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, in deren Wegbahn im Klemmkäfig ein Druckstück für die Leiter­klemmung drehbar gehalten ist, dem eine Feder für seine Rück­führung in die Offenstellung zugeordnet ist. Bei einer be­kannten Klemmvorrichtung der gattungsgemäßen Art (DE 23 57 091 B2) wird zwar mittels der Feder erreicht, daß das Druckstück geführt wird und auch in die Offenstellung der Klemmstelle rückgeführt werden kann, jedoch muß hierzu eine gesonderte Feder in den Innenraum des Klemmkäfigs hineinpraktiziert werden, was nicht nur platzaufwendig ist, sondern auch zu einer komplizierten Montage einer derartigen Klemmvorrichtung führt.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, in the path of which a pressure piece for the conductor clamping is held rotatably in the clamping cage and a spring for its return is assigned to the open position. In a known clamping device of the generic type (DE 23 57 091 B2) it is achieved by means of the spring that the pressure piece is guided and can also be returned to the open position of the clamping point, but for this purpose a separate spring must be practiced in the interior of the clamping cage , which is not only space-consuming, but also leads to a complicated assembly of such a clamping device.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Klemmvorrichtung der gattungsgemäßen Art zu schaffen, die bei verringertem Raumbedarf erheblich einfacher herzustellen ist.The present invention is therefore based on the object of providing a clamping device of the generic type which is considerably 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 seine 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 außerordent­ lich platzsparend, da sich die Feder nun nicht mehr im inneren Aufnahmeraum des Klemmkäfigs 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 its open position inside the clamping cage is eliminated. 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 extraordinary Lich space-saving, since the spring is no longer in the inner receiving space of the clamping 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, im wesentlichen parallel zur Einsteck­aufnahme für den Leiter orientierter 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 sehr eng aneinander heranrücken lassen. Gemäß einer weiteren bevorzugten Ausgestaltung ist das Druck­stück ein Doppelarmhebel und die Beaufschlagungszone der Klemm­schraube am Doppelarmhebel liegt auf der gleichen Seite der Drehachse des Doppelarmhebels wie die Klemmzone des Doppelarm­hebels bezüglich des Leiters, während die Beaufschlagungszone der Feder auf der gegenüberliegenden Seite der Drehachse des Doppelarmhebels vorgesehen ist. Auch diese bauliche Ausge­staltung trägt zu einer besonders kompakten platzsparenden Bauweise bei und hat darüber hinaus den weiteren erheblichen Vorteil, daß die Klemmung 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 größen dimensionierten Klemmvorrichtungen jedweder Einfluß der Feder auf den Klemmvorgang in vorteilhafter Weise praktisch ausgeschaltet.According to a particularly preferred embodiment, the pressure piece is an elongated lever oriented essentially parallel to the insertion receptacle for the conductor, to which the molded-on 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. According to a further preferred embodiment, the pressure piece is a double arm lever and the zone of application of the clamping screw on the double arm lever is on the same side of the axis of rotation of the double arm lever as the zone of clamping of the double arm lever with respect to the conductor, while the zone of application of the spring is provided on the opposite side of the axis of rotation of the double arm lever . This structural design also contributes to a particularly compact, space-saving design and also has the further considerable advantage that the clamping of the conductor practically results 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 Clamping cage takes place, 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 practically eliminated, even with large-sized clamping devices.

Ein bevorzugtes Ausführungsbeispiel einer Klemmvorrichtung gemäß der Erfindung wird nachstehend unter Bezugnahme auf die Zeichnung näher beschrieben.
Es zeigen

  • Figur 1 eine teilweise gebrochene Seitenansicht einer Klemm­vorrichtung gemäß der Erfindung mit Illustration unterschiedlicher Stellungen der betroffenen Wirk­elemente,
  • Figur 2 eine Draufsicht auf die Klemmvorrichtung nach Figure 1.
A preferred embodiment of a clamping device according to the invention is described below with reference to the drawing.
Show it
  • FIG. 1 shows a partially broken side view of a clamping device according to the invention, illustrating different positions of the active elements concerned,
  • Figure 2 is a plan view of the clamping device according to Figure 1.

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 Druck­ stück 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 Strom­ schiene 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 essentially parallel to the insertion receptacle 5 of the clamping cage 1, the pressure presses piece 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 contact 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 smaller one 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 the electrical conductor 6 to be connected is clamped, this means a direct frictional connection from the corresponding effective end of the clamping screw 7 via the upper one Part of the pressure piece 7, just the conductor 6 and finally the current rail 11, in particular excluding the spring 12. When pivoting the pressure piece 7 in the sense of the conductor clamping, the spring 12 is spread a little outwards under appropriate tension from the end region of the pressure piece opposite the clamping zone, this small spreading, also in connection with the relative Large length of the spring 12 extending parallel to the pressure piece 7 is sufficient, in conjunction with the lever arm, which exists between the loading zone 14 and the axis of rotation 8, the pressure piece 7 when the clamping screw 4 is screwed back, releasing the electrical conductor 6 into its open position to follow.
