A concave plug-in cavity 2 is provided at the front end of the plug connector 1, and a bearing column 3 is provided at the rear end of the plug connector 1. The bearing column 3 is a cylindrical structure, and the bearing column 3 is coaxially arranged with the plug connector 1. A positioning groove 4 is provided on the outer surface of the bearing column 3, and the positioning groove 4 is arranged along the front-to-back direction. The positioning groove 4 is V-shaped, and there are five positioning grooves 4. The five positioning grooves 4 are arranged at circumferential intervals on the bearing column 3. A plug-in hole 5 corresponding to the positioning groove 4 is provided at the bottom of the plug-in cavity 2, and the plug-in hole 5 passes through the rear end of the plug connector 1, and the plug-in hole 5 is connected to the positioning groove 4 accordingly.
