ABSTRACT:
A rotary connector which uses two flat cables and simplifies a process of connecting both the flat cables to a lead block. In this rotary connector, a through hole and a pair of window holes are formed in a supporting element of an outer lead block. Left-hand side and right-hand side groups of a plurality of joint bars are exposed in the window holes. Necessary first and second flat cables are preliminarily connected to one another into a flat cable. Further, each of conductors placed near this flat cable is exposed. Furthermore, the exposed portion of each of the conductors is made to overlap with the exposed portion of a corresponding one of joint bars, which are exposed in both the window holes of the outer lead block. The conductors are connected to the joint bars at two connection portions placed in a direction, in which the conductors extend, by ultrasonic-welding or spot-welding. Subsequently, the conductors exposed to the through hole are cut and divided into those connected to the two flat cables and that are electrically independent of each other.
