Locking coupling
First Claim
1. A locking coupling comprisinga body having a plurality of radially outwardly protruding teeth;
- a first collar rotatably mounted on said body and having an opening at one end;
a pawl having at least one inwardly protruding tooth suitable for engagement with said teeth on said body,said tooth extending through said opening in said first collar in alignment with said teeth;
a locking collar mounted on said first collar for movement between various positions;
said locking collar in one of said positions causing at least one tooth of said pawl to engage the teeth on said body whereby to resist movement of said first collar relative to said body.

Abstract
A locking coupling primarily for backshell connectors includes basically a main cylindrical body through which wires pass to an electrical connector, a coupling collar for connecting the backshell to the connector and a locking collar in one position permitting the coupling collar to rotate relative to the main body and in a second position locking this coupling collar to the main body, the main body having a circumferential ring of radial and axially extending teeth, a pawl having teeth carried by the coupling collar in alignment with the teeth of the main body, the locking collar forcing the teeth of this pawl into tight engagement with the teeth of the main body in the locking position.

4. A locking coupling comprising
a hollow, cylindrical coupling collar having adjacent one end a structure for coupling the collar to a further entity, said coupling collar having a circular skirt at its other end with at least three generally and circumferentially spaced rectangular recesses in the end of the skirt, a locking collar coaxial and rotatable about said coupling collar and having a key dimensioned to fit into two of said recesses in said coupling collar, a cylindrical body having formed on an outer surface thereof a plurality of radial, axially extending teeth, said collars disposed about and coaxial with said cylindrical body such that a third one of said recesses is disposed in radial alignment with said teeth, a toothed pawl disposed in said third recess over said teeth on said cylindrical body, said locking collar having an internal circumferential rim disposed about and in circumferential alignment extending with said pawl and having a radial recess therein, said recess upon being located over said pawl permitting the pawl to rise and fall relative to said teeth on said cylindrical body to provide a ratcheting effect upon rotation of said collars about said cylindrical body, said rim having a non-recessed region, said pawl forced into locking engagement with said non-recessed region of said rim being disposed over said pawl whereby to prevent rotation of said collars about said cylindrical body.

6. A locking coupling comprising
a coupling collar having at one end a structure for coupling to a further body and adjacent a second end at least one recess, a locking collar coaxial with and rotatable about said coupling collar, a pawl disposed between said collars, a cylindrical body having a circumferential ring of radial axially extending teeth, said collars disposed about said cylindrical body such that said one recess in said coupling collar is aligned with said teeth, said pawl having at least one tooth extending through said at least one recess in alignment with said teeth, said locking collar having an internal configuration such that in one position relative to said coupling, said at least one tooth is in firm contact with said teeth and in a second position relative to said coupling collar said at least one tooth may move out of firm engagement with said teeth.

10. A locking coupling comprising
a cylindrical body, a hollow, cylindrical coupling collar rotatably mounted on said body, and having adjacent one end a structure for coupling the collar to a further body, a locking collar coaxial about said coupling and possessing a member to transmit a torque to said coupling, a locking means to prevent said coupling collar from rotation about said body, an engagement means to activate said locking means, a disengagement means to deactivate said locking means, said disengagement means being initiated by an applied torque to said locking collar, said engagement means and said disengagement means effecting engagement and disengagement, respectively, by applying torque thereto in opposite directions.
