[Structure] A cord with a connector provided on a rotating side of a current carrying device for an airbag of a vehicle is locked to a clamp provided on a fixed case side, or a cord with a connector provided on the fixed case side is rotated. Temporary fixing is performed by engaging with the clamp provided on the side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temporary fixing structure for a current carrying device used for transmitting and receiving an electric signal between a steering wheel having a limited number of rotations and a steering column, such as a steering device for a vehicle equipped with an airbag. It is a thing.

[0002]

[Prior art]

 Conventionally, there are various types of electrical connection devices between a steering wheel equipped with an airbag and a steering column, but all of them require a temporary fixing means to maintain a neutral position between the steering wheel and the steering column. As a simple structure of this temporary fixing means, for example, there is one described in Japanese Utility Model Laid-Open No. 2-41389, which is provided with a tongue on the stator side (fixed side) and also on the rotor side ( The rotation side) requires an engagement hole or an engagement projection into which the tongue is fitted.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional product, it is necessary to provide or process an additive on both the stator side and the rotor side, and since the tongue-shaped body is formed of resin integrally with the stator, when temporarily fixing it, It wasn't so realistic as it might break.

[0004]

[Means for Solving the Problems]

 The present invention is a further simplification of the conventional product, and uses a cord with a connector on the fixed case side or the rotating side, which is provided in a vehicle airbag current-carrying device, and uses this cord on the cord mounting side. The above problem was solved by temporarily fixing it to the clamp provided on the opposite side. That is, according to the present invention, a tape-shaped cord (1) formed in a spiral shape so as to follow the turning operation of the steering wheel is attached to the steering column side, and a non-rotating fixed case (2) and a steering wheel (2) are provided. A vehicle air bag energization device housed in a main body (8) that is attached to the side and that rotates with a handle (3), connected to the tape-shaped cord (1), The cord (12) having the connector (11) at the tip drawn out from the moving part (3) can be detachably fixed to the clamp (10) provided in the fixed case (2), or A cord (17), which is connected to the tape-shaped cord (1) and has a connector (16) at the tip led out from the fixed case (2), is attached to a clamp (15) provided on the rotating portion (3). Removably fixed It is a temporary fixing structure in a vehicle air bag current-carrying device, characterized in that the clamp (10) is provided on the outer peripheral portion of the fixed case (2). Alternatively, the clamp (15) is provided on the outer peripheral portion of the upper plate (9) forming the rotating portion.

【Example】

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

(6) is a top plate, which is fixed to the upper part of the rotor (7) so as to rotate with the rotation of the handle, and these both form a rotating part (3) and the rotating part ( The hollow ring-shaped main body (8) is formed by rotatably mounting the inner peripheral portion of the fixed case (2). The top plate (6) is provided with a connector (11) at its tip, and a steering-side cord (12) connected to one end of the tape-shaped cord (1).

The fixed case (2) is provided with a clamp (10) capable of engaging the cord (12) or a connector (11) at its tip with an outer peripheral portion near the steering-side cord (12) mounting portion. On the outer side of the lower surface, a body side cord (17) having a connector (16) at the tip and connected to the other end of the tape-shaped cord (1) is provided.

FIG. 3 shows a second embodiment of the present invention, in which the top plate (9) is extended to the outer peripheral part of the fixed case, and the clamp (15) is the outer peripheral part of the top plate (9). It is the same as the first embodiment except that it is provided in. The shape of the clamps (10) and (15) is not particularly limited, and may be a hook shape as shown in the drawing, or a double hook shape in which hooks of this kind are provided opposite to each other in a gate shape. But it's okay.

[0009]

[Action]

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

When the air bag energization device is attached to the vehicle, the cord (12) or the connector (11) temporarily fixed to the clamp (10) or the cord (17) temporarily fixed to the clamp (15). ) Or the connector (16) is removed from the clamp (10) or the clamp (15), and fixed in place on the vehicle.

[0011]

[Effect of device]

 As described above, the present invention provides a clamp on a fixed case or a rotating portion as a temporary fixing means for a neutral position in an air bag energizing device for various vehicles, and a code provided on the clamp for the air bag energizing device. Alternatively, the connector at the tip is locked to temporarily fix the neutral position, so the only additional processing for temporary fixing is the addition of a clamp, which is economical and practical with a simple structure. It is expensive.
