Description
Anordnung zum Abdichten von Fugen an Abschirmungen gegen elektromagnetische Wellen Es ist eine Anordnung zur Abdichtung von Fugen an Abschirmungen gegen elektromagnetische Wellen mittels Doppelkontaktfederblechen vorgeschlagen worden, bei der zur Vergrößerung des Federweges der Bleche diese an der Unterlage beweglich, und zwar in Richtung des Federweges um ein bestimmtes Stück verschiebbar angebracht sind. Eine Ausführungsform nach diesem Vorschlag sieht vor, daß die Doppelkontaktfederbleche mittels Schrauben, bei denen zwischen Gewindeteil und Kopf ein gewindeloser Schaft vorgesehen ist, an der Unterlage angebracht sind. Die Doppelkontaktfederbleche haben z. B. M-förmigen oder S- (bzw. Z-) förmigen Querschnitt.Arrangement for sealing joints on shields against electromagnetic Waves It is an arrangement for sealing joints on shields against electromagnetic Waves by means of double contact spring plates have been proposed in order to enlarge of the spring deflection of the sheets, they can be moved on the base, in the direction of of the spring deflection are attached to be displaceable by a certain amount. One embodiment according to this proposal provides that the double contact spring plates by means of screws, where a threadless shaft is provided between the threaded part and the head, are attached to the base. The double contact spring plates have z. B. M-shaped or S- (or Z-) shaped cross-section.
Zur Verbesserung dieser vorgeschlagenen Anordnung mit beweglich angebrachten Kontaktfedern ist @veiterhin vorgeschlagen worden, mehrere Federbleche gegeneinander versetzt aufeinanderzulegen. Dieser Vorschlag ist aber auch dann anwendbar, wenn die Federbleche an den Unterlagen fest angebracht sind.To improve this proposed arrangement with movably attached Contact springs has been suggested @veiterhin, several spring sheets against each other stacked on top of each other. However, this suggestion is also applicable if the spring plates are firmly attached to the documents.
Die erfindungsgemäße Anordnung zum Abdichten von Fugen an Abschirmungen gegen elektromagnetische Wellen ist demgegenüber dadurch gekennzeichnet, daß an einer Unterlage mehrere Doppelkontaktfederbleche mit S- bzw. Z-förmigem Querschnitt fest angebracht sind und daß mehrere Federbleche dieser Art quer und längs gegeneinander versetzt aufeinanderliegen.The arrangement according to the invention for sealing joints on shields against electromagnetic waves is characterized in that on several double contact spring sheets with S- or Z-shaped cross-section on a base are firmly attached and that several spring plates of this type transversely and longitudinally against each other are offset on top of each other.
Die erfindungsgemäß gegeneinander versetzten Federbleche bilden zwischen dem abzuschirmnenden Raum und dem Raum, in dem sich die störenden elektromagnetischen Wellen befinden, vier Hohlräume, in denen sich die Wellen fangen können. Überdies bilden sie ,eine vierfache galvanische Verbindung zwischen den Schirmteilen, die sie überbrücken. Die Längsversetzung der Federbleche hat zur Folge, daß Stoßstellen zwischen den Blechen abgedeckt werden.According to the invention, the spring plates offset from one another form between the room to be shielded and the room in which the disturbing electromagnetic Waves are located, four cavities in which the waves can catch. Besides they form a fourfold galvanic connection between the screen parts, the they bridge. The longitudinal displacement of the spring steel sheets has the consequence that joints be covered between the sheets.
Es sind Doppelkontaktfederbleche zur Abschirmung verwendet worden, die zwischen dem Innen- und Außenraum höchstens zwei Hohlräume bilden und einen höchstens dreifachen galvanischen Kontakt zwischen den abzuschirmenden Teilen herstellen. Aus diesem Stand der Technik war nicht ersichtlich, daß man durch einfaches Ineinanderfügen von S- bzw. Z-förmigen Abschirmblechen vier Hohlräume erzeugen kann, ohne daß hierdurch ein erheblicher technischer Aufwand erforderlich ist. Dies lehrt erst die Erfindung.Double contact spring plates have been used for shielding, which form at most two cavities and one between the inner and outer space Establish a maximum of triple galvanic contact between the parts to be shielded. From this prior art it was not evident that you can simply fit together of S- or Z-shaped shielding plates can generate four cavities without this a considerable technical effort is required. This is what the invention teaches us.
Ebenfalls ist aus dem Stand der Technik nicht ersichtlich, wie man vorzugehen hat, wenn man mit ihren Stirnseiten aneinanderstoßende Federbleche ver-%venden muß. um längere Schlitze abzudichten. Dies gelingt nach der Erfindung durch die Längsversetzung mehrerer ineinandergefügter Federbleche.It is also not apparent from the prior art how to what to do if you use spring plates butting against one another with their end faces got to. to seal longer slots. This is achieved according to the invention by the Longitudinal displacement of several spring plates fitted one inside the other.
Es ist weiterhin zwar bekannt, einen Transformator in ein mehrfach abschirmendes Gehäuse einzubringen, dessen Wände sich an den Gehäusekanten überlappen. Durch diese Überlappung wird aber allein eine feste galvanische Verbindung zwischen den Randteilen erzielt. Es wird nicht die Anzahl der Hohlräume vergrößert, wie bei der erfindungsgemäßen Abschirmung.Although it is still known to convert a transformer into a multiple bring in a shielding housing, the walls of which overlap at the edges of the housing. This overlap alone creates a solid galvanic connection between achieved the edge parts. It does not increase the number of cavities as in the shield according to the invention.
In einer Ausbildung der Erfindung werden die, aufeinanderliegenden Federbleche miteinander verbunden. Dies kann mittels Schrauben, Nieten, Stiften, Löten, Schweißen od. dgl. geschehen.In one embodiment of the invention, the superposed Spring plates connected to each other. This can be done using screws, rivets, pins, Soldering, welding or the like. Done.
Die Figur zeigt in Längsrichtung aneinandergesetzte und aufeinanderliegende Federbleche. An die aufeinanderliegenden Federbleche 11 und 12 stoßen die Federbleche 13 und 14 an, wodurch Stoßkanten 15 und 16 entstehen. Diese Stoßkanten sind nun jeweils durch das darauf liegende Federblech überdeckt; so ist die Stoßfuge 15 zwischen den Federblechen 11 und 13 durch das Federblech 14 und die Stoßfuge 16 zwischen den Federblechen 12 und 14 durch das Federblech 11 überdeckt.The figure shows juxtaposed and superposed in the longitudinal direction Spring plates. The spring steel sheets abut against the spring steel sheets 11 and 12 lying on top of one another 13 and 14, creating abutting edges 15 and 16. These abutting edges are now each covered by the spring plate lying on it; so the butt joint 15 is between the spring plates 11 and 13 through the spring plate 14 and the butt joint 16 between the spring plates 12 and 14 covered by the spring plate 11.
