Description

Die Erfindung betrifft einen Hilfskontaktblock zur Erweiterung eines Schaltgerätes sowie ein Schaltgerät mit zumindest einem erfindungsgemäßen Hilfskontaktblock.The invention relates to an auxiliary contact block for expanding a switching device and a switching device with at least one auxiliary contact block according to the invention.

Dabei ist ein Schaltgerät im Sinne der Erfindung ein elektromechanisches Schaltgerät oder Schaltgerätekombinationen mit elektronischem Überlastschutz, wie z.B. elektronische Leistungsschalter, Leitungsschutzschalter oder Schütze in Kombination mit elektronischem Überlastrelais, mit einer oder mehreren Strombahnen und mit einer oder mehreren Schaltstellen (typischerweise pro Strombahn).In this case, a switching device according to the invention is an electromechanical switching device or switchgear assemblies with electronic overload protection, such. electronic circuit breakers, circuit breakers or contactors in combination with electronic overload relays, with one or more current paths and with one or more switching points (typically per current path).

Üblicherweise können Schaltgeräte mit einem oder mehreren Hilfskontaktblöcken erweitert werden, die an das Schaltgerät an ein Gehäuse oder Gehäuseteil anbaubar oder bereits in das Gerät integriert sind. Die Hilfskontakte dienen dabei einer bestimmten Funktion, z.B. als Übermittlung des Status der Hauptkontaktpole. Bei Leistungsschaltern wird dadurch der Ein-, Aus- oder der Auslösezustand des Gerätes angezeigt.Typically, switching devices can be extended with one or more auxiliary contact blocks that can be attached to the switching device to a housing or housing part or already integrated into the device. The auxiliary contacts serve a specific function, e.g. as transmission of the status of the main contact poles. For circuit breakers, this indicates the on, off or trip status of the device.

Um die Betätigung der Hilfskontakt zu ermöglichen, werden Betätigungseinheiten eingesetzt. Diese werden bei Schützen z.B. mit elektromagnetischen Antrieben betätigt, bei Leistungsschaltern geschieht dies z.B. mit mechanischen Steuereinheiten (Sclialtschlössern). Die Betätigung der mechanischen Steuervorrichtung oder des elektromagnetischen Antriebes bewirkt eine Schließung oder Öffnung der Kontakte, die über die Betätigungseinheiten mit der mechanischen Steuereinheit oder dem Elektromagneten verbunden sind. Da heutzutage mehr und mehr der Trend zu kleinbauenden beispielsweise Motorstärtervorrichtungen geht - entsprechend einer der oben genannten Schaltgerätekombinationen - werden Hilfskontakte in passender Form benötigt, da bei bekannten Hilfskontaktblöcken, bei denen beispielsweise externe Hilfskontakte auf unterschiedliche Ebenen auf das Schaltgerät angebaut werden, der Verdrahtungsaufwand und der Platzbedarf hoch sind.Actuator units are used to enable actuation of the auxiliary contact. These are actuated by contactors, eg with electromagnetic drives, with circuit breakers this is done, for example, with mechanical control units (slave locks). The actuation of the mechanical control device or the electromagnetic drive causes a closure or opening of the contacts, which are connected via the actuating units with the mechanical control unit or the electromagnet. As nowadays more and more the trend is towards small-sized, for example, motor power devices - according to one of the above-mentioned switchgear assemblies - auxiliary contacts are required in an appropriate form, as in known auxiliary contact blocks, in which For example, external auxiliary contacts are mounted on different levels on the switching device, the wiring and space requirements are high.

Hilfskontaktblöcke zur Erweiterung eines Schaltgerätes mit in einer Ebene angeordnete Hilfskontakten mit Kontaktbrücken und dazugehörigen Festschaltstücken sowie mit zumindest einem Kontaktschieber, der mit zumindest einem Hilfskontaktpaar bestückbar ist, wobei der Kontaktschieber mittels einer Betätigungseinheit betätigbar ist, die mit zumindest einer Schaltvorrichtung zum Schalten der zumindest einen Schaltstelle verbindbar ist sind aus den DE 196 36 109 C1 , WO 2005/101444 A , DE 101 18919 A1 , sowie aus der DE 875 681 B . Weitere Kontaktvorrichtungen sind außerdem aus den DE 22 19 428 C2 , DE 102 96 272 T5 sowie aus der DE 10 2004 034 859 A1 bekannt.Auxiliary contact blocks for extending a switching device arranged in a plane auxiliary contacts with contact bridges and associated Festschaltstücken and with at least one contact slide which can be equipped with at least one pair of auxiliary contact, wherein the contact slide is actuated by means of an actuating unit with at least one switching device for switching the at least one switching point connectable are from the DE 196 36 109 C1 . WO 2005/101444 A . DE 101 18919 A1 , as well as from the DE 875 681 B , Other contact devices are also from the DE 22 19 428 C2 . DE 102 96 272 T5 as well as from the DE 10 2004 034 859 A1 known.

Der Erfindung liegt die Aufgabe zugrunde, einen kompakten Hilfskontaktblock, d.h. mit geringem Verdrahtungsaufwand und Platzbedarf, für ein Schaltgerät sowie ein Schaltgerät mit zumindest einem erfindungsgemäßen Hilfskontaktblock anzugeben.The invention has for its object to provide a compact auxiliary contact block, i. specify with little wiring and space requirements, for a switching device and a switching device with at least one auxiliary contact block according to the invention.

Diese Aufgabe wird durch einen Hilfskontaktblock zur Erweitering eines Schaltgerätes mit zumindest einer Strombahn und mit zumindest einer Schaltstelle, wobei der Hilfskontaktblock in einer Ebene angeordnete Hilfskontakte mit Kontaktbrücken und zugehörige Festschaltstücke sowie zumindest einen Kontaktschieber aufweist, der mit zumindest einem Hilfskontaktpaar bestückbar ist, wobei der Kontaktschieber mittels einer Betätigungseinheit betätigbar ist, die mit zumindest einer Schaltvorrichtung zum Schalten der zumindest einen Schaltstelle verbindbar ist, gelöst, wenn die Ebene, in der die Hilfskontakte angeordnet sind, in einer senkrechten Anordnung zu einer Betätigungsrichtung der zumindest einen Schaltstelle vorgesehen ist.This object is achieved by an auxiliary contact block for extending a switching device with at least one current path and at least one switching point, wherein the auxiliary contact block arranged in a plane auxiliary contacts with contact bridges and associated Festschaltstücke and at least one contact slide, which can be equipped with at least one auxiliary contact pair, wherein the contact slide can be actuated by means of an actuating unit, which is connectable to at least one switching device for switching the at least one switching point, solved when the plane in which the auxiliary contacts are arranged, is provided in a vertical arrangement to an actuating direction of the at least one switching point.

Alternativ ist es möglich, Biegelinien, um die herum die Festschaltstücke gebogen sind, im Wesentlichen senkrecht zu einer Befestigungsebene vorzusehen, mit der das Schaltgerät insbesondere an einer Hutschiene befestigbar ist. Diese (virtuellen) Biegelinien können gewissermaßen als Achsen von Zylindern betrachtet werden, um die während des Biegeprozesses die Festschaltstücke gebogen werden. Durch die im Wesentlichen senkrechte Anordnung der Biegelinien zur Befestigungsebene, mit der das Schaltgerät insbesondere an einer Hutschiene befestigbar ist, weisen die Festschaltstücke nur parallel zur Befestigungsebene Biegungen auf, wodurch auch die ausgangsseitigen Enden der Festschaltstücke im Wesentlichen senkrecht zur Befestigungsebene des Schaltgerätes stehen.Alternatively, it is possible to provide bending lines, around which the fixed contact pieces are bent, substantially perpendicular to a fastening plane with which the switching device can be fastened, in particular, to a DIN rail. These (virtual) bending lines can be considered, in a sense, as the axes of cylinders around which the fixed contact pieces are bent during the bending process. Due to the substantially vertical arrangement of the bending lines to the mounting plane with which the switching device is fastened in particular on a top hat rail, the fixed switching pieces only parallel to the mounting plane bends, whereby the output ends of the Festschaltstücke are substantially perpendicular to the mounting plane of the switching device.

Diese Aufgabe wird weiter durch ein Schaltgerät mit zumindest einer Strombahn, mit zumindest einer Schaltstelle, mit zumindest einer Schaltvorrichtung zum Schalten der zumindest einen Schaltstelle, mit zumindest einem Hilfskontaktblock nach einem der Ansprüche 1 bis 8 sowie mit einer Betätigungseinheit zur Betätigung des Kontaktschiebers gelöst.This object is further achieved by a switching device with at least one current path, with at least one switching point, with at least one switching device for switching the at least one switching point, with at least one auxiliary contact block according to one of claims 1 to 8 and with an actuating unit for actuating the contact slide.

Der hier beschrieben Aufbau der Hilfskontakte in einer Ebene ermöglicht auf einfache Weise ein sehr geringes Bauvolumen und einen sehr geringen Verdrahtungsaufwand der Hilfskontakte. Die Betätigungseinheit kann hierbei beispielsweise als schieber ausgeführt sein, der den Kontaktschieber und die Schaltvorrichtung miteinander koppelt.The structure of the auxiliary contacts in a plane described here allows in a simple way a very small volume and a very low wiring costs of the auxiliary contacts. The actuating unit can be designed, for example, as a slide, which couples the contact slide and the switching device together.

In einer vorteilhaften Ausführungsform weist zumindest ein Kontaktschieber zwei Schließerhilfskontakte auf, die über den Kontaktschieber und die zugehörige Betätigungseinheit mit der Schaltvorrichtung koppelbar sind, wobei die Schaltvorrichtung als mechanische Steuereinheit ausgeführt ist. Somit können die Hilfskontakte beispielsweise den Status eines Schaltschlosses, d.h. der mechanischen Steuereinheit, übermitteln.In an advantageous embodiment, at least one contact slide on two NO auxiliary contacts, which can be coupled via the contact slide and the associated actuator with the switching device, wherein the switching device is designed as a mechanical control unit. Thus, for example, the auxiliary contacts may have the status of a latching mechanism, i. the mechanical control unit, transmit.

In einer weiteren vorteilhaften Ausführungsform weist zumindest ein Kontaktschieber eine Öffner-Schließer-Kombination auf, die über den Kontaktschieber und die zugehörige Betätigungseinheit mit der Schaltvorrichtung koppelbar ist, wobei die Schaltvorrichtung als elektromagnetischer Antrieb ausgeführt ist. Somit können die Hilfskontakte beispielsweise den Status einer Schützfunktion, d.h. des elektromagnetischen Antriebs, übermitteln.In a further advantageous embodiment, at least one contact slide has an opener-closer combination on, which can be coupled via the contact slide and the associated operating unit with the switching device, wherein the switching device is designed as an electromagnetic drive. Thus, the auxiliary contacts, for example, the status of a contactor function, ie the electromagnetic drive, transmit.

In einer weiteren vorteilhaften Ausführungsform sind die Festschaltstücke spiegelbildlich in der Ebene angeordnet. Auf diese Weise kann die Teilevarianz reduziert werden, da hier identische Feststrombahnen verwendet werden können.In a further advantageous embodiment, the fixed switching pieces are arranged in mirror image in the plane. In this way, the parts variance can be reduced because identical solid-current paths can be used here.

In einer weiteren vorteilhaften-Ausführungsform sind für alle Hilfskontakte identische Kontaktbrücken vorgesehen, wodurch die Teilevarianz weiter reduziert werden kann.In a further advantageous embodiment, identical contact bridges are provided for all auxiliary contacts, whereby the part variance can be further reduced.

In einer weiteren vorteilhaften Ausführungsform sind die Festschaltstücke ausgangsseitig, derart ausgeführt, dass zumindest ein Klemmenblock anbaubar ist. Die Verwendung eines oder mehrerer geeigneter Klemmenblöcke gestattet es, nicht jeden Hilfskontakt einzeln anschließen zu müssen.In a further advantageous embodiment, the fixed switching pieces on the output side, designed such that at least one terminal block is attachable. The use of one or more suitable terminal blocks makes it impossible to connect each auxiliary contact individually.

In einer weiteren vorteilhaften Ausführungsform ist der Hilfskontaktblock in eine Magnetkammer des Schaltgerätes integrierbar. Somit werden keine einzelnen Gehäuse für den Hilfskontaktblock oder die einzelnen Hilfskontakte benötigt, wodurch sich der Platzbedarf weiter reduziert. Die Integration des Hilfskontaktblockes in das Schaltgerät resultiert dabei in einem besonders kompakten Bauteil.In a further advantageous embodiment, the auxiliary contact block can be integrated into a magnetic chamber of the switching device. Thus, no single housing for the auxiliary contact block or the individual auxiliary contacts are needed, which further reduces the space required. The integration of the auxiliary contact block in the switching device results in a particularly compact component.

In einer weiteren vorteilhaften Ausführungsform'ist die Ebene, in der die Hilfskontakte angeordnet sind, durch eine Wand in der Magnetkammer gebildet. Dies erleichtert u.a. die Montage des Hilfskontaktblockes in der Magnetkammer des Schaltgerätes.In a further advantageous embodiment, the plane in which the auxiliary contacts are arranged is formed by a wall in the magnet chamber. This facilitates, inter alia, the mounting of the auxiliary contact block in the magnetic chamber of the switching device.

FIG 1 zeigt eine Draufsicht auf ein Ausführungsbeispiel eines erfindungsgemäßen Hilfskontaktblocks 1, der beispielsweise für einen Motor- oder Kompaktabzweig verwendet werden kann. Die Kontaktschieber 7, 8 sind mit den Hilfskontakten 3, 4 bestückt und liegen parallel nebeneinander in einer Ebene. Die dazugehörigen Festschaltstücke 6 liegen in der gleichen Ebene wie die Hilfskontakte 3, 4. Der erste Kontaktschieber 7 wird durch zwei Schließer gebildet, die als Hilfskontakte 4 für eine mechanische Steuereinheit 9 (Schaltschloss, s. FIG 3) gedacht sind. Der zweite Schieber 8 ist eine Öffner-schließer-Kombination 11 und dient für die Schützfunktion des z.B. Kompaktabzweigs, d.h. er wird über eine Betätigungseinheit 15 an den elektromagnetischen Antrieb 10 des Schaltgerätes 2 (s. FIG 3) gekoppelt. Die genannten Hilfskontakte 3, 4 übernehmen dabei die oben erwähnten Funktionen wie Übermittlung des Status der Hauptkontakte und/oder Anzeige des Ein-, Aus- oder Auslösezustands des Gerätes 2. Der hier gezeigte Aufbau in einer Ebene ermöglicht auf einfache Weise ein sehr geringes Bauvolumen des Hilfskontaktblockes 1. Das Schließerhilfskontaktpaar 4 sowie die Öffner-Schließer-Kombination 11 benötigen keine einzelnen Gehäuse, sondern sind direkt in die Magnetkammer des z.B. Kompaktstarters integrierbar. Damit werden zusätzliche Gehäuseteile für Hilfskontaktblöcke 1 nicht benötigt. Da die Kontaktschieber 7, 8 spiegelbildlich in der Ebene angeordnet sind, kann zusätzlich die Teilevarianz reduziert werden. Hier können identische Feststrombahnen 6 verwendet werden, vgl. die beiden linken Festschaltstücke 6 mit den beiden rechten Festschaltstücken 6 in der Darstellung. Die Biegungen der Festschaltstücke 6 befinden sich dabei nur in der Ebene, in der die Hilfskontakte 3, 4 angeordnet sind, d.h. die Biegelinien, um die herum die Festschaltstücke gebogen sind, verlaufen senkrecht zu der Ebene. Des Weiteren sind für alle Hilfskontakte 3, 4 identische Kontaktbrücken 5 vorgesehen, was die benötigte Teilevarianz weiter reduziert. Da alle Ausgänge der Hilfskontakte 3, 4 auf einer Seite liegen, ergibt sich hier ein sehr geringer Verdrahtungsaufwand für die Hilfsschalter 3, 4 des z.B. Kompaktabzweiges. FIG. 1 shows a plan view of an embodiment of an auxiliary contact block 1 according to the invention, which can be used for example for a motor or compact branch. The contact slide 7, 8 are equipped with the auxiliary contacts 3, 4 and are parallel to each other in a plane. The associated fixed contact pieces 6 are in the same plane as the auxiliary contacts 3, 4. The first contact slide 7 is formed by two NO contacts, which are used as auxiliary contacts 4 for a mechanical control unit 9 (switch lock, s. FIG. 3 ) are meant. The second slide 8 is a normally closed normally closed combination 11 and serves for the contactor function of the eg compact branch, ie it is connected via an actuating unit 15 to the electromagnetic drive 10 of the switching device 2 (see FIG. FIG. 3 ) coupled. The aforementioned auxiliary contacts 3, 4 take over the above-mentioned functions such as transmission of the status of the main contacts and / or display of on, off or trip status of the device 2. The structure shown here in a plane allows in a simple way a very low volume of Auxiliary contact block 1. The NO auxiliary contact pair 4 and the NO / NC combination 11 do not require individual housings, but can be integrated directly into the magnet chamber of, for example, the compact starter. Thus, additional housing parts for auxiliary contact blocks 1 are not required. Since the contact slide 7, 8 are arranged in mirror image in the plane, in addition, the parts variance can be reduced. Here, identical solid-current paths 6 can be used, cf. the two left Festschaltstücke. 6 with the two right Festschaltstücken 6 in the illustration. The bends of the fixed contact pieces 6 are only in the plane in which the auxiliary contacts 3, 4 are arranged, that is, the bending lines around which the Festschaltstücke are bent, perpendicular to the plane. Furthermore, identical contact bridges 5 are provided for all auxiliary contacts 3, 4, which further reduces the required part variance. Since all outputs of the auxiliary contacts 3, 4 are on one side, this results in a very small wiring effort for the auxiliary switch 3, 4 of the example compact branch.

FIG 2 zeigt den Hilfskontaktblock 1 aus FIG 1 in einer perspektivischen Darstellung. Gut zu erkennen ist hier die Anordnung der Kontaktschieber 7, 8, der Hilfskontakte 3, 4 und der zugehörigen Festschaltstücke 6 in einer Ebene. Für eine Erläuterung der weiteren Bezugszeichen wird auf die Beschreibung zu Figur 1 verwiesen. FIG. 2 shows the auxiliary contact block 1 from FIG. 1 in a perspective view. Good to see here is the arrangement of the contact slide 7, 8, the auxiliary contacts 3, 4 and the associated Festschaltstücke 6 in a plane.
