Abstract
Abstract An electrical male connector assembly incorporates a floating shield that is resiliently held in a position on the connector body wherein the male contact pins are hidden or shielded from contact by the shield in its outermost position. When the connector member is mated with a corresponding female connector, the opposed face of the female connector impinges on the shield and cause it to be slid along the contact pins to a retracted position. Means are provided for biasing the shield toward its outermost position. The shield face is metalized to provide an exposed ground plane in electrically conductive contact with a metal portion of the connector member shell to drain off any electrical static discharges that might otherwise come into contact with the exposed contact pins.
