Definitions

  • the invention relates to a cable system, particularly a cable having several conductors and a connector for it.
  • An example of such a cable is a so-called flexible flat cable having several flexible conductors that extend parallel to each other.
  • the conductors are accommodated in an insulating sheath that keeps the flexible conductors separated from each other.
  • the conductors and the jacket extend in a straight plane.
  • Connectors so-called Insulation Displacement Connectors that are called IDC connectors in short, can be connected to said cable.
  • the cable is accommodated in the connector at the desired location, wherein conductive clamps or pins of the connector locally cut through the insulation sheath to get into electrically conductive contact.
  • Flexible flat cables with IDC connectors are for instance used for within an electronic appliance electrically coupling spaced apart printed-circuit boards to each other.
  • the conductors are then used for the electric energy supply as well as the various control currents, wherein the IDC connectors connect to all conductors.
  • the use of flexible flat cables is limited (by law) because of the limited conducting cross-section, as a result of which the cable can only have a limited maximum length in practice does not meet the requirements within buildings or utility construction.
  • the invention provides a cable comprising an outer jacket and considered immediately consecutively adjacent to each other a first, a second and a third conductor that extend within the outer jacket substantially parallel to each other and at substantially fixed mutual distances, wherein the conductors are each built up with an insulating sheath of electrically insulating material in which only one singular solid core of electrically conductive material is accommodated, wherein considered in a cross-section transverse to the longitudinal direction of the cable the outer contour of the outer jacket at the location of the conductors is situated higher than between the conductors for at the outer side of the outer jacket visually and palpably indicating the location of the conductors, wherein the conductors extend in a notional common straight plane that defines a plane of symmetry for the outer contour, wherein the intermediate distance between the first and the second conductor is larger than the intermediate distance between the second and third conductor.
  • the conductors extend in a straight plane, as a result of which there is provided a flat cable of which the conductors each have a solid core having a relatively low internal resistance.
  • the flat cable can be laid fittingly in complementary shaped inlay channels of a connector, wherein the symmetry in the outer jacket on the one hand and the differences in the intermediate distances on the other hand here impose that laying in is only possible in two positions. The difference in these positions only is that the flat cable has been turned around about its latitudinal axis. In both cases the conductors therefore only fit into the for that purpose complementary shaped inlay channels of the connector, as a result of which connection differences onto the various conductors can be counteracted.
  • the cable particularly suitable to be used within buildings or in utility construction, wherein the three conductors can be used for the earth wire, the neutral wire and a 220-240 Volt phase wire, respectively.
  • the earth wire can in that case not be interchanged with the phase wire.
  • the shape of the outer contour above the first conductor differs from the shape of the outer contour above the second and/or third conductor. This difference in shape has a supplementary effect on the difference in distance between the first and second conductor, as a result of which laying in the cable in a forced manner into the wrong inlay channels of the connector can be counteracted.
  • the invention furthermore provides a cable comprising an outer jacket and considered immediately consecutively adjacent to each other a first, a second and a third conductor that extend within the outer jacket substantially parallel to each other and at substantially fixed mutual distances, wherein the conductors are each built up with an insulating sheath of electrically insulating material in which only one singular solid core of electrically conductive material is accommodated, wherein considered in a cross-section transverse to the longitudinal direction of the cable the outer contour of the outer jacket at the location of the conductors is situated higher than between the conductors for at the outer side of the outer jacket visually and palpably indicating the location of the conductors, wherein the conductors extend in a notional common straight plane that defines a plane of symmetry for the outer contour, wherein considered transverse to the plane of symmetry the shape of the outer contour above the first conductor differs from the shape of the outer contour above the second and/or third conductor.
  • the conductors extend in a straight plane, as a result of which there is provided a flat cable of which the conductors each have a solid core having a relatively low internal resistance.
  • the flat cable can be laid fittingly in complementary shaped inlay channels of a connector, wherein the symmetry in the outer jacket on the one hand and the differences in the shapes on the other hand here impose that laying in is only possible in two positions. The difference in these positions only is that the flat cable has been turned around about its latitudinal axis. In both cases the conductors therefore only fit into the for that purpose complementary shaped inlay channels of the connector, as a result of which connection differences onto the various conductors can be counteracted.
  • the cable particularly suitable to be used within buildings or in utility construction, wherein the three conductors can be used for the earth wire, the neutral wire and a 220-240 Volt phase wire, respectively.
  • the earth wire can in that case not be interchanged with the phase wire.
  • the intermediate distance between the first and second conductor is larger than the intermediate distance between the second and the third conductor.
  • This difference in distance has a supplementary effect on the difference in shape above the first and second conductor, as a result of which laying in the cable in a forced manner into the wrong inlay channels of the connector can be counteracted.
  • the cable comprises within the outer jacket adjacent to the third conductor considered immediately consecutively adjacent to each other a fourth conductor and a fifth conductor that extend within the outer jacket substantially parallel to each other and at substantially fixed mutual distances, wherein the conductors are each built up with an insulating sheath of electrically insulating material in which only one singular solid core of electrically conductive material is accommodated, wherein the outer contour of the outer jacket at the location of the conductors is situated higher than between the conductors for at the outer side of the outer jacket visually and palpably indicating the location of the conductors, wherein the conductors extend in the notional straight plane that defines the plane of symmetry for the outer contour.

  • the outer jacket envelopes the first conductor, the second conductor, the third conductor and preferably the fourth conductor and the fifth conductor each individually and fully in circumferential direction.

  • the holes can be used as length measure index for the cable when the first long-holes and/or the consecutive bridge section segments mutually have substantially the same intermediate distances. In that way a length of cable roughly having the correct length can be measured and taken from a stock.
  • the first long-holes are longer than the bridge section segments.
  • a number of the bridge section segments are provided with one or several second holes that in the longitudinal direction of the cable are shorter than the first holes.

  • the first bridge section comprises interruptions to provide in a series of first bridge section segments divided over the length of the cable, which first bridge section segments have substantially equal intermediate distances one to the other.
