A self-locking electrical connector has (a) a first shell body for receiving a first set of contacts; (b) a clamping ring for holding the first set of contacts in engagement with a second set of contacts; (c) a multiplicity of first detent members; (d) a multiplicity of second detent members; and (e) biasing means for holding the first and second detent members in facing engagement. The biasing means includes at least one spring washer, an end cap and a retaining ring retained within the clamping ring. The at least one spring washer is disposed between the detent members and the end cap. The end cap is axially movable by a force applied by the retaining ring between (i) a non-mated position wherein the at least one spring washer applies less than a desired amount of force to the detent members, and (ii) a mated position wherein the at least one spring washer applies a precise amount of desired force to the detent members.

Self-locking electrical connector

A corrosion-resistant and electrically conductive connector shell includes a shell member formed of an aluminum alloy; an anodic surface coating formed on and extending into the shell member, having an approximate thickness between 0.0008 inch and 0.0018 inch; and a conductive metal plating covering and sealing the anodic surface coating. The metal plating can be a single layer of high purity aluminum having a thickness of 0.0002 inch. Alternatively, the metal plating can include a layer of a first metal on the anodic surface coating and having a thickness of at least approximately 0.00002 inch, and a layer of a second metal such as cadmium having a thickness of approximately 0.0002 inch on the layer of first metal. Also disclosed is a method for forming a corrosion-resistant and electrically conductive connector shell including the steps of providing an aluminum alloy shell member; forming an anodic coating on and extending into the shell member; and plating a single layer of aluminum by ion vapor deposition on the anodic coating.
