Abstract: A termination arrangement for fiber optic cables includes a precision ceramic guide press fit into a sleeve on both the socket and pin termini. The precision ceramic guide of the socket terminus is extended through a bushing and alignment sleeve, and a compression spring is positioned between the bushing and a stepped washer secured in the connector so that the bushing, sleeve, and precision ceramic guide may all be moved relative to the stepped washer upon insertion of the ceramic guide of the pin terminus into the alignment sleeve. The length of each terminus is chosen so that any grommet on an environmentally sealed connector will always fall on a portion of the body which has the same diameter for each terminus so that one grommet can be used with a variety of different size cables. A rear section of both the pin and socket terminus bodies are stepped down to provide an area for the strength member of the fiber optic cable to be terminated to.

Abstract: An anti-decoupling arrangement for an electrical connector (as well as an electrical connector incorporating such an anti-decoupling arrangement) is made up of just three operative components: a spiral lock clutch, at least one spring ring, and ratchet teeth or serrations formed on an inside surface of the coupling nut. The ratchet teeth are in the form of serrations formed into the inside diameter of a recessed area of the coupling nut in which all of the components reside, and each spring ring is a self-supporting ring that has spring cantilevers with engaging tines of a given number located around its outer circumference, the engaging tines engaging the serrations in a radial direction. The engaging tines thus provide a torque/ratchet mechanism when they glide over the radial cuts of the tooth ring in the uncoupling direction, and stay engaged which forces the spiral lock clutch to expand and slide smoothly over the plug shell with minimal torque in the coupling direction.

Abstract: An anti-decoupling arrangement for an electrical connector includes a spiral lock clutch, a spring ring, and a separate ratchet wheel or tooth ring having a plurality of radial cuts, all surrounding the connector shell and sandwiched between a flange or shoulder on the connector shell by a conventional snap ring. The tooth ring is situated in a space between the thread of the coupling nut and the flange or shoulder that forms the inner surface of a recessed area with the coupling nut. The shell includes two grooves, one for the spiral lock clutch and the other for the snap ring, that are behind the flange or shoulder towards the rear of the connector, the shell providing axial alignment of all components except the spring ring.
