Schirragehäuse aus Ku-IIetali ■■■-,.Screen housing made of Ku-IIetali ■■■ - ,.
Es sind Schirmgehäuse aus Mu»IIetall für Übertrager oder dergleichen bekannt, die aus IIu-lietall-Blechen gewickelt sind. Derartige Gehäuse haben jedoch nur bei niedrigen Frequenzen eine ausreichende Schirmwirkung gegen elektronagnetisehe Felder. Es wurde deshalb schon vorgeschlagenf zur Erhöhung der Schirmwirkung in höheren Frequenzbereich in die gewickelten Gehäuse eine Kupferfplie mit einzuwickeln. In neuerer Zeit werden die Schirmgehäuse aus LIu-I Ie tall häufig nicht mehr gewickelt, sondern tiefgezogen. Zur Er» '0 höhung der Schirmwirkung solcher Gehäuse wurde ein zusätzliches Kupfergehäuse um das Gehäuse aus EIu-Metall ange- There are known screen housings made of metal for transformers or the like, which are wound from metal sheets. However, such housings only have a sufficient shielding effect against electromagnetic fields at low frequencies. It has therefore been proposed to increase the f shielding effect in higher frequency range into the wound housing a Kupferfplie with wrap. In recent times, the shield housings made of LIu-Ie tall are often no longer wound, but deep-drawn. To increase the shielding effect of such housings, an additional copper housing was added around the housing made of EIu metal.

ordnet. Eine solche Anordnung bedingt aber einen erheblichen Aufwand» Ziel der Eeuerung ist, ein Schirmgehäuse zu schaffen., das auch bei hohen Frequenzen eine gute Schirmwirkung ausübt, das aber dennoch nur einen geringen Auf ν. and erfordert. Dieses Ziel vdrd dadurch erreicht, daß das Gehäuse aus Hu-Hetall auf der Außen- und/oder Innenseite mit einer Schicht aus gut leitenden LIetall überzogen ist. Diese gut leitende Metallschicht kann aufgalvanisiert sein. Is hat sich gezeigt, daß eine Schichtdicke von etwa 0,1 mm ausreichend stark ist.arranges. Such an arrangement, however, requires considerable effort »The aim of the renewal is a screen housing to create., which is a good one even at high frequencies Has a shielding effect, but only a minor one On ν. and requires. This goal is achieved in that the housing is made of Hu-Hetall on the outside and / or inside covered with a layer of highly conductive metal is. This highly conductive metal layer can be electroplated be. It has been shown that a layer thickness of about 0.1 mm is sufficiently thick.
In der Zeichnung ist als Ausführungsbeispiel ein SchirmgehUu.se für einen Topfkernübertrager dargestellt. Mit 1 und 2 sind die beiden Teile eines Topfkernes bezeichnet* . der die 'wicklungen3 .enthält. Die beiden Teile des Topfkernes sind in bekannter Weise mittels eines Bügels 4 und einer tasche 5, die miteinander vernietet sind, gegeneinander verspannt. Über dem Bügel 4 sitzt ein Gehäuse 6 aus.Hu-.Metall, das zur.'Verdeutlichung, unverhältnismäßig stark dargestellt ist. Auf der Innen- und Außenseite dieses Mu-IIetallschirir.es ist eine Kupferschicht von etv.a 0,1.-an Stärke aufgalvanisiert. Es hat sich gezeigt, daß ein derartiges Ge häuse dieselbe Schirmwirkung wie die bekannten Gehäuse hat.In the drawing, a screen housing is shown as an exemplary embodiment shown for a pot core transformer. With 1 and 2 the two parts of a pot core are designated * . which contains the 'windings3. The two parts of the pot core are in a known manner by means of a bracket 4 and a pocket 5, which are riveted together, against each other tense. A housing 6 made of Hu-metal is seated above the bracket 4. that for clarification, depicted disproportionately is. On the inside and outside of this Mu-IIetallschir.es is a copper layer of about 0.1.-in thickness electroplated. It has been shown that such a Ge housing has the same shielding effect as the known housing.
