Definitions

  • the present invention relates to a coupling sleeve (coupling, connecting element) for connecting conductors, in particular heating conductors or SerienMapleitern. Furthermore, the present invention relates to a supply box for feeding a heat conductor.
  • heating conductors In plant construction or in process engineering, it may be necessary to heat fittings and pipelines with electrical heating conductors in order to guarantee their functionality even at low outside temperatures or to increase the viscosity of the liquids flowing through them.
  • Such heating conductors have in the middle a so-called hot part, which can be connected to so-called cold cables on both sides, since the hot part can not be connected directly to an electrical connection box or supply box due to its high operating temperature.
  • Such a heating cable is shown in Fig. 2.
  • the temperature-determining actual hot part of the heating cable is a strand 214, which is heated by its electrical resistance when exposed to a corresponding current.
  • the strand 214 is surrounded by a first insulating layer 215 made of plastic, for example PTFE.
  • the first or inner insulating layer 215 is enclosed by a glass fiber-reinforced glass ceramic strip 216, over which a protective earth braid 212 is wound, which protects the heating conductor against short-circuit or ground fault in the event of mechanical damage.
  • the entire heating conductor is again surrounded by an outermost protective cover (conductor jacket) 217 made of plastic, such as PTFE, which represents a stable mechanical and electrical-insulating protection up to 260 ° C.
  • both the hot part and the cold part of Serienfilleitern have such a structure.
  • both the strand 214 and the Erdschutzgeflecht 212 as shown in FIG. 3 is separated from the insulation.

  • connection point is then wrapped with insulating tapes, or provided in the more complex case with a union fitting, which is poured in the interior at the junction with silicone compound.
  • the purpose of these measures is to mechanically relieve the electrical connection point, if tensile forces occur along the heating conductor.
  • the silicone potting also serves to seal the electrical connection moisture or waterproof against the outside, in particular to avoid a short circuit between the heating wire and grounding braid.
  • European Patent Application EP 1 313 351 A1 discloses a connecting sleeve for heating conductors, in which the electrical connector is relieved of strain against an axial force effect.
  • This sleeve has two axially into each other screw-on base hollow body made of steel, through which one of the two conductors is guided and in which an electrical connector is received in the screwed-together state.
