Description

Technical Field

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

[0002] Consumable cartridges are typically equipped with a chip that communicates with the printer's contact pins to monitor the status of the consumables. The chip usually contains multiple contacts, and over time, conductive foreign matter, such as ink droplets, metal filaments, or metal scraps, can accumulate between these contacts. This foreign matter can cause short circuits, leading to chip damage or the printer failing to recognize the consumable cartridge.

[0003] To address the aforementioned issues, in related technologies, the target contact of the chip is located on the back side of the chip substrate, and a connector independent of the chip is added. This connector includes a first part and a second part interconnected. The first part is electrically connected to the target contact, and the second part at least partially overlaps the projection of a first sidewall at the edge of the chip. A pressing arm is positioned outside the chip mounting location on the consumable cartridge. When the consumable cartridge is installed in the printing device, the target pin, electrically connected to the target contact, enters between the pressing arm and the first sidewall of the chip. Under external force, the pressing arm applies pressure to the target pin, causing it to deform towards the second part of the connector. The target pin then contacts the second part of the connector, thereby enabling communication between the chip and the printing device.

[0004] However, in actual use, the force applied by the squeezing arm is difficult to control precisely, which can easily cause the chip to shift in the installation position on the consumable box. This can lead to poor contact or disconnection between the second contact pin and the second contact part, or misalignment of the contacts, resulting in short circuits or even terminal deformation, thus affecting the performance. Utility Model Content

[0005] This utility model provides a consumable box to solve the technical problem that the installation position of the chip on the consumable box is easily misaligned, affecting the stability of the electrical connection between the second contact pin and the second contact part.

[0006] To achieve the above objectives, this utility model provides a consumable box, detachably disposed in a printing device along the installation direction. The printing device includes a stylus assembly, the stylus assembly including at least two first styluses, and the consumable box includes:

[0007] The box body includes a main body and a receiving portion disposed on the outer wall of the main body;

[0008] A chip is disposed on the receiving portion. The chip includes a substrate and first contacts disposed on the substrate. The number of first contacts is the same on both sides of the center line of the substrate.

[0009] A connector for electrically connecting the first contact and the corresponding first contact pin, the connector comprising a first part and a second part connected to each other, the first part abutting against the first contact, and the second part abutting against the first contact pin to form a first contact portion;

[0010] At least two sets of auxiliary components are disposed on the receiving portion and located on opposite sides of the chip, the auxiliary components corresponding to the first contact pin and the second portion;

[0011] During the installation process of the consumable box and the printing device, the auxiliary component is configured to move the second part closer to the corresponding first contact pin to cause displacement or deformation, so that the second part abuts against the corresponding first contact pin, and the two sets of auxiliary components apply forces to the two second parts in opposite directions to balance the force on the chip;

[0012] The auxiliary component blocks the first contact portion formed by the second part and the first stylus making electrical contact.

[0013] This utility model provides a consumable box that, by setting two sets of auxiliary components located on opposite sides of the chip, applies opposite forces to the two second parts, making the forces acting on the two sides of the chip nearly balanced, thus preventing chip displacement. This fundamentally avoids the problem of poor contact, disconnection, or misalignment between the second contact pin and the second contact part caused by chip positional displacement, thereby preventing short circuits and significantly enhancing the continuity and stability of signal transmission, thereby improving the communication quality between the chip and the printing device.

[0014] In one possible implementation, with the consumable cartridge and the printing device in an installed state, at least a portion of the second part extends between the chip and the auxiliary component, and the first stylus extends between the side of the chip and the second part.

[0015] In one possible implementation, the auxiliary component includes a placement portion, which is a recessed structure formed into the interior of the auxiliary component, the placement portion having an opening facing the chip, and the second portion extending into the placement portion.

[0016] In one possible implementation, a first imaginary line is defined to extend along the width direction of the box body;

[0017] The chip further includes a second contact, and the contact pin assembly further includes a second contact pin. The second contact pin contacts a plurality of second contacts to form a second contact portion. The second contact portion is projected along the mounting direction onto a first imaginary line to form a projection point. The perpendicular bisector between the two projection points that are furthest apart is defined as a second imaginary line. One side of the second imaginary line is a first region, and the other side of the second imaginary line is a second region. The number of projection points is the same in the first region and the second region.

[0018] The second imaginary line is parallel to the center line of the substrate, and the extension direction of the second imaginary line is orthogonal to the extension direction of the first imaginary line.

[0019] In one possible implementation, the first part includes at least a connecting portion connected to the second part;

[0020] The receiving part includes a stabilizing part and a stopping part. The side of the receiving part facing away from the box body is the receiving surface. The stabilizing part is disposed on the receiving surface and abuts against the connecting part. The stopping part is connected to the stabilizing part, and a first anti-detachment groove is formed between the stopping part and the receiving surface. The connecting part extends into the first anti-detachment groove, and the stopping part abuts against the connecting part.

[0021] In one possible implementation, the second portion includes a bend and an extension, the bend connecting the first portion and the extension;

[0022] When the consumable cartridge and the printing device are installed, at least a portion of the structure of the extension is located on the same side of the corresponding first stylus as the corresponding auxiliary component, and the second portion is further away from the chip than the first stylus.

[0023] In one possible implementation, the placement portion has a protrusion, the extension abuts against the protrusion, and the protrusion is configured to apply a force to the extension under external force, so that the extension deforms toward the direction of the first stylus and abuts against the first stylus.

[0024] In one possible implementation, the auxiliary component further includes a shielding portion located on the side wall of the placement portion away from the receiving surface, the shielding portion abutting against the first stylus and shielding the first contact portion.

[0025] In one possible implementation, the box body and the receiving part are an integrally connected structure; or...

[0026] The outer wall of the box body has a receiving cavity, the receiving cavity is provided with a locking part, the receiving part is provided with a locked part, and the locking part is used to lock with the locked part.

[0027] In one possible implementation, the number of connectors is two;

[0028] The two connectors are arranged at intervals along the mounting direction, and the second portions of the two connectors are respectively located on opposite sides of the chip; or,

[0029] The two connectors are arranged at intervals along a direction perpendicular to the mounting direction, and the second portions of the two connectors are respectively located on opposite sides of the chip.

[0030] In one possible implementation, the box body further includes a support portion disposed on the outer wall surface of the box body;

[0031] The support portion includes a support portion and a folding portion connected to each other. One end of the support portion is connected to the box body, and the other end of the support portion is connected to the folding portion. A positioning groove is provided in the support portion, and part of the folding portion extends into the positioning groove. The extension portion abuts against the folding portion and extends toward the first stylus.

[0032] The stylus assembly also includes a stylus holder with multiple stylus slots. When the consumable box and the printing device are in the installed state, the extension extends into the corresponding stylus slot and abuts against the corresponding first stylus.

[0033] This utility model provides a consumable box. Since the auxiliary component and the second part are located on the same side of the first contact pin, the displacement stroke of the auxiliary component can be significantly shortened, thereby reducing the force required to be applied to the auxiliary component. Because the force applied to the auxiliary component is reduced, the deformation of the first contact pin is effectively controlled. This helps prevent the first contact pin from accidentally crossing over to the chip surface due to excessive deformation. It also effectively avoids deformation failure, fatigue damage, or bending failure of the first contact pin caused by maintaining a large deformation for a long time. This ensures the contact stability between the second part and the first contact pin, thereby improving the communication quality between the chip and the printing device, and ensuring that the printing device can accurately read and process the chip's information.

[0034] Furthermore, the reduced force applied to the auxiliary component lowers the operational difficulty and enhances the tolerance for force deviations. Even with some deviation in the force applied to the auxiliary component, the electrical connection between the second part and the first stylus will not significantly affect the normal operation of the printing equipment. This reduces the precision required to control the magnitude of the force applied to the auxiliary component, enhances operational simplicity, and reduces processing complexity.

[0145] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions 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.

[0146] Consumable cartridges are a part of a printing device that needs to be replaced frequently. The printing device can be an inkjet printer, and the corresponding consumable cartridge is an ink cartridge that stores ink. The printing device can also be a laser printer, and the corresponding consumable cartridges are processing cartridges, developing cartridges, toner cartridges, etc. that store toner.

[0147] Consumable cartridges typically contain a chip that stores information such as manufacturer details, ink level, cartridge type, and ink color. To prevent short circuits caused by charged foreign objects falling onto the chip, some contacts are located on the back surface of the chip, while the remaining contacts are located on the front surface. This reduces the likelihood of short circuits caused by charged foreign objects falling onto the chip.

[0148] In chip design, target contacts are positioned on the back of the chip substrate, and a connector independent of the chip is introduced. This connector is constructed to include a first portion for electrical connection to internal terminals on the chip, and a second portion for electrical connection to the stylus of the printing device. Along the thickness direction of the chip, the second portion at least partially overlaps with the projection of the first sidewall of the chip. A pressing arm is positioned outside the chip mounting position of the consumable cartridge. When the consumable cartridge is loaded into the printing process, the target stylus enters between the pressing arm and the first sidewall of the chip, i.e., between the target stylus and the second portion of the outer component of the cartridge and the pressing arm. Under external force, the pressing arm deforms the target stylus towards the second portion, causing the target stylus to contact the second portion, thereby enabling communication between the chip and the printing device.

[0149] Normally, the target stylus deforms under pressure from the extrusion arm to enhance electrical contact between the target stylus and the second part. However, if the external force applied to the extrusion arm is not precisely controlled, a series of problems can occur. For example, if the applied force is too large, the target stylus may extend directly over the top surface of the chip, preventing it from contacting the second part. Conversely, if the applied force is too small, the target stylus will not deform sufficiently, also resulting in ineffective contact with the second part of the connector, or poor contact. These situations can cause communication barriers between the chip and the printer, or prevent certain functions of the chip from operating properly, thus affecting the normal use of the chip.

[0150] During the use of the consumable box, the target pin may deform due to prolonged pressure from the compression arm. Similarly, the second part of the connector may also deform due to continuous pressure from the target pin. Because these components maintain significant deformation over extended periods, problems such as deformation failure, damage, or accidental bending of the target pin or the second part of the connector may occur. This situation leads to unstable electrical contact between the target pin and the second part of the connector, and the pressure from the compression arm is transmitted to the chip through the target pin and the second part of the connector, easily causing chip displacement. This can result in poor contact, loss of contact, misalignment, short circuits, or even terminal deformation between the second pin and the second contact point, affecting the performance.

[0151] In view of this, the consumable box provided by this utility model provides two sets of auxiliary components, which are respectively located on opposite sides of the chip. The two sets of auxiliary components apply forces to the two second parts in opposite directions, so that the forces on both sides of the chip are close to a balanced state, thereby preventing the chip from shifting. This fundamentally avoids the problem of poor contact, disconnection, or misalignment between the second contact pin and the second contact part caused by the chip's positional displacement, thus preventing short circuits and other problems. It significantly enhances the continuity and stability of signal transmission, thereby improving the communication quality between the chip and the printing device.

[0152] The consumable box provided in the embodiments of this utility model is described below with reference to the accompanying drawings.

[0153] Example 1

[0154] refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a consumable box, including a box body 10. The consumable box is detachably disposed in a printing device along the installation direction. The printing device includes a stylus assembly 50, which includes at least two first stylus 51.

[0155] refer to Figure 4 As shown, in order to better illustrate the consumable box, a coordinate system is established: the width direction of the box 10 is the X-axis direction, the height direction of the box 10 is the Y-axis direction, and the length direction of the box 10 is the Z-axis direction. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0156] refer to Figure 6 , Figure 7 and Figure 8 As shown, this embodiment of the utility model provides a consumable box, which also includes a chip 20, a connector 30, and at least two sets of auxiliary components 40. (Refer to...) Figure 4 , Figure 5 and Figure 6As shown, the housing 10 includes a housing body 18 and a receiving portion 11 disposed on the outer wall of the housing body 18, and the chip 20 is disposed on the receiving portion 11. Referring to Figure 9, the chip 20 includes a substrate 21 and first contacts 22 disposed on the substrate 21. The number of first contacts 22 is the same on both sides of the center line C1 of the substrate 21.

[0157] It should be noted that there can be multiple first contacts 22, and the number of connectors 30 is the same as the number of first contacts 22. The first contacts 22 can be configured to perform the same function or to perform different functions. In this embodiment, there are two first contacts 22, which are used as contacts to perform different functions.

[0158] refer to Figure 10 , Figure 11 and Figure 12 As shown, the connector 30 is used to electrically connect the first contact 22 and the corresponding first contact pin 51. The connector 30 includes a first part 31 and a second part 32 that are connected to each other. The first part 31 abuts against the first contact 22, and the second part 32 abuts against the first contact pin 51 to form a first contact portion.

[0159] refer to Figure 11 and Figure 13 As shown, the auxiliary components 40 are all disposed on the receiving portion 11 and are located on opposite sides of the chip 20, respectively. The auxiliary components 40 correspond to the first contact pin 51 and the second portion 32; Reference Figure 3 and Figure 8 As shown, during the installation process of the consumable box and the printing device, the auxiliary component 40 is configured to drive the corresponding second part 32 to move or deform closer to the corresponding first contact pin 51, so that the corresponding second part 32 abuts against the corresponding first contact pin 51, and the two sets of auxiliary components 40 apply forces to the two second parts 32 in opposite directions to balance the force on the chip 20. The auxiliary component 40 blocks the first contact portion formed by the electrical contact between the second part 32 and the first contact pin 51.

[0160] refer to Figure 8 As shown, the auxiliary component 40 located on the left side (-X axis side) applies force to the second part 32 located on the -X axis side in the +X axis direction, while the auxiliary component 40 located on the right side (+X axis side) applies force to the second part 32 located on the +X axis side in the -X axis direction. This results in the second parts 32 of the two connectors 30 pressing the first contact pin 51 and transmitting the force to the chip 20 in opposite directions, with magnitudes that are nearly the same or identical, thereby balancing the force on the chip 20.

[0161] The consumable box provided by this utility model has two sets of auxiliary components 40, which are respectively located on opposite sides of the chip 20. The two sets of auxiliary components 40 exert opposite forces on the two second parts 32, so that the forces exerted on both sides of the chip 20 by the second parts 32 are close to the equilibrium state. This prevents the chip 20 from being displaced, which could lead to problems such as poor contact, loss of contact, or misalignment between the second contact pin and the second contact part, causing short circuits. This improves the communication quality between the chip 20 and the printing device.

[0162] refer to Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the number of first contacts 22 is the same on both sides of the center line C1 of the substrate 21. When the connector 30 is arranged to electrically connect the first contacts 22 and the corresponding first pins 51, the number of second parts 32 of the corresponding connector 30 is the same on both sides of the center line C1 of the substrate 21. This makes the force transmitted from the auxiliary component 40 to both sides of the chip 20 through the first pins 51 and the second part 32 more balanced. This helps to solve the offset problem caused by uneven force on the chip 20, ensures that the force on both sides of the center line C1 of the chip 20 is more balanced, avoids the chip 20 from being offset in the mounting position on the housing 10, and makes the contact force between the second contact of the chip 20 and the second pin of the printing device more balanced. This avoids the situation where the contact force is insufficient, resulting in poor contact, loss of contact, or misalignment causing a short circuit, or the contact force is too large, resulting in wear or scratches on the terminal surface, or even deformation of the terminal. This ensures the communication quality between the chip 20 and the printing device.

[0163] refer to Figure 8 , Figure 13 and Figure 14 As shown, the auxiliary component 40 blocks the first contact portion formed by the electrical contact between the second part 32 and the first contact pin 51, which can solve the problem that foreign objects can easily adhere to the second part 32, the first contact pin 51 or other first contacts 22 of the chip 20, causing short circuits, burnout of the chip 20 or the printer not recognizing the device, thereby reducing the failure rate of the chip 20 during use, ensuring stable communication quality between the consumable box and the printer, and improving the safety of use.

[0164] In this first embodiment, reference is made to Figure 10 , Figure 11 and Figure 14As shown, there are two connectors 30, which can be arranged at intervals along the installation direction, i.e., along the Y-axis. Correspondingly, there are two first contact pins 51. There are two sets of auxiliary components 40, with one auxiliary component 40 in each set. The second parts 32 of the two connectors 30 are located on opposite sides of the chip 20, ensuring that the forces exerted by the two sets of auxiliary components 40 on the two connectors 30 are nearly balanced. This ensures that the chip 20 experiences uniform force during use, reducing problems such as displacement and poor electrical contact caused by unbalanced force on the chip 20.

[0165] In one possible implementation method, refer to Figure 1 and Figure 3 As shown, the stylus assembly 50 also includes a stylus holder 53 and a plurality of second stylus 52. The stylus holder 53 has a plurality of stylus slots, and the first stylus 51 and each of the second stylus 52 are respectively located in the corresponding stylus slots.

[0166] In one possible implementation, the printing device includes a mounting bracket 60 that can hold one or more consumable cartridges. The mounting bracket 60 has one or more receiving positions 61 for accommodating the consumable cartridges, each receiving position 61 having a stylus assembly 50. For example, the mounting bracket 60 may have four receiving positions 61, allowing it to hold four consumable cartridges that can store four different colors of ink or toner, such as black, yellow, blue, and red.

[0167] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the accommodating position 61 is also provided with a support member 62. The support member 62 is located on both sides of the stylus holder 53. The support member 62 includes two sets of alignment parts 621. When the consumable box and the printing device are in the installation state, the two sets of alignment parts 621 respectively abut against the two sets of auxiliary parts 40 and apply force towards the auxiliary parts 40, so that the auxiliary parts 40 deform towards the direction of the first stylus 51.

[0168] The accommodating position 61 is also provided with a main control circuit board (not shown in the figure). There is a gap between the inner wall of the accommodating position 61 and the stylus holder 53. The ends of the first stylus 51 and each second stylus 52 facing away from the chip 20 are electrically connected to the main control circuit board.

[0169] This embodiment of the invention provides a consumable cartridge where a first contact pin 51 is located between a chip 20 and a second part 32, such that an auxiliary component 40 and the second part 32 are located on the same side of the first contact pin 51. During the installation process of the consumable cartridge and the printing device, two sets of alignment parts 621 apply forces to the two sets of auxiliary components 40 respectively. The auxiliary components 40 are displaced towards the first contact pin 51 and apply forces to the second part 32, forcing the second part 32 to deform towards the first contact pin 51, thereby achieving electrical contact between the second part 32 and the first contact pin 51. In this example, the first contact pin 51 is the target contact pin, and the first contact point 22 is the target contact point.

[0170] Since the auxiliary component 40 and the second part 32 are located on the same side of the first contact pin 51, compared with the existing structure where the auxiliary component 40 and the second part 32 are located on opposite sides of the first contact pin 51, and the extrusion arm extrudes the target contact pin to cause a large deformation and make electrical contact with the second part of the external component, this application can significantly shorten the displacement stroke of the auxiliary component 40. Therefore, the force applied to the auxiliary component 40 needs to be reduced, which can reduce the deformation amplitude of the first contact pin 51. This helps to prevent the first contact pin 51 from accidentally crossing over to the upper surface of the chip 20. It can also effectively avoid the first contact pin 51 from deforming, failing, or accidentally bending due to maintaining a large deformation for a long time. This ensures the contact stability between the second part 32 and the first contact pin 51, thereby improving the communication quality between the chip 20 and the printing device, and ensuring that the printing device can accurately read and process the information of the chip 20.

[0171] In addition, the force required to be applied to the auxiliary component 40 is reduced, which lowers the difficulty of operation. Even if there is a certain deviation in the force applied to the auxiliary component 40, it will not significantly affect the normal operation of the printing equipment. This reduces the precision requirement for controlling the magnitude of the force applied to the auxiliary component 40, enhances the ease of operation, and reduces the complexity of processing.

[0172] In one possible implementation method, refer to Figure 10 and Figure 11 As shown, a first imaginary line L1 is defined to extend along the width direction of the cartridge 10. The chip 20 also includes a plurality of second contacts 24 disposed on the substrate 21, the second contacts 24 and the first contacts 22 being located on opposite sides of the substrate 21 respectively. When the consumable cartridge is in a fully installed state in the printing device, the second part 32 makes electrical contact with the first stylus 51 to form a first contact portion, the first contact portion being shielded by the auxiliary member 40, and the second contacts 24 make electrical contact with the second stylus 52 to form a second contact portion 241. In the plan view where the second contact portion 241 is located, the first imaginary line L1 and the second imaginary line L2 are defined to be orthogonal to each other, and the first imaginary line L1 extends along the width direction of the cartridge 10.

[0173] The second contact portion 241 is projected onto the first imaginary line L1 along the mounting direction to form a projection point. The perpendicular bisector between the two projection points furthest apart is defined as the second imaginary line L2. One side of the second imaginary line L2 is the first region, and the other side is the second region. The number of projection points is the same in both the first and second regions. The second imaginary line L2 is parallel to the center line of the substrate 21, and the extension direction of the second imaginary line L2 is orthogonal to the extension direction of the first imaginary line L1.

[0174] In this example, the projection points formed by the second contact portion projecting onto the first imaginary line L1 along the mounting direction are T1 and T2, respectively. The perpendicular bisector between the two farthest projection points T1 and T2 is the second imaginary line L2, which passes through the center point between projection points T1 and T2 on the first imaginary line L1. By symmetrically arranging the second contacts 24, the forces on the first and second regions can be more balanced, avoiding the problem of chip 20 shifting due to the different forces exerted by the contact pins on the first and second regions caused by the inconsistent distribution of the number of second contacts 24 in the first and second regions. This prevents problems such as poor contact, loss of contact, or short circuit caused by misalignment between the second contact pin and the second contact portion.

[0175] The second contact 24 and the first contact 22 are located on opposite sides of the substrate 21. That is, in the plan view where the multiple second contacts 24 are located, the first contact 22 is not visible, or the first contact portion is not visible, or the first contact 22 has no projection point on the first imaginary line L1.

[0176] In the first embodiment of this utility model, by symmetrically arranging the first contact portion formed by the electrical contact between the second part 32 and the first contact pin 51 on both sides of the chip 20, the force on the first region and the second region located on both sides of the second imaginary line L2 can be more balanced. This avoids the problem that the chip 20 is shifted due to the mismatch in the number distribution of the first contact portions in the first region and the second region, which would cause the chip 20 to be subjected to different forces by the contact pins and result in poor or unstable contact between the second contact pin 52 and the second contact point 24.

[0177] This chip structure can reduce the size of the chip 20, which is conducive to the miniaturization of the chip 20 and facilitates the production and processing of the chip 20. At the same time, it can also improve the flexibility of the arrangement of the second contact 24 and the first contact 22 on the substrate 21, so that users can change the arrangement position of the second contact 24 and the first contact 22 according to the stylus arrangement characteristics of different printing equipment, thereby improving the adaptability of the chip 20.

[0178] In one possible implementation method, refer to Figure 9 , Figure 10 and Figure 11As shown, the chip 20 also includes a storage element 23. The substrate 21 has a front surface 213 facing away from the housing 10 and a rear surface 214 opposite to the front surface 213. A second contact 24 is disposed on the front surface 213. The storage element 23 and the first contact 22 are disposed on the rear surface 214. At least one of the first contact 22 and the second contact 24 is electrically connected to the storage element 23, or each of the first contact 22 and the second contact 24 is electrically connected to the storage element 23. The second contact 24 is used to make electrical contact with the second contact pin 52.

[0179] The storage element 23 can be used to store data information such as ink capacity, chip authentication, and communication, as well as related processing programs and communication programs.

[0180] In one possible implementation, there may be multiple second contacts 24, which may be arranged in at least one row or at least one column on the front surface 213 of the substrate 21. The second pin 52 is electrically connected to the corresponding second contact 24.

[0181] In one possible implementation, along the thickness direction of chip 20, i.e., the Z-axis direction, the projection of one or more of the second contacts 24 at least partially overlaps with the projection of the first contact 22. This helps optimize space utilization, reduces the overall size of the substrate 21 of chip 20, and saves material costs on the substrate 21.

[0182] In one possible implementation, the first portion 31 makes electrical contact with the first contact portion 221 to form an inner contact point, and the second contact 24 makes electrical contact with the second contact pin 52 to form an outer contact point. Along the length direction of the consumable box, i.e., along the Z-axis direction, the projections of one or more of the inner and outer contact points at least partially overlap. Such a structure helps to optimize space utilization.

[0183] In one possible implementation, when chip 20 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, and a data terminal, the first contact 22 can be one or more of the ground terminal, power terminal, reset terminal, clock terminal, and data terminal. The second contact 24 includes the remaining contacts besides the first contact 22. In some examples, the first contact 22 has short-circuit detection and consumable box installation detection functions.

[0184] In some examples, when chip 20 includes a ground terminal, a power terminal, a reset terminal, a clock terminal, a data terminal, a high-voltage terminal, and a short-circuit detection terminal, the first contact 22 can be one or more of the following: ground terminal, power terminal, reset terminal, clock terminal, data terminal, high-voltage terminal, and short-circuit detection terminal. The second contact 24 includes the remaining contacts besides the first contact 22.

[0185] It should be noted that the grounding 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 provides power for the operation of the storage element 23 through this terminal; the reset terminal is used to reset the internal data of the storage element 23; the clock terminal is used to receive the clock signal; the data terminal is used to send or receive data signals, and is also used to detect a short circuit between the data terminal and at least one of the clock terminal, reset terminal, and power supply terminal.

[0186] In one possible implementation method, refer to Figure 4 and Figure 5 As shown, the cartridge body 18 has a storage cavity for storing toner or ink inside, and an ink outlet 182 at the bottom of the cartridge body 18. The toner or ink stored in the cartridge body 18 flows out from the ink outlet 182 and is supplied to the printing device.

[0187] refer to Figure 5 , Figure 6 and Figure 10 As shown, the receiving part 11 also includes a positioning post 16, and a positioning hole 211 is also provided in the substrate 21. The positioning post 16 extends into the positioning hole 211, thereby realizing the positioning and assembly effect of the chip 20.

[0188] refer to Figure 6 and Figure 9 As shown, there can be two or more positioning holes 211. The positioning holes 211 can be located on the upper and lower edges of the substrate 21. The number of positioning posts 16 is the same as the number of positioning holes 211, and their positions correspond to each other. There can be two or more positioning posts 16.

[0189] refer to Figure 13 and Figure 14 As shown, the outer wall of the box body 10 is also provided with a handle 17. The handle 17 can be connected to the outer wall surface of the box body 18. The handle 17 and the chip 20 are located on the same side wall of the box body 10. The side of the handle 17 facing away from the box body 10 is provided with a latching protrusion 171. During the process of installing the consumable box into the printing device, the latching protrusion 171 is used to elastically engage with the printing device, which facilitates the fixed installation of the consumable box.

[0190] In one possible implementation method, refer to Figure 10 and Figure 11 As shown, the substrate 21 of the chip 20 has a notch 212 facing the side of the two sets of auxiliary components 40, and the first contact pin 51 extends into the notch 212.

[0191] In one possible implementation method, refer to Figure 8 , Figure 10 and Figure 11As shown, with the consumable cartridge and printing device in the installed state, at least a portion of the second part 32 extends between the chip 20 and the auxiliary component 40, and the first contact pin 51 extends between the side of the chip 20 and the second part 32. This ensures that, with the consumable cartridge and printing device in the installed state, at least a portion of the second part 32 and the auxiliary component 40 are located on the same side as the first contact pin 51, and both the second part 32 and the auxiliary component 40 are further away from the chip 20 than the first contact pin 51. This significantly shortens the displacement stroke of the auxiliary component 40, thus reducing the force required on the auxiliary component 40, reducing the deformation of the first contact pin 51, and improving the overall durability and reliability of the structure.

[0192] In one possible implementation method, refer to Figure 5 , Figure 13 and Figure 14 As shown, the auxiliary component 40 includes a mounting portion 41, which is a recessed structure formed into the interior of the auxiliary component 40. The mounting portion 41 has an opening facing the chip 20, and a second portion 32 extends into the mounting portion 41. An extension portion 322 enters into the mounting portion 41 through the opening. The mounting portion 41 can accommodate the extension portion 322 and provide a certain degree of protection for the extension portion 322.

[0193] In one possible implementation method, refer to Figure 13 , Figure 14 and Figure 17 As shown, the first part 31 includes at least a connecting part 312, which is connected to the second part 32; the side of the receiving part 11 facing away from the box body 18 is the receiving surface 111.

[0194] In one possible implementation, the first portion 31 further includes a base end portion 311, with a connecting portion 312 connecting the base end portion 311 and the second portion 32. (See reference) Figure 5 , Figure 12 , Figure 14 and Figure 17 As shown, the receiving part 11 also includes a receiving part 15, in which a receiving groove is formed, and the base end part 311 extends into the receiving groove of the receiving part 15.

[0195] A fixing post 151 is provided within the receiving portion 15. The fixing post 151 is located within the receiving groove. One end of the fixing post 151 is connected to the receiving surface 111. A fixing cavity 3111 is formed within the base end portion 311, which can be fitted onto the outer peripheral surface of the fixing post 151. By fitting the fixing cavity 3111 onto the outer peripheral surface of the fixing post 151, the first part 31 of the connector 30 is connected to the housing 10. When the second part 32 of the connector 30 is subjected to the squeezing force of the auxiliary member 40, the problem of the connector 30 coming off is prevented.

[0196] In one possible implementation, the base end 311 can be made of metal wire, such as copper wire, spirally wound to form a ring-shaped columnar structure, with a fixing cavity 3111 formed at the center of the base end 311. The base end 311 can also be constructed in other ways to adapt to different connectors 30 or consumable boxes.

[0197] In one possible implementation, the connector 30 is a single piece formed by bending a metal wire. The connector 30 can also be configured in other ways to adapt to different consumable boxes.

[0198] In this embodiment, the extension 322 can be a protruding structure that protrudes along the length direction of the box 10, that is, along the -Z axis, in a direction away from the box 10.

[0199] In one possible implementation method, refer to Figure 5 , Figure 12 , Figure 14 and Figure 17 As shown, the receiving part 11 includes a stabilizing part 12 and a stopping part 13. The stabilizing part 12 is disposed on the receiving surface 111 and abuts against the connecting part 312. The stopping part 13 is connected to the stabilizing part 12, and a first anti-detachment groove 131 is formed between the stopping part 13 and the receiving surface 111. The connecting part 312 extends into the first anti-detachment groove 131, and the stopping part 13 and the connecting part 312 abut against each other.

[0200] In one possible implementation, the stabilizing part 12 can be a protruding structure that protrudes from the receiving part 11. The stabilizing part 12 can prevent the connecting part 312 from moving along the height direction of the box 10, i.e., the Y-axis direction, thereby increasing the stability of the connecting part 312.

[0201] In one possible implementation, there may be two stabilizing parts 12, which may be arranged at intervals along the height direction of the box body 10, i.e., the Y-axis direction. The connecting part 312 abuts against the two stabilizing parts 12, which helps to prevent the connecting part 312 from detaching from the receiving part 11 and improves the stability of the connecting part 312.

[0202] In one possible implementation, the stop portion 13 can prevent the connecting portion 312 from moving along the length direction of the housing 10, i.e., the Z-axis direction, reducing the problem of the connector 30 becoming loose or falling off due to vibration or external force. By restricting the movement of the connecting portion 312, the stability of the entire connector 30 is enhanced, ensuring the stability and reliability of the communication between the connector 30 and the chip 20 and the first contact pin 51.

[0203] In one possible implementation, the stop portion 13 can be a protruding structure that protrudes from the stabilizing portion 12 along the height direction of the housing 10, i.e., the Y-axis direction.

[0204] In one possible implementation, the second portion 32 includes a bend 321 and an extension 322, the bend 321 being connected between the first portion 31 and the extension 322; when the consumable cartridge and the printing device are in the installed state, at least a portion of the structure of the extension 322 is located on the same side of the first stylus 51 as the corresponding auxiliary component 40, and the second portion 32 is further away from the chip 20 than the first stylus 51.

[0205] This structure allows for reference during the installation process of the consumable box and the printing equipment. Figure 5 , Figure 10 , Figure 11 and Figure 12 As shown, the first contact pin 51 extends between the second part 32 and the chip 20. Under the action of external force, the auxiliary component 40 causes the second part 32 to deform and achieve contact electrical connection with the first contact pin 51. This can reduce the deformation of the first contact pin 51, which not only prevents the first contact pin 51 from coming off and sliding to the front surface 213 of the chip 20, but also prevents the first contact pin 51 from deforming over a long period of time, causing deformation failure, damage, or accidental bending, etc. This ensures the stability of the contact electrical connection between the second part 32 and the first contact pin 51 and improves the communication stability between the chip 20 and the printing device.

[0206] By setting the bending part 321, the extension direction of the extension part 322 is at an angle to the extension direction of the connecting part 312, which is beneficial for the extension part 322 to undergo elastic deformation after being squeezed.

[0207] In one possible implementation, a protrusion 411 is provided in the placement part 41, and the extension 322 abuts against the protrusion 411. The protrusion 411 is configured to apply a force to the extension 322 under the action of an external force, so that the extension 322 deforms toward the direction close to the first stylus 51 and abuts against the first stylus 51.

[0208] In one possible implementation, the protrusion 411 is a raised structure protruding from the mounting portion 41, such as a protruding ridge protruding from the inner wall surface of the mounting portion 41. By abutting against the protrusion 411, when the auxiliary member 40 is subjected to external force, the protrusion 411 can effectively transmit the force to the extension 322, thereby causing the extension 322 to displace or deform, which helps ensure the effectiveness of force transmission and the reliability of electrical contact.

[0209] In one possible implementation, the protrusion 411 may be in the shape of a straight line or a cross, and the edge of the protrusion 411 is connected to the inner wall of the mounting portion 41, so that the protrusion 411 can stably contact the extension portion 322.

[0210] In one possible implementation method, refer to Figure 5 , Figure 10 , Figure 12 and Figure 14 As shown, the auxiliary component 40 also includes a shielding portion 42, which is located on the side wall of the mounting portion 41 away from the receiving surface 111. The shielding portion 42 abuts against the first contact pin 51 and shields the first contact portion formed by the electrical contact between the second portion 32 and the first contact pin 51. The shielding portion 42 shields the abutting position between the second portion 32 and the first contact pin 51, that is, the first contact portion formed by the electrical contact between the extension portion 322 and the first contact pin 51 is shielded by the shielding portion 42. The shielding portion 42 serves to protect the abutting position between the second portion 32 and the first contact pin 51, ensuring that the electrical contact area between the second portion 32 and the first contact pin 51 is not affected by the external environment, such as dust, impurities, or other factors that may cause poor contact, thus ensuring the stability and reliability of the electrical connection.

[0211] In this example, the shielding part 42 is located on the side wall of the placement part 41 away from the receiving surface 111, that is, the shielding part 42 is located on the side wall of the placement part 41 along the -Z axis direction.

[0212] In one possible implementation, the extension 322 contacts the first contact pin 51 to form an outer contact 3221, which is used to contact the first contact pin 51. The projection of the outer contact 3221 along the length of the consumable box falls within the projection range of the shielding portion 42. This structure ensures that, along the length of the box 10 (Z-axis), the shielding portion 42 effectively blocks the contact between the outer contact 3221 of the extension 322 and the first contact pin 51, preventing dust, impurities, or other external factors from interfering with the contact between them. This effectively protects the contact between the outer contact 3221 and the first contact pin 51, ensuring the stability and reliability of the electrical connection. It also prevents foreign objects from adhering to the second part 32, the first contact pin 51, or between the second part 32 and the second contact 24, which could cause communication failures, short circuits, chip burnout, printer malfunction, or damage to the second part 32. This reduces the failure rate of the chip 20 during use and improves safety.

[0213] In one possible implementation method, refer to Figure 14 , Figure 15 and Figure 16 As shown, the receiving part 11 also includes a stop part 14, which is disposed on the side of the stabilizing part 12 facing the auxiliary member 40. A second anti-detachment groove 141 is formed between the stop part 14 and the auxiliary member 40. The bending part 321 extends into the second anti-detachment groove 141. The bending part 321 is configured to deform under the action of external force so that the two sides of the bending part 321 abut against the stop part 14 and the protrusion 411 respectively.

[0214] The stop part 14 provides additional fixing and restriction for the bent part 321. Through the joint blocking effect of the stop part 14 and the auxiliary part 40, the bent part 321 is ensured to be restricted within the second anti-detachment groove 141, and the position of the bent part 321 is better fixed, preventing the bent part 321 from loosening due to vibration and other factors, thereby improving the stability and reliability of communication between the connector 30 and the chip 20 and the first contact pin 51.

[0215] During the process of inserting the consumable cartridge into the receiving position 61 of the printing device, at least a portion of the auxiliary component 40 abuts against the alignment portion 621 in the receiving position 61. The action exerted by the alignment portion 621 on the auxiliary component 40 forces the auxiliary component 40 to move or deform towards the corresponding first stylus 51. When the bending portion 321 can stably abut against the stop portion 14, the second portion 32 is kept within a certain deformation range. This prevents the second portion 32 of the connector 30 from failing to make stable electrical contact with the first stylus 51 due to excessive deformation or displacement, and also prevents the first stylus 51 from being maintained in an excessively deformed state for a long time, which could cause the second portion 32 of the connector 30 to deform and fail, resulting in damage.

[0216] refer to Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary component 40 also includes a force-receiving part 43, which is located on the side of the auxiliary component 40 opposite to the receiving part 11. The force-receiving part 43 is used to receive the force from inside the printing device.

[0217] In one possible implementation, the force-receiving part 43 can be a protruding structure that protrudes from the auxiliary member 40 along the X-axis direction. By setting the force-receiving part 43, it is convenient for the force inside the printing device to be transmitted to the auxiliary member 40, so that the auxiliary member 40 causes the second part 32 of the chip 20 to deform or displace.

[0218] refer to Figure 1 , Figure 3 and Figure 5 As shown, during the process of the consumable cartridge being inserted into the receiving position 61 of the printing device, the first stylus 51 moves to the space between the second part 32 of the connector 30 and the chip 20. The alignment part 621 in the receiving position 61 of the printing device abuts against the force-receiving part 43 of the auxiliary member 40 and applies abutting force in the X-axis direction to the force-receiving part 43. This abutting force is applied to the second part 32 of the connector 30 through the auxiliary member 40. The second part 32 of the connector 30 deforms due to the squeezing action of the auxiliary member 40, so that the extension 322 of the second part 32 contacts the first stylus 51 to achieve electrical connection.

[0219] When the consumable cartridge is fully inserted into the receiving position 61, the shielding part 42 shields the position where the outer contact 3221 of the extension 322 contacts the first contact pin 51. This solves the problem of foreign objects easily adhering to the extension 322, the first contact pin 51, or other first contacts 22 of the chip 20, causing short circuits, burnout of the chip 20, or printer malfunction, thereby reducing the failure rate of the chip during use, ensuring stable communication quality between the consumable cartridge and the printer, and improving the safety of use.

[0220] In some examples, along the length direction of the consumable box, i.e. the Z-axis direction, the force-bearing part 43 is arranged on a different surface of the auxiliary part 40 than the shielding part 42. That is, along the Z-axis direction, the force-bearing part 43 is closer to the consumable box than the shielding part 42. A recess is formed between the force-bearing part 43 and the body of the auxiliary part 40, thereby achieving the purpose of improving the mechanical strength of the auxiliary part 40 and avoiding damage to the auxiliary part 40.

[0221] In one possible implementation, the box body 18 and the receiving part 11 are integrally connected as a single structure. This integral structure can be achieved through various manufacturing methods, such as injection molding or other suitable processes. By designing the box body 18 and the receiving part 11 as an integrally connected structure, assembly steps can be reduced, thereby improving the overall structural strength and durability.

[0222] In one possible implementation, the auxiliary component 40 can be an integral structure formed directly with the receiving part 11. Alternatively, it can be detachably connected to the receiving part 11. For example, the auxiliary component 40 can be connected to the receiving part 11 by screws, bolts, or the like.

[0223] In the first embodiment of this utility model, since the auxiliary component 40 and the second part 32 of the connector 30 are located on the same side of the first stylus 51, this application can significantly shorten the displacement stroke of the auxiliary component 40. Therefore, the force applied to the auxiliary component 40 is reduced. The force applied by the auxiliary component 40 to the first stylus 51 through the second part 32 is smaller, and the first stylus 51 will not undergo large deformation. This can effectively avoid the situation where the first stylus 51 is deformed, damaged, or accidentally bent due to the first stylus 51 maintaining a large deformation for a long time, thus ensuring the information interaction and related functions between the chip 20 and the printing device.

[0224] In the first embodiment of this utility model, the second part 32 of the connector 30 is configured such that when at least part of it deforms, it can abut against the stop part 13 provided on the stabilizing part 12, so that the second part 32 of the connector 30 is maintained within a certain deformation range. This avoids the second part 32 of the connector 30 from failing to make stable electrical contact with the first contact pin 51 due to excessive deformation or displacement, and avoids the second part 32 of the connector 30 from failing due to deformation and being damaged due to prolonged excessive deformation.

[0225] In one possible embodiment, the two fixing posts 151 may be distributed at diagonal positions on the bearing surface 111, that is, the two fixing posts 151 are arranged diagonally. Since the base ends 311 of the two connectors 30 are sleeved on the fixing posts 151, it can be understood that the base ends 311 of the two connectors 30 are arranged diagonally. This structural arrangement can distribute the load more evenly when subjected to external mechanical forces, such as instantaneous vibration and impact, and avoid the problem of deformation or breakage of connectors 30 due to excessive stress on one side or in a localized manner.

[0226] Example 2

[0227] The difference between this second embodiment and the first embodiment is that, referring to... Figure 18 and Figure 19 As shown, the box body 18 and the receiving part 11 are detachably connected.

[0228] In one possible implementation method, refer to Figure 19 , Figure 20 and Figure 21 As shown, the outer wall of the box body 18 has a receiving cavity 181, and the receiving part 11 is located inside the receiving cavity 181. The inner wall of the receiving cavity 181 is provided with a locking part 1811, and the side wall of the receiving part 11 is provided with a locked part 112, which is used to lock with the locking part 1811. This ensures that the receiving part 11 and the box body 18 remain firmly connected during use. At the same time, the receiving part 11 is modularly designed, allowing for necessary disassembly and maintenance in case of damage to the box body 18 or the receiving part 11, without the need for complete disposal.

[0229] The locking part 1811 and the locked part 112 can be designed in various ways, such as through the engagement of protrusions and grooves, or through the engagement of screws, bolts, and threaded holes, to achieve a reliable connection. This locking design ensures the stability of the receiving part 11 within the receiving cavity 181, preventing the receiving part 11 from loosening or falling off. It also allows for quick assembly and disassembly of the receiving part 11, facilitating maintenance and replacement.

[0230] In one possible implementation, locking portions 1811 are provided on both inner walls of the receiving cavity 181 along the Y-axis direction. The positions of the locked portions 112 correspond to the positions of the locking portions 1811, and the number is the same. This facilitates the stable installation of the receiving portion 11 into the receiving cavity 181 through the mutual cooperation of the locking portions 1811 and the locked portions 112.

[0231] For example, the locking portion 1811 may be a groove, and the locked portion 112 may be a protrusion.

[0232] In one possible implementation, the receiving cavity 181 can be a rectangular cavity or an elliptical cavity, and the shape of the receiving portion 11 is adapted to the shape of the receiving cavity 181.

[0233] In this second embodiment, the box body 18 and the receiving part 11 are detachably connected. If either the box body 18 or the receiving part 11 fails, it can be easily disassembled and replaced without replacing the entire device, saving costs. Furthermore, during the replacement of consumable boxes, users can replace different box bodies 18 or receiving parts 11 as needed to adapt to different functions or uses.

[0234] refer to Figure 21 , Figure 22 and Figure 23 As shown, the two fixing posts 151 can be distributed diagonally on the receiving surface 111, so that the second parts 32 of the two connectors 30 are located on opposite sides of the chip 20, so that the force exerted by the two sets of auxiliary parts 40 on the two connectors 30 is nearly balanced, and the force on both sides of the chip 20 is nearly balanced, ensuring that the chip is subjected to uniform force during use, and reducing problems such as displacement and poor electrical contact caused by unbalanced force on the chip 20.

[0235] In this embodiment, reference Figure 24 As shown, the number of first contacts 22 is the same on both sides of the center line C1 of the substrate 21, and the first contacts 22 are asymmetrically distributed on both sides of the center line C1 of the substrate 21. The base ends 311 of the two connectors 30 respectively abut against the two first contacts 22.

[0236] The remaining structure of this second embodiment is the same as that of the first embodiment, and will not be described again here.

[0237] Example 3

[0238] The difference between this embodiment three and embodiment one is that in this embodiment three, reference... Figure 25 , Figure 26 and Figure 27 As shown, there are two connectors 30, two corresponding first contact pins 51, and two sets of auxiliary parts 40, with one auxiliary part 40 in each set.

[0239] The two connectors 30 are arranged at intervals in a direction perpendicular to the installation direction, that is, the two connectors 30 are arranged at intervals along the X-axis and along the Y-axis. The center of each of the two connectors 30 is equidistant from the ink outlet 182. (Refer to...) Figure 32 As shown, with this structure, the dimensions of each connector 30 along the X-axis can be reduced, which can shorten the length of the connecting portion 312 of the first part 31, thus reducing the size of the connector 30 and saving material costs for the connector 30.

[0240] Correspondingly, the receiving part 11 includes two receiving parts 15, which are arranged at intervals along the X-axis direction. Receiving grooves are formed in the receiving parts 15, and the base ends 311 of the two connectors 30 extend into the receiving grooves of the two receiving parts 15 respectively.

[0241] In this embodiment, the receiving part 15 may not have a fixing post 151.

[0242] In this third embodiment, the box body 18 and the receiving part 11 can be detachably connected or they can be an integrally connected structure.

[0243] refer to Figure 28 and Figure 29 As shown, the second parts 32 of the two connectors 30 are located on opposite sides of the chip 20. The second parts 32 of the two connectors 30 can be symmetrically arranged on opposite sides of the chip 20, so that the force exerted by the two sets of auxiliary parts 40 on the two connectors 30 is nearly balanced, so that the torque on the chip 20 in the Y-axis direction cancels each other out, ensuring that the chip is subjected to uniform force during use, reducing problems such as displacement and poor electrical contact caused by unbalanced force on the chip 20, thereby improving the reliability of the communication connection between the consumable box and the printing device.

[0244] In this embodiment, reference Figure 30 and Figure 31 As shown, the number of first contacts 22 is the same on both sides of the center line C1 of the substrate 21, and the first contacts 22 can be symmetrically distributed with the center line C1 of the substrate 21 as the axis of symmetry. The base ends 311 of the two connectors 30 respectively abut against the two first contacts 22.

[0245] On opposite sides of the center line C1 of the substrate 21, the number of auxiliary components 40 and the number of first contact pins 51 are matched. When the consumable box and the printing equipment are in the installation state, the auxiliary components 40 located on both sides of the chip 20 deform toward the corresponding first contact pins 51 under the action of external force, until at least a portion of the auxiliary component 40 abuts against the first contact pins 51. At the same time, at least a portion of the second part 32 of the connector 30 deforms toward the corresponding first contact pins 51 under the action of the deformation force and abuts against the first contact pins 51 to form the first contact portion of electrical contact. The corresponding first contact portion is shielded by the shielding part 42 of the corresponding auxiliary component 40, effectively protecting the first contact portion.

[0246] The remaining structure of this second embodiment is the same as that of the first embodiment, and will not be described again here.

[0247] Example 4

[0248] refer to Figure 33 , Figure 34 , Figure 35 and Figure 36 As shown, the difference between this embodiment four and embodiment one is that, in this embodiment four, at least a portion of the first part 31 is configured to extend along the height direction of the box body 10, i.e., the Y-axis direction. The first part 31 includes a connecting part 312, which is connected to the second part 32. The first part 31 also includes a base end 311, and the connecting part 312 is connected between the base end 311 and the second part 32. The connecting part 312 extends along the Y-axis direction.

[0249] refer to Figure 37 , Figure 38 and Figure 39 As shown, the second part 32 includes a bending part 321 and an extension part 322. The extension part 322 can extend along the length direction of the box body 10, i.e., the Z-axis direction, toward the first stylus 51.

[0250] refer to Figure 33 , Figure 38 and Figure 39 As shown, the first contact pin 51 includes a first end 511 and a second end 512. In the height direction of the cartridge body 10, i.e., the Y-axis direction, the second end 512 is further away from the ink outlet 182 at the bottom of the cartridge body 18 than the first end 511. The extension 322 is used to make electrical contact with the second end 512 of the first contact pin 51, and the position where the extension 322 makes electrical contact with the second end 512 forms an outer contact 3221.

[0251] In this embodiment, the outer contact portion 3221 is located at the end of the extension portion 322 away from the bending portion 321, that is, in the length direction of the housing 10, i.e. the Z-axis direction. The outer contact portion 3221 and the bending portion 321 are located at opposite ends of the extension portion 322, and the outer contact portion 3221 can be a linear structure or an arc-shaped structure.

[0252] In one possible implementation method, refer to Figure 33 , Figure 34 and Figure 35 As shown, the box body 10 also includes a support part 19 and a fixing part 101, both of which are disposed on the outer wall surface of the box body 18. Along the height direction of the box body 10, i.e. the Y-axis direction, the fixing part 101 is located between the support part 19 and the receiving part 11, and one end of the fixing part 101 is connected to the receiving surface 111.

[0253] In one possible implementation, the support 19 and the fixing part 101 can be an integral structure formed with the box body 18, or they can be separate structures that can be separated from the box body 18.

[0254] In one possible implementation method, refer to Figure 35 and Figure 36 As shown, the connector 30 also includes a stop portion 33, which is connected to the end of the second part 32 away from the first part 31. A stop cavity 331 is formed in the stop portion 33, which can be fitted onto the fixing part 101. The fixing part 101 can be in the form of a columnar structure, such as a cylindrical or rectangular column. The fixing part 101 extends into the stop cavity 331, which improves the stability of the connector 30 relative to the housing 10.

[0255] In one possible implementation, the stop part 33 may be formed by spirally winding a metal wire, such as copper wire.

[0256] In one possible implementation, the first part 31, the second part 32, and the stop part 33 of the connector 30 can be an integral structure connected as a whole. For example, the integral connector 30 can be made by bending, stamping, or other processes using a single metal wire. This ensures the structural strength of the connector 30 while simplifying the assembly process and improving the reliability and consistency of the connection.

[0257] refer to Figure 34 , Figure 35 and Figure 36 As shown, along the height direction of the housing 10, i.e., the Y-axis direction, the support portion 19 is located above the receiving portion 11. The support portion 19 serves to shield and protect the second part 32 of the connector 30. A protective space is formed within the support portion 19, which can effectively shield the contact point between the outer contact portion 3221 of the extension portion 322 and the second end 512 of the first contact pin 51, preventing dust, impurities, or other external factors from interfering with the contact between the outer contact portion 3221 and the second end 512 of the first contact pin 51. This ensures the long-term cleanliness of the contact point between the extension portion 322 and the second end 512 of the first contact pin 51, and ensures the stability and reliability of the electrical connection between the outer contact portion 3221 of the extension portion 322 and the second end 512 of the first contact pin 51.

[0258] In one possible implementation method, refer to Figure 34 , Figure 35 and Figure 36 As shown, the support portion 19 includes a supporting portion 191 and a folding portion 192 connected to each other. One end of the supporting portion 191 is connected to the box body 18, and the other end of the supporting portion 191 is connected to the folding portion 192. The supporting portion 191 may extend along the length direction of the box body 10, i.e., the Z-axis direction, and the folding portion 192 may extend along the height direction of the box body 10, i.e., the Y-axis direction, thereby forming a protective space between the folding portion 192, the supporting portion 191, and the box body 18. The supporting portion 191 and the folding portion 192 form a physical barrier, which can block and protect the contact position between the extension portion 322 and the first contact pin 51 in the Z-axis and Y-axis directions, effectively isolating external mechanical interference, preventing dust and impurities from falling in and causing accidental short circuits, and ensuring the stability and reliability of the electrical connection.

[0259] In one possible implementation, the outer wall of the box body 18 has a receiving groove 183, the connecting portion 312 of the first portion 31 is located in the receiving groove 183, the receiving groove 183 is recessed toward the interior of the box body 18, and the extension portion 322 extends toward the first stylus 51.

[0260] refer to Figure 38 and Figure 39 As shown, the stylus assembly 50 includes a stylus holder 53, which has a plurality of stylus slots 531. When the consumable box and the printing device are in the installed state, the extension 322 extends into the corresponding stylus slot 531 and abuts against the corresponding first stylus 51 to achieve electrical contact.

[0261] In this fourth embodiment, along the Z-axis direction, the second part 32 of the connector 30 does not extend beyond the side of the stylus groove 531 away from the housing 10.

[0262] When the consumable box and the printing equipment are in the installed state, the second part 32 of the connector 30 extends into the corresponding stylus slot 531 in the stylus holder 53. The extension 322 makes electrical contact with the second end 512 of the first stylus 51 to form a corresponding first contact portion. This first contact portion is shielded by the support part 19 to prevent dust, impurities or other external factors from interfering with the contact between the extension 322 and the second end 512 of the first stylus 51, thus ensuring the stability and reliability of the electrical connection.

[0263] The remaining structure of this embodiment four is the same as that of embodiment one, and will not be described again here.

[0264] Example 5

[0265] refer to Figure 40 , Figure 41 and Figure 42As shown, the difference between this embodiment 5 and embodiment 4 is that in this embodiment 5, the box body 10 does not include the support portion 19. The second part 32 of the connector 30 includes a bent portion 321 and an extension portion 322. The bent portion 321 connects the first part 31 and the extension portion 322. The second part 32 of the connector 30 also includes a protective portion 323, which is located at one end of the extension portion 322 that extends out of the stylus holder 53.

[0266] The protective part 323 can shield the contact position between the extension part 322 and the second end 512 of the first contact pin 51, thereby protecting the contact position between the second end 512 of the first contact pin 51 and providing reliable protection for the electrical contact position between the extension part 322 and the first contact pin 51, ensuring the stability and reliability of the electrical connection.

[0267] In this embodiment, in the length direction of the box 10, i.e. the Z-axis direction, the outer contact portion 3221 is located between the bent portion 321 and the protective portion 323. The protective portion 323 can be a meandering structure, such as an arc-shaped structure.

[0268] In this fifth embodiment, along the Z-axis direction, the second part 32 of the connector 30 extends beyond the side of the pin groove 531 away from the housing 10 and forms a protective part 323, thereby shielding the outer contact 3221 within the pin groove 531. This reduces the problem of environmental pollutants entering the pin groove 531 from the side of the pin groove 531 away from the housing 10, causing the accumulation of environmental pollutants and corrosion of the outer contact 3221 of the extension part 322. It significantly protects the outer contact 3221 from poor contact caused by pollution or corrosion, and improves the stability of the electrical connection between the first pin 51 and the connector 30.

[0269] In one possible implementation, the protective portion 323 may be integrally formed with or separately from the second portion 32 of the connector 30.

[0270] In one possible implementation, the first part 31, the second part 32, and the stop part 33 of the connector 30 can be an integral structure connected as a whole. For example, the integral connector 30 can be made by bending, stamping, or other processes using a single metal wire. This ensures the structural strength of the connector 30 while simplifying the assembly process and improving the reliability and consistency of the connection.

[0271] In one possible implementation method, refer to Figure 40 , Figure 41 and Figure 42 As shown, the box body 10 also includes a fixing part 101, which is disposed on the outer wall surface of the box body 18. Along the height direction of the box body 10, i.e. the Y-axis direction, the fixing part 101 is located above the receiving part 11, and one end of the fixing part 101 is connected to the receiving surface 111.

[0272] In one possible implementation, the fixing part 101 can be an integral structure formed with the box body 18, or it can be a separate structure that can be separated from the box body 18.

[0273] In one possible implementation, the connector 30 further includes a stop portion 33 connected to the end of the second part 32 away from the first part 31. The stop portion 33 forms a stop cavity 331 that can be fitted onto the fixing part 101. The fixing part 101 may be in the form of a columnar structure, such as a cylindrical or rectangular column. The fixing part 101 extends into the stop cavity 331, which improves the stability of the connector 30 relative to the housing 10.

[0274] In one possible implementation, the stop part 33 may be formed by spirally winding a metal wire, such as copper wire.

[0275] When the consumable cartridge and the printing equipment are in the installed state, the second part 32 of the connector 30 passes through the corresponding stylus groove 531 in the stylus holder 53, and the extension 322 makes electrical contact with the second end 512 of the first stylus 51 to form a corresponding first contact part. The protective part 323 extends from the stylus groove 531 to the side of the stylus groove 531 away from the cartridge body 10. The first contact part is shielded by the protective part 323 to prevent dust, impurities or other external factors from interfering with the contact between the extension 322 and the second end 512 of the first stylus 51, and to ensure the stability and reliability of the electrical connection between the first stylus 51 and the connector 30.

[0276] The remaining structure of this fifth embodiment is the same as that of the first embodiment, and will not be described again here.

[0277] Example 6

[0278] refer to Figure 43 , Figure 44 and Figure 45 As shown, the difference between this sixth embodiment and the fourth embodiment is that in this sixth embodiment, the box body 10 further includes a support part 19 and a fixing part 101. Both the support part 19 and the fixing part 101 are disposed on the outer wall surface of the box body 18, and the fixing part 101 is located between the support part 19 and the receiving part 11.

[0279] In one possible implementation, the support part 19 and the fixing part 101 can be an integral structure formed with the box body 18, or they can be separate structures from the box body 18.

[0280] Along the height direction of the box 10, i.e. the Y-axis direction, the support part 19 is closer to the handle 17 than the receiving part 11. The support part 19 is used to improve the stability of the connector 30.

[0281] In one possible implementation, the connector 30 further includes a stop portion 33 connected to the end of the second portion 32 away from the first portion 31. The stop portion 33 forms a stop cavity 331 that can be fitted onto the fixing portion 101. The fixing portion 101 extends into the stop cavity 331, thereby improving the stability of the connector 30 relative to the housing 10.

[0282] In one possible implementation, the stop part 33 may be formed by spirally winding a metal wire, such as copper wire.

[0283] In one possible implementation, the support portion 19 includes a support portion 191 and a folding portion 192 connected to each other. One end of the support portion 191 is connected to the box body 18, and the other end of the support portion 191 is connected to the folding portion 192. A positioning groove 1911 is provided in the support portion 191. A partial bending portion 321 extends into the positioning groove 1911, and an extension portion 322 abuts against the folding portion 192 and extends toward the first stylus 51.

[0284] In one possible implementation, the width of the folded portion 192 is smaller than the width of the support portion 191 in the X-axis direction, and the positioning groove 1911 may be located on both sides of the folded portion 192. The positioning groove 1911 penetrates the upper and lower surfaces of the support portion 191 and extends along the Z-axis direction.

[0285] In one possible implementation, the number of positioning grooves 1911 is the same as the number of bends 321.

[0286] The positioning groove 1911 acts as a visual and physical guide, facilitating the quick and accurate installation of the bent part 321 into the correct position during assembly, reducing assembly difficulty and the skill requirements for operators. Simultaneously, it ensures that the geometry of the second part 32 of the connector 30 remains consistent after assembly, which helps guarantee that the extension 322 is always precisely aligned with the first contact pin 51.

[0287] The folding part 192 provides a side support point for the extension part 322, which greatly reduces the micro-vibration and deformation of the extension part 322, effectively prevents the extension part 322 from undergoing excessive elastic deformation or shaking when subjected to the thrust of the first contact pin 51, and ensures the stable effect of electrical contact.

[0288] Part of the bent portion 321 extends into the positioning groove 1911. The bent portion 321 and the positioning groove 1911 can be connected by an interference fit, which can change the deformation curve of the bent portion 321 under stress, thereby delaying the problem of metal fatigue in the bent portion 321 and improving the service life of the entire connector 30.

[0289] refer to Figure 44 , Figure 46 and Figure 47 As shown, in this embodiment, the second part 32 of the connector 30 includes a bent part 321 and an extension part 322. The bent part 321 is connected between the first part 31 and the extension part 322. The stylus assembly 50 also includes a stylus holder 53, which has a plurality of stylus slots 531. When the consumable box and the printing device are in the installed state, the extension part 322 extends into the corresponding stylus slot 531 and abuts against the corresponding first stylus 51.

[0290] The second part 32 of the connector 30 also includes a protective portion 323, which is located at one end of the extension 322 that extends out of the stylus holder 53. The protective portion 323 can shield the contact position between the extension 322 and the second end 512 of the first stylus 51, thereby protecting the contact position between the second end 512 of the first stylus 51 and ensuring the stability and reliability of the electrical connection between the extension 322 and the second end 512 of the first stylus 51.

[0291] In this embodiment, in the length direction of the box 10, i.e. the Z-axis direction, the outer contact 3221 is located between the bent part 321 and the protective part 323, or the outer contact 3221 is located between the protective part 323 and the stop part 33. The protective part 323 can be a meandering structure, such as an arc-shaped structure.

[0292] In this fifth embodiment, along the Z-axis direction, the second part 32 of the connector 30 extends out of the side of the pin groove 531 away from the housing 10 and forms a protective part 323, thereby shielding the outer contact 3221 inside the pin groove 531. This effectively prevents external dust, moisture and other pollutants from directly invading from the side of the pin groove 531 away from the housing 10, reducing the problem of pollutant accumulation and corrosion of the outer contact 3221 in the environment, and improving the stability of the electrical connection between the extension 322 and the second end 512 of the first pin 51.

[0293] In one possible implementation, the protective portion 323 may be integrally formed with or separately from the second portion 32 of the connector 30.

[0294] In this embodiment, reference Figure 45 and Figure 46 and Figure 47 As shown, the substrate 21 of the chip 20 does not have a notch 212, and the substrate 21 is roughly rectangular.

[0295] When the consumable box and the printing equipment are in the installation state, the extension 322 of the connector 30 extends into the corresponding stylus groove 531, and a portion of the extension 322 extends out of the stylus groove 531 away from the box body 10 to form a protective part 323. At least a portion of the extension 322 makes electrical contact with the corresponding first stylus 51 to form a first contact part. The protective part 323 extending out of the stylus groove 531 is located outside the first contact part, thereby forming a mechanical shield and protection for the first contact part, effectively preventing external interference or physical damage to the first contact part, and improving the stability and durability of the electrical contact between the extension 322 and the first stylus 51.

[0296] There is a gap between the protective portions 323 of the two connectors 30 along the X-axis direction, and the folded portion 192 is inserted into the gap, which improves the supporting effect of the folded portion 192 on the connector 30.
