Abstract

The invention relates to a rotary connector, in particular to a rolling type rotary connector which comprises a supporting frame, a rotary shaft rotationally arranged in the supporting frame and a contact assembly arranged between the supporting frame and the rotary shaft. The contact assembly comprises an outer insulating ring arranged on the inner wall of the supporting frame, an outer conducting ring arranged on the inner wall of the outer insulating ring, an inner insulating ring arranged on the outer wall of the rotating shaft and an inner conducting ring arranged on the outer wall of the inner insulating ring, and an elastic ring is nested between the inner wall of the outer conducting ring and the outer wall of the inner conducting ring; and a hole for increasing the elasticity of the elastic ring is formed in the wall body of the elastic ring. The plurality of holes are distributed on the wall body of the elastic ring in the rolling type rotary connector, so that the elasticity of the elastic ring can be increased, the processing difficulty can be reduced, and the contact stability of the elastic ring and the inner and outer conducting rings can be improved on the premise of not changing the wall thickness of the elastic ring.
