Abstract

A connector for a coaxial cable, includes a head portion having a recess which has one end formed with a first ring surface for establishing a contact from inside with an end zone of an outer cable conductor, and a restraint mechanism for the coaxial cable, with the restraint mechanism including a clamp bushing having a head portion side end formed with a second ring surface for clamping the end zone of the outer cable conductor from outside, and a pressure-applying member surrounding the cable and fastened to the head portion. The pressure-applying member forces the clamp bushing in the axial direction against the first ring surface to thereby clamp the end zone of the outer cable conductor between the first and second ring surfaces. In order to effect a particular high degree of contact, at least one of the first and second ring surfaces is formed with at least one annular bead jutting out in the direction of a respective area of the end zone of the outer cable conductor and defined by a height of approximately 5 to 30% of a wall thickness of the outer cable conductor.
