LOW COST COAXIAL CABLE CONNECTOR FOR MULTIPLE CABLE SIZES
First Claim
1. A coaxial cable connector for connecting a coaxial cable to an RF port, the coaxial cable connector comprised of:
- a fastener comprising a forward end and a rearward end and including an axial bore therethrough having a shoulder proximate to the rearward end;
a tubular post comprising a central bore, a flange engaged with the shoulder in the axial bore of the fastener, a bonding region, and a tubular extension extending rearwardly from the bonding region and terminating at an annular barb;
a connector body comprising a deformable wall having an axial bore therethrough, the axial bore having a forward region joined to the bonding region of the tubular post, and a rearward region surrounding the tubular extension of the tubular post to form a first annulus; and
a compression cap movable between a first position not engaged with the connector body to a second position engaged with the connector body, the compression cap configured to receive a prepared coaxial cable, and comprising;
an integral compression ferrule comprised of a forwardly extending length of ferrule wall bounded by an inner bore surface, a forward end, and an outer surface;
a bottom region extending radially outwardly from a rearward end of the forwardly extending ferrule wall; and
a sleeve wall extending forwardly from the bottom region, terminating at a forward end, and forming a second annulus between the sleeve wall and the ferrule wall;
wherein when the compression cap is advanced axially from the first position to the second position, the rearward region of the connector body is received in the second annulus and forms a constriction between the annular barb of the tubular post and the inner bore surface of the ferrule wall.

Abstract
A coaxial cable connector for connecting a coaxial cable to an RF port, wherein the cable connector is comprised of a connector subassembly and a compression cap. The connector subassembly is of simple inexpensive construction and is comprised of a fastener, a tubular post, and a connector body. The connector subassembly may function a stand-alone crimpable cable connector. The compression cap may be placed over the end of a coaxial cable, and compressed onto the connector subassembly to secure a prepared end of the cable within the compressed and assembled connector.

8. A method for terminating an end of a coaxial cable within a coaxial cable connector, the coaxial cable comprising a center conductor surrounded by an insulator, a conductive shield surrounding the insulator, and an insulative jacket surrounding the conductive shield, the method comprising:
-
providing the coaxial cable connector comprised of a fastener comprising a forward end and a rearward end and including an axial bore therethrough having a shoulder proximate to the rearward end;
a tubular post comprising a central bore, a flange engaged with the shoulder in the axial bore of the fastener, a bonding region, and a tubular extension extending rearwardly from the bonding region and terminating at an annular barb;
a connector body comprising a deformable wall having an axial bore therethrough, the axial bore having a forward region joined to the bonding region of the tubular post and a rearward region surrounding the tubular extension of the tubular post to form a first annulus; and
a compression cap movable between a first position not engaged with the connector body to a second position engaged with the connector body, the compression cap configured to receive a prepared coaxial cable, and comprising an integral compression ferrule comprised of a forwardly extending length of ferrule wall bounded by an inner bore surface, a forward end, and an outer surface, a bottom region extending radially outwardly from a rearward end of the forwardly extending ferrule wall, and a sleeve wall extending forwardly from the bottom region and forming a second annulus between the sleeve wall and the ferrule wall;inserting the end of the coaxial cable through the compression cap; making a prepared end of the coaxial cable by stripping a first extent of insulator, conductive shield, and insulative jacket to expose a length of center conductor, stripping a second extent of insulative jacket to expose a length of conductive shield, and folding back the exposed length of conductive shield axially along the insulative jacket; inserting the prepared end of the coaxial cable into the rearward region of the connector body, such that the central bore of the tubular post receives a portion of the center conductor and insulator, and the exposed length of conductive shield is disposed in the first annulus; and moving the compression cap forwardly along the coaxial cable such that the rearward region of the connector body is received in the second annulus and forms a constriction between the annular barb of the tubular post and the inner bore surface of the ferrule wall, binding the cable between the ferrule wall and the tubular extension of the tubular post. - View Dependent Claims (9, 10)
