Abstract
Abstract A matrix connector comprises an elastomer body presenting a pair of opposite contact faces at each of which is disposed a multiplicity of spaced contacts, contacts of opposite faces being interconnected by conductors extending through the body and being defined by convex folds in the conductors. Individual rows of contacts and their conductors are formed on flexible printed circuit laminae of which edge portions are turned to define the folds. A stack of laminae alternating with elastomeric strip material define the connector. Manufacture is suitable by compressing such a stack to extrude the elastomer through apertures in the printed circuits and curing the elastomer into a homogeneous mass.

Claim 1
Independent Claim
206 words
A method of manufacture of a connector comprising the steps of forming a plurality of strip-like flexible lamina printed circuits, each strip-like printed circuit lamina having circuit paths on one side only, the circuit paths comprising conductive strips spaced longitudinally of the strip-like lamina and each extending transversely between opposite side edge portions of the strip, forming the apertures in the insulating lamina, folding over the opposite side edge portions of each strip onto the side of the lamina devoid of circuit paths so that the transverse conductors extend externally of the folds of the side edge portions, disposing between the opposite folds of each strip-like printed circuit and adjacent the side devoid of circuits a first strip of partially cured or thermoplastic elastomeric insulating material, positioning the assemblies of printed circuit laminae and first elastomeric strips in a stack alternating with second strips of elastomeric insulating material, compressing the stack to effect extrusion of the first and second elastomeric strips through the apertures of the printed circuit laminae and into troughs within the folded side edge portions, and curing the elastomer into a homogeneous mass encasing the printed circuit laminae with convex portions of the folded conductors exposed at opposite faces of the elastomeric mass.
