Description

Es sind keramische Dürchführungs'kondensatoren bekannt, die aus einem keramischen Röhrchen von z. B. 4 mm Durchmesser und 2o bis 5-o mm Länge bestehen, wobei das Röhrchen in eine mit einem Gewinde versehene Buchse eingelötet ist, die die Kontaktgabe mit Erde oder Masse herstellt. Der Durchführungsdraht ist an einem oder an beiden Enden des Innenbelages durch Lötung lkontaktiert. Durch Verwendung von keramischen Massen mit sehr großer Dielektrizitätskonstante können. auf diese Art Kapazitäten erreicht werden, die jedoch den Wert von 2-o ooo .pF kaum überschreiten. Für größere Kapazitäten müssen entweder der Rofhrdurchmesser stark vergrößert oder die Wandstärke erheblich verkleinert werden, so daß entweder die räumlichen Abmessungen für hohe Frequenzen, zu groß oder die Spannungsfestigkeit zu.klelin werden oder beides eintritt.There are ceramic Dürchführung'kondensatoren known, which consist of a ceramic tubes of z. B. 4 mm in diameter and 2o to 5-o mm in length, wherein the tube is soldered into a threaded socket, the making contact with earth or ground. The lead-through wire is on one or oil-contacted at both ends of the inner lining by soldering. By using of ceramic masses with a very high dielectric constant. to this Kind of capacities can be achieved, which, however, hardly exceed the value of 2,000 pF. For larger capacities, either the tube diameter must be increased or the wall thickness can be reduced considerably, so that either the spatial dimensions for high frequencies, too large or the dielectric strength too.klelin or both occur.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß konzentrisch um den die Durchführung enthaltenden Kondensator mehrere, insbesondere keramische Röhrchenkonden,satoren angeordnet sind, deren Inneivbeläge mit dem Innenbelag des Durchführungskondensators elektrisch verbunden und deren Außenbeläge über das Gehäuse geerdet bzw. an Masse gelegt sind. Zweckmäßig sind die Innenbeläge aller Röhrchen mit dem Durchführungsdraht und die Außenbeläge durch eine ringförmige Leitung mit dem Gehäuse bzw. der Gewindebuchse dies Durchführungsköndensators verbunden. Hierdurch erreicht man Kapazitäten bis beispielsweise roo ooo pF, die infolge der konzentrischen. Anordnung und der verhältnismäßig kleinen Abmessungen bis zu einer hohen Frequenz einsetzbar sind. Der die Durchführung tragende Kondensator sowie die konzentrisch, um diesen angeordneten Kondensatoren sind innenhalb eines Gehäuses angeordnet, welches die CTewindebuchse für den Anschluß trägt.According to the invention, these disadvantages are avoided in that concentrically around the condenser containing the implementation several, in particular Ceramic tubular condensers, capacitors are arranged, their inner linings with the inner lining of the lead-through capacitor and their outer linings via the Housing are earthed or connected to earth. The interior coverings are all functional Tubes with the lead-through wire and the outer coverings through a ring-shaped conduit this bushing condenser is connected to the housing or the threaded bushing. This achieves capacities up to, for example, roo ooo pF, which as a result of the concentric. Arrangement and the relatively small dimensions up to one high frequency can be used. The condenser carrying the implementation as well as the concentrically arranged capacitors are inside a housing arranged, which carries the C thread socket for the connection.

In den Fig. i und 2 ist ein Ausführungsbeispiel der Erfindung dargestellt. Der von den keramischen Röhrchen i gebildete Durchführungskondensator mit .dem Durchführungsdraht 2 ist konzentrisch von -vier weiteren Röhrchenkondensatoren 3, 4, 5,, 6 umgeben. Die Innernbeläget 7 dieser Kondensatoren sind mit dem Innenbelag 8 des Durchführungskondensators elektrisch verbunden, während die Außenbeläge 9 der Röh.rchenkondensatOren 3 bis 6 mit dem Außenbelag io des Durchführungskondensators i und: mit dem Gehäuse i i verbunden bzw. über dieses geerdet sind. Das Gehäuse ii trägt die Anschlußbuchse 12. Der Durchführungsdraht z ist durch eine Glas- oder Keramikperle 13 bzw. eine Glaseinschmelzung oder ein. ikeramisches Rohr 14 gegenüber dem Gehäuse i i isoliert.In Figs. I and 2, an embodiment of the invention is shown. The lead-through capacitor formed by the ceramic tube i with the lead-through wire 2 is concentrically surrounded by four further tubular capacitors 3, 4, 5, 6. The inner lining 7 of these capacitors are connected to the inner lining 8 of the bushing capacitor electrically connected, while the outer coverings 9 of the Röh.rchenkondensatOren 3 to 6 with the outer coating io of the feed-through capacitor i and: with the housing i i are connected or grounded via this. The housing ii carries the connection socket 12. The feed-through wire z is through a glass or ceramic bead 13 or a Glass seal or a. Ceramic tube 14 isolated from the housing i i.
