Definitions

  • the present invention relates to electric cables for high frequency transmission and employing outer conductors formed of a tape or tapes of conducting material.
  • the present invention in order to overcome this difficulty, consists in an air spaced coaxial cable having an outer conductor of corrugated tape or tapes formed to shape with the adjacent edges of said tape or tapes abutting and in which said corrugations are deformed along the butt joint or joints so that the tape edges cross one another at an angle.
  • Fig. l is an enlarged perspective View showing a portion of a cylindrical corrugated tape according to the prior art
  • Fig. 2 is an enlarged perspective View showing a portion of a cylindrical tape in accordance with the present invention
  • Fig. 3 is a plan view of a portion of a corrugated tape according to the present invention.
  • Figs. 4A, 4B and 4C are crcss-sectional views respectively along the lines A- 3-33 and C-C of Fig. 3;
  • Fig. 5 is a broken, elevational view of a portion of a coaxial cable in accordance with the present invention.
  • Fig. "6 is an end view, partially in section, or the cable shown in Fig. -5.
  • Fig. 1 illustrates the old-type of cable previous ly mentioned from which it will be seen that in the case of a cable made from corrugated tape in the manner used up to now, the abutting edges of this tape will tend to slide over one another.
  • a method of making the tape above described would be to pass the tape between two engaging toothed rollers, in which the major portion of the two rollers gives a sine wave corrugation to the central portion of the tape, whilst the edges have the sine wave distorted in one direction on one edge and in the opposite direction on the other edge to an equal amount.
  • Figs. 3 and 4 of the accompanying drawings The form of a preferred type of corrugation is illustrated in Figs. 3 and 4 of the accompanying drawings.
  • the ridge of the corrugations formed on a flat tape are shown in Fig. 3, with the corrugations at one end displaced in one direction as at la and the corrugations at the other-end displaced in the opposite direction as at to.
  • the profiles of sections along AA, BB and CC are shown at A, B and C respectively in Fig. 4.
  • the relative dimensions are, of course, considerably exaggerated in both figures.
  • insulating spacers may be used to support the inner conductor of the cable as indicated in Figs. 5 and 6 of the accompanying drawings, in which reference numeral 1 indicates the corrugated outer conductor butt jointed at 2 and bound round with metal tape 3. Insulators 4 support inner conductor 5, which may itself form the outer conductor of a further coaxial cable.
  • a hollow tubular conductor consisting of a thin cylindrical metal tube having longitudinally abutting edges, circumferential corrugations in said tube to render it flexible, corrugations at the abutting edges of the tube being respectively longitudinally displaced in opposite directions, whereby the abutting edges cross one another and relative circumferential movement therebetween is prevented.
  • corrugations are, longitudinally, substantially sinusoidal for the greater part of the circumference of the tube, but deformed at the abutting edges to provide said crossed abutting contact.
