1. A connector for coupling an end of a coaxial cable to a terminal, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, a braided shield surrounding the dielectric, and a jacket surrounding the braided shield, the connector comprising:
- a hollow body comprising a rear end, a front end, and an internal surface extending between the rear and front ends of the body, the internal surface defining a longitudinal hole;
a compression ring comprising a rear end, a front end surrounding the hollow body, and an inner surface defining a longitudinal hole extending between the rear and front ends of the compression ring;
a tubular post disposed at least partially within the longitudinal hole of the hollow body, the post comprising a tubular shank having a rear end, an inner surface and an outer surface, and wherein the outer surface of the tubular shank and the internal surface of the body define an annular cavity therebetween; and
a deformable gripping ring disposed between the hollow body and the inner surface of the compression ring, the gripping ring comprising a rear end, a front end, an outer surface, and an inner surface;
wherein the compression ring is axially movable over the hollow body between a rearward position and a forward position;
wherein, in the rearward position, the inner surface at the rear end of the gripping ring has a rear inner diameter, and the inner surface at the front end of the gripping ring has a front inner diameter; and
wherein, in the forward position, the gripping ring is compressed between the hollow body and the compression ring, the rear end of the gripping ring has a reduced rear inner diameter less than the rear inner diameter, and the front end of the gripping ring has a reduced front inner diameter less than the second front diameter.
