Description

Technical Field

[0001] The utility model relates to the technical field of connector plugging and unplugging, in particular to a circuit connector with smooth plugging and unplugging. Background Art

[0002] In the test adapter, the adapter is connected to the test circuit board through multiple groups of connectors, and the number of pins in each group of connectors usually ranges from dozens to hundreds. During the debugging process, it is often necessary to replace the circuit board for testing multiple times. In order to facilitate the plugging and unplugging of the plugs and sockets on the circuit board, slide rails are usually installed to ensure positioning, and the circuit board is plugged and unplugged manually.

[0003] The traditional plug-in and pull-out device consists only of a slide rail, with two "C"-shaped slide rail openings facing each other, forming the slide grooves on both sides of the circuit board. When manually plugging and unplugging the circuit board, you need to use your body strength to manually insert or pull out the circuit board in the slide rail groove. Since the circuit board has a certain width, and the connection strength of each group of connectors is different, and the number of pins is large, it is easy to cause uneven force during the plug-in and pull-out process, bending and damaging the connector pins, reducing the service life of the connector, and affecting the normal adapter testing work.

[0004] An existing patent (publication number: CN 103384044 A) discloses a connector plugging and unplugging device for testing circuit boards, including a slide rail, which is used for the smooth plugging and unplugging of multiple groups of multi-pin core connectors. The wrench handle has an appropriate length, and the connector is evenly stressed during plugging and unplugging. The plugging and unplugging device of the present invention has a compact structure, low cost, and is easy to operate, which can greatly improve the service life of the connector and the testing efficiency.

[0005] However, the above technical solution still has certain defects. During installation, the wrench needs to be swung to complete the connection, and when pulling, the contact area of ​​the connecting plate is small and cannot be disassembled quickly. Therefore, a circuit connector with smooth plugging and unplugging is proposed. Utility Model Content
