Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a consumable cartridge. Background Art

[0002] The consumable cartridge belongs to printing consumables. A chip is arranged on the outer wall of the consumable cartridge. The chip is used to record information about the consumable cartridge, such as model, ink or toner remaining amount, etc. The contact pins in the printing device are electrically connected to the chip for communication. In order to prevent some conductive foreign matters from adhering to the surface of the chip, causing a short circuit between the terminals on the chip, resulting in the chip being burned out or the printing device not recognizing the machine, some terminals on the chip are usually arranged on the back of the chip, and then a conductive member is added to realize the communication between the terminals on the back of the chip and the target contact pins of the printing device.

[0003] In some solutions, the conductive member extends from one side of the chip, and a pressing arm is arranged outside the chip installation position of the consumable cartridge. When the consumable cartridge is installed in the printing device, the pressing arm presses the side wall of the target contact pin facing the chip to deform, and contacts the conductive member arranged on the side wall of the chip. However, the magnitude of the force applied by the pressing arm is strictly required. If the force applied by the pressing arm on the target contact pin is too large, the target contact pin will directly cross to the upper surface of the chip, making the target contact pin unable to contact the conductive member arranged on the side wall of the chip. If the force applied by the pressing arm is too small, the target contact pin will not deform enough, and the target contact pin will also be unable to contact the conductive member arranged on the side wall of the chip, thereby causing the problem that the chip and the printing device cannot communicate normally.

[0004] Therefore, it is urgent to solve the technical problem of unstable communication between the chip and the printing device. Summary of the Utility Model

[0005] The utility model provides a consumable cartridge to solve the technical problem of unstable communication between the chip and the printing device.

[0006] To achieve the above object, the utility model provides a consumable cartridge detachably arranged in a printing device. The printing device includes a support frame movably arranged along a first direction and a contact pin assembly arranged on the support frame. The contact pin assembly includes a contact pin holder and a first contact pin. The consumable cartridge includes:

[0007] A body having an installation position and a force application part;

[0008] A chip having a first contact part. Along the first direction, a recessed part is formed between the inner wall of the chip facing the installation position and the inner wall of the installation position, and the first contact pin enters the recessed part;

[0009] A conductive member, at least part of the conductive member is disposed on the inner wall of the recess along the first direction, and the conductive member is in contact with the first contact portion to achieve electrical connection;

[0010] The force - applying portion is configured to apply a first acting force to the support frame along the first direction during the process of loading the consumable cartridge into the printing device, so that the first contact pin abuts against the inner wall surface of the recess. The inner wall of the recess applies a second acting force to the first contact pin, forcing the first contact pin to deform in a direction close to the conductive member and contact the conductive member. The direction of the second acting force is opposite to that of the first acting force.

[0011] A consumable cartridge provided by the present utility model forms a recess between the inner wall of the chip facing the installation position and the inner wall of the installation position along the first direction. When the consumable cartridge is loaded into the printing device, the first contact pin extends into the recess. When the force - applying portion presses the support frame of the printing device, since the inner wall of the recess limits the first contact pin in the first direction, even if the acting force applied by the force - applying portion to the support frame of the printing device is too large, it can be avoided that the first contact pin jumps out of the recess; even if the acting force applied by the force - applying portion to the contact - pin frame of the printing device is too small, under the squeezing force of the force - applying portion, the contact - pin frame can still drive the first contact pin to displace until it abuts against the inner wall of the recess. Under the reaction force of the inner wall of the recess on the first contact pin, it is ensured that the first contact pin deforms in a direction close to the conductive member and contacts the conductive member to achieve electrical connection. It effectively solves the problem in the prior art that the force - applying intensity of the extrusion arm on the first contact pin cannot be accurately controlled, resulting in the first contact pin being prone to cross to the side of the chip facing away from the body, affecting the stable contact between the chip and the conductive member, thereby improving the stability of the electrical connection between the chip and the printing device, ensuring the information interaction and the realization of related functions between the chip and the printing device, and reducing the failure rate during the use of the chip.

[0012] In a possible implementation manner, one side of the chip has a notch portion and a first side wall facing the notch portion along the first direction. The installation position has a second side wall, and the second side wall faces the first side wall. The first side wall and the second side wall are respectively configured as two opposite inner wall surfaces of the recess;

[0013] Along the second direction, the conductive member is blocked by the first side wall or the second side wall;

[0014] The conductive member is disposed on the first side wall, and along the first direction, at least part of the projection of the conductive member coincides with the first side wall; or,

[0015] The conductive member is disposed on the second side wall, and along the first direction, at least part of the projection of the conductive member coincides with the second side wall.

[0016] In a possible implementation manner, the body further has an aligned portion. Along the first direction, the aligned portion and the force-applying portion are respectively located on opposite sides of the installation position, both the aligned portion and the force-applying portion extend towards the installation position, and the extension length of the force-applying portion is greater than that of the aligned portion.

[0017] In a possible implementation manner, the conductive member includes a first portion located on the first side wall or the second side wall. The first portion has a first electrical contact portion for contacting the first contact pin.

[0018] In a possible implementation manner, the installation position includes a concave cavity and a plurality of stoppers provided on different side edges of the concave cavity. The plurality of stoppers include a first stopper. The second side wall is located on the side of the first stopper facing the concave cavity, and the first stopper further has a front surface facing the chip.

[0019] The conductive member further includes a second portion connected to the first portion. The first portion is located on the second side wall, and the second portion extends to the front surface of the first stopper. The second portion is provided with a second electrical contact portion, and the second electrical contact portion contacts the first contact portion to achieve electrical connection.

[0020] In a possible implementation manner, the body includes a first box body and a chip holder. The outer wall surface of the first box body has a placement portion, and the chip holder is detachably arranged in the placement portion. The surface of the chip holder facing away from the first box body is configured as the installation position.

[0021] In the first direction, the placement portion has a first inner wall and a second inner wall arranged opposite to each other. One of the force-applying portion and the aligned portion is arranged on the first inner wall, and the other of the force-applying portion and the aligned portion is arranged on the second inner wall.

[0022] In a possible implementation manner, the chip has a first surface facing the body, and the first contact portion is arranged on the first surface. In the second direction, the second portion coincides with the projection of at least part of the first contact portion.

[0023] In a possible implementation manner, the chip further includes a second contact portion. The chip further has a second surface facing away from the body. A hollow hole penetrating the first surface and the second surface is formed in the chip, and the second contact portion is arranged on the inner wall surface of the hollow hole for electrically connecting with a second contact pin among a plurality of contact pins.

[0024] In a possible implementation manner, the chip further includes a storage element, and at least one of the first contact portion and the second contact portion is electrically connected to the storage element.

[0025] In a possible implementation manner, the conductive member is disposed on the first sidewall. In the second direction, the distance between the conductive member and the second surface is greater than 0, and the conductive member is electrically connected to the storage element.

[0026] In a possible implementation manner, both sides of the support frame along the first direction are respectively provided with a first alignment portion and a second alignment portion. During the process of loading the consumable cartridge into the printing device, the first alignment portion and the second alignment portion respectively abut against the force application portion and the portion to be aligned.

[0027] For a consumable cartridge provided by the present utility model, by disposing the first contact portion on the side of the chip facing the body and disposing the second contact portion on the side of the chip facing away from the body, when a conductive foreign object falls on the side of the chip facing away from the body, the problem of chip short - circuit can be effectively prevented, ensuring the communication effect between the chip and the printing device.

[0028] For a consumable cartridge provided by the present utility model, the conductive member is located in the recessed portion. During the process of loading the consumable cartridge into the printing device, the first contact pin enters the recessed portion, and the first contact pin deforms to contact the conductive member to achieve electrical connection, improving the stability of the electrical connection between the first contact pin and the conductive member.

[0029] For a consumable cartridge provided by the present utility model, the conductive member is located in the recessed portion. During the process of loading the consumable cartridge into the printing device, the first contact pin enters the recessed portion, and the first contact pin deforms to contact the conductive member to achieve electrical connection, improving the stability of the electrical connection between the first contact pin and the conductive member. The first sidewall and the second sidewall have a limiting effect on the first contact pin in the first direction. Even if the force applied by the force application portion to the support frame is too large, it can avoid the first contact pin from striding to the upper surface of the chip. In addition, even if the force applied by the force application portion to the support frame is too small, since the support frame can still drive the first contact pin to displace and abut against the first sidewall under the extrusion force of the force application portion, under the action of the abutting force of the first sidewall on the first contact pin, the first contact pin can deform towards the second sidewall and contact the conductive member disposed on the second sidewall, effectively avoiding the problem in the prior art that due to the fact that the force application intensity of the extrusion arm cannot be accurately controlled, the target contact pin cannot contact the sidewall of the chip, improving the stability of the electrical connection between the chip and the printing device, ensuring the information interaction and the realization of related functions between the two, and reducing the failure rate during the use of the chip.

[0030] A consumable cartridge provided by the present utility model has a conductive member fixed relative to the chip or fixed relative to the body of the consumable cartridge, which solves the problem that due to the lack of constraints between the chip, the conductive member and the body of the consumable cartridge, when affected by external environments such as vibration and shaking, the installation postures of the chip and the conductive member are skewed or the conductive member falls off, etc., and ensures the communication effect between the chip and the printing device.

[0060] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0061] The consumable cartridge is a component that needs to be frequently replaced in a printing device. The printing device can be an inkjet printer, and the corresponding consumable cartridge is an ink cartridge storing ink. The printing device forms the text or pattern to be printed by spraying ink onto the paper; the printing device can also be a laser printer, and the corresponding consumable cartridges are a processing cartridge, a developing cartridge, a toner cartridge, etc. storing toner.

[0062] The consumable cartridge is provided with a chip, which is used to store information such as the manufacturer information, ink volume information, consumable cartridge category information, ink color, etc., relevant processing programs, and communication programs. In order to prevent some charged foreign objects such as ink droplets, metal wires, or metal debris from falling on the chip and causing a short circuit of the chip, some target terminals are arranged on the rear surface of the chip. The rear surface of the chip is the side of the chip facing the cartridge body, and the remaining terminals are arranged on the front surface of the chip. The front surface of the chip is the side of the chip facing away from the cartridge body, thereby reducing the occurrence of short circuits caused by charged foreign objects falling between the terminals on the chip.

[0063] In order to enable the target terminals located on the rear surface of the chip to be in contact with the corresponding target needles to achieve electrical connection, in some solutions, a conductive member is provided between the body of the consumable cartridge and the chip. The conductive member is electrically connected between the target terminals of the chip and the target needles of the printing device, thereby realizing the electrical connection between the target terminals and the target needles in the printing device and achieving the communication effect. During the assembly operation of the consumable cartridge, usually the chip, the conductive member, and the body of the consumable cartridge are pre-installed first. During installation, the chip is placed at the installation position of the body of the consumable cartridge, and the positioning protrusions provided on the body of the consumable cartridge are inserted into the positioning holes formed by the conductive member. Subsequently, the positioning protrusions extending out of the front surface of the chip are melted by a welding tooling to form a welded portion, and the welded portion abuts against the front surface of the chip to fix and install the chip and the conductive member.

[0064] However, during pre-installation, there is no effective mechanical constraint among the body of the consumable cartridge, the chip, and the conductive member. Affected by external environmental factors such as vibration and shaking, it is easy to cause the placement postures of the chip or the conductive member to be skewed. Furthermore, after the welding tooling melts the positioning protrusions, the installation postures of the chip or the conductive member form a certain angle with the consumable cartridge. If the offset angle of the installation posture of the chip or the conductive member is too large, it will affect the electrical contact effect between the chip and the conductive member and the electrical contact effect between the chip and the needles in the printing device, thereby affecting the communication stability between the chip and the printing device.

[0065] In addition, there may also be a hidden danger that the chip or the conductive member directly falls off the consumable cartridge. For example, if the operator fails to notice that the conductive member has fallen off the consumable cartridge and directly installs the chip, it will cause the terminals on the chip not to be electrically connected to the corresponding needles in the printing device, resulting in the inability to realize some functions of the chip and affecting the normal use of the chip.

[0066] In other solutions, a conductive member is integrally formed on the side wall of the chip, and a pressing arm is arranged outside the chip installation position of the consumable cartridge. When the consumable cartridge is loaded into the printing device, the target contact pin enters between the pressing arm and the chip. Under the action of an external force, the pressing arm presses the target contact pin to deform towards the side wall of the chip and contacts the conductive member arranged on the side wall of the chip. However, the force application intensity of the pressing arm cannot be precisely controlled. If the applied force is too large, the target contact pin will directly cross to the upper surface of the chip, resulting in the inability of the target contact pin to contact the conductive member arranged on the side wall of the chip. If the applied force is too small, the target contact pin will have too small a deformation degree, also resulting in the inability to contact the conductive member arranged on the side wall of the chip, thereby causing a problem that normal communication between the chip and the printing device cannot be achieved. In addition, since the pressing arm is arranged outside the chip installation position and lacks structural protection around it, during the transportation process of the consumable cartridge or during daily use, due to accidental collisions or high-altitude drops, etc., the pressing arm is easily damaged, causing the problem that the consumable cartridge cannot be used normally.

[0067] For better description of the consumable cartridge, refer to Figure 1 and Figure 2 as shown, a coordinate system is established:

[0068] In this example, the first direction is the direction indicated by the +X axis, and the first direction refers to the width direction of the chip; the second direction is the direction indicated by the +Y axis, the second direction refers to the thickness direction of the chip, and is also the installation direction of the consumable cartridge; the third direction is the direction indicated by the +Z axis, and the third direction refers to the height direction of the chip. The included angles between the first direction, the second direction, and the third direction can be 90°. In other possible implementation manners, the included angle between the first direction and the second direction can be 80° - 100°, for example, it can be 80°, 85°, 90°, 95°, or 100°.

[0069] Embodiment 1

[0070] The present utility model provides a consumable cartridge, which is detachably arranged in a printing device. Referring to Figure 3 as shown, the printing device includes a support frame 60 movably arranged along the first direction and a contact pin assembly 50 arranged on the support frame 60. The contact pin assembly 50 includes a contact pin holder 51 and a first contact pin 52. The number of the first contact pins 52 can be one, two, or more. The contact pin assembly 50 further includes a second contact pin 53, and the number of the second contact pins 53 can be one, two, or more.

[0071] Referring to Figure 4 and Figure 5 as shown, the present utility model provides a consumable cartridge, including: a main body 10, a chip 20, and a conductive member 30. The main body 10 has an installation position 11 and a force application part 12; the chip 20 is arranged in the installation position 11. Referring to Figure 1 andFigure 7 As shown, the chip 20 has a first contact portion 21. Refer to Figure 1 , Figure 2 and Figure 3 As shown, along the first direction, a recess 13 is formed between the inner wall of the chip 20 facing the mounting position 11 and the inner wall of the mounting position 11, and the first contact pin 52 enters the recess 13. At least part of the conductive member 30 is disposed on the inner wall of the recess 13 along the first direction, and the conductive member 30 contacts the first contact portion 21 to achieve electrical connection.

[0072] The force-applying portion 12 is configured to apply a first acting force to the contact pin holder 51 along the first direction during the process of loading the consumable cartridge into the printing device, so that the first contact pin 52 abuts against the inner wall surface of the recess 13, and the inner wall surface of the recess 13 applies a second acting force to the first contact pin 52, forcing the first contact pin 52 to deform in a direction close to the conductive member 30 and contact the conductive member 30, wherein the direction of the second acting force is opposite to that of the first acting force.

[0073] For a consumable cartridge provided by the present utility model, a recess 13 is formed between one side edge of the chip 20 along the first direction and the inner wall of the mounting position 11. When the consumable cartridge is loaded into the printing device, the first contact pin 52 extends into the recess 13. When the force-applying portion 12 presses the support frame 60 of the printing device, due to the inner wall of the recess 13 limiting the first contact pin 52 in the first direction, even if the acting force applied by the force-applying portion 12 to the support frame 60 of the printing device is too large, it can be avoided that the first contact pin 52 jumps out of the recess 13; even if the acting force applied by the force-applying portion 12 to the contact pin holder 51 of the printing device is too small, under the squeezing force of the force-applying portion 12, the contact pin holder 51 can still drive the first contact pin 52 to displace until it abuts against the inner wall of the recess 13. Under the reaction force of the inner wall of the recess 13 on the first contact pin 52, it is ensured that the first contact pin 52 deforms in a direction close to the conductive member 30 and contacts the conductive member 30 to achieve electrical connection.

[0074] For a consumable cartridge provided by the present utility model, it effectively solves the problem in the prior art that the force application intensity of the extrusion arm on the first contact pin 52 cannot be accurately controlled, resulting in the first contact pin 52 being prone to cross to the side of the chip 20 opposite to the body 10, affecting the stable contact between the chip 20 and the conductive member 30, thereby improving the stability of the electrical connection between the chip 20 and the printing device, ensuring the information interaction and the realization of related functions between the chip 20 and the printing device, and reducing the failure rate during the use of the chip 20.

[0075] In a possible implementation manner, refer to Figure 4 and Figure 5As shown, the main body 10 includes a first cartridge 16 and a chip holder 14. The first cartridge 16 includes an ink storage chamber 162 and a connecting member 163. An ink storage cavity is formed inside the ink storage chamber 162. The connecting member 163 is connected to the ink storage chamber 162. The connecting member 163 has a first ink outlet 165 that communicates with the inside of the ink storage cavity. The main body 10 further includes a housing 17, and the first cartridge 16 is disposed inside the housing 17. In this example, an installation portion 161 is formed on the outer wall of the connecting member 163, and the installation portion 161 is a groove-like structure that is recessed into the connecting member 163.

[0076] Reference Figure 5 and Figure 9 As shown, in order to facilitate the installation and disassembly of the chip holder 14, the connecting member 163 is provided with a clamping portion 1631, and a clamped portion 142 is provided on one side of the chip holder 14 facing the connecting member 163. The clamping portion 1631 and the clamped portion 142 are connected to each other to achieve the detachable connection between the chip holder 14 and the connecting member 163.

[0077] In a possible implementation manner, one of the clamped portion 142 and the clamping portion 1631 is a clamping protrusion, and the other is a clamping groove. The clamping protrusion extends into the clamping groove and is engaged with each other to achieve the detachable connection between the chip holder 14 and the connecting member 163. For example, the clamped portion 142 is a clamping protrusion protruding from the chip holder 14, and the clamping portion 1631 is a clamping groove formed in the connecting member 163; or the clamped portion 142 is a clamping groove formed in the chip holder 14, and the clamping portion 1631 is a clamping protrusion protruding from the connecting member 163.

[0078] In a possible implementation manner, reference Figure 6 、 Figure 7 and Figure 8 As shown, one side of the chip 20 has a notch portion 22 and a first side wall 221 facing the notch portion 22 along a first direction. The installation position 11 has a second side wall 141. The second side wall 141 faces the first side wall 221. The first side wall 221 and the second side wall 141 are respectively configured as opposite inner wall surfaces of the recessed portion 13.

[0079] In a possible implementation manner, the installation position 11 is used to install the chip 20. The installation position 11 includes a concave cavity 113 and a plurality of stoppers 114 provided on different side edges of the concave cavity 113. One of the plurality of stoppers 114 is a first stopper 1142. The second side wall 141 is located on one side of the first stopper 1142 facing the concave cavity 113. The first stopper 1142 further has a front surface 1141 facing the chip 20. The stopper 114 abuts against the chip 20. The concave cavity 113 can be used to avoid the storage elements provided on the chip 20.

[0080] In a possible implementation manner, reference Figure 6As shown, the mounting position 11 further includes positioning posts 1143 provided on the stoppers 114. Positioning holes 27 are also formed on the edge of the chip 20. The number of the positioning holes 27 can be one or more. For example, positioning holes 27 are respectively formed on different side edges of the chip 20. The positions of the positioning posts 1143 correspond to the positions of the positioning holes 27 and the numbers are the same. The positioning posts 1143 are correspondingly inserted into the positioning holes 27 to realize the positioning when the chip 20 is mounted on the mounting position 11.

[0081] In a possible implementation manner, referring to Figure 5 and Figure 11 As shown, the main body 10 further has an aligned portion 15. Along the first direction, i.e., the X direction, the aligned portion 15 and the force application portion 12 are respectively located on opposite sides of the mounting position 11. The aligned portion 15 and the force application portion 12 both extend towards the mounting position 11, and the extending length of the force application portion 12 is greater than that of the aligned portion 15. Such a structure makes the extending length of the force application portion 12 along the first direction longer, which helps the force application portion 12 to contact the support frame 60 and squeeze and push the support frame 60, so that the support frame 60 drives the contact needle holder 51 to move away from the force application portion 12 along the first direction.

[0082] In a possible implementation manner, referring to Figure 6 As shown, the conductive member 30 is disposed on the second side wall 141. Along the first direction, the projection of the conductive member 30 coincides with the projection of at least a part of the second side wall 141.

[0083] In a possible implementation manner, the conductive member 30 includes a first part 31. The first part 31 is located on the first side wall 221 or the second side wall 141. The first part 31 has a first electrical contact portion 311, and the first electrical contact portion 311 is used to contact the first contact needle 52.

[0084] The first electrical contact portion 311 can be a conductive bump or a conductive block protruding from the surface of the first part 31, which enhances the contact effect between the first electrical contact portion 311 and the first contact needle 52.

[0085] In a possible implementation manner, the mounting position 11 includes a cavity 113 and a plurality of stoppers 114 provided on different side edges of the cavity 113. The plurality of stoppers 114 include a first stopper 1142. The second side wall 141 is located on one side of the first stopper 1142 facing the cavity 113. The first stopper 1142 further has a front surface 1141 facing the chip 20;

[0086] In a possible implementation, the conductive member 30 further includes a second portion 32 connected to the first portion 31. The first portion 31 is located on the second sidewall 141, and the second portion 32 extends to the front surface 1141 of the first stopper 1142. The second portion 32 is provided with a second electrical contact portion 321, and the second electrical contact portion 321 contacts the first contact portion 21 to achieve electrical connection.

[0087] In the second direction, the projection of the second portion 32 coincides with at least a part of the projection of the first contact portion 21.

[0088] In this example, since the first surface 25 of the chip 20 abuts against the front surface 1141 of the first stopper 1142, the first contact portion 21 is located on the first surface 25 of the chip 20, the second portion 32 extends to the front surface 1141 of the first stopper 1142, and the projection of the second portion 32 coincides with the projection of a part of the first contact portion 21 in the thickness direction of the chip, that is, the Y direction. Therefore, after the chip 20 is installed in the installation position 11, the second portion 32 contacts the first contact portion 21 to achieve electrical connection, so that the first contact pin 52 contacting the first portion 31 is electrically connected to the first contact portion 21.

[0089] In a possible implementation, the conductive member 30 is fixedly connected to the chip carrier 14. The conductive member 30 can be a conductive metal member. For example, the conductive member 30 can be integrally formed with the chip carrier 14 by in-mold injection to achieve fixed connection, and there is no need to assemble the conductive member 30 and the chip carrier 14 again, which improves the assembly efficiency of the consumable cartridge. Of course, the conductive member 30 can also be fixedly connected to the chip carrier 14 by pasting.

[0090] In a possible implementation, along the second direction, the conductive member 30 is blocked by the second sidewall 141. In this example, along the second direction, the first portion 31 of the conductive member 30 is blocked by the second sidewall 141, effectively protecting the conductive member 30. The first portion 31 is located on the second sidewall 141. When the chip 20 and the chip carrier 14 are in the installed state, the first portion 31 of the conductive member 30 is blocked by the front surface 1141 of the first stopper 1142, and the second portion 32 of the conductive member 30 is blocked by the second sidewall 141.

[0091] In a possible implementation, the conductive member 30 can also be an electroplated film. The conductive member 30 can be attached to the chip carrier 14 by electroplating. The electroplated film can be formed of metal conductors such as nickel plating, chromium plating, copper plating, silver plating, etc. Such a structure can avoid the problem of the conductive member 30 falling off.

[0092] In a possible implementation, the conductive member 30 includes but is not limited to conductive stickers, conductive paints, conductive metals, etc.

[0093] In a possible implementation, refer toFigure 9 and Figure 10 As shown in Figure 10 , the conductive member 30 further includes a third portion 33. The third portion 33 is connected to the first portion 31, and there is an included angle between the third portion 33 and the first portion 31. A through portion 143 is provided on the chip carrier 14. In the thickness direction of the chip 20, that is, the Y direction, the through portion 143 is configured to penetrate from the surface of the chip carrier 14 facing the connecting member 163 to the surface of the chip carrier 14 facing away from the connecting member 163. The through portion 143 faces the second side wall 141. The chip carrier 14 further has a first accommodating portion 144 and a second accommodating portion 145. The first accommodating portion 144 is located on the front surface 1141 of the chip carrier 14, and the second accommodating portion 145 is located on the surface of the chip carrier 14 facing the connecting member 163. The first portion 31 of the conductive member 30 is located in the through portion 143, the second portion 32 of the conductive member 30 is located in the first accommodating portion 144, and the third portion 33 of the conductive member 30 is located in the second accommodating portion 145.

[0094] In a possible implementation manner, an installation portion 161 is provided on the outer wall surface of the first box body 16. The chip carrier 14 is detachably disposed in the installation portion 161, and the surface of the chip carrier 14 facing away from the first box body 16 is configured as an installation position 11.

[0095] In the first direction, the installation portion 161 has a first inner wall 111 and a second inner wall 112 disposed opposite to each other. One of the force applying portion 12 and the aligned portion 15 is disposed on the first inner wall 111, and the other of the force applying portion 12 and the aligned portion 15 is disposed on the second inner wall 112.

[0096] In this embodiment, the force applying portion 12 is disposed on the first inner wall 111, and the aligned portion 15 is disposed on the second inner wall 112, so that the force applying portion 12 and the aligned portion 15 face each other.

[0097] The force applying portion 12 protrudes from the first inner wall 111 along the -X direction, and the aligned portion 15 protrudes from the second inner wall 112 along the +X direction. Since the force applying portion 12 is disposed on the first inner wall 111, it can prevent the problem that the force applying portion 12 is easily damaged by impact under the shielding and protection of the first inner wall 111, ensuring the service life of the consumable cartridge and ensuring the normal use of the consumable cartridge.

[0098] In a possible implementation manner, referring to Figure 3 , Figure 7 and Figure 8 As shown, the chip 20 includes a first contact portion 21. The chip 20 has a first surface 25 facing the body 10, and the first contact portion 21 is disposed on the first surface 25.

[0099] In a possible implementation manner, the chip 20 further includes a second contact portion 24. The chip 20 further has a second surface 26 facing away from the body 10. A hollow hole 23 penetrating through the first surface 25 and the second surface 26 is formed in the chip 20. The second contact portion 24 is disposed on the inner wall surface of the hollow hole 23, and the second contact portion 24 is used for electrically connecting with a second contact pin 53 among a plurality of contact pins.

[0100] In a possible implementation manner, the hollow hole 23 can be a rectangular hole, a waist-shaped hole, a parallelogram hole, a trapezoidal hole, etc. The hollow hole 23 is a through hole penetrating through the first surface 25 and the second surface 26 of the chip 20. The second contact portion 24 can be integrally formed on the inner wall surface of the hollow hole 23.

[0101] In some examples, when the chip 20 includes a ground terminal, a power supply terminal, a reset terminal, a clock terminal, and a data terminal, the first contact portion 21 can be one or more of the ground terminal, the power supply terminal, the reset terminal, the clock terminal, and the data terminal. The second contact portion 24 includes the remaining contact portions except the first contact portion 21.

[0102] It should be noted that the ground terminal is used to receive a ground potential; the power supply terminal is used to receive a power supply potential different from the ground potential (such as 3.6V or 3.3V), and through this terminal, power is provided for the operation of the storage element; the reset terminal is used to reset the internal data of the storage element; the clock terminal is used to receive a clock signal; the data terminal is used for sending or receiving data signals, 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 supply terminal.

[0103] In a possible implementation manner, the chip 20 further includes a storage element (not shown in the figure), and at least one of the first contact portion 21 and the second contact portion 24 is electrically connected to the storage element.

[0104] After the consumable cartridge is loaded into the printing device, since the second contact portion 24 is disposed on the inner wall surface of the hollow hole 23, the second contact pin 53 can extend into the hollow hole 23 and contact the second contact portion 24 to achieve electrical connection. The first contact pin 52 can smoothly enter the recessed portion 13, and the first contact pin 52 contacts the conductive member 30 to achieve electrical connection. Compared with the structure in which the second contact portion 24 is disposed on the second surface 26 of the main body 10, when the second contact portion 24 contacts and electrically connects with the second contact pin 53, it can prevent the contact pin assembly 50 from displacing in a direction away from the chip 20 due to the acting force of the chip 20, thereby affecting the contact stability between the first contact pin 52 and the conductive member 30 and ensuring the normal realization of the function of the chip 20. In addition, in the present application, by disposing the second contact portion 24 on the inner wall surface of the hollow hole 23 and extending the second contact pin 53 into the hollow hole 23, the extrusion amount of the chip 20 on the second contact pin 53 can be reduced, and the problem of easy wear of the second contact pin 53 during long-term use can be solved, thereby ensuring the communication effect.

[0105] In a possible implementation manner, referring to Figure 3 as shown, both sides of the support frame 60 along the first direction respectively have a first alignment portion 61 and a second alignment portion 62. Referring to Figure 12 as shown, during the process of loading the consumable cartridge into the printing device, the first alignment portion 61 and the second alignment portion 62 respectively abut against the force application portion 12 and the portion to be aligned 15.

[0106] Referring to Figure 2 、 Figure 3 and Figure 6 as shown, during the process of loading the consumable cartridge into the printing device, the consumable cartridge moves along the third direction, i.e., the Z-axis direction. The first alignment portion 61 of the support frame 60 contacts the force application portion 12, and the second alignment portion 62 of the support frame 60 contacts the portion to be aligned 15. At this time, a part of the second contact pin 53 enters the hollow hole 23 and contacts the second contact portion 24 disposed on the inner wall surface of the hollow hole 23. The first contact pin 52 enters the recessed portion 13. The force application portion 12 applies a first acting force to the first alignment portion 61 along the first direction, forcing the support frame 60 to drive the contact pin assembly 50 to displace along the first direction, so that the first contact pin 52 contacts and abuts against the first side wall 221. The first side wall 221 applies a second acting force in the direction opposite to the first acting force to the first contact pin 52, forcing the first contact pin 52 to deform in a direction close to the second side wall 141 and contact the first electrical contact portion 311 of the conductive member 30 disposed on the second side wall 141, which helps to improve the stability of the electrical connection of the conductive member 30 and ensure the communication quality between the chip 20 and the printing device.

In the second direction, the distance between the conductive member 30 and the second surface 26 is greater than 0, and the conductive member 30 is electrically connected to the storage element.

[0109] Referring to Figure 16 As shown in Figure 16 , along the second direction, i.e., the thickness direction of the chip 20, the first sidewall 221 of the chip 20 includes a first front half wall 221a close to the second surface 26 and a first rear half wall 221b close to the first surface 25. The conductive member 30 is integrally formed on the first rear half wall 221b and is electrically connected to the storage element.

[0110] In the second direction, the conductive member 30 is shielded by the second surface 26 of the chip 20. The conductive member 30 includes a first portion 31 and does not include a second portion 32. The first portion 31 is provided with a first electrical contact portion 311.

[0111] In the second embodiment, the conductive member 30 includes a first portion 31. The first portion 31 is located on the first sidewall 221 or the second sidewall 141. The first portion 31 has a first electrical contact portion 311, and the first electrical contact portion 311 is used to contact the first contact pin 52. It should be noted that in this embodiment, referring to Figure 17 As shown in Figure 17 , the first contact portion 21 of the chip 20 is located on the first sidewall 221 of the chip 20, and the first contact portion 21 of the chip 20 is configured as the first electrical contact portion 311 of the first portion 31 of the conductive member 30.

[0112] In a possible implementation manner, referring to Figure 18 As shown in Figure 18 , when the first electrical contact portion 311 of the conductive member 30 is located on the first sidewall 221, the first electrical contact portion 311 can be an integral structure integrally connected to the first contact portion 21 located on the first surface 25 of the chip 20, and the conductive member 30 is electrically connected to the storage element through the first contact portion 21.

The force applying portion 12 is disposed on the first inner wall 111, and the portion to be aligned 15 is disposed on the second inner wall 112, such that the force applying portion 12 and the portion to be aligned 15 face each other.

[0114] Referring to Figure 13 , Figure 14 , Figure 15 and Figure 16As shown, during the process of loading the consumable cartridge into the printing device, the consumable cartridge is loaded into the printing device along the third direction. The second alignment portion 62 of the support frame 60 contacts the force application portion 12, and the first alignment portion 61 of the support frame 60 contacts the portion to be aligned 15. A part of the second contact pin 53 enters the hollow hole 23 and contacts the second contact portion 24 provided on the inner wall surface of the hollow hole 23. The first contact pin 52 enters the recessed portion 13. The force application portion 12 applies a first acting force to the second alignment portion 62 in the direction opposite to the first direction (-X direction), forcing the support frame 60 to drive the contact pin assembly 50 to displace in the direction opposite to the first direction (-X direction), so that the first contact pin 52 contacts and abuts against the second side wall 141. The second side wall 141 applies a second acting force in the direction opposite to the first acting force to the first contact pin 52, forcing the first contact pin 52 to deform in the direction towards the first side wall 221 and contact the first electrical contact portion 311 of the conductive member 30 provided on the first side wall 221, which helps to improve the stability of the electrical connection of the conductive member 30 and ensure the communication quality between the chip 20 and the printing device.

For example, the first contact portion 21 is arranged on the surface of the chip 20 facing the body 10 or on the first side wall 221 of the chip 20, and the second contact portion 24 is arranged on the surface of the chip 20 facing away from the body 10. When a conductive foreign object falls on the surface of the chip 20 facing away from the body 10, the problem of short circuit of the chip 20 can be effectively prevented, ensuring the communication effect between the chip 20 and the printing device.

[0116] Embodiment III

[0117] The difference between this Embodiment III and Embodiment I and Embodiment II is that:

[0118] Reference Figure 19 、 Figure 20 and Figure 21 As shown, the body 10 includes a second cartridge body 18. In this Embodiment III, there is no need to install a chip holder separately. Instead, one surface of the second cartridge body 18 along the second direction, i.e., the Y-axis, is configured as an installation position 11, and the chip 20 is arranged at the installation position 11.

[0119] Along the first direction, a recessed portion 13 is formed between the inner wall of the chip 20 facing the installation position 11 and the inner wall of the installation position 11. The recessed portion 13 is a gap between one side of the chip 20 and the inner wall of the installation position 11, and the first contact pin 52 enters the recessed portion 13. At least part of the conductive member 30 is arranged on the inner wall of the recessed portion 13 along the first direction, and the conductive member 30 contacts the first contact portion 21 to achieve electrical connection.

[0120] The installation position 11 includes a concave cavity 113 and a plurality of stoppers 114 disposed on different side edges of the concave cavity 113. The plurality of stoppers 114 includes a first stopper 1142. The second side wall 141 is located on a side of the first stopper 1142 facing the concave cavity 113. The first stopper 1142 also has a front surface 1141 facing the chip 20.

[0121] In a possible implementation manner, the first stopper 1142 is further provided with a first accommodation portion 144. The first accommodation portion 144 is located on the front surface 1141 and is used for accommodating the second portion 32 of the conductive member 30.

[0122] The inside of the second cartridge 18 is used for storing printing media. One end of the second cartridge 18 along the third direction has a second ink outlet 181 for the printing media stored inside the second cartridge 18 to flow out.

[0123] It should be noted that the printing media can be one of ink, toner, 3D printing media, etc.

[0124] The structure of the chip 20 in this embodiment is the same as that of the chip 20 in Embodiment 1 and Embodiment 2. The structure of the conductive member 30 in this embodiment is the same as that of the conductive member 30 in Embodiment 1 and Embodiment 2. Details are not described herein again.

[0125] In the third embodiment, the force application portion 12 and the alignment portion 15 may not be provided on the second cartridge 18 anymore, but are provided inside the installation unit of the printing device for installing the second cartridge 18. The process of applying force to the support frame 60 by the force application portion 12 and the alignment portion 15 is the same as that in Embodiment 1 and Embodiment 2, and details are not described herein again.

[0126] An ink cartridge provided by the present utility model, the conductive member 30 is located in the recessed portion 13. During the process of loading the ink cartridge into the printing device, the first contact pin 52 enters the recessed portion 13. Under the action of an external force, the first contact pin 52 deforms and contacts the conductive member 30 to achieve electrical connection, improving the stability of the electrical connection between the first contact pin 52 and the conductive member 30. The first side wall 221 and the second side wall 141 have a limiting effect on the first contact pin 52 in the first direction. Even if the force applied by the force application portion 12 to the support frame 60 is too large, it can avoid the first contact pin 52 from striding onto the upper surface of the chip 20. In addition, even if the force applied by the force application portion 12 to the support frame 60 is too small, since the support frame 60 can still drive the first contact pin 52 to displace and abut against the first side wall 221 or the second side wall 141 under the extrusion force of the force application portion 12, under the action of the abutting force of the first side wall 221 or the second side wall 141, the first contact pin 52 can deform towards the second side wall 141 or the first side wall 221 and contact the conductive member 30 provided on the second side wall 141 or the first side wall 221, effectively avoiding the problem in the prior art that due to the inability to accurately control the application strength of the extrusion arm, the target contact pin cannot contact the side wall of the chip 20, improving the stability of the electrical connection between the chip 20 and the printing device, ensuring the information interaction and the realization of related functions between the two, and reducing the failure rate during the use of the chip 20.

[0127] An ink cartridge provided by the present utility model, the conductive member 30 is fixed relative to the chip 20, or the conductive member 30 is fixed relative to the body 10 of the ink cartridge, solving the problem that due to the lack of restraint between the chip 20, the conductive member 30 and the body 10 of the ink cartridge, under the influence of external environments such as vibration and shaking, the installation postures of the chip 20 and the conductive member 30 are skewed or the conductive member 30 falls off, etc., ensuring the communication effect between the chip 20 and the printing device.
