Definitions
- a generic switch lock comprises a switching device for opening and closing a contact element which is in effect with a clamping element and a unlatching mechanism, by means of which the clamping element can be converted from a stressed state into an at least largely unrestrained state on the basis of a triggering signal.
- Circuit breakers are special switches that are usually designed for high currents. These switches can not only switch operating currents and low overload currents, but also switch on high overload currents and short-circuit currents if faults occur, hold these fault currents for a predetermined time and then switch them off again. Depending on the embodiment, circuit breakers are single-pole or multi-pole.
- Such circuit breakers regularly have so-called switching locks, which cause the switching off of a circuit when unwanted operating conditions, in particular short circuits, occur.
- a switch lock represents a mechanical device, which preferably enables the switching off of a circuit.
- the force of a tensioned spring is usually released to open the switch contact, which has been stretched when switching on a clamping mechanism.
- the typical trigger criterion is a current of a predetermined current, through which the lock is released by means of an electromagnet or a heating bimetallic strip.
- the circuit breaker of a circuit breaker has two main areas. On the one hand is a switching mechanism provided, acted upon by the spring force, the opening and closing of an electrical switching contact is realized. On the other hand, such a switching mechanism has a Entklinkungsmechanismus that releases the energy stored in a spring of the switching mechanism upon reaching a triggering criterion, whereby the switching mechanism is triggered and the electrical switching contact is opened.
- the problem of the invention is the object of developing a Entklinkungsmechanismus a switching mechanism such that within a limited space, the force of the switching mechanism is minimized by the largest possible factor.
- the decoupling mechanism to be specified should be characterized by a high release safety, which should be ensured, above all, by a low degree of friction within the unlatching mechanism.
- Essential for a high release safety on the one hand that the release force is not too large and on the other hand, the release force remains approximately constant even after prolonged operation of the switch lock.
- the unlatching mechanism should be designed such that the switch lock can be used both for single-pole switches, in which only small forces in the switching mechanism, as well as multi-pole switches with high forces in the switching mechanism.
- the invention relates to a circuit breaker with a switch lock, on the one hand has a switching device for opening and closing a standing with a clamping element operatively connected switch contact and on the other hand a Entklinkungsmechanismus, on the basis of a trigger signal, the clamping element from a tensioned in an at least substantially unstressed state can be converted, that the switching contact is thereby opened.
- the tensioning element is coupled to a tensioning lever, which is locked by a detent pawl of Entklinkungsmechanismus abuts against a stop surface of the tensioning lever and prevents it from moving, so that the spring element in tensioned Condition is maintained.
- the switching mechanism has been developed such that the stop surface is curved and arranged to be movable relative to the clamping lever.
- the execution of the abutment surface with a curved in the direction of the pawl outer contour at the same time movable mounting of the stop surface has the advantage that no flat contact surface between the pawl and the clamping lever exists, the pawl when triggering the switching mechanism relatively low friction moves over the stop surface and so Wear phenomena are minimized. In particular, it is ensured in this way that the pawl with different areas of the stop surface can be brought into contact and preferably only rolling friction between pawl and stop surface is formed.
- the outer circumferential surface of a roller forms the stop surface.
- the roller is preferably rotatably mounted on the clamping lever.
- the end of the pawl contacts the abutment surface, ie the outer peripheral surface of the roller.
- the switch lock triggers, the pawl is moved so that the force introduced via the pawl in the role of the clamping lever decreases, so that finally sets the clamping lever in motion and rolls the end of the pawl over the outer peripheral surface of the roller. The resulting friction is minimal.
- the clamping lever is made in one piece and the roller rotatably mounted in a suitable recess by means of a bearing pin.
- an alternative design provides that the clamping lever is designed in several parts, wherein in particular two planar-parallel plates, which are contoured in a suitable manner, are provided, and between these sheets, the roller is rotatably mounted about a bearing pin.
- the stop surface and / or the free end of the pawl is provided with a surface coating.
- a surface coating has a high wear resistance or ensures that the friction between the end of the pawl and the stop surface is at least minimized.
- a roller whose outer peripheral surface forms the abutment surface is provided, it can be designed either as a sheet metal or as a plastic roller (ceramic materials, etc.). In a preferred manner, the roller is manufactured as a turned part.
- the switching mechanism embodied according to the invention is therefore characterized in particular by the fact that in the unlatching mechanism, a stop surface curved in the direction of the free end of the pawl and movably arranged relative to the tensioning lever is provided. Preferably, in the locked state of the lock, a roller whose outer peripheral surface forms the abutment surface is engaged with the end of the pawl.
- the solution according to the invention is characterized in that, despite the comparatively small size, the release force required for triggering the lock is minimized.
- the switching mechanism designed according to the invention can thus be used in the same way for both single-pole and three-pole or four-pole switches. This is primarily due to the fact that the function of the unlatching mechanism is at least largely independent of the force in the switching mechanism.
- FIG. 1 shows in a perspective view of the switching mechanism 1 of a circuit breaker.
- the switching mechanism 1 shown here has two main components, namely the switching mechanism 2 on the one hand and the Entklinkungsmechanismus 3 on the other.
- the switching mechanism 2 is the electrical switching contact of the circuit breaker in such a way with a spring used as an energy storage 4 in operative connection that when the contact is closed, the spring 4 is tensioned and when the switching mechanism 1, the energy stored in the spring 4 is released, so that the contact is opened by acting on him spring force.
- the Entklinkungsmechanismus 3 is provided.
- connection between the switching mechanism 2 with tension spring 4 and the Entklinkungsmechanismus 3 is made via a clamping lever 5, which can be locked or released by the Entklinkungsmechanismus 3 as needed.
- a clamping lever 5 which can be locked or released by the Entklinkungsmechanismus 3 as needed.
- An essential component of Entklinkungsmechanismus 3 is the pawl spring 10, which acts on the pawl 8 so that the end of the pawl 8 is moved against a designated stop surface of the clamping lever 5 for locking the clamping lever 5. Furthermore, in the unlatching mechanism 3, a triggering shaft 9 is provided which, upon reaching a triggering criterion, in particular as soon as the current in the switch reaches a predetermined current, is put into a rotary or pivoting movement. By the movement of the trip shaft 9, this device so in contact with the pawl 8, that also the pawl 8 is pivoted and so the force acting from the end of the pawl 8 on the stop surface of the clamping lever 5 force is reduced.
- FIGS. 2 to 5 is the switching mechanism 1, whose components are already in FIG. 1 has been explained in more detail, shown in an on position.
- the FIGS. 2 and 3 show the switch lock in a side view, the 4 and 5 in a perspective view, wherein the FIG. 3 and 5 show the switch lock each in a cutaway view.
- the switching mechanism 1 is divided along the plane of symmetry and in each case only the components provided in the rear part are shown. This way, in the FIG. 3 and 5 the rear side part 14 of the clamping lever 5, the roller 7 mounted thereon and the end 12 of the pawl 8 visible.
- the Entklinkungsmechanismus 3 and thus also the switching mechanism 1 is in a stretched state, wherein the end 12 of the pawl 8 touches the outer periphery of a rotatably mounted on the clamping lever 5 roller 7 in the region of the stop surface 13.
- the pawl 8 of the clamping lever 5 With the help of the pawl 8 of the clamping lever 5 is thus locked in the position shown, so that the spring 4 is tensioned and the electrical switching contact is closed.
- FIG. 6 shows a side view of the switching mechanism 1 in an operating state in which this is triggered.
- the tripping shaft 9 is operated on the basis of a trigger signal, so that the pawl 8 counterclockwise from the Roller 7 is moved away. Then, the force with which the pawl 8 acts on the stop surface 13 of the roller 7 is reduced, the pawl 8 loses contact with the roller 7 and finally slips off the roller 7.
- the tensioning lever 5 finally also performs a pivoting or pivoting movement in the counterclockwise direction, whereby the spring 4 is transferred to a relaxed state and thereby the electrical switching contact is opened.
- FIGS. 7 and 8 now show the switching mechanism 1 of a circuit breaker in tripped position.
- This position of a switching mechanism 1 is also referred to as a trip position.
- the tensioning lever 5 with the roller 7 rotatably mounted thereon has been transferred to its end position upwards. In this case, he is on a clamping bolt 11 which is mounted in the shift lever 6, on. If the switching mechanism 1 is to be transferred from the trip position back to the on position, with respect to the switching mechanism 1, in particular the Entklinkungsmechanismus 3 a reset must be performed so that the Entklinkungsmechanismus 3 and here in particular the pawl spring 10 tensioned and the trip shaft 9 is reset to its original position.
- FIGS. 9 to 11 is a known from the prior art latch compared with an inventively executed.
- FIG. 3 shown side view of the arranged in the rear part of the switching mechanism 1 components.
- the invention is characterized in particular by an advantageous design of the clamping lever side provided stop surface 13.
- FIGS. 9 to 11 is a section of the switching mechanism 1 is shown in detail. This show the FIGS. 9 to 11 in each case the lying in the region of the Entklinkungsmechanismus 3 end of the clamping lever 5 with its stop surface 13 and the pawl 8.
- the hereby in contact FIGS. 9 and 10 show in this context known from the prior art support the Pawl 8 on the stop surface 13 of the clamping lever 5.
- an inventively executed latch which is realized by the use of a movably arranged curved stop surface 13, which is realized in this case by using the outer peripheral surface of a rotatably mounted on the clamping lever 5 roller 7.
- FIG. 9 is a latch, as known from the prior art, shown in new condition. Between the end 12 of the pawl 8 and the stop surface 13, a flat contact surface is provided in this case. Furthermore, the vector of the release force F NVar , in the normal direction, that is perpendicular to the stop surface 13, and the lever arm h between the normal vector and a point K, by which the pawl 8 is rotated or pivoted, shown.
- FIG. 10 shows the well-known support after a certain period of operation. It is essential that a certain wear has occurred due to the friction between the end 12 of the pawl 8 and the stop surface 13 on the stop surface 13 and the clamping lever 8. Due to the abrasion, the contour of the clamping lever 8 is slightly flattened in the region of the stop surface 13 with respect to the initial state. By this friction-related flattening of the contour of the clamping lever, the direction of the normal force F Nvarr changes, which in turn increases the release force of the switching mechanism 1 relative to the initial state.
- FIG. 11 is now an embodiment of the invention Verklinkung a switching mechanism 1 shown.
- the end 12 of the pawl 8 with the outer peripheral surface of a rotatably mounted on the clamping lever 5 roller 7 is engaged.
- the use of a roller, by which a movable, outwardly curved stop surface 13 is realized, has the particular advantage that the wear on the supporting components is significantly reduced. Furthermore, the angle of the resulting normal force F N is held approximately constant by the support on the roller 7, so that the release force range is relatively small and does not increase with increasing life of the components.
- FIG. 12 shows in a perspective detail view of an inventively designed clamping lever 5, which creates a connection between the spring element 4 of the switching mechanism 2 and the Entklinkungsmechanismus 3.
- the tensioning lever 5 is designed substantially in two parts and has two plane-parallel clamping lever, in particular, this is 2 identical components, between which further components are arranged.
- a roller 7 is provided which is rotatably supported in the clamping lever 5 via two bearing pins 16.
- the roller 7 designed as a rotating part has an outer circumferential surface, which is used as a stop surface 13 for the pawl 8.
- R represents the roller outer radius and the roller bearing radius.

Description
Die Erfindung betrifft einen Leistungsschalter mit einem Schaltschloss. Ein gattungsgemäßes Schaltschloss weist eine Schalteinrichtung zum Öffnen und Schließen eines mit einem Spannelement in Wirkung stehenden Schaltkontaktes und einen Entklinkungsmechanismus, durch den auf der Grundlage eines Auslösesignals das Spannelement aus einem gespannten in einen zumindest weitgehend ungespannten Zustand überführbar ist.The invention relates to a circuit breaker with a switching mechanism. A generic switch lock comprises a switching device for opening and closing a contact element which is in effect with a clamping element and a unlatching mechanism, by means of which the clamping element can be converted from a stressed state into an at least largely unrestrained state on the basis of a triggering signal.
Leistungsschalter sind spezielle Schalter, die üblicherweise für hohe Ströme ausgelegt sind. Diese Schalter können nicht nur Betriebsströme und geringe Überlastströme schalten, sondern bei auftretenden Fehlern auch hohe Überlastströme und Kurzschlussströme einschalten, diese Fehlerströme eine vorgegebene Zeit halten und wieder ausschalten. Je nach Ausführungsform sind Leistungsschalter einpolig oder mehrpolig ausgeführt.Circuit breakers are special switches that are usually designed for high currents. These switches can not only switch operating currents and low overload currents, but also switch on high overload currents and short-circuit currents if faults occur, hold these fault currents for a predetermined time and then switch them off again. Depending on the embodiment, circuit breakers are single-pole or multi-pole.
Derartige Leistungsschalter verfügen regelmäßig über so genannte Schaltschlösser, die bei Auftreten ungewollter Betriebszustände, insbesondere bei Kurzschlüssen, das Abschalten eines Stromkreises bewirken.Such circuit breakers regularly have so-called switching locks, which cause the switching off of a circuit when unwanted operating conditions, in particular short circuits, occur.
Ein Schaltschloss stellt eine mechanische Vorrichtung dar, die vorzugsweise das Abschalten eines Stromkreises ermöglicht. Hierzu wird zum Öffnen des Schaltkontakts üblicherweise die Kraft einer gespannten Feder freigegeben, die beim Einschalten über einen Spannmechanismus gespannt worden ist. Das typische Auslösekriterium ist ein Strom einer vorgebbaren Stromstärke, durch den die Arretierung mit Hilfe eines Elektromagneten oder eines sich erhitzenden Bimetallstreifens gelöst wird.A switch lock represents a mechanical device, which preferably enables the switching off of a circuit. For this purpose, the force of a tensioned spring is usually released to open the switch contact, which has been stretched when switching on a clamping mechanism. The typical trigger criterion is a current of a predetermined current, through which the lock is released by means of an electromagnet or a heating bimetallic strip.
Das Schaltschloss eines Leistungsschalters verfügt über zwei wesentliche Bereiche. Einerseits ist ein Schaltmechanismus vorgesehen, über den Federkraft beaufschlagt das Öffnen und Schließen eines elektrischen Schaltkontaktes realisiert wird. Andererseits verfügt ein derartiges Schaltschloss über einen Entklinkungsmechanismus, der bei Erreichen eines Auslösekriteriums die in einer Feder des Schaltmechanismus gespeicherte Energie freigibt, wodurch das Schaltschloss ausgelöst und der elektrische Schaltkontakt geöffnet wird.The circuit breaker of a circuit breaker has two main areas. On the one hand is a switching mechanism provided, acted upon by the spring force, the opening and closing of an electrical switching contact is realized. On the other hand, such a switching mechanism has a Entklinkungsmechanismus that releases the energy stored in a spring of the switching mechanism upon reaching a triggering criterion, whereby the switching mechanism is triggered and the electrical switching contact is opened.
Problematisch an den aus dem Stand der Technik bekannten Schaltschlössern ist vielfach, dass die innerhalb des Entklinkungsmechanismus vorgesehene Sperrklinke im gesperrten Zustand mit einer ebenen Fläche der Außenkontur des mit der Feder in Wirkverbindung stehenden Spannhebels in Kontakt gebracht wird. Da die Sperrklinke während des Betriebs des Leistungsschalters auf diese Weise immer wieder den gleichen Bereich der Anschlagfläche des Spannhebels berührt, kommt es hier mit zunehmender Betriebsdauer zu Verschleißerscheinungen. Aufgrund dieses Abriebs an der Anschlagfläche ändern sich die Richtung der Normalkraft und damit auch das über die Sperrklinke in die Anschlagfläche des Spannhebels eingeleitete Drehmoment. Eine Drehmomenterhöhung in diesem Bereich hat wiederum die Folge, dass sich die für eine Auslösung des Schaltschlosses benötigte Kraft erhöht. Zwar ist es denkbar, den Verschleiß durch Verwendung von Werkstoffen höherer Härte oder durch Einsatz von Verfahren zur Oberflächenbehandlung zu verringern, doch würde dies die Herstellungskosten eines entsprechenden Bauteils erhöhen. Eine weitere Möglichkeit, den Abrieb an der Anschlagfläche zu verringern, besteht darin, eine vollflächige Auflage zwischen Sperrklinke und Anschlagfläche des Spannhebels zu realisieren. Allerdings hat dies den Nachteil, dass der Hebelarm der Normalenkraft, also der Abstand zwischen dem Normalkraftvektor und dem Kraft einleitenden Bereich der Sperrklinke, variieren kann, was zu Schwankungen der für eine Auslösung des Schaltschlosses benötigten Kraft führen würde.The problem with the known from the prior art switch locks is often that provided within the Entklinkungsmechanismus pawl in the locked state with a flat surface of the outer contour of the spring operatively connected to the clamping lever is brought into contact. Since the pawl during operation of the circuit breaker in this way repeatedly touches the same area of the stop surface of the clamping lever, it comes here with increasing operating time to wear. Due to this abrasion on the stop surface, the direction of the normal force and thus also the torque introduced via the pawl into the stop face of the clamping lever change. An increase in torque in this area in turn has the consequence that increases the force required for triggering the switching mechanism. Although it is conceivable to reduce wear by using materials of higher hardness or by using surface treatment methods, this would increase the manufacturing costs of a corresponding component. Another way to reduce the abrasion on the stop surface, is to realize a full-surface contact between pawl and stop surface of the clamping lever. However, this has the disadvantage that the lever arm of the normal force, so the distance between the normal force vector and the force-introducing portion of the pawl, may vary, which would lead to variations in the force required for triggering the switching mechanism.
Ausgehend von den aus dem Stand der Technik bekannten Schaltschlössern für Leistungsschalter sowie dem geschilderten Problem liegt der Erfindung die Aufgabe zugrunde, einen Entklinkungsmechanismus eines Schaltschlosses derart weiterzubilden, dass innerhalb eines begrenzten Bauraums die Kraft des Schaltmechanismus um einen möglichst großen Faktor minimiert wird. Hierbei soll sich der anzugebende Entklinkungsmechanismus durch eine hohe Loslaufsicherheit auszeichnen, die vor allem durch eine geringe Reibung innerhalb des Entklinkungsmechanismus sichergestellt werden soll. Wesentlich für eine hohe Loslaufsicherheit ist einerseits, dass die Auslösekraft nicht zu große ist und andererseits die Auslösekraft auch nach längerer Betriebsdauer des Schaltschlosses annähernd konstant bleibt. Insbesondere soll sichergestellt werden, dass das Auslösen des Schaltschlosses unabhängig von der Kraft im Schaltmechanismus möglich ist. Des Weiteren soll der Entklinkungsmechanismus derart ausgeführt werden, dass das Schaltschloss sowohl für einpolige Schalter, bei denen nur geringe Kräfte im Schaltmechanismus auftreten, als auch für mehrpolige Schalter mit hohen Kräften im Schaltmechanismus verwendet werden kann.Based on the known from the prior art switch locks for circuit breakers and the described The problem of the invention is the object of developing a Entklinkungsmechanismus a switching mechanism such that within a limited space, the force of the switching mechanism is minimized by the largest possible factor. Here, the decoupling mechanism to be specified should be characterized by a high release safety, which should be ensured, above all, by a low degree of friction within the unlatching mechanism. Essential for a high release safety on the one hand, that the release force is not too large and on the other hand, the release force remains approximately constant even after prolonged operation of the switch lock. In particular, it should be ensured that the triggering of the switching mechanism is possible regardless of the force in the switching mechanism. Furthermore, the unlatching mechanism should be designed such that the switch lock can be used both for single-pole switches, in which only small forces in the switching mechanism, as well as multi-pole switches with high forces in the switching mechanism.
Die vorstehende Aufgabe wird mit einem Leistungsschalter mit Schaltschloss gemäß Anspruch 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der abhängigen Ansprüche und werden in der folgenden Beschreibung unter teilweiser Bezugnahme auf die FIGen näher erläutert.The above object is achieved with a circuit breaker with switching mechanism according to claim 1. Advantageous embodiments of the invention are the subject of the dependent claims and will be explained in more detail in the following description with partial reference to the figures.
Die Erfindung betrifft einen Leistungsschalter mit einem Schaltschloss, das einerseits eine Schalteinrichtung zum Öffnen und Schließen eines mit einem Spannelement in Wirkverbindung stehenden Schaltkontakts und andererseits einen Entklinkungsmechanismus aufweist, durch den auf der Grundlage eines Auslösesignals das Spannelement derart aus einem gespannten in einen zumindest weitgehend ungespannten Zustand überführbar ist, dass der Schaltkontakt hierdurch geöffnet wird. Das Spannelement ist an einen Spannhebel gekoppelt, der gesperrt wird, indem eine Sperrklinke des Entklinkungsmechanismus an einer Anschlagfläche des Spannhebels anliegt und diesen an einer Bewegung hindert, so dass das Federelement in gespannten Zustand gehalten wird. Erfindungsgemäß ist das Schaltschloss derart weitergebildet worden, dass die Anschlagfläche gewölbt ausgeführt und relativ zum Spannhebel beweglich angeordnet ist.The invention relates to a circuit breaker with a switch lock, on the one hand has a switching device for opening and closing a standing with a clamping element operatively connected switch contact and on the other hand a Entklinkungsmechanismus, on the basis of a trigger signal, the clamping element from a tensioned in an at least substantially unstressed state can be converted, that the switching contact is thereby opened. The tensioning element is coupled to a tensioning lever, which is locked by a detent pawl of Entklinkungsmechanismus abuts against a stop surface of the tensioning lever and prevents it from moving, so that the spring element in tensioned Condition is maintained. According to the switching mechanism has been developed such that the stop surface is curved and arranged to be movable relative to the clamping lever.
Die Ausführung der Anschlagfläche mit einer in Richtung der Sperrklinke gewölbten Außenkontur bei gleichzeitig beweglicher Lagerung der Anschlagfläche hat hierbei den Vorteil, dass keine ebene Kontaktfläche zwischen der Sperrklinke und dem Spannhebel existiert, die Sperrklinke sich beim Auslösen des Schaltschlosses vergleichsweise reibungsarm über die Anschlagfläche bewegt und so Verschleißerscheinungen minimiert werden. Insbesondere wird auf diese Weise sichergestellt, dass die Sperrklinke mit unterschiedlichen Bereichen der Anschlagfläche in Kontakt bringbar ist und sich vorzugsweise lediglich Rollreibung zwischen Sperrklinke und Anschlagfläche ausbildet.The execution of the abutment surface with a curved in the direction of the pawl outer contour at the same time movable mounting of the stop surface has the advantage that no flat contact surface between the pawl and the clamping lever exists, the pawl when triggering the switching mechanism relatively low friction moves over the stop surface and so Wear phenomena are minimized. In particular, it is ensured in this way that the pawl with different areas of the stop surface can be brought into contact and preferably only rolling friction between pawl and stop surface is formed.
In einer speziellen Ausführungsform der Erfindung bildet die äußere Umfangsfläche einer Rolle die Anschlagfläche. Die Rolle ist vorzugsweise drehbar am Spannhebel gelagert. In gesperrtem Zustand des Schaltschlosses berührt das Ende der Sperrklinke die Anschlagfläche, also die äußere Umfangsfläche der Rolle. Sobald das Schaltschloss auslöst, wird die Sperrklinke derart bewegt, dass die über die Klinke in die Rolle des Spannhebels eingeleitete Kraft abnimmt, so dass sich schließlich der Spannhebel in Bewegung setzt und das Ende der Sperrklinke über die äußere Umfangsfläche der Rolle abrollt. Die hierbei entstehende Reibung ist minimal.In a specific embodiment of the invention, the outer circumferential surface of a roller forms the stop surface. The roller is preferably rotatably mounted on the clamping lever. In the locked state of the switching mechanism, the end of the pawl contacts the abutment surface, ie the outer peripheral surface of the roller. Once the switch lock triggers, the pawl is moved so that the force introduced via the pawl in the role of the clamping lever decreases, so that finally sets the clamping lever in motion and rolls the end of the pawl over the outer peripheral surface of the roller. The resulting friction is minimal.
Die Lagerung der zuvor beschriebenen Rolle eines Entklinkungsmechanismus kann bevorzugt auf zwei unterschiedliche Arten erfolgen. In einer ersten speziellen Weiterbildung der Erfindung ist der Spannhebel einteilig ausgeführt und die Rolle in einer geeigneten Ausnehmung mit Hilfe eines Lagerbolzens drehbar gelagert. Eine alternative Gestaltung sieht demgegenüber vor, dass der Spannhebel mehrteilig ausgeführt ist, wobei insbesondere zwei planparallel angeordnete Bleche, die in geeigneter Weise konturiert sind, vorgesehen sind, und zwischen diesen Blechen die Rolle um einen Lagerbolzen drehbar gelagert ist.The storage of the above-described role of a unlatching mechanism can preferably be done in two different ways. In a first specific embodiment of the invention, the clamping lever is made in one piece and the roller rotatably mounted in a suitable recess by means of a bearing pin. In contrast, an alternative design provides that the clamping lever is designed in several parts, wherein in particular two planar-parallel plates, which are contoured in a suitable manner, are provided, and between these sheets, the roller is rotatably mounted about a bearing pin.
Gemäß einer weiteren speziellen Ausführungsform der Erfindung ist es denkbar, dass die Anschlagfläche und/oder das freie Ende der Sperrklinke mit einer Oberflächenbeschichtung versehen ist. Vorzugsweise weist eine derartige Beschichtung eine hohe Verschleißfestigkeit aus oder stellt sicher, dass die Reibung zwischen dem Ende der Sperrklinke und der Anschlagfläche zumindest minimiert wird. Sofern eine Rolle, deren äußere Umfangsfläche die Anschlagfläche bildet, vorgesehen ist, kann diese entweder als Blech- oder als Kunststoffrolle (Keramikwerkstoffe usw.) ausgeführt sein. Auf bevorzugte Weise wird die Rolle als Drehteil gefertigt.According to another specific embodiment of the invention, it is conceivable that the stop surface and / or the free end of the pawl is provided with a surface coating. Preferably, such a coating has a high wear resistance or ensures that the friction between the end of the pawl and the stop surface is at least minimized. If a roller whose outer peripheral surface forms the abutment surface is provided, it can be designed either as a sheet metal or as a plastic roller (ceramic materials, etc.). In a preferred manner, the roller is manufactured as a turned part.
Das erfindungsgemäß ausgeführte Schaltschloss zeichnet sich somit vor allem dadurch aus, dass im Entklinkungsmechanismus eine in Richtung des freien Endes der Sperrklinke gewölbte und relativ zum Spannhebel beweglich angeordnete Anschlagfläche vorgesehen ist. Bevorzugt wird in gesperrtem Zustand des Schlosses eine Rolle, deren äußere Umfangsfläche die Anschlagfläche bildet, mit dem Ende der Sperrklinke in Eingriff gebracht. Die erfindungsgemäße Lösung zeichnet sich hierbei dadurch aus, dass trotz vergleichsweise kleiner Baugröße die für die Auslösung des Schlosses benötigte Auslösekraft minimiert wird. Das erfindungsgemäß ausgeführte Schaltschloss kann somit auf gleiche Weise sowohl für ein- wie auch drei - oder vierpolige Schalter verwendet werden. Dies ist vor allem darauf zurückzuführen, dass die Funktion des Entklinkungsmechanismus zumindest weitgehend von der Kraft im Schaltmechanismus unabhängig ist.The switching mechanism embodied according to the invention is therefore characterized in particular by the fact that in the unlatching mechanism, a stop surface curved in the direction of the free end of the pawl and movably arranged relative to the tensioning lever is provided. Preferably, in the locked state of the lock, a roller whose outer peripheral surface forms the abutment surface is engaged with the end of the pawl. The solution according to the invention is characterized in that, despite the comparatively small size, the release force required for triggering the lock is minimized. The switching mechanism designed according to the invention can thus be used in the same way for both single-pole and three-pole or four-pole switches. This is primarily due to the fact that the function of the unlatching mechanism is at least largely independent of the force in the switching mechanism.
Durch die bewegliche Anschlagfläche am Spannhebel, bevorzugt eine Rolle, wird die Reibung, die beim Abrutschen der Sperrklinke vom Spannhebel entsteht, gegenüber den bekannten Lösungen verringert. Aufgrund einer vereinfachten Betrachtung kann in diesem Fall davon ausgegangen werden, dass der Einfluss der Reibung um einen Faktor R/r, wobei R den Rollenaußenradius und r den Rollenlagerradius repräsentiert, reduziert wird. Wird beispielsweise eine Rolle mit einem Außenradius von 5,4 cm und einem Rollenlagerradius von 1,7 cm verwendet, ergibt sich hieraus ein Faktor von 3,8, also eine deutliche Verringerung des Reibwiderstandes. Durch diese starke Minimierung des Reibungseinflusses wird einerseits die Loslaufsicherheit des Schaltschlosses erhöht und andererseits können die Hebelverhältnisse im Entklinkungsmechanismus derart angepasst werden, dass die Untersetzung der Kraft vom Schaltmechanismus bis zur Auslösewelle des Entklinkungsmechanismus sehr groß ist und somit zum Auslösen des Schaltschlosses nur eine sehr kleine Kraft benötigt wird.Due to the movable stop surface on the clamping lever, preferably a roller, the friction that arises when slipping the pawl from the clamping lever, compared to the known solutions is reduced. On the basis of a simplified consideration, it can be assumed in this case that the influence of the friction is by a factor R / r, where R is the outer roll radius and r represents the roller bearing radius is reduced. For example, if a roller with an outer radius of 5.4 cm and a roller bearing radius of 1.7 cm used, this results in a factor of 3.8, so a significant reduction in the frictional resistance. By this strong minimization of the influence of friction on the one hand, the release safety of the switching mechanism is increased and on the other hand, the lever ratios in Entklinkungsmechanismus be adjusted so that the reduction of the force from the switching mechanism to the trigger shaft of Entklinkungsmechanismus is very large and thus to trigger the switching mechanism only a very small force is needed.

Um die Feder 4 einerseits zuverlässig im gespannten Zustand halten und andererseits ein zuverlässiges sowie schnelles Auslösen des Schaltschlosses sicherstellen zu können, ist der Entklinkungsmechanismus 3 vorgesehen.To keep the spring 4 on the one hand reliably in the tensioned state and on the other hand to ensure reliable and rapid release of the switching mechanism, the Entklinkungsmechanismus 3 is provided.
Die Verbindung zwischen dem Schaltmechanismus 2 mit Spannfeder 4 und dem Entklinkungsmechanismus 3 wird über einen Spannhebel 5 hergestellt, der durch den Entklinkungsmechanismus 3 bedarfsgerecht gesperrt oder freigegeben werden kann. Sobald der Spannhebel 5 vom Entklinkungsmechanismus 3 freigegeben wird, entspannt sich die Feder 4 und der elektrische Schaltkontakt wird geöffnet.The connection between the
Ein wesentliches Bauteil des Entklinkungsmechanismus 3 stellt die Klinkenfeder 10 dar, die derart auf die Sperrklinke 8 einwirkt, dass das Ende der Sperrklinke 8 gegen eine hierfür vorgesehene Anschlagfläche des Spannhebels 5 zur Arretierung des Spannhebels 5 bewegt wird. Des Weiteren ist im Entklinkungsmechanismus 3 eine Auslösewelle 9 vorgesehen, die bei Erreichen eines Auslösekriteriums, insbesondere sobald der Strom im Schalter eine vorgegebene Stromstärke erreicht, in eine Dreh- bzw. Schwenkbewegung versetzt wird. Durch die Bewegung der Auslösewelle 9 gerät diese derart in Kontakt mit der Sperrklinke 8, dass auch die Sperrklinke 8 geschwenkt und so die vom Ende der Sperrklinke 8 auf die Anschlagfläche des Spannhebels 5 wirkende Kraft verringert wird. Die Verringerung der von der Sperrklinke 8 auf die Anschlagfläche des Spannhebels 5 wirkenden Kraft führt im Weiteren dazu, dass die Arretierung des Spannhebels 5 gelöst, die Feder 4 entspannt und der Schaltkontakt geöffnet werden. Im Folgenden werden die verschiedenen Schaltzustände des Schaltschlosses 1 eingehend erläutert.An essential component of Entklinkungsmechanismus 3 is the

In EIN-Position ist der Schalter geschlossen, die Feder 4 gespannt und das Schaltschloss 1 in gesperrtem Zustand.In the ON position, the switch is closed, the spring 4 is tensioned and the switch lock 1 is in the locked state.
Ferner befindet sich der Entklinkungsmechanismus 3 und somit auch das Schaltschloss 1 in gespanntem Zustand, wobei das Ende 12 der Sperrklinke 8 den Außenumfang einer am Spannhebel 5 drehbar gelagerten Rolle 7 im Bereich der Anschlagfläche 13 berührt. Mit Hilfe der Sperrklinke 8 ist der Spannhebel 5 somit in der dargestellten Position arretiert, so dass die Feder 4 gespannt und der elektrische Schaltkontakt geschlossen ist.Furthermore, the Entklinkungsmechanismus 3 and thus also the switching mechanism 1 is in a stretched state, wherein the

In Ergänzung hierzu zeigt
Der zuvor beschriebene Effekt kann bislang lediglich durch die Verwendung von Werkstoffen höherer Härte spezieller Oberflächenbehandlung bzw. durch Einsatz von Schmiermitteln reduziert werden. Dies würde allerdings die Kosten erhöhen bei gleichzeitig eingeschränkter Funktionssicherheit und Einsatzbereich. Eine weitere Möglichkeit zur Reduzierung des Abriebs besteht in der vollflächigen Auflage der Bauteile. Diese technische Lösung hat jedoch den Nachteil, dass der Hebelarm der Normalkraft und somit die für die Auslösung des Schaltschlosses 1 benötigte Kraft variieren kann.The effect described above can hitherto only be reduced by the use of materials of higher hardness of special surface treatment or by the use of lubricants. However, this would increase the costs while at the same time limiting functional reliability and area of application. Another way to reduce abrasion is the full-surface support of the components. However, this technical solution has the disadvantage that the lever arm the normal force and thus the force required to trigger the switching mechanism 1 can vary.
