Description

Verfahren zur Herstellung magnetisch stabiler Kerne für Induktionsspulen In dem Patent 472 403 ist eine Anordnung zur Erzielung eines magnetisch stabilen Kernes für Induktionsspulen beschrieben, die darin besteht, daß der Kern außer in Richtung des magnetischen Feldes nur in einer zum Felde senkrechten Richtung unterteilt ist. Bei den dort erwähnten Ausführungsformen der Kerne, die im besonderen aus Drahtstücken hergestellt sind, sind letztere so angeordnet, daß die vorerwähnte Bedingung erfüllt ist.Process for the production of magnetically stable cores for induction coils In the patent 472,403 there is an arrangement for achieving a magnetically stable Core for induction coils described, which consists in the fact that the core except in Direction of the magnetic field divided only in a direction perpendicular to the field is. In the embodiments of the cores mentioned there, which in particular consist of pieces of wire are made, the latter are arranged so that the aforementioned condition is satisfied is.

Gemäß der Erfindung wird die Bedingung, daß der Kern-außer in Richtung des magnetischen Feldes nur in einer zum Felde senkrechten Richtung unterteilt sein soll, dadurch erfüllt, daß zu seiner Herstellung ein Metallband verwendet wird, welches mit Einschnitten senkrecht zum Bandrand versehen ist. Ein Kern, der aus glattem Metallband gewickelt ist, kat keine Unterteilung in der Feldrichtung, sondern nur eine Unterteilung senkrecht zur Feldrichtung. Die erforderliche Unterteilung in der Feldrichtung wird erfindung§gernäß dadurch erzielt, daß das Band senkrecht oder annähernd senkrecht zur Feldrichtung mit Einschnitten oder Schlitzen oder mit beiden derart versehen ist, daß dadurch der Zusammenhang des Bandes nicht aufgehoben wird.According to the invention, the condition is that the core-except in the direction of the magnetic field can only be subdivided in a direction perpendicular to the field should, fulfilled in that a metal band is used for its production, which is provided with incisions perpendicular to the edge of the tape. A core that consists of is wound on smooth metal tape, there is no subdivision in the field direction, but rather only one subdivision perpendicular to the field direction. The required subdivision in the field direction is achieved according to the invention in that the tape is perpendicular or approximately perpendicular to the field direction with incisions or slits or with both is provided in such a way that the connection of the band is not thereby broken will.

In der Zeichnung ist ein derartiger Kern dargestellt. Abb. i zeigt ihn im Schnitt, Abb. 2 in Aufsicht, Abb. 3 in Ansicht. Die Stärke des Bandes ist in den Abbildungen zur besseren Kenntlichmachung der Einschnitte stärker gewählt, als es der Wirklichkeit entspricht.Such a core is shown in the drawing. Fig.i shows him in section, Fig. 2 in plan, Fig. 3 in view. The strength of the band is Chosen more strongly in the illustrations for better identification of the incisions, than it corresponds to reality.

Das Band kann auf verschiedene Weise eingeschnitten sein, und zwar von beiden Seiten und an beliebigen Stellen in Mitte. Nach der Zeichnung sind die Einschnitte so gewählt, daß sie an beiden Bandrändern sich gegenüberstehen, und daß zwischen je zwei Randeinschnitten das Band noch- einmal in der Mitte geschlitzt ist. Durch derartige Einschnitte in das Band wird der aus einem Band gewickelte Kern in der Feldrichtung unterteilt.The tape can be cut in a number of ways, namely from both sides and anywhere in the middle. According to the drawing are the Incisions chosen so that they face each other on both edges of the tape, and that between every two edge incisions the tape slit again in the middle is. The tape is wound from a tape through such incisions in the tape Core divided in the field direction.

In den Abbildungen sind die Randschnitte mit a und a,, die Mittelschnitte mit b bezeichnet.In the figures, the edge cuts are designated with a and a, the middle cuts with b .

Die Einschnitte und Schlitze werden zur Erzielung einer vollständigen Unterteilung des Kernes in der Feldrichtung zweckmäßig so gewählt, daß an keiner Stelle des Bandes in seiner Längsrichtung ein längerer ungeschnittener Streifen stehenbleibt. Dies wird z. B. dadurch erreicht, daß je drei benachbarte Schlitze sich mindestens über die ganze Bandbreite erstrecken.The incisions and slots are used to achieve a complete Subdivision of the core in the field direction expediently chosen so that at none Place the length of the tape in a long, uncut strip stop. This is z. B. achieved in that three adjacent slots extend at least over the entire bandwidth.
