Description

[0001] This utility model relates to the field of electronic component testing technology, specifically to an auxiliary clamping fixture for electronic components. Background Technology

[0002] Auxiliary clamping fixtures for electronic component testing, or simply clamping fixtures, are auxiliary tools used to stably hold the components under test during the testing process. These fixtures are designed to ensure that electronic components remain fixed during testing, thereby improving the accuracy and reliability of the testing. Auxiliary clamping fixtures for electronic component testing are widely used in the testing of various electronic components; circuit boards are also typically required to be fixed in place during testing.

[0003] Existing clamping fixtures are not easy to adjust according to the size of the circuit board, and have low stability during clamping, making them prone to displacement. Therefore, we propose an auxiliary clamping fixture for electronic components to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary clamping fixture for electronic components, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the existing clamping fixture according to the size of the circuit board, low stability during clamping, and easy deviation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamping fixture for electronic components, including a testing rack;

[0012] Preferably, the inner lower surface of the clamping plate is provided with an anti-slip pad, and the corners of the circuit board rest against the surface of the anti-slip pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting a sliding groove around the surface of the test frame, and setting a screw structure inside the sliding groove, the clamping plate is installed on the screw structure to drive the clamping plate to open and close. The shape of the clamping plate can be locked onto the corner of the circuit board, thereby locking and fixing the circuit board. The screw and the clamping plate operate independently, and the position of the corresponding clamping plate can be adjusted according to the circuit board of different sizes, so that the clamping plate fits against the corner of the circuit board.
