The present invention relates to a plastic housing of a conductive steering shaft, and more particularly to a design of a housing of a vehicle steering shaft having an improvement in configuring the plastic housing of the steering shaft.

The conventional steering shaft assembly of a motor vehicle is fastened to the steering shaft jacket 3 by the steering shaft housing 1 to the jacket flange 4 as a special bolt 5, as shown in FIG. 5 as an exploded perspective view. The ignition housing 2 is fastened and assembled to the side and the bottom thereof, respectively, and the rigid shaft housing 1 and the ignition housing 2 are made of different materials, for example, the steering shaft housing 1. The silver housing and the ignition housing 2 were made of zinc casting and used as different rigid materials.

In light of the above problems, the present inventors refer to a product in which the above configuration is unified.

However, in the above design, lack of conductivity between the shafts, and thus can not perform the wiring role in the entire electrical system, so separate wiring is required to use a device such as a Clarkson, generally in the mechanical configuration of a vehicle having a rotating part The problem was found to be very difficult.

Conventional steering shaft housing assembly is a plastic assembly of the conductive steering shaft of the present invention in order to solve such non-conductive problems, as well as the problem of lowering the fuel economy by using a metal material that is difficult to assemble a lot, high labor cost and high specific gravity The housing aims to provide an assembly of a steering shaft housing having an improved configuration and shape.

The plastic housing of the conductive steering shaft of the present invention together with the accompanying drawings will be described in more detail.

1 is an exploded perspective view showing the plastic housing of the conductive steering shaft of the present invention. Figure 2 is a perspective view of the front and rear showing the housing of the steering shaft of the present invention. 3 is a partial cross-sectional view of the plastic housing of the conductive steering shaft of the present invention. 4 is a perspective view of an embodiment of a conductive insert inserted into a plastic housing of a conductive steering shaft of the present invention.

Molding the housing 10 as a material containing an appropriate amount of glass fiber in the polyamide 66, a thermoplastic material, the ignition housing 11 and the steering shaft housing integrally molded and the jacket (3) of the housing 10 If the hollow insert 12 which can be inserted into the tube is extended and constituted, and the projection line 13 along the circumference of the hostile shape is formed on the outer circumferential surface of the hollow insert 12, this projection line at the time of forced insertion As (13) is broken, it can serve as a fixture of the press fit.

In the housing 10, an electrically conductive insert 15 is inserted into one side wall surface of the inner hole 14 in the axial direction, and the electrically conductive insert 15 is connected to the jacket 3 on one side thereof. ) And the other end has an inner surface connecting piece 15 which is an extended metal piece. ) Shape.

Of course, the conductive insert 15 is constituted of a metal material having good conductivity.

The conductive insert 15 may be separately inserted and assembled, but it may be seen from the connection surface that the injection molding of the housing 10 together as possible is possible.

The plastic housing of the conductive steering shaft of the present invention as described above provides a steering shaft housing that completely eliminates the drawbacks of the prior art as a single molding process without additional wiring because the steering shaft housing and the ignition housing are integrally formed and impart conductivity. It is a useful design.
