Patent ID: 7845963

Claim:
An electrical connector that includes a barrel ( 12 ) for holding a contact-mounting body ( 20 ), a coupling nut ( 14 ) extending around said barrel and rotatable on said barrel about an axis ( 26 ), and a mechanism ( 40 ) coupled to said barrel and nut that resists rotation of the nut in at least a first direction of rotation about said axis, said mechanism includes a washer ( 42 ) that is fixed against rotation relative to said nut ( 14 ) and a toothed ring ( 44 ) that is fixed against rotation relative to said barrel ( 12 ), wherein: said nut has a plurality of washer-support surface portions ( 68 ); said washer comprises an initially flat ring that is bent to form a plurality of circumferentially-spaced resting locations ( 60 , 62 , FIG. 2 ) that rest against said washer-support surface portions ( 68 ), and said washer has a plurality of sides ( 64 , 66 ) that each forms a rearward projection ( 70 , 72 ) that each projects rearward (R) from a corresponding one of said sides; said washer being bent so said sides ( 64 , 66 ) lie rearward (R) of said front resting locations ( 60 , 62 ), whereby the washer provides projections that lie against said toothed ring and also provides a spring force that presses the projections of the washer against the toothed ring.
