- the connecting element 6 is soldered, on the one hand, to the connecting lug 9 of the second pole of the varistor 3 and, on the other hand, to the end of the rigid connecting element 11 facing away from the second connecting contact 5, so that the second connecting contact 5 in the case of existing solder connections via the connecting element 11, Connecting element 6 and the terminal lug 9 is connected to the second pole of the varistor 3. Due to the robust design of these current-carrying mechanical parts, as already explained, even large pulse currents can be safely transmitted and thus dissipated.
- the connecting element 6 is pushed by the force of the spring system 7 from the contact position up and at the same time the insulating separating element 10 is inserted into the intermediate space between the connecting lug 9 and the rigid connecting element 11.
- An emerging when opening the separation point arc is thus deleted directly by the retracting into the separation point insulating separator 10 so that a high insulation and tracking resistance and rapid quenching of an arc can be ensured without the distance between the terminal lug 9 of the second pole and the associated terminal contact 5 and the connection element 11 must be increased.
- the overvoltage protection element 1 can thus have relatively small dimensions, so that it is particularly suitable as a plug part in a latched onto a mounting rail device base. Since not the connection element 11 but only the connecting element 6 is moved, the connecting element 11 designed as a connection angle can be designed to be correspondingly robust and with a sufficiently large cross section.

- the separating element 10 entering the intermediate space interrupts the electrical connection between the second pole of the varistor 3 and the second connecting contact 5, so that the varistor 3 is electrically disconnected. At the same time an occurring switching arc is interrupted by the entering into the space separator 10 and thus deleted.
- an optical status display is provided, which can be recognized by a viewing window 21 formed in the upper side 20 of the housing 2.
- the optical state display is formed in the illustrated embodiment in that the release carriage 12 has a flexible colored display surface 22 which covers a formed on the inner housing 23 of the overvoltage protection element 1 differently colored area 24 in the second, upper position of the release carriage 12.

Die bekannten Überspannungsschutzelemente sind in der Regel als "Schutzstecker" ausgebildet, die zusammen mit einem Geräteunterteil ein Überspannungsschutzgerät bilden. Zur Installation eines derartigen Überspannungsschutzgeräts, welches beispielsweise die phasenführenden Leiter L1, L2, L3 sowie den Neutralleiter N und gegebenenfalls auch den Erdleiter PE schützen soll, sind bei den bekannten Überspannungsschutzgeräten am Geräteunterteil entsprechende Anschlussklemmen für die einzelnen Leiter vorgesehen. Zur einfachen mechanischen und elektrischen Kontaktierung des Geräteunterteils mit dem jeweiligen Überspannungsschutzelement sind bei dem Überspannungsschutzelement die Anschlusskontakte als Steckerstifte ausgebildet, zu denen im Geräteunterteil korrespondierende, mit den Anschlussklemmen verbundene Steckerbuchsen angeordnet sind, so dass das Überspannungsschutzelement einfach auf das Geräteunterteil aufsteckbar ist.The known overvoltage protection elements are generally designed as a "protective plug", which together with a device lower part form an overvoltage protection device. To install such a surge protection device, which is intended to protect, for example, the phase-leading conductors L1, L2, L3 and the neutral conductor N and possibly also the earth conductor PE, corresponding terminals for the individual conductors are provided in the known surge protection devices on the device base. For simple mechanical and electrical contacting of the device lower part with the respective overvoltage protection element, the connection contacts are designed as plug pins to the overvoltage protection element, which are arranged in the lower part of the device corresponding, connected to the terminals sockets, so that the overvoltage protection element is simply plugged onto the device base.
Bei derartigen Überspannungsschutzgeräten ist die Installation und Montage durch die Steckbarkeit der Überspannungsschutzelemente sehr einfach und zeitsparend durchführbar. Zusätzlich weisen derartige Überspannungsschutzgeräte teilweise noch einen Wechselkontakt als Signalgeber zur Femmeldung des Zustands mindestens eines Überspannungsschutzelements sowie eine optische Zustandsanzeige in den einzelnen Überspannungsschutzelementen auf. Über die Zustandsanzeige wird angezeigt, ob das in dem Überspannungsschutzelement angeordnete überspannungsbegrenzende Bauelement noch funktionstüchtig ist oder nicht. Als überspannungsbegrenzendes Bauelement werden dabei insbesondere Varistoren verwendet, wobei jedoch je nach Einsatzzweck des Überspannungsschutzelements auch gasgefüllte Überspannungsableiter, Funkenstrecken oder Dioden eingesetzt werden können.In such overvoltage protection devices, the installation and assembly by plugging the surge protection elements is very simple and time-saving feasible. In addition, such overvoltage protection devices partially still have a changeover contact as a signal transmitter for Femmeldung the state of at least one overvoltage protection element and an optical status display in the individual overvoltage protection elements. The status display indicates whether the overvoltage-limiting component arranged in the overvoltage protection element is still functional or not. In particular, varistors are used as overvoltage limiting component, although it is also possible to use gas-filled surge arresters, spark gaps or diodes depending on the intended use of the overvoltage protection element.
Die zuvor beschriebenen, bei den bekannten Überspannungsschutzelementen verwendeten, thermischen Abtrennvorrichtungen, die auf dem Aufschmelzen einer Lötverbindung beruhen, haben mehrere Aufgaben zu erfüllen. Im Normalzustand des Überspannungsschutzelements, d. h. im nicht getrennten Zustand, muss eine sichere und gute elektrische Verbindung zwischen dem ersten Anschlusselement und dem überspannungsbegrenzenden Bauelement gewährleistet sein. Beim Überschreiten einer bestimmten Grenztemperatur muss die Trennstelle eine sichere Abtrennung des überspannungsbegrenzenden Bauelements sowie eine dauerhafte Isolationsfestigkeit und Kriechstromfestigkeit gewährleisten. Sollen die Überspannungsschutzelements darüber hinaus möglichst kleine Abmessungen aufweisen, damit die Überspannungsschutzgeräte die für Tragschienengeräte vorgegebenen Abmessungen nicht überschreiten, so führt dies dazu, dass die bekannten Überspannungsschutzgeräte nur in den unteren und mittleren Leistungsklassen, d. h. für Impulsströme ≤ 65 kA, eingesetzt werden können.The above-described, used in the known overvoltage protection elements, thermal separation devices, which are based on the melting of a solder joint, have to fulfill several tasks. In the normal state of the overvoltage protection element, d. H. in the non-separated state, a secure and good electrical connection between the first connection element and the overvoltage limiting component must be ensured. When a certain limit temperature is exceeded, the separation point must ensure a safe separation of the overvoltage limiting component as well as a permanent insulation resistance and tracking resistance. Should the overvoltage protection element moreover have the smallest possible dimensions, so that the overvoltage protection devices do not exceed the dimensions specified for DIN rail devices, this leads to the known overvoltage protection devices only in the lower and middle power classes, ie. H. for pulse currents ≤ 65 kA, can be used.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein eingangs beschriebenes Überspannungsschutzelement zur Verfügung zu stellen, bei welchem die zuvor genannten Nachteile vermieden werden. Dabei soll sowohl eine sichere und gute elektrische Verbindung im Normalzustand als auch eine sichere Abtrennung eines defekten überspannungsbegrenzenden Bauelements gewährleistet sein. Darüber hinaus soll eine möglichst hohe Isolations- und Kriechstromfestigkeit auch bei möglichst kleiner Baugröße des Überspannungsschutzelements erzielt werden, damit das Überspannungsschutzelement möglichst hohe Impulsströme ableiten kann.The present invention is therefore based on the object to provide an initially described overvoltage protection element, in which the aforementioned disadvantages are avoided. It should be ensured both a safe and good electrical connection in the normal state and a safe separation of a defective overvoltage limiting device. In addition, the highest possible insulation and creepage current resistance even with the smallest possible size of the overvoltage protection element be achieved so that the overvoltage protection element can derive the highest possible pulse currents.
Diese Aufgabe ist bei dem eingangs beschriebenen Überspannungsschutzelement gemäß dem Patentanspruch 1 dadurch gelöst, dass das elektrisch leitfähige Verbindungselement derart mit einem isolierendem Trennelement verbunden ist, dass bei aufgetrennter thermischer Verbindung das isolierendem Trennelement zwischen den zweiten Anschlusskontakt und den zweiten Pol des überspannungsbegrenzenden Bauelements bewegt wird. Dadurch, dass das elektrisch leitfähige Verbindungselement, dass im Normalzustand des Überspannungsschutzelements zwischen dem zweiten Anschlusskontakt und dem zweiten Pol des überspannungsbegrenzenden Bauelements angeordnet und mit beiden elektrisch leitend verbunden ist, mit einem isolierenden Trennelement verbunden ist, dass bei aufgetrennter thermischer Verbindung zwischen dem zweiten Anschlusskontakt und dem zweiten Pol des überspannungsbegrenzenden Bauelements angeordnet ist, wird ein beim Öffnen der Trennstelle eventuell entstehender Lichtbogen zuverlässig durch das in die Trennstelle einfahrende isolierende Trennelement gelöscht. Im Fehlerfall des Überspannungsschutzelements, wird somit nach dem Auftrennen der Lötverbindung das leitfähige Verbindungselement durch die Kraft des Federsystems aus dem Zwischenraum zwischen dem zweiten Anschlusskontakt und dem zweiten Pol des überspannungsbegrenzenden Bauelements heraus bewegt und das isolierende Trennelement in den Zwischenraum hinein bewegt.This object is achieved in the above-described overvoltage protection element according to claim 1, characterized in that the electrically conductive connection element is connected to an insulating separator such that when disconnected thermal connection, the insulating separator between the second terminal contact and the second pole of the overvoltage limiting device is moved. Characterized in that the electrically conductive connecting element, which is arranged in the normal state of the overvoltage protection element between the second terminal contact and the second pole of the overvoltage limiting component and electrically connected to both, is connected to an insulating separating element that with a disconnected thermal connection between the second terminal contact and is arranged on the second pole of the overvoltage limiting component, a possibly resulting when opening the separation point arc is reliably deleted by the retracting into the separation point insulating separator. In the event of a fault of the overvoltage protection element, the conductive connecting element is thus moved out of the gap between the second terminal contact and the second pole of the overvoltage limiting component after the separation of the solder joint and moves the insulating separator into the gap.
Grundsätzlich gibt es verschiedene Möglichkeiten, wie das elektrisch leitfähige Verbindungselement und das isolierende Trennelement ausgebildet und miteinander verbunden sein können. Das isolierende Trennelement kann beispielsweise von einer aus isolierendem Material bestehenden Leiterplatte gebildet sein, die einen Bereich aufweist, in dem die Oberfläche der Leiterplatte auf beiden Seiten leitfähig ist, wobei die leitfähigen Oberflächen mittels Durchkontaktierungen elektrisch miteinander verbunden sind. Das Trennelement kann jedoch auch aus einem leitfähigen Material bestehen, das außer im Bereich des Verbindungselements isoliert ist, beispielsweise einen isolierenden Überzug oder eine isolierende Abdeckung aufweist.In principle, there are various ways in which the electrically conductive connecting element and the insulating separating element can be formed and connected to one another. The insulating separator may be formed, for example, by an insulating material circuit board having a region in which the surface of the circuit board is conductive on both sides, the conductive surfaces being electrically connected to each other by vias. However, the separator may also be made of a conductive material which is insulated except in the region of the connecting element, for example comprising an insulating coating or an insulating cover.
Gemäß einer bevorzugten Ausgestaltung der Erfindung werden das isolierende Trennelement von einer starren Isolierstoffplatte und das leitfähige Verbindungselement von mindestens einem Metallstück gebildet, wobei das Metallstück vorzugsweise in einer in der Isolierstoffplatte ausgebildeten Öffnung eingepresst ist. Das isolierende Trennelement und das leitfähige Verbindungselement sind dann fest miteinander verbunden, und bilden ein gemeinsames Bauteil, wodurch zum einen die Montage des Überspannungsschutzelements vereinfacht wird, zum anderen gewährleistet ist, dass sich das leitfähige Verbindungselement und das isolierende Trennelement stets gemeinsam verschieben.According to a preferred embodiment of the invention, the insulating separating element are formed by a rigid insulating plate and the conductive connecting element of at least one metal piece, wherein the metal piece is preferably pressed in a formed in the insulating plate opening. The insulating separating element and the conductive connecting element are then firmly connected to each other, and form a common component, whereby on the one hand the assembly of the overvoltage protection element is simplified, on the other hand it is ensured that the conductive connecting element and the insulating separating element always move together.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der zweite Anschlusskontakt fest mit einem starren metallischen Anschlusselement verbunden, wobei dann im Normalzustand des Überspannungsschutzelements das dem zweiten Anschlusskontakt abgewandte Ende des starren metallischen Anschlusselements über eine thermisch auftrennende Verbindung, d. h. über eine Lötverbindung, mit der einen Seite des leitfähigen Verbindungselements verbunden ist. Das starre metallische Anschlusselement kann dabei so dimensioniert sein, dass es problemlos auch Impulsströme mit sehr hohen Amplituden übertragen kann. Im Normalzustand des Überspannungsschutzelements ist dann der zweite Pol des überspannungsbegrenzenden Bauelements bzw. eine mit dem Pol verbundene Anschlusslasche mit der einen Seite des Verbindungselements und das starre metallische Anschlusselement mit der anderen Seite des Verbindungselements verlötet, so dass der zweite Anschlusskontakt über das metallische Anschlusselement und das Verbindungselement mit dem zweiten Pol des überspannungsbegrenzenden Bauelements bzw. der Anschlusslasche des zweiten Pols elektrisch leitend verbunden ist.According to a further advantageous embodiment of the invention, the second terminal contact is fixedly connected to a rigid metallic connection element, in which case in the normal state of the overvoltage protection element, the end of the rigid metallic terminal element facing away from the second terminal contact via a thermally disconnecting compound, d. H. via a solder connection to which one side of the conductive connection element is connected. The rigid metallic connecting element can be dimensioned so that it can easily transmit pulse currents with very high amplitudes. In the normal state of the overvoltage protection element, the second pole of the overvoltage limiting component or a connection lug connected to the pole is then soldered to one side of the connection element and the rigid metallic connection element is soldered to the other side of the connection element, so that the second connection contact via the metallic connection element and the Connecting element is electrically conductively connected to the second pole of the overvoltage limiting component or the terminal strap of the second pole.
Einleitend ist ausgeführt, dass bei aufgetrennter thermischer Verbindung, d. h. bei aufgetrennter Lötverbindung, das Verbindungselement durch die Kraft des Federsystems aus der Kontaktstellung bewegt wird. Grundsätzlich kann dies dadurch realisiert werden, dass eine Feder direkt zwischen dem Verbindungselement und dem Gehäuse angeordnet ist, so dass das Verbindungselement beim Auftrennen der Lötverbindung unmittelbar durch die Feder aus der Kontaktstellung herausgezogen oder herausgedrückt wird. Dabei ist es natürlich auch möglich, dass die Feder nicht an dem Verbindungselement sondern an dem - mit dem Verbindungselement fest verbundenen - isolierenden Trennelement angreift.In the introduction, it is stated that when the thermal connection is interrupted, ie when the soldered connection is interrupted, the connecting element is moved out of the contact position by the force of the spring system. In principle, this can be realized in that a spring is arranged directly between the connecting element and the housing, so that the connecting element is directly pulled out or pushed out of the contact position during separation of the solder connection by the spring. Of course, it is also possible that the spring is not on the connecting element but on the - with the connecting element firmly connected - insulating separating element attacks.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist innerhalb des Gehäuses ein Auslöseschlitten beweglich angeordnet, an dem das Federsystem derart angreift, dass bei aufgetrennter thermischer Verbindung der Auslöseschlitten durch die Kraft des Federsystems aus einer ersten Position in eine zweite Position bewegt wird. Der Auslöseschlitten ist darüber hinaus noch derart mit dem isolierenden Trennelement oder dem Verbindungselement verbunden, dass in der ersten Position des Auslöseschlittens das elektrisch leitfähige Verbindungselement und in der zweiten Position des Auslöseschlittens das isolierende Trennelement zwischen dem zweiten Anschlusskontakt und dem zweiten Pol des überspannungsbegrenzenden Bauelements bzw. der Anschlusslasche angeordnet ist. Der Auslöseschlitten dient somit dazu, das elektrisch leitfähige Verbindungselement aus dem Zwischenraum zwischen dem zweiten Anschlusskontakt bzw. dem mit dem zweiten Anschlusskontakt verbundenen starren metallischen Anschlusselement und dem zweiten Pol bzw. der mit dem zweiten Pol verbundenen Anschlusslasche herauszubewegen. Da das leitfähige Verbindungselement fest mit dem isolierenden Trennelement verbunden ist, wird dabei gleichzeitig das Trennelement in den Zwischenraum bewegt.According to a preferred embodiment of the invention, a release carriage is movably disposed within the housing, on which the spring system engages such that when separated thermal connection of the release carriage is moved by the force of the spring system from a first position to a second position. In addition, the release slide is connected to the insulating separating element or connecting element such that in the first position of the triggering slide the electrically conductive connecting element and in the second position of the triggering slide the insulating separating element between the second connecting contact and the second pole of the overvoltage limiting component or the connection tab is arranged. The release carriage thus serves to move the electrically conductive connection element out of the intermediate space between the second connection contact or the rigid metal connection element connected to the second connection contact and the second pole or the connection lug connected to the second pole. Since the conductive connecting element is firmly connected to the insulating separating element, the separating element is simultaneously moved into the intermediate space.
Je nach Ausgestaltung des Auslöseschlittens und je nachdem, ob der Auslöseschlitten an dem Verbindungselement oder an dem Trennelement angreift, wird dabei das leitfähige Verbindungselement aus dem Zwischenraum herausgeschoben oder herausgezogen. Gemäß einer bevorzugten Ausführungsvariante ist an dem Auslöseschlitten mindestens ein Mitnahmehaken angeordnet, der einen Abschnitt des isolierenden Trennelements aufnimmt. Das isolierende Trennelement wird somit, vorzugsweise an seiner Unterkante, von dem Mitnahmehaken aufgenommen, so dass das isolierende Trennelement - und damit auch das leitfähige Verbindungselement - bei der Bewegung des Auslöseschlittens aus der ersten Position in die zweite Position nach oben bewegt wird, so dass das Verbindungselement aus dem Zwischenraum heraus geschoben und das isolierende Trennelement in den Zwischenraum hinein geschoben wird.Depending on the design of the release carriage and depending on whether the release carriage engages the connecting element or on the separating element, while the conductive connecting element is pushed out of the gap or pulled out. According to a preferred embodiment, at least one driving hook is arranged on the release carriage, which receives a portion of the insulating separating element. The insulating separating element is thus, preferably at its lower edge, received by the driving hook, so that the insulating separating element - and thus the conductive connecting element - is moved during the movement of the trigger slide from the first position to the second position upwards, so that the Pushed connecting element out of the intermediate space and the insulating separating element is pushed into the intermediate space.
Bei dem erfindungsgemäßen Überspannungsschutzelement ist somit das Verbindungselement das einzige Stromführende Element, das beweglich angeordnet ist. Das metallische Anschlusselement ist dagegen ebenso wie der Anschlusskontakt starr ausgebildet, so dass beide Elemente entsprechend robust und mit entsprechend großem Querschnitt ausgebildet sein können, um auch große Impulsströme sicher übertragen zu können. Dadurch, dass keine bewegliche Leitungszuführung vorgesehen ist, kann eine sehr hohe Stoß- und Kurzschlussstromtragfähigkeit gewährleistet werden.In the case of the overvoltage protection element according to the invention, the connecting element is thus the only current-carrying element which is movably arranged. On the other hand, the metallic connection element, like the connection contact, is rigid, so that both elements can be designed to be correspondingly robust and with a correspondingly large cross section in order to be able to transmit even large pulse currents safely. The fact that no movable line feed is provided, a very high surge and short-circuit current carrying capacity can be ensured.
Das erfindungsgemäße Überspannungsschutzelement ist vorteilhafterweise als "Schutzstecker" ausgebildet, so dass es zusammen mit einem korrespondierenden Geräteunterteil ein Überspannungsschutzgerät bildet. Vorteilhafterweise weist dabei das Geräteunterteil einen Fernmeldekontakt zur Fernmeldung des Zustands des Überspannungsschutzelements auf. Zur Betätigung eines zu dem Fernmeldekontakt gehörenden Schalters im Geräteunterteil ist im Überspannungsschutzelement ein Auslösestift vorgesehen, der durch eine Öffnung in der Unterseite des Gehäuses herausragt. Vorzugsweise ist dabei der Auslösestift mit dem Auslöseschlitten verbunden, so dass durch die Bewegung des Auslöseschlittens aus der ersten Position in die zweite Position gleichzeitig der Auslösestift verschoben, d. h. angehoben wird. Hierzu ist in dem Auslöseschlitten eine köcherartige Bohrung ausgebildet, in der der Auslösestift angeordnet ist.The overvoltage protection element according to the invention is advantageously designed as a "protective plug" so that it forms an overvoltage protection device together with a corresponding device lower part. Advantageously, while the lower device part has a telecommunications contact for remote notification of the state of the overvoltage protection element. To actuate a belonging to the telecommunications contact switch in the device base a trigger pin is provided in the overvoltage protection element, which protrudes through an opening in the bottom of the housing. Preferably, the release pin is connected to the release carriage, so that moved simultaneously by the movement of the release carriage from the first position to the second position, the release pin, d. H. is raised. For this purpose, a quiver-like bore is formed in the release carriage, in which the release pin is arranged.
Gemäß einer weiteren bevorzugten Ausgestaltung dient dabei der Auslösestift gleichzeitig zur Befestigung bzw. Führung zweier Schraubenfedern, die zusammen mit dem Auslösestift das Federsystem bilden. Die beiden Schraubenfedern sind dabei auf dem Auslösestift angeordnet, der in seinem mittleren Bereich einen Flansch aufweist, so dass die eine Schraubenfeder einerseits am Gehäuse und andererseits am Flansch des Auslösestifts und die andere Schraubenfeder einerseits am Flansch und andererseits am Auslöseschlitten angreift. Bezüglich der Vorteile eines derartigen, zwei Schraubenfedern aufweisenden, Fehlersystems wird auf die
Gemäß einer letzten vorteilhaften Ausgestaltung des erfindungsgemäßen Überspannungsschutzelements, die hier noch kurz beschrieben werden soll, ist eine optische Zustandsanzeige vorgesehen, die anzeigt, ob das in dem Überspannungsschutzelement angeordnete überspannungsbegrenzende Bauelement noch funktionstüchtig ist oder nicht. Hierzu ist an dem Auslöseschlitten vorzugsweise eine farbige Anzeigefläche ausgebildet, wobei in Abhängigkeit von der Position des Auslöseschlittens die Anzeigefläche oder ein bestimmter Bereich der Anzeigefläche unterhalb eines im Gehäuse ausgebildeten Sichtfensters angeordnet ist. Das Sichtfenster kann dabei vorzugsweise in der Oberseite des Gehäuses ausgebildet sein, so dass die Zustandsanzeige auch dann einfach ablesbar ist, wenn das Überspannungsschutzgerät auf einer Tragschiene aufgerastet ist.According to a last advantageous embodiment of the overvoltage protection element according to the invention, which will be briefly described here, is an optical status indicator is provided which indicates whether the overvoltage-limiting component arranged in the overvoltage protection element is still functional or not. For this purpose, a colored display surface is preferably formed on the release carriage, wherein the display surface or a certain area of the display surface is arranged below a viewing window formed in the housing depending on the position of the release carriage. The viewing window can preferably be formed in the top of the housing, so that the status display is easy to read even when the overvoltage protection device is snapped onto a mounting rail.
Im Einzelnen gibt es nun eine Vielzahl von Möglichkeiten, das erfindungsgemäße Überspannungsschutzelement auszugestalten und weiterzubilden. Dazu wird verwiesen sowohl auf die dem Patentanspruch 1 nachgeordneten Patentansprüche als auf die nachfolgende Beschreibung eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung.

Die Figuren zeigen ein Überspannungsschutzelement 1 mit einem Gehäuse 2, wobei in dem Gehäuse 2 ein überspannungsbegrenzendes Bauelement 3 angeordnet ist. Bei den dargestellten Ausführungsbeispielen ist das überspannungsbegrenzende Bauelement ein Varistor 3; alternativ dazu kann beispielsweise auch ein Doppelvaristor oder ein gasgefüllter Überspannungsableiter als überspannungsbegrenzende Bauelement 3 verwendet werden. Das als Schutzstecker ausgebildete Überspannungsschutzelement 1 weist zwei als Messerkontakte ausgebildete Anschlusskontakte 4, 5 auf, die in korrespondierende Steckerbuchsen eines hier nicht dargestellten Geräteunterteils aufsteckbar sind.The figures show an overvoltage protection element 1 with a

Erfindungsgemäß ist das elektrisch leitfähige Verbindungselement 6 fest mit einem isolierenden Trennelement 10 verbunden, wobei in dem dargestellten Ausführungsbeispiel das Verbindungselement 6 von einem Metallstück und das isolierende Trennelement 10 von einer starren Isolierstoffplatte gebildet wird, die eine Öffnung aufweist, in der das Metallstück eingepresst ist. Aus
Im Normalzustand des Überspannungsschutzelements ist das Verbindungselement 6 einerseits mit der Anschlusslasche 9 des zweiten Pols des Varistors 3 und andererseits mit dem dem zweiten Anschlusskontakt 5 abgewandten Ende des starren Anschlusselements 11 verlötet, so dass der zweite Anschlusskontakt 5 bei bestehenden Lötverbindungen über das Anschlusselement 11, das Verbindungselement 6 und die Anschlusslasche 9 mit dem zweiten Pol des Varistors 3 verbunden ist. Aufgrund der robusten Auslegung dieser stromführenden mechanischen Teile können - wie bereits ausgeführt - auch große Impulsströme sicher übertragen und damit abgeleitet werden. Kommt es aufgrund eines Fehlerfalls des Varistors 3 zu einem Aufschmelzen der Lötverbindungen zwischen dem Verbindungselement 6 und der Anschlusslasche 9 sowie zwischen dem Verbindungselement 6 und dem Anschlusselement 11, so wird das Verbindungselement 6 durch die Kraft des Federsystems 7 aus der Kontaktstellung nach oben geschoben und gleichzeitig das isolierende Trennelement 10 in den Zwischenraum zwischen der Anschlusslasche 9 und dem starren Anschlusselement 11 eingeschoben wird. Ein beim Öffnen der Trennstelle entstehender Lichtbogen wird somit direkt durch das in die Trennstelle einfahrende isolierende Trennelement 10 gelöscht, so dass eine hohe Isolations- und Kriechstromfestigkeit und ein schnelles Löschen eines Lichtbogens gewährleistet werden kann, ohne dass der Abstand zwischen der Anschlusslasche 9 des zweiten Pols und dem zugehörigen Anschlusskontakt 5 bzw. dem Anschlusselement 11 vergrößert werden muss. Das Überspannungsschutzelement 1 kann somit relativ geringe Abmaße aufweisen, so dass es sich besonders als Steckerteil bei einem auf eine Tragschiene aufgerasteten Geräteunterteil eignet. Da nicht das Anschlusselement 11 sondern nur das Verbindungselement 6 bewegt wird, kann das als Anschlusswinkel ausgebildete Anschlusselement 11 entsprechend robust und mit einem ausreichend großen Querschnitt ausgebildet sein.In the normal state of the overvoltage protection element, the connecting

Der Auslösestift 15 weist in seinem mittleren Bereich einen umlaufenden Flansch 18 auf, an dessen Stirnseite jeweils eine auf dem Auslösestift 15 aufgesteckte Schraubenfeder 19 anliegt. Im montierten Zustand sind dabei die beiden Schraubenfedern 19 gespannt, so dass die untere Schraubenfeder 19 einerseits am Gehäuse 2 und andererseits an der unteren Stirnseite des Flansches 18 und die obere Schraubenfeder 19 einerseits an der oberen Stirnseite des Flansches 18 und andererseits an der als Köcher fungierenden einseitig geschlossenen Bohrung 14 im Auslöseschlitten 12 angreift. Die Federkräfte der Schraubenfedern 19 wirken dabei über den Auslöseschlitten 12 und dessen Mitnahmehaken 13 auf das isolierende Trennelement 10 und damit auf die Lötstellen zwischen dem Verbindungselement 6 und der Anschlusslasche 9 einerseits und dem Verbindungselement 6 und dem Anschlusselement 11 andererseits.The
Wenn nun im Laufe der Zeit durch Überlastung oder Alterung dauerhaft ein Leckstrom über den Varistor 3 fließt, führt dies zu einer Erwärmung des Varistors 3, was bei Erreichen der Schmelztemperatur des Lotes zu einem Auftrennen der Lötverbindungen führt, da die Lötstellen die erforderliche Gegenkraft zur Federkraft der beiden Schraubenfedern 19 nicht mehr aufbringen können. Dies führt dann dazu, dass der Aufnahmeschlitten 12 aus seiner ersten, unteren Position (
Zur Anzeige des Zustands des Varistors 3 bzw. des Überspannungsschutzelements 1 ist eine optische Zustandsanzeige vorgesehen, die durch ein in der Oberseite 20 des Gehäuses 2 ausgebildetes Sichtfenster 21 erkennbar ist. Die optische Zustandsanzeige wird bei dem dargestellten Ausführungsbeispiel dadurch gebildet, dass der Auslöseschlitten 12 eine flexible farbige Anzeigefläche 22 aufweist, die in der zweiten, oberen Position des Auslöseschlittens 12 einen am Innengehäuse 23 des Überspannungsschutzelements 1 ausgebildeten andersfarbigen Bereich 24 überdeckt. Der Bereich 24 des Innengehäuses 23, der sich unterhalb des Sichtfensters 21 befindet, ist beispielsweise grün eingefärbt, so dass dieser grüne Bereich 24 in der ersten, unteren Position des Auslöseschlittens 12 (
Als Alternative zur zuvor beschriebenen Ausgestaltung der optischen Zustandsanzeige, kann auch die Anzeigefläche 22 zweifarbig - grüner Bereich und roter Bereich - ausgebildet sein, wobei je nach Position des Auslöseschlittens 12 ein Bereich der Anzeigefläche 22 durch das Sichtfenster 21 sichtbar ist.As an alternative to the above-described embodiment of the optical status display, the
