A chip plug-in card socket

Abstract

This utility model discloses a chip insertion socket, including a socket frame. A positioning frame is slidably provided on the inner wall of the socket frame. Two first trapezoidal seats are fixedly provided on one side of the top of the positioning frame, and a limiting plate is fixedly provided on the top of the socket frame. This utility model, by providing the first and second trapezoidal seats, places the chip inside the positioning frame and pushes it inward. The inward movement of the positioning frame causes the first trapezoidal seats to move inward. When the first trapezoidal seat contacts the second trapezoidal seat, as the first trapezoidal seat continues to move, it causes the second trapezoidal seat to move upward until the positioning frame moves into the socket frame. This method ensures a stable contact pressure between the chip and the socket, preventing minute displacement or gaps between the socket terminals and chip pins when the device encounters vibration, impact, or temperature changes. This reduces contact resistance, does not hinder signal transmission, and maintains data transmission stability and speed.

Description

Technical Field

[0001] This utility model relates to the field of chip card socket technology, specifically a chip plug-in card socket. Background Technology

[0002] In fields such as consumer electronics, industrial control, automotive electronics, and IoT devices, chips, as core components responsible for computing, data storage, and signal conversion, need to be detachably electrically connected to the circuit motherboard via pluggable sockets. This connection method is not only a key support for chip debugging and calibration before leaving the factory and assembly and testing during the production process, but also directly determines the convenience of later maintenance and repair (such as chip replacement due to failure) and functional upgrades (such as expanding storage chips). It is an important link in ensuring the availability of electronic devices throughout their entire life cycle.

[0003] Currently, when using pluggable card sockets to insert chips, the electrical connection mainly relies on the physical contact and mating structure of "elastic terminal - chip pin". When the equipment is subjected to vibration, impact or temperature change, it is easy to cause a small displacement or gap between the card socket terminal and the chip pin, thereby increasing the contact resistance, hindering signal transmission, and reducing the stability and speed of data transmission. Therefore, a pluggable chip card socket is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a chip-pluggable card socket to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a chip plug-in card socket, comprising:

[0006] A card holder frame, wherein a positioning frame is slidably provided on the inner wall of the card holder frame, two first trapezoidal seats are fixedly provided on one side of the top of the positioning frame, and a limiting plate is fixedly provided on the top of the card holder frame;

[0007] A clamping component includes a clamping pad, the outer wall of which penetrates the middle of the top of the limiting plate. Horizontal plates are fixedly provided on both sides of the clamping pad, and springs are fixedly provided at the bottom ends of both horizontal plates. A second trapezoidal seat is fixedly provided at the opposite ends of both horizontal plates, and the hypotenuse of the second trapezoidal seat is adapted to the hypotenuse of the first trapezoidal seat.

[0008] Furthermore, the bottom end of the spring is fixedly connected to the top end of the limiting plate, and the outer wall of the second trapezoidal seat penetrates the side of the top end of the limiting plate.

[0009] Furthermore, the inner bottom end of the positioning frame and the inner bottom end of the card holder frame are located on the same horizontal plane.

[0010] Furthermore, the bottom end of the pressing pad is provided with several fixing grooves, and a rubber roller is rotatably provided inside the fixing groove. The bottom end of the rubber roller is located on the same horizontal plane as the bottom end of the pressing pad.

[0011] Furthermore, slide bars are fixedly provided on both sides of the positioning frame, and the outer walls of the two slide bars are slidably connected to the two sides of the inner wall of the card seat frame, respectively.

[0012] Furthermore, the plurality of the fixed slots are arranged in a matrix.

[0013] Furthermore, it also includes a fixing component, which includes an L-shaped rod. One end of the L-shaped rod is rotatably disposed at the open end of the card holder frame. An elastic block is fixedly disposed on one side of the L-shaped rod. A card holder is engaged with the outer wall of the elastic block. One side of the card holder is fixedly disposed on one side of the positioning frame.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a first trapezoidal seat and a second trapezoidal seat. The chip is placed inside a positioning frame and pushed inwards. The inward movement of the positioning frame causes the first trapezoidal seat to move inwards as well. Once the first trapezoidal seat contacts the second trapezoidal seat, its continued movement causes the second trapezoidal seat to move upwards. This, in turn, causes a horizontal plate to move a pressure pad upwards, simultaneously stretching a spring. Under the elastic force of the spring, the pressure pad presses the chip firmly until the positioning frame moves inside the card holder frame. This method ensures a stable contact pressure between the chip and the card holder, preventing minute displacements or gaps between the card holder terminals and chip pins when the device experiences vibration, impact, or temperature changes. This reduces contact resistance, does not hinder signal transmission, and maintains data transmission stability and speed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a chip plug-in card socket, comprising:

[0026] Card seat frame 11, with a positioning frame 12 slidably provided on the inner wall of the card seat frame 11, and two first trapezoidal seats 13 fixedly provided on one side of the top of the positioning frame 12, and a limiting plate 14 fixedly provided on the top of the card seat frame 11.

[0027] The inner bottom of the card holder frame 11 is provided with multiple sets of elastic terminals. The positioning frame 12 is used to place and position the chip, making it easy to insert the chip into the card holder frame 11. The limiting plate 14 is used to limit and fix the top of the chip.

[0028] The clamping component includes a clamping pad 21. The outer wall of the clamping pad 21 penetrates the middle of the top of the limiting plate 14. Horizontal plates 22 are fixed on both sides of the clamping pad 21. Springs 23 are fixed at the bottom of both horizontal plates 22. Second trapezoidal seats 24 are fixed at opposite ends of both horizontal plates 22, and the hypotenuse of the second trapezoidal seat 24 is adapted to the hypotenuse of the first trapezoidal seat 13.

[0029] The pressing pad 21 and the limiting plate 14 are in sliding fit, and the bottom end of the pressing pad 21 and the bottom end of the second trapezoidal seat 24 are on the same horizontal plane.

[0030] The bottom end of the spring 23 is fixedly connected to the top end of the limiting plate 14, and the outer wall of the second trapezoidal seat 24 penetrates the side of the top end of the limiting plate 14.

[0031] The second trapezoidal seat 24 slides in conjunction with the limiting plate 14.

[0032] The inner bottom end of the positioning frame 12 and the inner bottom end of the card holder frame 11 are on the same horizontal plane.

[0033] The bottom end of the pressing pad 21 is provided with several fixing grooves 211, and a rubber roller 212 is rotatably provided on the inner side of the fixing groove 211. The bottom end of the rubber roller 212 and the bottom end of the pressing pad 21 are located on the same horizontal plane.

[0034] The rubber roller 212 can change the sliding friction between the chip and the pressure pad 21 into rolling friction when the chip is inserted into the card holder frame 11, thereby reducing the friction between the two and minimizing damage to the chip.

[0035] Slides 15 are fixedly provided on both sides of the positioning frame 12, and the outer walls of the two slides 15 are slidably connected to the two sides of the inner wall of the card seat frame 11 respectively.

[0036] The slide bar 15 is T-shaped and is used to limit the movement of the positioning frame 12 so that it slides horizontally along the direction of the slide bar 15. Both sides of the inner wall of the card seat frame 11 are provided with slide grooves that are adapted to the slide bar 15, and the narrow side end of the slide bar 15 passes through one end of the slide groove to the outside of the card seat frame 11.

[0037] Several fixed slots 211 are arranged in a matrix.

[0038] Working principle: When installing the chip, pull the positioning frame 12 outward until the sliders 15 on both sides of the positioning frame 12 slide outward to one end of the groove. After placing the chip inside the positioning frame 12, push the positioning frame 12 inward. The inward movement of the positioning frame 12 causes the first trapezoidal seat 13 to move inward. When the first trapezoidal seat 13 contacts the second trapezoidal seat 24, as the first trapezoidal seat 13 continues to move, it causes the second trapezoidal seat 24 to move upward. The upward movement of the second trapezoidal seat 24 causes the horizontal plate 22 to move upward. The upward movement of the horizontal plate 22 causes the pressure pad 21 to move upward, while simultaneously stretching the spring 23. Under the elastic action of the spring 23, the pressure pad 21 presses the chip until the positioning frame 12 moves into the card holder frame 11. In this way, the chip and the card holder can always maintain a stable contact pressure, avoiding small displacements or gaps between the card holder terminals and chip pins when the equipment is subjected to vibration, impact or temperature changes, thereby reducing contact resistance, not hindering signal transmission, and maintaining the stability and speed of data transmission.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The fixing component includes an L-shaped rod 31, one end of which is rotatably disposed at the open end of the card seat frame 11. An elastic block 32 is fixedly disposed on one side of the L-shaped rod 31, and a card seat 33 is engaged with the outer wall of the elastic block 32. One side of the card seat 33 is fixedly disposed on one side of the positioning frame 12.

[0041] The card holder 33 has a card hole on one side that is compatible with the elastic block 32. When the L-shaped rod 31 is rotated upward to the vertical position, the slide bar 15 moves outward and does not contact the L-shaped rod 31.

[0042] Working principle: When the positioning frame 12 moves into the card seat frame 11, the L-shaped rod 31 is rotated. The rotation of the L-shaped rod 31 drives the elastic block 32 to move until the elastic block 32 on the L-shaped rod 31 engages with the card seat 33. This facilitates the positioning frame 12 to be limited and fixed, ensuring the stability of the connection between the positioning frame 12 and the card seat frame 11.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
