Abstract: An electrical connector, bridge connector and opening accessory to protect the contacts on flexible circuitry of such connectors from being damaged by the sharp edges of a printed circuit board like member wherein the opening accessory is provided with spaced apart cam means that spread apart cam bearing portions of the connectors outside flexible circuitry mounted thereon is disclosed.

Abstract: A high density and multiple insertion connector that minimizes the amount of friction created by coupling and uncoupling of the connector wherein a generally hourglass-shaped insertion member isolates sliding contact between the components to surfaces of low frictional resistance material during the majority of the insertion and removal movements while providing wiping and high contact forces between electrical contacts.

Abstract: A high-performance, multi-row contact matrix electrical connector having a spring element in the form of an elongated hollow split tube with a mechanical actuator operatively connected to the tube and including first and second sets of parallel spaced conductors terminating at least at one end thereof in a first and second matrix of contact pads, the matrices and the pads being positioned within the split, movement of the mechanical actuator overcoming the spring element to open and close the connector.

Abstract: A high-performance, multi-row contact matrix electrical connector having a spring element in the form of an elongated hollow split tube with a heat-recoverable member of shape-memory alloy positioned within the tube and including first and second sets of parallel spaced conductors terminating at least at one end thereof in a first and second matrix of contact pads, the matrices and the pads being positioned within the split, a change in temperature changing the shape-memory alloy from one metallurgical state to another, causing movement of the heat-recoverable member and the spring means to open and close the connector.
