Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Durchführung für ein evakuiertes Gehäuse, umfassend umfassend einen im wesentlichen drehsymmetrischen Isolationskörper mit einer Innenbohrung, ein in der Innenbohrung aufgenommenes elektrisch leitendes Verbindungsteil. The invention relates to a bushing for an evacuated housing, comprising a substantially rotationally symmetrical insulation body with an inner bore, a recorded in the inner bore electrically conductive connecting part.
In der Praxis tritt häufig die Forderung auf, für ein evakuiertes Gehäuse eine vakuumdichte Durchführung vorzusehen, wobei die Durchführung elektrisch leitend ausgebildet sein muss, um Signale bzw. elektrische Energie aus dem evakuierten Gehäuse nach außen leiten zu können. Diese Forderung tritt beispielsweise in Zusammenhang mit Schwungmassenspeichern auf, die in einem evakuierten Gehäuse gelagert sind, für die jedoch elektrisch leitende Durchführungen in der Wandung des Gehäuses vorgesehen sein müssen. In practice, the requirement often arises to provide a vacuum-tight passage for an evacuated housing, wherein the passage must be designed to be electrically conductive in order to be able to conduct signals or electrical energy out of the evacuated housing to the outside. This requirement occurs, for example, in connection with flywheel mass accumulators, which are mounted in an evacuated housing, but for which electrically conductive bushings in the wall of the housing must be provided.
Aufgabe der ErfindungObject of the invention
Es ist die Aufgabe der Erfindung, eine einfach zu montierende vakuumdichte Durchführung für insbesondere hohe Stromstärken anzugeben. It is the object of the invention to provide an easy-to-install vacuum-tight implementation for particularly high currents.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Durchführung für ein evakuiertes Gehäuse, insbesondere für einen Schwungmassenspeicher, umfassend einen im wesentlichen drehsymmetrischen Isolationskörper mit einer Innenbohrung, ein in der Innenbohrung aufgenommenes elektrisch leitendes Verbindungsteil, wobei der Isolationskörper einen radial abstehendes Flanschteil aufweist, das eine erste Stufe an einer äußeren Mantelfläche ausbildet, und wobei die Innenbohrung des Isolationskörpers eine zweite Stufe ausbildet. An den beiden Stufen des Isolationskörpers lassen sich Dichtelemente, beispielsweise O-Ringe, anordnen und abstützen. Das radial abstehende Flanschteil ist dabei ein Abschnitt des Isolationskörpers und insbesondere mit diesem einteilig ausgebildet. This object is achieved by a passage for an evacuated housing, in particular for a flywheel energy storage, comprising a substantially rotationally symmetrical insulating body with an inner bore, a received in the inner bore electrically conductive connecting part, wherein the insulating body has a radially projecting flange portion having a first stage forms on an outer circumferential surface, and wherein the inner bore of the insulating body forms a second stage. At the two stages of the insulating body, sealing elements, such as O-rings, can be arranged and supported. The radially projecting flange is in this case a portion of the insulating body and in particular integrally formed therewith.
Vorzugsweise ist vorgesehen, dass das Flanschteil eine Montagestufe aufweist, an der ein Fixierring festlegbar ist. Durch den Fixierring wird das Flanschteil außen auf die Wandung des Gehäuses gedrückt und eine vakuumdichte Abdichtung zwischen dem Isolationskörper und der Wandung des Gehäuses erzielt. Preferably, it is provided that the flange part has a mounting step, on which a fixing ring can be fixed. By the fixing ring, the flange is pressed outside on the wall of the housing and achieved a vacuum-tight seal between the insulating body and the wall of the housing.
Vorzugsweise ist vorgesehen, dass in einem ersten Abschnitt der Innenbohrung zwischen dem Verbindungsteil und der Innenwandung der Innenbohrung ein elektrischer Isolationsschlauch angeordnet ist.It is preferably provided that an electrical insulation hose is arranged in a first portion of the inner bore between the connecting part and the inner wall of the inner bore.
Vorzugsweise ist vorgesehen, dass das Korpus des Isolationskörpers aus einem Kunststoff oder einem keramisch beschichteten metallischen Grundkörper ausgebildet ist.It is preferably provided that the body of the insulating body is formed of a plastic or a ceramic-coated metallic base body.
Die Erfindung betrifft weiter ein evakuiertes Gehäuse, umfassend eine Bohrung in einer Wandung des Gehäuses und eine in der Bohrung aufgenommene erfindungsgemäße Durchführung, insbesondere ein solches Gehäuse, in dem eine Schwungmasse eines Schwungmassenspeichers schnelldrehend gelagert aufgenommen ist. The invention further relates to an evacuated housing, comprising a bore in a wall of the housing and a recorded in the bore inventive implementation, in particular such a housing in which a flywheel mass of a flywheel mass storage is added quickly rotating stored.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie aus der Beschreibung eines Ausführungsbeispiels. Further advantages and features of the invention will become apparent from the dependent claims and from the description of an embodiment.
Die Erfindung wird im Folgenden unter Bezugnahme auf die anliegende Zeichnung näher beschrieben und erläutert. The invention will be described and explained in more detail below with reference to the accompanying drawings.
