Abstract

An arrangement for clamping an electric conductor includes a clamping cage having a threaded bore centered on a central axis. A clamping screw is received in the threaded bore for threading in and out along a predetermined path centered on the central axis. An insertion receptacle for the electric conductor is accommodated in the clamping cage and extends substantially parallel to the central axis. A pressure member is mounted in the clamping cage for pivoting about a pivot axis out of and back into an open position thereof and extends into the predetermined path. A spring urges the pressure member toward its open position. The spring is an integral unitary portion of the clamping cage and extends from an outer contour of the clamping cage towards the pressure member.

Description

Die Erfindung betrifft eine Klemmvorrichtung mit einem Klemmkäfig, in den eine Klemmschraube im wesentlichen parallel zu einer im Klemmkäfig vorgesehenen Einsteckaufnahme für einen anzuschließenden elektrischen Leiter eingeschraubt ist, und mit einem Druckstück, das in dem Klemmkäfig in Richtung auf den eingelegten elektrischen Leiter im Sinne seiner Klemmung drehbar gehalten ist und das in die Wegbahn der Klemmschraube ragt, die auf das Druckstück im Sinne der Leiterklemmung einwirkt, wobei auf das Druckstück ferner eine Feder im Sinne seiner Rückführung in die Offenstellung der Klemmvorrichtung einwirkt. Bei einer bekannten Klemmvorrichtung der gattungsgemäßen Art (DE-A-23 57 091) wird zwar durch die Feder die Rückführung des Druckstückes und damit der Klemmvorrichtung in die Offenstellung erreicht, jedoch muß dort eine gesonderte Feder in den Innenraum des Käfigs hineinpraktiziert werden, was platzaufwendig ist und einen komplizierten Montagevorgang erfordert.The invention relates to a clamping device with a clamping cage, in which a clamping screw is screwed substantially parallel to an insertion receptacle provided in the clamping cage for an electrical conductor to be connected, and with a pressure piece which is in the clamping cage in the direction of the inserted electrical conductor in the sense of its clamping is rotatably held and protrudes into the path of the clamping screw, which acts on the pressure piece in the sense of the conductor clamping, a spring also acting on the pressure piece in the sense of its return to the open position of the clamping device. In a known clamping device of the generic type (DE-A-23 57 091), the return of the pressure piece and thus the clamping device to the open position is achieved by the spring, but a separate spring must be practiced in the interior of the cage, which takes up a lot of space is and requires a complicated assembly process.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Klemmvorrichtung der gattungsgemäßen Art zu schaffen, die bei verringertem Raumbedarf einfacher herzustellen ist.The present invention is therefore based on the object to provide a clamping device of the generic type which is easier to manufacture with a reduced space requirement.

Die erfindungsgemäße Lösung besteht im wesentlichen darin, daß die Feder einstückig mit dem Klemmkäfig ausgebildet und von dessen Außenkontur an das Druckstück herangeführt ist. Die Herstellung einer derartigen Klemmvorrichtung ist insbesondere dadurch erheblich vereinfacht, daß die Montage einer gesonderten Feder für die Rückführung des Druckstückes in die Offenstellung im Inneren des Klemmkäfigs in Fortfall kommt. Demgegenüber verkompliziert sich die Herstellung des Klemmkäfigs durch die Anformung der Feder nur sehr unwesentlich, insbesondere auch deshalb, weil üblicherweise derartige Klemmkäfige als Stanz-Biegeteile ausgebildet sind, an denen die zusätzliche Ausbildung einer Feder auf sehr einfache Weise möglich ist. Die Anordnung ist auch außerordentlich platzsparend, da sich die Feder nun nicht mehr im inneren Aufnahmeraum des Käfigs befindet, sondern von der Außenkontur her, wo systembedingt entsprechender Platz zur Verfügung steht, an das Druckstück herangeführt ist.The solution according to the invention consists essentially in that the spring is formed in one piece with the clamping cage and is guided from its outer contour to the pressure piece. The manufacture of such a clamping device is in particular considerably simplified in that the assembly of a separate spring for returning the pressure piece to the open position inside the clamping cage is omitted is coming. In contrast, the manufacture of the clamping cage is only very insignificantly complicated by the shaping of the spring, in particular also because clamping cages of this type are usually designed as punched and bent parts on which the additional formation of a spring is possible in a very simple manner. The arrangement is also extremely space-saving, since the spring is no longer located in the inner receiving space of the cage, but is guided to the pressure piece from the outer contour, where appropriate space is available due to the system.

Gemäß einer besonders bevorzugten Ausgestaltung ist das Druckstück ein länglicher, in seiner Offenstellung im wesentlichen parallel zur Einsteckaufnahme für den Leiter liegender Hebel, zu dem sich die angeformte Feder ihrerseits im wesentlichen parallel erstreckt und ihn mit einem abgewinkelten Endstück hintergreift. Dank dieser Ausgestaltung baut die Klemmvorrichtung in besonderem Maße schmal und kompakt, da sich Einsteckaufnahme, Klemmschraube, Druckstück und Feder räumlich sehr eng aneinander heranrücken lassen. Gemäß einer weiteren bevorzugten Ausgestaltung ist das Druckstück ein Doppelarmhebel und die Beaufschlagungszone der Klemmschraube und die Klemmzone bezüglich des anzuschließenden elektrischen Leiters sind an dem einen Arm des Doppelarmhebels und die Beaufschlagungszone der Feder an dem anderen Arm des Doppelarmhebels vorgesehen. Auch diese bauliche Ausgestaltung trägt zu einer kompakten platzsparenden Bauweise bei und hat darüber hinaus den weiteren erheblichen Vorteil, daß die Klemme des Leiters praktisch in einem direkten Kraftkurzschluß zwischen dem Wirkende der Klemmschraube, dem Druckstück, dem Leiter und der entsprechenden Gegenlagerfläche für den Leiter am Klemmkäfig erfolgt, insbesondere ohne direkten Zwischenschluß der Feder, deren Kraft nur über einen entsprechenden Hebelarm zur Drehachse einfließt. Damit ist selbst bei größer dimensionierten Klemmvorrichtungen jedweder Einfluß der Feder auf den Klemmvorgang in vorteilhafter Weise praktisch ausgestaltet.According to a particularly preferred embodiment, the pressure piece is an elongated lever which, in its open position, lies essentially parallel to the insertion receptacle for the conductor, to which the molded spring in turn extends essentially parallel and engages behind it with an angled end piece. Thanks to this design, the clamping device is particularly narrow and compact, since the insertion receptacle, clamping screw, pressure piece and spring can be moved very closely together in space. According to a further preferred embodiment, the pressure piece is a double arm lever and the application zone of the clamping screw and the clamping zone with respect to the electrical conductor to be connected are provided on one arm of the double arm lever and the application zone of the spring on the other arm of the double arm lever. This structural design also contributes to a compact, space-saving design and also has the further considerable advantage that the terminal of the conductor is practically in a direct force short circuit between the effective end of the clamping screw, the pressure piece, the conductor and the corresponding counter bearing surface for the conductor on the clamping cage, in particular without a direct intermediate connection of the spring, the force of which flows into the axis of rotation only via a corresponding lever arm. This means that any influence of the spring on the clamping process is advantageously designed practically, even with larger clamping devices.

Die Klemmvorrichtung beinhaltet einen Klemmkäfig 1, der in bekannter Weise als Stanz-Biegeteil aus Blech geformt ist, wobei aus dem Zuschnitt im oberen Bereich ein Überlappungsteil 2 gebildet ist, das mit einem Gewinde 3 versehen ist, in das die Klemmschraube 4 eingeschraubt ist. In dem Klemmkäfig 1 ist eine Einsteckaufnahme 5 für einen hier einzustekkenden, anzuschließenden elektrischen Leiter 6 gebildet. Zur Festsetzung des eingesteckten elektrischen Leiters 6 ist in dem Klemmkäfig 1 ein Druckstück 7 drehbar gelagert, das im dargestellten Ausführungsbeispiel als länglicher Hebel, insbesondere Doppelarmhebel ausgebildet ist, dessen Drehachse 8 im unteren, dem Eintritt der Klemmschraube 4 abgewandten Endbereich des Klemmkäfigs 1 liegt. Das Druckstück 7 wird durch Einschrauben der Klemmschraube 4 von derem unteren Wirkende längs einer Beaufschlagungszone 9 beaufschlagt. Da das Druckstück länglich und im wesentlichen parallel zur Einsteckaufnahme 5 des Klemmkäfigs 1 orientiert ist, drückt das Druckstück 7 dann umgehend und unmittelbar den eingesteckten Leiter mit einer entsprechenden Klemmzone 10 beispielsweise gegen einen im Klemmkäfig 1 vorgesehenen Stromschienenabschnitt 11. Dadurch, daß die Beaufschlagungsfläche 9 am Druckstück 7 einen relativ großen Abstand zur Drehachse 8 haben kann, ergibt sich eine gute Leiteranpressung bei kleiner Schraubkraft selbst dann, wenn die Achse der Klemmschraube 4 nur wenig versetzt zur Drehachse 8 des Druckstückes 7 verläuft. Zur von der Stellung der Klemmschraube 4 abhängigen Zwangsführung des Druckstückes 7 und insbesondere für seine die Leitereinsteckung erleichternde automatische Rückführung in die Offenstellung ist eine Feder 12 vorgesehen, die in baulich einfacher Weise unmittelbar an den Klemmkäfig 1 angeformt ist, und zwar, wie im dargestellten Ausführungsbeispiel gezeigt, zweckmäßig an den oberen, das Gewinde 3 für die Klemmschraube 4 aufweisenden Überlappungsteil 2 des Klemmkäfigs 1. Die Feder 12 ist dabei von der Außenkontur des Klemmkäfigs 1 an das Druckstück 7 herangeführt. Besonders zweckmäßig verläuft dabei die Feder 12 von ihrem oberen Anformungsbereich zunächst im wesentlichen parallel zu dem länglichen Druckstück 7 und sie untergreift dieses dann mit einem abgewinkelten Ende 13. Auf diese Weise liegt die Beaufschlagungszone 14 des Druckstückes 7 für die Feder 12 auf der gegenüberliegenden Seite der Drehachse 8, bezogen auf die Beaufschlagungsfläche 9 für die Klemmschraube 4 und bezogen auf die Klemmzone 10 für den anzuschließenden Leiter 6 an diesem Druckstück 7. Bei der Klemmung des anzuschließenden elektrischen Leiters 6 bedeutet dieses einen direkten Kraftschluß vom entsprechenden Wirkende der Klemmschraube 7 über den oberen Teil des Druckstückes 7, eben den Leiter 6 und schließlich die Stromschiene 11, insbesondere unter Ausschluß der Feder 12. Die Feder 12 wird beim Verschwenken des Druckstückes 7 im Sinne der Leiteranklemmung vom der Klemmzone gegenüberliegenden Endbereich des Druckstückes unter entsprechender Anspannung ein wenig nach außen gespreizt, wobei diese kleine Abspreizung, auch in Verbindung mit der relativ großen Länge der sich parallel zum Druckstück 7 erstreckenden Feder 12 völlig aufreicht, in Verbindung mit dem Hebelarm, der zwischen der Beaufschlagungszone 14 und der Drehachse 8 besteht, das Druckstück 7 beim Zurückschrauben der Klemmschraube 4 dieser unter Freigabe des elektrischen Leiters 6 bis in seine Offenstellung folgen zu lassen.The clamping device includes a clamping cage 1, which is formed in a known manner as a stamped and bent part made of sheet metal, an overlap part 2 being formed from the cut in the upper region and provided with a thread 3 into which the clamping screw 4 is screwed. An insertion receptacle 5 for an electrical conductor 6 to be plugged in here to be connected is formed in the clamping cage 1. To fix the inserted electrical conductor 6, a pressure piece 7 is rotatably mounted in the clamping cage 1, which in the illustrated embodiment is designed as an elongated lever, in particular a double-arm lever, the axis of rotation 8 of which lies in the lower end region of the clamping cage 1 facing away from the entry of the clamping screw 4. The pressure piece 7 is acted upon by screwing in the clamping screw 4 from its lower active end along an application zone 9. Since the pressure piece is elongated and oriented essentially parallel to the insertion receptacle 5 of the clamping cage 1, the pressure piece presses 7 then immediately and immediately the plugged-in conductor with a corresponding clamping zone 10, for example against a busbar section 11 provided in the clamping cage 1. The fact that the loading surface 9 on the pressure piece 7 can have a relatively large distance from the axis of rotation 8 results in a good conductor pressure with a small screwing force even if the axis of the clamping screw 4 is only slightly offset from the axis of rotation 8 of the pressure piece 7. For the dependent guidance of the position of the clamping screw 4 of the pressure piece 7, and in particular for its automatic return to the open position, which facilitates the insertion of the conductor, a spring 12 is provided, which is integrally formed on the clamping cage 1 in a structurally simple manner, as in the exemplary embodiment shown shown, expediently on the upper, the thread 3 for the clamping screw 4 overlap part 2 of the clamping cage 1. The spring 12 is brought from the outer contour of the clamping cage 1 to the pressure piece 7. Particularly expediently, the spring 12 initially runs essentially parallel to the elongated pressure piece 7 from its upper shaping area and then engages under it with an angled end 13. In this way, the loading zone 14 of the pressure piece 7 for the spring 12 lies on the opposite side of the Axis of rotation 8, based on the contact surface 9 for the clamping screw 4 and based on the clamping zone 10 for the conductor 6 to be connected to this pressure piece 7. When clamping the electrical conductor 6 to be connected, this means a direct frictional connection from the corresponding active end of the clamping screw 7 via the upper Part of the pressure piece 7, just the conductor 6 and finally the busbar 11, in particular with the exclusion of the spring 12. The spring 12 is spread a little outwards when the pressure piece 7 is pivoted in the sense of the conductor clamping from the end region of the pressure piece opposite the clamping zone under appropriate tension, this small spreading, also in connection with the relatively large one Length of the spring 12 extending parallel to the pressure piece 7 is completely sufficient, in connection with the lever arm, which exists between the loading zone 14 and the axis of rotation 8, the pressure piece 7, when the screw 4 is screwed back, follow it with the release of the electrical conductor 6 into its open position allow.
