Definitions

  • the invention relates to an arrangement of the type described in the preamble of claim 1 and known from DE-A-10 40 100.
  • connection must have low electrical resistance and high tensile strength.
  • the cross sections of the ends of two conductors to be connected are graded in the axial direction so that there is a relatively long overlap area in which the conductor ends are pressed together by a plurality of ring elements in such a way that a connection is formed whose diameter is equal to the diameter of the connecting conductor ends.
  • the wire ends have to be cut to size.
  • the axial overlap length of the conductors to be connected must be long if sufficient tensile strength and a low contact resistance are to be achieved.
  • a connection between electrical conductors 2 is known, which are pressed with a tie rod 4 arranged coaxially to the hollow ends of the conductors by ring elements 5, which are arranged over depressions in the tie rod 4 are. Portions of the conductor 2 and the tie rod 4 are pressed together by deformation through the ring elements so that the current conduction of the conductor 2 separated by a gap takes place via the ring anchor.
  • the compression sleeves or rings can be pressed together to such an extent that a conductor-identical connection can be made.
  • the nesting of the conductor ends over the entire area of the connection point, where the compression sleeves or rings come to lie has considerable disadvantages.
  • the ends of the conductors have to be cut to length in the longitudinal direction over the entire area of the compression sleeves or rings.
  • the axial contact length of the conductors to be connected extends over a long range in order to produce the necessary mechanical strength and to achieve sufficient electrical contact by means of conductor ends lying one above the other mainly in the longitudinal direction.
  • the axial length of the conductor contact surface crucially determines the overall length and the required insulation effort for the completed cable connection, for example in the case of a cable sleeve.
  • FIG. 1 the connection point 3 of the ends of two Milliken conductors 1 and 2 is shown before the pressing.
  • a Milliken conductor is a conductor designed as a waveguide, which consists of stranded conductor elements and in the hollow channel of which a cooling or impregnating liquid flows.
  • the two wire ends are cut to match each other.
  • the cut surfaces can be designed obliquely as in FIG. 1, vertically or step-like.
  • the tie rod 4 is pushed into the hollow channels 6 of the conductors 1 and 2. 37, 8 and 9 are pushed onto the conductor ends, the middle ring element 8 coming to lie over the connection point 3. With this the conductor contact will be effected later. Instead of a single ring element 8, several shorter ones can also be used.
  • the outer ring elements 7 and 9 the positive mechanical connection of the tie rod 4 with the conductor ends 1 and 2 is achieved later.
  • the outer ring elements 7 and 9 are primarily designed to absorb mechanical forces, while the middle ring element 8 should advantageously consist of a material with good electrical conductivity.
  • the tie rod 4 is machined in the axial direction at its ends 10 so that it can enter into a positive connection with the pressed-on conductor ends. This can e.g. by roughening, creasing or the like.
  • the tie rod 4 has a smooth surface in its central part, so that the elastic expansion of the tie rod is not hindered when the ring elements are pressed. Its tensile strength must be so great that it can additionally absorb the axial contact pressure which arises when the middle ring element is pressed on.
  • the tie rod 4 is hollow with a passage 5. 1, the ring elements 7, 8, 9 are pressed radially inwards.
  • the anchor ends 10 are connected to the conductor ends 1 and 2 in a form-fitting manner by the surrounding ring elements 7 and 9. These ring elements are compressed up to the conductor diameter. In the area of the inner ring element 8, the conductor elements are radially compressed to such an extent that there is a material flow in the axial direction, whereby the conductor ends 1 and 2 are contacted with high pressure. The elastic expansion of the tie rod 4 supports the maintenance of the contact pressure.
  • the tie rod 4 has a flange 13 in its center, as a result of which the two conductor ends 11 and 12 are kept at a distance from one another.
  • the tie rod 4 ' is pressed tensile at its ends 10' with the conductor ends 11 and 12 by means of the end regions 7 'and 9' of the compression sleeve 15.
  • the conductive material 14 is pressed to produce a conductor contact.
  • the radial compression of the two conductors to be connected is somewhat less at this point than at the level of the anchor ends.
  • the electrical contact is made primarily via the axial extension of the conductive material 14.
  • the compression sleeve 15 is radially compressed to the extent that the diameter of the connection point is equal to the diameter of the conductor to be connected.
