Hierbei ist es vorteilhaft, daß die infrage stehende Trennwand aus einer zwischen die Flansche der Spulenkörper der Primär- und Se.-candärwicklur.g eingefügten, tiefgezoger.en Isolierfolie bestent.It is advantageous that the partition in question from one between the flanges of the coil formers of the primary and Se.-candärwicklur.g inserted, deep-drawn.en insulating film best.

Es besteat aber auch als zweite erfinderisene Lösung die --öglichkeit, daß der die Primärwicklung von der in Achsrichtung danebenliegenden Sekundärwicklung trennende und senkracht stener.-de Flanscn des oder der Spulenkörper in Achsrichtung augewin.celt und in Achsrichtung verlängert isto As a second inventive solution, however, it also offers the possibility of the flanges separating the primary winding from the adjacent secondary winding in the axial direction and lowering the flange (s) of the coil body (s) in the axial direction and lengthening it in the axial direction, or the like

Die Zeichnung zeigt zwei Ausfünrungsbeispielo der lieuarong.The drawing shows two examples of the lieuarong.

Bei der Ausführung nach Figur 1 sind die aαχ den Transformatorkern 1 aufzuschiebenden SpulenKörper 21 für die Primärwicklung und SpulenKörper 31 für die Sekundärwicklung 3 durch eine zwischen deren Flanscne 22 and 32 eingeschobene Trennwand 4 getrennt, die eine tiefgezogene Isolierfolie ist. Damit entstent ein in der Achsrichtung der Spulen verlängerter umlaufender Ansatz 41, der sowohl die Kriechstrecke als auch die Luftstrecke zwischen den kürzesten Abständen der Primärwicklung 2 und Sekundärwicklung 3 verlängert.In the embodiment of Figure 1, the aαχ are the transformer core 1 to be pushed on bobbin 21 for the primary winding and bobbin 31 for the secondary winding 3 through an intermediate whose flanges 22 and 32 inserted partition 4 are separated, which is a deep-drawn insulating film. This creates an in the axial direction of the coils extended circumferential shoulder 41, which is both the creepage distance and the air gap between the shortest distances between the primary winding 2 and the secondary winding 3 extended.
