  • the subject relates to a cable seal and a method for making a connection between a main cable and a branch cable in such a cable seal.
  • connection points between two electrical lines are usually implemented using a cable lug and/or appropriate screw connections. It is important here that the connection point is protected against the ingress of moisture.
  • this is usually implemented using a shrink tube with an inner adhesive, which is pulled over the connection point and then shrunk.
  • a heat-shrink tubing particularly in connection with silicone-coated cables, is problematic with regard to longitudinal water that creeps between the heat-shrink tubing and the cable insulation. A complete seal is hardly achievable here.
  • the so-called fording depth is also a relevant criterion, particularly for battery cables or other high-voltage applications in the automotive industry.
  • Vehicles can only be submerged in water to a certain depth. This depth is called the wading depth.
  • Laying battery cables under the floor leads to that the cables may be below the fording depth of the vehicle.
  • immersing underground electrical lines in water could permanently damage them.
  • Underfloor laying and/or laying outdoors is always a problem with regard to moisture penetration. Due to the electrification of the drive train, however, an underfloor installation and/or an installation in the outside area, in particular outside the passenger compartment, is increasingly being carried out.
  • connection between the cables must be specially secured against the ingress of moisture.
  • longitudinal water must be prevented from causing leakage currents or short circuits.
  • Shrink tubing is possible and the manufacturing effort for threading the cable into one is enormous.
  • the sealing effect particularly depending on the insulation material of the cable, is sometimes insufficient, especially in the case of silicone-coated cables.
  • the permissible ambient temperature for the use of such systems is also limited by the melting temperature of the inner adhesive.
  • a cable seal may also be referred to as a seal case, housing, enclosure or the like.

  • a connecting part connecting bolt, connecting piece, connecting lug, connecting part or the like is also meant.

It can be at any A center tap can be realized along the main cable and this can be sealed by the housing in question.
  • the advantage of the two-part housing is that after the main cable has been connected to the branch cable, this connection can be inserted into the lower/upper part, then the second part of the housing is placed and the housing closed in this way is sealed. Time-consuming threading of the connection into a Y-shrink tubing is no longer necessary.
