Abstract
The electrical connector of the present invention includes an electrically conductive sleeve having a passage therethrough and an elastomeric housing molded therearound. After the molding of the housing around the sleeve, contact element is disposed within the passage of the sleeve for engagement with the contact member of another connector. An arc snuffer housing and arc snuffer are attached to one end of the contact element for guiding the contact member toward the contact element and for evolving an arc-quenching gas in response to an arc being struck between the contact member and the contact element. The contact element includes a piston member responsive to the evolved gas for jointly displacing within said passage the arc snuffer and contact element toward the contact member. A support member is provided within the sleeve for reciprocably supporting the piston member of the contact element. The piston member includes a friction surface to inhibit the movement of the piston member within the conductive sleeve until a pre-determined pressure is achieved by the arc-quenching gas and for electrically engaging the piston member with the conductive sleeve for providing electrical continuity therebetween.
