[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0016] EMBODIMENT

[0017] In order to solve the above technical problems, the present embodiment provides a fixing device of a conduction test equipment, as shown in Figures 1-2As shown, the device includes a base 20 mounted on a workbench 10 and a support fixture 30 mounted on one side of the base 20 for placing the product under test. A pressure block 40 is hinged to the side of the base 20 near the support fixture 30. A drive assembly 50 is mounted on the base 20. After the product under test is placed on the support fixture 30, the product under test is connected to the testing instrument. Then, the drive assembly 50 drives the pressure block 40 to press down and fix the product under test on the support fixture 30, thereby avoiding inaccurate test results due to shaking or displacement of the product under test during the test. After the test is completed, the drive assembly 50 drives the pressure block 40 to release the product under test, thereby removing the product under test, which facilitates the test operation and improves the test efficiency.

[0018] Furthermore, the base 20 is fixed to the workbench 10 by screws. A fixing block 21 is provided on the base 20, and a mounting seat 22 is provided on one side of the fixing block 21. For example, the pressure block 40 is L-shaped. One end of the pressure block 40 is connected to the driving end of the driving assembly 50, and the other end of the pressure block 40 forms a pressing part 21 extending above the support fixture 30. The middle of both ends of the pressure block 40 is hinged to the mounting seat 22. Then, the driving assembly 50 acts on one end of the pressure block 40, causing the pressure block 40 to rotate on the mounting seat 22, thereby causing the pressing part 21 of the pressure block 40 to press down on the top of the product to be tested, so that the product to be tested is fixed on the support fixture 30.

[0019] Furthermore, the drive assembly 50 includes a driver 52 disposed above the fixed block 21 and a connecting block 51 disposed at the driving end of the driver 52, the connecting block 51 being hinged to one end of the pressure block 40. For example, the driver 52 is a pneumatically controlled cylinder, the telescopic end of which is connected to one end of the connecting block 51, and the other end of the connecting block 51 is connected to the end of the pressure block 40 via a rotating shaft, thereby causing the pressure block 40 to rotate on the connecting block 51, allowing the pressure block 40 to press or release the product to be tested on the carrying fixture 30.

[0020] Furthermore, it also includes an adjusting rod 23 that can be movably mounted on the fixed block 21, with the mounting base 22 fixed to the end of the adjusting rod 23. The adjusting rod 23 can be adjusted in position on the fixed block 21, allowing the mounting base 22 and the pressure block 40 to be adjusted in the horizontal direction, thereby adjusting the position of the pressure block 40 above the support fixture 30, and further adjusting the position of the pressure block 40 pressing down on the product under test. This allows for adaptive adjustment according to the structure of the product under test, improving compatibility.

[0021] In the above solution, in order to avoid the pressure block 40 embossing the surface of the product to be tested, a silicone sleeve is fitted on the pressing part 21 of the pressure block 40, so that the silicone sleeve contacts the surface of the product to be tested, thereby avoiding damage to the product surface and also achieving the effect of insulation.

[0022] In this embodiment, the product under test is taken as an electric vehicle charger, but it is not limited to chargers. Figures 2-3 As shown, the top and one side of the support fixture 30 are open. During testing, the charger is pushed into the support fixture 30 from one of the open sides, and then the pressure block 40 located above the support fixture 30 presses down to fix the charger. Furthermore, during testing, the charger needs to be connected to the testing instrument for power supply testing. To meet the testing requirements, the fixing device needs to be insulated from the product under test. The support fixture 30 is made of non-conductive materials such as insulating plastic to provide insulation. Simultaneously, the pressure block 40, adjusting rod 23, connecting block 51, fixing block 21, and base 20 in this design can all be made of non-conductive materials such as plastic to avoid affecting the test results. Fixing the product under test does not require a large pressure; therefore, using non-metallic materials can also meet the strength requirements.

[0023] Furthermore, the bottom of the support fixture 30 has several through slots 31 to facilitate heat dissipation for the charger. Additionally, clearance slots 32 are provided on both sides of the support fixture 30, allowing the wires at both ends of the charger to pass through and be protected when the charger is pushed into the support fixture 30. When testing other products, a support fixture 30 adapted to that product can be used.

[0024] In summary, the solution of this application sets a base on the workbench, and a support fixture for placing the product under test is set on one side of the base. A pressure block is hinged on the side of the base near the support fixture, and a drive assembly is set on the base. After the product under test is placed on the support fixture, the product under test is connected to the testing instrument. Then, the drive assembly drives the pressure block to press down and fix the product under test on the support fixture, thereby avoiding the problem of inaccurate test results due to shaking or displacement of the product under test during the test. After the test is completed, the drive assembly drives the pressure block to release the product under test, thereby removing the product under test, which facilitates the test operation and improves the test efficiency.

[0025] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
