Description

Patentansprüche: 1. Zeilentransformator, dadurch g e k e n n -z e i c h n e t, daß der Wickel der Primärwicklung aus einer metallischen Folie besteht, daß zwischen die metallische Folie als Isolation eine Kunststoff-Folie eingelegt ist, daß die einzelnen Abgriffe aus quer zur Wicklung eingelegten und eingewickelten Drähten besteht, und daß die äußeren Folienränder verschweißt oder verschrumpft sind.Claims: 1. Line transformer, thereby g e k e n n -z e i c h n e t that the winding of the primary winding consists of a metallic foil, that a plastic film is inserted between the metallic film as insulation is that the individual taps are inserted and wrapped transversely to the winding There are wires, and that the outer edges of the film are welded or shrunk are.

2. Zeilentransformator nach Anspruch 1, dadurch gekennzeichnet, daß die Wicklung aus kaschierter Kunststoff-Folie besteht, auf der Leiterbahnen und entsprechende Abgriffe gedruckt sind. 2. flyback transformer according to claim 1, characterized in that the winding consists of a laminated plastic film on which the conductor tracks and corresponding taps are printed.

Es ist bekannt, bei Zeilentransformatoren für die Primärwicklung Runddraht zu verwenden. Solche Wicklungen haben den Nachteil, daß sie viel Wickelraum in Anspruch nehmen, teurer Kupfer-Draht verwendet werden muß und eine kostspielige, komplizierte Wickeltechnik angewendet wird, da zur Vermeidung hoher Stromverdrängung, die bei großen Drahtquerschnitten auftritt, Drähte mit geringerem Querschnitt mehrfach parallel gewickelt werden müssen. It is known in flyback transformers for the primary winding Use round wire. Such windings have the disadvantage that they have a lot of winding space take up, more expensive copper wire must be used and an expensive, complicated winding technology is used, since to avoid high current displacement, which occurs with large wire cross-sections, wires with smaller cross-sections several times must be wound in parallel.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Fertigungsverfahren zu finden, das ein billigeres, einfacheres und elektrisch unproblematisches Wickeln ermöglicht. The invention is therefore based on the object of a manufacturing method to find the one cheaper, easier and electrically unproblematic winding enables.

Diese Aufgabe wird dadurch gelöst, daß statt Runddraht zum Wickeln eine metallische Folie, z. B. This object is achieved in that instead of round wire for winding a metallic foil, e.g. B.

Aluminium, verwendet wird. Zwischen diese metallische Folie wird zur Isolation eine Kunststoff-Folie gelegt.Aluminum, is used. Between this metallic foil is used Isolation put a plastic film.

Die einzelnen Abgriffe werden dadurch erzielt, daß an den entsprechenden Abgriffstellen Runddraht quer zum Folienwickel eingelegt und mit eingewickelt wird. Ein luftdichter Verschluß der Wicklung kann dadurch erreicht werden, daß die äußeren Folienränder verschweißt oder geschrumpft werden.The individual taps are achieved in that the corresponding Tapping points round wire is inserted across the foil wrap and wrapped with it. An airtight seal of the winding can be achieved that the outer Foil edges are welded or shrunk.

Durch dieses erfindungsgemäße Wickelverfahren wird ein erheblich geringerer Wickelraum benötigt. This winding method according to the invention makes a considerable less changing room required.

Aluminium ist billiger als Kupfer. Eine aus Folienmaterial gewickelte Spule wird weniger warm und hat eine geringere Eigenkapazität, da kapazitätsarme Wicklungen. Durch Verwendung von Folie ist eine möglichst große Drahtoberfläche erzielt worden. Durch die geringe Stärke der Folie, ist die Stromverdrängung vernachlässigbar klein. Weitere Vorteile sind eine gleichmäßige Wärmeverteilung und eine niedrige Lagenspannung, da jede Lage eine Windung.Aluminum is cheaper than copper. One wound from foil material The coil becomes less warm and has a lower self-capacitance because it has a low capacitance Windings. By using foil, the largest possible wire surface is possible has been achieved. Due to the low thickness of the foil, the current displacement is negligible small. Further advantages are an even heat distribution and a low one Layer tension, since each layer is one turn.

Claims (1)

Eine weitere Einsparung des Wickelgutes kann dadurch erzielt werden, daß statt Aluminium-Folie und Kunststoff-Folie eine kaschierte Kunststoff-Folie verwendet wird, auf der mehrere parallel verlaufende Leitungszüge mit entsprechenden Abgriffen gedruckt sind. A further saving of the winding material can be achieved by that instead of aluminum foil and plastic film, a laminated plastic film is used, on which several parallel cable runs with corresponding Taps are printed.
