Description

Es ist vorgeschlagen worden, bei auf Flanschspulenkörpern gewickelten Spulen für elektrische Geräte, z. B. Zählerspannungsspulen, dadurch den Raum besser für die Wicklung auszunutzen, daß man einen Spulenkörper verwendet, dessen Schaft auL9 einer oder mehreren Lagen dünner Kunststofffolien besteht und dessen aufgesteckte und gegebenenfalls aufgeklebte oder sonstwie damit vereinigte Flansche aus Kunststoff gespritzt oder gegossen sind. Gibt man den Flanschen auf de: Innenseite eine Kegelform, dann kann leicht ohne Verwendung von Papierzwischenlagen der ganze Raum zwischen den Flanschen vollgewickelt werden. Da jetzt aber die Wicklung bis zu den Flanschrändern heranreicht, sind die Kriechwege zwischen Wicklungsumfang und den angrenzenden Metallteilen, insbesondere Eisenkernteilen, verhältnismäßig kurz.It has been suggested to be wound on flanged bobbins Coils for electrical equipment, e.g. B. Counter voltage coils, this makes the room better to take advantage of the winding that one uses a bobbin, the shaft of which auL9 consists of one or more layers of thin plastic film and its attached and optionally glued-on or otherwise combined flanges made of plastic are injected or poured. If you give the flanges on the inside a cone shape, then all the space between can easily without the use of paper interleaves the flanges are fully wrapped. But now the winding up to the flange edges the creepage distances between the circumference of the winding and the adjacent metal parts, especially iron core parts, relatively short.

Die Erfindung hat die Aufgabe, bei solchen oder ähnlichen Spulen an dieser Stelle die Kriechweglängen zu vergrößern. Es wird dabei vorausgesetzt, daß wenigstens die Flansche des Spulenkörper s aus gespritztem oder gegossenem, biegsamem Kunststoff bestehen.The invention has the object of such or similar coils to increase the creepage distances at this point. It is assumed that at least the flanges of the bobbin made of injection-molded or cast, flexible Made of plastic.

Erfindungsgemäß setzen sich die Flansche in Lappen fort, die auf den Spulenumfang niedergebogen sind. Am besten macht man die Lappen so lang, daß sie sich mit ihren vorzugsweise verjüngten Enden überdecken. Der Spulenumfang ist dann durch diese Lappen gegen vorbeigeführte leitende Teile abgeschirmt. Läßt man die Lappenränder genügend weit über diese Teile vorspringen, dann ergeben sich an allen Stellen ausreichende Kriechweglängen.According to the invention, the flanges continue in tabs on the Coil circumference are bent down. It is best to make the lobes so long that they overlap with their preferably tapered ends. The coil circumference is then shielded by these cloths against conductive parts passed by. If you leave that The edges of the flaps protrude sufficiently far beyond these parts, then result on all of them Provide sufficient creepage distances.

Ein Ausführungsbeispiel der Erfindung ist in der I_enchnung dargestellt. Auf einem Mittelschenkel i (Fig. i) eines nur hälftig gezeichneten Spannungseisens eines Zählers sitzt eine Wicklung 2. Zwecks Isolation ist der Mittelschenkel i mit einer oder mehreren Lagen einer Kunststoffolie 2 umhüllt, .die einen dünnwandigen, aber elektrisch sehr hochwertigen Schaft eines Spulenkörpers bilden. Auf diesen Schaft sind aus Kunststoff gespritzte, konische Flanschteile 3 aufgesteckt, aufgeklebt oder sonstwie damit vereinigt. Die Flanschteile setzen sich in Lappen 4 fort, die an ihren Enden g verjüngt sind und sich überdecken.One embodiment of the invention is shown in the analysis. On a middle leg i (Fig. I) of a tension iron only drawn in half of a meter there is a winding 2. For the purpose of isolation, the middle leg i is with one or more layers of a plastic film 2, .the one thin-walled, but electrically form a very high quality shaft of a bobbin. On this Shaft are made of plastic injection-molded, conical flange parts 3 plugged on, glued on or otherwise associated with it. The flange parts continue in tabs 4, the are tapered at their ends g and overlap.

In den Fig. 2 und 3 ist ein solcher Flanschteil in zwei verschiedenen Ansichten dargestellt, doch sind hier die Lappen q. noch nicht umgebogen. Sie werden erst nach dem Aufspulen der Wicklung umgelegt, damit sie das Aufspulen nicht behindern.In Figs. 2 and 3, such a flange part is in two different ways Views shown, but here the lobes q. not bent yet. you will be only folded over after the winding has been wound up so that they do not interfere with winding.

INTatürlich können die Flansch- und Schaftteile auch zusammengespritzt werden, und man erhält dann einen einteiligen Spurenkörper. Statt dessen kann man auch nur den einen Flanschteil an den Schaft mit anspritzen und den anderen Flanschteil für sich herstellen.INT Of course, the flange and shaft parts can also be injected together and you get a one-piece trace body. Instead, you can also inject only one flange part onto the shaft and the other flange part manufacture for yourself.
