Expansion device for expanding outer conductor portion at end of coaxial cable, has fluid channels opening in inner circumference surface or face surface of space, where fluid is supplied or discharged into or from space over channels

摘要

The device has a receiving space (16) in which an end of a coaxial cable (20) is arranged and comprising an inner circumference surface (16a) that is arranged between an insertion opening (16b) and a face surface (16c) of the space. Fluid channels (15, 17) open in the inner circumference surface or the face surface. Fluid e.g. gas, is supplied or discharged into or from the space over the channels. A low pressure generating unit e.g. venturi nozzle, comprises a nozzle (13), which is arranged between a connector (12) for an overpressure generating unit i.e. compressor, and one of the channels.
