Description

Die Erfindung betrifft eine elektrische Klemme in Schneid-Anschlußtechnik, insbesondere zum Aufrasten auf eine Tragschiene, mit einem Gehäuse, mit Anschlüssen für isolierte Leiter, mit mindestens einer Stromschiene, mit mindestens zwei Betätigungselementen und mit mindestens zwei Schneidelementen, wobei die Betätigungselemente relativ zu den Schneidelementen in der elektrischen Klemme drehbar angeordnet sind und jeweils eine für die anzuschließenden Leiter vorgesehene Leiteraufnahme aufweisen und die Schneidelemente den elektrischen Kontakt eines in die Leiteraufnahme eingesteckten Leiters mit der Stromschiene herstellen.The invention relates to an electrical terminal in cutting-connection technology, in particular for snapping onto a mounting rail, with a housing, with terminals for insulated conductors, with at least one busbar, with at least two actuators and at least two cutting elements, wherein the actuating elements relative to the cutting elements are rotatably disposed in the electrical terminal and each having a provided for the conductors to be connected conductor receiving and the cutting elements make the electrical contact of an inserted into the conductor receiving conductor with the busbar.

Elektrische Klemmen, insbesondere Reihenklemmen, sind seit Jahrzehnten bekannt und werden millionenfach bei der Verdrahtung elektrischer Anlagen und Geräte verwendet. Die Klemmen werden meist auf Tragschienen aufgerastet, welche ihrerseits häufig in einer Mehrzahl in einem Schaltschrank angeordnet sind. Die Klemmen sind in der Regel als Verbindungsklemmen ausgebildet, so daß sie mindestens zwei Leiteranschlußelemente aufweisen, die über eine elektrisch leitende Verbindungsschiene, die Stromschiene, elektrisch miteinander verbunden sind. Neben diesem Grundtyp der Reihenklemmen gibt es darüber hinaus eine Vielzahl von unterschiedlichen Reihenklemmentypen, die speziell den jeweiligen Anwendungsfällen angepaßt sind. Als Beispiel seien hier Doppelstock- oder Dreistock-Klemmen sowie Dreileiter- oder Vierleiter-Klemmen genannt, die dann jeweils eine entsprechend größere Anzahl an Leiteranschlußelementen aufweisen.Electrical terminals, especially terminal blocks, have been known for decades and are used a million times in the wiring of electrical equipment. The terminals are usually snapped onto mounting rails, which in turn are often arranged in a plurality in a control cabinet. The terminals are usually designed as connection terminals, so that they have at least two conductor connection elements which are electrically connected to one another via an electrically conductive connection rail, the busbar. In addition to this basic type of terminal blocks, there are also a variety of different types of terminal blocks that are specially adapted to the particular application. As an example, two-level or three-level terminals as well as three-wire or four-wire terminals may be mentioned, which then each have a correspondingly larger number of conductor connection elements.

Als Leiteranschlußelemente werden in Reihenklemmen überwiegend Schraubklemmen oder Zugfederklemmen verwendet. Das Klemmprinzip bei Zugfederklemmen ist ähnlich dem der Schraubtechnik. Während bei der Schraubklemme eine Zughülse durch die Betätigung der Klemmenschraube den Leiter gegen den Strombalken zieht, wird bei der Zugfederklemme diese Aufgabe von der Zugfeder übernommen. Hierzu wird die vorgespannte Zugfeder mit einem Betätigungswerkzeug, beispielsweise einem Schraubendreher geöffnet, so daß der Leiter durch ein Fenster im Federschenkel der Zugfeder in den Anschlußraum eingeführt werden kann. Nach dem Entfernen des Betätigungswerkzeuges wird der Leiter durch die Federkraft der Zugfeder gegen den Strombalken gezogen.As conductor connection elements predominantly screw terminals or tension spring terminals are used in terminal blocks. The clamping principle with tension spring clamps is similar to that of screwdriving technology. While with the screw terminal a tension sleeve pulls the conductor against the current bar by the operation of the clamping screw, this task is taken over by the tension spring at the tension spring clamp. For this purpose, the prestressed tension spring is opened with an actuating tool, such as a screwdriver, so that the conductor can be inserted through a window in the spring leg of the tension spring in the terminal compartment. After removing the operating tool The conductor is pulled by the spring force of the tension spring against the current bar.

Sowohl bei der Schraubklemme als auch bei der Zugfederklemme muß der elektrische Leiter nach dem Ablängen zunächst abisoliert werden, bevor die Kontaktierung des elektrischen Leiters erfolgen kann. Da für das Abisolieren des elektrischen Leiters Spezialwerkzeuge erforderlich sind und da das Abisolieren relativ viel Zeit in Anspruch nimmt, werden seit vielen Jahren auch elektrische Klemmen verwendet, an die elektrische Leiter ohne vorheriges Abisolieren angeschlossen werden können. Dazu wird der isolierte Leiter in eine Leiteraufnahme im Gehäuse der Klemme eingeführt und anschließend in ein Schneidelement gedrückt, wodurch die Isolierung des Leiters durchtrennt und die Seele des Leiters von dem Schneidelement kontaktiert wird. Dabei gibt es eine Vielzahl von Ausführungsmöglichkeiten derartiger Klemmen zum Anschluß von nicht-abisolierten Leitern. Diese unterscheiden sich insbesondere dadurch, wie der in die Leiteraufnahme eingeführte Leiter in das Schneidelement gedrückt wird.Both in the screw and the tension spring clamp, the electrical conductor must first be stripped after cutting before the contact of the electrical conductor can take place. Since special tools are required for the stripping of the electrical conductor and since the stripping takes a relatively long time, also electrical terminals are used for many years, can be connected to the electrical conductors without prior stripping. For this purpose, the insulated conductor is inserted into a conductor receptacle in the housing of the clamp and then pressed into a cutting element, whereby the insulation of the conductor is severed and the soul of the conductor is contacted by the cutting element. There are a variety of possible embodiments of such terminals for connecting non-stripped conductors. These differ in particular in how the introduced into the conductor receiving conductor is pressed into the cutting element.

Eine eingangs beschriebene elektrische Klemme in Schneid-Anschlußtechnik ist beispielsweise aus der DE 199 21 775 A1 bekannt. Bei dieser bekannten Verbindungsklemme stützen sich die Betätigungselemente mittels relativ großer, radartiger Führungen in einer von der Gehäuseseitenwand gebildeten Drehlagerung ab. Dadurch, daß die Betätigungselemente direkt in einer Seitenwand des Gehäuses drehbar gelagert sind, steht für den anzuschließenden Leiter ein maximaler Durchmesser zur Verfügung. Somit kann bei einem gegebenen Leiterquerschnitt die Breite der elektrischen Klemme relativ klein gewählt werden. Die radartige Führung der Betätigungselemente in der Seitenwand hat jedoch den Nachteil, daß aufgrund der großen, radartigen Führungen auch die Höhe der elektrischen Klemme relativ groß ist. Außerdem kann es durch die großen, radartigen Führungen u. U. zu Problemen bei der Einhaltung der erforderlichen Kriechstrecken und damit zu Isolationsproblemen insbesondere bei höheren Strömen kommen.An electrical clamp described in the cutting connection technology described above, for example, from DE 199 21 775 A1 known. In this known connection terminal, the actuators are supported by means of relatively large, radartiger guides in a rotary bearing formed by the housing side wall. Characterized in that the actuating elements are rotatably mounted directly in a side wall of the housing, a maximum diameter is available for the conductor to be connected. Thus, with a given conductor cross-section, the width of the electrical terminal can be chosen to be relatively small. However, the wheel-like guidance of the actuators in the side wall has the disadvantage that due to the large, wheel-like guides and the height of the electrical terminal is relatively large. In addition, it can u by the large, wheel-like guides. U. lead to problems in compliance with the required creepage distances and thus to insulation problems, especially at higher currents.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine eingangs beschriebene elektrische Klemme in Schneid-Anschlußtechnik zur Verfügung zu stellen, die bei einem möglichst einfachen Aufbau eine gute und sichere Handhabung gewährleistet und darüber hinaus nach Möglichkeit eine kleine Baugröße aufweist.The present invention is therefore an object of the invention to provide an electrical terminal described in cutting-line technology available, which in a simple construction as possible, a good and safe Guaranteed handling and beyond, if possible, has a small size.

Diese Aufgabe ist bei der erfindungsgemäßen elektrischen Klemme mit den Merkmalen des Patentanspruchs 1 gelöst. Durch das Zusammenwirken der beiden Zapfen mit den beiden voneinander beabstandeten Langlöchern in der Seitenwand des Gehäuses ergibt sich nicht nur eine Lagerung des Betätigungselements beim Verschwenken, wie dies bei einem normalen Drehzapfen der Fall ist, sondern gleichzeitig auch eine Begrenzung der maximal möglichen Drehung bzw. Verkippung des Betätigungselements. Um beim Verschwenken des Betätigungselements aus der ersten Stellung in die zweite Stellung eine Drehbewegung des Betätigungselements zu ermöglichen, sind die beiden Langlöcher so angeordnet, daß sie auf einer gemeinsamen Kreisbahn liegen und voneinander beabstandet sind. Der Mittelpunkt der Kreisbahn entspricht dabei der Schwenkachse des Betätigungselements. Dadurch, daß jeweils ein Zapfen in jeweils einem der Langlöcher geführt und begrenzt ist, ergibt sich eine besonders sichere Führung des Betätigungselements bei Verschwenken aus der ersten Stellung in die zweite Stellung.This object is achieved in the electrical terminal according to the invention with the features of claim 1. The interaction of the two pins with the two spaced apart slots in the side wall of the housing not only results in a bearing of the actuating element during pivoting, as is the case with a normal pivot, but at the same time a limitation of the maximum possible rotation or tilting of the actuating element. In order to allow a pivoting movement of the actuating element during pivoting of the actuating element from the first position to the second position, the two elongated holes are arranged so that they lie on a common circular path and are spaced from each other. The center of the circular path corresponds to the pivot axis of the actuating element. The fact that in each case a pin is guided and limited in each case one of the elongated holes, results in a particularly secure guidance of the actuating element during pivoting from the first position to the second position.

Zusätzlich zu der erfindungsgemäßen Führung des Betätigungselements durch das Zusammenspiel der Zapfen mit den Langlöchern ist vorzugsweise eine Ausnehmung in den Betätigungselementen ausgebildet und sind im Inneren des Gehäuses korrespondierende Rippen angeordnet. Beim Verschwenken des Betätigungselements aus der ersten Stellung (Einführstellung) in die zweite Stellung (Kontaktstellung) greifen dann die Rippen in die Ausnehmungen in den Betätigungselementen ein. Somit wird eine zusätzliche Führung des Betätigungselements beim Verschwenken durch das Eingreifen der Rippe in die Ausnehmung erreicht. Die Führung des Betätigungselements kann dabei dadurch weiter verbessert werden, daß an der Stirnseite des Betätigungselements oberhalb der Ausnehmung ein radialer Vorsprung ausgebildet ist, der sich beim Verschwenken des Betätigungselements aus der Einführstellung in die Kontaktstellung auf der Rippe abstützt. Bei der zuvor beschriebenen bevorzugten Ausgestaltung der erfindungsgemäßen elektrischen Klemme erfolgt die Abstützung bzw. Führung des Betätigungselements somit sowohl in der Seitenwand als auch im Inneren des Gehäuses. Dadurch ist eine besonders sichere Führung des Betätigungselements gewährleistet, so daß auch hohe Beschaltungskräfte beim Kontaktieren von Leitern mit relativ großem Querschnitt beherrscht werden.In addition to the guide according to the invention of the actuating element by the interaction of the pins with the oblong holes, a recess is preferably formed in the actuating elements and are arranged in the interior of the housing corresponding ribs. When pivoting the actuating element from the first position (insertion) to the second position (contact position) then engage the ribs in the recesses in the actuators. Thus, an additional guidance of the actuating element during pivoting is achieved by the engagement of the rib in the recess. The guide of the actuating element can thereby be further improved in that a radial projection is formed on the end face of the actuating element above the recess, which is supported during pivoting of the actuating element from the insertion position into the contact position on the rib. In the preferred embodiment of the electrical clamp according to the invention described above, the support or guide of the actuating element thus takes place both in the side wall and in the interior of the housing. As a result, a particularly secure guidance of the actuating element is ensured, so that even high Beschaltungskräfte be controlled when contacting conductors with a relatively large cross-section.

Besonders vorteilhaft ist es, wenn die zuvor beschriebene Rippe im Inneren des Gehäuses so ausgebildet und angeordnet, daß die Rippe gleichzeitig auch als Zugentlastung für einen eingesteckten Leiter wirkt. Dies wird dadurch erreicht, daß in der zweiten Stellung (Kontaktstellung) des Betätigungselements ein in die Leiteraufnahme eingesteckter Leiter durch die Rippe geklemmt bzw. fixiert wird. Durch eine entsprechende Dimensionierung der Rippe kann dabei gewährleistet werden, daß bei der Klemmung des Leiters lediglich die Isolierung des Leiters und nicht dessen Seele eingedrückt wird. Durch eine derartige Klemmung des angeschlossenen elektrischen Leiters wird eine "Ruhigstellung" der Kontaktstelle des elektrischen Leiters bzw. der Seele mit dem Schneidelement gewährleistet. Hierdurch wird dem in der Praxis auftretenden Problem entgegengewirkt, daß es aufgrund von Zugbeanspruchungen an den elektrischen Leitern zu einer geringen Relativbewegung zwischen dem elektrischen Leiter und dem Schneidelement kommt, was zu Oxidation und einem hohen Übergangswiderstand führen kann.It when the previously described rib in the interior of the housing is designed and arranged so that the rib also acts as a strain relief for an inserted conductor is particularly advantageous. This is achieved in that in the second position (contact position) of the actuating element, an inserted into the conductor receiving conductor is clamped or fixed by the rib. By an appropriate dimensioning of the rib can be ensured that in the clamping of the conductor, only the insulation of the conductor and not its soul is pressed. By such a clamping of the connected electrical conductor a "immobilization" of the contact point of the electrical conductor or the soul is ensured with the cutting element. As a result, the problem occurring in practice is counteracted that it comes due to tensile stresses on the electrical conductors to a small relative movement between the electrical conductor and the cutting element, which can lead to oxidation and a high contact resistance.

Zur einfachen Handhabung der elektrischen Klemme kann das Betätigungselement gemäß einer bevorzugten Ausgestaltung der erfindungsgemäßen elektrischen Klemme sowohl in einer ersten Stellung, in der das Einstecken eines ankommenden Leiters möglich ist (Einführstellung), als auch in einer zweiten Stellung, in der der Leiter durch das Schneidelement kontaktiert ist (Kontaktstellung), verrastet werden. Hierzu sind im oberen Bereich des Betätigungselements an einer Stirnseite Rippen ausgebildet, die mit dem oberen Rand der Klemme eine Verrastung bilden Dadurch besteht die Möglichkeit, die elektrische Klemme beim Ausliefern an den Kunden in der ersten Stellung, der Einführstellung, zu fixieren, so daß beim Anschließen einzelner elektrischer Leiter an eine Vielzahl von nebeneinander auf einer Tragschiene aufgerasteten elektrischen Klemmen die jeweiligen Leiter von dem Monteur problemlos in die jeweiligen Leiteraufnahmen eingeschoben werden können. Die Möglichkeit der Verrastung in der zweiten Stellung, der Kontaktstellung, verhindert, daß ein einmal angeschlossener elektrischer Leiter - ungewollt - wieder aus der elektrischen Klemme herausgezogen werden kann.For easy handling of the electrical terminal, the actuator according to a preferred embodiment of the electrical terminal according to the invention both in a first position in which the insertion of an incoming conductor is possible (insertion), as well as in a second position in which the conductor through the cutting element is contacted (contact position), to be locked. For this purpose, ribs are formed in the upper region of the actuating element on one end face, which form a latching with the upper edge of the clamp. There is the possibility of fixing the electrical clamp when delivering it to the customer in the first position, the insertion position, so that at Connecting individual electrical conductors to a plurality of juxtaposed on a DIN rail clamped electrical terminals, the respective ladder can be easily inserted by the installer in the respective conductor receptacles. The possibility of locking in the second position, the contact position prevents a once connected electrical conductor - unintentionally - can be pulled out of the electrical terminal again.

Die gewünschte geringe Baugröße der elektrischen Klemme wird zunächst - bezüglich der Bauhöhe - durch die Ausbildung der relativ kleinen Zapfen anstelle der relativ großen, radartigen Führungen bei der aus der DE 199 21 775 A1 bekannten Klemme erreicht. Die Baubreite der erfindungsgemäßen Klemme kann zum einen dadurch reduziert werden, daß bei der besonders bevorzugten doppelten Führung der Betätigungselemente sowohl durch die Zapfen und die Langlöcher als auch durch die Rippen in Verbindung mit den Ausnehmungen, die Wandstärke der Seitenwand sehr gering gewählt werden kann. Darüber hinaus kann die Baubreite dadurch weiter verringert werden, daß die Leiteraufnahme, die vorzugsweise als Langloch ausgebildet ist, eine offene Längsseite aufweist. Dadurch kann die Breite des Betätigungselements - und damit auch die Gesamtbreite der elektrischen Klemme - verringert werden, ohne daß sich der maximale Querschnitt der anzuschließenden Leiter verringert.The desired small size of the electrical terminal is first - in terms of height - by the formation of relatively small pin instead of the relatively large, wheel-like guides in the off DE 199 21 775 A1 reached known terminal. The width of the clamp according to the invention can be reduced by the fact that in the particularly preferred double guide the actuators both by the pins and the slots and by the ribs in conjunction with the recesses, the wall thickness of the side wall can be very low. In addition, the width can be further reduced by the fact that the conductor receiving, which is preferably formed as a slot, has an open longitudinal side. Thereby, the width of the actuating element - and thus also the total width of the electrical terminal - can be reduced without reducing the maximum cross section of the conductors to be connected.

Im einzelnen gibt es nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße elektrische Klemme auszugestalten und weiterzubilden. Dazu wird verwiesen einerseits auf die dem Patentanspruch 1 nachgeordneten Patentansprüche, andererseits auf die Beschreibung eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung.

In addition, the electrical terminals 1 each have two cutting elements 5, which are each electrically connected by the busbar 3.

Die Betätigungselemente 4, die jeweils eine Leiteraufnahme 6 für die - hier nicht dargestellten - anzuschließenden Leiter aufweisen, sind relativ zu den Schneidelementen 5 drehbar in dem Gehäuse 2 der elektrischen Klemme 1 angeordnet, so daß die Betätigungselemente 4 aus einer ersten Stellung, in der das Einstecken eines ankommenden Leiters in die Leiteraufnahme 6 möglich ist (Einführstellung), in eine zweite Stellung, in der die Leiter durch die Schneidelemente 5 kontaktiert sind (Kontaktstellung), verschwenkt werden können. Bei der in Fig. 2 dargestellten elektrischen Klemme 1 befindet sich das linke Betätigungselement 4 in der Einführstellung, während sich das rechte Betätigungselement 4 in der Kontaktstellung befindet.The actuating elements 4, each having a conductor receptacle 6 for - not shown here - to be connected conductors are rotatably arranged relative to the cutting elements 5 in the housing 2 of the electrical terminal 1, so that the actuating elements 4 from a first position in which Insertion of an incoming conductor into the conductor receptacle 6 is possible (insertion position), in a second position in which the conductors are contacted by the cutting elements 5 (contact position), can be pivoted. At the in Fig. 2 illustrated electrical terminal 1 is the left actuator 4 in the insertion position, while the right actuator 4 is in the contact position.

Bei der elektrischen Klemme 1 ist nun vorgesehen, daß an einer Seitenfläche 7 des Betätigungselementes 4 zwei Zapfen 8, 9 und in der entsprechenden Seitenwand 10 des Gehäuses 2 zwei korrespondierendes Langlöcher 11, 12 angeordnet bzw. ausgebildet sind. Beim Verschwenken des Betätigungselements 4 aus der ersten Stellung, in der das Einstecken eines ankommenden Leiters möglich ist (Einführstellung), in die zweite Stellung, in der der Leiter durch das Schneidelement 5 kontaktiert ist (Kontaktstellung), wird dann das Betätigungselement 4 durch die Führung der Zapfen 8, 9 in den Langlöchern 11, 12 geführt wobei gleichzeitig die Schwenkbewegung durch die Langlöcher 11, 12 begrenzt ist. Durch die Länge der Langlöcher 11, 12 wird dabei der maximal mögliche Drehwinkel der Betätigungselemente 4 festgelegt.In the electrical terminal 1 is now provided that on a side surface 7 of the actuating element 4, two pins 8, 9 and in the corresponding side wall 10 of the housing 2, two corresponding slots 11, 12 are arranged or formed. When pivoting the actuating element 4 from the first position in which the insertion of an incoming conductor is possible (insertion), in the second position in which the conductor is contacted by the cutting element 5 (contact position), then the actuating element 4 through the guide the pin 8, 9 guided in the oblong holes 11, 12 wherein at the same time the pivoting movement is limited by the slots 11, 12. By the length of the slots 11, 12 while the maximum possible rotation angle of the actuators 4 is set.

Der Fig. 1 kann dabei entnommen werden, daß die beiden Langlöcher 11, 12 so in der Seitenwand 10 des Gehäuses 2 angeordnet sind, daß die Längsachsen der beiden Langlöcher 11, 12 näherungsweise senkrecht zueinander stehen. Hierdurch wird eine besonders gute Führung des Betätigungselements 4 in dem Gehäuse 2 der elektrischen Klemme 1 gewährleistet.Of the Fig. 1 can be seen that the two slots 11, 12 are arranged in the side wall 10 of the housing 2, that the longitudinal axes of the two slots 11, 12 are approximately perpendicular to each other. As a result, a particularly good guidance of the actuating element 4 in the housing 2 of the electrical terminal 1 is ensured.

Die Führung bzw. Lagerung des Betätigungselements 4 in dem Gehäuse 2 ist dadurch weiter verbessert, daß in dem Betätigungselement 4 eine Ausnehmung 13 ausgebildet und im Inneren des Gehäuses 2 eine korrespondierende Rippe 14 angeordnet ist, wobei die Rippe 14 beim Verschwenken des Betätigungselements aus der Einführstellung - linke Seite der in Fig. 1 dargestellten elektrischen Klemme 1 - in die Kontaktstellung - rechte Seite der in Fig. 2 dargestellten elektrischen Klemme 1 - in die Ausnehmung 13 eingreift. Den Figuren kann dabei entnommen werden, daß sowohl die Ausnehmung 13 als auch die Rippe 14 kreisbogenförmig ausgebildet sind, so daß die Schwenkbewegung des Betätigungselements 4 durch das Zusammenwirkung von Ausnehmung 13 und Rippe 14 nicht beeinträchtigt wird. Vielmehr erfährt das Betätigungselement 4 durch das Zusammenwirken von Ausnehmung 13 und Rippe 14 eine zusätzliche Führung. Diese Führung kann dadurch noch weiter verbessert werden, daß an der Stirnseite 15, an der die Ausnehmung 13 ausgebildet ist, ein radialer Vorsprung 16 in Form einer Nase ausgebildet ist, der sich beim Verschwenken des Betätigungselements 4 in die Kontaktstellung auf der Rippe 14 abstützt.The guide or storage of the actuating element 4 in the housing 2 is further improved in that in the actuating element 4, a recess 13 is formed and in the interior of the housing 2 a corresponding Ridge 14 is arranged, wherein the rib 14 during pivoting of the actuating element from the insertion position - left side of in Fig. 1 illustrated electrical terminal 1 - in the contact position - right side of in Fig. 2 illustrated electrical terminal 1 - engages in the recess 13. The figures can be seen that both the recess 13 and the rib 14 are circular arc-shaped, so that the pivotal movement of the actuating element 4 is not affected by the interaction of recess 13 and rib 14. Rather, the actuator 4 undergoes an additional guide by the interaction of recess 13 and rib 14. This guide can be further improved by the fact that on the end face 15, on which the recess 13 is formed, a radial projection 16 is formed in the form of a nose, which is supported during pivoting of the actuating element 4 in the contact position on the rib 14.

Die zuvor beschriebene Rippe 14 dient - im Zusammenspiel mit der Ausnehmung 13 - nicht nur zur Führung des Betätigungselements 4, sondern gleichzeitig auch als Zugentlastung für einen in die Leiteraufnahme 6 eingesteckten Leiter. Dies wird dadurch erreicht, daß die vordere Kante der Rippe 14 in der Kontaktstellung des Betätigungselements 4 geringfügig in die Leiteraufnahme 6 hineinragt, wodurch ein angeschlossener Leiter geklemmt wird. Durch diese Klemmung eines angeschlossenen Leiters wird eine "Ruhigstellung" der Kontaktstelle zwischen dem Schneidelement 5 und dem angeschlossenen Leiter erreicht. Wie insbesondere der Fig. 1 entnommen werden kann, sind die Rippen 14 in dem Gehäuse 2 kurz oberhalb der Schneidelemente 5 angeordnet. Somit wird die gewünschte Zugentlastung möglichst nahe an der Kontaktstelle des eingesteckten Leiters mit dem Schneidelement 5 realisiert.The rib 14 described above serves - in conjunction with the recess 13 - not only to guide the actuating element 4, but at the same time as a strain relief for an inserted into the conductor receiving 6 conductor. This is achieved in that the front edge of the rib 14 slightly protrudes in the contact position of the actuating element 4 in the conductor receiving 6, whereby a connected conductor is clamped. By means of this clamping of a connected conductor, an "immobilization" of the contact point between the cutting element 5 and the connected conductor is achieved. How the particular Fig. 1 can be removed, the ribs 14 are arranged in the housing 2 just above the cutting elements 5. Thus, the desired strain relief is realized as close to the contact point of the inserted conductor with the cutting element 5.

An einer Stirnseite des Betätigungselements 4 sind im oberen Bereich Rippen 17 ausgebildet, die zusammen mit dem oberen Rand des Gehäuses 2 eine zweistufige Verrastung bilden. Dadurch kann das Betätigungselement 4 sowohl in der Einführstellung als auch in der Kontaktstellung fixiert werden, so daß zum einen die Möglichkeit besteht, die elektrische Klemme 1 beim Ausliefern an Kunden in der Einführstellung zu fixieren, zum anderen ein ungewolltes Zurückschwenken des Betätigungselements 4 aus der Kontaktstellung in die Einführstellung nach dem Kontaktieren eines anzuschließenden Leiters verhindert wird.On an end face of the actuating element 4 ribs 17 are formed in the upper region, which together with the upper edge of the housing 2 form a two-stage latching. Thereby, the actuating element 4 can be fixed both in the insertion position and in the contact position, so that on the one hand there is the possibility to fix the electrical terminal 1 when delivering to customers in the insertion position, on the other hand an unwanted pivoting back of the actuator 4 from the contact position is prevented in the insertion after contacting a conductor to be connected.

Der Fig. 3 ist darüber hinaus entnehmbar, daß die Leiteraufnahme 6 als Langloch ausgebildet ist und in einer Aufnahmetasche 18 endet, wobei die Aufnahmetasche 18 im montierten Zustand des Betätigungselements 4 in der elektrischen Klemme 1 unterhalb des Schneidelements 5 angeordnet ist. Die Aufnahmetasche 18 dient dabei als Anschlaghilfe für den Monteur beim Einführen eines Leiters in die Leiteraufnahme 6. Ist das Ende des Leiters bis in die Aufnahmetasche 18 eingeführt, so ist sichergestellt, daß beim Verschwenken des Betätigungselements 4 in die Kontaktstellung der Leiter von dem Schneidelement 5 ordnungsgemäß erfaßt und somit die Seele des Leiters elektrisch kontaktiert wird.Of the Fig. 3 In addition, it can be seen that the conductor receiving 6 is formed as a slot and ends in a receiving pocket 18, wherein the receiving pocket 18 is disposed in the assembled state of the actuating element 4 in the electrical terminal 1 below the cutting element 5. If the end of the conductor is inserted into the receiving pocket 18, then it is ensured that upon pivoting of the actuating element 4 in the contact position of the conductor of the cutting element. 5 properly detected and thus the soul of the conductor is electrically contacted.

Zur weiteren Reduzierung der Baubreite der elektrischen Klemme 1 weist die Leiteraufnahme 6 eine offene Längsseite auf, wodurch die Breite des Betätigungselements 4, bei unverändertem maximalen Querschnitt eines anzuschließenden Leiters, verringert werden kann. Die Führung des anzuschließenden Leiters wird dann auf dieser Seite durch die Seitenwand 10 des Gehäuses 2 realisiert.To further reduce the width of the electrical terminal 1, the conductor receptacle 6 on an open longitudinal side, whereby the width of the actuating element 4, with unchanged maximum cross section of a conductor to be connected, can be reduced. The guidance of the conductor to be connected is then realized on this side by the side wall 10 of the housing 2.

Zur einfachen Handhabung ist in dem Betätigungselement 4 nicht nur die Leiteraufnahme 6 sondern zusätzlich noch eine weitere Aufnahme 19 zum Eingriff eines Hilfsmittels vorgesehen. Bei dem Hilfsmittel kann es sich beispielsweise um die Spitze eines Schraubendrehers handeln, der in die Aufnahme 19 eingesteckt wird, so daß dann mit Hilfe des Schraubendrehers das Betätigungselement 4 aus der ersten Stellung in die zweite Stellung, oder umgekehrt, verbracht werden kann. Durch die sich nach unten verjüngende Form der Betätigungselemente 4 können diese einfach von oben in die entsprechende Öffnung in dem Gehäuse 2 eingesetzt werden, was grundsätzlich auch bei geschlossenem Gehäuse 2 möglich ist, so daß die Seitenwand 10 des Gehäuses zur Montage der Betätigungselemente 4 nicht entfernt werden mußFor ease of handling not only the conductor receiving 6 but also a further receptacle 19 is provided for engaging an aid in the actuator 4. The tool may be, for example, the tip of a screwdriver, which is inserted into the receptacle 19, so that then with the help of the screwdriver, the actuator 4 from the first position to the second position, or vice versa, can be spent. By downwardly tapering shape of the actuators 4, these can be easily inserted from above into the corresponding opening in the housing 2, which is basically possible even with the housing 2 closed, so that the side wall 10 of the housing for mounting the actuators 4 is not removed must become

Schließlich ist insbesondere im Zusammenhang mit der Fig. 2 erkennbar, daß die Betätigungselemente 4 derart ausgebildet und in dem Gehäuse 2 angeordnet sind, daß eine optische Unterscheidung der Einführstellung von der Kontaktstellung einfach möglich ist. Bei dem in Fig. 2 links dargestellten Betätigungselement 4, das sich in der Einführstellung befindet, steht der obere Rand 20 des Betätigungselements 4 deutlich über den oberen Rand des Gehäuses 2 über. Im Unterschied dazu ist bei dem in Fig. 2 rechts dargestellten Betätigungselement 4, das in der Kontaktstellung verrastet ist, der obere Rand 20 des Betätigungselement 4 bündig zu dem oberen Rand des Gehäuses 2. Damit kann der Monteur auch optisch die jeweilige Stellung des Betätigungselements 4 leicht erkennen.Finally, in particular in connection with the Fig. 2 recognizable that the actuating elements 4 are formed and arranged in the housing 2, that a visual differentiation of the insertion position of the contact position is simply possible. At the in Fig. 2 Left illustrated actuator 4, which is located in the insertion position, the upper edge 20 of the actuating element 4 is clearly above the upper edge of the housing 2 via. In contrast, in the case of Fig. 2 right illustrated actuator 4, which is locked in the contact position, the upper edge 20 of the actuator 4 flush with the upper edge of the housing 2. Thus, the fitter can also visually recognize the respective position of the actuator 4 easily.
