Description

Die Erfindung bezieht sich auf eine Spule für den elektromagnetischen Antrieb eines Schaltgerätes mit im Spulenflansch gehaltenen Anschlüssen für die Spule und Ausnehmungen im Flansch zum Einbringen von elektrischen Bauteilen.The invention relates to a coil for the electromagnetic drive of a switching device with connections held in the coil flange for the coil and recesses in the flange for introducing electrical components.

Bei einer bekannten Anordnung der obengenannten Art (DE-PS 36 44 113) sind von zwei benachbarten Eckbereichen des einen Abschlußflansches in Richtung von dessen wesentlicher Erstreckungsebene zwei Anschlußsäulen vorhanden. An der der Wicklung abgewandten Außenfläche dieses Abschlußflansches sind ineinander übergehende und auch mit den Anschlußsäulen in Verbindung stehende Vertiefungen eingeformt, in welche elektrische bzw. elektronische Schaltungselemente einfügbar sind. In den Eckbereichen sind hier die zugehörigen Anschlußdrähte abgewinkelt und können hier im eingebauten Zustand miteinander verlötet werden.In a known arrangement of the type mentioned above (DE-PS 36 44 113), two connecting columns are present from two adjacent corner regions of the one end flange in the direction of its essential extension plane. On the outer surface of this end flange facing away from the winding, recesses which merge into one another and are also connected to the connection columns are formed in which electrical or electronic circuit elements can be inserted. The associated connecting wires are angled in the corner areas and can be soldered to one another here when installed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Spule der obengenannten Art zu schaffen, die eine einfache, automatengerechte Fertigung zuläßt. Dies wird auf einfache Weise dadurch erreicht, daß die Anschlüsse als Lasche ausgebildet der mechanischen Halterung der einen, mit dieser verlöteten Seiten zweier, an gegenüberliegenden Seiten der Lasche angeordneten Dioden einer Diodenbrücke dienen und als Einheit in Ausformungen des Spulenflansches eingelegt sind. Um auf einfache Weise Anwickelpunkte für die Wicklung der Spule zu erhalten, ist es vorteilhaft, wenn die anderen Enden der Dioden über die Fläche des Flansches hinausragen und als Anwickelpunkte für die Wicklung dienen. Um das Verlöten der Dioden mit den Laschen zu vereinfachen, ist es von Vorteil, wenn die Laschen Einstecköffnungen für die Diodenanschlußdrähte aufweisen. Um die Laschen auch sicher im Spulenkörper bei Anschraubbelastung beim Anschrauben der Anschlußdrähte zu halten, ist es von Vorteil, wenn die Laschen in Nuten des Flansches eingeschoben sind. Hierzu ist es weiterhin von Vorteil, wenn die Laschen rechtwinklig abgebogene Außenteile aufweisen, die beim Einschieben der Laschen formschlüssig mit Außenteilen des Flansches in Eingriff kommen.The present invention has for its object to provide a coil of the type mentioned above, which allows simple, machine-friendly manufacture. This is achieved in a simple manner in that the connections, designed as a tab, serve to mechanically hold the one side of the two diodes of a diode bridge which are soldered to the latter and which are arranged on opposite sides of the tab and are inserted as a unit in the form of the coil flange. In order to obtain winding points for the winding of the coil in a simple manner, it is advantageous if the other ends of the diodes protrude beyond the surface of the flange and serve as winding points for the winding. In order to simplify the soldering of the diodes to the tabs, it is advantageous if the tabs have insertion openings for the diode connecting wires exhibit. In order to keep the tabs securely in the bobbin when screwing on when screwing on the connecting wires, it is advantageous if the tabs are pushed into the grooves of the flange. For this purpose, it is also advantageous if the tabs have outer parts bent at right angles, which come into positive engagement with outer parts of the flange when the tabs are inserted.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben.

zeigt eine Explosionsdarstellung, wobei die Laschen noch nicht in den Spulenkörper eingefügt sind und
FIG 2
zeigt den komplettierten Spulenkörper,
FIG 3

An exemplary embodiment according to the invention is described with reference to the drawing.
FIG. 1
shows an exploded view, wherein the tabs are not yet inserted into the coil body and
FIG 2
shows the completed bobbin,
FIG 3
a connection diagram for the diode connection.

In FIG 1 sind die vorgefertigten Spulenanschlüsse 1 außerhalb des Spulenkörpers dargestellt. Sie bestehen aus den Laschen 2, die einerseits die Anschlußschrauben 3 mit den Klemmscheiben 4 aufnehmen und andererseits mit den einen Enden 5 der Dioden 20 verlötet sind. Hierzu sind in den Laschen 2 Einstecköffnungen für die Enden 5 vorgesehen, in die diese Enden vor dem Verlöten mit der Lasche eingeschoben werden können. Die so vorgefertigten Spulenanschlüsse 1 werden in Ausformungen 6 im Flansch 7 des Spulenkörpers 8 eingelegt. Nuten 9 dienen zur besseren Halterung der Laschen im Spulenkörperflansch. Rechtwinklig abgebogene Außenteile 11 der Laschen 2 umgreifen nach dem Einschieben in die Nuten 9 mit gabelförmigen Vorsprüngen 12 Ansätze 13 an der Außenseite des Flansches 7, so daß eine formschlüssige Halterung erreicht wird. Die anderen Enden 10 der Dioden ragen - wie die FIG 2 zeigt, über die Fläche des Spulenflansches hinaus. Sie sind mit Anschlüssen einer der Überspannungsbegrenzung dienenden Zenerdiode 14 verbunden und sie dienen weiterhin als Anwickelstifte für die Wicklung der Spule. Die elektrische Verbindung der Brückengleichrichter zwischen den Punkten 15, 16 bzw. 17, 18 - wie in FIG 3 - dargelegt - erfolgt über den Wickeldraht 19. Der Wickelanfang liegt bei 15 in FIG 2 am rechten oberen Ende 10 und wird durch eine Windung im Spulenkörper zum Punkt 16, das ist das linke obere Ende 10, geführt und zur weiteren Wicklung der Spule geführt. Mit dem Wickelende werden die Punkte 17 und 18, d.h. das linke und rechte untere Ende 10 über eine Windung wie am Anfang verbunden. Die Punkte 21, 22 - das sind die Laschen 2 - bilden die eigentlichen Spulenanschlüsse. Da die komplettierte Spule in das Gehäuse des elektromagnetischen Schaltgerätes eingelegt wird, kann auf ein Vergießen der Elemente im Spulenflansch verzichtet werden.1 shows the prefabricated coil connections 1 outside the coil body. They consist of the tabs 2, which on the one hand hold the connecting screws 3 with the clamping disks 4 and on the other hand are soldered to one end 5 of the diode 20. For this purpose, two insertion openings are provided in the tabs for the ends 5, into which these ends can be inserted before the tab is soldered. The coil connections 1 prefabricated in this way are inserted into formations 6 in the flange 7 of the coil body 8. Grooves 9 serve to better hold the tabs in the bobbin flange. Right-angled outer parts 11 of the tabs 2 grip after insertion into the grooves 9 with fork-shaped projections 12 lugs 13 on the outside of the flange 7, so that a positive locking is achieved. The other ends 10 of the diodes protrude - as shown in FIG 2 - beyond the surface of the coil flange. They are connected to connections of a Zener diode 14 which serves to limit the overvoltage, and they continue to serve as winding pins for winding the coil. The electrical connection of the bridge rectifier between the points 15, 16 or 17, 18 - as shown in FIG. 3 - takes place via the winding wire 19. The winding start is at 15 in FIG. 2 at the upper right end 10 and is turned to point 16 by a turn in the coil former, that is the left one upper end 10, guided and led to further winding of the coil. Points 17 and 18, ie the left and right lower ends 10, are connected to the end of the winding by means of a turn as at the beginning. Points 21, 22 - these are tabs 2 - form the actual coil connections. Since the completed coil is inserted into the housing of the electromagnetic switching device, the elements in the coil flange can be dispensed with.

Die erfindungsgemäße Anordnung eignet sich insbesondere für eine Automatenfertigung. Anstelle der Schraubanschlüsse können die Laschen auch als Steckanschlüsse ausgebildet werden, wie auch die linken Seiten der FIG 1 und 2 zeigen.The arrangement according to the invention is particularly suitable for machine production. Instead of the screw connections, the tabs can also be designed as plug connections, as is also shown on the left sides of FIGS. 1 and 2.
