Die vorliegende Erfindung betrifft ein Anschlusssystem zum elektrischen Verbinden zweier Geräte mit einer Klemme, die einen Klemmenkäfig und ein Druckstück aufweist, so dass sich eine vorbestimmte Innenkontur der Klemme ergibt, und einem Leiter, der an einem vorbestimmten Leiterabschnitt durch das Druckstück in den Klemmenkäfig der Klemme einpressbar ist. Darüber hinaus betrifft die vorliegende Erfindung eine Installationsgerätekombination, insbesondere einen Leitungsschutzschalter mit einer Fehlerstromeinheit.The The present invention relates to a connection system for electrical Connecting two devices with a clamp having a clamp cage and a pressure piece, so that a predetermined inner contour of the terminal results, and a conductor, which at a predetermined conductor portion through the Pressure piece in the terminal cage the terminal is einpressbar. About that In addition, the present invention relates to an installation device combination, in particular a circuit breaker with a fault current unit.
Gemäß der europäischen Gerätevorschrift „EN 61008-1" ist eine Klemme an einem Installationsgerät derart zu gestalten, dass die dauernde Erhaltung des notwendigen Kontaktdrucks mit dem angeschlossenen Leiter sichergestellt ist. Dies bedeutet, dass sowohl die mechanische als auch die elektrische Verbindung dauerhaft gewährleistet sein muss.According to the European device regulation "EN 61008-1" is a terminal on an installation device in such a way that the lasting preservation of the necessary Contact pressure with the connected conductor is ensured. This means that both the mechanical and the electrical Permanently guaranteed connection have to be.
Reiheneinbaugeräte, die unter diese Vorschrift fallen, bestehen beispielsweise aus einem Leitungsschutzschalter und einer Fehlerstromeinheit. Die Geräte werden entweder an dem entsprechenden Aufstellungsort montiert oder bereits werkseitig für einen Kunden zu einer Einheit komplettiert.Modular devices that fall under this provision, for example, consist of one Circuit breaker and a fault current unit. The devices will be either mounted on the corresponding site or already factory for completes a customer into a single entity.
Als Leiter zur Verbindung der Installationsgeräte werden in der Regel Litzen verwendet. Auf die Enden dieser fein- bzw. feinstdrähtigen Leiter werden sogenannte Aderendhülsen gecrimpt. Schraubklemmen stellen die dauerhafte Aufrechterhaltung des notwendigen Kontaktdrucks sicher. Der Leiter wird dann durch Reibung mechanisch in seiner Position gehalten. Dies bedeutet, dass eine reibschlüssige Verbindung zwischen Leiter und Klemme vorliegt. Die Kontaktflächen sind oftmals klein, da nur hervorstehende Stege des Druckstücks mit dem Leiter bzw. der Aderendhülse in Berührung kommen.When Conductors for connecting the installation equipment are usually strands used. On the ends of these fine or feinsthähtigen ladder become so-called ferrules crimped. Screw terminals provide long-lasting maintenance the necessary contact pressure safely. The conductor is then through Friction mechanically held in position. This means that a frictional connection between the conductor and the terminal. The contact surfaces are often small, since only protruding webs of the pressure piece with the conductor or the ferrule in touch come.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, die mechanische und elektrische Verbindung zwischen Leiter und Klemme zu verbessern.The The object of the present invention is therefore the mechanical and improve electrical connection between conductor and terminal.

Es kann sich bei dem vorbestimmten Leiterabschnitt aber auch um ein Mittelstück des Leiters handeln, bei dem eine verbesserte elektrische und mechanische Kontaktierung erzielt werden soll.Preferably the predetermined conductor portion is a conductor end. It may be at the predetermined conductor portion but also around a center piece of the conductor act, in which an improved electrical and mechanical contact should be achieved.
Im Falle, dass der Leiter ein Litzenleiter ist, kann der vorbestimmte Leiterabschnitt pressgeschweißt sein. Durch dieses Verfahren lässt sich der Litzenleiter dauerhaft in die gewünschte Form bringen.in the If the conductor is a stranded conductor, the predetermined Conductor section press-welded be. By this method leaves the stranded conductor permanently bring in the desired shape.
Alternativ kann das Leiterende mit einer Aderendhülse versehen sein, die derart gepresst ist, dass sie die der Innenkontur der Klemme entsprechende Oberflächenstruktur aufweist. Durch die Verwendung der Aderendhülse lässt sich die vorliegende Erfindung mit einfachen Werkzeugen realisieren.alternative For example, the conductor end can be provided with a wire end sleeve which is such is pressed, that it corresponds to the inner contour of the terminal surface structure having. By using the ferrule, the present invention can be realize with simple tools.
Entsprechend einer bevorzugten Ausführungsform ist die Oberflächenstruktur des Leiterabschnitts durch mindestens eine im Wesentlichen senkrecht zur Längsrichtung des Leiters verlaufende Vertiefung oder Erhöhung charakterisiert. Insbesondere ist es günstig, wenn sowohl der Klemmenkäfig als auch das Druckstück jeweils mindestens einen im Wesentlichen senkrecht zur Längsrichtung des Leiters sich erstreckenden entsprechenden Vorsprung bzw. eine entsprechende Vertiefung aufweist. Durch diese Art des Formschlusses lassen sich die Auszugskräfte weiter erhöhen.Corresponding a preferred embodiment is the surface texture the conductor portion by at least one substantially perpendicular to the longitudinal direction characterized the head extending depression or increase. Especially is it cheap if both the terminal cage as also the pressure piece each at least one substantially perpendicular to the longitudinal direction the head extending corresponding projection or a having corresponding recess. Through this type of positive connection let the pull-out forces continue to increase.
