[0002] With the development of imaging technology, printing devices such as laser printers and inkjet printers have been widely used. During the printing process, the printing device completes the printing process with the assistance of the imaging auxiliary information of the consumable box.

[0070] like Figures 1 to 5 As shown, the printing device 1 provides consumables (such as ink and toner) for printing through the consumable box 2. The printing device 1 is provided with a communication port 10, and the consumable box 2 is provided with a consumable chip 21. Figure 1 As shown, 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, during the imaging process, the consumable chip 21 is used to provide identity recognition information and record material usage status information.

[0071] In this specification, in order to better describe the corresponding structure, the length direction of the consumable box 2 in the accompanying drawing is defined as the X-axis direction, the width direction of the consumable box is defined as the Z-axis direction, and the height direction of the consumable box (which is also the negative direction of the installation direction) is defined as the Y-axis direction.

[0072] like Figure 2 , Figure 4 As shown, the printing device 1 includes a stylus holder 11, which includes a plurality of styluses. The stylus holder 11 includes an upper end surface 111 of the stylus holder facing the Y axis, and a front end surface 112 of the stylus holder facing the X axis. The upper end surface 111 intersects with the front end surface 112. The stylus includes a stylus front end, a stylus tip, a stylus top end, and a stylus oblique end. The stylus tip is arranged on the front end surface, and the stylus top end is arranged on the upper end surface. When the consumable box is installed in the printing device, the front end face is arranged opposite to the front side wall of the consumable box, that is, the front end face faces the consumable box, and the multiple contact pins are specifically a first contact pin 1101, a second contact pin 1102, a third contact pin 1103, a fourth contact pin 1104 and a fifth contact pin 1105. When the consumable box 2 is installed in the printing device 1, the above-mentioned contact pins can respectively contact the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 (preferably, these terminals can be a data terminal SDA, a reset terminal RST, a clock terminal SCL, a power terminal VCC and a ground terminal GND) provided on the consumable chip 21.

[0073] like Figure 3 As shown, the structures 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 in the plurality of contact pins are all the same. Now, the first contact pin 1101 is taken as an example for description. The first contact pin 1101 includes a first contact pin top 11011, a first contact pin front end 11012, a first contact pin oblique end 11013 and a first contact pin tip 11014. The first contact pin top 11011, the first contact pin front end 11012, the first contact pin oblique end 11013 and the first contact pin tip 11014 can all form contact with the terminals on the consumable chip and be electrically connected. In this way, the consumable chip 21 of the consumable box 2 can realize the communication process with the printing device 1 through the contact pins.

[0074] The upper end surface 111 of the contact pin holder also includes a first slit 1111, a second slit 1112, a third slit 1113, a fourth slit 1114 and a fifth slit 1115. The first contact pin 1101, the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 are respectively arranged in the first slit 1111, the second slit 1112, the third slit 1113, the fourth slit 1114 and the fifth slit 1115 of the contact pin holder 11, and are all in contact with 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 through the contact pin tips arranged on the front end surface 112 of the contact pin holder. The printing device 1 sends a data signal to the consumable chip 21 through the first terminal 21011, the printing device 1 sends a reset signal to the consumable chip 21 through the second terminal 21012, the printing device 1 sends a periodic low-level and high-level alternating and repeated clock signal to the consumable chip 21 through the third terminal 21013, the printing device 1 provides a working voltage for the consumable chip 21 through the fourth terminal 21014, and the printing device 1 provides a unified reference low level for receiving and sending data between the printing device 1 and the consumable chip 21 through the fifth terminal 21015, thereby ensuring the correctness and stability of the communication process.

[0075] The terminals of the consumable chip 21 are arranged in two rows, with a small gap between the terminals. Preferably, the first terminal 21011 and the second terminal 21012 are arranged in the upper row, and the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 are arranged in the lower row.

[0076] However, since the terminals on the consumable chip 21 of the prior art (the above-mentioned setting) are relatively dense and the gaps between the terminals are small, it is easy for the contact pins of the printing device 1 to contact terminals that do not correspond to their functions when the user installs the consumable box 2 on the printing device, causing a short circuit; in addition, the consumable chip is easily displaced downward during this process and cannot form an effective electrical connection with the printing device.

[0077] Therefore, an embodiment of the present application provides a solution for redesigning the terminals of a consumable chip.

[0078] Embodiment 1

[0079] like Figures 6 to 16 As shown, Figure 6A schematic diagram of a consumable chip 21 provided in this embodiment. In the consumable chip 21 in this embodiment, the fifth terminal 21015 is set on the consumable box 2, and the fifth terminal 21015 is separated from other terminals, which solves the problem that the consumable chip 21 may be offset, causing the ground terminal at the edge position to be unable to form a normal electrical connection with the contact pin of the printing device 1, resulting in the inability to provide a unified reference low level for receiving and sending data between the printing device 1 and the consumable chip 21, and the correctness and stability of the communication process cannot be guaranteed.

[0080] like Figure 6 to Figure 7 As shown, a consumable chip 21 includes a substrate 210, a terminal group arranged on the substrate 210, and a storage module 21021.

[0081] The substrate 210 has a first surface 2101 and a second surface 2102 that are arranged opposite to each other. The first surface 2101 is provided with a terminal group to form an electrical connection with the tip of the contact pin, and the second surface 2102 is used to contact the consumable box 2.

[0082] The terminal group includes a plurality of terminals, all of which are disposed on the first surface 2101 of the substrate, specifically a first terminal 21011 , a second terminal 21012 , a third terminal 21013 and a fourth terminal 21014 disposed on the first surface 2101 of the substrate 210 .

[0083] like Figure 7 As shown, the second surface 2102 of the substrate 210 is further provided with a connecting portion 22a. Figure 8 As shown, the consumable box 2 includes a front side wall 211, a left side wall 212, and a right side wall (not shown) opposite to the left side wall 212, wherein the front side wall 211 is located at the rear of the consumable box in the X-axis direction, and the left side wall 212 and the right side wall are located on the left and right sides of the consumable box 2 in the Z-axis direction.

[0084] like Figure 8 , Fig. 9 As shown, the consumable chip 21 is mounted on the front side wall 211 of the consumable box 2, and a fifth terminal 21015 is also provided on the front side wall 211 of the consumable box 2. The fifth terminal 21015 can be electrically connected to the connecting portion 22a on the second surface 2102 of the consumable chip 21 through the conductive portion 2112. Preferably, the conductive portion 2112 can be a wire. Alternatively, refer to Fig. 9In some other embodiments, the conductive part may also be a conductive member, and the material of the conductive member may be a metal conductive sheet. Alternatively, in other embodiments, the conductive member may be formed by first digging a first groove on the consumable box 21, and pouring the conductive part 2112 into the first groove by injection molding or glue injection. The specific material of the conductive part 2112 may be a conductive plastic or rubber material, and the fifth terminal 21015 is electrically connected to the connecting part 22a on the second surface 2102 of the consumable chip 210 through the conductive part 2112.

[0085] The storage module is arranged on the substrate 210. Preferably, the storage module can be arranged on the second surface 2102 of the substrate 210, and the storage module stores information such as the manufacturer information, the amount of consumables information, the category information, and the color of the consumable box 2. The first terminal 21011, the second terminal 21012, the third terminal 21013, and the fourth terminal 21014 and the connecting portion 22a are all electrically connected to the storage module, so as to facilitate the consumable chip 21 to complete the corresponding work and realize the corresponding function. When the terminal is connected to the contact pin, the printing device 1 can read the consumable box information stored in the storage module.

[0086] It should be noted that the storage module can theoretically be arranged on any surface of the substrate 210 , but since the layout area of ​​the substrate 210 is limited, it is a preferred design to arrange the storage module on the second surface 2102 or inside the substrate 210 .

[0087] Preferably, the fifth terminal 21015 may be a metal sheet arranged on the front side wall of the consumable box 2 , and when the consumable box 2 is installed in the printing device 1 , the fifth terminal 21015 is in rigid contact with the stylus tip of the stylus.

[0088] Or, if Fig.12 , Fig.13 and Fig.14 As shown, in some other embodiments, the fifth terminal 21015 may also protrude from the front side wall 211 on the consumable box 2. When the consumable box 2 is installed on the printing device 1, the fifth terminal 21015 contacts the front end of the ground contact pin 1105 of the printing device 1 and is electrically connected to the storage module through the conductive part 2112.

[0089] Or, if Fig.15 , Fig.16 As shown, in some other embodiments, the fifth terminal 21015 can move relative to the front side wall 211 on the consumable box 2, that is, the fifth terminal 21015 can move along the direction opposite to the X-axis of the consumable box installation position.

[0090] It is worth noting that since the first surface 2101 of the substrate 210 only needs to be provided with the first terminal 21011, the second terminal 21012, the third terminal 21013 and the fourth terminal 21014, the size of the substrate 210 in the Z-axis direction can be smaller than the size of the substrate 210 in the prior art.

[0091] Next, the cooperation between the consumable chip 21 and the contact pins of the printing device 1 when the consumable box 2 is installed in the printing device 1 is described.

[0092] refer to Fig.11 Obviously, when the consumable box 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 third terminal 21013 and the fourth terminal 21014 on the substrate 210 correspond to the first contact pin 1101, the second contact pin 1102, the third contact pin 1103 and the fourth contact pin 1104 on the contact pin holder 11 respectively, and the fifth contact pin 1105 on the contact pin holder 11 corresponds to the fifth terminal 21011 on the consumable box 2. Corresponding to the position of 21015, after the consumable box 2 is installed, the first contact pin 1101, the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 are respectively in contact with the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 of the consumable chip 21 through the tip of the contact pin, thereby realizing the communication connection between the consumable box 2 and the printing device 1.

[0093] It should be noted that, in this embodiment, the terminal provided on the consumable box 2 is not limited to the fifth terminal 21015, and may also be one or more of the first terminal 21011, the second terminal 21012, the third terminal 21013 and the fourth terminal 21014, which is not limited here.

[0094] There is no restriction on the positions of the conductive portion 2112 and the fifth terminal 21015 on the consumable box 2 , and there is no restriction on the position of the connecting portion 22 a on the consumable chip 21 , as long as they can contact the conductive portion 2112 .

[0095] The consumable box 2 and the consumable chip 21 in this embodiment fix the fifth terminal 21015 on the consumable box 2, so that when the consumable box 2 is installed on the printing device 1, even if the consumable chip 21 is offset, the fifth terminal 21015 and the contact pin of the printing device 1 can form a stable connection. At the same time, the position of the fifth terminal 21015 fixed to the consumable box 2 can be more flexible, so that the fifth terminal 21015 can contact different structures of the contact pin of the printing device 1, thereby enhancing the stability of the connection.

[0096] The above embodiments make a certain terminal away from other terminals. When the consumable chip moves, it will not affect the effective electrical connection between a certain terminal and the printing device. Then the following embodiments can stabilize the consumable chip and prevent it from moving downward as a whole.

[0097] Embodiment 2

[0098] like Fig.17 As shown, another consumable chip 21 is provided in this embodiment. The difference between this embodiment and embodiment 1 is that the consumable chip 21 provided in this embodiment includes a substrate 210, a terminal group and a storage module 21021 arranged on the substrate 210, and a connecting portion 22b. In this embodiment, the connecting portion 22b serves as a structure that abuts against the contact pin.

[0099] In this embodiment, the structure of the terminal group of the consumable chip 21 and the storage module 21021 is basically the same as that of the first embodiment, and will not be described here. The difference is that the size of the substrate 210 is longer and the structure and position of the connecting portion 22b are different. The connecting portion 22b is used to connect the storage module 21021 and abut against the top of the contact pin. The length of the substrate 210 is H, which is roughly the same as the height L of the contact pin holder.

[0100] like Fig.17 As shown, the connecting portion 22b is arranged on the first surface 2101 of the substrate 210, the connecting portion 22b is electrically connected to the storage module 21021, and protrudes from the first surface, and a connecting terminal is provided on the connecting portion 22b. When the consumable box 2 is installed on the printing device 1, the connecting terminal can replace any one or more of the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 to abut against the top of the contact pin on the printing device 1, thereby realizing the electrical connection between the storage module 21021 and the printing device 1.

[0101] In some embodiments, the connection terminal includes a first connection terminal 222b and a second connection terminal 223b, that is, the connection portion 22b includes a connection portion body 221b, a first connection terminal 222b and a second connection terminal 223b, the connection portion body 221b is welded or clamped on the first surface 2101 of the substrate 210, and the first connection terminal 222b and the second connection terminal 223b protrude from the connection portion body 221b. Since the first connection terminal 222b and the second connection terminal 223b have a certain length, a protective portion that matches them can be provided on the consumable box to wrap the first connection terminal 222b and the second connection terminal 223b to prevent the user from being stabbed by the protruding connection portion 22b.

[0102] The terminal group on the substrate 210 is provided with three terminals, specifically a third terminal 21013 , a fourth terminal 21014 and a fifth terminal 21015 .

[0103] The storage module 21021 is disposed on the second surface 2102 of the substrate 210, and the first connection terminal 222b, the second connection terminal 223b, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 are all electrically connected to the storage module 21021. Preferably, the first connection terminal 222b, the second connection terminal 223b, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 are all electrically connected to the storage module 21021 through wires (not shown in the drawings).

[0104] When the first connecting terminal 222b protrudes from the connecting part body 221b, its front end is the first abutting portion 2221b, and when the second connecting terminal 223b protrudes from the connecting part body 221b, its front end is the second abutting portion 2231b, and the first abutting portion 2221b of the first connecting terminal 222b and the second abutting portion 2231b of the second connecting terminal 223b are opposite to the upper end surface 111 of the contact pin holder. When the consumable box 2 is installed on the printing device 1, the first connecting terminal 222b abuts against the contact pin top 11011 of the first contact pin 1101 through the first abutting portion 2221b, and the second connecting terminal 223b abuts against the contact pin top 11021 of the second contact pin 1102 through the second abutting portion 2231b, so that the connecting terminal is electrically connected to the contact pin, and the storage module 21021 is electrically connected to the printing device 1.

[0105] It should be noted that the above-mentioned contact mode may be that both the first abutting portion 2221b and the second abutting portion 2231b include an elastic structure (not shown), and are in contact with the rigid first contact pin 1101 and the second contact pin 1102, respectively. Specifically, it may be a line contact, that is, the elastic structure wraps the first contact pin 1101 or the second contact pin 1102. Alternatively, in some other embodiments, the above-mentioned contact mode may also be a point contact, that is, the elastic structure is an elastic protrusion on the first abutting portion 2221b and the second abutting portion 2231b, and the elastic protrusion forms a point contact with the rigid first contact pin 1101 or the second contact pin 1102. Alternatively, in some other embodiments, the above-mentioned contact mode may also be that both the first abutting portion 2221b and the second abutting portion 2231b are rigid, and are in contact with the first contact pin 1101 and the second contact pin 1102, which are also rigid. This is not limited here. A large resistor or other device is included between the first connection terminal 222b and the second connection terminal 223b to prevent the two from being short-circuited. When sending or receiving a signal from the printing device 1, the two do not interfere with each other.

[0106] In some embodiments, in order to make the contact pins on the contact pin holder 11 correspond to the terminals on the consumable chip 21 , the length H of the consumable chip 21 is substantially equal to the height L of the contact pin holder 11 .

[0107] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable box 2 is installed in the printing device 1 is described.

[0108] During use, after the consumable box 2 with the consumable chip 21 installed is linearly installed in the printing device 1 along the installation direction, 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 on the contact pin holder 11 of the printing device 1 correspond to the first connection terminal 222b, the second connection terminal 223b, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 on the substrate 210, respectively. As the consumable box 2 is installed, the contact pin tips of the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 on the contact pin holder 11 abut against the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 on the substrate 210 to form an electrical connection. The first connection terminal 222b and the second connection terminal 223b abut against the contact pin tips of the first contact pin 1101 and the second contact pin 1102 to form an electrical connection.

[0109] In this embodiment, the first connection terminal 222b and the second connection terminal 223b are far enough away from other terminals on the consumable chip 21, so that the tip of the third contact pin 1103 on the printing device 1 will not easily cause the third contact pin 1103 to contact other terminals and cause a short circuit when the contact pin passes through other terminals by mistake during the installation of the consumable box 2, as in the prior art. In addition, since the connecting portion protrudes from the substrate, it has a limiting effect on the contact pin holder. When the consumable box is installed on the printing device and the consumable chip moves downward, the connecting portion can clamp the upper end surface of the contact pin holder to prevent the consumable chip from moving downward.

[0110] Embodiment 3

[0111] like Fig.18 As shown, another consumable chip 21 is provided in this embodiment. The difference between this embodiment and the second embodiment is that: in this embodiment, the connecting portion 22c has only one connecting terminal, and the connecting terminal contacts the top of any contact pin of the contact pin holder 11.

[0112] Specifically, in this embodiment, the connection terminal includes a first connection terminal 222c, that is, the connection part body 221c is provided with a protrusion, and the first connection terminal 222c includes a first abutting portion 2221c, and the first abutting portion 2221c contacts the contact pin tip 11011 of the first contact pin 1101.

[0113] There are four terminals on the substrate 210 , specifically a second terminal 21012 , a third terminal 21013 , a fourth terminal 21014 and a fifth terminal 21015 .

[0114] When the consumables box 2 is installed on 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 on the contact pin holder 11 of the printing device 1 correspond to the first connection terminal 222c, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 respectively. With the installation of the consumables box 2, the contact pin tips of the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104 and the fifth terminal 21015 on the substrate 210 are respectively contacted to form an electrical connection. At this time, the first connection terminal 222c abuts against the contact pin tip 11011 of the first contact pin 1101 on the contact pin holder 11 to form an electrical connection.

[0115] Embodiment 4

[0116] like Figures 19 to 24 As shown, another consumable chip is provided in this embodiment. The substrate 210 and the connecting portion 22d of the consumable chip 21 in this embodiment are different from those in the second and third embodiments.

[0117] See also Fig.19 , Fig. 20 The terminal group on the consumable chip 21 includes a second terminal 21012, a third terminal 21013, a fourth terminal 21014 and a fifth terminal 21015 arranged on the first surface 2101 of the substrate 210, the first terminal 21011 is an edge terminal in the terminal group, and the connecting portion 22d is electrically connected to the storage module 21021 through the edge terminal.

[0118] The storage module 21021 is also disposed on the second surface 2102 of the substrate 210. 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 storage module 21021. Preferably, all the terminals are electrically connected to the storage module 21021 through wires. Fig.21 and Fig. 22 The connecting portion 22 d is arranged on the consumable box 2 . Preferably, the connecting portion 22 d and the base plate 210 are also arranged on the front side wall 211 of the consumable box 21 .

[0119] The connecting portion 22d includes an extending portion 221d and a conductive portion 222d. Fig.23As shown, the extension portion 221d includes a contact surface 2211d facing the negative direction of the Y-axis. On the consumable box 2, the connecting portion 22d is located above the substrate 210. One end of the conductive portion 222d is connected to the extension portion 221d, and the other end extends to the substrate 210 to connect to the first terminal 21011 of the substrate 210, which is used to electrically connect the substrate 210 with the extension portion 221d.

[0120] The connection method between the connecting portion 22d and the first terminal 21011 on the substrate 210 can be: the connecting portion 22d is detachably mounted on the consumable box 2, and then the substrate 210 is mounted on the front side wall 211 of the consumable box 2, and the position of the first terminal 21011 of the substrate 210 corresponds to one end of the conductive portion 222d in the connecting portion 22d, so that when the substrate 210 is installed, the first terminal 21011 can form an electrical connection with the connecting portion 22d, and the other end of the connecting portion 22d is outside the substrate, so that the connecting portion 22d can transmit data signals. In some other embodiments, the connecting portion 22d can also be welded or clamped with the substrate 210 to form a consumable chip 21 as a whole, and then the consumable chip 21 is detachably mounted on the consumable box 2.

[0121] Furthermore, the extension portion 221d of the connection portion 22d protrudes in the X-axis direction on the front side wall 211 of the consumable box 2, so that when the consumable box 2 is installed in the printing device 1, the extension portion 221d can be used to abut against the top of the stylus to make an electrical connection. Specifically, when the consumable box 2 is installed in the printing device 1, the abutting surface 2211d of the connection portion 22d is opposite to the upper end surface 111 of the stylus holder, and the top of the stylus is flush with the upper end surface or higher than the upper end surface 111 of the stylus holder, so that the top of the stylus of the printing device 1 abuts against the abutting surface 2211d provided on the extension portion 221d, forming Fig. 22 The contact portion C shown realizes electrical connection.

[0122] Preferably, the contact between the abutting surface 2211d and the top of the stylus may be that an elastic structure (not shown) is provided on the abutting surface 2211d and contacts the rigid stylus, specifically, it may be line contact, that is, the elastic structure wraps the stylus to form a contact portion C. Alternatively, in some other embodiments, the contact between the abutting surface 2211d and the top of the stylus may be point contact, that is, the elastic structure is an elastic protrusion on the abutting surface 2211d, and the protrusion forms a point contact with the rigid stylus.

[0123] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable box 2 is installed in the printing device 1 is described.

[0124] refer to Fig.24The use process is as follows: the consumable box 2 with the consumable chip 21 installed is linearly installed in the printing device 1 along the installation direction, and the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 on the contact pin holder 11 of the printing device 1 correspond to the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 on the substrate 210 respectively, and the first contact pin 1101 corresponds to the abutting surface 2211d of the connecting portion 22d. As the consumable box 2 is installed, the contact pin tips of the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 on the contact pin holder 11 respectively abut against the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 on the substrate 210 to form an electrical connection. At this time, the contact pin tip 11011 of the first contact pin 1104 contacts the contact surface 2211d on the extension portion 221d to form an electrical connection, so that the consumable box 2 is connected to the printing device 1 for communication when installed.

[0125] In this embodiment, the first terminal 21011 is arranged on the second surface 2102 of the substrate 210, and is connected to the contact pin on the contact pin holder 11 through the connecting portion 22d, so that the distance between the first terminal 21011 and the other terminals is far enough, and the contact pin tips of other contact pins will not, like in the prior art, easily cause the clock contact pin to contact the first terminal 21011 and cause a short circuit when the tip of the clock contact pin accidentally passes through the first terminal 21011 during the installation of the consumable box 2, thereby affecting the transmission of the data signal.

[0126] Embodiment 5

[0127] like Fig.24 As shown, another consumable chip 21 is provided in this embodiment. The difference between this embodiment and embodiment 4 is that: compared with embodiment 4, the extension portion 221 of this embodiment also includes a shielding portion 2212e, and when the consumable box 1 is installed in the printing device 1, the shielding portion 2212e shields dust or other pollutants from the printing device 1.

[0128] Specifically, refer to Fig.24 In this embodiment, the shielding portion 2212e is arranged on a side of the extension portion 221d away from the conductive portion 222d, and the shielding portion 2212e extends along the Y-axis and bends toward the X-axis. When the consumable box 2 is installed on the printing device 1, the shielding portion 2212e is on the outer side of the upper end surface of the stylus holder 11, and is used to shield dust or other contaminants from the printing device 1.

[0129] In this embodiment, the structures of the printing device and the consumables box are consistent with those described in Implementation 4 and will not be described again here.

[0130] Embodiment 6

[0131] like Figure 25 to Figure 28 As shown, another consumable chip 21 is provided in this embodiment. The difference between this embodiment and embodiment 4 is that: in this embodiment, there are two outer edge terminals arranged on the second surface 2102 of the substrate 210, and both outer edge terminals are abutted against the contact pins on the printing device 1 through the connecting portion 22f to complete the electrical connection with the printing device 1.

The conductive portion 222f of the connecting portion 22f is provided with a fork at one end of the connecting substrate 210. When the connecting portion 22f is connected to the substrate 210, the forked position of the conductive portion 222f can respectively connect the second terminal 21012 and the first terminal 21011, so that the second terminal 21012 and the first terminal 21011 can be electrically connected to the printing device 1 through the connecting portion 22e.

[0133] pass Fig.28 It can be seen that in this embodiment, the number of terminals disposed on the first surface 2101 of the substrate 210 is reduced, the size of the substrate 210 can be smaller, and the material of the substrate 210 can be effectively saved.

As the consumable box 2 is installed, the contact pin tips of the third contact pin 1103, the fourth contact pin 1104 and the fifth contact pin 1105 on the contact pin holder 11 contact the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015 on the substrate 210 respectively to form an electrical connection. At this time, the contact pin tip 11011 of the first contact pin 1101 and the contact pin tip 11021 of the second contact pin 1102 both abut against the abutment surface 2211f on the extension portion 221f to form contact portions C and D, so that the consumable box 2 transmits data signals and reset signals to the printing device 1 respectively when installed.

[0135] It should be noted that the terminal arranged on the second surface 2102 of the substrate 210 can also be any one or more of the first terminal 21011, the second terminal 21012, the third terminal 21013, the fourth terminal 21014 and the fifth terminal 21015, which are connected to the connecting part 22f arranged on the second surface 2102 of the substrate 210, and then the connecting part 22f is abutted against the top of the contact pin of the contact pin to realize the electrical connection between the storage module 21021 and the printing device 1.

[0136] In this embodiment, the structures of the printing device and the consumables box are consistent with those described in Implementation 4 and will not be described again here.

[0141] like Fig.31 As shown, the connection terminal includes a connection body 221g, a first connection terminal 222g, and a second connection terminal 223g. The connection body 221g is welded or clamped on the first surface 2101 of the substrate 210. The first connection terminal 222g and the second connection terminal 223g protrude from the connection body 221g. The terminal group includes a first terminal 21011, a second terminal 21012, a third terminal 21013, a fourth terminal 21014, a fifth terminal 21015, a sixth terminal 21016, and a seventh terminal 21017 arranged on the first surface. The storage module 21021 is arranged on the second surface 2102 of the substrate 210. 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 storage module 21021. The first connection terminal 222g and the second connection terminal 223g are not electrically connected to the storage module 21021, but the first connection terminal 222g and the second connection terminal 223g are short-circuited with each other, and are used to pass the current through the first connection terminal 222g and the second connection terminal 223g when the first connection terminal 222g and the second connection terminal 223g are in contact with the corresponding contact pins, so as to detect whether the consumable chip is correctly installed; or connect the short circuit detection unit of the printing device through the first connection terminal 222g and the second connection terminal 223g to detect whether the consumable chip is short-circuited. The sixth terminal 21016 (first high-voltage terminal A) and the seventh terminal 21017 (second high-voltage terminal B) are not connected to the storage module, but are applied with high voltage to realize other functions such as ink volume detection.

[0144] In some embodiments, in order to make the contact pins on the contact pin holder 11 correspond to the terminals on the consumable chip 21, the length H of the consumable chip 21 is substantially equal to the height L of the contact pin holder.

[0145] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable box 2 is installed in the printing device 1 is described.

[0146] During use, the consumable box 1 with the consumable chip 21 installed is linearly installed in the printing device 1 along the installation direction, and the second contact pin 1102, the third contact pin 1103, the fifth contact pin 1105, the sixth contact pin 1106, the seventh contact pin 1107, the eighth contact pin 1108 and the ninth contact pin 1109 on the contact pin holder 11 of the printing device 1 are respectively connected to the second terminal 21012 (reset terminal), the third terminal 21013 (clock terminal), the sixth terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21015 (ground terminal GND), the first terminal 21011 (data terminal SDA) and the seventh terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21015 (ground terminal GND), the first terminal 21011 (data terminal SDA) and the seventh terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21016 (ground terminal GND), the first terminal 21011 (data terminal SDA) and the seventh terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21015 ... second terminal 21011 (data terminal SDA) and the seventh terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21015 (ground terminal GND Corresponding to the position of 1017 (second high-voltage terminal B), with the installation of the consumable box 2, the contact pin tips of the second contact pin 1102, the third contact pin 1103, the fifth contact pin 1105, the sixth contact pin 1106, the seventh contact pin 1107, the eighth contact pin 1108 and the ninth contact pin 1109 on the contact pin holder 11 are respectively in contact with the second terminal 21012, the third terminal 21013, the sixth terminal 21016 (first high-voltage terminal A), the fourth terminal 21014 (power terminal VCC), the fifth terminal 21015 (ground terminal GND), the first terminal 21011 (data terminal SDA) and the seventh terminal 21017 (second high-voltage terminal B) on the substrate 210 to form an electrical connection.

[0147] At this time, the first connection terminal 222g and the second connection terminal 223g respectively abut against the contact pin tips of the first contact pin 1101 and the fourth contact pin 1104 through the first abutting portion 2221g and the second abutting portion 2231g to form an electrical connection.

[0148] Embodiment 8

[0149] like Figure 32 to Figure 35 As shown, another consumable chip 21 is provided in this embodiment. The difference between this embodiment and embodiment seven is that the structure of the connecting part 22h in this embodiment is different. Taking the connecting part 22h as a short circuit detection connecting part as an example, the consumable chip 21 includes a substrate 210, a terminal group, a storage module 21021 and a connecting part 22h.

[0150] The terminal group includes a second terminal 21012 (reset terminal RST), a third terminal 21013 (clock terminal SCL), a sixth terminal 21016 (first high voltage terminal A), a fourth terminal 21014 (power supply terminal VCC), a fifth terminal 21015 (ground terminal GND), a first terminal 21011 (data terminal SDA) and a seventh terminal 21017 (second high voltage terminal B) arranged on the first surface 2101 of the substrate 210, and the second surface 2102 of the substrate 210 includes a storage module 21021, a first short circuit detection terminal 21022 and a second short circuit detection terminal 21024. The second terminal 21012 (reset terminal RST), the third terminal 21013 (clock terminal SCL), the fourth terminal 21014 (power supply terminal VCC), the fifth terminal 21015 (ground terminal GND), and the first terminal 21011 (data terminal SDA) are all electrically connected to the storage module 21021.

[0151] The connection part 22h is a short circuit detection connection part, specifically a first short circuit detection connection part 221h and a second short circuit detection connection part 222h, and one end of the first short circuit detection connection part 221h and the second short circuit detection connection part 222h are both connected to the second surface 2102 of the substrate 210. Preferably, the first short circuit detection connection part 221h and the second short circuit detection connection part 222h are clamped or welded to the second surface 2102 of the substrate 210, so that production integration can be achieved, and the user only needs to install the first short circuit detection connection part 221h, the second short circuit detection connection part 222h and the substrate 210 as a whole on the consumable box 2. Alternatively, in another practicable manner, the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h may not be welded to the second surface 2102, but are two independent entities from the substrate 210, and the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h are detachably mounted on the consumable box 2, and then the substrate 210 is mounted, and since the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h are not connected to the storage module 21021, the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h do not need to be aligned with the first short-circuit detection terminal 21022 and the second short-circuit detection terminal 21024 of the substrate 210. If the connection portion 22h replaces other terminals that perform communication functions, it needs to be aligned with the terminals set on the second surface 2102 of the substrate 210 to achieve communication with the storage module.

[0152] Furthermore, an embedding portion and a contact portion are provided at the other end of the connection portion 22h that is not connected to the substrate 210. Specifically, the first short-circuit detection connection portion 221h is provided with a first embedding portion 2211h, a first contact portion 2212h, and a second embedding portion 2213h at the end that is not connected to the substrate; the second short-circuit detection connection portion 222h is provided with a third embedding portion 2221h, a second contact portion 2222h, and a fourth embedding portion 2223h at the end that is not connected to the substrate. Through the first contact portion 2212h and the second contact portion 2222h, the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h are brought into contact with the top end of the contact pin on the printing device 1 to form an electrical connection.

[0153] In some embodiments, the length of the consumable chip 21 is substantially equal to the height H of the stylus holder 11 , which can effectively reduce the lengths of the first short circuit detection connection portion 221h and the second short circuit detection connection portion 222h.

[0154] In some embodiments, the length L of the substrate 210 of this embodiment is consistent with the length L1 of the consumable chip 21 of the prior art (such as the first embodiment). The length L of the substrate 210 plus the length L2 of the first short circuit detection connection portion 221h is substantially equal to the height H of the stylus holder 11 in the seventh embodiment.

[0155] Next, the cooperation between the consumable chip 21 and the printing device 1 when the consumable box 2 is installed in the printing device 1 is described.

[0156] See also Fig.34 , Fig.35 When the consumable chip 21 is installed in the consumable box 2 and then installed in the printing device 1, the front side wall 211 of the consumable box 2 is opposite to the front end surface 112 of the contact pin holder, and the second terminal 21012 (reset terminal RST), the third terminal 21013 (clock terminal SCL), the sixth terminal 21016 (first high voltage terminal A), the fourth terminal 21014 (power terminal VCC), the fifth terminal 21015 (ground terminal GND), the first terminal 21011 (data terminal SDA) and the seventh terminal 21017 (second high voltage terminal B) of the substrate 210 of the consumable chip 21 are respectively abutted against the contact pin tips of the second contact pin 1102, the third contact pin 1103, the fifth contact pin 1105, the sixth contact pin 1106, the seventh contact pin 1107, the eighth contact pin 1108 and the ninth contact pin 1109 on the contact pin holder 11 for electrical connection.

[0157] At this time, the first embedding portion 2211h and the second embedding portion 2213h of the first short-circuit detection connection portion 221h are respectively embedded in Fig.29The first slit 1111 and the second slit 1112 of the stylus holder 11 are shown, and the third embedding portion 2221h and the fourth embedding portion 2223h of the second short-circuit detection connection portion 222h are respectively embedded in the third slit 1113 and the fourth slit 1114 of the stylus holder 11, so that the first short-circuit detection connection portion 221h and the second short-circuit detection connection portion 222h are stably electrically connected to the printing device 1. The first contact portion 2212h and the second contact portion 2222h are respectively in contact with the first stylus 1101 and the fourth stylus 1104.

[0158] It should be noted that, in one implementation, the first contact portion 2212h of the first short circuit detection connection portion 221h and the second contact portion 2222h of the second short circuit detection connection portion 222h are elastic and can undergo elastic deformation in the vertical direction to elastically contact the first contact pin 1101 and the second contact pin 1104 respectively.

[0159] Alternatively, in another implementation, the first contact portion 2212h and the second contact portion 2222h may be rigid and rigidly contact the first contact pin tip 11011 of the first contact pin 1101 and the second contact pin tip 11041 of the second contact pin 1104 respectively.

[0160] Obviously, in this embodiment, the first short-circuit detection connection part 221h and the second short-circuit detection connection part 222h are provided with an embedded part that can be stably installed with the stylus holder 11, so as to prevent the consumable chip 21 from being displaced on both sides above after the consumable box 2 is installed in the printing device 1, causing the short-circuit detection terminal of the prior art to deviate from the two short-circuit detection stylus pins. The distance between the first short-circuit detection connection part 221h and the second short-circuit detection connection part 221h and other contact parts is far enough, and the stylus tips of other functions on the stylus holder 11 will not, like the prior art, easily cause the stylus tips of other functions to contact with the short-circuit detection contact part and cause a short circuit when passing through the short-circuit detection contact part by mistake during the installation of the consumable box 2.

[0161] In this embodiment, the structures of the consumable box 2 and the printing device 1 are consistent with those described in Embodiment 7 and will not be described again here.

[0162] Embodiment 9

[0163] like Figure 36 to Figure 39 As shown, another consumables box is provided in this embodiment. The difference between this embodiment and the eighth embodiment is that the structure of the connecting portion 22i in this embodiment is different.

[0164] In this embodiment, a bending portion is further provided on the contact portion on the short circuit detection connection portion. When the consumable box 2 is installed on the printing device 1, the contact portion abuts against the top of the contact pin on the contact pin through the bending portion to form an electrical connection.

[0165] Specifically, in this embodiment, the first short-circuit detection connection portion 221i is provided with a first embedded portion 2211i, a first contact portion 2212i and a second embedded portion 2213i at the end not connected to the substrate 210; the second short-circuit detection connection portion 222i is provided with a third embedded portion 2221i, a second contact portion 2222i and a fourth embedded portion 2223i at the end not connected to the substrate. The first contact portion 2212i and the second contact portion 2222i further include a first bending portion 2214i and a second bending portion 2224i, respectively. The first contact portion 2212i and the second contact portion 2222i first extend in the X-axis direction, and can first wrap the intersection of the upper end surface 111 of the stylus holder and the rear end surface of the stylus holder, and then bend in the negative direction of the Y-axis to form the first bending portion 2214i and the second bending portion 2224i, respectively. Therefore, when the consumable box 1 is installed on the printing device 1, the short-circuit detection connection portion is in rigid contact or elastic contact with the stylus top 11011 of the first stylus 1101 and the stylus top 11041 of the second stylus 1104 through the first bending portion 2214i and the second bending portion 2224i, respectively, to complete the electrical connection with the printing device 1.

[0166] The consumable chip of the utility model sets some terminals at a position away from other terminals to avoid short circuit caused by the contact pins of the printing device contacting terminals that do not correspond to their functions when the consumable box is installed; and the terminals away from other terminals contact the top of the contact pins of the printing device through the connecting part, so that the consumable chip can be stuck to the top of the contact pin holder to avoid the consumable chip from moving downward.

[0167] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all belong to the protection scope of the present invention.
