Abstract
Abstract An electrical connector is formed from a lamina of elastomeric material having conductive tracks on one surface by folding the lamina and bonding opposed lamina portions together. The conductive tracks extend around the fold between contact portions on opposite surfaces of the connector. Suitably the lamina is of thermoplastic material so that bonding is by fusion and the conductive tracks may be flush with the connector surfaces. The connector is formed in a U-shaped nest under pressure and the lamina is formed about a core of elastomeric material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A method of forming a connector for use between printed circuit boards or the like and having spaced contact portions at opposed surfaces of an elastomeric body, the contact portions on the opposed surfaces being interconnected by conductive paths, the method comprising the steps of; a. forming conductive paths on one surface on a lamina of elastomeric material; b. folding the lamina in generally U-shaped fashion to bring the other surface of the lamina into abutting engagement and with the conductive paths extending along the distal surfaces and around the fold, the portion of the paths between the fold and ends of the lamina providing flat portions adapted to be contacted by the printed circuit boards or the like; and c. bonding the abutting surfaces together.
Claim 2
Independent Claim
126 words
A method of forming a connector for use between printed circuit boards or the like and having spaced contact portions at opposed surfaces of an elastomeric body, the contact portions on the opposed surfaces being interconnected by conductive paths, the method comprising the steps of; a. forming conductive paths on one surface on a lamina of elastomeric material; b. folding the lamina in generally U-shaped fashion to bring the other surface of the lamina into abutting engagement and with the conductive paths extending along the distal surfaces and around the fold, the portion of the paths between the fold and ends of the lamina providing flat portions adapted to be contacted by the printed circuit boards or the like; and c. bonding the abutting surfaces together.
Claim 3
Independent Claim
99 words
A method of forming a connector comprising the steps of: a. providing a flexible strip of thermoplastic elastomeric material with a plurality of conductive circuits printed thereon; b. placing the flexible strip in U-shaped nest with the printed circuits facing the nest surface; c. urging a body of elastomeric material into the nest against the flexible strip; d. forming the connector by heating the strip and body under the urging pressure until fusion of the strip and body occurs; e. cooling the connector to a set condition while still under pressure; and f. removing the connector from the nest.
Claim 4
Independent Claim
99 words
A method of forming a connector comprising the steps of: a. providing a flexible strip of thermoplastic elastomeric material with a plurality of conductive circuits printed thereon; b. placing the flexible strip in U-shaped nest with the printed circuits facing the nest surface; c. urging a body of elastomeric material into the nest against the flexible strip; d. forming the connector by heating the strip and body under the urging pressure until fusion of the strip and body occurs; e. cooling the connector to a set condition while still under pressure; and f. removing the connector from the nest.
Claim 5
Dependent Claim
46 words
A method as claimed in claim 2 characterised in that the body of elastomeric material is urged into the mould nest by a ram of less width than that of the U-shaped nest of the ram being slidable in a guide overlapping sides of the nest.
