US Patent 7261581 Coaxial connector and method

Disclosed is a coaxial connector consisting of a back nut, outer and inner terminals, and an insulator. The back nut is made of a single tubular piece and does not enclose any further parts. In connecting a coaxial cable to the connector, the cable is inserted through the back nut, and a portion of the outer conductor at the end of the cable is flared and shaped along a tapered clamping face of the back nut. The back nut is then axially displaced, as by threading the back nut over the outer terminal, to clamp the flared end of the outer conductor of the coaxial cable between the outer terminal of the connector and the back nut thereof.
