ABSTRACT:
A rotary plug comprises a casing for receiving a cable. Conductive laminates fixed inside the casing are electrically connected to conductors in the cable. A plug with plug body also contain conductive laminates. The plug with its laminates rotates inside the casing. A dual surfaced printed circuit board is installed between the conductive laminates of the plug and those of the cable. A front linear circuit of the dual printed circuit board connects with the conductive laminates of the body of the plug, and a rear circular circuit of the dual printed circuit board contacts the conductive laminates connected to the cable. While the dual printed circuit board rotates along with the body of the plug, the immovable conductive laminates of the cable maintain contact with a point of the rear circular circuit to keep the plug electrically connected to the cable.
