Definitions

  • the invention relates to an electrical conductor according to the preamble of patent claim 1.
  • Such a conductor is used for example in motor vehicles, for example in wiring or sensor cables. However, it is basically usable wherever electrical power or data is to be transmitted.
  • the conductor For use in motor vehicles, the conductor must be well bendable, flexible and resistant to tension and be able to withstand combined mechanical loads in special applications, because lines equipped with such a conductor in the motor vehicle during operation are constantly exposed to vibrations and shocks.
  • the well-known leader after the DE 10 2004 041 452 A1 has a trained as a tensile element, non-metallic core.
  • a first layer of copper existing wires with a circular cross section stranded close to lying around and above the first layer
  • a second layer of likewise consisting of copper wires is stranded with a circular cross-section whose diameter and number are such that If the wires are close to each other, a nearly smooth outer surface of the conductor results as a support for an insulation to be applied to the same.
  • This ladder has proven itself in practice.
  • the US 2003/0037957 A1 describes an electrical conductor consisting of seven wires of soft copper, which are stranded together to form a strand.
  • This leader should be used for moving parts and in particular have a high conductivity.
  • the breaking strength of the wires is 220 MPa or 220 N / mm 2 . They can be stranded with a lay length of 15 x D, where D is the diameter of the conductor.
  • the known electrical conductor according to the above-mentioned WO 2007/015345 A1 has a core of seven stranded steel wires and a core surrounding layer of twelve copper wires. This conductor should have compared to known conductors reduced dimensions.
  • the steel wires have a breaking strength of 920 MPa and 920 N / mm 2 or higher, and the breaking strength of the copper wires is 220 MPa and 220 N / mm 2 or higher, respectively.
  • the invention has for its object to improve the above-described conductor in terms of tensile strength and vibration resistance and to make so that it is suitable for connection of contact elements by crimping.
  • This ladder meets all mechanical requirements, as they are made for example for its use in motor vehicles, in the long run. It is resistant to tension by the steel wires without tensile core element and also resistant to bending, torsion and vibration when using high-strength steel wires.
  • the good bendability of the conductor is on the one hand ensured by the dimensionally stable concentric structure of the two roped-up layers and on the other hand by their short stranding length.
  • the conductor is also well suited for the electrically conductive connection of contact elements by crimping due to its special construction.
  • the first layer of the conductor in a preferred embodiment consists of high-strength steel wires
  • they can be mechanically formed by a known in the steel rope production preforming process of the individual steel wires or in a post-forming process of the roped-up layer by rolling mechanical stresses are reduced in the finished conductor, whereby in addition to the good flexibility of the conductor and a swirl freedom is given the same.
  • the conductor L has a central core 1, around which in a first layer 2 steel wires 3 are wound around. Above the first layer 2, a second layer 4 is arranged, which consists of copper wires 5 which are wound around the steel wires 3.
  • the conductor L may be surrounded by an insulation 6 produced, for example, by extrusion and / or winding. But it can also be further redistributed with at least two further, identically constructed conductors to a stranded undverseilt.
  • the core 1 is a wire made of soft annealed during a drawing process, preferably oxygen-free copper. It has a breaking strength of at least 210 N / mm 2 .
  • the core 1 can be designed as a bare copper wire. But it can also be tinned, silvered or nickel plated.
  • the steel wires 3 have a breaking strength of between 800 N / mm 2 and 2200 N / mm 2 . They can be tinned with advantage.
  • the steel wires 3 are made of stainless steel.
  • the copper wires 5 have a breaking strength of between 250 N / mm 2 and 400 N / mm 2 . Like the wire of the core 1, they can be designed as bare wires or tin-plated, silver-plated or nickel-plated.
  • Steel wires 3 and copper wires 5 can be stranded with the same direction of impact, but also with opposite direction of impact on their respective surface. They can also be applied with advantage under the same stranding angle.
  • the lay length of the copper wires 5 in the second layer 4 is between 8 ⁇ D and 18 ⁇ D.
  • D is the diameter of the conductor L over the second layer 4.
  • a stranding process in which the steel wires 3 and the copper wires 5 run from individual coils is performed, for example, on a tubular stranding machine.
  • the wires are thereby roped with a reverse rotation of about 90%.
  • the two layers 2 and 4, and thus also the conductor L, are already largely free of mechanical stresses as a result of such preforming.
  • Such a stranding process is advantageously used for conductors L that are subjected to high mechanical stresses in terms of bending, torsion and vibration during operation.
  • steel wires 3 with a breaking strength between 800 N / mm 2 and 1200 N / mm 2 can be used.
  • Such steel wires 3 can be pulled down on multi-wire drawing systems simultaneously and wound together in parallel. They can be tin-plated or, in the case of thermally highly stressed conductors L, preferably consist of stainless steel.
  • the starting material for these steel wires may each be bars of mild steel, which are pulled down in a coarse drawing process in each case to a Vorziehdraht and then tinned in a galvanic process or in a Feuerverzinnprozeß.
  • the tinned steel wires 3 still have a remaining tin layer thickness of at least 0.5 .mu.m.
  • the breaking strength of the steel wires is increased by the drawing process itself to the desired final value of 800 N / mm 2 to 2200 N / mm 2 .
  • the stranding process for such a conductor L can be done in a single work process with, for example, three tangential feed bobbins via a high-speed ironing machine in a known Doppelschlagverseiltechnik.
  • a second coil On one of the coils of the copper wire 1 is wound, a second coil has, for example, six parallel wound steel wires 3 and the third coil, for example, twelve parallel wound copper wires 5.
  • Such a manufactured conductor L can be fed directly to subsequent processing without subsequent mechanical processing, so for example be provided with the insulation 6.
  • a conductor L can be used for example in the wiring technology of motor vehicles as a single-core or as a multi-core cable in the conductor cross-sectional area between 0.25 mm 2 and 2.5 mm 2 .
  • the use of six steel wires 3 in a 19-wire conductor L reduces the electrical conductivity of the latter in comparison to a copper conductor of the same dimensions, the breaking strength of the conductor L can be doubled compared to a copper conductor of the same cross section. This is advantageous in the short in this application ladders noticeable in which an increased DC resistance, for example, for a signal transmission is insignificant.
