Description
"Zum Schutze gegen Lockern und Abwickeln werden die Enden von Spulenwicklungen mit Schnüren oder Bändern festgebunden oder -geklebt. Dies erfordert viel Zeit und Mühe. Auch besteht die Gefahr, daß sich der festgebundene Teil bei der weiteren Verarbeitung der Spule trotzdem lockert."To protect against loosening and unwinding, the ends of the coil windings Tied or glued with cords or ribbons. This takes a lot of time and Effort. There is also the risk that the part that is tied down will be lost in the further Processing of the coil still loosens.
Die Erfindung hat die Aufgabe, einen leicht lierstellbaren zuverlässigen Schutz gegen Lockern und Abwickeln der Wicklungsenden zu schaffen. Erfindungsgemäß wird der die letzten Windungen bildende Drahtteil mit einem Isolierfilm aus einem anlösbaren, vorzugsweise beim Anlösen schrumpfenden Stoff, wie Triazetat, Polyvinyl od. dgl., umhüllt, und nach dem Wickeln der letzten Windungen werden diese mit einem Anlösemittel, z. B. Methylenchlorid, benetzt. Unter Umständen kann unter oder zwischen die letzten Windungen ein Filmstreifen aus dem gleichen Stoff eingelegt werden.The invention has the object of providing a reliable one that can be easily produced To create protection against loosening and unwinding of the winding ends. According to the invention the wire part forming the last turns is covered with an insulating film made of a dissolvable, preferably shrinking when dissolving, such as triacetate, polyvinyl or the like., enveloped, and after winding the last turns these are with a Solvents, e.g. B. methylene chloride, wetted. Under certain circumstances, under or between the last turns of a film strip made of the same material are inserted.
ach deni benetzen mit dem Anlösemittel kleben wid schrumpfen die letzten Windungen zu einem festen Ring zusammen, der jede Lockerung und Ablösung verhindert. Die Erfindung wird an Hand der Zeichnung näher erläutert.oh, moisten deni with the solvent and glue will shrink the last Windings together to form a solid ring that prevents any loosening and detachment. The invention is explained in more detail with reference to the drawing.
Die letzten Windungen i (Fig. i) einer Spulenwickluiit; sind mit Triazetatfilm 2 umhüllt. Die 1 lullen sind durch Behandlungen mit einem Atilösemittel fest verklebt und verschrumpft. In Fig.2 ist unter die letzten Windungen i ein Filmstreifen 3 eingelegt, der mit den Umhüllungen 2 bei der Behandlung durch ein Anlöseinittel zusammenklebt.The last turns i (Fig. I) of a Spulenwickluiit; are covered with triacetate film 2. The 1 lulls are firmly glued and shrunk by treatment with an atil solvent. In Figure 2, a film strip 3 is inserted under the last turns i, which sticks together with the sheaths 2 during the treatment by a dissolving agent.
Die Erfindung bietet den Vorteil, daß das Wicklungsende auf einfache Weise zuverlässig gesichert wird. Außerdem wird durch den Isolierfilm gleichzeitig die Isolation der Eingangswindungen der Spule verbessert. Die Erfindung eignet sich besonders für dünne bis mittelstarke Drähte.The invention offers the advantage that the end of the winding is easy Way is reliably secured. In addition, through the insulating film at the same time improves the isolation of the coil's input turns. The invention is suitable especially for thin to medium-thick wires.
