Definitions

  • the invention relates to a device for fastening and connecting a multi-core electrical cable to the motor of a pump, in particular a submersible pump with a tubular connection housing.
  • the object of the invention is to provide a fastening device of the type mentioned, which, with simple construction and assembly, has a high level of tightness against creeping longitudinal water and thereby allows loosening for multiple connections.
  • connection device or such a cable connector creates a releasable connection of the connection cable to the electric motor. Repeated connection is thus possible, so that the customer or user can use and connect different types of cables.
  • the detached cable ends are not changed when the cable is loosened, in particular during a repair, so that a new connection can be carried out easily.
  • the device has the same parts on both sides of the transverse wall, so that only a few parts can be produced.
  • connection device uses the same parts for connections with required explosion protection as well as without this requirement, so that no two different constructions are required.
  • connection housing represents the receiving body for the connector and simultaneously connects the motor housing and bearing bracket.
  • the dry motor interior In the case of submersible motors, the dry motor interior must be checked for leaks once the cable has been disconnected. When the cable is reconnected, leaks can occur which lead to leakage and destruction of the motor.
  • the interior of the engine In the type of construction according to the invention, the interior of the engine is not touched. It remains watertight, even if the engine were immersed in water without a cable. Checking the engine for leaks is called "pressing". This impression is a special step and is time-consuming. The engine is immersed in a filled water basin and pressurized with compressed air of approximately 1.5 bar on the inside. Then you observe those places that could be leaking. At these points, air comes out in the form of pearls that rise in the water. In the construction according to the invention, this test procedure is omitted if a cable was subsequently detached.
  • the cable entry is often potted with resin. It is therefore necessary to either carry out the potting again in a further connection or to use a so-called prefabricated cable, the end of which already carries the potting compound. In this case, it is a cable that the customer must obtain from the supplier. If the motors and pumps are explosion-proof, the customer cannot change the cables anyway, but must look at the explosion-protected components (it can be cast resin parts be). In the design according to the invention, the functions of longitudinal water tightness and explosion protection are separated from the cable and housed separately in the motor.
  • a particularly simple and tight construction against creeping longitudinal water and against pressurized water is given when the transverse wall is surrounded by a coaxial sleeve, into which the transverse wall is cast and which is fastened watertight to the inner wall of the connection housing.
  • the tightness is further improved if there is a sealing washer on one side of the transverse wall, which is penetrated by the pins.
  • a constructional simplicity and easy assembly is achieved if the bushings lie on both sides of the transverse wall in a two-part bearing part (plug-in part), which forms a guide channel for each bushing sleeve.
  • one half of the bearing part can be latched with a central, coaxial, projection-forming projection in a central opening of the other half.
  • the bearing part forms a plug-in part together with the inserted socket sleeves into which the cable wires (wires) lead on one side and which can be plugged onto the pins with its other end.
  • an identical plug-in part can be plugged onto the pins on both sides of the transverse wall.
  • an axially parallel or coaxial guide pin which protrudes on both sides, is cast in the transverse wall and lies in each case in a bore in the bearing part.
  • an easy-to-assemble construction with secure Hold is created when a threaded sleeve is screwed into the outside of the connection housing, which lies with its external thread in an internal thread of the connection housing, through which the connection cable including cable sheath is guided and which is closed on the outside by a ring nut.
  • wires or wires 24 of the connecting cable 25 or the wires / wires 26 of the motor connecting wires 27 are fastened in the sockets 18, so that the respective plug-in part 14 is fastened to the connecting cable 25 or to the motor connecting wires 27 on both sides of the transverse wall 10.
  • the connecting cable 25 is inserted on the side of the connecting device facing the motor through a threaded sleeve 29, which is screwed with its external thread into an internal thread 30 of the connection housing 5.
  • the threaded sleeve 29 consists of an elastomer and can be compressed all around in radial directions at the end facing away from the motor by means of an externally screwed-on ring nut 30. By screwing this ring nut 30, the outer jacket of the connecting cable 25 is tightened by the threaded sleeve 29.
