Description
Die Erfindung. bezieht sich auf eine abgleichbare Ringkerninduktivität zur Verwendung in Geräten der Fernmeldetechnik.The invention. refers to an adjustable toroidal core inductance for use in telecommunications equipment.
Es ist bekannt, in Geräten der Fernmeldetechnik, insbesondere in Hochfrequenzgeräten, die mit Hochfrequenzeisenspulen ausgerüstet sind, Ringkerne zu verwenden, um die Streuung solcher Spulen weitgehend herabzusetzen.It is known that in telecommunications equipment, especially in high-frequency equipment, which are equipped with high frequency iron coils to use toroidal cores to the To reduce the spread of such coils to a large extent.
Es ist auch bekannt, diese Ringkernspulen durch Ortsveränderung einzelner Kernteile abstimmbar bzw. abgleichbar zu machen.It is also known that these toroidal coils can be made by changing the location of the individual To make core parts tunable or adjustable.
Die Erfindung verwendet nun diese bekannte Vorrichtung für die Kopplungsänderung von Ringkernspulen. Zu diesem Zweck werden die zu koppelnden Spulen auf Sektoren eines Ringes aufgewickelt, der im Durchmesser einen Querbalken aus Hochfrequenzeisen enthält. Ein Teil dieses Querbalkens, etwa ein mit Gewinde versehener Abgleichstift, ist zwecks Kopplungsänderung ortsveränderlich angeordnet. Jede der Spulen kann gemäß einer Weiterbildung der Erfindung für sich abgleichbar gemacht werden.The invention now uses this known device for the coupling change of toroidal coils. For this purpose, the coils to be coupled are placed on sectors a ring wound up, the diameter of which is a crossbar made of high-frequency iron contains. Part of this crossbar, such as a threaded alignment pin, is arranged to be movable in order to change the coupling. Each of the coils can according to a further development of the invention can be adjusted for itself.
Der Querbalken kann auch seinerseits weitere mit den Spulen auf den Sektoren zu koppelnde Spulen tragen.The crossbar can in turn also be connected to the coils on the other Wear sectors to be coupled coils.
Um eine möglichst weitgehende Trennung des Induktivitätsabgleichs und der Kopplungsänderung zu erreichen, können diese Querstegspulen auf dem Quersteg ihrerseits verschiebbar sein. Der Abgleich bzw. die Kopplungsänderung findet zweckmäßig durch einen Drehkern statt, dessen Querschnitt vom Kreisprofil abweicht, jedoch einen möglicjist großen Teil des Querstegs ausfüllt.To achieve the greatest possible separation of the inductance adjustment and to achieve the coupling change, these crossbar coils can be on the crossbar in turn be movable. The adjustment or the coupling change is expedient by a rotating core, the cross-section of which deviates from the circular profile, however fills a possibly large part of the transverse web.
Das magnetisch aktive Material besteht vorzugsweise aus Werkstoffen, die der als Ferrit bezeichneten Gruppe angehören. Zur leichteren Anbringung der Wicklungen kann der Kern aus zwei oder mehreren Teilen bestehen, die erst nach Aufbringung der Wicklung zusammengesetzt werden.The magnetically active material preferably consists of materials belonging to the group known as ferrite. For easier attachment of the Windings, the core can consist of two or more parts, which only after application of the winding.
Die Zeichnung zeigt, beispielsweise schematisch eine Ausführungsform der Erfindung eines mit Quersteg versehenen Ringes mit zwei miteinander zu koppelnden Spulen und den zugeordneten Mitteln für Induktivitäts- und Kopplungsabgleich.The drawing shows, for example schematically, an embodiment the invention of a ring provided with a crossbar with two to be coupled together Coils and the associated means for inductance and coupling adjustment.
In diesem Ring ist der Quersteg mit 2 bezeichnet, während die beiden miteinander zu koppelnden Spulen mit 3 und 4 bezeichnet sind. Der Quersteg 2 enthält eine Bohrung 5, in die zur Änderung der Kopplung ein Abgleichkern eingeführt werden kann. Die beiden die Spulen 3 und 4 tragenden Ringsektoren enthalten ihrerseits weitere Durchlochungen 6 und 7, in die zum Abgleich der Induktivität der Spulen weitere Stifte verschiebbar eingesetzt sind.In this ring, the crosspiece is labeled 2, while the two Coils to be coupled to one another are denoted by 3 and 4. The crosspiece 2 contains a bore 5, into which an adjustment core can be inserted to change the coupling can. The two ring sectors carrying the coils 3 and 4 contain their part further perforations 6 and 7, in which to adjust the inductance of the coils further pins are inserted displaceably.
