Definitions

  • the present invention relates to a flat cable.
  • One of the aims of the present invention is to allow, for these electromagnetic applications, the use of flat cables.
  • the flat cable according to the invention is of the type comprising a series of flat, parallel, embedded conductors in a thickness of insulating material, said flat cable being characterized in that it is folded along a series of transverse lines so as to obtain a configuration noticeably zigzag.
  • Such a flat cable, thus bent, can replace the normally used twisted conductors.
  • the lines transverse are parallel and inclined to form, along the two edges, alternate internal acute angles.
  • Figure 1 shows a flat cable used to make twisted cables.
  • Figure 2 shows in plan the formation of lines of folding for the realization of a twisted flat cable.
  • Figure 3A is a perspective view showing the flat cable during bending.
  • Figure 3b is a plan view showing the flat cable twisted finished.
  • Figure 4 shows schematically in plan a variant of making a flat cable twisted during its development.
  • Figure 5A and 5B respectively show the realization and the twisted flat cable obtained from folding shown in figure 4.
  • FIG. 1 there is shown a flat cable 1 with two faces 1a and 1b and comprising a series of conductors parallel dishes 2 embedded in a thickness of insulating material.
  • Lines 4 and 5 delimit between them a strip 9, lines 5 and 6 strip 10, lines 6 and 7 a strip 11 and lines 7 and 8 a strip 12, the reference 13 designating an extreme band.
  • the flat cable is bent along line 4 so that tape 9 is applied against face 1a and folded in opposite direction along line 5 so that the side 1b of the strip 10 is folded against the face 1b of the strip 5.
  • the flat cable is bent along line 6 so that the strip 11 is, on the side of the face 1a, in part applied against the strip 10 on the side of the face 1a, while along line 7, the ribbon cable is bent so that the strip 12 is, on the side of the face 1b, applied against the strip 11 on the side of the face 1b.
  • Tape 13 is folded along line 8 and applied against the strip 12 on the side of the face 1a.
  • the flat cable can thus have a series of folds showing, after line 8, the same folds as those corresponding to lines 4, 5, 6 etc.
  • Figures 4, 5A and 5B show a variant of embodiment in which the flat cable designated in its together by the reference 15 has two faces 15a and 15b.
  • the flat cable 15 has a series of lines 16 to 20 extending parallel and transversely so to be formed, on the side of the two longitudinal edges of said cable flat, internal alternate angles 21, 22 of the order of 20 ° at 30 °.
  • the different lines delimit between them bands 23 to 28.
  • the flat cable is folded so that the strip 24, after folding along line 16, be applied by the side 15a against side 15a of the strip 23, the strip 25 after folding along line 17 against strip 24 of side of face 15a and so on, that is to say that all the strips are folded in the same direction along the fold lines.
  • This gives a substantially configuration in a zigzag whose re-entrant and salient angles can be more or less pronounced according to the inclinations given on lines 16 to 20.
