Definitions

  • the invention relates to an electrical conductor with an electrical contact element, in particular belonging to an interface, which has at least one electrical contact point, the conductor having a bundle of individual electrical wires.
  • the invention further relates to an electrical interface with at least one electrical conductor.
  • carbon nanostructure-based fibers in particular carbon nano tubes (CNT).
  • CNT carbon nano tubes
  • Single-wall carbon nano tubes have a density of 1.3 to 1.4 g / cm 3 and a tensile strength of approximately 30 GPa
  • multi-wall versions have a density of approximately 1.8 g / cm 3 and a tensile strength of up to 63 GPa.
  • steel has a density of around 7.5 g / cm 3 and a maximum tensile strength of 2 GPa. This means that multi-walled CNTs theoretically have a 135-times better ratio of tensile strength to density (tear length) compared to steel.
  • the invention takes advantage of the specific properties of CNB fibers, in particular CNT fibers, and in addition to very good electrical and thermal values, there is a significant reduction in the design compared to the copper-based technology currently used, so that
  • an electrical conductor with a contact element is created is, which brings high savings in terms of space, effort, weight and costs, which results in great freedom in the geometric design of associated structural units, such as housings.
  • the electrical conductor according to the invention with the electrical contact element belonging in particular to the interface has at least one electrical contact point on the contact element, the conductor having a bundle of electrical individual wires, the individual wires
  • carbon nanostructure-based fibers in particular carbon nano-tubes (CNT), and an area of each individual wire is at least one
  • the invention thus uses carbon nanostructure-based fibers to form the electrical conductor, the individual wires formed by the fibers having regions which each have a contact point on the contact element. Accordingly, the single wires have a double function, since they conduct the electrical current over their length and also form the at least one contact point in each case.
  • Each individual wire, that is to say each CNT fiber, thus has this electrical contact point as a one-piece component, which results in a simple and inexpensive design
  • the individual cores for the most part run essentially parallel to one another.
  • This parallel strand of single wires represents the electrical conductor along its length.
  • the parallelism mentioned here is present. In the area of the contact element, this parallelism is left in places.
  • Contact element has a support body around which the areas of the individual wires run in a loop.
  • the individual cores thus extend into the contact element, that is to say they are involved in regions in the formation of the contact element.
  • the loop shape mentioned results from the fact that the incoming individual wires are bent in the area of the contact element and are returned to a certain extent.
  • the support body creates the contour of the contact element and gives the loop-shaped course of each
  • the support body is a contact sleeve, the areas of the individual wires running through the interior of the contact sleeve, in particular along the inside of the contact sleeve, and - in a reversal point - around one end of the contact sleeve to the outside run.
  • the incoming bundle of the single wires widens in the area of the contact sleeve in such a way that the single wires run along the inside of the contact sleeve as they pass through the interior of the contact sleeve until they reach the reversal point which is at the end of the contact sleeve.
  • the individual cores are led around the end of the contact sleeve to the outside, preferably returned by 180 °.
  • the contact sleeve preferably has a circular cross section.
  • the areas of the individual wires are arranged distributed over the circumference of the contact sleeve. This is preferably done
  • a crimp sleeve is provided with which the positions of the individual wires are fixed in particular on the contact element.
  • this crimp sleeve is assigned to another end of the contact sleeve, preferably assigned at a distance, the crimp sleeve holding end zones of the regions of the individual wires pressed against the bundle of individual wires.
  • the incoming bundle of the single wires running to the contact element is fanned back at the reversal point and then pressed against the bundle of the single wires by means of the crimping sleeve.
  • a further development of the invention provides that at least one contact point is formed on each section of each individual wire extending through the interior of the contact sleeve and / or the at least one contact point is formed on each section of each individual wire running along the outside of the contact sleeve. This enables electrical contacting of the contact element with a further electrical element either with the sections of the individual individual wires lying inside the contact sleeve and / or with the sections of the individual wires running on the outside of the contact sleeve.
  • an electrical interface with at least one electrical conductor is provided, as described above, it is proposed that the electrical interface furthermore has at least one further electrical conductor, which is shown in FIG.
  • the contact element is constructed in the same way as the first-mentioned conductor, but instead of the contact element has a mating contact element, the contact element being plugged together with the mating contact element for electrical contact by the contact element being in the interior of the
  • Mating contact element is inserted or the mating contact element is inserted into the interior of the contact element. Both conductors are constructed in the same way. This also applies to the structure of the contact element and the counter-contact element, whereby contact element and
  • the counter-contact element is therefore basically of the same design, but is of a different size.
  • the interface thus forms a contact system which has electrical contacting of basically identical contact parts, in particular contact element and counter-contact element.
  • Embodiment shows on its left side an electrical conductor 1 with a
  • the electrical conductor 1 has a bundle 3 of individual electrical wires 4. In the figure, only two single wires 4 are marked; however, more or fewer individual wires 4 can be provided.
  • the single cores 4 are designed as carbon nanostructure-based fibers (CNB), in particular as carbon nano tubes (CNT).
  • the contact sleeve 6 has a circular cross-sectional contour. The fanning out is distributed over the circumference of the contact sleeve 6, preferably evenly distributed over the circumference.
  • the contact sleeve 6 has an inside 7 and an outside 8. Die
  • a crimp sleeve 13 is arranged, which includes end zones 14 of the areas 9 of the single wires 4 and also the bundle 3 of the single wires 4 and is crimped in such a way that the end zones 14 are held pressed against the bundle 3 of the single wires 4.
  • the crimp sleeve 13 is preferably at a distance from the contact sleeve 6 in order to enable the individual wires 4 to have an arcuate shape.
  • At least one electrical contact point 17 is formed on each section 15 of each individual wire 4 extending through the interior 10 of the contact sleeve 6.
  • a contact point 17 is also formed on each section 16 of each individual wire 4 running along the outside 8 of the contact sleeve 6.
  • the contact points 17 result from the corresponding surface areas of the electrically highly conductive single wires 4.
  • electrical insulation 18 can be provided, which preferably ends a little before the crimp sleeve 13.
  • Contact element 2 on the right side which however differs in size from the contact element 2 shown on the left side of the figure in such a way that it is possible to insert the contact element 2 on the left side into the interior of the contact element 2 on the right side for electrical contacting .
  • a double arrow 19 illustrates this.
  • the contact element 2 on the right-hand side of the figure is to be named a counter-contact element 20 to distinguish it.
  • an electrical interface 21 can also be formed in such a way that a counter-contact element 20 having a correspondingly small diameter can be inserted into the interior of the contact sleeve 6 of the contact element 2 on the left in the figure. Or the left-hand contact element 2 is so large in diameter that it can be pushed over the right-hand contact element 2 like a sleeve for electrical contacting.
  • the contact sleeve 6 and / or the crimp sleeve 13 preferably consists of nickel-plated, silver-plated or gold-plated metal.
  • Points of contact which result in the assembled contact element 2 and mating contact element 20 at the contact points 17, create a very low-resistance electrical connection.
