Further disclosed is an actuation mechanism which is operatively connected to the movable contact carrier assembly to move the movable contact carrier assembly between a closed position in which the separable contacts are closed to conduct current and an open position in which the separable contacts are open. to interrupt electricity, to turn.
- An operating handle is provided for operating the operating mechanism and for setting the movable contact carrier assembly in the closed position and the open position.
- a releasable retainer is used to hold the movable contact arm when the movable contact carrier assembly is in the open position and to release the movable contact arm when the operating handle reaches the closed position.

- the invention is therefore based on the object of providing a switch lock for an electrical switch which uses as much stored energy as possible to actuate the switch shaft.
- the switch lock for an electrical switch comprises a spring, a latching mechanism and an actuating element with which a switching shaft of the electrical switch is actuated to open (OFF position) or close (ON position) the electric current, wherein when closing the electric current, the actuating element is actuated in the direction of the ON position and thereby the spring is tensioned and when the ON position is reached, the latching mechanism releases the energy of the spring to actuate the switching shaft of the electrical switch.
- the advantage here is that the maximum energy content of the spring is used.
- the latching deflects the spring to the maximum and transfers the maximum energy to the selector shaft.
- the energy of the spring is already released at approx. 70%. It is not only the energy of the spring that is used advantageously, but also the larger lever arm from the sliding axis to the spring axis, whereby a significantly higher torque is applied to the selector shaft. It is also advantageous that there are no friction-related fluctuations at the switchover point of the mechanism.
- the switching point is also independent of the operating speed of the operating element. Due to the locking mechanism, the release is not determined by an equilibrium of forces that is impaired by external influences. It is also advantageous that the switch lock can be implemented in a small installation space.
- the actuating element is designed as a rocker arm or as a rotary lever.
- the latching mechanism is activated by touching the actuating element.

- the switch lock 100 further comprises an actuating element 130.
- This can be a rocker arm 130, for example. It is also conceivable that the actuating element 130 is designed as a rotary lever.
- the switch lock 100 further comprises a spring 110 and a latching mechanism 120.
- the sequence of how the actuating element 130 actuates the switching shaft 510 of the electrical switch 500 to open (OFF position) or close (ON position) the electrical current is described below further set out.
- the spring 110 When the electrical current is closed, ie when the actuating element 130 is actuated in the direction of the ON position, the spring 110 is tensioned.
- the spring 110 serves as an energy store and, due to the latching mechanism 120, cannot yet transfer this energy to the switching shaft 510 of the electrical switch 500. Only when the ON position is reached does the latching mechanism 120 release the energy of the spring 110 to actuate the switching shaft 510 of the electrical switch 500.
- FIG. 1 the switching point U of the switch lock 100 according to the invention is shown.

- the energy for actuating the switching shaft 510 is released.
- FIG 1 a typical switchover point U SdT , as is known from the prior art, is shown.
- this switchover point is 70% of the travel of the rocker arm 130 between the OFF position and the ON position. Because the switchover point from the prior art U SdT is 70%, no further energy is built up in the spring 110 of the electrical switch 500 as a result of the movement further in the direction of the ON position. It is therefore advantageous in the case of the switch lock 100 according to the invention that the switchover point U is arranged directly at the ON position and the entire path of the rocker arm 130 is used to tension the spring 110.
- the switchover that is to say the release of the energy of the spring 110 for actuating the switching shaft 510 of the electrical switch 500, is activated by the contact of the actuating element 130 or the rocker arm 130 with the latching mechanism 120. Because the rocker arm 130 comes into mechanical contact with the latching mechanism 120, the latching mechanism 120 is activated and the switching shaft 510 is thus actuated.
- the switch lock 100 makes use of the maximum energy content of the spring 110.
- the spring 110 is deflected to the maximum by the latching mechanism 120 and the maximum energy is transmitted to the switching shaft 510 of the electrical switch 500. With conventional toggle switch locks, this is already released at around 70%.
- the release of the energy of the spring 110 is determined by the latching mechanism 120 and not via an equilibrium of forces which is subject to external influences and is impaired by them.
- the switch lock 100 according to the invention does not have any friction-related or speed-related fluctuations at the switchover point.
- the energy of the spring 110 is used to the maximum, it can be designed to be smaller and thus more economical and mechanically more stable.
- the defined amount of energy which does not experience any fluctuations due to external influences, enables closer coordination between the key switch and the shift shaft.

Description
Die Erfindung betrifft ein Schaltschloss für einen elektrischen Schalter und einen elektrischen Schalter mit solch einem Schaltschloss.The invention relates to a switch lock for an electrical switch and an electrical switch with such a switch lock.
Durch die immer höher werdenden Anforderungen an Leistungsschalter bezüglich der Baugröße, Stromtragfähigkeit usw. werden auch die Anforderungen an die innere Mechanik immer anspruchsvoller. Aus diesem Grund ist in der Bauteilauslegung speziell am Schaltschloss durch die hohe Federkraft, welche zum Schalten der Kontakte und erzeugen der Kontaktkraft bzw. des Durchdruckwinkels benötigt wird, eine physikalische Grenze erreicht.Due to the ever increasing demands on circuit breakers in terms of size, current carrying capacity, etc., the demands on the internal mechanics are also becoming more and more demanding. For this reason, a physical limit has been reached in the component design, especially on the switch lock, due to the high spring force required to switch the contacts and generate the contact force or the pressure angle.
Bisher wird in Schaltschlössern die Energie bis zum Umschaltpunkt des Schaltschlosses aufgebaut. Am Umschaltpunkt beginnt die Drehung der Schaltwelle zum Öffnen oder Schließen des elektrischen Schalters.So far, the energy is built up in switch locks up to the switching point of the switch lock. At the switching point, the switching shaft begins to rotate to open or close the electrical switch.
Um die mechanische Beanspruchung auf Bauteile so gering wie möglich zu gestalten, wird in dieser Erfindung die maximal gespeicherte Energie herangezogen zum Betätigen des Schaltschlosses.In order to make the mechanical stress on components as low as possible, the maximum stored energy is used in this invention to operate the switch mechanism.
In der
Die
In der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Schaltschloss für einen elektrischen Schalter zur Verfügung zu stellen, welches zum Betätigen der Schaltwelle so viel gespeicherte Energie wie möglich verwendet.The invention is therefore based on the object of providing a switch lock for an electrical switch which uses as much stored energy as possible to actuate the switch shaft.
Diese Aufgabe wird erfindungsgemäß durch das Schaltschloss für einen elektrischen Schalter gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Schaltschlosses sind in Unteransprüchen angegeben. Die Aufgabe wird erfindungsgemäß ebenso durch den elektrischen Schalter gemäß Anspruch 4 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen elektrischen Schalters sind in den Unteransprüchen 5 und 6 angegeben.This object is achieved according to the invention by the switch lock for an electrical switch according to claim 1. Advantageous configurations of the switch lock according to the invention are specified in the subclaims. The object is according to the invention also solved by the electrical switch according to claim 4. Advantageous refinements of the electrical switch according to the invention are specified in subclaims 5 and 6.
Das Schaltschloss für einen elektrischen Schalter gemäß Anspruch 1 umfasst eine Feder, einen Verrastmechanismus und ein Betätigungselement, mit welchem eine Schaltwelle des elektrischen Schalters betätigt wird zum Öffnen (OFF-Position) oder Schließen (ON-Position) des elektrischen Stromes, wobei beim Schließen des elektrischen Stromes das Betätigungselement in Richtung der ON-Position betätigt wird und dadurch die Feder gespannt wird und bei Erreichen der ON-Position der Verrastmechanismus die Energie der Feder freigibt zur Betätigung der Schaltwelle des elektrischen Schalters.The switch lock for an electrical switch according to claim 1 comprises a spring, a latching mechanism and an actuating element with which a switching shaft of the electrical switch is actuated to open (OFF position) or close (ON position) the electric current, wherein when closing the electric current, the actuating element is actuated in the direction of the ON position and thereby the spring is tensioned and when the ON position is reached, the latching mechanism releases the energy of the spring to actuate the switching shaft of the electrical switch.
Vorteilhaft hierbei ist, dass der maximale Energiegehalt der Feder ausgenutzt wird. Durch die Verrastung wird die Feder maximal ausgelenkt und die maximale Energie an die Schaltwelle übertragen. Bei üblichen Schaltschlössern wird die Energie der Feder bereits bei ca. 70 % freigegeben. Es wird nicht nur die Energie der Feder vorteilhaft genutzt, sondern auch der größere Hebelarm von Gleitachse bis Federachse, wodurch ein deutlich größeres Drehmoment an der Schaltwelle anliegt. Ebenso ist vorteilhaft, dass keine reibungsbedingten Schwankungen am Umschaltpunkt des Mechanismus auftreten. Auch ist der Umschaltpunkt unabhängig von der Betätigungsgeschwindigkeit des Betätigungselements. Durch die Verrastmechanismus wird die Freigabe nicht über ein Kräftegleichgewicht bestimmt, welches durch äußere Einflüsse beeinträchtigt wird. Vorteilhaft ist weiter, dass das Schaltschloss in einem geringen Bauraum umsetzbar ist. Durch die maximale Ausnutzung der Federenergie kann diese kleiner und somit günstiger und mechanisch stabiler ausgelegt werden. Ebenso vorteilhaft ist die Erhöhung der Einschaltsicherheit. Durch die definierte Energiemenge, welche keinen Schwankungen durch äußere Einflüsse unterliegt, ist eine genauere Abstimmung zwischen Schaltschloss und Schaltwelle gegeben.The advantage here is that the maximum energy content of the spring is used. The latching deflects the spring to the maximum and transfers the maximum energy to the selector shaft. With conventional switch locks, the energy of the spring is already released at approx. 70%. It is not only the energy of the spring that is used advantageously, but also the larger lever arm from the sliding axis to the spring axis, whereby a significantly higher torque is applied to the selector shaft. It is also advantageous that there are no friction-related fluctuations at the switchover point of the mechanism. The switching point is also independent of the operating speed of the operating element. Due to the locking mechanism, the release is not determined by an equilibrium of forces that is impaired by external influences. It is also advantageous that the switch lock can be implemented in a small installation space. Due to the maximum utilization of the spring energy, it can be designed to be smaller and therefore cheaper and more mechanically stable. The increase in switch-on reliability is just as advantageous. Due to the defined amount of energy, which does not fluctuate due to external influences is subject, a more precise coordination between the key switch and the shift shaft is given.
In einer Ausgestaltung ist das Betätigungselement als Kipphebel oder als Drehhebel ausgebildet.In one embodiment, the actuating element is designed as a rocker arm or as a rotary lever.
In einer weiteren Ausgestaltung wird der Verrastmechanismus durch Berührung des Betätigungselements aktiviert.In a further embodiment, the latching mechanism is activated by touching the actuating element.
Die Aufgabe wird erfindungsgemäß ebenso durch den elektrischen Schalter gemäß Anspruch 4 gelöst, der ein erfindungsgemäßes Schaltschloss umfasst und eine Schaltwelle, wobei die Schaltwelle betätigbar ist von der Energie der Feder.The object is also achieved according to the invention by the electrical switch according to claim 4, which comprises a switch lock according to the invention and a switch shaft, the switch shaft being actuatable by the energy of the spring.
In einer Ausgestaltung des elektrischen Schalters gibt bei Erreichen der ON-Position der Verrastmechanismus die Energie der Feder frei zur Betätigung der Schaltwelle des elektrischen Schalters und die Schaltwelle bringt mindestens einen Bewegkontakt mit einem Festkontakt in mechanischen Kontakt.In one embodiment of the electrical switch, when the ON position is reached, the latching mechanism releases the energy of the spring to actuate the switching shaft of the electrical switch and the switching shaft brings at least one moving contact into mechanical contact with a fixed contact.
In einer weiteren Ausgestaltung ist der elektrische Schalter als Leistungsschalter ausgebildet.In a further embodiment, the electrical switch is designed as a power switch.
