Description

Bei den Elektrodeneinführungen für Vakuumgefäße aus Metall besteht die Schwierigkeit, daß die Elektrode isoliert durch die Metallwandung hindurchgeführt werden muß und die Durchführungsstelle einerseits luftdicht, anderseits wärmebeständig sein muß. Die Erfindung hat eine Elektrodeneinführung für Vakuumgeiäße aus Metall zum Gegenstand, die auch bei schwierigen Verhältnissen luftdichten Abschluß und Wä: mebtständigkeit gewährleistet.With the electrode inlets for vacuum vessels made of metal, the problem arises that the electrode must be insulated and passed through the metal wall and the lead-through point must be airtight on the one hand, and heat-resistant on the other. The invention has one Electrode insertion for vacuum vessels made of metal to the subject, even with difficult Conditions airtight closure and warmth guaranteed.

Bei der Anordnung gemäß der Erfindung wird die Elektrode nicht unmittelbar in der Gefäßwandung befestigt und gegen diese isoliert, sondern sie wird frei durch die Gefäßwandung hindurchgeführt. Der Durchführungsisolator liegt über der Gefäßwandung und ist mittels einer Metallkappe luftdicht an ihr befestigt. Da die Kappe verhältnismäßig nachgiebig ist, kann sich bei Erwärmung die Metallwandung beliebig dehnen, ohne daß auf den Isolator ungünstige Temperaturspannungen einwirken. Die Elektrode kann nunmehr mittels einer zweiten Kappe am Durchführungsisolator befestigt werden. Die zu verbindenden Teile aus verschiedenem Material werden dann durch einen Metallfluß miteinander verbunden, wie es für die Verbindung von Metallen und Isolierstoff bekannt geworden ist.In the arrangement according to the invention, the electrode is not fastened directly in the vessel wall and insulated from it, but it is guided freely through the vessel wall. The bushing insulator lies over the vessel wall and is attached to it in an airtight manner by means of a metal cap. Since the cap is relatively flexible, the metal wall can expand as desired when heated without unfavorable temperature stresses acting on the insulator. The electrode can now be attached to the bushing insulator by means of a second cap. The parts to be connected made of different materials are then connected to one another by a metal flow, as has become known for the connection of metals and insulating material.

In der Abbildung ist als Beispiel der Erfindung die Elektrodeneinführung eines Vakuumapparates, ζ. Β. eines Quecksilbergleichrichters, gezeichnet. 1 ist die Elektrode, 2 das Vakuumgefäß, 3 ein ringförmiger Porzellankörper. 4 und 5 sind die beiden Metallkappen, die durch den Metallfluß 6 und 7 mit dem Porzellankörper verbunden sind. Die obere Metallkappe ist an die Elektrode 1 angelötet, angeschweißt oder sonstwie luftdicht mit ihr verbunden, die untere Metallkappe an das Gleichrichtergefäß 2. Die Elektrode ist somit luftdicht und isoliert gegen das Gefäß eingeführt.As an example of the invention, the illustration shows the electrode insertion of a vacuum apparatus, ζ. Β. of a mercury rectifier, drawn. 1 is the electrode, 2 is that Vacuum vessel, 3 an annular porcelain body. 4 and 5 are the two metal caps, which are connected to the porcelain body by the metal flow 6 and 7. The top metal cap is soldered, welded or otherwise air-tight to the electrode 1, the lower metal cap to the rectifier vessel 2. The electrode is thus airtight and insulated against the vessel.

Durch die Anordnung gemäß der Erfindung können sich die von Temperatur verschieden beanspruchten Teile, wie Isolierkörper und Metallteile, unbeeinflußt voneinander frei ausdehnen, so daß Wärmespannungen auf die nachgiebigen Metallkappen vermieden sind.Due to the arrangement according to the invention, the temperature can be stressed differently Parts, such as insulators and metal parts, expand freely, unaffected by one another, so that thermal stresses on the flexible metal caps are avoided.

Zum Vergießen der Metallkappen mit dem Porzellankörper können beliebige Metalle, wie Zinn, Blei, Zink, verwendet werden oder Metallegierungen. Ein möglichst hoher Schmelzpunkt ist erwünscht, wenn die Verbindung gegen hohe Temperaturen Stand halten soll. Das Porzellan wird zweckmäßig an den Dichtungsstellen nicht glasiert, um ein besseres Anhaften des Schmelzflusses zu erzielen. Auch empfiehlt es sich, zu dem gleichen Zweck die Dichtungsstellen aufzurauhen oder mit Rillen oder ähnlichen Unebenheiten der Oberfläche zu versehen.Any metals, such as Tin, lead, zinc, or metal alloys can be used. A melting point as high as possible is desirable if the connection is to withstand high temperatures. The porcelain it is advisable not to glaze the sealing points to ensure better adhesion of the To achieve melt flow. It is also advisable to use the sealing points for the same purpose rough or with grooves or similar bumps to provide the surface.
