Description

liatallischer Abschirmkasten für elektrische Geräte jVechselstromgeräte müssen häufig abgeschirmt werden und werden zu diesem Zwecke gewöhnlich in einen Metallkasten eingeschlossen, der normalerweise mit einem abnehmbaren Deckel versehen sein muß. Dieser abnehmbare Deckel hat häufig keinen guten Kontakt, welcher -Nachteil erfindungsgemäß dadurch beseitigt werden soll, daß der Deckel unter Zwischenschaltung nachgiebiger Flansche o. dgl. aufgeschraubt ist. Diese nachgiebigen Flansche werden dabei zweckmäßig unterteilt, um einen .überall gleichmäßigen Kontakt zu sichern.Liatallic shielding box for electrical devices jAC devices often have to be shielded and are usually integrated into one for this purpose Metal box included, usually with a removable lid have to be. This removable cover often does not make good contact, which is a disadvantage according to the invention is to be eliminated in that the cover is interposed Resilient flanges or the like. Is screwed on. These compliant flanges will appropriately subdivided in order to ensure uniform contact everywhere.

Die Erfindung ist auf der Zeichnung in drei Figuren dargestellt.The invention is shown in the drawing in three figures.

Fig. i zeigt einen Teil des Metallkastens nebst Deckel im Schnitt.Fig. I shows part of the metal box together with the lid in section.

Fig.2 zeigt einen Deckel von der Innenseite.Fig.2 shows a cover from the inside.

Fig.3 zeigt einen ganzen Kasten mit Deckel perspektivisch. Der Metallkasten 2 ist mit einer Öffnung 4 versehen, die durch einen Deckel 6 abgeschlossen ist, und zwar unter Zwischenschaltung eines elastischen Flansches 8, der an dem Deckel 6 unter Vermittlung eines Rahmens io mittels Schrauben i2 befestigt ist. Dieser elastische Flansch ist, wie Fig. 2 erkennen läßt, durch Schlitze 14 unterteilt, so daß auf dem ganzen Umfang ein sicherer Kontakt gewährleistet wird. 1n diesem Falle braucht er nur durch wenige Flügelschrauben 16, wie sie in Fig. 3 dargestellt sind, befestigt zu werden.3 shows a whole box with a lid in perspective. The metal box 2 is provided with an opening 4 which is closed by a cover 6, with the interposition of an elastic flange 8 on the cover 6 is fastened by means of screws i2 with the intermediary of a frame io. This elastic flange is, as Fig. 2 shows, divided by slots 14, so that a secure contact is guaranteed over the entire circumference. 1n this Case he only needs a few wing screws 16, as shown in FIG are to be attached.
