Abstract
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. The leaf spring is elongated and arcuately shaped, and the axially extending detent portion is disposed on the one leaf portion which forms the concave side of the arcuate shape. The free end of the leaf spring rides along the inner circumferential portion of the coupling ring as the leaf spring is radially deflected by engagement of the detent protrusion thereof with the ratchet teeth of the connector plug.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
154 words
An electrical connector comprising first and second connector members, each connector member including interengageable contact means adapted for axial connection in electrical engagement with the contact means of the other connector; a coupling ring carried by one of said connector members for rotation relative thereto; complementary interengaging connection means between said coupling ring and the other of said connector members; and detent means between said coupling ring and said one connector member, said detent means including a radially deflectable leaf spring on one of said coupling ring or said one connector member, said leaf spring including at least a pair of superimposed leaf portions, a detent protrusion on one of said leaf portions between the ends thereof, and the other of said leaf portions providing a backup means against said one leaf portion to distribute flexing stresses along the length thereof and to limit bending or flexing in the area of said detent protrusion.
Claim 2
Dependent Claim
154 words
An electrical connector comprising first and second connector members, each connector member including interengageable contact means adapted for axial connection in electrical engagement with the contact means of the other connector; a coupling ring carried by one of said connector members for rotation relative thereto; complementary interengaging connection means between said coupling ring and the other of said connector members; and detent means between said coupling ring and said one connector member, said detent means including a radially deflectable leaf spring on one of said coupling ring or said one connector member, said leaf spring including at least a pair of superimposed leaf portions, a detent protrusion on one of said leaf portions between the ends thereof, and the other of said leaf portions providing a backup means against said one leaf portion to distribute flexing stresses along the length thereof and to limit bending or flexing in the area of said detent protrusion.
