Technical Field
[0001] The present invention relates to the technical field of electrophotographic imaging, and particularly to a consumable chip, a laser printing consumable provided with the consumable chip, and a printing device provided with the above laser printing consumable. Background Art
[0002] The laser printing consumables installed in existing image forming devices such as printers and copiers are provided with consumable chips for storing printing information. The consumable chips can be detachably installed on the above components, which is convenient for application to different printing components and also convenient for recycling and replacing the chips. The consumable chip has a plurality of first contacts, and the first contacts are used to contact the contact pins of the printing device to establish an electrical connection, so as to realize communication between the printing device and the consumable chip.
[0003] Refer to Figures 1 to 3 , the contact pin structure 91 of a type of existing printing device chip 92 includes a circuit board 911, a plurality of first contact pins 912 and positioning posts 913; the plurality of first contact pins 912 correspond one-to-one to the plurality of first contacts 921 of the chip 92, and the first contact pins 912 are arranged on the circuit board 911 and are used to be electrically connected to the corresponding first contacts 921 of the chip 92; the positioning posts 913 are used to be inserted into the positioning jacks 9221 arranged on the chip substrate 922 in a matching manner, and a second contact pin 9131 is arranged on the circumference of the positioning post 913, and the second contact pin 9131 is used to be electrically connected to the second contact 923 on the inner peripheral wall of the positioning jack 9221. In actual use, the plurality of first contact pins 912 of the contact pin structure 91 of the chip 92 need to contact the plurality of first contacts 921 at different positions on the chip 92 at the same time, and at the same time, it is necessary to ensure that the positioning post 913 is accurately inserted into the positioning jack 9221 of the chip 92 and the second contact pin 9131 is electrically connected to the second contact 923. However, since the first contacts 921 are flat, and affected by the installation position of the chip 92 on the consumable and the installation position of the consumable in the printing device, the force conditions of each first contact 921 and the corresponding first contact pin 912 are different, which is not conducive to the synchronous and reliable contact between the plurality of first contacts 921 and the first contact pins 912, and after the consumable and the printing device are loaded and unloaded multiple times, the first contact pins 912 and / or the second contact pins 9131 of the contact pin structure 91 of the chip 92 are easily damaged, thereby shortening the service life of the printing device. Summary of the Invention
[0004] In order to solve the above problems, the first object of the present invention is to provide a consumable chip that can ensure moderate synchronous electrical contact pressure at multiple points, good contact stability, effectively reduce the risk of damage to the contact pins of the printing device, and extend the service life of the contact pins of the printing device.
[0005] The second object of the present invention is to provide a laser printing consumable that can ensure moderate multi-point synchronous electrical contact pressure, good contact stability, effectively reduce the risk of damage to the printing device's stylus, and extend the service life of the printing device's stylus.
[0006] The third object of the present invention is to provide a printing device that can ensure moderate multi-point synchronous electrical contact pressure, good contact stability, effectively reduce the risk of stylus damage, and extend the service life of the stylus.
[0007] To achieve the first object of the present invention, the present invention provides a consumable chip including a substrate and an electronic module, the electronic module is disposed on the substrate. Wherein, the consumable chip further includes a first pin and a second pin, both the first pin and the second pin extend from the substrate and are electrically connected to the substrate, and the second pin has a plug-in position; in the thickness direction of the substrate, the first pin and the second pin are located on the same side of the substrate; the first pin can be elastically deformed and contact the first stylus of the chip stylus structure of the printing device, and the second pin can be elastically deformed and contact the second stylus on the positioning post of the chip stylus structure, and the positioning post is inserted into the plug-in position.
[0008] As can be seen from the above, compared with the traditional consumable chip using flat contacts, the present consumable chip realizes reasonable dispersion of the contact force through the elastically deformable design of the first pin and the second pin, enabling the contact pressure at each contact point between the consumable chip and the chip stylus structure in the printing device to be adaptively adjusted, preventing the contact pressure at a certain contact point from being too large or too small, avoiding damage to the chip contact structure due to excessive local pressure, and ensuring the stability and reliability of the contact between the first pin and the first stylus of the chip stylus structure, as well as the stability and reliability of the contact between the second pin and the positioning post and the second stylus of the chip stylus structure, thereby ensuring the establishment of stable communication between the consumable chip and the printing device.
[0009] A further solution is that the number of the first pins is more than two; the second pin and more than two first pins are regularly arranged, or the second pin and more than two first pins are dispersedly arranged.
[0010] As can be seen from the above, adding the first pin enables the consumable chip to transmit and / or receive more types of data, enriches the functions of the consumable chip, improves the practicality of the consumable chip, and also helps to expand the applicable range of the consumable chip; the distribution between the first pin and the second pin is flexible, enabling the first pin and the second pin of the consumable chip to be set according to different types and models of printing devices to meet the usage requirements of the printing device.
[0011] In a preferred solution, the first pin is in the shape of a cylindrical helix, or the first pin is in the shape of a conical helix or a frustum helix, and the top end of the first pin is connected to the substrate; the second pin is in the shape of a cylindrical helix, and an insertion position is formed in the middle of the second pin in the shape of a cylindrical helix, or the second pin is in the shape of a conical helix or a frustum helix, and an insertion position is formed in the middle of the second pin in the shape of a conical helix or a frustum helix, and the top end of the second pin is connected to the substrate.
[0012] As can be seen from the above, the spring-shaped first pin can stably and reliably contact the first contact pin of the chip contact pin structure with appropriate pressure. Similarly, the spring-shaped second pin can stably and reliably contact the positioning post and the second contact pin of the chip contact pin structure with appropriate pressure to achieve stable communication between the consumable chip and the printing device; among them, the second contact pin forms an insertion position through its own spiral structure, which can enable the substrate not to be additionally provided with a jack to cooperate with the positioning post, and there is no need to provide a contact point in the jack, which helps to simplify the processing structure of the substrate and reduce the processing cost of the consumable chip.
[0013] A further solution is that the diameters of all the first pins are equal, or at least some of the first pins have unequal diameters; the wire diameters of all the first pins are equal, or at least some of the first pins have unequal wire diameters; in the thickness direction, the heights of all the first pins are equal, or at least some of the first pins have unequal heights.
[0014] As can be seen from the above, this design enables each contact point to be more flexibly and adaptively adjusted according to the relative position between the consumable chip and the chip contact pin structure, ensuring that the contact pressure at each contact point remains in the best state, thereby better avoiding damage to the chip contact pin structure.

[0016] As can be seen from the above, the above design can ensure that the first pin stably and reliably contacts the first contact pin of the chip contact pin structure with appropriate pressure, and the second pin stably and reliably contacts the positioning post and the second contact pin of the chip contact pin structure with appropriate pressure to achieve stable communication between the consumable chip and the printing device; among them, the second contact pin forms an insertion position through its own multiple elastic pieces, which can enable the substrate not to be additionally provided with a jack to cooperate with the positioning post, and there is no need to provide a contact point in the jack, which helps to simplify the processing structure of the substrate and reduce the processing cost of the consumable chip.
[0017] A further solution is that the first pin is made of conductive metal, or the first pin is made of conductive rubber; the second pin is made of conductive metal, or the second pin is made of conductive rubber.
[0018] As can be seen from the above, the pin material can be flexibly selected according to cost and usage requirements, and the stability and reliability of the communication between the pin and the chip contact structure can be ensured.
[0019] Another preferred solution is that the first pin includes a first fixed cylinder, a movable pin and a first elastic member. The first fixed cylinder is connected to the substrate. The movable pin is movably connected to the first fixed cylinder in the axial direction of the first fixed cylinder. The first elastic member is arranged between the first fixed cylinder and the movable pin, and the first elastic member forces the movable pin to move away from the substrate. The second pin includes a second fixed cylinder, a movable cylinder and a second elastic member. The second fixed cylinder is connected to the substrate. The movable cylinder is movably connected to the second fixed cylinder in the axial direction of the second fixed cylinder. The second elastic member is arranged between the second fixed cylinder and the movable cylinder, and the second elastic member forces the movable cylinder to move away from the substrate. A plug-in position is provided on the movable cylinder.
[0020] As can be seen from the above, the first pin adopts a telescopic structure. By using the elastic member to force the movable pin to move away from the substrate, and the second pin adopts a telescopic structure. By using the elastic member to force the movable cylinder to move away from the substrate, the first pin can stably and reliably contact the first contact pin of the chip contact structure, and the second pin can stably and reliably contact the positioning post and the second contact pin of the chip contact structure with appropriate pressure, so as to ensure the stable communication between the consumable chip and the printing device. In particular, the movable cylinder of the second pin cooperates with the positioning post through its own plug-in position, so that the substrate does not need to be additionally provided with a jack for the positioning post and the contacts in the jack, effectively simplifying the substrate processing structure and reducing the manufacturing cost of the consumable chip.
[0021] A further solution is that the substrate is provided with a through hole at the position of the second pin.
[0022] As can be seen from the above, the through hole can cooperate with the positioning post on the chip contact structure to better ensure the relative position between the consumable chip and the chip contact structure.
[0023] To achieve the second object of the present invention, the present invention provides a laser printing consumable, including a housing. Among them, the above-mentioned consumable chip is further included, and the consumable chip is installed on the housing.
[0024] As can be seen from the above, the laser printing consumable using the above-mentioned consumable chip can ensure the stability of multi-point synchronous electrical contact with the chip contact structure, reduce the risk of damage to the chip contact structure, and extend the service life of the contact pins of the printing device.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION OF THE INVENTION
[0037] The First Embodiment of the Consumable Chip Refer to Figure 4 and Figure 5, the consumable chip 1 includes a substrate 11, an electronic module 12, a first pin 13, and a second pin 14. In the thickness direction of the substrate 11, the electronic module 12 and the first pin 13 are preferably located on opposite sides of the substrate 11, and the first pin 13 and the second pin 14 are located on the same side of the substrate 11. The electronic module 12 includes a memory and a controller. The memory is used to store data and record the static and dynamic information of the consumable, and the controller is used to process data, perform security verification, and manage the interaction between the laser printing consumable and the printing device. Of course, as another alternative solution, the electronic module 12, the first pin 13, and the second pin 14 can also be all arranged on the same side of the substrate 11.
[0038] The first pin 13 extends from the substrate 11 and is electrically connected to the substrate 11, and the first pin 13 can be elastically deformed; the second pin 14 extends from the substrate 11 and is electrically connected to the substrate 11, and the second pin 14 can be elastically deformed, wherein the second pin 14 has a plug-in position 140. The first pin 13 is used to electrically connect with the first contact pin 21 of the chip contact pin structure 2 in the printing device, and the second pin 14 is used to electrically connect with the second contact pin 221 on the positioning post 22 of the chip contact pin structure 2, so as to establish communication between the consumable chip 1 and the printer; the plug-in position 140 on the second pin 14 is used to cooperate and connect with the positioning post 22 of the chip contact pin structure 2 to realize the positioning between the consumable chip 1 and the chip contact pin structure 2.
[0039] Compared with the traditional consumable chip using flat contacts, through the elastically deformable design of the first pin 13 and the second pin 14, the present invention enables both the first pin 13 and the second pin 14 to have the characteristic of self-adaptive adjustment of contact pressure, realizing the reasonable dispersion of the contact pressure at each contact point (such as the contact point between the first pin 13 and the first contact pin 21, the contact point between the second pin 14 and the second contact pin 221, etc.); when cooperating with the chip contact pin structure 2 in the printing device, this design can make the contact pressure at each contact point automatically balanced according to the actual plugging state (such as the relative position between the first pin 13 and the first contact pin 21, the relative position between the second pin 14 and the positioning post 22 and the second contact pin 221, etc.), effectively avoiding the structural damage caused by excessive pressure at a single contact point, and at the same time preventing the contact failure problem caused by insufficient contact pressure. Specifically, when the first pin 13 contacts the first contact pin 21 of the chip contact pin structure 2, it adaptively matches the contact force through elastic deformation to ensure the stable and reliable electrical connection; the second pin 14 with the plug-in position 140, when cooperating with the positioning post 22 and the second contact pin 221, can not only compensate for the plugging error through elastic deformation, but also maintain the double stability of positioning guidance and electrical connection, thus solving the technical problem of uneven pressure of traditional flat contacts from the perspective of contact mechanics optimization, and finally realizing a stable and durable communication connection between the consumable chip 1 and the printing device.
[0040] The number of the first pins 13 is preferably more than two; the second pin 14 and more than two first pins 13 are arranged regularly or the second pin 14 and more than two first pins 13 are arranged dispersedly. Among them, the regular arrangement includes array distribution, symmetric distribution, T-shaped distribution, cross-shaped distribution, star-shaped distribution, etc. The standardized pin layout forms a preset corresponding relationship with the print device stylus structure, which is convenient for realizing modular adaptation, especially suitable for the equipment scenarios of serialized and standardized production, and can reduce the adaptation cost of the equipment and consumables through unified pin pitch and distribution rules; when arranged dispersedly, the pin group can be flexibly adjusted according to the different layouts of the stylus structures of different device chips 2; in non-regular or compact device interfaces, the dispersed pins can avoid the space interference area and accurately match the stylus positions, avoiding contact blind areas or mechanical conflicts caused by fixed layouts, and significantly improving the compatibility of the consumable chip 1 in heterogeneous devices. In this embodiment, for example, the number of the first pins 13 is three, and the three first pins 13 and the second pin 14 are generally arranged in a straight line.
[0041] The parallel design of multiple first pins 13 can provide more diversified data interaction channels for the material chip, and can support the synchronous transmission and reception of multiple types of data (such as consumable status parameters, work instructions, fault feedback, etc.) at the same time, solve the limitation problem of single-signal transmission using a single pin, enable the chip to carry more complex communication protocols, and significantly improve its function integration and practicability; the physical redundancy characteristic of multiple pins can also maintain an effective data link through other pins when some contacts accidentally have poor contact, further enhancing the stability of signal transmission. It can be seen that through the number configuration and flexible distribution of multiple pins, both the data interaction ability of the consumable chip 1 is expanded, and the problems of single function and poor device adaptability of traditional single pins are solved through adaptive layout, providing structural support for improving the practicability and market versatility of the consumable chip 1.
[0042] In this embodiment, the first pin 13 is in a frustum spiral shape, and the small-diameter end of the first pin 13 in the frustum spiral shape is connected to the substrate 11; the second pin 14 is in a frustum spiral shape, and the small-diameter end of the second pin 14 in the frustum spiral shape is connected to the substrate 11. This design enables the first stylus 21 of the chip stylus structure 2 to better contact the first pin 13, enables the positioning post 22 of the chip stylus structure 2 to better insert into the insertion position 140, and enables the second stylus 221 on the positioning post 22 to better contact the second pin 14.
[0043] It can be understood that, in some embodiments, the first pin 13 can also be in a cylindrical spiral shape or a conical spiral shape. When the first pin 13 is in a conical spiral shape, the small-diameter end of the first pin 13 in the conical spiral shape is connected to the substrate 11. Similarly, in some embodiments, the second pin 14 can also be in a cylindrical spiral shape or a conical spiral shape. When the second pin 14 is in a conical spiral shape, the small-diameter end of the second pin 14 in the conical spiral shape is connected to the substrate 11.
[0044] By designing the first pin 13 and the second pin 14 as cylindrical spiral, conical spiral or frustum spiral structures, the spiral first pin 13 can utilize the spring-like elastic deformation characteristics. When contacting the first contact pin 21 of the chip contact pin structure 2, it can automatically adjust the contact pressure according to the relative position between the first pin 13 and the first contact pin 21, avoiding both the pressure overload caused by rigid contact and compensating for the contact gap caused by the installation position error of the laser printing consumables, ensuring that the contact interface always maintains a stable conductive pressure, significantly improving the contact reliability compared with traditional rigid pins, and avoiding the first contact pin 21 of the chip contact pin structure 2 from being over-extruded. The insertion position 140 formed in the middle of the spiral second pin 14 can achieve double contact with pressure self-adaptation with the positioning post 22 and the second contact pin 221 of the chip contact pin structure 2 by virtue of the elastic inclusiveness of the spiral structure. On the one hand, it forms an elastic engagement with the positioning post 22 through the inner edge of the spiral to provide stable mechanical positioning. On the other hand, it maintains elastic conductive contact with the second contact pin 221 through the large-diameter end face and / or the inner edge of the spiral, ensuring the synchronous and stable realization of the positioning function and the electrical connection function. In the traditional solution, separate jacks need to be machined on the substrate 11 to cooperate with the positioning posts 22, and independent contacts are arranged in the jacks. However, in this design, the insertion position 140 is formed by the spiral structure of the second pin 14 itself, directly omitting the jack structure and the built-in contacts on the substrate 11, reducing both the processing procedures of the substrate 11 (such as drilling and contact welding) and avoiding the contact problems caused by the accuracy error of the jacks, simplifying the chip structure at the hardware level and effectively reducing the material cost and the manufacturing process difficulty. Of course, jacks can still be provided on the substrate 11 for cooperation with the positioning posts 22.
[0045] In addition, the structures of the first pins 13 may be the same or different, and the structures of the first pins 13 and the second pins 14 may be the same or different. Specifically, as follows: the diameters of the first pins 13 are equal, or the diameters of at least some of the first pins 13 are not equal; the wire diameters of the first pins 13 are equal, or the wire diameters of at least some of the first pins 13 are not equal; in the thickness direction, the heights of the first pins 13 are equal, or the heights of at least some of the first pins 13 are not equal. In this embodiment, the structures of the first pins 13 are the same, while the structures of the first and second pins 14 are different. By allowing differences in the diameter, wire diameter, or height of the first pins 13, the adaptive advantage of the contact pressure of each pin can be better exerted. Specifically: the first pins 13 with different diameters or wire diameters have different elastic deformation amounts and contact stiffnesses, and can be dynamically adjusted according to the local contact requirements of the chip contact pin structure 2. For example, pins with a thinner wire diameter are used in areas with a greater pressure on the first contact pins 21 of the chip contact pin structure 2, and their high elasticity compensates for the overload pressure; pins with a thicker diameter are used in areas with high contact accuracy requirements, and their low deformation amount maintains a stable contact posture, so as to achieve pressure equalization of the entire contact interface; and so on. The height differences of the first pins 13 in the thickness direction of the substrate 11 can actively adapt to the three-dimensional position deviation of the device contact pin structure; when there is an installation error or insertion / removal tilt in the height direction of the contact pins, the pins with different heights automatically compensate for the contact displacement through the difference in their effective contact lengths, avoiding local contact failure or pressure concentration problems caused by a rigidly consistent height.
[0046] Through the above parameter differentiation design, the contact pressure of each contact point can be independently adjusted to the optimal threshold (neither overloaded nor loose contact), fundamentally eliminating the risk of abnormal pressure caused by the consistent design of traditional pins with the same parameters. It can not only prevent mechanical damage or conductive layer wear to the chip contact pin structure 2 caused by high-pressure points, but also avoid signal transmission failures caused by an increase in contact resistance at low-pressure points, ultimately achieving a double improvement in the durability and communication stability of the contact system.
[0047] In summary, compared with the consumable chip using a flat contact in the traditional way, through the elastic deformation design of the first pins 13 and the second pins 14, the consumable chip 1 realizes a reasonable dispersion of the contact force, enabling the contact pressure of each contact point between the consumable chip 1 and the chip contact pin structure 2 in the printing device to be adaptively adjusted, preventing the contact pressure at a certain contact point from being too large or too small, avoiding damage to the chip contact structure due to excessive local pressure, and ensuring the stability and reliability of the contact between the first pins 13 and the first contact pins 21 of the chip contact pin structure 2, as well as the stability and reliability of the contact between the second pins 14 and the positioning posts 22 and the second contact pins 221 of the chip contact pin structure 2, thereby ensuring the establishment of stable communication between the consumable chip 1 and the printing device.
[0048] Second Embodiment of the Consumable Chip Reference Figure 6 and Figure 7 , the difference between this embodiment and the first embodiment of the consumable chip lies in the structures of the first pin and the second pin. Specifically, in this embodiment: The first pin 32 of the consumable chip 3 is in a single sheet shape; the second pin 33 includes two or more second elastic pieces 331, and an insertion position is formed between the two or more second elastic pieces 331. Preferably, the free end of the first pin 32 away from the substrate 31 has a first bending portion, and the first bending portion is bent obliquely away from the first contact pin 21 of the chip contact pin structure 2, so that the first bending portion forms a guiding structure and / or appropriately increases the elastic force for pressing and fixing the first pin 32 on the first contact pin 21, thereby ensuring that the first pin 32 and the first contact pin 21 maintain stable and reliable contact; similarly, the free end of the second elastic piece 331 away from the substrate 31 has a second bending portion, and the second bending portion is bent obliquely away from the positioning post 22 of the chip contact pin structure 2, so that the second bending portion forms a guiding structure and / or appropriately increases the elastic force for pressing and fixing the second pin 33 on the second contact pin 221, thereby ensuring that the second pin and the second contact pin 221 maintain stable and reliable contact.
[0049] Of course, as another solution, in some embodiments, the first pin 32 includes two or more first elastic pieces. At this time, a clamping position is formed between the two or more first elastic pieces to accommodate the first contact pin 21 and engage with the first contact pin 21.
[0050] By designing the first pin 32 as a single sheet shape or a multi-elastic piece clamping position structure and the second pin 33 as a multi-elastic piece insertion position structure, the consumable chip 3 has the following advantages: The first pin 32 with a single sheet shape realizes flexible contact with the first contact pin 21 by virtue of its own elastic deformation, and can adaptively compensate for the angular deviation during the plugging and unplugging process; the clamping position structure formed by two or more first elastic pieces forms a wrapped contact with the first contact pin 21 through the elastic tension between the elastic pieces, which not only disperses the contact pressure through multi-point contact to avoid overloading of a single contact point, but also enhances the stability of the contact posture by using the mechanical limiting effect of the clamping position to ensure the reliability of the conductive connection. The second pin 33 forms an insertion position through multiple second elastic pieces 331, and realizes clamping and positioning with the positioning post 22 of the chip contact pin structure 2 through the elastic deformation of the outward or inward contraction of the elastic pieces. At the same time, the inner side or edge of the elastic piece maintains elastic electrical contact with the second contact pin 221, integrating the mechanical positioning function and the electrical connection function into the same structure. By virtue of the cooperative elastic deformation of the elastic piece group, a stable contact pressure can be maintained under different plugging and unplugging forces.
[0051] In addition, the traditional solution requires separate processing of jacks on the substrate 31 to fix the positioning posts 22, and independent contacts are arranged on the inner walls of the jacks for electrical connection. In this design, the insertion positions are directly formed by the multi-elastic pieces of the second pins 33, eliminating the need to add jacks and built-in contacts on the substrate 31, reducing the processing procedures such as drilling the substrate 31 and soldering the contacts, avoiding the problem of poor contact caused by the accuracy error of the jacks, simplifying the chip structure from the hardware architecture, and significantly reducing the material cost and manufacturing complexity.
[0052] Of course, jacks 311 can still be arranged on the substrate 31 for cooperation with the positioning posts 22; this design is beneficial to reducing the distance between the chip pin mechanism and the consumable chip 3, thereby facilitating the improvement of the powder cartridge capacity of the laser printing consumables.
[0053] Among them, the first pin 32 is made of conductive metal, or the first pin 32 is made of conductive rubber; the second pin 33 is made of conductive metal, or the second pin 33 is made of conductive rubber.
[0054] The third embodiment of the consumable chip Refer to Figure 8 and Figure 9 This embodiment is different from the first embodiment of the consumable chip in the structures of the first pin and the second pin 43. Specifically, in this embodiment: The first pin 42 of the consumable chip 4 includes a first fixing cylinder 421, a movable pin 422 and a first elastic member. The first fixing cylinder 421 is connected to the substrate 41. The movable pin 422 is movably connected to the first fixing cylinder 421 in the axial direction of the first fixing cylinder 421. The first elastic member is arranged between the first fixing cylinder 421 and the movable pin 422, and the first elastic member forces the movable pin 422 to move away from the substrate 41; the first elastic member is preferably a compression spring, and the first elastic member can establish an electrical connection between the first fixing cylinder 421 and the movable pin 422. Of course, an electrical connection can also be directly achieved between the first fixing cylinder 421 and the movable pin 422.
[0055] The second pin 43 of the consumable chip 4 includes a second fixing cylinder 431, a movable cylinder 432 and a second elastic member. The second fixing cylinder 431 is connected to the substrate 41. The movable cylinder 432 is movably connected to the second fixing cylinder 431 in the axial direction of the second fixing cylinder 431. The second elastic member is arranged between the second fixing cylinder 431 and the movable cylinder 432, and the second elastic member forces the movable cylinder 432 to move away from the substrate 41. An insertion position 430 is arranged on the movable cylinder 432; the second elastic member is preferably a compression spring, and the second elastic member can establish an electrical connection between the second fixing cylinder 431 and the movable cylinder 432. Of course, an electrical connection can also be directly achieved between the second fixing cylinder 431 and the movable cylinder 432.
[0056] After the consumable chip 4 is installed in the printing device along with the printing consumable, the movable pin 422 moves towards the first contact pin 21 of the chip contact pin structure 2 under the action of the second elastic member and abuts tightly against the first contact pin 21; the movable cylinder 432 moves towards the positioning post 22 of the chip contact pin structure 2 under the action of the second elastic member, so that the positioning post 22 is inserted into the insertion position 430, and the movable cylinder 432 abuts tightly against the second contact pin 221.
[0057] By designing the first pin 42 and the second pin 43 as an elastic telescopic structure, the consumable chip 4 has the following advantages: The movable pin 422 of the first pin 42 maintains a pre-tightening force away from the substrate 41 under the action of the first elastic member. When contacting the first contact pin 21 of the chip contact pin structure 2, the contact pressure is adaptively adjusted through the axial sliding of the movable pin 422 in the first fixed cylinder 421; when the pressure is large, the movable pin 422 compresses the elastic member to slow down the rigid impact; when the pressure is small, the first elastic member pushes the movable pin 422 to maintain effective contact, ensuring that the contact pressure is always maintained in the optimal range of electrical conductivity, significantly improving the contact stability under complex working conditions compared with traditional rigid pins.
[0058] The movable cylinder 432 of the second pin 43 forms a telescopic insertion position 430 under the action of the second elastic member. When cooperating with the positioning post 22 of the chip contact pin structure 2, the elastic pre-tightening force causes an elastic engagement between the outer edge of the movable cylinder 432 and the positioning post 22, providing stable mechanical positioning; at the same time, the inner wall or end face of the movable cylinder 432 maintains elastic electrical contact with the second contact pin 221, compensating for the axial displacement deviation during the insertion and extraction process through the deformation of the second elastic member, and reliably realizing the positioning function and the electrical connection function synchronously.
