Abstract

A connector assembly includes an electrical connector and a sleeve. The electrical connector has opposite first and second ends. The first end is rotatable with respect to the second end and configured to couple to a mating connector. The second end is configured to terminate a cable. The sleeve has an outer gripping surface, and an inner bore for receiving the electrical connector such that the sleeve and the first end of the connector are rotatable together.

Claims

1. A connector assembly, comprising of:

an electrical connector having opposite first and second ends, said first end being rotatable with respect to said second end and configured to couple to a mating connector, said second end being configured to terminate a cable; and

a sleeve having an outer gripping surface and an inner bore that receives said first and second ends of said electrical connector, said sleeve and said first end of said connector being rotatable together with respect to said second end of said connector, and said inner bore including a retaining member configured to substantially prevent axial movement of the electrical connector with respect to said sleeve;

wherein said first end is in direct contact with said second end.

2. The connector assembly according to claim 1, wherein

said sleeve has a substantially hexagonal shape in cross-section.

3. The connector assembly according to claim 1, wherein

said outer gripping surface has a plurality of longitudinal spines extending along said sleeve.

4. The connector assembly according to claim 1, wherein

said sleeve is made of a material selected from the group consisting of rubber, synthetic rubber, neoprene, thermoplastic, thermosetting plastic, polyethylene, polypropylene, polystyrene, acrylonitrile butadiene styrene, polyethylene terephthalate, polyester, polyamides, polyvinyl chloride, polyurethanes, and polycarbonate.

5. The connector assembly according to claim 1, wherein

said first end of said electrical connector is a nut body.

6. The connector assembly according to claim 1, wherein

said sleeve has a shape substantially corresponding to a shape of said first end.

7. The connector assembly according to claim 1, wherein

said electrical connector is a co-axial connector.

8. The connector assembly according to claim 1, wherein

the retaining member is a radial flange.

9. The connector assembly according to claim 1, wherein

the sleeve engages the first end of the electrical connector by a friction fit.

10. A connector assembly, comprising of:

an electrical connector having opposite first and second ends, said first end being rotatable with respect to said second end and configured to couple to a mating connector, said second end being configured to terminate a cable; and

a non-threaded sleeve including,

an inner bore extending through said sleeve, said inner bore receiving said electrical connector, one portion of said inner bore being configured to ensnare said first end of said electrical connector, and another portion of said inner bore being configured to retain said electrical connector in said inner bore, and

an outer gripping surface.

11. The connector assembly according to claim 10, wherein

said sleeve has an elongated body having opposite ends.

12. The connector assembly according to claim 10, wherein

said sleeve has a plurality of lateral surfaces disposed adjacent to each other and meeting at adjacent edges to form a substantially hexagonal shape in cross-section.

13. The connector assembly according to claim 12, wherein

the sleeve has a first face and a second face at said opposite ends of said sleeve, the first and second faces being substantially perpendicular to said lateral surfaces.

14. The connector assembly according to claim 12, further comprising

a spine disposed at said adjacent edges of said lateral surfaces, said spine extending longitudinally along said adjacent edges between said ends of said elongated body.

15. The connector assembly according to claim 10, wherein

said sleeve is made of rubber.

16. The connector assembly according to claim 10, wherein

said electrical connector is a co-axial connector.

17. The connector assembly according to claim 10, wherein

said first end of said electrical body includes a nut body.

18. The connector assembly according to claim 10, wherein said inner bore of said sleeve has a retaining member that is a radial flange substantially preventing axial movement of said electrical connector in said inner bore.

19. A method of forming a connector assembly, comprising the steps of:

providing an electrical connector with first and second ends, the first end and the second end being adapted to be coupled to each other, the first end being rotatable with respect to the second end, the first end being configured to couple to a mating connector, and the second end configured to terminate a cable;

providing a non-threaded sleeve being configured to receive the electrical connector, the sleeve having an outer gripping surface, whereby the sleeve and the first end of the electrical connector together rotate with respect to the second end of the connector;

inserting the first end into one end of the sleeve;

inserting the second end into the opposite end of the sleeve; and

assembling the first end and the second end within the sleeve such that the first end is in direct contact with the second end.

20. The method according to claim 19, further comprising the steps of:

terminating the cable at the second end of the electrical connector.

21. The method according to claim 19, further comprising the step of:

gripping the outer gripping surface of the sleeve to rotate the first end of the electrical connector.

22. The method according to claim 19, further comprising the steps of:

abutting the first end against a retaining member in an inner bore of the sleeve; and

abutting the second end against the retaining member.
