  • Patent number: 6574864
    Abstract: A method for manufacturing a contract arrangement for a vacuum switching tube having a contact carrier and a contact piece joined to the contact carrier in a vacuum using soldering material. The contact carrier is made of electrically highly conductive material, for example, copper, and the contact piece is made of a flame-resistant sintering material containing copper. The contact piece is pressed flat directly onto the contact carrier, generating a gap along the contact surface, and the soldering material is arranged on areas directly bordering the gap of the contact surface between the contact piece and the contact carrier. Subsequently, in a vacuum through the application of heat, the soldering material is brought to the melting point, and the molten soldering material penetrates into the gap of the contact surfaces between the contact carrier and the contact piece.

  • Patent number: 6476366
    Abstract: A device for degassing and brazing preassembled vacuum interrupters in only one brazing operation includes a base plate having at least one brazing site which features an opening of the base plate for connecting a suction pump and a bell which covers the opening and can be put on the base plate and lifted off. The bell is surrounded on the outside by an excitation coil to which medium- or high-frequency energy can be applied. The device includes a medium- or high-frequency generator for the excitation coil and with a cylindrical tubular susceptor arranged inside the bell for receiving at least one preassembled vacuum interrupter.
