Description

Die Erfindung betrifft eine elektrische Anschlussklemmvorrichtung gemäß dem einleitenden Teil von Anspruch 1. Eine solche Anschlussklemmvorrichtung ist aus EP 0 418 766 A bekannt.The invention relates to an electrical terminal device according to the introductory part of claim 1. Such a terminal device is known from EP 0 418 766 A.

Bekanntlich werden solche elektrische Anschlussklemmvorrichtungen einzeln ausgeführt. Für jeden Anschluss wird eine Klemmvorrichtung mit einer Schraube und einem Klemmteil (auch Druckübertragungsteil genannt), vorgesehen. Die Klemmung erfolgt dabei über die Schraube, über die der erforderliche Klemmdruck aufgebracht wird. Dadurch wird das elektrische Kabel an einen leitenden Kontaktteil gedrückt, wodurch Strom fließen kann. Bei dieser Art der elektrischen Klemmung wird für jeden Anschluss eine Schraube verwendet. In Gehäusen, die in Schaltschränken eingebaut werden, sind aus Platzgründen die elektrischen Anschlüsse übereinander angeordnet. Wenn der untere Anschluss bereits angeschraubt ist, stellt sich das Problem, dass der obere Anschluss nicht mehr zugänglich ist.As is known, such electrical terminal devices are executed individually. For each connection, a clamping device with a screw and a clamping part (also called pressure transmission part) is provided. The clamping takes place via the screw, via which the required clamping pressure is applied. As a result, the electrical cable is pressed against a conductive contact part, whereby current can flow. With this type of electrical clamping, one screw is used for each connection. In housings that are installed in control cabinets, the electrical connections are arranged one above the other for reasons of space. If the lower connector is already screwed on, the problem arises that the upper connector is no longer accessible.

Aus der FR 2 449 979 A ist andererseits eine verbindungseinrichtung zum elektrischen Verbinden von zwei Kabeln miteinander bekannt. Dabei sind zwei schalenförmige Klemmteile vorgesehen, die mit Hilfe einer Schraube und einer darauf aufgeschraubten Mutter in Richtung aufeinander zu bewegt werden können. In diesen Klemmteilen sind in Ansicht halbkreisförmige, plattenförmige, metallische Verbindungsbacken beweglich angeordnet; diese Verbindungsbacken sind mit zwei beabstandeten Zahnabschnitten versehen, um bei den zu verbindenden, zwischen den Klemmteilen angeordneten Kabeln die Isolierungen zu durchdringen und die leitenden Adern zu kontaktieren, so dass diese über die Verbindungsbacke miteinander elektrisch verbunden werden.On the other hand, FR 2 449 979 A discloses a connection device for electrically connecting two cables to one another. In this case, two cup-shaped clamping parts are provided, which can be moved towards each other by means of a screw and a nut screwed thereon. In these clamping parts semi-circular, plate-shaped, metallic connecting jaws are movably arranged in view; these connecting jaws are provided with two spaced tooth portions to penetrate the insulators to be connected, arranged between the clamping parts cables and to contact the conductive wires, so that they are electrically connected to each other via the connecting jaw.

Aufgabe der Erfindung ist es, eine gattungsgemäße elektrische Anschlussklemmvorrichtung zu schaffen, bei der es auf einfache Weise möglich ist, zwei elektrische Kabel zu befestigen und anzuschließen.The object of the invention is to provide a generic electrical terminal device in which it is possible in a simple manner to attach and connect two electrical cables.

Diese Aufgabe wird erfindungsgemäß durch die in Anspruch 1 definierten Merkmale gelöst. Vorteilhafte Ausführungsformen bzw. Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by the features defined in claim 1. Advantageous embodiments and developments are specified in the dependent claims.

Bei der erfindungsgemäßen Anschlussklemmvorrichtung ist es mit Hilfe der beiden Anpressflächen des einen Klemmteils in vorteilhafter Weise möglich, zwei Kabel gleichzeitig und zuverlässig mit zwei gesonderten Kontakten in Verbindung zu bringen.In the terminal clamping device according to the invention, it is possible with the help of the two contact surfaces of a clamping part in an advantageous manner to bring two cables simultaneously and reliably with two separate contacts in combination.

Dabei ist es auch möglich, die zwei Kabel an Kontakten anzuschließen, die bei einer herkömmlichen Klemmvorrichtung nur schwer zugänglich sind; demgemäß können die zwei Kontakte in Klemmrichtung bzw. in Richtung der Schraubenbewegung hintereinander angeordnet sein.It is also possible to connect the two cables to contacts that are difficult to access in a conventional clamping device; Accordingly, the two contacts can be arranged one behind the other in the clamping direction or in the direction of the screw movement.

Um zumindest im Wesentlichen denselben Anpressdruck an den beiden Kontakten zu erreichen und somit zu verhindern, dass das eine Kabel (zu) fest gegen den einen Kontakt gedrückt wird, wogegen beim zweiten Kabel nur eine lose Kontaktierung vorliegt und die Gefahr besteht, dass die elektrische Verbindung nicht (zuverlässig) zustande kommt, ist es günstig, wenn der Klemmteil eine Wippe ist.In order to achieve at least substantially the same contact pressure on the two contacts and thus to prevent the one cable (too) is pressed firmly against the one contact, whereas the second cable is only a loose contact and there is a risk that the electrical connection not (reliably) comes about, it is advantageous if the clamping part is a rocker.

Zum Aufbringen eines einheitlichen Anpressdrucks auf beide Kontakte ist es auch günstig, wenn der Klemmteil an einer mittels der Schraube in einer Führung längsverstellbaren Lasche schwenkbar gelagert ist.To apply a uniform contact pressure on both contacts, it is also advantageous if the clamping part on a is mounted pivotably by means of the screw in a guide longitudinally adjustable tab.

Um einerseits den Anpressdruck des Klemmteils auf die beiden Kontakte in effizienter Weise herbeizuführen und andererseits die gleichmäßige Druckaufteilung auf beide Kontakte zu unterstützen, ist es vorteilhaft, wenn die Schwenkachse des Klemmteils im Wesentlichen senkrecht zur Längsachse der Schraube ist.On the one hand to bring about the contact pressure of the clamping part on the two contacts in an efficient manner and on the other hand to support the uniform pressure distribution on both contacts, it is advantageous if the pivot axis of the clamping part is substantially perpendicular to the longitudinal axis of the screw.

Für eine besonders einfache, kostengünstige Konstruktion ist es von Vorteil, wenn die Schraube direkt in der Lasche eingeschraubt ist.For a particularly simple, inexpensive construction, it is advantageous if the screw is screwed directly into the tab.

Um einen Stromfluss durch den Klemmteil zu unterbinden, wodurch die beiden elektrischen Kontakte kurzgeschlossen würden, kann einfach der Klemmteil aus isolierendem Material bestehen.In order to prevent a flow of current through the clamping part, whereby the two electrical contacts would be short-circuited, simply the clamping part made of insulating material.

Um eine stabile, kompakte Anordnung zu erlangen, ist es auch günstig, wenn der Klemmteil eine mittige Durchbrechung aufweist, die von einem der beiden Kontakte durchsetzt wird, wobei eine diesem Kontakt zugewandte Seitenwand der Durchbrechung eine der beiden Anpressflächen bildet.In order to obtain a stable, compact arrangement, it is also advantageous if the clamping part has a central opening which is penetrated by one of the two contacts, wherein a side wall of the opening facing this contact forms one of the two contact surfaces.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels, auf das sie jedoch nicht beschränkt sein soll, noch weiter erläutert. Im Einzelnen zeigen in der Zeichnung: Fig. 1 einen Längsschnitt einer erfindungsgemäßen elektrischen Klemmvorrichtung mit einem Kabel; und Fig. 2 einen Schnitt dieser elektrischen Klemmvorrichtung gemäß der Linie II-II in Fig. 1, jedoch ohne Kabel.The invention will be explained below with reference to a preferred embodiment shown in the drawing, to which, however, it should not be limited. 1 shows a longitudinal section of an electrical clamping device according to the invention with a cable; and Fig. 2 is a section of this electrical clamping device according to the line II-II in Fig. 1, but without cable.

Fig. 1 zeigt einen Längsschnitt einer elektrischen Klemmvorrichtung 1 mit einem Gehäuse 2. Das Gehäuse 2 weist zwei Öffnungen 3, 3' zum Einführen von Kabeln 4, 4' auf. Weiters ist im Gehäuse 2 eine stirnseitige Öffnung 5 für die Aufnahme einer Schraube 6 vorgesehen. Ein Kabel 4 ist durch die eine, vordere Ausnehmung 3 in das Innere des Gehäuses 2 eingeführt gezeigt, um mit einem vorderen Kontakt 7 von zwei hintereinander angeordneten Kontakten 7, 7' in Verbindung gebracht zu werden. Das andere Kabel 4' ist in der hinteren Ausnehmung 3' eingesteckt gezeigt.Fig. 1 shows a longitudinal section of an electrical clamping device 1 with a housing 2. The housing 2 has two openings 3, 3 'for the insertion of cables 4, 4'. Furthermore, an end opening 5 for receiving a screw 6 is provided in the housing 2. A cable 4 is shown inserted through the one, front recess 3 in the interior of the housing 2 to be associated with a front contact 7 of two consecutively arranged contacts 7, 7 'in connection. The other cable 4 'is shown inserted in the rear recess 3'.

Mittels der Schraube 6 wird eine Lasche 8 im Gehäuse 2 in einer Führung 9 im Gehäuse 2 in Richtung der Längsachse 6' der Schraube 6 verschoben, vgl. auch die Pfeile A in Fig. 1. In der Lasche 8 ist ein als Wippe ausgeführter Klemmteil 10 um eine Schwenkachse 10' schwenkbar gelagert. Der Klemmteil 10 weist zwei gewölbte Anpressflächen 11, 11' auf, wobei die hintere Anpressfläche 11' durch eine Seitenwand einer mittigen Durchbrechung 12 des Klemmteils 10 gebildet wird.By means of the screw 6, a tab 8 in the housing 2 is displaced in a guide 9 in the housing 2 in the direction of the longitudinal axis 6 'of the screw 6, cf. also the arrows A in Fig. 1. In the Tab 8 is designed as a rocker clamping part 10 about a pivot axis 10 'pivotally mounted. The clamping part 10 has two curved contact surfaces 11, 11 ', wherein the rear contact surface 11' is formed by a side wall of a central opening 12 of the clamping part 10.

Beim Anziehen der Schraube 6 wird nun die Lasche 8 in Richtung der Öffnung 5 in der Führung 9 gezogen, vgl. die Pfeile B in Fig. 1, wodurch sich die Anpressflächen 11 bzw. 11' den beiden Kontakten 7 bzw. 7' nähern und schlussendlich die Kabel 4, 4' mit gleichförmigem Anpressdruck gegen die Kontakte 7 bzw. 7' klemmen. Aufgrund der Schwenklagerung (vgl. auch den Pfeil B in Fig. 1) des Wippen-Klemmteils 10 in der Lasche 8 erfolgt eine gleichmäßige Druckaufteilung auf die beiden Kontakte 7, 7', und es wird somit verhindert, dass die Klemmung eines der Kabel 4 gegen einen der Kontakte 7, 7' bereits fest ist, während die andere Klemmung noch lose ist. Um kein Moment auf die in der Führung 9 im Gehäuse 2 linear geführten Lasche 8 zu erzeugen, schneiden die Längsachse 6' der Schraube 6 und die dazu senkrecht stehende Schwenkachse 10' des Klemmteils 10 einander.When tightening the screw 6, the tab 8 is now pulled in the direction of the opening 5 in the guide 9, see. the arrows B in Fig. 1, whereby the contact surfaces 11 and 11 ', the two contacts 7 and 7' approach and finally the cables 4, 4 'with uniform contact pressure against the contacts 7 and 7' terminals. Due to the pivotal mounting (cf also the arrow B in Fig. 1) of the rocker clamp member 10 in the tab 8 is a uniform pressure distribution on the two contacts 7, 7 ', and it is thus prevented that the clamping of one of the cable against one of the contacts 7, 7 'already fixed, while the other clamp is still loose. In order to generate no moment on the in the guide 9 in the housing 2 linearly guided tab 8, the longitudinal axis 6 'of the screw 6 and the perpendicular thereto pivot axis 10' of the clamping member 10 intersect each other.

Fig. 2 zeigt einen Schnitt der elektrischen Klemmvorrichtung gemäß der Linie II-II in Fig. 1, jedoch sind in Fig. 2 die Kabel 4, 4' weggelassen worden. Die Schraube 6 ist in die U-förmige Lasche 8 direkt eingeschraubt, welche in der Führung 9 im Gehäuse 2 geführt ist und somit über ein Verdrehen der Schraube 6 in der Art eines Spindeltriebs verschoben werden kann. Die Schraube 6 ist dabei gegen ein axiales Verstellen gesichert, beispielsweise indem sie mit ihrem vorderen (inneren) Ende am Kontakt 7 ansteht. Die U-förmige Lasche 8 nimmt über Lagerzapfen 8" an ihren beiden Schenkeln 8' den Klemmteil 10 um die Achse 10' schwenkbar auf. Weiters sind die beiden Kontakte 7, 7' ersichtlich, von denen sich der vordere, 7, im Raum zwischen den Laschen-Schenkeln 8' und der hintere, 7', durch die mittige Durchbrechung 12 des Wippen-Klemmteils 10 hindurcherstreckt. Zwischen dem Kontakt 7 und der Anpressfläche 11 sowie dem Kontakt 7' und der Anpressfläche 11' können die Kabel 4, 4' eingesetzt werden; es ist möglich, zwei Kabel 4, 4' oder auch nur ein Kabel 4 oder 4' entweder am Kontakt 7 oder 7' anzuschließen.Fig. 2 shows a section of the electrical clamping device according to the line II-II in Fig. 1, but in Fig. 2, the cables 4, 4 'have been omitted. The screw 6 is screwed directly into the U-shaped tab 8, which is guided in the guide 9 in the housing 2 and thus can be moved over a rotation of the screw 6 in the manner of a spindle drive. The screw 6 is secured against axial displacement, for example by being present with its front (inner) end on the contact 7. The U-shaped lug 8 pivotably receives the clamping part 10 about its bearing on the two legs 8 'about the axis 10. The two contacts 7, 7' can also be seen, of which the front, 7, in the space between the tab legs 8 'and the rear, 7', extends through the central opening 12 of the rocker clamping part 10. Between the contact 7 and the contact surface 11 and the contact 7 'and the contact surface 11', the cables 4, 4 ' It is possible to connect two cables 4, 4 'or just one cable 4 or 4' either at the contact 7 or 7 '.

Der Klemmteil 10 besteht aus isolierendem Material, um einen Stromfluss durch den Klemmteil 10 zu verhindern, bei dem eine Kurzschlussverbindung zwischen den beiden Kontakten 7 und 7' entstehen könnte.The clamping member 10 is made of insulating material to prevent current flow through the clamping member 10, in which a short-circuit connection between the two contacts 7 and 7 'could arise.
