Filed:

Dec 18, 1979

Appl. No.:

6/104993

Inventors:

Robert W. Brush - Unadilla NY
Dee A. Werth - Nineveh NY
Alan L. Schildkraut - Sidney NY

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

H01R 13639

US Classification:

339 89R

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 used in engagement on either side of the engagement element to also produce the difference in resistance to rotation.

International Classification:

H01R 1362

US Classification:

339 89M

Abstract:

An anti-vibration arrangement for resisting unthreading rotation between a coupling nut and mated components is disclosed, consisting of a deflectable mandrel extending in a radial plane chordally across an interior bore formed in the coupling nut, which mandrel mounts a slidable ball. The mandrel passes adjacent an outer surface portion of one of the electrical connector components defining a clearance space of a smaller dimension than the ball, while the ball is axially positioned in frictional engagement with the surface portion on either side of the clearance space. Rotation of the nut is resisted only minimally in a direction tending to move the ball away from the clearance space while tending to be wedged by rotation in the opposite direction. On exertion of a turning force in the wedging direction sufficient to cause deflection of the mandrel, the ball passes through the clearance space which results in greatly reduced resistance to continued rotation in that direction enabling ready uncoupling of the connector elements.

International Classification:

H01R 13629

US Classification:

339 89M

Abstract:

A coupling member (500) comprises outer and inner sleeves (410, 310) mounted for relative corotation about a connector shell (100) and about one another for rotational movement between locked and unlocked positions relative to a coil spring (322) carried by inner sleeve (310), the coil spring (322) being compressed radially inwardly by an inner wall (406) of outer sleeve (410) to drive medial tooth (318) of a spring beam (316) into a locked relation with ratchet teeth (138) disposed around the connector shell, rotation of outer sleeve (410) to a second position registering an undercut (408) in inner surface (406) with coil spring (322), whereby the coil spring expands into a relaxed position and means (422) for normally biasing the sleeves into the locked position.

International Classification:

H01R 13623

US Classification:

339 89M

Abstract:

This invention is an anti-decoupling mechanism for an electrical connector assembly of the type having two housings (20, 50) connected together by a coupling ring (30). The invention is characterized by an annular member (10) that has a plurality of slots (11) around the periphery thereof that engages the projection (41) on each spring (40) mounted within a coupling ring (30). The annular member (10) is radially expandable to increase its diameter in response to opposing axial forces applied by the housings (20, 50) as they are drawn together by the coupling ring (30). This anti-decoupling arrangement provides a first lower pressure against the spring (40) during the initial stage of the coupling cycle and a second higher pressure against the spring during the final stage of the coupling cycle thereby reducing the wear on the anti-decoupling mechanism an increasing its effectiveness.
