Abstract

The HF transformer consists of two windings inductively coupled by a ferrite core and all held by two support boards. The windings consist of spirals (1, 2) formed on the surface (8) of one board (3) and covered by the second board (3a). The ferrite core consists of two posts (4, 5) extending through both boards along the respective axes of the spirals. The ends of the posts are joined by two ferrite bridges (6, 7) recessed into the outer surfaces of the boards and forming a closed loop core.

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.

Iiin derartiger Hochfrequenztransformator ist aus dem DT-GBm 19 72 122 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 off the DT-GBm 19 72 122 known. The insulation panels are attached to them with the Transformer windings are surrounded by a layer of ferrite material embedded in plastic. This ferrite layer therefore extends on the sides of the insulating plate over the same.

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 ib in einer Aufsicht bzw. in einer Seitenansicht die Platinen bzw. Folien 3 und 3a. 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. Folienoberseite und -Unterseite derart eingebettet, daß sie bündig mit der Oberseite der Platine-3 bzw. der Unterseite der Platine 3a abschließen.Fig. 1 illustrates in its parts la and ib in a plan view and in a side view, the boards or foils 3 and 3a. The winding spirals 1, 2 are applied to an intermediate layer 8 located between the circuit boards 3 and 3a. 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.
