Definitions

  • the present invention relates to a connector arrangement having the features of patent claim 1 and a plug connection having the features of patent claim 15.
  • Plug connections are used to transmit data signals and electrical supply currents.
  • the electrical contacting between the contact element of the connector and the associated counter-contact element of the counter-connector takes place in particular in electrical plug-in connections for high currents and high electrical voltages via contact lamellae arranged in between, which achieve sufficient contact pressure between the contact element and the counter-contact element.
  • From the DE 10 2013 217 256 B3 shows an example of a plug-in connection with a pin-shaped contact element, a socket-shaped mating contact element and a contact sleeve with individual contact lamellae arranged in between.
  • a connector is used, for example, in electric or hybrid vehicles in the charging path between the charging interface and the battery, in the traction path between the battery and the electric drive or in other high-voltage paths between the battery and other electrical units.
  • the object of the present invention is to create a plug-in connection, in particular for the transmission of higher currents or higher electrical voltages, which has a minimized transfer impedance between the contact elements and the associated mating contact elements.
  • the finding/idea on which the present invention is based is to minimize the number of contact transitions in the plug connection:
  • direct contact is realized between the contact partners of the connector and the mating connector without the interposition of a contact sleeve with contact lamellae.
  • the contact surface of the contact partner belonging to the connector is formed either directly in the individual electrical conductor or in a contact element formed in one piece with the individual electrical conductor.
  • At least one spring element is provided for each electrical conductor inserted into the connector, which in each case pushes the electrical conductor and thus the contact surface belonging to the electrical conductor against the associated mating contact surface in the mating connector pushes.
  • the electrical conductor is thus arranged between the spring element and the associated mating contact element.
  • the electrical conductors and the associated mating contact elements In order to minimize the installation space for the plug-in connection, when the electrical plug-in connection is in the plugged-in state, the electrical conductors and the associated mating contact elements must each be arranged in a direction that is orthogonal to the longitudinal axis of the electrical conductor and at the same time to the longitudinal axis of the mating contact elements.
  • the longitudinal axis of the electrical conductor and the associated mating contact element are thus laterally spaced from one another, ie in the direction of the transverse extension of the electrical conductor and the associated
  • Mating contact element arranged to each other.
  • a longitudinal extent or a longitudinal axis of a body is to be understood as meaning the greatest extent or the direction with the greatest extent of a body and a transverse extent as meaning the smaller extent of a body.
  • each electrical conductor or each contact element that is connected in one piece to the respective electrical conductor thus has a directional component that is orthogonal to the longitudinal axis of the electrical conductor or the mating contact element. Consequently, each spring element that is connected to an electrical conductor presses the contact surface of the electrical conductor or the contact surface of the contact element integrally connected to the electrical conductor in a first orthogonal direction to the longitudinal axis of the electrical conductor against the mating contact surface on the associated mating contact element.
  • a constant and sufficient force is exerted by the individual spring elements in a first direction orthogonal to the longitudinal axis of the electrical conductor from the contact surface to the associated mating contact surface.
  • the contact surface which is designed to be complementary to the counter-contact surface, consequently contacts the associated counter-contact surface over the entire surface without enclosing air. Oxidation or corrosion of the contact surface and the counter-contact surface is thus advantageously ruled out. A deterioration in the transfer impedance due to surface oxidation on the contact and counter-contact surfaces over the operating period can thus also be avoided.
  • the connector arrangement is preferably a connector arrangement for the transmission of a high current or a high electrical voltage. Under a high current is here and In the following, a current to be transmitted between typically 300 A and 600 A is understood in an electric or hybrid vehicle.
  • the range of high electrical voltage to be transmitted in an electric or hybrid vehicle is preferably between 450 V and 1500 V and more preferably between 750 V and 1000 V.

  • an electrical flat conductor is understood to mean an electrical conductor with a first transverse extent and a second transverse extent, in which the first transverse extent is larger, preferably a multiple larger, than the second transverse extent.
  • the surface of the electrical flat conductor formed by the first transverse extent and the longitudinal extent is preferably of planar design.
  • the first transverse extent of the electrical flat conductor is aligned orthogonally to the second transverse extent, and a rectangular cross-sectional profile is thus realized.
  • the flat electrical conductor can be used as a busbar, i. H. be designed as a rigid electrical flat conductor, or as a cable whose strands are compacted to each other at the axial end. In the latter case, the electrical flat conductor is rigid at least in an axial end area. Finally, due to its dimensioning and the material used, the electrical flat conductor can also have a certain bending elasticity for flexible laying in the body of the electric or hybrid vehicle.
  • Two electrical conductors for transmitting a direct or alternating current are preferably inserted in the connector arrangement.
  • three electrical conductors are also conceivable for the transmission of a three-phase current or an integer multiple of pairs of electrical conductors for the transmission of several direct and/or alternating currents.

  • the connector housing For contacting the electrical conductors with associated mating contact elements, the connector housing has a further opening through which the mating contact elements of the mating connector can be inserted into a common receiving chamber or into individual receiving chambers within the connector housing.
  • the connector housing must be made of a suitable dielectric material and dimensioned appropriately in order to meet the dielectric strength requirements in the clearance and creepage distances necessary for the transmission of high currents or high electrical voltages.

  • the contact surface for the directional component which is directed in a first orthogonal direction to the longitudinal axis direction of the electrical conductor, also has a directional component in a second orthogonal direction to the longitudinal axis direction of the electrical conductor and to the first orthogonal direction. Consequently, the mating contact surface of the associated mating contact element not only has a directional component directed in a direction orthogonal to the longitudinal axis direction of the mating contact element, but also a directional component in the longitudinal axis direction of the mating contact element.
  • a fastening element is arranged in the connector housing, which is set up to realize a fastening of the connector to the mating connector with a corresponding fastening element in the mating connector.
  • the fastening element of the connector and the complementary fastening element of the mating connector bring about sufficient contact pressure between the contact surfaces and the associated mating contact surfaces in the longitudinal axis direction of the mating contact element.
