Electrical connecting device for connecting rotor with stator through cable

An electrical connecting device comprising:

• a stator provided by a substantially cylindrical housing;
• a rotor rotatable within said stator;
• a flexible flat cable accommodated in an annular space defined between said rotor and said stator so that one end of said flat cable is fixed on said stator while the other end of said flat cable is fixed on said rotor thereby electrically connecting elements on said rotor to other elements on said stator, said flat cable being wound along the outer periphery of said rotor in one winding direction and wound along the inner periphery of said stator in the opposite winding direction through a bend in said flat cable, the bend forming a boundary between the winding directions;
• and
• a C-shaped movable member in said annular space and defining spaces for accommodating said flat cable between said movable member and the outer periphery of said rotor and between said movable member and the inner periphery of said stator, said C-shaped movable member having a pair of spaced circumferential ends to provide a gap through which said bend in said flat cable passes, whereby said C-shaped movable member rotates relative to said rotor while rotating and to said stator with circumferential movement of said bend caused by winding said flat cable on the outer periphery of said rotor or along the inner periphery of said stator;
• said movable member having a pusher part for pushing said flat cable, said pusher part projecting from an inner edge of one of said pair of circumferential ends of said C-shaped movable member as a relatively thin extension toward the other of said pair of circumferential ends around which said bend in said flat cable is looped
• whereby an opening for passing said flat cable through said gap is defined in part between said other of said pair of circumferential ends and said pusher part, and in part by both said pair of circumferential ends.
