The shielding sheets 2 are installed on the shell 1. The shell 1 is a metal shell. The end of the shell 1 used for plugging with the plug connector is the plug-in end, which is also the plug-in end of the socket connector. Locking pins 6 are also arranged on the left and right sides of the plug-in end.
