Rotary connector
Abstract:
A rotary connector includes a rod-shaped rotating side electrode rotatably supported by an external shell case and a fixed side electrode supported by the external shell case. Rotating side electrode and the fixed side electrode are disposed so that one end parts of the electrodes face each other spaced apart to form a clearance therebetween, the rotary connector further has a cylindrical liquid impregnated member, disposed so as to surround the outer peripheral surface close to the one end part of the fixed side electrode, that covers the clearance formed between the fixed side electrode and the rotating side electrode from outer peripheral sides of the fixed side electrode and the rotating side electrode, and the region formed by one end part of the rotating side electrode, one end part of the fixed side electrode, and the inner peripheral surface of the liquid impregnated member is filled with liquid metal.
