Description

[0001] This application is a divisional application of the Chinese patent application with application number 202421213289.0, application date May 29, 2024, and patent name “A consumable box”. Technical Field

[0002] The utility model relates to the technical field of printers, in particular to a consumables box. Background Art

[0003] Imaging devices typically include replaceable consumable cartridges, such as ink cartridges. These cartridges are equipped with a chip that communicates with the printer's stylus pins. The chip has multiple terminals. If conductive foreign matter becomes lodged between the terminals during use, this can cause a short circuit, potentially burning the chip or causing the printer to fail to recognize the device. To address this issue, a connector is added to the ink cartridge. A first end of the connector is electrically connected to one of the chip's terminals, and a second end is electrically connected to at least a portion of the printer's stylus pins or to other conductive components in the printer (such as a main control circuit board).

[0004] However, the contact stability between the existing consumable box and the connector is poor. During use, the consumable box may be shaken by external environmental factors such as vibration and shaking, which may cause the second end of the connector to lose contact or become misaligned with the top of the target contact pin, thereby causing the connector and the target contact pin to be unable to have a stable electrical connection, affecting the communication quality between the consumable box and the printing device.

[0005] Therefore, there is an urgent need to improve the stability of the connection between the consumable box and the connector. Utility Model Content

[0010] The utility model provides a consumable box, in which, in the second direction, the side surface of the second end of the first contact pin has a side portion, and the side portion is exposed from the contact pin groove so that the end of the connecting piece can contact the side portion of the first contact pin, which can increase the contact area between the end of the connecting piece and the first contact pin, thereby improving the stability of the connection between the connecting piece and the first contact pin. When the consumable box encounters external environmental factors such as vibration and shaking during use, the problem of separation or misalignment between the connecting piece and the first contact pin is reduced, thereby improving the communication quality between the consumable box and the printing device. In addition, since the blocking portion blocks between two adjacent contact pin grooves, the top of some of the blocking portions has a notch, and the notch effectively increases the exposed area of ​​the side portion, which is beneficial to improving the stability of the connection between the connecting piece and the first contact pin, and improving the communication quality between the consumable box and the printing device.

[0011] In a possible implementation, there are two connectors, both of which are disposed between the box body and the chip, and the two connectors are in contact with each other to achieve electrical connection or integral connection.

[0016] When the consumable material box is in an installed state with the image forming apparatus, the overhanging portion contacts the side surface portion and abuts against the blocking portion.

[0017] In one possible implementation, the outer wall of the box body is provided with at least one fixing portion, the fixing portion is spaced apart from the placement portion, the fixing portion has an open cavity therein, and the first end of the connecting member has an arm portion;

[0023] The chip further includes a storage element, and at least one of the first terminals is electrically connected to the storage element;

[0024] An external contact portion is provided on the extending portion, and an electric contact portion is provided on the side portion of the first contact pin. The external contact portion is used to abut against the electric contact portion. Along the second direction, the projection of the extending portion partially overlaps with the projection of the side portion of the first contact pin.

[0025] In one possible implementation, the chip further includes a second terminal group, the second terminal group is located on a side of the chip facing away from the box body, and the second terminal group includes at least one second terminal;

[0027] The present application provides a consumables box, which can constrain the range of movement of the protruding part by abutting a part of the protruding part against the stylus slot, or inserting a part of the protruding part into the stylus slot, thereby effectively avoiding the problem in the prior art that the second end of the connector is a free end and lacks constraint, and the second end of the connector is easily misaligned with the top of the target stylus when encountering external environmental factors such as vibration and shaking, thereby avoiding the situation that the chip is burned or the printing device does not recognize the machine, or even the chip is short-circuited, and can greatly improve the safety of chip use.

[0028] The consumables box provided in the present application increases the contact area between the extending portion and the first contact pin by partially contacting the side surface of the first contact pin, thereby improving the stability of the electrical connection between the extending portion and the first contact pin, thereby improving the communication quality.

[0088] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0089] A consumables box is a component in a printing device that needs to be replaced frequently. The printing device can be an inkjet printer, and the corresponding consumables box is an ink cartridge that stores ink; the printing device can also be a laser printer, and the corresponding consumables box is a processing box, developer box, powder box, etc. that stores toner.

[0090] The chip installed on the body of the consumables box is used to store information such as the manufacturer, ink volume, consumables box category, ink color, related processing procedures, and communication programs. To prevent charged foreign objects from falling on the chip and causing a short circuit, some terminals are located on the rear surface of the chip, while the remaining terminals are located on the front surface of the chip, thereby reducing the problem of charged foreign objects falling on the chip and causing a short circuit. In order to enable the terminals located on the rear surface of the chip to contact the corresponding target contact pins, in some embodiments, a connector is provided on the body of the consumables box. The first end of the connector is electrically connected to the chip, and the second end of the connector is used to electrically connect to the target contact pin of the printing device, thereby achieving an electrical connection between the terminals on the rear surface of the chip and the target contact pin of the printing device, thereby achieving a communication effect.

[0091] In the existing consumables box, the second end of the connector extends too far beyond the outer wall of the consumables box and contacts the top of the target contact pin in a point-to-point manner, so the contact area is small. Since the top of the target contact pin is non-planar, the consumables box may be affected by external environmental factors such as vibration and shaking during use, which may cause the second end of the connector to lose contact with the top of the target contact pin, thereby causing the connector and the target contact pin to be unable to have a stable electrical connection, thereby reducing the communication quality between the consumables box and the printing device.

[0092] In addition, in the height direction of the consumable box, the second end of the connector is usually higher than the top of the target contact pin, and the second end of the connector is a free end. Therefore, during the operation of the consumable box, due to external environmental factors such as vibration and shaking, the second end of the connector is prone to contact and misalignment with the top of the target contact pin. For example, the first end of the connector is electrically connected to one of the terminals of the chip. If the terminal is a ground terminal or a power terminal, and the contact pin that the second end of the connector mistakenly contacts is a power contact pin or a ground contact pin, there is a hidden danger of the chip being burned after the printing equipment is powered on.

[0093] In the present application, along the second direction, the projection of the overhanging portion at the second end of the connector partially overlaps with the projection of the stylus, and the placement portion is configured to correspond to the position of the blocking portion along the third direction, so that a portion of the overhanging portion abuts against the side surface of the stylus. That is, the overhanging portion and the stylus are in surface-to-surface contact, and the contact surface is a plane. This can increase the contact area between the overhanging portion and the stylus, improve the stability of the electrical connection between the two, and enhance communication quality. Therefore, by improving the structure of the consumables box, the present application improves the contact method and contact position between the second end of the connector and the top of the stylus in the prior art, thereby resolving the problem of poor contact or loss of contact between the second end of the connector and the top of the stylus caused by external environmental factors such as vibration and shaking during use of the consumables box.

[0094] In addition, the present application can constrain the range of movement of the protruding part by abutting a part of the protruding part against the stylus slot, or inserting a part of the protruding part into the stylus slot, thereby effectively avoiding the problem in the prior art that the second end of the connector is a free end and lacks constraint, and when encountering external environmental factors such as vibration and shaking, the second end of the connector is easily misaligned with the top of the target stylus, thereby avoiding the situation that the chip is burned or the printing device does not recognize the terminal short-circuit, and can greatly improve the safety of chip use.

[0095] For a better description of the consumable cartridge components, refer to Figure 1 and Figure 3 As shown, a coordinate system is established: the width direction of the consumable box is the X-axis direction, the length direction of the consumable box is the Y-axis direction, and the height direction of the consumable box is the Z-axis direction, wherein the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0096] In this example, the first direction is the Z-axis, which is the height of the consumables box and the stylus holder. The second direction is the X-axis, which is the width of the consumables box. The third direction is the Y-axis, which is the length of the consumables box. The angles between the second, third, and first directions can be 90°.

[0097] refer to Figure 1 and Figure 2 As shown, the present invention provides a consumables cartridge that is detachably mounted on a mounting unit 50 of an image forming apparatus. The mounting unit 50 can carry one or more consumables cartridges. The mounting unit 50 has one or more receiving locations 51 therein for receiving consumables cartridges. For example, the mounting unit 50 has four receiving locations 51, allowing the mounting unit 50 to carry four consumables cartridges. The four consumables cartridges can store four different colors of ink or toner, such as black, yellow, blue, and red.

[0098] The mounting unit 50 is provided with a stylus assembly 40, which can be provided on the inner wall surface of the accommodation position 51. The stylus assembly 40 includes a stylus holder 41 and a first stylus group. Figure 3 and Figure 4 As shown, the stylus holder 41 includes a stylus slot 411 and a blocking portion 412 . The blocking portion 412 blocks between two adjacent stylus slots 411 . The first stylus group includes at least one first stylus 421 . The first stylus 421 is located in the stylus slot 411 .

[0099] refer to Figure 4 and Figure 5 As shown, the first contact pin 421 includes a first end and a second end. In a first direction, that is, in the height direction of the contact pin holder 41, the second end of the first contact pin 421 is higher than the first end of the first contact pin 421. That is, in the first direction, the second end of the first contact pin 421 is higher than the first end of the first contact pin 421.

[0100] In the second direction, the side surface of the second end of the first contact pin 421 has a side surface portion 422 , and the side surface portion 422 is exposed from the contact pin groove 411 ; the second direction and the first direction have an included angle.

[0101] In this example, the angle between the second direction and the first direction may be 89°, 90°, or 91°, etc.

[0102] refer to Figure 8 、 Figure 9 and Figure 10As shown, the consumables box includes a box body 10, a chip 20 and at least one connector 30, and the chip 20 and the connector 30 are both arranged in the box body 10. The chip 20 includes a first terminal group, and the first terminal group includes at least one first terminal 22. The connector 30 includes a first end and a second end. A portion of the first end of the connector 30 is used to electrically connect to the first terminal 22, and a portion of the second end of the connector 30 is used to electrically connect to the side portion 422. The electrical connection between the first terminal group of the chip 20 and the first contact pin 421 is achieved through the connector 30.

[0103] In one possible implementation, the first end of the connector 30 and the first terminal 22 may be electrically connected through electrical contact, and the second end of the connector 30 and the side surface 422 of the first contact pin 421 may be electrically connected through electrical contact.

[0104] In a possible implementation, the first terminal group is located on a side of the chip 20 facing the box body 10 , or the first terminal group is located on a side of the chip 20 facing away from the box body 10 .

[0105] In one possible implementation, reference Figure 4 and Figure 5 As shown, the blocking portion 412 blocks between two adjacent contact pin grooves 411, and the blocking portion 412 is used to block the first contact pin 421. Part of the contact pin groove 411 faces one end of the consumable box to form an outward-expanding groove 4121, and part of the side surface of the first contact pin 421 extending into the outward-expanding groove 4121 constitutes a side surface portion 422; when the consumable box and the image forming device are in an installed state, the second end of the connecting member 30 extends into the outward-expanding groove 4121 and abuts against the side surface portion 422.

[0106] In one possible implementation, in order to form the outward-expanding groove 4121, the blocking portion 412 includes a first blocking portion and a second blocking portion. The side of the first blocking portion facing the consumable box is an inclined surface, and the inclined surface is inclined toward the inside of the contact pin groove 411, so that an outward-expanding groove 4121 is formed between the inclined surfaces of two adjacent first blocking portions. The cross-section of the outward-expanding groove 4121 can be triangular or trapezoidal. The existence of the outward-expanding groove 4121 exposes part of the side surface of the first contact pin 421 extending into the outward-expanding groove 4121 and is no longer blocked by the side surface of the blocking portion 412, so that part of the side surface of the first contact pin 421 forms a side surface portion 422; the side of the second blocking portion facing the consumable box is a vertical surface, for example, the second blocking portion is cubic.

[0107] Of course, it can also be along the third direction, that is, the direction indicated by the Y-axis, the length of the first blocking portion is shorter than the length of the second blocking portion, and the first blocking portion and the second blocking portion are flush with the side facing away from the box body 10, so that the contact pin groove 411 is oriented toward one end of the consumable box to form an outward expansion groove 4121.

[0108] refer to Figure 4 and Figure 5 As shown, the stylus holder 41 further includes a bottom panel 413 connected to each barrier portion 412 , and each barrier portion 412 is connected through the connection function of the bottom panel 413 .

[0109] In one possible implementation, reference Figure 9 and Figure 10 As shown, the outer wall of the box body 10 is provided with at least one placement portion 11, and the placement portion 11 is used to accommodate part of the connector 30. The number of the placement portions 11 is the same as the number of the connector 30.

[0110] refer to Figure 3 、 Figure 10 and Figure 12 As shown, along the third direction, the projection of the seating portion 11 at least partially overlaps with the projection of the outwardly expanding groove 4121; that is, the position of the seating portion 11 is opposite the position of the outwardly expanding groove 4121, allowing the second end of the connector 30 extending from the seating portion 11 to more conveniently and accurately contact the side surface 422 of the first contact pin 421, achieving a stable electrical connection. The third direction and the second direction form an angle; in this example, the angle is 90°.

[0111] The second end of the connecting member 30 has an extending portion 31 , a portion of the extending portion 31 is located in the seating portion 11 , and another portion of the extending portion 31 extends to the outside of the consumable box in a direction opposite to the third direction.

[0112] refer to Figure 3 and Figure 6 As shown, when the consumables box and the image forming apparatus are in the installed state, the extension portion 31 contacts the side portion 422 , the extension portion 31 abuts the blocking portion 412 , or the extension portion 31 extends into the stylus groove 411 and abuts the inner wall of the stylus groove 411 .

[0113] The protruding portion 31 contacts the side portion 422, thereby realizing the electrical connection effect between the connector 30 and the first contact pin 421. The protruding portion 31 abuts against the blocking portion 412 or the protruding portion 31 extends into the contact pin groove 411 and abuts against the inner wall of the contact pin groove 411, in order to improve the stability of the contact between the protruding portion 31 and the side portion 422. When the protruding portion 31 abuts against the blocking portion 412, the blocking portion 412 provides a supporting effect on the protruding portion 31. When the protruding portion 31 extends into the contact pin groove 411 and abuts against the inner wall of the contact pin groove 411, the inner wall of the contact pin groove 411 provides a supporting effect on the protruding portion 31, which helps to reduce the shaking of the protruding portion 31.

[0114] An external contact portion (not shown in the figure) is provided on the extension portion 31, and an electrical contact portion (not shown in the figure) is provided on the side portion 422 of the first contact pin 421. The external contact portion is used to abut against the electrical contact portion. Along the second direction, the projection of the extension portion 31 partially overlaps with the projection of the side portion 422 of the first contact pin 421.

[0115] Along the second direction, i.e., the direction indicated by the X-axis, the projection of the extension portion 31 overlaps with the projection of a portion of the side portion 422, and the placement portion 11 is configured to correspond to the position of the blocking portion 412 along the third direction, so that the external contact portion of the extension portion 31 abuts against the electrical contact portion of the side portion 422 of the first contact pin 421. The third direction is the direction indicated by the Y-axis.

[0116] The present invention provides a consumable box, in which the projection of the extension portion 31 partially overlaps with the projection of the side portion 422 of the first contact pin 421 along the second direction, and the placement portion 11 is configured to correspond to the position of the blocking portion 412 along the third direction, so that when the consumable box and the image forming device are in an installed state, part of the extension portion 31 abuts against the side portion 422 of the first contact pin 421, thereby achieving electrical contact and connection between a part of the extension portion 31 and the side portion 422, and at the same time, one end of the part of the extension portion 31 abuts against the side wall of the external expansion groove 4121, so that even if the consumable box encounters external environmental factors such as vibration and shaking during use, the problem of the second end of the connector 30 and the first contact pin 421 being detached or misaligned is reduced, thereby improving the safety of chip use.

[0117] In one possible implementation, the side wall of the outward-expanding groove 4121 has a slope. During the process of installing the consumable box on the mounting unit 50 of the image forming device, if the consumable box is slightly misaligned or offset in the second direction, the connecting member 30 touches the slope of the side wall of the above-mentioned outward-expanding groove 4121. Under the reaction force of the side wall of the outward-expanding groove 4121 on the connecting member 30, the connecting member 30 will be deformed in the second direction. Therefore, the consumable box has a tendency to move toward the first contact pin 421, that is, to reset, which plays a role in suppressing the displacement of the consumable box in the second direction.

[0118] refer to Figure 7 As shown, when the consumables box is installed on the mounting unit 50 of the image forming device, since the side surface 422 of the first contact pin 421 is flat, the side surface 422 of the first contact pin 421 has a larger surface area along the second direction. Compared with the solution in the prior art in which the extension portion 31 abuts against the top of the first contact pin 421, the contact area between the extension portion 31 and the electrical contact portion provided on the side surface 422 of the first contact pin 421 can be increased, thereby improving the stability of the electrical connection between the extension portion 31 and the first contact pin 421 and improving the communication quality between the consumables box and the printing device.

[0119] In one possible implementation, reference Figure 9 and Figure 10 As shown, the box body 10 is provided with a mounting position 14. Along the first direction, that is, the Z-axis direction, the mounting position 14 is located at the lower side of the placement portion 11. The chip 20 is arranged on the mounting position 14. Figure 10 and Figure 11 As shown, the chip 20 includes a substrate 21 and a first terminal group. The first terminal group is arranged on a side of the substrate 21 facing the box body 10. The first terminal group includes at least one first terminal 22. The position of the first terminal 22 corresponds to the position of the first end of the connector 30.

[0120] In this application, the first contact pin 421 is a target contact pin, which is used to make corresponding contact with the first terminal 22 on the rear surface of the chip 20 through the second end of the connector 30, wherein a portion of the first end of the connector 30 is electrically connected to the second end of the connector 30.

[0121] refer to Figure 10 and Figure 11 As shown, the chip 20 is provided with a second terminal group on the side facing away from the box body 10 , and the second terminal group includes at least one second terminal 23 . The second terminal group is located on the side of the substrate 21 facing away from the box body 10 , and the second terminal group includes the second terminal 23 .

[0122] refer to Figure 7 and Figure 12 As shown, the contact pin assembly 40 also includes a second contact pin group, which is used to electrically connect to the second terminal 23. The second contact pin group includes at least one second contact pin 431, and the second contact pin 431 is located in the contact pin groove 411, wherein the second contact pin 431 is used to contact the second terminal 23 to achieve electrical connection, and the first contact pin 421 of the first contact pin group is used to achieve electrical connection with the first terminal 22 through the connector 30.

[0123] The second contact pin 431 includes a first end and a second end. In a first direction, i.e., the height direction of the contact pin holder 41, the second end of the second contact pin 431 is higher than the first end of the second contact pin 431. The first end of the second contact pin 431 is electrically connected to the second terminal 23. The electrical connection can be achieved by the first end of the second contact pin 431 contacting the second terminal 23.

[0124] refer to Figure 12 and Figure 13 As shown, the second contact pin 431 and the first contact pin 421 have the same structure. Both the second contact pin 431 and the first contact pin 421 include a supporting portion 4211 and a pin portion 4212. The pin portion 4212 is connected to both sides of the bottom end of the supporting portion 4211. In a first direction, the top end of the supporting portion 4211 is away from the pin portion 4212. In a second direction, the pin portion 4212 protrudes outward from the contact pin slot 411. The top end of the supporting portion 4211 is located in the contact pin slot. The supporting portion 4211 is constructed as an arc-shaped structure.

[0125] In a possible implementation, there are two connectors 30 , both of which are disposed between the box body 10 and the chip 20 , and the two connectors 30 are in contact with each other to achieve electrical connection or integral connection.

[0126] In the present application, the connector 30 is provided to establish an electrical connection between the first contact pin group of the image forming device and the chip 20 for transmitting data or current so that the chip 20 can communicate with the image forming device.

[0127] In one possible implementation, the two connectors 30 are in contact with each other, that is, the two connectors 30 are electrically connected by physical contact. The two connectors 30 can also be connected as one piece, so that both connectors 30 are used for installation detection. The connector 30 is electrically connected to the first contact pin 421, and a specific circuit in the printer is turned on to achieve the installation detection effect.

[0128] In one possible implementation, there are two connecting members 30 and two notches 4122. If the consumable box is slightly misaligned in the second direction, the connecting member 30 acts on the corresponding side portion 422, causing the connecting member 30 to elastically deform in the second direction. By cooperating with the side portions 422 corresponding to the first contact pins 421, the effect of suppressing the displacement of the consumable box in the second direction can also be improved.

[0129] refer to Figure 10 and Figure 11 As shown, the chip 20 further includes a storage element 24 . The storage element 24 is disposed on the substrate 21 , and at least one first terminal 22 is electrically connected to the storage element.

[0130] In this example, the storage element 24 can be disposed on the side of the substrate 21 facing the housing 10, with the first terminal 22 and the second terminal 23 both electrically connected to the storage element 24. The storage element 24 can store information about the chip 20, such as manufacturer information, ink volume information, consumable cartridge type information, ink color information, and related processing and communication programs. It should be noted that the storage element 24 can also be disposed on the side of the substrate 21 facing away from the housing 10.

[0131] In a possible implementation, when the number of the first terminals 22 is two or more, some or all of the two or more first terminals 22 may not be electrically connected to the storage element 24 .

[0132] In one possible implementation, reference Figure 6 and Figure 12As shown, a side surface portion 422 of the first contact pin 421, which is adjacent to the second end and is located in the second direction or in a direction opposite to the second direction, is exposed through the outwardly expanding groove 4121. Along the third direction, the projection of the seating portion 11 at least partially overlaps with the projection of the outwardly expanding groove 4121. The third direction is the direction from the consumables box toward the contact pin assembly 40, i.e., the longitudinal direction of the consumables box.

[0133] The purpose of such a structure is to ensure that when the consumable box is installed in the installation unit 50 of the image forming device, the external contact portion of the extending portion 31 located in the placement portion 11 can contact the electrical contact portion of the first contact pin 421, thereby preventing the second end of the connecting member 30 from being separated from or misaligned with the first contact pin 421, improving the stability of the electrical connection between the second end of the connecting member 30 and the first contact pin 421, and ensuring the communication quality between the consumable box and the printing device.

[0134] The side surface 422 of the second end of the first contact pin 421 is exposed from the outwardly expanded groove 4121, which increases the exposed area of ​​the side surface 422 of the first contact pin 421, helps to increase the contact area between the second end of the connector 30 and the first contact pin 421, thereby improving the stability of the electrical connection between the second end of the connector 30 and the first contact pin 421.

[0135] In one possible implementation, reference Figure 2 and Figure 9 As shown, the accommodating position 51 of the mounting unit 50 has an alignment portion 52, and the box body of the consumable box has an aligned portion 17. When the consumable box is loaded into the accommodating position 51 of the mounting unit 50, the aligned portion 17 engages with the alignment portion 52, which can limit the width direction of the consumable box, that is, the X-axis direction.

[0136] In one possible embodiment, the aligned portion 17 is an aligned surface, and the box body 10 has two aligned surfaces in the width direction of the consumable box; the alignment portion 52 is located on the inner wall of the accommodating position 51, and the alignment portion 52 is constructed as an alignment protrusion. A plurality of alignment protrusions are provided on the accommodating position 51 of the installation unit 50, and the two aligned surfaces are respectively engaged with the plurality of alignment protrusions.

[0137] The aligned portion 17 of the consumable box is engaged with the alignment portion 52 of the mounting position of the mounting unit 50, and enters the mounting position of the mounting unit 50 along the mounting direction of the consumable box. By limiting the width direction of the consumable box, the placement portion 11 and the outward expansion groove 4121 can be further aligned in the third direction, which is beneficial to improving the accuracy of the electrical connection between the outward extension portion 31 of the connector 30 and the electrical contact portion provided near the second end of the first contact pin 421, and avoiding the problem of the chip 20 being short-circuited and burned due to the misalignment of the contact between the second end of the connector 30 and the first contact pin 421.

[0138] In one possible implementation, reference Figure 3 、 Figure 6 and Figure 12 As shown, part of the extension portion 31 extends into the stylus groove 411. When the extension portion 31 contacts the first stylus 421, a portion of the extension portion 31 and the stylus groove 411 abut against the inner wall surface of the stylus groove 411, thereby improving the contact stability between the extension portion 31 and the first stylus 421.

[0139] In one possible implementation, the end of the extension portion 31 away from the housing 10 abuts against the inner wall of the outwardly expanding groove 4121. When the extension portion 31 contacts the first contact pin 421, a portion of the extension portion 31 abuts against the inner wall of the outwardly expanding groove 4121, thereby improving the stability of the contact between the extension portion 31 and the first contact pin 421.

[0140] In one possible implementation, reference Figure 9 and Figure 10 As shown, the outer wall of the box body 10 is provided with at least one fixing portion 12, and the fixing portion 12 and the placement portion 11 are spaced apart along the first direction. The first end of the connector 30 is provided on the fixing portion 12. The fixing portion 12 is used to limit the first end of the connector 30 to prevent the first end of the connector 30 from being displaced or falling out. When the chip 20 and the box body 10 are in the installed state, the inner contact portion provided on the arm portion 32 of the first end of the connector 30 is used to contact the first terminal 22 to achieve electrical connection.

[0141] The first end of the connector 30 and the chip 20 may be connected by welding, bonding, abutting or clamping, so as to improve the relative stability between the connector 30 and the chip 20 .

[0142] The fixing portion 12 is located at the installation position 14 of the box body 10 . The fixing portion 12 may be cylindrical and protrude from the inner wall of the installation position 14 .

[0143] In one possible implementation, reference Figure 10 and Figure 11 As shown, the fixing portion 12 has an opening 122 therein, and the first end of the connector 30 has an arm 32. When the chip 20 is mounted on the mounting position 14 of the box body 10, the opening 122 can avoid the storage element 24.

[0144] In one possible implementation, reference Figure 14 and Figure 15 As shown, the arm portion 32 is disposed in the open cavity 122 .

[0145] In another possible implementation, reference Figure 10 As shown, the arm portion 32 is disposed on the outer wall of the opening cavity 122 , thereby achieving fixation of the arm portion 32 .

[0146] In one possible implementation, reference Figure 15 and Figure 16 As shown, the fixing portion 12 also includes a notch 121 for the arm portion 32 to pass through. The notch 121 extends through the side wall of the opening cavity 122. The notch 121 is provided to facilitate the installation of the arm portion 32 into the opening cavity 122. The arm portion 32 and the opening cavity 122 are installed in an interference fit to prevent the wall portion from falling out of the opening cavity 122.

[0147] In one possible implementation, reference Figure 15 、 Figure 16 and Figure 19 As shown, the outer wall of the box body 10 is also provided with a guide groove 13, which is connected to the placement portion 11. The first end of the connecting member 30 also includes a connecting portion 33, which is connected between the extending portion 31 and the arm portion 32, and at least part of the connecting portion 33 is embedded in the guide groove 13.

[0148] The guide groove 13 is a structure recessed into the box body 10 . The guide groove 13 can guide the direction of the connecting portion 33 and improve the stability of the fixing of the connecting portion 33 .

[0149] Exemplarily, the connector 30 may be made of a conductive material, for example, at least one metal wire, such as a copper wire, formed by bending, which not only meets the conductivity requirement but also has sufficient elastic deformation capability.

[0150] In some examples, to ensure safety in use, the remaining portion of the connector 30 , except for the first end of the connector 30 and the second end of the connector 30 , may be provided with a coating or an insulating layer.

[0151] In one possible implementation, reference Figure 15 、 Figure 16 and Figure 19 As shown, at least two fixing portions 12 are arranged at intervals along the second direction, and one of the at least two fixing portions 12 is further provided with an avoidance groove 123 , which is connected between the guide groove 13 and the opening 122 .

[0152] In this example, refer to Figure 19 and Figure 20 As shown, the number of the first terminals 22 can be two, and the two first terminals 22 can be arranged at intervals along the second direction. In order to electrically connect the two first terminals 22 with the corresponding first contact pin groups, the number of the connectors 30 is two, and the two connectors 30 are each connected between the first terminal 22 and the corresponding first contact pin 421. Correspondingly, reference Figure 17 and Figure 18As shown, in each stylus holder 41 , the number of stylus slots 411 having outwardly expanded slots 4121 may be two, and the side surfaces 422 of the second ends of the two first stylus pins 421 are exposed along the second direction or the direction opposite to the second direction through the two outwardly expanded slots 4121 .

[0153] In one possible implementation, reference Figure 14 and Figure 15 As shown, part of the connecting portion 33 extends into the guide groove 13 through the avoidance groove 123. By providing the avoidance groove 123, the fixing of the connecting member 30 is made more convenient.

[0154] In a possible implementation, part of the connecting portion 33 extends into the guide groove 13 through the notch 121 .

[0155] In a possible implementation, along the third direction, a projection of the first terminal 22 at least partially overlaps with a projection of the first end of the connector 30 .

[0156] Of course, there may be more than one first terminal 22 , and the corresponding fixing portions 12 are arranged at intervals along the second direction.

[0157] In some examples, when the chip 20 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, and a data terminal, the first terminal 22 may be two or more of the ground terminal, the power terminal, the reset terminal, the clock terminal, and the data terminal. The second terminal group includes the remaining terminals other than the first terminal 22 in the first terminal group. It should be noted that the ground terminal is used to receive a ground potential; the power terminal is used to receive a power potential different from the ground potential (such as 3.6V or 3.3V), and this terminal provides power for the operation of the storage element 24; the reset terminal is used to reset the data within the storage element 24; the clock terminal is used to receive a clock signal; the data terminal is used to send or receive a data signal, and is also used to detect a short circuit between the data terminal and at least one of the clock terminal, the reset terminal, and the power terminal.

[0158] In other examples, when the chip 20 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, a data terminal, a high-voltage terminal, and a detection terminal, the first terminal 22 can be two or more of the ground terminal, the power terminal, the reset terminal, the clock terminal, the data terminal, the high-voltage terminal, and the detection terminal, and the second terminal group includes the remaining terminals other than the first terminal 22 in the first terminal group. It should be noted that the high-voltage terminal is used to detect whether the consumables box is correctly loaded into the image forming device. The detection terminal is used to detect whether a short circuit occurs between the high-voltage terminal of the chip and at least one of the remaining terminals (i.e., the low-voltage terminal).

[0159] In this example, refer to Figure 17As shown, ink is stored inside the box body 10, and an ink outlet nozzle 16 is provided at the bottom of the box body 10. The ink outlet nozzle 16 is used to allow the ink stored inside the box body 10 to flow out and supply ink to the image forming device. The outer wall of the box body 10 is also provided with a handle 15. When the consumable box is installed in the installation unit 50, the handle 15 is used to engage with a part of the installation unit 50 to prevent the consumable box from popping out of the installation unit 50.

[0160] When the chip 20 is installed in the box body 10, the arm 32 of the connector 30 is provided with an inner contact (not shown in the figure), and the first terminal 22 contacts the inner contact accordingly. When the consumable box and the installation unit 50 are in the installed state, the second terminal 23 of the chip 20 is electrically connected to the first end of the second contact pin 431, and the outer contact provided on the extending portion 31 of the connector 30 is electrically connected by abutting against the side portion 422 of the first contact pin 421. A part of the extending portion 31 abuts against the inner wall of the outer expansion groove 4121 to support the extending portion 31 of the connector 30, thereby avoiding the problem in the prior art that the extending portion 31 and the first contact pin 421 cannot be stably electrically connected or are out of contact due to the influence of external environment such as vibration and shaking.

[0161] In one possible implementation, reference Figure 4 and Figure 5 As shown, the top of the partial blocking portion 412 has a notch 4122, and the notch 4122 is located on the side of the blocking portion 412 facing the consumable box, and the side portion 422 is exposed in the second direction through the notch 4122; when the consumable box and the image forming device are in an installed state, the second end of the connecting member 30 extends into the notch 4122 and abuts against the side portion 422.

[0162] In one possible implementation, the notch 4122 is a cavity formed by a missing portion of the top of the barrier portion 412. For example, it can be a rectangular cavity. The structure is simple and easy to process.

[0163] In one possible implementation, the number of notches 4122 can be one, or two or more. The two or more notches 4122 can be spaced apart along the second direction. For example, the tops of two or more mutually spaced barrier portions 412 each have a notch 4122. This structure allows for greater flexibility in the number and position of the notches 4122. The notches 4122 can be distributed in different locations, exposing more side surfaces of the first contact pins 421 through the notches 4122 to accommodate different chip designs and connection requirements. This is particularly convenient and practical for chips 20 with a large number of terminals requiring electrical connection of multiple terminals, providing sufficient connection points to ensure that all terminals can be effectively connected.

[0164] The provision of the notch 4122 allows the end of the connector 30 to contact the side surface portion 422 , and the side surface portion 422 provides a surface for the end of the connector 30 to contact the first contact pin 421 .

[0165] This structure achieves electrical connection through physical contact by the end of the connector 30 abutting the side portion 422. Furthermore, during installation of the consumable cartridge in the mounting unit 50 of the image forming apparatus, if the consumable cartridge is slightly misaligned or offset in the second direction, the end of the connector 30 will elastically deform in the second direction. Consequently, the offset of the consumable cartridge in the second direction will be suppressed by the mating abutment between the connector 30 and the side portion 422, helping to ensure that the consumable cartridge is correctly installed in the second direction.

[0166] In this example, one, two, or more blocking portions 412 may have a notch 4122 at their top ends. The contact pin slots 411 on both sides of the blocking portion 412 are connected through the notch 4122. The notch 4122 exposes the side portions 422, preventing the blocking portion 412 from blocking the side portions 422. This allows the second end of the connector 30 to extend into the notch 4122 and abut against the side portions 422, thereby achieving electrical connection between the second end of the connector 30 and the first contact pin 42.

[0167] The notch 4122 is a gap at the top of the blocking portion 412 , such that the side surface portion 422 of the first contact pin 421 is exposed along the second direction or a direction opposite to the second direction.

[0168] refer to Figure 3 、 Figure 10 and Figure 12 As shown, along the third direction, the projection of the seating portion 11 at least partially overlaps with the projection of the notch 4122. Alternatively, the location of the seating portion 11 is opposite to the location of the notch 4122, so that the second end of the connector 30 extending from the seating portion 11 can more conveniently and accurately contact the side surface 422 of the first contact pin 421, achieving a stable electrical connection.

[0169] When the consumables cartridge is installed with the image forming apparatus, a portion of the extension portion 31 contacts the side portion 422. In this example, the external contact portion of the extension portion 31 contacts the electrical contact portion of the side portion 422, ensuring electrical connection.

[0170] In one possible implementation, there are two receiving portions 11, arranged side by side along the second direction on the outer wall of the box body 10. The two receiving portions 11 each accommodate two connectors 30. The two receiving portions 11 are located in two independent installation positions to facilitate accommodating the two connectors 30. This helps ensure that the two connectors 30 remain stable and correctly positioned during installation, achieving a reliable connection.

[0171] In one possible implementation, the placement portion 11 is a groove that is recessed from the outer wall of the box body 10 to the interior of the box body 10 to accommodate part of the connecting member 30. The placement portion 11 provides a certain support for the connecting member 30, reducing the movement or loosening of the connecting member 30 during use.

[0172] It should be noted that, in the present application, the chip 20 may not have the second terminal group, and all terminals of the chip 20 are constructed as the first terminal group, that is, all terminals of the chip 20 are located on the side of the chip 20 facing the box body 10 .

[0173] It should be noted here that the numerical values ​​and numerical ranges involved in this application are approximate values.
