Abstract: A low profile swivel coupling having a main body with a hollow cylindrical bearing surface, a front swivel member internally threaded to be screwed onto a threaded bearing seated on the bearing surface and rotatable on it whereby the front swivel member rotates about bearing surface of the main body.
Abstract: The invention provides a locking coupling having a hollow cylindrical body with a circumferential ring of axially extending radial teeth, a first coaxial collar having a plurality of spring fingers extending axially therefrom with inwardly directed, axially extending teeth overlying the teeth on said body and a coaxial locking collar slidably mounted on said body between two positions and having a region overlying the spring fingers, the locking collar forcing the teeth on the spring fingers into engagement with the teeth on the body in one position and permitting the teeth to become disengaged in the other position.
Abstract: A connector accessory for electrical connectors containing a detent or locking member or members for preventing disconnection from an attached connector when the assembly is subjected to vibration, shock or other stresses. The accessory consists of a coupling and a body containing the accessory which in one form is a detent and in another form serves as a detent in one direction of rotation and a permanent or temporary lock in the other direction of rotation. The coupling is provided with screw threads to engage an accessory thread at the rear of an electrical connector and the body contains features which are required to provide proper mechanical and environmental interface characteristics to mate with various electrical connectors, i.e., teeth, splines, seals, etc.
