Definitions

  • Tubular conductors are known, consisting of a single metal tape wound cylindrically, parallel to the longitudinal axis of said tape. As used in cables, these conductors offer only a poor resistance to the stresses caused by the bending required by manufacturing and laying.
  • the work of bending, on a tube causes longitudinal stresses which create a lengthening of the metal fibres in the region located outside the bend and a compression of the metal fibres in the region located inside the bend. Between these two zones, there exists a neutral zone where the metal fibres are subjected practically to no stress or strain, the strains increasing with the distance from this neutral zone in each region of the tube.
  • the division of the tape at the location of the joint increases the liability to yielding of one or the other edge.
  • Figure 1 represents the cross-section of a tubular conductor according to the invention.
  • Figure 2 is a perspective view of a tubular conductor provided with circular ribs, in accordance with the invention.
  • Figure 3 shows, in perspective view, the preparation to be given to the tape before forming the tube, to obtain the tubular conductor of Figure 2.
  • Figure 4 represents in perspective view, a tubular conductor in accordance with the invention, provided with helical ribs.
  • Figure 5 shows the preparation to be given to the tape before forming the tubular conductor according to the invention provided with helical ribs, as in Figure 4.
  • the ribs 5 are formed at intervals on a metal tape
  • a Figures 4 and 5 show a variant of the invention in which ribs such as 6 are formed in a direction inclined with respect to the edges 7 of the tape.
  • Figure 5 shows the preparation of the tape in a particular case of this arrangement, wherein some of the ribs 6 have been arranged in line with two teeth, similar ribs being interposed in the intervals between the ribs 6.
  • the off-centered ribs such as 8 become arranged along helical lines around the axis of the tubular conductor.
  • a tubular metallic conductor for coaxial pairs of telecommunication cables comprising a metallic tape rolled to a circular cylindrical shape about an axis parallel to the longitudinal direction thereof and joined along its longitudinal edges, said tape being provided with grooves, said edges being provided with teeth for maintaining said tube closed along the junction line of said edges, each of said teeth being respectively arranged in line with a groove, and wherein the bottom of each of said grooves is off-centered with respect to the axis of the basic cylindrical surface of said tube, the depth of the said grooves being greatest in the region of the surface of the conductor diametrically opposite said junction line after said tape has been formed into a tube.
  • a tubular metallic conductor for coaxial pairs of telecommunication cables comprising a metallic tape rolled to a circular cylindrical shape about an axis parallel to the longitudinal direction thereof and joined along its longitudinal edges, said tape being provided with ribs, said edges being provided with teeth for maintaining said tube closed along the junction line of said edges, each of said teeth being respectively arranged in line with a rib, and wherein the bottom of each of said ribs is off-centered with respect to the axis of the basic cylindrical surface of said tube, the depth of the said ribs being greatest in the region of the surface of the conductor diametrically opposite said junction line after said tape has been formed into a tube.
