Coaxial cable end connector

An end connector for a coaxial cable of the type having an electrical inner conductor surrounded by and spaced inwardly from an electrical outer conductor, with dielectric insulator interposed between said inner and outer conductors, and with dielectric jacket surrounding the outer conductor, said end connector comprising:

• a tubular post having a first flange at a front end thereof and a cylindrical first sleeve at a rear end thereof, said first sleeve being externally grooved to define a plurality of circular first serrations;
• an internally threaded fastener rotatably received on the front end of said post, said fastener having a second flange adapted to coact in mechanical interengagement with said first flange;
• and
• a tubular body supported on the front end of said post at a location adjacent to said first flange, said body having a cylindrical second sleeve surrounding and spaced radially from said first sleeve to define an annular chamber therebetween, said second sleeve having an open rear end leading to said annular chamber, said second sleeve having an interior surface which tapers outwardly to a maximum diameter at the open rear end thereof and which is grooved to define a plurality of discrete axially spaced circular second serrations, said second sleeve also having a grooved exterior surface defining a plurality of axially spaced circular ribs,
• said first sleeve being adapted for insertion into an end of said cable at a position at which said first sleeve is in electrical contact with said outer conductor and electrically isolated from said inner conductor by said dielectric insulator, with said jacket being received in said chamber through the open rear end thereof and being surrounded by said second sleeve,
• said ribs being deformable into a hexagonal configuration with an accompanying inward twisting deformation of said circular second serrations toward said first sleeve and into indented mechanical engagement with said jacket.
