Abstract
Abstract The inner end surface of the outer end portion of an electrical connector coupling ring has a set of teeth extending circumferentially about the coupling ring. A metal ring has a bore sufficient to enable it being received onto the connector plug and an outer diameter sufficient to enable receipt within the coupling ring and allow the coupling ring to rotate thereabout. One or more keyways on the decoupling ring are interlocked with keys on the connector plug maintaining the antidecoupling ring and plug in fixed relationship to one another, irrespective of movement of the coupling ring. At least one elongated leaf spring has an end formed into a detent that rides along and between the coupling ring teeth. The other spring end is rotatably located on a pivot pin mounted to the circumferential periphery of the anti-decoupling ring.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
275 words
Apparatus deterring relative rotation of a cylindrical coupling shell of an electrical connector with respect to a cylindrical connector part, said coupling shell being telescopingly and rotatably received about said connector part, comprising: circumferentially extending set of teeth formed on a rear end portion of the coupling shell; an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof. an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end portion of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof.
Claim 2
Dependent Claim
275 words
Apparatus deterring relative rotation of a cylindrical coupling shell of an electrical connector with respect to a cylindrical connector part, said coupling shell being telescopingly and rotatably received about said connector part, comprising: circumferentially extending set of teeth formed on a rear end portion of the coupling shell; an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof. an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end portion of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof.
Claim 3
Dependent Claim
22 words
Apparatus as in claim 1, in which key and keyway means interconnect the annular base and connector part preventing relative rotation therebetween.
Claim 4
Dependent Claim
35 words
Apparatus as in claim 1, in which the free end portion of said spring is formed into a cylindrical detent of dimensions suitable to enable said detent to rest within a space between adjacent teeth.
Claim 5
Dependent Claim
40 words
Apparatus as in claim 1, in which first and second detent springs are affixed to the annular base at separate points angularly spaced from one another at approximately 180 degrees and extending about the annular base in the same direction.
Claim 6
Dependent Claim
208 words
Apparatus deterring relative rotation of a cylindrical coupling shell of an electrical connector with respect to a cylindrical connector part, said coupling shell being telescopingly and rotatably received about said connector part, comprising: circumferentially extending set of teeth formed on a rear end portion of the coupling shell, said teeth each being canted in the same direction so that the formed free end portion of the detent spring encounters steeper teeth sides when the coupling shell is rotated in one direction about the connector shell than when it is rotated in the opposite direction; an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end portion of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof.
Claim 7
Dependent Claim
208 words
Apparatus deterring relative rotation of a cylindrical coupling shell of an electrical connector with respect to a cylindrical connector part, said coupling shell being telescopingly and rotatably received about said connector part, comprising: circumferentially extending set of teeth formed on a rear end portion of the coupling shell, said teeth each being canted in the same direction so that the formed free end portion of the detent spring encounters steeper teeth sides when the coupling shell is rotated in one direction about the connector shell than when it is rotated in the opposite direction; an annular base fixedly received on the connector part located spaced from and directly opposite the set of teeth, said annular base having a peripheral surface including first and second radially extending side walls forming an outwardly opening circumferential passage; and an elongated detent leaf spring having one free end portion and one end affixed to the outer circular peripheral surface of the annular base by a pivot pin secured to the base side walls, the spring lying generally along the annular base periphery with the free end portion of the spring riding on the set of teeth and exerting reaction spring pressure between the coupling shell and connector part retarding relative rotation thereof.
Claim 8
Dependent Claim
39 words
Apparatus as in claim 5, in which first and second detent springs are affixed to the annular base at separate points angularly spaced from one another approximately 180 degrees and facing in the same direction about the annular base.
Claim 9
Dependent Claim
22 words
Apparatus as in claim 5, in which key and keyway means interconnect the annular base and connector part preventing relative rotation therebetween.
