Abstract: An electrical connector housing fixable within an opening of a wall comprising an inner housing and an outer housing, the inner housing having a terminal receiving passageway therein, characterized in that in response to relative movement between the housings resilient members which have passed through the opening are expanded outward preventing the housing from backing out of the wall, thereby providing a through-wall housing that is easily inserted and affixed to a wall from one side thereof.

Abstract: A panel mount connector comprises a panel mount component and a movable component. The panel mount connector can be mounted to a panel by a combined sealing and provisional mounting ring. The movable connector part comprises a terminal receiving housing and a bayonet type rotatable locking ring having a first axial position allowing mounting of a rubber boot to the housing, the locking ring retractable to a second position partially extending over the rubber boot in order to prevent it from being accidentally pulled off the housing. The connectors can then be mated together by aligning keying means of the housing with corresponding keying means of the panel connector housing, axially moving the housings together, and then rotating the bayonet type locking ring until an end position whereby the sealing ring is compressed between a flange of the locking ring and the panel for sealing therebetween.

Abstract: An electrical connector assembly is comprised of a housing member having a slidable cover, together which is interconnectable to a header member. The header includes camming grooves positioned on inside surfaces of upstanding walls whereas the connector assembly includes locking lugs positioned on outside surfaces of the cover member. The cover member is transversely slidable relative to the housing such that moving the cover transversely can bring the connector assembly into full electrical engagement with the header assembly.
