Definitions

  • the invention relates to an electrical feedthrough with a feedthrough conductor and an insulating body surrounding the feedthrough conductor, with a fastening flange anchored in the insulating body, on the inner circumference of which a shielding body controlling the electric field is arranged, and with a capacitive voltage tap provided for the operation of a display device , consisting of a tapping electrode concentrically surrounding the lead-through conductor inside the insulating body and a connecting element connected to it and accessible on the outside of the insulating body.
  • the field-controlling shielding body which has a sleeve-shaped section, is designed here as a one-piece molded body made of a rubber-elastic, electrically conductive material. It is cast in the insulating body and is concentric with the feed-through conductor.
  • the tap electrode consists of a metallic ring, for example made of wire, connected to a support device which is centered by the sleeve-shaped section of the shielding body.
  • a plurality of support members emanate from the ring and lie against the outer jacket of the sleeve-shaped section of the shielding body with the interposition of electrical insulation.
  • the entire support device is fixed coaxially to the feed-through conductor on the shielding body.
  • the insulation consisting of strips of film is glued to the support members.
  • the connecting element which is designed, for example, as a contact tab, is fastened to one of the support members.
  • the invention is therefore based on the object of improving and simplifying the electrical feedthrough with regard to its tap electrode.
  • the tap electrode is designed as an insulating ring body provided with an outer conductive layer, which has at least three support feet which extend over the shielding body, one of which supports the connecting element connected to the conductive layer.
  • FIG. 1 shows an electrical feedthrough which is constructed from an insulating body, one from the insulating body 3 surrounded leadthrough conductor 2, a mounting flange 4, a field-controlling shielding body 5 and a capacitively coupled tap electrode for operating a voltage display device.
  • the structure and the arrangement of the shielding body 4 and the fastening flange 5 in the bushing 1 are unchanged from the prior art mentioned at the beginning, on which the invention is based.
  • the tap electrode is designed as an annular body 6 (see FIG. 2) made of plastic, which is connected to a conductive layer 7, e.g. a conductive lacquer, is provided and has at least three support feet 8 which extend over the shielding body 5.
  • the one support leg 8 carries a connection element 10, which is accessible on the outside 9 of the insulating body 3, e.g. a contact flag for coupling the voltage display device.
  • the support feet 8 are adapted in terms of cross-section and inclination to the longitudinal axis of the bushing 1 to the annular shielding body 5 such that, in the assembled state, a clamping fit of the ring body 6 on the shielding body 5 results before the insulating body 3 is potted.
  • the support feet 8 are provided according to FIG 2 with a circumferentially arranged collar 13. On the inside, the support feet have two sharp-edged or pointed projections 12 for anchoring in the shielding body 5 (see FIG. 3). Both Measures are used to securely anchor the tap electrode 6, 7, 8 in the insulating body 3.
