Bei dem Einschraubstöpsel nach Patent 113 178 läfst sich die Sicherheit gegen Verwendung eines Stöpsels für höhere Stromstärke in einem Fassungstheil für geringere Stromstärke noch wesentlich erhöhen, wenn die Ausführung des Apparates in der in beiliegender Zeichnung veranschaulichten Weise erfolgt.With the screw-in plug according to patent 113 178 the security against the use of a plug for higher amperage can be achieved in one Substantially increase the socket part for lower amperage if the execution of the Apparatus takes place in the manner illustrated in the accompanying drawing.
Der Stromschlufsstempel f des Stöpsels ist so innerhalb des Stromschlufsringes angebracht, dafs nur ein verhältnifsmäfsig kurzes Stück des Stempels aus dem Hohlraum des Ringes hervortritt. Um die in dem Haupt - Patent beschriebene Wirkung zu erzielen, nämlich dafs ein Stromschlufs erst dann erfolgen kann, wenn der Stromschlufsstempel/zuvor in die Bohrung des Zwischenstückes b eingedrungen ist, mufs bekanntlich die Entfernung von Oberkante b bis Oberkante d geringer genommen werden als die Entfernung von Unterkante f bis Unterkante g. Es ist daher die Anordnung des Stromschlufsringes d in dem Fassungstheil a so gewählt, dafs der Abstand der beiderseitigen Oberkanten gleich Null ist.The power connection stamp f of the plug is attached inside the power connection ring in such a way that only a relatively short piece of the stamp protrudes from the cavity of the ring. In order to achieve the effect described in the main patent, namely that an electric circuit can only take place when the electric circuit punch / has previously penetrated the bore of the intermediate piece b , it is known that the distance from the top edge b to the top edge d must be taken less than that Distance from lower edge f to lower edge g. The arrangement of the current loop ring d in the socket part a is therefore chosen so that the distance between the top edges on both sides is equal to zero.
Der Zweck der Anordnung des Stempels innerhalb des Stromschlufsringes des Stöpsels liegt darin, dafs dadurch die Möglichkeit genommen wird, den Durchmesser des Stromschlufsstempels in böswilliger Absicht,. durch Abfeilen oder sonstige ähnliche Mittel zu verringern und so Stöpsel für zu hohe Stromstärken in die Fassungen einzuführen.The purpose of the location of the plunger within the electrical connection ring of the plug lies in the fact that the possibility is thereby taken away from the diameter of the electrical connection stamp maliciously. by filing or other similar means and thus inserting plugs for excessively high currents into the sockets.
