Detailed Description

As described in the background art, the image forming apparatus includes an ink cartridge and a printing device, and when the ink cartridge is inserted into the printing device, a chip of the ink cartridge is not grounded or is not grounded stably, which affects the grounding stability and the use safety of the chip; the inventors have found that the cause of this problem is:

In the mounting process of the ink cartridge, the contact pin group of the printing device is exposed in the mounting part thereof, and when the ink cartridge or foreign matter accidentally falls into the mounting part and impacts the ground contact pin, the ground contact pin may be accidentally bent, the contact point is rubbed damaged or the position is not fixed, so that stable contact with the ground sub-terminal of the chip cannot be ensured, and the chip may not be grounded or be grounded unstably. Therefore, in the case where the ink cartridge is excessively high in current, the chip and the printing device may be damaged, and the printing device may not normally recognize the ink cartridge.

In view of the above technical problems, the ink cartridge provided by the embodiments of the present application includes a conductive member and a chip, and a ground terminal of the chip is electrically connected to the conductive member and is electrically connected to a grounding component located in an assembly bin of a printing apparatus through the conductive member. When the ink box is inserted into the printing device, the chip is electrically connected with the grounding component through the grounding terminal and the conducting component, so that the chip is stably grounded.

By the arrangement, the ink box in the embodiment of the application connects the grounding terminal of the chip with the grounding component through the conducting component, so that the situation that the grounding sub-terminal is in unstable contact with the grounding contact pin and the chip cannot be grounded or is in unstable grounding is avoided, the reliability of grounding the chip can be improved, the chip and the printing device are prevented from being damaged due to overlarge current, the use safety of the ink box and the printing device is improved, and the situation that the printing device cannot identify the ink box is reduced.

In order to make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions of the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

As shown in fig. 1 to 3, the ink cartridge 10 according to the embodiment of the present application is used as one of consumable components of a printing apparatus, and the consumable components include, but are not limited to, the ink cartridge 10, for example, the consumable components may also be a cartridge, a ribbon, etc., and the embodiment of the present application is described by taking the ink cartridge as an example.

When the ink cartridge 10 is consumed, the ink cartridge 10 needs to be replaced, and thus the ink cartridge 10 is generally detachably mounted to the printing apparatus. For example, the printing apparatus in the embodiment of the present application may be referred to as a printer having an assembly bay having a mounting portion 90 accommodating an ink cartridge therein and a grounding member for grounding the printer (also referred to as a printing apparatus). The ink cartridge is insertable into the mounting portion and electrically connectable to the mounting portion of the printer to establish communication between the ink cartridge and the printer.

Specifically, the printing apparatus has an assembly bin in which the mounting portion is disposed. The mounting part comprises a containing cavity and a contact pin assembly, wherein the grounding part is positioned at a position outside the position of the contact pin assembly, the containing cavity is used for being inserted by at least one ink box, and at least part of the contact pin assembly is exposed in the containing cavity and is electrically connected with a chip of the ink box. The grounding member is 2 different members from the stylus assembly, in other words, the grounding member is not part of the stylus assembly.

The printing device is provided with an assembly bin, a mounting part and a grounding part, wherein the mounting part and the grounding part are arranged in the assembly bin, the mounting part comprises a containing cavity and a contact pin assembly, the grounding part is positioned at a position outside the position where the contact pin assembly is positioned, the ink box comprises an ink box body, a chip and a conducting component, the chip is arranged on the ink box body, at least one part of the ink box body and the chip can be positioned in the containing cavity, the chip is provided with a communication terminal group and a grounding terminal, and the communication terminal group is electrically connected with the contact pin assembly; the conduction member is disposed within the assembly compartment, and the conduction member is configured to electrically connect the ground terminal and the ground component.

The contact pins in the contact pin assembly can deform, and the grounding part cannot deform; at least one stylus is deformed when the chip is in contact with the stylus; when the conductive member is in contact with the ground member, the ground member is not deformed. Since any two objects are abutted against each other, the contact surface thereof is deformed, and thus the "non-deformable" of the grounding member in this embodiment refers to a small deformation which is not visible to the naked human eye when the grounding member is in contact with the conductive member, as compared with a large deformation of the contact pin.

The ink cartridge 10 includes a cartridge body 50, a chip 20, and a conductive member, wherein the cartridge body 50 is used for containing ink, and the chip 20 is disposed on a surface of the cartridge body 50. The chip 20 is used for storing information such as factory information, ink amount information, ink cartridge type information, ink color and the like of the ink cartridge, and is provided with a plurality of terminals, which can be divided into a communication terminal and a ground terminal according to the purpose of the terminals, that is, a communication terminal group and a ground terminal are provided on the chip, and the communication terminal group includes a plurality of communication terminals.

Further, the communication terminals are configured to contact and electrically connect with respective ones of the contact pins of the contact pin assembly. The grounding terminal is connected with one end of the conducting component, and the other end of the conducting component can be connected with the grounding component, so that a grounding signal of the chip can be transmitted to the grounding component through the conducting component, and the grounding is completed.

When the cartridge 10 is inserted into the receiving cavity, each communication terminal of the chip 20 is in contact with and electrically connected to a corresponding contact pin assembly, so that data transmission, confirmation, data interaction, etc. can be performed between the cartridge 10 and the printer. Meanwhile, the conducting component is electrically connected with the grounding component so as to enable the ink box and the printer to be grounded.

Compared with the scheme that the grounding sub-terminals of the chip 20 are electrically connected with the corresponding grounding contact pins in the contact pin assembly, the ink box in the embodiment of the application connects the grounding terminals of the chip with the grounding component through the conducting component, so that the situation that the grounding terminals are in unstable contact with the grounding contact pins and the chip cannot be grounded or is unstable in grounding can be avoided, the reliability of grounding the chip can be improved, the chip and the printing device are prevented from being damaged due to overlarge current, the use safety of the chip and the printing device is improved, and the situation that the printing device cannot identify the ink box is reduced.

On the basis of the above embodiment, the mounting portion in the embodiment of the present application may be fixed in the assembly bin, or the mounting portion may be movably mounted in the assembly bin, for example, the mounting portion is slidably mounted in the assembly bin. However, the arrangement of the mounting part in the assembly bin is different, so that the arrangement of the ink box and the mounting part is influenced, and the arrangement of the chip on the ink box and the electric connection scheme of the conducting component and the grounding part are also different.

The ink cartridge 10 is mounted in the mounting portion 90 from the opening 95 in the mounting direction P (-Z-axis direction), and the handle 30 is used to fix the ink cartridge 10 to the mounting portion 90, preventing the ink cartridge 10 from being detached from the mounting portion 90.

The ink is stored in the cartridge 50 (also referred to as the cartridge body 50), and reaches the ink supply portion 92 through the ink outlet 41, so that the ink supply portion 92 can supply ink to the print head of the printer, and the ink can be used to perform printing.

As shown in fig. 4, the stylus assembly 91 includes a stylus 91a and a base 910, and the stylus 91a is disposed on the base 910.

In the present embodiment, a three-dimensional rectangular coordinate system, that is, an XYZ axis coordinate system is set, and the three-dimensional rectangular coordinate system of the ink cartridge coincides with the three-dimensional rectangular coordinate system of the mounting portion. When the direction in which the ink cartridge 10 is mounted on the mounting portion is the-Z axis direction, the direction in which the ink cartridge is detached from the mounting portion is the +z axis direction, the opening is located in the +z axis direction, and the bottom wall 90a is located in the-Z axis direction.

The first portion 911a is closer to the mounting location than the second portion 911b, i.e., the first portion 911a may be electrically connected to the chip 20.

The third portion 911c includes a first vertical portion 911k and a second vertical portion 911j perpendicular to the X-axis direction, and a horizontal portion 911h parallel to the X-axis direction, wherein the horizontal portion 911h connects the first vertical portion 911k and the second vertical portion 911j.

As shown in fig. 6 and 7, the chip 20 provided in the present embodiment has a memory 100, a substrate 120, and a plurality of terminals 130 (communication terminal groups). The substrate 120 has a front surface 120a, a rear surface 120b, a left side surface 120c, a right side surface 120d, a top surface 120e (not shown), and a bottom surface 120f.

Wherein the front surface 120a is disposed opposite to the rear surface 120b, and the front surface 120a is located at +x side of the rear surface 120 b; left side 120c is disposed opposite right side 120d, and left side 120c is located on the-Y axis side of right side 120 d; the top surface 120e and the bottom surface 120f are disposed opposite to each other, and the top surface 120e is located on the +z-axis side of the bottom surface 120 f.

Further, the front surface 120a is provided with a plurality of terminals 130, so the front surface 120a is also referred to as a first terminal surface. For example, the front surface 120a is provided with a first terminal 131, a second terminal 132, a third terminal 133, and a fourth terminal 134, and the positions of the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 in the Y axis are different, the positions of the first terminal 131 and the fourth terminal 134 in the Z axis are the same, the positions of the second terminal 132 and the third terminal 133 in the Z axis are the same, but the positions of the first terminal 131 and the third terminal 133 in the Z axis are different.

Further, the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 are each configured as a communication terminal. The first terminal 131 (data terminal) is configured to perform transmission or reception of a data signal; the second terminal 132 (clock terminal) is configured as a clock terminal for receiving a clock signal; the third terminal 133 (power supply terminal) is configured to supply an operating voltage to the memory 100; the fourth terminal 134 (reset terminal) is used to reset the data inside the memory 100.

Each communication terminal has a contact portion C, which is indicated by a circle. The plurality of communication terminals have a plurality of contact portions C, which are first contact portion C1 to fourth contact portion C4, respectively. The contact portion C is the most likely contact area of the contact pin on the terminal 130 when the ink cartridge 10 is mounted to the printer.

The communication terminal group includes a data terminal (first terminal 131), a reset terminal (fourth terminal 134), a power terminal (third terminal 133), and a clock terminal (second terminal 132); the contact portions C1 to C4 of each terminal of the communication terminal group, which are brought into contact with the stylus assembly, are arranged in two rows in the mounting direction P in which the ink cartridge 10 is mounted to the printing apparatus.

In the mounting direction P (i.e., the Z-axis direction in the drawing), the contact portion C1 of the data terminal, the contact portion C4 of the reset terminal are disposed on the upstream side; the contact portion C3 of the power supply terminal and the contact portion C2 of the clock terminal are provided on the downstream side.

In the embodiment of the application, the memory 100 and the communication terminals are respectively disposed on the substrate 120, and the memory 100 needs to be grounded, which can be regarded as a "grounding terminal". The memory 100 needs to be in communication with the printing device for the transmission and interaction of the ground signal so that the ink cartridge is normally installed in the printing device and performs the corresponding task.

The memory 100 is used to store information such as factory information, ink amount information, cartridge type information, ink color, and the like. When the ink cartridge 10 is mounted in the mounting portion of the printer, data transmission, confirmation, data interaction, etc. are performed between the memory 100 and the printer, and both are realized by connection between the communication terminals and the respective contact pins of the printer.

Further, the memory 100 may be disposed on any one or any several of the front surface 120a to the bottom surface 120 f. Preferably, the memory 100 is disposed on the rear surface 120 b. The specific shape structure of the substrate 120 is not limited, and those skilled in the art can set the specific shape structure according to specific design requirements, for example, the chip 20 may be set to a rectangular structure, a corner-cut rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoid structure, or a parallelogram structure.

In addition, the location of the memory 100 on the substrate 120 is not limited, for example, the memory 100 may be disposed on a side of the chip 20 near the rear end of the direction-Z axis, or the memory 100 may be disposed on a side of the chip 20 near the front end of the direction +z axis, or the memory 100 may be disposed in the middle of the chip 20, which is not described herein again.

With continued reference to fig. 6, in this embodiment memory 100 is disposed on rear surface 120b and is disposed adjacent to right side surface 120d and top surface 120 e. The connection member 135 (may also be referred to as a conductive member) is made of a conductive material having a certain hardness, and is connected to the conductive pad 135a (may also be referred to as a ground terminal) by solder, and the conductive pad 135a (may also be referred to as a ground terminal) is connected to the memory 100 through a circuit/conductive wire built in the substrate 120, so that the connection member 135 is connected to the memory 100.

Conductive pad 135a (also referred to as a ground terminal) may be considered as a part of chip 20, and specifically, conductive pad 135a (also referred to as a ground terminal) may be a copper coating (implemented by electroplating) on chip 20, and may electrically connect conductive member 135 and memory 100. The connection 135 (may also be referred to as a conductive member) may be soldered or abutted or otherwise contacted with the conductive tab 135a (may also be referred to as a ground terminal) so long as electrical connection is possible.

A connector 135 (also referred to as a conductive member) is disposed within the assembly compartment, the connector 135 being configured to electrically connect the conductive tab 135a (also referred to as a ground terminal) to a ground component. Further, a ground signal is transmitted between the ink cartridge 10 and the printing apparatus through the ground terminal 135a, the conductive member 135, and the ground means. Optionally, a ground signal is transmitted between the ink cartridge 10 and the printing apparatus through the on-chip memory 100, the conductive member 135, and the ground component. Further, the ground signal is transmitted between the ink cartridge 10 and the printing apparatus through the memory 100, the ground terminal 135a, the conductive member 135, and the ground part on the chip.

Since the connection element 135 (also referred to as a conductive member) is electrically connected to the chip memory 100 and the ground terminal 135a, the connection element 135 (also referred to as a conductive member) can be regarded as the chip 20. That is, the chip 20 includes: memory 100, substrate 120, communication terminal group 130, conductive member 135, and ground terminal 135a.

The contact pins 911-914 in the contact pin assembly 91 are deformable and the ground member is non-deformable; at least one stylus is deformed when the chip 20 is in contact with the styli 911-914; when the conductive member 105 is in contact with the ground part, the ground part is not deformed, and minute deformation invisible to the naked eye is also an undeformable condition. This structure is advantageous in ensuring the stability of the transmission of the electrical signals of the chip 20, in particular the ground signal.

In general, the ground signal is output from the overall CPU of the printing apparatus, and the ground signal is output from the overall CPU to the ground contact pin of the contact pin assembly, the ground member, and the like. When the ink cartridge is mounted on the printing device, the ink cartridge and the printing device are communicated with each other by a grounding signal. In the related art, a grounding signal is transmitted between the ink cartridge and the printing device through the grounding sub-terminal and the grounding contact pin of the chip terminal set in sequence.

However, in the present application, the ground signal is transmitted through the ground terminal, the conductive member, and the ground member. Alternatively, the application transmits the ground signal through a memory on the chip, a conductive member (also referred to as a connector), and a ground component. Optionally, the application transmits the ground signal through the memory on the chip, the ground terminal, the conducting component (also called a connector) and the grounding component, so that the stability of the ground signal transmission can be improved.

The present embodiment describes in detail a layout of a communication terminal group provided on a chip and a ground terminal on a chip substrate.

As shown in fig. 7, the chip 20 in this embodiment includes a substrate 120, where the substrate 120 includes a first surface 120a and a second surface 120b disposed opposite to each other, and the first surface 120a and the second surface 120b are the front surface of the substrate 120, and the second surface 120b is the rear surface of the substrate. The first surface 120a is configured to be the surface of the substrate proximate to the stylus assembly 91 of the printer, the first surface 120a being provided with a set of communication terminals comprising a plurality of communication terminals 131-134.

Further, the chip further includes a ground terminal 135a, the ground terminal 135a is disposed on the first surface 120a or the second surface 120b, and the ground terminal 135a is electrically connected with the conductive member 135 and forms a ground site of the chip.

In one embodiment, the first surface 120a has orthogonal first and second directions, and the first direction is configured as a mounting direction of the ink cartridge 10 to a printing apparatus. Each of the communication terminals has a first projection formed by contacting with the contact pin and having a first projection corresponding to the first surface 120a, the first projections of the plurality of first contact portions on the first surface 120a enclose a first area, and the grounding point formed by the conductive member and the grounding terminal has a second projection on the first surface 120 a.

In the second direction, at least part of the second projection is located outside the first region, in other words, in the second direction, part of the second projection is located inside the first region, and at least part of the second projection is located outside the first region. For example, part of the second projection is located outside the first region, in which case in the second direction the second projection is located closer to one side of the first region and the distance from the first region is smaller than the length of the first region. Optionally, in the second direction, the second projection coincides with the first region.

The chip 20 may have the following modifications, and various modifications may be mounted on the ink cartridge 10.

Modification of the chip:

As shown in fig. 8 to 10, the present modification differs from the chip of the first embodiment in that: the chip 20 according to the present modification example includes the memory 100, the substrate 120, and the terminal group (corresponding to the communication terminal group of the first embodiment).

The memory 100 and the terminal group (corresponding to the communication terminal group of the first embodiment) are provided on the chip substrate 120, and the memory 100 is used for storing information such as factory information, ink amount information, consumable cartridge type information, ink color, and the like. When the consumable cartridge 10 is mounted in the mounting portion 90 of the printer, data transmission, confirmation, data interaction, etc. are performed between the memory 100 and the printer, and both are achieved through connection between the terminal set and the printer contact pins. Further, the shape of each terminal in the terminal group may be other shapes, such as: rectangular, square, circular, trapezoidal, or other irregular shape.

The present modification provides a terminal group including a plurality of terminals (131-139) on the front surface 120 a. Of course, the memory 100 may be disposed on any one or any of the front surface 120a, the bottom surface 120f, and the top surface 120e and the bottom surface 120f may be disposed opposite to each other in the Z-axis direction. The specific shape structure of the chip 20 is not limited, and a person skilled in the art may set the chip 20 according to specific design requirements, for example, a rectangular structure, a corner-cut rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoid structure, and a parallelogram structure may be provided.

In addition, the location where the memory 100 is disposed is not limited, for example, the memory 100 may be disposed on a side of the chip 20 near the rear end in the mounting direction, or the memory 100 may be disposed on a side of the chip 20 near the front end in the mounting direction, or the memory 100 may be disposed in the middle of the chip 20, which may be set by a person skilled in the art according to specific design requirements and will not be described herein.

The terminal group in this embodiment includes 9 terminals, and functions and roles of each terminal are as follows: a first terminal 131; second terminal 132 (reset terminal): the method is used for resetting the internal data of the wafer; third terminal 133 (clock terminal): for receiving a clock signal; a fourth terminal 134; a fifth terminal 135; sixth terminal 136 (power supply terminal): for receiving a power supply potential (e.g., 3.6V) other than the ground potential, through which power is supplied to the operation of the memory 100; seventh terminals 137a, 137b, 137c, 137d (ground terminals): for indirectly receiving a ground potential; eighth terminal 138 (data terminal): a ninth terminal 139 for transmitting or receiving a data signal.

In this embodiment, the third terminal group includes a first terminal 131 and a fourth terminal 134, the second terminal group includes a fifth terminal 135 and a ninth terminal 139, and the third terminal group and the second terminal group are both installation detection terminals, where the first terminal 131 and the fourth terminal 134 may also be short circuit detection terminals, and the other terminals are the first terminal group. When the consumable cartridge 10 is mounted to the printer, electric signal transmission occurs between the mounting detection terminal and the printer, and detection is made as to whether the consumable cartridge 10 is mounted. In addition, the fifth terminal 135 and the ninth terminal 139 are also referred to as high-voltage terminals for receiving a mounting detection voltage (for example, 42V) to perform a mounting detection function of the consumable cartridge to the mounting portion.

For example, a high resistance (e.g., 62kΩ) is connected between the fifth terminal 135 and the ninth terminal 139, and it is determined whether the consumable cartridge 10 has been mounted in the mounting portion by detecting a change in current or voltage. First terminal 131, fourth terminal 134: also called a short-circuit detection terminal, detects whether there is a short circuit on the chip 20 by detecting a voltage change on the terminal; and whether the consumable cartridge 10 is mounted to the printer can be determined by whether the two are connected.

The first terminal 131 and the fourth terminal 134 are also used for detecting whether a short circuit occurs between the terminals, specifically, for detecting whether a short circuit occurs between the fifth terminal 135/the ninth terminal 139 and the first terminal 131/the fourth terminal 134. When the fifth terminal 135/ninth terminal 139 and the first terminal 131/fourth terminal 134 are shorted, the printer can detect that the voltage at the first terminal 131/fourth terminal 134 is raised, and then the printer prompts the short-circuit information, so that the risk of damaging the chip or the printer due to short-circuit is avoided.

Each terminal in the terminal set has a respective contact portion, represented by dots in fig. 8. The contact is the most likely contact area of the contact pin on the terminal when the consumable cartridge 10 is mounted to the printer. The ground terminals (seventh terminals 137a, 137b, 137c, 137 d) are arranged in the order of one second contact portion, one third contact portion, the first contact portion, the other third contact portion, or the other second contact portion, or the ground terminal is aligned with the fifth terminal 135 in the Z direction (as shown in fig. 8), as viewed in the direction perpendicular to the mounting direction P, but of course, the ground terminals may be provided on the chip front surface 120a or the rear surface 120b, for example, the ground terminals may be arranged in four positions of 137a, 137b, 137c, 137d shown in fig. 8, 9, and in this embodiment, the ground terminals 137a, 137b, 137c, 137d are preferably provided on the front surface 120a or the rear surface 120b in such a manner that the ground terminals are located in the +z direction of the fifth terminal 135 or are biased to the-Y direction side in the +z direction.

Alternatively, the ground terminal (seventh terminal) is in line with the first terminal 131 along the Z direction. Alternatively, the ground terminal (seventh terminal) overlaps at least a part of the first and fifth terminals 131, 135 along the Z direction. Alternatively, the ground terminal (seventh terminal) overlaps at least a portion of the first terminal 131 along the Z direction. Alternatively, in the Z direction, the ground terminal (seventh terminal) overlaps at least a portion of the fifth terminal 135. Optionally, in the Z direction, the ground terminal (seventh terminal) overlaps at least a portion of the fourth terminal 134, the ninth terminal 139. Alternatively, the ground terminal (seventh terminal) overlaps at least a portion of the fourth terminal 134 along the Z direction. Alternatively, in the Z direction, the ground terminal (seventh terminal) overlaps at least a portion of the ninth terminal 139. The ground terminal (seventh terminal) is electrically connected to the memory 100 and the conductive member 140.

As shown in fig. 11, in the present embodiment, the memory 100 is disposed on the rear surface 120b, where the rear surface 120b of the substrate 120 is close to the right side surface 120d and the top surface 120e, the connection member 140 (corresponding to the conductive member of the first embodiment, made of a conductive material having a certain hardness) is connected to the conductive sheet 140a (corresponding to the ground terminal of the first embodiment) by soldering/abutting, and the conductive sheet 140a is a contact prepared on the rear surface 120b of the substrate, and this contact is connected to the memory 100 by a conductive wire disposed inside the substrate 120, so as to electrically connect the connection member 140 and the memory 100.

Chip modification II:

The present modification differs from the chip of the first embodiment in that: as shown in fig. 12 and 13, the terminal group 130 on the substrate includes four communication terminals defined as a first terminal 131, a second terminal 132, a third terminal 133, and a fourth terminal 134, respectively, wherein the first terminal 131 (data terminal) is used for transmission or reception of a data signal; a second terminal 132 (clock terminal) for receiving a clock signal; a third terminal 133 (power supply terminal) for receiving a power supply potential (e.g., 3.6V/3.3V) different from the ground potential, through which power is supplied for the operation of the memory; the fourth terminal 134 (reset terminal) is used to reset the data inside the die or to bring the processing device to a responsive state.

Each contact C1-C4 has a first projection on a first surface, wherein the first surface comprises orthogonal first and second directions; wherein the first direction is configured as a mounting direction P in which the ink cartridge is mounted to the printing apparatus, in which case the first surface is parallel to the first direction (i.e., the mounting direction P); or the first direction is configured as an extending direction of projection lines of the mounting direction P of the ink cartridge to the printing apparatus on the first surface, and the first surface may be inclined with respect to the first direction, that is, the substrate is disposed obliquely on the cartridge body.

For example, the first direction in the drawing is a Z-axis direction, the X-axis direction is a second direction, and the second direction is perpendicular to the first direction, where the first surface may be the front surface 120a or the rear surface 120b of the substrate. The first projection of each contact portion on the first surface encloses a first area M. For example, the substrate includes a region Q1 and a region Q2 arranged along the substrate center line, and the first region M is located in the region Q1, the first terminal to the fourth terminal are all located in the region Q1, and each formed contact is located in the first region M, which is naturally located in the region Q1.

Further, the rear surface of the substrate is further provided with a ground terminal, which may be referred to as a fifth terminal/additional terminal, wherein the ground terminals 135a, 135b, 135c, 135d (corresponding to the ground terminals of the first embodiment) connect the conductive member and the memory, and the ground terminal is connected to the conductive member and forms a ground point. The ground terminals may be arranged at four locations 135a, 135b, 135c, 135 d.

For example, the first to fourth terminals are all located in the region Q1. Further, the area Q2 may be eliminated or minimized, thereby reducing the chip size and achieving miniaturization of the chip, ink cartridge, and printer. When the area Q2 is eliminated or as small as possible, the area Q1 refers to a chip area where the first terminal 131 to the fourth terminal 134 are located, and the contact portions of the first terminal 131 to the fourth terminal are located in the first area M.

The location of the ground terminals 135a, 135b, 135c, 135d may be on the area Q1 on the rear surface 120 b. For example, as shown in fig. 13, the second projection of the ground point formed in this case on the first surface is located in the region Q1 at the position shown by the first additional terminal 135a or the second additional terminal 135b, and the second projection partially coincides with the first region M. Or the position of the fifth terminal 135 may be on the area Q1 on the front surface 120a, for example, the position shown by the fourth additional terminal 135d, where the second projection of the ground point formed on the first surface is located in the area Q1, i.e. the second projection is located outside the first area M.

In other embodiments, the location of the fifth terminal 135 may be on the second region Q2 on the rear surface 120 b. For example, in the position shown by the third additional terminal 135c in fig. 13, the second projection of the ground point formed on the first surface is located outside the first area Q1, that is, the second projection is located outside the first area M. Further, in some embodiments, the width of the region Q2 in the X-axis direction may be smaller than the width of the region Q1 direction, and the distance between the side of the second projection close to the first region M and the first region may be smaller than the length of the first region.

The difference between the embodiment of the present application and the foregoing embodiment is that:

As shown in fig. 17 to 20, the grounding member provided by the embodiment of the present application includes a grounding rail 80, and the grounding rail 80 is grounded. The ground rail 80 is disposed within the assembly compartment, and the mounting portion 90 is slidably disposed on the ground rail 80, i.e., the ground rail 80 not only acts as a load bearing member for the mounting portion 90, but also as a ground member for transmitting ground signals.

In one embodiment, the side of the grounding rail 80 facing the mounting portion is provided with a conductive wall plate 81, and the conductive wall plate 81 is connected to the grounding member, which may be a unitary structure, which is not limited in this embodiment of the present application. The length extension direction of the conductive wall plate 81 coincides with the extension direction of the ground rail 80, and the conductive wall plate 81 intersects with a horizontal plane, for example, the conductive wall plate 81 is perpendicular to the horizontal plane, or the conductive wall plate 81 is disposed obliquely with respect to the horizontal plane.

Specifically, the ink cartridge 10 of the present embodiment further has a connector 135 (corresponding to a conductive member), where the connector 135 is used to connect the chip 20 and other metal parts (corresponding to a grounding part) of the printing device, so as to implement the grounding function of the chip 20, i.e., the connector 135 is configured as a conductive member. For example, connector 135 includes a connector body 135bb and a conductor 135cc, wherein connector body 135bb and conductor 135cc may be integrally or separately provided, as embodiments of the application are not limited in this respect. The connecting member 135 may be a metal member such as copper, aluminum, steel, or a member made of conductive silica gel, conductive plastic, or the like.

One end of the connecting member 135 near the chip is electrically connected to a conductive sheet 135a (corresponding to a ground terminal), wherein the conductive sheet 135a is disposed on the substrate 120 and electrically connected to the memory of the chip 20, and the memory needs to be grounded, and the connection manner between the conductive sheet 135a and the memory is not limited. For example, conductive tab 135a may be connected to the memory via a conductive wire, thereby connecting connector 135 to the memory. The position of the conductive sheet 135a on the substrate 120 is not limited, in this embodiment, the conductive sheet 135a is disposed on the rear surface 120b of the chip, and is located on a different surface of the substrate from other terminals on the chip 20, so that the conductive sheet 135a is ensured not to be shorted to other terminals, the stability of the grounding of the chip is ensured to be good, and the use safety of the chip is improved. The conductive pad 135a (corresponding to a ground terminal) is copper-clad on the chip 20 by a process such as electroplating.

The conductor 135cc is provided on the cartridge body 50 to be in contact with other metal parts (equivalent to a grounding member) on the printer. Preferably, the conductor 135cc is disposed inside the cartridge body 50, avoiding contact with external objects, damaging the conductor 135cc, ensuring a stable implementation of the grounding function of the connection member 135. In this embodiment, conductor 135cc is disposed within handle 30. Connection body 135bb is used to connect conductive sheet 135a and conductor 135cc.

Specifically, the connection body 135bb has a first portion 135b1, a second portion 135b2, and a connection portion 135b3. The first portion 135b1 is for connection with the conductive sheet 135 a. The material of the first portion 135b1 and the connection manner with the conductive sheet 135a are not limited, for example, the first portion 135b1 may be made of a conductive material having a certain hardness and may be connected to the conductive sheet 135a by soldering.

In some other embodiments, the connection member 135 (corresponding to the conductive member) may not be provided with the conductive sheet 135a, that is, the first portion 135b1 is directly connected to the memory (not shown in the drawing) of the chip 20. The connection manner of the first portion 135b1 to the memory is not limited, and for example, the first portion 135b1 may be directly connected to a conductive line connected to the memory by solder. Second portion 135b2 is for connection with conductor 135 cc. The connection portion 135b3 is for connecting the first portion 135b1 and the second portion 135b2. Preferably, the connecting portion 135b3 is disposed in a corresponding groove on the ink cartridge body 50, so as to prevent the connecting portion 135b3 from being damaged by external objects and to influence the conductive function of the connecting member 135, and also to perform a fixing function.

As shown in fig. 21 and 22, in the present embodiment, a conductor 135cc is provided in the handle 30. The handle 30 includes a main body 301, an extension 302, a restricting portion 303, an engaging portion 304, and a connecting portion 305. The extension portion 302, the restricting portion 303, the engaging portion 304, and the connecting portion 305 are respectively disposed on the main body portion 301, and a manner of disposing the extension portion, the restricting portion, the engaging portion, and the connecting portion on the main body portion 301 is not limited, and may be, for example, a detachable connection, a fixed connection, or the like.

One end of the extension portion 302 in the X-axis direction is connected to the main body portion 301, and the other end is in contact with other metal portions (equivalent to a grounding member) on the printer. In this embodiment, the other end of extension 302 is in contact with conductive wall 81 of the printer so that conductor 135cc is in contact with conductive wall 81 to form an electrical connection. Extension 302 serves to protect conductor 135cc from bruising, breaking, positional displacement, etc.

Compared with the contact area of the chip grounding terminal on the contact pin in the existing ink box mounting part, the contact area of the conductive wall plate 81 and the connecting piece 135 is larger, so that the connecting piece 135 and the grounding guide rail 80 can be ensured to be electrically connected stably and accurately to be contacted, the grounding function of the chip 20 is ensured to be stably realized, excessive current is prevented, and the probability of electric shock danger caused by unstable grounding is reduced.

On the basis of the above embodiment, the extension portion 302 in the embodiment of the present application is further provided with a color recognition portion 302a for indicating the color of ink stored in the ink cartridge. The ink color indication method of the color identification unit 302a is not limited, and for example, the color of the ink stored in the ink cartridge may be indicated by a color, a pattern, a character, a combination thereof, or the like.

The restricting portion 303 cooperates with a restricting projection 502 provided on the ink cartridge to restrict the movable range of the handle 30 in the X-axis direction. The position and shape of the restricting projection 502 on the ink cartridge body 50 are not limited, and for example, the restricting projection 502 may be a cylinder, may be a cone, may be an irregularly shaped projection, or the like. The restricting projection 502 is a cylinder in this embodiment.

The engagement portion 304 cooperates with a fixing portion 90d provided on the mounting portion 90 for fixing the ink cartridge 10 to the mounting portion 90, preventing the ink cartridge 10 from being detached from the mounting portion 90. The connection portion 305 is used to connect the handle 30 to the ink cartridge body 50, and the connection manner of the connection portion 305 and the ink cartridge body 50 is not limited, and may be, for example, a detachable connection, a fixed connection, or the like. In some other embodiments, the handle 30 may not be provided with the connection portion 305, and the main body portion 301 is directly connected to the ink cartridge body 50.

When the cartridge 10 is mounted to the mounting portion, one end of the connecting member 135 is a conductive sheet 135a, which is connected to the memory on the cartridge chip 20, and receives the current output from the chip 20. Conductive tab 135a passes the received current to conductor 135cc through connecting body 135 bb. The other end of the connector 135 is a conductor 135cc, which is connected to other metal parts on the printer, and transfers the current received from the connection body 135bb to the other metal parts on the printer, thereby realizing the chip grounding function.

Specifically, conductor 135cc is penetratingly disposed within handle 30, and conductor 135cc is penetratingly disposed within body portion 301, extension portion 302 and connection portion 305 of handle 30. Because the engaging portion 304 provided on the handle body portion 301 cooperates with the fixing portion 90d provided on the mounting portion 90, for fixing the ink cartridge 10 to the mounting portion 90, the conductor 135cc is disposed in the handle 30 in a penetrating manner, and is closer to the engaging portion 304 on the handle 30, so that stable and accurate contact between the connector 135 and other metal portions on the printer can be ensured, stable grounding of the chip 20 can be ensured, excessive current is prevented, and the probability of electric shock hazard due to unstable grounding is reduced. The chip grounding stability is guaranteed to be good, the use safety of the chip is improved, and the situation that the printing device cannot identify the ink box is reduced.

Third embodiment of example one:

Fig. 23 to 26 are related schematic views of a third embodiment of the first embodiment of the present application. The present embodiment differs from the second embodiment in that: as shown in fig. 23 to 26, fig. 23 is a schematic view of the ink cartridge 10 mounted to the mounting portion 90, the ground part having a ground rail having a conductive wall plate 81, and the conductive member 105 thereof being in contact with the conductive wall plate 81 and transmitting a ground signal. A baffle 84 is provided in the +z axis direction of the conductive wall plate 81.

Typically, the baffle 84 is made of a plastic and non-conductive material. In the X-axis direction, the end of the shutter 84 is closer to the mounting portion 90 than the end of the conductive wall plate 81 (i.e., the end of the shutter 841 is located on the +z-axis, -X-axis side than the conductive wall plate 81), so that the conductive member 105 needs to pass over the shutter 841 before coming into contact with the conductive wall plate 81 when the ink cartridge 10 is mounted to the printing apparatus.

One end of the conductive member 105 in this embodiment is in contact with the ground terminal 135a on the chip 20, and the other end is in contact with the conductive wall plate 81 of the ground component. The transmission path of the ground signal is in turn: the memory of the chip 20, the ground terminal 135a, the conductive member 105, the conductive wall 81 of the ground component.

The handle 30 has: the main body 301, the extension 302, the engagement 304, the first gap 308, and the second gap 309. The cartridge is also provided with a fixing portion 307 for fixing the conductive member 105. The extension 302 includes a flat portion 3025, a first bent portion 3021, a second bent portion 3022, an abutment receiving cavity 3023, and a fixing aperture 3024. The purpose of the extension 302 is to: the fixed conduction member 105 and the conduction member 105 are abutted against the conductive wall plate 81 across the baffle 84 and the conduction member 105. The extension 3025 extends in the +x direction for better contact between the conductive member 105 and the conductive wall 81.

The first bending portion 3021 extends from the extension portion 3025, and the first bending portion 3021 extends in the +x axis direction (the direction in which the conductive wall plate 81 is located) and the +z axis direction (the upper direction); the second bending portion 3022 extends from the first bending portion 3021, and the second bending portion 3022 extends in the-X axis direction (the direction away from the conductive wall plate 81/the direction toward the case body) and the +z axis direction (the upper direction), and this structure is designed to allow the extending portion 302 and the conductive member 105 to pass over the baffle 84 during the process of mounting the ink cartridge 10 to the printing apparatus, and the second bending portion 3022 can guide the deformation/compression of the handle 30 when the ink cartridge 10 is taken out from the printing apparatus, thereby facilitating the taking out of the ink cartridge 10.

The abutment accommodating chamber 3023 accommodates an abutment portion 1057 of the conductive member 105, and the abutment portion 1057 is configured to abut the conductive member 105 against the conductive wall plate 81. The abutment receiving chamber 3023 is a relatively concave portion, and protects the abutment portion 1057 to some extent, thereby reducing damage. The abutment accommodating chamber 3023 is provided at a position where the first bent portion 3021 and the second bent portion 3022 intersect, such that the abutment portion 1057 is located at a position closest to the +x axis of the ink cartridge 10, so that the conductive member 105 abuts against the conductive wall plate 81.

Further, the fixing hole 3024 cooperates with the elastic portion 1056 to firmly fix the conducting member 105 to the ink cartridge 10, so as to prevent the conducting member 105 from being separated from the ink cartridge 10. The handle 30 is extended from the cartridge body 50, has a certain elasticity, is contractible toward the-X axis direction, and is restored to its original position. The extension portion 302 is located on the handle 30, so that the extension portion 302 also has a certain elasticity, and can move towards the-X axis direction, so that the conducting member 105 can pass over the baffle 84, and can move towards the +x axis when the handle 30 is compressed, so that the abutting portion 1057 can have a pressing force, and the abutting portion 1057 can better abut against the conductive wall plate 81. The abutment portion 1057 is located at a position where the first bent portion 3021 and the second bent portion 3022 intersect.

The conductive member 105 includes a first portion 1051a, a second portion 1051b, and a third portion 1051c. The first portion 1051a is fixed to the ink cartridge body 50, and specifically, the conductive member 105 is prevented from being separated from the ink cartridge body 50 by the engagement of the through hole 1053 with the fixing portion 307. The through hole 1053 may be tightly fitted with the fixing portion 307.

Alternatively, after the through hole 1053 is matched with the fixing portion 307, a portion of the through hole 1053 protruding from the fixing portion 307 may be laid on the first portion 1051a by welding and hot melting, so as to prevent the conductive member 105 from being separated from the ink cartridge body 50. The second portion 1051b is fitted to the main body 301 of the handle 30, and a first gap 308 is provided on the-X axis direction side of the engagement portion 304 and the +x axis direction side of the main body 301, and the first gap 308 accommodates a part of the second portion 1051 b. The third portion 1051c is fitted to the extension 302, so that the conductive member 105 can better abut against the conductive wall plate 81.

The third section 1051c has thereon: an abutting portion 1057, and an elastic portion 1056. The abutment 1057 is provided in the abutment accommodation chamber 3023. The resilient portion 1056 is a flexible sheet member extending from the conductive member 105 and is engageable with the securing aperture 3024 to secure the conductive member 105 to the handle 30. The conductive member 105 has a first bending region AA extending in the direction of the conductive wall plate 41 and a second bending region BB connected to the first bending region AA and extending in the upward direction (+z-axis direction), and a position where the conductive member 105 contacts the conductive wall plate 81 is located on the second bending region BB, that is, the abutting portion 1057 is located on the second bending region BB.

The first bending region AA is aligned with the first bending portion 3021 of the extension 302, and extends in the +x axis direction (the direction in which the conductive wall plate 81 is located) and the +z axis direction (the upper direction), and the second bending region BB is a portion accommodated in the abutment accommodating chamber 3023, which is connected to the first bending region AA and extends in the upper direction (+z axis direction), and this structure facilitates the abutment of the conductive member 105 with the conductive wall plate 81. The abutment portion 1057 is a protrusion on the second bending region BB, and the abutment portion 1057 may be an arc-shaped, spherical, linear, or dot-shaped protrusion, preferably, the abutment portion 1057 is a spherical protrusion (as shown in fig. 26), which facilitates the abutment with the conductive wall plate 81 and can reduce the friction between the abutment portion 1057 and the conductive wall plate 81 as the ink cartridge 10 slides along with the mounting portion 90, so as to ensure smoothness of the ink cartridge 10 during the sliding process.

Since the handle 30 is elastic, it is retractable and returns to its original state. The handle 30 is different in a natural state and a state of being attached to the printing apparatus. The conducting member 105 also has 2 states: an initial state and an abutting state. The conductive member 105 may be switched between an initial state and an abutment state. The conductive member 105 is farther from the ink cartridge body 50 in the initial state than in the abutting state. The abutting portion 1057 is further away from the ink cartridge body 50 in the initial state than in the abutting state, and after the ink cartridge 10 is mounted to the printing apparatus, the abutting portion 1057 of the conductive member 105 has a pressing force against the conductive wall plate 81, so that the abutting portion 1057 can be better abutted against the conductive wall plate 81.

Note that, the conductive member 105 is made of a conductive material, such as: metal, conductive silicone, conductive plastic, and the like. Alternatively, the conductive member 105 is made of metal and is bent into the structure shown in fig. 23 to 25. The abutting portion 1057 may be manufactured by hot pressing, and the originally planar metal plate surface is hot pressed to form a spherical protrusion; the elastic portion 1056 may be made by punching, and one end of the elastic portion 1056 is punched to form a suspended elastic portion 1056; the through hole 1053 may be formed by punching.

Similar to the first embodiment, the terminals 131 to 134 disposed on the front surface in this embodiment are all communication terminals, and the application and layout of each communication terminal on the front surface are the same as those of the first embodiment, and are not described here again.

The connection 60 (corresponding to the conductive member of the first embodiment) and the memory 100 may also be connected to each other by a fifth terminal/additional terminal 135a (corresponding to the ground terminal of the first embodiment) and a wire thereof. It is understood that the fifth terminal 135a may not be provided in the present embodiment, and the connector 60 may be directly connected to the memory 100. Preferably, the use of the fifth terminal 135a makes the connection of the connector 60 with the memory 100 more efficient and more stable.

Further, the conductive member and the fifth terminal/additional terminal 135a may be connected by soldering, fixing. Each terminal 130 has one contact portion, which is a first contact portion-a fourth contact portion, respectively. The contact is the most likely contact area of the contact pin on the terminal 130 when the cartridge is mounted to the printer.

In the embodiment of the application, the connecting piece 60 is used as a conducting component, the connecting piece 60 is made of conductive materials, and a grounding signal of the printer is communicated with the memory through the conducting component and the fifth terminal/additional terminal (equivalent to a grounding terminal), so that the chip of the ink box and the grounding component are commonly grounded.

As shown in fig. 37 to 42, the connection member 60 includes a first portion 60a and a second portion 60b. Wherein the first portion 60a is used to connect the second portion 60b with the fifth/additional terminal 135a of the chip 20; the second portion 60b is used to connect the metal piece 96, the first portion 60a.

The shape of the first and second portions 60a, 60b is not limited and may be provided in a regular shape, such as rectangular, or in a meandering or other irregular shape. In addition, the first portion 60a may be integrally formed, or may be formed by splicing a plurality of metal sheets.

Further, the connector 60 may also be a unitary structure without the first and second portions 60a, 60b. When the conductive member includes the first portion 60a and the second portion 60b, the structure of the first portion 60a is simplified, and the second portion 60b can be manufactured in a more complex structure.

For example, the second portion 60b may also be used as a handle 30 for the ink cartridge, which may function as a handle during loading and unloading of the ink cartridge during its mounting to the tray 97, for easy handling by a user. By the arrangement, the transmission of the grounding signal can be completed, and the effect of simplifying the structure of the ink box (reducing the production, manufacturing and assembly of parts of the handle) can be achieved. Therefore, the structure can reduce the number of parts, simplify the partial structure of the ink box and reduce the cost.

Further, the first portion 60a of the connector 60 has: a first connection portion 60aa, a second connection portion 60ab. The first connection portion 60aa is for connection with a fifth terminal or additional terminal 135 of the chip 20; the second connection portion 60ab is for connection with the second portion 60 b.

The second portion 60b has: a first connection portion 60ba, a second connection portion 60bb. Wherein the second connection portion 60bb is for connection with the second connection portion 60 ab; the first connection portion 60ba is for abutting against the metal piece 96.

Specifically, the first connection portion 60ba abuts against the +z-axis surface of the metal member 96, and the transmission of the ground signal is completed. The first connection 60ba is not necessarily at the end of the second portion 60 b; as shown in fig. 41 to 42, the first connecting portion 60ba is provided at a middle position of the second portion 60 b. The first connection portion 60ba may be combined in one or more positions.

As shown in fig. 41, the first connection portion 60ba may be 3 different positions. Since the second portion 60b needs to function as a handle in addition to the abutment metal piece 96, the first connecting portion 60ba is on the-Z axis direction side of the second portion 60b in the Z axis direction. In the Z-axis direction, the first connection portion 60ba is located on the-Z-axis direction side of the second connection portion 60 bb; the second portion 60b is located on the-Z axis direction side of the first portion 60 a; the first portion 60a is located on the-Z-axis direction side of the chip 20.

That is, the first connection portion 60ba is located on the-Z axis, -Y axis direction side of the second connection portion 60 bb; the second portion 60b is located on the-Z-axis, -Y-axis direction side of the first portion 60 a; the first portion 60a is located on the-Z-axis, -Y-axis direction side of the chip 20.

It should be noted that the metal piece 96 contacted by the second portion 60b may be any metal piece that can be electrically conductive at any place of the printer. Preferably, the position of the metal piece 96 contacted by the second portion 60b is located at the uppermost portion of the ink cartridge 10 in the Z-axis direction.

Further, with continued reference to fig. 34 and 37, when the ink cartridge is mounted on the mounting portion 90, the columnar positioning portions 53f and 53s cooperate with the positioning holes 97a and 97b of the tray 97 and the hole portions 42a and 42b of the ink cartridge to restrict the position of the assembly at the mounting portion; the ink supply tube 92 (corresponding to the ink supply portion 92 of the first embodiment) is matched with the ink outlet 41, and can supply ink for printing by the printer; the stylus assembly 91 is in contact with the chip 20, providing for the transmission of chip signals.

The protrusions on the locking portion 94 are used to cooperate with the grooves on the bottom of the tray 97 to fix the combination of the ink cartridge and the tray 97. The connector 60 is in contact with the metal piece 96 to transmit a ground signal. The connecting member 60 serves as a handle in the loading and unloading process of the ink cartridge during the process of mounting the ink cartridge on the tray 97, and facilitates the operation of loading and unloading the ink cartridge by a user.

The number and shape of the positioning holes 97a/97b in the tray 97 and the hole portions 42a/42b in the ink cartridge are not limited. For example, one or more than one positioning holes can be formed, and the shape can be round, square or other irregular shapes, so that the ink cartridge can be stably matched with the printer and stably installed.

Further, with continued reference to fig. 37 to 40, the ink cartridge in the present embodiment has an ink supply head 40 and an ink bag 10a in which ink is stored. Wherein, the chip 20 and the connecting member 60 are disposed on the ink supplying head 40. The ink supply head 40 is provided with an ink outlet 41 on the +x side, and the ink outlet 41 communicates with the ink bag 10a through a lead-out flow path inside the ink outlet 41, so that ink stored inside the ink bag 10a is supplied to the printer through the ink outlet 41.

Referring to fig. 40, the +z axis side of the ink supply head 40 is provided with a shaft hole with which the shaft of the second portion 60b is fitted. The +Z-axis side of the ink-supply head 40 is further provided with a supporting member 102, which is located on the +Z-axis side of the second portion 60b, and on the-Y-axis side of the shaft hole, and which supports at least a part of the second portion 60 b.

Specifically, in this embodiment, the supporting member 102 is a protrusion extending from the upper surface of the ink head 40 toward the +z axis direction, and along the +z axis direction, the supporting member 102 is higher than the above axis, and in the ink cartridge mounted state, at least part of the second portion 60b is in contact with the supporting member 102 and is located on the +z axis side of the supporting member 102.

Therefore, in the mounted state, the second portion 60b is inclined to the-Y axis side, -Z axis side by the support 102, and the-Z axis end of the second portion 60b is in contact with and electrically connected to the metal piece 96 above the ink cartridge, so that it is possible to realize: the first connection portion 60ba is located on the-Z axis, -Y axis direction side of the second connection portion 60 bb; the second portion 60b is located on the-Z-axis, -Y-axis direction side of the first portion 60 a.

The arrangement reduces the risk of electric shock hazard caused by unstable grounding, ensures that the chip is grounded with good stability, and improves the use safety of the chip. Meanwhile, the ink box is convenient for a user to operate and load and take the ink box.

The number and shape of the supporting members 102 are not limited, and specifically, the supporting members 102 may be provided in one, two or more, and may be provided in a rectangular parallelepiped, a cylinder or a triangular prism or other regular or irregular shape, so long as the second portion 60b can be supported and can be brought into stable contact with the metal member 96.

Preferably, the contact area of the second portion 60b with the metal member 96 is closer to the left side 120c of the chip substrate 120 than the right side 120d of the chip substrate 120 is to the X-axis direction. Preferably, the abutting region of the second portion 60b and the metal piece 96 may not be provided on the first connecting portion 60ba as shown in fig. 41, but may be provided within the region of the first region R1.

As shown in fig. 41, the portion of the second portion 60b connected to the metal piece 96 is: the third connection portion 60bc. The third connection portion 60bc is located at the first region R1, and the second portion 60b is disposed obliquely (this oblique manner may be achieved by the difference in height of the plurality of supports 102) in the X-axis direction, and the third connection portion 60bc is located at the +z-axis end of the second portion.

It should be noted that, during the process of mounting the ink cartridge 10 to the printing apparatus, the connection member 60 (conductive member) contacts the ground part first, and the chip 20 contacts the contact pin assembly 91 later.

Third embodiment of example three:

In a third embodiment, the present embodiment further provides a new conducting member based on the second embodiment, wherein one end of the conducting member is electrically connected to the ground terminal of the chip, and the other end of the conducting member is electrically connected to at least part of the cavity wall of the mounting cavity, and the electrically connected position of the conducting member and the ground terminal is located above the chip.

As shown in fig. 43 and 44, the chip provided in this embodiment is different from the third embodiment in that: the chip 20 is provided with a recess 21. The function of the recess 21 is: avoiding the fifth contact pin 915, preventing the fifth contact pin 915 from abutting or contacting the chip 20; that is, when the ink cartridge 10 is mounted to the mounting portion of the printer, a part of the fifth contact pin 915 is located in the recess 21, and the fifth contact pin 915 does not abut or contact the chip 20.

The chip 20 may not have the recess 21, and if there is no terminal/contact portion in the X-axis direction of the chip that can be connected to the fifth contact pin 915, even if the chip 20 is in contact with the fifth contact pin 915, there is no electrical connection between the two, and no transmission of a ground signal occurs.

As shown in fig. 45 to 51, the ink cartridge 10 includes: chip 20, connector 70 (corresponding to the conductive member of the first embodiment), ink supply head (may also be referred to as a base) 40 and ink bag 10a; the chip 20 is provided on the front end side of the mounting direction D2 of the ink cartridge 10; the connection member 70 is configured as a conductive member, and the conductive member is a conductive material, wherein a portion of the connection member 70 is connected to the chip 20, and another portion is connected to the metal member 96 (corresponding to the grounding member of the first embodiment) of the mounting portion 90. For example, the connector 70 is connected to the +z-axis lower surface 96a of the metal piece 96, that is, the connector 70 is connected to the lower surface 96a of the metal piece 96 (corresponding to the grounding member of the first embodiment) facing the mounting portion 90.

The ground signal between the chip 20 and the printer is transmitted through the connector 70, the metal piece 96. After the technical scheme is adopted, the grounding signal is transmitted to the chip 20 through the metal piece 96 and the connecting piece 70, so that the stability is improved, and the situation that the grounding cannot be carried out or the grounding is unstable is reduced.

Further, in the present embodiment, the first terminal 131 to the fourth terminal 134 are provided on the front surface 120a of the chip 20, and the fifth terminal 135 is provided on the rear surface 120b of the chip 20. The plurality of terminals 130 (first terminal 131 to fifth terminal 135) are disposed in the first region R1 of the-X axis of the chip 20. The first region R1 is located on the-X axis side of the chip such that the terminals on the chip 20 are compactly arranged, and the fifth terminal 135, which transmits a ground signal, and the communication terminals (the first terminal 131 to the fourth terminal 134), which transmit signals having a high level, are distributed on different surfaces of the chip 20 such that the possibility of a short circuit therebetween is reduced, and electromagnetic interference therebetween is avoided.

The third embodiment is also different from the third embodiment in that the connector 70 according to the present embodiment is an integrally formed member as shown in fig. 45 and 46. The manufacturing material can be a metal section made of low carbon steel or high carbon steel, and nickel plating or chromium plating can be performed on the surface for rust prevention; the raw material of the material can also be a metal section made of stainless steel.

The cross-section of the connector 70 may be circular, oval, rectangular, square, trapezoidal, etc. The production process may be thermoforming or cold forming. The conductive member as shown in fig. 45 is manufactured by a process of thermally deforming a wire having a diameter of 0.6mm, which is made of 82B high carbon steel surface-plated with nickel, for example, by a spring machine. The present embodiment is not limited in terms of the material, the profile, the production process, and the like of the conductive member, as long as stable transmission of the ground signal can be ensured.

For example, if the section of the profile is circular, it may be a wire with a diameter of 0.3-2.5mm, preferably a wire with a diameter of 0.5-1.0mm of the conducting member, and the elasticity of the wire, the stability of the shape are all required. If the cross-sectional diameter of the wire is small, the original shape may not be stably maintained, so that the original shape may not be maintained after the ink cartridge 10 is mounted for a plurality of times, thereby affecting the smooth transmission of the grounding signal. If the wire diameter is large, a jam may occur during the installation or removal of the ink cartridge 10.

If a non-round wire, a metal profile with a width in the range of 0.3-2.5mm may be selected, preferably a metal profile with a width in the range of 0.5-1.0mm is selected for the conducting member. If the shape is a model in which the diameter is circular, elliptical, or the like and the surface of the body is circular arc-shaped, a contact plane (at a position where a broken line of fig. 45 is located) may be ground at the position of the fourth portion 704 so that a portion connected to the +z-axis lower face 96a of the metal piece 96 becomes the first contact portion 70a.

The contact plane 70a' may be ground about the original first contact portion 70a, and specifically, a facet may be ground on a grinder (e.g., at a position where a dotted line of fig. 45 is located), so that a portion functioning as a connection with the metal piece 96 becomes the first contact portion 70a. Because the contact between the connecting piece 70 and the metal piece 96 is plane contact rather than point contact, the influence of vibration generated during the working process of the printer and external vibration on the contact stability of the connecting piece 70 (corresponding to the conducting member of the first embodiment) and the metal piece 96 can be reduced, which is beneficial to improving the contact stability and the stable transmission of the grounding signal. The contact plane 70a' may be a small plane extruded from the original first contact portion 70a, and may be referred to as a first contact portion 70a.

The connector 70 in the present embodiment includes: the first contact portion 70a, the second contact portion 70b, the semi-closed ring 70c, the first bending space 70d, the second bending space 70e, the third bending space 70f, and the fourth bending space 70g. The connecting member 70 is divided into a first part 701, a second part 702, a third part 703, a fourth part 704, a fifth part 705, a sixth part 706, a seventh part 707, an eighth part 708, a ninth part 709, a tenth part 710, and an eleventh part 711 in order according to the bending condition of the profile.

The second portion 702, the fourth portion 704, the sixth portion 706, the seventh portion 707, the eighth portion 708, and the tenth portion 710 are bending regions. The first contact portion 70a is located on the fourth portion 704, and the first contact portion 70a is located at an end position of the connecting member 70 in the-Z direction as viewed in the Z-axis direction, and abuts against the +z-axis lower surface 96a of the metal member 96. The first contact portion 70a is located in the-Z axis direction of the second contact portion 70 b.

The fourth portion 704 is located on the-Z axis side relative to the other portions of the connector 70. The semi-closed ring 70c is located at the-Y axis side of the connection member 70, and the semi-closed ring 70c is a space formed by the first portion 701, the second portion 702, the third portion 703, the fourth portion 704, and the fifth portion 705. The third portion 703 and the fifth portion 705 are different in inclination direction, and the third portion 703 is inclined toward the-Z axis direction when viewed along the Y axis direction, and the fifth portion 705 is inclined toward the +z axis direction.

That is, the third portion 703 is inclined toward the +y-axis and the-Z-axis, and the fifth portion 705 is inclined toward the +y-axis and the +z-axis. The third portion 703, the fourth portion 704, and the fifth portion 705 together form a peak shape, and the fourth portion 704 is located on the most-Z-axis side. At least a part of the fifth portion 705 is located on the-Z axis direction side of the sixth portion 706 to the eleventh portion 711.

When the ink cartridge 10 is mounted to the mounting portion 90, the fifth portion 705 will contact the metal piece 96 first (while if a mounting portion protecting member is provided in the printer in the-Y axis direction of the metal piece 96, the fifth portion 705 will contact the mounting portion protecting member first, and after passing over the mounting portion protecting member, the fifth portion 705 will contact the metal piece 96), and as the ink cartridge 10 is continuously loaded in the mounting direction D2, the-X axis side of the connecting member 70 and the semi-closed ring 70c will be compressed to deform to some extent until the whole of the connecting member 70 enters the mounting portion 90, at which time the first contact portion 70a abuts against the lower face 96a of the metal piece 96. In the above-described mounting process, the fifth portion 705 functions to guide the attachment of the connecting member 70 to the mounting portion 90 and to guide the deformation of the connecting member 70, and eventually the abutment of the first contact portion 70a with the metal member 96 is completed.

When the ink cartridge 10 is to be detached from the mounting portion 90, the first contact portion 70a does not detach from the metal piece 96 when the chip 20 is detached from the stylus assembly 91 of the printer, and when the ink cartridge 10 is to be completely detached from the mounting portion 90, the first contact portion 70a does detach from the metal piece 96.

Further, before the first contact portion 70a is separated from the metal member 96, the third portion 703 may perform guiding and buffering functions as the ink cartridge 10 is continuously removed along a direction opposite to the mounting direction D2, so that the protection component of the connecting member 70, which may be stuck to the metal member 96 during the process of separating the ink cartridge 10 from the mounting portion 90, is avoided, and finally the ink cartridge 10 may be smoothly removed.

So configured, when the ink cartridge 10 is detached from the mounting portion 90, the connection member 70 is restored to the original state by the own elastic force. The connector 70 has an initial state (when the connector 70 is not yet mounted to the mounting portion 90), and an abutting state (when the connector 70 is mounted to the mounting portion 90), which facilitates better contact of the connector 70 with the metal piece 96, and reduces occurrence of unstable contact.

The seventh portion 707 and the eighth portion 708 are both bent into a U-shaped structure with an opening facing the +z axis direction, and can be joined to the first edge 403 and the second edge 404 on the ink supply head 40 to fix the conductive member, so that the connector 70 can bear the pressure of the metal member 96 on the-Y axis side portion of the conductive member 70 and the pressure of the chip 20 on the second contact portion 70b, and the elastic restoring force of the connector 70 can be ensured, and the switching between the initial state and the abutting state of the connector 70 can be ensured.

A third bending space 70f of a U-shaped structure, which opens in the-Z axis direction, is formed between the seventh portion 707 and the eighth portion 708. Some movable buckles may be disposed on the ink supply head 40, and the movable buckles are snapped onto the third bending space 70f, so as to prevent the connector 70 from being separated from the ink supply head 40.

The second contact portion 70b is formed on the tenth portion 710, the second contact portion 70b abuts against the fifth terminal 135 of the chip 20, and the chip 20 gives a certain pressure to the second contact portion 70b, so that the second contact portion 70b is better contacted with the fifth terminal 135. The tenth portion 710 may be ground with a facet at the point of the bend to form a second contact, thereby allowing for a more stable contact of the connector 70 with the chip 20.

As shown in fig. 43 to 46, the connection member 70 is not shifted in the X-axis direction, i.e., the ink cartridge 10 is viewed in the-Y-axis direction, and the projections of the connection member 70 are on the same line perpendicular to the X-axis. Therefore, the projection of the first contact portion 70a onto the chip 20 is located on the fifth terminal 135, the projection of the first contact portion 70a onto the chip 20 is located within the first region R1, and the projection of the first contact portion 70a onto the chip 20 is located on the-X axis position side of the chip 20. The presence of the eleventh portion 711 can prevent the connection member 70 from scratching the fifth terminal 135 during the manufacturing process, avoiding damage to the fifth terminal 135.

As shown in fig. 47 and 48, the ink cartridge 10 further includes: chip mounting portion 201. The chip mounting portion 201 is for carrying the chip 20. The chip 20 is fixed to the ink cartridge 10 by a chip mounting portion 201. The chip mounting section 201 has: through slot 2011, accommodation 2012, plane 2013, positioning post 2014, and fixing 2015.

The planar surface 2013 is attached to the back surface 120b of the chip 20 and is used to position the chip 20. The housing 2012 is for housing the memory 100. The positioning posts 2014 are matched with the first hole-fourth hole of the chip 20, thereby securing the chip 20 to the chip mounting part 201. The connector 70 is abutted against the fifth terminal 135 of the chip 20 through the through groove 2011. As shown in fig. 31, all or at least a part of the ninth section 709, the tenth section 710, and the eleventh section 711 of the connection member 70 is accommodated in the through groove 2011.

The fixing portion 2015 is a protrusion provided on the chip mounting portion 201, and is matched with the fixing groove 451 on the ink supply head 40 to fix the chip mounting portion 201. Some buckles can be arranged on the fixing part 2015 and can be clamped on the fixing groove 451 through the buckles, so that the chip mounting part 201 can be reduced from being separated from the ink supply head 40 under the action of the elastic force of the connecting piece 70.

The ink supply head 40 has an upper surface 40a on the-Z axis side, a protruding portion, and a bearing portion 45. The protrusion is located on the-Y axis side on the upper surface 40 a. The protruding portion may have only the first protruding portion 43 (as shown in fig. 50), or may have the first protruding portion 43 and the second protruding portion 44 (as shown in fig. 50). When the protruding portions include the first protruding portion 43 and the second protruding portion 44, the first protruding portion 43 and the second protruding portion 44 may serve as a pinching portion for a user who mounts the ink cartridge 10 to the tray 97 in the mounting direction D1 or takes out the ink cartridge 10 in a direction opposite to the mounting direction D1, and by pinching the side surfaces of the first protruding portion 43 and the second protruding portion 44, the user can move the ink cartridge 10, facilitating the taking out and mounting of the ink cartridge 10.

The ink supply head 40 further includes: first projection 401, second projection 402, first rib 403, second rib 404, and fixing groove 451. The fixing groove 451 is used to fix the chip mounting part 201. When the connector 70 is mounted to the ink supply head 40, the first protrusion 401 is located within the semi-closed loop 70c of the connector 70, reducing the occurrence of the connector 70 coming off the ink supply head 40.

The second protrusion 402 is located in the first bending space 70d of the connecting member 70, so as to reduce the occurrence of detachment of the connecting member 70 from the ink supply head 40; the first rib 403 mates with the seventh portion 707, which may be an interference fit, reducing the occurrence of the connector 70 becoming detached from the ink supply head 40; the second rib 404 mates with the eighth portion 708, which may be an interference fit, reducing the occurrence of the connector 70 becoming detached from the ink supply head 40. Some movable buckles may be disposed on the ink supply head 40, and the movable buckles are snapped onto the third bending space 70f, so as to prevent the connector 70 from being separated from the ink supply head 40.

The first projection 401 is provided with an inclined surface 401a on the-Z axis side, the second projection 402 is provided with an inclined surface 402a on the-Z axis side, the first rib 403 is provided with an inclined surface 403a on the-Z axis side, and the second rib 404 is provided with an inclined surface 404a on the-Z axis side, which serves as a guide when the connector 70 is mounted to the ink supply head 40.

Further, as shown in fig. 52, the ink supply head 40 of the ink cartridge 10 of the present embodiment is provided with the widening members 46 at +x-axis side and-X-axis side, which increases the width of the ink cartridge 10 in the X-axis direction, which is advantageous in widening the width of the ink bag 10a, and increasing the ink capacity of the ink bag 10 a. It will also be appreciated that the tray 97 will also widen in the X-axis direction. In the present embodiment, the connector 60 (conductive member) contacts the ground member before the chip 20 contacts the contact pin assembly 91 during the mounting of the ink cartridge 10 to the printing apparatus.

Fourth embodiment of example three:

In a fourth embodiment, the present embodiment provides a ground conductive member on the basis of the above embodiment, wherein one end of the conductive member is electrically connected to a ground terminal of the chip, the other end of the conductive member extends downward and is electrically connected to the conductive swing rod, and the two electrically connected positions are located below the chip and are further connected to the ground component through the conductive swing rod.

Specifically, as shown in fig. 53 and 54, the ink cartridge body 50 further includes a bottom case 51 (corresponding to the ink supply head 40 in the second and third embodiments), at least a part of the connector 70 is provided on the front end side of the front surface 51a in the mounting direction D2 (+y axis direction), and a space Q is formed between the connector 70 (corresponding to the conductive member) and the front surface 51a, the space Q being capable of accommodating a part of the mounting portion 90; at least a portion of the connector 70 is disposed below the bottom surface 51b of the ink cartridge 10.

Further, a portion of the connection member 70 may be accommodated in the space Q. For example, one side of the connection member 70 is provided in an "n" shape, and a part of the connection member 70 is also provided in the space Q. As shown in fig. 56, the connector 70 further includes an extension 710, the extension 710 being disposed in the space Q between the space Q and the front surface 51 a. With this structure, the space Q is still provided between the connection member 70 and the front surface 51 a. As long as a portion of the connection member 70 meets this description, it is a feature that the space Q is formed between the connection member 70 and the front surface 51 a.

The space Q is limited by the front wall 97aa, and the conductive member itself contacts the ground member. Further, the bottom of the accommodating chamber has a bottom wall 97bb, and the grounding member may be the bottom wall 97bb of the accommodating chamber.

With continued reference to fig. 53-56, one portion of the connector 70 is connected to the chip 20 and another portion is connected to the ground member of the mounting portion 90. The connector 70 serves as both a mechanical means and a chip signal detection means to ensure proper mounting of the cartridge to the mounting portion 90 of the printer.

The space Q between the connector 70 and the front surface is adapted to mate with the front wall 97aa of the tray 97, and the tray 97 is installed in position with the ink cartridge 10 only if the front wall 97aa enters the space Q.

Further, the ink cartridge 10 includes the chip 20, the bottom case 51, the ink bag 10a, the connector 70, the hole portions 220 and 210, the front surface 51a in the +y axis direction, the bottom surface 51b in the +z axis direction, and the ink outlet 41. Tray 97 has a front wall 97aa, and positioning holes 971 and 972.

The locking portion 94 has an upper surface 94a in the-Z axis direction. When the ink cartridge 10 is mounted on the mounting portion 90, the ink supply portion 92 (ink supply tube) is matched with the ink outlet 41, and ink can be supplied for printing by the printer.

In the embodiment of the application, part of the conductive intermediate film is exposed on the outer surface of the film layer structure and forms the first electric connection part, the first electric connection part can be electrically connected with the first conductive sheet, and the other end of the first conductive sheet is electrically connected with the grounding terminal of the chip. For example, the insulating outer film includes a first hollow portion, the first hollow portion is disposed near the first conductive sheet, and a portion of the conductive intermediate film is exposed to the first hollow portion and forms a first electrical connection portion.

The second electric connection part can be opposite to the first electric connection part and is electrically connected with the grounding part through the unexposed conductive intermediate film.

For example, the insulating outer film comprises a second hollow part, at least part of the conductive intermediate film is exposed in the second hollow part and forms a second electric connection part, and the second electric connection part is electrically connected with the first electric connection part through part of the conductive intermediate film so as to transmit a grounding signal; that is, the ground signal between the chip and the printer is transmitted through the first conductive sheet, the intermediate conductive film, and the ground member. By the arrangement, the grounding stability of the ink box is improved, and the situations that the ink box cannot be grounded or is unstable in grounding are reduced.

In addition to the above-described embodiment, the grounding member in this embodiment may be an outer frame (+z-axis, -Z-axis, +x-axis, -X-axis, +y-axis direction outer frame) of the mounting portion 90 or a part of the outer frame, for example, a cavity wall forming the accommodating cavity as the grounding member, the first electric connection portion being located on the Y-axis side of the ink bag 10a, the second electric connection portion being located on the-Y-axis side of the ink bag, and the second electric connection portion being located on the-Z-axis side of the first electric connection portion, that is, the second electric connection portion being located closer to the cavity wall of the accommodating cavity than the first electric connection portion.

The film layer structure of the partial area of the surface of the ink bag 10a has four layers of films: the first film is made of PET along the direction from the outside to the inside of the ink bag 10a, so the first film is also called PET film, i.e., insulating outer film; the second layer of film is made of Al and can conduct electricity, and is also called an aluminum film, a metal film or an intermediate conductive film 10a1; the third layer of film is nylon film; the fourth film is made of PET140, so the fourth film is also called PET140 film.

The conductive films 10a1 of all areas on the ink bag 10a are connected, that is, the same conductive film 10a1 is present in both the area where three films are provided and the area where four films are provided on the ink bag 10 a. Meanwhile, the conductive film 10a1 is isolated from the ink stored in the ink bag 10a, so that the ink does not participate in the transmission of the grounding signal in this scheme.

In the embodiment of the present application, a part of the first conductive sheet 71 is connected to the chip 20, and the other part is connected to the conductive film (first electrical connection portion) of the conductive area a of the ink bag 10 a. The first conductive sheet 71 has a first portion 71a and a second portion 71b. The first portion 71a is connected to the chip 20, and the second portion 71b is connected to the conductive film.

As shown in fig. 59, the-Y-axis side end portion of the ink bag 40 in the present embodiment extends in the-Z-axis direction, the-Z-axis side surface of the end portion has a conductive region B which is a second electrical connection portion, the conductive film 10a1 of the conductive region B is connected to the metal piece 96 of the +z-axis side outer frame body of the mounting portion 90, and the metal piece 96 is a cavity wall forming a housing cavity, thereby realizing transmission of the ground signal between the chip 20 and the printer 1.

The conductive region may be provided at any place of the ink bag 10a, and the conductive film in the region may be connected to the metal piece 96 of the mounting portion 90, for example, the conductive film at the +y-axis side position, the +x-axis side, -X-axis side, -Z-axis side, or the +z-axis side position of the ink bag 10a may be connected to the metal piece 96 of the mounting portion 90, except for the-Y-axis side end of the ink bag 10 a.

Optionally, after the conductive film of the conductive area C is connected to the second conductive sheet 72, the-Z axis side of the connection between the two is covered with a PET film, so that the appearance of the ink cartridge 10 is more attractive, or the connection between the two is fixed by an adhesive member (such as an adhesive tape) so that the connection between the second conductive sheet 72 and the conductive film 10a1 is more stable.

In the above-described aspect, the metal piece of the mounting portion 90 may be an outer frame (+z-axis, -Z-axis, +x-axis, -X-axis, +y-axis direction) of the mounting portion 90 or a part of the outer frame. For user safety, the hardware of the mounting portion 90 is grounded and the ground signal between the printer and the mounting portion is communicated.

In this embodiment, the second conductive sheet 72 extends from the conductive region C of the ink bag 10a in the-Z axis direction, extends to the-X axis side or the +x axis side until it passes over the tray 97, and extends in the +z axis direction and is connected to the outer frame of the mounting portion 90 on the +z axis side.

The number of the second conductive pieces 72 is not limited, and one or a plurality of pieces may be provided, for example, and the positions thereof provided on the ink bag 10a are not limited, and may be provided on the upper surface or the lower surface of the ink bag 10a, for example, on the +x-axis side, -X-axis side, +y-axis side, or-Y-axis side of the ink bag 10 a. Sixth embodiment of example three:

Fig. 62 is a schematic view of an ink cartridge according to a sixth embodiment of the third embodiment of the present application. The description of the ink cartridge in this embodiment is identical to that of the fourth embodiment of the third embodiment, and the chip uses the first modification of the chip or the third modification of the chip, which is not described herein again.

Seventh embodiment of the third embodiment:

Accordingly, the conductive member includes a bridging portion such that the conductive member passes over the barrier plate 85, i.e., the bridging portion spans over the barrier plate 85, and a portion of the bridging portion adjacent to the conductive strip is capable of contacting and electrically connecting with the conductive strip.

As shown in fig. 66, rail 86 may be a conductive member that carries a ground signal and may or may not be a non-conductive member that carries a ground signal. When the rail 86 carries a ground signal, the conductive support plate 82 may be a part of the rail, or the rail 86 and the conductive support plate 82 may be 2 different components. The barrier 85 is a non-conductive component that does not carry a ground signal (e.g., the barrier 85 is made of non-conductive plastic), so the conductive member in this embodiment must span the barrier 85 to abut the conductive support 82.

Specifically, as shown in fig. 64 and 65, in the present embodiment, the chip 20 is disposed at the front end side of the mounting direction of the ink cartridge 10, the memory 100 is disposed on the rear surface 120b of the chip 20, a conductive sheet 140a is further disposed between the chip 20 and the ink cartridge 10, the conductive sheet 140a is substantially identical in shape to the chip 20, an opening 111 is provided in the middle of the conductive sheet 140a, which is identical in shape to the memory 100, the opening 111 is sized to just accommodate the passage of the protruding portion of the memory 100, and the ground terminals 137a, 137b are bonded to the conductive sheet 140a after the chip 20 and the conductive sheet 140a are mounted.
