Description

Die vorliegende Erfindung betrifft ein elektromagnetisches Schaltgerät, insbesondere Schütz, mit mindestens einem bewegliche Kontaktstücke und damit zusammenwirkende ortsfeste Kontaktstücke enthaltenden Kontaktmodul, mit einem einen elektromagnetisch betätigbaren Anker aufweisenden Antriebsmodul und mit einer den Anker mit den beweglichen Kontaktstücken verbindenden, zwischen dem Kontaktmodul und dem Antriebsmodul angeordneten Ankopplungseinrichtung.The present invention relates to an electromagnetic switching device, in particular Contactor, with at least one movable contact pieces and thus cooperating stationary contact pieces containing contact module, with a drive module having an electromagnetically operable armature and with the armature connected to the movable contact pieces, between the contact module and the drive module arranged coupling device.

Aus der DE-A1-4236890 ist ein elektromagnetisches Schaltgerät der eingangs erwähnten Art bekannt. Bei diesem Schaltgerät ist das Antriebsmodul ein für sich abgeschlossenes Grundmodul. Auf dieses Grundmodul können mehrere Kontaktmodule aufgebaut werden, wobei die Breite der aufbaubaren Kontaktmodule immer einem Vielfachen der Modulbreite eines Hilfsschaltermodules entspricht und nicht über die Breite des Antriebsmoduls hinausgehen kann. Dies bedeutet, dass beispielsweise für ein vierpoliges Schütz ein Antriebsmodul mit der entsprechenden Breite gewählt werden muss. In der Regel werden aber elektromagnetische Schaltgeräte dreipolig gebaut, so dass die Mehrheit der Antriebsmodule in einem Betrieb nur für dreipolige Schaltgeräte verwendbar ist. Für vierpolige Schütze oder Schaltgeräte mit einem über die Breite des Antriebsmoduls hinausragenden Kontaktmodul ist ein anderes Antriebsmodul erforderlich, das wegen den kleineren Herstellungsserien mit wirtschaftlichen Nachteilen verbunden ist.From DE-A1-4236890 is an electromagnetic switching device of the beginning known type known. In this switching device, the drive module is a for self-contained basic module. Several contact modules can be connected to this basic module be built, the width of the modular contact modules always equal to a multiple of the module width of an auxiliary switch module and can not go beyond the width of the drive module. This means, that for example for a four-pole contactor, a drive module with the corresponding Width must be selected. As a rule, but electromagnetic Switchgear built three-pole, so that the majority of the drive modules in one operation only for three-pole switching devices is usable. For four-pole contactors or switching devices with one across the width of the drive module protruding contact module another drive module is required because of the smaller production series with economic disadvantages connected is.

Aus der US-A-4951018 ist ein weiteres elektromagnetisches Schaltgerät bekannt. Dieses Schaltgerät ist nicht für Modulbauweise vorgesehen und enthält ein Gehäuse zur Halterung des Elektromagneten und der Festkontaktstücke sowie zur Führung der im Gehäuse verschiebbare bewegliche Kontaktstücke tragenden Kontaktbrücke. From US-A-4951018 another electromagnetic switching device is known. This switching device is not intended for modular design and contains a housing for holding the electromagnet and the fixed contact pieces as well as for guiding the sliding contact pieces movable in the housing carrying contact bridge.

Aufgabe der vorliegenden Erfindung ist es, ein elektromagnetisches Schaltgerät, insbesondere ein Schütz zu entwickeln, bei welchem unabhängig von der Polzahl und unabhängig von der damit in der Regel zusammenhängenden grösseren Breite des Kontaktmoduls bei Beibehaltung aller Funktionen des Schützes ein einziges Antriebsmodul verwendbar ist und bei welchem die Anordnung wirtschaftlich vorteilhaft ist.The object of the present invention is to provide an electromagnetic switching device, In particular, to develop a contactor, in which regardless of the number of poles and regardless of the larger associated with it as a rule Width of the contact module while retaining all functions of the contactor single drive module is used and in which the arrangement economical is advantageous.

Die gestellte Aufgabe ist dadurch gelöst, dass auf ein Antriebsmodul ein im Vergleich mit dem Antriebsmodul überbreites, beidseitig über die Breite des Antriebsmoduls hinausragendes Kontaktmodul aufsetzbar ist, wobei die beiden Seitenwände des Kontaktmoduls auf die ganze Höhe des Antriebsmoduls verlängert und mit einer in Hubrichtung des Ankers ausgerichteten offenen Nut versehen sind und sowohl das Kontaktmodul als auch das Antriebsmodul umschliessen und die zwischen den Seitenwänden verschiebbare Ankopplungseinrichtung an ihren den beiden Seitenwänden zugekehrten Seiten mit in die offenen Nuten eingreifenden Mitnehmerzapfen versehen ist. Durch diese Massnahmen ist es möglich für alle praktisch vorkommenden elektromagnetischen Schaltgeräte ein in der Regel meistverwendetes Antriebsmodul zu verwenden. Nur das Kontaktmodul und die Ankopplungseinrichtung müssen der Polzahl des Schaltgerätes angepasst und speziell hergestellt werden. Dadurch, dass die beiden Seitenwände des Kontaktmoduls auf die ganze Höhe des Antriebsmoduls verlängert und mit einer in Hubrichtung des Ankers ausgerichteten offenen Nut versehen sind, ergibt sich sowohl eine gute Führung der mit ihren Mitnehmerzapfen in die offenen Nuten eingreifenden Ankopplungseinrichtung zwischen den Seitenwänden als auch ein vorteilhafter seitlicher Abschluss des zusammengesetzten Schaltgerätes.The stated object is achieved in that a drive module in the Compared with the drive module wide, on both sides across the width of the Drive module protruding contact module can be placed, the two Side walls of the contact module extended to the full height of the drive module and with an aligned in the stroke direction of the armature open groove are provided and enclose both the contact module and the drive module and the sliding between the side walls coupling device on their sides facing the sides with in the open grooves engaging driving pin is provided. Through these measures It is possible for all practically occurring electromagnetic Switching devices to use a usually used drive module. Only the contact module and the coupling device must the number of poles of Switching device adapted and specially manufactured. Because of that both side walls of the contact module on the entire height of the drive module extended and with an aligned in the stroke direction of the anchor open groove are provided, resulting in both a good leadership with their driving pin in the open grooves engaging coupling device between the Side walls as well as an advantageous lateral completion of the composite Switching device.

Besondere Vorteile sind erreichbar, wenn das auf ein für dreipolige Schaltgeräte bestimmtes Antriebsmodul aufgesetzte Kontaktmodul vierpolig ist, weil die grossen Serien der hergestellten Antriebsmodule für dreipolige Schütze vorgesehen sind.Special advantages are achievable, if that on one for three-pole switching devices certain drive module patch contact module is four-pole, because the large series of manufactured drive modules for three-pole contactors provided are.

Durch die offenen Nuten können das Betätigungsglied des Hilfsschalters und der Mitnehmerzapfen der Ankopplungseinrichtung des Schaltgerätes ineinandergreifen. Es ist keine besondere Ausführung des Hilfsschalters erforderlich, seine Befestigung und Betätigung ist gleich wie bei anderen Schützen.The drive pins present on the coupling device are advantageously for coupling the actuation of one to the adjacent one Side wall mounted auxiliary switch formed on the coupling device. Through the open grooves, the actuator of the auxiliary switch and the driving pin of the coupling device of the switching device interlock. No special version of the auxiliary switch is required its attachment and operation is the same as with other shooters.
