Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to a PCBA anti-collision clamp. Background Technology
[0002] During the production, transportation, and testing processes, PCBA (Printed Circuit Board Assembly) needs to be secured using clamps to prevent displacement or collisions that could cause damage.
[0003] Existing PCBA fixtures have poor impact resistance during use. When subjected to external impact forces, the fixtures are unable to effectively buffer the impact, which can easily lead to collisions between the PCBA and the fixtures, resulting in damage to the electronic components on the PCBA.
[0004] In addition, existing fixtures often do not provide ideal fixation for PCBAs, which can cause the PCBAs to wobble within the fixture and increase the risk of collision damage. Therefore, we propose a PCBA anti-collision fixture to solve the above problems. Utility Model Content

A rectangular groove is opened on the top of the vertical plate, and a rectangular plate is slidably installed in the rectangular groove. The top of the rectangular plate is fixedly installed on the fixture body.
[0009] Preferably, two clamps for fixing the PCBA are slidably installed on the top inner wall of the placement groove, and a rubber protective pad is installed on one side of the clamps.

[0012] Preferably, the driving mechanism includes a threaded hole, a driving screw, and a knob. The threaded hole is formed on the inner walls of both sides of the placement groove. The driving screw is threadedly installed in the threaded hole. One end of the driving screw is rotatably mounted on the clamping plate, and the other end of the driving screw extends to the outside of the clamping body and is fixedly mounted with a knob.

[0015] The beneficial effects of this utility model are:
[0016] 1. By setting a buffer mechanism, when the fixture body is subjected to a downward impact force, the trapezoidal seat will move downward and squeeze the compression seat. The compression seat slides on the support seat, and at the same time, the T-shaped rod will compress the compression spring. The elastic force of the compression spring can effectively buffer the impact force, reduce the collision force on the PCBA, and achieve a good anti-collision effect.
[0017] 2. The guide mechanism can guide the fixture body when it moves up and down, ensuring the stability of the fixture body's movement and preventing it from shifting, which would affect the anti-collision effect and the placement stability of the PCBA.
[0018] 3. The anti-collision chamfer on the placement groove can prevent the PCBA from colliding with the edge of the placement groove when it is placed or taken out, thus providing a certain degree of protection for the PCBA.
[0019] 4. The clamping plate is moved by the drive mechanism, which can clamp and fix the PCBA placed in the placement groove. The rubber protective pad can not only increase the stability of clamping, but also prevent the clamping plate from scratching and damaging the PCBA. Attached Figure Description

Detailed Implementation
[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] This application discloses a PCBA anti-collision fixture.
[0028] Reference Figure 1-5 A PCBA anti-collision fixture includes a support base 101, a fixture body 102 above the support base 101, a placement groove 103 for placing PCBA is provided on the top of the fixture body 102, and an anti-collision chamfer 104 is provided on the placement groove 103. The anti-collision chamfer 104 can effectively prevent the PCBA from colliding with the edge of the placement groove 103 during placement and removal.
[0029] In this embodiment, the top of the support base 101 is provided with a guide mechanism connected to the clamp body 102. The guide mechanism includes a vertical plate 201, a rectangular groove 202, and a rectangular plate 203. Two vertical plates 201 are fixedly installed on the top of the support base 101. A rectangular groove 202 is opened on the top of the vertical plate 201. The rectangular plate 203 is slidably installed in the rectangular groove 202, and the top end of the rectangular plate 203 is fixedly installed on the clamp body 102. When the clamp body 102 is subjected to force and moves up and down, the rectangular plate 203 slides in the rectangular groove 202, providing guidance for the movement of the clamp body 102 and ensuring its stability.
[0030] In this embodiment, a buffer mechanism for collision prevention is provided between the support base 101 and the clamp body 102. The buffer mechanism includes a trapezoidal base 301, a pressing base 302, a connecting plate 303, a T-shaped rod 304, and a compression spring 305. Two trapezoidal bases 301 are installed at the bottom of the clamp body 102, and two pressing bases 302 are slidably installed at the top of the support base 101. The pressing bases 302 are adapted to the trapezoidal bases 301. Multiple T-shaped rods 304 are fixedly installed on one side of the trapezoidal bases 301, and the T-shaped rods 304 pass through the corresponding connecting plate 303. Multiple compression springs 305 are fixedly installed between the trapezoidal bases 301 and the connecting plate 303. A limiting groove 403 is formed at the bottom of the support base 101, and a limiting base 404 is installed at the bottom of the pressing base 302. The limiting base 404 is slidably connected to the corresponding limiting groove 403. The cooperation between the limiting groove 403 and the limiting base 404 limits the sliding of the pressing base 302. When the fixture body 102 is subjected to a downward impact force, the trapezoidal seat 301 moves down and squeezes the compression seat 302. The compression seat 302 slides on the support seat 101, and the T-shaped rod 304 compresses the compression spring 305. The elastic force of the compression spring 305 reacts to the trapezoidal seat 301, thereby buffering the impact force and reducing the collisions suffered by the PCBA.
[0031] In this embodiment, two clamping plates 401 for fixing the PCBA are slidably installed on the top inner wall of the placement groove 103. A rubber protective pad 402 is installed on one side of the clamping plate 401. The rubber protective pad 402 can prevent damage to the PCBA when the clamping plate 401 is clamped, and at the same time increase the friction and improve the fixing effect. A limiting groove 403 is formed on the bottom inner wall of the placement groove 103. A limiting seat 404 is fixedly installed on the bottom of the clamping plate 401, and the limiting seat 404 is slidably connected to the corresponding limiting groove 403 to limit the movement of the clamping plate 401.
[0032] In this embodiment, a driving mechanism is provided on both inner walls of the placement groove 103. The driving mechanism is connected to the clamping plate 401. The driving mechanism includes a threaded hole 501, a driving screw 502, and a knob 503. The threaded hole 501 is formed on both inner walls of the placement groove 103. The driving screw 502 is threadedly installed in the threaded hole 501. One end of the driving screw 502 is rotatably mounted on the clamping plate 401, and the other end of the driving screw 502 extends to the outside of the clamping body 102 and is fixedly mounted on the knob 503. A rotating groove is formed on the other side of the clamping plate 401. An annular groove is formed on the inner wall of the rotating groove. An annular seat is installed on the driving screw 502, and the annular seat is rotatably connected to the annular groove to ensure that the driving screw 502 can drive the clamping plate 401 to move without rotating itself with the clamping plate 401. Rotating the knob 503 drives the screw 502 to rotate within the threaded hole 501, thereby pushing the clamping plate 401 to slide within the placement groove 103, thus clamping or releasing the PCBA.
[0033] In this utility model, when in use, the PCBA is placed in the placement groove 103, the knob 503 is turned to drive the screw 502 to rotate and push the clamp 401 to move toward the PCBA until the rubber protective pad 402 is in close contact with the PCBA, thus completing the fixation of the PCBA.
[0034] When the fixture is subjected to external impact, the fixture body 102 moves downward, the rectangular plate 203 slides in the rectangular groove 202 for guidance, and at the same time, the trapezoidal seat 301 squeezes the compression seat 302, the compression seat 302 slides on the support seat 101, the T-shaped rod 304 compresses the compression spring 305, the elastic force of the compression spring 305 buffers the impact force, reduces the collision force on the PCBA, and plays a role in anti-collision protection.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
