Description

]sei elektromagnetisch betätigten Schaltgeräten ist es erwünscht, daß die Zugspule des Schaltmagneten leicht auswechselbar ist. Liese Forderung läßt sich bei den üblichen, die beweglichen Kontaktstücke unmittelbar betätigenden Klappankerntagneten in. 1>ekactnter Weise dadurch leicht verwirklichen, daß der .=Ankeranschlag gelöst und der Anker so weit zurückgeklappt wird, bis die Zugspule nach vorn abgezogen werden kann. Diese einfache Auswechselbarkeit lädt sich ohne weiteres nicht mehr vorsehen, sobald es sich um einen Schaltmagneten handelt, dessen Anker die die beweglichen Schaltstücke tragende Schaltbrücke über einen Kniehebel betätigt. Im allgemeinen ist mindestens eine Lagerstelle durch Entfernen des Lagerbolzens zu lösen. Meist ist jedoch weder die Lagerstelle des Kniehebels am Anker noch diejenige an der Schaltbrücke leicht zugänglich. In solchem Fall besteht somit die Aufgabe, eine Lagerung zu finden, die einerseits in jedem Fall ein Herausspringen des zu lagernden Betätigungselementes verhindert, die aber andererseits die Trennung von Kniehebel und Magnetanker bzw. Brücke ermöglicht, ohne daß ein Eingriff in die Lagerstelle erforderlich ist.] With electromagnetically operated switching devices, it is desirable that the pull coil of the solenoid is easily replaceable. Liese demand leaves with the usual hinged armature magnets that directly actuate the movable contact pieces in. 1> ekactnter way easy to realize that the. = anchor stop released and the armature is folded back so far that the pull spool is withdrawn to the front can be. This simple interchangeability no longer loads easily as soon as it is a switching magnet, the armature of which is the moving one Switching bridge carrying switch pieces operated via a toggle lever. In general at least one bearing point must be loosened by removing the bearing pin. Most of time however, it is neither the bearing point of the toggle lever on the armature nor that on the switching bridge easily accessible. In such a case, the task is to find a storage On the one hand, in any case, the actuating element to be stored jumping out prevents, on the other hand, the separation of toggle lever and magnet armature or Bridge allows without intervention in the bearing is required.

Die genannte Aufgabe wird durch den den Gegenstand des Patents bildenden und in der Abbildung dargestellten Schaltmagneten mit Kniehebelübersetzung in einfacher Weise gelöst. Der in den Deckblechen t des Nla--netelt 2 im Drehpunkt 3 gelagerte Klappanker 4, betätigt über den durch den Stützhebel 5 gelenkten Kniehebel 6 die vertikal geführte und die nicht gezeichneten beweglichen Schaltstücke tragende Schaltbrücke 7. Der Anschlag 8 begrenzt den Hub des Ankers 4. Die Lagerstellen 3, 9, i sind als unlösbar vorgesehen. Die im Anker ,4 befindliche offene Lagerstelle t i für den Hebel 6 ist dagegen als Tasche ausgebildet, die derart gestaltet ist, daß der Hebel 6 in keiner der durch Polfläche des Kernes 2 und Anschlag 8 begrenzten Ankerlagen aus dieser Lagertasche entfernt werden kann. Erst nach Entfernen des Anschlages 8 gibt die Lagertasche i i beim Weiterdrehen des Ankers 4 den Hebel 6 frei, und die Zugspule läßt sich in bekannter Weise auswechseln.The stated task is accomplished by the subject matter of the patent and switching solenoids shown in the figure with toggle lever transmission in simple Way solved. The one mounted in the cover plates t of the plane net 2 at the pivot point 3 Hinged armature 4, operated via the toggle lever 6 steered by the support lever 5, the vertically guided switching bridge carrying the movable contact pieces (not shown) 7. The stop 8 limits the stroke of the armature 4. The bearings 3, 9, i are as inextricably intended. The open bearing located in the anchor, 4 t i for the Lever 6, however, is designed as a pocket which is designed in such a way that the lever 6 in none of the armature positions delimited by the pole face of the core 2 and the stop 8 can be removed from this storage bag. Only after removing the stop 8, the bearing pocket i i releases the lever 6 when the armature 4 continues to rotate, and the pull spool can be changed in a known manner.
