Description

Description: FIELD OF THE INVENTION The present invention relates to a conductive connector for bridging a conductor break between relatively rotatable parts, in particular between a handle and a steering column. Has a conductor drawer and a lid,
A housing as a stator that can be fixed to the steering column,
A rotor rotatably bearing within the housing, also having a conductor drawer, and having a rotor coupled to the handle, the housing and the rotor defining an annular chamber surrounding the rotor, the annular chamber comprising: The present invention relates to a conductive connector operable to receive an insulated strip conductor wound around a rotor a plurality of times and having an end reaching a conductor lead-out portion.

[Conventional technology]

Such conductive connectors are used, in particular, for electrically connecting the power supply of a motor vehicle to an airbag-type catch protection provided in a steering wheel disc. In this case, the insulated strip conductor provided in the housing chamber has such a length as to be able to follow the rotation of the handle which makes approximately three turns in both directions. The strip conductor expands outward when the handle is cut from its central position in one direction until it contacts the stationary housing and contracts inward when cutting in the other direction until it contacts the rotor.

[Problems to be solved by the invention]

This known conductive connector has proven to work well, however, the strip conductors guided in the housing on the one hand generate scratching noise during normal handle operation and on the other hand a sudden strong shock. In such a case, for example, when the vehicle travels on a curve or an uneven road, there is a disadvantage that strong rattling noise is generated.

An object underlying the present invention is to provide a conductive connector that can easily prevent the generation of noise.

[Means for solving the problem]

The object is to provide a conductive connector of the type mentioned at the outset, in which the insulated conductor side of the bottom and lid of the housing is provided with a coating of fiber sound insulation, respectively, and the fiber sound insulation is bonded. The problem is solved by being formed by a polyethylene fiber fleece which has been hardened by an agent into an insulating felt having high wear resistance.

[Action and Effect of the Invention]

According to the present invention, the following conductive connector is provided. In other words, a conductive connector is provided in which the strip conductors are guided between the fiber layers, thereby preventing the windings of the strip conductors from producing an impact sound from hitting one another or, in the unlikely event, in extreme situations. In this case, surprisingly,
Despite the fact that the edges of the strip conductor are closely guided on the coating layer, it has been found that, for a long period of time, there is no need to worry about the wear of the fiber fleece, which was initially a concern, and the functional effects of this wear. Was.

Other embodiments and advantages will be apparent from the description below. In the following description, the present invention will be described by way of example with reference to the accompanying drawings.

〔Example〕

Shown in the figure is a conductive connector for bridging a conductor break (conductor separation) between a steering column fixed to the vehicle body and a handle rotatable on the steering column. This conductive connector includes a housing 1 as a stator which can be fixed to a steering column and has a conductor lead portion 8a and a lid 2, and a rotatable bearing mounted on the housings 1 and 2, and also has a conductor lead portion 8. Rotor 3. Housing 1,
2 and the rotor 3 connected to the handle are formed so as to surround the annular chamber. This annular chamber serves to accommodate the strip conductor 6 which is wound around the rotor a plurality of times and whose end communicates with the conductor lead-outs 8, 8a.

In this case, the conductor lead-out portion can be formed by a contact pin, and the end of the strip conductor is fixed to the contact pin. However, it is also possible for the strip conductor itself to pass through the rotor or housing, for example by extrusion coating, so that the strip conductor itself forms a conductor draw-out.

The bottom of the housing 1 and the lid 2 are each provided with a coating of fibrous (woven) sound insulation 5,5a. This coating can be made of polyethylene fiber fleece or other suitable material. Other suitable materials are those which have been consolidated by a binder into a high wear resistant insulating felt. The felt layer can be secured to the bottom or lid of the housing in any known manner, for example by a self-adhesive coating.

Embodiments of the conductive connector according to the present invention are as follows.

1. The conductive connector according to claim 1, wherein the felt layer is fixed to a bottom or a lid of the housing by a self-adhesive film.
