Claim Text:
1. A fitting for anchoring and electrically connecting an external conductor to an internal conductor of a coaxial cable, where the coaxial cable includes an internal continuous strength member, the internal conductor which comprises a plurality of wire layers trimmed to different lengths, and a non-conducting, environmentally sealing jacket trimmed shorter than the shortest trimmed wire layer, said fitting comprising: an intermediate ring having a mouth at one end and a bottom having a center aperture at an opposite end, said intermediate ring having a stepped inner circular wall wherein each step is sized to accept and abut against an end of a corresponding trimmed layer of the internal conductor, and wherein said mouth of said intermediate ring has substantially the same outside diameter as the diameter of the coaxial cable; an inner ring having a socket with an entrance at one end, a base having a center opening at an opposite end, and a plurality of grooves extending away from said entrance inside said socket, wherein said socket has an internal diameter substantially equal to said outside diameter of said mouth of said intermediate ring to enable said socket to snugly fit over said intermediate ring, and wherein said center opening of said base has a diameter larger than the diameter of said center aperture of said intermediate ring; an outer ring having an inside diameter substantially equal to the outside diameter of said inner ring plus twice the thickness of the external conductor to enable said outer ring to snugly fit over the external conductor when the external conductor overlays said inner ring; and a rubber tube having an inside diameter substantially equal to the diameter of the strength member of the coaxial cable to enable said rubber tube to snugly fit over the strength cable, and an outside diameter substantially equal to said diameter of said center opening to enable said rubber tube to fit snugly inside said center opening; wherein said intermediate ring is configured to snugly fit over the inner conductor so that said steps will abut against the ends of the trimmed wires and said mouth will abut snugly and substantially flush with the trimmed end of the cable jacket; wherein said inner ring is configured to snugly fit under the external conductor and over said intermediate ring and the cable jacket so that said grooves will be adjacent to the cable jacket and said base of said inner ring will abut against said bottom of said intermediate ring; wherein said rubber tube is configured to snugly fit over the strength member and inside said center opening of said inner ring to abut against said bottom of said intermediate ring; wherein said outer ring is configured to snugly fit over the portion of the external conductor that overlays said inner ring so that, when swaged, said outer ring will compress the external conductor against said inner ring, the grooves of said inner ring will compress against and emboss into the cable jacket, and said inner ring will compress said intermediate ring against the inner conductor.
