  • the cables are already immovable at a distance of several tens of centimeters from the connection or connection, for example, when the cables are buried in the ground and only one socket hole is exposed for installation of the connection or the connection or if, for example, the outer insulation or reinforcement of a multiphase cable must be discontinued, if the individual cable wires are to be connected to the same or other wires.
  • the cable core can only be bent laterally when installing connection, branch or connection elements.
  • connecting elements are clamped transversely to the cable axis.
  • the connecting elements are mounted at the ends of the cable ladder to be connected, for example by means of sleeve-shaped screw connectors which receive the cable ladder and are permanently clamped to the sleeves by pressure screws arranged transversely to the longitudinal axis.
  • the pre-assembled on the conductors fasteners are interconnected.
  • the cable cores should be bent out as little as possible in order to prevent unintentional loosening of the conductor connections.
  • From the GB 2 319 402 A is a two-piece connector for conductors known. Due to the contact elements of the two connecting elements predetermined contact surfaces, the cables to be joined together when connecting the two connecting elements must be more or less rotated in order to achieve a surface contact of the contact elements of the connecting elements. There is a risk that the connection between the connecting element to be rotated and the conductor mounted thereon loosens again due to the mechanical stress associated with the rotation. This is increasingly true in cramped space and low free cable lengths.
