  • Process for producing a vacuum interrupter chamber
    Patent number: 5222651
    Abstract: A process for producing a vacuum interrupter chamber includes placing spacers in bodily contact with a soldering foil and joining the spacers to the soldering foil or fixing them in a displacement-proof fashion on specially made dents in the foil, so that they can be fixed for the purpose of a reliable and simple assembly. Degassing gaps are left between soldering spacers, on which a cover of the interrupter chamber rests. The vacuum interrupter chamber is evacuated in a single furnace cycle and soldered.
