Definitions

  • the invention relates to a current lead-through for K old- temaschinen with hermetically sealed compressors.
  • Known current feedthroughs consist of a metal base and, as a rule, three current-carrying pins made of alloy steel which are melted into glass.
  • the object of the present invention is therefore seen in simplifying manufacture and assembly, reducing costs and increasing operational reliability when carrying out a current with an insulating body penetrated by electrically conductive pins.
  • This is inventively achieved by selecting an insulating body eraturbe drillingm from temperature-p against. Chemical resistant and at least slightly elastic material, in particular flastomer, thermoplastic or the like. This achieves a g as-tight anchorage of the passage in the compressor capsule and a reliable electrical isolation of the conductive pins against the same.
  • melting-only steel pins can be used, while the invention, the Anord - voltage of electrically more conductive brass pins allows.
  • one or more knobs receiving the pins are arranged on a disk-shaped base. This results in a gas-tight connection between the pins and the knobs and thus the overall implementation.
  • the base and the knobs are preferably injection-molded in one piece, so that there is a particularly simple type of manufacture.
  • each knob has a cylindrical part and a conical part at its free end.
  • an annular bead is arranged at the transition between the cylindrical and the conical part of the knob.
  • the capsule wall rests on the knob between the disc and this bead, which on the one hand indicates that the bushing is properly installed and serves as a resistance to the bushing being pressed out of the capsule.
  • the base expediently has an annular bead directed parallel to it on the lower cylindrical part of each knob. This serves as a system for the capsule wall and for sealing it ben. Between each pin and the bushing there is preferably a recess with an annular cross section, which extends from the base to approximately the end of the cylindrical knob part. On the one hand, this makes assembly of the bushing easier, since it can be compressed when it is inserted, and there is also an additional seal with respect to the capsule, since the internal pressure lies against the wall of the bushing. It is also possible in this way to dismantle the bushing without having to destroy it.
  • the base In order to reinforce the base, the base has a flange projecting beyond the cylindrical part of the knob. In the case of melted-in pins, expensive contact plates have to be welded on, while according to the invention only contact surfaces are pressed onto the pins.
  • the current feedthrough is designed as a disk-shaped base 1 and consists of electrically non-conductive elastomer or thermoplastic. At its upper end, the base has three knobs 2, in each of which an electrically conductive pin 3 is embedded centrally. The base 1 and the knobs 2 are off sprayed in one piece. The freely protruding pin ends 4 can, depending on the electrical power to be transmitted, be designed with or without an antatata contact surface.
  • the knobs 2 have a conical part 5 on the end face, which is used for centering during the finely buttoning process in the compressor capsule (not shown).
  • the adjoining cylindrical part 6 is to a certain extent larger than the associated bore of the capsule, also not shown, and serves as the actual sealing element of the entire bushing.
  • annular bead 7 is arranged, on which the capsule wall, not shown, bears after assembly. It indicates the correct assembly of the bushing and also serves as a stop for the compressor capsule to prevent the bushing from sliding out unintentionally.
  • the base 1 is reinforced by a flange 8 projecting beyond the cylindrical part 6 of the knobs 2. This serves as a system for carrying out the capsule wall, which abuts the annular bead 10, which also contribute to the sealing.
  • each pin 3 and the bushing there is a recess 9 with an annular cross section, which extends from the socket 1 to approximately the end of the cylindrical knob part 6.
  • the cylindrical part 6 of the knob 2 is slightly larger held as the associated hole in the capsule, and the annular recess enables the resilience of the knob 2 thus obtained to facilitate pushing into the capsule.
  • the internal pressure is applied against the wall of the recess, so that this results in an additional seal.
  • the connection between the pins 3, which are made of brass or iron, with the knobs 2 is gas-tight.
