  • Patent number: 4469390
    Abstract: The invention is directed to an arrangement for simply and inexpensively attaching semirigid coaxial cable to suitable connectors in which the connector is provided with a sleeve having either internal fluting or cross threads. The effective internal diameter of the sleeve is only slightly greater than the external diameter of the outer conductor of the semirigid cable so that when the sleeve is crimped the flutes and/or threads bite into the outer conductor to form a connector-cable bond sufficiently resistant to pull-off, twisting and slipping, while at the same time forming a joint having an acceptably low radio signal power leakage through the crimped interface and so little dimensioning effect on the cable that transmission losses due to internal reflections are maintained acceptably low.
