[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energizing device used for transmitting and receiving electric signals between a steering column having a finite number of revolutions and a steering column, such as a steering device for a vehicle having an airbag. The present invention relates to a temporary fixing structure.

[0002]

2. Description of the Related Art Conventionally, there are various types of electrical connection devices between a steering wheel provided with an airbag and a steering column, but all of them have a temporary fixing means for maintaining a neutral position between the steering wheel and the steering column. is necessary. As a simple structure of the temporary fixing means, there is, for example, a structure described in Japanese Utility Model Laid-Open No. 2-41389, which is provided with a tongue on the stator side (fixed side) and a rotor side (rotational side). The side) requires an engagement hole or an engagement projection into which the tongue-shaped body fits.

[0003]

However, in the above-mentioned conventional product, it is necessary to provide an additional material on both the stator side and the rotor side or to perform processing, and the tongue is formed of resin integrally with the stator. Because of this, it was not very realistic, for example, it could be broken at the time of temporary fixing.

[0004]

The present invention is a further simplification of the conventional product, and utilizes a cable with a connector on a fixed case side or a rotating side provided in an energizing device for a vehicle airbag. However, the above problem is solved by temporarily fixing the cord to a clamp provided on the side opposite to the cord mounting side. That is, in the present invention, a spiral cord-shaped cord (1) is attached to the steering column side so as to follow the turning operation of the steering wheel, and a fixed case (2) that does not rotate is attached to the steering column side. In a vehicle airbag energizing device housed in a body (8) formed of a rotating part (3) attached and rotating with a handle, the rotating part is connected to the tape-shaped cord (1). The connector (1) is attached to the tip derived from (3).
The cord (12) having 1) can be detachably fixed to the clamp (10) provided in the fixed case (2), or the fixed case ( A vehicle air characterized in that a cord (17) having a connector (16) at a tip derived from 2) can be detachably fixed to a clamp (15) provided on a rotating portion (3). It is a temporary fixing structure in the current supply device for a bag, and specifically, the clamp (10)
Is provided on the outer peripheral portion of the fixed case (2), or the clamp (15) is provided on the outer peripheral portion of the upper surface plate (9) forming the rotating portion.

[0005]

FIG. 1 shows an example of a temporary fixing structure according to the present invention.
3 will be described with reference to FIG. FIGS. 1 and 2 show a first embodiment of the present invention, in which (1) is a tape-like cord provided in a spiral shape so as to follow a certain amount of turning operation of a handle. One end of the cord is fixed to the outer peripheral surface of a rotor (7) that rotates together with the handle, and the other end is fixed to the steering column side. The upper part (4) has a hook-shaped section and the lower plate (5) has a flange shape. And is fixed to the inner peripheral wall of a fixing case (2) having a U-shaped cross section.

[0006] (6) is an upper surface plate, which is fixed to the upper portion of the rotor (7) so as to rotate with the rotation of the handle, and both of them form a rotating part (3) and the rotating part (3). )
Is rotatably attached to the inner peripheral portion of the fixed case (2), thereby forming a hollow ring-shaped main body (8). A connector (11) is provided at the top of the upper plate (6), and a steering-side cord (12) connected to one end of the tape-like cord (1) is provided.

The fixed case (2) is provided with a clamp (10) which can be engaged with the cord (12) or a connector (11) at the tip thereof on an outer peripheral portion near an attaching portion of the cord (12) on the steering side. A body-side cord (1) connected to the other end of the tape-shaped cord (1) has a connector (16) at the tip outside the lower surface.
7) is provided.

FIG. 3 shows a second embodiment of the present invention, in which the upper plate (9) is extended to the outer periphery of the fixed case.
It is the same as the first embodiment except that a clamp (15) is provided on the outer peripheral portion of the upper plate (9). The shape of the clamps (10) and (15) is not particularly limited, and may be a hook shape as shown in the drawings, or a double hook shape in which this type of hook is provided in a gate shape. May be.

[0009]

Before the airbag energizing device is mounted on the vehicle, the steering-side cord (12) or the connector (11) is set at the neutral position of the rotating part (3).
Is fixed to the clamp (10) on the fixed case (2) side as shown by a dotted line in FIG. Alternatively, the cord (17) or the connector (16) on the body side is locked to the clamp (15) on the rotating part (3) side as shown by a dotted line in FIG. These are in a temporarily fixed state, and even if stored and transported in this state, the cord and the connector will not come off from the clamp unless a particularly large rotational force is applied to the rotating part or the fixed case.

When the airbag power supply device is mounted on a vehicle, a cord (12) temporarily fixed to a clamp (10) is provided.
Alternatively, the cord (17) or the connector (16) temporarily fixed to the connector (11) or the clamp (15)
Is removed from the clamp (10) or the clamp (15), and fixed at a predetermined position on the vehicle.

[0011]

[Effect of the Invention] As described above, the present invention is used as a means for temporarily fixing a neutral position in a current supply device for an airbag of various vehicles.
Since the fixed case or the rotating part is provided with a clamp and the cord provided in the airbag energizing device or the connector at the tip of the clamp is locked to the clamp, the temporary fixing of the neutral position is performed. Additional processing for temporary fixing is only addition of a clamp, which is simple in structure, economical and practical.
