Definitions

  • the present invention relates to a multi-conductor electric cable, each conductor of which can be connected in branch to an electrical contact without having to cut the cable, such connections being possible in predetermined zones of the cable, said zones being short with respect to the length separating two successive zones, and all the conductors being parallel to each other and contained in a plane.
  • Such a cable does not however provide very good protection of the loop-shaped conductors in the connection zones, the conductors in these zones being outside the envelope of the cable.
  • the object of the present invention is to provide an electrical cable making it possible to connect conductors to electrical contacts, for example insulation-displacement contacts, but ensuring better protection of the conductors in the connection areas by the fact that they do not protrude at the outside of the envelope.
  • FIG. 1 represents the general appearance of a cable according to the invention, comprising connection areas from place to place.
  • Figure 2 shows in diametrical section outside a connection area a screened cable formed of several twisted conductors.
  • Figure 3 shows the same cable in cross section outside a connection area.
  • Figure 4 shows the same cable in diametrical section in a connection area.
  • Figure 5 shows the same cable in cross section in a connection area.
  • FIG. 6 shows in diametral section a variant of the same screened cable, in which the non-insulated conductive element is arranged outside the insulated conductors.
  • Figure 7 shows the variant of Figure 6 seen in cross section.
  • Figure 8 shows in diametral section outside an area connecting a shielded flat cable.
  • Figure 9 shows the flat cable of Figure 8 seen in cross section outside a connection area.
  • Figure 10 shows in diametral section a connection area of a shielded flat cable.
  • Figure 11 shows the same connection area seen in cross section.
  • Figures 12 and 13 show in diametral section and in cross section a flat cable in which the non-insulated conductive element is kept at a precise distance from the other conductors.
  • the cable according to the invention comprises common zones 1 and from place to place connection zones 2, the current zones being of decimetric to decametric length, and the connection zones of millimeter to centimeter length.
  • the lengths of the current zones between two connection zones can be identical or different depending on the plan of the connections envisaged.
  • the current area of a cable with stranded conductors comprises two insulated conductors 3 and 4, a metal screen 6, and an insulating sheath 7.
  • the electric screen can be made up either of a tube produced using a metallic tape or a plastic tape coated with metal on one of its faces or on both, either of a braid or of a covering or of a weaving of metallic threads.
  • a drain conductor 5 is placed in contact with the screen all along the cable so as to allow a convenient connection of the screen to electrical contacts arranged at the ends or along the cable.
  • This drain conductor which is not coated with insulation, may consist of a single strand or of several strands stranded together.
  • FIGS. 4 and 5 represent a connection zone according to the invention of a cable, the screen of which is made of a metallic braid 6 completed with a drain conductor 5.
  • the elements of the braid are brought together in a conductive element 8 which is substantially filiform against which the drain conductor 5 is pressed.
  • the conductive element 8 can be made up of an insert element in contact at its ends with the sections of the screen on either side. of the connection area proper. It can also only consist of the single drain conductor 5 when the cable is provided with such a conductor.
  • the conductors are aligned in a plane with the conductive element 8, the latter being able to be disposed between the conductors ( Figures 4-5) or outside the latter ( Figures 6-7).
  • the drain conductor 5 when it exists remains in contact with the conductive element 8 connecting the elements of the screen 6.
  • FIGS. 8 and 9 represent the current area of a flat cable in which the conductors 3, 4 are arranged side by side inside the screen 6 and the insulating sheath 7.
  • the screen is preferably made of a braid or a metallic weave and there is no drain conductor.
  • connection area of such a cable shown in Figures 10 and 11
  • the conductive element 8 disposed between the insulated conductors 3, 4 connects the two ends of the screen on either side of the connection area . It is made by bringing together the conductive elements of the braid.
  • FIG. 12 and 13 illustrate the case of a cable where the separating element 9 exists in the connection areas and also in full cable.
  • connection zones of FIGS. 10 and 11 it is likewise possible to respect precise distances from the conductive element 8 with the insulated conductors 3, 4 by introducing a separator on each side of the conductive element 8.
  • the cables according to the invention are particularly well suited for the constitution of computer networks in which it is frequent to have to add or remove equipment along the lines or to modify their position, these various operations having to be able to be carried out without interrupting or even only fleetingly disrupt the operation of other equipment.

  1. Elektrisches abgeschirmtes Mehrfachleiterkabel, bei dem jeder Leiter abzweigend an einen elektrischen Kontakt angeschlossen werden kann, ohne daß das Kabel durchgetrennt werden muß, wobei solche Anschlüsse in vorbestimmten Zonen des Kabels hergestellt werden, wobei die Zonen relativ zur Länge, die zwei aufeinanderfolgende Zonen trennt, kurz sind und wobei alle Leiter (3, 4) parallel zueinander verlaufen und in einer Ebene liegen,
    dadurch gekennzeichnet, daß in jeder Anschlußzone:
    a) zusätzlich zu den mit einer Isolation umhüllten Leitern (3, 4) ein nicht isoliertes Leiterelement (5, 8) vorhanden ist, das die elektrische Kontinuität der Abschirmung (6) zu beiden Seiten der Anschlußzone sowie die Möglichkeit gewährleistet, die Abschirmung abzweigend an einen elektrischen Kontakt anzuschließen; und
    b) die isolierten Leiter (3, 4) und das nichtisolierte leitende Element (5, 8) relativ zueinander in genauen und vorbestimmten Abständen angeordnet sind.
