Description
Das Hauptpatent 549 859 betrifft eine Sicherheitssteckdose, bei der der eingebaute Schalter aus einem in einen Ringschlitz hineinragenden federnden Kontakt besteht, der beim Drehen des eingeführten Steckers mit dem den Gegenkontakt bildenden hohlzylindrischen Glied des Steckers zusammentritt, während das andere Kontaktpaar in an sich bekannter Weise von einem in der Drehachse der Steckvorrichtung liegenden, in eine Steckhülse einzuführenden Steckerstift gebildet wird.The main patent 549 859 relates to a safety socket in which the built-in Switch consists of a resilient contact protruding into an annular slot, the when turning the inserted plug with the hollow cylindrical one forming the mating contact Member of the plug comes together, while the other pair of contacts in a manner known per se of one in the axis of rotation the plug device lying, formed in a socket to be inserted plug pin will.
Diese Steckvorrichtung hat den Nachteil, daß die in der Drehachse liegende Steckhülse dauernd unter Spannung steht, und daß durch einen unglücklichen Zufall eine leitende Verbindung zwischen dieser Hülse und irgendwelchen Metallteilen entstehen kann, wodurch es zur Bildung von Funken kommt.This plug-in device has the disadvantage that the plug-in sleeve lying in the axis of rotation is constantly under tension, and that by an unfortunate coincidence a conductive connection between this sleeve and any metal parts, which can lead to the formation of sparks.
Die Verbesserung des Gegenstandes des Hauptpatents besteht daher nach der Erfindung darin, daß auch das zweite Kontaktpaar ebenso wie das erste durch einen Schalter ersetzt wird, und zwar in der Weise, daß zwei in den Ringschlitz hineinragende federnde Kontakte vorhanden sind, die beim Drehen des Steckers in der Dose mit je einem von zwei durch das hohlzylindrische Glied gebildeten Gegenkontakten verbünden werden.The improvement of the subject matter of the main patent therefore consists in accordance with the invention in that the second pair of contacts as well as the first are replaced by a switch is, in such a way that two projecting into the ring slot resilient contacts are present, which are formed when turning the plug in the socket with one of two by the hollow cylindrical member Counter contacts will be allied.
Zweckmäßig besteht dabei das hohlzylindrische Glied aus zwei gegeneinander isolierten, im Querschnitt die Gestalt eines Viertelringes aufweisenden Steckerstiften.The hollow cylindrical member expediently consists of two mutually insulated, in cross section the shape of a quarter ring having connector pins.
Damit der Strom nicht durch eine zufällige Verdreliung der beiden Kupplungshälften 3^ unterbrochen werden kann, sind in dem hohl- · zylindrischen Glied, d. h. in den Steckerstiften, Rasten vorgesehen, in die am Ende der Drehbewegung des Steckers die federnden Kontaktstifte einschnappen.So that the current cannot be interrupted by accidental twisting of the two coupling halves 3 ^, notches are provided in the hollow · cylindrical member, ie in the plug pins, into which the springy contact pins snap at the end of the rotary movement of the plug.
Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Steckvorrichtung dargestellt.In the drawing, an embodiment of the new connector is shown.
Abb. ι zeigt die eine Kupplungshälfte (Stecker) in Ansicht und die in ein Gehäuse 1 eingebaute zweite Kupplungshälfte (Steckdose) im Schnitt. Abb. 2 ist ein Schnitt durch den Stecker nach der Linie 2-2 der Abb. 1.Fig. Ι shows one coupling half (plug) in view and that in a housing 1 built-in second coupling half (socket) in section. Fig. 2 is a section through the plug according to line 2-2 in Fig. 1.
Die Steckdose besteht aus einem äußeren Isoliermantel 2, in dem ein Isolierstück 3 mittels einer Schraube 4 befestigt ist. "Zwischen Mantel 2 und Isolierstück 3 ist ein enger und tiefer Ringschlitz 5 gebildet, in den zwei die beiden Pole der Steckdose bildende federnde Stifte 6, 7 hineinragen. Vor diesen StiftenThe socket consists of an outer insulating jacket 2, in which an insulating piece 3 by means a screw 4 is attached. "Between the jacket 2 and the insulating piece 3 is a narrow and formed deep ring slot 5, in which two the two poles of the socket forming resilient Pins 6, 7 protrude. In front of these pens
