Abstract
Abstract The disclosure concerns a cable connector for solid-insulation coaxial cables, the outer conductor of which consisting of a thin copper layer that is carried by a dielectric layer and is surrounded externally by a protective sheath of insulating material and a radial contact is established between the part of the outer conductor that is free from the protective sheath and a rigid contact sleeve surrounding said outer conductor, the contact being via a spring contact ring which at the end face is clamped at one edge in a sleeve surrounding the cable in such a manner that said ring is lifted from the outer conductor and pressed by an internally conically extending sleeve radially onto the outer conductor. The sleeve carrying the spring contact ring is constructed as slit conical clamping sleeve which acts on the plastic outer sheath radially by means of a gripping sleeve carrying an inner cone. The collet means constructed in this manner provides reliable securing even with relatively large diameter tolerances of the plastic sheath.
