[0002] The electromagnetic compatibility test fixture is mainly used to fix the device or system under test during the electromagnetic compatibility test to ensure the accuracy and reliability of the test. This device usually needs to be customized according to the specific test requirements and the characteristics of the device under test.

[0003] At present, in the existing technology, most of the electromagnetic compatibility test fixtures fix the antenna for detection by rotating the threaded rod. When a large number of antennas need to be tested, the method of rotating the threaded rod is too slow, and the workers' hands will be seriously worn out if they rotate the threaded rod for a long time. In view of this, we propose an electromagnetic compatibility test fixture. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides an electromagnetic compatibility test fixture, which has the following beneficial effects:

[0014] (1) The electromagnetic compatibility test fixture has a pressure plate. When the antenna needs to be tested, the antenna presses the pressure plate, causing the pressure plate to move downward, so that the pressure plate pushes the hydraulic device through the hinged rod, and the hydraulic device pushes the elastic telescopic rod so that the clamp fixes the antenna.

[0015] (2) The electromagnetic compatibility test fixture has an extrusion block. When the sliding plate squeezes the switch, the motor starts and drives the fixture to rotate. When the extension rod squeezes the surface of the extrusion block, the block is retracted, so that the spring push plate moves upward, releasing the sliding plate from squeezing the switch, thereby turning off the motor, and the pressure plate pushes out the antenna, releasing the clamping claw from fixing the antenna, so that the worker can quickly replace the antenna.
