The testing cost of the terminal wire is high, and when there are multiple terminal wires, the connectors of terminal wires of different specifications do not match the sockets of the charging head, and there are tolerances. To this end, the applicant has made improvements and proposed a plug structure of a test fixture, aiming to solve the plug-in and unplug tolerance problems of different terminals.
