Description

[0001] This application claims the priority of a Chinese patent application with the application number 202421686740.0 and the application title "Consumable Cartridge" filed with the National Intellectual Property Administration on July 16, 2024, the entire content of which is incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of consumable cartridges in imaging devices, and particularly to a consumable cartridge. Background Art

[0003] A consumable cartridge is a detachable part widely used in printing devices. The consumable cartridge contains ink, and the printing device can spray the ink onto the paper to form the text or pattern to be printed. A chip is provided on the consumable cartridge, and the chip is used for communication connection with the contact pins in the installation unit of the printing device. There are multiple terminals on the chip. During long-term use of the existing consumable cartridge, some conductive foreign matters (such as ink droplets, metal wires, or metal debris) may adhere to the surface of the consumable cartridge. If the foreign matter adheres between the terminals, it will cause a short circuit between the two, and then the chip will be burned out or the imaging device will not recognize the machine.

[0004] To solve the above problems, in the related art, one or more target terminals are arranged on the side of the chip facing away from the contact pin assembly of the imaging device, and a connection component is added. The connection component is a conductive part, and an outer contact part is provided on the side of the conductive part facing the contact pin assembly, and the outer contact part is used for electrical connection with the target contact pins in the contact pin assembly. There is an installation position on the consumable cartridge, and the chip and the conductive part are installed in this installation position. A clamping buckle is provided on the conductive part for snap-fitting connection with the clamping protrusion provided on the inner wall of the installation position. However, inaccurate assembly of the clamping buckle of the conductive part and the clamping protrusion will cause the position deviation or inclination of the conductive part, resulting in misalignment or poor contact between the conductive part and one or more target terminals on the chip after the conductive part and the chip are installed, and then causing problems such as unstable communication or communication interruption between the chip and the imaging device, affecting the normal use of the consumable cartridge and reducing the safety of user use.

[0073] 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 part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0074] The consumable cartridge is a component that needs to be frequently replaced in the image forming apparatus. The consumable cartridge is installed in the installation unit of the image forming apparatus. The image forming apparatus can be an inkjet printer, and the corresponding consumable cartridge is an ink cartridge storing ink; the image forming apparatus can also be a laser printer, and the corresponding consumable cartridges are a processing cartridge, a developing cartridge, a toner cartridge, etc. storing toner.

[0075] To prevent some conductive foreign object ink droplets, metal wires, metal chips, etc. from possibly adhering to the surface of the consumable cartridge, causing a short circuit between the terminals of the chip, as well as the situation where the chip is burned out or the image forming apparatus does not recognize the machine, generally, a connecting component is added between the chip and the body of the consumable cartridge. The connecting component is located at the installation position of the consumable cartridge. The outer contact portion is provided on one side of the connecting component facing the contact pin assembly, and the outer contact portion is used for electrically connecting with the target contact pin in the contact pin assembly. The connecting component and the body of the consumable cartridge are connected through a snap protrusion and a snap buckle.

[0076] Limited by the size of the inner wall of the installation position and the setting position of the snap protrusion, the snap buckle of the connecting component and the snap protrusion are prone to problems such as insufficient connection strength or inaccurate assembly, such as incorrect installation. During the automated assembly process of the consumable cartridge, if there are human or external environmental factors such as vibration or shaking, it is easy to cause the problem of the connecting component falling off.

[0077] In addition, during the installation process of the connecting component and the consumable cartridge, if the force applied to the snap buckle of the connecting component is too large, the snap buckle will be damaged, and then the connecting component and the consumable cartridge cannot be installed, affecting the normal communication between the subsequent chip and the image forming apparatus and the realization of the corresponding functions of the chip.

[0078] In view of this, the consumable cartridge provided by the present utility model realizes a tight fit by matching the second contact portion 311a provided on the connecting component 310 with the first contact portion 210 of the body 100, improves the accuracy and stability of the assembly of the connecting component 310, reduces the problem that the position of the connecting component 310 is shifted or tilted, helps to improve the stability of communication between the chip 320 and the image forming apparatus, and prevents problems such as communication interruption and affecting the use of the consumable cartridge.

[0079] The following describes the consumable cartridge provided by the embodiments of the present utility model with reference to the drawings.

[0080] For better description of the consumable cartridge assembly, refer to Figure 5 As shown, a coordinate system is established: The direction in which the connecting component 310 is installed with the placement portion 110 of the consumable cartridge is defined as the first direction, the second direction and the third direction are respectively orthogonal to the first direction. Among them, the first direction refers to the direction indicated by the Y axis, the second direction refers to the direction indicated by the X axis, and the third direction refers to the direction indicated by the Z axis. The included angles between the first direction, the second direction and the third direction can be 90°. In other possible implementation manners, the included angles between the first direction, the second direction and the third direction can be 80° - 100°, for example, they can be 80°, 85°, 90°, 95° or 100°.

[0081] In this embodiment, the width direction of the consumable cartridge is the X-axis direction, the length direction of the consumable cartridge is the Y-axis direction, and the height direction of the consumable cartridge is the Z-axis direction, where the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0082] Reference Figure 1 、 Figure 2 and Figure 3 As shown in the figures, the consumable cartridge is detachably installed in the installation unit 10 of the image forming apparatus. The installation unit 10 is provided with a probe assembly 20, and the probe assembly 20 includes a first probe 21 and a second probe 22. The first probe 21 can be one, two, or more, and the second probe 22 can be one, two, or more.

[0083] Embodiment 1

[0084] Reference Figure 4 、 Figure 5 and Figure 6 As shown in the figures, a consumable cartridge provided in Embodiment 1 of the present utility model includes a main body 100. The main body 100 includes a placement portion 110. In the first direction, the placement portion 110 is configured to form a depression toward the consumable cartridge direction. The placement portion 110 includes a rear wall 111, an inner wall 112, and an outer wall 113. In the first direction, there is an included angle between the inner wall 112 and the outer wall 113. In the second direction, the rear wall 111 is parallel to the outer wall 113, and the inner wall 112 is respectively connected to the outer wall 113 and the rear wall 111.

[0085] The consumable cartridge further includes a locking component and an electrical connection component 300. The locking component includes at least two groups of locking members 200 arranged at intervals on the placement portion 110. The locking member 200 includes a first contact portion 210. The electrical connection component 300 is installed on the placement portion 110. The electrical connection component 300 includes a connecting member 310. As shown in the figures, the connecting member 310 has at least two locked members 311 arranged at intervals. The locked member 311 includes a second contact portion 311a, and the second contact portion 311a is used to cooperate with the first contact portion 210. Figure 7 and Figure 8 The locking member 200 forms a first area for contacting the second contact portion 311a, and the locked member 311 forms a second area for contacting the first contact portion 210. The cross-sectional dimension of the first area is less than or equal to the cross-sectional dimension of the second area, so that the locking member 200 and the corresponding locked member 311 are tightly fitted to achieve the fixed installation of the connecting member 310 and the placement portion 110.

[0086] The locking member 200 forms a first area for contacting the second contact portion 311a, and the locked member 311 forms a second area for contacting the first contact portion 210. The cross-sectional dimension of the first area is less than or equal to the cross-sectional dimension of the second area, so that the locking member 200 and the corresponding locked member 311 are tightly fitted to achieve the fixed installation of the connecting member 310 and the placement portion 110.

[0087] The consumable cartridge provided by the present utility model realizes an interference fit by mating the second contact portion 311a provided on the connecting member 310 with the first contact portion 210 of the body 100, improving the accuracy and stability of the assembly of the connecting member 310, reducing the problem of the position of the connecting member 310 shifting or tilting, contributing to improving the stability of communication between the chip 320 and the image forming apparatus, and preventing problems such as communication interruption and affecting the use of the consumable cartridge.

[0088] The tight fit in this application includes an interference fit or a transition fit.

[0089] Reference Figure 5 and Figure 6 As shown, the placement portion 110 has a center line M1, which is parallel to the Z-axis. Along the second direction, the placement portion 110 is divided by the center line M1 into a left portion 114 and a right portion 115.

[0090] In a possible implementation manner, as shown in the reference Figure 6 There are two sets of locking members 200. At least two sets of locking members 200 can be arranged at intervals on the rear wall 111 of the placement portion 110. The two sets of locking members 200 are respectively arranged in the left portion 114 and the right portion 115. Each set of locking members 200 includes a plurality of first components 220, and the first contact portion 210 is provided on the first component 220.

[0091] In a possible implementation manner, along the second direction, the plurality of first components 220 are arranged at intervals. The plurality of first components 220 include at least one left component 222 and at least one right component 223. The left component 222 or the right component 223 is provided on the inner wall 112. In the second direction, the right component 223 and the left component 222 are arranged at intervals from each other, that is, there is a gap S between the left component 222 and the right component 223.

[0092] In a possible implementation manner, the first contact portion 210 is located on the side surface of the first component 220 along the second direction; each of the first components 220 has a first surface 221, and the first surfaces 221 of at least two first components 220 arranged at intervals face each other. The first contact portion 210 is located on the first surface 221, and the cross-sectional dimension of the first region is configured as the distance between two mutually facing first surfaces 221.

[0093] Reference Figure 6 As shown, both the left component 222 and the right component 223 have a first surface 221. In the second direction, the first surface of the left component 222 and the first surface 221 of the right component 223 face each other.

[0094] In this example, the first contact portions 210 are respectively located on the corresponding first surfaces 221 of the left member 222 and the right member 223. That is, the region formed between the first surface 221 of the left member 222 and the first surface 221 of the right member 223 is defined as the first region formed by the locking member 200. In the second direction, the distance between the first surface 221 of the left member 222 and the first surface 221 of the right member 223 is the cross-sectional dimension of the first region.

[0095] Reference Figure 7 and Figure 8 As shown, the connecting member 310 includes a main body portion 316 and at least two support arms 312 connected to the main body portion 316. The support arms 312 extend in the first direction towards the direction close to the main body 100, and the locking member 311 is formed on the corresponding support arms 312.

[0096] In a possible implementation manner, an avoidance hole 316a is provided in the main body portion 316, and the support arms 312 are connected to the inner wall of the avoidance hole 316a. The connecting member 310 has a center line M2, which is parallel to the Z-axis. In the second direction, the connecting member 310 is divided into a first side portion 317 and a second side portion 318 by the center line M2.

[0097] In this embodiment, the number of the support arms 312 is preferably two. The two support arms 312 are respectively arranged in the first side portion 317 and the second side portion 318, and the support arms 312 are configured to extend in the first direction away from the main body portion 316.

[0098] In a possible implementation manner, the support arms 312 have a second surface 3121 and a third surface 3122. The second surfaces 3121 of the two support arms 312 face away from each other, and the third surfaces 3122 of the two support arms 312 face each other; both the second surface 3121 and the third surface 3122 have a second contact portion 311a. The cross-sectional dimension of the second region is configured as the distance between the second surface 3121 and the third surface 3122. Among them, the second surface 3121 faces away from the avoidance hole 316a, and the third surface 3122 faces towards the avoidance hole 316a.

[0099] In a possible implementation manner, reference Figure 6 、 Figure 7 and Figure 8As shown, the locked member 311 is formed on each support arm 312. In this embodiment, the locked member 311 is the support arm 312. The locked member 311 includes a second contact portion 311a. The second contact portions 311a are respectively located on the second surface 3121 and the third surface 3122 of each support arm 312. That is, the area between the second surface 3121 and the third surface 3122 of each support arm 312 is the second area formed by the second contact portion 311a. Then, the cross-sectional dimension of the second area is the distance between the second surface 3121 and the corresponding third surface 3122 in the second direction.

[0100] It should be noted that the dimension of the first area formed by the locking member 200 is less than or equal to the dimension of the second area formed by the second contact portion 311a. That is, in the second direction, the distance between at least one left member 222 and at least one right member 223 is less than or equal to the thickness of the support arm 312.

[0101] During the process of the connecting member 310 being inserted into the placement portion 110, each locked member 311 is correspondingly inserted into each group of locking members 200. That is, the support arm 312 is gradually inserted into the gap S between at least one left member 222 and at least one right member 223. Therefore, the second contact portion 311a provided on the second surface 3121 and the third surface 3122 of the support arm 312 contacts the first contact portion 210 provided on the first surface 221 of the left member 222 and the right member 223.

[0102] Since in the second direction, the thickness of the support arm 312 is greater than or equal to the distance between the left component 222 and the right component 223, as the support arm 312 gradually enters the gap S, the tightening force on the support arm 312 gradually increases. When the connecting component 310 is completely installed on the placement part 110, the support arm 312 is completely accommodated in the gap S. At this time, the tightening force on the support arm 312 is the largest, thereby realizing a tight fit between the support arm 312 and the left component 222 and the right component 223, that is, by means of a tight fit between each locked part 311 and each corresponding set of locking parts 200, thereby realizing the fixed installation of the connecting component 310 on the placement part 110, avoiding the situation in the prior art where due to the offset of the installation position of the connecting component 310 or the damage of a part of the fixing structure of the connecting component 310, the first electrical contact part 321 on the chip 320 is in misalignment or poor contact with the inner contact part 313b1 provided on the connecting arm 313 in the connecting component 310, or the problem that the connecting component 310 is likely to directly fall off the consumable cartridge. For example, if the operator fails to notice that the connecting component 310 has fallen off the consumable cartridge and directly installs the chip 320, it will cause some terminals on the chip 320 to fail to be electrically connected to the corresponding communication connection of the probe in the image forming apparatus, resulting in the inability to realize some functions of the chip 320. This solution can improve the communication quality and stability between the chip 320 and the image forming apparatus.

[0103] The connecting component 310 further includes at least one connecting arm 313. The first end 313a of the connecting arm 313 is connected to the connecting component 310. Along the first direction, there is a distance between the second end 313b of the connecting arm 313 and the connecting component 310.

[0104] Reference Figure 4 and Figure 5 As shown, the electrical connection assembly 300 further includes a chip 320. The chip 320 has a first electrical contact part 321. When the chip 320 and the connecting component 310 are in the installed state, the second end 313b of the connecting arm 313 applies a pressing force towards the first electrical contact part 321, so that the second end 313b of the connecting arm 313 is in electrical contact with the first electrical contact part 321.

[0105] The chip 320 has a first electrical contact part 321. The first electrical contact part 321 is located on the first surface 322 of the chip 320. The surface of the chip 320 facing the connecting component 310 is the first surface 322. When the chip 320 and the connecting component 310 are in the installed state, the second end 313b of the connecting arm 313 applies a pressing force towards the first electrical contact part 321, so that the second end 313b of the connecting arm 313 is in electrical contact with the first electrical contact part 321.

[0106] In the consumable cartridge provided by the present utility model, through structural improvement of the connecting component 300 of the electrical connection component, in the first direction, there is a spacing between the second end 313b of the connecting arm 313 and the main body portion 316, that is, the second end 313b of the connecting arm 313 is far from the main body portion 316 in the first direction. The first surface 322 of the chip 320 faces the connecting component 310, and the first electrical contact portion 321 is located on the first surface 322. When the electrical connection component 300 is installed in the consumable cartridge, the second end 313b of the connecting arm 313 applies a pressing force towards the first electrical contact portion 321, and the second end 313b of the connecting arm 313 presses the first electrical contact portion 321, so that the second end 313b of the connecting arm 313 contacts the first electrical contact portion 321, which can effectively avoid problems such as poor contact or disconnection between the target terminal in the image forming apparatus and the chip 320 due to the chip 320 being not properly installed, or external environmental factors such as vibration and shaking during use, thereby improving the communication quality and communication stability between the chip 320 and the image forming apparatus.

[0107] Reference Figure 7 and Figure 8 As shown, the main body portion 316 can be in the shape of an annular sheet, such as a rectangular sheet, etc.

[0108] In a possible implementation manner, reference Figure 7 and Figure 8 As shown, an inner contact portion 313b1 is provided at the second end 313b of the connecting arm 313. The inner contact portion 313b1 abuts against the first electrical contact portion 321 and is in electrical contact with the first electrical contact portion 321. The inner contact portion 313b1 is a part of the structure of the second end 313b, and can be, for example, a conductive bump or a conductive block, etc., which plays a role in improving the conductive performance.

[0109] In this embodiment, reference Figure 7 and Figure 8 As shown, the number of the connecting arms 313 is preferably two. Each connecting arm 313 has a first end 313a and a second end 313b. The first end 313a is used to connect with the main body portion 316 of the connecting component 310. The second end 313b is configured to be far from the main body portion 316 in the -Y direction. An inner contact portion 313b1 is provided at the second end 313b of the connecting arm 313. Reference Figure 4 and Figure 5 As shown, when the chip 320 and the connecting component 310 are in the installed state, the second end 313b of the connecting arm 313 presses the first electrical contact portion 321, that is, the second end 313b applies a pressing force towards the first electrical contact portion 321 in the -Y axis direction, so that the inner contact portion 313b1 and the first electrical contact portion 321 stably maintain contact, thereby improving the communication quality and communication stability of the communication between the chip 320 and the image forming apparatus.

[0110] In a possible implementation manner, referring to Figure 5 and Figure 7 as shown, the connecting component 310 further includes a coupling portion 319. The coupling portion 319 is connected to the main body portion 316. The coupling portion 319 is electrically connected to the connecting arm 313. The coupling portion 319 has an outer contact portion 319a. The chip 320 further has a notch 325 for the coupling portion 319 to expose.

[0111] When observing the electrical connection component 300 from the first direction, i.e., the +Y direction, the area of the connecting component 310 not blocked by the chip 320 is exposed from the notch 325. It can be understood that when observing the electrical connection component 300 from the first direction, i.e., the +Y direction, the notch 325 and the coupling portion 319 can be seen, and the coupling portion 319 is not blocked by the chip 320.

[0112] In a possible implementation manner, all or part of the connecting component 310 can be made of metal, metal alloy or other conductive materials.

[0113] In a possible implementation manner, referring to Figure 4 , Figure 5 and Figure 7 as shown, the chip 320 has a split state separated from the connecting component 310 and an installation state installed on the connecting component 310. When the chip 320 is in the split state, the distance between the second end 313b of the connecting arm 313 and the main body portion 316 in the first direction is H1. When the chip 320 is in the installation state, the distance between the second end 313b of the connecting arm 313 and the main body portion 316 in the first direction is H2, where H2 < H1.

[0114] It is easy to understand that when the chip 320 is not installed on the connecting component 310, that is, when the chip 320 and the connecting component 310 are in the split state, the distance between the second end 313b of the connecting arm 313 and the main body portion 316 is greater than the distance between the second end 313b of the connecting arm and the main body portion 316 when the chip 320 and the connecting component 310 are in the installation state.

[0115] In a possible implementation manner, along the first direction, the coupling portion 319 is exposed through the notch 325, and at least part of the coupling portion 319 extends obliquely towards the chip 320. In the second direction, the coupling portion 319 is arranged on one side of the main body portion 316.

[0116] In a possible implementation manner, referring to Figure 5 and Figure 7As shown, the coupling part 319 is in the shape of an inclined sheet. One end of the coupling part 319 is connected to the main body part 316, and the other end of the coupling part 319 is inclined towards the direction close to the chip 320. In the second direction, i.e., the direction indicated by the X-axis, in the second direction, the projection of the coupling part 319 and the chip 320 at least partially overlap. Since the coupling part 319 is inclined, the coupling part 319 and the main body part 316 are not in the same plane.

[0117] In a possible implementation manner, referring to Figure 4 and Figure 5 As shown, the chip 320 also has a second surface 323. The second surface 323 of the chip 320 and the first surface 322 of the chip 320 are opposite surfaces of the chip 320, and the second surface 323 faces away from the connecting component 310.

[0118] One end of the coupling part 319 is connected to the main body part 316, and the other end of the coupling part 319 is not connected to the main body part 316. The coupling part 319 is configured to be inclined towards the direction close to the second surface 323 of the chip 320. Along the second direction, a part of the coupling part 319 and the projection of the second surface 323 at least partially overlap.

[0119] Referring to Figure 3 and Figure 8 As shown, an included angle θ is formed between the extending direction of the coupling part 319 and the plane where the main body part 316 is located, and 0 < θ < 90°. For example, the included angle θ can be 15°, 30°, 45°, or 60°, etc. Such a structure enables the coupling part 319 to have a certain elastic force in the first direction, which can improve the electrical connection effect between the coupling part 319 and the first contact pin 21 and enhance the connection stability.

[0120] In a possible implementation manner, referring to Figure 4 As shown, the second surface 323 has a second electrical contact part 324; the chip 320 has a center line L extending in the third direction, that is, the length direction of the center line L is parallel to the Z-axis. The center line L divides the chip 320 into a first region and a second region. The second electrical contact part 324 and part of the first electrical contact parts 321 are located in the first region, and the remaining first electrical contact parts 321 are located in the second region.

[0121] Referring to Figure 4 , Figure 5 and Figure 7 As shown, the second surface 323 also has an information contact 328, which is used for the programming tool to rewrite, upgrade, or record information to the chip 320, etc.

[0122] In the second direction, the second electrical contact portion 324 and a part of the first electrical contact portion 321 are located in the first region, and the notch 325 and the other part of the first electrical contact portion 321 are located in the second region. When the connecting member 310 and the chip 320 are in the installed state, a part of the connecting arm 313 abuts against the first electrical contact portion 321 located in the first region, and the other part of the connecting arm 313 abuts against the first electrical contact portion 321 located in the second region. It should be noted that by providing the first electrical contact portions 321 in the first region and the second region respectively, when the first electrical contact portion 321 in one of the first region and the second region fails, the first electrical contact portion 321 in the other region of the first region and the second region can still contact the inner contact portion 313b1 to ensure the normal communication between the chip 320 and the image forming apparatus.

[0123] In addition, by providing the first electrical contact portions 321 in the first region and the second region respectively, and the connecting arms 313 respectively abutting against the corresponding first electrical contact portions 321, it can be ensured that when the consumable cartridge is loaded into the image forming apparatus and the contact pin assembly contacts the second electrical contact portion 324 of the chip 320 and applies a force to the chip 320, the forces on the first region and the second region of the chip 320 are more balanced, avoiding the problem that due to the mismatch in the distribution of the number of contact points in the first region and the second region, the chip 320 is offset due to different forces exerted by the contact pins in different regions, resulting in poor contact or unstable contact between the second electrical contact portion 324 and the second contact pin 22.

[0124] In a possible implementation manner, referring to Figure 5 and Figure 7 As shown, there are at least two connecting arms 313; when the chip 320 is in the installed state, one of the at least two connecting arms 313 abuts against the first electrical contact portion 321 located in the first region, and the other of the at least two connecting arms 313 abuts against the first electrical contact portion 321 located in the second region. In this example, there are two connecting arms 313, one connecting arm 313 abuts against the first electrical contact portion 321 located in the first region, and the other connecting arm 313 abuts against the first electrical contact portion 321 located in the second region, realizing dual connection communication. Even if the communication of one of the connecting arms 313 fails, there is still the other connecting arm 313 that can realize communication to ensure the normal communication between the chip and the image forming apparatus.

[0125] In a possible implementation manner, referring to Figure 5 and Figure 7As shown, an avoidance hole 316a is provided in the main body portion 316. The chip 320 further includes a storage element 326, and the storage element 326 is disposed on the second surface 323 of the chip 320. Among them, the first surface 322 faces the connecting component 310, the second surface 323 faces away from the connecting component 310, the first surface 322 has a first electrical contact portion 321, and the second surface 323 has a second electrical contact portion 324. At least one of the first electrical contact portion 321 and the second electrical contact portion 324 is electrically connected to the storage element 326.

[0126] In a possible implementation manner, both the first electrical contact portion 321 and the second electrical contact portion 324 are electrically connected to the storage element 326; alternatively, one of the first electrical contact portion 321 and the second electrical contact portion 324 is electrically connected to the storage element 326, and the other is not electrically connected to the storage element 326; alternatively, a part of the first electrical contact portion 321 is electrically connected to the storage element 326, and another part of the first electrical contact portion 321 is not electrically connected to the storage element 326; alternatively, a part of the second electrical contact portion 324 is electrically connected to the storage element 326, and another part of the second electrical contact portion 324 is not electrically connected to the storage element 326.

[0127] In a possible implementation manner, the storage element 326 is located within the avoidance hole 316a, and the connecting arm 313 is located on the inner wall of the avoidance hole 316a.

[0128] When the chip 320 and the connecting component 310 are in the installed state, the avoidance hole 316a can form an avoidance for the storage element 326, avoiding the problem that the chip 320 and the connecting component 310 cannot be installed due to structural interference.

[0129] Reference Figure 5 and Figure 6 As shown, first positioning portions 113a are provided on the outer wall 113 of the placement portion 110 at intervals. The connecting component 310 has a second positioning portion 310a. When the connecting component 310 is installed with the placement portion 110 of the consumable cartridge, the first positioning portion 113a penetrates through the second positioning portion 310a of the connecting component 310.

[0130] In a possible implementation manner, the first positioning portion 113a can be a positioning post, the second positioning portion 310a is a positioning hole, the number of the first positioning portions 113a can be four, and in other possible implementation manners, the number of the first positioning portions 113a can also be multiple.

[0131] The chip 320 is further provided with a third positioning portion 327. When the chip 320 and the placement portion 110 are in the installed state, the first positioning portion 113a provided on the placement portion 110 penetrates through the third positioning portion 327 to achieve the effect of positioning the chip 320.

[0132] When the electrical connection component 300 is installed in the consumable cartridge, first assemble the connection component 310 with the placement portion 110, and then assemble the chip 320 with the connection component 310. It should be noted that if the connection component 310 is assembled with the chip 320 first, since the space between the chip 320 and the placement portion 110 is small, the electrical connection component 300 cannot be assembled with the placement portion 110. Therefore, the installation sequence of the connection component 310 and the chip 320 is: first assemble the connection component 310 with the placement portion 110, and then assemble the chip 320 with the connection component 310.

[0133] The present utility model further provides a consumable cartridge, which is detachably installed in an image forming apparatus. Refer to Figure 5 、 Figure 9 and Figure 10 As shown, when the connection component 310 is fixedly connected to the placement portion 110 of the main body 100, the first positioning portions 113a on the placement portion 110 respectively penetrate through the second positioning portion 310a of the connection component 310 and the third positioning portion 327 of the chip 320. By heating the first positioning portions 113a with an auxiliary tooling to form a welding portion (not shown in the figure), the chip 320 is fixedly installed with the placement portion 110, and the welding portion is used to prevent the chip 320 and the connection component 310 from disengaging from the placement portion 110.

[0134] It should be noted that in this embodiment, the number of the first positioning portions 113a is preferably four. In other possible implementation manners, the number of the first positioning portions 113a may also be multiple. The connection component 310 or the chip 320 can be assembled with the placement portion 110 by means of welding, pasting, abutting, snap connection, etc.

[0135] Refer to Figure 5 、 Figure 7 and Figure 10 As shown, when the electrical connection component 300 and the consumable cartridge are in an installed state, the first electrical contact portion 321 contacts the inner contact portion 313b1 on the connection arm 313, and a part of the storage element 326 enters the placement portion 110 through the clearance hole 316a, and a part of the coupling portion 319 is exposed through the notch 325.

[0136] Refer to Figure 3 、 Figure 4 and Figure 5 As shown, when the consumable cartridge and the installation unit 10 are in an installed state, the first contact pin 21 is electrically connected to the coupling portion 319, that is, the first electrical contact portion 321 is electrically connected to the first contact pin 21 through the connection component 310, and the second electrical contact portion 324 is electrically connected to the second contact pin 22.

[0137] In some examples, when the chip 320 includes a ground terminal, a power supply terminal, a reset terminal, a clock terminal, and a data terminal, the first electrical contact portion 321 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 electrical contact portion 324 includes the remaining contact portions other than the first electrical contact portion 321.

[0138] 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 through this terminal, power is provided for the operation of the storage element 326; the reset terminal is used to reset the internal data of the storage element 326; 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.

[0139] In other examples, when the chip 320 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 electrical contact portion 321 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 electrical contact portion 324 includes the remaining contact portions other than the first electrical contact portion 321. It should be noted that the high-voltage terminal is used to detect whether the consumable cartridge is correctly installed in the image forming apparatus. 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.

[0140] Reference Figure 3 、 Figure 5 and Figure 7 As shown in, the coupling portion 319 has an outer contact portion 319a electrically connected to the first contact pin 21. It should be noted that the coupling portion 319 is at least partially exposed through the notch 325 for realizing the electrical connection between the outer contact portion 319a and the first contact pin 21. By constructing one end of the coupling portion 319 to be inclined toward the chip 320, even when the board thickness of the chip 320 increases in the prior art, a stable electrical connection between the first contact pin 21 and the outer contact portion 319a can be ensured, and the problem of communication interruption between the chip 320 and the image forming apparatus caused by the coupling portion 319 being far from the second surface 323 of the chip 320 in the prior art can be avoided. For example, when the board thickness of the chip 320 is too large, the edge of the notch 325 will squeeze the first contact pin 21, causing the first contact pin 21 to be compressed in a direction away from the second surface 323 of the chip 320, and further resulting in the disconnection of the contact between the first contact pin 21 and the outer contact portion 319a and the communication interruption between the chip 320 and the image forming apparatus.

[0141] Embodiment 2

[0142] In the consumable cartridge provided in the second embodiment of the present utility model, the difference between the connecting component 310 and that in the first embodiment lies in that:

[0143] Referring to Figure 11 and Figure 12 As shown, the placement portion 110 has a center line M3, which is parallel to the X-axis. The placement portion 110 has a center line M3, which is parallel to the X-axis. Along the third direction, the placement portion 110 is divided by the center line M3 into an upper portion 116 and a lower portion 117.

[0144] In this embodiment, along the third direction, a plurality of first components 220 are arranged at intervals. The plurality of first components 220 include at least one upper component 224 and at least one lower component 225. The upper component 224 or the lower component 225 is located on the inner wall 112. In the third direction, that is, the Z-axis direction, the lower component 225 or the upper component 224 is arranged at intervals, that is, there is a gap S between the upper component 224 and the lower component 225.

[0145] In this embodiment, referring to Figure 12 and Figure 13 As shown, the connecting component 310 includes support arms 312. The number of support arms 312 is preferably two. The two support arms 312 are configured to be arranged at intervals in the third direction on the connecting component 310. The arrangement direction of the support arms 312 is adapted to the arrangement direction of the lower component 225 or the upper component 224 of the placement portion 110.

[0146] Referring to Figure 12 and Figure 13 As shown, the support arm 312 has a second surface 3121 and a third surface 3122. The second surfaces 3121 of the two support arms 312 face away from each other, and the third surfaces 3122 of the two support arms 312 face each other; both the second surface 3121 and the third surface 3122 have a second contact portion 311a. The cross-sectional dimension of the second region is configured as the distance between the second surface 3121 and the corresponding third surface 3122.

[0147] The size of the first region formed by the locking member 200 is less than or equal to the size of the second region formed by the second contact portion 311a, that is, in the second direction, the distance between at least one upper component 224 and at least one lower component 225 is less than or equal to the thickness of the support arm 312.

[0148] Referring to Figure 14 and Figure 15As shown, during the process of inserting the connecting component 310 into the placement portion 110, each locked component 311 is correspondingly inserted into the gap between at least one upper component 224 and at least one lower component 225, that is, the support arm 312 is gradually inserted into the gap S between at least one upper component 224 and at least one lower component 225. Therefore, the second contact portions 311a provided on the second surface 3121 and the third surface 3122 of the support arm 312 are in contact with the first contact portions 210 provided on the first surface 221 of the upper component 224 and the lower component 225.

[0149] Since in the third direction, the thickness of the support arm 312 is greater than or equal to the distance between the upper component 224 and the lower component 225, as the support arm 312 gradually enters the gap S, the tightening force received by the support arm 312 gradually increases. When the connecting component 310 is completely installed on the placement portion 110, the support arm 312 is completely accommodated in the gap S. At this time, the tightening force received by the support arm 312 is the largest, thereby realizing a tight fit between the support arm 312 and the upper component 224 and the lower component 225, that is, through the tight fit of each locked component 311 with the corresponding set of locking components 200, and then realizing the fixed installation of the connecting component 310 and the placement portion 110, avoiding the situation in the prior art where due to the offset of the installation position of the connecting component 310 or the damage of a part of the fixing structure of the connecting component 310, the first electrical contact portion 321 on the chip 320 is in misalignment or poor contact with the connecting component 310, or the problem that the connecting component 310 is easily directly detached from the consumable cartridge. For example, if the operator fails to notice that the connecting component 310 has fallen off the consumable cartridge and directly installs the chip 320, it will cause some terminals on the chip 320 to be not electrically connected to the corresponding communication connection of the contact pins in the image forming apparatus, resulting in the failure to realize some functions of the chip 320. This solution can improve the communication quality and stability between the chip 320 and the image forming apparatus.

[0150] In the second embodiment, the remaining structures of the consumable cartridge are the same as those in the first embodiment, and the communication method between the electrical connection component and the contact pin component is the same as that in the first embodiment, which will not be elaborated here.

[0151] Embodiment 3

[0152] In a consumable cartridge provided by the third embodiment of the present invention, the difference between the connecting component 310 and the first and second embodiments lies in:

[0153] Along the second direction and the third direction, a plurality of first components 220 are arranged at intervals.

[0154] Reference Figure 16 、 Figure 17 and Figure 18As shown, a plurality of first components 220 include a left component 222 and a right component 223. The left component 222 and the right component 223 are arranged at intervals in the second direction. The plurality of first components 220 further include an upper component 224 and a lower component 225. The upper component 224 and the lower component 225 are arranged at intervals in the third direction.

[0155] The connecting component 310 includes four support arms 312. Two support arms 312 are arranged at intervals in the second direction, and the other two support arms 312 are arranged at intervals in the third direction.

[0156] In this embodiment, the number of support arms 312 can be four.

[0157] Reference Figure 19 and Figure 20 As shown, when the connecting component 310 and the placement part 110 of the main body 100 are in an installed state, in the second direction, each arranged support arm 312 enters between a corresponding group of left component 222 and right component 223 and is in tight fit with them. In the third direction, each arranged support arm 312 enters between a corresponding group of lower component 225 and upper component 224 and is in tight fit with them, thereby realizing the fixed connection between the connecting component 310 and the placement part 110. This avoids the situation in the prior art where due to the offset of the installation position of the connecting component 310 or the damage of a part of the fixed structure of the connecting component 310, the first electrical contact part 321 on the chip 320 is in misalignment or poor contact with the connecting component 310, or the problem that the connecting component 310 is easily directly detached from the consumable cartridge, and improves the stability and communication quality of the electrical connection of the corresponding communication connection between the chip 320 and the contact pins in the image forming apparatus.

[0158] The remaining structures of the electrical connection assembly, the installation method of the connecting component and the placement part, and the communication method between the chip and the contact pin assembly are the same as those in Embodiment 1 or Embodiment 2, and will not be elaborated here.

[0159] Embodiment 4

[0160] The difference between this Embodiment 4 and Embodiment 1 is that, referring to Figure 21 、 Figure 22 and Figure 23 As shown, a plurality of groups of locking parts 200 are located on the outer wall 113 of the placement part 110. In the first direction, the outer wall 113 faces the connecting component 310.

[0161] In this embodiment, a plurality of groups of locking parts 200 are respectively arranged in the left part 114 and the right part 115. The locking part 200 includes a recessed part 250. In the first direction, the recessed part 250 is recessed in a direction away from the connecting component 310. The recessed part 250 has a first inner peripheral surface 230, and a first contact part 210 is formed on the first inner peripheral surface 230. The inner diameter of the recessed part 250 is the cross-sectional dimension of the first region.

[0162] In this embodiment, the shape of the recess 250 is a circular groove. The recess 250 has a first inner peripheral surface 230, and the first contact portion 210 is formed on the first inner peripheral surface 230.

[0163] The locked member 311 has a protruding portion 330 that protrudes from the main body portion 316 in the first direction. The protruding portion 330 has a first outer peripheral surface 3111, and the second contact portion 311a is formed on the first outer peripheral surface 3111. The outer diameter of the protruding portion 330 is the cross-sectional dimension of the second region. Here, the protruding portion 330 is a columnar structure protruding from the main body portion 316. For example, the protruding portion 330 may be a hollow cylindrical shape. The outer diameter of the protruding portion 330 is the dimension along the radial direction of the protruding portion 330.

[0164] In this embodiment, with reference to Figure 21 、 Figure 22 and Figure 23 As shown, each locked member 311 is respectively arranged on the first side portion 317 and the second side portion 318. Each locked member is configured to have a protruding portion 330 from the connecting member 310. The protruding portion 330 is located on the side of the connecting member 310 facing the placement portion 110. In this embodiment, the shape of the protruding portion 330 is cylindrical. The protruding portion 330 has a first outer peripheral surface 3111, and the second contact portion 311a is formed on the first outer peripheral surface 3111. The diameter of the protruding portion 330 is the cross-sectional dimension of the second region.

[0165] It should be noted that the size of the first region formed by the locking member 200 is less than or equal to the size of the second region formed by the second contact portion 311a. That is, in the second direction, the diameter of the recess 250 provided on the placement portion 110 is less than or equal to the diameter of the protruding portion 330 of the connecting member 310. Thus, when the connecting member 310 and the placement portion 110 are in the installed state, the protruding portion 330 enters the recess 250 and is in a tight fit with the recess 250, thereby realizing the fixed installation of the connecting member and the consumable cartridge.

[0166] In some embodiments, the recessed portions 250 respectively disposed on the left portion 114 and the right portion 115 of the placement portion 110 are at the same distance from the center line M1 of the placement portion 110 in the second direction. The protruding portions 330 respectively disposed on the first side portion 317 and the second side portion 318 of the connecting member 310 are at the same distance from the center line M2 of the connecting member 310 in the second direction. Furthermore, when the connecting member 310 and the placement portion 110 are in an installed state, the plane where the connecting member 310 is located is substantially parallel to the plane where the placement portion 110 is located, so that the forces received on both sides of the center line of the connecting member 310 are the same as the combined force of the installation of the placement portion 110, avoiding the problem that the connecting member 310 is tilted as a whole due to uneven forces in the left-right or up-down directions of the connecting member 310, and further causing the problem that the internal contact portion on the chip cannot be electrically connected to or has poor contact with the connecting member 310, improving the communication quality and stability between the chip and the printing device, reducing the failure rate during the use of the chip, and enhancing the safety of user use.

[0167] In addition, referring to Figure 21 , Figure 22 and Figure 24 shown, since multiple sets of locking members 200 are provided on the side of the placement portion 110 facing the connecting member 310, more space and selectivity are provided for the design of the structure, size, and position of the multiple sets of locking members 200. Since the plane where the multiple sets of locking members 200 are located is parallel to the plane where the locked member 311 is located, compared with the prior art where the plane of the clamping structure on the connecting member 310 and the plane of the clamping structure on the chip mounting position are arranged at an angle, the present application can greatly improve the precise positioning of the connecting member 310 and the placement portion 110 during the assembly process. At the same time, a tight fit connection is adopted between the two, which can avoid the problem that the connecting member 310 falls off the consumable cartridge due to external environment or human factors in the prior art, ensuring the information interaction and the realization of related functions between the chip and the printing device during subsequent use, and enhancing the user experience.

[0168] The remaining structures of the electrical connection component, the installation method of the connecting member and the placement portion, and the communication method between the chip and the contact pin component are the same as those in the first embodiment, and will not be elaborated here.

[0169] Embodiment Five

[0170] The difference between this Embodiment Five and Embodiment Four is that, referring to Figure 25 , Figure 26 , Figure 27 and Figure 28 shown, in this embodiment, the locking member 200 includes a protrusion 260. The protrusion 260 extends towards the connecting member 310 in the first direction. The protrusion 260 has a second outer peripheral surface 240, and a first contact portion 210 is formed on the second outer peripheral surface 240. The diameter of the protrusion 260 is the cross-sectional dimension of the first region;

[0171] A plurality of locking members 200 are located on the outer wall 113 of the placement portion 110. The plurality of locking members 200 are respectively arranged in the left portion 114 and the right portion 115. Each group of locking members 200 is configured as a protrusion 260 that protrudes in the first direction toward the connection portion 310. The protrusion 260 is cylindrical and has a second outer peripheral surface 240. A first contact portion 210 is formed on the second outer peripheral surface 240.

[0172] In the first direction, the locked member 311 is a hollow portion 340 formed in the main body portion 316. The hollow portion 340 has a second inner peripheral surface 3112. A second contact portion 311a is formed on the second inner peripheral surface 3112. The diameter of the hollow portion 340 is the cross-sectional dimension of the second region, that is, the inner diameter of the hollow portion 340 is the cross-sectional dimension of the second region.

[0173] In this embodiment, each locked member 311 is respectively arranged in the first side portion 317 and the second side portion 318. Each locked member is configured as a hollow portion 340 on the connecting member 310. In this embodiment, the shape of the hollow portion 340 is circular or elliptical. The hollow portion 340 has a second inner peripheral surface 3112. A second contact portion 311a is formed on the second inner peripheral surface 3112.

[0174] It should be noted that the size of the first region formed by the locking member 200 is greater than or equal to the size of the region formed by the second contact portion 311a. That is, in the second direction, the diameter of the protrusion 260 provided on the placement portion 110 is greater than or equal to the diameter of the hollow portion 340 of the connecting member 310. Furthermore, when the connecting member 310 and the placement portion 110 are in the installed state, the protrusion 260 enters the hollow portion 340 and is in a tight fit with the hollow portion 340, thereby realizing the fixed installation of the connecting member and the consumable cartridge.

[0175] The remaining structures of the electrical connection component and the communication method between the chip and the probe component are the same as those in Embodiment Four and will not be elaborated here.

[0176] Embodiment Six

[0177] The difference between this Embodiment Five and Embodiment Four lies in referring to Figure 29 , Figure 30 , Figure 31 and Figure 32 As shown, in this embodiment, the locking member 200 includes at least two protrusions 270. The protrusions 270 extend in a direction away from the connecting member 310. The protrusions 270 have opposite fifth surfaces 271 and sixth surfaces 272. Both the fifth surface 271 and the sixth surface 272 have a first contact portion 210. The distance between the fifth surface 271 and the sixth surface 272 is the cross-sectional dimension of the first region.

[0178] In this example, in the third direction, the fifth surface 271 and the sixth surface 272 are located on two outer wall surfaces of two pairs of the bump 270.

[0179] Multiple sets of locking members 200 are located on the outer wall 113 of the placement portion 110. Multiple sets of locking members 200 are respectively arranged in the left portion 114 and the right portion 115. Each set of locking members 200 is configured to face the bump 270 near the connecting portion 310 in the first direction. The bump 270 has a cuboid or cube structure. On the fifth surface 271 and the sixth surface 272 of the bump 270 that are arranged back to back in the third direction, the first contact portions 210 are respectively formed. The distance between the fifth surface 271 and the sixth surface 272 is the cross-sectional dimension of the first region.

[0180] The connecting member 310 includes at least one set of support plates 315. One set of support plates 315 includes two support plates 315. At least one set of support plates 315 is arranged at intervals on the main body portion 316. The support plate 315 includes a fourth surface 3151. The fourth surfaces 3151 of at least two support plates 315 arranged at intervals face each other; the distance between the fourth surfaces 3151 of at least two support plates 315 arranged at intervals is the cross-sectional dimension of the second region.

[0181] In this embodiment, each locking member 311 is respectively arranged on the first side portion 317 and the second side portion 318. Each locking member 311 is configured such that, in the third direction, multiple support plates 315 are arranged at intervals and adjacent to each other. Each support plate 315 extends in the first direction away from the connecting member 310. Each support plate 315 includes a fourth surface 3151. Multiple support plates 315 arranged at intervals have fourth surfaces 3151 that face each other. The second contact portions 311a are respectively formed on the fourth surfaces 3151. The distance between the fourth surfaces 3151 of two support plates 315 is the cross-sectional dimension of the second region.

[0182] It should be noted that the size of the first region formed by the locking member 200 is less than or equal to the size of the region formed by the second contact portion 311a, that is, the width of the bump 270 provided on the placement portion 110 in the second direction or the third direction is less than or equal to the distance between the fourth surfaces 3151 of adjacent support plates 315 of the connecting member 310. Furthermore, when the connecting member 310 and the placement portion 110 are in the installed state, the bump 270 enters between adjacent support plates 315 and is tightly fitted with the adjacent support plates 315, thereby realizing the fixed installation of the connecting member and the consumable cartridge.

[0183] Of course, in other examples, it is still possible that in the second direction, the fifth surface 271 and the sixth surface 272 are located on two outer wall surfaces of two pairs of the bump 270.

[0184] It should be noted that in this embodiment, the bump 270 can also be configured to have a fifth surface 271 and a sixth surface 272 that are arranged back to back in the second direction. Similarly, each locked member 311 is also configured to have a plurality of support plates 315 that are spaced apart and adjacent to each other in the second direction, for adapting to the direction in which the bump 270 is arranged.

[0185] The remaining structures of the electrical connection component and the communication method between the chip and the probe component are the same as those in the fourth embodiment, and will not be elaborated here.
