VerbindungskiemmeConnecting gill
Die vorliegende Erfindung betrifft eine Verbindungsklemme für einen elektrischen Leiter mit einer Leiterachse, einem Leiterende und einem elektrisch isolierenden Mantel, mit einem elektrisch isolierenden Gehäuse und einem im Gehäuse zwischen einer Klemmstellung und einer Freigabestellung verdrehbaren Klemmelement, wobei durch Drehen des Klemmelements in dieThe present invention relates to a connecting terminal for an electrical conductor with a conductor axis, a conductor end and an electrically insulating jacket, with an electrically insulating housing and a clamping element rotatable in the housing between a clamping position and a release position, wherein by rotating the clamping element in the
Klemmstellung der in das Gehäuse eingeführte Leiter von dem Klemmelement gegen ein Gegenlager gedrückt, der Mantel des Leiters mittels einer Schneide durchtrennt und der Leiter gegen eine Kontaktfläche gedrückt wird, so daß der Leiter mit der Kontaktfläche elektrisch leitend verbunden wird.Clamping position of the conductor inserted into the housing is pressed by the clamping element against a counter bearing, the sheath of the conductor is cut by means of a cutting edge and the conductor is pressed against a contact surface, so that the conductor is electrically conductively connected to the contact surface.
Eine derartige Verbindungsklemme ist z.B. aus der DE 195 16 338 Cl bekannt.Such a connecting clamp is e.g. known from DE 195 16 338 Cl.
Bei der Verbindungsklemme des Standes der Technik ist es bereits möglich, den Leiter schraubenlos zu kontaktieren. Auch muß der Mantel nicht zuvor entfernt werden. Ein Abisolieren des Leiters ist also nicht mehr nötig. Die Verbindungsklemme des Standes der Technik ist aber nur in einem sehr engen Lei- terquerschnittsbereich einsetzbar, z.B. in einem Leiterquerschnittsbereich von 2 mm2 bis 21/. mm2.With the connecting clamp of the prior art, it is already possible to contact the conductor without screws. The coat also does not have to be removed beforehand. It is no longer necessary to strip the conductor. The connecting clamp of the prior art can, however, only be used in a very narrow conductor cross-sectional area, for example in a conductor cross-sectional area of 2 mm 2 to 2 1 /. mm 2 .
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Verbindungsklemme zu schaffen, die in einem weiten Leiter- querschnittsbereich einsetzbar ist. „Weit" bedeutet in diesemThe object of the present invention is to provide a connecting terminal which can be used in a wide range of conductor cross sections. "Far" means in this
Zusammenhang, daß mit der erfindungsgemäßen Verbindungsklemme Leiter mit einem Leiterquerschnittsverhältnis von mindestens 3:1, besser 5:1, sicher kontaktierbar sein sollen. Die Aufgabe wird dadurch gelöst, daß das Klemmelement und das Gegenlager relativ zueinander federnd gelagert sind. Denn dadurch wird beim Anschließen des Leiters eine definierte Kraft auf den Leiter ausgeübt. Ein Durchtrennen des Leiters aufgrund übermäßiger Krafteinwirkung ist ebenso ausgeschlossen wie ein Nichtdurchdringen des Mantels aufgrund unzureichender Krafteinwirkung. Somit sind mit der erfindungsgemäßen Verbindungsklemme Leiter in einem Leiterquerschnittsbereich von z.B. V- mm2 bis 2% mm2 klemmbar.Context that conductors with a conductor cross-sectional ratio of at least 3: 1, better 5: 1, should be able to be safely contacted with the connecting terminal according to the invention. The object is achieved in that the clamping element and the counter bearing are resiliently mounted relative to one another. Because this exerts a defined force on the conductor when connecting the conductor. Cutting the conductor due to excessive force is also excluded, as is not penetrating the sheath due to insufficient force. Thus, conductors in a conductor cross-sectional area of, for example, V mm 2 to 2% mm 2 can be clamped with the connecting clamp according to the invention.
Die federnde Lagerung kann z.B. dadurch erreicht werden, daß das Klemmelement ein Andrückelement aufweist und daß das Andrückelement in dem Klemmelement federnd gelagert ist.The resilient bearing can e.g. can be achieved in that the clamping element has a pressing element and that the pressing element is resiliently mounted in the clamping element.
Die Sicherheit für eine Bedienperson beim Überprüfen der Verbindungsklemme ist besonders hoch, wenn die Kontaktfläche in der Klemmstellung mit einem elektrischen Gegenleiter elektrisch leitend verbunden und in der Freigabestellung von dem Gegenleiter elektrisch getrennt ist.Safety for an operator when checking the connecting terminal is particularly high if the contact surface is electrically conductively connected to an electrical counter conductor in the clamping position and is electrically separated from the counter conductor in the release position.
Die Kontaktierung des Leiters erfolgt besonders zuverlässig, wenn das Leiterende in der Klemmstellung gegen einen im Gehäuse angeordneten Anschlag gedrückt wird.The contacting of the conductor is particularly reliable when the end of the conductor is pressed in the clamping position against a stop arranged in the housing.
Der Kontakt ist noch besser, wenn der Anschlag in der Klemmstellung mit der Kontaktfläche elektrisch leitend verbunden ist .The contact is even better if the stop is electrically conductively connected to the contact surface in the clamping position.
Wenn die Verbindungsklemme für Leiter mit einem maximalen Querschnitt ausgelegt ist und die Kontaktfläche in Richtung der Leiterachse gesehen eine mit dem maximalen Querschnitt korrespondierende Krümmung aufweist, ergibt sich beim Kontaktieren eine besonders große wirksame Kontaktfläche. Die Kontaktierung des Leiters ist noch zuverlässiger, wenn die Kontaktfläche spitze Erhebungen aufweist.If the connecting terminal is designed for conductors with a maximum cross section and the contact surface has a curvature corresponding to the maximum cross section when viewed in the direction of the conductor axis, a particularly large effective contact surface results when making contact. Contacting the conductor is even more reliable if the contact surface has pointed elevations.
Der Mantel kann wahlweise parallel oder quer zur Leiterachse durchtrennt werden.The sheath can either be cut parallel or across the conductor axis.

FIG 6 eine weitere Verbindungsklemme.6 shows a further connecting terminal.
Gemäß FIG 1 weist eine Verbindungsklemme ein elektrisch isolierendes Gehäuse 1 auf. Im Gehäuse 1 sind zwei Klemmelemente 2 angeordnet. Die Klemmelemente 2 sind zwischen einer Klemmstellung und einer Freigabestellung verdrehbar. In FIG 1 ist das linke Klemmelement 2 in seiner Klemmstellung und das rechte Klemmelement 2 in seiner Freigabestellung dargestellt.According to FIG. 1, a connecting terminal has an electrically insulating housing 1. Two clamping elements 2 are arranged in the housing 1. The clamping elements 2 can be rotated between a clamping position and a release position. 1 shows the left clamping element 2 in its clamping position and the right clamping element 2 in its release position.
Die Klemmelemente 2 weisen Andrückelemente 3 mit Kontaktflächen 3' auf. Die Andrückelemente 3 sind in den Klemmelementen 2 federnd gelagert. Die federnde Lagerung erfolgt über Druckfedern 4, mittels derer die Andrückelemente 3 in den Klemmelementen 2 vorgespannt gelagert sind. Die Klemmelemente 2 sind somit relativ zu Gegenlagern 5 federnd gelagert.The clamping elements 2 have pressing elements 3 with contact surfaces 3 '. The pressing elements 3 are resiliently mounted in the clamping elements 2. The resilient mounting takes place via compression springs 4, by means of which the pressing elements 3 are mounted in a preloaded manner in the clamping elements 2. The clamping elements 2 are thus resiliently mounted relative to counter bearings 5.
Die Kraft, mit der die Andrückelemente 3 beim Kontaktieren eines elektrischen Leiters 6 an diesen angedrückt werden, ist im wesentlichen unabhängig vom Leiterquerschnitt. Aufgrund dieser federnden Lagerung kann u.a. ein eventuelles Wegfließen einer Leiterisolierung ausgeglichen werden.The force with which the pressing elements 3 are pressed against an electrical conductor 6 when contacting it is essentially independent of the conductor cross section. by virtue of This resilient mounting can compensate for any flow of conductor insulation.
Wenn sich das Klemmelement 2 in seiner Freigabestellung - siehe FIG 2 - befindet, kann der Leiter 6 in die Verbindungsklemme eingeführt werden. Der Leiter 6 weist eine Leiterachse 7, ein Leiterende 8 und einem elektrisch isolierenden Mantel 9 auf.When the clamping element 2 is in its release position - see FIG. 2 - the conductor 6 can be inserted into the connecting clamp. The conductor 6 has a conductor axis 7, a conductor end 8 and an electrically insulating jacket 9.
Das Klemmelement 2 wird, z.B. mittels eines Schraubendrehers (dargestellt in den Figuren ist nur die Klinge des Schraubendrehers), in die Klemmstellung verdreht. Beim Drehen des Klemmelements 2 in die Klemmstellung wird zunächst der in das Gehäuse 1 eingeführte Leiter 6 von dem Klemmelement 2 gegen das Gegenlager 5 gedrückt. Diese Stellung ist in FIG 3 dargestellt.The clamping element 2 is e.g. by means of a screwdriver (shown in the figures only the blade of the screwdriver) is rotated into the clamping position. When the clamping element 2 is rotated into the clamping position, the conductor 6 inserted into the housing 1 is first pressed by the clamping element 2 against the counter bearing 5. This position is shown in FIG 3.
Beim Weiterdrehen des Klemmelements 2 wird dann der Mantel 9 des Leiters 6 mittels einer Schneide 10 durchtrennt und der Leiter 6 gegen die Kontaktfläche 3' gedrückt. Hierdurch wird der Leiter 6 mit der Kontaktfläche 3 ' elektrisch leitend verbunden .When the clamping element 2 is turned further, the jacket 9 of the conductor 6 is then cut by means of a cutting edge 10 and the conductor 6 is pressed against the contact surface 3 '. As a result, the conductor 6 is electrically conductively connected to the contact surface 3 '.
Sowohl die Kontaktfläche 3 ' als auch die Schneide 10 sind am Andrückelement 3 angeordnet. Das Andrückelement 3 bildet also ein kombiniertes Schneid- und Kontaktierwerkzeug, das im Klemmelement 2 federnd gelagert ist.Both the contact surface 3 'and the cutting edge 10 are arranged on the pressing element 3. The pressure element 3 thus forms a combined cutting and contacting tool which is resiliently mounted in the clamping element 2.
Die Kontaktfläche 3 ' ist in der Klemmstellung mit einem elek- trischen Gegenleiter 11 elektrisch leitend verbunden. DerIn the clamped position, the contact surface 3 'is electrically conductively connected to an electrical counter conductor 11. The
Strom fließt somit über den Leiter 6 und die Kontaktfläche 3 ' auf den Gegenleiter 11. Die Kontaktfläche 3' und der Gegenleiter 11 können permanent elektrisch leitend miteinander verbunden sein. Bevorzugt ist die Kontaktfläche 3' aber in der Freigabestellung von dem Gegenleiter 11 elektrisch getrennt .Current thus flows via the conductor 6 and the contact surface 3 'to the counter conductor 11. The contact surface 3' and the counter conductor 11 can be permanently connected to one another in an electrically conductive manner. However, the contact surface 3 'is preferably in the release position of the opposite conductor 11 is electrically isolated.
Der Leiter 6 wird beim Verdrehen des Klemmelements 2 ein Stück in die Verbindungsklemme eingezogen. Das Leiterende 8 wird dadurch in der Klemmstellung gegen einen Anschlag 12 gedrückt, der im Gehäuse 1 angeordnet ist. Auch der Anschlag 12 ist - zumindest in der Klemmstellung - mit der Kontaktfläche 3' elektrisch leitend verbunden.When the clamping element 2 is rotated, the conductor 6 is pulled a little into the connecting terminal. The conductor end 8 is thereby pressed in the clamping position against a stop 12 which is arranged in the housing 1. The stop 12 is also electrically conductively connected to the contact surface 3 ', at least in the clamping position.
Die Verbindungsklemme ist für Leiter 6 mit einem maximalen Querschnitt von z.B. 2V. mm2 ausgelegt. Um eine optimale Kon- taktierung des Leiters 6 zu erreichen, weist die Kontaktfläche 3 ' in Richtung der Leiterachse 7 gesehen eine Krümmung auf, die mit dem maximalen Querschnitt korrespondiert. Mit der Verbindungsklemme ist aber auch ein Leiter 6 mit einem Querschnitt von z.B. nur V2 mm2 gut kontaktierbar . Zur weiteren Verbesserung des elektrischen Kontakts zwischen Kontaktfläche 3 ' und Leiter 6 weist die Kontaktfläche 3 ' spitze Er- hebungen, z.B. Zacken, Rillen oder Krallen, auf.The connection terminal is for conductor 6 with a maximum cross section of 2V, for example. mm 2 designed. In order to achieve an optimal contacting of the conductor 6, the contact surface 3 ′ has a curvature, viewed in the direction of the conductor axis 7, which corresponds to the maximum cross section. However, a conductor 6 with a cross section of, for example, only V2 mm 2 can also be easily contacted with the connecting terminal. To further improve the electrical contact between contact surface 3 'and conductor 6, the contact surface 3' has pointed elevations, for example jags, grooves or claws.
Bei dem Ausführungsbeispiel gemäß den FIG 1 bis 5 wird der Leiter 6 durch die Schneide 10 quer zur Leiterachse 7 durchtrennt. In FIG 6 ist nun eine weitere Verbindungsklemme dar- gestellt. Bei dieser verläuft die Schneide 10 parallel zurIn the exemplary embodiment according to FIGS. 1 to 5, the conductor 6 is severed by the cutting edge 10 transversely to the conductor axis 7. A further connection terminal is now shown in FIG. In this, the cutting edge 10 runs parallel to
Leiterachse 7. Bei der Verbindungsklemme gemäß FIG 6 wird der Mantel 9 somit im wesentlichen parallel zur Leiterachse 7 durchtrennt. Der Mantel 9 wird dann von der Kontaktfläche 3' verdrängt. Bei der Verbindungsklemme gemäß den FIG 1 bis 5 hingegen wird der Mantel 9 von der Schneide 10 abgeschält. Auch sind die Druckfedern 4 bei der Verbindungsklemme gemäß FIG 6 als Blattfedern ausgebildet, während sie bei der Verbindungsklemme gemäß den FIG 1 bis 5 als Spiralfedern ausgebildet sind. Im übrigen sind die beiden Verbindungsklemmen gleich aufgebaut. Gleiche Elemente sind daher in FIG 6 mit den gleichen Bezugszeichen versehen wie in den FIG 1 bis 5. Conductor axis 7. In the connecting terminal according to FIG. 6, the jacket 9 is thus cut essentially parallel to the conductor axis 7. The jacket 9 is then displaced from the contact surface 3 '. In contrast, in the connecting clamp according to FIGS. 1 to 5, the jacket 9 is peeled off from the cutting edge 10. The compression springs 4 in the connection clamp according to FIG. 6 are also designed as leaf springs, while in the connection clamp according to FIGS. 1 to 5 they are designed as spiral springs. Otherwise, the two connection terminals built up the same. The same elements are therefore given the same reference numerals in FIG. 6 as in FIGS. 1 to 5.
