Description

Die vorliegende Erfindung betrifft eine Hilfsschalteranordnung mit mindestens zwei in einem Gehäuse befestigten Festkontaktstücken und mit mindestens einer mit den Festkontaktstücken durch Verschiebung eines mit linearen Nocken versehenen, durch ein Schaltgerät betätigbaren Schiebers in und ausser Eingriff bringbaren, in Schliessrichtung federbelasteten Kontaktbrücke, die in der Trennstellung durch die Nocken des Schiebers von den Festkontaktstücken abgehoben ist.The present invention relates to an auxiliary switch arrangement with at least two fixed contact pieces fastened in a housing and with at least one with the fixed contact pieces by moving one with linear cams provided, operated by a switching device slide in and out of engagement bringable, in the closing direction spring-loaded contact bridge, which is in the disconnected position lifted off the fixed contact pieces by the cams of the slide is.

Aus der europäischen Patentschrift, EP-B1-0347999 ist eine Hilfschalteranordnung der eingangs erwähnten Art bekannt. Bei dieser Hilfsschalteranordnung sind mindestens zwei Festkontaktstücke in einem Gehäuse angeordnet. Jeweils zwei Festkontaktstücke werden dabei durch eine bewegliche Kontaktbrücke in der Einschaltstellung miteinander verbunden. Die Kontaktbrücke ist als Balken am einen Ende eines T-förmigen, mit dem Anderen Ende im Gehäuse schwenkbar gelagerten Schwenkhebels angebracht. Der Schwenkhebel ist in Schliessrichtung der Kontaktstücke durch eine Schraubenfeder federbelastet. Im Gehäuse ist ein mit linearen Nocken versehener Schieber verschiebbar gelagert. Der Schieber wird in der Regel an einem elektrischen Schaltgerät angekoppelt und mit den beweglichen Kontaktstücken des Schaltgerätes mitbewegt. Die am Schieber vorhandenen linearen Nocken greifen an den Schwenkhebeln an und bewegen diese mit den Kontaktbrücken gegen die Federwirkung. In der Ausschaltstellung des Hilfsschalters heben die Nocken die Kontaktbrücken von den Festkontaktstücken ab. In der Einschaltstellung bringt die Schraubenfeder den Kontaktdruck auf die Kontaktbrücke auf. Ein erster Nachteil dieser Hilfsschalteranordnung besteht darin, dass der Schwenkhebel im Gehäuse schwenkbar gelagert werden muss, was mit der Ausbildung von Lagerstellen verbunden ist. Die Montage der Schwenkhebel in Verbindung mit der Schraubenfeder sind für eine automatische Montage nicht geeignet. In einer weiteren, ähnlich aufgebauten Hilfsschalteranordnung nach der Patentschrift, US-A-3016440 erhöht eine zusätzliche Druckfeder die Teilenzahl, den Montageaufwand und die Betätigungskraft, die von den Betätigungsorganen des elektrischen Schaltgerätes aufgebracht werden muss. Ausserdem kann es zu Anpassungsproblemen bei der Kopplung an unterschiedliche Schaltgeräte mit verschiedenen Hüben kommen. From the European patent specification, EP-B1-0347999 is an auxiliary switch arrangement of the type mentioned above. With this auxiliary switch arrangement at least two fixed contact pieces are arranged in a housing. Each two fixed contact pieces are connected by a movable contact bridge connected to each other in the switch-on position. The contact bridge is as a bar at one end of a T-shaped, with the other end pivotable in the housing mounted pivot lever attached. The swivel lever is in the closing direction the contact pieces are spring-loaded by a coil spring. In the housing is a slider provided with linear cams slidably mounted. The slide is usually coupled to an electrical switching device and moved with the movable contact pieces of the switching device. The most Linear cams of sliders engage the swivel levers and move them with the contact bridges against the spring action. In the off position of the auxiliary switch, the cams lift the contact bridges from the Fixed contact pieces. In the on position, the coil spring brings the Contact pressure on the contact bridge. A first disadvantage of this auxiliary switch arrangement is that the pivot lever in the housing can be pivoted must be stored, which is associated with the formation of storage locations. The assembly of the swivel levers in connection with the coil spring are for automatic assembly is not suitable. In another, similar one Auxiliary switch assembly according to the patent, US-A-3016440 increases one additional compression spring the number of parts, the assembly effort and the actuation force, applied by the actuators of the electrical switching device must become. In addition, there may be adjustment problems with the Coupling to different switchgear come with different strokes.

Aus der US-A-3675168 ist ein Schaltgerät mit einem in einem Gehäuse untergebrachten Festkontaktstück und mit einem am einen Ende eines U-förmig gegebogenen Blattfederbandes angebrachten beweglichen Kontaktstück bekannt. Das andere, freie Ende des Blattfederbandes ist am Gehäuse befestigt und dient als elektrische Anschlusstelle. Das am einen Ende des Blattfederbandes liegende bewegliche Kontaktstück wird durch einen Schieber über einen von der Kontaktstelle entfernten Nockenanordnung mit dem Festkontaktstück in und ausser Eingriff gebracht. Insbesondere bei Ueberstrom können die zwischen den parallelen Teilen des U-förmigen Blattfederbandes auftretenden elektrodynamischen Kräfte zu Schwingungen und als Folge zu Kontakttrennungen führen. Ausserdem wird das stromführende U-förmige Blattfederband durch den durchfliessenden Stom geheizt, was insbesondere bei Ueberströmen zu Beeinflussung der Federcharakteristik des Blattfederbandes führen kann.From US-A-3675168 is a switching device with a housed in a housing Fixed contact piece and with one bent at one end of a U-shape Leaf spring band attached movable contact piece known. The other, free end of the leaf spring band is attached to the housing and serves as an electrical connection point. The one lying at one end of the leaf spring band Movable contact piece is moved by a slide via one of the contact point removed cam arrangement with the fixed contact piece in and out Brought in. In the event of overcurrent in particular, those between the parallel Parts of the U-shaped leaf spring band occurring electrodynamic Forces cause vibrations and, as a result, contact separation. Furthermore is the current-carrying U-shaped leaf spring band through the flowing Electrically heated, which affects the spring characteristic, particularly in the case of overcurrents of the leaf spring band can lead.

Aufgabe der vorliegenden Erfindung ist es, eine Hilfsschalteranordnung zu schaffen, die verhältnismässig wenige Einzelteile aufweist, für eine automatische Montage geeignet und somit wirtschaftlich vorteilhaft ist und bei allen vorkommanden Strombelastungen ihre Funktionstüchtigkeit beibehält.The object of the present invention is to provide an auxiliary switch arrangement create that has relatively few items for an automatic Installation is suitable and therefore economically advantageous and for all existing electrical loads maintain their functionality.

Die gestellte Aufgabe ist dadurch gelöst, dass die Kontaktbrücke am einen Ende eines U-förmig gebogenen Blattfederbandes quer zur Längsrichtung des Blattfederbandes einstückig angeformt und das andere, freie Ende des U-förmig gebogenen Blattfederbandes im Gehäuse befestigt ist, wobei das Blattfederband in kontaktgebender Schliesstellung der Kontaktbrücke um den Betrag des Kontaktdruckes vorgespannt ist. Bei dieser Anordnung besteht die bewegliche Kontaktbrücke und das den Kontaktdruck für die beweglichen Kontaktstücke aufbringende Blattfederband aus einem einzigen Stück, das am Gehäuse befestigt ist. Diese Anordnung ist für eine automatische Montage geeignet und wirtschaftlich vorteilhaft. Dadurch, dass das Blattfederband nicht stromführend ist, beeinflusst der durch den Hilfsschalter geführte Strom die Eigenschaften der Hilfsschalteranordnung nicht.The task is solved in that the contact bridge at one end a U-shaped leaf spring band transverse to the longitudinal direction of the leaf spring band molded in one piece and the other, free end of the U-shaped curved leaf spring band is fixed in the housing, the leaf spring band in the contacting closing position of the contact bridge by the amount of the contact pressure is biased. With this arrangement there is the movable one Contact bridge and that the contact pressure for the moving contact pieces One-piece leaf spring band attached to the case is. This arrangement is suitable for automatic assembly and economically advantageous. The fact that the leaf spring band is not live the current passed through the auxiliary switch affects the properties the auxiliary switch arrangement is not.

Das Blattfederband ragt vorteilhafterweise zwischen den beiden auf den beiden Endbereichen der Kontaktbrücke angebrachten beweglichen Kontaktstücken über die Kontaktbrücke hinaus, wobei der überragende Teil zu einem mit den Nocken des Schiebers zusammenwirkenden Gleitbügel geformt ist. Der aus dem Material des Blattfederbandes geformte Gleitbügel vervollständigt die Funktionen des einstückigen Blattfederbandes. The leaf spring band advantageously projects between the two on the two End areas of the contact bridge attached movable contact pieces the contact bridge, with the protruding part becoming one with the cams the slide interacting slide bracket is shaped. The one from the material The leaf spring band shaped slide bracket completes the functions of the one-piece leaf spring band.

Mit Vorteil sind mehrere Kontaktbrücken und ein gemeinsamer Schieber mit mehreren zu jeder Kontaktbrücke zugeordneten Nocken vorgesehen. Mit mehreren Kontaktbrücken und mit einem mit entsprechend angeordneten Nocken versehenen Schieber können nach Bedarf beliebige Oeffner- und/oder Schliesskontakte zur Verfügung gestellt werden.It is advantageous to have several contact bridges and a common slide several cams assigned to each contact bridge are provided.
