Definitions

  • the invention is in the field of assembly technology for power cables and is to be used in the structural design of a compression sleeve with which the conductor of a medium or high voltage cable is connected in a prefabricated cable set.
  • the connection of the conductors is carried out with the aid of compression sleeves which are provided with a plug part.
  • the outer diameter of the individual compression sleeve is smaller than the outer diameter of the wire insulation (US-A-3 571 783).
  • this requires either a small conductor cross section or a large wall thickness of the insulation.
  • these diameter ratios do not exist, however, since compression sleeves made of copper or aluminum have to have a certain wall thickness in consideration of the required contact forces. This wall thickness is greater in aluminum compression sleeves because of the lower strength than copper than in copper compression sleeves.
  • the diameter ratios mentioned are particularly important for prefabricated sets, the insulating body of which is made of an elastic material and which have a bore for receiving the cable core, the diameter of this bore being smaller than the core diameter.
  • a compression sleeve made of aluminum is used for the conductor connection, which is welded to a contact part made of copper.
  • the contact part is provided with a thread for receiving a contact pin (US-A-3 876 280).
  • a compression sleeve For the connection of bare electrical conductors which are subject to relatively large tensile stresses, a compression sleeve is known per se, the actual pressing part of which is made of steel and which is used for electrical contacting of the conductors in the middle with a copper sleeve and for establishing a good mechanical connection on both sides with two clamping sleeves is lined (DE-B-1 072671). Furthermore, a press sleeve has already been proposed for switching wires, which is provided with a plug part and whose press part consists of an inner, soft copper sleeve and an outer steel sleeve (EP-A-18 863 according to Art. 54 (3), in relation to France) .
  • the invention has for its object to ensure by a structural design of the press sleeve that for cable sets with an elastic insulating body, even with large conductor cross-sections, the outer diameter of the press sleeve smaller than the outer diameter of the cable core is.
  • the press sleeve connected to the plug part consists of an inner partial sleeve made of copper or aluminum and an outer partial sleeve made of steel.
  • the outer diameter of the compression sleeve is smaller than the outer diameter of the wire insulation even with larger conductor cross sections.
  • the two partial sleeves of the two-layer press sleeve then take on the one hand essentially the mechanical function of the press sleeve, on the other hand essentially the electrical function.
  • the two-layer compression sleeve can be manufactured in two ways.
  • the individual layers can be produced as independent components and put on top of one another. But you can also use two-layer material, for example clad, rolled or welded strip material.
  • recesses can also be provided in the outer sleeve layer (pressure sleeve).
  • pressure sleeve When pressing the compression sleeve, the soft contacting material of the inner sleeve layer can then flow into the recesses of the outer sleeve layer under the pressure of the tool jaws and in this way still stiffen the entire compression sleeve.
  • Fig. 1 shows a press sleeve 11 which is provided with a plug part 10 made of copper.
  • the compression sleeve itself consists of an inner partial sleeve 12 made of aluminum and an outer partial sleeve 13 made of steel. Press sleeve 11 and plug part 10 are connected to one another by friction welding.
  • the two-layer press sleeve 11 is connected by cold pressure welding to a plug part 20 in the form of a socket.
  • the compression sleeve 11 also consists of an inner partial sleeve 12 made of aluminum and an outer partial sleeve 13 mounted thereon made of steel.
