Abstract: A rotatable and positive lockable circular connector including a spin coupling having an axial bore therethrough; a cylindrical connection interface inserted into the axial bore of the spin coupling; and an adapter body having an internal bore into which the spin coupling is axially inserted, thereby placing the spin coupling, connection interface, and adapter body into axial alignment. The adapter body includes a shielded branch for passing conductor wires. A locking system permits selective rotation of the spin coupling in relation to the adapter body when the apparatus is in an unlocked position, and positively locks the spin coupling in relation to the adapter body when the apparatus is in a locked position. Grounding elements maintain a ground path from the branch shielding to a connector shell coupled to the spin coupling.
Abstract: A lightweight flexible conduit particularly suitable for aircraft applications for shielding electrical wire and cable from electromagnetic interference and radio frequency interference. The apparatus including an inner core of elastically deformable flexible tubing having an outside surface of helical corrugations, metalized fabric wrapped around the helical corrugations and post-formed onto the corrugated helix of the core by string, thread, or wire which pulls the fabric down into the base of the continuous trough of the corrugations, and a protective jacket. A preferred embodiment of the present invention includes an axial drain wire incorporated into the lamination and running the length of the conduit to provide lower ground path resistance.
Abstract: An assembly which prevents a nut carried by an electrical conduit from decoupling from a connector. The inner periphery of the nut near the rear end teeth which define a pair of surface portions between each pair of adjacent teeth. An adapter has a spring biased detent adapted to be received in the space between an adjacent pair of teeth or in engagement with one of the surface portions. The first surface portion of each pair of teeth extends at a relatively steep angle away from the inner periphery of the nut, and a second surface portion extends at a relatively shallow angle away from such inner periphery.
Abstract: An assembly for use in coupling a flexible conduit or electrical cable to an electrical connector when the assembly and the connector must be clocked due to the fact that the conduit or cable cannot be twisted or rotated about its central axis. The assembly includes an adapter body adapted to be coupled to the conduit or cable and a nut rotatably mounted on an adjacent end of the body, the nut having threads for coupling the body to a connector to complete the assembly. The connector is adapted to be coupled to a panel-mounted connector or to a connector coupled to a second conduit or electrical cable. The body has a clocking ring rotatably mounted within one end of the body, the ring being held against axial removal from the body and being rotatable through a limited arc. The two connectors can readily mate with each other by merely rotating the clocking ring until proper clocking alignment is assured.
