Definitions

  • the present invention relates to tubular conductors and particularly pertains to improvements in cables of the air space insulation type.
  • tubular conductors from a plurality of metal bands, more particularly as an outer conductor for high frequency cables, by providing the metal bands along their longitudinal edges with indentations at definite distances from one another.
  • the indentations of adjacent bands were preferably staggered relatively to one another. Bands provided with such indentations are prevented frombeing individually laterally displaced.
  • the object of the present invention isto provide an improvement of such tubular conductors.
  • An outer conductor constructed in the manner referred to, is pressure resisting and also very nexible, even when thethiclmess of the outer conductor is small.
  • the transverse grooves may, according to the invention, be provided with projecting parts.
  • the projections engage with the bands which abut against one another and prevent a lateral displacement between the bands, while a relative longitudinal displacement is possible in the interval between the consecutive projections.
  • An unlimited possibility of displacement in the longitudinal direction may be obtained by providthe two bands abutting against ting out portions of the transverse grooves of the other band at the abutting edge. so that the projections of the one band can slide past at these points.
  • Fig. 1 is a plan view of a cable embodying the invention with parts broken away.
  • Fig. 2 is a perspective view of the bands provided with transverse grooves and illustrating the projecting partsr
  • Fig. 3 is an end view of the conductor bands shown in Fig. 2.
  • I l is the inner conductor of a concentric high frequency cable surrounded by the supporting helices I2 of polystyrol and the polystyrol bonds i3.
  • the outer conductor consisting of preshaped bands 6l and 65, which are provided with transverse grooves 63 at short distances from one another.
  • the bands 6I and 63 are held together by a further copper band I6.
  • the bands are more clearly shown in Figs. 2 and 3 wherein the outer conductor 6
  • the projections 64 engage with the abutting tubular half 65 and prevent a lateral displacement between the two tube halves, while Y a relative longitudinal displacement is possible within the interval between the consecutive pron jections.
  • An unlimited possibility of displacement in the longitudinal direction may be obtained by providing only one of the two abutting bands with projecting parts il, and by cutting out portions of the transverse grooves of the other band $5 at the points 66, so that the projections il of the opposite band 8
  • a tubular electric high frequency conductor consisting of a plurality of metal bands stranded together and having indentations in the form of transverse grooves extending at right angles to the plane of the bands, said bands being Preeral displacement between adjacent bands.
