Abstract
Abstract The invention concerns a method of making a connector body comprising a multiplicity of spaced resilient conductive springs disposed within a matrix of elastomeric insulating material defining a body having spaced surface parts between which the springs extend in non-rectilinear paths and at which ends of the springs are exposed. According to the method at least one wire is wound into a coil of spaced turns and the coil is potted in a mass of elastomer. The resulting body is cut through the coil turns to present the spaced surface parts. To facilitate coil formation and potting, the wire may be wound with elastomer strip or sheet spacing and the composite coil then cured to form a bond between contiguous elastomer surfaces and define a coherent matrix. Alternatively the elastomer may be injection or vacuum molded in the fluent state.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
A method of manufacturing a connector body comprising a multiplicity of spaced resilient conductive springs disposed within a matrix of elastomeric insulating material defining a body having spaced surface parts between which the springs extend in non-rectilinear paths and at which ends of the springs are exposed, said method comprising the steps of winding a plurality of wires into individual coils of flat turns at spaced intervals axially of a cylindrical former, interleaving a sheet of elastomeric material in a manner so as to be common to the plurality of wires, said elastomeric material being wound in a coil disposed between each turn of the individual coils of said wires, bonding adjacent layers of the elastomeric sheet material through the interwire spaces to form a coherent matrix, and cutting through the coil turns to define the connector body with cut portions presenting the spaced surface parts.
Claim 2
Independent Claim
146 words

Claim 3
Dependent Claim
69 words
A method as claimed in claim 1, in which two sets of several wires each associated with a respective sheet of elastomeric insulating material are wound into a composite coil as alternating layers, the wires of one set being staggered longitudinally of the coil in relation to those of the other set so that a wire in any layer lies between adjacent wires in the adjacent layer or layers.
Claim 4
Dependent Claim
33 words
A method as claimed in cLaim 1, in which uncured or partly cured elastomer is wound into the coil and curing is then completed to effect bonding between adjacent layers of the elastomer.
Claim 5
Dependent Claim
36 words
A method as claimed in claim 1, in which elastomer strip or sheet having an adhesive or solvent surface coating is wound into the coil and subsequently set or cured or evaporated to bond adjacent layers.
Claim 6
Dependent Claim
25 words
A method as claimed in claim 1, in which a vulcanizable elastomer is wound into the coil and is subsequently vulcanized to bond adjacent layers.
