Abstract

Disclosed is a coupling device that is located on the actuating member of a switching device (1) such as one as used in a power circuit breaker. The coupling device has a through hole (33) on the actuating member. A coupling element (40) can be inserted into said through hole. When the coupling element (40) is assembled, a first end section (47) thereof protrudes from one end (35) of the through hole (33). A second end section (47) thereof is flush with the opposite end (34) of the through hole (33). In this position, the coupling element (40) forms a recess (25) on one end of the actuating member and the end section (47) of the coupling element (40) protrudes on the other end. Said protruding end section (47) is embodied in such a way that it fits into the recess (25).

Description

Die Erfindung bezieht sich auf eine Kopplungseinrichtung eines Betätigungselements einer Schalteinrichtung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a coupling device of an actuating element of a switching device according to the preamble of claim 1.

Eine derartige Kopplungseinrichtung ist, wie z.b. aus dem GB 2 285 890 A bekannt, an dem Betätigungselement eines einpoligen Leitungs-, Fehlerstrom- oder Motorschutzschalters vorgesehen. An diese Schalter werden oftmals Schalteinrichtungen wie Zubehörschalter, Fernauslöser oder Hilfsschalter angebaut bzw. angestapelt. Zur synchronen Betätigung der Schalter sind die Betätigungselemente derart gestapelter Schalter mit Hilfe eines Kopplungsteiles verbindbar.Such a coupling device is, as z.b. from GB 2 285 890 A, provided on the actuating element of a single-pole line, residual current or motor protection switch. Switching devices such as accessory switches, remote triggers or auxiliary switches are often attached or stacked to these switches. For synchronous actuation of the switches, the actuators of such a stacked switch by means of a coupling member are connectable.

Aus dem Stand der Technik ist bekannt, ein solches Kopplungsteil als eine Rundachse auszubilden, die durch Durchgangslöcher von Betätigungselementen benachbarter Schalter verschiebbar ist. Beispielsweise kann ein Hilfsschalter an einen LS-Schalter angebaut werden, wobei eine solche Rundachse durch die Durchgangslöcher der Betätigungselemente beider Schalter geschoben wird. Da die Rundachse innerhalb der Durchgangslöcher der Betätigungselemente eingeschoben ist, kann die Rundachse nicht dafür verwendet werden, weitere Zusatzeinrichtungen an den bereits angebauten Hilfsschalter anzubauen.From the prior art it is known to form such a coupling part as a rotary axis, which is displaceable through through holes of actuators of adjacent switches. For example, an auxiliary switch can be attached to an LS switch, wherein such a rotary axis is pushed through the through holes of the actuating elements of both switches. Since the rotary axis is inserted within the through holes of the actuators, the rotary axis can not be used to attach additional options to the already attached auxiliary switch.

Aus dem Stand der Technik ist auch bekannt, an das Betätigungselement eines Hilfsschalters einen als ein Kopplungsteil dienenden Vorsprung anzuformen. Wenn der Hilfsschalter beispielsweise an einen LS-Schalter angebaut wird, ist dieser Vorsprung in eine geeignete Vertiefung im Betätigungselement des LS-Schalters versenkbar, wodurch die beiden Schalter miteinander gekoppelt sind. Solche mit einem Vorsprung versehene Betätigungselemente von Hilfsschaltern sind allerdings konstruktionsbedingt nur an entweder der linken oder der rechten Seite des Betätigungselements eines LS-Schalters anbaubar.It is also known from the prior art to form a projection acting as a coupling part on the actuating element of an auxiliary switch. For example, if the auxiliary switch is attached to a circuit breaker, this projection will be in a suitable recess in FIG Actuator of the LS switch retractable, whereby the two switches are coupled together. Such provided with a projection actuators of auxiliary switches, however, are structurally only on either the left or the right side of the actuator of a circuit breaker attachable.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Kopplungseinrichtung eines Betätigungselements eines Schalters zu schaffen, mit deren Hilfe an beiden Seiten des Betätigungselements eine einfache und schnelle Kopplung von Betätigungselementen weiterer Schalteinrichtungen möglich ist. Auch soll die Kopplungseinrichtung eine Stapelung einer Mehrzahl von Schalteinrichtungen erlauben.The invention is therefore an object of the invention to provide a coupling device of an actuating element of a switch, with the help of both sides of the actuating element, a simple and fast coupling of actuators of other switching devices is possible. Also, the coupling device should allow stacking of a plurality of switching devices.

In Fig. 1 ist eine schematische Seitenansicht eines einpoligen Schalters 1 gezeigt. Der Schalter 1 weist einen Knebel 10 auf, der normalerweise aus Kunststoff, z.B. einem Thermoplast, besteht. Dieser Knebel ist im Schalter 1 gelagert und um eine Schwenkachse 11 in eine Ein- und Ausschaltstellung schwenkbar. Der Knebel 10 hat ein Betätigungselement 20, das über eine in Fig. 2a angedeutete Steckverbindung 2 an den Knebel 10 angebracht ist. Weiterhin ist in dem Betätigungselement 20 ein parallel zur Schwenkachse 11 verlaufendes Durchgangsloch 33 ausgebildet.In Fig. 1 is a schematic side view of a single-pole switch 1 is shown. The switch 1 has a knob 10 which is normally made of plastic, e.g. a thermoplastic. This knob is mounted in the switch 1 and pivotable about a pivot axis 11 in an on and off position. The knob 10 has an actuating element 20 which is attached via a in Fig. 2a indicated plug-in connection 2 to the knob 10. Furthermore, a parallel to the pivot axis 11 extending through hole 33 is formed in the actuating element 20.

Gegenüberliegend zum Knebel 10 weist der in Fig. 1 gezeigte Schalter 1 einen Montageabschnitt 12 auf, mit desser. Hilfe der Schalter 1 an eine nicht gezeigte Halteschiene anbringbar ist.Opposite the knob 10, the switch 1 shown in Fig. 1 on a mounting portion 12, with desser. Help the switch 1 can be attached to a holding rail, not shown.

Fig. 2a zeigt eine Schnittansicht des oben erwähnten Betätigungselements 20. Zur Ausbildung der Kopplungseinrichtung ist in dem Durchgangsloch 33 des Betätigungselements ein später beschriebenes Kopplungsteil 40 eingeschoben.Fig. 2a shows a sectional view of the above-mentioned actuating element 20. To form the coupling device, a later-described coupling part 40 is inserted in the through hole 33 of the actuating element.

Das Durchgangsloch 33 eines solchen Betätigungselements 20 ist - wie in Fig. 4 gezeigt - rechtwinklig mit Innenwänden 21 bis 24 ausgebildet. Weiterhin ist das Durchgangsloch 33 generell in einen Einführbereich 36 und einen Klemmbereich 37 aufgeteilt, wie in Fig. 3ä veranschaulicht ist.The through hole 33 of such an actuating element 20 is - as shown in Fig. 4 - formed at right angles with inner walls 21 to 24. Furthermore, the through-hole 33 is generally divided into an insertion portion 36 and a clamping portion 37, as illustrated in FIG. 3 a.

Mit Hilfe des Einführbereiches 36 wird ein Einführen des Kopplungsteils 40 ausgehend von einem in Fig. 3a linken Einführende 34 in das Durchgangsloch 33 erleichtert. Hierzu ist im Einführbereich 36 der Abstand der oberen und unteren Innenwände 21 und 22 zum Einführende 34 hin vergrößert.With the aid of the insertion region 36, insertion of the coupling part 40 is facilitated starting from a left insertion end 34 in FIG. 3a into the through hole 33. For this purpose, in the insertion region 36, the distance of the upper and lower inner walls 21 and 22 to the insertion end 34 is increased.

An den Einführbereich 36 schließt sich der Klemmbereich 37 an, der das Kopplungsteil 40 gegen ein Herausfallen aus dem Durchgangsloch sichert. Dem Klemmbereich 37 ist ein gemäß Fig. 3a rechtes Austrittsende 35 des Durchgangsloches 33 zugeordnet.Adjoining the insertion region 36 is the clamping region 37, which secures the coupling part 40 from falling out of the through hole. The clamping region 37 is associated with a right outlet end 35 of the through hole 33 according to FIG. 3a.

Im Klemmbereich 37 ist an der gemäß Fig. 3a oberen Innenwand 21 des Durchgangsloches 33 eine Rastnase 26 vorgesehen, die zur später beschriebenen Verrastung mit dem Kopplungsteil 40 dient. Der Rastnase 26 gegenüberliegend ist eine Schulter 27 angeordnet, die gemäß Fig. 3a vom Austrittsende 35 versetzt im Inneren des Durchgangsloches 33 und an der unteren Innenwand 22 des Durchgangsloches 33 ausgebildet ist. Die Schulter 27 weist eine Begrenzungsfläche 28 und eine Anlagefläche 29 auf. Hierbei ist die Begrenzungsfläche 28 dem Einführende 34 des Durchgangsloches 33 zugewandt.In the clamping region 37, a latching nose 26 is provided on the upper wall 21 of the through hole 33 according to FIG. 3a, which serves for the latching with the coupling part 40 described later. The latching lug 26 opposite a shoulder 27 is arranged, the offset according to FIG. 3a from the outlet end 35 in the interior of the through hole 33 and on the lower inner wall 22 of the through hole 33 is formed. The shoulder 27 has a boundary surface 28 and a contact surface 29. Here, the boundary surface 28 facing the insertion end 34 of the through hole 33.

Das Kopplungsteil 40 ist in Fig. 3b ausführlich dargestellt. Demgemäß weist das Kopplungsteil 40 einen im wesentlichen rechteckigen Basisabschnitt 51 auf, der in Fig. 3b durch gestrichelte Linien eingegrenzt ist. Dem Basisabschnitt 51 schließen sich ein in Fig. 3b rechts befindlicher vorderer Endabschnitt 47 und ein links befindlicher hinterer Endabschnitt 50 an. Sowohl am vorderen Endabschnitt 47 als auch am hinteren Endabschnitt 50 sind Vorsprünge 41, 42 und Rücksprünge 43, 44 vorgesehen.The coupling part 40 is shown in detail in FIG. 3b. Accordingly, the coupling member 40 has a substantially rectangular base portion 51, which is bounded in Fig. 3b by dashed lines. The base section 51 is followed by a front end section 47 located on the right in FIG. 3b and a rear section located on the left End section 50 at. Both at the front end portion 47 and at the rear end portion 50 projections 41, 42 and recesses 43, 44 are provided.

Genauer gesagt zeigen der am hinteren Endabschnitt 50 angeordnete Vorsprung 41 und der am vorderen Endabschnitt 47 angeordnete Vorsprung 42 entlang einer Symmetrieachse X des Basisabschnitts 51 in entgegengesetzte Richtungen. Zudem sind die Vorsprünge 41 und 42 - in zur Symmentrieachse X senkrechter Richtung - zueinander versetzt angeordnet. D.h., daß dem am hinteren Endabschnitt 50 befindlichen Vorsprung 41 der am vorderen Endabschnitt 47 befindliche Rücksprung 44 gegenüberliegt. Entsprechend liegt dem am hinteren Endabschnitt 50 befindlichen Rücksprung 43 der am vorderen Endabschnitt 47 befindliche Vorsprung 42 gegenüber.More specifically, the protrusion 41 disposed on the rear end portion 50 and the protrusion 42 on the front end portion 47 along an axis of symmetry X of the base portion 51 face in opposite directions. In addition, the projections 41 and 42 - arranged offset to each other in the direction perpendicular to the axis of symmetry X -. That is, the protrusion 41 located at the rear end portion 50 faces the recess 44 located at the front end portion 47. Accordingly, located at the rear end portion 50 recess 43 of the front end portion 47 located on the projection 42 is opposite.

Dem Rücksprung 44 des vorderen Endabschnittes 47 schließt sich gemäß Fig. 3b eine Abstufung 45 an, die an der unteren Längsseite 49 des Kopplungsteils 40 angeordnet ist. Der Abstufung 45 gegenüberliegend sind an der oberen Längsseite 48 zwei Vertiefungen 46a, 46b vorgesehen, die in Richtung der Symmetrieachse X voneinander beabstandet sind.The recess 44 of the front end portion 47 is followed, according to FIG. 3b, by a step 45, which is arranged on the lower longitudinal side 49 of the coupling part 40. The gradation 45 opposite 48 two recesses 46 a, 46 b are provided on the upper longitudinal side, which are spaced apart in the direction of the axis of symmetry X.

Das Einführen des Kopplungsteils 40 in das Durchgangsloch 33 des Betätigungselements 20 ist in der Raumansicht aus Fig. 4 dargestellt. Demnach wird zunächst der vordere Endabschnitt 47 des Kopplungsteils 40 in Pfeilrichtung A durch das Eintrittsende 34 in den Einführbereich 36 des Durchgangsloches 33 eingeschoben. Hierbei kann sich der vordere Endabschnitt 47 des Kopplungsteils 40 solange frei durch den Einführbereich 36 des Durchgangsloches 33 bewegen, bis der vordere Endabschnitt 47 an der Rastnase 26 oder der Schulter 27 des Klemmbereichs 37 anstößt.The insertion of the coupling part 40 into the through hole 33 of the actuating element 20 is shown in the room view of FIG. 4. Accordingly, first the front end portion 47 of the coupling part 40 is inserted in the direction of arrow A through the entry end 34 into the insertion region 36 of the through hole 33. Here, the front end portion 47 of the coupling member 40 as long as free to move through the insertion portion 36 of the through hole 33 until the front end portion 47 abuts the locking lug 26 or the shoulder 27 of the clamping portion 37.

Damit das Kopplungsteil 40 den von der Rastnase 26 entgegengebrachten Widerstand überwinden und den Klemmbereich 37 durchdringen kann, muß die auf den hinteren Endabschnitt 50 des Kopplungsteils ausgeübte Schubkraft merklich erhöht werden. Bei ausreichender Schubkraft kann dann der vordere Endabschnitt 47 des Kopplungsteils 40 in den Klemmbereich 37 vordringen und in die in Fig. 2a gezeigte erste Montageposition gebracht werden.So that the coupling part 40 overcome the resistance provided by the latching lug 26 and the clamping area 37, the thrust force exerted on the rear end portion 50 of the coupling part must be remarkably increased. With sufficient thrust force, the front end portion 47 of the coupling part 40 can then penetrate into the clamping region 37 and be brought into the first mounting position shown in Fig. 2a.

In dieser ersten Montageposition ist der Vorsprung 41 des Kopplungsteils 40 in dem Durchgangsloch 33 derart eingesenkt, daß er am Eintrittsende 34 des Durchgangsloches 33 ansteht. Ferner ergibt der Rücksprung 43 des Kopplungsteiles zusammen mit den Innenwänden 21, 23 und 24 des Durchgangsloches 33 eine Ausnehmung 25. Im Gegensatz zum eingesenkten Vorsprung 41 ragt der gegenüberliegende Vorsprung 42 aus dem Austrittsende 35 des Durchgangsloches 33 heraus.In this first mounting position, the projection 41 of the coupling part 40 is sunk in the through hole 33 so as to be present at the entry end 34 of the through hole 33. Further, the recess 43 of the coupling part together with the inner walls 21, 23 and 24 of the through hole 33 results in a recess 25. In contrast to the recessed projection 41, the opposite projection 42 projects out of the outlet end 35 of the through hole 33.

Zur Festlegung der in Fig. 2a gezeigten ersten Montageposition ist die im Durchgangsloch 33 vorhandene Rastnase 26 in eine 46a der Vertiefungen 46a, 46b eingerastet. Zusätzlich kann sich in der ersten Montageposition - wie in Fig. 2a gezeigt - die Abstufung 45 des Kopplungsteils 40 mit der Begrenzungsfläche 28 der Schulter 27 in Anlage befinden.To fix the first mounting position shown in Fig. 2a, the present in the through hole 33 latch 26 is engaged in a 46a of the recesses 46a, 46b. In addition, in the first mounting position - as shown in Fig. 2a - the gradation 45 of the coupling member 40 with the boundary surface 28 of the shoulder 27 are in abutment.

Ausgehend von der ersten Montageposition gemäß Fig. 2a ist das Kopplungsteil 40 in eine zweite Montageposition verschiebbar. Hierzu muß lediglich auf den Vorsprung 42 des Kopplungsteils 40 entgegen der in Pfeilrichtung A zeigenden Einführrichtung eine Druckkraft ausgeübt werden. Dadurch kann sich zunächst die Verrastung zwischen der Rastnase 26 und der Vertiefung 46a lösen, woraufhin das Kopplungsteil 40 verschoben werden kann bis die Rastnase 26 in die weitere Vertiefung 46b einrastet. Durch diese Verrastung wird - entsprechend der ersten Montageposition - die zweite Montageposition festgelegt. Die dabei vom Kopplungsteil 40 zurückgelegte Verschiebestrecke zwischen der ersten und zweiten Montageposition entspricht dem Abstand der Vertiefungen 46a, 46b.Starting from the first mounting position according to FIG. 2a, the coupling part 40 is displaceable in a second mounting position. For this purpose, only on the projection 42 of the coupling part 40 against the pointing in the direction of arrow A insertion a pressure force must be exercised. As a result, the latching between the latching lug 26 and the recess 46a can first be released, whereupon the coupling part 40 can be displaced until the latching lug 26 engages in the further recess 46b. By this locking the second mounting position is determined - according to the first mounting position. The thereby covered by the coupling member 40 displacement distance between the first and second mounting position corresponds to the distance of the recesses 46a, 46b.

In der zweiten Montageposition ist - wie oben erwähnt - der Vorsprung 42 des Kopplungsteils 40 in dem Durchgangsloch 33 derart eingesenkt, daß er am Austrittsende 35 des Durchgangsloches 33 ansteht. Ferner ergibt der Rücksprung 44 des Kopplungsteiles zusammen mit den Innenwänden 22, 23 und 24 des Durchgangsloches eine Ausnehmung. Demgegenüber ragt der Vorsprung 41 aus dem Eintrittsende 34 des Durchgangsloches 33 heraus.In the second mounting position is - as mentioned above - the projection 42 of the coupling part 40 in the through hole 33 is sunk in such a way that it is present at the outlet end 35 of the through hole 33. Further, the recess 44 of the coupling member together with the inner walls 22, 23 and 24 of the through hole results in a recess. On the other hand, the protrusion 41 protrudes from the entrance end 34 of the through hole 33.

Wie weiter aus der Fig. 2a ersichtlich, ist die Abstufung 45 der Kontur der Schulter 27 angepaßt. Daraus ergibt sich, daß das Kopplungsteil 40 nur seitenrichtig in das Durchgangsloch 33 eingeschoben werden kann.As further seen in FIG. 2a, the gradation 45 of the contour of the shoulder 27 is adapted. It follows that the coupling member 40 can only be inserted into the through hole 33 laterally correct.

Wird das Kopplungsteil 40 dagegen nicht seitenrichtig in das Durchgangsloch 33 eingeschoben, verkantet das Kopplungsteil 40 im Klemmbereich 37 des Durchgangsloches. Es ist daher nicht möglich, das falsch eingeschobene Kopplungsteil sachgemäß im Durchgangsloch 33 einzuklemmen.On the other hand, if the coupling part 40 is not pushed into the through-hole 33 in the correct direction, the coupling part 40 jams in the clamping region 37 of the through-hole. It is therefore not possible to pinch the wrongly inserted coupling part properly in the through hole 33.

Nachstehend wird der Fall betrachtet, wonach an einem an der nicht gezeigten Halteschiene montierten LS-Schalter zusätzliche Hilfsschalter oder Zubehörschalter zur synchronen Betätigung angebaut werden.The case will be considered below, according to which additional auxiliary switches or accessory switches for synchronous operation are mounted on a circuit breaker mounted on the holding rail, not shown.

Hierzu sind Fig. 2b die Betätigungselemente aneinander gestapelter Schalter gezeigt. Genauer gesagt ist in Fig. 2b dargestellt, daß an der linken Seite eines (in Fig. 2b rechten) LS-Schalters weitere Zubehörschalter oder Hilfsschalter angestapelt sind.For this purpose, Fig. 2b, the actuators are shown stacked switch. More precisely, it is shown in FIG. 2b that further accessory switches or auxiliary switches are stacked on the left side of an LS switch (on the right in FIG. 2b).

Für diesen Zweck ist in jedem Betätigungselement 20 der anzubauenden Zubehörschalter zunächst das Kopplungsteil 40 in die in Fig. 2a gezeigte erste Montageposition gebracht worden, wogegen das (in Fig. 2b rechte) Betätigungselement des LS-Schalters mit keinem derartigen Kopplungsteil 40 versehen werden muß.For this purpose, in each actuator 20 of the accessory switch to be mounted first the coupling member 40 in the first mounting position shown in Fig. 2a has been brought, whereas the (in Fig. 2b right) actuator of the LS-switch with no such coupling member 40 must be provided.

Anschließend werden die Zubehörschalter über ihre Montageabschnitte 12 nacheinander an die linke Seite des Betätigungselements 20 des LS-Schalters angestapelt, wodurch der Vorsprung 42 des Betätigungselements des ersten Zubehörschalters in das Durchgangsloch 33 des Betätigungselements des LS-Schalters versenkt wird. Der Vorsprung 42 des Betätigungselements des zweiten Zubehörschalters (in Fig. 2b der linke Schalter) wird formschlüssig in die Ausnehmung 25 des ersten Zubehörschalters eingesetzt.Subsequently, the accessory switches are sequentially stacked via their mounting portions 12 to the left side of the actuator 20 of the circuit breaker, whereby the projection 42 of the actuator of the first accessory switch is sunk into the through hole 33 of the actuator of the circuit breaker. The projection 42 of the actuating element of the second accessory switch (in Fig. 2b, the left switch) is positively inserted into the recess 25 of the first accessory switch.

Erfindungsgemäß können die Betätigungselemente solcher Zubehörschalter in einfacher Weise derart abgewandelt werden, daß diese nicht nur - wie anhand der Fig. 2b gezeigt ist - an die linke Seite des LS-Schalters, sondern auch an die rechte Seite des LS-Schalters stapelbar sind.According to the invention, the actuators of such accessory switches can be modified in a simple manner that they not only - as shown with reference to FIG. 2b - are stackable to the left side of the LS-switch, but also to the right side of the LS-switch.

Gemäß dem Fig. 2b können also die Betätigungselemente 20 von Hilfsschaltern lediglich durch ein Verschieben ihrer Kopplungsteile 40 angepaßt werden, um beidseitig - d.h. an der rechten oder an der linken Seite - an den LS-Schalter stapelbar zu sein. Eine solche installationsfreundliche Stapelung ist aber auch zwischen den Betätigungselementen der Zubehörschalter möglich.According to FIG. 2b, therefore, the actuators 20 of auxiliary switches can only be adapted by displacing their coupling parts 40 in order to prevent them on both sides - i. on the right or left side - to be stackable on the LS switch. But such an installation-friendly stacking is also possible between the actuators of the accessory switch.

Ferner ist es hierdurch selbstverständlich möglich, an beiden Seiten eines LS-Schalters Hilfsgeräte anzubauen und deren Betätigungselemente mit dem Betätigungselement des LS-Schalters zu verbinden.Furthermore, it is therefore possible, of course, to cultivate auxiliary devices on both sides of a circuit breaker and to connect their actuating elements to the actuating element of the circuit breaker.

Ein weiteres Ausführungsbeispiel der Erfindung ist in den Fig. 5a und 5b gezeigt.Another embodiment of the invention is shown in Figs. 5a and 5b.

Die Fig. 5a zeigt einen LS-Schalter mit einem Knebel 10, einem Betätigungselement 20 und einem Auslösehebel 60. Der Auslösehebel 60 ist um eine Drehachse 62 schwenkbar und weist ein Loch 61 auf. Das Loch 61 kann als Durchgangsloch ausgebildet sein und dieselbe Gestalt wie das Durchgangsloch 33 nach Fig. 3a haben, oder es können auf beiden Seiten des Auslösehebels Sacklöcher vorgesehen sein, die dieselbe Gestalt wie die Endabschnitte des Durchgangsloches 33 aufweisen. Alternativ hierzu kann ein solches Sackloch jedwede Gestalt haben, die dazu geeignet ist, den ersten oder zweiten Endabschnitt 47, 50 aufzunehmen.FIG. 5 a shows an LS switch with a toggle 10, an actuating element 20 and a triggering lever 60. The triggering lever 60 is pivotable about an axis of rotation 62 and has a hole 61. The hole 61 can as a through hole be formed and have the same shape as the through hole 33 of FIG. 3a, or it may be provided on both sides of the trigger lever blind holes having the same shape as the end portions of the through hole 33. Alternatively, such a blind hole may have any shape suitable for receiving the first or second end portions 47, 50.

Ein mit dem Auslösehebel 60 vergleichbarer Hebel ist auch in der anzubauenden Schalteinrichtung vorgesehen. Die Fig. 5b zeigt einen Abschnitt 70 dieses Hebels, der ein Durchgangsloch 33 aufweist, das die Gestalt des Durchgangsloches 33 nach Fig. 3a hat. In dieses Durchgangsloch läßt sich in der gleichen Weise ein Kopplungsteil 40 einsetzen, wie es oben im Zusammenhang mit dem ersten Ausführungsbeispiel erläutert wurde.A similar to the trigger lever 60 lever is also provided in the switching device to be mounted. Fig. 5b shows a portion 70 of this lever, which has a through hole 33 which has the shape of the through hole 33 of Fig. 3a. In this through hole, a coupling member 40 can be used in the same manner, as explained above in connection with the first embodiment.

Darüber hinaus sind in der linken und rechten Gehäusewand des LS-Schalters und der anzubauenden Schalteinrichtung (nicht gezeigte) Öffnungen vorgesehen, die die Löcher 61 bzw. 33 über ihre gesamte Bewegungsbahn freilegen.In addition, openings (not shown) are provided in the left and right housing walls of the circuit breaker and the switching device to be mounted, exposing the holes 61 and 33, respectively, over their entire path of travel.

Um eine Kupplung zwischen der anzubauenden Schalteinrichtung und dem LS-Schalter zu erreichen, wird in das Durchgangsloch 33 der anzubauenden Schalteinrichtung ein Kopplungsteil 40 eingesetzt. Somit kann auch beim zweiten Ausführungsbeispiel ein gleichzeitiges Schalten des LS-Schalters und des angebauten Schaltgerätes erreicht werden.In order to achieve a coupling between the switching device to be mounted and the LS switch, a coupling part 40 is inserted into the through hole 33 of the switching device to be mounted. Thus, in the second embodiment, a simultaneous switching of the circuit breaker and the mounted switching device can be achieved.

Selbstverständlich kann auch bei diesem Ausführungsbeispiel auf einer Seite des LS-Schalters eine Mehrzahl von Schalteinrichtungen auf einer Seite des LS-Schalters angebaut werden, oder es können Schalteinrichtungen an beiden Seiten des LS-Schalters gleichzeitig angebaut werden.Of course, in this embodiment as well, a plurality of switching devices can be mounted on one side of the circuit breaker on one side of the circuit breaker, or switching devices on both sides of the circuit breaker can be mounted simultaneously.

Um einen Verschleiß der Kopplungsteile 40 zu minimieren, ist das Material des Kopplungsteils 40 zweckmäßigerweise Metall. Das Kopplungsteil kann daher äußerst einfach und kostengünstig in einem für die Massenfertigung geeigneten Verfahren aus einem Metallblech gestanzt werden. In einem solchen Fall ist die Grundstruktur des Kopplungsteils quaderförmig.In order to minimize wear of the coupling parts 40, the material of the coupling part 40 is expediently metal. The coupling part can therefore be extremely easily and inexpensively stamped in a suitable for mass production process from a metal sheet. In such a case, the basic structure of the coupling part is cuboid.

Anstelle des in den Fig. 1 bis 5 angewendeten Kopplungsteils sind auch andere Ausgestaltungen möglich, die einen senkrecht zur Schwenkachse 11 wirkenden Formschluß zwischen benachbarten Betätigungselementen 20 zulassen. So hat das in Fig. 6a gezeigte quaderförmige Kopplungsteil 40 am Endabschnitt 47 oberhalb und unterhalb der Symmetrieachse X Rücksprünge 44a, 44b, die einen symmetrisch auf der Symmetrieachse X gelegenen Vorsprung 42 ausbilden. Am gegenüberliegenden Endabschnitt 50 sind oberhalb und unterhalb der Symmetrieachse X Vorsprünge 41a, 41b vorgesehen, die einen symmetrisch auf der Symmetrieachse X gelegenen Rücksprung 43 ausbilden, so daß der Vorsprung 42 in den Rücksprung 43 paßt.Instead of the coupling part used in FIGS. 1 to 5, other embodiments are also possible which permit a positive engagement between adjacent actuating elements 20 which acts perpendicular to the pivot axis 11. Thus, the cuboid coupling part 40 shown in FIG. 6a has at the end section 47 above and below the axis of symmetry X recesses 44a, 44b, which form a projection 42 located symmetrically on the axis of symmetry X. At the opposite end portion 50 are above and below the axis of symmetry X projections 41 a, 41 b are provided which form a symmetrically located on the axis of symmetry X recess 43 so that the projection 42 fits into the recess 43.

Alternativ wäre auch denkbar, das Kopplungsteil 40 gemäß Fig. 6b zylinderförmig auszubilden. Demnach schließt sich am Basisabschnitt 51 ein Endabschnitt 47 an, der als ein entlang der Symmetrieachse X aus dem Basisabschnitt 51 ragender Zapfen 42 ausgebildet ist. Entsprechend ist im gegenüberliegenden Endabschnitt 50 entlang der Symmetrieachse X die Ausnehmung 43 vorgesehen. In einem solchen Fall ist die Ausnehmung 43 unabhängig von Innenwänden des Durchgangsloches 33 gebildet, so daß der senkrecht zur Schwenkachse 11 wirkende Formschluß lediglich zwischen benachbarten Kopplungsteilen 40 hergestellt ist.Alternatively, it would also be conceivable to form the coupling part 40 according to FIG. 6b in the form of a cylinder. Accordingly, an end portion 47 adjoins the base portion 51, which is formed as a pin 42 protruding along the axis of symmetry X from the base portion 51. Accordingly, the recess 43 is provided in the opposite end portion 50 along the axis of symmetry X. In such a case, the recess 43 is formed independently of inner walls of the through hole 33, so that the positive locking acting perpendicular to the pivot axis 11 is made only between adjacent coupling parts 40.
