Description

Technical Field

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

[0002] Printers are a common office device in modern offices. Taking inkjet printers as an example, they use built-in nozzles to spray liquid ink into tiny droplets that adhere to paper, thus completing the printing job. The consumable cartridge is an important component of an inkjet printer, primarily used to store printing ink so that the nozzles can perform continuous, uninterrupted printing. Common consumable cartridges include ink cartridges, ink bags, and toner cartridges, in addition to ink cartridges.

[0003] Existing ink cartridges typically contain a chip. Contacts on this chip are electrically connected to the printer's stylus assembly. During printer use, the cartridge communicates with the printer via this chip to identify the cartridge type, remaining ink level, and usage status, thus better controlling its operation. However, the two sets of contacts on the existing cartridge chip used for electrical connection to the stylus assembly are relatively close together, posing a risk of short circuits. Furthermore, the protruding contacts on the chip can loosen or even detach after prolonged use, significantly shortening the cartridge's lifespan.

[0004] Therefore, there is an urgent need to design a chip to solve the above-mentioned problems in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a consumable chip and consumable box that can reduce the risk of short circuit in the chip and improve safety in use.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Consumable chips, including:

[0008] substrate;

[0009] A first contact group and a second contact group are spaced apart on the substrate. The first contact group includes at least one contact piece protruding from the substrate, which is used to connect with a first contact recessed in the stylus assembly. The second contact group includes at least one contact point, which is used to connect with a second contact protruding from the stylus assembly.

[0010] A fastener is fixedly connected to the substrate, and the fastener presses against the contact piece in a direction perpendicular to the surface where the first contact group is located on the substrate.

[0011] Preferably, the contact piece includes a base and a piece body connected to each other. The base is fixedly connected to the substrate. The fastener has a mounting hole for the piece body to pass through. The fastener covers the base, and the end of the piece body extending out of the mounting hole is used to abut against the first contact.

[0012] Preferably, the consumable chip further includes a conductive sheet, one end of which is movably connected to the contact, and the other end of which is away from the contact and used to abut against the second contact.

[0013] The consumable box includes a mounting box and the aforementioned consumable chip. The substrate is mounted on the mounting box. The consumable chip further includes a conductive sheet. One end of the conductive sheet is movably connected to the contact point, and the other end of the conductive sheet extends out of the substrate and is used to abut against the second contact of the stylus assembly.

[0014] The mounting box has a mounting groove for accommodating the conductive sheet, and the mounting groove extends in the direction directly opposite to the contact point.

[0015] Preferably, the mounting groove has a shoulder on its sidewall and the conductive sheet has a protrusion. When the protrusion abuts against the shoulder along the mounting direction of the conductive sheet, the end of the conductive sheet abuts against the contact point.

[0016] Preferably, a clamping part is provided on the side wall of the mounting groove, and when the conductive sheet is placed in the mounting groove, the clamping part presses against the conductive sheet.

[0017] Preferably, the substrate is movably disposed on the mounting box along a first direction, which is the length direction of the conductive sheet.

[0018] Preferably, the mounting box is provided with an elastic element, and the position on the conductive sheet for abutting against the second contact is a second contact portion. The elastic element can apply an elastic force along the first direction to the substrate.

[0019] Preferably, the consumable box further includes a mounting bracket, which is slidably disposed on the mounting box body along the first direction, is connected to the elastic member, and the base plate is mounted on the mounting bracket.

[0020] Preferably, one of the mounting box and the substrate is provided with a limiting post, and the other is provided with a slot extending along the first direction.

[0021] The limiting post is inserted into the slot, and the position on the conductive sheet that connects to the contact point is a conductive contact portion. The conductive contact portion slides and abuts against the contact point along the first direction, and along the first direction, the length of the contact point is greater than or equal to the distance that the limiting post can move in the slot.

[0022] The beneficial effects of this utility model are as follows:

[0023] The consumable chip provided by this utility model includes a substrate, a first contact group, a second contact group, and fasteners. The first contact group includes multiple contact pieces protruding from the substrate, and the second contact group includes multiple contacts. The contact pieces and contacts respectively abut against the first and second contacts of the stylus assembly. Therefore, the consumable chip can be electrically connected to the stylus assembly, thereby realizing stable communication between the consumable chip and the printer. Since the first and second contact groups are spaced apart on the substrate, the first and second contact groups are assembled at intervals and with a large distance between them, which greatly reduces the risk of short circuit when the stylus assembly is electrically connected to the chip, and improves the safety of use. The fasteners are fixedly connected to the substrate. Since the fasteners press against the contact pieces along the installation direction of the contact pieces, the fasteners can fix the contact pieces, strengthen the connection between the contact pieces and the substrate, and further improve the stability and reliability of the contact pieces during use.

[0024] The consumable box provided by this utility model includes a mounting box and the aforementioned consumable chip. The consumable chip is electrically connected to the contact pin assembly through a conductive contact strip, which can avoid the contact wear problem caused by the consumable chip during use. Furthermore, since the conductive contact strip and the contact are movably connected, it greatly facilitates the maintenance and replacement by the staff, thereby greatly improving the practicality of the consumable box.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] like Figures 1 to 4As shown, this utility model provides a consumable chip for contacting and forming an electrical connection with the stylus mechanism of a printer. The stylus mechanism includes at least a first contact 110 recessed in the stylus assembly 100 and a second contact 120 protruding from the stylus assembly 100. The stylus assembly 100 is a cuboid structure with a groove on its end face along the length direction. The first contact 110 is embedded in the bottom of the groove, and the second contact 120 is elastically protruding from the end face of the stylus assembly 100 along the thickness direction near the consumable chip. The consumable chip includes a substrate 1, a first contact group, a second contact group, and a fastener 4. The substrate 1 is used to connect to the mounting housing 200. The first contact group and the second contact group are spaced apart on the substrate. In this embodiment, the first contact group and the second contact group are respectively disposed at both ends of the substrate 1. The first contact group includes at least one contact piece 2 protruding from the substrate 1. The contact piece 2 is used to connect with the first contact 110 recessed in the stylus assembly 100. The second contact group includes at least one contact 3. The contact 3 is used to connect with the second contact 120 protruding from the stylus assembly 100. The fastener 4 is fixedly connected to the substrate 1, and the fastener 4 presses against the contact piece 2 in a direction perpendicular to the substrate 1. Specifically, the substrate 1 has a first surface and a second surface. The first contact group is disposed on the first surface, and the fastener 4 presses against the contact piece 2 in a direction perpendicular to the first surface. In this embodiment, the contact piece 2 and the contact point 3 are respectively used to abut against the first contact 110 and the second contact 120 of the stylus assembly 100. Therefore, the consumable chip can be electrically connected to the printer through the stylus assembly 100, thereby realizing stable communication between the consumable chip and the printer. Since the first contact group and the second contact group are respectively disposed at both ends of the substrate 1, the first contact group and the second contact group are assembled at intervals and have a large distance between them, which greatly reduces the risk of short circuit when the stylus assembly 100 is electrically connected to the chip and improves the safety of use. The fastener 4 is fixedly connected to the substrate 1. Since the fastener 4 presses against the contact piece 2 in a direction perpendicular to the first surface, the fastener 4 can fix the contact piece 2, strengthen the connection between the contact piece 2 and the substrate 1, and further improve the stability and reliability of the contact piece 2 during use.

[0049] Specifically, to accommodate the stylus assembly 100 in this embodiment, the contact piece 2 is protruded and soldered onto the substrate 1, and the contact point 3 is formed on the surface of the substrate 1. In one embodiment, the first contact group includes four contact pieces 2, and the second contact group has five contacts 3. Electrical connection between the consumable chip and the stylus assembly 100 can only be achieved after the contact pieces 2 and contacts 3 have made contact with the first contact 110 and the second contact 120 of the stylus assembly 100. In other embodiments, the first contact group may include one contact piece 2, and the second contact group may have four contacts 3. This patent does not limit the number of contacts or contact pieces; the appropriate number of contacts or contact pieces can be set according to actual needs.

[0050] The specific structure of the fastener 4 and the cooperation method between the fastener 4 and the contact piece 2 can be set according to the actual situation; in this embodiment, such as Figure 3 As shown, the contact 2 includes a base 21 and a chip body 22 connected to each other. A conductive contact 12 is fixedly disposed on the substrate 1. The conductive contact 12 is connected to the memory (not shown) on the consumable chip. The base 21 is fixedly connected to the substrate 1 and electrically connected to the conductive contact 12. A mounting hole 41 is provided on the fastener 4 for the chip body 22 to pass through. The fastener 4 covers the base 21, and the end of the chip body 22 extending out of the mounting hole 41 abuts against the first contact 110. Specifically, the size of the mounting hole 41 matches the chip body 22. The fastener 4 is glued or welded to the substrate 1. The fastener 4 not only strengthens the connection between the contact 2 and the substrate 1, but also provides horizontal support for the chip body 22, thereby further extending the service life of the consumable chip. Generally, the memory is disposed on the second surface of the substrate 1, but it can also be disposed on the first surface or other positions according to actual needs.

[0051] like Figure 1 , Figure 2 The present invention also provides a consumable box, which includes a mounting box 200 and the aforementioned consumable chip. The mounting box 200 is used to contain ink. The substrate 1 is connected to the mounting box 200. The printer is electrically connected to the consumable chip through the stylus assembly 100, thereby realizing communication with the consumable box.

[0052] This utility model also provides an inkjet printer, which includes a stylus assembly 100 and the aforementioned consumable cartridge. The stylus assembly 100 is electrically connected to the consumable chip on the consumable cartridge, thereby enabling communication between the consumable chip and the printer. This allows the printer to identify the usage status of the consumable cartridge and the remaining ink level, thereby improving the practicality of the inkjet printer.

[0053] Example 1

[0054] like Figures 2 to 4 As shown, in this embodiment, in the first direction, the distance between the first contact 110 and the second contact 120 on the stylus assembly 100 is equal to the distance between the contact piece 2 and the contact point 3 on the substrate 1. Specifically, when the first contact 110 of the stylus assembly 100 abuts against the sheet 22 of the contact piece 2, the second contact 120 of the stylus assembly 100 abuts against the contact point 3, and the contact piece 2 and the contact point 3 on the substrate 1 are both disposed on the same surface. In other words, the position on the contact piece 2 that abuts against the first contact 110 is the first contact portion, and the position on the contact point 3 that abuts against the second contact 120 is the second contact portion. The distance between the first contact portion and the second contact portion in the first direction is equal to the distance between the first contact 110 and the second contact 120 on the stylus assembly 100 in the first direction.

[0055] In this embodiment, the substrate 1 is fixedly connected to the mounting box 200 of the consumable box. When the consumable box is installed in place, the sheet 22 of the contact piece 2 abuts against the first contact 110 of the contact pin assembly 100, and the contact 3 abuts against the second contact 120.

[0056] Example 2

[0057] like Figure 5 and Figure 6 As shown, this embodiment provides a consumable chip, which is basically the same as the consumable chip in Embodiment 1. The main difference is that the consumable chip also includes a conductive sheet 5. One end of the conductive sheet 5 is movably connected to the contact 3, and the other end of the conductive sheet 5 is away from the contact 3 and is used to abut against the second contact 120. In this embodiment, along the first direction, the distance between the first contact 110 and the second contact 120 on the contact pin assembly 100 is greater than the distance between the contact piece 2 and the contact point 3 on the substrate 1. The contact point 3 and the contact piece 2 are respectively disposed on two opposite end faces of the substrate 1, that is, the contact piece 2 is disposed on the first surface and the contact point 3 is disposed on the second surface. The contact point 3 abuts against the second contact 120 of the contact pin assembly 100 through the conductive sheet 5 and achieves electrical connection. Therefore, the wear problem of the contact point 3 caused by the consumable chip during use can be avoided. Furthermore, since the conductive sheet 5 and the contact point 3 are movably connected rather than welded or glued, it is convenient for the staff to replace and repair the conductive sheet 5, thereby greatly improving the practicality of the consumable chip. Specifically, the conductive sheet 5 is made of an elastic conductive metal sheet. The end near the contact point 3 is bent to form a conductive contact portion. The conductive contact portion abuts against the contact point 3. After the consumable chip and the conductive sheet 5 are stably installed, the conductive contact portion is pressed against the inside of the mounting groove and between the contact point 3 to ensure that the conductive sheet 5 and the contact point 3 form a stable installation relationship.

[0058] In other embodiments, the contact 3 and the contact piece 2 are respectively disposed on two opposite surfaces of the substrate 1, and the projections of the contact 3 and the contact piece 2 on the surface of the substrate 1 overlap by at least a portion. In this case, the length of the substrate 1 can be further reduced, thereby reducing the difficulty of fixing the chip and the manufacturing cost of the chip to a certain extent.

[0059] This embodiment also provides a consumable cartridge and an inkjet printer. The consumable cartridge is basically the same as that in Embodiment 1, with the main difference being that the mounting box 200 has a mounting groove 210 for accommodating the conductive sheet 5, and the mounting groove 210 extends in the direction directly opposite the contact point 3. Figure 7For example, the mounting groove 210 is recessed along the direction away from the contact point 3. In this embodiment, five mounting grooves 210 are formed on the surface of the mounting box 200 facing the substrate 1. The five mounting grooves 210 correspond one-to-one with the positions of the five contacts 3, and the mounting grooves 210 extend to the edge of the mounting box 200. Therefore, during installation, the mounting grooves 210 can position the conductive sheet 5, so that the conductive sheet 5 can accurately contact the contact point 3. In other words, the mounting groove 210 has at least two types of openings. The first type is an opening away from the first direction, which allows the conductive sheet 5 to be inserted into the mounting groove. The second type is an opening groove perpendicular to the first direction and away from the consumable box, which allows the stylus to enter the opening groove and contact the conductive sheet 5.

[0060] To better limit the position of the conductive sheet 5 and ensure good contact between the conductive sheet 5 and the contact 3, such as... Figure 7 As shown, a shoulder 211 is provided on the side wall of the mounting groove 210, and a protrusion is provided on the conductive sheet 5. When the protrusion abuts against the shoulder 211 along the mounting direction of the conductive sheet 5, the end of the conductive sheet 5 abuts against the contact point 3. In this embodiment, the conductive sheet 5 is inserted into the mounting groove 210 along the length direction of the mounting groove 210 through the opening groove to realize the assembly of the conductive sheet 5 and the substrate 1; along the first direction, the conductive sheet 5 includes a first segment 51 and a second segment 52. Both the first segment 51 and the second segment 52 are rectangular, and the width of the second segment 52 is greater than that of the first segment 52. After the two are coaxially connected, the wide side of the second segment 52 extends out of the first segment 51 at the connection to form a protrusion; correspondingly, the mounting groove 210 is divided into a first groove segment 213 and a second groove segment 214 along the length direction, wherein the width of the first groove segment 213 matches that of the first segment 51, and the width of the second segment 52 is greater than that of the first segment 51. The width of the second groove segment 214 matches that of the second segment 52, and the connection between the first groove segment 213 and the second groove segment 214 forms a concave groove shoulder 211. When installing the conductive sheet 5, the conductive sheet 5 needs to be inserted into the mounting groove 210 along the first direction, and the conductive sheet 5 is pushed to move in the mounting groove 210 until the protrusion of the conductive sheet 5 abuts against the groove shoulder 211 along the first direction. At this time, the conductive contact portion at the end of the conductive sheet 5 just abuts against the contact point 3 on the back of the substrate 1. Therefore, the cooperation between the groove shoulder 211 and the protrusion can play a positioning role in the installation of the conductive sheet 5, so as to ensure reliable contact between the conductive sheet 5 and the contact point 3.

[0061] Furthermore, such as Figure 7 As shown, a clamping part 212 is provided on the side wall of the mounting groove 210. When the conductive sheet 5 is disposed in the mounting groove 210, the clamping part 212 presses against the conductive sheet 5. In this embodiment, the clamping part 212 can press against the conductive sheet 5 in a direction perpendicular to the bottom surface of the mounting groove 210, preventing the conductive sheet 5 from coming out of the mounting groove 210, thereby improving the reliability of the electrical connection between the consumable chip and the contact pin assembly 100.

[0062] Example 3

[0063] like Figure 8 and Figure 9 As shown, this embodiment provides a consumable box, which is basically the same as the consumable box in Embodiment 2. The main difference is that the substrate 1 is movably disposed on the mounting box 200 along a first direction, which is the length direction of the conductive sheet 5. In this embodiment, the position on the sheet 22 that abuts against the first contact 110 is the first contact portion, and the position on the conductive sheet 5 that abuts against the second contact 120 is the second contact portion. Since the substrate 1 is movable along the first direction, the distance between the first contact portion and the second contact portion can be changed by moving the substrate 1, thereby greatly improving the adaptability of the consumable box to stylus assemblies 100 of different sizes.

[0064] Furthermore, such as Figure 9 As shown, an elastic element 300 is provided on the mounting box 200. The position on the conductive sheet 5 that abuts against the second contact 120 is the second contact portion. The elastic element 300 can apply an elastic force along the first direction to the substrate 1 so that the contact sheet 2 on the substrate 1 always abuts against the first contact 110.

[0065] In this embodiment, the elastic element 300 is a spring. The base plate 1 is movably disposed on the mounting box 200 along the first direction. The mounting box 200 is connected to the base plate 1 through the elastic element 300. Therefore, the base plate 1 can drive the contact piece 2 to move along the first direction and always abut against the first contact of the stylus assembly 100 under the elastic force of the elastic element 300. For example, when the distance between the first contact 110 and the second contact 120 on the stylus assembly 100 of the printer is large, the stylus assembly 100 can achieve the contact between the first contact 110 and the contact piece 2 by pushing the base plate 1 along the first direction, while ensuring good contact between the second contact 120 and the conductive sheet 5. This greatly improves the adaptability of the consumable box to stylus assemblies 100 of different sizes and ensures that the contact piece 2 always maintains close contact with the first contact 110. It is understandable that the position on the sheet 22 that abuts against the first contact 110 is the first contact portion, and the position on the conductive sheet 5 that abuts against the second contact 120 is the second contact portion. When the consumable box is not installed, along the first direction, the distance between the first contact portion and the second contact portion is less than or equal to the distance between the first contact portion and the second contact portion after the consumable box is installed, that is, less than the distance between the first contact 110 and the second contact 120.

[0066] To ensure good contact between conductive sheet 5 and contact 3, such as Figure 8 and Figure 9As shown, the mounting box 200 and the substrate 1 are provided, one with a limiting post 220 and the other with a slot 11 extending in the first direction; the limiting post 220 is inserted into the slot 11, and the position on the conductive sheet 5 that connects with the contact 3 is a conductive contact part, which slides and abuts against the contact 3 in the first direction, and the length of the contact 3 in the first direction is greater than or equal to the distance that the limiting post 220 can move in the slot 11. In this embodiment, the limiting post 220 is fixed on the mounting box 200, and the slot 11 is formed on the substrate 1. When the substrate 1 is assembled in place, the limiting post 220 passes through the slot 11. When the substrate 1 moves up and down along the first direction, the limiting post 220 will move relative to the substrate 1 in the slot 11 until it abuts against the upper or lower side wall of the slot 11. Within this range of movement, the contact 3 on the substrate 1 always maintains sliding friction contact with the conductive contact portion of the conductive sheet 5. When the consumable box is installed in place, the contact piece 2 abuts against the first contact 110.

[0067] The connection method between the substrate 1 and the mounting box 200 can be set according to the actual situation, as long as it ensures that the substrate 1 can move along the first direction and cooperate with the mounting box 200. In this embodiment, as shown... Figure 8 and Figure 9 As shown, the consumable box also includes a mounting bracket 400, which is slidably disposed on the mounting box body 200 along a first direction. The mounting box body 200 is provided with a mounting channel, and an elastic member 300 is disposed in the mounting channel, with one end connected to the mounting bracket 400 and the other end connected to the wall at the top of the mounting channel. The substrate 1 is fixedly connected to the mounting bracket 400. In another embodiment, in order to enhance the stability of the substrate 1 during movement, a sliding groove extending along the first direction is provided inside the mounting box body 200. A slide rail matching the sliding groove is provided on the end face of the mounting bracket 400 opposite to the substrate 1. The mounting bracket 400 is embedded in the sliding groove through the slide rail. The end of the elastic member 300 is connected to the mounting bracket 400, and the mounting bracket 400 is fixedly connected to the substrate 1.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
