Definitions

  • the invention deals with charging sockets for electric vehicles.
  • a charging device is connected to the battery on board the vehicle via a charging cable and a charging plug and via the charging socket which is attached to the vehicle body and is accessible from the outside.
  • the charging plug When the charging plug is inserted into the charging socket, the power contacts of the charging socket are brought into engagement with corresponding mating contacts of the charging plug and are electrically connected.
  • the charging socket and the charging plug also have connectors for signal lines that are used to exchange control signals between the charger and the battery and the associated electronics in the vehicle.
  • the power cables are used to transfer the charging current from the power contacts of the charging socket to the battery.
  • Each charging cable has a central core with high conductivity, the cross-section of which is designed for a high charging current.
  • the central wire is coaxially surrounded from the inside to the outside by an inner insulation, an electrically conductive shielding sleeve that is to be connected to ground, and an outer insulation.
  • the central core of each charging cable is connected to one of the power contacts, and the shielding sleeve of each charging cable is electrically connected connected connected to the ground conductor arrangement, which in turn is connected to a ground contact of the battery.
  • the two power contacts are arranged side by side on one level, and the connected power cables also run parallel to one another on this level.
  • the ground conductor arrangement has shield tapping glasses with two axially parallel openings, through which the end sections of the charging cable, on which the outer insulation has been removed, are inserted in such a way that the shielding sleeves, which are then exposed and are usually formed from a braided shield, on the inner peripheral surface of the relevant opening of the shield tapping glasses abut so that an electrically conductive connection between the shielding sleeve and the shielding tap glasses is made.
  • the shielding sleeve and the inner insulation have also been removed at the ends of the power cables, and the central core is connected to the associated power contact at a certain distance from the shield tapping glasses.
  • the charging cables have a certain flexibility, they are relatively rigid due to the large cable cross-section of the central wire, so that the cables can only be laid in the vehicle with correspondingly large radii of curvature. This assumes that there is sufficient installation space in the vehicle.
  • the object of the invention is to create a charging socket that facilitates space-saving laying of the power cable.
  • This object is achieved according to the invention in that the ground conductor arrangement has at least two separate shield tapping elements, each connected to a ground conductor, which can be moved relative to one another in the longitudinal direction of the power cables.
  • the shield tapping elements can be moved relative to one another, they do not have to be at the same height in the longitudinal direction of the power cables. This makes it possible to arrange the power cables in such a way that their longitudinal axes already form an angle with the longitudinal axis of the respectively associated power contact at the location of the shield tapping elements. Consequently, the power cables can already be inclined or bent in a respectively desired direction on the end sections located between the power contacts and the shield tapping elements. This makes it easier to route the power cables past components that are located within the vehicle body at a certain distance behind the charging socket.
  • the ends of the conductive cores of the power cables can be connected to the power contacts via L-shaped contact lugs, the legs of which form an angle with each other that equals the angle between the Longitudinal axes of the power contacts and the longitudinal axes of the power cables are determined.
  • This angle can thus be easily varied by exchanging the contact lugs for those with a different angle or, if necessary, by bending them into a different shape.
  • the ground conductors connected to the shield tapping elements can have a flexible section within the charging socket, which allows the relative movement of the shield tapping elements.
  • the ends of these flexible sections opposite the shield tapping elements can then still be combined inside the charging socket to form a single ground conductor, which is led out of the housing via a bushing. Exemplary embodiments are explained in more detail below with reference to the drawing.
  • FIG. 1 a schematic perspective view of a
  • the charging socket shown in FIG. 1 has a so-called inlet 10 which can be screwed to a body part of a motor vehicle (not shown) with four screwing points 12 .
  • the inlet 10 has a hollow cylindrical insulator 14 which with respect to the
  • Vehicle body has to the outside and is arranged so that it - possibly after opening a flap in the vehicle body - from the outside is accessible, so that a plug of a charging cable can be plugged into the insulator 14.
  • a ring cover 26 is flanged to the contact carrier 16 and carries a coaxial holding piece 28 for an insulating housing 30, which is shown here only in broken lines and transparently.
  • Two parallel bushings 32 for the power cables 24 are formed in the bottom of the pot-shaped housing 30 .
  • the bottom of the housing 30 forms at least one passage 34 for a signal cable and at least one passage 36 for a ground conductor.
  • a longitudinal section of the peripheral wall of the housing 30 is designed as a bellows 52 so that the main part of the housing 30 is flexibly connected to the socket 28 of the annular cover 26 .
  • the axes of the cylindrical insulator 14 and the housing 30 are not coaxial, but they form an angle with each other. Accordingly, the axis of each power contact 18 also forms an angle with the axis of the associated power cable 24.
  • the inclination of the power cable 24 relative to the power contacts 18 is determined in the example shown by the shape of the L-shaped connection lugs 20, but can also be determined within certain limits by Bending of the portions of the power cables 24 lying within the housing 30 can be varied.
  • Such an inclination of the power cable 24 relative to the inlet 10 and thus also relative to the outer surface of the body can be advantageous, for example, if further inside the vehicle, on the right-hand side in FIG. are any vehicle components that the power cables 24 must be routed past.
  • the terminal lugs 20 are rigidly connected to the ends of the conductive wires 22 by ultrasonic welding, while the legs of these terminal lugs running transversely to the power contacts 18 are fixed to the ends of the power contacts by screw connections.
  • the configuration of inclination of the power cables 24 can thus be varied in the manufacture of the charging sockets, depending on the type of vehicle, by using terminal lugs 20 whose legs form a different angle with one another. If necessary, the legs of the terminal lugs connected to the conductive wires can also have a certain flexibility.
