Definitions

  • the invention relates to a cable coupling for connecting two electrical lines of the same number of wires, which consists of a socket containing contact sockets and a plug having plugs with a precise fit, in which the connection points between the conductors of the wires and the contact sockets or plug pins each tight are surrounded by a solid protective body sprayed around the connection points from an insulating material that can be welded firmly to the sheath of the lines, in which the plug has an annular component for sealing in the area of the fit, and in which means to avoid unintentional separation of the plug and socket are provided.
  • a line coupling is apparent from US-PS-3 134 405.
  • a line coupling is known which is to be used for an underwater connection and must therefore be moisture-tight.
  • Both parts (socket, plug) of this cable coupling consist of several prefabricated elements that must be put together before a protective body can be pressed around the cable end.
  • the plug and socket each consist of a rubber insert for holding plug pins or contact sockets, a sealing ring to ensure the required pressure resistance, an aluminum sleeve surrounding these parts and the protective body pressed around the cable end.
  • a 0-ring and a sealing strip are also attached to the aluminum sleeve of the connector.
  • DE-OS-2 802 798 shows an electrical plug connection, the line-side end of which is to be protected against environmental influences by an externally applied shrink tube.
  • a line coupling as described at the beginning, is evident from US Pat. No. 3,124,405.
  • the socket of this line coupling has a collar-shaped extension and a radially projecting flange.
  • a circumferential recess is provided on the plug to accommodate the expansion of the socket.
  • the cable coupling is held together by a two-part shell to be applied from the outside, the two parts of the shell being held together by a spring ring.
  • This known line coupling is therefore complex and difficult to handle.
  • the connection of the two coupling parts themselves is moisture-tight due to the complex structure. However, if moisture penetrates the connection point due to gross damage, it can penetrate along the wires or conductors of the connected lines and lead to faults at the far end of the lines.
  • the invention has for its object to provide a line coupling for connecting two electrical lines, which is easy to manufacture and handle, which allows a simple and quick connection of the two coupling parts, which further ensures that no moisture can penetrate into the interior of the coupling and with which it is ensured in particular that moisture cannot reach contacts which are located at the free end of the lines without a special encapsulation being required for the line coupling.
  • the use of the O-ring on the extended socket of the connector creates a seal which ensures that the contacts of the socket and connector are protected against moisture, at least when the cable coupling is under normal load.
  • the effectiveness of the O-ring is significantly improved in that the lugs are attached to the plug, which engage in recesses in the socket and thus provide additional locking.
  • the special sealing with shrink sleeves and gluing is in principle only necessary for the coupling part, on the pipe of which a sensor to be protected against moisture is attached at the other end.
  • the other coupling part can be designed without a special seal.
  • both coupling parts can also be sealed in accordance with the invention.
  • both the socket and the plug are constructed to be fully sealed.
  • the sheath of line 1 surrounding the two wires is designated 6 and consists of a suitable insulating material, for example of polyvinyl chloride or of polyurethane.
  • a protective body 9 made of a suitable material is sprayed around the connection points between the conductors 7 and 8 of the two wires 2 and 3 and the contact sockets 4 and 5, this protective body also extending over the jacket 6 of the line 1.
  • the protective body 9 is provided with a cup-shaped extension 10, which serves to receive a plug.
  • This plug is shown, for example, in FIG. 2 and has a protective body 11, which also encloses the end of a two-wire line 12.
  • the two wires 13 and 14 of the line 12 are connected to connector pins 15 and 16, the protective body 11 also surrounding the connection points between the conductors 17 and 18 of the wires and the connector pins.
  • the protective body 11 is provided with a nozzle 19, which represents an extension of the protective body 11, and which fits exactly into the opening of the extension 10 of the can.
  • Two noses 21 and 22 are also attached to the socket 19 and engage in recesses 23 and 24 of the extension 10 when the plug is fully inserted into the socket.
  • the jacket 25 of the line 12 can consist of the same material as the jacket 6 of the line 1.
  • the protective bodies 9 and 11 are sprayed around the ends of the lines, an adhesion promoter is applied to the surfaces of the cores or the shrink tubes, through which a firm bond with the protective bodies 9 and 11 occurs during spraying. Furthermore, a material is used for the protective body, which can be firmly welded to the jackets 6 and 25 of the two lines 1 and 12. Accordingly, the protective bodies are preferably made of polyurethane.
  • the conductors 7 and 8 or 17 and 18 are designed as stranded conductors, they are compressed into their core after stripping and before the application of the shrink sleeves 26 and 27.
  • the conductor ends can be tinned, for example. The rest of the manufacture of the socket or plug is then the same as already described.
