Description

Die Erfindung betrifft einen elektromagnetischen Überstromschalter, insbesondere in Schraubstöpselform, bei dem ein von einem Tauchkern bewegter Schaltstab durch ein Federband in der Kontaktlage gehalten wird. Bei den bisher bekannten Schaltern dieser Art greift das Federband unmittelbar in die Aussparung eines fest mit dem Tauchkern verbundenen Teiles ein. Bei diesen SchalternThe invention relates to an electromagnetic overcurrent switch, in particular in Screw plug shape in which a switching rod moved by a plunger core passes through a Spring band is held in the contact position. With the previously known switches this Art grips the spring band directly into the recess of a firmly attached to the plunger core connected part. At these switches

ίο kann es vorkommen, daß der Schaltstab bei Zunahme der magnetischen Erregung langsam nach oben wandert. Dadurch wird die Kontaktgabe beeinträchtigt.
* Nach der Erfindung hat der Schaltstab einenίο it can happen that the switching rod slowly moves upwards when the magnetic excitation increases. This impairs the making of contact.
* According to the invention, the switch rod has a

ϊ5 hohlen Fortsatz, in dem sich ein besonderer Tauchkern befindet, und in dessen Wandung das Federband eingreift.ϊ5 hollow process in which there is a special Immersion core is located, and the spring band engages in its wall.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, ι ist der Schaltstab, 2 die Spule, 3 der Tauchkern und 4 das Federband mit dem Haltenocken 5. Der Haltenocken ist als Rolle ausgebildet. Der Schaltstab 1 hat ferner einen hohlen Fortsatz 6, in dessen Wandung der Haltenocken eingreift. 3 ist der in dem Fortsatz 6 untergebrachte Tauchkern. An dem Schaltstab sitzen ferner die Schaltkontakte 7. Der Haltenocken 5 reicht so weit in das Innere des hohlen Ansatzes 6 hinein, daß er durch den Tauchkern 3 zurückgedrängt wird, wenn dieser von der Spule angezogen wird.In the drawing, an embodiment of the invention is shown, ι is the Switching rod, 2 the coil, 3 the plunger and 4 the spring band with the retaining cam 5. The Retaining cam is designed as a role. The switching rod 1 also has a hollow extension 6, in the wall of which the retaining cam engages. 3 is the one accommodated in the extension 6 Diving core. The switch contacts 7 are also located on the switch rod 5 extends so far into the interior of the hollow extension 6 that it is pushed back by the plunger 3 when this is attracted to the coil.

Beim Ansprechen des Schalters hat der Tauchkern bereits eine gewisse Geschwindigkeit und Wucht, bevor er den Haltenocken 5 zurückdrängt und den Schaltstab nach oben bewegt. Dadurch wird die Sperrung mit Sicherheit schlagweise überwunden und ein schnelles Abschalten erzielt. Der Schalter hat ferner den Vorteil, daß der Haltenocken auch bei etwaigen Seitenbewegungen des Ansatzes 6 ihm folgen kann, daß diese Bewegung aber andererseits durch den Tauchkern 3 begrenzt wird. Die zwischen Tauchkern und Schaltstab befindliche Feder 8 dient dazu, den Tauchkern nach der Ausschaltung wieder in seine ursprüngliche Lage zurückzubringen.When the switch is triggered, the plunger has already reached a certain speed and force before it pushes the retaining cam 5 back and the switch rod upwards emotional. As a result, the blocking is surmounted suddenly and a quick shutdown is achieved. The switch has furthermore the advantage that the retaining cam also with any lateral movements of the shoulder 6 can follow it, but on the other hand this movement is limited by the plunger 3 will. The spring 8 located between the plunger core and the switch rod serves to hold the plunger core to return to its original position after being switched off.

An Stelle eines nur mechanisch wirkenden Federbandes kann auch ein federndes Heizband verwendet werden, das vom Strom durchflossen wird und sich bei stärkeren Belastungen durchbiegt und dadurch die Sperrung aufhebt. Bei starken, plötzlichen Belastungen wird es außerdem durch den angezogenen Anker 3 ausgeklinkt.Instead of a spring strip that only acts mechanically, a resilient heating strip can also be used which is traversed by the current and which can be used in the event of higher loads deflects and thereby removes the lock. With strong, sudden loads it will also notched by the tightened anchor 3.
