Claims
- 1. A flat cable connector comprising:
- a stator;
- a rotor rotably mounted on said stator;
- a flat cable spirally accommodated in an annular space defined between the stator and the rotor, one end of the flat cable being fixed to said rotor and the other end thereof being fixed to said stator;
- an inner gear having an axis thereof of an axis of said rotor and formed on said stator;
- an outer gear coaxial with said inner gear and having the same module as said inner gear and having a smaller diameter than said inner gear;
- a planetary gear having a first gear engaging said inner gear and said outer gear and a second gear coaxial with said first gear;
- a ring having an inner gear engaging said second gear and rotatably mounted on said stator; and
- indicating means for indicating the rotational position of said rotor, the indicating means being mounted on said ring and said stator.
- 2. The flat cable connector as defined in claim 1, wherein said first gear and said second gear have the same module and pitch diameter so that said planetary gear comprises one gear, and said inner gear of said ring and said inner gear of said stator are slightly varied from each other in the pitch diameter or the module thereof so that the number of the teeth of said inner gears are differentiated from each other.
- 3. The flat cable connector as defined in claim 1, wherein a guide roller revolving around said rotor together with said planetary gear is mounted on said planetary gear; and said flat cable is fixed to said stator by being wound around said guide roller in a length of approximately half the circumference of said guide roller in the direction opposite to the direction in which said flat cable is wound around said rotor.
- 4. The flat cable connector as defined in claim 3, further comprising first stop means and second stop means cooperating with each other to restrict the rotation of said ring to a predetermined range, the first and second stop means being formed on said stator and said ring, respectively.
