Description
Die vorliegende Erfindung bezieht sich auf einen Hochfrequenztransformator, dessen Spulenwicklungen als fortlaufende Leiterbahnen windungsförmig auf einer Isolierstoffplatte aufgebracht sind, und der einen geschlossenen Ferritkreis aufweist, der aus die Spulenwicklungen etwa mittig durchsetzenden Kernen und diese verbindenden Kernbrücken besteht, die an einer Platte gehaltert sind.The present invention relates to a high frequency transformer, its coil windings are applied as continuous conductor tracks in the form of turns on an insulating plate, and the one has closed ferrite circuit, which consists of the coil windings approximately centrally penetrating cores and this connecting core bridges is made, which are supported on a plate.
Ein derartiger Hochfrequenztransformator ist aus dem DT-GBm 19 72122 bekannt. Dabei sind die Isolierstoffplatten mit den auf ihnen aufgebrachten Transformatorwicklungen von einer Schicht aus in Kunststoff eingebettetem Ferritmaterial umgeben. Diese Ferritschicht erstreckt sich daher an den Seiten der Isolierstoffplatte über dieselbe hinaus.Such a high-frequency transformer is known from DT-GBm 19 72122. There are those Insulation panels with the transformer windings applied to them from a layer in Plastic embedded ferrite material surrounded. This ferrite layer therefore extends on the sides of the insulating plate over the same.
Aufgabe der vorliegenden Erfindung ist es, eine Bauart von Hochfrequenztransformatoren der eingangs genannten Art anzugeben, welche ein geringeresThe object of the present invention is to provide a type of high-frequency transformer of the initially mentioned indicated type, which is a lower
ίο Bauvolumen aufweist und bei der zusätzlich das die Spulenkerne miteinander verbindende Ferritmaterial besser gegen äußere mechanische Beschädigungen geschützt istίο has construction volume and in addition that the Ferrite material connecting coil cores to each other better protects against external mechanical damage is protected
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Isolierstoff platte aus zwei übereinanderliegenden Platinen besteht, die mit zwei Bohrungen zur Aufnahme der Kerne und auf ihren einander abgewandten Seiten jeweils mit einer Rinne zur Aufnahme der Kernbrücken versehen sind, und daß zwischen den beiden Platinen die auf eine Zwischenschicht aufgebrachten Spulenwicklungen angeordnet sind.This object is achieved in that the insulating plate consists of two superimposed There are circuit boards with two holes for receiving the cores and facing away from each other Pages are each provided with a channel for receiving the core bridges, and that between the two circuit boards which are arranged on an intermediate layer of coil windings.
Ein Ausführungsbeispiel der Erfindung samt einer weiteren Ausgestaltung, welche in dem Unteranspruch gekennzeichnet ist, wird nachstehend anhand der Zeichnung näher erläutert.An embodiment of the invention including a further embodiment, which in the dependent claim is marked, is explained in more detail below with reference to the drawing.
Die Fig. 1 veranschaulicht in ihren Teilen la und \b in einer Aufsicht bzw. in einer Seitenansicht die Plaiinen bzw. Folien 3 und Sa. Die Wicklungsspiralen 1,2 sind auf einer zwischen den Platinen 3 und 3a befindlichen Zwischenschicht 8 aufgebracht. Die Kernscheiben bzw. -stifte 4,5 durchsetzen die Platinen bzw. Folien 3 und 3a nicht völlig und die Kernbrücken 6 bzw. 7 sind in Rinnen der Platinen- bzw. Folienoberseiie und -Unterseite derart eingebettet, daß sie bündig mit der Oberseite der Platine 3 bzw. der Unterseite der Platine 3a abschließen.1 illustrates the plains or foils 3 and Sa in their parts la and \ b in a plan view or in a side view. The core disks or pins 4, 5 penetrate the boards or foils 3 and 3a completely and the core bridges 6 and 7 are embedded in grooves in the board or foil top and bottom in such a way that they are flush with the top of the board 3 or the underside of the circuit board 3a.
