Abstract
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.
