Description
Für die isolierte Durchführung von blanken Leitern, wie Schrauben, Bolzen od. dgl., durch Metallplatten hat man bisher Isolierhülsen verwendet. Die Durchführungsbolzen-mußten durch isolierte Muttern .gegen Verschieben und Verdrehen gesichert werden. Durch die mechanische Befestigung können leicht Beschädigungen oder Zerstörungen der Isolierteile eintreten.For the insulated passage of bare conductors such as screws, Bolt or the like. Insulating sleeves have so far been used by metal plates. the Bushing bolts had to be secured by insulated nuts against shifting and twisting secured. The mechanical fastening can easily damage it or destruction of the insulating parts.
Durch die Erfindung wird die Herstellung einer elektrisch isolierten Leitungsdurchführung- verbessert und wesentlich vereinfacht. Sie macht dabei Gebrauch von einem bekannten Verfahren, bei ,dem zur Herstellung eines isolierenden Überzuges Kunstfolienstreifen auf einen Leiter aufgewickelt" und durch Wärmebehändlung aufgeschrumpft werden. Der spiralig aufgewickelte Folienstreifen ist quer zur Aufwicklung gereckt.The invention enables the production of an electrically insulated Cable entry improved and significantly simplified. She makes use of it of a known method in which for the production of an insulating coating Art film strips wound up on a conductor "and shrunk on by heat treatment will. The spirally wound film strip is stretched across the winding.
Erfindungsgemäß wird der: Leiter so in die Durchführungsöffnung der Metallplatte eingebracht, daß der Folienstreifen die vorzugsweise mit einer Einkerbung oder mehreren Einkerbungen versehene oder unrunde Durchführungsöffnung beiderseits überragt und sich beim Schrumpfvorgang an den die Durchführungsöffnung überragenden Teilen Verdickungen des Folienstreifens ergeben, die die Verfestigung der Durchführung in der Metallplatte bewirken.According to the invention is the: Head so in the lead-through opening of the Metal plate introduced that the foil strip which is preferably with a notch or several notches provided or non-circular feed-through opening on both sides protrudes and during the shrinking process on the protruding from the feed-through opening Part of the thickening of the film strip results in the solidification of the implementation effect in the metal plate.
Die Erfindung soll an Hand -des in den Fig. i bis 3 dargestellten Ausführungsbeispiels näher erläutert werden.The invention is intended to be based on the illustrated in FIGS Exemplary embodiment will be explained in more detail.
Fig. i zeigt die Isolierung der Durchführung vor dem Schrumpfvorgang, die Fg. a .nach dem Schrumpfvorgang, beide- im Schnitt, und Fig. 3 einen längs gereckten Folienstreifen.Fig. I shows the insulation of the bushing before the shrinking process, Fig. a. after the shrinking process, both in section, and Fig. 3 a longitudinally stretched Foil strips.
In Fig. i ist ,der als Schraube ausgebildete Leiter i .durch die Metallplatte 2 durchgeführt. Um die Schraube z ist ein Kunststoffolienstreifen 3 spiralig so aufgewickelt, daß er das Durchführungsloch ,4 beidseitig mit seinen Enden 5 und 6 überragt. Das kreisförmige Loch 4 hat eine Einkerbung 7. Der Fohenstreifen 3 ist von einem größeren. längs gereckten Streifen 8 nach Fig: 3 durch Trennen in Querrichtung abgeschnitten: Der abgeschnittene Streifen ist in seiner Querrichtung (Pfeilrichtung) gereckt. Wird daher der in die Durchführung quer zur Pfeilrichtung spiralig gewickelte Folienstreifen erwärmt, so schrumpft er in Richtung der Schraubenachse und bildet nach Fig. 2 das Durchführungsloch 4 übergreifende. Verdickungen 9 und io. Bei dem Schrumpfvorgang werden auch die Gewinderillen der Schraube i von dem erweichten Kunststoff derart dicht ausgefüllt, daß die Schraube nicht nur unverschiebbar, sondern auch unverdrehbar befestigt ist.-Auch die Einkerbung 7 wird von dem Kunststoff ausgefüllt, wodurch die durch ihn gebildete Isolierhülse nach dem Erkalten ebenfalls unverdrehbar festgehalten wird. Bei glattem Durchführungsbolzen kann man durch Einkerbungen der Bolzen diesen ebenfalls unverschiebbar und unverdrehbar festlegen.In Fig. I, the conductor formed as a screw i .through the metal plate 2 carried out. To the screw z is a plastic film strip 3 spirally so wound that he has the through hole, 4 on both sides with its ends 5 and 6 towers above. The circular hole 4 has a notch 7. The foil strip 3 is from a bigger one. longitudinally stretched strip 8 according to FIG. 3 by cutting in the transverse direction cut off: The cut strip is in its transverse direction (arrow direction) stretched. Therefore, the spiral wound into the bushing transversely to the direction of the arrow Heated foil strip, so it shrinks in the direction of the screw axis and forms according to Fig. 2, the through hole 4 overlapping. Thickenings 9 and io. In which The shrinking process will also soften the thread grooves of the screw i Plastic so tightly filled that the screw is not only immovable, but is also fixed so that it cannot rotate. - The notch 7 is also filled by the plastic, whereby the insulating sleeve formed by it also cannot rotate after cooling is being held. In the case of a smooth lead-through bolt, the Fix the bolt in such a way that it cannot be moved or rotated.
Die Erfindung kann sowohl für einfache Durchführungen als auch für Klemmenbolzendurchführungen od.,dgl. verwendet werden. Die Durchführungen können durch das neue Verfahren schneller und mit geringerem Aufwand als bisher hergestellt werden.The invention can be used both for simple implementations and for Terminal bolt feedthroughs or the like. be used. The bushings can produced faster and with less effort than before thanks to the new process will.
