Abstract

A connector for coaxial cable includes a dual-grip nut having a first external gripping surface and a second external gripping surface. The smallest outer diameter of the first external gripping surface is less than the smallest outer diameter of the second external gripping surface.

Claims

1. A connector for coupling the end of a coaxial cable to a port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric surrounded by an outer conductor, and the outer conductor surrounded by a jacket, said connector comprising:

a generally cylindrical body member having a first end and a second end, the first end of said cylindrical body member comprising a central bore for accepting the end of the coaxial cable;

a coupling nut comprising a first end for rotatably engaging the second end of the cylindrical body member, an opposing second end with an internally threaded bore for engaging the port, and an annular shoulder in the form of an inward lip; and

an electrically conductive retaining ring having a front end and a back end, said conductive retaining ring disposed about said generally cylindrical body member proximate to the second end thereof and disposed within an inner surface of the coupling nut bounded in part by said annular shoulder for free spinning engagement of the coupling nut and the cylindrical body member.

2. The connector of claim 1, wherein said conductive retaining ring is installed rearward of the inward lip formed by the annular shoulder.
