Definitions

  • the present invention relates to a high current cable connector particularly suitable for use in harsh environments in which the cable connector is subjected to mechanical stresses such as vibrations, heat and the like.
  • the cable connector according to the invention is used in wind turbines, but also the use in shipbuilding and in particular in naval shipbuilding is advantageous.
  • High current is also referred to as high current in some branches of industry, with the following terms being synonymous with each other.
  • High current here refers to currents as defined in the corresponding DIN standards, for example for the measurement of high currents, the high current usually has a current strength of more than 100 A.
  • connection system has become known, which is designed in particular for use in a wind turbine.
  • the connection system has two connecting pieces, which engage behind each other for securing with regard to tensile loads. In a tensile load of the connection system in the cable longitudinal direction so changes the electrically effective contact surface of the connection system.
  • the invention has for its object to provide an improved cable connector for high current available, which can be used to the disadvantages of the known in a mechanically demanding environment.
  • the cable connector according to the invention is provided as a connector for high-current cables.
  • the cable connector has a first and a second connector, each having a contact socket for connection to the cable. Furthermore, fastening means for releasably connecting the connecting pieces to each other are provided.
  • each of the connecting pieces is provided with an electrical contact surface.
  • the electrical contact surfaces each extend in a longitudinal direction and rise toward a free end of the connector in the manner of a ramp such that the connecting pieces transmit a force to the ramp-shaped contact surface of the other connector in a mechanical tensile load along the longitudinal direction.
  • the inclination of the contact surfaces is such that when the cable connectors are pulled apart in the longitudinal direction, the contact surfaces are pressed flat against one another.
  • the contact surface By pressing the contact surfaces on each other, the contact surface always develops the same under tension and does not change.
  • Another particular advantage of the sloped contact surfaces is that the fasteners that extend across the cable connector are not loaded with tension. The engaging tensile forces are each received by the other connector, so that shear forces on the guided transversely through the cable connector fastener can be avoided.
  • the connecting pieces in their connected form form a cylindrical connecting body which is held together by a pair of fastening means extending through the connecting body.
  • a pair of fastening means extending through the connecting body.
  • the connecting pieces are designed as identical parts.
  • the use of common parts for cable connectors has great advantages, especially in the manufacture and assembly of the cable connector.
  • mating connectors are not matching or even pre-assembled on the tower sections.
  • the production costs and the costs for storage are thereby significantly reduced.
  • the contact surfaces each extend over the preferably entire width of the connecting pieces and are formed as a surface. In the connected state of the connectors, the surfaces are flat over their width to each other and are secured by the connecting means to each other. By extending the contact surface over the entire width of the connector, the connectors can be easily merged even from very different positions and orientations.
  • each of the contact surfaces has a continuous, mutually parallel teeth whose orientation is equal to the connecting pieces and runs such that the teeth of the Contact surfaces of two interconnected connectors at an angle superimposed electrical contact points of the toothing create.
  • the use of a toothing is based on the idea to create a defined contact surface by the juxtaposition of two teeth, having defined contact points, in which an electrically conductive contact occurs.
  • the orientation of the toothings at an angle ensures that the effective contact surface has punctiform contact surfaces, in each of which higher parts of the teeth, for example a tooth tip or a dental plateau, lie on top of one another. Even with a tensile load or vibration of the interconnected connectors does not change the effective contact surface, there is always tooth on tooth in the contact surface and forms the electrically conductive contact surface.
  • the contacts are divided in half into two sections, of which a first section has a toothing with a first orientation and the second section has a second, perpendicular to the first orientation toothing. If the connecting pieces are superimposed and connected to each other, the first portion of the one connecting piece comes to lie on the second portion of the other connecting piece and vice versa, so that the orientations are perpendicular to each other. In this configuration, it is possible, for example, to orient the toothing in one section in the longitudinal direction of the connecting piece, while it is oriented in the other section in the transverse direction. But also oblique orientations are possible.
  • each of the contact surfaces is provided with a uniformly continuous toothing, which has an oblique angle, in particular a 45 ° angle to a longitudinal axis of the associated connecting piece.
  • the two oblique angles then have a different orientation, which ensures that tooth comes to rest on tooth with a defined contact surface. If a 45 ° angle relative to the longitudinal direction is selected for the oblique angle, the serrations enclose a 90 ° angle with one another.
  • the fastening means comprise two screws arranged one behind the other in the longitudinal direction, one of which is arranged captively in one of the connecting pieces. Even with the captive in the connector arranged screw pair, the connectors remain the same parts. When establishing the connection, the one screw is guided from one side through the connecting pieces, while the other screw is guided from the other side through the connecting pieces.
  • the use of a captive arranged in the connector screw has great advantages for the assembly, since the fitter has to handle only a few parts.
  • lost fasteners such as nuts and bolts pose a great risk of injury in the construction of the tower, as they fall from a great height and can continue to hurt working people. This is also avoided by the captive fastening means.
  • the fastening means on a pair of nuts with an additional external thread which are each screwed into one of the connecting pieces.
  • External thread and internal thread of In this case, mothers have an opposite orientation, so that when the screw is screwed into the internal thread, the nut already screwed in the connecting piece does not unscrew and is therefore designed to be captive.
  • the connecting piece has a first end face on its side facing the contact neck, standing transversely to the central longitudinal axis of the connecting piece.
  • the central longitudinal axis of the connector is not in the contact surface, but includes an inclination angle of the contact surface with this.
  • the pointing to the contact piece end face may be perpendicular or inclined to the central longitudinal axis of the connecting piece, wherein the end face is pulled on a tensile load of a corresponding end face of the other connector away.
  • the connector also has at its free end a transverse to the central longitudinal axis of the second end face, wherein in the connected state of the formed as equal parts connecting pieces, the first and second end faces of the connecting pieces are arranged opposite to each other and parallel to each other.
  • the contact piece has a conical transition section, which has a smaller diameter on its side facing the end face than on its side facing the contact surface.
  • the conical transition section directs as a truncated cone of the diameter of the contact piece, whose end face can be connected to a cable to a larger diameter of the Connecting body over.
  • the continuous transition has the advantage that an electrical insulation of the cable connector can be easily mounted and also the electrical resistance of the cable connector does not change abruptly along the connection of the end face to the contact surface within the connecting body.
  • each of the connecting pieces has an orientation mark indicating an intended fixing position. Due to the intended mounting position, the contact surfaces receive a desired orientation and the connecting means are also connected to each other in a desired direction.
  • an aluminum alloy is particularly preferred as the material.
  • the common disadvantages of aluminum alloys for connectors is that the aluminum tends to flow under heat and vibration. As a result, for example, the contact surfaces or the current-conducting cross section can change significantly. In the cable connector according to the invention such a flow movement is excluded both by the design of the contact surfaces and by the connection with the contact socket and it remains a consistently good electrical contact.
  • the contact surfaces and their teeth are provided with a metallic coating.
  • Aluminum alloys can tend to oxidize, so that a consistently good electrical contact is ensured by a metallic coating, for example with tin, copper or silver.
  • tooth spacings of 300 ⁇ m to 600 ⁇ m have proven to be preferable for the teeth.
  • flat teeth are used with a plateau, wherein the plateau then has a width of 50 microns to 150 microns to form the desired electrical contact surface.
  • a cable connector system which is very suitable with regard to installation has a cable connector according to the invention, of which a pair of connecting pieces are each connected at the end to a line section which can be fastened in a tower section.
  • the line section with its connecting pieces can be preassembled, so that when the tower is erected, only the cable connectors must be connected to one another.
  • a preferred cable connector system additionally has an insulation sheath that electrically isolates the connected cable connector from the outside.
  • the Insolationshülle is designed as a tube and in particular as a shrink tube.
  • the shrink tube is mounted on the interconnected connectors and shrunk onto the finished connected connectors. The shrinking process can be done warm or cold.
  • the cable can be well connected to the contact studs via resistance butt welding. This connection is mechanically strong and produces a uniform electrical contact between cable and contact piece.
  • the cable also has a longitudinally extending marking which is aligned with the orientation mark of the connecting pieces. As a result, the orientation mark on the connectors with the aid of Marking on the cable clearly visible and recognizable during assembly from a distance.
