Description

Spulenanordnung von zwei veränderlich miteinander koppelbaren Selbstinduktionsspulen Die Erfindung betrifft eine Spulenanordnung von zwei veränderlich miteinander koppelbaren Selbstinduktionsspulen, deren Wicklungen ein Hochfrequenzeisenkernm:anbel außen umschließt. Es ist bei solchen Selbstinduktionsspulen bereits bekannt, den Wickelkörper mit Muttergewinde zu versehen, welches einen als Schraubkern ausgebildeten, die Wicklungen durchdringenden Kernteil aufnimmt. Es sind ferner Spulenanordnungen bekannt, bei welchen zwei "in Reihe geschaltete Spulenhälft.en durch einen einzigen Eisenkern miteinander gekoppelt werden können. Bei den bekannten Spulenanordnungen fehlt die Möglichkeit, die miteinander koppelbaren Spulen je für sich induktiv abzugleichen. Schließlich ist eine Spulenanordnung bekanntgeworden, bei welcher auf einem zylindrischen Eisenkern zwei Spulenrvickelkärper voneinander unabhängig verschoben werden können.Coil arrangement of two mutually variable self-induction coils The invention relates to a coil arrangement of two that can be variably coupled to one another Self-induction coils, the windings of which have a high-frequency iron core: anbel outside encloses. It is already known in such self-induction coils, the winding body to be provided with a nut thread, which is designed as a screw core, the Receives windings penetrating core part. There are also known coil arrangements, in which two "series-connected Spulenhälft.en through a single iron core can be coupled with each other. In the known coil arrangements that are missing Possibility of inductively matching the coils that can be coupled to one another. Finally, a coil arrangement has become known in which on a cylindrical Iron core two bobbins can be moved independently of each other.

Der Erfindung liegt die Aufgabe zugrunde, eine Spulenanordnung einfacher und billiger Ausführung zu schaffen, bei welcher sowohl der Kopplungsgrad der beiden Spulen als auch die Induktivität der beiden Spulen je für sich einstellbar sind. Erreicht wird dies gemäß der Erfindung durch einen beiden Spulen und zugehörigen Schraubkernen gemeinsamen Wickelkörper, der von einem in Richtung der Spulenlängsachse geteilten Topfkern umschlossen ist und zwischen den Spulen Hochfrequenzeisenstücke und gegebenenfalls einen zusätzlichen Schraubkern enthält. Durch diese Anordnung erreicht man, daß sich der Kopplungsgrad der Spulen ändern läßt, ohne daß es besonderer, den Aufbau des Spulensatzes komplizierender Einrichtungen bedarf. Es kommt hinzu, daß infolge der Abschirmwirkung des den Spulens:atz vollständig umschließenden Eisenkernmantels der Kopplungsgrad zwischen den Spulen durch in unmittelbarer Nähe angeordnete, hochfrequenzführende Schaltelemente nicht beeinflußt werden kann.The invention is based on the object of simplifying a coil arrangement and to create cheaper execution in which both the degree of coupling of the two Coils as well as the inductance of the two coils can be adjusted individually. This is achieved according to the invention by two coils and associated Screw cores common winding body, which is from one in the direction of the coil longitudinal axis split pot core is enclosed and between the coils high frequency iron pieces and optionally contains an additional screw core. Through this arrangement it is achieved that the degree of coupling of the coils can be changed without any particular, the construction of the coil set requires complicating facilities. In addition, that as a result of the shielding effect of the coil: etz completely enclosing iron core jacket the degree of coupling between the coils by means of high-frequency conductors arranged in the immediate vicinity Switching elements cannot be influenced.

Ein Ausführungsbeispiel des Gegenstandes der Erfindung zeigt die Zeichnung, und zwar Abb. r im Schnitt und Abb. 2 in Draufsicht. Die Topfkernhälften a und b bilden zwei Schalen mit halbkreisförmigen Mantelflächen. Innerhalb der Topfkernhälften a und b ist der beiden Spulen f und g und zugehörigen Schraubkernen d und e gemeinsame Wickelkörper c untergebracht. Die axiale und radiale Bewegung des Wickelkörpers c wird durch die Wandungen der Topfkernhälften a und b verhindert. Die Sicherung des Wickelkörpers c gegen Drehen erfolgt mittels an der Topfkernhälfte b angepreßter Nasen h und zugehöriger Nuten in den Flanschen des Wickelkörpers c. Der Kopplungsgrad der beiden Spulen f und g wird dadurch verändert, daß man gegebenenfalls zwischen den Spulen Zwischenstücke lt aus Hochfrequenzeisen anbringt. Auch innerhalb des Wickelkörpers kann ein kurzer Schraubkern i zwischen den eigentlichen Ab.gleichkernen rl und e vorgesehen werden. Die Befestigung der Zwischenstücke lt geschieht entweder in der Weise, daß man sie unmittelbar an die Kernhälften -a und b mit anpreßt, oder daß man besondere halbringförmige Stücke lt aus Hochfrequenzeisen an den Kernhälften a und b durch Leimen, Kitten o. dgl. befestigt. Durch Änderung der Stärke der Zwischenstücke h und des Schraubkerns i läßt sich der Kopplungsgrad der Spulen f und g in weitgehendem Maße verändern. Der Abgleich der Induktivität der Spulen f und ä erfolgt in üblicher Weise durch Einstellung der Schraubabgleichkerne d und e.An embodiment of the subject of the invention is shown in the drawing, namely Fig. R in section and Fig. 2 in plan view. The pot core halves a and b form two shells with semicircular outer surfaces. Inside the pot core halves a and b , the two coils f and g and the associated screw cores d and e are housed common bobbins c. The axial and radial movement of the winding body c is prevented by the walls of the cup core halves a and b. The bobbin c is secured against rotation by means of lugs h pressed against the pot core half b and associated grooves in the flanges of the bobbin c. The degree of coupling of the two coils f and g is changed by attaching intermediate pieces made of high-frequency iron between the coils. A short screw core i can also be provided between the actual alignment cores rl and e within the winding body. The attachment of the intermediate pieces is done either in such a way that they are pressed directly onto the core halves -a and b, or that special semi-ring-shaped pieces made of high-frequency iron are attached to the core halves a and b by glueing, cement or the like. By changing the thickness of the intermediate pieces h and the screw core i , the degree of coupling of the coils f and g can be changed to a large extent. The adjustment of the inductance of the coils f and ä takes place in the usual way by setting the screw adjustment cores d and e.
