Description

Technical Field

[0001] The present invention relates to the field of printing imaging technology, and particularly to a chip component and a consumable cartridge component. Background Art

[0002] During the printing imaging process, the printing device needs the assistance of imaging auxiliary information of the consumable cartridge to complete the imaging process. The imaging auxiliary information of the printing device is recorded not only in the printing device but also on the consumable chip. The consumable chip can be installed on the consumable cartridge, and the consumable cartridge can be an ink cartridge filled with ink or a toner cartridge filled with toner. Ink cartridges and toner are recording materials. The function of the consumable chip is to control the authentication and data matching between the consumable cartridge and the printing device, and to provide imaging auxiliary information during the subsequent imaging process.

[0003] In the related art, a wafer and terminals for electrically connecting with the printing device's contact pins are provided on the consumable chip. Relevant information such as toner dosage information, manufacturer information, and serial number are stored in the wafer.

[0004] However, the terminals on the consumable chip are relatively dense, and the gaps between the terminals are small, which easily causes the contact pins of the printing device to contact the terminals with non-corresponding functions when the user installs or removes the consumable cartridge, resulting in a short circuit. Summary of the Invention

[0005] Embodiments of the present invention provide a chip component and a consumable cartridge component to solve the problem that the terminals on the consumable chip are relatively dense, and the gaps between the terminals are small, which easily causes the contact pins of the printing device to contact the terminals with non-corresponding functions when the user installs or removes the consumable cartridge, resulting in a short circuit.

[0010] The second chip includes a second substrate, the second substrate is provided with a second signal portion, the second signal portion is electrically connected to the second wafer, and the second signal portion is electrically connected to the first signal portion.

[0011] In a possible implementation manner, the first substrate includes a first substrate body and a first bending portion that are intersected and connected, and the first signal portion is disposed on the first bending portion;

[0012] The second substrate includes a second substrate body and a second bending portion that are intersected and connected, and the second signal portion is arranged on the second bending portion.

[0013] In a possible implementation manner, the chip assembly further includes an adapter component, the adapter component is provided with an adapter plate assembly, and the adapter plate assembly includes a contact pin contact surface and a chip contact surface;

[0014] The contact pin contact surface includes at least a third contact portion and a fourth contact portion; the third contact portion matches the first contact pin group, and the third contact portion is used to be electrically connected to the first contact pin group; the fourth contact portion matches the second contact pin group, and the fourth contact portion is used to be electrically connected to the second contact pin group;

[0015] The area of ​​the chip contact surface corresponding to the third contact portion is the first chip area, and the area of ​​the chip contact surface corresponding to the fourth contact portion is the second chip area. The first chip area and the second chip area are both correspondingly provided with chip contact portions, and the chip contact portions are used to contact the first chip or the second chip; the first chip area and the second chip area are both electrically connected to one of the same contact pin signal terminals in the first contact pin group and the second contact pin group.

[0016] In a possible implementation, the adapter board assembly further includes at least one first adapter board and at least one second adapter board. The first adapter board is formed with the first chip area, the second adapter board is formed with the second chip area, and at least some of the chip contact parts on the first adapter board are electrically connected to at least some of the chip contact parts on the second adapter board.

[0017] In a possible implementation, the first chip has a plurality of terminals. A plurality of protrusions are provided on one side of the first adapter board facing the first chip, and each protrusion is electrically connected to one terminal.

Consequently, the number of contact portions where the chip component contacts the contact pins of the printing device is decreased. Further, when installing or removing the consumable cartridge component, the contact between the contact pins of the printing device and the contact portions with non-corresponding functions can be reduced, avoiding short circuits and ensuring the normal use of the chip component.

Detailed implementation manners

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0047] In the present invention, unless otherwise clearly defined and limited, terms such as "installed", "connected", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher level than the second feature in terms of horizontal height. The first feature being "under", "beneath", and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower level than the second feature in terms of horizontal height.

[0049] In the above description, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0050] See Figure 1 , in the prior art, a communication port 10 is provided on a printing device 1, an interface module 20 is provided on a prior art chip 21', a communication link is established between the communication port 10 and the interface module 20, and the prior art consumable chip 21' on the prior art consumable cartridge 2 of the printing device 1 and Figure 5 can perform information transmission through the communication link. The prior art consumable cartridge 2 includes a prior art consumable chip 21', an upper surface 201 of the consumable cartridge, a front surface 202 of the consumable cartridge, and a side surface 203 of the consumable cartridge. The prior art consumable chip 21' is installed on the front surface 202 of the consumable cartridge, and the side surface 203 of the consumable cartridge intersects with the front surface 202 of the consumable cartridge. Figure 6 As shown, it is a set of consumable cartridges, specifically including 4 prior art consumable cartridges 2.

[0051] For example, during the imaging process, the prior art consumable chip 21' is used to provide identity recognition information and record the usage status information of the recording material (such as an ink cartridge or toner). When the printing device 1 sends a signal to the prior art consumable chip 21', the printing device 1 is the sender and the prior art consumable chip 21' is the receiver; when the prior art consumable chip 21' sends a signal to the printing device 1, the prior art consumable chip 21' is the sender and the printing device 1 is the receiver. The information transmission process between the printing device 1 and the prior art consumable chip 21' is achieved through the physical electrical contact between the contact pins on the printing device 1 and the terminals of the prior art consumable chip 21'.

[0052] Such as Figure 2 As shown, the printing device 1 includes a contact pin holder 11. The contact pin holder 11 includes an upper end surface 111 of the contact pin holder in the direction of the Y-axis arrow, a front end surface 112 of the contact pin holder in the direction of the X-axis arrow, and further includes a first contact pin 1101, a second contact pin 1102, a third contact pin 1103, a fourth contact pin 1104, and a fifth contact pin 1105 that are staggeredly distributed along the Z-axis direction, respectively corresponding to Figure 4correspond to the data terminal 2101, chip select terminal 2102, clock terminal 2103, power terminal 2104, and ground terminal 2105 on the consumable chip 21' of the prior art.

[0053] The printing device 1 sends a data signal to the consumable chip 21' of the prior art through the data terminal 2101, sends a chip select signal to the consumable chip 21' of the prior art through the chip select terminal 2102, sends a periodic clock signal with alternating low and high levels and repeated to the consumable chip 21' of the prior art through the clock terminal 2103, provides a working voltage for the consumable chip 21' of the prior art through the power terminal 2104, that is, the printing device 1 sends a power signal to the consumable chip 21' of the prior art through the power terminal 2104, and the printing device 1 provides a unified reference low level for receiving and sending data between the printing device 1 and the consumable chip 21' of the prior art through the ground terminal 2105, that is, the printing device 1 sends a ground signal to the consumable chip 21' of the prior art through the ground terminal 2105, ensuring the correctness and stability of the communication process.

[0054] As Figure 3 shown, the first contact pin 1101 includes a first contact pin top 11011, a first contact pin front end 11012, a first contact pin inclined end 11013, and a first contact pin tip 11014, all of which can be in contact with the terminals on the consumable chip for electrical connection. In this way, the consumable chip of the consumable cartridge can communicate with the printing device through the contact pins. In the prior art, the first contact pin 1101, the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104, and the fifth contact pin 1105 are respectively in contact with the data terminal 2101, chip select terminal 2102, clock terminal 2103, power terminal 2104, and ground terminal 2105 in the planar terminals of the consumable chip through the contact pin tips.

[0055] Each terminal is connected to the wafer on the consumable chip to achieve data transmission and storage. However, the terminals on the consumable chip are relatively dense, and the gap between the terminals is small, which is likely to cause the contact pins of the printing device to contact the terminals with non-corresponding functions when the user installs or removes the consumable cartridge, resulting in a short circuit.

[0056] To solve the above problems, the embodiments of the present invention provide a chip component and a consumable cartridge component. By reducing the number of contact parts corresponding to the contact pins of the printing device, when installing or removing the consumable cartridge component, the contact pins of the printing device can be reduced from contacting the contact parts with non-corresponding functions, avoiding short circuits and ensuring the normal use of the chip component.

[0057] The following will describe in detail the chip component and the consumable cartridge component provided by the embodiments of the present invention with reference to specific embodiments.

[0058] Example 1

[0059] Referring to Figure 7 as shown, an embodiment of the present invention provides a consumable cartridge assembly that can be installed in a printing device 1 (referring to Figure 1 ). The printing device 1 has at least one first probe group and at least one second probe group. Both the first probe group and the second probe group include a first probe 1101, a second probe 1102, a third probe 1103, a fourth probe 1104, and a fifth probe 1105.

[0060] In some examples, the first probe group and the second probe group have at least one same probe signal terminal. For example, both the first probe group and the second probe group have a fourth probe 1104 for transmitting a power signal, that is, the first probe group and the second probe group have the signal terminal of the same fourth probe 1104.

[0061] The consumable cartridge assembly includes a plurality of consumable cartridges. In some examples, the plurality of consumable cartridges includes at least one first consumable cartridge 21 and at least one second consumable cartridge 22.

[0062] The plurality of consumable cartridges are provided with a chip assembly. The chip assembly contacts the probes of the printing device 1 and receives printing signals.

[0063] Referring to Figure 8 as shown, the chip assembly includes at least one first chip 211.

[0064] The number of the first chips 211 is equal to the number of the first consumable cartridges 21. Each first chip 211 corresponds to a first consumable cartridge 21. The first consumable cartridge 21 includes the first chip 211, that is, the first chip 211 is disposed on the first consumable cartridge 21.

[0065] The number of the first chips 211 is equal to the number of the first probe groups. Each first chip 211 corresponds to a first probe group. The first chip 211 is matched with the first probe group, that is, when the consumable cartridge assembly can be installed in the printing device 1, the installation position of the first chip 211 is matched with the position of the first probe group.

[0066] The first chip 211 can perform information transmission with the printing device through the first probe group.

[0067] Referring to Figure 8 as shown, the first chip 211 is provided with a first wafer 2111. The first wafer 2111 is electrically connected to at least one first contact portion 2112. It can be understood that the first contact portion 2112 is electrically connected to the first wafer 2111, and data transmission and storage can be achieved. Exemplarily, the first contact portion 2112 can be electrically connected to the first wafer 2111 through a wire.

[0068] The first contact portion 2112 may be part of the first chip 211. In other embodiments, the first contact portion 2112 may also be part of the remaining components of the chip assembly after removing the first chip 211.

[0069] The first contact portion 2112 may be electrically connected to the first set of contact pins, so that the first chip 211 can perform a first electrical signal transmission with the printing device through the first contact portion 2112 and the first set of contact pins.

[0070] The first electrical signal may be one of a data signal, a chip select signal, a clock signal, a power signal, and a ground signal.

[0071] At least one second contact portion 2212 is electrically connected to the first wafer 2111. The second contact portion 2212 may be electrically connected to the second set of contact pins, so that the first chip 211 can perform a second electrical signal transmission with the printing device through the second contact portion 2212 and the second set of contact pins. With such an arrangement, the first chip 211 does not need to be provided with a contact portion having the same function as the second contact portion 2212 to contact the first set of contact pins, so that the number of contact portions of the first chip 211 in contact with the contact pins of the printing device is reduced, thereby reducing the number of contact portions of the chip assembly in contact with the contact pins of the printing device. Furthermore, when installing or removing the consumable cartridge assembly, the contact between the contact pins of the printing device and the contact portions with non-corresponding functions can be reduced, avoiding short circuits and ensuring the normal use of the chip assembly.

[0072] The second electrical signal may be one of a data signal, a chip select signal, a clock signal, a power signal, and a ground signal excluding the first electrical signal. For example, when the first electrical signal is a power signal, the second electrical signal may be a ground signal.

[0073] In a possible implementation manner, as shown in Figure 9 the chip assembly includes at least one second chip 221.

[0074] The number of the second chips 221 is equal to the number of the second consumable cartridges 22. Each second chip 221 corresponds to one second consumable cartridge 22. The second consumable cartridge 22 includes the second chip 221, that is, the second chip 221 is disposed on the second consumable cartridge 22.

[0075] The number of the second chips 221 is equal to the number of the second sets of contact pins. Each second chip 221 corresponds to one second set of contact pins. The second chip 221 is matched with the second set of contact pins, that is, when the consumable cartridge assembly can be installed on the printing device 1, the installation position of the second chip 221 is matched with the position of the second set of contact pins.

[0076] The second chip 221 can transmit information to the printing device through the second set of contact pins.

[0077] See Figure 9 As shown, the second chip 221 is provided with a second wafer 2211. The second wafer 2211 can be electrically connected to the first wafer 2111.

[0078] Both the first wafer 2111 and the second wafer 2211 are electrically connected to one of the same probe signal terminals in the first probe group and the second probe group. With such a setting, the first wafer 2111 and the second wafer 2211 can obtain the same electrical signal from one probe group of the printing device.

[0079] Exemplarily, both the first probe group and the second probe group have a fourth probe 1104 for transmitting a power signal, that is, the first probe group has a fourth probe 1104 for transmitting a power signal, and the second probe group has a fourth probe 1104 for transmitting a power signal. The first wafer 2111 and the second wafer 2211 can both be electrically connected to the fourth probe 1104 of the first probe group, so that the first wafer 2111 and the second wafer 2211 can obtain a power signal from the first probe group of the printing device 1.

[0080] Exemplarily, both the first probe group and the second probe group have a fifth probe 1105 for transmitting a ground signal, that is, the first probe group has a fifth probe 1105 for transmitting a ground signal, and the second probe group has a fifth probe 1105 for transmitting a ground signal. The first wafer 2111 and the second wafer 2211 can both be electrically connected to the fifth probe 1105 of the second probe group, so that the first wafer 2111 and the second wafer 2211 can obtain a ground signal from the second probe group of the printing device 1.

[0081] In a possible implementation manner, when the consumable cartridge assembly is installed in the printing device 1, the first contact portion 2112 can contact the first probe group. The second wafer 2211 of the second chip 221 is electrically connected to the first wafer 2111 of the first chip 211, which can enable the second chip 221 to obtain a first electrical signal from the first chip 211. As a result, the second chip 221 can be arranged not to provide a contact portion corresponding to the first electrical signal to contact the second probe group, which can reduce the number of contact portions of the second chip 221 with the probes of the printing device 1, and can reduce the number of contact portions of the chip assembly with the probes of the printing device 1. Furthermore, when installing or removing the consumable cartridge assembly, it is possible to reduce the contact between the probes of the printing device 1 and the contact portions that do not correspond to their functions, avoid short circuits, and ensure the normal use of the chip assembly.

[0082] In a possible implementation manner, see Figure 8 As shown, the first chip 211 includes a first substrate 2114. The first substrate 2114 is provided with a first signal portion 2113, and the first signal portion 2113 is electrically connected to the first wafer 2111. Exemplarily, the first signal portion 2113 can be electrically connected to the first wafer 2111 through a wire.

[0083] The second chip 221 includes a second substrate 2214, on which a second signal portion 2213 is provided. The second signal portion 2213 is electrically connected to the second wafer 2211 and is also electrically connected to the first signal portion 2113. With this arrangement, by electrically connecting the second signal portion 2213 to the first signal portion 2113, electrical connection between the first wafer 2111 of the first chip 211 and the second wafer 2211 of the second chip 221 can be achieved. When the consumable cartridge assembly is installed in the printing device 1, the second chip 221 can obtain a first electrical signal from the first chip 211.

[0084] Exemplarily, the first signal portion 2113 can be electrically connected to the first wafer 2111 through a wire. The second signal portion 2213 can be electrically connected to the second wafer 2211 through a wire.

[0085] It should be noted that in the related art, the consumable cartridge assembly can adopt an integrally formed chip assembly. Since the consumption of each consumable cartridge in the consumable cartridge assembly is different, after one consumable cartridge is used up and a new one needs to be replaced, the entire chip assembly needs to be replaced. However, the resources on the substrate corresponding to the consumable cartridge that has not been used up can obviously still be used, which will cause waste of resources and increase the material cost. Compared with the consumable cartridge assembly in the related art, the chip assembly of the consumable cartridge assembly in the present application is not integrally formed. After one consumable cartridge is used up and a new one needs to be replaced, the entire chip assembly does not need to be replaced, thereby avoiding waste of resources and increase in material cost.

[0086] In some examples, as shown in Figure 8 and Figure 9 the first substrate 2114 includes a first substrate main body and a first bending portion 211c that are intersectingly connected, and the first signal portion 2113 is provided on the first bending portion 211c. The second substrate 2214 includes a second substrate main body and a second bending portion 221c that are intersectingly connected, and the second signal portion 2213 is provided on the second bending portion 221c.

[0087] Among them, the first substrate main body of the first substrate 2114 is located on the front surface 202 of the consumable cartridge of the first consumable cartridge 21 (as shown in Figure 7 ), and the first bending portion 211c is located on the side surface 203 of the consumable cartridge of the first consumable cartridge 21 (as shown in Figure 7 ).

[0088] The second substrate main body of the second substrate 2214 is located on the front surface 202 of the consumable cartridge of the second consumable cartridge 22 (as shown in Figure 7 ), and the second bending portion 221c is located on the side surface 203 of the consumable cartridge of the second consumable cartridge 22 (as shown in Figure 7 ).

[0089] When the consumable cartridge assembly is installed in the printing device 1, the cartridge side surface 203 of the first consumable cartridge 21 contacts the cartridge side surface 203 of the second consumable cartridge 22, so that the second signal portion 2213 contacts the first signal portion 2113, realizing electrical connection between the second signal portion 2213 and the first signal portion 2113.

[0090] In some examples, the first substrate 2114 includes a connected first plate 211a and second plate 211b. The first wafer 2111 is disposed on the first plate 211a. The second plate 211b can electrically conduct the first wafer 2111 on the first plate 211a. The second plate 211b is partially bent toward the cartridge side surface 203 of the first consumable cartridge 21 to form a first bent portion 211c.

[0091] Exemplarily, the first plate 211a can be a rigid circuit board. The second plate 211b can be a flexible circuit board. The first plate 211a and the second plate 211b are welded together. The two ends of the second plate 211b can be bent toward the two cartridge side surfaces 203 of the first consumable cartridge 21 respectively to form two first bent portions 211c, and the first bent portion 211c is substantially perpendicular to the first plate 211a. The unbent portions of the first plate 211a and the second plate 211b can form a first substrate body. A first signal portion 2113 is disposed on each first bent portion 211c.

[0092] It should be noted that in other embodiments, in order to save the material of the second plate 211b, the first substrate 2114 can be provided with one first bent portion 211c.

[0093] In some examples, the second substrate 2214 includes a connected third plate 221a and fourth plate 221b. The second wafer 2211 is disposed on the third plate 221a. The fourth plate 221b can electrically conduct the second wafer 2211 on the third plate 221a. The fourth plate 221b is partially bent toward the cartridge side surface 203 of the second consumable cartridge 22 to form a second bent portion 221c.

[0094] Exemplarily, the third plate 221a can be a rigid circuit board. The fourth plate 221b can be a flexible circuit board. The third plate 221a and the fourth plate 221b are welded together. The two ends of the fourth plate 221b can be bent toward the two cartridge side surfaces 203 of the second consumable cartridge 22 respectively to form two second bent portions 221c, and the second bent portion 221c is substantially perpendicular to the third plate 221a. The unbent portions of the third plate 221a and the fourth plate 221b can form a second substrate body. A second signal portion 2213 is disposed on each second bent portion 221c.

[0095] In a possible implementation, a first wafer 2111 and at least one first contact portion 2112 are disposed on a first substrate body of the first chip 211.

[0096] A second wafer 2211 and at least one second contact portion 2212 are disposed on a second substrate body of the second chip 221. The second wafer 2211 is electrically connected to the second contact portion 2212, enabling data transmission and storage.

[0097] The second contact portion 2212 may be part of the second chip 221. In other embodiments, the second contact portion 2212 may also be part of the remaining components of the chip assembly excluding the second chip 221.

[0098] The second contact portion 2212 contacts the second set of contact pins. The second chip 221 can perform a second electrical signal transmission with the printing device through the second contact portion 2212 and the second set of contact pins, enabling the first chip 211 to obtain a second electrical signal from the second chip 221.

[0099] When the consumable cartridge assembly is installed in the printing device 1, the first chip 211 contacts the first set of contact pins through the first contact portion 2112, and the second chip 221 contacts the second set of contact pins through the second contact portion 2212. By electrically connecting the first wafer 2111 of the first chip 211 and the second wafer 2211 of the second chip 221, the second chip 221 can obtain a first electrical signal from the first chip 211, and the first chip 211 can obtain a second electrical signal from the second chip 221. As a result, there is no need to provide a contact portion corresponding to the second electrical signal on the first chip 211 to contact the first set of contact pins, and there is no need to provide a contact portion corresponding to the first electrical signal on the second chip 221 to contact the second set of contact pins. This can reduce the number of contact portions where the first chip 211 contacts the contact pins of the printing device 1, and can reduce the number of contact portions where the second chip 221 contacts the contact pins of the printing device 1. Consequently, the number of contact portions where the chip assembly contacts the contact pins of the printing device 1 can be reduced. Furthermore, when installing or removing the consumable cartridge assembly, the contact between the contact pins of the printing device 1 and the contact portions that do not correspond to their functions can be reduced, avoiding short circuits and ensuring the normal use of the chip assembly.

[0100] Exemplarily, the printing device 1 has one first set of contact pins and three second sets of contact pins. The consumable cartridge assembly includes one first consumable cartridge 21 and three second consumable cartridges 22. The chip assembly includes one first chip 211 and three second chips 221.

[0101] The first chip 211 includes data terminals 2101, chip select terminals 2102, clock terminals 2103, and power supply terminals. The portion of the power supply terminal that contacts the fourth contact pin 1104 is the first contact portion 2112. The first chip 211 does not have a ground terminal. The first electrical signal may be a power supply signal.

[0102] The second chip 221 includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, and a ground terminal. The portion of the ground terminal in contact with the fifth contact pin 1105 is the second contact portion 2212. The second chip 221 has no power terminal. The second electrical signal may be a ground signal.

[0103] When four consumable cartridges are installed in the printing device 1, the cartridge side surface 203 of the first consumable cartridge 21 contacts the cartridge side surface 203 of the second consumable cartridge 22, and the cartridge side surfaces 203 of the respective second consumable cartridges 22 contact each other, so that the first signal portion 2113 on the first chip 211 of the first consumable cartridge 21 is electrically connected to the second signal portion 2213 on the second chip 221 of the second consumable cartridge 22, and the second signal portions 2213 on the second chips 221 of two adjacent second consumable cartridges 22 are electrically connected.

[0104] The first chip 211 of the first consumable cartridge 21 can contact the second signal portion 2213 on the second chip 221 of the second consumable cartridge 22 through the first signal portion 2113, so that the first chip 211 of the first consumable cartridge 21 can obtain the ground signal of the second chip 221 of the second consumable cartridge 22.

[0105] One of the three second consumable cartridges 22, the second chip 221 thereof, can contact the first signal portion 2113 on the first chip 211 of the first consumable cartridge 21 through the second signal portion 2213, so that the second chips 221 of the three second consumable cartridges 22 can obtain the power signal of the first chip 211 of the first consumable cartridge 21.

[0106] It should be noted that the material of the first signal portion 2113 may be the same as the material of the terminals on the first chip 211. The material of the second signal portion 2213 may be the same as the material of the terminals on the second chip 221.

[0107] Embodiment 2

[0108] The difference between the consumable cartridge assembly in Embodiment 2 and the consumable cartridge assembly in Embodiment 1 is as follows: Refer to Figure 10 As shown, the first consumable cartridge 21 is an original consumable cartridge. The first chip 211 of the first consumable cartridge 21 includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, a power terminal 2104, and a ground terminal electrically connected to the first wafer 2111. The portion of the ground terminal in contact with the fifth contact pin 1105 is the first contact portion 2112.

[0109] The second chip 221 of the second consumable cartridge 22 includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, and a power terminal 2104 that are electrically connected to the second wafer 2211. The second consumable cartridge 22 does not have a ground terminal.

[0110] The first electrical signal may be a ground signal. The first chip 211 does not obtain the second electrical signal from the second chip 221.

[0111] When four consumable cartridges are installed in the printing device 1, the cartridge side surface of the first consumable cartridge 21 contacts the cartridge side surface of the second consumable cartridge 22, and the cartridge side surfaces of the respective second consumable cartridges 22 contact each other, so that the first signal portion 2113 on the first chip 211 of the first consumable cartridge 21 is electrically connected to the second signal portion 2213 on the second chip 221 of the second consumable cartridge 22, and the second signal portions 2213 on the second chips 221 of two adjacent second consumable cartridges 22 are electrically connected. The second chip 221 of one of the three second consumable cartridges 22 can contact the first signal portion 2113 on the first chip 211 of the first consumable cartridge 21 through the second signal portion 2213, so that the second chips 221 of the three second consumable cartridges 22 can obtain the ground signal of the first chip 211 of the first consumable cartridge 21.

[0112] The structures of the remaining parts are the same as those in the first embodiment and can bring the same or similar technical effects.

[0130] The stylus contact surface at least includes a third contact portion 2312 and a fourth contact portion 2412; the third contact portion 2312 is matched with the first stylus group, that is, when the consumable cartridge component can be installed on the printing device 1, the installation position of the third contact portion 2312 of the adapter component 3 is matched with the position of the first stylus group, and the third contact portion 2312 is used for electrical connection to the first stylus group; the fourth contact portion 2412 is matched with the second stylus group, that is, the installation position of the fourth contact portion 2412 of the adapter component 3 is matched with the position of the second stylus group, and the fourth contact portion 2412 is used for electrical connection to the second stylus group.

[0131] The area of the chip contact surface corresponding to the third contact portion 2312 is the first chip area, and the area of the chip contact surface corresponding to the fourth contact portion 2412 is the second chip area. Chip contact portions are provided corresponding to both the first chip area and the second chip area, and the chip contact portions are used to contact the first chip or the second chip.

[0132] There is at least one chip contact portion in both the first chip area and the second chip area, and this chip contact portion can be electrically connected to one of the same stylus signal terminals of the first stylus group and the second stylus group. With such a setting, it can be ensured that there is at least one chip contact portion in both the first chip area and the second chip area that obtains the same electrical signal from one stylus group of the printing device 1.

The sixth contact portion 2612 matches the fourth contact pin group, that is, when the consumable box assembly can be installed on the printing device 1, the installation position of the sixth contact portion 2612 of the adapter component 3 matches the position of the fourth contact pin group, and the sixth contact portion 2612 is used to electrically connect to the fourth contact pin group.

In this way, the first chip region, the second chip region, the third chip region, and the fourth chip region each have at least one chip contact portion to obtain the same electrical signal from a contact pin group of the printing device 1.

[0160] Exemplarily, the first contact pin group, the second contact pin group, the third contact pin group and the fourth contact pin group all have a fourth contact pin 1104 for sending a power signal. The first chip region, the second chip region, the third chip region and the fourth chip region all have a chip contact portion, which can be electrically connected to the fourth contact pin 1104 of the first contact pin group, so that the first chip region, the second chip region, the third chip region and the fourth chip region all have a chip contact portion that can obtain a power signal from the first contact pin group of the printing device 1.

[0161] In a possible implementation, the adapter board assembly further includes at least one third adapter board 313 and at least one fourth adapter board 314. The third adapter board 313 is formed with a third chip area. The fourth adapter board 314 is formed with a fourth chip area.

With such a setting, the first adapter board 311, the second adapter board 312, and the fourth adapter board 314 do not need to be provided with contact portions having the same function as the fifth contact portion 2512, and the first adapter board 311, the second adapter board 312, and the third adapter board 3134 do not need to be provided with contact portions having the same function as the sixth contact portion 2612. Thus, the number of contact portions where the chip assembly contacts the probes of the printing device can be reduced. Furthermore, when installing or removing the consumable cartridge assembly, the contact between the probes of the printing device and the contact portions with non-corresponding functions can be reduced, avoiding short circuits and ensuring the normal use of the chip assembly.

[0165] The third electrical signal can be a signal selected from data signals, chip select signals, clock signals, power supply signals, and ground signals, excluding the first electrical signal and the second electrical signal.

[0166] The fourth electrical signal can be a signal selected from data signals, chip select signals, clock signals, power supply signals, and ground signals, excluding the first electrical signal, the second electrical signal, the third electrical signal, and the fourth electrical signal.

The third protrusion 3153 of the first adapter board 311 is electrically connected to the clock terminal 2103 of the first chip 211. The fourth protrusion 3154 of the first adapter board 311 is electrically connected to the power terminal 2104 of the first chip 211. The fifth protrusion 3155 of the first adapter board 311 is electrically connected to the ground terminal 2105 of the first chip 211.

[0171] In a possible implementation manner, see Figure 13 As shown, looking down at the substrate of the first chip 211. All the contact parts on the substrate include the contact part between the data terminal 2101 and the first protrusion 3151, the contact part between the chip select terminal 2102 and the second protrusion 3152, the contact part between the clock terminal 2103 and the third protrusion 3153, the contact part between the power terminal 2104 and the fourth protrusion 3154, and the contact part between the ground terminal 2105 and the fifth protrusion 3155.

[0172] Exemplarily, the first contact part can be one of all the contact parts of the first chip 211. The second contact part can be one of all the contact parts of the second chip.

[0173] Set two orthogonal straight lines as the first imaginary line L1 and the second imaginary line L2, and project all the contact parts of the substrate onto the second imaginary line L2. The first imaginary line L1 passes through the middle of the two farthest projections among all the projections of the contact parts.

[0174] The first imaginary line L1 divides the substrate into two regions, namely the first region 21a1 and the second region 21a2.

[0175] In some examples, at least one contact portion is disposed on the first imaginary line L1. Exemplarily, the contact portion between the data terminal 2101 and the first protrusion 3151 can be disposed on the first imaginary line L1. With such an arrangement, since some contact portions are disposed in the middle of the substrate, the uniformity of the pressure exerted by the first adapter board 311 on the first chip 211 can be improved.

[0176] In some examples, the projections of at least two contact portions on the second imaginary line L2 may overlap. Compared with the prior art in which the contact portions are arranged in a staggered manner, the width of the substrate can be set smaller, which is more flexible in the process. Reducing the substrate width can reduce the installation difficulty of the substrate on the ink cartridge.

[0177] In some examples, the contact portions in the two regions are symmetrically arranged with respect to the first imaginary line L1. With such an arrangement, the uniformity of the pressure exerted by the first adapter board 311 on the first chip 211 can be improved, and poor contact caused by uneven force on the first chip 211 can be avoided.

[0178] Exemplarily, the first region 21a1 is provided with contact portions between the clock terminal 2103 and the third protrusion 3153 and between the power terminal 2104 and the fourth protrusion 3154. The second region 21a2 is provided with contact portions between the chip select terminal 2102 and the second protrusion 3152 and between the ground terminal 2105 and the fifth protrusion 3155. The contact portions in the first region 21a1 and the contact portions in the second region 21a2 are symmetrically arranged with respect to the first imaginary line L1.

[0179] In some examples, the number of contact portions in each region is less than or equal to three. Exemplarily, the number of contact portions in the first region 21a1 can be two. The number of contact portions in the second region 21a2 can be two. With such an arrangement, it is possible to avoid an excessive number of contact portions being disposed in the same region while having a large difference in the number of contact portions from another region, which may damage the uniformity of the pressure exerted by the first adapter board 311 on the first chip 211.

[0180] In some examples, the line connecting the centers of the clock terminal 2103, the ground terminal 2105, and the data terminal 2101 can form an equilateral triangle. With such an arrangement, the first chip 211 can ensure the spacing between the terminals within a limited area, which is beneficial to reducing the size of the chip, and at the same time avoid short circuits caused by ink or dust splashing onto the substrate.

[0181] It should be noted that the first chip 211, the second chip, the third chip, and the fourth chip are the same. The structures of the second chip, the third chip, and the fourth chip can refer to the first chip 211. The connection manner between the second chip and the second adapter board 312 is the same as the connection manner between the first chip 211 and the first adapter board 311.

It can be understood that the third adapter board 313 is also provided with a first protrusion 3151, a second protrusion 3152, a third protrusion 3153, a fourth protrusion 3154, and a fifth protrusion 3155.

It can be understood that the fourth adapter board 314 is also provided with a first protrusion 3151, a second protrusion 3152, a third protrusion 3153, a fourth protrusion 3154, and a fifth protrusion 3155.

[0182] In some examples, the third contact portion 2312 is disposed on a side of the first adapter board 311 away from the first chip 211, and the third contact portion 2312 can be electrically connected to the fourth protrusion 3154. The fourth contact portion 2412 is disposed on a side of the second adapter board 312 away from the second chip, and the fourth contact portion 2412 can be electrically connected to the fifth protrusion 3155. The fifth contact portion 2512 is disposed on a side of the third adapter board 313 away from the third chip, and the fifth contact portion 2512 can be electrically connected to the third protrusion 3153.
