Bending coaxial electrical connector
A bending coaxial electrical connector has a center terminal, a dielectric body and an outer conductor wherein the cover section of the outer conductor is provided with a protrusion projecting to the tubular section by means of which a corresponding bump is stamped out from the dielectric body which is then pressed against a center conductor of the coaxial cable disposed on the connecting section so as to form a secure connection between the center conductor of the coaxial cable and the connecting section of the center terminal of the coaxial electrical connector. The electrical connector is advantageous in that the various structures described above can firmly maintain the center conductor at a predetermined position on the center terminal, so the consistency and stability of the characteristic impedance of the connection is achieved.
1. A bending coaxial electrical connector comprising:
a center terminal having a connecting section for connecting a center conductor of a coaxial cable, and a contacting section for contacting a terminal of a complementary connector;
