A coaxial connector includes a removable back nut, an outer body, and a center conductor supported within the outer body by a dielectric. The center conductor includes a female socket for receiving an exposed inner conductor of a coaxial cable, and a compression member compresses the female socket to seize the inner conductor as the back nut is secured to the outer body. In use, a prepared end of a coaxial cable is inserted through the back nut, and the end portion of the outer conductor of the coaxial cable is flared outwardly. As the back nut is tightened onto the outer body, the flared end of the outer conductor is directly clamped between integral clamping surfaces of the back nut and outer body. As the back nut is tightened, the compression member simultaneously engages the female socket to seize the inner conductor.

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 end portion of the outer conductor, the outer conductor having opposing inner and outer surfaces, the coaxial connector comprising:a. a back nut having a central bore extending between first and second ends thereof and including a first annular clamping surface integral therewith and disposed between the first and second ends of the back nut for engaging the outer surface of the outer conductor proximate the prepared end of the coaxial cable;b. a generally tubular outer body having first and second 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 being adapted to be releasably secured to the back nut and having a second annular clamping surface integral therewith for engaging the inner surface of the outer conductor of the coaxial cable;c. wherein the first and second clamping surfaces collectively are adapted to sandwich an exposed portion of the outer conductor of the coaxial cable therebetween as the back nut is tightened onto the first end of the outer body;d. 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;e. 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 including a compressible female socket opening toward the first end of the outer body for receiving and engaging the inner conductor of the coaxial cable, and the second end of the center conductor extending generally within the second end of the outer body; andf. 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 securing of the back nut onto the first end of the outer body compresses the female socket to seize the inner conductor of the coaxial cable.2. The coaxial connector recited by claim 1 wherein securing of the back nut onto the first end of the outer body axially displaces the seizure compressor further into the outer body.3. The coaxial connector recited by claim 1 wherein:a. the central bore of the back nut includes a relatively smooth portion proximate the first end of the back nut for sliding over the protective jacket of the coaxial cable, the central bore of the back nut also including a threaded portion proximate the second end thereof; andb. the first end of the outer body including a threaded outer surface inset relative to the second clamping surface, the threaded outer surface being adapted to engage and mate with the threaded portion of the back nut.4. The coaxial connector recited by claim 1 wherein the protective jacket of the coaxial cable has an outer diameter, and wherein a portion of the central bore of the back nut proximate the first end thereof has an inner diameter commensurate with the outer diameter of the protective jacket.5. The coaxial connector recited by claim 1 wherein a portion of the central bore of the back nut proximate the first end thereof is bounded by an inner wall, and wherein the inner wall has an annular recess formed therein, the coaxial connector further including an O-ring seated within the annular recess to form a seal between the central bore of the back nut and the protective jacket of the coaxial cable.6. The coaxial connector recited by claim 1 wherein the first clamping surface formed within the central bore of the back nut is an inwardly-directed annular step.7. The coaxial connector recited by claim 6 wherein the exposed portion of the outer conductor of the coaxial cable includes a flared lip, and wherein the inwardly-directed annular step engages the outer surface of such flared lip.8. The coaxial connector recited by claim 7 wherein the inwardly-directed annular step includes a beveled surface for engaging the outer surface of such flared lip.9. The coaxial connector recited by claim 1 wherein the second clamping surface of the first end of the outer body is tapered for entering within the outer conductor of the coaxial cable and for engaging the inner surface of the outer conductor of the coaxial cable.10. The coaxial connector recited by claim 1 further including an o-ring extending about the outer body and adapted to sealingly engage the second end of the back nut when the back nut is tightened onto the first end of the outer body.11. The coaxial connector recited by claim 1 further including a front nut rotatably secured about the second end of the outer body, the front nut including an internally-threaded surface for mating with an externally-threaded mating component.12. A method of attaching a coaxial connector to a prepared end of a coaxial cable, the coaxial connector including a removable back nut, a center conductor and an outer body, 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 end portion of the outer conductor, the outer conductor having opposing inner and outer surfaces, comprising the steps of:a. removing the back nut of the coaxial connector from the outer body of the coaxial connector;b. inserting the prepared end of the coaxial cable through the back nut of the coaxial connector;c. flaring an end portion of the outer conductor of the coaxial cable;d. providing a compressible female socket on the center conductor of the coaxial connector for receiving and engaging the inner conductor of the coaxial cable;e. providing a clamping surface on the outer body of the coaxial connector integral therewith;f. providing a compression member within the outer body for selectively compressing the female socket;g. positioning the prepared end of the coaxial cable proximate to the outer body of the coaxial connector to engage the inner conductor of the coaxial cable with the female socket, and to place the clamping surface of the outer body in close proximity to the flared portion of the outer conductor of the coaxial cable, and to place the compression member in close proximity to the flared portion of the coaxial cable; andh. securing the back nut of the coaxial connector to the outer body of the coaxial connector to clamp the flared portion of the outer conductor of the coaxial cable between the clamping surface and the back nut of the coaxial connector, and to simultaneously urge the compression member into engagement with the female socket for seizing the inner conductor of the coaxial cable within the female socket.13. The method recited by claim 12 wherein:a. the back nut includes a threaded surface;b. the outer body includes a threaded surface adapted to mate with the threaded surface of the back nut: andc. the step of securing the back nut to the outer body includes the step of engaging the threaded surface of the back nut with the threaded surface of the outer body and rotating the back nut relative to the outer body to tighten the back nut onto the outer body.
