Title: Clamping device for HF fittings of coaxial cables and wave guides - has tapering guide between max. and min. dia. tolerances
Inventor: SPINNER GEORG DIPL-ING DR-ING
IPC: H02G15/08
Filed: 1973-08-03
Abstract: The clamping device shaping collar ensures that the end of a length of corrugated waveguide or corrugated coaxial cable amtes with a suitable and fixture by tapering the end of the conductor between its max. and min. diameter tolerances so that somewhere along the taper the conductor has a diameter which mates with the hole in the end fixture, such as a flange, a component, a connector etc. The collar has its inside surface tapered and corrugated to fit the conductor corrugations. The smaller diameter, i.e. the lower tolerance, is formed at the very end of the conductor. The collar length may equal the quarter-wavelength to reduce reflections at the taper. This shaping method is not restricted to corrugated conductors, but also applies to smooth and elliptical conductors.
