Material zum Isolieren, Abschirmen und Einschließen von elektrischen Leitungen, Teilen und Gehäusen,Material for insulating, shielding and enclosing electrical lines, parts and housings,

Die Erfindung "bezieht sich auf ein Material zum Isolieren, Abschirmen und EinschlieBen von elektrischen Leitungen, Teilen und Gehäusen, insbesondere zum Schutz gegen den Einfluß von Hochfrequenzen und äußeren magnetischen Feldern,,The invention "relates to a material for insulating, Shielding and enclosing electrical lines and parts and housings, especially for protection against the influence of high frequencies and external magnetic fields,

Es ist bereits ein elektrisches Isolationsmaterial bekannt geworden, das aus einem relativ dünnen, festen GummieiernentAn electrical insulation material has already become known, which consists of a relatively thin, solid rubber core

409851/1049409851/1049

"besteht, auf das ein Kupferblatt aufgebracht ist."consists on which a copper sheet is applied.

Dieses Isolationsmaterial weist jedoch wesentlich Nachteile auf, die sich daraus ergeben, dass es bleibende Verformungen erfährt, wenn es zwischen zwei zu verbindende Elemente angebracht wird, beispielsweise zwischen dem Rand eines elektronischen Gehäuses und seinem Deckel. Dementsprechend ist nach mehreren Betätigungen eines solchen Deckels die elektrische Isolierung nicht mehr gesichert, da die ständigen Verformungen sich in ϊοπη von Unregelmässigkeiten an der Oberfläche des Belages auswirken.However, this insulation material has significant disadvantages, which result from the fact that it is permanently deformed learns when it is placed between two elements to be connected, for example between the edge of an electronic Housing and its cover. Accordingly, after several actuations of such a lid, the electrical Insulation no longer secured, as the constant deformations result in ϊοπη of irregularities on the surface of the covering.

Hauptaufgabe der Erfindung ist die Beseitigung dieser Nachteile. Dementsprechend zielt sie auf ein Material zum Isolieren, Abschirmen und Einschließen von elektrischen Leitungen, Teilen und Gehäusen ab, das dadurch gekennzeichnet ist, dass es aus einem elastisch verformbaren, mindestens auf einer der flächen mit einem metallischen Geflecht überzogenen Grundstoff besteht.The main object of the invention is to eliminate these disadvantages. Accordingly, it aims at a material for insulating, shielding and enclosing electrical lines, Parts and housings from, which is characterized in that it consists of an elastically deformable, at least on one of the surfaces covered with a metallic mesh consists.

Nach einem weiteren Erfindungsmerkmal wird als Grundstoff ein Schaumstoff mit hoher Zusammendrückfähigkeit verwendet.According to a further feature of the invention, a foam with high compressibility is used as the base material.

Nach einem dritten Erfindungsmerkmal besteht das Geflecht aus ausgewalztem ( "deploye") MetalleAccording to a third feature of the invention, the mesh consists of rolled out ("deploye") metals

Die Erfindung bezieht sich auch auf die mit dem erfindungsgemässen Material ausgestatteten Gehäuse.The invention also relates to the with the inventive Housing equipped with material.

Er-findungsgemäss wurde davon ausgegangen, dass zur Erreichung einer genügend wirksamen elektrischen Isolierung,auch nach einer relativ langen Benutzungsdauer gewährleistet sein muss, dass das Metallelement, das ah der Oberfläche mindestens eine der Flächen des elastisch verformbaren Grundstoffes angeordnet ist, sich in nicht bleibender v'veise strecken kann, so dass wenn senkrechte Verformungen zur Ebene auftreten, dieses Metallelement von selbst in die ursprüngliche Lage zurückkehrt und so neuerlich bei weiteren Benutzungen einen fast kontinuierlichen elektrischen, befriedigenden Kontakt mit dem Gegenstück herstellt.According to the invention it was assumed that in order to achieve a sufficiently effective electrical insulation, even after a relatively long period of use must be guaranteed that the metal element ah the surface at least one the surfaces of the elastically deformable base material is arranged, can stretch in non-permanent v'veise, so that if deformations perpendicular to the plane occur, this metal element will automatically return to its original position and so again an almost continuous electrical, satisfactory contact with further uses the counterpart.

Entsprechend der Erfindung wurde entdeckt, dass sich ein solches Ergebnis dann erzielen lässt, wenn als Abdeckmaterial ein metallisches Geflecht Verwendung findet, dessen verschiedene Maschen sich verformen lassen, um eine lokale Oberflächenstreckung an dem Punkt zu bewirken, wo das Isolationsmaterial zwischen Zw;ei elektrisch zu verbindende Teile gequetscht wird, wobei die genannten Maschen dann ihre ursprünglichen Formen und Dimensionen sofort wieder einnehmen, wenn der Druck auf das Material aufhörteAccording to the invention, it has been discovered that such a result can be achieved if a metallic mesh is used as the cover material, the various meshes of which can be deformed in order to bring about a local surface extension at the point where the insulation material between Zw ; ei parts to be electrically connected are squeezed, the said meshes then immediately resuming their original shape and dimensions when the pressure on the material ceases

Um ganz sicher zu vermeiden, dass bleibende Verformungen am Metallgeflecht auftreten, wurde entdeckt, dass der elastischIn order to be sure to avoid permanent deformations on the metal mesh, it was discovered that the elastic

verformbare Grundstoff, einen hohen Grad an Zusammendrückfähigkeit aufweisen muss. Diese Bedingung erfüllt ein Zellenmaterial z.B. ein 'Schaumstoff hoher Zusammendrückfähigkeit und grosser Elastizität,auf dessen einer Fläche durch Aufkleben entweder durchgehend oder örtlich ein Metallgeflecht aufgebracht ist.deformable base material, a high degree of compressibility must have. A cell material, e.g. a high compressibility foam, fulfills this requirement and great elasticity, on one surface of which a metal mesh either continuously or locally by gluing is upset.

Diese Kombination des streckbaren Metallgeflechts und des öcnaumstoffes, der leicht in einer zur Richtung der Streckung des Metallgeflechts senkrechten Richtung zusammengedrückt werden kann, bewirkt, dass bei einer lokalen Kompression des Isolationsmaterials das Metallgeflecht den Schaumstoff auf einer sehr viel grösseren Fläche zusammendrückt als derjenigen Fläche, die den Druck auf das Metallgeflecht ausübt. Es wird also mit Sicherheit auf diese Weise vermieden, dass dauerhafte Verformungen am Metallgeflecht auftreten, wobei die Rückkehr zu den ursprünglichen Abmessungen des Metallgeflechts noch durch die Entspannungskraft des zur Wiedereinnahme der ursprünglichen Lage tendierenden Schaumstoffes begünstigt wird.This combination of the stretchable metal mesh and the foam, which can be easily moved in one direction to the direction of stretching of the metal mesh can be compressed in the vertical direction, causes local compression of the Isolation material the metal mesh compresses the foam on a much larger area than that Area that exerts pressure on the metal mesh. So it will certainly avoid being permanent in this way Deformations occur on the metal braid, with the return to the original dimensions of the metal braid nor through the relaxation power of the to take back the original location tending foam is favored.

Erfindungsgemäss kann das Geflecht auf verschiedene Weise hergestellt werden, beispielsweise aus ausgewalztem ("deploye") Metall aus gewebtem oder gestricktem Metalldraht, wobei in Kombination durch Stricken oder v/eben ein Metalldraht und ein synthetischer Draht verwendet werden kann, oder aber es kann das Metallgeflecht mit Hilfe eines Drahtes aus synthetischemAccording to the invention, the braid can be in various ways be made, for example from rolled out ("deploye") Metal made of woven or knitted metal wire, whereby in combination by knitting or v / just a metal wire and a Synthetic wire can be used, or it can be the metal braid using a synthetic wire

Vorzugsweise wird das Isolationsmaterial, das auf einer seiner Flächen ein Metallgeflecht aufweist, auf seiner anderen Fläche mit einer direkt aufgebrachten Klebsubstanz versehen, die entweder auf dem Schaumstoff, oder auf einer Plastikfolie aufliegt. Es wird hierdurch ermöglicht, dass das Material durch Kleben auf der Innenfläche des Deckels eines elektronischen Gehäuses schnell befestigt werden kann.The insulation material, which has a metal mesh on one of its surfaces, is preferably used on its other surface provided with a directly applied adhesive substance, either on the foam or on a plastic sheet rests. This enables the material to be glued onto the inner surface of the lid of an electronic Housing can be attached quickly.
