Abstract: An electrical connector is disclosed and has complementary receptacle and plug connector members, each member having a hollow shell containing a conventional insulating insert which houses electrical contacts. A rotatable coupling ring is carried by the plug and is engageable with the receptacle for mating the connector members and holding the contacts in electrical engagement. A radially deflectable detent leaf spring is carried on an inner circumferential portion of the coupling ring, and the leaf spring has a radially extending detent protrusion intermediate the ends thereof and engageable with an annular array of ratchet-type detent teeth on an outer circumferential portion of the connector plug. The leaf spring is comprised of a pair of superimposed leaf portions joined together integrally at adjacent ends thereof by an enlarged loop portion. The loop portion is positionable within an axially exposed mounting recess at one end of the coupling ring.

Abstract: An electrical connector is disclosed comprising complementary receptacle and plug connector members, each member having a hollow shell containing an insulating insert which houses electrical contacts. A rotatable coupling ring is carried by the plug and is engageable with the receptacle for mating the connector members and holding the contacts in electrical engagement. A resilient means is interposed between the coupling ring and the plug and has a predetermined range of axial deflection relative to the plug. The receptacle is provided with a plurality of bayonet pins and the coupling ring has a corresponding plurality of pin-receiving tracks to provide a bayonet type releasable connection between the coupling ring and the receptacle. The coupling ring has limited axial movement relative to the plug so that upon mating of the connector members, the coupling ring moves axially along the plug toward the receptacle compressing the resilient means therebetween.
