Description
Es ist bekannt, für Übertrager, insbesondere für Eingangsübertrager von Verstärkern, den sogenannten UI-Schnitt zu verwenden und die Primär-und Sekundärwicklung je zur Hälfte auf die beiden Schenkel zu verteilen. Auf diese Weise -sohl erreicht werden, daß sich die Wirkungen eines äußeren Störfeldes in den beiden Hälften der Wicklungen gegenseitig aufgeben. Es hat sich aber gezeigt, daß dieser Aufbau zum ,Beispiel für Eingangsübertrager von Mikrofonverstärker nicht in jedem Falle genügt, insbesondere bei gedrängtem Aufbau des Verstärkers, weil dann das Störfeld inhomogen ist.It is known for transformers, especially for input transformers of amplifiers to use the so-called UI cut and the primary and secondary winding to distribute halfway between the two legs. In this way -sole reached that the effects of an external interference field in the two halves of the Give up windings on each other. But it has been shown that this structure to , Example for input transformer of microphone amplifier is not sufficient in every case, especially if the amplifier is compact, because the interference field is then inhomogeneous is.
Die Erfindung beseitigt diesen Nachbeil bei dem oben beschriebenen Übertrager dadurch, daß wenigstens einer der beiden Schenkel mit einem zusätzlichen, verschiebbaren Blechaus ferromagnetischem Werkstoff zum Abgleichen der Störspannungen versehen ist.The invention overcomes this disadvantage with that described above Transmitter in that at least one of the two legs with an additional, Slidable sheet metal made of ferromagnetic material for balancing the interference voltages is provided.
Die Abbildungen zeigen Ausführungsbeispiele der Erfindung. In Abb. i ist das Störfeld durch schräg verlaufende Linien e mit Pfeilen dargestellt. Auf ,den Schenkeln k und m des Kernes( sind sowohl die Primärwicklung g als auch die Sekundärwicklung h des Übertragers je zur Hälfte aufgebracht. Ein Abgleichblech n wird erfindungsgemäß zwischen den Schenkel k und die Wicklung eingeschoben. Ein gleiches Abgleichblech kann für den Schenkel na vorgesehen werden.The figures show exemplary embodiments of the invention. In Fig. I the interference field is shown by oblique lines e with arrows. On the legs k and m of the core ( both the primary winding g and the secondary winding h of the transformer are applied in half. According to the invention, a leveling plate n is inserted between the leg k and the winding will.
Ein Ausführungsbeispiel, das eine zweckmäßige Ausbildung eines solchen Übertragers zeigt, :ist in Abb. 2 dargestellt. Dias Blechpaket q jwird nicht in der bisher üblichen Weise durch eine Verschraubung zusammengehalten, sondern durch eine Lasche o, die unter Zwischenfügung eines Isolierstoffes s das Blechpaket umspannt. Die beiden Enden der Lasche greifen in eine Isolierplatte p ein, auf der gleichzeitig die Lötösen für die Übertrageranschlüsse angebracht sind. @Die Befestigung des Übertragers erfolgt mit Hilfe der Laschen r. Es sind zwei Abgleichbleche n vorgesehen.An embodiment that a practical training of such Transformer shows: is shown in Fig. 2. The laminated core q j is not in held together by a screw connection in the usual way, but rather by a tab o, which spans the laminated core with the interposition of an insulating material s. The two ends of the flap engage in an insulating plate p, on which at the same time the soldering lugs for the transformer connections are attached. @The attachment of the transformer takes place with the help of the tabs r. Two leveling plates are provided.
