Abstract
Abstract The invention concerns connectors having an elongate spring body of elastomer or formed as a tubular spring about which a single layer wire coil is wound. The coil turns are separated by cutting the coil longitudinally of the body to define discrete conductive paths of C-shape extending round part of the circumferential profile of the body. Exposed surface portions of the wires present contact points in a row along the body. Each C-shaped turn may present a pair of diametrically opposite contacts. The coil may be wound about a former disposed beside the spring body so that on cutting the turn portions at the former leads to the individual C-shaped turn portions extend freely from the spring body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
An electrical connector comprising an elongate spring body having a generally uniform cross-section, which is resiliently deformable transversely of its length and which has discrete conductive paths disposed in insulating spaced relationship around the body, said conductive paths comprising a conductor wire coil wound around said spring body and being disposed in closely uniformly spaced turns along said body, said conductor wire being bonded to said body and having a portion removed from each said turn thereby forming said discrete conductive paths, each path being of generally C-shaped turn form extending around part only of the circumferential periphery of the spring body, each path further comprising a lead portion extending freely away from said spring body, said lead portion being an integral part of the coil wound conductor wire, and exposed surface portions of the wire on each said turn defining at least a row of contact points distal from and extending along the spring body.
Claim 2
Dependent Claim
156 words
An electrical connector comprising an elongate spring body having a generally uniform cross-section, which is resiliently deformable transversely of its length and which has discrete conductive paths disposed in insulating spaced relationship around the body, said conductive paths comprising a conductor wire coil wound around said spring body and being disposed in closely uniformly spaced turns along said body, said conductor wire being bonded to said body and having a portion removed from each said turn thereby forming said discrete conductive paths, each path being of generally C-shaped turn form extending around part only of the circumferential periphery of the spring body, each path further comprising a lead portion extending freely away from said spring body, said lead portion being an integral part of the coil wound conductor wire, and exposed surface portions of the wire on each said turn defining at least a row of contact points distal from and extending along the spring body.
Claim 3
Dependent Claim
38 words
A connector as claimed in claim 1, in which the C-shaped turns extend around more than half of the circumferential periphery of the body and present diametrically opposite rows of contact points extending longitudinally of the spring body.
Claim 4
Dependent Claim
18 words
A connector as claimed in claim 2, in which the spring body is formed of elastomeric insulating material.
Claim 5
Dependent Claim
19 words
A connector as claimed in claim 2, in which the spring body is a tubular form of C-shaped cross-section.
Claim 6
Dependent Claim
27 words
A connector as claimed in claim 4 in which the tubular spring body is of metal and the wire turns are electrically insulated from the spring body.
Claim 7
Dependent Claim
46 words
A connector as claimed in claim 5 in which the wire turns are of insulated wire from which the insulation is removed at exposed surface portions distal from the spring body to define at least one row of contact points extending longitudinally of the spring body.
Claim 8
Dependent Claim
26 words
A connector as claimed in claim 2 in which the contact points are defined by spot depositions of metal plating on the exposed wire surface portions.
