Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle for connecting an electric circuit such as a horn installed on a rotating vehicle handle and an electric circuit installed on a non-rotating body. The present invention relates to the structure of the electrical connector of the handle portion for the vehicle.

[Prior Art] Conventionally, a horn switch installed on a rotating handle of a vehicle has a slip ring on a rotating handle and a contact on a non-rotating body side as disclosed in, for example, Japanese Utility Model Laid-Open No. 61-30557. An electric circuit is connected by arranging the pieces. The contact piece is biased by the coil spring and is inserted into the cylindrical body and the case body.

Further, conventionally, a canceling mechanism of a turn signal switch of an automobile, for example, as disclosed in Japanese Utility Model Publication No. 56-30522, a cancel cam body having a steering shaft and an upper end coupled to a steering wheel, This is due to a cancel ratchet or the like that operates when the lever is operated. The cancel cam body is biased upward by a spring and is coupled to the handle.

[Problems to be Solved by the Invention] The connection structure of the handle portion in the above-described conventional horn circuit is a structure in which the contact piece is inserted into the case body and the cylinder body and is urged by the coil spring from below.
For this reason, the number of parts is large, which causes a high cost.

Further, in the above-described conventional cancel mechanism of the turn signal switch, a coil spring for pressing the cancel cam body is indispensable in addition to the coil spring for urging the contact piece. Therefore, at least two or more coil springs are conventionally disposed in the handle portion of the automobile, and there is a problem that the number of coil springs and the number of assembling steps are large.

[Means for Solving Problems] The structure of the electric connector of the vehicle handle portion according to the present invention is as follows.
Vehicle having a slip ring fixed to a rotating handle, a terminal installed on a non-rotating body, and a cancel cam body inserted into a steering shaft and a turn signal switch body having an upper end connected to the handle By disposing a connector in which a sliding contact portion that comes into contact with the slip ring and a coil spring portion that comes into contact with the terminal and biases the cancel cam body upward are integrally formed in the handle portion for use The problems existing in the above-mentioned conventional technique are solved.

[Operation] The connector integrally includes the sliding contact portion that comes into contact with the slip ring of the handle and the coil spring portion that comes into contact with the terminal provided on the non-rotating body and biases the cancel cam body upward. Is forming. Therefore, the connector also serves as a contact that makes sliding contact with the slip ring and as a coil spring, and can contribute to a reduction in the number of parts and the number of assembly steps.

[Embodiment] Hereinafter, the structure of the electrical connector of the vehicle handle portion according to the present invention will be described in detail with reference to FIGS. 1 and 2.

Reference numeral 1 is a handle fixed to the upper end of the steering shaft 2, and a slip ring 3 is fixed to the lower surface thereof.
The slip ring 3 is connected to a switch provided on the steering shaft 2 such as a horn switch, for example. The slip ring 3 is a member made of a ring-shaped conductive plate member. Reference numeral 4 denotes a cancel cam body, the engaging portion 4a of the upper end of which is engaged with the handle 1 and the lower end of which is pressed by the coil spring portion 5a of the connector 5. The cancel cam body 4 rotates in the same direction as the steering wheel 1 and the steering shaft 2. Reference numeral 4b is a cancel rib for hitting a canceling ratchet (not shown) for automatically returning the operating lever 6a of the turn signal switch body 6. The connector 5 is a coil spring portion 5a.
And a sliding contact portion 5b, the upper sliding contact portion 5b is in contact with the slip ring 3 and the lower coil spring portion 5a is in contact with the terminal 7. The connector 5 is held by interposing a central portion between the guide tube 6b of the turn signal switch body and the cancel cam body 4. The lower end of the coil spring portion 5a is pressed against the terminal 7, and the cancel cam body 4 is pressed upward by the upper portion. The sliding contact portion 5b is a bar-shaped spring member,
The portion contacting the slip ring 3 is curved. The terminal 7 is fixed to the base 6c of the turn signal switch body 6. Reference numeral 8 is a harness connected to the terminal 7.

The structure of the electric connector of the vehicle handle portion according to the present invention is
The configuration is as described above, and the operation will be described in detail below.

For example, when the horn switch arranged on the handle 1 is turned on, the energizing current is supplied from the power source (not shown) to the harness 8,
It flows through the terminal 7, the connector 5, and the slip ring 3 to the horn switch. The connector 5 has a function of electrically connecting the terminal 7 which is a non-rotating body and the slip ring 3 fixed to the rotating handle 1. The coil spring portion 5a of the connector 5 is interposed between the cancel cam body 4 and the terminal 7 to urge the cancel cam body 4 upward so that the engaging portion 4a is press-fitted to the handle 1. ing. In this way, the connector 5 integrally forms the sliding contact portion 5b having a function of a contact slidingly contacting the slip ring 3 and the coil spring portion 5a having a function of a spring for pressing the cancel cam body 4. . Therefore, the number of parts and the number of assembling steps can be reduced.

[Effect of the Invention] The structure of the electric connector of the vehicle handle portion according to the present invention is as follows.
Since the sliding contact portion that comes into contact with the slip ring and the terminal that comes into contact with the terminal and the coil spring portion for biasing the cancel cam body upward are integrally formed,
The number of parts and the number of assembly steps can be reduced.
