Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to an electrical connection component and a consumable box. Background Technology

[0002] Printers and other printing devices are common office equipment that provides convenience for modern offices. Printing devices contain replaceable consumable cartridges with electrical connection components that communicate with the printer's stylus pins.

[0003] In the prior art, the electrical connection component has multiple terminals. Due to factors such as the placement of the stylus in the printing device, the multiple terminals are arranged relatively dispersedly on the substrate of the electrical connection component. That is, the distance between some terminals and other terminals is far, which makes the size of the electrical connection component larger. This leads to an increase in the space on the consumable box to accommodate the electrical connection component, which increases the processing difficulty and causes unnecessary waste.

[0004] Furthermore, the existing electrical connection component structure is limited by the requirement that each terminal on the electrical connection component must make electrical contact with the corresponding pin in the printing device. This restricts the placement of each terminal on the substrate of the electrical connection component, reducing the design freedom, flexibility, and compatibility of the electrical connection component. In addition, if there are issues such as unstable pin installation in the printing device, accidental bending of the pins, friction damage to the contact points, or other problems, it can cause unstable or interrupted communication between the electrical connection component and the printing device, affecting the normal use of the consumable cartridge.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] A consumable cartridge is a component within an image forming apparatus that needs to be replaced frequently. The image forming apparatus can be an inkjet image forming apparatus, and the corresponding consumable cartridge is a cartridge that stores ink. Alternatively, the image forming apparatus can be a laser image forming apparatus, and the corresponding consumable cartridge is a processing cartridge, developing cartridge, or toner cartridge, etc., that stores toner.

[0028] The chip on the consumable box is used to store information such as manufacturer information, ink volume information, consumable box type information, ink color, related processing programs, and communication programs.

[0029] For a better explanation of the consumable box components, please refer to... Figure 4 , Figure 6 As shown, establish a coordinate system: define the width direction of the chip as the X-axis direction, the thickness direction of the chip as the Y-axis direction, and the length direction of the chip as the Z-axis direction, wherein the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0030] 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 angle between the first direction, the second direction, and the third direction can be 90°. In other possible implementations, the angle between the first direction and the second direction can be 80° to 200°, for example, 80°, 85°, 90°, 95°, or 200°.

[0031] The electrical connection components and consumable boxes provided in the embodiments of this utility model will be described in detail below with reference to specific examples.

[0032] Example 1 like Figure 1 As shown in this embodiment, the first direction is the length direction of the consumable box, which is also the direction for installing or removing the consumable box; the second direction is the width direction of the consumable box; and the third direction is the height direction of the consumable box.

[0033] See Figures 1 to 3As shown, this embodiment of the utility model provides a consumable cartridge 100 that can be detachably installed into a mounting unit 60 of a printing device. The printing device has at least one mounting unit 60 and one conductive unit 70. In this embodiment, each mounting unit 60 corresponds to one conductive unit 70. The conductive unit 70 is used to connect to the grounding circuit of the printing device and transmit a grounding signal. The consumable cartridge is detachably installed in the mounting unit 60. In this embodiment, the conductive unit 70 is configured as a first conductive element 71. When the mounting unit 60 of the consumable cartridge 100 is in the installed state, the first conductive element 71 is located on the upper side of the consumable cartridge 100 in the third direction.

[0034] The first conductive element 71 is preferably constructed as a conductive plate-like structure located on the upper side of the consumable box 100. The first conductive element 71 may also be constructed as other conductive structures to adapt to the mounting unit 60 of different printing devices.

[0035] Each mounting unit 60 is further provided with a contact pin assembly 61, which includes a first contact pin 611 and a second contact pin 612. The number of first contact pins 611 and second contact pins 612 can be one or more. In this embodiment, the second contact pin 612 is configured to include a grounding contact pin and a reset contact pin.

[0036] like Figures 4 to 7 As shown, the consumable box 100 also includes an electrical connection assembly 200, which includes a chip 210 and a connecting component 220. In the first direction, the projection of the second contact pin 612 does not overlap with that of the electrical connection assembly 200, thereby reducing the size of the chip 210 and facilitating the miniaturization of the chip 210.

[0037] Specifically, in the first direction, the positions of the terminals (first terminal 211a) of the chip 210 for electrical contact with the first contact pin 611 and the positions of the connecting component 220 for electrical contact with the conductive unit 70 are biased towards the position of the first contact pin 611, and do not overlap with the projection of the second contact pin 612. This allows the terminals on the chip 210 to be concentrated on the substrate, with closer distances between the terminals, reducing the size of the chip 210. It also reduces the space on the consumable box 100 for accommodating the electrical connection assembly 200, lowering the manufacturing difficulty.

[0038] In one possible embodiment, the second contact 612 may be configured to include at least one of a ground contact, a reset contact, a power contact, a clock contact, and a data contact, and the first contact 611 may include other functional contacts besides the functional contacts corresponding to the second contact 612.

[0039] In one possible embodiment, the second contact 612 may be configured to include at least one of a ground contact, a reset contact, a power contact, a clock contact, a data contact, a high voltage contact, or a short circuit detection contact, and the first contact 611 may include other functional contacts besides the functional contacts corresponding to the second contact 612.

[0040] like Figures 4 to 8 As shown, the consumable cartridge 100 includes a body 110 and a bottom shell 190. The body 110 is installed in the bottom shell 190. The body 110 is configured to include a connector portion 130 and an ink storage portion 140. The ink storage portion 140 is connected to the connector portion 130. The connector portion 130 is provided with an ink outlet portion 150. Printing media (such as ink, toner, etc.) stored in the ink storage portion 140 is supplied to the ink supply unit 62 in the printing device through the ink outlet portion 150. The connector portion 130 is provided with a first mounting position 131 and a second mounting position 132. When the consumable cartridge 100 and the mounting unit 60 are in the installed state, the first mounting position 131 is configured to face the stylus assembly 61, and the second mounting position 132 is configured to face the first conductive element 71. The first mounting position 131 is configured to be recessed in a first direction toward the connector portion 130, and the second mounting position 132 is configured to protrude in a third direction away from the connector portion 130. The first mounting position 131 is provided with a fixing part 1311. The consumable box 100 also includes a receiving part 120. The receiving part 120 has a fixed part 121 on the side facing the first mounting position 131. The receiving part 120 is assembled with the fixing part 1311 on the first mounting position 131 through the cooperation of the fixed part 121 with the fixing part 1311. The second mounting position 132 is also provided with a first receiving part 1321. Locking parts 1322 are also provided on the two opposite side walls of the first receiving part 1321. The receiving part 120 has a clearance part 122. The clearance part 122 is constructed to form a hollow structure facing the body 110 in a first direction.

[0041] like Figure 6 , Figure 9 and Figure 10 As shown, the electrical connection assembly 200 includes a chip 210. Along a first direction, the chip 210 has a first side 213 (the formed plane) and a second side 214. The chip 210 also includes a plurality of terminals 211, including a first terminal 211a, a second terminal 211b, and a storage element 212. The consumable cartridge 100 also has a third side 215, which is connected to the first side 213 and the second side 214.

[0042] In one possible embodiment, the first terminal 211a may be disposed on the first side 213 of the chip 210, the second terminal 211b may be disposed on the second side 214 or the third side 215 of the chip 210, and the storage element 212 may be disposed on the first side 213 or the second side 214 of the chip 210.

[0043] In one possible embodiment, the first terminal 211a, the second terminal 211b, and the storage element 212 may be disposed together on one of the first side 213, the second side 214, and the third side 215.

[0044] In one possible embodiment, at least one of the first terminal 211a and the second terminal 211b is in electrical contact with the storage element 212, or both the first terminal 211a and the second terminal 211b are in electrical contact with the storage element 212.

[0045] In one possible embodiment, in the first direction, the second terminal 211b located on the second side 214 of the chip 210 is configured to at least partially overlap with the projection of at least one first terminal 211a located on the first side 213 of the chip 210, thereby making the terminal arrangement on the chip 210 more compact, which is conducive to the miniaturization of the chip and reduces the processing difficulty of the chip 210.

[0046] In this embodiment, the number of terminals 211 is at least three, and the terminals 211 are configured to include at least a data terminal, a clock terminal, a ground terminal, and / or a power terminal.

[0047] Preferably, the first terminal 211a includes three terminals, such as... Figure 4-13 As shown, the first terminal 211a is configured to include a data terminal, a clock terminal, and a power terminal. This layout of the terminals makes the chip 210 smaller and facilitates its miniaturization. The first terminal 211a is located on the first side 213. The second terminal 211b is a ground terminal and is located on the second side 214. This further optimizes the terminal layout and improves the safety and reliability of the chip 210.

[0048] It should be noted that the chip 210 in this embodiment does not have a reset terminal. The reset function of the chip 210 is implemented by the reset circuit inside the storage element 212 in conjunction with the corresponding program.

[0049] In one possible embodiment, chip 210 does not have a power supply terminal. The power supply to chip 210 is achieved by using a reset terminal in conjunction with the conversion circuit inside the storage element 212 and the corresponding program.

[0050] In one possible embodiment, chip 210 does not have a ground terminal. Chip 210 achieves simulated grounding by configuring an external power supply or a time-division multiplexing terminal in conjunction with the buck circuit inside the storage element 212 and the corresponding program.

[0051] It should be noted that the reset function, grounding and power supply function of chip 210 can also be implemented in other ways in the embodiments of this application.

[0052] like Figure 6 As shown, the electrical connection assembly 200 further includes a connecting member 220, which includes a first portion and a second portion connected to each other. The first portion is used for electrical contact with the second terminal 211b, and the second portion is used for contact with the first conductive element 71 in the conductive unit 70. The first portion is configured to include an extension 221, which is received in a relief portion 122 on the receiving portion 120. The extension 221 has an inner contact end 221a, which is configured to protrude toward the second terminal 211b for electrical contact with it. The second portion includes a bending portion 222, a portion of which extends into the first receiving portion 1321 of the second mounting position 132. A locking portion 1322 located in the first receiving portion 1321 abuts against a portion of the bending portion 222 to prevent the bending portion 222 from dislodging from the first receiving portion 1321. Another part of the bent portion 222 is configured to protrude from the first receiving portion 1321 in a third direction. This part of the bent portion 222 has an outer contact portion 222a for contacting the first conductive member 71 in the conductive unit 70. The first conductive member 71 may be the top wall of the mounting unit 60, which is used to connect to the grounding unit in the printing device and is capable of transmitting a grounding signal. The outer contact portion 222a of the bent portion 222 can contact the top wall of the mounting unit 60. Furthermore, the second terminal 211b is electrically connected to the first conductive member 71 through the bent portion 222 of the connecting member 220 to receive the grounding signal.

[0053] Additionally, the connecting component 220 includes a joint 223 for connecting the extension 221 and the bend 222, respectively. The joint 223 is configured to extend from the receiving portion 120 toward the first receiving portion 1321, and the connector portion 130 is provided with a second receiving portion 133 for receiving a portion of the joint 223. The second mounting position 132 is provided with a support portion 1323 for supporting another portion of the joint 223.

[0054] like Figure 6 As shown, the portion between dashed line A and dashed line B is the extension 221 of the connecting member 220, the portion between dashed line B and dashed line C is the joint 223 of the connecting member 220, and the portion between dashed line C and dashed line D is the bending portion 222 of the connecting member 220.

[0055] In one possible embodiment, the connecting component 220 is entirely or at least partially made of a deformable material, such as the bending portion 222, which allows the bending portion 222 to make non-rigid contact with the conductive unit 70. Simultaneously, a contact force is applied to the conductive unit 70 during contact, effectively preventing poor contact or loss of contact between the connecting component 220 and the conductive unit 70 due to improper chip installation or external environmental factors such as vibration or shaking during use. This improves the communication quality and stability between the chip and the image forming apparatus. Because the bending portion 222 and the conductive unit 70 make non-rigid contact, it also prevents damage or irreversible deformation caused by stress generated during the instantaneous contact between the connecting component 220 or the bending portion 222 and the conductive unit 70 due to user-induced forceful installation or improper installation, thus extending the service life of the bending portion 222.

[0056] Positioning parts 123 are provided at intervals on the outer wall of the receiving part 120, and a positioning part 218 is provided on the chip 210. When the chip 210 and the receiving part 120 are in the installation state, the positioning part 218 is connected to the positioning part 123 provided on the receiving part 120 to achieve the effect of positioning the chip 210.

[0057] When the electrical connection assembly is installed in the consumable box, the connecting component 220 is first assembled with the connector 130, and then the chip 210 is assembled with the connecting component 220. It should be noted that if the connecting component 220 is assembled with the receiving part 120 before the chip 210, the space between the chip 210 and the receiving part 120 is too small, preventing the connecting component 220 from being assembled with the receiving part 120. Therefore, the installation sequence of the connecting component 220 and the chip 210 is to first assemble the connecting component 220 with the receiving part 120, and then assemble the chip 210 with the connecting component 220. It should be noted that in this embodiment, the number of positioning parts 123 is preferably four. In other possible implementations, the number of positioning parts 123 can also be multiple, and the number of positioned parts 218 is adapted to the number of positioning parts 123.

[0058] like Figures 11 to 14As shown, in one possible embodiment, when the consumable box 100 and the mounting unit 60 are in the mounting state, each first terminal 211a makes electrical contact with the corresponding first contact pin 611 to form a corresponding first contact point 10a, and the bent portion 222 makes electrical contact with the conductive unit 70 to form a corresponding second contact point 10b. In the plane where the first side 213 of the chip 210 where the first terminal 211a is located is located, a first virtual line M1 and a second virtual line M2 that are orthogonal to each other are defined respectively, and the second virtual line M2 extends toward the second direction; the first contact point 10a and the second contact point 10b are projected toward the second virtual line M2 to form a first projection point 10c and a second projection point 10d respectively; the first projection point 10c falls on the second virtual line M2, and the second projection point 10d falls outside the second virtual line M2, that is, the second projection point 10d falls on the third virtual line M3. In the plane where the first terminal 211a is located on the first side 213 of the chip 210, the first contact point 10a and the second contact point 10b are located on one side of the center of the contact pin assembly 61; the second contact pin 612 is located on the other side. Specifically, as shown... Figure 14 As shown, the stylus assembly 61 has a center line H. The first contact point 10a and the second contact point 10b on the first terminal 211a are located on one side of the center line H of the stylus assembly 61, and the second stylus 612 is located on the other side. The first projection point 10c and the second projection point 10d are located on one side of the center line H, and the second stylus 612 is located on the other side. The number of first contact points 10a located on both sides of the first virtual line M1 is the same (one for each); the number of first projection points 10c located on both sides of the first virtual line M1 is the same.

[0059] The first terminal 211a includes a data terminal, a clock terminal, and a power terminal, forming first contact points 10a, namely data terminal contact point 10a1, clock terminal contact point 10a2, and power terminal contact point 10a3. The data terminal contact points 10a1, clock terminal contact point 10a2, and power terminal contact point 10a3 are arranged in an alternating vertical arrangement. The data terminal contact point 10a1 is located on the first virtual line M1, while the clock terminal contact point 10a2 and power terminal contact point 10a3 are located on opposite sides of the first virtual line M1. The clock terminal contact point 10a2 is on one side of the first virtual line M1, and the power terminal contact point 10a3 is on the other side of the first virtual line M1. The clock terminal contact points 10a2 and power terminal contact points 10a3 are symmetrical relative to the first virtual line M1. The clock terminal contact points 10a2 and power terminal contact points 10a3 are symmetrical at their projection points on the second virtual line M2.

[0060] like Figure 13As shown, in one possible embodiment, when the consumable box 100 and the mounting unit 60 are in the mounting state, each first terminal 211a makes electrical contact with the corresponding first contact pin 611 to form a corresponding first contact point 10a, and the bent portion 222 makes electrical contact with the conductive unit 70 to form a corresponding second contact point 10b. In the plan view where the first contact point 10a and the second contact point 10b are located, a first virtual line M1 and a second virtual line M2 that are orthogonal to each other are defined respectively, and the second virtual line M2 extends toward a second direction; the first contact point 10a and the second contact point 10b are projected toward the direction of the second virtual line M2 to form a first projection point 10c and a second projection point 10d respectively, and the second projection point 10d located on the second virtual line M2 coincides with at least one first projection point 10c.

[0061] like Figure 12 and Figure 13 As shown, in one possible embodiment, among all the projection points on the second virtual line M2, the line connecting the two outermost projection points has a midpoint MP. The first virtual line M1 passes through the midpoint MP. Along the second direction, the chip 210 is divided into a first region 216 and a second region 217 by the first virtual line M1. The number of terminals or contact points arranged in the first region 216 and the second region 217 are the same.

[0062] In one possible implementation, the number of terminals, contact points, or projection points located on both sides of the first virtual line M1 are the same.

[0063] It should be noted that in this embodiment, the contact points include a first contact point 10a and a second contact point 10b.

[0064] The above terminal arrangement of the chip ensures that when the consumable cartridge is inserted into the printing device, the first contact pin 611 contacts the first terminal 211a of the chip 210 and applies force to the chip 210, so that the first region 216 and the second region 217 of the chip 210 are subjected to more balanced force. This avoids the problem of the chip 210 shifting due to the mismatch in the number of contacts in the first region 216 and the second region 217, which would cause the chip 210 to be subjected to different forces by the contact pin in different regions, resulting in poor contact or unstable contact between the first terminal 211a and the first contact pin 611.

[0065] Example 2 The difference between this second embodiment and the first embodiment is that, Figure 15 As shown, the first direction is the length of the consumable box, the second direction is the width of the consumable box, and the third direction is the height of the consumable box, which is also the direction for installing or removing the consumable box.

[0066] like Figure 16 and Figure 17As shown, in this second embodiment, the conductive unit 70 is constructed as a first conductive element 71. The first conductive element 71 is located outside the mounting unit 60; specifically, in the third direction, the first conductive element 71 is located on the upper side of the mounting unit 60. The structure of the consumable box 100 is as follows: Figure 16 , Figure 17 As shown, the structure differs from that of Embodiment 1, and the consumable box 100 does not have a receiving part 120. The ink storage part 140 is located inside the body 110 of the consumable box 100. Along the first direction, the body 110 has a first surface 160, and the first mounting position 131 is located on the first surface 160. The first surface 160 is also provided with a handle part 170. Along the third direction, the body 110 has a second surface 180, and the ink dispensing part 150 is located on the second surface 180 for supplying the printing media stored in the ink storage part 140 to the ink supply unit 62 in the printing device. Chip 210 is mounted on the first mounting position 131 of the consumable box 100. The extension 221 of the connecting member 220 is located in the first mounting position 131. The engaging portion 223 is attached to the first surface 160. The first surface 160 has a limiting portion 161 for abutting against the engaging portion 223 to prevent the connecting member 220 from falling off the consumable box 100. At the same time, the bent portion 222 at least partially abuts against the limiting portion 161 to support the bent portion 222 and prevent deformation. The bent portion 222 extends to the handle portion 170. The external contact portion 222a is located on the bent portion 222 at the position closest to the first conductive member 71 and makes electrical contact with the first conductive member 71. This allows the second terminal 211b of chip 210 to make electrical contact with the first conductive member 71 through the connecting member 220, enabling communication between chip 210 and the printing device.

[0067] In this embodiment, the positioning part 123 is disposed on the first mounting position 131, and the number of positioning parts 123 is adapted to the number of positioning parts 218 provided on the chip 210.

[0068] The first conductive element 71 is preferably constructed as a conductive rod-shaped structure, which is located on the upper side of the consumable box 100. The first conductive element 71 can also be constructed as other conductive structures to adapt to the mounting units 60 of different printing devices. In this embodiment, the first conductive element 71 is used to connect with the grounding unit in the printing device and can transmit a grounding signal.

[0069] In this embodiment, the connecting component 220 is preferably constructed as a sheet structure, and the first conductive component 71 can also be constructed as other conductive structures to adapt to the mounting unit 60 of different printing devices.

[0070] In this embodiment, the structure of the electrical connection component 200, the manner of electrical contact between the electrical connection component 200 and the mounting unit 60, and the relationship of their projection positions are the same as in Embodiment 1, and will not be repeated here.

[0071] Example 3 The difference between this embodiment three and embodiments one and two is that, for example Figures 18 to 20 As shown, the conductive unit 70 is configured as a second conductive element 72. The second conductive element 72 is located in the mounting unit 60 and spans across the mounting unit 60. Along the first direction, the second conductive element 72 is located behind the stylus assembly 61. The second conductive element 72 is provided with a plurality of conductive areas 723. Each mounting unit 60 corresponds to one conductive area 723, that is, each stylus assembly 61 corresponds to one conductive area 723. Each conductive area 723 has a plurality of conductive terminals. The plurality of conductive terminals are configured to include a first conductive terminal 721 and a second conductive terminal 722. The side of the first stylus 611 facing the second conductive element 72 is in electrical contact with the first conductive terminal 721, and the side of the second stylus 612 facing the second conductive element 72 is in electrical contact with the second conductive terminal 722.

[0072] like Figure 21 As shown, there is a gap S between the stylus assembly 61 and the second conductive member 72. At least a portion of the bent portion 222 enters between the stylus assembly 61 and the second conductive member 72 through the gap S and makes electrical contact with the first conductive terminal 721 in the corresponding conductive area 723.

[0073] In this embodiment, the bending portion 222 of the connecting component 220 is preferably configured to protrude from the outside of the consumable box 100 along a first direction, and in the first direction, the bending portion 222, the connecting portion 223 and the chip 210 enclose a space portion K. When the consumable box 100 and the printing device are in the installation state, the stylus assembly 61 is located in the space portion K.

[0074] It should be noted that in this embodiment, the first terminal 211a is configured to have two terminals, namely a data terminal and a power terminal, and the second terminal 211b is a clock terminal.

[0075] In one possible embodiment, the first terminal 211a may also be configured as a data terminal and a clock terminal, or a clock terminal and a power terminal.

[0076] It should be noted that the chip 210 in this embodiment may not have a reset terminal or / and a ground terminal. The reset function of the chip 210 can be implemented by the reset circuit inside the storage element 212 in conjunction with the corresponding program. The chip 210 can be simulated grounded by configuring an external power supply or a time-division multiplexing terminal in conjunction with the step-down circuit inside the storage element 212 in conjunction with the corresponding program.

[0077] In one possible embodiment, the number of connecting parts 220 may also be multiple.

[0078] In one possible embodiment, the first conductive terminal 721 is preferably configured as one or more of a data conductive terminal, a clock conductive terminal, and a power conductive terminal.

[0080] The structure of the remaining parts is the same as that of Embodiment 1 and Embodiment 2, and can bring the same or similar technical effects. They will not be described in detail here. For details, please refer to the description of the above embodiments.

[0081] In one possible embodiment, the first contact pin 611 has a first end and a second end. In a third direction, the second end is higher than the first end and is closer to the conductive unit 70 than the first end. The outer contact portion 222a of the bent portion 222 can also make electrical contact with the second end of the first contact pin 611.

[0082] like Figure 20 As shown, the second conductive member 72 is provided with a plurality of conductive dots 724. The conductive dots 724 are connected to the grounding unit in the printing device and can transmit grounding signals. When the electrical connection assembly 200 and the printing device are in the installation state, the outer contact portion 222a of the bent portion 222 of the connection member 220 is used to make electrical contact with the conductive dots 724.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
