Description

Technical Field

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

[0002] Image forming devices such as printers are common office equipment. The consumable cartridge installed inside is a component that needs to be frequently replaced. The inside of the consumable cartridge is filled with ink, and a chip is arranged on the surface. The chip is used for communicating and connecting with the contact pins of the image forming device to realize signal transmission. During the long-term use of the ink cartridge, some conductive foreign matters (ink droplets, metal wires, metal debris, etc.) may adhere to the surface of the ink cartridge. If the foreign matter adheres between the terminals on the outer surface of the chip, it will cause a short circuit of the chip, and then the chip will be burned out or the printer will not recognize the machine. To solve the above problems, in the prior art, an electrical connector is often added to the consumable cartridge, and some terminals of the chip are arranged on the back of the chip. The first end of the electrical connector is electrically connected to one of the terminals on the back of the chip, and the second end of the electrical connector is electrically connected to at least part of the target contact pins in the imaging device to realize signal transmission.

[0003] In the prior art, in the production operation, the chip, the electrical connector and the cartridge body of the consumable cartridge are usually pre-installed first. During the pre-installation, the positioning holes provided on the chip and the electrical connector pass through the positioning protrusions provided on the consumable cartridge. The chip and the electrical connector are placed on the cartridge body of the consumable cartridge, and then the positioning protrusions are melted by a welding tooling to form a welding part, which abuts against a part of the chip, so as to fix and install the chip and the electrical connector on the consumable cartridge.

[0004] However, during the process of melting the positioning protrusions by the welding tooling to form the welding part, the installation posture of the chip is likely to shift. If the shift angle is too large, the terminals arranged on the chip cannot be electrically connected or have poor contact with the contact pins in the printer, thereby causing an unstable communication problem between the chip and the printer and affecting the normal use of the chip.

[0080] 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 making creative efforts fall within the protection scope of the present utility model.

[0081] In the production operation of the consumable cartridge, usually the chip, the electrical connection member and the cartridge body of the consumable cartridge are pre - installed first, that is, the positioning holes provided on the chip and the electrical connection member pass through the positioning posts provided on the cartridge body, so as to realize the pre - installation of the chip and the electrical connection member with the placement portion of the cartridge body. Subsequently, the positioning posts provided on the cartridge body are melted by a welding tooling to form a welded portion, and the welded portion abuts against a part of the chip, so as to realize the fixed installation of the chip and the electrical connection member on the cartridge body of the consumable cartridge.

[0082] However, during the pre - installation process, since the positioning hole on the chip only contacts the positioning post on the consumable cartridge and no effective mechanical constraint is formed between the two, the chip is prone to move along the length direction of the consumable cartridge. The chip and the electrical connection member are in a free state. Also, because the first ends of the chip and the electrical connection member are in contact, the chip will be subjected to a force applied by the first end of the electrical connection member along the length direction of the consumable cartridge, causing the placement posture of the chip to be skewed. Furthermore, after the welding tooling melts the positioning post, the installation posture of the chip is skewed, that is, the chip is no longer parallel to the outer wall surface of the cartridge body. If the skew angle is too large, it is likely to cause poor contact of the contact portion provided on the chip or even inability to electrically connect with the probe in the printer, and further lead to an unstable communication connection between the chip and the printer.

[0083] In addition, during the pre-installation process of the chip, since the positioning holes on the chip only contact the positioning posts on the consumable cartridge, and no effective mechanical constraint is formed between the two, there may also be a risk that the electrical connector directly falls off the cartridge body of the consumable cartridge. If the operator fails to notice that the electrical connector has fallen off the cartridge body of the consumable cartridge and directly installs the chip, it will cause the contacts on the chip to be not electrically connected to the contact pins in the printer, resulting in the failure to realize some functions of the chip and affecting the normal use of the chip.

[0084] In the prior art, a grounding terminal is provided on the back of the chip, and the electrical connector is electrically connected between the grounding terminal and the contact pin of the printer. The first end of the electrical connector is in electrical contact with the grounding terminal, and the first end of the electrical connector is elastic. After the chip is installed on the cartridge body of the consumable, since the positioning posts provided on the cartridge body at this time are not welded, that is, no welded portion is formed, the first end of the electrical connector will push one side of the chip away from the cartridge body of the consumable cartridge, causing the chip to be deflected. When the positioning posts provided on the cartridge body are welded subsequently, due to the deflection of the chip, the positioning posts are not welded in place, resulting in poor contact between the terminal provided on the back side of the chip and the first end of the electrical connector and unstable contact between the front terminal of the chip and the contact pin.

[0085] In view of this, the consumable cartridge provided by the present utility model, by providing a stop assembly, the stop assembly is used to realize the limiting function of the chip in the first direction, prevent the chip from moving away from the cartridge body in the first direction, and the stop assembly applies a second force to the chip, so that the chip is no longer in a free state in the first direction, thereby forming an effective mechanical constraint on the chip, which helps to improve the stability of chip installation and solve the problems that the chip is prone to fall off and deflect when pre-installed on the cartridge body.

[0086] The following describes the consumable cartridge provided by the embodiments of the present utility model with reference to the drawings.

[0087] Embodiment 1

[0088] Referring to Figure 1 and Figure 2 As shown, the embodiment of the present application provides a consumable cartridge, which is detachably installed in the installation unit 50 of the image forming apparatus. A contact pin 512 is provided in the installation unit 50. Specifically, the installation unit 50 is provided with a contact pin assembly 51. The contact pin assembly 51 includes a contact pin holder 511 and a contact pin 512 provided on the contact pin holder 511. The contact pin 512 includes a first contact pin and a second contact pin. The first contact pin can be one, two or more, and the second contact pin can be one, two or more.

[0089] At least one installation position 52 is provided in the installation unit 50. Each installation position 52 installs one consumable cartridge, and each installation position 52 is correspondingly provided with a contact pin assembly 51.

[0090] In this embodiment, the installation unit 50 is provided with four installation positions 52 for installing four consumable cartridges, and the four consumable cartridges can be respectively used for storing four different colors of ink, such as red, yellow, blue, and black.

[0091] Reference Figure 3 , Figure 4 and Figure 5 As shown in Figure 2 and Figure 5 , the present utility model provides a consumable cartridge, which includes: a cartridge body 10, a chip 20, an electrical connector 30, and a stop assembly 40. The outer wall of the cartridge body 10 has a placement portion 15; the chip 20 is disposed in the placement portion 15, and the chip 20 has a first contact portion 21, and the first contact portion 21 is located on the side of the chip 20 facing the cartridge body 10; the electrical connector 30 is disposed between the cartridge body 10 and the chip 20, and the electrical connector 30 has a first end and a second end. As shown in Figure 2 and Figure 5 , the first end of the electrical connector 30 abuts against the first contact portion 21, and the second end of the electrical connector 30 is electrically connected to the contact pin 512.

[0092] Reference Figure 3 , Figure 4 and Figure 5 As shown in

[0093] In the consumable cartridge provided by the present utility model, by providing the stop assembly 40, the stop assembly 40 is used to realize the limiting function of the chip 20 in the first direction, prevent the chip 20 from moving away from the cartridge body 10 in the first direction, and the stop assembly 40 applies a second force to the chip 20, so that the chip 20 is no longer in a free state in the first direction, thereby forming an effective mechanical constraint on the chip 20, which helps to improve the installation stability of the chip 20 and solve the problems that the chip 20 is prone to fall off and skew when pre-installed on the cartridge body 10.

[0094] The first end of the electrical connector 30 abuts against the first contact portion 21, and the first end of the electrical connector 30 applies a first force to the chip 20, aiming to improve the electrical connection stability between the electrical connector 30 and the chip 20, thereby improving the communication quality and communication stability between the chip 20 and the printer.

[0095] Considering the squeezing effect of the first end of the electrical connector 30 on the chip 20, it is easy to cause one side of the chip 20 to warp, resulting in the problem that the installation attitude of the chip 20 is shifted. In this application, a stop component 40 is provided to balance the second force of the first end of the electrical connector 30 on the chip 20. The second force is opposite to the first force exerted by the first end of the electrical connector 30 on the chip 20, so that the chip 20 maintains a state of balanced force. The stop component 40 presses the side edge of the chip 20 that is prone to warping, solving the problem that the installation attitude of the chip 20 is prone to shift, thereby solving the problem that stable communication between the chip 20 and the printer cannot be achieved.

[0096] Reference Figure 3 As shown, a coordinate system is established. The first direction is the thickness direction of the chip, and the first direction refers to the Y-axis direction; the second direction is the length direction of the chip, and the second direction refers to the X-axis direction; the third direction is the width direction of the chip, and the third direction refers to the Z-axis direction. Among them, the first direction, the second direction, and the third direction can be perpendicular to each other in pairs.

[0097] In the first embodiment, the first direction is consistent with the length direction of the consumable cartridge, the second direction is consistent with the width direction of the consumable cartridge, and the third direction is consistent with the height direction of the consumable cartridge.

[0098] In a possible implementation manner, reference Figure 3 and Figure 4 As shown, an ink outlet 17 and a handle 19 are further provided on the outer wall of the cartridge body 10. The ink outlet 17 is located at the bottom of the cartridge body 10, and the ink outlet 17 is used to supply ink to the printer. The handle 19 is located on the upper side of the placement portion 15, and the handle 19 is used to stop the cartridge body 10 to the installation unit 50.

[0099] In a possible implementation manner, reference Figure 3 and Figure 4 As shown, at least one positioning post 16 is further provided on the outer wall of the cartridge body 10. The positioning post 16 is located at the edge of the placement portion 15. The chip 20 has at least one positioning hole 22, and the positioning post 16 extends into the positioning hole 22.

[0100] In a possible implementation manner, the positioning hole 22 is located at the edge of the chip 20. The number of the positioning holes 22 is the same as that of the positioning posts 16, and the positions correspond to each other. When the chip 20 is installed on the placement portion 15, through the mutual cooperation of the positioning post 16 and the positioning hole 22, the positioning of the chip 20 in the second direction and the third direction is relative to the positioning of the cartridge body 10.

[0101] In a possible implementation, the number of positioning holes 22 can be four. Two of the positioning holes are respectively located at two side edges of the chip 20 along the second direction, i.e., along the X-axis, and the other two positioning holes are respectively located at two side edges of the chip 20 along the third direction, i.e., along the Z-axis. The number of positioning posts 16 can be four. Two of the positioning posts 16 are respectively located on the outer side walls of the placement portion 15 along the second direction, and the other two positioning posts 16 are respectively located on the outer side walls of the placement portion 15 along the third direction. The positions of the positioning posts 16 correspond to the positions of the positioning holes 22, so that the positioning posts 16 extend correspondingly into the positioning holes 22.

[0102] In other possible implementations, the number of the positioning posts 16 can also be two, three or more.

[0103] In a possible implementation, as shown in Figure 6 The chip 20 has a center line M1 extending along the third direction. The center line M1 divides the chip 20 into a first part 25 and a second part 26. One of the at least two stop structures abuts against the first part 25, and the other stop structure abuts against the second part 26. That is, one of the two stop structures is adjacent to the peripheral side of the first part 25 and applies a second acting force to the first part 25 of the chip 20; the other stop structure is adjacent to the peripheral side of the second part 26 and applies a second acting force to the second part 26 of the chip 20.

[0104] In this example, the center line M1 is the center line in the width direction of the chip 20. The center line M1 extends along the third direction, that is, the center line M1 extends along the height direction of the chip 20. Thus, the chip 20 is divided into two parts, where the first part 25 is located on the -X side and the second part 26 is located on the +X side.

[0105] In a possible implementation, as shown in Figure 6 , Figure 7 and Figure 8 The stop structure at least includes a first stop portion 41 and a second stop portion 42 arranged at intervals with the first stop portion 41. Along the first direction, the acting force applied by the first stop portion 41 to the chip 20 is opposite to the acting force applied by the first end of the electrical connector 30 to the chip 20, and the acting force applied by the first stop portion 41 to the chip 20 is greater than or equal to the acting force applied by the first end of the electrical connector 30 to the chip 20. In this example, the acting force direction applied by the first stop portion 41 to the chip 20 is along the -Y direction, and the acting force direction applied by the first end of the electrical connector 30 to the chip 20 is along the +Y direction.

[0106] As shown in Figure 7 and Figure 8As shown, the first stop portion 41 includes a first fixing portion 411 and a first biasing portion 412. One end of the first fixing portion 411 is connected to the box body 10, the other end of the first fixing portion 411 is connected to the first biasing portion 412, and the first biasing portion 412 abuts against the side of the chip 20 facing away from the box body 10.

[0107] The first fixing portion 411 and the first biasing portion 412 may be integrally connected as a whole structure, ensuring the structural strength of the first stop portion 41. The first biasing portion 412 is used to apply a force to the chip 20 against the first end of the electrical connector 30.

[0108] In a possible implementation manner, the first stop portion 41 may be in the shape of a buckle.

[0109] In this example, the force applied to the chip 20 by the first stop portion 41 is greater than or equal to the force applied to the chip 20 by the first end of the electrical connector 30, so as to balance the force applied to the chip 20 by the first end of the electrical connector 30, thereby preventing the tilting problem of the chip 20 during pre-installation.

[0110] In a possible implementation manner, referring to Figure 6 , Figure 7 and Figure 8 shown, the second stop portion 42 and the first stop portion 41 are arranged at intervals along the second direction; referring to Figure 9 shown, along the second direction, the distance between the first stop portion 41 and the first end of the electrical connector 30 is L1, and the distance between the second stop portion 42 and the first end of the electrical connector 30 is L2, where L1 < L2.

[0111] In order to improve the stability of the electrical connection between the first end of the electrical connector 30 and the chip 20, the first end of the electrical connector 30 is in the shape of a spiral spring, and one end of the spiral spring contacts the chip 20. In this example, the distance between the first stop portion 41 and the first end of the electrical connector 30 is the distance between the first stop portion 41 and the center position of the first end of the electrical connector 30, and the distance between the second stop portion 42 and the first end of the electrical connector 30 is the distance between the second stop portion 42 and the center position of the first end of the electrical connector 30.

[0112] Referring to Figure 6 , Figure 7 and Figure 8As shown, along the first direction, the force exerted by the first stop portion 41 on the chip 20 is opposite to the force exerted by the first end of the electrical connector 30 on the chip 20, and the force exerted by the second stop portion 42 on the chip 20 is opposite to the force exerted by the first end of the electrical connector 30 on the chip 20. In this example, the force exerted by the first stop portion 41 on the chip 20 is along the -Y direction, the force exerted by the second stop portion 42 on the chip 20 is along the -Y direction, and the force exerted by the first end of the electrical connector 30 on the chip 20 is along the +Y direction.

[0113] It is easy to understand that the second stop portion 42 is located farther from the first end of the electrical connector 30 than the first stop portion 41. In order to resist the elastic force exerted by the first end of the electrical connector 30 on the chip 20, according to the moment balance, and the force exerted by the second stop portion 42 on the chip 20 is less than the force exerted by the first stop portion 41 on the chip 20, to prevent the problem of the chip 20 being skewed due to the moment imbalance on both sides of the chip 20.

[0114] Along the first direction, when the chip 20 and the electrical connector 30 are in the pre-installed state with the consumable cartridge, the overall force on the chip 20 is more balanced, which can effectively avoid the problems of the chip 20 having an offset installation position or a skewed installation attitude in the prior art, or the potential risk of the electrical connector 30 or the chip 20 falling off the consumable cartridge, improve the communication quality and stability between the chip 20 and the printing device, and reduce the failure rate during the use of the chip 20 and improve the stability of user use.

[0115] Considering that the position where the first end of the electrical connector 30 jacks up the chip 20 is the side of the chip 20 close to the electrical connector 30, causing the chip 20 to be skewed. In this example, the first stop portion 41 and the second stop portion 42 are respectively located at opposite ends of the chip 20 along the second direction, i.e., the X-axis direction, so as to facilitate the forces exerted by the first stop portion 41 and the second stop portion 42 on the chip 20 at the same time to balance the force exerted by the first end of the electrical connector 30 to jack up the chip 20, and solve the problem of the first end of the electrical connector 30 squeezing the chip 20 and causing the chip 20 to be skewed.

[0116] Reference Figure 10 and Figure 11 As shown, the second stop portion 42 includes a second fixing portion 421 and a second force-applying portion 422. One end of the second fixing portion 421 is connected to the cartridge body 10, the other end of the second fixing portion 421 is connected to the second force-applying portion 422, and the second force-applying portion 422 abuts against the side of the chip 20 facing away from the cartridge body 10;

[0117] The position where the second force-applying portion 422 contacts the chip 20 and the position where the first force-applying portion 412 contacts the chip 20 are on the same surface. Such a structure ensures that under the action of the second force-applying portion 422 and the first force-applying portion 412, the problem of tilting of the chip 20 is prevented.

[0118] The second fixing portion 421 and the second force-applying portion 422 may be an integrally connected integral structure, ensuring the structural strength of the second stopping portion 42. The second force-applying portion 422 is used to apply a force to the chip 20 against the first end of the electrical connector 30. The second stopping portion 42 may be in the shape of a buckle.

[0119] In the consumable cartridge provided by the present application, by using the stopping structure to abut against a part of the chip 20 and applying a force toward the chip 20, it can be ensured that the first contact portion 21 of the chip 20 is stably in contact with the first end of the electrical connector 30, solving the problem that due to process limitations of welding, such as insufficient welding degree of the welding tooling to the positioning post 16 provided on the cartridge body 10, there is a gap between the first contact portion 21 of the chip 20 and the first end of the electrical connector 30, resulting in inability to connect and affecting the use of certain functions of the chip 20.

[0120] In a possible implementation manner, the first stopping portion 41 abuts against one of the first portion 25 and the second portion 26, the second stopping portion 42 abuts against the other of the second portion 26 and the first portion 25, and the first stopping portion 41 and the second stopping portion 42 respectively abut against different positions of the chip 20 and their projections along the thickness direction of the chip 20 do not overlap.

[0121] In a possible implementation manner, the first stopping portion 41 abuts against the first portion 25, and the second stopping portion 42 abuts against the second portion 26. Among them, the first stopping portion 41 is located on the circumferential side of the first portion 25, the second stopping portion 42 is located on the circumferential side of the second portion 26, and the first stopping portion 41 and the second stopping portion 42 may not be at the diagonal positions of the chip 20 nor on the center line M1 of the chip 20.

[0122] Taking the third direction, i.e., the Z-axis, as the projection direction, the projection of the first end of the electrical connector 30 is located between the projection of the first stopping portion 41 and the projection of the second stopping portion 42. Or, taking the second direction, i.e., the X-axis, as the projection direction, the projection of the first end of the electrical connector 30 is located between the projection of the first stopping portion 41 and the projection of the second stopping portion 42.

[0123] In a possible implementation manner, the first stopping portion 41 and the second stopping portion 42 are respectively located at both ends of the chip 20 along the second direction, improving the balance of the force on the chip 20.

[0124] In other possible implementation manners, refer to Figure 3 、 Figure 10and Figure 11 As shown, the stop structure further includes a third stop portion 43. The third stop portion 43 and the first stop portion 41 respectively abut against two diagonal positions of the chip 20. The direction of the force applied by the third stop portion 43 to the chip 20 is opposite to the direction of the force applied by the first end of the electrical connector 30 to the chip 20.

[0125] The chip 20 is generally rectangular, and one side of the chip 20 has a notch. The third stop portion 43 and the first stop portion 41 are located at both ends of the diagonal of the chip 20. The direction of the force applied by the third stop portion 43 to the chip 20 is along the -Y direction, and the direction of the force applied by the first end of the electrical connector 30 to the chip 20 is along the +Y direction.

[0126] In a possible implementation manner, the third stop portion 43 includes a third fixing portion 431 and a third force-applying portion 432. One end of the third fixing portion 431 is connected to the box body 10, the other end of the third fixing portion 431 is connected to the third force-applying portion 432, and the third force-applying portion 432 abuts against the side of the chip 20 facing away from the box body 10; the position where the third force-applying portion 432 contacts the chip 20 and the position where the first force-applying portion 412 contacts the chip 20 are on the same surface. Such a structure enables the third force-applying portion 432, the second force-applying portion 422, and the third force-applying portion 432 to be in the same plane, preventing the chip 20 from tilting away from the box body 10 at these three positions of the third stop portion 43, the second stop portion 42, and the first stop portion 41, ensuring that the surface of the chip 20 is parallel to the box body 10, thereby improving the stability of the electrical connection between the chip 20 and the printer through the stylus.

[0127] The third fixing portion 431 and the third force-applying portion 432 can be an integrally connected integral structure, ensuring the structural strength of the third stop portion 43. The third force-applying portion 432 is used to apply a force to the chip 20 to counteract the force of the first end of the electrical connector 30.

[0128] In a possible implementation manner, the third stop portion 43 can be in the shape of a buckle.

[0129] In a possible implementation manner, referring to Figure 8 and Figure 9 As shown, along the second direction: the distance between the third stop portion 43 and the first end of the electrical connector 30 is L3, where L1 < L3 < L2; along the third direction: the distance between the third stop portion 43 and the first end of the electrical connector 30 is L4, and the distance between the first stop portion 41 and the first end of the electrical connector 30 is L5, where L5 < L4.

[0130] According to L4 and L3, the shortest straight-line distance between the third stopper 43 and the first end of the electrical connector 30 can be calculated. According to L1 and L5, the shortest straight-line distance between the first stopper 41 and the first end of the electrical connector 30 can be calculated.

[0131] In this embodiment, the force exerted by the first stopper 41 on the chip 20 is F1, the force exerted by the second stopper 42 on the chip 20 is F3, and the force exerted by the third stopper 43 on the chip 20 is F4. According to the moment balance in the second direction and the moment calculation in the third direction, F4 < F3. This ensures that the chip 20 will not tilt, guaranteeing the communication effect between the chip 20 and the printer.

[0132] In a possible implementation manner, referring to Figure 8 and Figure 9 as shown, at least two of the first stopper 41, the second stopper 42, and the third stopper 43 are respectively located at different side edges of the placement portion 15. For example, the first stopper 41 and the second stopper 42 are respectively located at the two side edges of the placement portion 15 along the second direction, and the second stopper 42 and the third stopper 43 are respectively located at the two side edges of the placement portion 15 along the third direction.

[0133] In a possible implementation manner, in the third direction, the first stopper 41, the second stopper 42, and the third stopper 43 respectively abut against different positions of the chip 20, and their projections along the thickness direction of the chip 20 do not overlap. For example, the first stopper 41 and the second stopper 42 are distributed alternately and abut against the top edge of the chip 20, and the third stopper 43 abuts against the bottom edge of the chip 20. This helps to reduce the force on the first stopper 41 and the second stopper 42 and improve the service life of the first stopper 41 and the second stopper 42.

[0134] In a possible implementation solution not shown in a figure, in the third direction, one of the second stopper 42 and the third stopper 43 abuts against the first stopper 41 at the same position of the chip 20, and their projections in the third direction at least partially overlap. In the width direction of the chip 20, that is, along the Z-axis direction, it can be that the projections of the first stopper 41 and the third stopper 43 at least partially overlap, or it can also be that the projections of the second stopper 42 and the third stopper 43 at least partially overlap.

[0135] In a possible implementation, one or more of the first stop portion 41, the second stop portion 42, and the third stop portion 43 respectively abut against one or more diagonal positions of the chip 20. For example, the first stop portion 41, the second stop portion 42, and the third stop portion 43 are respectively located at three corner positions of the chip 20; or, the first stop portion 41 and the third stop portion 43 are respectively located at two diagonal positions of the chip 20, which helps to improve the balance of the force on the chip 20 and reduce the force on the first stop portion 41, the second stop portion 42, and the third stop portion 43.

[0136] In a possible implementation, referring to Figure 12 , Figure 13 and Figure 14 As shown, at least one positioning post 16 is further provided on the outer wall of the box body 10. The positioning post 16 is located at the edge of the placement portion 15. The chip 20 has at least one positioning hole 22. The positioning post 16 extends into the positioning hole 22. The end of the positioning post 16 away from the box body 10 has a welding portion 14, and the welding portion 14 abuts against the side of the chip 20 facing away from the box body 10. The welding portion 14 can prevent the chip 20 from detaching from the box body 10 in the first direction.

[0137] After the chip 20 and the electrical connector 30 are pre-installed in the box body 10, the end of the positioning post 16 provided on the box body 10 away from the box body 10 is melted by a welding tooling to form a welding portion 14, and the welding portion 14 abuts against at least a part of the chip 20. It should be noted that at this time, the stop structure still stops at least a part of the chip 20 and applies a force to the chip 20.

[0138] In other possible implementations, since the welding portion 14 abuts against at least a part of the chip 20, and at the same time the welding portion 14 also applies a certain force to the chip 20, the chip 20 is displaced in the first direction towards the box body 10, resulting in a small gap between the stop structure and the chip 20, that is, a small gap between the stop structure and the chip 20, for example, 0.1 mm.

[0139] In a possible implementation, all or part of the electrical connector 30 can be made of metal, metal alloy or other conductive materials.

[0140] In a possible implementation, referring to Figure 14 , Figure 15 and Figure 16As shown, the electrical connector 30 includes a base end portion 31, a transition portion 32, and an arm portion 33. The base end portion 31 and the arm portion 33 are connected by the transition portion 32. The base end portion 31 is configured as the first end of the electrical connector 30, and the arm portion 33 is configured as the second end of the electrical connector 30. Among them, at least part of the base end portion 31 is located in the placement portion 15, and part of the arm portion 33 is located in the placement portion 15. In the length direction of the consumable cartridge, at least part of the arm portion 33 protrudes from the cartridge body 10.

[0141] Reference Figure 5 As shown, at least one first contact portion 21 is provided on the surface of the chip 20 facing the cartridge body 10. The base end portion 31 is in contact with the first contact portion 21 to achieve electrical connection, and the arm portion 33 is in contact with the corresponding contact pin 512 of the contact pin assembly 51.

[0142] In a possible implementation manner, the base end portion 31 is configured as an elastic structure, such as a helical spring structure, and the arm portion 33 can be configured as a meandering structure.

[0143] In a possible implementation manner, the electrical connector 30 includes an extension portion 34. The transition portion 32 connects the base end portion 31 and the arm portion 33, and at least part of the base end portion 31 is arranged in a helical structure relative to the transition portion 32.

[0144] Reference Figure 14 、 Figure 15 and Figure 16 As shown, the transition portion 32 is arranged at an angle relative to the arm portion 33. The transition portion 32 can be linear or folded; the extension portion 34 is connected to one end of the arm portion 33 relative to the transition portion 32. The extension portion 34 can be arranged in a helical structure, or can be a structure combined with a helical structure and a linear structure. For example, one end of the extension portion 34 connected to the arm portion 33 is linear or folded, and the end of the extension portion 34 away from the arm portion 33 is helical. The helical structure of the extension portion 34 can be wound around the protrusion 151, and the protrusion 151 can be a convex column.

[0145] The first surface of the cartridge body 10 also has a receiving portion 18. Along the height direction of the consumable cartridge, the position of the receiving portion 18 is higher than that of the placement portion 15.

[0146] The placement portion 15 is provided with a stopper portion 152, and a groove 153 is formed in the stopper portion 152. The base end portion 31 is located in the groove 153. To facilitate the installation of the base end portion 31 in the groove 153, one side of the stopper portion 152 has an installation opening 154, and the installation opening 154 communicates between the groove 153 and the outside of the stopper portion 152, facilitating the installation of the base end portion 31 into the groove 153 through the installation opening 154.

[0147] At least a part of the transition part 32 and the arm part 33 is located in the receiving part 18. In the length direction of the consumable cartridge, the arm part 33 extends out of the cartridge body 10; at least a part of the base end part 31 is electrically connected to the first contact part 21, and at least a part of the arm part 33 is electrically connected to the first contact pin. At least a part of the arm part 33 is clamped in the receiving part 18, so that the arm part 33 can be limited in the width direction of the consumable cartridge.

[0148] Reference Figure 12 and Figure 13 As shown, in the length direction of the consumable cartridge, at least a part of the base end part 31 is shielded by the chip 20. In this example, at least a part of the base end part 31 and the transition part 32 are shielded by the chip 20, which can prevent the base end part 31 from being exposed outside the consumable cartridge, and prevent the base end part 31 from being scratched or damaged during the installation or use of the consumable cartridge, playing a certain protective role for the electrical connector 30.

[0149] In some examples, to ensure the safety of use, except for the base end part 31 and the arm part 33 on the electrical connector 30, the rest are coated or provided with an insulating layer.

[0150] Reference Figure 5 and Figure 15 As shown, the number of the electrical connectors 30 is equal to the number of the first contact parts 21, that is to say, each electrical connector 30 corresponds to a first contact part 21. In this embodiment, the number of the electrical connectors 30 is one, and the number of the first contact parts 21 is also one. The electrical connector 30 and the chip 20 can be connected by means of welding, bonding, abutting or stopping.

[0151] In a possible implementation manner, the chip 20 further includes a storage element 23. The storage element 23 can be disposed on the surface of the chip 20 facing the cartridge body 10, or the storage element 23 can also be disposed on the surface of the chip 20 facing away from the cartridge body 10. Wherein, the storage element 23 stores information of the chip 20. For example, the storage element 23 stores information such as the manufacturer information, the ink volume information, the consumable cartridge category information, and the ink color.

[0152] In a possible implementation manner, the surface of the chip 20 facing away from the cartridge body 10 has a second contact part 24. At least a part of at least one of the first contact part 21 and the second contact part 24 is electrically connected to the storage element 23.

[0153] In a possible implementation manner, both the first contact portion 21 and the second contact portion 24 are electrically connected to the storage element 23; alternatively, one of the first contact portion 21 and the second contact portion 24 is electrically connected to the storage element 23, and the other is not electrically connected to the storage element 23; alternatively, a part of the first contact portion 21 is electrically connected to the storage element 23, and another part of the first contact portion 21 is not electrically connected to the storage element 23; alternatively, a part of the second contact portion 24 is electrically connected to the storage element 23, and another part of the second contact portion 24 is not electrically connected to the storage element 23.

[0154] The first end of the electrical connector 30 and the chip 20 can be connected by means such as welding, pasting, abutting, and clamping, so as to improve the connection stability. When the consumable cartridge and the installation unit 50 are in the installed state, the first contact portion 21 is electrically connected to the first contact pin through the electrical connector 30, and the second contact portion 24 is electrically connected to the second contact pin.

[0155] 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 other than the first contact portion 21.

[0156] It should be noted that the ground terminal is used to receive the 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 the power supply is provided for the operation of the storage element 23 through this terminal; the reset terminal is used to reset the internal data of the storage element 23; the clock terminal is used to receive the clock signal; the data terminal is used to send or receive 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.

[0157] In other examples, when the chip 20 includes a ground terminal, a power supply terminal, a reset terminal, a clock terminal, a data terminal, a high-voltage terminal, and a detection 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, the data terminal, the high-voltage terminal, and the detection terminal, and the second contact portion 24 includes the remaining contact portions other than the first contact portion 21. It should be noted that the high-voltage terminal is used to detect whether the consumable cartridge is correctly installed in the printer. 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 other terminals, that is, the low-voltage terminals.

[0158] In this embodiment, the cartridge body 10 includes a first cartridge body 11, the placement portion 15 is located on one end surface of the first cartridge body 11 along the first direction, the inside of the first cartridge body 11 is used for storing ink, and the placement portion 15 is configured as a groove formed by being recessed toward the inside of the first cartridge body 11 along the first direction.

[0159] Example 2

[0160] Reference Figure 17 、 Figure 18 and Figure 19 As shown in [reference], in this example, the first direction is the thickness direction of the chip, and the first direction refers to the Y-axis direction; the second direction is the length direction of the chip, and the second direction refers to the X-axis direction; the third direction is the width direction of the chip, and the third direction refers to the Z-axis direction. Among them, the first direction, the second direction, and the third direction can be perpendicular to each other in pairs.

[0161] In this embodiment, the first stop portion 41 and the second stop portion 42 can be abutted against the diagonal positions of the chip 20. Among them, the first stop portion 41 abuts against the lower left corner position of the chip 20, and the second stop portion 42 abuts against the upper right corner position of the chip 20, improving the stability of the chip 20.

[0162] Reference Figure 17 、 Figure 18 and Figure 19 As shown in [reference], the cartridge 10 includes a second cartridge body 12 and a chip holder 13. The chip holder 13 is detachably disposed on the second cartridge body 12, and the placement portion 15 is located on the side of the chip holder 13 facing away from the second cartridge body 12. The inside of the second cartridge body 12 is used for storing ink.

[0163] In this embodiment, the second cartridge body 12 includes a tray 121 and an inner container 122. The inner container 122 includes a liquid containing portion 1221 and a connecting member 1222. The connecting member 1222 is connected to the liquid containing portion 1221, and the liquid containing portion 1221 is used for storing ink. The liquid containing portion 1221 and the connecting member 1222 are installed in the tray 121.

[0164] Reference Figure 19 and Figure 24 As shown in [reference], the connecting member 1222 has a locking portion 1223, and the chip holder 13 has a locked portion 131. The locked portion 131 and the locking portion 1223 are locked and connected to each other; the locked portion 131 is disposed on the side of the chip holder 13 facing away from the chip 20.

[0165] In a possible implementation manner, the locking portion 1223 can be a locking protrusion, and the locked portion 131 can be a locking groove adapted to the shape of the locking protrusion. Of course, in other possible implementation manners, the locked portion 131 can be a locking protrusion, and the locking portion 1223 can be a locking groove adapted to the shape of the locking protrusion. Exemplarily, the locking protrusion is a cross-shaped protrusion, and the locking groove is a cross-shaped groove. By inserting the locking protrusion into the locking groove, the locked portion 131 and the locking portion 1223 are locked and connected to each other, realizing the detachable connection between the chip holder 13 and the connecting member 1222, and the connection is stable, facilitating the installation and disassembly of the chip holder 13.

[0166] In this example, the placement part 15 is disposed on a side of the chip holder 13 facing away from the locking part 61.

[0167] Reference Figure 20 , Figure 21 and Figure 22 As shown in Figure 22 and Figure 23 , at least one positioning post 16 is further disposed on the outer wall of the chip holder 13. The positioning post 16 is located at the edge of the placement part 15. The chip 20 has at least one positioning hole 22. The positioning post 16 extends into the positioning hole 22. As shown in

[0168] , a welding part 14 is provided at one end of the positioning post 16 away from the box body 10. The welding part 14 abuts against a side of the chip 20 facing away from the box body 10. The welding part 14 can prevent the chip 20 from detaching from the box body 10 in the first direction.

[0169] After the chip 20 and the electrical connection member 30 are pre-installed in the box body 10, the positioning post 16 provided on the box body 10 is melted by a welding tooling to form the welding part 14. The welding part 14 abuts against at least a part of the chip 20. It should be noted that at this time, the stop structure still engages with at least a part of the chip 20 and applies a force to the chip 20.

[0170] The remaining structures of the second embodiment are the same as those of the first embodiment and will not be described herein again.

[0171] Embodiment Three

[0172] In this third embodiment, as shown in Figure 25 , Figure 26 , Figure 27 , two different stop structures are located on the center line M1.

[0173] Reference Figure 25 and Figure 28 , the center line M1 divides the chip 20 into a first part 25 and a second part 26; the center line M1 is the center line in the width direction of the chip 20. The center line M1 extends along the third direction, that is, the center line M1 extends along the height direction of the chip 20. Thus, the chip 20 is divided into two parts, where the first part 25 is located on the -X side and the second part 26 is located on the +X side.

[0174] In this example, the two different stop structures include a first stop portion 41 and a second stop portion 42, and the first stop portion 41 and the second stop portion 42 are spaced apart along the third direction, i.e., the Z-axis direction.

[0175] In a possible implementation manner, along the third direction, both the first stop portion 41 and the second stop portion 42 abut against the position of the center line of the chip 20. A part of the first stop portion 41 abuts against the first part 25, and another part of the first stop portion 41 abuts against the second part 26. Similarly, a part of the second stop portion 42 abuts against the first part 25, and another part of the second stop portion 42 abuts against the second part 26. This makes the overall force on the chip 20 more balanced and can effectively avoid the problems of the chip 20 having an offset in the installation position or a skew in the installation attitude in the prior art.

[0176] The remaining structures of the third embodiment are the same as those of the first embodiment and will not be described in detail here.

[0177] Embodiment Four

[0178] In this fourth embodiment, referring to Figure 29 、 Figure 30 and Figure 31 as shown, one of the first stop portion 41 and the second stop portion 42 abuts against a corner position of the chip 20, and the other of the second stop portion 42 and the first stop portion 41 abuts against the position of the center line of the chip 20.

[0179] In this example, the first stop portion 41 abuts against the left corner position at the top of the chip 20, and the second stop portion 42 is located at the bottom of the chip 20 and corresponds to the position of the center line M1 of the chip 20. This makes the overall force on the chip 20 more balanced and improves the stability of the chip 20.

[0180] In the third direction, the first end of the electrical connector 30 is located between the first stop portion 41 and the second stop portion 42, making the moment of the chip 20 balanced. By the abutting forces exerted on the chip 20 by the first stop portion 41 and the second stop portion 42, problems such as the chip 20 warping and skewing can be prevented.

[0181] Embodiment Five

[0182] In the third direction, referring to Figure 32 、 Figure 33 、 Figure 34 and Figure 35 as shown, any one or two of the first stop portion 41, the second stop portion 42, and the third stop portion 43 are located on the center line M1. The center line M1 corresponds to any one or two of the first stop portion 41, the second stop portion 42, and the third stop portion 43.

[0183] In this example, the center line M1 corresponds to the third stop portion 43, that is, the third stop portion 43 is located on the center line M1. Along the second direction, that is, the X-axis direction, the first end of the electrical connector 30 is located between the first stop portion 41 and the second stop portion 42.

[0184] In other possible implementation manners, it may also be that the first stop portion 41 and the second stop portion 42 are located on the center line M1, or the first stop portion 41 and the third stop portion 43 are located on the center line M1.

[0185] In this application, by providing the first stop portion 41, the second stop portion 42, and the third stop portion 43 on the cartridge 10 for abutting against the chip 20, the second stop portion 42 is located at a position on the cartridge 10 closer to the first end of the electrical connector 30 than the first stop portion 41, and the force exerted by the second stop portion 42 on the chip 20 is used to offset the force exerted by the first end of the external electrical connector 30 on the chip 20, so that when the chip 20 and the electrical connector 30 are in a pre-installed state with the cartridge 10, the overall force on the chip 20 is more balanced, effectively avoiding the problems of the chip 20 being displaced in the installation position or skewed in the installation posture in the prior art, or the potential risk of the electrical connector 30 or the chip 20 falling off the cartridge 10 of the consumable cartridge, improving the communication quality and stability between the chip 20 and the printing device, and reducing the failure rate during the use of the chip 20.

[0186] In this application, by using the first stop portion 41, the second stop portion 42, and the third stop portion 43, the second stop portion 42 abuts against a part of the chip 20 and exerts a force towards the cartridge 10 on the chip 20, which can ensure stable contact between the first contact portion 21 of the chip 20 and the first end of the electrical connector 30, overcoming the problem in the prior art that due to limitations in the welding process, for example, the insufficient welding degree of the welding tooling on the positioning post 16 provided on the cartridge 10, there is a gap between the first contact portion 21 of the chip 20 and the first end of the electrical connector 30, resulting in the inability to connect, which affects the normal use of certain functions of the chip 20.

[0187] In this application, the number of the original positioning posts 16 provided on the cartridge 10 can be reduced. If any component in the chip 20 or the electrical connector 30 fails or is damaged, the repair or replacement process of the chip 20 and the electrical connector 30 can be simplified, the user's usage cost can be reduced, and the user experience can be improved.
