A connector includes an insulated housing, four connecting terminals, three pins and a plug. The insulated housing has a containing space and a disposing surface, and the disposing surface is located in the containing space. The connecting terminals are separately disposed in the containing space of the insulated housing and located on the disposing surface. The pins are separately disposed in the containing space of the insulated housing and extend from the disposing surface toward a direction away from the disposing surface, and the connecting terminals surround the pins. The plug is disposed in a center of the containing space of the insulated housing and located on the disposing surface. The plug is beneficial to rotate and has no directionality. The plug includes a plurality of conductive rings, the conductive rings are separately arranged along the direction away from the disposing surface, and the pins surround the plug.

A terminal assembly includes an insulating support member including first and second arrays of apertures, each aperture extending from an upper surface of the insulating support member to an opposite lower surface of the insulating support member.
