Technical Field

[0001] The utility model relates to the technical field of wireless communication modules, in particular to a test fixture for wireless communication modules. Background Art

[0002] A wireless communication module, also known as a wireless network card, is a terminal wireless network device. Compared with wired communication, it has better and wider adaptability and is almost not restricted by the geographical environment. During the production process of wireless network cards, various functions need to be detected to ensure the production quality.

[0003] For example, patent number CN220626454U discloses an automatic detection device for wireless communication modules, including a machine body and a clamping component. A motor is provided on the left side of the machine body, a lead screw is rotatably connected inside the top of the machine body, and the output shaft of the motor rotatably penetrates the machine body and is fixedly connected to the lead screw. The clamping component is arranged on the top of the machine body for clamping the tested wireless network card. When the output shaft of the air cylinder retracts, the fixing plate moves towards one end close to the air cylinder. When the fixing plate moves, the clamping rods are driven to rotate through the connecting rods on both sides and approach each other, and the clamping blocks are driven to approach each other. The wireless network card to be tested is placed on the pressing plate on the top of the two clamping blocks, and the second spring confines it within the clamping blocks. The air cylinder continues to work until the wireless network card is clamped. There is no need to replace different fixtures to clamp wireless network cards of different sizes. The fixation is simple and the fixture can be adjusted according to the size of the wireless network card. However, the test fixture for wireless communication modules in this patent requires manually placing the wireless network card between the clamping blocks, resulting in troublesome loading and unloading, low efficiency, and lacking an automatic centering and limiting function for the wireless network card, which easily causes the wireless network card to shift and tilt during placement, affecting the subsequent detection.
