Detailed Description

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

The technical scheme disclosed by each embodiment of the utility model is described in detail below with reference to the accompanying drawings.

Printing consumables are necessary components of printing equipment, such as ink cartridges, selenium drums and the like. In order to record the service condition of the printing consumable installed on the printing equipment, the printing consumable comprises a consumable chip, the original consumable chip on the printing consumable is called an original chip, and data required for printing are stored in a storage element in the original chip. The original chip comprises a first substrate, a plurality of functional terminals and an original storage element, wherein the functional terminals and the original storage element are arranged on the first substrate, when the printing consumable is in a use state, namely when ink or toner is still in the printing consumable, the printing equipment is communicated with the original storage element through at least one of the functional terminals, so that the printing equipment reads information in the original storage element, and the printing consumable is identified. However, when the ink within the printing consumable is exhausted, the printing consumable is typically out of order, i.e., the printing consumable cannot be reinstalled into the printing apparatus for use whether or not it is refilled with ink or toner. The grafting chip disclosed by the application can enable the printing consumable to be identified by the printing equipment again, thereby realizing the regeneration of the printing consumable.

As shown in fig. 1 to 11, an embodiment of the present utility model discloses a grafting chip 120, and the grafting chip 120 is applied to printing consumables. The disclosed grafted chip 120 includes a second substrate 121 and a grafted storage element 122 disposed on the second substrate 121, and the first substrate 111 is stacked with the second substrate 121. At this time, the grafting chip 120 is attached to the original chip 110.

Wherein at least two functional terminals 112 among the plurality of functional terminals 112 on the original chip 110 are electrically connected to each other. One of the at least two functional terminals 112 electrically connected to each other is for electrical connection with the graft storage element 122, and the other is for electrical connection with a printing apparatus adapted to a printing consumable. The functional terminals 112 electrically connected to the printing apparatus may be directly in contact with the contact pins of the printing apparatus, or may be indirectly electrically connected to the contact pins of the printing apparatus through a circuit structure provided on the second substrate 121.

In a specific data reading process, the data of the printing apparatus is transmitted to one of the functional terminals 112 electrically connected to the corresponding functional terminal, and the functional terminal 112 is further transmitted to the other functional terminal 112 electrically connected to the corresponding functional terminal, and then further transmitted to the graft storage element 122. The data of the printing device is thus transmitted to the graft storage element 122 via at least two functional terminals 112 on the original chip 110, which are electrically connected to one another. Thereby enabling the printing device to read and write data to the graft storage element 122.

At this time, the grafting chip 120 is mounted on the original chip 110, and meanwhile, the grafting chip 120 utilizes a part of line functions of the original chip 110, so that binding of storage elements is realized, and then a new storage element is connected into a printing consumable or a printing consumable chip, so that the printing consumable or the printing consumable chip can be identified again, and regeneration of the printing consumable or the printing consumable chip is realized.

In the embodiment disclosed by the application, the grafting chip 120 utilizes part of the circuit function of the original chip 110, so that the binding of the storage element is realized, and compared with the scheme in the related art, the application can realize the regeneration between the regenerated storage element and the chip substrate with different electric connection relations and metal wiring, thus the compatibility is better, and the regeneration difficulty of printing consumables or printing consumable chips is reduced.

In addition, the technical scheme of the application utilizes part of the circuit functions of the original chip 110, thereby realizing the binding of new storage elements, thus being capable of realizing the cross-generation utilization of the original chip, greatly improving the recycling rate of the original chip, and being capable of reducing the cost of the chip in the printing equipment, and further reducing the cost of the printing equipment.

The embodiment disclosed by the application can also regenerate various chips with different types into chips with expected types, so that the regenerated chips can be compatible with more series of printing equipment, the compatibility of the regenerated chips is improved, and the screening difficulty of the original chips 110 is reduced. For example, the chip of the printing supplies adapted to the printing apparatus is 5 terminals, and when the printing supplies are regenerated, the printing supplies of the 5 terminal chip need to be screened for regeneration, which increases the screening difficulty of the original chip 110 during regeneration. In the technical scheme disclosed by the application, the grafting chip 120 is attached to the original chip 110, so that the chip 120 and the chip which can be designed to be matched with the target printing equipment can be regenerated while the regeneration of printing consumables is realized, and further, the chips with various different types can be regenerated into the chips with expected types, so that the screening difficulty of the original chip 110 is reduced.

Further, the electrical connection between the printing apparatus and the graft storage element 122 of the graft chip 120 is achieved using at least two terminals of any electrical connection of the original chip 110 as conductive wires of the electrical connection of the printing apparatus and the graft chip 120. Therefore, the wiring of the data terminal of the grafting chip 120 can be reduced, so that more space is increased for the functional design of the grafting chip 120, and the regeneration function of printing consumables can be optimized more favorably.

In order to avoid the risk of the printing material not being recognized due to the fact that the printing equipment is connected with the original storage element by mistake. In another alternative embodiment, at least two of the functional terminals 112 electrically connected to each other may each be disconnected from the original storage element. In this solution, at least two functional terminals 112 electrically connected to each other are all disconnected from the original storage element, so that conduction between the printing device and the original storage element can be avoided, and further, the reliability of printing consumable reproduction is improved.

In the above embodiment, at least two functional terminals 112 electrically connected to each other may be originally connected to each other, that is, at least two functional terminals 112 electrically connected to each other are present on the original chip 110 itself. For example, taking the original chip 110 as a 9-terminal chip, two short-circuit detection terminals in the 9-terminal chip are conducted with each other. Or at least two functional terminals 112 electrically connected to each other after the original chip 110 is modified, for example, no electrical connection exists between the functional terminal No. 4 and the functional terminal No. 9 in fig. 1 of the present application, and conductive structures such as wires and conductive sheets may be welded between the functional terminal No. 4 and the functional terminal No. 9, so that the functional terminal No. 4 and the functional terminal No. 9 are electrically conducted. In this way, at least two non-conductive functional terminals 112 of the original chip 110 are modified so that the at least two functional terminals 112 are conductive to each other.

In another alternative, at least two of the functional terminals 112 electrically connected to each other may each be a short detection terminal. Taking the original chip 110 as a 9-terminal chip as an example, as shown in fig. 1, the No. 1 functional terminal is a short circuit detection terminal, the No. 2 terminal is a reset terminal, the No. 3 functional terminal is a clock data terminal, the No. 4 functional terminal is a short circuit detection terminal, the No. 5 functional terminal is a mounting detection terminal, the No. 6 functional terminal is a power supply terminal, the No. 7 functional terminal is a ground terminal, the No. 8 functional terminal is a data terminal, and the No. 9 functional terminal is a mounting detection terminal. Since the two short-circuit detection terminals No. 1 and No. 4 are electrically connected, and both the two short-circuit detection terminals No. 1 and No. 4 are disconnected from the original storage element of the original chip 110, the two short-circuit detection terminals No. 1 and No. 4 can be preferentially selected to communicate with the grafting storage element 122 and the printing apparatus.

In another alternative, the mounting detection terminals No. 5 and No. 9 are disconnected from the original storage element of the original chip 110, so that the functional terminals No. 5 and No. 9 can also be selected to communicate with the grafting storage element 122 and the printing apparatus. It should be noted that other components such as a resistor may be provided between the functional terminal No. 5 and the functional terminal No. 9, so that the functional terminal No. 5 and the functional terminal No. 9 are conducted, and the original chip 110 needs to be modified, so that the functional terminal No. 5 and the functional terminal No. 9 are conducted.

The scheme disclosed by the application can select at least two of the functional terminals No. 1, no. 4, no. 5 and No. 9 to be communicated with the grafting storage element 122 and the printing equipment.

In another alternative embodiment, the grafted chip 120 may further include a plurality of connection pins 123, and the plurality of connection pins 123 may be located on a surface of the second substrate 121 facing the side of the first substrate 111. At this time, the connection pin 123 is disposed opposite to the functional terminal 112.

At least one connection pin 123 of the plurality of connection pins 123 is electrically connected with the graft storage element 122 through a circuit structure provided on the second substrate 121; at least two functional terminals 112 electrically connected to each other communicate with the graft storage member 122 through at least one connection pin 123.

In this solution, the surface of the side of the grafting chip 120 facing the original chip 110 is provided with the connection pins 123, so that the electrical connection and the physical connection between the grafting chip 120 and the original chip 110 are conveniently realized. At this time, the connection pins 123 can realize both electrical connection and physical connection, and the physical connection refers to a fixed connection between two members. Therefore, the attaching structure of the grafting chip 120 and the original chip 110 can be simplified, so that the structure of the grafting chip 120 is simpler. At the same time, the line structure of the grafted chip 120 can be optimized.

At least one connection pin 123 of the above embodiment and the graft storage member 122 may be electrically connected through a circuit structure etched or deposited on the second substrate 121.

The grafted chip 120 disclosed by the application has various structures, and the assembly structures of the other original chips 110 are different due to the different structures of the grafted chip 120, so that the matching structures of the connection pins 123 and the functional terminals 112 are also different.

In an alternative embodiment, as shown in fig. 1 and 2, the plurality of connection pins 123 may include a first connection pin 123a and a second connection pin 123b, respectively. The second connection pin 123b is electrically connected to the grafted storage element 122 through a circuit structure disposed on the second substrate 121.

One of the at least two functional terminals 112 electrically connected to each other is disposed opposite to the first connection pin 123a and electrically connected thereto, and the other is disposed opposite to the second connection pin 123b and electrically connected thereto. Here, it is understood that the functional terminal 112 electrically connected to the first connection pin 123a is a first functional terminal 112a, and the functional terminal 112 corresponding to the second connection pin 123b is a second functional terminal 112b. As shown in fig. 1, the connection pin a is electrically connected with the functional terminal No. 4. The D-shaped connecting pin is electrically connected with the No. 1 functional terminal.

As shown in fig. 2, the grafted chip 120 further includes a plurality of printing contacts 124, and the plurality of printing contacts 124 may be located on a surface of the second substrate 121 on a side facing away from the first substrate 111. The second substrate 121 may include a front surface and a rear surface disposed opposite to each other, the printing contact 124 may be disposed on the front surface, and the connection pin 123 may be disposed on the rear surface. The front side is also understood here to mean the side facing away from the original chip 110 and the rear side the side facing toward the original chip 110.

The first connection pin 123a may be electrically connected to at least one printing contact 124 through a circuit structure disposed on the second substrate 121, and specifically, the first connection pin 123a and its corresponding printing contact 124 may be electrically connected through a via hole disposed on the second substrate 121. The print contact 124 is for direct electrical connection with a printing device. The stylus of the printing device can now be brought into direct contact with the printing contact 124.

In a specific data transmission process, the printing device is conducted with the printing contacts 124 through the contact pins, specifically, one of the printing contacts 124 corresponding to the first connection pin 123a is conducted, such as the printing contact 10 in fig. 2. At this time, the data of the printing apparatus is transferred to the print contact No. 10 through the stylus thereof, and then transferred to the first connection pin 123a (connection pin No. D) through the via hole on the second substrate 121 by the print contact No. 10. The first connection pin 123a is then transmitted to the first functional terminal 112a (functional terminal No. 1), the first functional terminal 112a is then transmitted to the second functional terminal 112b (functional terminal No. 4), and the second connection pin 123b is finally transmitted to the graft storage element 122.

The scheme utilizes two functional terminals 112 which are arbitrarily and directly electrically connected with the original chip 110 as conductive wires between the printing contact 124 of the grafting chip 120 and the grafting storage element 122 of the grafting chip 120, so that the electrical connection between the printing contact 124 of the grafting chip 120 and the grafting storage element 122 of the grafting chip 120 is realized, and further, the electrical connection between the printing equipment and the grafting storage element 122 is realized.

In this scheme, the printing contacts 124 serve as direct connection positions for data transmission between the grafted chip 120 and the printing device, wherein one printing contact 124 is electrically connected with the grafted storage element 122 through the corresponding connection pin 123 and the corresponding functional terminal 112, and at this time, the printing contact 124 of the grafted chip 120 is not limited by the original chip 110, so that multiple original chips 110 with different types can be regenerated into chips with desired types, and therefore, the difficulty of screening the original chips 110 during regeneration is further reduced.

Further, the plurality of print contacts 124 may include a data contact, a reset contact, a clock contact, a power contact, and a ground contact, respectively. The data contact may be electrically connected to the first connection pin 123a through a circuit structure disposed on the second substrate 121. The reset contact, clock contact, power contact, and ground contact may all be electrically connected to the graft storage element 122 through circuit structures disposed on the second substrate 121. At this time, the data contacts are electrically connected to the graft storage member 122 through a part of the circuit structure of the original chip 110, and the remaining printing contacts 124 are directly electrically connected to the graft storage member 122 through the circuit structure on the second substrate 121.

This approach utilizes both the circuit structure of part of the original chip 110 and the space on the second substrate 121, thereby further optimizing the circuit layout of the grafted chip 120.

The grafting chip 120 may be a 5-terminal chip, where 5-terminal refers to the number of points at which the grafting chip 120 may form contact with a printing stylus. As shown in fig. 2, the print contacts No. 10 to No. 14 are a data contact, a reset contact, a clock contact, a power contact, and a ground contact, respectively. The specific function of each print contact 124 is common general knowledge and will not be described in detail herein. The original chip 110 may be a 9-terminal chip. The connection pins 123 on the corresponding grafted chip 120 may also be 9 connection pins 123. The specific names of the 9 functional terminals 112 on the original chip 110 have been mentioned above, and will not be described here again.

In a specific embodiment, as shown in fig. 1 and 2, the print contact No. 10 and the connection pin No. D are electrically connected through a via on the second substrate 121. Because the D connection pin is opposite to the No. 1 functional pin, the D connection pin can be electrically connected with the No. 1 functional pin. Because the electric connection between the No. 1 functional pin and the No. 4 functional pin is the electric connection and the circuit breaking with the original storage element, the electric connection requirement is met, and the No. 4 functional terminal is electrically connected with the opposite A connecting pin. The connection pin a may be directly electrically connected to the graft storage element 122. At this time, the 9-terminal chip of the original chip 110 is regenerated into the 5-terminal chip of the graft chip 120.

In addition, in order to improve the connection strength between the grafting chip 120 and the original chip 110, the B connection pin, the C connection pin, the E connection pin, the F connection pin, the G connection pin, the H connection pin, and the I connection pin of the grafting chip 120 may be physically connected with the 2 nd functional terminal, the 3 rd functional terminal, the 5 th functional terminal, the 6 th functional terminal, the 7 th functional terminal, the 8 th functional terminal, and the 9 th functional terminal of the original chip 110, respectively, that is, only fixedly connected, not electrically connected, and thus non-conductive.

In another alternative embodiment, as shown in fig. 5 and 6, at least one connection pin 123 is a third connection pin 123c, and the third connection pin 123c may be electrically connected to the graft storage element 122 through a circuit structure disposed on the second substrate 121. The second substrate 121 may be provided with a clearance hole 128 disposed in parallel with the third connection pin 123 c.

The at least two functional terminals 112 electrically connected to each other include a first functional terminal 112a and a second functional terminal 112b, and the second functional terminal 112b is disposed opposite to the third connection pin 123c and is electrically connected. The first functional terminal 112a is disposed opposite the clearance hole 128 and is configured for direct electrical connection with the printing device, where a direct electrical connection is understood to mean that a stylus of the printing device may directly contact the first functional terminal 112 a.

At this time, the third connection pin 123c in fig. 5 corresponds to the second connection pin 123b in fig. 1 in comparison with the schemes in fig. 1 and 2. The first connection pin 123a in fig. 1 is hollowed out to form a clearance hole 128, thereby exposing the first functional terminal 112a (functional terminal No. 1). It is also understood that the print contact No. 10 is hollowed out so that the functional terminal No. 1 opposite the print contact No. 10 acts as the print contact No. 10.

In a specific data transmission process, the data of the printing device is transmitted from the first functional terminal 112a to the second functional terminal 112b, then transmitted from the second functional terminal 112b to the third connection pin 123c, and then transmitted from the third connection pin 123c to the grafting storage element 122.

In this solution, the area of the second substrate 121 corresponding to the first functional terminal 112a is hollowed, so that the first functional terminal 112a on the original chip 110 is made to be a data contact of the grafted chip 120 and directly contacts with a contact pin of the printing device to form an electrical connection, so that the risk of unstable signal transmission or incapability of transmitting data due to unqualified welding between the terminal and the pin can be avoided, and the regeneration yield is improved. Meanwhile, wiring of data contacts of the grafting chip 120 is reduced, so that more space is provided for design of the grafting chip 120.

In addition, the first functional terminal 112a and the avoidance hole 128 are disposed opposite to each other, and at this time, the avoidance hole 128 and the first functional terminal 112a can be used as positioning components of the original chip 110 and the grafted chip 120, so as to achieve the attaching precision between the original chip 110 and the grafted chip 120.

Further, as shown in fig. 6, the front surface of the second substrate 121 further has No. 11 to No. 14 printing contacts 124, where the No. 11 to No. 14 printing contacts 124 may be electrically connected to the graft storage element 122 through a circuit structure on the second substrate 121.

In another alternative embodiment, as shown in fig. 7, 9 and 10, the plurality of connection pins 123 may be respectively comprised of a fourth connection pin 123d and a fifth connection pin 123e, and the fourth connection pin 123d is electrically connected to the graft storage element 122 through a circuit structure provided on the second substrate 121. The at least two functional terminals 112 electrically connected to each other may include a third functional terminal 1121, a fourth functional terminal 1122, and a fifth functional terminal 1123, respectively. The fifth functional terminal 1123 may be electrically connected to the fourth functional terminal 1122, and the third functional terminal 1121 may be electrically connected to the fourth functional terminal 1122.

A gap 125 is formed in the second substrate 121 in a region opposite to the fifth functional terminal 1123. The mounting detection terminal is used for being directly and electrically connected with the printing equipment. The fourth connection pin 123d is opposite to the fourth functional terminal 1122 and is electrically connected. The fifth connection pin 123e is opposite to the third functional terminal 1121.

The grafting chip 120 may further include a plurality of printing contacts 124, where the plurality of printing contacts 124 may be located on a surface of the second substrate 121 facing away from the first substrate 111, and the plurality of printing contacts 124 may be electrically connected to the grafting storage element 122 through a circuit structure disposed on the second substrate 121.

In this solution, the area of the second substrate 121 corresponding to the fifth functional terminal 1123 is hollowed, so that the fifth functional terminal 1123 on the original chip 110 is formed by directly contacting the contact point of the grafting chip 120 with the contact pin of the printing device to form an electrical connection, so that the risk of unstable signal transmission or incapability of transmitting data due to unqualified welding between the terminal and the pin can be avoided, and the regeneration yield is improved. Meanwhile, wiring of data contacts of the grafting chip 120 is reduced, so that more space is provided for design of the grafting chip 120.

In addition, since the grafting chip 120 is provided with the clearance gap 125, the grafting chip 120 can be adjusted in an inclined position when being attached to the original chip 110, so that the grafting chip 120 is more tightly connected with the original chip 110, and the risk of virtual connection of the connection point is not easy to occur.

The above-described arrangement differs in the location of the mounting of the detection terminals and the location of the clearance gap 125 in different embodiments. The present application discloses several specific structures, but is not limited to the specific structures of the present application.

As shown in fig. 7, the fifth functional terminal 1123 herein may be a functional terminal No. 9. In this case, in order to facilitate the electrical connection between the fifth functional terminal 1123 and the fourth functional terminal 1122, the functional terminal No. 4, which is located at a relatively short distance from the functional terminal No. 9, is preferentially selected as the fourth functional terminal 1122, and thus the functional terminal No. 1 is the third functional terminal 1121. At this time, the area of the grafted chip 120 corresponding to the functional terminal No. 9 is hollowed out, and the area of the grafted chip corresponding to the functional terminal No. 9 is left empty because the area corresponding to the functional terminal No. 9 is a ground contact. The functional terminal No. 9 can be defined as a ground contact in this scheme. The contact pins of the printing apparatus may be in direct contact with functional terminals No. 9. The data of the printing apparatus sequentially passes through the functional terminal No. 9, the functional terminal No. 4, and the connection pin a and then is transmitted to the graft storage element 122. In the scheme shown in fig. 7, although the functional terminal No. 1 and the functional terminal No. 4 are electrically connected, they are short-circuited by the functional terminal No. 9, and thus do not affect data transmission. In the scheme shown in fig. 7, the D connection pin may be electrically connected to the functional terminal No. 1, or may be not electrically connected, and only physically connected. In the scheme shown in fig. 7, the printing contacts 124 on the grafting chip 120 are all in communication with the grafting storage element 122 through the circuit structure on the second substrate 121.

As shown in fig. 9, the fifth functional terminal 1123 herein may be a functional terminal No. 5. In this case, in order to facilitate the electrical connection between the fifth functional terminal 1123 and the fourth functional terminal 1122, the functional terminal No. 1 located at a relatively short distance from the functional terminal No. 5 is preferentially selected as the fourth functional terminal 1122, and thus the functional terminal No. 4 is the third functional terminal 1121. At this time, the area of the grafted chip 120 corresponding to the functional terminal No. 5 is hollowed out, and the area of the clock contact in the scheme of fig. 9 is left empty because the area corresponding to the functional terminal No. 5 is the clock contact. The functional terminal number 5 may be defined as a clock contact in this scenario. The contact pins of the printing apparatus may be in direct contact with functional terminals No. 5. The data of the printing apparatus sequentially passes through the functional terminal No. 5, the functional terminal No. 1, and the D connection pin and then is transmitted to the graft storage element 122. In the scheme shown in fig. 9, although the functional terminal No. 1 and the functional terminal No. 4 are electrically connected, they are short-circuited by the functional terminal No. 5, and thus data transmission is not affected. In the scheme shown in fig. 9, the connection pin a may be electrically connected to the functional terminal No. 4, or may be not electrically connected, and only physical connection is performed. In the solution shown in fig. 9, the printing contacts 124 on the grafting chip 120 are all in communication with the grafting storage element 122 through the circuit structure on the second substrate 121.

As shown in fig. 10, the fifth functional terminal 1123 herein may be a functional terminal No. 5. In this case, the functional terminal No. 1 may be the third functional terminal 1121,4 and the functional terminal No. 1122 may be the fourth functional terminal. At this time, the area of the grafted chip 120 corresponding to the functional terminal No. 5 is hollowed out, and the area of the clock contact in the scheme of fig. 10 is left empty because the area corresponding to the functional terminal No. 5 is the clock contact. The functional terminal number 5 may be defined as a clock contact in this scenario. The contact pins of the printing apparatus may be in direct contact with functional terminals No. 5. The data of the printing apparatus is sequentially transmitted to the graft storage element 122 after passing through the functional terminal No. 5, the functional terminal No. 1, the functional terminal No. 4, and the connection pin a. In the scheme shown in fig. 10. In the scheme shown in fig. 10, the D connection pin may be electrically connected to the functional terminal No. 1, or may be not electrically connected, and only physically connected. In the scheme shown in fig. 10, the printing contacts 124 on the grafting chip 120 are all in communication with the grafting storage element 122 through the circuit structure on the second substrate 121.

In the above-described embodiment, no matter where the printing contact 124 is cut off on the graft chip 120, the functional terminal 112 of the area of the original chip 110 corresponding thereto can replace the printing contact 124 cut off thereat, so that the graft chip 120 or the combination of the graft chip 120 and the original chip 110 can still provide five contact portions that are in contact with the printer stylus. In the arrangements shown in fig. 2-4, 6, 8, 11, etc., the regenerated chip can eventually still provide 5 printed contacts 124, thus regenerating a 5-contact chip.

In the above embodiment, in the use process of the printing consumable, the conductive material such as ink or toner is easily attached to the front surface of the grafted chip 120, that is, the surface of the side provided with the printing contacts 124, so that any two printing contacts 124 are easily conducted, thereby causing the contact short circuit of the chip and further causing the damage of the printing device.

Based on this, in another alternative embodiment, at least one ground contact and a plurality of functional contacts may be included in the plurality of print contacts 124. Specifically, the ground contact is a print contact No. 14, and print contacts No. 10 to 13 124 are functional contacts. The second substrate 121 may further be provided with a detection wire 126 on a side facing away from the first substrate 111, the detection wire 126 may be electrically connected to the ground contact, and the detection wire 126 may be provided between any adjacent two functional contacts.

In this scheme, when the conductive material such as ink, toner or the like is conducted to any two functional contacts and covers the detection wire 126, the detection wire 126 is caused to be shorted, so that an abnormal voltage generated by the short circuit is led to the grounding contact, and the printing device and the chip cannot keep normal communication, so that the printing device reports errors, and the risk of damaging the printing device can be avoided.

The structures of the detecting wire 126 shown in fig. 2, 3 and 4 of the present application are just examples, but other structures are possible and are not limited herein. In the scheme shown in fig. 8, the functional terminal No. 9 of the original chip 110 may be defined as a ground contact of the grafted chip 120, and in order to facilitate the electrical connection between the detection wire 126 and the ground contact, a portion of the detection wire 126 extends from the front surface of the second substrate 121 to the back surface of the second substrate 121, where a portion of the detection wire 120 extending to the back surface may be electrically connected to at least one of the connection pin No. a or the connection pin No. D. Alternatively, as shown in fig. 7 to 8, when the portion of the detection wire 126 extending to the rear surface is electrically connected to the connection pin a, the detection wire 126 is electrically connected to the functional terminal No. 9 through the connection pin a. Or when the portion of the detection wire 126 extending to the back is electrically connected to the D-connection pin, the detection wire 126 is electrically connected to the 9-functional terminal through the D-connection pin, the 1-functional terminal, and the 4-functional terminal in this order.

Alternatively, the detecting wire 126 may be disposed on the second substrate 121 by plating, etching, photolithography, or the like, and of course, the detecting wire 126 may be fabricated by other methods, which is not limited herein.

In addition, the existence of the avoidance hole 128 and the avoidance gap 125 can form a certain height difference between the contact in the avoidance hole 128 and the avoidance gap 125 and the printing contact 124, when the conductive medium is led to connect the contact in the avoidance hole 128 and the avoidance gap 125 with the printing contact 124, such as ink, the ink can become short circuit due to the existence of the height difference, so that the corresponding contact cannot be led to connect, and the risk of short circuit is further reduced.

Wherein at least two functional terminals 112 of the plurality of functional terminals 112 are electrically connected to each other. One of the at least two functional terminals 112 electrically connected to each other is for electrical connection with the graft storage element 122, and the other is for electrical connection with a printing apparatus adapted to a printing consumable.

In the embodiment disclosed by the application, the grafting chip 120 utilizes part of the circuit function of the original chip 110, so that the binding of the storage element is realized, and compared with the scheme in the related art, the application can realize the regeneration of elements with different pin contacts, so that the compatibility is better, and the regeneration difficulty of printing consumables or printing consumable chips is reduced.

In another alternative embodiment, the first substrate 111 may be provided with a first positioning portion 113. The second substrate 121 may be provided with a second positioning part 127. The first substrate 111 and the second substrate 121 may be positioned and engaged by the first positioning portion 113 and the second positioning portion 127. This scheme can further improve the assembly accuracy of the grafted chip 120 and the original chip 110.

Alternatively, the first positioning portion 113 on the first substrate 111 may be an existing positioning structure on the original chip 110, for example, a positioning structure on the original chip 110 that is in positioning engagement with the consumable body 200. In this case, the second positioning portion 127 may be provided only on the second substrate 121. Or the first positioning portion 113 on the first substrate 111 is a structure in which the original chip 110 is modified and then attached. One of the first positioning portion 113 and the second positioning portion 127 may be a positioning hole, and the other may be a positioning groove. Optionally, the main body of the printing consumable may have a bump structure, and after the alignment of the positioning hole and the positioning groove, the bump structure is melted, so as to fix the chip assembly. Of course, the first positioning portion 113 and the second positioning portion 127 may have other structures, which are not limited herein.

Based on the chip assembly 100 disclosed in the embodiment of the present application, the embodiment of the present application further discloses a printing consumable, where the disclosed printing consumable includes the chip assembly 100 described in any of the above embodiments.

The original chip 110 and the grafting chip 120 are attached to the consumable body 200. Specifically, since the original chip 110 is attached to the consumable body 200, the grafting chip 120 is covered on the original chip 110.

In the above embodiment, the graft storage element 122 on the graft chip 120 is disposed on the side surface of the second substrate 121 facing the consumable body 200. At this time, the consumable body 200 easily interferes with the graft storage element 122. Based on this, in another alternative embodiment, the consumable body 200 may be provided with a receiving groove 210, and at least a portion of the grafting storage element 122 may be located within the receiving groove 210. In this solution, at least a portion of the grafting storage element 122 may be located in the accommodating groove 210, so that the consumable body 200 is not easy to interfere with the grafting storage element 122, and the risk of damaging the grafting storage element 122 is avoided. In addition, the grafted storage element 122 is hidden in the accommodating groove 210, so that the stacking volume of the grafted chip 120 and the consumable body 200 can be reduced. In addition, the receiving groove 210 can also position the mounting position of the grafted memory element, thereby further improving the mounting accuracy of the grafted chip 120.

In the above embodiment, the graft storage element 122 may be located at the periphery of the functional terminal 112, that is, the graft storage element 122 is directly opposite to the consumable body 200, so that the original chip 110 does not need to be avoided.
