Title:
ROTARY CONNECTOR USING IRREGULAR SHAPE ROLLER CURRENT COLLECTOR
Document Type and Number:
Japanese Patent JP2014229601
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that a cylindrical roller current collector may incline for the rotation axis direction as it rotates, and since slip takes place between the roller current collector and the shaft, or between the roller current collector and an outer peripheral member, electrical noise is generated, contact resistance is destabilized, or the product life is shortened.SOLUTION: Outer peripheral shape of a roller current collector is not the conventional cylindrical shape but an irregular shape where the axial center position of the roller current collector is a large diameter part, both ends of the roller current collector are small diameter parts, and the outer peripheral shape is inclining from the large diameter part to the small diameter parts.
