Patent ID: 8137132

Claim:
An electrical signal connector, comprising: a locknut made of metal, said locknut comprising a center hole axially extending through opposing front and rear sides thereof, an inner thread extending around an inside wall thereof within said center hole, an orifice defined in the rear side thereof in communication with one end of said center hole, and a retaining portion located on the front side thereof around said center hole; a cylindrical casing made of an elastic material, said cylindrical casing comprising an axial hole, a mounting base located on one end thereof around said axial hole and adapted for fastening to the retaining portion of said locknut and a mounting hole defined in said mounting base in communication with said axial hole; a core tube inserted into the center hole of said locknut and the axial hole of said cylindrical casing, said core tube comprising an axial hole extending through opposing front and rear sides thereof for receiving the center conductor and inner dielectric insulator of a coaxial cable, a barbed flange located on the front side around the axial hole thereof for engaging the braided metal wrapper of the coaxial cable, a first tubular wall axially connected between a stop flange and said barbed flange around the axial hole thereof, a packing portion connected between said first tubular wall and said stop flange around the axial hole thereof for engaging into the mounting hole of said mounting base of said cylindrical casing and a second tubular wall axially connected between said stop flange and said first tubular wall around the axial hole thereof, and a hooked portion extending around the periphery between said first tubular wall and said second tubular wall; and a barrel mounted on said cylindrical casing, said barrel comprising a coupling hole adapted for receiving said cylindrical casing, and a contracted inner wall portion adapted for compressing said cylindrical casing, wherein said locknut further comprises a beveled abutment face located on an outer side of said stepped shoulder; said cylindrical casing further comprises a beveled abutment face located on an outer side of said mounting base and abutted against the beveled abutment face of said locknut.
