Abstract

Abstract An electrical connector adapted to be secured to a mating electrical connector. A first member extends outwardly from the connector shell with indentations formed on a radially extending surface of the first member. A coupling nut is axially aligned with the connector and surrounds a portion of the connector outer shell. A pair of longitudinally extending slots are formed on the outer surface of the coupling nut. A second member is longitudinally movable in the slot and rotatable with the coupling nut. Protrusions on the second member surface interact with the first member indentations for varying the tightness between the electrical connector and the mating electrical connector. A spring member is positioned adjacent the second member for urging the second member protrusions to interact with the first member indentations. Indicator means are provided on the outer surface of the coupling nut. The second member extends to the outer surface of the coupling nut, and alignment of the second member with the indicator means provides a visual and tactile indication of the desired degree of tightness between the mated connectors.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 188 words
An electrical connector having an outer shell and adapted to be secured to a mating electrical connector comprising: a first means extending outwardly from said shell and having spherical discontinuities unitarily formed on a radially extending surface; a coupling nut axially aligned with said connector member and surrounding a portion of said connector outer shell; a longitudinally extending slot formed on the outer surface of said coupling nut; and a second means longitudinally movable in said slot and having discontinuities unitarily formed on the surface thereof and interacting with said first means discontinuities to vary the degree of tightness between said connector member and a mating connector member when said connector members are secured together; and said discontinuities on one of said means extending along the axis of said connector shell to form depressions on a relatively smooth surface formed in a plane perpendicular to said connector shell axis, and said discontinuities on said other of said means extending along said axis of said connector shell to form a plurality of protrusions extending from a relatively smooth surface formed in a plane perpendicular to said connector shell axis.
Claim 2
Dependent Claim 188 words
An electrical connector having an outer shell and adapted to be secured to a mating electrical connector comprising: a first means extending outwardly from said shell and having spherical discontinuities unitarily formed on a radially extending surface; a coupling nut axially aligned with said connector member and surrounding a portion of said connector outer shell; a longitudinally extending slot formed on the outer surface of said coupling nut; and a second means longitudinally movable in said slot and having discontinuities unitarily formed on the surface thereof and interacting with said first means discontinuities to vary the degree of tightness between said connector member and a mating connector member when said connector members are secured together; and said discontinuities on one of said means extending along the axis of said connector shell to form depressions on a relatively smooth surface formed in a plane perpendicular to said connector shell axis, and said discontinuities on said other of said means extending along said axis of said connector shell to form a plurality of protrusions extending from a relatively smooth surface formed in a plane perpendicular to said connector shell axis.
Claim 3
Dependent Claim 23 words
An electrical connector in accordance with claim 1 wherein said second means comprises a clutch plate which is rotatable with said coupling nut.
Claim 4
Dependent Claim 44 words
An electrical connector in accordance with claim 2 wherein said first means comprises a flange integrally formed with said connector shell and wherein a spring member is positioned adjacent said clutch plate for urging said clutch plate discontinuities to interact with said flange discontinuities.
Claim 5
Dependent Claim 47 words
An electrical connector in accordance with claim 3 wherein said flange discontinuities are formed of indentations formed on said flange surface and said clutch discontinuities are formed of protRusions formed on a surface of said clutch plate which is in a plane parallel to the flange surface.
