Abstract
Abstract Connector device including a leaf detent spring disposed between facing annular surfaces of a pair of rings and engageable in a key slot in one of the rings to lock the rings against relative rotation. Preferably, one of the rings is a coupling ring threaded on a shell of an electrical connector to move an insert member into the shell and to lock contact means within an insulating body in the shell, the detent spring being releasable to allow reverse rotation of the coupling ring and release of the lock of the contact means, so that the contact means may be removed for servicing or replacement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
257 words
In an electrical connector device, first and second generally cylindrical members in coaxial relation to each other, insulating body means within said first cylindrical member, electrical contact means within said insulating body, a coupling ring threaded on said first cylindrical member, said second cylindrical member and said coupling ring having interengaging surfaces to move said second cylindrical member toward said first cylindrical member with rotation of said coupling ring in one direction, said electrical contact means being locked in said insulating body when said coupling ring is rotated in said one direction to a certain position relative to said first cylindrical member and being removable from said insulating body upon rotation of said coupling ring to a certain extent in the reverse direction, a lock ring fixedly disposed on said second cylindrical member, and detent spring means acting between said coupling and lockrings for releasably locking said coupling ring in said certain position, said coupling and lockrings having annular surfaces in planes transverse to the axis thereof and in facing relation, one of said rings being formed with a key slot in the annular surface thereof, said detent spring means comprising a leaf spring member between said annular surfaces having an outer end portion biased axially to lockingly engage in said key slot in said certain position, and securing means securing an inner end portion of said leaf spring member against rotation relative to the other ring, said outer end portion being manually movable axially out of said key slot to allow relative rotation of said rings.
Claim 2
Dependent Claim
257 words
In an electrical connector device, first and second generally cylindrical members in coaxial relation to each other, insulating body means within said first cylindrical member, electrical contact means within said insulating body, a coupling ring threaded on said first cylindrical member, said second cylindrical member and said coupling ring having interengaging surfaces to move said second cylindrical member toward said first cylindrical member with rotation of said coupling ring in one direction, said electrical contact means being locked in said insulating body when said coupling ring is rotated in said one direction to a certain position relative to said first cylindrical member and being removable from said insulating body upon rotation of said coupling ring to a certain extent in the reverse direction, a lock ring fixedly disposed on said second cylindrical member, and detent spring means acting between said coupling and lockrings for releasably locking said coupling ring in said certain position, said coupling and lockrings having annular surfaces in planes transverse to the axis thereof and in facing relation, one of said rings being formed with a key slot in the annular surface thereof, said detent spring means comprising a leaf spring member between said annular surfaces having an outer end portion biased axially to lockingly engage in said key slot in said certain position, and securing means securing an inner end portion of said leaf spring member against rotation relative to the other ring, said outer end portion being manually movable axially out of said key slot to allow relative rotation of said rings.
Claim 3
Dependent Claim
35 words
In an electrical connector device as defined in claim 1, said outer end portion of said spring member having a terminal end projecting radially outwardly beyond the outer periphery of said one of said rings.
Claim 4
Dependent Claim
16 words
In an electrical connecTor device as defined in claim 2, said terminal end being curled inwardly.
Claim 5
Dependent Claim
79 words
In an electrical connector device as defined in claim 2, said other of said rings having a key slot in said annular surface thereof aligned with said key slot of said one of said rings in said certain position, said outer end portion of said spring member being manually movable out of said key slot of said one of said rings and into said key slot of said other of said rings to allow relative rotation of said rings.
Claim 6
Dependent Claim
34 words
In an electrical connector device as defined in claim 1, a flat ring disposed between inner portions of said annular surfaces, said inner portion of said spring member being integral with said flat ring.
Claim 7
Dependent Claim
52 words
In an electrical connector device as defined in claim 5, said securing means comprising a second leaf spring member integral with said flat ring and projecting radially outwardly therefrom in angularly spaced relation to the first-mentioned spring member, said other of said rings having a slot therein receiving said second spring member.
