End-processed coaxial cable structures and methods for producing the same

Abstract

In an end-processed coaxial cable structure in which at least one end of a coaxial cable assembly formed by paralleling a plurality of coaxial cables is cut, jacket layers are removed in the vicinity of a cut end portion thereof to expose shielding layers, the shielding layers are further cut to a determined length to expose dielectric layers, the exposed shielding layers are put between metal ground bars to cover them, and the metal ground bars are fixed with solder onto the shielding layers and the dielectric layers arranged at determined intervals, cut ends of the shielding layers exist substantially inside the metal ground bars and are not projected to the outside thereof. The coaxial cable structure is produced by removing the jacket layers in the vicinity of the cut end portion to expose shielding layers, cutting the shielding layers to a determined length to expose the dielectric layers, putting the exposed shielding layers between the metal ground bars to cover them in a state where the cut ends thereof are not substantially projected from the metal ground bars, and fixing the metal ground bars with solder onto the shielding layers and the dielectric layers arranged at determined intervals. The end-processed coaxial cable structure has no projection of shielding layers and no protrusion of solder from the metal ground bars, is very smooth in end faces of the metal ground bars, so that the incidence of defective products caused by the difficulty of connection thereof to a connector or occurrence of poor insulation between the shielding layers and the central conductors can be significantly decreased, and moreover, can be reduced in cost because only one pair of metal ground bars are used.
