Ss ist Aufgabe der Erfindung die Konstruktion solcher Vakuumschalter zu vereinfachen und die Anfälligkeit gegen etwaige Undichtigkeiten des Gehäuses zu vermindern.Ss the object of the invention is the construction of such vacuum switches to simplify and the susceptibility to any leaks of the housing.

Dies wird dadurch erreicht, daß.erfindungsgemäß das Hochvakuumgefäß aus einem elastischen Mittelteil aus Metall besteht,.dessen Enden nach innen umgebördelt sind und daß an die umgebördelten -Enden Kappen aus nichtleitendem Material vakuumdicht angeglast sind. Als Mittelteil kann vorzugsweise ein Metallwellrohr vorgesehen sein. Die Kappen können z.B. aus Glas oder Keramik bestehen.This is achieved in that, according to the invention, the high vacuum vessel consists of an elastic middle part made of metal,. whose ends are crimped inwards and that on the crimped ends Caps made of non-conductive material are glazed in a vacuum-tight manner. as A corrugated metal pipe can preferably be provided in the middle part. The caps can be made of glass or ceramic, for example.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung beschrieben.The following is an embodiment of the invention based on a Drawing described.

Das Hochvakuumgefäß besteht aus einem elastischen Mittelteil 1t z»B, einem Metallwellrohr, dessen Enden 4, 4' nach innen uffigebördelt sind. .An die umgebördelten Enden 4, 4' sind Glaskappen 2,. 3 vakuumdicht angeglast. Bas HochvakuumgefäQ enthält ferner zwei gleichachsig angeord nete aneinanderstoßende Schaltkontakte 5, 6, die mit stromführenden Kontakt stiften 7 > 8 in Verbindung stehen. Die -Glaskapipen 2 bzw-» 3 sind über Metallringe 9 mit den Kontaktstiften fγ 8 vatoramtiemt 4 bunden. Die Motallringe 9 und das le tall wellrohr 1 können z.B.. einer GoM~I»egierung bestehen. Der ein« Sctealtfc.©ii%aäc1i;<, se der Schaltkontakt 6, ist mit seinem Kontaktstü.S'ib M Iweweglieto.The high-vacuum vessel consisting of an elastic central part 1 t z »B, a metal corrugated pipe, the ends 4, 4 'uffigebördelt inward. . At the beaded ends 4, 4 'are glass caps 2,. 3 vacuum-tight glazed. Bas high vacuum vessel also contains two coaxially arranged abutting switch contacts 5, 6, which are connected to current-carrying contact pins 7-8. The glass caps 2 or 3 are bound to the contact pins f γ 8 vatoramtiemt 4 via metal rings 9. The Motallringe 9 and the le tall corrugated pipe 1 can, for example. exist in a GoM organization.

verhindern die Bedampfung der doppelten Anglasung. Das Metallwellrohr wirkt als potentialfreier Schirm. Das verhältnismäßig lange Metallwellrohr wird mechanisch nur schwach beansprucht. Der bei den bekannten Konstruktionen in Kontakthöhe angebrachte Schirm und das für den beweglichen Kontakt notwendige Sinterlager entfallen. Dadurch ist eine schlanke Konstruktion des Vakuumschalters möglich, so daß kompakte Schütze gebaut werden können.prevent vaporization of the double glazing. The corrugated metal pipe acts as a potential-free screen. The relatively long corrugated metal pipe is only slightly mechanically stressed. The one with the known Structures attached at the contact height screen and the sintered bearing necessary for the movable contact are not required. Through this a slim construction of the vacuum switch is possible so that compact contactors can be built.
