Description
Der Gegenstand der Erfindung ist ein Quecksilberschalter für Handlampen und andere ähnliche Apparate, die durch Drehen um 180 ° ein- bzw. ausgeschaltet werden können. Die Erfindung besteht darin, daß das Röhrchen für den Quecksilberschalter in seinem mittleren Teil nicht nur verengt, sondern in dieser Verengung noch in sich schraubenförmig verdreht ist.The subject of the invention is a mercury switch for hand lamps and others Similar devices that can be switched on or off by turning them 180 °. The invention is that the tube for the mercury switch in his middle part not only narrowed, but also helical in this narrowing is twisted.
• o Durch diese Verengung und Verdrehung wird gegenüber den bekannten Quecksilberschaltröhren, die nur eine einfache Verengung besitzen, der Vorteil erreicht, daß auch bei den stärksten Bewegungen und Erschütterungen des zu schaltenden Apparates ein unbeabsichtigtes Schalten ausgeschlossen ist, da die Schraubengänge der Verdrehung wie Scheidewände wirken. Weiter kann das Röhrchen eine verhältnismäßig große Festigkeit erhalten und sehr kurz gehalten werden.• o Through this narrowing and twisting becomes compared to the known mercury interrupter tubes, which only have a simple constriction, the advantage achieved that even with the strongest movements and vibrations of the device to be switched unintentional switching is impossible, since the Twist threads act like partitions. Furthermore, the tube can be given a relatively high strength and kept very brief.
Es ist dadurch möglich, den Quecksilberschalter auch in elektrische Apparate, z. B. Batterien, mit kleinsten Abmessungen einzubauen. This makes it possible to use the mercury switch in electrical equipment, e.g. B. Batteries with the smallest dimensions can be installed.
In der Zeichnung ist die Erfindung dargestellt, und zwar zeigenIn the drawing the invention is shown, namely show
Fig. ι den eigentlichen Quecksilberschalter, Fig. 2 eine Trockenbatterie mit' einem zwischen den Elementen angeordneten Quecksilberschaltröhrchen. Fig. Ι the actual mercury switch, Fig. 2 a dry battery with 'one between mercury interrupter tubes arranged in the elements.
Das vollständig geschlossene Kontaktröhrchen a, das aus Glas, Porzellan oder einem anderen geeigneten Werkstoff hergestellt ist, besitzt an dem einen Ende zwei Kontaktdrähte b und c, die, in an sich bekannter Weise gegeneinander isoliert, in das Kontaktröhrchen a dicht eingebracht sind.The completely closed contact tube a, which is made of glass, porcelain or some other suitable material, has two contact wires b and c at one end, which, insulated from one another in a manner known per se , are tightly inserted into the contact tube a.
Im Inneren des Kontaktröhrchens befindet sich eine geringe Menge Quecksilber d, das beim Drehen des Röhrchens um 180 ° in bekannter Weise entweder die metallische Verbindung zwischen den Kontaktdrähten b und c herstellt oder aufhebt.Inside the contact tube there is a small amount of mercury d which, when the tube is rotated 180 °, either establishes or removes the metallic connection between the contact wires b and c in a known manner.
Das Quecksilber wird zweckmäßig vor demEinfüllen in das Röhrchen wasserfrei gemacht, damit es eine gut zusammenhängende Masse bildet.The mercury is expediently anhydrous therewith before it is filled into the tube it forms a well-cohesive mass.
Das Kontaktröhrchen α ist in seinem mittleren Teile bei e verengt und in sich schraubenförmig verdreht.The contact tube α is narrowed in its middle part at e and twisted in a helical manner.
In Fig. 2 ist dargestellt, daß sich das Röhrchen infolge seiner äußerst gedrängten Form leicht in Batterien von geringen Abmessungen einbauen läßt.In Fig. 2 it is shown that the tube as a result of its extremely compact shape can be easily installed in batteries of small dimensions.
