Claim 1
Independent Claim
290 words
A coaxial cable connector having a wedge for receiving and securing said coaxial cable in said connector, said coaxial cable having an inner conductor, an insulator surrounding said inner conductor and an outer conductor surrounding said insulator, said connector comprising a wedge-nut sub-assembly, said wedge-nut sub-assembly comprising a wedge-nut and an inner ferrule, said wedge-nut having a substantially straight inner cylindrical aperture terminating in an outward forward flare, said ferrule having a shape complementary to the inner aperture of said wedge-nut, said ferrule terminating in an outward flare at its front which faces the outward forward flare of said wedge-nut, said ferrule and said wedge-nut separated by an annular space permitting rotation of said ferrule with respect to said wedge-nut, said outward flare of said ferrule adapted to press the outer conductor of said coaxial cable against said wedge, said connector further comprising a plug sub-assembly comprising a body adapted to be threaded onto said wedge-nut, said connector being assembled as said body and wedge-nut are drawn together pressing said outer conductor against said wedge by said ferrule as said wedge-nut is rotated in said body, said ferrule expanding into said annular space to bear against said wedge nut when said connector is assembled to provide a barrier to moisture entering said connector from the rear of said wedge-nut sub-assembly, wherein the body of said plug sub-assembly terminates in a forward shoulder, a connector nut rotatably connected to said body by spinning a rear portion thereof over said forward shoulder to rotatably capture said body, wherein said plug sub-assembly comprises an outer contact having a rear flange, said body being connected to said outer contact by spinning a front flange portion over said rear flange to capture said outer contact.
Claim 2
Dependent Claim
290 words
A coaxial cable connector having a wedge for receiving and securing said coaxial cable in said connector, said coaxial cable having an inner conductor, an insulator surrounding said inner conductor and an outer conductor surrounding said insulator, said connector comprising a wedge-nut sub-assembly, said wedge-nut sub-assembly comprising a wedge-nut and an inner ferrule, said wedge-nut having a substantially straight inner cylindrical aperture terminating in an outward forward flare, said ferrule having a shape complementary to the inner aperture of said wedge-nut, said ferrule terminating in an outward flare at its front which faces the outward forward flare of said wedge-nut, said ferrule and said wedge-nut separated by an annular space permitting rotation of said ferrule with respect to said wedge-nut, said outward flare of said ferrule adapted to press the outer conductor of said coaxial cable against said wedge, said connector further comprising a plug sub-assembly comprising a body adapted to be threaded onto said wedge-nut, said connector being assembled as said body and wedge-nut are drawn together pressing said outer conductor against said wedge by said ferrule as said wedge-nut is rotated in said body, said ferrule expanding into said annular space to bear against said wedge nut when said connector is assembled to provide a barrier to moisture entering said connector from the rear of said wedge-nut sub-assembly, wherein the body of said plug sub-assembly terminates in a forward shoulder, a connector nut rotatably connected to said body by spinning a rear portion thereof over said forward shoulder to rotatably capture said body, wherein said plug sub-assembly comprises an outer contact having a rear flange, said body being connected to said outer contact by spinning a front flange portion over said rear flange to capture said outer contact.
Claim 3
Dependent Claim
64 words
A coaxial cable connector as claimed in claim 1, wherein said contact wedge sub-assembly comprises said wedge having a forward counterbore forming a seating surface, an insulator having a shoulder portion inserted in said seating surface and a stepped down forward cylindrical section, and a center contact having a hook for fixedly holding said center contact in said insulator of said contact wedge sub-assembly.
Claim 4
Dependent Claim
47 words
A coaxial cable connector as claimed in claim 1, wherein said connector comprises a center contact for receiving the center conductor of said coaxial cable, said center contact comprising a tined receptacle which is crimped onto said center conductor providing a field serviceable connector assembleable without solder.
Claim 5
Dependent Claim
133 words
A plug sub-assembly for a coaxial cable connector formed of screw machine parts, the plug sub-assembly comprising a body having a stepped opening therethrough terminating in a flat front surface, a front counterbore formed in said flat front surface forming a front cavity, a one-piece insulator seated in the cavity, the one-piece insulator having a front flat surface with a central aperture therethrough enabling a center contact of said connector to pass therethrough, an outer contact electrically coupled and fixedly connected to the body, the outer contact having a flat rear flange bearing against the flat front surfae of the body and the flat front surface of the insulator, the body comprising a forwardly disposed flange spun over the flat rear flange of said outer contact to capture the flange and outer contact.
Claim 6
Dependent Claim
133 words
A plug sub-assembly for a coaxial cable connector formed of screw machine parts, the plug sub-assembly comprising a body having a stepped opening therethrough terminating in a flat front surface, a front counterbore formed in said flat front surface forming a front cavity, a one-piece insulator seated in the cavity, the one-piece insulator having a front flat surface with a central aperture therethrough enabling a center contact of said connector to pass therethrough, an outer contact electrically coupled and fixedly connected to the body, the outer contact having a flat rear flange bearing against the flat front surfae of the body and the flat front surface of the insulator, the body comprising a forwardly disposed flange spun over the flat rear flange of said outer contact to capture the flange and outer contact.
Claim 7
Dependent Claim
21 words
A plug sub-assembly for a coaxial cable connector as claimed in claim 4, wherein said outer contact comprises a hat shape.
