Definitions

  • the invention relates to an electrical connection line for the electrically conductive connection of two contact points whose position is mutually variable, which consists of at least three insulated conductors having wires.
  • connecting lines are known as round cables and flat cables with any number of wires for years and used worldwide. They are manufactured in known technology in long lengths and usually initially wound on spools. For the electrical connection of two contact points connecting lines are separated in a distance of the contact points from each other corresponding length of the very long line and processed at their ends so that they can be electrically connected to the electrical contacts of the contact points. The number of wires that have the connecting lines, depends on the number of existing in the contact points electrical contacts. From the DE 19 62 536 C3 is also known as a helical electrical line known, which can then be used when one of the contact points to be connected is temporarily removed without interruption of the electrical connection over a greater distance from the other contact point. Such a connection line is used for example for connecting the handset to the base of a telephone.
  • the invention has for its object to make the initially described connection line so that they can follow wegqua limited changes in the relative position of two contact points without destruction.
  • connection line In this connection line, the wires have an odd course, so that they are longer in the stretched state than the idle state connection line.
  • the connection line for example, a non-destructive follow a limited increase in the distance between the two contact points. This also applies if one of the contact points is rotated relative to the other, with the connection line being twisted. In both cases, only a reversible stretching of the wires takes place.
  • Fig. 1 a schematic representation of two connected by an electrical connection line electrical contact points.
  • Fig. 2 . 3 and 4 three different embodiments of the connecting line according to the invention, also in a schematic representation.
  • a connecting line according to the invention can be used, for example, for use in motor vehicles. It may, for example, be mounted in a hollow steering column for connection of contact points on the steering wheel of a motor vehicle with contact points located at the other end of the steering column.
  • the connecting line can be used for example for the triggering mechanism of an airbag or as a connection to the elements of an electric power steering. It can also be used as a movable connecting line for electrically operable roof windows or sliding doors of motor vehicles. In all applications, the connecting line must be able to withstand a tensile load and / or a torsional load unscathed.
  • Fig. 1 two electrical contact points 1 and 2 are shown in the form of rectangular boxes, which are interconnected by an electrical connection line 3 are.
  • the contact point 1 should, for example, be stationary, while the contact point 2 should be displaceable relative to the contact point 1 in the illustrated embodiment. This is indicated by the double arrow 4.
  • the connecting line 3 should follow the movement of the contact point 2 non-destructive and without interruption of the electrical connection. This is achieved in that the wires are uneven and thus in the stretched state have a greater length than the connecting line 3 in total.
  • Such, extendable under tensile stress connection line 2 is for example in Fig. 2 shown. It has six wires 5, which are intertwined or linked and thereby connected in the course of the connecting line 3 movable. They are stretched at a tensile load and also at a torsional load of the connecting line 3, with a dependent on the particular structure of the connecting line extension of, for example, 3% to 20%. This change in length can follow the wires 5 nondestructive. The mesh of the connecting line 3 is thereby only slightly contracted. This movement is reversible, since the cores 5 go back to their starting position of the connecting line 3 corresponding initial position in case of elimination of the tensile or torsional load.
  • the same as shown in FIG Fig. 3 be equipped with a drawstring 6, by means of which they can be easily returned to their shorter rest position, when a leading to their extension train or Torsionsbelastung is repealed.
  • the tension band 6 may consist of a tensile but nevertheless stretchable material. However, it can also be spring-loaded at one end and guided over at least one deflection roller.
  • the wires 5 have a wave-shaped course. you are through Connected connecting elements 7, which are mounted at axial intervals and hold the wires 5 each movable.
  • the conductors of the wires 5 are advantageously designed as easily bendable stranded conductors, which consist of a large number of wires stranded or lumped together from electrically highly conductive material, in particular copper or aluminum or an aluminum alloy.
  • the insulation surrounding the conductors may advantageously consist of polyethylene.
  • the wires 5 are in the Fig. 2 and 3 shown bent to show their interconnectedness or easier to understand. In practical implementation, such kinks do not occur.
  • the connecting line 3 is shown as a flat, two-dimensional line. It can also be bent around its longitudinal axis when used, as a quasi-round structure can be used. It is also possible to produce the connecting line, for example, by braiding from the outset as a three-dimensional line.
