Locking connector
A connector includes a base and a nut which is configured to fit within and be retained within a chamber in the base. The nut is laterally inserted into the chamber via a side opening in the base and is axially displaced within the chamber between locked and unlocked positions. The nut includes a radial projection which is configured to enter into a bore in the base adjacent to the chamber when the nut is in the locked position. When the nut is in the released position, the projection is withdrawn from the bore so that the nut may be removed from the base.
1. A connector, comprising
(a) a base containing a chamber and a side opening in a surface of said base;
(b) a nut removably connected with said base and containing a threaded through opening having an axis normal to an axis of said nut and an arcuate projection arranged adjacent to said threaded through opening, whereby when a tool is arranged within said threaded through opening and rotated with respect to said nut, said nut is displaced between a locked position wherein said nut is arranged and retained within said chamber with said arcuate projection extending beyond an outer surface of said nut and engaging an inner surface of said base and an unlocked position wherein said nut is removable from said chamber via said side opening.
2. A connector as defined in claim 1 , wherein said chamber and said nut have a generally cylindrical configuration, a diameter of said nut being less than a diameter of said chamber to provide a limited amount of movement of said nut between said locked and unlocked positions.
3. A connector as defined in claim 1 , wherein said base contains a through opening which communicates with said chamber and wherein said nut includes a boss extending from an end surface thereof, said boss being arranged in said through opening when said nut is arranged in said chamber and said boss engages a surface of said base which defines said through opening when said nut is in the locked position.
4. A connector as defined in claim 3 , wherein said base contains an end opening arranged normal to said side opening and communicating with said chamber, the tool extending from said nut threaded through opening through said end opening.
5. A connector as defined in claim 4 , wherein said arcuate projection extends at least partially around said threaded through opening of said nut and enters said end opening when said nut is in the locked position.
