Abstract
An electrical connector (10) adapted for connection to a complementary connector includes an insert (16) having a plurality of connecting elements disposed within a cylindrical molded body (14) from which a multi-conductor cord (12) extends. A coupling nut (22) is disposed about the insert (16) and has inner threads (22a) for engaging and drawing the complementary connector into secure engagement with a first surface (26a) of an annular flange (26) disposed about the periphery of the insert. In one embodiment, the coupling nut (22) includes an annular, inner flange (34) having a plurality of spaced, symmetrical detents (36) forming teeth. A washer (24) includes asymmetrical projections or teeth on one surface which engage the annular flange of the insert when coupling nut (22) is tightened. The washer (24) further includes second symmetrical projections (50) on a second, opposed surface to form a driving engagement with corresponding teeth on the coupling nut. An outer sheath (60) may be assembled to the coupling nut ( 22) to permit the coupling nut to be rotated for tightening until a predetermined torque is reached, whereupon the sheath freely rotates about the tightened coupling nut.
