Description

Die Erfindung bezieht sich auf ein elektromagnetisches Schaltgerät mit einem Magnetantrieb mit einem feststehenden Magnetkern und einem beweglichen Anker, der in einer Ankeraufnahme gehaltert ist, die mit einem die Ankerbewegung übertragenden Hebel, wie einer Schaltwippe, fest verbunden ist.The invention relates to an electromagnetic switching device with a Magnetic drive with a fixed magnetic core and a movable one Anchor, which is held in an anchor receptacle, the one with the anchor movement transmitting lever, such as a rocker switch, is firmly connected.

Für die Halterung des Ankers insbesondere unter Berücksichtigung der Dämpfung des Anker-Magnetkemstoßes sind verschiedene Möglichkeiten der Ankerhalterung bekannt. Aus der DE 34 43 555 C2 ist beispielsweise ein elektromagnetisches Schaltgerät bekannt, bei dem der Anker starr an einem die Ankerbewegung übertragenden Hebel befestigt ist, wobei keine zusätzlichen Mittel zur Dämpfung des Ankers vorgesehen sind. Ein solcher ungedämpfter Anker führt zu harten Anker-Magnetkernstößen. Darüber hinaus ist eine nachträgliche Justierung des montierten Ankers zwecks Hubkorrektur nicht möglich.For holding the anchor, especially taking into account the Damping the armature magnetic core shock are different ways of Anchor bracket known. DE 34 43 555 C2, for example, is an electromagnetic one Switching device known in which the armature is rigidly attached to the Armature transmitting lever is attached, with no additional Means for damping the armature are provided. Such an undamped Anchor leads to hard anchor magnetic core impacts. In addition, is an ex post Adjustment of the assembled anchor for stroke correction not possible.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Schaltgerät der eingangs genannten Art eine verbesserte Dämpfung des Ankers zur Dämpfung des Ankerkemstoßes zu schaffen und gleichzeitig eine Justierungsmöglichkeit, d.h. eine Hubkorrektur, für den befestigten Anker zu schaffen.The invention has for its object in a switching device of the beginning mentioned type an improved damping of the armature to dampen the To create an anchor shock and at the same time an adjustment option, i.e. to create a stroke correction for the attached anchor.

Diese Aufgabe wird bei einem gattungsgemäßen Schaltgerät gemäß dem Vorschlag der Erfindung dadurch gelöst, daß die Ankeraufnahme auf ihrer der Schaltwippe zugewandten Oberseite eine parallel zur Längsachse des an der Unterseite der Ankeraufnahme angeordneten Ankers ausgebildete Lagerbohrung zum Einsetzen eines an beiden Seiten mit einem Ende über die Lagerbohrung vorstehenden Bolzens aufweist, mit dem die Ankeraufnahme mit dem Anker an dem zugeordneten Aufnahmebereich der Schaltwippe mittels Schrauben befestigbar ist und an den Enden des Bolzens außerhalb der Längsachse des Bolzens parallel zur Längsachse desselben verlaufende Auflageflächen für die Verschraubung ausgebildet sind.This object is achieved in a generic switching device according to the proposal solved the invention in that the anchor receptacle on the Shift rocker facing top one parallel to the longitudinal axis of the Bottom of the anchor receptacle arranged anchor formed bearing bore for inserting one end on both sides over the bearing bore protruding bolt with which the anchor receptacle with the Anchor at the assigned receiving area of the rocker switch by means of Screws can be attached and at the ends of the bolt outside of the Longitudinal axis of the bolt running parallel to the longitudinal axis of the same are designed for the screw connection.

Erfindungsgemäß wird ein sehr einfacher Hubausgleich oder Hubkorrektur und Justiermöglichkeit hierfür dadurch geschaffen, daß die Bolzen, die die Ankeraufnahme und den Anker tragen, eine außerhalb der Längsachse des Bolzens liegende Aufnahmefläche aufweisen, die je nach Bedarf mit Justierplättchen entsprechender Dicke aufstockbar ist. Der Bolzen, der die Ankeraufnahme und Anker trägt, wird direkt mit der Wippe in einem Wippenaufnahmebereich verschraubt. Die planen Auflageflächen des Bolzens werden hierbei zum Hubausgleich mit Justierplättchen unterlegt. So ist es möglich, bei der Ankerbefestigung den Luftspalt in bezug auf den Magnetkern genau auf vorbestimmte Werte einzustellen. Unter Hubausgleich wird hier der Luftspalt zwischen Anker und Magnetkern verstanden. Eine andere Methode des Hubausgleiches ist der Einsatz jeweils von Bolzen verschiedener Dickenabmessungen an den Auflageflächen, die für die Befestigung der Ankeraufnahme an der Schaltwippe dienen.According to the invention, a very simple stroke compensation or stroke correction and Adjustment possibility created for this in that the bolts that hold the anchor and carry the anchor, one outside the longitudinal axis of the bolt have horizontal mounting surface, which can be adjusted with adjustment plates as required appropriate thickness can be increased. The bolt that holds the anchor and Anchor is screwed directly to the seesaw in a seesaw mounting area. The flat contact surfaces of the pin are used to compensate for the stroke underlaid with adjustment plate. So it is possible with the anchor attachment the air gap with respect to the magnetic core precisely to predetermined ones Set values. The air gap between the anchors is compensated for by the stroke and understood the magnetic core. Another method of stroke compensation is that Use of bolts of different thickness dimensions on the contact surfaces, the one for attaching the anchor bracket to the rocker switch serve.

Eine ausreichende Dämpfung des Anker-Magnetkernstoßes wird gemäß dem Vorschlag der Erfindung dadurch erreicht, daß auf der Oberseite der Ankeraufnahme mittig seitlich des Bolzens plattenförmige Dämpfungselemente aufgebracht sind. Für eine Vorfixierung der Dämpfungselemente auf der Ankeraufnahme wird vorgeschlagen, daß entsprechende Taschen zum teilweisen Einlegen der Dämpfungselemente auf der Oberseite der Ankeraufnahme ausgebildet sind. Je nach gewünschter Dämpfung können entweder entsprechend dicke plattenförmige Dämpfungselemente eingelegt werden oder mehrere Dämpfungselemente einer vorgegebenen Dicke.Adequate damping of the armature magnetic core shock is according to the Proposal of the invention achieved in that on the top of the anchor receptacle Plate-shaped damping elements applied in the center of the side of the bolt are. For pre-fixing the damping elements on the anchor holder it is suggested that appropriate bags for partial Inserting the damping elements formed on the top of the anchor receptacle are. Depending on the desired damping, you can either thick plate-shaped damping elements are inserted or more Damping elements of a predetermined thickness.

Erfindungsgemäß ist vorgesehen, den Anker mit der Ankeraufnahme und dem Bolzen zu einer einheitlichen Baugruppe zusammenzufassen, die als Einheit montierbar und demontierbar ist. Hierzu wird vorgeschlagen, daß der Anker mittels Bügel an der Ankeraufnahme eingehängt, wobei die Bügel mit einem Ende in eine Einhängenut an der Unterseite des Ankers eingehängt sind und mit ihrem anderen Ende die Ankeraufnahme oberseitig übergreifen und hier mittels einer Schraube befestigt sind.According to the invention it is provided that the anchor with the anchor receptacle and Combine bolts into a single assembly, which is a unit can be assembled and disassembled.

Die erfindungsgemäße Anordnung eines gedämpften Ankers mit zusätzlicher Justierbarkeit, d.h. der Möglichkeit eines Hubausgleiches ist als Baugruppe in einem elektromagnetischen Schaltgerät an einer Schaltwippe von unten montierbar und auch wieder demontierbar. Wenn beispielsweise bei elektromagnetischen Schaltgeräten mit Vakuumschaltröhren ein solcher Röhrensatz im Schienenträger ausgewechselt werden muß, so kann die Ankerbaugruppe insgesamt demontiert werden und nach Austausch des Vakuumröhrensatzes wiederum montiert werden und im Einsatz bleiben. Eine genaue Justierung des Luftspaltes ist mittels der Justierplättchen wiederum möglich.The arrangement of a damped anchor according to the invention with additional Adjustability, i.e. The possibility of stroke compensation is in as an assembly an electromagnetic switchgear can be mounted on a rocker switch from below and also removable.
