Description

Der Erfindung liegt die Aufgabe zugrunde, für Hochfrequenzeisenkerne, bei denen die Herstellung eines zur abgleichenden Verstellung des Hochfrequenzeisenkernes dienenden Gewindes Schwierigkeiten bereitet, einen einfachen Abgleich ohne ein solches Gewinde zu erreichen. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Hochfrequenzeisenkern aus zwei ineinanderdrehbaren, sichelförmigen Teilkernen besteht.The invention is based on the object for high-frequency iron cores, in which the production of a for adjusting adjustment of the high-frequency iron core Serving thread causes difficulties, a simple adjustment without such Reach thread. According to the invention this object is achieved in that the The high-frequency iron core consists of two crescent-shaped part cores that can be rotated one inside the other.

In den Fig. i und 2 ist ein Ausführungsbeispiel eines solchen Hochfrequenzeisenkernes dargestellt; und zwar zeigen die Fig. i und 2 den erfindungsgemäßen Hochfrequenzeisenkern in den beiden Endstellungen der sichelförmigen Teilkerne. Der Hochfrequenzeisenkern, der beispielsweise aus Ferritwerkstoff hergestellt ist, besteht aus den beiden sichelförmigen Teilkernen i und 2. Die sichelförmigen Flächen der beiden Teilkerne sind so gekrümmt, daß beide Teilkerne in der einen Endstellung, wie sie in Fig. i dargestellt ist, infolge Herausdrehens des drehbaren Teilkerns 2 aus dem feststehenden Teilkern i praktisch einen Hohlzylinder bilden. In der anderen Endstellung, die in der Fig.2 dargestellt ist, bilden die beiden Teilkerne infolge Hineindrehens des drehbaren Teilkernes 2 in den feststehenden Teilkern i eine Sichel. Man erkennt aus den Fig. i und 2, daß die beiden Teilkerne zueinander außermittig angeordnet sind. Sie sind von einem z. B. aus Isolierstoff bestehenden, hohlzylinderförmigen Spulenträger 3 umgeben, an dessen Innenfläche der feststehende Teilkern i festgeklebt ist. Der Innenraum des Spulenträgers, soweit er nicht von den beiden Teilkernen i und 2 ausgefüllt ist, ist von einem beispielsweise ebenfalls. aus Isolierstoff bestehenden Stift 4 ausgefüllt, auf den der drehbare Teilkern 2 aufgeklebt ist. Um den drehbaren Teilkern 2 verstellen zu können, ist der Stift 4 mit einem Schlitz versehen. Um den in den Fig. i und 2 aus den, Teillternen i und 2 bestehenden Hochfrequenzeisenkern zu einer Baueinheit zusammenzufassen, können beispielsweise die überstehenden Stirnflächen des Spulenträgers 3 auf beiden Seiten, nach dem Einsetzen der Teilkerne i und 2 durch Warmverformung nach innen umgebördelt werden. Der mit .einem Schlitz versehene Stift 4 kann mit wachsähnlichen, nicht fester härtbaren Mitteln zum zügigen weichen Abgleich eingesetzt sein und nach dem Abgleich der Spule an beiden Seiten, mit Klebmitteln in. seiner Stellung vor Verdrehung geschützt werden. Auf den Spulenträger 3 ist in üblicher Weise die Spulenwicklung 5 aufgebracht. Es ergibt sich dann in der in Fig. i dargestellten Endstellung der Teilkerne i und 2 der höchste Induktivitätswert und in der in Fig. 2 dargestellten Endstellung der niedrigste Induktivitätswert.In Figs. I and 2 is an embodiment of such a high frequency iron core shown; namely, FIGS. i and 2 show the high-frequency iron core according to the invention in the two end positions of the sickle-shaped cores. The high frequency iron core, which is made of ferrite material, for example, consists of the two sickle-shaped Partial cores i and 2. The crescent-shaped surfaces of the two partial cores are so curved that that both partial cores in one end position, as shown in Fig. i, as a result of turning the rotatable partial core 2 out of the fixed partial core i practically form a hollow cylinder. In the other end position, which is shown in FIG is shown, form the two partial cores as a result of turning in the rotatable Partial core 2 in the fixed partial core i a sickle. One recognizes from the Fig. i and 2 that the two partial cores are arranged eccentrically to one another. they are from a z. B. made of insulating material, hollow cylindrical coil carrier 3 surrounded, on the inner surface of which the fixed partial core i is glued. Of the Interior of the coil former, if it is not filled by the two partial cores i and 2 is, for example, is of one as well. made of insulating material pin 4 filled in, on which the rotatable partial core 2 is glued. Around the rotating part core 2 to be able to adjust, the pin 4 is provided with a slot. To the in the Fig. I and 2 from the, partial internals i and 2 existing high-frequency iron core to one Combine structural unit, for example, the protruding end faces of the coil former 3 on both sides, after inserting the partial cores i and 2 be beaded inwards by hot deformation. The one with a slit Pen 4 can be quickly softened with wax-like, non-hardening agents Adjustment should be inserted and after adjusting the coil on both sides, with adhesives in. its position are protected from rotation. On the bobbin 3 is the coil winding 5 is applied in the usual manner. It then results in the in Fig. I shown end position of the partial cores i and 2, the highest inductance value and in the end position shown in FIG. 2, the lowest inductance value.
