Description
Toroidspule Zur Herstellung von Toroidspulen wird gewöhnlich aus einem genügend starken Draht eine freitragende zylindrische Spule gewickelt und diese dann zu einem Ring gebogen.Toroidal coil For the manufacture of toroidal coils is usually from a sufficiently strong wire wound a cantilevered cylindrical coil and this then bent into a ring.
Da diese Herstellungsmethode die Verwendung eines ziemlich steifen Drahtes bedingt, so macht sie den Gebrauch der Hochfrequenzlitze und auch die Herstellung der Spulen für lange Wellen unmöglich. Ferner hat diese Methode den Nachteil, daß sie eine Massenherstellung von Spulen mit absolut gleichen elektrischen Daten, wie diese beim Einknopfabstimmen von mehreren Stufen unerläßlich sind, nicht ermöglicht. Außerdem haben die freitragend gewickelten Spulen eine verhältnismäßig große Eigenkapazität, weil bei den hauptsächlich angewandten Methoden der freitragenden Wicklung am inneren Ringumfange, mehrere Windungen übereinanderliegen.Because this manufacturing method uses a fairly stiff Due to the wire, it makes the use of the high-frequency stranded wire and also the manufacture of the coils for long waves impossible. Furthermore, this method has the disadvantage that they mass-produce coils with absolutely the same electrical data as these are indispensable for one-button tuning of several levels, is not made possible. In addition, the self-supporting wound coils have a relatively large self-capacitance, because in the mainly used methods of self-supporting winding on the inside Circumference of the ring, several turns on top of each other.
Zur Vermeidung dieser Nachteile hat man auch versucht Ringspulen derart herzustellen, daß man eine größere Anzahl auf Ringteile gewickelter Teilspulen im Kreise anordnete und sie hintereinander schaltete. Diese Herstellungsmethode ist aber so umständlich und kostspielig, daß sie sich kaum Eingang in die Praxis verschafft hat.To avoid these disadvantages, attempts have also been made to use toroidal coils of this type to produce that a larger number of coil sections wound on ring parts in the Arranged circles and switched them one after the other. This manufacturing method is but so cumbersome and expensive that it can hardly be used in practice Has.
Die vorliegende Erfindung bezieht sich nun auf eine auf einen Tragkörper gewickelte Toroidspule, deren Herstellung aber wesentlich einfacher ist, als die oben beschriebene.The present invention now relates to a support body wound toroidal coil, which is much easier to manufacture than described above.
Eine Ausführungsform der Erfindung ist durch die Abb. i und 2 veranschaulicht. Wie aus der Abb. 2 ersichtlich, sind eine größere Anzahl kleiner zylindrischer Tragkörper a aneinandergereiht und durch ein in die Tragkörper geklebtes Band b, welches parallel der Spulenachse läuft, zusammengehalten, so daß die Teilspulenkörper sowohl einen langen zylindrischen Tragkörper bilden (Abb.2), wie auch durch Biegen in eine kreisförmig geordnete Lage gebracht werden können (Abb. i).An embodiment of the invention is illustrated by FIGS. As can be seen from Fig. 2, there are a large number of small cylindrical supporting bodies a strung together and by a tape b glued into the support body, which is parallel the coil axis runs, held together, so that the part of the coil form both a long cylindrical support body form (Fig.2), as well as by bending into a circular can be brought into an orderly position (Fig. i).
Ein in dieser Weise zusammengehaltener Satz von Tragkörpern kann genau wie eine zylindrische Spule auf einer gewöhnlichen Wickelmaschine durchlaufend bewickelt werden, wobei nur darauf geachtet werden muß, daß die Drahtübergänge von einem Tragkörper auf den nächstfolgenden gerade über das zusammenhaltende Band erfolgt (was übrigens von selbst geschieht, wenn mit dem Wickeln gerade am Band angefangen worden ist).A set of supporting bodies held together in this way can precisely like a cylindrical bobbin wound continuously on an ordinary winding machine Be careful only to ensure that the wire transitions from a support body on the next following straight over the cohesive tape (which, by the way, happens automatically when winding has just started on the tape).
Wenn das Wickeln des ganzen Spulensatzes fertig ist, wird dieser zu einem Kreise gebogen und dem jeweiligen Zweck entsprechend, mit einer geeigneten Schutz- und Anschlußvorrichtung versehen. (In Abb. i ist Einfachheit halber nur ein Tragkörper, und zwar im Schnitt als bewickelt dargestellt.) In der Abb. g ist die Herstellungsweise einer anderen Ausführungsform des Tragkörpersatzes dargestellt. Bei dieser wird ein langer zylindrischer Körper so geschnitten, daß die entstehenden einzelnen Tragkörper nicht vollständig von der Rolle abgetrennt, sondern durch ein schmales, ganz bleibendes Band c zusammengehalten werden.When the winding of the whole set of bobbins is finished, this one turns to Curved into a circle and according to the respective purpose, with a suitable one Provide protection and connection device. (In Fig. I is for simplicity only a support body, shown in section as wound.) In Fig. g is the production method of another embodiment of the support body set is shown. In this case, a long cylindrical body is cut so that the resulting individual support body not completely separated from the role, but by a narrow, completely permanent band c are held together.
Nach vorliegender Methode können auch Hochfrequenztransformatoren sehr einfach hergestellt werden. Dabei wird die Sekundärseite genau wie beschrieben auf einen Tragkörpersatz gewickelt. Die Primärseite wird, da sie aus verhältnismäßig wenigen Windungen zu bestehen braucht, aus steifem Draht als freitragende Spirale ausgeführt. Sie wird dann in das Innere der fertig gewickelten Sekundärspule eingeführt und mit dieser zusammen zum Ring gebogen.According to the present method, high-frequency transformers can also be used can be made very easily. The secondary side is exactly as described wound on a support body set. The primary side is, as it is made out of proportion needs to consist of a few turns, made of stiff wire as a self-supporting spiral executed. It is then inserted into the interior of the fully wound secondary coil and bent together with this to form a ring.
