Abstract
An electrical connector for providing electrical connection to a substrate having contact elements thereon (e.g., a printed circuit board) wherein torsional contacts are utilized. The contacts, actuated by a vertically moving, slidable member (e.g., a cam plate) and horizontally moving actuator (e.g., a linear cam), resume a normal, twisted configuration to effect such connection with the respective contact elements. Each contact, preferably metallic (e.g., beryllium copper), includes a curvilinear edge segment while each contact element (e.g., plated copper wire) in turn includes a curvilinear contacting surface, these two members thus providing a single point form of contact while assuring effective wiping motion to remove undesirable contaminants, debris, etc. which may be located thereon. Relatively high contact forces (e.g., 200,000 PSI) are possible using the invention.
