Definitions

  • the present invention relates to an arrangement for sealing a high-voltage interface, in particular to an arrangement comprising a housing and a busbar for connecting a housing provided in the circuit arrangement with an existing outside of the housing power source or current sink, wherein the housing has an opening, from the busbar protrudes.
  • the object of the invention is to provide a generic arrangement in which electronic components of a power electronics are housed protected media-tight while ensuring a high-voltage supply.
  • the invention proceeds from an arrangement comprising a housing and a busbar for connecting a circuit arrangement present in the housing to a current source or current sink existing outside the housing, the housing having an opening from which the busbar projects.
  • the arrangement is characterized by a breakthrough cross-holding element for the busbar, wherein the holding element surrounds the busbar. Further, between the busbar and the holding element, a first seal is present and between the holding element and housing a breakthrough circumferential second seal.
  • the busbar support member having the second seal is connected to the housing for the circuitry, e.g. sealed the power electronics.
  • the bus bar on a circumferential recess, in which the first seal is inserted.
  • the circumferential indentation is designed such that the first seal is displaceable within the indentation in the longitudinal direction of the conductor rail.
  • the housing has a groove in which the second seal is inserted.
  • the depth and width of the groove is designed such that the second seal is squeezed or compressed in the groove during the merging of the holding element and the housing by the holding element.
  • a holder is present, which presses the holder element for the busbar against the housing. With this holder on the one hand an attachment of the retaining element is made on the housing and on the other hand, a pressing force built up for pressing the second seal between the retaining element and the housing.
  • FIG. 1 shows an exemplary schematic sectional view through an inventive arrangement with a busbar
  • Fig. 3 is an exemplary illustration of an arrangement according to the invention with a holder for the holding element of the busbar.
  • Fig. 1 shows an exemplary schematic sectional view of an inventive arrangement with a busbar.
  • the arrangement has a housing 5 with an opening 5a, a busbar 1 and a holding element 2 for the busbar 1.
  • the busbar 1 is enclosed by the holding element 2.
  • the holding element 2 and the busbar 1 engage through the opening 5a, so that a first portion of the holding element 2 and a first portion of the busbar 1 are within the housing 5 and a respective second section outside the housing 5.
  • the busbar 1 has a first end 1 b, which is connected to a (not shown) power electronics within the housing 5.
  • the busbar 1 has a second end 1 c, which is connected to a (not shown) power source or current sink outside the housing 5.
  • a power source can be a battery or a generator.
  • a current sink may be an electrical consumer, e.g. an electric machine.
  • the holding element 2 has an inner surface 2c, which faces the busbar 1.
  • the busbar 1 has an um- ongoing indentation 1 a on.
  • a circumferential sealing element 3 is arranged in this recess 1 a. This sealing element 3 bears against the inner surface 2c of the holding element 2 and thus seals the holding element 2 against the busbar 1.
  • the dimension of the recess 1 a is formed such that in the longitudinal direction Z, the width z of the recess 1 a is greater than the diameter of the sealing element 3. This ensures that the sealing element 3 is displaceable within the recess 3 in the Z direction, to optionally absorb vibrations or displacement forces as well as tolerances of the components or tolerances during assembly while ensuring a reliable seal.
  • the recess 1 a is further formed such that the depth T is smaller than the diameter of the sealing element 3. This ensures that the sealing element 3 is compressed between the busbar 1 and retaining element 3.
  • the housing 5 has a groove 5b.
  • This groove 5b runs as a closed curve around the aperture 5a in the housing 5 around.
  • a second sealing element 4 is arranged in the groove 5b.
  • the dimensions of the groove 5b are chosen such that the sealing element 4 protrudes from the groove 5b, i. the sealing element 4 projects, relative to the upper side 5d of the housing 5.
  • the holding element 2 forms a collar 2b.
  • This collar 2b rests against the housing 5 and serves inter alia as a stop for the retaining element 2 on the upper side 5d of the housing 5.
  • the underside 2d of the collar 2b is designed essentially parallel to the upper side 5d of the housing 5.
  • the collar 2b of the retaining element 2 presses the second sealing element 4 during insertion of the retaining element 2 in the opening 5a in the groove 5b.
  • a fastening means By means of a fastening means, the holding element 2 is pressed and held in the direction of the housing 5.
  • a fastening means is shown by way of example in FIG. 3.
  • FIG. 2 shows an exemplary schematic sectional view of an inventive arrangement with two bus bars.
  • the arrangement has two bus bars 1, 1 1, each with a holding element 2, 22 and, respectively, a common holding element.
  • the holding elements 2, 22 are in particular electrically insulating, so that between the busbar 1, 1 1 and the housing 5 or other components, not shown, an electrical short circuit can occur.
  • the housing 5 has an opening 5a, which is covered by the holding element 2, 22.
  • a groove 4a is made on the upper side 5d of the housing 5, in which a sealing element 4 is inserted, which seals the retaining element 2, 22 against the housing 5.
  • a bracket 6 is provided, which is connected on the one hand to the housing 5, e.g. via a screw connection and on the other hand presses on the holding element 2, 22 and thereby causes a contact pressure on the holding element 2, 22 in the direction of the housing 5.
  • the holder 6, which presses the holding element 2 for the busbar 1 against the housing 5 can be seen in Fig. 3.
  • the holder 6 extends in the form of a closed curve, for example in an annular manner around the holding element 2 and lies on the upper side 2e of the collar 2b.
  • the holder 6 is fastened to the housing 5 by means of a screw 7.
