Abstract

A drive mechanism for electrical switches, especially built-in switches, having a rocker lever which is supported on the housing for operating a contact carrier which is supported in a sliding manner between the housing walls, in which a contact link is supported in a sprung manner and electrically connects the connecting contacts in the switched-on state. A switching cam 2A is integrally formed on the rocker lever 2 and slides in a force-fitting manner, during the switching process, along on the shoulder 3B of the contact carrier 3 (which is supported in a sliding manner in the housing and acts against the switching cam 2A by means of spring force), and at the same time controls said contact carrier 3, which acts like a claw. A driver 2B which acts like a claw is integrally formed or formed out on the switching cam 2A, engages behind the stop 3A (which is integrally formed on the contact carrier 3) in a positively locking manner and at the same time locks the rocker lever 2 in the region of the switched-on position. <IMAGE>

Description

Die Erfindung betrifft einen Antriebsmechanismus für elektrische Schalter, insbesondere Einbauschalter, gemäß dem Oberbegriff des Schutzanspruches 1.The invention relates to a drive mechanism for electrical Switches, especially built-in switches, according to the preamble of Protection claim 1.

Bei bekannten Ausführungen ist der Kipphebel des Schaltmechanis­ mus mit dem Kontaktträger entweder mittels einer Steckachse, wie aus der DE-OS 25 48 723 und DE-PS 29 01 246 ersichtlich, oder mittels eines Bügels, wie in der DE-OS 28 46 213 vorgeschlagen wird, verbunden.In known designs, the rocker arm of the switching mechanism mus with the contact carrier either by means of a thru axle, such as can be seen from DE-OS 25 48 723 and DE-PS 29 01 246, or by means of a bracket, as proposed in DE-OS 28 46 213 connecting.

Eine formschlüssige Verbindung ist bei diesen elektrischen Schaltern erforderlich, damit der Schaltzustand eindeutig für den Bedienenden erkennbar ist.A positive connection is in these electrical Switches required so that the switching status is clear for is recognizable to the operators.

Insbesondere beim Verschweißen der Schaltkontakte darf es nicht möglich sein, den Kipphebel in die Ausschaltstellung zu bringen, um zu verhindern, daß ein falscher und damit gefährlicher Schaltzustand angezeigt wird, z. B. bei Arbeiten unter Spannung, wenn die gesamte Anlage nicht abgeschaltet werden kann.Especially when welding the switch contacts, it must not be able to move the rocker arm to the off position, to prevent a wrong and therefore dangerous Switching status is displayed, e.g. B. when working under voltage, if the entire system cannot be switched off.

Aufgabe der Erfindung ist, den Antriebsmechanismus so auszubil­ den, daß auf die Einbringung eines Übertragungsteiles zwischen Kipphebel und Kontaktträger verzichtet werden kann, um die Mon­ tage zu vereinfachen und die Herstellkosten zu mindern.The object of the invention is to train the drive mechanism in this way the that on the introduction of a transmission part between Rocker arm and contact carrier can be omitted to the Mon simplify days and reduce manufacturing costs.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruches 2 gelöst.This object is achieved by the characterizing Features of the protection claim 2 solved.

In den Unteransprüchen der Erfindung wird eine konstruktive Aus­ gestaltung der Teile des Antriebsmechanismus vorgeschlagen, die keinen besonderen werkzeugtechnischen Aufwand erfordert.In the subclaims of the invention, a constructive design of the parts of the drive mechanism proposed that does not require any special tooling effort.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Abbildun­ gen erläutert.An embodiment of the invention is based on the figures gene explained.

Abb. 3 den Antriebsmechanismus in perspektivischer Darstellung in einer Position des Kipphebels, in der dieser mittels dem am Kontaktträger angeformten Anschlag arretiert wird. Fig. 3 shows the drive mechanism in a perspective view in a position of the rocker arm, in which this is locked by means of the molded stop on the contact carrier.

Der Antriebsmechanismus besteht aus dem Kipphebel 2, der im Schaltergehäuse 1 an der Welle 1 B schwenkbar gelagert ist. Dem Kontaktträger 3, der mit dem Kipphebel 2 in Wirkverbindung steht und im Schaltergehäuse 1 mittels der Kontaktträgerführung 1 A gleitend gelagert ist. Zwischen der Bodenwand 1 C des Schalterge­ häuses 1 und dem Kontaktträger 3 ist eine Druckfeder 6 ange­ ordnet, die als Kraftspeicher für die Rückstellung beim Aus­ schalten dient. Der Kontaktträger 3 ist mit der Kontaktbrücke 4 bestückt, deren Kontaktdruck durch die Druckfeder 7 erzeugt wird, die sich an der oberen Traverse 3 C des Kontaktträgers 3 abstützt.The drive mechanism consists of the rocker arm 2 , which is pivotally mounted in the switch housing 1 on the shaft 1 B. The contact support 3 which is connected to the rocker arm 2 in operative connection and is slidably mounted in the switch housing 1 by means of contact support guide 1 A. Between the bottom wall 1 C of the switch housing 1 and the contact carrier 3 , a compression spring 6 is arranged, which serves as an energy store for the reset when switching off. The contact carrier 3 is equipped with the contact bridge 4 , the contact pressure of which is generated by the compression spring 7 , which is supported on the upper cross member 3 C of the contact carrier 3 .

Dem Kontaktträger 3 ist weiterhin an der oberen Traverse 3 C die Schulter 3 B angeformt sowie der Anschlag 3 A, der in Form zweier L-förmiger Klauen in der Ausschaltstellung des Kipphebels die zapfenförmigen Mitnehmer 2 B am Schaltnocken 2 A übergreift.The contact support 3 is further shoulder formed on the upper cross member 3 C 3 B and the stop 3 A, the two in the form of L-shaped jaw in the open position of the rocker arm, the pin-shaped driving element 2 B on switch cam engages 2 A.

Diese zapfenförmigen Mitnehmer sind gegenüber dem Rücken des Schaltnockens 2 A geringfügig zur Drehachse des Kipphebels 2 hin versetzt, damit diese nicht an der Schulter 3 B des Kontaktträ­ gers 3 anliegen und mechanische Kräfte im eingeschalteten Zu­ stand dauernd erfahren müssen.These pin-shaped blades are offset with respect to the back of the trip cam 2 A slightly toward the axis of rotation of the rocker arm 2 toward, so that they need to know not abut against the shoulder 3 of the B Kontaktträ gers 3 and mechanical forces in the switched to stand permanently.

Bedingt durch die Kraft der Druckfeder 6, wird die Schulter 3 B des Kontaktträgers 3 permanent gegen den Rücken des Schalt­ nockens 2 A gedrückt, so daß auch im Ausschaltzustand ein gerin­ ger Abstand zwischen dem zapfenförmigen Mitnehmer 2 B und dem An­ schlag 3 A gegeben ist, so daß im normalen Betrieb die zapfenför­ migen Mitnehmer 2 A keine Belastung erfahren, da die Umsetzung der Betätigungskräfte von der bogenförmigen Bewegung des Schalt­ nockens 2 A in die translatorische Bewegung des Kontaktträgers 3 nur zwischen dem Rücken des Schaltnockens 2 A und der Schulter 3 B des Kontaktträgers 3 erfolgt. Due to the force of the compression spring 6, the shoulder is pushed 3 B of the contact support 3 permanently against the back of the switching cam 2 A, so that even in the off state, a clotting ger distance between the peg-shaped driver 2 B and to blow 3 A, where , so that in normal operation the zapfenför shaped driver 2 A experience no load, since the implementation of the actuating forces from the arcuate movement of the switching cam 2 A in the translational movement of the contact carrier 3 only between the back of the switching cam 2 A and the shoulder 3 B of the contact carrier 3 takes place.

Wird der Schalter im Kurzschlußfalle oder beim Aufschalten auf einen Kurzschluß über das zulässige Schaltvermögen hinaus bean­ sprucht, besteht die Gefahr, daß die Kontakte 4 A/4 B an der Kon­ taktbrücke 4 mit den Gegenkontakten der Anschlüsse 5 A/5 B ver­ schweißen, so daß der Kraftschluß zwischen dem Schaltnocken 2 A und der Schulter 3 B des Kontaktträgers 3 aufgehoben wird.If the switch is used in the event of a short circuit or when switching to a short circuit beyond the permissible switching capacity, there is a risk that the contacts 4 A / 4 B on the contact bridge 4 weld with the counter contacts of the connections 5 A / 5 B , so that the frictional connection between the switching cam 2 A and the shoulder 3 B of the contact carrier 3 is canceled.

Der Kipphebel 2 ist nach dem Verschweißen dann nur geringfügig entsprechend dem Spiel zwischen Mitnehmer 2 B und Anschlag 3 Ab, auslenkbar, maximal bis zur Mittelstellung des Kipphebels hin, da zwischen den beiden klauenartig zusammenwirkenden Teilen eine formschlüssige Verbindung gegeben ist, die bei geringer Ver­ schweißung sogar ein mechanisches Aufbrechen der Kontakte bei entsprechender Krafteinwirkung auf den Kipphebel 2 ermöglicht.The rocker arm 2 is then only slightly after welding according to the game between the driver 2 B and stop 3 Ab , deflectable, up to the middle position of the rocker arm, since there is a positive connection between the two claw-like interacting parts, the weld with little Ver even a mechanical breaking of the contacts with the appropriate force on the rocker arm 2 allows.
