Abstract
A rotor interlocked with a steering wheel is rotatably connected with a stator fastened to a steering column, a flat cable is provided in a coiled position in an annular hollow space formed by the stator and a rotor, and an inner peripheral end of the flat cable is electrically connected with an external cable through a connector which is provided in and projects from the rotor. On the upper wall of the rotor, which forms an inner cylinder and an upper wall of the annular hollow space, a bus bar is connected with each conductor on the inner peripheral end of the flat cable and is scored to the rotor with an insert mold, and each conductor of the flat cable and an external cable are welded to the bus bar.
Claims13
A cable reel comprising:
- a rotor interlocked with a steering wheel and rotatably connected to a stator provided on a steering column, a flat cable provided in a coiled condition in an annular hollow space formed by said stator and said rotor, said flat cable having an inner peripheral end electrically connected with an external cable through a connector extending from said rotor;
- and
- an upper wall of said rotor forming an upper wall of said annular hollow space, a bus bar connected with each conductor on said inner peripheral end of said flat cable and secured to said upper wall of said rotor within an insert mold, and said conductors of said flat cable and an external cable being welded to said bus bar.
A cable reel comprising:
- a stator;
- a rotor rotatably connected to said stator;
- a flat cable provided in a coiled condition in an annular hollow space formed by said stator and said rotor, said flat cable having an inner peripheral end electrically connected with an external cable through a connector extending from said rotor;
- and
- an upper wall of said rotor forming an upper wall of said annular hollow space, a bus bar connected with each conductor on said inner peripheral end of said flat cable and insert molded to said upper wall of said rotor and said conductors of said flat cable and an external cable being welded to said bus bar.
A method of making a cable reel comprising:
- providing a rotor rotatably connected to a stator, said rotor and said stator forming an annular hollow space, and an upper wall of said rotor forming an upper wall of said annular hollow space;
- providing a flat cable in a coiled condition in said annular hollow space formed by said stator and said rotor, said flat cable having an inner peripheral end;
- insert molding a bus bar to said upper wall of said rotor;
- and
- welding said bus bar to each conductor on said inner peripheral end of said flat cable.
