[0005] The purpose of this invention is to provide a PCB test fixture that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A PCB test fixture includes a frame with multiple partitions inside, dividing the interior of the frame into several clamping slots. Clamping plates are installed inside the clamping slots, and screws are rotatably mounted inside the frame, with each clamping plate threaded onto the screw.

[0008] As can be seen, by turning the screw to move several clamping plates simultaneously, and with the help of the inner wall of one side of the frame and multiple partitions, the PCB can be clamped and fixed in the clamping slot. After the test, simply turn the screw in the opposite direction to move the clamping plates in the opposite direction to release the PCB, making it easy to remove quickly without causing any additional damage to the PCB.

[0009] Furthermore, parallel positioning notches are provided on one side of the inner wall of the clamping groove and on the surface of the clamping plate.

[0010] Furthermore, positioning notches are equipped with positioning corner blocks.

[0011] Furthermore, multiple adjustment holes are provided on the upper surfaces of the frame, partitions, and clamps, and the positioning corner blocks are installed on the adjustment holes by fixing bolts.

[0012] Furthermore, the inner walls on both sides of the clamping groove are provided with sliding grooves, and the sliding grooves are provided with sliders, the ends of which are connected to the clamping plate.

[0013] Furthermore, a first bearing and a second bearing are respectively installed on both sides of the frame along its length, and the two sides of the screw are respectively installed inside the first bearing and the second bearing.

[0014] Furthermore, both the partition and the clamping plate have clearance holes inside for the screw to pass through, and the diameter of the clearance holes is larger than the diameter of the screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a screw to move several clamping plates simultaneously. With the help of the inner wall of one side of the frame and multiple partitions, the PCB can be clamped and fixed in the clamping slot. After the test, simply turn the screw in the opposite direction to move the clamping plates in the opposite direction to release the PCB, making it easy to remove quickly without causing any additional damage to the PCB.

[0017] 2. By setting up positioning corner blocks, this utility model can position one side of the PCB when placing it, thereby ensuring the accuracy of the PCB's position. Furthermore, the number and position of the positioning corner blocks can be adjusted arbitrarily, making it suitable for testing and fixing PCBs of different sizes.

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] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a PCB test fixture, including a frame 1. The frame 1 has multiple partitions 101 inside, which divide the interior of the frame 1 into several clamping slots 102. Clamping plates 103 are provided inside the clamping slots 102. Screws 104 are rotatably mounted inside the frame 1, and the clamping plates 103 are threaded onto the screws 104.

[0027] By placing the PCB in the clamping slot 102 and then turning the screw 104, several clamping plates 103 move simultaneously under the action of the threaded connection. Therefore, in conjunction with the inner wall of one side of the frame 1 and multiple partitions 101, the PCB can be clamped and fixed in the clamping slot 102. After the test, simply turn the screw 104 in the opposite direction to move the clamping plates 103 in the opposite direction to release the PCB, making it easy to remove quickly without causing additional damage to the PCB.

[0028] Preferably, the inner wall of one side of the clamping groove 102 and the surface of the clamping plate 103 are provided with mutually parallel positioning notches 2.

[0029] By placing the two sides of the PCB within the corresponding two positioning notches 2, a supporting function can be provided, ensuring that all PCBs are at the same height and preventing the solder joints or electronic components on the back of the PCB from being squeezed or bumped.

[0030] Preferably, a positioning corner block 3 is provided on the positioning notch 2.

[0031] When placing the PCB, first place its two sides into the corresponding two positioning notches 2, then slide the PCB so that one side abuts against the positioning corner block 3, which can play a positioning role. Then, turn the screw 104 to drive the clamping plate 103 to move and clamp and fix the PCB, thus ensuring the accuracy of all PCB positions.

[0032] Preferably, the upper surfaces of the frame 1, partition 101 and clamping plate 103 are provided with multiple adjustment holes 301, and the positioning corner block 3 is installed on the adjustment holes 301 by fixing bolts 302.

[0033] By adjusting the hole 301 and fixing bolt 302, the number and position of the positioning corner blocks 3 can be adjusted arbitrarily, thus making it suitable for PCB testing and fixing of different sizes. This broadens the application range and eliminates the need to prepare multiple different fixtures for replacement, reducing usage costs.

[0034] Preferably, both sides of the inner wall of the clamping groove 102 are provided with sliding grooves 4, and the sliding grooves 4 are provided with sliders 401, and the end of the sliders 401 is connected to the clamping plate 103.

[0035] The limiting effect of the slide groove 4 and the slider 401 on the clamping plate 103 ensures that the clamping plate 103 can move horizontally under the drive of the screw 104 to clamp the PCB.

[0036] Preferably, a first bearing 5 and a second bearing 501 are respectively installed on both sides of the frame 1 along its length, and the two sides of the screw 104 are respectively installed in the first bearing 5 and the second bearing 501.

[0037] By setting the first bearing 5 and the second bearing 501, the resistance when the screw 104 rotates is reduced, which makes it easier and smoother to drive the clamping plate 103 to clamp the PCB.

[0038] Preferably, both the partition plate 101 and the clamping plate 103 have clearance holes 6 for the screw 104 to pass through, and the diameter of the clearance holes 6 is larger than the diameter of the screw 104.

[0039] The screw 104 passes through the interior of the relief hole 6 without contacting it, thus avoiding any impact on the rotation operation of the screw 104.
