Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to an insertion and extraction force testing device for a pin header connector. Background Art

[0002] Pin headers are a type of connector that are widely used in PCB circuit boards in electronics, electrical appliances, and instruments. They act as a bridge between blocked or isolated circuits within a circuit, taking on the task of current or signal transmission. They are usually used in conjunction with female headers to form a board-to-board connection, or with electronic wiring harness terminals to form a board-to-wire connection. They can also be used independently for board-to-board connection.

[0003] At present, the busbar inspection of pin headers is generally completed manually. During the test, the worker places the busbar on the test equipment, and then performs plug-in and pull-out tests on the pin headers through the test equipment. After the test is completed, the busbar is removed and the subsequent busbar is placed, and the cycle continues. This testing method requires loading and unloading for each busbar, which is very laborious. In addition, the current pin headers are fixed to the drive device of the test equipment by screws. Since the pinhole positions of different busbars are different, the pin headers need to be replaced frequently, and this fixing method makes the replacement of the pin headers very cumbersome.
