Connector having coupling mechanism

A connector comprising:

• a shell having a chamber, the shell having a mating end configured to be mated with a mating connector, the shell holding at least one contact;
• and
• a coupling mechanism rotatable about the shell, the coupling mechanism comprising an inner coupling nut and an outer coupling nut separate from the inner coupling nut, the inner coupling nut having threads configured to be threadably coupled to a mating connector, the inner coupling nut having a track defined by track walls formed into an outer surface of the inner coupling nut, the track comprising a circumferential groove, a tightening slot extending from the circumferential groove and an untightening slot extending from the circumferential groove, the outer coupling nut having a cavity receiving the inner coupling nut, the outer coupling nut having a post extending into the cavity, the post being received in the track, the post being received in the circumferential groove to allow the outer coupling nut to rotate freely relative to the inner coupling nut, the post being received in the untightening slot during rotation of the outer coupling nut in an untightening direction to force the inner coupling nut to rotate in the untightening direction, the post being received in the tightening slot during rotation of the outer coupling nut in a tightening direction to force the inner coupling nut to rotate in the tightening direction.
