  • Patent number: 5425171
    Abstract: An insert retention gas tight seal for an electrical connector is disclosed. The insert retention, gas tight seal includes an annular groove defined by the interior surface of the connector housing within the receptacle and the plug, an annular ring of soft metal, and a tool to force the ring into the annular groove into a sealing, locked position within the connector housing of the receptacle and the plug. A method of fabrication for the insert retention, gas tight seal for an electrical connector is also described.

  • Patent number: 5141448
    Abstract: An apparatus for retaining a coupling ring such as a canted washer or spring for use in non-self locking electrical connectors is disclosed. The canted washer or spring having uniform frustoconical surface is positioned between the plug and coupling ring providing a known spring force response between the coupling ring and plug shell shoulder. In one embodiment, the canted washer is used in a non-bayonet electrical connector with a swaged coupling ring. An alternative embodiment is described as a double turn canted spring used in conjunction with a non-swaged, grooved coupling ring. The apparatus is used in both metal and composite non-bayonet electrical connectors. Configuration to a particular cant for either the canted washer or spring is calculable using known factors such as; size, material thickness, and the modulus of the material. A canted washer or wave spring for use in electrical connectors subjected to high and low temperature environments is also disclosed.
