An elastomer seal has a conducting coating. Preferred Features: The coating is metallic, thin and applied by a vacuum technique. The seal is in the form of a ring.

Description

Gegenstand der Anmeldung, AnwendungsbereicheSubject of registration, areas of application

Dichtungen finden vielfältige Anwendungen in den verschiedensten Bereichen. Sie werden zum Abdichten von Fluiden und Gasen gegen Über- und Unterdruck (Vaku­ um) sowie bei gleichem Druck als Trennung, z. B. zum Spritzwasserschutz verwen­ det. Weiterhin finden elektrische Dichtungen zur elektromagnetischen Abschirmung (EMV) Anwendung.Seals are used in a wide variety of areas. she are used to seal fluids and gases against excess and negative pressure (vacuum um) and at the same pressure as a separation, e.g. B. use for splash protection det. There are also electrical seals for electromagnetic shielding (EMC) application.

Die vorliegende Erfindung beschreibt eine Dichtung, bei der die Vorteile verschied­ ner existierender Konzepte in einem einzigen Element vereinigt sind.The present invention describes a seal in which the advantages differ existing concepts are combined in a single element.

Stand der TechnikState of the art

Eine Vielzahl von Dichtungselementen wird aus elastomeren Materialien wie Silikon, Gummi, Nitril oder Viton gefertigt. Diese weisen gute Dichteigenschaften für Fluide und Gase auf und sind realtiv elastisch, was eine kostengünstige Verwendung mit nicht zu großen Anforderungen an die Planarität der Dichtflächen ermöglicht. Diese Dichtungen sind jedoch, da nicht leitend, nicht für EMV-Anwendungen geeignet. A variety of sealing elements are made of elastomeric materials such as silicone, Made of rubber, nitrile or Viton. These have good sealing properties for fluids and gases on and are realtively elastic, which is inexpensive to use with does not allow too great demands on the planarity of the sealing surfaces. This However, because they are not conductive, seals are not suitable for EMC applications.  

Für elektromagnetische Abschirmungen werden Dichtungen aus leitenden Materia­ lien verwendet. Hier gibt es Metallgestricke, Kontaktfederstreifen, und verschiedene hybride Aufbauten. Diese sind jedoch alle nicht dicht gegen Fluide und Gase.Seals made of conductive material are used for electromagnetic shielding lien used. There are metal knits, contact spring strips, and various hybrid superstructures. However, these are not all tight against fluids and gases.

Aus diesem Grund müssen in vielen Fällen zwei Dichtungen nebeneinander vorge­ sehen werden. Eine EMV-Dichtung und eine Fluid- bzw. Gasdichtung. Beispiele sind Spritzwasser- und EMV- geschützte Gehäuse oder Vakuumkammern.For this reason, in many cases, two seals must be pre-arranged side by side will see. An EMC seal and a fluid or gas seal. Examples are splash-proof and EMC-protected housings or vacuum chambers.

Metalldichtungen können beide Anforderungen erfüllen, stellen jedoch aufgrund ihrer geringen Elastizität hohe Anforderungen an die Planarität der Dichtflächen, was bei größeren Dichtflächen zu erheblichen Kosten führt, wie zum Beispiel in der Ultrahochvakuumtechnik.Metal seals can meet both requirements, but due to their low elasticity places high demands on the planarity of the sealing surfaces, which leads to considerable costs for larger sealing surfaces, such as in the Ultra high vacuum technology.

Beschreibung der ErfindungDescription of the invention

Erfindungsgemäß wird diese Problematik durch eine Dichtung gelöst, die aus einem elastomeren Kern (1) mit einer leitfähigen Schicht (2) besteht. Diese Dichtung kann die beiden konventionellen Dichtungen ersetzen.According to the invention, this problem is solved by a seal consisting of an elastomeric core ( 1 ) with a conductive layer ( 2 ). This seal can replace the two conventional seals.

Als leitfähige Schicht kann eine Metallschicht verwendet werden, die mittels eines Vakuumverfahrens, wie zum Beispiel der Kathodenzerstäubung, sehr dünn aufge­ bracht wird und dadurch die Elastizität des Basismaterials nicht beeinträchtigt.A metal layer can be used as the conductive layer Vacuum processes, such as sputtering, are applied very thinly is brought and does not affect the elasticity of the base material.

Diese Metallschicht kann bei einigen Anwendungen, zum Beispiel in der Vakuum­ technik, die Dichtungseigenschaften der Elastomerdichtung sogar verbessern.This metal layer can be used in some applications, for example in vacuum technology that even improve the sealing properties of the elastomer seal.

Neben einer separaten Dichtung ist es erfindungsgemäß möglich, ein dichtendes elastomeres Material (3) auf ein zu dichtendes Teil (4) aufzubringen. Daraufhin wird Dichtung und Teil in einem Arbeitsgang leitend beschichtet, wodurch zum Beispiel eine EMV-Abschirmung und eine Feuchtigkeitsdichtung wirkungsvoll und kosten­ günstig hergestellt werden kann.In addition to a separate seal, it is possible according to the invention to apply a sealing elastomeric material ( 3 ) to a part ( 4 ) to be sealed. Thereupon, the seal and the part are conductively coated in one operation, whereby, for example, an EMC shield and a moisture seal can be produced effectively and inexpensively.
