Description

TECHNICAL FIELD

[0001] The utility model relates to the field of printing equipment, especially a consumable chip and a consumable box. BACKGROUND

[0002] In current printing technology, the consumable box serves as a bridge connecting the printing device and the consumable, playing a crucial role. However, with the continuous development of technology, the connection problem between the consumable box and the printing device stylus gradually highlights, bringing challenges to the stable operation of the device and the user experience.

[0003] Firstly, the terminals on the consumable chip are increasingly dense, aiming to improve data transmission efficiency and space utilization. However, this design also poses potential risks. During the user's installation or removal of the consumable box, due to careless operation or device precision limitations, the stylus can easily touch the terminals that do not correspond to the function, causing a short circuit. Short circuit not only causes data transmission errors, but also can damage the printing device, increasing maintenance costs.

[0004] Secondly, during the long-term use of the consumable chip, it may shift due to factors such as device vibration, temperature change, or material aging. When the chip shifts, the printer stylus cannot accurately hold the chip, causing unstable connection. This not only affects the normal transmission of data, but also can cause device failure, reducing printing efficiency.

DETAILED DESCRIPTION

[0057] The utility model will be described in further detail below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the utility model.

Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0059] In the utility model, unless otherwise specifically defined and limited, the terms "mounting", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected or in communication with each other; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited.

In this specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine different embodiments or examples described in the specification and the features of different embodiments or examples without contradiction.

[0062] As shown in Figures 1 to 5 A consumable box 2, which is a component frequently replaced on a printing device 1, can be detachably installed on the printing device 1, and can be an ink cartridge, a toner cartridge, a ribbon, etc., and stores developing medium such as ink or toner therein, and can be used to provide developing medium for the printing device 1, and the printing device 1 prints by providing consumables (such as ink or toner) through the consumable box 2.

[0063] The printing device 1 is provided with a communication port 10, and the consumable box 2 is provided with a consumable chip 21', as shown in Figure 1 The consumable 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 the consumable chip 21' on the consumable box 2 can transmit information through the communication link. For example, in the imaging process, the consumable chip 21' is used to provide identity information and record material usage information. When the printing device 1 sends a signal to the consumable chip 21', the printing device 1 is the sender and the consumable chip 21' is the receiver; while the consumable chip 21' sends a signal to the printing device 1, the consumable chip 21' is the sender and the printing device 1 is the receiver.

[0064] The information transmission process between the printing device 1 and the consumable chip 21' is realized by physical electrical contact between the stylus on the printing device 1 and the contact part on the consumable chip 21' of the prior art.

[0065] In the specification, in order to better describe the corresponding structure, the length direction of the consumable box 2 in the drawing is defined as the X-axis direction, the width direction of the consumable box 2 is defined as the Z-axis direction, and the height direction of the consumable box 2 (also the negative direction of the installation direction) is defined as the Y-axis direction.

[0066] As shown in Figure 5 The consumable box 2 includes a consumable box upper surface 201 located above the Y-axis direction and a consumable box front surface 202 located on the -X side of the X-axis direction, and the consumable chip 21' is installed on the consumable box front surface 202.

[0067] The print device 1 includes a stylus rack 11, and when the consumable box 2 is installed on the print device, the direction of the print device 1 is consistent with the direction of the consumable box 2, the stylus rack 11 includes a stylus rack upper end surface 111 facing the Y-axis and a stylus rack front end surface 112 facing the X-axis, and the stylus rack upper end surface 111 intersects with the stylus rack front end surface 112. When the consumable box 2 is installed on the print device 1, the stylus rack front end surface 112 is arranged opposite to the consumable box front surface 202, that is, the stylus rack front end surface 112 faces the consumable box 2.

[0068] The print device 1 further includes a plurality of styluses arranged on the stylus rack 11, and the plurality of styluses are specifically a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105. When the consumable box 2 is installed on the print device 1, the above-mentioned styluses can respectively contact the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 arranged on the consumable chip 21'.

[0069] Preferably, the terminals can be respectively a data contact SDA, a chip selection contact RST, a clock contact SCL, a power supply contact VCC, and a ground contact GND. The print device 1 sends a data signal to the consumable chip 21' through the data contact SDA, the print device 1 sends a chip selection signal to the prior art consumable chip 21' through the chip selection contact RST, the print device 1 sends a clock signal with periodic low level and high level alternation and repetition to the prior art consumable chip 21' through the clock contact SCL, the print device 1 provides a working voltage for the prior art consumable chip 21' through the power supply contact VCC, and the print device 1 provides a unified reference low level for receiving and transmitting data between the print device 1 and the prior art consumable chip 21' through the ground contact GND, which ensures the correctness and stability of the communication process.

[0070] As shown in Figure 2 , Figure 3As shown, the first contact 1101, the second contact 1102, the third contact 1103, the fourth contact 1104, and the fifth contact 1105 among the multiple contact pins all have the same structure. Now, taking the first contact 1101 as an example, the first contact 1101 includes a first contact tip 11011, a first contact front end 11012, a first contact bevel end 11013, and a first contact tip 11014. The first contact tip 11011, the first contact front end 11012, the first contact bevel end 11013, and the first contact tip 11014 can all make contact with the terminals on the consumable chip and be electrically connected. In this way, the consumable chip 21' of the consumable cartridge 2 can communicate with the printing device 1 through the contact pins.

[0071] When the consumable cartridge 2 is installed in the printing device 1, 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 make contact with the data contact SDA, the chip select contact RST, the clock contact SCL, the power contact VCC, and the ground contact GND in the planar terminals of the consumable chip through the contact pin tips. The contact pins are telescopic and can extend or retract a certain distance when contacting the consumable chip.

[0072] However, because the terminals on the consumable chip 21' in the prior art (as described above) are arranged in two rows, which are relatively dense and the gaps between the terminals are very small, it is easy for the contact pins of the printing device 1 to make contact with terminals that do not correspond to their functions when the user installs the consumable box 2 on the printing device 1, resulting in a short circuit; in addition, the consumable chip is prone to downward displacement during this process and cannot form an effective electrical connection with the printing device 1.

[0073] Therefore, this application provides a solution for redesigning the terminals of a consumable chip.

[0074] Example 1

[0075] like Figures 6 to 8 As shown, in this embodiment, the consumable chip 21 has terminals divided into two parts, each set at a different position, separating the terminals. This solves the problem of short circuits caused by the contact between the stylus of the printing device 1 and the terminal that does not correspond to its function, which prevents the printing device 1 and the consumable chip 21 from receiving and sending data, thus failing to guarantee the correctness and stability of the communication process. Moreover, this terminal distribution method allows the stylus to clamp the consumable chip 21 when it contacts the terminal, preventing the consumable chip 21 from easily shifting and failing to form an effective electrical connection with the printing device 1.

[0076] like Figures 6 to 7 As shown, a consumable chip 21 includes a substrate 210, a terminal group disposed on the substrate 210, and a circuit module 21021.

[0077] The substrate 210 has a first plane 2101 and a second plane 2102 oppositely arranged, and a plurality of terminals are arranged on the substrate 210. Among them, part of the terminals are arranged on the first plane 2101, and another part of the terminals are arranged on the second plane 2102.

[0078] Preferably, when the consumable chip 21 is mounted on the consumable cartridge 2, the first plane 2101 is the plane facing the stylus, the second plane 2102 is the plane connected to the consumable cartridge 2, and the width direction of the consumable chip 21 is the Z-axis direction.

[0079] Specifically, in the embodiment, the terminal group also includes first to fifth terminals 21011-21015. Among them, the first terminal 21011, the second terminal 21012, the fourth terminal 21014 and the fifth terminal 21015 are arranged on the first plane 2101 of the substrate 210, and the third terminal 21013 and the circuit module 21021 are arranged on the second plane 2102, so that the terminals of the consumable chip 21 are separated.

[0080] The circuit module 21021 includes a storage module storing information such as the production information of the consumable cartridge 2, the consumable amount information, the category information of the consumable cartridge 2, and the color information. The first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 are all electrically connected to the circuit module 21021 through wires, so as to facilitate the consumable chip 21 to complete corresponding work and realize corresponding functions. When the terminals are connected with the stylus, the printing device 1 can read the information of the consumable cartridge 2 stored in the circuit module 21021.

[0081] It should be noted that the circuit module 21021 can be theoretically arranged on any one plane of the substrate 210, but since the arrangement area of the substrate 210 is limited, it is preferred to arrange the circuit module 21021 on the second plane 2102 or the inside of the substrate 210.

[0082] Part of the terminals are also arranged on the edge of the second plane 2102 (i.e. the side of the substrate 210 in the Z-axis direction). Preferably, when the third terminal 21013 is arranged on the second plane 2102, the third terminal 21013 is at least partially located on the edge of the second plane 2102 (i.e. the third terminal 21013 is at least partially located on the side of the substrate 210 in the Z-axis direction).

[0083] Specifically, in this embodiment, the third terminal 21013 has a part protruding from the substrate 210, i.e., a protruding part 210131, wherein when the third terminal 21013 is mounted on the second plane 2102, the protruding part 210131 on the third terminal 21013 does not overlap the second plane 2102, i.e., the protruding part 210131 is located at the edge (the side of the substrate 210 in the Z-axis direction) of the second plane 2102, and the protruding part 210131 protrudes from the substrate 210, so that when the third terminal 21013 is mounted on the second plane 2102, it can also contact the third contact pin 1103 through the protruding part 210131 to complete the electrical connection.

[0084] Preferably, the protruding part 210131 is bent on one side of the third terminal 21013, and when the third terminal 21013 is mounted on the second plane 2102, the protruding part 210131 is located on the side of the substrate 210 adjacent to the second plane 2102, specifically, the protruding part 210131 is located on the +Z side of the substrate 210, and the protruding part 210131 is located corresponding to the position of the third contact pin 1103 when the consumable cartridge 2 is mounted on the printing device 1, and can contact the side of the third contact pin 1103 in the Z-axis direction to receive or send information.

[0085] Alternatively, in some other embodiments, the third terminal 21013 can also not be provided on the substrate 210, and it can be provided on the front surface of the consumable cartridge 2 to be separated from other terminals.

[0086] Preferably, the part of the first terminal 21011 contacting the printing device 1 is a first contact part 210111, and the line connecting the first contact part 210111 and the protruding part 210131 is perpendicular to the first plane 2101, so that the protruding part 210131 can be tightly attached to the side of the substrate 210 on the substrate 210, and be more secure.

[0087] Preferably, the fifth terminal 21015 protrudes from the first plane 2101, and the fifth terminal 21015 can better contact the contact pin to avoid poor contact between the contact pin and the terminal due to metal fatigue causing insufficient elasticity. Specifically, the fifth terminal 21015 is connected to the first plane 2101 in a manner perpendicular to the second plane 2102, and the height of the fifth terminal 21015 protruding from the first plane 2101 is much higher than that of other terminals on the first plane 2101.

[0088] Preferably, all terminals in the terminal group are made of conductive material, so that when they contact the contact pin, they can be electrically connected to the contact pin to receive or send information.

[0089] Preferably, the third terminal 21013 and the fifth terminal 21015 can both be metal sheets, and when the consumable cartridge 2 is mounted on the printing device 1, they can rigidly contact the tip of the contact pin.

[0090] Next, the cooperation between the consumable chip 21 and the stylus of the printing device 1 when the consumable cartridge 2 is installed in the printing device 1 is described.

[0091] During use, the consumable cartridge 2 with the consumable chip 21 installed is linearly installed into the printing device 1 along the installation direction. Obviously, when the consumable cartridge 2 is installed into the printing device 1 along the negative direction of the Y axis from top to bottom, the first terminal 21011, the second terminal 21012, the fourth terminal 21014, and the fifth terminal 21015 on the substrate 210 correspond to the first stylus 1101, the second stylus 1102, the fourth stylus 1104, and the fifth stylus 1105 on the stylus holder 11 respectively, while the third stylus 1103 on the stylus holder 11 corresponds to the position of the side surface of the substrate 210.

[0092] After the consumable cartridge 2 is installed, the first stylus 1101, the second stylus 1102, and the fourth stylus 1104 contact the first terminal 21011, the second terminal 21012, and the fourth terminal 21014 of the consumable chip 21 respectively through the stylus tip, while the fifth stylus 1105 contacts the fifth terminal 21015 through the side surface of the stylus in the Z axis direction, thereby realizing the communication connection between the consumable cartridge 2 and the printing device 1. When the third stylus 1103 contacts the third terminal 21013, it contacts the protruding part 210131, and the side surface of the third stylus 1103 is located on the side of the +Z axis side of the substrate 210. When the fifth stylus 1105 contacts the fifth terminal 21015, it is located on the side of the -Z axis side of the fifth terminal 21015, so that the third stylus 1103 and the fifth stylus 1105 can be clamped on both sides of the consumable chip 21, preventing the consumable chip 21 from being displaced during installation and unable to form an effective electrical connection with the printing device 1.

[0093] It can be understood that the strokes of the first stylus 1101, the second stylus 1102, the third stylus 1103, the fourth stylus 1104, and the fifth stylus 1105 are inconsistent. In one case, the compression stroke of the first stylus 1101 is the largest. In addition, in some embodiments, the first contact part 210111 can also be a clamping contact part, and when the consumable cartridge 2 is installed in the printing device 1, the first stylus 1101 and the fifth stylus 1105 clamp the first contact part 210111 and the fifth terminal 21015, thereby limiting the displacement of the consumable chip 21.

[0094] In this embodiment, the consumable cartridge 2 and the consumable chip 21 have a third terminal 21013 disposed on the second plane 2102. This avoids the terminals on the consumable chip 21 being densely packed and having large gaps between them, making it less likely that when the user installs the consumable cartridge 2 on the printing device 1, the stylus of the printing device 1 will come into contact with a terminal whose function does not correspond to the consumable chip 21, causing a short circuit. In addition, the third terminal 21013 has a protrusion 210131 on the side of the substrate 210 to contact the third stylus 1103, and the fifth terminal 21015 is provided to protrude on the first plane 2101 to contact the fifth stylus 1105. This allows the third stylus 1103 and the fifth stylus 1105 to be used to grip the consumable chip 21, preventing the consumable chip 21 from shifting and failing to form an effective electrical connection with the printing device 1.

[0095] Example 2

[0096] like Figures 9 to 11 As shown, this embodiment provides another consumable chip 21. The difference between this embodiment and the first embodiment is that the third terminal 21013 does not protrude from the substrate 210 in this embodiment, and the third terminal 21013 does not have a protrusion 210131, but has a third contact portion 210132.

[0097] Specifically, such as Figure 11 As shown, in this embodiment, the third terminal 21013 has a structure that is basically the same as the other terminals, and is a flat plate structure, that is, the third terminal 21013 has a protrusion 210131 formed by bending. When the third terminal 21013 is installed on the second plane 2102, the third terminal 21013 and the second plane 2102 completely overlap.

[0098] Preferably, the third contact portion 210132 is provided as a portion of the third terminal 21013 that contacts the third stylus 1103 of the printing device 1, and the third contact portion 210132 also overlaps with the second plane 2102. Specifically, when the third terminal 21013 is mounted on the second plane 2102, it is located at the edge of the second plane 2102, and one side of the third terminal 21013 is flush with the side of the substrate 210 on the +Z axis side. This side of the third terminal 21013 is the third contact portion 210132, which is used to contact the third stylus 1103 to complete the electrical connection.

[0099] Preferably, the line connecting the third contact portion 210132 and the first contact portion 210111 is perpendicular to the first plane 2101.

[0100] Preferably, in this embodiment, the structures of the other terminals of the consumable chip 21 and the circuit module 21021 are basically the same as in Embodiment 1, and will not be described further here. Figure 12As shown, the fifth terminal 21015 protrudes from the first plane 2101; the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 are electrically connected to the circuit module 21021 through wires.

[0101] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable cartridge 2 is installed in the printing device 1 is described.

[0102] During use, after the consumable cartridge 2 with the consumable chip 21 installed is linearly installed into the printing device 1 in the installation direction, when the consumable cartridge 2 is installed into the printing device 1 from top to bottom along the negative direction of the Y axis, the first terminal 21011, the second terminal 21012, the fourth terminal 21014, and the fifth terminal 21015 on the substrate 210 correspond to the first contact pin 1101, the second contact pin 1102, the fourth contact pin 1104, and the fifth contact pin 1105 on the contact pin holder 11 respectively, while the third contact pin 1103 on the contact pin holder 11 corresponds to the position of the side of the substrate 210.

[0103] After the consumable cartridge 2 is installed, the first contact pin 1101, the second contact pin 1102, and the fourth contact pin 1104 respectively contact the first terminal 21011, the second terminal 21012, and the fourth terminal 21014 of the consumable chip 21 through the contact pin tips, while the fifth contact pin 1105 contacts the side of the fifth terminal 21015 through the side of the contact pin in the Z axis direction, thereby realizing the communication connection between the consumable cartridge 2 and the printing device 1, and when the third contact pin 1103 contacts the third terminal 21013, it contacts the third contact portion 210132, the side of the third contact pin 1103 is located on the side of the substrate 210 on the +Z axis side, and when the fifth contact pin 1105 contacts the fifth terminal 21015, it is located on the -Z axis side of the fifth terminal 21015, so that the third contact pin 1103 and the fifth contact pin 1105 can be clamped on both sides of the consumable chip 21 in the Z axis direction, preventing displacement of the consumable chip 21 during installation and forming an effective electrical connection with the printing device 1.

[0104] It can be understood that the strokes of 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 inconsistent. In one case, the compression stroke of the first contact pin 1101 is the largest. In some other embodiments, the first contact portion 210111 can also be a clamping contact portion, and when the consumable cartridge 2 is installed in the printing device 1, the first contact pin 1101 and the fifth contact pin 1105 clamp the first contact portion 210111 and the fifth contact portion 210151, thereby limiting displacement of the consumable chip 21.

[0105] In this embodiment, the other structures on the consumable box 2, the other structures on the consumable chip 21, and the structure of the printing device are the same as in Embodiment 1, and will not be described here again.

[0106] Example 3

[0107] like Figures 12 to 14 As shown, this embodiment provides another consumable chip 21. The difference between this embodiment and embodiment two is that in this embodiment, the fifth terminal 21015 does not protrude from the first plane 2101.

[0108] Specifically, such as Figure 14 As shown, in this embodiment, the fifth terminal 21015 has a structure that is basically the same as the other terminals, and is a flat plate structure. When the fifth terminal 21015 is installed on the second plane 2102, the installation method of the fifth terminal 21015 is the same as the installation method of the other terminals, and is installed in parallel on the first plane 2101, with the fifth terminal 21015 completely overlapping the first plane 2101.

[0109] Preferably, the fifth terminal 21015 further includes a fifth contact portion 210151 that contacts the third stylus 1103 of the printing device 1, and the fifth contact portion 210151 also overlaps with the first plane 2101. Specifically, when the fifth terminal 21015 is mounted on the first plane 2101, it is located at the edge of the first plane 2101, and one side of the fifth terminal 21015 is flush with the side of the substrate 210 on the -Z axis side. This side of the fifth terminal 21015 is the fifth contact portion 210151, which is used to contact the fifth stylus 1105 to complete the electrical connection.

[0110] The following section explains the interaction between the consumable chip 21 and the printing device 1 when the consumable cartridge 2 is installed in the printing device 1.

[0111] During use, the consumable cartridge 2 with the consumable chip 21 installed is linearly installed into the printing device 1 along the installation direction. When the consumable cartridge 2 is installed into the printing device 1 from top to bottom along the negative Y-axis, the first terminal 21011, the second terminal 21012 and the fourth terminal 21014 on the substrate 210 correspond to the first contact 1101, the second contact 1102 and the fourth contact 1104 on the contact pin holder 11, respectively. The third contact 1103 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the +Z axis side, and the fifth contact 1105 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the -Z axis side.

[0112] After the consumable cartridge 2 is installed, the first contact pin 1101, the second contact pin 1102, and the fourth contact pin 1104 are in contact with the first terminal 21011, the second terminal 21012, and the fourth terminal 21014 of the consumable chip 21 through the contact pin tip, respectively, while the fifth contact pin 1105 is in contact with the fifth contact part 210151 of the fifth terminal 21015 through the contact pin side, and the third contact pin 1103 is in contact with the third terminal 21013, and is in contact with the third contact part 210132, thereby realizing the communication connection between the consumable cartridge 2 and the printing device 1. The side of the third contact pin 1103 is located on the side of the substrate 210 on the +Z axis side, and the fifth contact pin 1105 is in contact with the fifth terminal 21015, and is located on the side of the substrate 210 on the -Z axis side, so that the third contact pin 1103 and the fifth contact pin 1105 can be clamped on both sides of the consumable chip 21, preventing displacement of the consumable chip 21 during installation and forming an effective electrical connection with the printing device 1.

[0113] It can be understood that the strokes of 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 inconsistent. In one case, the compression stroke of the first contact pin 1101 is the largest. In addition, in some other embodiments, the first contact part 210111 can also be a clamping contact part, and when the consumable cartridge 2 is installed in the printing device 1, the first contact pin 1101 and the fifth contact pin 1105 clamp the first contact part 210111 and the fifth contact part 210151, thereby limiting displacement of the consumable chip 21.

[0114] In this embodiment, other structures on the consumable cartridge 2, other structures on the consumable chip 21, and structures of the printing device are consistent with those in Embodiment Two, which will not be described here.

[0115] Embodiment Four

[0116] As shown in Figures 15 to 17 , another consumable chip 21 is provided in this embodiment, and the difference between this embodiment and Embodiment Three is that in this embodiment, the third terminal 21013 is provided with a protruding part 210131, that is, the difference between this embodiment and Embodiment One is that the fifth terminal 21015 is not protruding from the first plane 2101.

[0117] Referring to Figure 17 , when the third terminal 21013 is installed on the second plane 2102, the protruding part 210131 on the third terminal 21013 does not overlap the second plane 2102, that is, the protruding part 210131 is located at the edge of the second plane 2102, protruding from the substrate 210, so that when the third terminal 21013 is installed on the second plane 2102, it can also be in contact with the third contact pin 1103 through the protruding part 210131, and the electrical connection is completed.

[0118] Preferably, the protruding portion 210131 is bent from one side of the third terminal 21013, and is located on the side of the substrate 210 adjacent to the second plane 2102, specifically, the side of the substrate 210 on the +Z side, when the third terminal 21013 is installed on the second plane 2102. The protruding portion 210131 is located corresponding to the position of the third contact pin 1103, and can contact the third contact pin 1103 to receive or send information when the consumable cartridge 2 is installed in the printing device 1.

[0119] Preferably, the line connecting the protruding portion 210131 and the first contact portion 210111 is perpendicular to the first plane 2101.

[0120] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable cartridge 2 is installed in the printing device 1 is described.

[0121] The use process is that the consumable cartridge 2 with the consumable chip 21 installed is linearly installed into the printing device 1 along the installation direction. During the use process, the consumable cartridge 2 with the consumable chip 21 installed is linearly installed into the printing device 1 along the installation direction. When the consumable cartridge 2 is installed into the printing device 1 along the negative direction of the Y axis from top to bottom, the first terminal 21011, the second terminal 21012 and the fourth terminal 21014 on the substrate 210 correspond to the first contact pin 1101, the second contact pin 1102 and the fourth contact pin 1104 on the contact pin holder 11 respectively, and the third contact pin 1103 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the +Z axis side, and the fifth contact pin 1105 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the -Z axis side.

[0122] After the consumable cartridge 2 is installed, the first contact pin 1101, the second contact pin 1102 and the fourth contact pin 1104 contact the first terminal 21011, the second terminal 21012 and the fourth terminal 21014 of the consumable chip 21 through the contact pin tips respectively, and the fifth contact pin 1105 contacts the fifth contact portion 210151 of the fifth terminal 21015 through the side of the contact pin in the Z axis direction, and the third contact pin 1103 contacts the protruding portion 210131 when it contacts the third terminal 21013, thereby realizing the communication connection between the consumable cartridge 2 and the printing device 1. The side of the third contact pin 1103 is located on the side of the substrate 210 on the +Z axis side, and the fifth contact pin 1105 contacts the fifth terminal 21015, which is located on the side of the substrate 210 on the -Z axis side, so that the third contact pin 1103 and the fifth contact pin 1105 can be clamped on both sides of the consumable chip 21 in the Z axis direction, preventing displacement of the consumable chip 21 during installation and forming effective electrical connection with the printing device 1.

[0123] It is understandable that the extension and retraction strokes of 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 inconsistent. In one case, the first contact pin 1101 has the largest compression stroke. In addition, in some embodiments, the first contact portion 210111 can also serve as a clamping contact portion. When the consumable cartridge 2 is installed in the printing device 1, the first contact pin 1101 and the fifth contact pin 1105 clamp the first contact portion 210111 and the fifth terminal 21015, thereby preventing the consumable chip 21 from shifting.

[0124] In this embodiment, the other structures on the consumable box 2, the other structures on the consumable chip 21, and the structure of the printing device are the same as in Embodiment 1 or 3, and will not be described here again.

[0125] Example 5

[0126] like Figures 18 to 20 As shown, this embodiment provides another consumable chip 21. The difference between this embodiment and embodiments one, two, three or four is that the third terminal 21013 is disposed on the first plane 2101, while the fifth terminal 21015 is disposed on the second plane 2102.

[0127] Preferably, the fifth terminal 21015 is disposed on the second plane 2102 without protruding from the substrate 210, and the portion of the fifth terminal 21015 that contacts the third stylus 1103 of the printing device 1 is the fifth contact portion 210151. Specifically, in this embodiment, when the fifth terminal 21015 is mounted on the second plane 2102, the fifth terminal 21015 completely overlaps with the second plane 2102.

[0128] Preferably, the fifth contact portion 210151 also overlaps with the second plane 2102. Specifically, when the fifth terminal 21015 is mounted on the second plane 2102, it is located at the edge of the second plane 2102. One side of the fifth terminal 21015 is flush with the side of the substrate 210 on the -Z axis side. This side of the fifth terminal 21015 is the fifth contact portion 210151, which is used to contact the fifth contact pin 1105 to complete the electrical connection.

[0129] Preferably, in this embodiment, the structures of the other terminals of the consumable chip 21 and the circuit module 21021 are basically the same as in Embodiment 1, and will not be described further here. Figure 18 and Figure 20 As shown, the first terminal 21011, the second terminal 21012, the third terminal 21013, and the fourth terminal 21014 are all disposed on the first plane 2101. The first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 are electrically connected to the circuit module 21021 through wires.

[0130] Preferably, the third terminal 21013 is arranged on the first plane 2101 without protruding from the substrate 210, and the part of the third terminal 21013 that contacts the third contact pin 1103 of the printing device 1 is a third contact portion 210132.

[0131] Specifically, in the present embodiment, when the third terminal 21013 is mounted on the first plane 2101, the third terminal 21013 completely overlaps the first plane 2101, and the third terminal 21013 is substantially the same as other terminal structures, being a flat plate structure, i.e., the third terminal 21013 does not have a protruding portion 210131 formed by bending.

[0132] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable cartridge 2 is mounted on the printing device 1 is described.

[0133] During use, after the consumable cartridge 2 with the consumable chip 21 mounted thereon is linearly mounted into the printing device 1 along the mounting direction, when the consumable cartridge 2 is mounted into the printing device 1 from top to bottom along the negative direction of the Y axis, the first terminal 21011, the second terminal 21012, and the fourth terminal 21014 on the substrate 210 correspond to the first contact pin 1101, the second contact pin 1102, and the fourth contact pin 1104 on the contact pin holder 11 respectively, while the third contact pin 1103 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the +Z axis side, and the fifth contact pin 1105 on the contact pin holder 11 corresponds to the position of the side of the substrate 210 on the -Z axis side.

[0134] After the consumable cartridge 2 is mounted, the first contact pin 1101, the second contact pin 1102, and the fourth contact pin 1104 contact the first terminal 21011, the second terminal 21012, and the fourth terminal 21014 of the consumable chip 21 respectively through the contact pin tips, while the third contact pin 1103 contacts the side of the third terminal 21013 through the side of the contact pin in the Z axis direction, and the fifth contact pin 1105 contacts the fifth terminal 21015, and contacts the fifth contact portion 210151, thereby realizing the communication connection between the consumable cartridge 2 and the printing device 1. Moreover, the side of the third contact pin 1103 is located on the +Z axis side of the substrate 210, and when the fifth contact pin 1105 contacts the fifth terminal 21015, it is located on the -Z axis side of the fifth terminal 21015, so that the third contact pin 1103 and the fifth contact pin 1105 can be clamped on both sides of the consumable chip 21 in the Z axis direction, preventing displacement of the consumable chip 21 during installation and failure to form an effective electrical connection with the printing device 1.

[0135] It can be understood that the strokes of 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 inconsistent. In one case, the compression stroke of the first contact pin 1101 is the largest. In addition, in some other embodiments, the first contact part 210111 can also be a clamping contact part, when the consumable cartridge 2 is installed in the printing device 1, the first contact pin 1101 and the fifth contact pin 1105 clamp the first contact part 210111 and the fifth terminal 21015, so as to limit the displacement of the consumable chip 21.

[0136] In this embodiment, other structures on the consumable cartridge 2, other structures on the consumable chip 21 and structures of the printing device are consistent with those in Embodiments One, Two, Three or Four, which will not be described here.

[0137] Embodiment Six

[0138] As shown in Figures 21 to 23 , another consumable chip 21 is provided in this embodiment, and the difference between this embodiment and Embodiments One, Two, Three, Four or Five is that, in this embodiment, when the consumable chip 21 is installed and matched with the consumable cartridge 2, the consumable chip 21 is in an inclined state relative to the front surface 202 of the consumable cartridge, that is, the first plane 2101 and the second plane 2102 of the consumable chip 21 are not parallel to the front surface 202 of the consumable cartridge, but have a certain angle.

[0139] Referring to Figure 21 , the consumable cartridge 2 is provided with an auxiliary structure 2021 on the front surface 202 of the consumable cartridge, and the consumable chip 21 is installed on the auxiliary structure 2021 on the front surface 202 of the consumable cartridge, so that the consumable chip 21 is inclined on the front surface 202 of the consumable cartridge.

[0140] Specifically, in this embodiment, the auxiliary structure 2021 is a substantially right triangular prism structure, and the right side surface of the auxiliary structure 2021 is connected to the front surface 202 of the consumable cartridge, so that the auxiliary structure 2021 has a first auxiliary part 20211 and a second auxiliary part 20212 in the Z-axis direction, and the first auxiliary part 20211 and the second auxiliary part 20212 have an inclined surface (auxiliary plane 2023) therebetween, and the consumable chip 21 is installed on the inclined surface of the auxiliary structure 2021, at this time, the first auxiliary part 20211 is close to the first terminal 21011, and the second auxiliary part 20212 is close to the fifth terminal 21015.

[0141] Preferably, the first auxiliary part 20211 is in the height direction of the auxiliary structure 2021, and the height of the first auxiliary part 20211 is greater than that of the second auxiliary part 20212; or the height of the first auxiliary part 20211 is less than that of the second auxiliary part 20212. When the consumable chip 21 cooperates with the auxiliary structure 2021, because of the height difference between the first auxiliary part 20211 and the second auxiliary part 20212, the consumable chip 21 and the front surface 202 of the consumable box form an angle, which makes it more convenient for the stylus to hold the consumable chip 21.

[0142] Preferably, when the third terminal 21013 is arranged on the second plane 2102, the third terminal 21013 (clock contact part) cannot be seen from the front of the consumable chip 21, that is, when viewed from directly opposite the front surface 202 of the consumable box 2, the third terminal 21013 (clock contact part) cannot be seen.

[0143] Preferably, the second terminal 21012 and the fourth terminal 21014 are respectively provided with the second contact part 20121 and the fourth contact part 20141, which are in contact with the stylus.

[0144] As shown in Figures 22 to 26 , this embodiment provides another consumable chip 21, and the difference between this embodiment and embodiment six is that the structure of the auxiliary structure 2021 is different.

[0145] In this embodiment, the other structures on the consumable box 2, the structure of the consumable chip 21, and the structure of the printing device are the same as those in embodiments one, two, three, four, or five, and will not be described here.

[0146] Embodiment seven

[0147] As shown in Figure 27 , this embodiment provides another consumable chip 21, and the difference between this embodiment and embodiment six is that the structure of the auxiliary structure 2021 is different.

[0148] Referring to Figure 27 , the first auxiliary part 20211 and the second auxiliary part 20212 of the auxiliary structure 2021 are both strip-shaped protrusions arranged on the front surface 202 of the consumable box, and the consumable chip 21 is installed on the two strip-shaped protrusions and on the front surface 202 of the consumable box. The heights of the first auxiliary part 20211 and the second auxiliary part 20212 on the protrusions of the front surface 202 of the consumable box are different, so that there is a height difference between the first auxiliary part 20211 and the second auxiliary part 20212, and thus the consumable chip 21 and the front surface 202 of the consumable box form an angle.

[0149] Preferably, the first auxiliary part 20211 and the second auxiliary part 20212 are both protruded in the -X axis direction on the front surface 202 of the consumable box.

[0150] Preferably, the height of the first auxiliary part 20211 protrusion is greater than the height of the second auxiliary part 20212 protrusion.

[0151] It is understood that in some other embodiments, the height of the first auxiliary part 20211 protrusion may be less than the height of the second auxiliary part 20212 protrusion.

[0152] Preferably, when the consumable chip 21 is installed on the front surface 202 of the consumable box, the first auxiliary part 20211 is close to the first terminal 21011, and the second auxiliary part 20212 is close to the fifth terminal 21015.

[0153] In this embodiment, the structure of the consumable box 2 and the printing device 1 is the same as that described in Embodiment 6, and will not be described again here.

[0154] Example 8

[0155] like Figure 28 As shown, this embodiment provides another consumable chip 21. The difference between this embodiment and embodiment seven is that the structure of the auxiliary structure 2021 is different in this embodiment.

[0156] refer to Figure 28 The auxiliary structure 2021 is a groove structure that extends in a direction away from the front surface 202 of the consumable box.

[0157] Specifically, in this embodiment, the auxiliary structure 2021 further includes a third auxiliary part 20213 and a fourth auxiliary part 20214. The first auxiliary part 20211, the second auxiliary part 20212, the third auxiliary part 20213 and the fourth auxiliary part 20214 form a groove for accommodating the consumable chip 21. The first auxiliary part 20211 is close to the first terminal 21011, and the second auxiliary part 20212 is close to the fifth terminal 21015. The third auxiliary part 20213 and the fourth auxiliary part 20214 are used for limiting and preventing the consumable chip 21 from moving up and down in the direction of gravity. When the consumable chip 21 is engaged with the auxiliary structure 2021, due to the height difference between the first auxiliary part 20211 and the second auxiliary part 20212, the consumable chip 21 and the front surface 202 of the consumable box are at an angle.

[0158] In this embodiment, the structure of the consumable box 2 and the printing device 1 is the same as that described in Embodiment 7, and will not be described again here.

[0159] Example 9

[0160] like Figure 29 As shown, this embodiment provides another consumable chip 21. The difference between this embodiment and embodiments six, seven or eight is that the structure of the auxiliary structure 2021 is different in this embodiment.
