Abstract
An anti-rotation feature is disclosed for preventing inadvertent disconnection of electrical connector assemblies of the type including mating plug and receptacle shells positioned in mating relationship with a surrounding coupling nut which threadedly engages one of the members and axially engages the other to draw the same into mating relationship upon rotation of the coupling nut. An elongated rod or axle extends chordally across the interior bore of the coupling nut member, with an axially movable element positioned on the axle by a pair of centering springs. The movable element is in engagement with a series of serrations formed about the periphery of one of the electrical connector components so that the centering springs resist relative rotation between the coupling nut and connector component until the spring resistance is overcome to allow relative rotation between the coupling nut member and the connector components. The serration flank geometry is asymmetrical to enable easier rotation between the coupling nut member and connector components in the direction of rotation corresponding to coupling of the connector components. Different strength centering springs are also u…
