shows a view of the chip attached to the chip holder with reference to the eighteenth embodiment of the invention, 80 shows a schematic representation relating to the attachment of the combination of the chip with the chip holder in the color cartridge with reference to the eighteenth embodiment of the invention. In 78 and 79 A chipset is shown, which includes a chip 100 and a chip holder 5b according to the previous embodiments. The chip holder 5b serves to fix the first plate 1 and the second plate 2 and also has a holder body 51, a first column 52, a second column 53, a third column 54, a fourth column 55, a fifth column 56 and a sixth column 57 (analogous to the stop pin 414 in the first embodiment). It can be further configured that the holder body 51 is formed with a gap 511 with which the flexible connecting piece 3a remains escapeable. The first column 52, second column 53, third column 54, fourth column 55, fifth column 56 and sixth column 57 are each connected to the holder body 51. The first column 52, the second column 53, the third column 54 and the fourth column 55 are complementary to the first hole 12 and second hole 13 in the first plate 1 and to the third hole 23 and fourth hole 24 in the second plate 2 is designed so that the first plate 1 and the second plate 2 of the chip 100 are fixed to the chip holder 5b in an unrestricted manner such as snap locking, press fitting or heat welding. The fifth column 56 and sixth column 57 are each complementary to the fifth hole (not shown) and the sixth hole 502 in the cartridge body placed so that the combination of the chip 100 with the chip holder 5b can be attached to the cartridge housing, without the possibility of detaching the combination from the color cartridge. It can be further configured that the chip holder 5b is further formed with a through hole (not shown) so that the memory unit 4a and the electrical components of the chip can be accommodated.

How 79 shows, the first plate 1 is located with the substrate fully assembled on the chip holder 5b along the Z-axis on the +Z-axis side of the second plate 2. In the Z-axis there is preferably a certain distance between the first plate 1 and the second plate 2 There is a distance to which the arrangements of the contact pins within the cartridge mounting zone 90 correspond. Since the clamps are placed partly in the first plate and partly in the second plate and there are also certain distances between the clamps in the first plate and the clamps in the second plate, when mounting the ink cartridge in the cartridge mounting zone 90, even if the ink cartridge is mounted out of position, not susceptible to short circuits due to any contact pin 91a placed in the cartridge mounting zone touching multiple terminals at the same time. The third side 103 of the first plate 1 is located in the Along the mounting direction (-Z axis) of the chip 100 to a printer, the terminals placed in the second board are forward (on the -X axis side) of the terminals installed in the first board. In this way, any possible pressing of the terminals in the second plate against the contact pins 91a during assembly can be avoided in order to protect the chip terminals and/or the contact pins from damage. In concrete terms, this is beneficial for protection against possible interference between the terminals placed in the second plate and the second contact pin 912 as well as the first segment of the fourth contact pin 914 when inserting or removing the ink cartridge 10 in or out of the cartridge mounting zone 91. which may result in damage to the terminals of the chip 100 and the contact pins 91a.

In 80 a color cartridge 10 according to the invention is shown, which has a chip 100, a clamping handle 30, an ink outlet 40 and a cartridge body 50. The cartridge body 50 is formed with a receiving chamber 503 located in the Z axis between the clamping handle 30 and the ink outlet 40 to accommodate the mounted chip 100. In the present embodiment, the fifth bore (not illustrated) and the sixth bore 502 are located on the two sides of the receiving chamber 503 and expediently cooperate with the chip holder 5b in order to fix the combination of the chip 100 with the chip holder 5b to the cartridge housing, without the possibility of removing the combination from the color cartridge.

In the present embodiment, the first plate 1 and the second plate 2 are attached to the chip holder 5b and thus installed together with the chip holder 5b as a whole in the receiving chamber 503. In further embodiments, the first plate 1 and second plate 2 can be installed directly into the receiving chamber without a chip holder, for example the chip 100 is provided with an attachment which fits together with the attachment of the cartridge body 50. Specifically, a groove or bulge formed in the chip 100 can be connected in a snap-like manner to a bulge or groove formed in the cartridge body 50.

Referring to a nineteenth embodiment

How out 81 until 83 As can be seen, the chip 100 in the present embodiment comprises a substrate 110, which has an overlapping outer plate 111 (analogous to substrate 310 in the first embodiment) and an inner plate 112 (analogous to the second component or the conductive element 500 in the first embodiment). . On the +X side of the inner plate 112 lies the outer plate 111, the end face of which acts in the +X direction as a first external connection surface 113 (analogous to the front surface 310a in the first embodiment) and the end face of which acts in the -X direction as the inner connection surface 114 (analogous to the rear surface 310b in the first embodiment). In the first external connection surface 113 are the first terminal 130b (analogous to first terminal 360 in the first embodiment), the second terminal 130c (analogous to second terminal 370 in the first embodiment), the third terminal 140 (analogous to third terminal 380 in the first embodiment) and the fourth terminal 150 (analogous to fourth terminal 390 in the first embodiment) are excellently installed along the -Y side. In the +Y side of the outer plate 111, the gap 115 (analogous to the gap 311 in the first embodiment) is formed. A memory unit 170 is installed in the inner pad 114 and is electrically connected to the first terminal 130b, second terminal 130c, third terminal 140 and fourth terminal 150. The +X-side end face of the inner plate 112 adheres as a second outer connection surface 116 (analogous to the surface on the +X-axis side of the second component component or the guide element 500 in the first embodiment) to the inner connection surface 114 partially. In the overlap area between the second external connection surface 116 and the gap 115, a fifth terminal 160 (equivalent to epitaxial part 530 as in the first embodiment) is excellently installed, the +X-side end face of which lies on the -X side of the first external connection surface 113. The local inner plate 112 (analogous to the second component or the conductive element 500 in the first embodiment) can be viewed as a component of the chip 100.

In the overlap area between the second outer connection surface 116 and the inner connection surface 114, a connection terminal 180 that is electrically connected to the fifth terminal 160 is installed, while an inner terminal (not shown, analogous to the inner terminal 330 in the first embodiment) that can be connected to this connection terminal 180 is placed in the inner connection surface 114 is. The inner terminal is electrically connected to the storage unit 170 so that the fifth terminal 160 electrically connects to the storage unit 170 via the connection terminal 180 and the inner terminal.

Since the first terminal 130b to the fourth terminal 150 are all installed in the first external connection surface 113 and also the +X-side end face of the fifth terminal 160 lies on the -X side of the first external connection surface 113, the contact zones remain from the first terminal 130b up to the fourth terminal 150 is not on the same level with the contact zone of the fifth terminal 160. In the assembled state, compared to a chip with a single substrate, an advantage is that the contact pins corresponding to the first terminal 130b to the fourth terminal 150 have a larger deformation range, so that a stronger friction force is available in the Y direction . The gap 115 can cooperate with the contact pin corresponding to the fifth terminal 160 to limit the -Yward displacement of the chip 100 and thus prevent the +Yward displacement of the entire ink cartridge.

Although the connection line of the contact zones of the first terminal 130b and the fourth terminal 150 is parallel to the connection line of the contact zones of the second terminal 130c and the third terminal 140, the deformation amount of the contact pin corresponding to the fifth terminal 160 is smaller than any deformation amount of the contact pin contact pins corresponding to the remaining four terminals, so that the contact zone of the fifth terminal 160 is not in the same straight line with the contact zones of the second terminal 130c and the third terminal 140. Therefore, the fifth terminal 160, the second terminal 130c and the third terminal 140 cannot be considered to be arranged in a row.

In the overlap area between the inner plate 112 and the storage unit 170, an alternative field 117 is provided, accordingly there is a first alignment hole 118 (analogous to the stop part 312 in the first embodiment) in the outer plate 111, and a second alignment hole 119 in one that is complementary to the first alignment hole 118 Area of the inner plate 112 is provided. Thanks to the alternative field 117 and the two alignment holes, the fit between the outer plate 111 and the inner plate 112 can be strengthened and an aligned assembly of the outer plate 111 with the inner plate 112 or the precise assembly of the ink cartridge can be ensured.

In 84 until 86 A further embodiment is shown, which remains differentiated from the previous embodiment in that the gap 115 is formed in the -Y side of the outer plate 111 and the first clamp 130b is placed in the inner plate 112, while the second clamp 130c to the fifth Terminal 160 is all installed in the outer plate 111. The second terminal 130c to the fifth terminal 160 are electrically connected to the storage unit 170. The first terminal 130b is electrically connected to the storage unit 170 via the connection terminal 180 and the inner terminal. The outer plate 111 is provided with a first alignment hole 118, while the inner plate 112 is formed without an alignment hole. Since the deformation amount of the contact pin corresponding to the first terminal 130b is smaller than each deformation amount of the contact pins corresponding to the remaining four terminals, the first terminal 130b and the second terminal 130c cannot be considered to be arranged in a row because a non-parallel heterogonal relationship between the contact zone connection line of the first terminal 130b to the second terminal 130c and the imaginary line L3 and the Y axis, although the contact zones are from the second terminal 130c, third terminal 130c and fifth terminal 160
all located in an imaginary line L3 parallel to the Y axis.

Referring to a twentieth embodiment

In 87 and 88 A view of the chip 100 from a first perspective and a view from a second perspective are shown according to the present embodiment. As can be seen, the chip 100 includes a substrate as a flexible curved surface substrate 210, which is conveniently supported by the chip holder 300a is supported to maintain the crooked state and can also be installed in the color cartridge with the help of the chip holder 300a. The surface of the curved surface substrate 210 facing away from the chip holder 300a acts as an external connection surface 211a, which in the -Y side has a first terminal 220a, a second terminal 230, a third terminal 240 and a fourth terminal 250, and in the +Y- Side is formed with a fifth clamp 260, wherein the first clamp 220a and the fourth clamp 250 are at least partially placed in the +Z sides of the second clamp 230 and the third clamp 240.

In the present embodiment, the external connection surface 211a is designed as a cylindrical surface. The dashed line S in 88 indicates an axis direction of the external connection surface 211a. Since the projection of the dashed line S onto the Y and Z planes intersects with the Y axis, the mating of the contact pins with the curved surface substrate can result in limiting the offsets of the chip 100 in the Y direction. Specifically, frictional forces intended to overcome the displacements of the ink cartridge in the Y direction increase with the increase in the deformation amount of the corresponding contact pin so as to limit the displacements of the ink cartridge in the Y direction.

Since the external connection surface 211a is designed here as a curved surface and there are different deformation extents for the contact pins corresponding to the five mentioned terminals in the contact pin block 91, the contact zones of the second terminal 230, third terminal 240 and fifth terminal 260 (have shaded areas corresponding to the terminals). on the contact zones) are not in the same plane, and the projections of the contact zones of these terminals (230, 240, 260) on the Y and Z planes are not in the same straight line. In that case, these three terminals cannot be considered as being arranged in a row. Furthermore, the first terminal 220a and fourth terminal 250 cannot be considered to be arranged in a row because the contact zone connection line from the two terminals does not remain parallel to the Y axis.

Referring to a twenty-first embodiment

Regarding 89 The chip 400a includes a substrate 410a and a set of terminals placed in the substrate 410a, the substrate 410a having a smooth front surface 411a as the largest external surface in the substrate 410a. A recess is formed in the front surface 411a. The clamp set includes five spaced clamps, of which at least one clamp functions as a flat clamp 420 placed in the front surface 411a, and further at least one clamp functions as a countersunk clamp 430 placed in the recess. The recess includes a dent flank 413a that intersects with the front surface 411a and the Y-axis and a dent bottom surface 414a facing away from the front surface 411a. Accordingly, the countersunk clamp 430 can be installed either in the dent flank 413a or in the dent bottom surface 414a.

Here, the clamp set includes three flat clamps 420 and two countersunk clamps 430, while a first recess 412a and a second recess 412b are formed at a distance in the front surface 411a. A first sinking clamp 430a corresponding to the second terminal 232 of the chip 20 is installed in the dent bottom surface 414a of the first recess 412a, while a second sinking clamp 430b corresponding to the fourth terminal 234 of the chip 20 is installed in the second recess 412b
is placed in the dent floor area. The three flat terminals 420 include a first flat terminal 420a corresponding to the first terminal 231 of the chip 20, a second flat terminal 420b corresponding to the third terminal 233 and a third flat terminal 420c corresponding to the fifth terminal 235. The contact zones of the second flat clamp 420b and the third flat clamp 420c are located in an imaginary line L4 parallel to the Y axis, but the projection of the contact zone of the first flat clamp 430a onto the Y and Z planes does not fall in the Y plane. and Z plane, where the imaginary line L4 projects. In that case, these three terminals cannot be considered as being arranged in a row. The contact zone connection line between the first flat terminal 420a and the second flat terminal 430b projects on the Y and Z planes not parallel to the Y axis and further lies in a heterogonal relationship relative to the imaginary line L4. In that case, these two terminals cannot be considered as being arranged in a row.

The dent is provided with a dent flank that overlaps the Y-axis, which can limit any displacement of the chip 400a relative to the corresponding contact pin in the Y-axis and thus prevent any displacement of the entire ink cartridge in the Y-direction in the installed position.

The chip 100 includes a first hole 121 and a second hole 122 (analogous to stop part 312 in the first embodiment). The first bore 121 and the second bore 122 are all formed as a through hole in the substrate 120, or continuously between the front surface 120a and the rear surface of the substrate 120. The first bore 121 is formed as a dent from the left flank 120c to the right flank 120d, while the second bore 122 is formed as a dent from the right flank 120d to the left flank 120c. The chip 100 can then be fixed in the ink cartridge 10 through the first hole 121 and/or the second hole 122. Typically, the stop pin formed in the cartridge body (analogous to stop pin 414 in the first embodiment) mates with the first bore 121 and the second bore 122 in a prominent manner. The chip 100 is then welded to the cartridge body using a thermal welding head.

Regarding 90 and 91 the chip further comprises bulges (analogous to the second component or the conductive element 500 in the first embodiment). In the present embodiment, a bulge 141 (analogous to the second component or the guide element 500 in the first embodiment) is provided, which is placed in the front surface 120a of the substrate 120. In the front surface 120a of the substrate 120, all of the first clamp 131, third clamp 133, fourth clamp 134 and fifth clamp 135 are installed, while the second clamp 132 is placed in the first bump 141. In the present embodiment, the first bulge 141 is closer to the surface 120e of the substrate 120 relative to the first clamp 131 and also the front surface 120a of the substrate 120 extends in the +X axis with a as a first tip 141a defined +X-axis side end, wherein the first tip 141a is not in the same Y and Z plane with the substrate 120.

Alternatively, the second clamp 132 may be placed anywhere in the outer surface of the first bulge 141, for example in +Y-axis side surface, -Y-axis side surface, +Z-axis side surface, -Z-axis side surface, or at the first tip 141a or on the overlapping edge of the individual surfaces. The first bulge 141 can be a part of the guide element, and the second clamp 132 can be a part of the first bulge 141.

How out 91 As can be seen, the second terminal 132 is preferably placed on the first tip 141a, while the remaining terminals are installed in the substrate 120, so that the contact zone of the second terminal 132 and the contact zones of the other terminals lie in different Y and Z planes.

92 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the twenty-second embodiment according to the invention When installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90 (see 92 ), the first tip 141a of the first bulge 141 of the chip 100 inserts itself into a second narrow gap 982 in order to contact the second contact pin 912 and thus create an electrical connection between the second terminal 132 and the second contact pin 912. As a result, short circuits on the chip 100 can be excluded and the durability of the chip can be ensured by having the contact zone on the first tip 141a of the second terminal 132 in a different Y and Z plane than that of the contact zones of the other terminals (first terminal 131 , third terminal 133, fourth terminal 134 and fifth terminal 135) in the substrate 120 lies in the same Y and Z plane. If a liquid adheres to the terminals placed in the substrate 120, for example to the first terminal 131, the liquid remains very difficult to penetrate to the second terminal 132, or the flowing liquid becomes at the connection area between the bulge 141 and the front surface 120a of the substrate 120 stop because the second clamp 132 is attached to the first tip 141a of the first bulge 141 and is therefore not placed in a same Y and Z plane with the substrate 120.

It is also conceivable that the second terminal 132 of the chip 100 is arranged with a contact with the second contact pin 912 in the finished assembled state. For this purpose, the second clamp 132 can be installed either on the first tip 141a of the first bulge 141 or in a -Z-axis-side surface of the first bulge 141.

It should be noted that the substrate 120 may be provided with unlimited number and shape of bulges, for example with one or more bulges whose shapes may be conical, triangular and/or rectangular. Any terminal from the first terminal 131 to the fifth terminal 135 may be installed in each bulge, provided that an electrical connection can be established between the terminal installed in the bulge and a corresponding contact pin. For example, the first bulge 141 can be arranged with a contact option for the second contact pin 912 in the finished assembled state, or with a contact option for the others in the first bulge 141 ted contact pins. Furthermore, the first terminal 131 can be mounted, for example, in the first bulge 141, with an electrical connection option between the first bulge 141 and the first contact pin 911 being present.

Referring to a twenty-third embodiment

93-94 each show a view of the chip with reference to the twenty-third embodiment according to the invention. The present embodiment differs from the twenty-second embodiment in that the substrate 120 is formed with several bulges, for example with a first bulge 141, a second bulge 142, a third bulge 143, a fourth bulge 144 and a fifth bulge 145, with the first clamp 131 to the second tip 142a of the second bulge 142, the second clamp 132 to the first tip 141a of the first bulge 141, and the third clamp 133 to the fifth clamp 135 each in the third bulge 143 to the fifth bulge 145 to be installed.

How out 93 and 94 As can be seen, the first bulge 141, the second bulge 142, the third bulge 143, the fourth bulge 144 and the fifth bulge 145 are laid out sequentially along the +Y axis of the substrate 120.

95 1 shows a schematic diagram relating to contact between the chip and a contact pin with respect to the twenty-third embodiment of the present invention. When mounting the color cartridge 10 together with the mounted chip 100 according to the present embodiment (see 95 ) in the cartridge mounting zone 90, the second tip 142a of the second bulge 142 of the chip 100 is inserted into the first narrow gap 981 and thus contacts the first vertical segment 911k of the first contact pin 911, so that the first terminal 131 electrically connects to the first contact pin 911 . The first tip 141a of the first bulge 141 of the chip 100 as well as the third tip 143a of the third bulge 143, the fourth tip 144a of the fourth bulge 144 and the fifth tip 145a of the fifth bulge 145 are each inserted into the second narrow gap 982, the third Narrow gap 983, the fourth narrow gap 984 and the fifth narrow gap 985 and therefore each contact the second contact pin 912, the third contact pin 913, the fourth contact pin 914 and the fifth contact pin 915, so that the second terminal 132 is connected to the second contact pin 912, which electrically connect the third terminal 133 to the third contact pin 913, the fourth terminal 134 to the fourth contact pin 914 and the fifth terminal 135 to the fifth contact pin 915. How out 94 As can be seen, the contact zone of the individual terminals (the first terminal 131 to the fifth terminal 135) are located in different bulging surfaces which are not connected to one another. As a result, possible short circuits on the chip 100 can be excluded by the contact zones of the individual terminals not being connected to one another, so that it may be very difficult for liquid adhering to one terminal to penetrate into another terminal, or for the flowing liquid to reach the connection area between the bulge and the front surface 120a of the substrate 120 remain. For example, it is very difficult for a liquid adhering to the first clamp 131 on the second tip 142a of the second bulge 142 to penetrate the third clamp 133 on the third tip 143a of the third bulge 143. This makes it possible to exclude short circuits between the first terminal 131 and the third terminal 133 and thus ensure the durability of the chip 100.

In the present embodiment, the chip 100 may be formed with one or more of the bulges (the first bulge 141 to the fifth bulge 145). For example, the chip 100 may be provided with a second bulge 142 and a third bulge 143, where a first terminal 131 and a third terminal 133 are installed, respectively, while the other terminals such as the second terminal 132, fourth terminal 134 and fifth terminal 135 are always are still placed in the front surface 120a of the substrate 120 of the chip.

Alternatively, all bulges in the chip 100 can be arranged to overlap with the Z-axis, or laid out in several rows along the Z-axis.

Alternatively, the second clamp 132 may be placed anywhere in the outer surface of the first bulge 141, for example in +Y-axis side surface, -Y-axis side surface, +Z-axis side surface, -Z-axis side surface, or at the tip 141a or on overlapped edge of the individual surfaces. The other clamps can also be placed anywhere on the outer surface of a bulge.

In the fully assembled state, each terminal can still be arranged in the third segment of a corresponding contact pin for contact with the horizontal area. For example, the first terminal 131 of the chip 100 can also be arranged to make contact with the first contact pin 911. For this purpose, the first clamp 131 can be attached to the tip 142a of the second bulge 142 or in a -Z- Install axle side surface of first bulge 142.

Referring to a twenty-fourth embodiment

How out 96 As can be seen, the ink cartridge 10 according to the invention comprises a cartridge body 50, which is designed as a cube with several sides, the end face running in the plumb direction being there as a bottom 110a with a formed ink outlet 40, while the front 107 and the back (not shown ) stand against each other and also remain perpendicular to the underside 110a. A clamping handle 30 is attached to the upper region of the front 107, the lower region of which is formed with a receiving point 106a. The receiving point 106a serves to receive the mounted chip 20 (as shown in 97 ) and the separate electrical connector 80 (as shown in 98 , analogous to the second component or guide element 500 in the first embodiment). The fifth terminal 205 (analogous to the epitaxial part 530 in the first embodiment) is placed in the electrical connection piece 80 and is connected to a contact pin block 91 on the printer side. The chip 20 includes a substrate 120, in the surface facing away from the cartridge body 50, a plurality of terminals are installed, with the first terminal 201a and the fourth terminal 204a in the first row and the second terminal 202a and the third terminal 203a in the second row . The contact zones of the first terminal 201a, the second terminal 202a, the third terminal 203a, and the fourth terminal 204a are not projected onto the assembly direction.

The first terminal 201a to the fourth terminal 204a are each represented as a data terminal, clock terminal, power supply terminal and reset terminal, while in the electrical connector 80 the fifth terminal 205a is placed as a ground terminal, which is used to include a ground potential and via a to a printer-side contact pin connectable contact zone. The contact zones of the first terminal 201a, the second terminal 202a, the third terminal 203a, the fourth terminal 204a and the fifth terminal 205a each mate with a corresponding contact pin in the contact pin block 91.

The electrical connector 80 can be designed in any shape such as cubic, cylindrical, provided that a smooth installation of the electrical connector 80 can take place in a specific contact zone. The electrical connector 80 may connect to the receiving site 106a in a manner such as gluing and snapping. Thereafter, the chip 20 is installed and fixed in the receiving location 106a by means of the fit of the recess (analogous to the stop part 312 in the first embodiment) with the bulge (analogous to the stop pin 414 in the first embodiment) or by means of an adhesive process to bring about an insulated connection between the substrate 120 and the electrical connector 80 as well as a complementary fit with the contact pin block 91.

It is understandable that there can be a certain spatial distance between the substrate 120 of the chip 20 and the electrical connection piece 80 (without the possibility of contact), or a certain clearance or a certain difference height (contactless and also not connectable). If there is a certain difference in height, there is a non-flushness in the end piece of the rear surface pointing towards the front surface 107, which corresponds to different deformation extents of the individual contact pins in the fully assembled state, provided that there is connectivity to the contact pin block 91. For example, the substrate 120 and the electrical connector 80 can each be installed separately into the receiving location 106a. The substrate 120 and the electrical connector 80 can be placed perpendicularly, parallelly or inclined to one another, provided that an insulated connection between the two and a complementary mating with the printer-side contact pin block 91 are achieved.

In a further embodiment, the receiving point 106a is further provided with a conductor element (not shown), which electrically connects the electrical connection piece 80 to the chip. A fifth terminal 205a is installed in the electrical connection piece 80, which electrically connects via this conductor element to the wafer attached to the back of the chip 20 (side of the substrate 120 pointing towards the cartridge body 50) (in the first embodiment, the inner terminal 330 is included). electrically connected to the wafer, inner terminal, conductor element and electrical connector 80). In addition, the chip 20 is placed in the receiving location 106a, in the substrate 120 of which the first terminal 201a, the second terminal 202a, the third terminal 203a and the fourth terminal 204a are installed. The layouts of the terminals in the chip 20 and the terminals in the electrical connector 80 are intended to achieve complementary mating with the printer-side contact pin block 91.

Referring to a twenty-fifth embodiment

In 99 According to the invention, a twenty-fifth embodiment is shown, in which the color cartridge is arranged essentially analogously to the twenty-fourth embodiment and, however, the only difference is that the chip 20 and the electrical connection piece 80 are installed in the chip holder 70 as the receiving point 106a. In the present embodiment, the color cartridge 10 comprises a cartridge body 50, on the upper area of the front 107 a clamping handle 30 is attached and on the lower area a chip holder 70 (here non-conductive chip holder 70) is attached. How out 99 As can be seen, the chip holder 70 is provided with an electrical connector 80 in which the fifth terminal 205a is installed, while the first terminal 201a, second terminal 202a, third terminal 203a, fourth terminal 204a are placed in the substrate 120. When mounting the chip 20 into the chip holder 70, the electrical connector 80 can be adhered to the chip 20 together. It is understandable that the electrical connection piece 80 can be designed in any profile, with the substrate 120 and the electrical connection piece 80 each being fixed separately in the chip holder 70, with a mutually insulated connection between the two in order to prevent the possibility of short circuiting between the terminals in the substrate 120 and the fifth terminal 205a in the electrical connector 80. It is still understandable that there can be a certain spatial distance between the substrate 120 and the electrical connection piece 80 (without the possibility of contact), or a certain clearance or a certain difference height (contactless and also not connectable). For example, the substrate 120 and the electrical connector 80 can each be installed separately into the chip holder 70. The substrate 120 and the electrical connector 80 can be placed perpendicularly, parallelly or inclined to one another, provided that an insulated connection between the two and a complementary mating with the printer-side contact pin block 91 are achieved. Thereafter, the chip holder 70, the chip 20 and the electrical connector 80 can be installed into the cartridge body 50 as a combination, forming the color cartridge 10 as a complex.

In a further embodiment, the chip holder 70 is designed to be conductive, in which the electrical connector 80 and the chip 20 are installed. The fifth terminal 205a is then electrically connected to the chip 20 with the conductive chip holder 70. The layouts of the terminals in the chip 20 and the terminals in the electrical connector 80 are of course intended to achieve complementary mating with the printer-side contact pin block 91.

Referring to a twenty-sixth embodiment

Regarding 100 The receiving point 106a can be formed in one piece in the front 107 of the cartridge body 50 or replaced by a chip holder. In the present embodiment, a chip holder acts as the receiving point 106a, on which as shown in 104 a conductive member 108 (analogous to the conductive member in the twenty-fourth embodiment) is attached to electrically connect the electrical connector 109 installed therein (analogous to the second component or the conductive member 500 in the first embodiment) to the chip 20 installed therein.

How 101 until 103 show, the chip 20 comprises a plate-shaped substrate 120, the outer surface of which, occupying the largest area, is designed as a first external connection surface 102a (analogous to the front surface 301a in the first embodiment), opposite which a first back connection surface 103a (with reference to 102 , analogous to the rear surface 301b in the first embodiment). A plurality of terminals are installed in the first outer connection surface 102a, while a wafer 104a and a first contact 207 connected to this wafer (analogous to the inner terminal 330 in the first embodiment) are mounted in the first back connection surface 103a. The electrical connection piece 109 comprises an electrical conduction plate 113a (analogous to the second component or the conduction element 500 as in the first embodiment) with a plate-shaped profile, the surface of which covers the largest area is designed as a second outer connection surface 111b, opposite which a second back connection surface 112b lies. An external terminal (the first terminal 201a in the present embodiment) is installed in the second external connection surface 111, while in the second back connection surface 112b a second contact 206a corresponding to this external terminal is attached, which is connected to the first contact 207 together via the guide element 108 a wafer 104a is electrically connected,

Several terminals are installed in the first external connection surface 102a of the substrate 120, with an external terminal (analogous to epitaxial part 530 in the first embodiment) being placed in the second external connection surface 111b of the electrical connection piece 109, which is either the first terminal 201a or as the second terminal 202a, third terminal 203a or fourth Terminal 204a can serve. Except for the terminal placed in the second external connection surface 111b, all other terminals are installed together with the fifth terminal 205a in the first external connection surface 102a. In the present embodiment, an example is that an external terminal is installed as the first terminal 201a in the electrical connector 109, while the second terminal 202a to the fifth terminal 205a are placed in the substrate 120 or in the first external connection surface 102a .

In the present embodiment, the electrical conductive plate 113a is formed as a long rectangular structure, while the electrical connector 109 can be profiled in any way such as a prism or cylinder, provided that in the second external connection surface 111b of the electrical conductive plate 113a the contact pins 901 corresponding connectable terminals can be installed.

How out 104 As can be seen, the substrate and the electrical connection piece 109 of the chip 20 are installed in the receiving location 106a in such a way that the second contact 206a of the electrical connection piece 109 rests in a form-fitting manner on the first contact 207 of the substrate 120, the wafer 104a and the conductive element 108. The chip 20 can be fixed in the manner of fitting the recess with the bulge in the receiving location 106a, or by means of an adhesive method, with a successful assembly state as shown in 105 looks.

It is understandable that there can be a certain spatial distance or certain play or a certain difference height between the substrate 120 and the electrical connection piece 109. If there is a certain difference in height, there is a non-flushness in the end piece of the rear surface pointing towards the front surface 107, which corresponds to different deformation extents of the individual contact pins in the fully assembled state, provided that there is connectivity to the contact pin block 901. For example, the substrate 120 and the electrical connector 109 can each be installed separately in the receiving location 106a. The substrate 120 and the electrical connector 109 can be placed perpendicularly, parallelly or overlapped with one another, provided that an insulated terminal connection between the two and complementary mating with the printer-side contact pin block 901 are achieved.

Here, the first terminal 201a is installed separately in the second external connection surface 111b of the electrical connection piece 109, with the second contact 206a of the electrical connection piece 109 being connected via the conductive element 108 to the first contact 207 of the substrate 120 and to the wafer 104a. This can minimize the possibility of shorting to other terminals and maintain the safety of the chip 20 and the printer.

Referring to a twenty-seventh embodiment

In 106 According to the invention, a twenty-seventh embodiment is shown, in which the color cartridge 10 is arranged essentially analogously to the twenty-sixth embodiment and, however, the only difference is that the receiving point 106a is integrated in the cartridge body 50.

How out 106 As can be seen, the receiving point 106a is provided with a guide element 108. When mounting the chip 20 in the receiving location 106a, the second contact 206a of the electrical connector 109 will rest in a form-fitting manner against the first contact 207 of the substrate 120, the wafer 104a and the conductive element 108. It is understandable that the electrical connector 109 can be profiled as desired, with the chip 20 and the electrical connector 109 each being installed independently in the receiving point 106a, all connected to the guide element 108.

A plurality of terminals are installed in the first external connection surface 102a of the substrate 120, i.e. a second terminal 202a, a third terminal 203a and a fourth terminal 204a, while the first terminal 201a is placed in the electrical connection piece 109. In the finished assembly state, the complete terminal layout starting from the wherein the first terminal 201a, the second terminal 202a, the third terminal 203a and the fourth terminal 204a are not projected overly onto the mounting direction, so that the contact zones are each of the first terminal 201a, the second terminal 202a, the third terminal 203a, the fourth terminal 204a, the fifth terminal 205a can fit together in a complementary manner with several contact pins 901 in the contact pin block 91.

The external terminal placed in the second external terminal surface 111b of the electrical connector 109 may be configured as either the first terminal 201a or the second terminal 202a, third terminal 203a, or fourth terminal 204a. An example of this is taken in the present embodiment.

By arranging an external terminal in the second external connection surface 111b, the possibility of short circuiting with other terminals can be minimized and the chip 20 and the printer can be secured.

Referring to a twenty-eighth embodiment

In the present embodiment, the first terminal 131, second terminal 132, third terminal 133, fourth terminal 134 and fifth terminal 135 (analogous to fifth terminal in the third embodiment) are all installed in the front surface 120a of the substrate 120. In the present embodiment, the coordinates of each of the first terminal 131, the second terminal 132, the third terminal 133, the fourth terminal 134 and the fifth terminal 135 are not identical to each other along the Y axis, while the first terminal 131 is to the fourth However, terminal 134 and the second terminal 132 to the third terminal 133 and the fifth terminal 135 in the Z axis remain the same with regard to the coordinate system, with the first terminal 131 being different from the second terminal 132 in the Z axis with regard to the coordinate system. Axis is different. The fifth clamp 135 in the front surface 120a is close to the right flank 120d, or away from the remaining four clamps.

The color cartridge 10 is provided with a chip mounting zone (analogous to the receiving point 411 in the first embodiment) for receiving the chip 100, which has a first stop pin 121a, a second stop pin 122a and a rib part 310c, the first stop pin 121a and the second stop pin 122a (analogous to stop part 312 in the first embodiment) fits together with the first hole 121 and the second hole 122 (analogous to the stop pin 414 in the first embodiment) of the chip in a prominent manner. The chip 100 is then welded to the cartridge body using a thermal welding head.

The direction along which the ink cartridge 10 is attached to a slide block of the cartridge mounting zone 90 is defined as the mounting direction P. The mounting direction P is also considered the direction along which the substrate 100 is attached to the slide block of the cartridge mounting zone 90. In the present embodiment, the mounting direction MD is considered the +Z direction. The two right-angled directionality are each defined as a first direction and a second direction. In the present embodiment, the first direction is considered a Z direction and the second direction is considered an X direction. Starting from the top, the cartridge mounting zone and the chip are viewed. The two rectangular straight lines are each defined as a first imaginary line C1 and a second imaginary line C2. The first imaginary line C1 is considered the first direction, while the second imaginary line C2 is considered the second direction. When installing the chips 100 according to the present embodiment into the ink cartridge 10, the rib portion 310c will raise the side of the chip adjacent to the fifth terminal 135 along the +X axis. When projecting all the contact zones of the terminals individually installed in the substrate, not all of the contact zones project onto the second imaginary line C2 with reference to a plan view. This can protect the chip from damage due to excessive power current and enhance the security of the chip by arranging the substrate at an a angle relative to the front face of the cartridge body and making the vertical front face of the fifth terminal 135 higher than the other terminals lies, so that the fifth contact pin 915 can contact the fifth terminal 135 prematurely or with an increased pressure force.

When mounting the color cartridge 10 together with the installed chip 100 according to the present embodiment in the cartridge mounting zone 90, the fifth terminal 135 of the chip 100 initially contacts the contact pin head in the fifth vertical segment 915k of the fifth contact pin 915 in order to establish an electrical connection of the fifth terminal 135 the fifth contact pin 915 to bring about. The remaining terminals each press against a remaining contact pin head and connect to it electrically.

Referring to a twenty-ninth embodiment

A twenty-ninth embodiment will be explained below, which remains different from the twenty-eighth embodiment as follows.

In the present embodiment, the arrangement of the rib part to fit with the cartridge mounting zone can remain or be omitted.

Regarding 107 until 109 The fifth terminal 145 (analogous to the epitaxial part 530 in the first embodiment) of the chip 100 is located on the side of the front surface 120a adjacent to an edge of the right flank 120d, specifically facing away from the front surface 120a in the +X axis from the remaining four terminals to the +X axis. In the present embodiment, the first terminal 131, second terminal 132, third terminal 133 and fourth terminal 134 are analogous to The twenty-eighth embodiment is arranged, which will not be detailed here. Regarding 109 The fifth clamp 145 is higher in the direction of the vertical front surface 120a than the other clamps. When projecting all the contact zones of the terminals individually installed in the substrate, not all of the contact zones project onto the second imaginary line C2 with reference to a plan view. When mounting the ink cartridge, the fifth vertical segment 915k of the fifth contact pin 915 will contact the fifth terminal 145 prematurely or with an increased pressure force. This can protect the chip from damage due to excessive mains current and increase the operational reliability of the chip. The fifth clamp 145 may be fixed to a conductive component (analogous to the second component or conductive element 500 in the first embodiment and like Bulge in the twenty-second embodiment) in the substrate and thus belongs to a portion of the conductive component. The conductive component presses against the back surface of the substrate, with the fifth terminal 145 electrically connecting to the wafer in the substrate in a similar way to the electrical connection between the wafer and the second terminal in the twenty-second embodiment.

110 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the present embodiment When installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90 (see 110 ) the excellent fifth terminal 145 of the chip 100 initially contacts the fifth vertical segment 915k of the fifth contact pin 915, so that the fifth terminal 135 (analogous to epitaxial part 530 in the first embodiment) electrically connects to the fifth contact pin 915. The remaining terminals each press against a remaining contact pin head and connect to it electrically.

Alternatively, at least one terminal may be prominently disposed among the first terminal 131, second terminal 132, third terminal 133 and fourth terminal 134.

Referring to a thirtieth embodiment

A thirtieth embodiment will be explained below, which differs from the twenty-eighth embodiment as follows.

How out 111 As can be seen, the excellent first clamp 151 is installed on a side of the front surface 120a adjacent to the surface 120e, i.e. facing away from the remaining clamps (the second clamp 132, the third clamp 133, the fourth clamp 134, the excellent fifth clamp 155), while the excellent fifth clamp 155 is placed on a side of the front surface 120a adjacent to an edge of the right flank 120d, i.e. facing away from the remaining four clamps. How out 113 As can be seen, the excellent first clamp 151 and the excellent fifth clamp 145 are higher in the direction of the vertical front surface 120a than the other clamps. When projecting all contact zones of the terminals individually installed in the substrate, not all contact zones project onto the second imaginary line C2. The contact of the first terminal 151 remains separate from the other terminals (the second terminal 132, third terminal 133, fourth terminal 134, fifth terminal 155), or rather far away from the other terminals. Thereby, the possibility of short-circuiting the excellent first terminal 151 with other terminals can be minimized.

Between the second terminal 132 and the third terminal 133 there is a spacer part 123a (see 112 ) is formed, but there is no restriction on its design and in the present embodiment it is there as a slot. In this way, possible contamination of the other terminals can be excluded and the durability of the chip can be ensured by placing the second terminal 132 separately from the third terminal 133, expediently in order to avoid foreign bodies that may accumulate or adhere to the excellent first terminal 151 or friction residues can detach from the substrate due to gravity from the spacer part 123a, which can lead to contamination of the other terminals. 114 shows a schematic representation in relation to contact between the chip and the contact pins with reference to the thirtieth embodiment according to the invention When installing the color cartridge 10 together with the mounted chip 100 according to the present embodiment in the cartridge mounting zone 90 (see 114 ) the tips each insert themselves from the excellent first terminal 151 and the excellent fifth terminal 155 of the chip 100 into the first narrow gap 981 and the fifth narrow gap 985 in order to respectively contact the first contact pin 911 and the fifth contact pin 915 and thus electrical connections between the excellent first terminal 151, the excellent fifth terminal 155 each with the first contact pin 911, the fifth contact pin 915. The remaining terminals each press against a remaining contact pin head and each connect to it electrically.

Alternatively, an unlimited number of the spacer parts 123a can be placed between any two terminals.

Alternatively, the second terminal 132, third terminal 133 and fourth terminal 134 may be prominently disposed with at least one prominent terminal placed in the front surface 120a. With excellent arrangement, it can be columnar bump, scaly bump.

Referring to a thirty-first embodiment

In 115 until 118 The thirty-first embodiment according to the invention is illustrated, which differs from the first embodiment in that the chip 300 comprises a substrate 310 and a second component (see 115 and 116 ), whereby the second component acts as a guide element 500 that can flexibly snap into the gap 311. The guide element 500 has an epitaxial part 530, a connecting part 510, a spring element 580, a locking lug 590 and a gap 570. The epitaxial part 530 is formed with an external contact zone 520, which acts to press against the fifth contact pin 915. The external contact zone 520 serves to include a ground potential. To mount the chip on a printer, the electrical connection path extends from the fifth contact pin 915 via the conductive element 500, the inner terminal 330 to the memory unit. The spring element 580 can, in the case of a lack of contact between the fifth contact pin 915 and the second component or the conductive element 500, or when the chip is not yet mounted on the printer, support the conductive element 500 in order to avoid continuous contact with the inner terminal 330. When contacting the fifth contact pin 915 with the second component or the conductive element 500, the conductive element 500 can touch the inner terminal 330. With such a configuration, the conductive element 500 or the second component cannot be electrically connected to the substrate 310 when it is not in operation, but can only be connected when it is in operation. In this way, incorrect mounting of the chip can be avoided and contact robustness and reliability can be ensured. The locking lug 590 serves to robustly fix the guide element 500 to the substrate 310. Thanks to the arranged gap 570, the epitaxial part 530 and the external contact zone 520 can move in the -X axis or in a direction of the front surface 310a pointing towards the rear surface 310b. In the event that there is contact between the fifth contact pin 915 and the second component or the conductive element 500, the epitaxial part 530 or the external contact zone 520 shifts in the -X axis or a direction of the front surface 310a pointing towards the rear surface 310b and thus presses the spring element 580 together, the external contact zone 520 also moving with the displacement of the baffle 500 or the second component to bring the connecting part 510 into contact with the internal clamp 330 placed in the side wall of the gap 311. In the event that there is no contact between the fifth contact pin 915 and the conductive element 500, the epitaxial part 530 moves to the front surface of the substrate 310 under the action of the spring element 580 so that the connection part 510 is placed without contact with the in the side wall of the gap 311 Bring inner clamp 330. This configuration can dampen the force of the contact pins against the conductive element 500 and make the electrical connection of the conductive element 500 to the contact pins much more robust.

Along the mounting direction of the chip 300 to the printer, the inner clamp 330 overlaps with at least a portion of at least one outer clamp. In the present embodiment, the inner clamp 330 is overlapped with at least a portion of the fourth clamp 134, so that the contact area of the second component or the guide element 500 with the inner clamp 330 can be expediently increased to ensure the contact behavior. How out 115 and 116 As can be seen, the inner clamp 330 and the connecting part 510 are each designed as a structure with an inclined surface, so that the contact area of the second component or the guide element 500 with the inner clamp 330 is expediently enlarged to ensure the contact behavior.

How out 117 As can be seen, there is also a pressing part 450 on the ink cartridge. The pressing part 450 is placed in the +X axis of the second component or the guide element 500 and can press on the second component or the guide element 500. When mounting the chip or the color cartridge to the printer, the pressing part 450 will move the second component or the guide member 500 in the -X axis or in a direction of the front surface 310a facing the back surface 310b so that the connecting part 510 can secure the inner clamp 330 the contact behavior is contacted much more positively.

Referring to a thirty-second embodiment

How out 118 As can be seen, the thirty-second embodiment remains different from the thirty-first embodiment in that the second component presses against the first contact pin 915 instead of against the fifth contact pin 915. The second component acts as the guide element 500. The guide element 500 acts as the first terminal and has the functionality of a data terminal. The epitaxial part 530 or the external contact zone 520 serves to send or receive data or signals and also to detect any short circuit between the conductive element 500 and at least one terminal among the second terminal 232, third terminal 233 and fourth terminal 234.

Along the mounting direction of the chip 300 to the printer, the inner clamp 330 overlaps with at least a portion of at least one outer clamp. In the present embodiment, the inner clamp 330 is overlapped with at least one part of the second clamp 132 and the fourth clamp 133, so that the contact area of the second component or the guide element 500 with the inner clamp 330 is expediently enlarged to ensure the contact behavior. The inner clamp 330 and the connecting part 510 are each designed as a structure with an inclined surface, so that the contact area of the second component or the guide element 500 with the inner clamp 330 is expediently enlarged to ensure the contact behavior.

In the present embodiment, the spring element 580 and the conductive element 500 are each placed separately, wherein the spring element 580 as a spring can bring the second component or the conductive element 500 into electrical connection or without electrical connection to the substrate 310. In this way, incorrect mounting of the chip can be avoided and contact robustness can be ensured.

The other arrangements are analogous to those in the thirty-first embodiment.

Alternatively, the guide member 500 may act as the second clamp, the third clamp, or the fourth clamp. The arrangement of the guide member 500 is the same as in the thirty-first or thirty-second embodiment. The conductive element 500, which acts as the second terminal, serves to incorporate the clock signals. The conductive element 500, which acts as the third terminal, serves to include a mains potential that deviates from ground potential (for example 3.6 V or 3.3 V) in order to supply the storage unit with a mains voltage. The guide member 500 acting as the fourth terminal serves to reset the internal data of the wafer.

The preferred exemplary embodiments are described above. It should be noted that the preferred exemplary embodiments do not limit the valid range of the embodiment according to the invention, but only serve to explain the embodiment according to the invention. In this context, all new individual and combination features disclosed in the description and/or drawing are considered essential to the invention. Only the claims are only valid for the scope of protection of the present embodiment.
