Abstract

A protective cap is provided to safeguard the plug contact against dangerous touch. On insulation into a plug socket, the cap is automatically delatched and retracted. On the other hand, on retracting from the socket, the cap moves automatically forward into the protective position and is latched there. Preferably the cap is fitted with locking fingers, which are pressed outwards for better latching by a soring. The latching mechanism may be fitted with several such locking fingers, in order to prevent delatching by hand, without plugging-in into a socket. Thus the mechanism provides enhanced protection against dangerous touch.

Description

Stecker mit verriegeltem BerührungsschutzPlug with locked contact protection

In Labors werden oft Verbindungsleitungen benutzt, die an beiden den Dananenstecker haben.In laboratories, connecting lines are often used that connect to both the Have Dananen plug.

Bei Versuchen mit 220 V/380 V besteht hesonders für Schüler Lebensgefahr.Experiments with 220 V / 380 V are particularly dangerous for pupils.

Zum Schutz gegen zu hohe i3erilhrungsspannung von nicht eingesteckten zweiten Enden einer Verbindungsleitung kennt man zwei schutzarten.To protect against excessive contact voltage from unplugged There are two types of protection at the second ends of a connecting line.

Einmal hat man einen Stecker mit Schutzrohr, der eine aufwendige Steckbuchse benötigt.Once you have a plug with a protective tube, which has a complex socket needed.

Eine andere bekannte Art des Schutzes ist ein Kunststoffrohr.Another known type of protection is a plastic pipe.

um den Stecker, daß sich heim Einstecken des Steckers zurückschiebt. Für diesen Stecker kann man eine normale Buchse verwenden.around the plug that pushes back when the plug is inserted. A normal socket can be used for this plug.

Es besteht aber die gefahr, daß man die leicht zurückschiebbare Schutzhülle zurück drückt und Kontakt mit den Spannung fiihrenden Teilen hekommt.But there is a risk that the protective cover, which can be easily pushed back, will be lost pushes back and comes into contact with the live parts.

Die Erfindung, die dieser Anmeldunq zugrunde liegt, hat die vorhin beschriebenen Nachteile nicht.The invention on which this application is based has the previous one disadvantages described not.

Bild 1 zeigt den Stecker mit verriegeltem Beriihrungsschutz.Fig. 1 shows the plug with the touch guard locked.

Die Verriegelung, Teil 1, verhindert, daß das Schutzrohr (Teil 2) zurückgeschoben wird.The interlock, part 1, prevents the protective tube (part 2) is pushed back.

Erst beim Einstecken in eine Buchse werden die einzelnen Sperrfinger zurückgedrückt und antriegeln das Schutzrohr.The individual locking fingers are only activated when they are inserted into a socket pushed back and unlocked the protective tube.

Danach kann der Stecker komplett eingesteckt werden.The plug can then be fully inserted.

Beim Herausziehen des Steckers schiebt sich zuerst wegen der Feder (Teil 6) die Schutzhülle über'den Kontakt und die Sperrfinger. Erst danach spreizen sich durch das Weiterhinausziehen die Sperrfinger und verriegeln die Schutzhfllle, Ein Berühren Spannung führender Teile ist nicht mehr möglich.When pulling out the plug, it pushes itself first because of the spring (Part 6) the protective cover over the contact and the locking fingers. Only then spread it by continuing to pull out the locking fingers and lock the protective cover, It is no longer possible to touch live parts.
