Mit Schlüssel schaltbarer und gegen unbefugtes öffnen gesicherter, elektrischer Gerätestecker und Schnurzwischenschalter. Key switchable and secured against unauthorized opening, electrical device plug and cord switch.

Die Neuerung betrifft eine elektrische Steckvorrichtung für Haushaltsgeräte und Maschinen im industriellen Anwendungsbereich. Derartige Geräte sollen aus Gründen der Sicherheit oder der kontrollierten Benützung häufig gegen unbefugte Inbetriebnahme geschützt werden.The innovation relates to an electrical connector for household appliances and machines in industrial applications. Such devices are said to be for security or controlled reasons Use must often be protected against unauthorized start-up.

Die in der Hauptanmeldung beschriebenen Gerätestecker und Schnurzwischenschalter sind mit einem Schalter ausgerüstet, welcher nur mit einem zugehörigen Schlüssel betätigt werden kann. Der Schlüssel kann in Schalterstellung EIN oder AUS abgezogen werden.The device plugs and cord switches described in the main application are equipped with a switch that can only be operated with an associated key. The key can be in the switch position ON or OFF can be withdrawn.

Dabei ist jedoch nicht verhindert, da3 Stecker oder Schnurzwischenschalter geöffnet werden können, um die Anschlußleitungen zu lösen oder Eingriffe am Schalterelement vorzunehmen.However, this does not prevent the plug or cord switch can be opened to loosen the connecting cables or interventions on the switch element.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherung gegen unbefugtes Demontieren einzubauen.The invention is based on the object of securing against unauthorized persons Dismantle to install.

Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß in der Schalterstellung AUS eine formschlüssige Sperre zwischen den beiden Teilen des Gerätesteckers, bzw. des Schnurzwischenschalters, hergestellt wird. In der Schalterstellung EIN wird diese Sperre wieder gelöst. Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt.This object has been achieved according to the invention in that in the switch position A positive lock is established between the two parts of the device plug or the cord switch. When the switch is in the ON position, this lock is released again. An embodiment of the innovation is shown in the drawing.

Fig. 1 zeigt einen Querschnitt durch einen mittels Schlüssel schaltbaren Gerätestecker.Fig. 1 shows a cross section through a switchable by means of a key Device plug.

Im Steckerdeckel 1 ist das Schloß 2 eingebaut, welches mit dem Schlüssel k betätigt wird. Über den Exzenterstift 3 wird die Schaltgabel 5 des Schnappmechanismus1 6 bewegt, wodurch über die Kontaktfeder 7 die Kontakte 8 geöffnet oder geschlossen werden.In the plug cover 1, the lock 2 is installed, which is operated with the key k . The shift fork 5 of the snap mechanism 1 6 is moved via the eccentric pin 3, whereby the contacts 8 are opened or closed via the contact spring 7.

Der Steckerdeckel 1 trägt die Sperre 12 welche mit dem Schnappmechanismus im geöffneten Zustand der Kontakte eine formschlüssige Verriegelung bildet.The plug cover 1 carries the lock 12 which with the snap mechanism forms a positive locking when the contacts are open.
