Description

Die Erfindung betrifft eine elektrische Anschlussklemme nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrical connection terminal according to the preamble of claim 1.

Eine derartige Anschlussklemme ist beispielsweise aus der DE 10 2012 011 794 A1 bekannt. Das Betätigungselement ist hier über ein Lagerelement drehbar in dem Anschlussklemmengehäuse gelagert. Das Betätigungselement weist einen Grundkörper und ein einstückig an dem Grundkörper angeformten Betätigungsarm auf, welcher eine geringere Dicke aufweist als der Grundkörper. Der Betätigungsarm ist in Richtung des Federelementes gebogen ausgebildet und dient dazu, einen Halteabschnitt des Federelementes aus seiner Verrastung zu lösen, wenn das Federelement von der geschlossenen Position in die geöffnete Position überführt werden soll, indem der Halteabschnitt mittels des Betätigungsarmes in Richtung des Betätigungsschenkels gebogen wird. Sobald der Halteabschnitt aus der Verrastung gelöst ist, kann das Federelement nach oben in Richtung des Betätigungselementes verschwenken, indem das Federelement mit dem Halteabschnitt und zumindest einem Teil des Betätigungsschenkels in einen an dem Betätigungselement ausgebildeten Freiraum einschwenkt, ohne eine Drehbewegung des Betätigungselementes auszulösen. Um das Federelement von der geöffneten Position wieder in die geschlossene Position zu überführen, wird das Betätigungselement derart verdreht, dass es mit seinem Grundkörper gegen den Betätigungsschenkel des Federelementes drückt, um diesen nach unten zu drücken. Die Drehbewegung des Betätigungselementes kann mittels eines Werkzeuges, insbesondere einem Schraubendreher, erfolgen, indem dieser in eine an dem Betätigungselement ausgebildete Werkzeugeinführungsöffnung eingeführt wird, wobei die Werkzeugeinführungsöffnung an dem Grundkörper des Betätigungselementes ausgebildet ist.Such a connection terminal is, for example, from DE 10 2012 011 794 A1 known. The actuating element is rotatably mounted here in the connection terminal housing via a bearing element. The actuating element has a base body and an actuating arm which is integrally formed on the base body and has a smaller thickness than the base body. The actuating arm is bent in the direction of the spring element and is used to release a holding section of the spring element from its latching position when the spring element is to be transferred from the closed position to the open position by bending the holding section in the direction of the actuating leg by means of the actuating arm . Once the Holding section is released from the latching, the spring element can pivot upwards in the direction of the actuating element by the spring element with the holding section and at least part of the actuating leg pivoting into a free space formed on the actuating element without triggering a rotary movement of the actuating element. In order to transfer the spring element from the open position back into the closed position, the actuating element is rotated in such a way that it presses with its base body against the actuating leg of the spring element in order to press it downwards. The rotary movement of the actuating element can take place by means of a tool, in particular a screwdriver, by inserting it into a tool insertion opening formed on the actuating element, the tool insertion opening being formed on the base body of the actuating element.

Nachteilig bei diesem Betätigungselement ist der relativ große benötigte Platzbedarf des Betätigungselementes aufgrund seines relativ großen Schwenkwinkels, wobei der Schwenkwinkel des Betätigungselementes durch den relativ großen Schwenkwinkel des einstückig an dem Grundkörper angeformten Betätigungsarmes bestimmt wird. Um eine Schwenkbewegung des Betätigungselementes zu ermöglichen, muss in dem Anschlussklemmengehäuse ein zusätzlicher Freiraum geschaffen werden, in welchen das Betätigungselement insbesondere mit seinem länglich ausgebildeten Betätigungsarm beim Verschwenken des Betätigungselementes eintauchen kann. Aufgrund des zusätzlichen Freiraumes ist es notwendig, die gesamte Anschlussklemme breiter auszubilden.A disadvantage of this actuating element is the relatively large space required by the actuating element due to its relatively large swivel angle, the swivel angle of the actuating element being determined by the relatively large swivel angle of the actuating arm formed integrally on the base body. In order to enable a pivoting movement of the actuating element, an additional free space must be created in the connection terminal housing, in which the actuating element, in particular with its elongated actuating arm, can dip when the actuating element is pivoted. Because of the additional free space, it is necessary to make the entire connection terminal wider.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Anschlussklemme zur Verfügung zu stellen, welche sich durch einen reduzierten Bauraumbedarf auszeichnet.The invention is therefore based on the object of providing an electrical connection terminal which is characterized by a reduced space requirement.

Die Lösung der erfindungsgemäßen Aufgabe erfolgt mit den Merkmalen des unabhängigen Anspruchs. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The object according to the invention is achieved with the features of the independent claim. Appropriate configurations and advantageous developments of the invention are specified in the subclaims.

Die Erfindung zeichnet sich dadurch aus, dass der Grundkörper und der Betätigungsarm zweiteilig ausgebildet sind, wobei der Betätigungsarm relativ zu dem Grundkörper derart schwenkbeweglich ausgebildet ist, dass ein Schwenkwinkel (beta) der Betätigungsarms (17) kleiner als ein Schwenkwinkel (alpha) des Grundkörpers (16) ist.The invention is characterized in that the base body and the actuation arm are designed in two parts, the actuation arm being designed to be pivotable relative to the base body in such a way that a pivot angle (beta) of the actuation arms (17) is smaller than a pivot angle (alpha) of the base body ( 16) is.

Es ist nunmehr vorgesehen, dass das Betätigungselement nicht mehr einteilig ausgebildet ist, sondern der Grundkörper und der Betätigungsarm des Betätigungselements sind durch die zweiteilige Ausbildung des Betätigungselements zwei separat voneinander ausgebildete Bauteile, welche innerhalb der Anschlussklemme derart zusammengefügt sind, dass eine Relativbewegung zwischen dem Betätigungsarm und dem Grundkörper ermöglicht ist. Dadurch, dass der Betätigungsarm nunmehr schwenkbeweglich an dem Grundkörper ausgebildet bzw. angeordnet ist, ist es bei einer Drehbewegung des Betätigungselements nicht mehr notwendig, dass der Betätigungsarm die gesamte Schwenkbewegung des Grundkörpers mit ausführen muss, sondern es wird ermöglicht, dass der Betätigungsarm der Schwenkbewegung des Grundkörpers nur noch über eine Teilstrecke dieser Schwenkbewegung dem Grundkörper folgt. Hierdurch kann der notwendige Schwenkwinkel des Betätigungsarmes zum Betätigen des Federelementes, insbesondere zum Lösen der Verrastung des Federelements und zum Überführen des Federelements von der geschlossenen Position in die geöffnete Position, reduziert werden. Hierdurch kann erreicht werden, dass der Schwenkwinkel des Betätigungsarmes kleiner ist als der Schwenkwinkel des Grundkörpers. Damit ist es auch nicht mehr notwendig, dass für das Betätigungselement und insbesondere den Betätigungsarm ein zusätzlicher Freiraum im Anschlussklemmengehäuse vorgesehen werden muss, um eine ausreichende Drehbewegung bzw. Verschwenkbewegung des Betätigungselements sicherstellen zu können. Aufgrund des nunmehr nicht mehr notwendigen zusätzlichen Freiraumes innerhalb des Anschlussklemmengehäuses kann die Baubreite der gesamten Anschlussklemme bei gleichbleibender Funktionalität der Anschlussklemme reduziert werden, wodurch der gesamte notwendige Bauraum für die Anschlussklemme reduziert werden kann. Der Platzbedarf des Betätigungselements innerhalb der Anschlussklemme wird hierdurch in Bezug auf die Breite der Anschlussklemme nur noch durch das Maß bzw. die Abmessungen des Grundkörpers des Betätigungselements bestimmt und ist unabhängig von dem Maß bzw. den Abmessungen des Betätigungsarmes. Zudem ist gegenüber den bisher bekannten Lösungen eine symmetrische Anordnung des Betätigungsarmes zum Federelement ermöglicht, wodurch beim Betätigen des Federelements der Betätigungsarm mittig der Breite des Federelements eine Kraft auf das Federelement, insbesondere den nach unten gebogenen Halteabschnitt des Federelements, aufbringen kann. Dadurch wird beim Betätigen des Federelements dieses, insbesondere im Bereich des Halteabschnitts, gleichmäßig belastet, um das Federelement bzw. den Halteabschnitt des Federelements aus den Hinterschnitten an der Stromschiene lösen zu können. Ein Verkanten oder Verbiegen des Federelements bzw. des Halteabschnitts des Federelements beim Betätigen mittels des Betätigungsarmes kann dadurch verhindert werden.It is now provided that the actuating element is no longer formed in one piece, but rather the base body and the actuating arm of the actuating element are two separately formed components due to the two-part design of the actuating element, which are joined together within the connecting terminal in such a way that a relative movement between the actuating arm and the base body is enabled. Because the actuating arm is now designed or arranged to be pivotable on the base body, when the actuating element is rotated, it is no longer necessary for the actuating arm to carry out the entire pivoting movement of the base body, but rather it is possible for the actuating arm to carry out the pivoting movement of the The base body only follows the base body over a section of this pivoting movement. This allows the necessary swivel angle of the Actuating arm for actuating the spring element, in particular for releasing the latching of the spring element and for transferring the spring element from the closed position to the open position, can be reduced. In this way it can be achieved that the swivel angle of the actuating arm is smaller than the swivel angle of the base body. It is therefore no longer necessary for the actuation element and in particular the actuation arm to have to be provided with additional free space in the connection terminal housing in order to be able to ensure a sufficient rotational movement or pivoting movement of the actuation element. Due to the no longer necessary additional free space within the connection terminal housing, the overall width of the entire connection terminal can be reduced while the functionality of the connection terminal remains the same, whereby the entire space required for the connection terminal can be reduced. The space requirement of the actuating element within the connecting terminal is hereby only determined by the size or the dimensions of the base body of the actuating element in relation to the width of the connecting terminal and is independent of the size or the dimensions of the actuating arm. In addition, compared to the previously known solutions, a symmetrical arrangement of the actuating arm to the spring element is made possible, whereby when the spring element is actuated, the actuating arm can apply a force to the spring element in the middle of the width of the spring element, in particular the downwardly bent holding section of the spring element. As a result, when the spring element is actuated, it is evenly loaded, in particular in the area of the holding section, in order to release the spring element or the holding section of the spring element from the undercuts on the busbar can. Canting or bending of the spring element or the holding section of the spring element when actuated by means of the actuating arm can thereby be prevented.

Der Betätigungsarm ist bevorzugt in einer in dem Grundkörper ausgebildeten Ausnehmung schwenkbeweglich gelagert. Der Betätigungsarm kann somit innerhalb des Grundkörpers aufgenommen sein, so dass eine definierte Schwenkbewegung des Betätigungsarmes ermöglicht ist. Die Ausnehmung ist vorzugsweise derart geformt, dass zumindest ein Teil des Betätigungsarmes U-förmig von dem Grundkörper umgriffen ist, so dass ein seitliches Verkippen des Betätigungsarmes während einer Schwenkbewegung sicher verhindert werden kann. Der Betätigungsarm ist dann vorzugsweise von einer Wandung der Ausnehmung und damit des Grundkörpers sowohl an seinen beiden Stirnseitenflächen als auch an seinen beiden Längsseitenflächen umgeben, so dass die Ausnehmung eine schlitzartige Öffnung in dem Grundkörper ausbildet. Der Betätigungsarm ist vorzugsweise nicht über seine gesamte Länge innerhalb der Ausnehmung aufgenommen, sondern lediglich über einen Teilbereich seiner Länge. Der andere Teilbereich des Betätigungsarmes ragt aus dem Grundkörper heraus, so dass mittels dieses Teilbereiches die Betätigung des Federelementes mittels des Betätigungsarmes ermöglicht werden kann. Die Ausnehmung kann auch derart offen ausgebildet sein, dass die Wandung der Ausnehmung nur die beiden Stirnseitenflächen des Betätigungsarmes überdeckt und die Längsseitenflächen des Betätigungsarmes frei liegen und nicht von einer Wandung der Ausnehmung bzw. des Grundkörpers überdeckt sind, so dass diese Längsseitenflächen des Betätigungsarmes selber eine Außenfläche des Betätigungselementes ausbilden. Insbesondere wenn die Ausnehmung offen und nicht in Form einer schlitzförmigen Öffnung ausgebildet ist, kann es bevorzugt vorgesehen sein, dass in der Ausnehmung ein Steg ausgebildet ist, wobei der Betätigungsarm den Steg U-förmig umgreifen kann. Durch den Steg und das U-förmige Umgreifen des Betätigungsarmes des Steges kann ein sicherer Halt des Betätigungsarmes innerhalb der offen ausgebildeten Ausnehmung des Grundkörpers erreicht werden, da eine Verkippbewegung des Betätigungsarmes durch den Steg verhindert werden kann. Der Betätigungsarm weist bei dieser Ausgestaltung vorzugsweise eine Ausnehmung auf, in welche der Steg eingreifen kann und durch welche der Betätigungsarm den Steg U-förmig umgreifen kann. Der Betätigungsarm kann dadurch auf den Steg innerhalb der Ausnehmung des Grundkörpers aufgeschoben sein.The actuating arm is preferably mounted such that it can pivot in a recess formed in the base body. The actuating arm can thus be accommodated within the base body, so that a defined pivoting movement of the actuating arm is made possible. The recess is preferably shaped in such a way that at least part of the actuating arm is encompassed by the base body in a U-shape, so that lateral tilting of the actuating arm during a pivoting movement can be reliably prevented. The actuating arm is then preferably surrounded by a wall of the recess and thus of the base body, both on its two end faces and on its two longitudinal side surfaces, so that the recess forms a slot-like opening in the base body. The actuating arm is preferably not received within the recess over its entire length, but only over a partial area of its length. The other sub-area of the actuating arm protrudes from the base body, so that the actuation of the spring element by means of the actuating arm can be made possible by means of this sub-area. The recess can also be designed to be open in such a way that the wall of the recess only covers the two end faces of the actuating arm and the longitudinal side faces of the actuating arm are exposed and are not covered by a wall of the recess or the base body, so that these longitudinal side faces of the actuating arm themselves have a Form the outer surface of the actuating element. In particular if the recess is open and not in the form of a slot-shaped opening, it can preferably be provided that a web is formed in the recess, the actuating arm being able to encompass the web in a U-shape. The web and the U-shaped encompassing the actuating arm of the web enable the actuating arm to be held securely within the open recess of the base body, since the web can prevent the actuating arm from tilting. In this embodiment, the actuating arm preferably has a recess into which the web can engage and through which the actuating arm can engage around the web in a U-shape. The actuating arm can thereby be pushed onto the web within the recess of the base body.

Um die Schwenkbewegung des Betätigungsarmes innerhalb des Grundkörpers begrenzen zu können und zudem eine Druckkraft von dem Betätigungsarm auf das Federelement ausüben zu können, ist es bevorzugt vorgesehen, dass an dem Grundkörper mindestens ein Anschlag ausgebildet ist. Liegt der Betätigungsarm an diesem Anschlag an, so wird der Betätigungsarm zusammen mit dem Grundkörper verschwenkt, wodurch insbesondere eine Betätigung des Federelementes und insbesondere eine Kraftausübung von dem Betätigungsarm auf das Federelement realisiert werden kann. Der Anschlag ist vorzugsweise innerhalb der Ausnehmung in dem Grundkörper ausgebildet. Beispielsweise kann der Anschlag durch eine Wandung der Ausnehmung ausgebildet sein oder aber es kann auch eine zusätzliche Rippe in der Ausnehmung ausgebildet sein. Vorzugsweise ist ein zweiter Anschlag ausgebildet, welcher gegenüberliegend zu dem ersten Anschlag angeordnet ist, so dass der Betätigungsarm zwischen den beiden Anschlägen verschwenkt werden kann. Hierdurch kann die Schwenkbewegung des Betätigungsarmes zwischen zwei definierten Positionen erfolgen und der Schwenkwinkel des Betätigungsarmes kann auf ein definiertes Maximalmaß begrenzt werden. Beispielsweise kann ein erster Anschlag als Druckkante ausgebildet sein und ein zweiter Anschlag kann als eine Haltekante ausgebildet sein.In order to be able to limit the pivoting movement of the actuating arm within the base body and also to be able to exert a compressive force from the actuating arm on the spring element, it is preferably provided that at least one stop is formed on the base body. If the actuating arm rests against this stop, the actuating arm is pivoted together with the base body, whereby in particular an actuation of the spring element and, in particular, a force exerted by the actuating arm on the spring element can be implemented. The stop is preferably formed within the recess in the base body. For example, the stop can be formed by a wall of the recess or an additional rib can also be formed in the recess. A second stop is preferably formed, which is arranged opposite the first stop is so that the actuating arm can be pivoted between the two stops. As a result, the pivoting movement of the actuating arm can take place between two defined positions and the pivoting angle of the actuating arm can be limited to a defined maximum dimension. For example, a first stop can be designed as a pressure edge and a second stop can be designed as a retaining edge.

Weiter kann es vorgesehen sein, dass an dem Grundkörper und/oder an dem Betätigungsarm ein Arretierungsmittel zum Arretieren des Betätigungsarmes in einer Position relativ zu dem Grundkörper angeordnet ist. Mittels des Arretierungsmittels kann eine Verschwenkbewegung des Betätigungsarmes relativ zu dem Grundkörper verhindert werden, da mittels des Arretierungsmittels eine Fixierung des Betätigungsarmes an dem Grundkörper ermöglicht werden kann. Eine derartige Fixierung kann beispielsweise zu Montagezwecken oder aber während bestimmter Schaltlagen, beispielsweise beim Betätigen des Federelementes mittels des Betätigungsarmes, dienen. Das Arretierungsmittel kann beispielsweise in Form von Rastmitteln ausgebildet sein, indem beispielsweise an dem Grundkörper Öffnungen und an dem Betätigungsarm Rastzapfen ausgebildet sein können, wobei die Rastzapfen in die Ausnehmungen der Öffnungen eingreifen können, um den Betätigungsarm in einer definierten Position an dem Grundkörper fixieren zu können. Alternativ ist es auch möglich, dass beispielsweise die Öffnungen an dem Betätigungsarm und die Rastzapfen an dem Grundkörper ausgebildet sind. Andere Ausgestaltungen von Rastmitteln bzw. Arretierungsmitteln anstelle von Öffnungen und Rastzapfen sind ebenfalls möglich.It can further be provided that a locking means for locking the operating arm in a position relative to the base body is arranged on the base body and / or on the actuating arm. A pivoting movement of the actuating arm relative to the base body can be prevented by means of the locking means, since the actuating arm can be fixed to the base body by means of the locking means. Such a fixation can be used, for example, for assembly purposes or during certain switching positions, for example when the spring element is actuated by means of the actuating arm. The locking means can for example be in the form of latching means, for example openings can be formed on the main body and latching pins can be formed on the actuating arm, the latching pins being able to engage in the recesses of the openings in order to be able to fix the actuating arm in a defined position on the main body . Alternatively, it is also possible that, for example, the openings are formed on the actuating arm and the locking pins are formed on the base body. Other configurations of locking means or locking means instead of openings and locking pins are also possible.

Um die Montage des Betätigungselementes erleichtern zu können, ist es bevorzugt vorgesehen, dass der Grundkörper und der Betätigungsarm an einem an dem Anschlussklemmengehäuse ausgebildeten Lagerelement schwenkbeweglich gelagert sind. Das Lagerelement kann beispielsweise in Form eines Lagerzapfens ausgebildet sein, auf welchem sowohl der Grundkörper als auch der Betätigungsarm angeordnet sind. Hierfür kann der Grundkörper eine Öffnung aufweisen, welche sich vorzugsweise bis in die Ausnehmung des Grundkörpers zur Aufnahme des Betätigungsarms hinein erstreckt. Der Betätigungsarm kann vorzugsweise ein Lagerauge aufweisen, mittels welchem der Betätigungsarm auf das Lagerelement aufgeschoben werden kann. Bei einer Montage kann somit zunächst der Betätigungsarm in den Grundkörper derart eingeführt werden, insbesondere in die Ausnehmung des Grundkörpers derart eingeführt werden, dass das Lagerauge fluchtend mit der Öffnung an dem Grundkörper angeordnet ist, um anschließend den Grundkörper zusammen mit dem Betätigungsarm auf dem Lagerelement montieren zu können, indem das Betätigungselement mit der Öffnung des Grundkörpers und dem Lagerauge des Betätigungsarmes auf das Lagerelement aufgeschoben wird. Durch eine gemeinsame Lagerstelle des Grundkörpers und des Betätigungsarmes an dem Anschlussklemmengehäuse bzw. über das Lagerelement kann zudem der notwendige Bauraum für das Betätigungselement und damit für die gesamte Anschlussklemme weiter reduziert werden.In order to be able to facilitate the assembly of the actuating element, it is preferably provided that the base body and the actuating arm are pivotably mounted on a bearing element formed on the connection terminal housing. The bearing element can be designed, for example, in the form of a bearing journal on which both the base body and the actuating arm are arranged. For this purpose, the base body can have an opening which preferably extends into the recess of the base body for receiving the actuating arm. The actuating arm can preferably have a bearing eye, by means of which the actuating arm can be pushed onto the bearing element. During assembly, the actuating arm can thus first be inserted into the base body, in particular inserted into the recess of the base body, in such a way that the bearing eye is aligned with the opening on the base body, in order to then mount the base body together with the actuation arm on the bearing element by pushing the actuating element with the opening of the base body and the bearing eye of the actuating arm onto the bearing element. Through a common bearing point of the base body and the actuating arm on the connection terminal housing or via the bearing element, the installation space required for the actuation element and thus for the entire connection terminal can also be further reduced.

Ferner ist es vorzugsweise vorgesehen, dass das Anschlussklemmengehäuse zwei Leitereinführungsöffnungen aufweist und in dem Gehäuse zwei Federelemente und zwei Betätigungselemente angeordnet sind, wobei die beiden Betätigungselemente entgegengesetzt 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 platzsparend aufgeteilt sein, wodurch die gesamte elektrische Anschlussklemme besonders kompakt ausgebildet werden kann.Furthermore, it is preferably provided that the connection terminal housing has two conductor entry openings and two spring elements and two actuating elements are arranged in the housing, the two Actuating elements are rotatable opposite to one another and are opposite one another in such a way that the actuating arms of the actuating elements are arranged one behind the other in the dividing direction. Due to this special arrangement with several actuating elements in one housing of a connection terminal, the necessary installation space can be divided as space-saving as possible when two conductor connections are provided, whereby the entire electrical connection terminal can be made particularly compact.

Fig. 1 zeigt eine elektrische Anschlussklemme 100 in einer Detaildarstellung. Die elektrische Anschlussklemme 100 weist eine in einem Anschlussklemmengehäuse 10 ausgebildete Leitereinführungsöffnung 11 auf, über welche ein hier nicht gezeigter Leiter in die Anschlussklemme 100 eingeführt werden kann, um den Leiter innerhalb der Anschlussklemme 100 elektrisch leitend klemmen bzw. anschließen zu können. Fig. 1 shows an electrical connection terminal 100 in a detailed representation. The electrical connection terminal 100 has a conductor entry opening 11 formed in a connection terminal housing 10, via which a conductor, not shown here, can be inserted into the connection terminal 100 in order to be able to clamp or connect the conductor within the connection terminal 100 in an electrically conductive manner.

Zum elektrisch leitenden Klemmen bzw. Anschließen des eingeführten Leiters ist innerhalb des Anschlussklemmengehäuses 10 eine Stromschiene 12 angeordnet, welche bei der hier gezeigten Ausgestaltung U-förmig ausgebildet ist.For the electrically conductive clamping or connection of the inserted conductor, a busbar 12 is arranged within the connection terminal housing 10, which is U-shaped in the embodiment shown here.

Ferner ist in dem Anschlussklemmengehäuse 10 ein Federelement 13 drehbar gelagert angeordnet, indem das Federelement 13 auf einem Drehzapfen 14 positioniert ist. Durch die drehbare Lagerung des Federelementes 13 kann dieses in eine geöffnete Position und eine geschlossene Position verschwenkt werden, wobei in der geschlossenen Position ein in die Leitereinführungsöffnung 11 eingeführter Leiter mittels des Federelements 13 gegen die Stromschiene 11 geklemmt werden kann. Eine geschlossene Position des Federelements 13 ist beispielsweise in Fig. 2 gezeigt. Fig. 1 zeigt das Federelement 13 hingegen in einer geöffneten Position.Furthermore, a spring element 13 is rotatably mounted in the connection terminal housing 10, in that the spring element 13 is positioned on a pivot pin 14. Due to the rotatable mounting of the spring element 13, it can be pivoted into an open position and a closed position, wherein in the closed position a conductor inserted into the conductor insertion opening 11 can be clamped against the busbar 11 by means of the spring element 13. A closed position of the spring element 13 is shown in, for example Fig. 2 shown. Fig. 1 shows the spring element 13, however, in an open position.

Ferner ist in dem Anschlussklemmengehäuse 100 ein Betätigungselement 15 drehbar gelagert, mittels welchem das Federelement 13 zur Überführung in die geöffnete und in die geschlossene Position betätigt werden kann. Das Betätigungselement 15 weist einen Grundkörper 16 und einen Betätigungsarm 17 auf. Der Betätigungsarm 17 und der Grundkörper 16 sind als zwei separate Bauteile ausgebildet, so dass das Betätigungselement 15 zweiteilig ausgebildet ist. Durch die zweiteilige Ausbildung des Betätigungselementes 15 ist es möglich, dass der Betätigungsarm 17 relativ zu dem Grundkörper 16 schwenkbeweglich ausgebildet ist. An dem Grundkörper 16 ist eine Werkzeugeinführungsöffnung 18 ausgebildet, in welche ein Werkzeug, beispielsweise ein Schraubendreher, eingeführt werden kann, um das Betätigungselement 15 zu betätigen, insbesondere zu drehen bzw. zu verschwenken. Mittels des Betätigungsarmes 17 erfolgt die Betätigung des Federelementes 13, um dieses von der geschlossenen Position in die geöffnete Position zu überführen.Furthermore, an actuating element 15 is rotatably mounted in the connection terminal housing 100, by means of which the spring element 13 can be actuated for transferring into the open and closed positions. The actuation element 15 has a base body 16 and an actuation arm 17. The actuating arm 17 and the base body 16 are designed as two separate components, so that the actuating element 15 is designed in two parts. The two-part design of the actuating element 15 makes it possible for the actuating arm 17 to be designed to be pivotable relative to the base body 16. A tool insertion opening 18 is formed on the base body 16, into which a tool, for example a screwdriver, can be introduced in order to actuate the actuating element 15, in particular to rotate or pivot it. The actuation arm 17 is used to actuate the spring element 13 in order to transfer it from the closed position to the open position.

Fig. 2 zeigt das Federelement 13 in der geschlossenen Position. Zur Überführung des Federelementes 13 von der in Fig. 1 gezeigten geöffneten Position in die in Fig. 2 gezeigte geschlossene Position erfolgt eine Drehbewegung des Betätigungselementes 15 gegen den Uhrzeigersinn. Bei dieser Drehbewegung gegen den Uhrzeigersinn drückt eine an dem Außenumfang des Grundkörpers 16 ausgebildete Kante 19 auf das Federelement 13, insbesondere auf eine Oberseite 20 des Federelementes 13, so dass das Federelement 13 mittels der Kante 19 nach unten in Richtung der Stromschiene 12 gedrückt wird, um einen in die Anschlussklemme 100 eingeführten Leiter gegen die Stromschiene 12 zu drücken. Bei der Drehbewegung des Betätigungselementes 15 entgegen des Uhrzeigersinns wird der Grundkörper 16 gegen den Uhrzeigersinn verdreht und auch der Betätigungsarm 17 wird zumindest über eine Teilstrecke der Drehbewegung des Grundkörpers 16 mit diesem zusammen entgegen des Uhrzeigersinns gedreht. Die Drehbewegung bzw. Verschwenkbewegung des Betätigungsarmes 17 erfolgt damit nicht über den gesamten Schwenkwinkel des Grundkörpers 16, sondern nur über einen Teilbereich, so dass zusätzlich zu der gesamten Schwenkbewegung des Betätigungselements 15 eine Schwenkbewegung innerhalb des Betätigungselements 15 ausgeführt wird, indem der Betätigungsarm 17 relativ zu dem Grundkörper 16 verschwenkt wird, so dass der Betätigungsarm 17 in einer Endposition, wie sie in Fig. 2 gezeigt ist, im Gegensatz zu der in Fig. 1 gezeigten Position relativ zu dem Grundkörper 16 nach unten verschwenkt ist. In dieser verschwenkten Endposition ist eine Längsseitenkante 21 des Betätigungsarmes 17 parallel zu einer vertikal ausgebildeten Wand 22 des Anschlussklemmengehäuses 10 angeordnet. Würde keine Verschwenkbewegung des Betätigungsarmes 17 relativ zu dem Grundkörper 16 möglich sein, beispielsweise wenn der Betätigungsarm 17 einstückig mit dem Grundkörper 16 ausgebildet ist, würde in der in Fig. 2 gezeigten Endposition die Längsseitenkante 21 des Betätigungsarmes 17 nicht parallel zu der Wand 22 des Anschlussklemmengehäuses 10 angeordnet sein, sondern in einem im Wesentlichen rechten Winkel zu der Wand 22 positioniert sein, so dass die Wand 22, um die Verschwenkbewegung des Betätigungselements 15 nicht zu behindern, weiter entfernt von dem Betätigungselement 15 nach rechts verschoben ausgebildet sein müsste, wodurch das gesamte Anschlussklemmengehäuse 10 breiter ausgebildet sein müsste und damit mehr Bauraum benötigen würde. Fig. 2 shows the spring element 13 in the closed position. To transfer the spring element 13 from the in Fig. 1 open position shown in Fig. 2 In the closed position shown, the actuating element 15 rotates in a counterclockwise direction. During this counterclockwise rotational movement, an edge 19 formed on the outer circumference of the base body 16 presses on the spring element 13, in particular on an upper side 20 of the spring element 13, so that the spring element 13 is pressed downward in the direction of the busbar 12 by means of the edge 19, in order to press a conductor inserted into the connection terminal 100 against the busbar 12. When the actuating element 15 rotates counterclockwise, the base body 16 is rotated counterclockwise and the actuating arm 17 is also rotated counterclockwise together with the base body 16 over at least part of the rotational movement of the latter. The rotary movement or pivoting movement of the actuating arm 17 thus does not take place over the entire pivoting angle of the base body 16, but only over a partial area, so that in addition to the entire pivoting movement of the actuating element 15, a pivoting movement is carried out within the actuating element 15 by the actuating arm 17 relative to the base body 16 is pivoted so that the actuating arm 17 is in an end position, as shown in FIG Fig. 2 is shown, in contrast to that in Fig. 1 position shown relative to the base body 16 is pivoted downward. In this pivoted end position, a longitudinal side edge 21 of the actuating arm 17 is arranged parallel to a vertically formed wall 22 of the connection terminal housing 10. If no pivoting movement of the actuating arm 17 relative to the base body 16 were possible, for example if the actuating arm 17 is formed in one piece with the base body 16, in the in Fig. 2 end position shown, the longitudinal side edge 21 of the actuating arm 17 should not be arranged parallel to the wall 22 of the connection terminal housing 10, but rather be positioned at a substantially right angle to the wall 22, so that the wall 22, in order not to hinder the pivoting movement of the actuating element 15, would have to be designed shifted to the right further away from the actuating element 15, as a result of which the entire connection terminal housing 10 would have to be made wider and thus would require more installation space.

Fig. 3 zeigt eine Schnittdarstellung der in Fig. 2 gezeigten Anschlussklemme 100 mit dem Betätigungselement 15 in der in Fig. 2 gezeigten Endposition. In Fig. 3 ist der Schwenkwinkel alpha des Grundkörpers 16 und der Schwenkwinkel beta des Betätigungsarmes 17 bei einer Drehbewegung des Betätigungselementes 15 von der geöffneten Position des Federelementes 13 in die geschlossene Position des Federelementes 13 gezeigt, wobei hierbei zu erkennen ist, dass der Schwenkwinkel beta des Betätigungsarmes 17 kleiner ist als der Schwenkwinkel alpha des Grundkörpers 16. Fig. 3 shows a sectional view of the in Fig. 2 terminal 100 shown with the actuating element 15 in the in Fig. 2 shown end position. In Fig. 3 the swivel angle alpha of the base body 16 and the swivel angle beta of the actuating arm 17 are shown during a rotary movement of the actuating element 15 from the open position of the spring element 13 to the closed position of the spring element 13, whereby it can be seen that the swivel angle beta of the actuating arm 17 is smaller is than the pivot angle alpha of the base body 16.

Weiter ist in der in Fig. 3 gezeigten Schnittdarstellung des Betätigungselementes 15 zu erkennen, dass in dem Grundkörper 16 die Werkzeugeinführungsöffnung 18 ausgebildet ist, welche in Form eines spitzen Winkels ausgebildet ist.Next is in the in Fig. 3 shown sectional view of the actuating element 15 to see that in the Base body 16, the tool insertion opening 18 is formed, which is formed in the form of an acute angle.

Weiter ist in dem Grundkörper 16 eine Ausnehmung 23 ausgebildet, innerhalb welcher der Betätigungsarm 17 schwenkbeweglich gelagert ist. Die Ausnehmung 23 weist einen ersten Anschlag 24 und einen zweiten Anschlag 25 zur Begrenzung der Schwenkbewegung des Betätigungsarmes 17 auf, wobei die beiden Anschläge 24, 25 durch eine Wandung der Ausnehmung 23 ausgebildet sind. Bei der in Fig. 3 gezeigten Endposition des Betätigungselements 15, wenn das Federelement 13 in der geschlossenen Position ist, liegt der Betätigungsarm 17 mit einer ersten Stirnseitenfläche 26 flächig an dem unteren, zweiten Anschlag 25 an, wobei der Anschlag 25 hier in Form einer Haltekante ausgebildet ist. Der obere, erste Anschlag 24 bildet eine Druckkante aus, wobei der Betätigungsarm 17 mit einer der ersten Stirnseitenfläche 26 gegenüberliegenden zweiten Stirnseitenfläche 27 bei einem Betätigen des Federelements 13, wie es in Fig. 4 gezeigt ist, an diesem als Druckkante ausgebildeten Anschlag 24 anliegt, um eine Kraft bzw. Druckkraft auf das Federelement 13 zum Öffnen des Federelementes 13 ausüben zu können.Furthermore, a recess 23 is formed in the base body 16, within which the actuating arm 17 is mounted such that it can pivot. The recess 23 has a first stop 24 and a second stop 25 for limiting the pivoting movement of the actuating arm 17, the two stops 24, 25 being formed by a wall of the recess 23. At the in Fig. 3 When the spring element 13 is in the closed position, the actuating arm 17 rests flat against the lower, second stop 25 with a first end face 26, the stop 25 being designed here in the form of a retaining edge. The upper, first stop 24 forms a pressure edge, the actuating arm 17 having a second end face 27 opposite the first end face 26 when the spring element 13 is actuated, as shown in FIG Fig. 4 is shown, abuts against this stop 24, which is designed as a pressure edge, in order to be able to exert a force or compressive force on the spring element 13 to open the spring element 13.

In Fig. 3 ist ferner zu erkennen, dass der Grundkörper 16 und der Betätigungsarm 17 gemeinsam an einem an dem Anschlussklemmengehäuse 10 ausgebildeten Lagerelement 28 schwenkbeweglich gelagert sind. Dieses Lagerelement 28 ist hier in Form eines Lagerzapfens ausgebildet, auf welchem sowohl der Grundkörper 16 als auch der Betätigungsarm 17 aufgeschoben und gelagert sind. Der Grundkörper 16 weist hierfür eine Öffnung 29 im Bereich der Ausnehmung 23 auf, wie beispielsweise in Fig. 5 und 6 zu erkennen ist und der Betätigungsarm 17 weist ein Lagerauge 30 auf, wobei das Lagerauge 30 des Betätigungsarmes 17 bündig mit der Öffnung 29 angeordnet ist, um das Betätigungselement 15 und insbesondere den Grundkörper 16 und den Betätigungsarm 17 zusammen und damit zeitgleich an dem Lagerelement 28 montieren zu können.In Fig. 3 it can also be seen that the base body 16 and the actuating arm 17 are jointly mounted in a pivotable manner on a bearing element 28 formed on the connection terminal housing 10. This bearing element 28 is designed here in the form of a bearing journal on which both the base body 16 and the actuating arm 17 are pushed and supported. For this purpose, the base body 16 has an opening 29 in the region of the recess 23, such as in Figures 5 and 6 can be seen and the actuating arm 17 has a bearing eye 30, the bearing eye 30 of the actuating arm 17 being arranged flush with the opening 29 in order to assemble the actuating element 15 and in particular the base body 16 and the actuating arm 17 together and thus at the same time on the bearing element 28 to be able to.

Fig. 4 zeigt das Betätigungselement 15 beim Betätigen des Federelementes 13 zur Überführung des Federelementes 13 von der hier gezeigten geschlossenen Position in eine wie in Fig. 1 gezeigte geöffnete Position in einer Schnittdarstellung. Das Betätigungselement 15 ist hierfür im Uhrzeigersinn gedreht, so dass der Betätigungsarm 17 des Betätigungselements 15 in Kontakt mit dem Federelement 13 kommt. Dabei wird sowohl der Grundkörper 16 im Uhrzeigersinn gedreht als auch der Betätigungsarm 17, wobei jedoch die Drehbewegung bzw. Verschwenkbewegung des Betätigungsarmes 17 erst startet, wenn der Grundkörper 16 bereits über einen bestimmten Schwenkwinkel derart weit verdreht worden ist, dass der obere, erste Anschlag 24 des Grundkörpers 16 an die obere, zweite Seitenfläche 27 des Betätigungsarmes 17 anschlägt, wie in Fig. 4 gezeigt ist, um den Betätigungsarm 17 bei einer weiteren Verdrehbewegung des Betätigungselementes 15 zusammen mit dem Grundkörper 16 in Richtung des Federelements 13 zu verschwenken. Sobald der Betätigungsarm 17 mit seiner Stirnseitenfläche 27 flächig an dem oberen, ersten, als Druckkante ausgebildeten Anschlag 24 anliegt, kann bei einer weiteren Drehbewegung des Betätigungselementes 15 bzw. des Grundkörpers 16 eine Kraft, insbesondere eine Druckkraft von dem Grundkörper 16 auf den Betätigungsarm 17 und von dem Betätigungsarm 17 auf das Federelement 13 ausgeübt werden, um das Federelement 13 von der geschlossenen Position in eine wie in Fig. 1 gezeigte geöffnete Position zu überführen. Fig. 4 shows the actuating element 15 when the spring element 13 is actuated to transfer the spring element 13 from the closed position shown here into one as in FIG Fig. 1 shown open position in a sectional view. The actuating element 15 is rotated clockwise for this purpose, so that the actuating arm 17 of the actuating element 15 comes into contact with the spring element 13. Both the main body 16 and the actuating arm 17 are rotated clockwise, but the rotary movement or pivoting movement of the actuating arm 17 only starts when the main body 16 has already been rotated over a certain pivot angle to such an extent that the upper, first stop 24 of the base body 16 strikes against the upper, second side surface 27 of the actuating arm 17, as in FIG Fig. 4 is shown in order to pivot the actuating arm 17 together with the base body 16 in the direction of the spring element 13 during a further rotational movement of the actuating element 15. As soon as the actuating arm 17 with its end face 27 rests flat against the upper, first stop 24 designed as a pressure edge, a force, in particular a pressure force, can be exerted from the main body 16 on the actuating arm 17 and be exerted on the spring element 13 by the actuating arm 17 in order to move the spring element 13 from the closed position to one as in Fig. 1 to transfer shown open position.
