Description

Technical Field

[0001] This invention relates to the field of printing imaging technology, and more particularly to a chip assembly and a consumable box assembly. Background Technology

[0002] During the printing process, the printing device requires imaging assistance information from the consumable cartridge to complete the imaging process. This imaging assistance information is recorded not only within the printing device itself but also on a consumable chip. The consumable chip can be installed on the consumable cartridge, which can be an ink cartridge filled with ink or a toner cartridge filled with toner. The ink cartridge and toner are the recording materials, and the consumable chip's function is to control the authentication and data matching between the consumable cartridge and the printing device, and to provide imaging assistance information during subsequent imaging processes.

[0003] In related technologies, the consumable chip is equipped with a wafer and terminals that are electrically connected to the stylus of the printing device. The wafer stores information such as toner dosage, manufacturer information, and serial number.

[0004] However, the terminals on the consumable chip are relatively dense and the gaps between the terminals are small, which can easily cause the printer's stylus to come into contact with terminals that do not correspond to its function when the user installs or removes the consumable cartridge, resulting in a short circuit. Summary of the Invention

[0005] This invention provides a chip assembly and a consumable cartridge assembly to solve the problem that the terminals on the consumable chip are relatively dense and the gaps between the terminals are small, which can easily cause short circuits when the user installs or removes the consumable cartridge, as the printing device's stylus may come into contact with terminals whose functions do not correspond to the chip's terminals.

[0006] On one hand, embodiments of the present invention provide a chip assembly for contacting and receiving printing signals with styluses of a printing device, the printing device having at least one first stylus group and at least one second stylus group, the first stylus group and the second stylus group having at least one identical stylus signal terminal, the chip assembly comprising:

[0007] At least one first chip is provided, the first chip being used to match the first probe group, the first chip being provided with a first wafer, the first wafer being electrically connected to at least one first contact portion, the first contact portion being used to be electrically connected to the first probe group; the first wafer being electrically connected to at least one second contact portion, the second contact portion being used to be electrically connected to the second probe group.

[0008] In one possible implementation, at least one second chip is further included, the second chip being configured to mate with the second pin group, the second chip being provided with a second wafer, the second wafer being electrically connected to the first wafer, and both the first wafer and the second wafer being electrically connected to one of the same pin signal terminals in the first pin group and the second pin group.

[0009] In one possible implementation, the first chip includes a first substrate, the first substrate being provided with a first signal section, the first signal section being electrically connected to the first wafer;

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

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

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

[0013] In one possible implementation, the chip assembly further includes an adapter component, the adapter component being provided with an adapter board assembly, the adapter board assembly including a pin contact surface and a chip contact surface;

[0014] The contact surface of the stylus includes at least a third contact portion and a fourth contact portion; the third contact portion is matched with the first stylus group and is used for electrical connection to the first stylus group; the fourth contact portion is matched with the second stylus group and is used for electrical connection to the second stylus 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. Both the first chip area and the second chip area are provided with chip contact portions, which are used to contact the first chip or the second chip. Both the first chip area and the second chip area are electrically connected to one of the same stylus signal terminals in the first stylus group and the second stylus group.

[0016] In one 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 having the first chip region, the second adapter board having the second chip region, and at least a portion of the chip contacts on the first adapter board being electrically connected to at least a portion of the chip contacts on the second adapter board.

[0017] In one possible implementation, the first chip has multiple terminals, and the first adapter plate has multiple protrusions on one side facing the first chip, each of the protrusions being electrically connected to one of the terminals. The first adapter plate is used to contact a portion of the contact pins of the first contact pin group.

[0018] In one possible implementation, the first contact portion is formed by one of the data terminal and the remaining terminal, and the second contact portion is formed by the remaining terminal after removing the above terminals.

[0019] In one possible implementation, the substrate of the first chip is viewed from above;

[0020] Two orthogonal straight lines are designated as the first imaginary line and the second imaginary line, and all contact portions on the substrate are projected onto the second imaginary line. The first imaginary line passes through the middle of the two farthest projections of all contact portions, and the first imaginary line divides the substrate into two regions.

[0021] The contact portion must satisfy at least one of the following conditions:

[0022] At least one of the contact portions is disposed on the first imaginary line;

[0023] The projections of at least two of the contact portions on the second imaginary line overlap;

[0024] The contact portions in the two regions are symmetrically arranged with respect to the first imaginary line;

[0025] The number of contact points in each of the regions is less than or equal to three.

[0026] On the other hand, embodiments of the present invention provide a consumable box assembly, including the chip assembly as described above.

[0027] This invention provides a chip assembly and a consumable cartridge assembly. A first wafer of the first chip is electrically connected to at least one first contact and at least one second contact. When the consumable cartridge assembly is installed in a printing device, the first contact is electrically connected to a first pin group, and the second contact is electrically connected to a second pin group. This eliminates the need for a contact on the first chip to have a function identical to the second contact to contact the first pin group, reducing the number of contacts between the first chip and the pins of the printing device. This further reduces the number of contacts between the chip assembly and the pins of the printing device, thus minimizing contact between the pins of the printing device and their non-functional contacts when installing or removing the consumable cartridge assembly, preventing short circuits, and ensuring the normal operation of the chip assembly.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

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

[0047] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

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

[0050] See Figure 1 In the prior art, the printing device 1 is provided with a communication port 10, and the prior art chip 21' is provided with an interface module 20. A communication link is established between the communication port 10 and the interface module 20, and the printing device 1 and Figure 5 The prior art consumable chip 21' on the prior art consumable box 2 can transmit information via a communication link. The prior art consumable box 2 includes the prior art consumable chip 21', a top surface 201, a front surface 202, and a side surface 203. The prior art consumable chip 21' is mounted on the front surface 202, and the side surface 203 intersects with the front surface 202. Figure 6 The image shows a complete set of consumable boxes, specifically including four existing consumable boxes 2.

[0051] For example, during the imaging process, the existing consumable chip 21' is used to provide identification information and record material (e.g., ink cartridge or toner) usage information. When the printing device 1 sends a signal to the existing consumable chip 21', the printing device 1 is the sender and the existing consumable chip 21' is the receiver; conversely, when the existing consumable chip 21' sends a signal to the printing device 1, the existing 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 existing consumable chip 21' is achieved through physical electrical contact between the contact portion of the stylus on the printing device 1 and the terminal of the existing consumable chip 21'.

[0052] like Figure 2 As shown, the printing device 1 includes a stylus holder 11, which includes an upper stylus holder surface 111 in the Y-axis arrow direction, a front stylus holder surface 112 in the X-axis arrow direction, and a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105 staggered along the Z-axis direction, respectively... Figure 4The data terminal 2101, chip select terminal 2102, clock terminal 2103, power terminal 2104 and ground terminal 2105 on the existing consumable chip 21' correspond to each other.

[0053] Printing device 1 sends data signals to the existing consumable chip 21' via data terminal 2101, sends chip select signals to the existing consumable chip 21' via chip select terminal 2102, sends periodic alternating low and high level clock signals to the existing consumable chip 21' via clock terminal 2103, provides operating voltage to the existing consumable chip 21' via power terminal 2104 (i.e., sends power signals to the existing consumable chip 21' via power terminal 2104), and provides a unified reference low level for receiving and transmitting data between printing device 1 and the existing consumable chip 21' via ground terminal 2105 (i.e., sends ground signals to the existing consumable chip 21' via ground terminal 2105), thus ensuring the correctness and stability of the communication process.

[0054] like Figure 3 As shown, the first contact pin 1101 includes a first contact pin tip 11011, a first contact pin front end 11012, a first contact pin bevel end 11013, and a first contact pin tip 11014, all of which can contact and electrically connect with the terminals on the consumable chip. In this way, the consumable chip in the consumable cartridge can communicate with the printing device via 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 all contact the data terminal 2101, the chip select terminal 2102, the clock terminal 2103, the power terminal 2104, and the ground terminal 2105 of the planar terminals of the consumable chip via their contact pin tips.

[0055] Each terminal is connected to the wafer on the consumable chip to enable data transmission and storage. However, the terminals on the consumable chip are relatively dense and the gaps between the terminals are small. This can easily cause the printer's stylus to come into contact with a terminal that does not correspond to its function when the user installs or removes the consumable cartridge, resulting in a short circuit.

[0056] To address the aforementioned issues, embodiments of the present invention provide a chip assembly and a consumable cartridge assembly. By reducing the number of contact portions corresponding to the stylus pins of the printing device, the contact between the stylus pins of the printing device and their non-corresponding contact portions can be reduced during the installation or removal of the consumable cartridge assembly, thus avoiding short circuits and ensuring the normal operation of the chip assembly.

[0057] The chip assembly and consumable box assembly provided in the embodiments of the present invention will be described in detail below with reference to specific embodiments.

[0058] Example 1

[0059] See Figure 7 As shown, an embodiment of the present invention provides a consumable cartridge assembly that can be installed on a printing device 1 (see [reference]). Figure 1 The printing device 1 has at least one first group of styluses and at least one second group of styluses. Both the first and second groups of styluses include a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105.

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

[0061] The consumable box assembly includes multiple consumable boxes. In some examples, the multiple consumable boxes include at least one first consumable box 21 and at least one second consumable box 22.

[0062] Multiple consumable cartridges are equipped with chip components. The chip components contact the stylus of the printing device 1 and receive printing signals.

[0063] See Figure 8 As shown, the chip assembly includes at least one first chip 211.

[0064] The number of first chips 211 is equal to the number of first consumable boxes 21. Each first chip 211 corresponds to one first consumable box 21. The first consumable box 21 includes the first chips 211, that is, the first chips 211 are disposed on the first consumable box 21.

[0065] The number of first chips 211 is equal to the number of first stylus groups. Each first chip 211 corresponds to one first stylus group. The first chip 211 and the first stylus group are matched, that is, when the consumable cartridge assembly can be installed into the printing device 1, the installation position of the first chip 211 matches the position of the first stylus group.

[0066] The first chip 211 can transmit information to the printing device through the first set of styluses.

[0067] See 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 to realize data transmission and storage. For example, the first contact portion 2112 can be electrically connected to the first wafer 2111 via 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 can be electrically connected to the first stylus group, so that the first chip 211 can transmit a first electrical signal to the printing device through the first contact portion 2112 and the first stylus group.

[0070] The first electrical signal can be one of the following: data signal, chip select signal, clock signal, power signal, or ground signal.

[0071] The first wafer 2111 is electrically connected to at least one second contact portion 2212. The second contact portion 2212 can be electrically connected to a second pin group, allowing the first chip 211 to transmit a second electrical signal to the printing device through the second contact portion 2212 and the second pin group. This configuration eliminates the need for the first chip 211 to have a contact portion with the same function as the second contact portion 2212 to contact the first pin group, reducing the number of contacts between the first chip 211 and the printing device pins. This reduces the number of contacts between the chip assembly and the printing device pins, thus minimizing contact between the printing device pins and their non-functional contacts during the installation or removal of the consumable cartridge assembly, preventing short circuits, and ensuring normal operation of the chip assembly.

[0072] The second electrical signal can be any signal other than the first electrical signal, such as a data signal, chip select signal, clock signal, power signal, or ground signal. For example, when the first electrical signal is a power signal, the second electrical signal can be a ground signal.

[0073] In one possible implementation, see Figure 9 As shown, the chip assembly includes at least one second chip 221.

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

[0075] The number of second chips 221 is equal to the number of second stylus groups. Each second chip 221 corresponds to one second stylus group. The second chips 221 are matched with the second stylus groups, that is, when the consumable cartridge assembly can be installed into the printing device 1, the installation position of the second chip 221 matches the position of the second stylus group.

[0076] The second chip 221 can transmit information to the printing device through the second stylus group.

[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 pin signal terminals in the first and second pin groups. This configuration allows the first wafer 2111 and the second wafer 2211 to receive the same electrical signal from one pin group of the printing device.

[0079] For example, both the first and second contact pin groups have a fourth contact pin 1104 for transmitting power signals; that is, both the first and second contact pin groups have a fourth contact pin 1104 for transmitting power signals. The first wafer 2111 and the second wafer 2211 can be electrically connected to the fourth contact pin 1104 of the first contact pin group, allowing the first wafer 2111 and the second wafer 2211 to obtain power signals from the first contact pin group of the printing device 1.

[0080] For example, both the first and second contact groups have a fifth contact 1105 that transmits a ground signal; that is, both the first and second contact groups have a fifth contact 1105 that transmits a ground signal. The first wafer 2111 and the second wafer 2211 can be electrically connected to the fifth contact 1105 of the second contact group, allowing the first wafer 2111 and the second wafer 2211 to obtain a ground signal from the second contact group of the printing device 1.

[0081] In one possible implementation, when the consumable cartridge assembly is installed in the printing device 1, the first contact portion 2112 can contact the first pin group. The second wafer 2211 of the second chip 221 is electrically connected to the first wafer 2111 of the first chip 211, allowing the second chip 221 to obtain a first electrical signal from the first chip 211. This eliminates the need for the second chip 221 to have a contact portion corresponding to the first electrical signal to contact the second pin group, reducing the number of contact portions between the second chip 221 and the pins of the printing device 1. This further reduces the number of contact portions between the chip assembly and the pins of the printing device 1, thereby minimizing contact between the pins of the printing device 1 and their non-corresponding contact portions during installation or removal of the consumable cartridge assembly, preventing short circuits, and ensuring normal operation of the chip assembly.

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

[0083] The second chip 221 includes a second substrate 2214, on which a second signal section 2213 is disposed. The second signal section 2213 is electrically connected to the second wafer 2211 and to the first signal section 2113. This configuration, through the electrical connection between the second signal section 2213 and the first signal section 2113, enables electrical connection between the first wafer 2111 of the first chip 211 and the second wafer 2211 of the second chip 221. 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] For example, the first signal unit 2113 can be electrically connected to the first wafer 2111 via a wire. The second signal unit 2213 can be electrically connected to the second wafer 2211 via a wire.

[0085] It should be noted that in related technologies, the consumable box assembly can use a one-piece molded chip assembly. Since the consumption of each consumable box varies, a new consumable box needs to be replaced after one is used up. This requires replacing the entire chip assembly, but the resources on the substrate corresponding to the unused consumable box are still usable, leading to resource waste and increased material costs. In contrast to the consumable box assemblies in related technologies, the chip assembly in this application is not one-piece molded. After one consumable box is used up, a new consumable box needs to be replaced without replacing the entire chip assembly, thus avoiding resource waste and increased material costs.

[0086] See in some examples Figure 8 and Figure 9 As shown, the first substrate 2114 includes a first substrate body and a first bent portion 211c that are intersected and connected, and a first signal portion 2113 is disposed on the first bent portion 211c. The second substrate 2214 includes a second substrate body and a second bent portion 221c that are intersected and connected, and a second signal portion 2213 is disposed on the second bent portion 221c.

[0087] The first substrate body of the first substrate 2114 is located on the front surface 202 of the first consumable box 21 (see...). Figure 7 As shown), the first bent portion 211c is located on the consumable box side surface 203 of the first consumable box 21 (see...). Figure 7 (As shown).

[0088] The second substrate body of the second substrate 2214 is located on the front surface 202 of the consumable box of the second consumable box 22 (see...). Figure 7 As shown), the second bent portion 221c is located on the consumable box side surface 203 of the second consumable box 22 (see...). Figure 7 (As shown).

[0089] When the consumable cartridge assembly is installed on the printing device 1, the consumable cartridge side surface 203 of the first consumable cartridge 21 and the consumable cartridge side surface 203 of the second consumable cartridge 22 come into contact with each other, so that the second signal unit 2213 comes into contact with the first signal unit 2113, thereby realizing the electrical connection between the second signal unit 2213 and the first signal unit 2113.

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

[0091] For example, the first board 211a can be a rigid circuit board. The second board 211b can be a flexible circuit board. The first board 211a and the second board 211b are soldered together. The two ends of the second board 211b can be bent toward the two consumable box side surfaces 203 of the first consumable box 21 to form two first bends 211c, which are approximately perpendicular to the first board 211a. The unbent portions of the first board 211a and the second board 211b can form the first substrate body. A first signal section 2113 is provided on each first bend 211c.

[0092] It should be noted that, in other embodiments, in order to save material on the second plate 211b, the first substrate 2114 may be provided with a first bending portion 211c.

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

[0094] For example, the third board 221a can be a rigid circuit board. The fourth board 221b can be a flexible circuit board. The third board 221a and the fourth board 221b are soldered together. The two ends of the fourth board 221b can be bent toward the two consumable box side surfaces 203 of the second consumable box 22 to form two second bends 221c, which are approximately perpendicular to the third board 221a. The unbent portions of the third board 221a and the fourth board 221b can form the second substrate body. A second signal section 2213 is provided on each second bend 221c.

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

[0096] The second substrate body of the second chip 221 is provided with a second wafer 2211 and at least one second contact portion 2212. The second wafer 2211 and the second contact portion 2212 are electrically connected, which can realize 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 after removing the second chip 221.

[0098] The second contact portion 2212 contacts the second stylus group, and the second chip 221 can transmit a second electrical signal to the printing device through the second contact portion 2212 and the second stylus group, so that the first chip 211 can obtain the 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 contact pin group through the first contact portion 2112, and the second chip 221 contacts the second contact pin group through the second contact portion 2212. The electrical connection between the first wafer 2111 of the first chip 211 and the second wafer 2211 of the second chip 221 allows the second chip 221 to obtain a first electrical signal from the first chip 211, and the first chip 211 to obtain a second electrical signal from the second chip 221. This eliminates the need for the first chip 211 to have a contact portion corresponding to the second electrical signal to contact the first contact pin group. The second chip 221 does not need to have a contact portion corresponding to the first electrical signal to contact the second pin group. This reduces the number of contact portions between the first chip 211 and the pins of the printing device 1, and also reduces the number of contact portions between the second chip 221 and the pins of the printing device 1. Consequently, the number of contact portions between the chip assembly and the pins of the printing device 1 is reduced. This minimizes the contact between the pins of the printing device 1 and their non-corresponding contact portions when installing or removing the consumable cartridge assembly, preventing short circuits and ensuring the normal operation of the chip assembly.

[0100] For example, the printing device 1 has a first group of styluses and three second groups of styluses. The consumable cartridge assembly includes a first consumable cartridge 21 and three second consumable cartridges 22. The chip assembly includes a first chip 211 and three second chips 221.

[0101] The first chip 211 includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, and a power terminal. The portion of the power terminal that contacts the fourth contact pin 1104 is the first contact portion 2112. The first chip 211 has no ground terminal. The first electrical signal can be a power 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 that contacts the fifth contact pin 1105 is the second contact portion 2212. The second chip 221 has no power supply terminal. The second electrical signal can be a ground signal.

[0103] When the four consumable boxes are installed in the printing device 1, the consumable box side surface 203 of the first consumable box 21 and the consumable box side surface 203 of the second consumable box 22 are in contact with each other, and the consumable box side surfaces 203 of each second consumable box 22 are in contact with each other, so that the first signal part 2113 on the first chip 211 of the first consumable box 21 is electrically connected to the second signal part 2213 on the second chip 221 of the second consumable box 22, and the second signal parts 2213 on the second chip 221 of two adjacent second consumable boxes 22 are electrically connected.

[0104] The first chip 211 of the first consumable box 21 can contact the second signal section 2213 on the first signal section 2113 and the second chip 221 of the second consumable box 22, so that the first chip 211 of the first consumable box 21 can obtain the grounding signal of the second chip 221 of the second consumable box 22.

[0105] The second chip 221 of one of the three second consumable boxes 22 can contact the first signal section 2113 on the first chip 211 of the first consumable box 21 through the second signal section 2213, so that the second chips 221 of the three second consumable boxes 22 can obtain the power signal of the first chip 211 of the first consumable box 21.

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

[0107] Example 2

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

[0109] The second chip 221 of the second consumable box 22 includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, and a power terminal 2104 electrically connected to the second wafer 2211. The second consumable box 22 has no ground terminal.

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

[0111] When the four consumable cartridges are installed in the printing device 1, the consumable cartridge side surface of the first consumable cartridge 21 and the consumable cartridge side surface of the second consumable cartridge 22 are in contact with each other. This contact allows the first signal section 2113 on the first chip 211 of the first consumable cartridge 21 to be electrically connected to the second signal section 2213 on the second chip 221 of the second consumable cartridge 22. The second signal sections 2213 on the second chips 221 of adjacent second consumable cartridges 22 are also electrically connected. The second chip 221 of one of the three second consumable cartridges 22 can contact the first signal section 2113 on the first chip 211 of the first consumable cartridge 21 through the second signal section 2213, allowing all three second chips 221 to receive the ground signal from the first chip 211 of the first consumable cartridge 21.

[0112] The structure of the remaining parts is the same as that of Embodiment 1, and can bring the same or similar technical effects.

[0113] Example 3

[0114] This invention provides a consumable cartridge assembly that can be installed in a printing device 1 (see...). Figure 1 (As shown). The printing device 1 has at least one first group of styluses and at least one second group of styluses. Both the first and second groups of styluses include a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105.

[0115] In some examples, the first and second contact pin groups have at least one identical contact pin signal terminal. For example, both the first and second contact pin groups have a fourth contact pin 1104 for transmitting power signals.

[0116] The consumable cartridge assembly includes multiple consumable cartridges. In some examples, the multiple consumable cartridges include at least one first consumable cartridge 21 (see [link to example]). Figure 11 and Figure 12 (as shown) and at least one second consumable box.

[0117] Multiple consumable cartridges are equipped with chip components. The chip components contact the stylus of the printing device 1 and receive printing signals.

[0118] The chip assembly includes at least one first chip 211 and at least one second chip.

[0119] The number of first chips 211 is equal to the number of first consumable boxes 21. Each first chip 211 corresponds to one first consumable box 21. The first consumable box 21 includes the first chips 211, that is, the first chips 211 are disposed on the first consumable box 21.

[0120] The number of first chips 211 is equal to the number of first stylus groups. Each first chip 211 corresponds to one first stylus group. The matching of the first chip 211 with the first stylus group means that the first chip 211 can transmit information with the printing device through the first stylus group.

[0121] 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. It is understood that the first contact portion is electrically connected to the first wafer 2111 to realize data transmission and storage.

[0122] The first contact portion can be electrically connected to the first stylus group, so that the first chip 211 can transmit a first electrical signal to the printing device through the first contact portion 2112 and the first stylus group.

[0123] The first electrical signal can be one of the following: data signal, chip select signal, clock signal, power signal, or ground signal.

[0124] The first wafer 2111 is electrically connected to at least one second contact portion. The second contact portion can be electrically connected to a second pin group, so that the first chip 211 can transmit a second electrical signal to the printing device through the second contact portion and the second pin group.

[0125] The second electrical signal can be any signal other than the first electrical signal, such as a data signal, chip select signal, clock signal, power signal, or ground signal.

[0126] The number of second chips is equal to the number of second consumable boxes. Each second chip corresponds to one second consumable box. The second consumable box includes the second chip; that is, the second chip is disposed on the second consumable box.

[0127] The number of second chips is equal to the number of second pin groups. Each second chip corresponds to one second pin group. The matching of second chips and second pin groups means that the second chip can transmit information to the printing device through the second pin groups.

[0128] In some examples, the second chip is provided with a second wafer. The second wafer can be electrically connected to the first wafer 2111 so that the second chip obtains a first electrical signal from the first chip 211.

[0129] In one possible implementation, see Figure 11 and Figure 14 As shown, the chip assembly also includes an adapter component 3, which includes a stylus contact surface and a chip contact surface. The surface of the adapter component 3 that contacts the stylus of the printing device 1 is the stylus contact surface. The surface of the adapter board assembly that contacts the chip of the consumable cartridge assembly is the chip contact surface.

[0130] The contact surface of the stylus includes at least 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 assembly can be installed to the printing device 1, the installation position of the third contact portion 2312 of the adapter 3 matches the position of the first stylus group, and the third contact portion 2312 is used to electrically connect 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 3 matches the position of the second stylus group, and the fourth contact portion 2412 is used to electrically connect 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. Both the first chip area and the second chip area are provided with chip contact portions, which are used to contact the first chip or the second chip.

[0132] Both the first chip region and the second chip region have at least one chip contact portion, which can be electrically connected to one of the same pin signal terminals in the first and second pin groups. This arrangement allows each of the first and second chip regions to receive the same electrical signal from a pin group of the printing device 1.

[0133] For example, both the first and second contact pin groups have a fourth contact pin 1104 for transmitting power signals; that is, both the first and second contact pin groups have a fourth contact pin 1104 for transmitting power signals. Both the first and second chip regions have a chip contact portion that can be electrically connected to the fourth contact pin 1104 of the first contact pin group, so that both the first and second chip regions have a chip contact portion that can obtain power signals from the first contact pin group of the printing device 1.

[0134] In one possible implementation, the adapter 3 is provided with an adapter board assembly, which includes at least one first adapter board 311, the first adapter board 311 having a first chip region.

[0135] The adapter board assembly also includes at least one second adapter board 312. The second adapter board 312 has a second chip region formed thereon.

[0136] At least a portion of the chip contacts on the first adapter board 311 are electrically connected to at least a portion of the chip contacts on the second adapter board 312.

[0137] In some examples, a first adapter board 311 is electrically connected between the first chip 211 and the first contact pin group.

[0138] A second adapter board 312 is electrically connected between the second chip and the second contact pin group.

[0139] See Figure 14 As shown, the first adapter plate 311 has at least one third contact portion 2312 on the side facing the first stylus group, allowing the first adapter plate 311 to transmit a first electrical signal to the printing device through the third contact portion 2312 and the first stylus group, so that the second adapter plate 312 can obtain the first electrical signal from the first adapter plate 311. The second adapter plate 312 has at least one fourth contact portion 2412 on the side facing the second stylus group, allowing the second adapter plate 312 to transmit a second electrical signal to the printing device through the fourth contact portion 2412 and the second stylus group, so that the first adapter plate 311 can obtain the second electrical signal from the second adapter plate 312. This configuration allows the first adapter plate 311 to avoid having a contact portion with the same function as the fourth contact portion 2412 to contact the first pin group, and the second adapter plate 312 to avoid having a contact portion with the same function as the third contact portion 2312 to contact the second pin group. This reduces the number of contact portions between the chip assembly and the printing device's pins, thereby reducing the contact between the printing device's pins and their non-corresponding contact portions when installing or removing the consumable cartridge assembly, preventing short circuits, and ensuring the normal operation of the chip assembly.

[0140] In one possible implementation, the first consumable box 21 and the second consumable box can be installed on the adapter 3.

[0141] The adapter 3 includes an insert portion 34, at least one snap-fit ​​portion 33, and a cutout portion 32.

[0142] The adapter board assembly can be embedded in the embedded part 34.

[0143] The number of first chips 211 is equal to the number of first adapter boards 311. The number of second chips is equal to the number of second adapter boards 312.

[0144] Both the first consumable box 21 and the second consumable box include an ink outlet 23. The ink outlet 23 of the first consumable box 21 and the ink outlet of the second consumable box are in contact with the ink intake port 13 of the print head 12 through the cutout portion 32, so that the ink can flow.

[0145] The snap-fit ​​part 33 can snap onto the printhead 12, so that the adapter part 3 can be installed in the printhead 12.

[0146] When the first consumable box 21 and the second consumable box are installed on the adapter 3, the first chip 211 on the first consumable box 21 and the second chip on the second consumable box are embedded in the embedding part 34. The first chip 211 is electrically connected to the first chip area of ​​the first adapter board 311, and the second chip is electrically connected to the second chip area of ​​the second adapter board.

[0147] When the consumable cartridge assembly is installed in the printing device 1, the adapter 3 of the consumable cartridge assembly is installed in the print carriage 12. The first adapter plate 311 contacts the first stylus group through the third contact part 2312, and the second adapter plate 312 contacts the second stylus group through the fourth contact part 2412.

[0148] In one possible implementation, the printing device 1 has at least one third group of styluses and at least one fourth group of styluses. Both the third and fourth groups of styluses include a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105.

[0149] In some examples, the first, second, third, and fourth contact pin groups have at least one identical contact pin signal terminal. For example, the first, second, third, and fourth contact pin groups all have a fourth contact pin 1104 that transmits a power signal; that is, the first, second, third, and fourth contact pin groups have the same signal terminal for the fourth contact pin 1104.

[0150] In some examples, the consumable box assembly includes at least one third consumable box and at least one fourth consumable box.

[0151] The chip assembly also includes at least one third chip and at least one fourth chip.

[0152] The number of third chips is equal to the number of third consumable boxes. The number of fourth chips is equal to the number of fourth consumable boxes.

[0153] Each third chip corresponds to a third consumable box. The third consumable box contains the third chip; that is, the third chip is located on the third consumable box. Each fourth chip corresponds to a fourth consumable box. The fourth consumable box contains the fourth chip; that is, the fourth chip is located on the fourth consumable box.

[0154] The number of third chips is equal to the number of third contact pin groups, with each third chip corresponding to one third contact pin group. The number of fourth chips is equal to the number of fourth contact pin groups, with each fourth chip corresponding to one fourth contact pin group.

[0155] The third chip is matched with the third pin group; that is, when the consumable cartridge assembly can be installed into the printing device 1, the installation position of the third chip matches the position of the third pin group. The fourth chip is matched with the fourth pin group; that is, when the consumable cartridge assembly can be installed into the printing device 1, the installation position of the fourth chip matches the position of the fourth pin group.

[0156] The third chip has a third wafer. The fourth chip has a fourth wafer.

[0157] In some examples, the contact surface of the adapter component 3 includes at least a fifth contact portion 2512 and a sixth contact portion 2612. The fifth contact portion 2512 mates with the third contact group; that is, when the consumable cartridge assembly can be installed to the printing device 1, the mounting position of the fifth contact portion 2512 of the adapter component 3 matches the position of the third contact group, and the fifth contact portion 2512 is used for electrical connection to the third contact group. The sixth contact portion 2612 mates with the fourth contact group; that is, when the consumable cartridge assembly can be installed to the printing device 1, the mounting position of the sixth contact portion 2612 of the adapter component 3 matches the position of the fourth contact group, and the sixth contact portion 2612 is used for electrical connection to the fourth contact group.

[0158] The area of ​​the chip contact surface corresponding to the fifth contact portion 2512 is the third chip area. A chip contact portion that contacts the third chip is provided in the third chip area. The area of ​​the chip contact surface corresponding to the sixth contact portion 2612 is the fourth chip area. A chip contact portion that contacts the fourth chip is provided in the fourth chip area.

[0159] Each of the first, second, third, and fourth chip regions has at least one chip contact portion, which is electrically connected to one of the same pin signal terminals in the first, second, third, and fourth pin groups. This arrangement ensures that each of the first, second, third, and fourth chip regions has at least one chip contact portion that receives the same electrical signal from a pin group of the printing device 1.

[0160] For example, the first, second, third, and fourth contact pin groups each have a fourth contact pin 1104 for transmitting power signals. Each of the first, second, third, and fourth chip regions has a chip contact portion that can be electrically connected to the fourth contact pin 1104 of the first contact pin group, enabling each of these chip regions to obtain a power signal from the first contact pin group of the printing device 1.

[0161] In one 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 has a third chip region. The fourth adapter board 314 has a fourth chip region.

[0162] A third adapter board 313 is electrically connected between the third chip and the third contact pin group. The number of third adapter boards 313 is equal to the number of third chips.

[0163] A fourth adapter board 314 is electrically connected between the fourth chip and the fourth contact pin group. The number of fourth adapter boards 314 is equal to the number of fourth chips.

[0164] The third adapter plate 313 has at least one fifth contact portion 2512 on the side facing the third contact pin group, so that the first adapter plate 311, the second adapter plate 312, and the fourth adapter plate 314 can obtain a third electrical signal from the third adapter plate 313. The fourth adapter plate 314 has at least one sixth contact portion 2612 on the side facing the fourth contact pin group, so that the first adapter plate 311, the second adapter plate 312, and the third adapter plate 313 can obtain a fourth electrical signal from the fourth adapter plate 314. This configuration allows the first adapter board 311, the second adapter board 312, and the fourth adapter board 314 to be free from having contact parts with the same function as the fifth contact part 2512, and the first adapter board 311, the second adapter board 312, and the third adapter board 3134 to be free from having contact parts with the same function as the sixth contact part 2612. This reduces the number of contact parts between the chip assembly and the printing device's stylus, thereby reducing the contact between the printing device's stylus and its non-corresponding contact parts when installing or removing the consumable cartridge assembly, preventing short circuits, and ensuring the normal operation of the chip assembly.

[0165] The third electrical signal can be any signal obtained by removing the first and second electrical signals from the data signal, chip select signal, clock signal, power signal, and ground signal.

[0166] The fourth electrical signal can be any signal obtained by removing the first, second, third, and fourth electrical signals from the data signal, chip select signal, clock signal, power signal, and ground signal.

[0167] In one possible implementation, the first chip 211 has multiple terminals, and the first adapter plate 311 is provided with multiple protrusions on the side facing the first chip 211, each protrusion being electrically connected to a terminal. The first adapter plate 311 is used to contact a portion of the contact pins of the first contact pin group.

[0168] For example, see Figure 13As shown, the first chip 211 is provided with a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, a power terminal 2104, and a ground terminal 2105. The data terminal 2101, chip select terminal 2102, clock terminal 2103, power terminal 2104, and ground terminal 2105 of the first chip 211 are all electrically connected to the first wafer 2111.

[0169] See Figure 14 As shown, the first adapter board 311 has a first protrusion 3151, a second protrusion 3152, a third protrusion 3153, a fourth protrusion 3154, and a fifth protrusion 3155 on the side near the first chip 211. The first protrusion 3151, the second protrusion 3152, the third protrusion 3153, the fourth protrusion 3154, and the fifth protrusion 3155 can be made of metal.

[0170] The first protrusion 3151 of the first adapter board 311 is electrically connected to the data terminal 2101 of the first chip 211. The second protrusion 3152 of the first adapter board 311 is electrically connected to the chip select terminal 2102 of the first chip 211. 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 one possible implementation, see Figure 13 As shown, the substrate of the first chip 211 is viewed from above. All the contacts on the substrate include the contact between the data terminal 2101 and the first protrusion 3151, the contact between the chip select terminal 2102 and the second protrusion 3152, the contact between the clock terminal 2103 and the third protrusion 3153, the contact between the power terminal 2104 and the fourth protrusion 3154, and the contact between the ground terminal 2105 and the fifth protrusion 3155.

[0172] For example, the first contact portion can be one of all the contact portions of the first chip 211. The second contact portion can be one of all the contact portions of the second chip.

[0173] Two orthogonal straight lines are designated as the first imaginary line L1 and the second imaginary line L2. All the contact portions of the substrate are projected onto the second imaginary line L2. The first imaginary line L1 passes through the middle of the two farthest projections of all the contact portions.

[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. For example, the contact portion between the data terminal 2101 and the first protrusion 3151 may be disposed on the first imaginary line L1. This arrangement, with a portion of the contact portion disposed in the middle of the substrate, can improve the uniformity of the pressure applied by the first adapter plate 311 to the first chip 211.

[0176] In some examples, at least two contacts can overlap in projection on the second imaginary line L2. Compared to the prior art where the contacts are staggered, this implementation allows for a smaller substrate width, greater manufacturing flexibility, and reduced substrate width, thus simplifying the mounting process 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. This arrangement can improve the uniformity of the pressure applied by the first adapter plate 311 to the first chip 211, and avoid poor contact of the first chip 211 due to uneven force.

[0178] For example, the first region 21a1 is provided with a contact portion between the clock terminal 2103 and the third protrusion 3153, and a contact portion between the power terminal 2104 and the fourth protrusion 3154. The second region 21a2 is provided with a contact portion between the chip select terminal 2102 and the second protrusion 3152, and a contact portion 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 contacts in each region is less than or equal to three. For example, the number of contacts in the first region 21a1 can be two. The number of contacts in the second region 21a2 can also be two.
