Description

[0001] This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office on April 18, 2024, with application number 202420813922.3 and application name “Electrical Connection Assembly and Consumable Box”, all contents of which are incorporated by reference in this application.

[0002] The utility model relates to the technical field of consumable boxes in imaging devices, in particular to an electrical connection component and a consumable box. Background Art

[0003] Printers and other image forming devices are common office equipment that provide convenience for modern office work. The image forming device is equipped with a replaceable consumable box containing ink, and the printer can spray ink onto paper to form the text or pattern to be printed. The consumable box is provided with a chip, which is used to communicate with the contact pins in the installation unit of the printer. The chip is provided with multiple terminals. During the long-term use of the existing consumable box, some conductive foreign matter (such as ink drops or metal wires or metal debris, etc.) may adhere to the surface of the consumable box. If the foreign matter adheres between the terminals, it will cause a short circuit between the two, and then the chip will be burned or the printer will not recognize the machine.

[0004] To solve the above problems, in the related art, one or more target terminals are set on the side of the chip facing away from the stylus assembly of the printer, and a conductive member is added. The conductive member is provided with an external contact portion on the side facing the stylus assembly, and the external contact portion is used to electrically connect with the target stylus in the stylus assembly. The conductive member is also electrically connected to the target terminal of the chip by welding. However, during the welding process between the conductive member and the target terminal, the molten solder is easily dropped between the conductive member and the target terminal of the chip, resulting in uneven distribution of solder between the target terminal and the external contact portion, resulting in cold solder joints, poor contact or loss of contact between the chip and the stylus assembly, and further causing the problem of unstable communication or communication interruption between the chip and the printer, affecting the normal use of the consumable box and reducing the safety of users.

[0117] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0118] The consumable box is a component in the image forming device that needs to be replaced frequently. The image forming device can be an inkjet printer, and the corresponding consumable box is an ink cartridge that stores ink; the image forming device can also be a laser printer, and the corresponding consumable box is a processing box, a developer box, a powder box, etc. that stores toner.

[0119] The chip set on the box body of the consumables box is used to store information such as the manufacturer, ink volume, consumables box category, ink color, related processing procedures and communication procedures, etc. In order to prevent charged foreign objects from falling on the chip and causing a short circuit, some target terminals are set on the back surface of the chip, which is the side of the chip facing the box body, and the remaining terminals are set on the front surface of the chip, which is the side of the chip facing away from the box body, thereby reducing the problem of charged foreign objects falling on the chip and causing a short circuit.

[0120] In order to make the target terminal located on the rear surface of the chip contact with the corresponding target contact pin to achieve electrical connection, in some schemes, a conductive member is provided on the box body of the consumable box, and the first end of the conductive member is electrically connected to the target terminal of the chip, and the second end of the conductive member is used to electrically connect to the target contact pin of the image forming device, thereby achieving electrical connection between the target terminal and the target contact pin in the image forming device and realizing a communication effect.

[0121] In the existing consumables box, the conductive part and the target terminal of the chip are electrically connected by welding. However, during the welding process of the conductive part and the target terminal, the molten solder will splash between the conductive part and the target terminal of the chip, causing uneven distribution of solder between the target terminal and the external contact part, resulting in cold soldering, resulting in poor contact or loss of contact between the chip and the contact pin assembly, and further causing the problem of unstable communication or communication interruption between the chip and the image forming device, affecting the normal use of the consumables box and reducing the safety of users.

[0122] In view of this, in the present application, by improving the structure of the connecting component, a connecting arm is provided on the connecting piece, and along the first direction, there is a distance between the second end of the connecting arm and the main body, that is, the second end of the connecting arm is away from the main body in the first direction, wherein the second end of the connecting arm is provided with an external contact portion, and the chip has a first contact portion on the first surface facing the connecting component. When the chip and the connecting component are in an installed state, the second end of the connecting arm applies an abutting force toward the first contact portion, so that the external contact portion contacts the first contact portion. This can effectively avoid the problem of poor contact or loss of contact between the target terminal and the chip in the prior art due to improper chip installation or external environmental factors such as vibration and shaking during use, thereby improving the communication quality and stability between the chip and the image forming device.

[0123] In addition, in the utility model, the chip and the connecting parts are connected in a detachable manner, which can effectively avoid the cold solder joint problem caused by welding the conductive parts to the chip terminals in the prior art, reduce the failure rate of the chip during use, and improve the user experience. If any component of the chip or the connecting parts fails or is damaged, only the single component that fails or is damaged needs to be repaired or replaced, thereby reducing the user's usage cost and improving the user experience.

[0124] For a better description of the consumables cartridge components, refer to Figure 4 As shown, a coordinate system is established: wherein the width direction of the consumable box is the X-axis direction, the length direction of the consumable box is the Y-axis direction, and the height direction of the consumable box is the Z-axis direction, wherein the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0125] In this example, the first direction is the direction indicated by the Y axis, the second direction is the direction indicated by the X axis, and the third direction is the direction indicated by the Z axis. The angles between the first direction, the second direction, and the third direction may be 90°.

[0126] refer to Figure 1 , Figure 2 and Figure 3 As shown, the consumable box 100 is detachably mounted on the mounting unit 10 of the image forming device. The mounting unit 10 is provided with a contact pin assembly 20. The contact pin assembly 20 includes a first contact pin 21 and a second contact pin 22. The first contact pin 21 may be one, two or more, and the second contact pin 22 may be one, two or more.

[0128] refer to Figure 4 and Figure 5 As shown, an electrical connection component provided in the first embodiment of the utility model is applied to the consumable box 100, and the electrical connection component 200 includes: a connecting component 210 and a chip 220, the connecting component 210 includes a main body 219 and at least one connecting arm 211, the first end 211a of the connecting arm 211 is connected to the main body 219, and along the first direction, there is a distance between the second end 211b of the connecting arm 211 and the main body 219.

[0129] refer to Figure 4 , Figure 5 and Figure 6 As shown, the chip 220 has a first contact portion 222, and the first contact portion 222 is located on the first surface 221 of the chip 220. The first surface 221 is the side of the chip 220 facing the connecting component 210. When the chip 220 and the connecting component 210 are in an installed state, the second end 211b of the connecting arm 211 applies abutting force toward the first contact portion 222, so that the second end 211b of the connecting arm 211 is in electrical contact with the first contact portion 222.

[0130] The utility model provides an electrical connection component, by improving the structure of a connection component 210, along a first direction, there is a distance between the second end 211b of a connection arm 211 and a main body 219, that is, the second end 211b of the connection arm 211 is away from the main body 219 in the first direction, and a first surface 221 of a chip 220 faces the connection component 210, and the first surface 221 has a first contact portion 222. When the electrical connection component is installed in a consumable box 100, the second end 211b of the connection arm 211 applies an abutting force toward the first contact portion 222, so that the second end 211b of the connection arm 211 contacts the first contact portion 222, which can effectively avoid the problem of poor contact or loss of contact between a target terminal and the chip 220 due to improper installation of the chip 220 or external environmental factors such as vibration and shaking during use, thereby improving the communication quality and stability of the chip 220 and the image forming device.

[0131] In this example, refer to Fig.10 As shown, the main body 219 may be in the shape of an annular sheet, such as a rectangular sheet.

[0132] In one possible implementation, reference Figure 6 , Fig. 9 and Fig.10 As shown, the second end 211b of the connecting arm 211 is provided with an inner contact portion 212, which abuts against the first contact portion 222 and is in electrical contact with the first contact portion 222. The inner contact portion 212 is a part of the structure of the second end 211b, for example, it can be a conductive bump or a conductive bump, etc., which plays a role in improving the conductive performance.

[0133] In this embodiment, reference Figure 6 , Figure 8 and Fig. 9 As shown, the number of connecting arms 211 is preferably two, and each connecting arm 211 has a first end 211a and a second end 211b. The first end 211a is used to connect to the main body 219 of the connecting component 210, and the second end 211b is constructed to be away from the main body 219 in the -Y direction. The second end 211b of the connecting arm 211 is provided with an inner contact portion 212. When the chip 220 and the connecting component 210 are in an installed state, the second end 211b of the connecting arm 211 squeezes the first contact portion 222, that is, the second end 211b applies abutting force to the first contact portion 222 in the -Y direction, so that the inner contact portion 212 and the first contact portion 222 are stably maintained in contact, thereby improving the communication quality and stability of the chip 220 and the image forming device.

[0134] In one possible implementation, reference Figure 4 , Figure 5 and Figure 7As shown, along the first direction, the chip 220 has a shielding area that coincides with the projection of the connecting component 210 , and the first contact portion 222 and the connecting arm 211 are located in the shielding area.

[0135] It is easy to understand that when observing the electrical connection assembly along the first direction, that is, along the +Y direction, the area where the connection component 210 is blocked by the chip 220 is the blocking area, that is, the area where the chip 220 and the connection component 210 overlap is the blocking area. When observing the electrical connection assembly along the first direction, the blocking area is not visible, that is, the blocking area is blocked by the chip 220. Among them, the first contact portion 222 and the connecting arm 211 are located in the blocking area, so that the chip 220 can protect the inner contact portion 212 of the connecting arm 211 and the first contact portion 222.

[0136] In one possible implementation, reference Figure 6 , Fig. 9 and Fig.10 As shown, the connection component 210 further includes a coupling portion 213 , which is connected to the main body 219 , electrically connected to the connection arm 211 , and has an external contact portion 213 d . The chip 220 also has an exposed area 228 for exposing the coupling portion 213 .

[0137] When observing the electrical connection component from the first direction, i.e., the +Y direction, the area of ​​the connection component 210 that is not blocked by the chip 220 is the exposed area 228, that is, the area where the connection component 210 does not overlap with the chip 220 is the exposed area 228. It can be understood that when observing the electrical connection component from the first direction, i.e., the +Y direction, the exposed area 228 can be seen, and the exposed area 228 is not blocked by the chip 220.

[0138] In one possible implementation, reference Figure 6 , Fig.10 and Fig.11 As shown, the area of ​​the shielding region may be larger than the area of ​​the exposed region 228 , so that a larger area of ​​the connecting component 210 may be shielded by the chip 220 , thereby effectively protecting the connecting component 210 .

[0139] In one possible implementation, reference Fig.10 As shown, a hollow portion 217 is provided on the main body 219 , and in the first direction, the projection of the connecting arm 211 overlaps with the projection of the hollow portion 217 .

[0140] In a possible implementation, all or part of the connecting component 210 may be made of metal, metal alloy or other conductive materials.

[0141] In a possible implementation, the chip 220 has a split state separated from the connecting component 210 and an installed state installed on the connecting component 210; when the chip 220 is in the split state, the distance between the second end 211b of the connecting arm 211 and the main body 219 along the first direction is H1; Fig.11 As shown, when the chip 220 is in the installed state, the distance between the second end 211 b of the connecting arm 211 and the main body 219 along the first direction is H2, wherein H2

[0142] It is easy to understand that when the chip 220 is not installed on the connecting component 210, that is, the chip 220 and the connecting component 210 are in a separated state, the height of the second end 211b of the connecting arm 211 from the connecting component 210 is greater than the height of the second end 211b of the connecting arm from the connecting component 210 when the chip 220 and the connecting component 210 are in an installed state.

[0143] refer to Figure 6 , Fig. 9 and Fig.10 As shown, when the chip 220 is not installed on the connecting component 210, the second end 211b of the connecting arm 211 is away from the main body 219 in the -Y axis direction. When the chip 220 is installed on the connecting component 210, the second end 211b of the connecting arm is deformed and moved toward the direction close to the main body 219 due to the force along the first direction. If the external force is large, the second end 211b of the connecting arm can be displaced into the hollow portion 217. Since the connecting arm 211 is made of deformable material, it can apply abutting force along the -Y direction toward the first contact portion 222 provided on the chip 220 while deforming in the +Y direction, so that the inner contact portion 212 provided on the second end 211b of the connecting arm 211 can stably abut against the first contact portion 222, thereby ensuring a stable electrical connection between the chip 220 and the connecting component 210.

[0144] In a possible implementation, along the first direction, the coupling portion 213 is exposed through the exposed area 228 , and the coupling portion 213 extends obliquely toward the chip 220 . In the second direction, the coupling portion 213 is disposed on one side of the main body 219 .

[0145] In one possible implementation, reference Fig.10 and Fig.11 ​As shown, the coupling portion 213 is in an inclined sheet shape, one end of the coupling portion 213 is connected to the main body 219, and the other end of the coupling portion 213 is inclined toward the direction close to the chip 220. In the second direction, that is, the direction indicated by the X-axis, in the second direction, the portion of the coupling portion 213 inclined toward the chip 220 at least partially overlaps with the projection of the chip 220. It is easy to understand that, because the coupling portion 213 is inclined, the coupling portion 213 and the main body 219 are not in the same plane.

[0146] In a possible implementation, the chip 220 further has a second surface 223 , and the second surface 223 faces away from the connecting component 210 .

[0147] One end of the coupling portion 213 is connected to the main body 219, and the other end of the coupling portion 213 is not connected to the main body 219. The coupling portion 213 is configured to be inclined toward a second surface 223 close to the chip 220 and facing away from the connecting component 210, and along the second direction, a portion of the coupling portion 213 at least partially overlaps with the projection of the second surface 223.

[0148] refer to Fig.10 and Fig.11 As shown, an angle θ is formed between the extension direction of the coupling portion 213 and the plane where the main body portion 219 is located, 0<θ<90°. For example, the angle θ can be 15°, 30°, 45° or 60°, etc. Such a structure enables the coupling portion 213 to have a certain elastic force in the first direction, which can improve the electrical connection effect between the coupling portion 213 and the first contact pin 21 and improve the stability of the connection.

[0149] In one possible implementation, the coupling portion 213 is constructed to include a first portion 213a and an inclined portion 213c, one end of the first portion 213a is connected to the main body portion 219, and the other end of the first portion 213a is connected to the inclined portion 213c, and in a first direction, one end of the inclined portion 213c is constructed to be inclined toward a second surface 223 close to the chip 220 and facing away from the connecting component 210, and along the second direction, a portion of the inclined portion 213c at least partially overlaps with the projection of the second surface 223.

[0150] In one possible implementation, reference Figure 7 and Fig.12 As shown, the second surface 223 has a second contact portion 224; the chip 220 has a center line L extending along a third direction, the center line L divides the chip 220 into a first area 225 and a second area 226, the second contact portion 224 and part of the first contact portion 222 are located in the first area 225, and the remaining part of the first contact portion 222 is located in the second area 226.

[0151] The center line L is an auxiliary line for the purpose of better introducing the structure of the electrical connection assembly. The center line L extends along the third direction, that is, the length direction of the center line L is parallel to the Z axis, and the center line L is the center line of the chip 220 in the second direction. The position of the center line L is the center position of the chip 220 in the second direction, and the center line L is parallel to the width direction of the chip 220.

[0152] In the second direction, the second contact portion 224 and a portion of the first contact portion 222 are located in the first area 225, and the exposed area 228 and another portion of the first contact portion 222 are located in the second area 226. When the connecting component 210 and the chip 220 are in the installed state, a portion of the connecting arm 211 abuts against the first contact portion 222 located in the first area 225, and another portion of the connecting arm 211 abuts against the first contact portion 222 located in the second area 226. It should be noted that by providing the first contact portion 222 in the first area 225 and the second area 226, respectively, when the first contact portion 222 in one of the first area 225 and the second area 226 fails, the first contact portion 222 in the other of the first area 225 and the second area 226 can also contact the inner contact portion 212, thereby ensuring normal communication between the chip and the image forming device.

[0153] In addition, by respectively providing the first contact portion 222 in the first area 225 and the second area 226, and the connecting arms 211 respectively abutting against the corresponding first contact portion 222, it can be ensured that after the consumable box is loaded into the image forming device, when the contact pin assembly contacts the second contact portion 224 of the chip 220 and applies a force to the chip 220, the force on the first area 225 and the second area 226 of the chip 220 is more balanced, thereby avoiding the problem that the chip 220 is offset due to different forces applied by the contact pins in different areas due to the mismatch in the distribution of the number of contacts in the first area 225 and the second area 226, resulting in poor contact or unstable contact between the second contact portion 224 and the second contact pin 22.

[0154] In one possible implementation, reference Fig.10 , Fig.11 and Fig.12As shown, there are at least two connecting arms 211; when the chip 220 is in the installed state, one of the at least two connecting arms 211 abuts against the first contact portion 222 located in the first area 225, and the other of the at least two connecting arms 211 abuts against the first contact portion 222 located in the second area 226. In this example, there are two connecting arms 211, one connecting arm 211 abuts against the first contact portion 222 located in the first area 225, and the other connecting arm 211 abuts against the first contact portion 222 located in the second area 226, to achieve dual connection communication. Even if the communication of one of the connecting arms 211 fails, the other connecting arm 211 can still achieve communication, ensuring normal communication between the chip and the image forming device.

[0155] It should be noted that, in another example, the number of the connecting arms 211 may be one or more, and the number of the first contact portions 222 is consistent with the number of the connecting arms 211 , and the positions thereof correspond to each other.

[0156] In one possible implementation, reference Fig.10 and Fig.11 As shown, the main body 219 has a void 214, and the chip 220 further includes a storage element 227, which is disposed on the first surface 221 or the second surface 223, wherein the first surface 221 faces the connecting component 210, and the second surface 223 faces away from the connecting component 210, and the first surface 221 has a first contact portion 222, and the second surface 223 has a second contact portion 224. At least a portion of at least one of the first contact portion 222 and the second contact portion 224 is electrically connected to the storage element 227.

[0157] In one possible implementation, both the first contact portion 222 and the second contact portion 224 are electrically connected to the storage element 227; or, one of the first contact portion 222 and the second contact portion 224 is electrically connected to the storage element 227, and the other is not electrically connected to the storage element 227; or, a portion of the first contact portion 222 is electrically connected to the storage element 227, and another portion of the first contact portion 222 is not electrically connected to the storage element 227; or, a portion of the second contact portion 224 is electrically connected to the storage element 227, and another portion of the second contact portion 224 is not electrically connected to the storage element 227.

[0158] The storage element 227 is located in the air-avoiding hole 214 , and the connecting arm 211 is located on the inner wall of the air-avoiding hole 214 .

[0159] When the chip 220 and the connecting component 210 are in an installed state, the avoidance hole 214 can avoid the storage element 227 to avoid the problem that the chip 220 and the connecting component 210 cannot be installed due to structural interference.

[0160] At least one of the first contact portion 222 and the second contact portion 224 includes a ground contact portion. For example, the first contact portion 222 includes a ground contact portion; or the second contact portion 224 includes a ground contact portion.

[0161] The utility model also provides a consumables box, which can be detachably installed in the image forming device, referring to Figure 1 , Figure 2 and Figure 3 As shown, the image forming device has a mounting unit 10, the mounting unit 10 includes a stylus assembly 20, and the stylus assembly 20 includes at least one first stylus 21. Figure 4 and Figure 5 As shown, the consumable box 100 includes the above-mentioned electrical connection assembly 200; the connecting arm 211 is electrically connected to the first contact portion 222 of the chip 220, and the coupling portion 213 of the connecting component 210 is electrically connected to the first contact pin 21. The second end 211b of the connecting arm 211 may be electrically connected to the first contact pin 21.

[0162] In this embodiment, the consumable box further includes a first box body 110, the first box body 110 has a placement portion 111, and the electrical connection assembly 200 is disposed in the placement portion 111 of the first box body 110. The first box body 110 contains ink, and the placement portion 111 is configured as a groove formed by being recessed toward the inside of the first box body 110 along a first direction.

[0163] In one possible implementation, reference Fig.11 As shown, the connecting component 210 includes at least one support arm 215, the support arm 215 is connected to the main body 219, the support arm 215 extends along a first direction toward a direction away from the main body 219, the support arm 215 extends into the placement portion 111, the support arm 215 is provided with a locked portion 216, and at least one locking portion 112 is provided in the placement portion 111, and the locked portion 216 is snap-connected with the locking portion 112.

[0164] refer to Figure 4 and Figure 5 As shown, the placement portion 111 includes an inner wall 111a and an outer wall 111b, and the locking portion 112 may be disposed on the inner wall 111a of the placement portion 111. The support arm 215 may be configured to extend in a first direction away from the main body portion 219, with reference to Figure 7 , Figure 8 and Fig. 9As shown, when the connecting component 210 is installed in the placement portion 111 of the first box body 110, the support arm 215 extends into the placement portion 111, and the locked portion 216 provided on the support arm 215 is connected to the locking portion 112, thereby avoiding the problem in the prior art that the first contact portion 222 on the chip 220 and the inner contact portion 212 provided on the connecting arm 211 of the connecting component 210 are misaligned or in poor contact due to the displacement of the installation position of the connecting component 210, or the problem that the connecting component 210 is easily to fall off directly from the consumable box. For example, if the operator neglects to notice that the connecting component 210 has fallen off from the consumable box and directly installs the chip 220, some terminals on the chip 220 will not be connected to the image forming device for communication, making some functions of the chip 220 unable to be realized. This solution can improve the communication quality and stability between the chip 220 and the image forming device.

[0165] In one possible implementation, the locking portion 112 may be a claw, and the locked portion 216 may be a slot that cooperates with the claw. In this example, the locked portion 216 is a through hole, thereby facilitating the engagement and connection between the locked portion 216 and the locking portion 112.

[0166] In a possible implementation, the connecting component 210 includes two support arms 215, which are respectively connected to two opposite inner walls of the air avoidance hole 214, and the number of the locking portions 112 is consistent with the number of the support arms 215, and the positions correspond to each other.

[0167] refer to Figure 4 , Figure 5 and Figure 6 As shown, the first positioning portions 113 are arranged at intervals on the outer side wall 111b of the placement portion 111, and when the connecting component 210 is installed on the placement portion 111 of the first box body 110, the first positioning portions 113 are connected to the second positioning portions 218 arranged on the connecting component 210. It should be noted that in this embodiment, the number of the first positioning portions 113 is preferably four, and in other possible implementations, the number of the first positioning portions 113 can also be multiple.

[0168] The chip 220 is provided with a third positioning portion 229 . When the chip 220 and the placement portion 111 are in an installed state, the third positioning portion 229 is connected to the first positioning portion 113 provided on the placement portion 111 , thereby achieving an effect of positioning the chip 220 .

[0169] When the electrical connection assembly is installed in the consumable box, the connection component 210 is first assembled with the placement portion 111, and then the chip 220 is assembled with the connection component 210. It should be noted that if the connection component 210 is assembled with the placement portion 111 before the chip 220, the connection component 210 cannot be assembled with the placement portion 111 due to the small space between the chip 220 and the placement portion 111. Therefore, the installation order of the connection component 210 and the chip 220 is to assemble the connection component 210 with the placement portion 111 first, and then assemble the chip 220 with the connection component 210.

[0170] refer to Fig. 9 and Fig.10 As shown, at least one side edge of the main body 219 further has a notch 2191, and the notch 2191 and the coupling portion 213 are located on the same side of the main body 219. The notch 2191 is used to avoid the first positioning portion 113, and the notch 2191 does not contact the first positioning portion 113.

[0171] In one possible implementation, reference Figure 4 and Figure 5 As shown, a avoidance hole 116 is also provided in the placement portion 111. Along the first direction, the projection of the connecting arm 211 of the connecting component 210 and the avoidance hole 116 at least partially overlap. The positions of the avoidance hole 116 and the connecting arm 211 of the connecting component 210 correspond to each other. The avoidance hole 116 is configured to form a depression from the outer side wall 111b in the opposite direction of the first direction. In this example, the avoidance hole 116 is a blind hole. By providing the avoidance hole 116, when the connecting component 210 is installed on the placement portion 111 of the first box body 110, the connecting arm 211 is displaced toward the placement portion 111 close to the first box body 110 under the action of external force, and the interference between the connecting arm 211 and the outer side wall 111b of the placement portion 111 is avoided. When the chip 220 and the connecting component 210 are in the installation state, in the second direction, the projections of the connecting arm 211 and the connecting component 210 at least partially overlap or completely overlap.

[0172] In addition, by providing the avoidance hole 116, the distance that the connecting arm 211 is displaced toward the placement portion 111 close to the first box body 110 under external action can be limited, that is, the connecting arm 211 is displaced until it abuts against the inner wall surface of the avoidance hole 116, thereby preventing the connecting arm 211 from being out of contact with the first contact portion 222 of the chip 220 due to the large displacement distance of the connecting arm 211.

[0173] refer to Figure 6 , Figure 7 and Fig.11As shown, the connection component 210 or the chip 220 can be assembled with the placement portion 111 by welding, pasting, abutting, clamping, etc. When the electrical connection assembly and the consumable box are in the installed state, the first contact portion 222 contacts the inner contact portion 212 on the connecting arm 211, a portion of the storage element 227 enters the placement portion 111 through the avoidance hole 214, and a portion of the coupling portion 213 is exposed through the exposed area 228.

[0174] When the consumable box and the installation unit 10 are in the installation state, the first contact pin 21 is electrically connected to the coupling portion 213 , that is, the first contact portion 222 is electrically connected to the first contact pin 21 through the connecting component 210 , and the second contact portion 224 is electrically connected to the second contact pin 22 .

[0175] In some examples, when the chip 220 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, and a data terminal, the first contact portion 222 may be one or more of the ground terminal, the power terminal, the reset terminal, the clock terminal, and the data terminal. The second contact portion 224 includes the remaining contact portions except the first contact portion 222.

[0176] It should be noted that the ground terminal is used to receive the ground potential; the power terminal is used to receive the power potential different from the ground potential (such as 3.6V, or 3.3V), and this terminal provides power for the operation of the storage element 227; the reset terminal is used to reset the internal data of the storage element 227; the clock terminal is used to receive the clock signal; the data terminal is used to send or receive the data signal, and is also used to detect a short circuit between the data terminal and at least one of the clock terminal, the reset terminal, and the power terminal.

[0177] In other examples, when the chip 220 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, a data terminal, a high-voltage terminal, and a detection terminal, the first contact portion 222 may be one or more of the ground terminal, the power terminal, the reset terminal, the clock terminal, the data terminal, the high-voltage terminal, and the detection terminal, and the second contact portion 224 includes the remaining contact portions except the first contact portion 222. It should be noted that the high-voltage terminal is used to detect whether the consumable box is correctly loaded into the image forming device. The detection terminal is used to detect whether a short circuit occurs between the high-voltage terminal of the chip and at least one of the remaining terminals, i.e., the low-voltage terminals.

[0178] The inclined portion 213c has an external contact portion 213d electrically connected to the first contact pin 21. It should be noted that the coupling portion 213 is at least partially exposed through the exposed area 228, so as to realize the electrical connection between the external contact portion 213d and the first contact pin 21. By configuring one end of the inclined portion 213c to be inclined toward the chip 220, in the prior art, even when the thickness of the chip 220 increases, the first contact pin 21 can be stably electrically connected to the external contact portion 213d, and the problem of interruption of communication between the chip 220 and the image forming device caused by the coupling portion 213 being far from the second surface 223 of the chip 220 in the prior art can be avoided. For example, if the thickness of the chip 220 is too large, the edge of the exposed area 228 will squeeze the first contact pin 21, causing the first contact pin 21 to be compressed in a direction away from the second surface 223 of the chip 220, thereby causing the first contact pin 21 to be out of contact with the external contact portion 213d, and the problem of interruption of communication between the chip 220 and the image forming device.

[0179] Embodiment 2

[0180] The second embodiment of the present invention provides an electrical connection assembly, comprising: a connection component 210 and a chip 220, wherein, with reference to Fig.13 and Fig.14 As shown, the connection component 210 is different from the first embodiment in that: a bending arm 2192 is provided on at least one side edge of the main body 219 along the third direction, and the bending arm 2192 extends toward the chip 220 along the first direction.

[0181] When an automated production line is used to assemble electrical connection components in a consumable box, when the connection components 210 are being transported, adjacent connection components 210 are easily overlapped with each other due to external environmental factors such as vibration or shaking, causing inconvenience to the automated assembly. In this embodiment, a bending arm 2192 is provided on at least one side edge of the main body 219 along the third direction, i.e., the Z-axis direction, so that a barrier can be formed in adjacent connection components 210 to prevent two adjacent connection components 210 from overlapping with each other.

[0182] In one possible implementation, reference Fig.15 and Fig.16 As shown, both side edges of the main body 219 along the third direction are provided with bending arms 2192, which can enhance the effect of preventing two adjacent connecting components 210 from overlapping each other.

[0183] The bending arm 2192 may be a flange structure formed at the edge of the main body 219 .

[0184] In a possible implementation, one or more second positioning portions 218 in the connecting component 210 are configured as a snap-fit ​​structure, that is, when the connecting component 210 is installed with the placement portion 111, Fig.16 , Fig.17 and Fig.18 As shown, one or more second positioning portions 218 are mutually engaged with the first positioning portion 113. For example, the second positioning portion 218 may be a through hole in the shape of a water drop, the second positioning portion 218 has an opening connected to the air avoidance hole 214, the second positioning portion 218 may be located on the inner wall of the air avoidance hole 214, and the first positioning portion 113 is a protruding columnar structure.

[0185] Of course, in other possible implementations, the second positioning portion 218 may also be located on the outer wall of the air avoidance hole 214. Alternatively, there are multiple second positioning portions 218, one of the multiple second positioning portions 218 is located on the inner wall of the air avoidance hole 214, and the other second positioning portions 218 are located on the outer wall of the air avoidance hole 214.

[0186] In one possible implementation, due to insufficient connection strength or lack of connection between the second positioning portion 218 of the connecting component 210 and the first positioning portion 113 of the placement portion 111, or due to vibration or shaking of the connecting component 210, the installation position of the connecting component 210 may be easily shifted, resulting in the inner contact portion 212 on the connecting arm 211 and the first contact portion 222 of the chip being misaligned or in poor contact when the chip 220 is installed with the connecting component 210, thereby causing the problem of unstable communication connection between the chip and the printer.

[0187] The present application, by constructing one or more second positioning portions 218 in the connecting component 210 as a snap-on structure, can effectively avoid the problem in the prior art that the second positioning portion 218 of the connecting component 210 and the first positioning portion 113 of the placement portion 111 have insufficient connection strength or lack of connection, or there is a problem in the connecting component 210 that causes the installation position of the connecting component 210 to shift due to vibration or shaking, which leads to misalignment or poor contact between the inner contact portion 212 on the connecting arm 211 and the first contact portion 222 of the chip when the chip 220 is installed with the connecting component 210, thereby causing the chip 220 and the printer to have an unstable communication connection.

[0188] refer to Fig.13 As shown, the utility model further provides a consumables box, which can be detachably installed in an image forming device, and the consumables box 100 includes the above-mentioned electrical connection assembly 200.

[0190] In this embodiment, one or more second positioning portions 218 in the connecting component 210 are configured as a snap-fit ​​structure, that is, when the connecting component 210 is installed with the placement portion 111, one or more second positioning portions 218 are snap-fitted with the first positioning portion 113. For example, the second positioning portion 218 may be a through hole in a water drop shape, and the first positioning portion 113 may be a protruding columnar structure.

[0191] By constructing the second positioning portion 218 as a snap-on structure, it is possible to effectively avoid the problem in the prior art that before the first positioning portion 113 is melted, the second positioning portion 218 of the connecting component 210 and the first positioning portion 113 of the placement portion 111 are not connected with sufficient strength or have no connection, thereby posing a risk of the first chip frame 170 directly falling off from the first box body 110 of the consumable box. If the operator neglects to notice that the first chip frame 170 has fallen off from the first box body 110 and directly installs the chip 220, the terminals on the chip 220 will not be electrically connected to the contact pins in the printing device, making some functions of the chip 220 impossible to achieve, affecting the normal use of the chip 220.

[0216] The remaining structures of the electrical connection assembly and the communication method between the chip 220 and the contact pin assembly are the same as those in the first embodiment and will not be described in detail.

[0217] Embodiment 7

[0218] This embodiment is different from the first embodiment in that, Fig.46 and Fig.47 As shown, in this embodiment, the connecting component 210 includes a main body portion 219 and at least one connecting arm 211 , and the connecting component 210 also includes a coupling portion 213 .

[0219] Along the first direction, the coupling portion 213 is exposed through the exposed area 228 , and the coupling portion 213 and the main body portion 219 are located in the same plane. Alternatively, in the third direction, the coupling portion 213 is parallel to the first surface 221 .

[0220] In this embodiment, the coupling portion 213 is configured as a plane. The coupling portion 213 may be located on the plane where the main body 219 is located. The coupling portion 213 is used to be electrically connected to the first contact pin 21 .

[0221] The remaining structures of the electrical connection assembly and the communication method between the chip and the contact pin assembly are the same as those in the first embodiment and will not be described in detail here.

[0222] Embodiment 8

[0223] The difference between the sixth embodiment and the first embodiment is that Fig.48 and Fig.49 As shown, a recessed portion 150 is further provided on the outer side wall 111 b of the seating portion 111 . The recessed portion 150 is recessed toward the inner side wall 111 b of the seating portion 111 . Exemplarily, the recessed portion 150 may be in the shape of a rectangular groove.

[0224] Along the first direction, a portion of the coupling portion 213 extends obliquely toward the chip 220 , and another portion of the coupling portion 213 extends obliquely toward the plane where the main body portion 219 is located.

[0225] refer to Fig.50 and Fig.51 As shown, the connecting component 210 includes a coupling portion 213, one end of the coupling portion 213 is connected to the main body portion 219, and the other end of the coupling portion 213 is provided with a second portion 213b, the second portion 213b extends toward a plane close to the main body portion 219, and the second portion 213b of the coupling portion 213 abuts against the inner wall surface of the recessed portion 150.

[0226] When the connecting component 210 and the placement portion 111 of the consumable box are in an installed state, a portion of the second portion 213b enters the recessed portion 150 and abuts against the first inner wall 151 of the recessed portion 150. The recessed portion 150 is used to limit the deformation of the second portion 213b of the coupling portion 213 along the third direction.

[0227] refer to Fig.51 , Fig.52 and Fig.53As shown, after the electrical connection assembly and the consumable box are installed, the consumable box is loaded into the image forming device, the first contact pin 21 is electrically connected to the outer contact portion 213d of the inclined portion 213c, and a force in the direction opposite to the first direction is applied to the inclined portion 213c. At this time, since the second portion 213b of the coupling portion 213 abuts against the first inner wall 151, the second portion 213b of the coupling portion 213 can be effectively prevented from being disengaged from the first contact pin 21 and the outer contact portion 213d due to excessive deformation, thereby avoiding affecting the communication quality between the chip and the image forming device. This embodiment can ensure the stability of the communication between the chip and the image forming device.

[0228] The remaining structures of the electrical connection assembly and the communication method between the chip and the contact pin assembly are the same as those in the first embodiment and will not be described in detail.

[0229] Embodiment 9

[0230] The difference between the ninth embodiment and the first embodiment is that Fig.54 , Fig.55 ,and Fig.56 As shown, in this embodiment, the connecting component 210 includes a main body 219 and at least one connecting arm 211, and the connecting component 210 also includes a coupling portion 213. In this embodiment, the placement portion 111 is provided with a first positioning portion 113, and the top of the first positioning portion 113 has a welding portion 1131, that is, the end of the first positioning portion 113 away from the placement portion 111 has the welding portion 1131, and the welding portion 1131 has the effect of preventing the chip 220 and the connecting component 210 from escaping from the placement portion 111.

[0231] The connecting component 210 is detachably disposed as an independent part between the placement portion 111 and the chip 220 relative to the chip 220 . The top of the first positioning portion 113 has a welding portion 1131 , and the welding portion 1131 is at least partially in contact with the chip 220 .

[0232] When installing the electrical connection component to the consumable box, first install the connection component 210 to the placement portion 111, and then install the chip 220. The chip 220 is installed to the placement portion 111 so that the second positioning portion 218 of the chip 220 corresponds to the position of the first positioning portion 113, instead of pre-installing the connection component 210 and the chip 220 as a whole, which makes it easier to reduce the difficulty of installation.

[0233] In a possible implementation, the welding portion 1131 may be circular, and the diameter of the welding portion 1131 is larger than the inner diameter of the third positioning portion 229 , thereby preventing the third positioning portion 229 from falling out.

[0234] In this embodiment, reference Fig.57 , Fig.58 and Fig.59As shown, the chip 220 and the connecting component 210 are installed with the consumable box through an auxiliary tool 300. The auxiliary tool 300 includes a main body 310, a heating part 320 and an abutment part 330. The main body 310 has a hollow part 311, and the abutment part 330 is located in the hollow part 311. An elastic member 340 is provided inside the hollow part 311. One end of the elastic member 340 is connected to the inner wall of the hollow part 311, and the other end is connected to the abutment part 330. The heating part 320 is located on the side of the auxiliary tool 300 facing the chip 220. A through portion 321 is provided in the heating part 320 for partially exposing the abutment part 330. Under the elastic force of the elastic member 340, the abutment part 330 protrudes from the surface of the heating part 320. Under the action of external force, the abutment part 330 moves in the through portion 321.

[0235] In this example, the elastic member 340 may be, for example, a spring, the abutting portion 330 may be spherical, the main body 310 may be cubical, and the hollow portion 311 is a cavity formed inside the main body 310. The heating portion 320 may generate heat by electrical heating, and is used to abut against the first positioning portion 113, so that the top of the first positioning portion 113 forms a fusion portion 1131.

[0236] The installation process of the chip 220 and the connecting component 210 to the placement portion 111 of the consumable box by means of the auxiliary tool 300 is as follows:

[0237] First, the connecting component 210 is installed on the placement portion 111 of the consumable box, the first positioning portion 113 passes through the second positioning portion 218 of the connecting component 210 , and the chip 220 is placed on the connecting component 210 . At this time, the first positioning portion 113 passes through the third positioning portion 229 of the chip 220 .

[0238] Then, the auxiliary tool 300 is moved toward the direction close to the consumable box. First, the abutment portion 330 in the auxiliary tool 300 applies a force toward the chip 220 along the first direction to squeeze the electrical connection component, that is, squeeze the chip 220 and the connecting component 210 along the first direction, so that the electrical connection component is displaced toward the direction close to the placement portion 111, so that the first positioning portion 113 protrudes further from the second surface 223 of the chip 220.

[0239] Next, the heating portion 320 of the auxiliary tool 300 abuts against and heats the first positioning portion 113 , and the first positioning portion 113 melts after being heated. The melted first positioning portion 113 forms a welding portion 1131 , which is used to fix the electrical connection component to the placement portion 111 of the consumable box.

[0240] It should be noted that as the first positioning portion 113 gradually melts, the height of the first positioning portion 113 decreases, and a welding portion 1131 is formed at the top of the first positioning portion 113, and the heating portion 320 of the auxiliary tool 300 gradually approaches the second surface 223 of the chip 220. When the welding portion 1131 is formed, the heating portion 320 contacts the second surface 223 of the chip 220. At this time, the abutment portion 330 is squeezed into the hollow portion 311.

[0241] When the auxiliary tool 300 is working, the connecting arm 211 is deformed along the first direction toward the direction close to the placement portion 111, and the inner contact portion 212 on the connecting arm 211 abuts against the first contact portion 222 of the chip 220, and in the second direction, the projection of the connecting arm 211 and the connecting component 210 at least partially overlap or completely overlap, ensuring a stable electrical connection effect between the connecting component 210 and the chip 220, and ensuring the stability of communication.

[0242] refer to Fig.60 , Fig.61 and Fig.62 As shown, the connecting component 210 includes two support arms 215, which are connected to the main body 219 and extend into the placement portion 111. The support arms 215 are provided with a locked portion 216. At least one locking portion 112 is provided in the placement portion 111, and the locked portion 216 is snap-connected with the locking portion 112.

[0243] refer to Fig.63 and Fig.62 As shown, the locked portion 216 provided on the support arm 215 is connected to the locking portion 112, so as to avoid the problem in the prior art that the first contact portion 222 on the chip 220 and the inner contact portion 212 of the connecting component 210 are misaligned or in poor contact due to the displacement of the installation position of the connecting component 210, or the connecting component 210 is easily and directly detached from the consumable box. For example, if the operator neglects to notice that the connecting component 210 has detached from the consumable box and directly installs the chip 220, the terminals on the chip 220 will not be electrically connected to the contact pins in the image forming device, so that some functions of the chip 220 cannot be realized. The present solution can improve the communication quality and stability between the chip 220 and the image forming device.
