Definitions

  • the present invention relates to a wiring harness for an electrical arrangement, in particular for a motor vehicle. Furthermore, the invention relates to an electrical arrangement that has the cable harness.
  • a chamber such as a machine chamber
  • a machine element for example a shaft, etc. extending from an inside of the chamber to an outside.
  • a rotor shaft extends from a stator chamber into the outside area of the stator chamber, for example into a brush chamber of the electrical machine, the stator chamber and the brush chamber being fluidically sealed from one another along the rotor shaft. This is necessary in particular when a cooling liquid is arranged in the stator chamber, which means that an electrical machine designed in this way is then a so-called wet-running machine.
  • a radial shaft seal is used along the rotor shaft on a wall element of the stator chamber through which the rotor shaft extends to prevent cooling liquid from escaping from the stator chamber in an undesired manner, for example from entering the brush chamber.
  • this radial shaft seal it is necessary in the corresponding Chamber, that is, for example, in the stator chamber, not to cause overpressure or negative pressure in relation to the outside area (for example, in relation to the brush chamber), which acts axially, that is, along the rotor shaft, in a disadvantageous manner on the radial shaft seal.
  • a motor vehicle is equipped with such a conventional drive unit or with such a conventional electrical arrangement or machine, it can happen, for example, that air in the chamber is heated or cooled, for example due to waste heat or due to the operation of the electrical machine an external cooling of the electrical machine, for example by fording. According to thermodynamic laws, this results in a pressure change in the chamber and consequently a pressure difference between the chamber and the associated outside area. For example, there is a pressure difference between the stator chamber and the brush chamber. This is accompanied by an undesirable axial load on the radial shaft seal and ultimately a reduced or less reliable sealing effect for the shaft seat of the chamber.
  • DE 10 2013 200 894 A1 discloses a generator housing which has a plug socket and a pressure equalization channel.
  • the pressure equalization duct connects an interior of the generator to the outside with a cable harness which is plugged into the connector base and which also serves to equalize pressure.
  • combining the plug base with the pressure equalization channel is particularly complex and a sealing effect depends on a plug element being correctly seated in the plug base.
  • such a generator housing with the connector base and the wiring harness for a series vehicle are unfavorable to handle, expensive and require a lot of space outside the generator, which aggravates a ubiquitous packaging problem in vehicle construction.
  • DE 10 2017 128 532 B4 discloses a cable with an electrical conductor which is integrated into an insulating material of the cable and surrounded by an electrically insulating and vapour-tight outer sheath of the cable.
  • a semi-permeable membrane which is permeable to air and water vapor, is arranged at one point on the cable, with the outer jacket having recesses in the area of the membrane, so that ventilation of the cable via the membrane is ensured.
  • such a conventional cable is particularly expensive in terms of production, operation and handling, since the semi-permeable membrane can be easily damaged, so that Liquid can come into direct electrical contact with the electrical conductor through the defective/damaged membrane. This would result in a short circuit.
  • a cable harness for an electrical arrangement is proposed.
  • the cable harness is designed to transmit electrical power between two electrical contact points that are arranged separately from one another.

  • the soul of the respective individual conductor can consist of a variety of be formed electrically conductive wires or have exactly one electrically conductive wire.

  • the ferrule can have a cable lug that is electrically conductively contacted with the core.
  • the respective connection end is an end area of the cable harness, at which the cable harness ends along the direction of longitudinal extension.
  • the cable harness has at least two electrical connection elements for each individual conductor, with a respective one of the connection elements being arranged on a respective one of the connection ends.
  • the cable harness can also have multiple strand guests, so that the cable harness has three, four, five, etc. connection ends.
  • the cable harness also has a hollow channel element, which is formed separately from the (respective) individual conductor and runs along the longitudinal extension direction, approximately parallel to the individual conductor or to the individual conductors, with each end of the channel element opening out at a respective one of the connection ends.
  • the channel element can be designed according to a topology of the cable harness. This means that the channel element can have several channel branches, with the respective channel branch being arranged following a corresponding one of the strand branches.
  • the cable harness can also have at least one additional channel element.
  • the cable harness has a cable harness sheath, by means of which the individual conductor(s) and the duct element or duct elements are sheathed together along the direction of longitudinal extent—in particular without interruption along the direction of longitudinal extent.
  • a material connection is established between the cable harness sheath and the individual conductors or the individual conductors and the channel element or channel elements, so that the cable harness—apart from the hollow channel element—is blocked against a flow of a fluid, in particular air.
  • the channel element is hollow, it offers a material-free pressure equalization channel through which a fluid, in particular gas, for example air, can flow, by means of which pressure equalization can take place between the first connection end and the second connection end.
  • the cable harness has a dual functionality, namely - firstly - the cable harness is used as intended for transmitting the electrical power between the contact points and - secondly - the cable harness, in particular the channel element, acts as a pressure equalization element between the connection ends of the cable harness.
  • the duct element is particularly easy to use in an advantageous manner, in particular in the course of laying the cable loom to form an electrical network, because the duct element is an integral part of the cable loom. This is particularly advantageous if a pressure compensation element is to be formed subsequently, that is to say, for example, after a chamber or machine chamber has already been manufactured.
  • the cable harness due to the channel element that forms the pressure equalization channel, there is the possibility of retrofitting a pressure equalization element, namely the channel element, to an already existing chamber.

  • the dirt trapping device it is provided in this context--according to a development of the cable harness--that one, some or all of the dirt trapping devices have/have the additional length section.
