Abstract
The present invention provides a freely rotatable electrical conduction structure including at least two cylindrical electrical conduction portions, an insulated material portion and at least two electrical conduction terminals. The at least two cylindrical electrical conduction portions are arranged separately along an axis, wherein the inner surface of each cylindrical electrical conduction portion is welded with an end of a conducting wire. The insulated material portion is combined with the at least two cylindrical electrical conduction portions via injection molding to form a circular shaft assembly. The at least two electrical conduction terminals correspond to the at least two cylindrical electrical conduction portions respectively, and each electrical conduction terminal partially projects to form an arc contact portion configured to abut onto the outer peripheral surface of its corresponding cylindrical electrical conduction portion. Each electrical conduction terminal is allowed to rotate around its corresponding cylindrical electrical conduction portion with its arc contact portion keeping contacting and conducting with the outer peripheral surface.
