Das Wicklungsende mit der Sonderisolation wird aus der Aussparung herausgeführt und an dem knopfartig vorspringenden Teil festgeklemmt.insulation ends in the associated groove-like recess or in the associated slot, whereby the transition point between 'winding wire and special insulation outside the winding space located. The end of the winding with the special insulation is led out of the recess and attached clamped to the button-like protruding part.

Mit 1 ist der Flanschspulenkörper mit seinen beiden Flanschen! und 3 und mit 4 die darauf aufgebrachte Wicklung bezeichnet. Die beiden Wicklungsenden 5 und 6 (Anfang 5 und Ende 6), die mit einer Sonderisolation 7, z. B. Isolierschlauch, versehen und« meist auch verstärkt sind, sind je durch den Flansch 2 durch einen darin vorgesehenen Schlitz 8 herausgeführt. Diese Schlitze 8 können auf gleichen oder verschiedenen Seiten des Flansches angebracht sein, und sie können den Flansch senkrecht oder dazu schräg geneigt durchsetzen, wie dies in F i g. 2 zu sehen ist. Der Flansch 2 besitzt eine quer über die ganze Flanschbreite reichende Leiste 11, zwischen der und dem Flansch 2 auf den beiden Außenseiten je eine parallel zur Flanschebene verlaufende nutartige Aussparung 12 vorgesehen ist. Auf der Leiste 11 sitzt den Schlitzen 8 benachbart je ein knopf artig vorspringender Teil, dessen Hals mit 13 und dessen Knopfstück mit 14 bezeichnet ist. Die freie Breite der nutartigen Aussparung 12 ist entsprechend der Dicke des mit Isolierschlauch 7 versehenen, gegebenenfalls verstärkten Wicklungsendes bemessen, und in gleicher Weise ist auch der zur Erhöhung der Klemmwirkung keilförmig ausgebildete Abstand des Knopfstückes 14 von der Leiste 11, d. h. die Höhe des Halses 13, bemessen. In dem Flansch 2 werden die beiden Wicklungsenden 5,6 nach mehrfacher Verbiegung festgelegt und vor allem so festgehalten, daß eine zusätzliche Zugentlastung überflüssig ist. Dies erreicht man dadurch, daß das Wicklungsende 5 vor Beginn der Wickelarbeit zunächst um den Hals 13, dann über die Leiste 11, und zwar über eine darin vorgesehene Kerbe 15, in die nutartige Aussparung 12 übergeführt und von dieser durch den Schlitz 8 auf den Spulenkörpergrund geführt wird. Die Herausführung des Wicklungsendes 6 nach Beendigung des Wickelvorgangs durch den Flansch 2 geschieht in gleicher, jedoch umgekehrter Reihenfolge. Sobald die beiden Wicklungsenden 5,6 mit der angegebenen mäanderartigen Mehrfachverbiegung am Flansch 2 festgelegt sind, bleibt diese Halterung zuverlässig bestehen, und eine auf die Wicklungsenden ausgeübte Zugkraft bleibt für die Wicklung selbst völlig unschädlich. With 1 the flange bobbin with its two flanges! and 3 and with 4 the one applied to it Winding called. The two winding ends 5 and 6 (beginning 5 and end 6) that start with a Special insulation 7, e.g. B. insulating tube, provided and «are usually reinforced, are depending on the Flange 2 led out through a slot 8 provided therein. These slots 8 can be on the same or different sides of the flange, and they can be perpendicular to the flange or to it enforce obliquely inclined, as shown in FIG. 2 can be seen. The flange 2 has a across the entire flange width reaching bar 11, between and the flange 2 on the two outer sides a groove-like recess 12 running parallel to the flange plane is provided. On the bar 11 sits the slots 8 adjacent each a button-like protruding part, the neck with 13 and the Button piece is designated with 14. The free width of the groove-like recess 12 corresponds to the thickness dimensioned of the winding end provided with insulating tube 7, possibly reinforced, and in the same way Wise is also the wedge-shaped spacing of the button piece to increase the clamping effect 14 from ledge 11, i.e. H. the height of the neck 13 measured. In the flange 2, the two Winding ends 5.6 set after multiple bending and, above all, held in such a way that an additional strain relief is superfluous. This is achieved in that the winding end 5 in front Beginning of the winding work first around the neck 13, then over the bar 11, and over one in it provided notch 15, transferred into the groove-like recess 12 and from this through the slot 8 is guided on the bobbin base. The lead out of the winding end 6 after completion the winding process through the flange 2 takes place in the same, but in reverse order. As soon as the both winding ends 5, 6 with the specified meander-like multiple bending on flange 2 are set, this bracket remains reliable, and one exerted on the winding ends Tensile force remains completely harmless to the winding itself.

Außer den genannten Vorteilen der sicheren Festlegung der Wicklungsenden am Flansch ist vor allem bemerkenswert, daß die Festlegung von Hand in arbeits- und zeitsparender Weise durchführbar ist.In addition to the advantages mentioned, the secure fixing of the winding ends on the flange is above all It is remarkable that the definition can be carried out by hand in a labor-saving and time-saving manner.
