Abstract
Abstract There is disclosed in the present application, a coaxial connector adapted to being mounted on a coaxial cable including a central conductor, a dielectric, a generally braided outer conductor and a rubber or plastic jacket. The connector of the present application includes a central cone insertable between the dielectric and the outer conductor, and an externally threaded sleeve or ferrule interiorly threaded to engage the jacket of the cable and thus provide not only a watertight joint but also resistance to withdrawal of the cable from the connector.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A coaxial connector adapted to be mounted on the end of a coaxial cable having a central conductor, a braided outer conductor, an interposed insulator and a covering sheath of yielding, flexible material, the connector comprising a central conductor and an outer conductive shell respectively connectible electrically to the central conductor and the braided outer conductor of the coaxial cable, the shell having an internally threaded rearward end portion, a bushing having a conical exterior surface adapted to being inserted between the insulator and the braided outer conductor and formed with a plurality of retaining spurs spaced apart in the direction of the axis of the bushing and an externally threaded collar engaging the threads of the shell and formed with a textured interior, tapered in generally parallel relationship with the exterior surface of the bushing for applying a clamping force to the sheath of the cable whereby the textured interior of the collar penetrates and anchors in the covering sheath.
Claim 2
Dependent Claim
161 words
A coaxial connector adapted to be mounted on the end of a coaxial cable having a central conductor, a braided outer conductor, an interposed insulator and a covering sheath of yielding, flexible material, the connector comprising a central conductor and an outer conductive shell respectively connectible electrically to the central conductor and the braided outer conductor of the coaxial cable, the shell having an internally threaded rearward end portion, a bushing having a conical exterior surface adapted to being inserted between the insulator and the braided outer conductor and formed with a plurality of retaining spurs spaced apart in the direction of the axis of the bushing and an externally threaded collar engaging the threads of the shell and formed with a textured interior, tapered in generally parallel relationship with the exterior surface of the bushing for applying a clamping force to the sheath of the cable whereby the textured interior of the collar penetrates and anchors in the covering sheath.
Claim 3
Dependent Claim
34 words
A coaxial connector according to claim 1 further characterized in that the interior of the collar is textured in a buttress profile having a generally radially oriented leading surface and an inclined trailing surface.
Claim 4
Dependent Claim
27 words
A coaxial connector according to claim 1 further characterized in that the texture on the interior of the collar has a profile arranged in a helical pattern.
Claim 5
Dependent Claim
34 words
A coaxial connector according to claim 1 further characterized in that the retaining spurs on the exterior of the bushing have a profile including a generally radial leading surface and an inclined trailing surface.
Claim 6
Dependent Claim
27 words
A coaxial connector according to claim 1 further characterized in that the interior of the collar is textured in a helical pattern having a buttress thread profile.
Claim 7
Dependent Claim
26 words
A coaxial connector according to claim 5 further characterized in that the thread profile includes a generally radially oriented leading surface and an inclined trailing surface.
Claim 8
Dependent Claim
135 words
A coaxial connector adapted to be mounted on the end of a coaxial cable having a central conductor, a braided outer conductor, an interposed insulator and a covering sheath of yielding, flexible material, the connector comprising a central conductor and an outer conductive shell respectively connectible electrically to the central conductor and the braided outer conductor of the coaxial cable, the shell having an internally threaded rearward end portion, a bushing having a conical exterior surface adapted to being inserted between the insulator and the braided outer conductor and an externally threaded collar engaging the threads of the shell and formed with an interior textured in a helically patterned buttress profile, whereby the buttress profile is indented and anchored into the covering sheath as the collar is engaged with the internal threads of the shell.
Claim 9
Dependent Claim
135 words
A coaxial connector adapted to be mounted on the end of a coaxial cable having a central conductor, a braided outer conductor, an interposed insulator and a covering sheath of yielding, flexible material, the connector comprising a central conductor and an outer conductive shell respectively connectible electrically to the central conductor and the braided outer conductor of the coaxial cable, the shell having an internally threaded rearward end portion, a bushing having a conical exterior surface adapted to being inserted between the insulator and the braided outer conductor and an externally threaded collar engaging the threads of the shell and formed with an interior textured in a helically patterned buttress profile, whereby the buttress profile is indented and anchored into the covering sheath as the collar is engaged with the internal threads of the shell.
Claim 10
Dependent Claim
26 words
A coaxial connector according to claim 7 further characterized in that the buttress profile includes a generally radially oriented leading surface and an inclined trailing surface.
