Abstract:
1. A coaxial connector for use with a prepared end of a coaxial cable, the coaxial cable including an inner conductor of a first predetermined diameter, a dielectric surrounding the inner conductor, an outer conductor of a second predetermined diameter surrounding the dielectric, and a protective jacket surrounding the outer conductor, the prepared end of the coaxial cable having an end portion of the dielectric removed to expose an end portion of the inner conductor, the prepared end also having an end portion of the protective jacket removed to expose an exposed end portion of the outer conductor, the outer conductor having opposing inner and outer surfaces, the coaxial connector comprising: a. a generally tubular outer body having first and second opposing ends and having a central bore extending therethrough along a central axis between the first and second ends thereof, the first end of said outer body having an annular clamping surface for engaging an inner surface of the outer conductor of a coaxial cable; b. a back nut having an inner surface defining a central bore extending between first and second opposing ends thereof, the first end of the back nut being adapted to receive the prepared end of the coaxial cable, and the second end of the back nut capable of releasably engaging the first end of the outer body, the back nut inner surface having an internal diameter, and the first end of the back nut including an inwardly-directed flange of reduced internal diameter; c. a first dielectric disposed within the central bore of the outer body, the first dielectric having a central bore extending therethrough along the central axis of the outer body; d. a center conductor extending through the central bore of the first dielectric and supported thereby, the center conductor extending between first and second ends, the first end of the center conductor capable of receiving the inner conductor of the coaxial cable, and the second end of the center conductor extending proximate the second end of the outer body, wherein the first end of the center conductor includes a compressible female socket opening toward the first end of the outer body for receiving the inner conductor extending from the prepared end of the coaxial cable; e. a clamp ring disposed within the back nut central bore and rotatable therein, the clamp ring having an outer diameter commensurate with the internal diameter of the back nut, the clamp ring having a first end proximate the inwardly-directed flange of the back nut, and the clamp ring having an opposing second end, the second end of the clamp ring including an annular clamping surface for engaging the outer surface of the outer conductor proximate the prepared end of the coaxial cable; and f. an electrically insulative seizure compressor disposed within the first end of the outer body, the seizure compressor including a first engagement surface for engaging the outer conductor of the coaxial cable and a second engagement surface for engaging the compressible female socket, wherein engagement of the back nut onto the first end of the outer body axially displaces the seizure compressor further into the outer body, and wherein the second engagement surface compresses the female socket to seize the inner conductor of the coaxial cable; wherein the clamping surface of the outer body and the clamping surface of the clamp ring sandwich the exposed portion of the outer conductor of the coaxial cable therebetween as the back nut is engaged over the first end of the outer body.
