Abstract
Disclosed is an electrical connector having a substrate and movable electrical contacts which are mounted to the substrate and extend a distance D from the substrate. A layer of compressible material (such as a foam or elastomeric material) is positioned on the substrate adjacent at least some of the electrical contacts and ideally has an uncompressed thickness slightly greater than the distance D to provide for protection of the electrical contacts. When a mating electrical device such as an electrical connector or other circuit member is mated to the electrical connector with its electrical contacts and its layer of compressible material, the layer of compressible material is compressed to a thickness less than the distance D, allowing the contacts to make a suitable electrical interconnection to the mating electrical device. The compressible material may be selected which has a force-to-compression plot which includes at least one inflection, defining a first region on one side of the inflection where a given increment of force provides a larger increment of compression and a second region on the other side of the inflection where the same increment of compressive force provides…
