Abstract

Each one of multiple spring contacts in printed circuit sheets, and the like, should have individual freedom of motion for each contact land. Such spring contact should be characterized by a minimum degree of creep for a large number of makes and breaks.

Spring Pad for Etched Circuit Electrical Connector

Each one of multiple spring contacts in printed circuit sheets, and the like, should have individual freedom of motion for each contact land. Such spring contact should be characterized by a minimum degree of creep for a large number of makes and breaks.

A creep-free metallic spring pad that provides the required individual freedom of motion of each contact and also a high degree of mechanical accuracy is shown. Contact land 4 is urged into engagement with mating land 6 by spring pad 1. The latter is formed of spun metallic filaments which are retained in cavity 5 by confining membrane 2. Land 4 is provided with substrate 3 that has negligible stiffness.
