Description

Bei Geräten der Nachrichtentechnik ist es bekannt, Spulen, die miteinander magnetisch verkoppelt sind, auf einem Spulenkörper neben-oder übereinander anzuordnen. In den Spulenkörper taucht ein magnetisierbarer Eisenkern ein, durch den der Kopplungsfaktor der Spulen untereinander und die Größe der Induktivitäten beeinflußt wird. Dieser Eisenkern ist für einfache Spulenanordnungen als Stiftkern ausgeführt. Für eine gewünschte Veränderung der Parameter ist der Stiftkern mit einem Gewinde versehen und in seiner Lage zu den Spulen verstellbar. Gemeinsam für die einzelnen Teilspulen ist in einem derartigen Aufbau die Frequenz der Ströme.In telecommunications equipment, it is known to arrange coils that are magnetically coupled to one another on or next to one another on a coil former. A magnetizable iron core is immersed in the coil body, which influences the coupling factor of the coils with one another and the size of the inductors. This iron core is designed as a pin core for simple coil arrangements. For a desired change of the parameters, the pin core is provided with a thread and its position relative to the coils can be adjusted. In such a construction, the frequency of the currents is common to the individual sub-coils.

Aus dem Dokument GB-A-2079065 ist eine Spulenanordnung für einen linearen Differentialübertrager bekannt, in welchem ein beweglicher Stiftkern in zwei nebeneinanderliegende Wicklungen eintaucht, die näherungsweise gleich große Windungszahlen aufweisen. Die Wicklungen sind so in Reihe geschaltet, daß ihre Magnetfelder im Stiftkern gegensinnig zueinander wirken. Bei Einkopplung einer Wechselspannung von einer dritten Wicklung kann eine Spannung an der Reihenschaltung abgenommen werden, aus der bei axialer Bewegung des Stiftkernes eine Aussage über die Lage bzw. den zurückgelegten weg des Stiftkernes abgeleitet werden kann.From document GB-A-2079065 a coil arrangement for a linear differential transformer is known in which a movable pin core is immersed in two adjacent windings which have approximately the same number of turns. The windings are connected in series so that their magnetic fields in the pin core act in opposite directions to each other. When an AC voltage is coupled in from a third winding, a voltage can be tapped at the series circuit, from which a statement about the position or the distance traveled of the pin core can be derived when the pin core moves axially.

Sollen die einzelnen Wicklungen einer Spule mit unterschiedlichen Frequenzen oder gleicher Frequenz aber für getrennte elektrische Anwendungen verwendet werden, ist dafür zu sorgen, daß die Kopplung der Spulen untereinander minimiert wird. Die Kopplung muß so gering sein, daß keine magnetische Beeinflussung untereinander erfolgt. Um eine derartige Lösung zu erreichen, ist es bekannt, einen magnetischen Eisenkern in Doppel-E-Form zu verwenden. Dabei werden die beiden E-förmigen Teile so zusammengefügt, daß sich ein Rechteck mit zwei Fensteröffnungen ergibt. Die Wicklungen sind auf den beiden außen liegenden Schenkeln angeordnet. Die magnetische Trennung wird dadurch erreicht, daß in die äußeren Schenkel des E-förmigen Eisenkerns ein Luftspalt eingeschliffen wird, während im mittleren Steg die Eisenteile direkt aufeinander liegen. Der magnetische Fluß innerhalb der einzelnen Wicklungen wird also durch den Luftspalt innerhalb der Wicklung bestimmt, während in dem beiden Spulen gemeinsamen mittleren Steg der Luftspalt so gering wie möglich gehalten wird, so daß die magnetische Verkopplung beider Spulen untereinander eine minimale Größenordnung erreicht, die einen getrennten Einsatz der beiden Spulen z. B. mit verschiedenen Frequenzen zuläßt. Um im mittleren Steg beim Zusammenfügen der Eisenteile möglichst keinen Luftspalt zu erhalten, ist diese Fläche durch besondere Arbeitsvorgänge optimal eben ausgeführt.If the individual windings of a coil with different frequencies or the same frequency are to be used for separate electrical applications, however, care must be taken to minimize the coupling of the coils to one another. The coupling must be so low that there is no magnetic interference with one another. In order to achieve such a solution, it is known to use a magnetic iron core in a double E shape. The two E-shaped parts are assembled so that a rectangle with two window openings results. The windings are arranged on the two outer legs. The magnetic separation is achieved by grinding an air gap into the outer legs of the E-shaped iron core, while the iron parts lie directly on top of each other in the central web. The magnetic flux within the individual windings is thus determined by the air gap within the winding, while the air gap is kept as small as possible in the central web common to the two coils, so that the magnetic coupling of the two coils to one another reaches a minimum order of magnitude, which is separate Use of the two coils z. B. with different frequencies. In order to ensure that there is as little air gap as possible when joining the iron parts in the middle web, this area is optimally level thanks to special work processes.

Da eine derartige Anordnung mit zwei E-förmigen Eisenteilen sehr kostenaufwendig ist, liegt der Erfindung die Aufgabe zugrunde, eine Spulenanordnung mit mehreren Wicklungen für unterschiedliche Anwendungen mit nur einem Eisenkern anzugeben.Since such an arrangement with two E-shaped iron parts is very expensive, the object of the invention is to provide a coil arrangement with several windings for different applications with only one iron core.

Diese Aufgabe wird durch die im Anspruch 1 beschriebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the invention described in claim 1. Advantageous developments of the invention are described in the subclaims.

Im Prinzip werden durch zwei in Reihe geschaltete, nebeneinander auf einem Körper angeordnete Spulen mit gleich großer Induktivität je nach Polung der Spulen zueinander beim Anlegen einer Wechselspannung in der gemeinsamen Spulenachse unterschiedlich große Magnetfelder erzeugt. Bei gleichsinniger Polung der Spulen erreicht dieses Magnetfeld einen bestimmten Wert, während bei gegensinniger Polung das resultierende Magnetfeld nicht oder kaum nachzuweisen ist. Diese Erkenntnis wird bei der Problemlösung in einer Spulenanordnung mit einem Stiftkern ausgenutzt, um Spulen für unterschiedliche Aufgaben und mit verschiedenen Frequenzen zu realisieren. Wird nämlich zwischen den nebeneinander liegenden, in Reihe geschalteten magnetisch gegensinnig gepolten Wicklungen eine dritte Wicklung angeordnet, ist diese näherungsweise frei von Feldlinien der äußeren Wicklungen und kann als gesonderte Spule eingesetzt werden. Bei unterschiedlichen Induktivitäten ist es zweckmäßig, die Spule mit der größeren Induktivität in der Mitte anzuordnen, da in diese Spule bei Verwendung eines Stiftkernes dieser voll eintaucht und keine Induktivitätsverluste wie bei den äußeren Spulen durch die gegeneinander gepolten Wicklungen entstehen. Fertigungstoleranzen können bei der Herstellung durch Verschieben des Stiftkerns ausgeglichen werden, so daß die äußeren Wicklungen exakt gleich große Induktivitäten und bei Anlegen einer Wechselspannung gleich große gegeneinander gerichtete Magnetfelder aufweisen. Die gegenpolige Schaltung der äußeren Wicklungen bedingt Induktivitätsverluste. Trotz dieser Induktivitätsverluste wird für die äußeren Wicklungen eine ausreichende Induktivität, hervorgerufen durch Streufelder, erzielt.In principle, two coils connected in series, arranged one next to the other on a body and having the same inductance, generate magnetic fields of different sizes depending on the polarity of the coils to one another when an AC voltage is applied in the common coil axis. If the coils are polarized in the same direction, this magnetic field reaches a certain value, whereas if the polarity is in opposite polarity, the resulting magnetic field is not or hardly detectable. This knowledge is used in solving problems in a coil arrangement with a pin core in order to realize coils for different tasks and with different frequencies. If a third winding is arranged between the side-by-side, series-connected magnetically polarized windings, this winding is approximately free of field lines of the outer windings and can be used as a separate coil. In the case of different inductances, it is expedient to arrange the coil with the larger inductance in the center, since when a pin core is used, this coil is fully immersed and there are no inductance losses as with the outer coils due to the mutually polarized windings. Manufacturing tolerances can be compensated for during manufacture by moving the pin core, so that the outer windings have exactly the same inductances and, when an AC voltage is applied, the same magnetic fields directed against each other. The reverse pole connection of the outer windings causes losses in inductance. Despite these losses in inductance, sufficient inductance, caused by stray fields, is achieved for the outer windings.

To better understand the invention, exemplary embodiments are explained in more detail below with reference to drawings. Show it :
  • 1 is a schematic drawing of the coil arrangement,

Die Fig. 1 zeigt eine Spulenanordnung mit drei Wicklungen 2, 3 und 4 mit den Wicklungsanschlüssen 6, 7, 8 und 9. Die Wicklungen sind nebeneinander auf einem Wickelkörper 5 angeordnet. Im Wickelkörper 5 befindet sich ein magnetisierbarer Stiftkern 1, der in seiner Lage zu den Wicklungen verstellbar ist. Die äußeren Wicklungen 2 und 4 sind derart angeordnet, daß der Stiftkern mit den Spulenaußenkanten annähernd abschließt. Sie sind so in Reihe geschaltet, daß sie magnetisch gegensinnig wirken. Die Richtung der Magnetfelder wird durch die eingezeichneten Feldlinien angedeutet. Durch den Abstand der äußeren Wicklungen 2, 4 voneinander ist trotz ihrer entgegengesetzten Polung die magnetische Wirkung des Stiftkernes so, daß noch eine ausreichende Induktivität erzielbar ist. Die Entkopplung der Wicklung 3 ist optimal, wenn der Stiftkern 1 so eingestellt wird, daß die Magnetfelder der äußeren Wicklungen 2, 4 gleich groß sind. Da der Stiftkern 1 in die mittlere Wicklung 3 voll eintaucht, schließen sich die Feldlinien dieser Spule in der dargestellten Weise, wobei Richtung der Feldlinien und die angelegte Frequenz wählbar sind. Die mittlere Wicklung 3 induziert in den äußeren Wicklungen Ströme, die gleich groß sind und einander durch die gegensinnige Polung auslöschen.1 shows a coil arrangement with three windings 2, 3 and 4 with the winding connections 6, 7, 8 and 9. The windings are arranged next to one another on a winding body 5. In the winding body 5 there is a magnetizable pin core 1, which is adjustable in its position relative to the windings. The outer windings 2 and 4 are arranged in such a way that the pin core approximately closes with the outer edges of the coil. They are connected in series so that they act magnetically in opposite directions. The direction of the magnetic fields is indicated by the field lines. Due to the distance of the outer windings 2, 4 from one another, despite their opposite polarity, the magnetic effect of the pin core is such that sufficient inductance can still be achieved. The decoupling of the winding 3 is optimal if the pin core 1 is set so that the magnetic fields of the outer windings 2, 4 are of the same size. Since the pin core 1 is fully immersed in the middle winding 3, the field lines of this coil close in the manner shown, the direction of the field lines and the frequency applied being selectable. The middle winding 3 induces currents in the outer windings that are of the same size and cancel each other out by the opposite polarity.

Die Fig. 2 zeigt einen Teil einer Horizontal-Ablenkschaltung in einem Fernsehgerät mit einem Eingang 10, den Ablenkspulen 11, 12, dem linearen Einsteller 14, dem Tangenskondensator 15, der Brückenspule 16, dem Parallelkondensator 17, den Dioden 18, 19, den Rücklaufkondensatoren 20, 21, der'Ost-West-Ansteuerspule 22 und der Ost-West-Schaltung 23.Fig. 2 shows part of a horizontal deflection circuit in a television with an input 10, the deflection coils 11, 12, the linear adjuster 14, the tangent capacitor 15, the bridge coil 16, the parallel capacitor 17, the diodes 18, 19, the flyback capacitors 20, 21, the east-west drive coil 22 and the east-west circuit 23.

In einem bevorzugten Ausführungsbeispiel wird die mittlere Wicklung 3 als Ost-West-Ansteuerspule mit ca. 6 mH und die Reihenschaltung der äußeren Wicklungen 2, 4 als Brückenspule mit ca. 1,7 mH in einem Fernsehgerät eingesetzt. Es ist für eine rationelle Fertigung zweckmäßig, alle Wicklungen mit gleichem Drahtdurchmesser auszuführen. Die äußeren Wicklungen 2,4 können je nach Anschlußfolge im gleichen Wickelsinn oder auch gegensinnig zueinander gewickelt werden. Sollen unterschiedliche Drahtdurchmesser verwendet werden, ist es günstiger, die Ost-West-Ansteuerspule in den Außenkammern und die Brückenspule in der Mittelkammer anzuordnen.In a preferred embodiment, the middle winding 3 is used as an east-west control coil with approximately 6 mH and the series connection of the outer windings 2, 4 as a bridge coil with approximately 1.7 mH in a television set. For rational production, it is advisable to carry out all windings with the same wire diameter. Depending on the connection sequence, the outer windings 2, 4 can be wound in the same winding direction or in opposite directions to one another. If different wire diameters are to be used, it is more advantageous to arrange the east-west control coil in the outer chambers and the bridge coil in the middle chamber.

Die Fig. 3 zeigt einen Stiftkern 1 in einem Wickelkörper 5 mit Spulenkammern 25, 26, 27 und den Anschlußstiften 29. In diesem Ausführungsbeispiel ragt der Stiftkern 1 über die Spulenkammern 25 und 27 hinaus. Zu den Vorteilen einer Spule mit gleichem Drahtdurchmesser zählt auch eine optimale Wickeltechnik, insbesondere bei automatisch gefertigten Spulen. Deshalb werden die Spulenkammern 25 und 27 in einem Arbeitsgang bewickelt. Dies geschieht folgendermaßen :

  • Kammer 25 wird bewickelt, danach wird in Kammer 26 im gleichen Wickelsinn wie in Kammer 25 eine Übergangswindung bis Kammer 27 gewickelt, die Kammer 27 wird mit entgegengesetztem Wickelsinn wie Kammer 25 bewickelt. Dann wird in Kammer 26 im gleichen Wickelsinn wie Kammer 27 eine Übergangswindung gewickelt und herausgeführt. Zum Abschluß wird Kammer 26 mit beliebigem Wickelsinn bewickelt.
3 shows a pin core 1 in a winding body 5 with coil chambers 25, 26, 27 and the connecting pins 29. In this exemplary embodiment, the pin core 1 projects beyond the coil chambers 25 and 27. The advantages of a spool with the same wire diameter also include an optimal winding technology, especially with automatically manufactured spools. Therefore, the coil chambers 25 and 27 are wound in one operation. This is done as follows:
  • Chamber 25 is wound, then a transition turn to chamber 27 is wound in chamber 26 in the same winding direction as in chamber 25, chamber 27 is wound with the opposite winding direction as chamber 25. Then a transition turn is wound in chamber 26 in the same direction as chamber 27 and led out. Finally, chamber 26 is wound with any winding direction.

Fig. 4 zeigt einen Teil einer Vertikal-Ablenkschaltung in einem Fernsehgerät mit einer Vertikal-Integrationsspule 2, 4 und dem Ansteuerteil für eine Horizontalablenkschaltung mit einem Zeilen-Treibertransformator 3.4 shows a part of a vertical deflection circuit in a television set with a vertical integration coil 2, 4 and the drive part for a horizontal deflection circuit with a line driver transformer 3.

An den Anschluß A werden aus einem Impulsgeber Impulse für die Steuerung des Stromes in den Horizontalablenkspulen zugeführt. Sie werden im Transistor 40 verstärkt, dessen Kollektor mit einem Anschluß der Primärspule 31 des Zeilen-Treibertransformators 3 verbunden ist. Der andere Anschluß liegt an der Versorgungsspannung + Uε. Von der Sekundärspule 30 gelangen die Impulse an den Eingang des Zeilenendtransistors 43, von dessen Kollektoranschluß C die nichtdargestellten Horizontalablenkspulen und der Zeilentransformator angesteuert werden.At terminal A, pulses for controlling the current in the horizontal deflection coils are supplied from a pulse generator. They are amplified in transistor 40, the collector of which is connected to a connection of primary coil 31 of row driver transformer 3. The other connection is connected to the supply voltage + Uε. The pulses arrive from the secondary coil 30 at the input of the line end transistor 43, from whose collector connection C the horizontal deflection coils (not shown) and the line transformer are driven.

An Anschluß B werden aus einem Impulsgenerator Impulse für die Vertikalablenkung zugeführt. Thyristor 36 ist als Schalter aufzufassen, durch den die an die Reihenschaltung der Vertikalablenkspulen 40 mit Vertikal-Integrationsspule 2, 4 im Takte der Horizontalfrequenz angelegten Horizontalrücklaufimpulse aus der ebenfalls in Reihe liegenden Wicklung 39 des Zeilentransformators geschaltet werden. Durch die Vertikal-Integrationsspule 2, 4 wird der Verlauf der Vertikal-Ablenkspannung so geformt, daß auf dem Bildschirm Zeilen mit gleichem vertikalen Abstand geschrieben werden.At port B, pulses for vertical deflection are supplied from a pulse generator. Thyristor 36 is to be understood as a switch by means of which the horizontal flyback pulses applied to the series connection of the vertical deflection coils 40 with vertical integration coil 2, 4 in time with the horizontal frequency are switched from the winding 39 of the line transformer, which is also in series. The course of the vertical deflection voltage is shaped by the vertical integration coil 2, 4 in such a way that lines are written on the screen with the same vertical spacing.

Die Spulen 30, 31 und 2, 4 sind auf einem Stiftkern angeordnet, welches durch die verbindende, gestrichelte Linie für den gemeinsamen Eisenkern angedeutet wird.The coils 30, 31 and 2, 4 are arranged on a pin core, which is indicated by the connecting, dashed line for the common iron core.

Fig. 5 zeigt die Anordnung der Wicklungen für den Zeilen-Treibertransformator 3 und für die Vertikal-Integrationsspule 2, 4 nach Fig.4.FIG. 5 shows the arrangement of the windings for the row driver transformer 3 and for the vertical integration coil 2, 4 according to FIG. 4.

In einem Wickelkörper 5 mit fünf Wickelkammern ist der Eisenkern 1 in Form eines Stiftkernes etwa mittig zu den Kammern angeordnet. Die äußeren Kammern nehmen die gegensinnig zueinander gewickelten Teilspulen der Vertikal-Integrationsspule 2, 4 auf. Durch diese gegensinnige Wickelart heben sich Streufelder so weit auf, daß ein teurer Ferritbecher für Schirmungszwecke nicht benötigt wird.In a winding body 5 with five winding chambers, the iron core 1 in the form of a pin core is arranged approximately in the middle of the chambers. The outer chambers receive the partial coils of the vertical integration coil 2, 4 wound in opposite directions. With this type of opposite winding, stray fields cancel each other out to such an extent that an expensive ferrite cup is not required for shielding purposes.

Der Zeilen-Treibertransformator ist in den drei mittleren Kammern untergebracht. Die Sekundärwicklung 30 liegt als untere Wicklung nahe am Eisenkern. Die Wicklungsverteilung ist so gewählt, daß die mittlere Kammer eine größere Sekundärwindungszahl aufnimmt als die danebenliegenden Kammern aufweisen, wodurch eine optimale Feldverteilung möglich ist, so daß eine gegenseitige Beeinflussung von Zeilen-Treibertransformator und Vertikal-Integrationsspule minimiert werden kann. Wegen des größeren Drahtdurchmessers und auch wegen der hohen Ströme hat es sich als zweckmäßig erwiesen, die Sekundärspule in den unteren Wicklungslagen der drei mittleren Kammern anzuordnen. Zweckmäßigerweise wird diese mit demselben Draht gewickelt, der auch für die Vertikal-Integrationsspulen vorgesehen ist.The row driver transformer is housed in the three middle chambers. The secondary winding 30 is located as the lower winding close to the iron core. The winding distribution is chosen so that the middle chamber has a larger number of secondary turns than the adjacent chambers, which enables an optimal field distribution, so that mutual interference between the row driver transformer and the vertical integration coil can be minimized. Because of the larger wire diameter and also because of the high currents, it has proven to be expedient, the seconds Arrange därspule in the lower winding layers of the three middle chambers. It is expediently wound with the same wire that is also provided for the vertical integration coils.

Die Primärwicklung 31 ist als letzte Wicklung auf die darunterliegende Sekundärwicklung 30 aufgebracht.The primary winding 31 is applied as the last winding to the secondary winding 30 underneath.
