ABSTRACT:
The proposed pile-up assembly comprises metallic fastenings with contact springs being placed therebetween. These springs are insulated from one another by plates made of a thermoplastic material. The assembly also comprises a bush extending through openings made in the fastenings and the plates and connecting all the assembly components. Each plate is provided, according to the invention, with projections running the length of the surface facing the contact springs. The height of the projections is chosen so that when the invention is clamped during assembly, the contact springs are depressed against said projection until they come in contact with the surface of the plates. Employment of the proposed invention permits a reduction of labor consumption during assembly.
