Specifically, a plurality of connectors are usually mounted on the circuit board 4 inside the server for realizing signal transmission, and the connectors generally include a female end and a male end, wherein for convenience of description, the female end mounted on the circuit board 4 is defined as a fixing member 1, the male end is plugged into the female end, the male end is connected with a cable, and the male end and the cable connected with the male end are defined as a plug connector 2. In the assembly process of a plurality of connectors, the phenomenon that the plug connector 2 is not inserted in place, is not inserted in place or is inserted reversely easily occurs, and the connection state of the connectors directly influences the performance of the server. In the prior art, after all connectors inside a server are assembled, connection states of a plurality of connectors are tested, and plug connectors 2 which are not inserted in place, misplaced or reversely inserted are searched, so that operators can correct the plug connectors 2 which are abnormally connected. After the server is assembled, the connectors are tested, the plug connector 2 with abnormal connection is found out from the connectors according to the test result, and the plug connector 2 with abnormal connection is installed again, so that the assembly efficiency of the server is affected.
