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: 5
Claim 1
Independent Claim
146 words
A method of manufacturing an electrical connector comprising the steps of providing an elongate spring body having a generally uniform cross-section which is resiliently deformable transversely of the body length, locating a former body beside the spring body whereby the former body extends longitudinally of and projects laterally from the spring body, winding a single layer coil of conductor wire around the spring body and the former body to extend longitudinally in closely spaced turns, bonding the turns to the spring body, cutting the coil longitudinally at turn portions around the former body and spaced from the spring body to separate adjacent turns thereby defining discrete conductive paths disposed in insulating spaced relationship around the spring body and integral lead conductors extending from the turns on the spring body to the cut portion on the former body, and removing the former body from the spring body.
Claim 2
Independent Claim
146 words
A method of manufacturing an electrical connector comprising the steps of providing an elongate spring body having a generally uniform cross-section which is resiliently deformable transversely of the body length, locating a former body beside the spring body whereby the former body extends longitudinally of and projects laterally from the spring body, winding a single layer coil of conductor wire around the spring body and the former body to extend longitudinally in closely spaced turns, bonding the turns to the spring body, cutting the coil longitudinally at turn portions around the former body and spaced from the spring body to separate adjacent turns thereby defining discrete conductive paths disposed in insulating spaced relationship around the spring body and integral lead conductors extending from the turns on the spring body to the cut portion on the former body, and removing the former body from the spring body.
Claim 3
Dependent Claim
59 words
A method as set forth in claim 1 further comprising the step elastically deforming the spring body in the same sense as the lead of the coil prior to winding the coil, and holding the spring body in the elastically deformed condition until after the coil cutting operation when the deformation is relaxed and the coil turns thereby flattened.
Claim 4
Dependent Claim
40 words
A method as set forth in claim 1 further comprising the step of locating a second spring body beside the former body and opposite to the first spring body, and winding the coil around both spring bodies and former body.
Claim 5
Dependent Claim
50 words
A method as set forth in claim 1 further comprising the step of cleaning portions of the coil turns exposed externally of the spring body to expose bare metal portions in a row extending longitudinally of the spring body, and spot plating the bare metal portions to define contact points.
