Description

Kupplungseinrichtung für Schnellschalter. Bei der Herstellung von Schnellschaltern ist es besonders wichtig, Kupplungsanordnungen auszuführen, bei denen zum Entkuppeln eine möglichst geringe Zeitspanne notwendig wird. Man muß deshalb dazu übergehen, von den sonst üblichen Klinkeinrichtungen, die zum Lösen eine gewisse Zeit brauchen, möglichst abzusehen. Eine ganz neue Lösung dieser Art wird in folgender Weise erreich, indem das Betätigungs- und das Stromschlußorgan je mit einer Anzahl Lamellen versehen sind, die fingerartig ineinandergreifen können. Beim Einschalten werden. diese Lamellen ineinandergelegt und durch irgendeine äußere Kraft gegeneinandergedrückt und so die Kupplung bewirkt. Tritt übeT-strom ein, so hat der Auslösernagnet nur nötig, die Kraft, die die Lamellen gegeneinanderpreßt, zu überwinden, und es wird dann durch die Einwirkung der beim Einschalten gespannten Federn die Abschaltung in verhältnismäßig sehr kurzer Zeit erfolgen. Diese ganze Anordnung ist als eine Art Reibungskupplung aufzufassen, bei der zum Zusammenpressen selbst nur eine sehr geringe Kraft notwendig wird, die leicht durch den überstrommagneten überwunden werden kann,. während nach Überwindung dieser Kraft das Lösen sehr rasch vor sich geht. Es ist noch wirkungsvoller und es ist weniger Kraftbedarf zum Zusammenhalten notwendig, wenn die einzelnen Lamellen selbst keilförmige Gestalt erhalten. Die Abbildung zeigt die Anordnung in gekuppeltem Zustand. a und b sind die beiden zu kuppelnden Glieder, die durch angreifende Kräfte in C und il zusammengedrückt werden. Die Pfeile deuten die zum Zusammenhalten notwendige Kraftwirkung an. Wie diese Kraft zur Wirkung kommt bzw. durch den Auslösemagneten aufgehoben wird, ist für den Erfindungsgedanken ohne Bedeutung.Coupling device for quick switch. In the manufacture of high-speed switches, it is particularly important to implement coupling arrangements in which the shortest possible time is necessary for decoupling. One must therefore go over to the otherwise usual latching devices, which need a certain time to loosen, as far as possible. A completely new solution of this type is achieved in the following way, in that the actuating and the current-closing element are each provided with a number of lamellae which can interlock like fingers. When switched on will be. these lamellae are placed one inside the other and pressed against each other by some external force, thus causing the coupling. If overflow current occurs, the release magnet only needs to overcome the force that presses the lamellas against each other, and the shutdown will then take place in a relatively very short time due to the action of the springs tensioned when switching on. This entire arrangement is to be understood as a kind of friction clutch, in which only a very small force is required for the compression itself, which can easily be overcome by the overcurrent magnet. while after overcoming this force the loosening goes on very quickly. It is even more effective and less force is required to hold it together if the individual slats themselves have a wedge-shaped shape. The illustration shows the arrangement in the coupled state. a and b are the two links to be coupled, which are pressed together by acting forces in C and il. The arrows indicate the force required to hold them together. How this force comes into effect or is canceled by the release magnet is irrelevant to the concept of the invention.

PATENTANSPRTJCHF: i. Kupplungseinrichtung für Schnellschalter, dadurch gekennzeichnet, daß an denn Betätigungsorgan und den Schaltteilen Lamellen angebracht sind, die in der Einschaltstellung gabelförmig ineinandergreifen und als eine Art Reibungskupplung durch eine geringe äußere Kraft zusammengepreßt eine sichere Verbindung bilden, während zwecks Ausschaltung durch den Auslösemagneten die das Zusam'rnenpressen bewirkende Kraft überwunden und dadurch ein schnelles Lösen der Reibungskupplung bewirkt wird. z. Einrichtung nach Anspruch i,, dadurch ;gekennzeichnet, daß die Lamellen keilförmig ausgebildet sind. PATENT APPLICATION: i. Coupling device for high-speed switches, characterized in that lamellae are attached to the actuating member and the switching parts, which interlock in the form of a fork in the switched-on position and, when pressed together by a small external force, form a secure connection as a kind of friction clutch, while the release magnet makes the connection for the purpose of disconnection. Rnenpressen causing force is overcome and thereby a quick release of the friction clutch is effected. z. Device according to claim 1, characterized in that the lamellae are wedge-shaped.
