Definitions

  • the invention relates to an arrangement for contacting an electrical conductor, which consists of a plurality of stranded, aluminum-containing wires, by means of a contact element having parts for mechanically fixed around it and pressing with the conductor, in particular in a crimped connection (US Pat. DE 198 21 630 C1 ).
  • the aluminum-containing wires used therein are either made entirely of aluminum or are copper-clad aluminum wires known as copper-clad aluminum wires.
  • a significant advantage of such electrical conductors, which consist of a larger number of such stranded wires than stranded conductors, is less weight compared to copper.
  • the conductor is constructed as a stranded conductor made of copper-clad aluminum wires.
  • the fixed by crimping on the conductor contact element has, relative to the enclosed conductor, either in the axial direction extending slots or it is wavy. Thermal expansion stresses occurring during extreme temperature fluctuations are thereby to be compensated elastically.
  • the invention has for its object to make the initially described arrangement so that the electrical contact between the contact element and conductor with great certainty is maintained over time.
  • the at least one located within the same pressure body, which presses through its resilient, provided with a restoring force part (at least one), the wires of the conductor constantly against the contact element, because when attaching the contact element is compressed from its rest position and will permanently spring back into it due to its restoring force. That's enough with appropriate Dimensioning of the pressure hull and in particular its resilient part to - as already mentioned - to press the wires of the conductor constantly against the contact element.
  • the pressure body can be mounted continuously along the entire length of the conductor within it. In a preferred embodiment, however, the pressure body is introduced only before the assembly of the contact element in the conductor of the end-face end so that it is present in the area which is enclosed by the contact element after its assembly.
  • a stranded conductor consisting of stranded aluminum wires is described below, representative of a stranded conductor consisting of copper-plated wires. For the sake of simplicity, he is referred to as a "leader".
  • a liberated from its insulation 2 conductor 1 which consists of a plurality of stranded wires 5 (Fig. 5 and 6) made of aluminum.
  • a preferably made of copper contact element 3 is to be placed, which is indicated schematically in Fig. 1.
  • a pressure body 4 is mounted centrally in a preferred embodiment, which is shown in Fig. 2 in its rest position.
  • the pressure body 4 has at least one resilient, a restoring force exhibiting part.
  • ladder 1 should at least one Pressure element 4 may be present. This embodiment will be considered below. But it can also be used two or more pressure hull.
  • the contact element 3 is pressed around the conductor 1, preferably in a crimped connection, as shown in FIG. In this case, not only the diameter of the conductor 1 is reduced, but also the pressure body or its resilient part is compressed to smaller radial dimensions. This is evident for example from FIG. 4.
  • the pressure body 4 may be present over the entire length of the conductor 1. It is then introduced continuously in the manufacture of the conductor 1 in the same, advantageously centrally between the wires 5 of the conductor 1.
  • a pressure body 4 can be carried out as shown in FIG. 5 and 6 with advantage as an open tube 6 made of spring steel, whose longitudinal direction extending edges in the radial direction are offset from each other (Fig. 5), so that there is a kind of overlap of the edges.
  • radial pressure on the tube 5 the diameter thereof is reduced, wherein the same is compressed in the form of a spiral, as shown schematically in Fig. 6.
  • the tube 5 itself is at the same time "resilient part" of the pressure hull 4.
  • the tube 5 may have in more or less large axial distances extending in the radial direction slots.
  • the variant of the arrangement according to the invention with continuously present in the conductor pressure body 4 has the advantage that the conductor 1 can be cut at any point to define a contact element 3.
  • the pressure body 4 course also have a different, meaningful structure.
  • the pressure body 4 is mounted only in the region of the conductor 1, which is enclosed by the mounted contact element 3.
  • a correspondingly long, pin-shaped pressure body 7 can be introduced from the front end of the stripped conductor 1 between its wires 5.
  • Such a pressure body 7 is shown for example in FIG. 7.
  • the pressure body 7 may be equipped with at least one leaf spring 8 made of spring steel as shown in FIG. 7, here the resilient element of the Represents pressure hull 4.
  • the leaf spring 8 is mounted in the pin so that it can be pressed into the profile. According to FIG. 7, two leaf springs mounted on opposite sides of the pin are provided. But there may also be three or more, circumferentially staggered leaf springs 8 present on a pin.
  • an insulated conductor 1 is freed from its insulation 2 in a predetermined length. Thereafter, a pin-shaped pressure body 7 is pushed in the axial direction of the conductor 1 of its front side between the wires 5 of the same, with advantage as centrally as possible. Subsequently, the contact part 3 is pressed around the conductor 1, preferably with a crimping tool. By the pressing operation, not only the wires 5 of the conductor are pressed together, but also the resilient part of the pressure body 7. If the same according to Fig.
  • a leaf spring 8 made of spring steel (or more than a leaf spring), then the same is pressed into the pressure body 7 , It then presses due to their restoring force permanently against the surrounding the pressure body 7 wires 5 of the conductor 1, which are thus pressed continuously against the contact element 3.
  • a possible reduction in the dimensions of the wires 5 - due to flow of aluminum or temperature influences - can therefore not affect the electrically conductive contact between conductor 1 and contact element 3.
