Antirotation coupling for connector

摘要

A mechanism (20) for connecting the coupling nut (14) and barrel (12) of an electrical or optical connector to resist but not prevent their relative rotation, includes a clicker ring (22) that has forward-projecting teeth (36) and that fits into a circular recess (32) at the rear of the coupling nut to engage rearward-projecting nut teeth (34). The clicker ring also has slots (40) that receive radially-outward projections (42) on the barrel, to prevent clicker ring turning.

主权项

1. A connector which includes a barrel (12) that has an axis (30) extending in forward and rearward directions, and a coupling nut (14) that lies around and is rotatable around the barrel, wherein:
said coupling nut has a ring of nut teeth (34); and including: a clicker ring (22) that has a plurality of rigid clicker teeth (36) engaged with said nut teeth to resist rotation of the coupling nut; of said barrel and said clicker ring, one has a plurality of radial projections (42) and the other has a plurality of slots (40) that receive said projections and prevent clicker ring rotation despite slight axial movement of the clicker ring as said nut and clicker teeth move across one another, and said barrel (12) projects through a majority of the axial length of said nut (14) to engage said clicker ring (22); a spring (24) that biases said clicker ring forward to keep its clicker teeth engaged with said nut teeth of said coupling nut.
