Definitions

  • the invention relates to a cable connector according to the preamble of claim 1.
  • this is an angular plug-in closure for plugged-in conductor connections for a transformer or switchgear connection in medium-voltage networks, by means of which a medium-voltage cable is connected to a device with a bushing, as described, for example, in DEZ Elektrizmaschines ocean 1985, 2 ; 55-58.
  • a base piece 20 made of copper is attached to a welding flange 9 of a connecting device 8 made of aluminum by means of friction welding.
  • the connecting device 8 is designed as a compression sleeve, which makes a contact with a cable conductor 3 of a cable 1, which is inserted with an insulating sleeve 2 into a connector housing 10.
  • the base piece 20 is in a corresponding recess of a lining 12 made of semiconducting material, which is surrounded by insulating material 11 to form the connector housing 10.
  • the base piece 20 has a threaded bore into which a plug contact pin 30 is screwed with its threaded end 31.
  • An external hexagon is provided on the plug contact pin 30 for tightening the screw connection.
  • a capacitive measuring point 14 is attached to the upper end of the connector housing 10.
  • the plug designed in this way (as shown in FIG. 10) can be plugged onto a device connection part 4 in such a way that a conical insulating body 5 of the device connection part 4 sits tightly in the correspondingly conical end of the plug housing 10.
  • the plug contact pin 30 is in this case in a contact sleeve 7 which is attached in a copper connecting bolt 6.
  • the connecting device 8 is plugged onto the cable conductor 3 and pressed by means of a pressing tool. Then the cable 1 (with the grommet 2 pushed over) together with the base piece 20 is inserted into the connector housing 10 until the base piece 20 is seated in the corresponding recess in the connector housing 10. The plug contact pin 30 is then screwed into the base piece 20 with its threaded end 31.
  • This known cable connector has a relatively long length l .
  • the assembly is relatively complex, in particular with regard to the pressing of the connecting device 8.
  • the known cable connector also includes a large number of parts which are to be electrically connected to one another so that a plurality of contact resistances add up.
  • the invention has for its object to develop a cable connector of the type mentioned in that the size can be reduced at the same time with little construction.
  • an already necessary part namely the plug contact pin
  • the plug housing can be constructed very simply, since the plug contact pin must be accessible from the outside anyway and can therefore be screwed in with a tool.
  • the plug contact pin preferably has a tool attachment piece at its end opposite the thread end.
  • This in turn is advantageously connected to the plug contact pin via a predetermined breaking point, this predetermined breaking point being designed such that the tool attachment piece breaks off at a defined torque. This ensures that no errors can be made during assembly and the contact resistances between the cable conductor and the plug contact pin or the contact forces are clearly defined.
  • the contact resistance between the cable conductor and the plug contact pin is minimized compared to the previously known cable plugs, since an optimal connection between the cable conductor and the end of the plug contact pin acting as a clamping screw is established.
  • this is deformed by the preferably spherical end of the plug contact pin by its rotational movement and simultaneous pressing movement, so that a full-surface and positive contact between the cable conductor and the plug contact pin or its end is produced.
  • the contact pressure between the plug contact pin and the cable conductor can be adjusted particularly precisely if you lubricate the threaded section with a lubricant before screwing it in.
  • the base piece preferably has a cylindrical outer contour, so that it is very easy to manufacture.
  • the axis of symmetry of the base piece is perpendicular to that of the plug contact pin.
  • the connector housing can be designed in such a way that during assembly the base piece is first plugged onto the cable conductor and this arrangement is then inserted into the housing before the connector pin is screwed in.
  • the base piece can also be formed with its axis of symmetry concentric with that of the plug contact pin, in which case it is then preferably cast into the plug housing.
  • the receiving bore in the base piece is preferably designed as a blind hole, so that a defined insertion depth of the Cable conductor is guaranteed and no tips protrude from the base piece, which could cause field concentrations.
  • the base piece is inserted into the connector housing during assembly, it is generally ensured that no deep scratches can occur in the semiconductor material inside the connector housing, since the base piece itself is formed with chamfered edges or roundings to avoid field concentrations. If the base piece is also cast into the plug housing, the receiving bore has a relatively strong chamfer at its inlet opening to form an insertion section for the cable conductor. In this case, it is also possible to provide a separate cap made of very thin aluminum, which is placed on the cable conductor and then pushed into the base piece. It is important to ensure that the location hole is deep enough and that the cap is flat enough to allow the plug contact pin to have direct access to the cable conductor.
  • an adjustment surface is advantageously formed on the base piece and a corresponding surface in the plug housing, so that when the base piece is inserted into the plug housing, the threaded bore for receiving the plug contact pin has the correct direction.
  • a screw / plug contact pin is provided with respect to the plug contact pin and is designed to connect further plugs (via outer cone spacers) or an end cap in a manner known per se, so that a T plug is produced.
  • the plug contact pin can also be provided with a thread, so that a T plug with (conditionally detachable) screw contact is created as it is used for higher currents.
  • the cable connector according to FIG. 1 differs from the known cable connector according to FIG. 10 explained at the outset essentially in that the connecting device 8 with its welding flange 9 is not used.
  • the base piece 20 is essentially cylindrical and, as shown in FIGS. 4 and 5, has a receiving bore 21 which is closed off by an end face 24, that is to say forms a blind hole.
  • a threaded bore 23 is provided in the base piece 20 transversely to the receiving bore 21, the central axis of which intersects the central axis of the receiving bore 21 at a right angle.
  • the base piece 20 is seated in a liner 12 made of semiconducting material, this liner 12 tapering in the insertion direction of the cable 1 and forming a recess 15 which receives the base piece 20.
  • a plug contact pin 30 with its threaded end 31 can be screwed into the threaded bore 23.
  • the thread end 31 is closed by a spherical end face 32.
  • the plug contact pin 30 merges via a cone 36 and a predetermined breaking point 35, which is designed as a circumferential notch, into a tool attachment piece which, in this embodiment, is designed with an internal hexagon 34 in which a hexagon key for screwing in the plug contact pin 30 in the threaded bore 23 can be inserted.
  • a tool attachment piece 33 can also be designed similar to a hexagon nut.
  • the base piece 20 has chamfered outer edges and a chamfer 22 at the entrance of the receiving bore 21, so that a funnel-shaped inlet for inserting a cable conductor 3 is formed, as shown in FIGS. 4 and 5.
  • an adjustment surface 25 designed as a flattened portion is provided in the cylindrical outer surface, as is shown in FIGS. 6 and 7.
  • This adjustment surface 25 corresponds to an adjustment counter surface in the connector housing, so that when the base piece 20 is inserted into the connector housing 10, a precisely defined position of the base piece 20 is achieved.
  • the procedure is to first peel off the insulation at the end of the cable 1 or to set it down until a sufficiently long piece of the cable conductor 3 is exposed.
  • a base piece 20 is then placed on the cable conductor 3 and inserted together with the latter into the cable connector 10.
  • a plug contact pin 30 is screwed into the threaded bore 23 with its threaded end 31.
  • the spherical end face 32 of the plug contact pin 30 compresses the cable conductor 3 and deforms its material, so that a flat, positive transition between the cable conductor 3 and the end face 32 of the plug contact pin 30 is created.
  • the screwing process is completed when the tool attachment piece 33 breaks off at the predetermined breaking point 35. This is dimensioned so that a sufficiently large torque can arise to create a perfect electrical connection.
  • FIG. 8 differs from that according to FIG. 1 in that in order to create a T-plug, projecting in one piece from the base piece 20 a screw plug contact pin 40 is provided coaxially with the plug contact pin 30.
  • a screw plug contact pin 40 is provided coaxially with the plug contact pin 30.
  • the plug contact pin 30, which is smooth in the embodiment according to FIGS. 1 and 8, is provided with a thread, so that a conditionally detachable T plug is produced.
  • the base piece 20 is screwed with the screw plug contact pin 40 with the interposition of a shim 26 into a device connection part 4 or into its threaded hole in the connecting bolt 6 until it is stuck.
  • the connector housing 10 is placed so that the base piece 20 is in the position shown in FIG. 9.
  • the base piece 20 is also cylindrical, but the cylinder axis is aligned with the axes of the plug 30 and the screw-plug contact pin 40.
  • the cable 1 with its exposed cable conductor 3 is inserted into the connector housing 10 until the cable conductor 3 is seated in the receiving bore in the base piece 20.
  • the plug contact pin 30 is screwed in using a tool which is attached to an external hexagon 37 on the plug contact pin 30 until the cable conductor 3 is clamped.
  • a tool attachment piece 33 according to FIG. 2 it is also possible here to provide a tool attachment piece 33 according to FIG. 2 on the plug contact pin 30.
  • cables with cable conductors of different cross sections can also be used together with a base piece 20 with a (single) specific cross section of the receiving bore 21.
