Abstract
A rotation-sensored rotary connector includes: a rotary connector for electrically connecting an electrical component installed on a steering to a vehicle-body side; and a rotation sensor for detecting a rotational angle of the steering; wherein the rotation sensor includes a rotor to be directly mounted on a steering shaft, and the rotary connector includes a rotor to be rotated in compliance with the rotor of the rotation sensor, thereby allowing to detect the rotational angle of the steering with an excellent precision.
Claims7
A rotation-sensored rotary connector comprising:
- a rotary connector for electrically connecting an electrical component installed on a steering shaft or a steering wheel to a vehicle-body side;
- and
- a rotation sensor for detecting a rotational angle of the steering shaft;
- a combination switch bracket fixed to a shaft cover;
- a cushioning material at a mounting portion of a stator of the rotation sensor and the combination switch bracket;
- wherein said rotation sensor includes a rotor to be directly fitted on the steering shaft, and said rotary connector includes a rotor to be rotated in compliance with said rotor of said rotation sensor;
- wherein said rotor of said rotation sensor is configured to rotate integrally with the steering shaft;
- wherein said rotor of said rotation sensor comprises a rotor sensing portion and a rotor fixing portion;
- wherein said rotor sensing portion is configured substantially in a ring shape and is provided on an outer periphery of the shaft cover;
- and
- wherein said rotor fixing portion is configured substantially in a stepped cylindrical shape, said rotor fixing portion comprising a reduced diameter portion fitted on the steering shaft such that the rotor fixing portion is rotated integrally with the steering shaft;
- and
- wherein said rotor sensing portion is disposed at a predetermined distance from an outer surface of the reduce diameter portion, the predetermined distance being in a direction away from the steering shaft.
