Definitions

  • the invention is in the field of fittings for electrical cables and is to be used in the structural design of a single-pole connector which is arranged at the end of a single-core, shielded cable and has an insulating body made of an elastomeric material which is sealed off from the cable end.
  • connection lines of the lighting devices are looped.
  • the connection of the connection lines with the cables can be made via a single-pole connector.
  • both the ends of the connecting lines and the ends of the cables are provided with corresponding plug connectors, in which the plug connector part (plug or socket) to be connected to the respective cable end is surrounded by an insulating body made of natural or synthetic rubber.
  • the insulating body surrounds the stepped cable end in the form of a hollow cylindrical body which is open towards the cable and has noses on its inside, and the space between the insulating body forming a mold and the end of the body is covered with a casting resin filled, the cable shield is led out of the opening of the insulating body.
  • a connector can be produced easily and efficiently and is characterized by a moisture-proof and mechanically heavy-duty connection of the insulating body to the cable end.
  • the cast resin body is the moisture-protecting link between the insulating body and the cable jacket and the cable insulation (DE-A-26 25 893).
  • prefabricated insulating bodies which consist of an elastomeric material and can be pushed onto the appropriately prepared cable end with elastic expansion (DE-A-1148613).
  • sets which consist of heat-shrinkable plastic bodies. These include, for example, udder-shaped parts for division end closures (EP-A-0 039 601) or also two-layer cylindrical parts, one layer of which is only subjected to elastic stress (DE-A-30 12 971, FIG. 7 A).
  • the invention is based on the task of omitting the cast resin body and by exclusively using prefabricated parts and elements, the assembly of the connector on To further simplify the cable end and to ensure the applicability of the connector for cables with different plastic sheaths (polyvinyl chloride, polyethylene, natural or synthetic rubber).
  • the shield wires of the cable inside the insulating body are folded back onto the stepped cable jacket and surrounded with a sealing sleeve, that the insulating body with its entire inner surface with the interposition of a thin sliding and sealing layer on the stepped cable end rests elastically that at the transition from the insulating body to the cable an elastic cap is provided which rests on the one hand in an elastically sealing manner on the insulating body and on the other hand rests on the cable sheath and the connecting line in an elastically sealing manner with two finger-like approaches, and that the cable and the connecting line are in the region of the finger-like Approaches are surrounded by a hose clamp.
  • the exclusive use of elastic parts which rest on the cable end and the connecting line with elastic expansion, ensures the required tightness of the connector against moisture.
  • the corresponding sealing surfaces of the insulating body and the cap can be coated with an adhesive or a gel-like sealing compound. This is particularly appropriate if heat-shrinkable bodies are used entirely or partially as elastic parts.
  • the hose clamp provided according to the invention which surrounds the connecting line and the cable directly or indirectly with the interposition of the finger-like approaches of the elastic cap, ensures mechanical protection of the cap against stresses that may result from the further handling and assembly of the connecting line.
  • FIG. 1 An embodiment of the new connector is shown in Fig. 1.
  • Fig. 2 shows an alternative embodiment for the insulating body.
  • Fig. 1 shows an end formed as a plug of a single-core, shielded power cable 1, the conductor, not shown, is surrounded by the insulation 11, to which the coaxial shield 12 made of wires and the plastic jacket 13 are applied.
  • the cable end designed as a plug initially contains the plug part 2, which is pressed onto the conductor of the cable or soldered to it.
  • the plug part 2 is pushed on by a slight elastic expansion Surround insulating body 3, which rests elastically on the insulation 11 and the jacket 12 of the appropriately prepared cable end.
  • the shield wires 12 of the cable 1 are first folded backwards onto the cable sheath 13 in order to ensure a uniform distribution of the shield wires on the cable sheath in the region of the insulating body 3.
  • the folded area of the shield wires 12 is provided with a sealing sleeve 14, which ensures a seal between the rear end of the insulating body and the cable jacket.
  • this sealing sleeve can be a pasty sealing compound, for example silicone grease.
  • it can also be an elastic bandage, which is optionally pushed onto the shield wires with additional use of an adhesive or a sealant with elastic expansion, for example a sleeve made of a polyolefin body, a silicone rubber body or an elastomer part.
  • a heat-shrinkable part can also be considered.
  • the elastic cap 4 On the cable end of the insulating body 3, the elastic cap 4 is further applied, which has two finger-like approaches 5 and 6 for the passage of the cable 1 and the connecting line 9, the conductor of which is connected via a press connector 8 to the shielded wires 12 which are combined into a braid.
  • the elastic cap which can also consist of an elastic polyolefin material, silicone rubber or an elastomer, is fixed on the insulating body by means of a hose clamp 10, which rests on the shoulder 17 of the insulating body. Furthermore, the shield-side end of the connecting line 9 is fixed relative to the cable 1 with the aid of the hose clamp 7 in order to rule out mechanical stress on the finger-like attachment 5 at the transition to the cap 4 or the finger-like attachment 6.
  • a heat-shrinkable part can also be used for the elastic cap 4. If the cap is coated on the inside with a hot-melt adhesive, the use of the hose clamp 10 may be dispensed with in this case.
  • Fig. 2 shows an embodiment for the insulating body, in which the cap is designed as a heat-shrinkable part and integrated into the insulating body.
  • the insulating body is divided into the elastic region 3 ', which lies essentially on the connector 2 and the cable insulation 11, and the heat-shrinkable region 4' with the finger-like projections 5 'and 6', which are assigned to the cable jacket 13 and the connecting line 9 are. So this is a mixed elastic / heat shrinkable part. In this case, it is advisable to provide the inner surfaces of the shrinkable area with a hot-melt adhesive 15.
