Description
Verfahren zum Herstellen von Spulenkörpern mit Metallkern und Spulenscheiben aus Isoliermaterial für Spulen zu elektrischen Zwecken, insbesondere zu solchen der Fernmeldetechnik Gegenstand des Patents ./.78 316 ist ein Verfahren zum Herstellen von Spulenkörpern mit Metallkern und Spulenscheiben aus Isoliermaterial für Spulen zu elektrischen zwecken, insbesondere zu solchen der Fernrneldetechnik; es besteht darin, daß die aus isolierendem Preß-, Spritz- oder Gußmaterial bestehenden Spulenscheiben gleichzeitig mit ihrer Herstellung auf dem Spulenkern durch Spritzen, Pressen oder Gießen befestigt werden. In weiterer Ausgestaltung dieses Verfahrens betrifft die Erfindung ein Verfahren, hei dem erfindungsgemäß gleichzeitig mit der Herstellung der Spulenscheiben auf dein metallenen Spulenkern eine ihn urigebende Isolierschicht angebracht wird.Process for the manufacture of bobbins with a metal core and bobbin washers Made of insulating material for coils for electrical purposes, in particular for such of telecommunications technology The subject of the patent ./.78 316 is a method of manufacturing of coil bobbins with a metal core and coil washers made of insulating material for coils for electrical purposes, in particular for telecommunications; it exists in that the insulating pressed, injection-molded or cast material coil disks simultaneously with their manufacture on the coil core by injection molding, pressing or Casting to be attached. In a further embodiment of this process, the Invention a method, called the invention simultaneously with the production the coil washers on your metal coil core a rustic insulating layer is attached.
Die Isolierschicht selbst kann auf verschiedene `'Verse auf den Spulenkern aufgebracht werden. Es ist möglich, gleichzeitig rnit der Fertigung der Spulenscheiben um den Kern eine dünne Schicht Isoliermaterial herumzupressen, -zugießen oder -ztispritzen. Diese Schicht bildet dann zusammen rnit den Spulenscheiben einen einzigen lroinogenen Körper aus Isoliermaterial, der den metallenen Kern umgibt. Abb. I zeigt einen nach einem derartigen Verfahren gefertigten Spulenkörper. 3 ist der metallene Kern, urn den die isolierende Hülle 12 gelegt ist, die mit den Spulenscheiben i und 2 einen einheitlichen Körper bildet.The insulating layer itself can be applied to various '' verses on the coil core be applied. It is possible to manufacture the reel discs at the same time to press, pour or spray a thin layer of insulating material around the core. This layer then forms a single ionogenic together with the coil disks Body made of insulating material that surrounds the metal core. Fig. I shows one after such a method manufactured bobbin. 3 is the metal core, urn which the insulating sheath 12 is placed, with the coil disks i and 2 one forms a unified body.
Die Form, in der ein derartiger Spulenkörper hergestellt werden kann, ist in Abb. 3 als Ausführungsbeispiel gezeichnet.The form in which such a bobbin can be manufactured is drawn in Fig. 3 as an embodiment.
Mit einer geeigneten Spritz- oder Preßvorrichtung wird in an sich bekannter Weise die Isolationsmasse in die Trichter 6 und 7 geleitet und strömt von hier aus in die für die Schaffung der Spulenscheiben i, 2 sowie der isolierenden Hülle 12 vorgesehenen Hohlräume.With a suitable spraying or pressing device is in itself In a known manner, the insulation compound is passed into the funnel 6 and 7 and flows from here into the one for creating the coil disks i, 2 as well as the insulating ones Sheath 12 provided cavities.
Es gibt jedoch noch andere Arten, entsprechend dein Erfindungsgedanken gleichzeitig mit der Fertigung der Spulenscheiben eine Isolierschicht um den Kern anzubringen. Das kann so bewerkstelligt «erden, daß man vor Einlegen des Kerns in eine der Abb. 3 entsprechende Form auf den Kern eine Hülse aus einem guten und geeigneten Isoliermaterial, vor allem Kunstharzhartpapier, aufschriebt oder,die Hülle durch Umwickeln bildet und dann diese Hülse zusammen mit der nach dein Verfahren des Hauptpatents bewirkten Herstellung der Spulenscheiben festpreßt. Die Hülle ragt, wie es Abb. 2 zeigt, in die Masse der Spulenscheiben hinein und bekommt durch den überstehenden Randteil der Spulenscheiben festen Halt auf dem Kern.There are other types, however, according to your invention an insulating layer around the core at the same time as the coil washers are manufactured to attach. This can be done in such a way that, before inserting the core, one in a shape corresponding to Fig. 3 on the core a sleeve made of a good and suitable Insulating material, especially synthetic resin hard paper, writes on or through the envelope Wrapping forms and then this sleeve together with the according to the procedure of the main patent caused production of the reel discs. The shell protrudes as shown in Fig. 2 shows into the mass of the reel discs and gets through the protruding edge part of the reel washers hold firmly on the core.
Auf beide geschilderte Arten, sowohl das Herstellen der Kernumhüllung zugleich mit den Spulenscheiben als auch das Überschieben und Festpressen der Hülse durch die Spulenscheiben, werden die sonst auftretenden Schwierigkeiten der Papierisolation des Kerns restlos vermieden. Die Isolation des Spulenkeznms ist eine vollkommeirne, und der Wickelraum wird fugenlos so aufgebaut, daß ein lagenweises Wickeln des Drahtes gewährleistet ist.In both ways described, both the production of the core cladding at the same time with the reel washers as well as pushing and pressing the sleeve over through the spool washers, the difficulties of paper insulation that otherwise arise of the core completely avoided. The insulation of the coil core is perfect, and the winding space is built up seamlessly so that the wire can be wound in layers is guaranteed.
