Description
Die Erfindung betrifft eine Anschlussklemme zum elektrischen Anschluss von Leitern, mit einem Gehäuse, mit mindestens einer in dem Gehäuse angeordneten Klemmeinrichtung zum Einklemmen eines Leiters, und mit mindestens einer mit der Klemmeinrichtung zusammenwirkenden Betätigungseinrichtung zur Betätigung der Klemmeinrichtung, wobei die Klemmeinrichtung ein Kontaktelement mit einer Kontaktfläche zur Kontaktierung eines einzuklemmenden Leiters aufweist und wobei die Klemmeinrichtung ein Übertragungselement aufweist, welches mittels der Betätigungseinrichtung betätigbar ist und mit dem Kontaktelement zusammenwirkt.The invention relates to a connection terminal for the electrical connection of conductors, comprising a housing, with at least one arranged in the housing clamping means for clamping a conductor, and having at least one cooperating with the clamping device actuator for actuating the clamping device, wherein the clamping device is a contact element with a contact surface for contacting a conductor to be clamped in and wherein the clamping device has a transmission element which can be actuated by means of the actuating device and cooperates with the contact element.
Aus der
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Anschlussklemme bereitzustellen, welche eine besonders zuverlässige Kontaktierung eines elektrischen Leiters ermöglicht.Proceeding from this, the present invention has the object to provide a terminal, which allows a particularly reliable contacting of an electrical conductor.
Diese Aufgabe wird erfindungsgemäß bei einer eingangs genannten Anschlussklemme dadurch gelöst, dass die Kontaktfläche sich in einem Kontaktbereich erstreckt, welcher auf der der Kontaktfläche abgewandten Seite eine Kraftangriffsfläche aufweist, welche mit einer Kraftübertragungsfläche des Übertragungselements zusammenwirkt, sodass in einem Schließzustand der Klemmeinrichtung das Übertragungselement mit seiner Kraftübertragungsfläche auf die Kraftangriffsfläche eine Druckkraft ausübt, wobei der Kontaktbereich die Druckkraft durch den Kontaktbereich hindurch von der Kraftangriffsfläche auf die Kontaktfläche überträgt.This object is achieved according to the invention in an aforementioned terminal in that the contact surface extends in a contact region which on the side facing away from the contact surface has a force application surface, which cooperates with a force transmission surface of the transmission element, so that in a closed state of the clamping device, the transmission element with his Power transmission surface exerts a compressive force on the force application surface, wherein the contact region transmits the pressure force through the contact region from the force application surface to the contact surface.
Bei der erfindungsgemäßen Anschlussklemme ist ein Kontaktbereich vorgesehen, welcher zum einen durch die Kontaktfläche zur Kontaktierung eines elektrischen Leiters und zum anderen durch eine Kraftangriffsfläche begrenzt ist. Das Übertragungselement weist eine Kraftangriffsfläche auf, welche eine Druckkraft auf die Kraftangriffsfläche des Kontaktbereichs ausübt, sodass die der Kraftangriffsfläche gegenüberliegende Kontaktfläche gegen einen einzuklemmenden elektrischen Leiter gedrückt wird. Die von dem Übertragungselement ausgeübte Druckkraft erstreckt sich vorzugsweise senkrecht zu der Kraftangriffsfläche und zu der Kontaktfläche, sodass eine besonders gute Kraftübertragung gewährleistet ist.In the terminal according to the invention, a contact region is provided, which is bounded on the one hand by the contact surface for contacting an electrical conductor and on the other hand by a force application surface. The transmission element has a force application surface, which exerts a compressive force on the force application surface of the contact region, so that the contact surface opposite the force application surface is pressed against an electrical conductor to be clamped. The pressure exerted by the transmission element compressive force extends preferably perpendicular to the force application surface and to the contact surface, so that a particularly good power transmission is ensured.
Eine besonders zuverlässige elektrische Kontaktierung mit einem einzuklemmenden Leiter ergibt sich, wenn ein elektrischer Kontakt der Klemmeinrichtung mit einem einzuklemmenden Leiter mittels der Kontaktfläche des Kontaktelements herstellbar ist und nicht mittels des Übertragungselements. Hierdurch ist ein lokal begrenzter Kontaktbereich definiert. Das Übertragungselement dient somit nicht zur Kontaktierung des Leiters, sondern ausschließlich zur Kraftbeaufschlagung des Kontaktbereichs.A particularly reliable electrical contact with a conductor to be clamped results when an electrical contact of the clamping device with a conductor to be clamped can be produced by means of the contact surface of the contact element and not by means of the transmission element. This defines a locally limited contact area. The transmission element thus does not serve for contacting the conductor, but exclusively for applying force to the contact region.
Bei einer Ausführungsform der Erfindung ist vorgesehen, dass das Gehäuse einen durch das Kontaktelement begrenzten Einführbereich zum Einführen eines einzuklemmenden Leiters aufweist, wobei sich der Einführbereich in Einführrichtung des Leiters gesehen verjüngt, wobei in einem Schließzustand der Klemmeinrichtung der Einführbereich im Bereich des Kontaktbereichs des Kontaktelements durch Einführung eines Leiters in Form eines Massivdrahts aufweitbar ist. Dies hat den Vorteil, dass die Betätigungseinrichtung zum Einführen eines Leiters in Form eines Massivdrahts nicht betätigt werden muss, sondern in einer Schließstellung verbleiben kann und dennoch ein Massivdraht an die Anschlussklemme angeschlossen werden kann.In one embodiment of the invention, it is provided that the housing has an insertion region delimited by the contact element for introducing a conductor to be clamped, wherein the insertion region tapers in the insertion direction of the conductor, the insertion region in the region of the contact region of the contact element passing through in a closed state of the clamping device Introduction of a conductor in the form of a solid wire is expandable. This has the advantage that the actuator for inserting a conductor in the form of a solid wire does not have to be operated, but can remain in a closed position and yet a solid wire can be connected to the terminal.
Besonders bevorzugt ist es, wenn die Aufweitung des Einführbereichs mit einer Lageveränderung und/oder Formveränderung sowohl des Kontaktelements als auch des Übertragungselements einhergeht. Hierdurch kann eine kraftschlüssige Kette aus dem anzuschließenden elektrischen Leiter, der Kontaktfläche des Kontaktbereichs, der Kraftangriffsfläche des Kontaktbereichs und der Kraftübertragungsfläche des Übertragungselements geschaffen werden.It is particularly preferred if the widening of the insertion region is accompanied by a change in position and / or a change in shape of both the contact element and the transmission element. In this way, a frictional chain of the electrical conductor to be connected, the contact surface of the contact region, the force application surface of the contact region and the Power transmission surface of the transmission element can be created.
Bei einer vorteilhaften Ausführungsform ist vorgesehen, dass das Übertragungselement federelastisch ist und vorzugsweise aus einem metallischen Material hergestellt ist. Dies ermöglicht eine besonders einfache Übertragung einer Kraft auf den Kontaktbereich des Kontaktelements.In an advantageous embodiment, it is provided that the transmission element is resilient and is preferably made of a metallic material. This allows a particularly simple transmission of a force to the contact region of the contact element.
Besonders bevorzugt ist es, wenn die Druckkraft mittels Eigenspannung des Übertragungselements erzeugt oder erzeugbar ist. Dies hat den Vorteil, dass eine Druckkraft weitestgehend unabhängig von Toleranzen der Betätigungseinrichtung bereitgestellt werden kann.It is particularly preferred if the pressure force is generated or generated by means of residual stress of the transmission element. This has the advantage that a compressive force can be provided largely independent of tolerances of the actuator.
Bevorzugt ist es ferner, wenn das Kontaktelement federelastisch ist und vorzugsweise aus einem metallischen Material hergestellt ist. Dies ermöglicht eine einfache Anpassung des Kontaktbereichs an elektrische Leiter mit unterschiedlichen Durchmessern.It is further preferred if the contact element is resilient and is preferably made of a metallic material. This allows a simple adaptation of the contact area to electrical conductors with different diameters.
Nach einer Ausführungsform der Erfindung ist vorgesehen, dass das Übertragungselement und das Kontaktelement voneinander verschiedene Bauteile sind. Auf diese Weise lässt sich eine Relativbeweglichkeit dieser Bauteile einfach realisieren.According to one embodiment of the invention, it is provided that the transmission element and the contact element are mutually different components. In this way, a relative mobility of these components can be easily realized.
Bevorzugt ist es, wenn das Übertragungselement an dem Kontaktelement gelagert ist, insbesondere schwenkbeweglich. Diese Bewegbarkeit des Kontaktelements unterstützt eine weitestgehend kraftfreie Einführung eines einzuklemmenden elektrischen Leiters, insbesondere in einer Öffnungsstellung der Betätigungseinrichtung.It is preferred if the transmission element is mounted on the contact element, in particular pivotally. This mobility of the contact element supports a largely force-free introduction of an electrical conductor to be clamped, in particular in an open position of the actuating device.
Bei einer alternativen Ausführungsform ist vorgesehen, dass das Übertragungselement und das Kontaktelement miteinander einstückig ausgebildet sind. Hierdurch kann eine besonders einfach aufgebaute und montierbare Anschlussklemme geschaffen werden, welche darüber hinaus eine besonders hohe Brandsicherheit aufweist.In an alternative embodiment it is provided that the transmission element and the contact element are formed integrally with each other. In this way, a particularly simple design and mountable terminal can be created, which also has a particularly high fire safety.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Betätigungseinrichtung einen mit dem Übertragungselement zusammenwirkenden Betätigungsabschnitt aufweist, welcher in einem von dem Kontaktelement und dem Übertragungselement begrenzten Zwischenraum angeordnet ist. Dies ermöglicht es, das Übertragungselement aktiv von dem Kontaktelement ab- oder hochzuheben, wodurch die Einführung eines Litzendrahts in den Einführbereich unterstützt wird.In a further advantageous embodiment of the invention it is provided that the actuating device has a cooperating with the transmission element actuating portion, which is arranged in a space bounded by the contact element and the transmission element intermediate space. This allows the transmission element to be actively lifted off or lifted off the contact element, thereby assisting the insertion of a litz wire into the insertion area.
Vorzugsweise weist der Betätigungsabschnitt eine Betätigungsfläche auf, welche in einer mit einem Öffnungszustand der Klemmeinrichtung korrespondierenden Öffnungsstellung der Betätigungseinrichtung mit einer Abstützfläche des Übertragungselements zusammenwirkt. Auf diese Weise kann die Klemmeinrichtung in besonders zuverlässiger Weise in einem Öffnungszustand gehalten werden, und zwar unabhängig von einem etwaigen Eigenspannungszustand des Übertragungselements.Preferably, the actuating portion has an actuating surface which cooperates with a support surface of the transmission element in an opening position of the actuating device corresponding to an opening state of the clamping device. In this way, the clamping device can be held in a particularly reliable manner in an open state, regardless of any residual stress state of the transmission element.
Bevorzugt ist es ferner, wenn der Betätigungsabschnitt eine Anlagefläche aufweist, welche in einer mit dem Schließzustand der Klemmeinrichtung korrespondierenden Schließstellung der Betätigungseinrichtung mit einer Anlagefläche des Übertragungselements zusammenwirkt. Auf diese Weise kann eine Endlage des Übertragungselements definiert werden, wodurch eine von dem Übertragungselement auf den Kontaktbereich ausgeübte Druckkraft begrenzt wird. Dies ist insbesondere vorteilhaft, wenn ein Massivdraht unter Verformung sowohl des Kontaktelements als auch des Übertragungselements in den Einführbereich der Anschlussklemme eingeführt wird.It is further preferred if the actuating portion has a contact surface which cooperates in a corresponding to the closed state of the clamping device closed position of the actuating device with a contact surface of the transmission element. In this way, an end position of the transmission element can be defined, whereby a pressure force exerted by the transmission element on the contact region is limited. This is particularly advantageous when a solid wire is introduced with deformation of both the contact element and the transmission element in the insertion of the terminal.
Ein besonders einfacher Aufbau der Anschlussklemme ergibt sich, wenn die vorstehend beschriebenen Abstützflächen und Anlagenflächen des Übertragungselements miteinander identisch sind.A particularly simple design of the terminal results when the support surfaces and bearing surfaces of the transmission element described above are identical to each other.
