Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
A relay contact pile-up assembly comprising: metallic fastenings with holes; contact springs placed between said fastenings; plates of thermoplastic material provided with holes and having projections running the length of the surface facing said contact springs, said plates insulating said contact springs from one another; a bush extending through said holes in said fastenings and said plates and connecting all said parts of the assembly; the height of said projections being chosen so that when the assembly is compressed in the process of assembly, said contact springs are depressed against said projections until they come in contact with the surface of said plate.
Claim 2
Dependent Claim
103 words
A relay contact pile-up assembly comprising: metallic fastenings with holes; contact springs placed between said fastenings; plates of thermoplastic material provided with holes and having projections running the length of the surface facing said contact springs, said plates insulating said contact springs from one another; a bush extending through said holes in said fastenings and said plates and connecting all said parts of the assembly; the height of said projections being chosen so that when the assembly is compressed in the process of assembly, said contact springs are depressed against said projections until they come in contact with the surface of said plate.
Claim 3
Dependent Claim
26 words
A relay contact pile-up assembly as claimed in claim 1, wherein the height of said projections is less than half the thickness of said contact springs.
Claim 4
Dependent Claim
109 words
A relay contact pile-up assembly including metallic fastenings with holes, contact springs placed between said fastenings, insulating plates with holes placed between said springs and insulating said springs from one another, and a bush extending through said holes in said fastenings and said plates and connecting all of said parts of said assembly, said assembly further comprising: projections on the surfaces of the plates facing the contact springs, said projections extending the length of said surface, the height of said projections being selected such that when said assembly is depressed during assembly, said contact springs are depressed against said projections until said springs come in contact with said plate.
Claim 5
Dependent Claim
109 words
A relay contact pile-up assembly including metallic fastenings with holes, contact springs placed between said fastenings, insulating plates with holes placed between said springs and insulating said springs from one another, and a bush extending through said holes in said fastenings and said plates and connecting all of said parts of said assembly, said assembly further comprising: projections on the surfaces of the plates facing the contact springs, said projections extending the length of said surface, the height of said projections being selected such that when said assembly is depressed during assembly, said contact springs are depressed against said projections until said springs come in contact with said plate.
