Abstract: A signal line connector includes a locknut, a hollow cylindrical casing, which has a coupling neck extended from one end thereof and fitted into the locknut, a locating barrel fitted into the other end of the casing, the locating barrel having a pressure collar and an outside annular flange extended around the periphery thereof for engaging into the hollow cylindrical casing to force the locating barrel to deform at an amount subject to the size of the signal line used, the pressure collar and the outside annular flange of the locating barrel having different outer diameters, and an outside annular groove defined between the pressure collar and the outside annular flange for buffering and compensating the deformation, and a center holding down tube mounted in the casing and secured to the locknut by the casing for holding down a tubular outer conductor and an outer insulative layer of a signal line against the inside wall of the locating barrel, keeping a center conductor of the signal line axially suspended

Abstract: A coaxial cable connector is disclosed to include a first connecting member threaded onto a matching coaxial cable connector (jack), a second connecting member sleeved onto a coaxial cable, a locating barrel mounted on the outer end of a tube of conducting material of the coaxial cable that is turned backwards, and a center holding down member mounted inside the first connecting member to separate a central conductor of the coaxial cable from the tube of conducting material and forced by the first connecting member to squeeze the tube of conducting material in a stepped center through hole of the second connecting member.
