Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for temporarily fixing a rotor and a stator, which constitute a roll connector as an electrical connecting device between a steering wheel for a vehicle and a steering column, at a neutral position of a coil tape housed therein. To a temporary fixing device for a roll connector.

[0002]

2. Description of the Related Art Conventionally, a roll connector has been generally used as a device for electrically connecting a steering wheel and a steering column of an automobile. No. 77892.

As shown in FIG. 10, in this roll connector temporary fixing device, a rotor 72 of a roll connector 70 is provided.
In order to keep the coil tape housed inside and the stator 74 in a spiraled state in a neutral position (a state in which the coil tape is not overtightened or loosened), the rotor 72 serves as an engaging means for the temporary fixing pin 76. A rotation stopper 78 is formed on the stator 74, and a pin holding portion 80 is formed on the stator 74.

The temporary fixing pin 76 is inserted into the pin holding portion 80. At this time, the insertion stopper 76A formed on the back surface of the temporary fixing pin 76 abuts the upper surface 72A of the rotor 72, so that the temporary fixing pin 76 moves. Positioning in the insertion direction is performed. Further, the insertion stopper 76A is provided on the upper surface 7 of the rotor 72.
It is sandwiched by a pair of rotation stoppers 78 formed in 2A, and the rotor 72 is positioned in the rotation direction.

[0005]

However, in the roll connector temporary fixing device, when the roll connector 70 is completely attached to the vehicle, the temporary fixing pin 76 is pulled out from the pin holding portion 80. A dustproof cap 84 is attached to the connector 82 connected to the rotor 72. The dustproof cap 84 is also removed when the roll connector 70 is completely attached to the vehicle. Therefore, in this temporary fixing device for the roll connector, there is a problem that the number of parts is increased and the cost is increased due to the parts to be removed when the installation to the vehicle is completed.

In view of the above facts, an object of the present invention is to obtain a roll connector temporary fixing device capable of reducing the number of parts and suppressing an increase in cost.

[0007]

A temporary fixing part that engages with both the engaging part and the stator-side engaging part and temporarily fixes and fixes the rotor and the stator at a neutral position, and a temporary cap part that serves as a dustproof cap of the wiring connector. It is characterized by having a locking pin.

According to a second aspect of the present invention, there is provided a roll connector temporary fixing device in which the rotor and the stator are connected by a roll connector having a wiring connector and a stator rotatably holding the rotor. A roll connector temporary fixing device for temporarily fixing each other, wherein the stator and the rotor are temporarily fixed to a neutral position, and at least one of the stator and the rotor has an opening of the wiring connector. It is characterized in that a fixing means for fixing the wiring connector is provided at a closed position.

[0009]

In the temporary fixing device for the roll connector according to the present invention as set forth in claim 1, until the roll connector is attached to the vehicle,
By engaging the temporary fixing portion of the temporary fixing pin with both the rotor-side engaging portion and the stator-side engaging portion, the rotor and the stator can be temporarily fixed at the neutral position. Further, by engaging the wiring connector connected to the rotor with the cap portion of the temporary fixing pin, it is possible to protect the wiring connector from dust.

Therefore, the temporary fixing pin and the dustproof cap of the wiring connector are manufactured separately from each other, and the temporary fixing pin and the dustproof cap are different from those of the conventional temporary fixing device of the roll connector which is detached after mounting on the vehicle. By integrating, the number of parts can be reduced and the cost increase can be suppressed.

According to a second aspect of the present invention, in the roll connector temporary fixing device, the stator and the rotor are temporarily fixed to the neutral position by the fixing means and the stator and the rotor are fixed until the roll connector is attached to the vehicle. The wiring connector is fixed to at least one of the positions where the opening of the wiring connector is closed.

Therefore, both the temporary fixing pin and the dustproof cap of the wiring connector used in the conventional temporary fixing device of the roll connector can be eliminated, and the number of parts can be reduced and the cost increase can be suppressed. .
