Definitions

  • the invention relates to a conductor for electrical cables, which consists of a plurality of stranded individual wires.
  • Such conductors also referred to as conductor cables, are known for all types of electrical cables for the transmission of electrical current and signals.
  • a field of application of such cables is for example the automation technology with robots and other mobile devices.
  • the cables and their conductors are constantly bent back and forth and twisted by up to 185 ° / m in both directions of rotation.
  • These requirements are met by known cables of conventional construction and relatively small cross-sections of conductors.
  • modern devices require a power supply with higher currents and cables, which also survive torsions by angles of for example 360 ° / m and more unscathed.
  • the invention has for its object to make the above-described conductor so that it is both suitable for transmitting higher currents on the one hand and on the other hand remains functional even with large torsion angles of more than 360 ° / m.
  • the electrically effective cross-section of this conductor is variable depending on the number of stranding elements or on the number of existing layers of stranding elements to predetermined currents. It can be easily made conductors with large cross-sections, for example, 10 mm 2 and more.
  • the ladder does not have a central stranding element, which in known ladders is easily destroyed by torsion as the first part.
  • the trouble-free twistability of the conductor is thereby already improved.
  • the improved twistability of the conductor is largely due to the different stranding directions of stranding elements and basic elements which ensure that the conductor as a whole survives large torsion angles of up to 540 ° / m in both directions of rotation without damage.
  • the stranding elements of the individual layers of the conductor can advantageously be stranded at the same stranding angle.
  • the core of the basic elements consists of a metal-free, deformable central element, around which a number of steel wires are arranged all around.
  • a conductor L1 consisting of twelve stranding elements VS is shown.
  • the structure of the stranding elements VS goes out Fig. 2 out.
  • a stranding element VS has according to the in Fig. 2 illustrated embodiment, a core 1 and six umverseilte around the same basic elements 2.
  • the core 1 consists of a deformable in the radial direction, ie compliant material. It is constructed, for example, of polyaramid yarn or carbon fiber yarn.
  • a base element 2 consists of a multiplicity of metallic individual wires, in particular of copper wires, which are stranded together, for example, in the direction of the arrow P1.
  • the basic elements 2 can be wound in the direction of the arrow P2 around the core 1, which is opposite to the stranding direction (arrow P1) of the individual wires. However, the stranding directions of individual wires and basic elements 2 can also coincide when the basic elements 2 are stranded without reverse rotation.
  • the stranding elements VS are in the conductor L1 after Fig. 1 arranged in two layers one above the other. In this case, in a first layer, three stranding elements VS are stranded together in a stranding direction corresponding to the arrow P3. This stranding direction is in any case opposite to the stranding direction of the basic elements 2 according to arrow P2. In a second position are according to Fig. 1 9 stranding elements VS are twisted around the first layer, in the same stranding direction indicated by the arrow P3 as the stranding elements VS of the first layer. The stranding direction of the stranding elements VS of the second layer is thus also opposite to the stranding direction of the base elements 2 according to arrow P2.
  • All stranding elements VS are thus stranded in the same direction in the conductor L1. They can also all be stranded with the same strand angle with advantage.
  • a conductor L1 according to Fig. 1 has an electrically effective cross section of 10 mm 2 , when the diameter of the base elements 2 and the core 1 is 0.48 mm.
  • Such a conductor L1 can be twisted with high durability also by angles of up to 540 ° / m in both directions.
  • at least one further layer of, for example, fifteen stranding elements VS can be stranded over the second layer of stranding elements VS, the stranding direction of which again corresponds to the stranding direction indicated by the arrow P3.
  • the structure of the conductor L1 described above with a total of twelve stranding elements VS and six basic elements 2 per stranding element corresponds to the embodiment shown in the drawings. Both the number of basic elements 2 and the number of stranding elements VS can also deviate from the specified values in the case of a sensible structure of the conductor L1.
  • the structure of the conductor L2 after Fig. 3 corresponds to that of the conductor L1 to Fig. 1 , but with modified stranding elements VS.
  • the stranding elements VS of the conductor L2 have as core 1 a metal-free, deformable central element 3 around which steel wires 4 are stranded.
  • the central element 3 may again consist of Polyaramidgarn or carbon fiber yarn.
  • the other structure of the stranding elements VS of the conductor L2 corresponds to that described for the conductor L1. This also applies to the structure of the conductor L2 from the twisted together in two layers stranding elements VS.
