ABSTRACT:
A clamping device for securing HF fittings to coaxial cables or hollow conductors by means of a clamping sleeve surrounding the cable outer sheath or the hollow conductor sheath. The sheath is radially inwardly deformed by the clamping sleeve in such a manner that a transformation is effected which guarantees a reflection-free transition to the adjoining fitting. In the end portion of the cable or hollow conductor the outer sheath is engaged radially so that it is compressed, giving a reliable hold. The cable sheath is thus deformed in a definite manner so that at the point of entry into the fitting it has a predetermined size, said deformation gradually or abruptly decreasing towards the cable in a transformation portion. This deformation can be effected by suitable means, for example axial tensioning or by a two-part clamping sleeve with tangential tensioning.
