Description

Steckvorrichtung mit konzentrisch angeordneten Kontakten Bei Steckvorrichtungen sind die beim Ausschalten an den kontaktführenden Teilen auftretenden Trennungsfunken, besonders in Räumen mit leicht zündbaren Gasen, sehr gefährlich. Man ist daher stets bestrebt, die Steckvorrichtungen so auszubilden, daß der Trennungslichtbogen beim Ausschalten nur in einem abgeschlossenen Raum auftreten kann und sofort zum Erlöschen gebracht wird.Plug-in device with concentrically arranged contacts For plug-in devices are the separation sparks that occur on the contacting parts when switching off, especially in rooms with easily ignitable gases, very dangerous. One is therefore always strives to train the connectors so that the separating arc when Switching off can only occur in a locked room and immediately goes out is brought.

Die Erfindung bezieht sich auf eine Steckvorrichtung mit konzentrisch angeordneten Kontakten, bei der zur Erreichung einer hohen Abschaltleistung beim Abziehen des Steckers von der Steckdose ein Zusammenschlagen der Lichtbogen und damit ein Polfeuer mit großer Sicherheit vermieden wird. Erfindungsgemäß ragen die die Kontakte trennenden Isolierzwischenwände des Stekkers und der Steckdose so weit über ihre Kontakte hinaus, daß sie beim Öffnen der Steckerkontakte auch noch im Augenblick der Trennung der Kontakte eine vollkommen abgeschlossene Kammer bilden, in welcher der beim Abschalten entstehende Lichtbogen durch Überdruckwirkung zum Erlöschen gebracht wird. Ein Öffnen der durch die Isolierzwischenwände gebildeten Kammer erfolgt hierbei erst nach Unterbrechung des Lichtbogens zwischen den beiden äußeren Kontakten durch die als Funkenwischer wirkende Steckdosenkappe.The invention relates to a connector with concentric arranged contacts, in order to achieve a high breaking capacity in Unplugging the plug from the socket and striking the arc so that a pole fire is avoided with great certainty. According to the invention protrude the contacts separating insulating partitions of the plug and the socket so far beyond their contacts that they are also still in the when the plug contacts are opened Form a completely closed chamber at the moment of separation of the contacts, in which the arc created when switching off is caused by overpressure to the Is brought to extinction. An opening of those formed by the insulating partition walls Chamber takes place only after interruption of the arc between the two external contacts through the socket cap acting as a spark wiper.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar.The drawing shows an embodiment of the invention.

Die Steckdose enthält einen Steckerstift a und eine Kontakthülse b. Zwischen diesen beiden Teilen ist eine ringförmige isolierende Auskleidung c, deren Höhe derjenigen der Kappe d gleich ist, vorgesehen. Der Stecker enthält die konzentrisch angeordneten Kontakthülsen e, f und eine Isolierhülse g, die etwas über die Kontakthülsen ragt. Durch die isolierenden Zwischenwände c und g wird bei in die Steckdose eingeführtem Stecker eine abgeschlossene Kammer h gebildet, in der beim Herausziehen des Steckers aus der Dose durch den auftretenden Lichtbogen ein Überdruck entsteht, wobei der Lichtbogen erstickt bzw. klein gehalten und das Auftreten eines Polfeuers verhindert wird. Bei Öffnung der Kammer h befinden sich bereits die Kontakthülsen e, f des Steckers außerhalb der Steckdosenkappe d.The socket contains a plug pin a and a contact sleeve b. An annular insulating liner c, the height of which is the same as that of the cap d, is provided between these two parts. The plug contains the concentrically arranged contact sleeves e, f and an insulating sleeve g, which protrudes slightly over the contact sleeves. When the plug is inserted into the socket, the insulating partitions c and g form a closed chamber h in which, when the plug is pulled out of the socket, the arc that occurs creates an overpressure, the arc being suffocated or kept small and the occurrence of a pole fire is prevented. When the chamber h is opened, the contact sleeves e, f of the plug are already outside the socket cap d.

Da die Kappenöffnung j annähernd dem Durchmesser der äußeren Kontakthülse e des Steckers entspricht, tritt ein zwangläufiges Abwischen des Lichtbogens zwischen den beiden äußeren Kontakten e, b der Steckvorrichtung auf. Die Steckdosenkappe d wirkt somit als Funkenwischer.Since the cap opening j corresponds approximately to the diameter of the outer contact sleeve e of the plug, an inevitable wiping of the arc occurs between the two outer contacts e, b of the plug device. The socket cap d thus acts as a spark wiper.

Die Isolierauskleidung c der Dose wird so bemessen, daß eine Berührung spannungsführender Teile bei aus der Steckdose herausgezogenem Stecker verhindert wird.The insulating liner c of the can is dimensioned so that contact Live parts prevented when the plug is pulled out of the socket will.
