Abstract

The invention relates to a packing between metallic elements which is surrounded by a metal foil, thus fulfilling the function of protective conductor as defined in DIN VDE 0100 part S40.

Description

Die Erfindung betrifft eine Dichtung zwischen mindestens zwei metallischen Bauteilen.The invention relates to a seal between at least two metallic components.

Für Flachdichtungen werden zwischen zwei Bauteilen üblicher­ weise die Standarddichtwerkstoffe (Elastomere, Elastomere mit Fasern bzw. Füllstoffen, zellige Materialien) verwendet. Me­ tallische Bauteilen sind jedoch dabei gegeneinander isoliert.Flat gaskets are becoming more common between two components the standard sealing materials (elastomers, elastomers with Fibers or fillers, cellular materials) are used. Me However, metallic components are isolated from each other.

Um gefährliche Körperströme zu vermeiden, müssen die Bauteile jedoch elektrisch leitend verbunden sein (Spezifikation des Schutzleiters in DIN VDE 0100 Teil 540). Konstruktiv kann ei­ ne elektrisch leitende Verbindung zwischen den Bauteilen her­ gestellt werden mittels auf Block gehenden Nocken, mit Schrauben, mit Paßstiften oder eigenen Erdungsleitern.In order to avoid dangerous body currents, the components however, be electrically connected (specification of the Protective conductor in DIN VDE 0100 part 540). Constructively, egg ne electrically conductive connection between the components are set by means of cams going on block, with Screws, with dowel pins or own earthing conductors.

Es gibt außerdem leitfähige Flachdichtungen, wie Graphit-, und Metalldichtungen oder auch Dichtungen mit leitfähigen Füllstoffen, speziell für EMV-Anwendungen. Von Nachteil ist dabei oft der große spezifische Widerstand bzw. die mangelnde Dichtfähigkeit.There are also conductive flat gaskets, such as graphite, and metal seals or also seals with conductive Fillers, especially for EMC applications. The disadvantage is often the high specific resistance or the lack of it Sealability.

Mit Stahlinnenbördeln versehene Ringdichtungen werden gemäß Hecker Katalog "Hecker Dichtungsplatten DIN 28091" zur Erhö­ hung der Druckbeständigkeit und Ausblassicherheit verwendet.Ring seals with steel inner flanges are manufactured according to Hecker catalog "Hecker gasket sheets DIN 28091" to increase pressure resistance and blow-out safety.

Die Aufgabe der Erfindung besteht darin, mit einfachen Mit­ teln ohne Änderung bestehender Konstruktionsprinzipien eine leitfähige Dichtung zu schaffen, die sowohl gute Dichtwirkung aufweist, als auch die Schutzleiterfunktion gemäß DIN VDE 0100 Teil 540 erfüllt. The object of the invention is simple with t without changing existing construction principles to create conductive seal that both good sealing effect as well as the protective conductor function according to DIN VDE 0100 part 540 fulfilled.  

Die Lösung der gestellten Aufgabe gelingt dadurch, daß die Dichtung zumindest teilweise von einer Metallfolie umgeben ist.The problem is solved in that the Seal at least partially surrounded by a metal foil is.

Die Position der Metallfolie bzw. des Metallbördels zwischen den zu verbindenden Bauteilen ist beliebig. Hinsichtlich des Querschnitts und der Leitfähigkeit der verwendeten Materiali­ en ist die DIN VDE 0100 Teil 540 zu beachten. Sowohl als Me­ tallfolie als auch als Dichtungsmaterial, kann erprobtes und bewährtes Standardmaterial verwendet werden.The position of the metal foil or the metal flange between the components to be connected is arbitrary. Regarding the Cross-section and the conductivity of the materials used DIN VDE 0100 part 540 must be observed. Both as me tall film as well as a sealing material, can be tried and tested proven standard material can be used.

Diese Maßnahmen erfordern keine Veränderung an einer beste­ henden Konstruktion, da die Form und der Querschnitt der Dichtung beliebig gestaltet sein kann. Durch dieses Prinzip, das sich auch für dünne Flachdichtungen eignet, werden die Vorgaben nach DIN VDE 0100 Teil 540 eingehalten. Die die Dichtung umgebende Metallfolie verstärkt das Dichtungsmateri­ al und trägt damit auch zur Montageerleichterung bei.These measures do not require any change to the best construction because the shape and cross section of the Seal can be designed as desired. By this principle, that is also suitable for thin gaskets, the Specifications according to DIN VDE 0100 part 540 are observed. The the Metal foil surrounding the seal reinforces the sealing material al and thus also makes installation easier.

Eine weitere Montageerleichterung wird durch die einseitig selbstklebende Metallfolie erreicht.A further ease of assembly is provided by the one-sided self-adhesive metal foil reached.

Ein Ausführungsbeispiel wird anhand einer schematisch darge­ stellten Zeichnung näher erläutert. Die Zeichnung zeigt:An embodiment is shown schematically using a Darge provided drawing explained in more detail. The drawing shows:

Zwei metallische Bauteile 1 und 2, die über eine Flachdich­ tung 3, die mit einer Metallfolie 4 umbördelt ist, kontak­ tiert sind. Die Kontaktierung dieser Bauteile 1 und 2 erfolgt über die beiden den jeweiligen Bauteilen 1 und 2 zugewandten Flächen 5 und 6 der Metallfolie 4. Die Metallfolie 4 über­ nimmt somit die Schutzleiterfunktion.Two metallic components 1 and 2 , the device via a Flachdich 3 , which is flanged with a metal foil 4 , are in contact. These components 1 and 2 are contacted via the two surfaces 5 and 6 of the metal foil 4 facing the respective components 1 and 2 . The metal foil 4 thus takes over the protective conductor function.
