Rotary connector for connecting cables

摘要

A rotary connector configured so as to enable extension or contraction of a cable transmitting electrical signals etc. by connecting a spirally wound flat cable between two cable parts and making the spirally wound flat cable wind or unwind using a rotary body and a fixed body, more particularly a rotary connector able to protect the flat cable from fusing when an overcurrent flows. The plus side connection portion of connection portions between conductors of a flat cable and an outer conductor (cable) electrically connects the conductors of the flat cable and the outer conductor through members having a fuse function. When a short-circuit occurs in the circuit including the flat cable and the outer conductor, the member having a fuse function fuses first so as to prevent the flat cable from heating and fusing.
