Abstract
Description
Technical Field
[0001] This utility model relates to the field of crimping assembly technology, specifically a damage-resistant crimping fixture. Background Technology
[0002] Electronic connectors, also known as circuit connectors, are components used to complete electrical connections between circuits or electronic devices; they are essentially bridges between the two. Electronic connectors consist of several components, and their termination methods typically include soldering, crimping, wrapping, piercing, and screw connections.
[0003] Patent (CN220209588U) discloses a crimping fixture for a latch connector. The depth of the concave orifice and the length of the solderless pin inside the latch connector are 1:1 equivalent. The bottom of the mounting fixture is made into a suitable rectangular structure according to the shape of the mounting groove inside the latch connector. The rectangular surface of the bottom of the mounting fixture is completely embedded into the mounting groove inside the latch connector, increasing the force-bearing area. The top block of the fixture increases the height of the fixture itself, which is beneficial for the latch connector to carry the spring-type latch accessories for PCB board crimping, simplifying the latch connector installation process. The top plane of the fixture is widened to facilitate contact with a manual press. The fixture itself is made of aluminum alloy, has a small size, and avoids the complicated steps of crimping on large machines monopolized by foreign countries.
[0004] The connector crimping fixtures described in the aforementioned patent documents rely primarily on the set stroke of a manual press or the downward pressure applied by the operator to determine the lower position of the fixture, which can easily damage the connectors. Summary of the Invention
[0005] The purpose of this invention is to provide a damage-resistant crimping fixture to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a damage-resistant crimping fixture, comprising a base plate, a pressure plate and a base, wherein the base is horizontally disposed between the base plate and the pressure plate, a clamping mechanism is provided on the top of the base, a limiting block is provided on one side of the clamping mechanism on the top of the base, and an elastic limiting mechanism is provided on the other side of the clamping mechanism on the top of the base.
[0007] Furthermore, a number of guide posts are provided between the base plate and the pressure plate. The bottom of the guide post is fixedly connected to the top of the base plate, and one end of the guide post extends through and above the pressure plate. The guide post is slidably connected to the pressure plate.
[0008] Furthermore, the top of the pressure plate is provided with a linear bearing that matches the guide post, the linear bearing is slidably sleeved on the outer wall of the guide post, and a first spring is provided between the bottom plate and the pressure plate, the first spring being sleeved on the outer wall of the guide post.
[0009] Furthermore, the elastic limiting mechanism includes a U-shaped limiting plate and several second springs. The second springs are vertically disposed at the bottom of the U-shaped limiting plate, and a support sleeve is sleeved on the outer wall of the second spring at the bottom of the U-shaped limiting plate.
[0010] Furthermore, the base has a buffer groove at the top that matches the U-shaped limiting plate, and the inner wall of the base has a limiting groove at the top of the buffer groove that matches the supporting sleeve.
[0011] Furthermore, the top of the U-shaped limiting plate is symmetrically provided with support blocks on both sides, a first flexible pad is provided between the two support blocks, and a second flexible pad is provided on the top of the U-shaped limiting plate below the first flexible pad.
[0012] Furthermore, the bottom of the first flexible pad is provided with a first limiting tooth groove, and the top of the second flexible pad is provided with a second limiting tooth groove.
[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0014] 1. This utility model, by setting a base, a clamping mechanism, a limiting block, and an elastic limiting mechanism, uses a base plate and a pressure plate to perform a pressing operation on the electrical connector on the top of the base. The clamping mechanism is used to clamp and fix the electrical connector on the top of the base, which can effectively ensure the safety and stability of the electrical connector during the pressing operation. The limiting block and the elastic limiting mechanism are located on the top of the base. The limiting block on one side of the clamping mechanism provides limiting support at the lower pressing limit position of the pressure plate to avoid damage to the electrical connector by the pressure plate. The elastic limiting mechanism on the other side of the clamping mechanism provides limiting support at the lower pressing limit position of the pressure plate to avoid damage to the electrical connector by the pressure plate.
[0015] 2. In this utility model, the cable of the electrical connector is placed inside the U-shaped limiting plate. The two vertices of the U-shaped limiting plate contact and support the bottom of the pressure plate, which can effectively prevent the pressure plate from directly contacting the cable and thus prevent damage to the cable. When the pressure plate is pressed down, the U-shaped limiting plate moves downward with the pressure plate, compressing the second spring. The support sleeve supports the second spring from the outside, limiting the compression length of the second spring and thus limiting the downward movement height of the U-shaped limiting plate. This ensures that the U-shaped limiting plate can properly limit and support the pressure plate, while effectively preventing the pressure plate from directly compressing the second spring beyond its limit and causing damage, thus ensuring the service life of the equipment. During the upward movement of the pressure plate, the second spring rebounds and resets the U-shaped limiting plate to its original position. 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.
[0025] Please see Figures 1-6This utility model provides a technical solution: a damage-resistant crimping fixture, comprising a base plate 1, a pressure plate 2, and a base 3.

The elastic limiting mechanism 6 includes a U-shaped limiting plate 601 and several second springs 602. The second springs 602 are vertically disposed at the bottom of the U-shaped limiting plate 601. A support sleeve 603 is sleeved on the outer wall of the second springs 602 at the bottom of the U-shaped limiting plate 601. A buffer groove 301 matching the U-shaped limiting plate 601 is opened on the top of the base 3. A limiting groove 302 matching the support sleeve 603 is opened on the top of the buffer groove 301 on the inner wall of the base 3.
[0026] Furthermore, a plurality of guide posts 7 are provided between the base plate 1 and the pressure plate 2. The bottom of the guide post 7 is fixedly connected to the top of the base plate 1, and one end of the guide post 7 extends through and above the pressure plate 2. The guide post 7 is slidably connected to the pressure plate 2. The top of the pressure plate 2 is provided with a linear bearing 8 that matches the guide post 7. The linear bearing 8 is slidably sleeved on the outer wall of the guide post 7. A first spring 9 is provided between the base plate 1 and the pressure plate 2. The first spring 9 is sleeved on the outer wall of the guide post 7. The guide post 7 provides guidance between the base plate 1 and the pressure plate 2, which can effectively ensure the stability of the operation of the pressure plate 2. The linear bearing 8 provides sliding support between the pressure plate 2 and the guide post 7, which can effectively ensure the stability and smoothness of the lifting and lowering of the pressure plate 2. The first spring 9 provides elastic support between the pressure plate 2 and the base plate 1, so that the pressure plate 2 automatically rebounds after losing pressure.
[0027] Furthermore, the top two sides of the U-shaped limiting plate 601 are symmetrically provided with support blocks 604, and a first flexible pad 605 is provided between the two support blocks 604. The top of the U-shaped limiting plate 601 is provided with a second flexible pad 606 below the first flexible pad 605. The support blocks 604 support both ends of the first flexible pad 605. The electrical connector passes through the first flexible pad 605 and the second flexible pad 606. The first flexible pad 605 and the second flexible pad 606 provide protection for the cable of the electrical connector, which can effectively enhance the protection effect of the cable and further prevent the cable from being damaged.
[0028] Furthermore, the first flexible pad 605 is provided with a first limiting groove 607 at its bottom, and the second flexible pad 606 is provided with a second limiting groove 608 at its top. The first limiting groove 607 provides a limiting separation above the cable, and the second limiting groove 608 provides a limiting separation below the cable, which can effectively ensure the safety and stability of the cable.
[0029] The working principle of this utility model:
[0030] Refer to the instruction manual appendix Figures 1-6 This utility model, by setting up a base 3, a clamping mechanism 4, a limiting block 5, and an elastic limiting mechanism 6, uses a base plate 1 and a pressure plate 2 to perform a pressing operation on the electrical connector on the top of the base 3. The clamping mechanism 4 is used to clamp and fix the electrical connector on the top of the base 3, which can effectively ensure the safety and stability of the electrical connector during the pressing operation. The limiting block 5 and the elastic limiting mechanism 6 are located on the top of the base 3. The limiting block 5 provides limiting support on one side of the clamping mechanism 4 at the lower pressing limit position of the pressure plate 2 to avoid damage to the electrical connector caused by the pressure plate 2. The elastic limiting mechanism 6 provides limiting support on the other side of the clamping mechanism 4 at the lower pressing limit position of the pressure plate 2 to avoid damage to the electrical connector caused by the pressure plate 2.
[0031] When the elastic limiting mechanism 6 is working, the cable of the electrical connector is placed inside the U-shaped limiting plate 601. The two vertices of the U-shaped limiting plate 601 contact and support the bottom of the pressure plate 2, which can effectively prevent the pressure plate 2 from directly contacting the cable and thus prevent damage to the cable. When the pressure plate 2 is pressed down, the U-shaped limiting plate 601 moves downward along with the pressure plate 2, and the second spring 602 is compressed. The support sleeve 603 supports the second spring 602 from the outside, limiting the compression length of the second spring 602, and thus limiting the downward movement height of the U-shaped limiting plate 601. This ensures that the U-shaped limiting plate 601 can normally limit and support the pressure plate 2, while effectively preventing the pressure plate 2 from directly compressing the second spring 602 beyond its limit and causing damage, thus ensuring the service life of the equipment. During the upward movement of the pressure plate 2, the second spring 602 rebounds and pushes the U-shaped limiting plate 601 back to its original position.
[0032] The buffer groove 301 at the top of the base 3 provides telescopic movement processing for the U-shaped limiting plate 601, and the limiting groove 302 is used to provide limiting support for the support sleeve 603, while also providing telescopic space for the second spring 602.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
