Abstract

PROBLEM TO BE SOLVED: To provide a connector which is capable of concurrently performing sandwiching operation of center conductor and external conductor by housing inside of a pressurization cylinder a clamp ring which condenes together with the movement of a pressurization cylinder and a narrow-in cylinder part of a ferrule, with which the clamp ring comes into pressure contact via the external conductor. SOLUTION: A center conductor Ca is inserted into a contact 6, a terminal of a coaxial cable C is combined with an equipment side connector in a male spiral thread 2, so that a narrow-in cylinder part 11b of a ferrule 11 is narrowed-in between an external conductor Cb and an internal insulator Cc, and a cover cylinder 3 is tightened. Thereby, a pressurization step part 18 pressurizes a pressure-receiving step part 17, a pressurization cylinder 13 advances in a direction of the male spiral thread 2, and a pressurization protrusion stripe 14 is advanced while the clamp ring 16 is pressurized, the clamp ring 16 is intervened between tapered rims of the pressurization protrusion stripe 14 and the pressure-receiving ring 15. Consequently, the ring converges according to that sprit shape, and the external conductor Cb is sandwiched between the narrow-in cylinder parts 11b of the ferrule 11.
