Description
Gegenstand der Erfindung ist eine Schaltkammer für Nockenschalter nach dem Anspruch 1, durch die ein gegenseitiger Austausch von Rast- und Schallstößeln bei flacher Bauweise ermöglicht istThe invention is a switching chamber for cam switches according to claim 1, through which a mutual exchange of latching and sonic plungers is made possible in the case of a flat design
Der Einsatz einer derartigen Schaltkammer hat auch den Vorteil, daß bei einfachen Schaltungen, für die Kontaktsysteme mit ungerader Anzahl benötigt werden, z. B. bei dreipoligen Ausschaltern, in die jeweils nicht durch ein Kontaktsystem belegte Seite das Rastsystem montiert wird.The use of such a switching chamber also has the advantage that with simple circuits for which Contact systems with an odd number are required, e.g. B. with three-pole circuit breakers, in each the side not occupied by a contact system the locking system is mounted.
Dadurch ergeben sich geringe Bautiefen. Zum anderen wird die Anzahl der verwendeten Teile geringer, da z. B. der Stößel für beide Systeme einsetzbar ist.This results in low installation depths. Second is the number of parts used lower, since z. B. the plunger can be used for both systems.
Eine vorteilhafte Ausgestaltung der Erfindung ist dem Anspruch 2 zu entnehmen.An advantageous embodiment of the invention can be found in claim 2.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt. Es zeigtEmbodiments of the invention are shown in the drawing. It shows
Fig. 1 eine offene Schaltkammer mit einem Schalt- und Rastsystem, einpolig,Fig. 1 shows an open switching chamber with a switching and latching system, single-pole,
F i g. 2 die schematische Darstellung eines Schalt- undF i g. 2 the schematic representation of a switching and
Rastsystems mit 60° Schaltwinkel,Locking system with 60 ° switching angle,
F i g. 3 die schematische Darstellung eines Schalt- und Rastsystems mit 30° Schaltwinkel.F i g. 3 the schematic representation of a switching and locking system with a switching angle of 30 °.
Die Schaltkammer 1 ist längs der Achse SA nach F i g. 1 symmetrisch aufgebaut. Beiderseitig dieser Achse befinden sich in der Gehäusewand der Schaltkammer 1 Schlitze 11 zur Aufnahme der Anschlußwinkel 2, die gleichzeitig als Festschaltstück ausgebildet sind. Die mittig gelagerte Nockenscheibe 7 betätigt mit ihren Rastkerben 71 und Schaltkerben 72 zwei Stößel, die einmal als Schaltstößel 3, zum anderen als Raststößel 3' eingesetzt sind. Schaltstößel 3 und Raststößel 3' sind identische Teile, die in den Fühmngsbahnen 12 geführt werden. In dem Schaltstößel 3 wird die Kontaktbrücke 4 gelagert. Beide Teile werden durch die Schaltstößelfeder 5 gegen die Nockenscheibe 7 gedrückt. Die gleiche Funktion übernimmt für den Raststößel 3' die Rastfeder 6.The switching chamber 1 is along the axis SA according to FIG. 1 constructed symmetrically. On both sides of this axis are located in the housing wall of the switching chamber 1 slots 11 for receiving the connection bracket 2, which are also designed as a fixed switching piece. The centrally mounted cam disk 7 actuates two tappets with its locking notches 71 and switching notches 72, which are used on the one hand as switching plungers 3 and on the other hand as latching plungers 3 '. Switching plunger 3 and latching plunger 3 'are identical parts that are guided in guide tracks 12. The contact bridge 4 is mounted in the switch plunger 3. Both parts are pressed against the cam disk 7 by the switch plunger spring 5. The detent spring 6 performs the same function for the detent plunger 3 '.
Es ist ohne weiteres möglich, statt des Rastsystems ein weiteres Kontaktsystem einzusetzen. Ein Rastsystem dient zur Fixierung der Schaltstellung für alle übrigen vor- und nachgeordneten Schaltkammern.It is easily possible to use a further contact system instead of the latching system. A locking system serves to fix the switching position for all other upstream and downstream switching chambers.
Das dargestellte Ausführungsbeispiel nach F i g. 1The illustrated embodiment according to FIG. 1
zeigt ein kombiniertes Schalt-Rast-System für einen Nockenschalter mit zwei Schaltstellungen, wie an der Anzahl der Rastkerben 71 der Nockenscheibe 7 zu erkennen ist.shows a combined switch-latch system for a cam switch with two switch positions, as in the Number of notches 71 of the cam disk 7 can be seen.
Die erforderlichen Einrichtungen zur Schaltwinkelbegrenzung wurden nicht dargestellt. Der Vollständigkeit halber sei darauf hingewiesen, daß die Kennkraftlinien der Schaltstößelfeder 5 und der Rastfeder 6 unterschiedlich sind. Fig.2 zeigt unter Weglassung der gemäß F i g. 1 erläuterten Teile eine Nockenscheibe für Nockenschalter mit drei Schaltstellungen, wie sie als Schaltung, z. B. für Umschalter, erforderlich sind.The devices required to limit the switching angle have not been shown. The completeness sake it should be pointed out that the characteristic lines of force of the switch plunger spring 5 and the detent spring 6 are different are. FIG. 2 shows, omitting the according to FIG. 1 explained parts of a cam disk for Cam switches with three switching positions, as they are used as a circuit, e.g. B. for changeover switches are required.
Während in Fi g. 1 und 2 kombinierte Schalt-Rast-Systeme für Geräte mit 60° Schaltwinkel dargestellt sind, zeigt Fig.3 ein solches System für Schalter mit 30° Schaltwinkel.While in Fi g. 1 and 2 combined switching / locking systems for devices with a switching angle of 60 ° are shown, Fig. 3 shows such a system for switches with 30 ° Switching angle.
Es liegt auf der Hand, daß sich außer den gezeigten Beispielen noch viele Varianten hinsichtlich des öffnungs- bzw. Schließvorganges der Kontaktseite finden lassen, wie sie ganz allgemein bei Programmschaltungen in vielfältigster Weise vorkommen können.It is obvious that, in addition to the examples shown, there are still many variants with regard to the opening or closing process of the contact side can be found, as is generally the case with program circuits can occur in a wide variety of ways.
