Description

Die Erfindung betrifft eine elektrische Anschlussklemme mit einem eine Leitereinführungsöffnung aufweisenden Gehäuse, einer in dem Gehäuse angeordneten Stromschiene, einem in dem Gehäuse drehbar gelagerten Federelement, welches in eine geöffnete Position und in eine geschlossene Position verschwenkbar ist, wobei in der geschlossenen Position ein in die Leitereinführungsöffnung eingeführter Leiter mittels dem Federelement gegen die Stromschiene klemmbar ist, und einem in dem Gehäuse drehbar gelagerten, einen Betätigungsarm aufweisenden Betätigungselement, mittels welchem das Federelement zur Überführung in die geöffnete Position und in die geschlossene Position betätigbar ist.The invention relates to an electrical connection terminal having a housing having a conductor insertion opening, a housing arranged in the busbar, a rotatably mounted in the housing spring element which is pivotable in an open position and in a closed position, wherein in the closed position in the conductor insertion opening inserted conductor can be clamped by means of the spring element against the busbar, and a rotatably mounted in the housing, an actuating arm having actuating element, by means of which the spring element for the transfer to the open position and in the closed position is actuated.

Eine derartige elektrische Anschlussklemme ist beispielsweise aus der DE 10 2008 039 868 A1 bekannt, bei welcher ein als Schenkelfeder ausgebildetes Federelement mittels eines Betätigungselementes zur Klemmung eines in das Gehäuse eingeführten Leiters in eine geöffnete Position und eine geschlossene Position verschwenkbar ist. Um das Öffnen des Federelementes und damit das Verschwenken des Federelementes aus der geschlossenen Position in die geöffnete Position zu erleichtern, weist das Betätigungselement eine Betätigungswand und zwei seitlich neben der Betätigungswand ausgebildete Entriegelungsabschnitte auf. Bei einem Verschwenken des Federelementes aus der geschlossenen Position in die geöffnete Position kann die Betätigungswand in einen an dem Federelement ausgebildeten Schlitz eintauchen. Um das Federelement vollständig von der geschlossenen Position in die geöffnete Position zu verschwenken, muss das Betätigungselement nach oben bewegt und damit selber verschwenkt bzw. gedreht werden. Dabei gleitet die Betätigungswand des Betätigungselementes durch den Schlitz des Federelementes bis das Ende der Betätigungswand von innen an einem Schenkel des Federelementes anstößt, so das dass beim weiteren Verschwenken des Betätigungselementes auch das Federelement in die geöffnete Position verschwenkt wird.Such an electrical terminal is for example from the DE 10 2008 039 868 A1 known, in which a trained as a leg spring spring element by means of an actuating element for clamping a conductor inserted into the housing in an open position and a closed position is pivotable. In order to facilitate the opening of the spring element and thus the pivoting of the spring element from the closed position to the open position, the actuating element has an actuating wall and two unlocking sections formed laterally next to the actuating wall. Upon pivoting of the spring element from the closed position into the open position, the actuating wall can dip into a slot formed on the spring element. In order to pivot the spring element completely from the closed position to the open position, the actuating element must be moved upwards and thus itself be pivoted or rotated. In this case, the actuating wall of the actuating element slides through the slot of the spring element until the end of the actuating wall abuts on the inside of a leg of the spring element, so that during further pivoting of the actuating element and the spring element is pivoted to the open position.

Nachteilig hierbei ist, dass durch die Verschwenk- bzw. Drehbewegung des Betätigungselementes bei der Überführung des Federelementes von der geschlossenen Position in die geöffnete Position eine große Verletzungsgefahr für den Benutzer besteht, da, insbesondere bei großen Federkräften, eine große Kraft auf das Betätigungselement wirkt und damit das Betätigungselement unkontrolliert mit einer hohen Geschwindigkeit verdreht wird. Wird das Betätigungselement mit einem Werkzeug betätigt, steigt dabei zudem die Verletzungsgefahr für den Benutzer durch das schnelle, unkontrollierte Mitverschwenken des Werkzeugs.The disadvantage here is that by the pivoting or rotational movement of the actuating element in the transfer of the spring element from the closed position to the open position a great risk of injury to the user, since, especially at large spring forces, a large force acts on the actuator and so that the actuator is uncontrollably rotated at a high speed. If the actuating element is actuated with a tool, the risk of injury to the user also increases due to the rapid, uncontrolled pivoting of the tool.

DE 10 2008 039 868 offenbart die Merkmale des Oberbegriffs des unabhängigen Anspruchs 1. DE 10 2008 039 868 discloses the features of the preamble of independent claim 1.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine elektrische Anschlussklemme zur Verfügung zu stellen, bei welcher die Verletzungsgefahr für den Benutzer bei einer Überführung des Federelementes von einer geschlossenen Position in eine geöffnete Position deutlich reduziert werden kann.The invention is therefore based on the object to provide an electrical terminal available, in which the risk of injury to the user in a transfer of the spring element from a closed position to an open position can be significantly reduced.

Bei einer elektrischen Anschlussklemme der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das Betätigungselement einen an das Federelement angepassten Freiraum aufweist, in welchen das Federelement bei einer Verschwenkbewegung von der geschlossenen Position in die geöffnete Position einschwenkbar ist, ohne eine Drehbewegung des Betätigungselementes auszulösen.In an electrical terminal of the type described in more detail above, this object is achieved in that the actuating element has a spring element adapted to the free space in which the spring element in a pivoting movement from the closed position to the open position can be pivoted without triggering a rotational movement of the actuating element.

Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

Die Erfindung zeichnet sich somit dadurch aus, dass bei einer Öffnungsbewegung des Federelementes, d. h. bei einer Überführung des Federelementes von der geschlossenen Position in die geöffnete Position durch eine Verschwenkbewegung des Federelementes, keine Bewegung, insbesondere keine Drehbewegung, des Betätigungselementes erfolgt. Das Betätigungselement verbleibt somit bei einer Öffnungsbewegung des Federelementes im Wesentlichen in seiner Position. Die geöffnete Position des Federelementes ist dabei die vollständig geöffnete Position des Federelementes, in welcher sich das Federelement in einer Endlage befindet. Hierdurch wird erreicht, dass bei der Überführung des Federelementes von der geschlossenen Position in die geöffnete Position die Bewegung des Federelementes von der Bewegung des Betätigungselementes entkoppelt ist, wodurch ein sonst üblicherweise durch die Bewegung des Federelementes initiierte, unkontrollierte Bewegung des Betätigungselementes verhindert und damit die Verletzungsgefahr durch eine unerwartete Drehbewegung des Betätigungselementes für den Benutzer auf ein Minimum reduziert werden kann. Um dies zu erreichen, weist das Betätigungselement, welches in dem Gehäuse vorzugsweise oberhalb des Federelementes angeordnet ist, einen an das Federelement angepassten Freiraum, auch als Ausnehmung oder Freischnitt bezeichenbar, auf, welcher derart groß ausgebildet ist, dass das Federelement innerhalb des Freiraumes derart weit verschwenkt werden kann, dass es sich in einer Endlage in der vollständig geöffneten Position befindet, ohne dabei eine Bewegung des Betätigungselementes auszulösen. Das Federelement ist vorzugsweise als eine Schenkelfeder mit einem Klemmschenkel und einem Betätigungsschenkel ausgebildet, wobei der Betätigungsschenkel an seinem dem Klemmschenkel fernen Ende einen in Richtung des Klemmschenkels abgebogenen Halteabschnitt auf, mittels welchem das Federelement in der geschlossenen Position an einem an der Stromschiene oder dem Gehäuse ausgebildeten Halteelement verrastet. Bei einer Verschwenkbewegung des Federelementes von der geschlossenen Position in die geöffnete Position taucht insbesondere der Halteabschnitt und auch teilweise der Betätigungsschenkel des Federelementes in den Freiraum des Betätigungselementes ein. Bei einem Öffnen des Federelementes wird zunächst der Halteabschnitt des Federelementes mittels des Betätigungsarmes des Betätigungselementes aus seiner Verrastung gelöst, wobei hierbei jedoch noch keine Verschwenkbewegung des Federelementes stattfindet. Nach dem Lösen des Halteabschnittes des Federelementes aus der Verrastung durch das Betätigungselement wird das Betätigungselement trotz der Verschwenkbewegung des Federelementes, bis sich das Federelement in seiner vollständig geöffneten Position befindet, nicht mehr bewegt, insbesondere nicht gedreht. Insbesondere wenn eine große Klemmkraft beim Klemmen eines Leiters mit einem großen Leiterquerschnitt wirkt, ist es vorteilhaft, dass die Kräfte beim Lösen des Leiters und damit beim Überführen des Federelementes von der geschlossenen Position in die geöffnete Position durch die Verschwenkbewegung des Federelementes nun nicht mehr auf das Betätigungselement und damit auf das in dem Betätigungselement angeordnete Werkzeug übertragen werden, sondern gemäß der erfindungsgemäßen Lösung der Halteabschnitt des Federelementes mittels des Betätigungselementes bzw. des Betätigungsarmes des Betätigungselementes lediglich aus seiner Verrastung gelöst wird und anschließend das Federelement in die entspannte, geöffnete Position "springen" kann, d. h. verschwenkt werden kann, indem dieses in den Freiraum des Betätigungselementes eintaucht, ohne dass das Betätigungselement selber bewegt wird. Im Gegensatz zu den bekannten Anschlussklemmen ist hier bei einer Verschwenkbewegung des Federelementes zum Öffnen des Federelementes keine Bewegungskopplung zwischen dem Betätigungselement und dem Federelement gegeben. Dadurch wird ein hoher Bedienkomfort für den Benutzer bei der Verwendung der elektrischen Anschlussklemme erreicht, da hohe Rückstellkräfte des Federelementes nun nicht mehr am Betätigungselement und damit auch nicht am Werkzeug zum Betätigen des Betätigungselementes wirken, wodurch die Verletzungsgefahr für den Benutzer reduziert werden kann. Zudem wird durch die Ausbildung eines Freiraumes an dem Betätigungselement kein zusätzliches Bauteil für die Realisierung der Entkopplung zwischen dem Betätigungselement und dem Federelement benötigt.The invention is thus characterized by the fact that during an opening movement of the spring element, ie at a transfer of the spring element from the closed position to the open position by a pivoting movement of the spring element, no movement, in particular no rotational movement, of the actuating element takes place. The actuating element thus remains in an opening movement of the spring element substantially in its position. The open position of the spring element is the fully open position of the spring element, in which the spring element is in an end position. This ensures that during the transfer of the spring element from the closed position to the open position, the movement of the spring element is decoupled from the movement of the actuating element, whereby otherwise usually initiated by the movement of the spring element, uncontrolled movement of the actuating element prevents and thus the risk of injury can be reduced by an unexpected rotational movement of the actuator to the user to a minimum. In order to achieve this, the actuating element, which is preferably arranged in the housing above the spring element, has a free space adapted to the spring element, also denoted as a recess or cutout, which is designed so large that the spring element within the Free space can be pivoted so far that it is in an end position in the fully open position, without causing a movement of the actuating element. The spring element is preferably designed as a leg spring with a clamping leg and an actuating limb, wherein the actuating limb at its end remote from the clamping leg on a bent in the direction of the clamping leg holding portion, by means of which the spring element in the closed position formed on a busbar or the housing Locking element locked. In a pivoting movement of the spring element from the closed position into the open position, in particular, the holding section and also partially the actuating limb of the spring element dives into the free space of the actuating element. When the spring element is opened, the holding section of the spring element is first released from its latching by means of the actuating arm of the actuating element, although in this case no pivoting movement of the spring element takes place. After releasing the holding portion of the spring element from the latching by the actuating element, the actuating element, despite the pivoting movement of the spring element until the spring element is in its fully open position, no longer moves, in particular not rotated. In particular, when a large clamping force acts when clamping a conductor with a large conductor cross-section, it is advantageous that the forces when releasing the conductor and thus when transferring the spring element from the closed position to the open position by the pivoting movement of the spring element no longer on the Actuator and thus arranged on the in the actuator Tool are transferred, but according to the inventive solution of the holding portion of the spring element by means of the actuating element or the actuating arm of the actuating element is released only from its latching and then the spring element in the relaxed, open position "jump" can, ie can be pivoted by this immersed in the free space of the actuating element without the actuating element itself being moved. In contrast to the known connection terminals no movement coupling between the actuating element and the spring element is given here at a pivoting movement of the spring element for opening the spring element. As a result, a high level of operating comfort for the user when using the electrical terminal is achieved because high restoring forces of the spring element no longer act on the actuator and thus not on the tool for actuating the actuator, whereby the risk of injury to the user can be reduced. In addition, no additional component for the realization of the decoupling between the actuating element and the spring element is required by the formation of a free space on the actuating element.

Nach einer bevorzugten Ausgestaltung der Erfindung weist das Federelement mindestens einen Rückstellfederabschnitt auf, mittels welchem das Federelement selbsttätig von der geschlossenen Position in die geöffnete Position überführbar ist. Der Rückstellfederabschnitt bewirkt, dass, sobald der Halteabschnitt des Federelementes in der geschlossenen Position aus der Verrastung gelöst ist, das Federelement ohne zusätzliche Hilfe bzw. Hilfsmittel in die geöffnete Position verschwenkt. Der Rückstellfederabschnitt ist dafür in der geschlossenen Position des Federelementes gespannt, indem der Rückstellfederabschnitt gegen ein Element, vorzugsweise eine Platte, welche beispielsweise Teil der Stromschiene ist, gedrückt wird. Bei der Überführung des Federelementes in die geschlossene Position und in die geöffnete Position wird der Rückstellfederabschnitt auf der Platte bewegt, insbesondere verschoben. An dem Gehäuse kann dafür ein Führungselement ausgebildet sein, welches in den Rückstellfederabschnitt eingreift und diesen auf der Platte führt. Durch den Rückstellfederabschnitt ist auch eine Überführung des Federelementes von der geschlossenen Position in die geöffnete Position ohne einen angeschlossenen bzw. geklemmten Leiter möglich. Der Rückstellfederabschnitt ist vorzugsweise in Form eines Federarmes ausgebildet, welcher sich zwischen dem Betätigungsschenkel und dem Klemmschenkel erstreckt und vorzugsweise an den Betätigungsschenkel angebunden ist. Das Federelement kann einen Rückstellfederabschnitt oder aber auch zwei oder mehr Rückstellfederabschnitte aufweisen, welche vorzugsweise parallel, mit einem bestimmten Abstand zueinander angeordnet sind.According to a preferred embodiment of the invention, the spring element has at least one return spring section, by means of which the spring element can be automatically transferred from the closed position to the open position. The return spring portion causes, as soon as the holding portion of the spring element is released in the closed position from the latch, the spring element pivots without additional help or aids in the open position. The return spring section is biased in the closed position of the spring element by the return spring portion against an element, preferably a plate, which is for example part of the bus bar, is pressed. When transferring the spring element in the closed position and in the open position of the return spring portion is moved on the plate, in particular shifted. On the housing may be formed for a guide element which engages in the return spring section and this leads to the plate. By the return spring portion also a transfer of the spring element from the closed position to the open position without a connected or clamped conductor is possible. The return spring portion is preferably in the form of a spring arm which extends between the actuating leg and the clamping leg and is preferably connected to the actuating arm. The spring element may have a return spring section or else two or more return spring sections, which are preferably arranged parallel to one another at a specific distance from one another.

Eine weiter bevorzugte Ausgestaltung der Erfindung sieht vor, dass das Federelement als ein zwei oder mehr Federn aufweisendes Federpaket ausgebildet ist, wobei die Federn unterschiedlich weit in die Leitereinführungsöffnung hineinragen. Die Federn des Federpaketes liegen unmittelbar aneinander an, so dass durch den Einsatz eines Federpaketes aus zwei oder mehr Federn die auf den zu klemmenden Leiter aufgebrachte Federkraft bzw. Kontaktkraft erhöht werden kann, wodurch auch für große Leiterquerschnitte eine ausreichend große Kontaktkraft zur sicheren Klemmung aufgebracht werden kann. Um zudem ein direktes Stecken von Leitern mit einem kleinen Leiterquerschnitt zu ermöglichen, ragen die Federn des Federpaketes unterschiedlich weit in die Leitereinführungsöffnung hinein, indem die Länge der Klemmschenkel der einzelnen Federn des Federpaketes unterschiedlich groß ist. Bei mehr als zwei Federn ragen die Federn vorzugsweise in einer abgestuften Länge in die Leitereinführungsöffnung hinein. Leiter mit einem kleinen Leiterquerschnitt werden dann beispielsweise nur mit einer Feder bzw. einem Klemmschenkel einer Feder des Federpaketes gegen die Stromschiene gedrückt, wodurch ein direktes Stecken der Leiter ermöglicht wird. Bei Leitern mit einem großen Leiterquerschnitt werden diese hingegen mit mehreren oder allen Federn und damit mit mehreren oder allen Klemmschenkeln des Federpaketes gegen die Stromschiene gedrückt. Hierdurch ist die elektrische Anschlussklemme für Leiter mit unterschiedlichen Leiterquerschnitten geeignet. Soll die elektrische Anschlussklemme jedoch nur für Leiter mit einem bestimmten Leiterquerschnitt verwendet werden, ist es auch möglich, dass die Federn des Federpaketes gleich weit in die Leitereinführungsöffnung hineinragen, um eine besonders hohe Kontaktkraft auf den zu klemmenden Leiter aufbringen zu können.A further preferred embodiment of the invention provides that the spring element is designed as a two or more springs having spring package, wherein the springs protrude differently far into the conductor insertion opening. The springs of the spring assembly are directly adjacent to each other, so that by applying a spring assembly of two or more springs on the force applied to the clamped spring force or contact force can be increased, which also for large conductor cross sections a sufficiently large contact force for secure clamping can be applied. In addition, to allow a direct plugging of conductors with a small conductor cross-section, the springs of the spring package protrude differently far into the conductor insertion opening, by the length of the clamping legs of the individual springs of the spring assembly is of different sizes. With more than two springs, the springs preferably protrude in a stepped length into the conductor insertion opening. Ladder with a small conductor cross-section are then pressed, for example, only with a spring or a clamping leg of a spring of the spring assembly against the busbar, whereby a direct insertion of the conductor is made possible. For conductors with a large conductor cross-section, however, they are pressed against the busbar with several or all springs and thus with several or all clamping legs of the spring assembly. This makes the electrical connection terminal suitable for conductors with different conductor cross-sections. However, if the electrical connection terminal is to be used only for conductors with a specific conductor cross section, it is also possible for the springs of the spring assembly to protrude equally far into the conductor insertion opening in order to be able to apply a particularly high contact force to the conductor to be clamped.

Um zu verhindern, dass insbesondere in einer geschlossenen Position des Federelementes, wenn ein Leiter mittels des Federelementes gegen die Stromschiene geklemmt wird, das Betätigungselement frei bewegbar ist, ist es bevorzugt vorgesehen, dass das Betätigungselement ein Rastmittel zum Halten des Betätigungselementes in einer festen Position aufweist. Das Rastmittel kann beispielsweise in Form eines an dem Betätigungselement ausgebildeten Pins oder Steges ausgebildet sein, welcher seitlich von dem Betätigungselement absteht und beispielsweise an einem an der Innenseite des Gehäuses ausgebildeten Halteelement, beispielsweise ausgebildet in Form eines Steges oder einer Rippe, hinterhaken kann.In order to prevent that, in particular in a closed position of the spring element, when a conductor is clamped by the spring element against the busbar, the actuating element is freely movable, it is preferably provided that the actuating element has a locking means for holding the actuating element in a fixed position , The locking means may be formed, for example in the form of a pin formed on the actuating element or web, which laterally from the Actuator projecting and, for example, on a formed on the inside of the housing holding element, for example, formed in the form of a web or a rib, can hook behind.

Um große Kräfte übertragen zu können, ist es weiter bevorzugt vorgesehen, dass das Betätigungselement eine Werkzeugeinführöffnung zum Betätigen des Betätigungselementes mittels eine Werkzeuges aufweist. Die Drehbewegung des Betätigungselementes kann somit mittels eines Werkzeuges, beispielsweise eines Schraubendrehers, bewirkt werden.In order to transfer large forces, it is further preferred that the actuating element has a tool insertion opening for actuating the actuating element by means of a tool. The rotational movement of the actuating element can thus be effected by means of a tool, for example a screwdriver.

Das Betätigungselement ist vorzugsweise derart ausgebildet, dass dieses einen Grundkörper aufweist, an welchem der Betätigungsarm ausgebildet ist, wobei der Grundkörper eine größere Dicke aufweist als der Betätigungsarm. Durch die größere Dicke des Grundkörpers kann dieser eine besonders große Stabilität aufweisen, so dass über den Grundkörper des Betätigungselementes große Kräfte aufgenommen werden können. An dem Grundkörper ist vorzugsweise eine Durchgangsöffnung ausgebildet, über welche das Betätigungselement an einem Lagerzapfen des Gehäuses drehbar gelagert ist.The actuating element is preferably designed such that it has a base body on which the actuating arm is formed, wherein the base body has a greater thickness than the actuating arm. Due to the greater thickness of the base body of this can have a particularly high stability, so that over the main body of the actuating element large forces can be absorbed. On the base body, a passage opening is preferably formed, via which the actuating element is rotatably mounted on a bearing journal of the housing.

Ferner ist es vorzugsweise vorgesehen, dass das Gehäuse zwei Leitereinführungsöffnungen aufweist und in dem Gehäuse zwei Federelemente und zwei Betätigungselemente angeordnet sind, wobei die beiden Betätigungselemente entgegensetzt zueinander drehbar sind und sich derart gegenüberliegen, dass die Betätigungsarme der Betätigungselemente in Teilungsrichtung hintereinander angeordnet sind. Durch diese spezielle Anordnung bei mehreren Betätigungselementen in einem Gehäuse einer Anschlussklemme kann der notwendige Bauraum bei einem Vorsehen von zwei Leiteranschlüssen möglichst Platz sparend aufgeteilt sind, wodurch die gesamte elektrische Anschlussklemme besonders kompakt ausgebildet werden kann.Further, it is preferably provided that the housing has two conductor insertion openings and two spring elements and two actuating elements are arranged in the housing, wherein the two actuating elements are opposite to each other rotatable and opposite each other such that the actuating arms of the actuating elements are arranged in the direction of division one behind the other. Due to this special arrangement with several actuators in a housing of a terminal, the necessary space can be divided as possible to save space with a provision of two wire connections, whereby the entire electrical terminal can be made very compact.

Nachfolgend wird die Erfindung unter Bezugnahme auf die anliegenden Zeichnungen anhand einer bevorzugten Ausführungsform näher erläutert.The invention will be explained in more detail below with reference to the accompanying drawings with reference to a preferred embodiment.

Fig. 1 zeigt eine Schnittdarstellung einer elektrischen Anschlussklemme gemäß der Erfindung, welche ein Gehäuse 1 mit einer ersten Leitereinführungsöffnung 2a und einer zweiten Leitereinführungsöffnung 2b aufweist. In dem Gehäuse 1 ist eine Stromschiene 3 angeordnet, gegen welche in die Leitereinführungsöffnungen 2a, 2b eingeführte Leiter 23a, 23b, wie in Fig. 6 gezeigt ist, kontaktierend geklemmt werden können. Bei der hier gezeigten Ausführungsform erstreckt sich die Stromschiene 3 von der ersten Leitereinführungsöffnung 2a zu der zweiten Leitereinführungsöffnung 2b, so dass der in die erste Leitereinführungsöffnung 2a eingeführte Leiter 23a an dieselbe Stromschiene 3 kontaktierend geklemmt wird wie der in die zweite Leitereinführungsöffnung 2b eingeführte Leiter 23b. Bei der hier gezeigten Ausführungsform ist die Stromschiene 3 im Wesentlichen U-förmig gebogen ausgebildet, wie dies insbesondere in Fig. 3 erkennbar ist. Fig. 1 shows a sectional view of an electrical terminal according to the invention, which has a housing 1 with a first conductor insertion opening 2a and a second conductor insertion opening 2b. In the housing 1, a bus bar 3 is arranged, against which inserted into the conductor insertion openings 2a, 2b conductors 23a, 23b, as in Fig. 6 is shown, can be clamped contacting. In the embodiment shown here, the bus bar 3 extends from the first conductor insertion opening 2a to the second conductor insertion opening 2b, so that the conductor 23a inserted into the first conductor insertion opening 2a is clamped contacting the same busbar 3 as the conductor 23b inserted into the second conductor insertion opening 2b. In the embodiment shown here, the busbar 3 is formed bent substantially U-shaped, as in particular in Fig. 3 is recognizable.

Ferner ist in dem Gehäuse 1 ein erstes Federelement 4a und ein zweites Federelement 4b angeordnet, wobei das erste Federelement 4a gegenüberliegend zu dem zweiten Federelement 4b angeordnet ist. Die beiden Federelemente 4a, 4b sind jeweils an einem Lagerzapfen 5a, 5b drehbar gelagert, so dass die Federelemente 4a, 4b getrennt voneinander in eine geschlossen Position und in eine geöffnete Position überführbar sind. In Fig. 1 sind beide Federelemente 4a, 4b in einer geschlossenen Position angeordnet.Further, a first spring element 4a and a second spring element 4b is arranged in the housing 1, wherein the first spring element 4a is arranged opposite to the second spring element 4b. The two spring elements 4a, 4b are each rotatably mounted on a bearing journal 5a, 5b, so that the spring elements 4a, 4b can be separately transferred into a closed position and into an open position. In Fig. 1 Both spring elements 4a, 4b are arranged in a closed position.

Die Federelemente 4a, 4b sind hier jeweils als ein Federpaket ausgebildet, welches eine erste Feder 6a, 6b und eine zweite Feder 7a, 7b aufweist. Die zweite Feder 7a, 7b liegt dabei an der Innenfläche der ersten Feder 6a, 6b an. Beide Federn 6a, 6b, 7a, 7b sind als Schenkelfedern ausgebildet, welche einen Klemmschenkel 8a, 8b, 9a, 9b und einen Betätigungsschenkel 10a, 10b, 11a, 11b aufweisen. Mittels des Klemmschenkels 8a, 8b, 9a, 9b ist ein die Leitereinführungsöffnung 2a, 2b eingeführter Leiter 23a, 23b gegen die Stromschiene 3 klemmbar. Dabei weist der Klemmschenkel 9a, 9b der zweiten, innenliegenden Feder 7a, 7b eine größere Länge auf als der Klemmschenkel 8a, 8b der ersten, außenliegenden Feder 6a, 6b, so dass beim Klemmen von Leitern 23a, 23b mit einem kleinen Leiterquerschnitt diese nur mittels des Klemmschenkels 9a, 9b der zweiten Feder 7a, 7b gegen die Stromschiene 3 geklemmt werden und beim Klemmen von Leitern 23a, 23b mit einem großen Leiterquerschnitt diese mittels des Klemmschenkels 8a, 8b der ersten Feder 6a, 6b und des Klemmschenkels 9a, 9b der zweiten Feder 7a, 7b gegen die Stromschiene 3 geklemmt werden.The spring elements 4a, 4b are here each formed as a spring assembly, which has a first spring 6a, 6b and a second spring 7a, 7b. The second spring 7a, 7b rests against the inner surface of the first spring 6a, 6b. Both springs 6a, 6b, 7a, 7b are designed as torsion springs, which have a clamping leg 8a, 8b, 9a, 9b and an actuating leg 10a, 10b, 11a, 11b. By means of the clamping leg 8a, 8b, 9a, 9b, a conductor 23a, 23b introduced the conductor insertion opening 2a, 2b can be clamped against the busbar 3. In this case, the clamping leg 9a, 9b of the second, inner spring 7a, 7b has a greater length than the clamping leg 8a, 8b of the first, outer spring 6a, 6b, so that when clamping conductors 23a, 23b with a small conductor cross-section this only by means of the clamping leg 9a, 9b of the second spring 7a, 7b are clamped against the busbar 3 and the terminals of conductors 23a, 23b with a large conductor cross section by means of the clamping leg 8a, 8b of the first spring 6a, 6b and the clamping leg 9a, 9b of the second Spring 7a, 7b are clamped against the busbar 3.

An dem Betätigungsschenkel 10a, 10b der ersten Feder 6a, 6b, welcher länger ausgebildet ist als der Betätigungsschenkel 11a, 11b der zweiten Feder 7a, 7b, ist an seinem dem Klemmschenkel 8a, 8b fernen Ende ein in Richtung des Klemmschenkels 8a, 8b abgebogener Halteabschnitt 12a, 12b ausgebildet, mittels welchem die erste Feder 6a, 6b und damit das als Federpaket ausgebildete Federelement 4a, 4b in der geschlossenen Position an einem an der Stromschiene 3 oder dem Gehäuse 1 ausgebildeten Halteelement, hier nicht gezeigt, verrasten kann.On the actuating leg 10a, 10b of the first spring 6a, 6b, which is longer than the actuating leg 11a, 11b of the second spring 7a, 7b, at its the clamping leg 8a, 8b far end in the direction of the clamping leg 8a, 8b bent holding portion 12a, 12b formed, by means of which the first spring 6a, 6b and thus designed as a spring assembly spring element 4a, 4b in the closed position on a formed on the busbar 3 or the housing 1 holding element, not shown here, can lock.

In Fig. 5 ist ferner die zweite Feder 7a, 7b des als Federpaket ausgebildeten Federelementes 4a, 4b separat dargestellt, wobei hierbei erkennbar ist, dass die zweite Feder 7a, 7b einen Rückstellfederabschnitt 13a, 13b in Form eines Federarmes aufweist, welcher sich zwischen dem Betätigungsschenkel 11a, 11b und dem Klemmschenkel 9a, 9b erstreckt und an den Betätigungsschenkel 11a, 11b angebunden ist. Der Rückstellfederabschnitt 13a, 13b weist eine wesentlich geringere Breite auf, als der Betätigungsschenkel 11a, 11b.In Fig. 5 furthermore, the second spring 7a, 7b of the spring element 4a, 4b designed as a spring assembly is shown separately, wherein it can be seen that the second Spring 7a, 7b has a return spring portion 13a, 13b in the form of a spring arm, which extends between the actuating limb 11a, 11b and the clamping leg 9a, 9b and is connected to the actuating limbs 11a, 11b. The return spring portion 13a, 13b has a substantially smaller width than the actuating legs 11a, 11b.

In einer wie in Fig. 1 gezeigten geschlossenen Position der Federelemente 4a, 4b ist der Rückstellfederabschnitt 13a, 13b "gespannt", was bedeutet, dass der Rückstellfederabschnitt 13a, 13b zu dem Betätigungsschenkel 11a, 11b hin gebogen ist, so dass der Rückstellfederabschnitt 13a, 13b im Wesentlichen parallel zu dem Betätigungsschenkel 11a, 11b angeordnet ist. Der Rückstellfederabschnitt 13a, 13b wird dabei gegen eine Platte 14a, 14b gedrückt, welcher hier Teil der Stromschiene 3 ist.In a like in Fig. 1 As shown in the closed position of the spring elements 4a, 4b, the return spring section 13a, 13b is "tensioned", which means that the return spring section 13a, 13b is bent towards the actuating limb 11a, 11b so that the return spring section 13a, 13b is substantially parallel to the actuating limb 11a, 11b is arranged. The return spring portion 13a, 13b is pressed against a plate 14a, 14b, which is part of the busbar 3 here.

In Fig. 5 ist der Rückstellfederabschnitt 13a, 13b in einem "nicht gespannten" Zustand gezeigt, bei welchem das Federelement 4a, 4b in einer geöffneten Position angeordnet ist, wie dies auch in Fig. 2 gezeigt ist. Der Rückstellfederabschnitt 13a, 13b ist hier an einer Seitenfläche der Feder 7a, 7b angeordnet. Er kann jedoch auch entlang der Breite der Feder 7a, 7b, beispielsweise mittig, angeordnet sein. Ferner ist es auch möglich, zwei oder mehr Rückstellfederabschnitte 13, 13b an einer Feder 7a, 7b vorzusehen, wobei diese dann vorzugsweise mit einem Abstand parallel zueinander angeordnet sind, wobei beispielsweise ein erster Rückstellfederabschnitt an einer ersten Seitenfläche der Feder und ein zweiter Rückstellfederabschnitt an einer der ersten Seitenfläche gegenüberliegenden zweiten Seitenfläche der Feder angeordnet sein können, hier nicht gezeigt.In Fig. 5 the return spring portion 13a, 13b is shown in a "non-tensioned" state, in which the spring element 4a, 4b is arranged in an open position, as also in FIG Fig. 2 is shown. The return spring portion 13a, 13b is arranged here on a side surface of the spring 7a, 7b. However, it can also be arranged along the width of the spring 7a, 7b, for example centrally. Furthermore, it is also possible to provide two or more return spring portions 13, 13b on a spring 7a, 7b, which are then preferably arranged at a distance parallel to each other, for example, a first return spring portion on a first side surface of the spring and a second return spring portion on a the first side surface opposite second side surface of the spring may be arranged, not shown here.

Zum Betätigen der Federelemente 4a, 4b und damit der Federpakete sind in dem Gehäuse 1 ferner zwei als Exzenter ausgebildete Betätigungselemente 15a, 15b angeordnet. Die Betätigungselemente 15a, 15b sind über Lagerzapfen 16a, 16b drehbar in dem Gehäuse 1 gelagert. Die Betätigungselemente 15a, 15b weisen einen Grundkörper 17a, 17b und einen an dem Grundkörper 17a, 17b angeformten Betätigungsarm 18a, 18b auf, welcher eine geringere Dicke aufweist als der Grundkörper 17a, 17b, wie dies insbesondere in Fig. 3 erkennbar ist. Der Betätigungsarm 18a, 18b ist in Richtung des Federelementes 4a, 4b gebogen ausgebildet und dient dazu, den Halteabschnitt 12a, 12b des Federelementes 4a, 4b aus seiner Verrastung zu lösen, wenn das Federelement 4a, 4b von der geschlossenen Position in die geöffnete Position überführt werden soll, indem der Halteabschnitt 12a, 12b mittels des Betätigungsarmes 18a, 18b in Richtung des Betätigungsschenkels 10a, 10b, 11a, 11b gebogen wird, wie dies auf der rechten Seite der Anschlussklemme in Fig. 1 gezeigt ist. Sobald der Halteabschnitt 12a, 12b aus der Verrastung gelöst ist, kann das Federelement 4a, 4b nach oben in Richtung des Betätigungselementes 15a, 15b verschwenken, indem das Federelement 4a, 4b mit dem Halteabschnitt 12a, 12 und zumindest einem Teil des Betätigungsschenkels 10a, 10b, 11a, 11b in einen an dem Betätigungselement 15a, 15b ausgebildeten Freiraum 19a, 19b einschwenkt, ohne eine Drehbewegung des Betätigungselementes 15a, 15b auszulösen, wie dies in Fig. 2 gezeigt ist.For actuating the spring elements 4a, 4b, and thus the spring assemblies, two actuating elements 15a, 15b designed as eccentrics are furthermore arranged in the housing 1. The actuating elements 15a, 15b are rotatably mounted in the housing 1 via bearing journals 16a, 16b. The actuating elements 15a, 15b have a main body 17a, 17b and an actuating arm 18a, 18b integrally formed on the main body 17a, 17b, which has a smaller thickness than the main body 17a, 17b, as shown particularly in FIG Fig. 3 is recognizable. The actuating arm 18a, 18b is bent in the direction of the spring element 4a, 4b and serves to release the holding portion 12a, 12b of the spring element 4a, 4b from its latching when the spring element 4a, 4b is transferred from the closed position to the open position is to be bent by the holding portion 12a, 12b by means of the actuating arm 18a, 18b in the direction of the actuating leg 10a, 10b, 11a, 11b, as shown on the right side of the terminal in Fig. 1 is shown. Once the holding portion 12a, 12b is released from the latch, the spring element 4a, 4b can pivot upward in the direction of the actuating element 15a, 15b, by the spring element 4a, 4b with the holding portion 12a, 12 and at least a portion of the actuating limb 10a, 10b , 11a, 11b pivots into a free space 19a, 19b formed on the actuating element 15a, 15b, without triggering a rotational movement of the actuating element 15a, 15b, as shown in FIG Fig. 2 is shown.

Um das Federelement 4a, 4b von der geöffneten Position wieder in die geschlossene Position zu überführen, wird das Betätigungselement 15a, 15b derart verdreht, dass es, vorzugsweise mit seinem Grundkörper 17a, 17b, gegen den Betätigungsschenkel 10a, 10b, 11a, 11b des Federelementes 4a, 4b drückt um diesen nach unten zu drücken.In order to return the spring element 4a, 4b from the open position to the closed position, the actuating element 15a, 15b is rotated such that it, preferably with its base body 17a, 17b, against the actuating limb 10a, 10b, 11a, 11b of the spring element 4a, 4b pushes to push this down.

Die Drehbewegung des Betätigungselementes 15a, 15b kann mittels eines Werkzeuges, insbesondere einem Schraubenzieher erfolgen, indem dieses in eine an dem Betätigungselement 15a, 15b ausgebildete Werkzeugeinführöffnung 20a, 20b eingeführt wird, wobei die Werkzeugeinführöffnung 20a, 20b an dem Grundkörper 17a, 17b des Betätigungselementes 15a, 15b ausgebildet ist.The rotational movement of the actuating element 15a, 15b can be effected by means of a tool, in particular a screwdriver, by inserting this into a tool insertion opening 20a, 20b formed on the actuating element 15a, 15b, the tool insertion opening 20a, 20b on the main body 17a, 17b of the actuating element 15a , 15b is formed.

Um die Betätigungselemente 15a, 15b in einer festen Position zu halten, insbesondere wenn die Federelemente 4a, 4b sich in der geschlossenen Position befinden, weisen die Betätigungselemente 15a, 15b ein Rastmittel 21a, wie in Fig. 3 gezeigt ist, auf, wobei hier nur das Rastmittel 21a an dem linken Betätigungselement 15a zu erkennen ist, mittels welchen die Betätigungselemente 15a, 15b unabhängig voneinander relativ zu dem Gehäuse 1 fixiert werden können. Das Rastmittel 15a ist hier in Form eines Pins ausgebildet, welcher an dem Grundkörper 17a des Betätigungselementes 15a angeformt ist, indem dieser vertikal von der Seitenfläche des Betätigungselementes 15a absteht. Zum Halten des Betätigungselementes 15a in einer festen Position kann das Rastmittel 21a beispielsweise an einem an der Innenseite des Gehäuses 1 ausgebildeten Halteelement, beispielsweise ausgebildet in Form eines Steges oder einer Rippe, hier nicht gezeigt, hinterhaken. Vorzugsweise mittels eines Werkzeuges kann die Hinterhakung gelöst werden, so dass das Betätigungselement 15a wieder frei beweglich ist, um beispielsweise das Federelement 4a aus der Verrastung der geschlossenen Position durch Betätigen des Halteabschnittes 12a des Federelementes 4a zu lösen.In order to keep the actuating elements 15a, 15b in a fixed position, in particular when the spring elements 4a, 4b are in the closed position, the actuating elements 15a, 15b have a latching means 21a, as in FIG Fig. 3 is shown, wherein only the locking means 21a can be seen on the left actuating element 15a, by means of which the actuating elements 15a, 15b can be fixed independently relative to the housing 1 here. The locking means 15a is formed here in the form of a pin, which is integrally formed on the main body 17a of the actuating element 15a by this projecting vertically from the side surface of the actuating element 15a. For holding the actuating element 15a in a fixed position, the locking means 21a, for example, on a formed on the inside of the housing 1 holding element, for example, formed in the form of a web or a rib, not shown, behind hook. Preferably, by means of a tool, the Hinterhakung can be solved, so that the Actuator 15a is again freely movable, for example, to release the spring element 4a from the locking of the closed position by actuating the holding portion 12a of the spring element 4a.

Bei der in den Fig. 1 - 4 und 6 gezeigten Ausführungsform weist die elektrische Anschlussklemme ein Gehäuse 1 mit zwei sich gegenüberliegenden Leitereinführungsöffnungen 2a, 2b, zwei sich gegenüberliegenden Federelementen 4a, 4b und zwei sich gegenüberliegenden Betätigungselementen 15a, 15b auf.
