Abstract
Description
Die Erfindung betrifft eine elektrische Klemme, mit einem Federkraftklemmanschluss in einem Isolierstoffgehäuse für den Anschluss eines elektrischen Leiters an eine in dem Isolierstoffgehäuse des Federkraftklemmanschlusses angeordneten Stromschiene, wobei der Federkraftklemmanschluss als Käfigzugfeder ausgebildet ist, die in einem Kontaktkäfig eingesetzt und deren Klemmschenkel über eine Gewindeschraube bewegbar ist.The The invention relates to an electrical clamp with a spring force clamping connection in an insulating housing for connection an electrical conductor to one in the insulating housing the Federkraftklemmanschlusses arranged busbar, wherein the Federkraftklemmanschluss designed as a cage tension spring is inserted in a contact cage and the clamping legs over a threaded screw is movable.
Anschlussklemmen mit Federkraftklemmanschlüssen, insbesondere für Leitungsquerschnitte unter 35 qmm sind in der Regel manuell bedienbar, um ihre Öffnung und Schließung zu erreichen. Anschlussklemmen mit Leitungsquerschnitten über 35 qmm können als Hochstromklemmen bezeichnet werden, deren komfortable Bedienbarkeit jedoch in der Praxis durch die auftretenden hohen Klemmkräfte problematisch ist. Speziell bei Käfigzugfedern sind für den Krafthub, der mit einem herkömmlichen Schraubendreher durch Einstecken zu ihrer Betätigung erreicht werden kann, Grenzen gesetzt. Ohne Unterstützung durch Übersetzungen bspw. Vorschubgewinde, wäre der erforderliche Kraftaufwand für größere Querschnitte nicht gut realisierbar.terminals with spring clamps, especially for Conductor cross sections below 35 qmm are usually manually operated to to reach their opening and closing. terminals with cable cross sections over 35 qmm can as High current terminals are called, their comfortable operation however, in practice by the high clamping forces that occur is problematic. Especially with cage tension springs are for the power stroke, with a conventional screwdriver can be achieved by plugging in to their operation, Set limits. Without translation support For example. Feed thread, would be the required force for larger cross sections are not easy to realize.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine elektrische Anschlussklemme mit Federkraftklemmanschluss zu entwickeln, die trotz Bedienungshilfe über ein Vorschubgewinde niedrig baut.The Object of the present invention is to provide an electrical To develop terminal with spring terminal connection, the despite operator assistance low builds on a feed thread.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des 1. Anspruchs gelöst bzw. durch die abhängigen Unteransprüche in vorteilhafter Weise weitergebildet. Zur Lösung der Aufgabe ist die Käfigzugfeder über den Klemmschenkel mit einer Gewindemutter verbunden, wobei die Gewindemutter verdrehsicher in dem Isolierstoffgehäuse längsverschieblich geführt ist und das Öffnen des Klemmanschlusses zur Aufnahme des elektrischen Leiters durch Zug der Gewindemutter am Klemmschenkel erfolgt. Hierbei ist der Weg der Gewindemutter beschränkt auf die Strecke, die vertikal zurückgelegt werden muss, um das Durchstreckfenster für den elektrischen Leiter im Klemmschenkel zu öffnen. Diese Strecke liegt innerhalb des Bereichs der nutzbaren Länge des Gewindes der Gewindeschraube. Somit wird weniger Platz in der Höhe gebraucht, als die im Stand der Technik beschriebenen Lösungen zeigen.These The object is achieved by the features of the 1st claim or solved by the dependent Subclaims advantageously developed. to Solution of the task is the cage tension spring over the clamping leg connected to a threaded nut, wherein the threaded nut against rotation in the insulating housing longitudinally displaceable is guided and the opening of the terminal connection for receiving the electrical conductor by pulling the threaded nut takes place on the clamping leg. Here is the way of the nut limited to the distance traveled vertically must be to the pass-through window for the electrical conductor to open in the clamping leg. This route is within the range of the usable length of the thread of the threaded screw. Thus, less space is needed in height than the show solutions described in the prior art.
In einer weiteren vorteilhaften Gestaltung der Erfindung ist die Käfigzugfeder mit einem verlängerten Klemmschenkel ausgerüstet. Dieser erlaubt die direkte Anbindung der Klemme an Gewindemutter und gleichzeitig kann die Käfigzugfeder vorteilhafterweise in einem Stück gefertigt werden.In Another advantageous embodiment of the invention is the cage tension spring equipped with an extended clamping leg. This allows the direct connection of the clamp to threaded nut and At the same time, the cage tension spring advantageously be made in one piece.
Ein weiterer Bedienvorteil ergibt sich gemäß Anspruch 3, wobei an die Gewindemutter in maximaler Auslenkung des Klemmschenkels eine lösbare Arretiervorrichtung angreift. Dies nimmt dem Monteur den Druck vom Schraubendreher, mit dem er die Gewindeschraube zur Öffnung des Klemmbereichs betätigt und gibt ihm Zeit für das präzise Einstecken des Leiters in die Klemme.One further operating advantage results in accordance with the claim 3, wherein the threaded nut in maximum deflection of the clamping leg a releasable locking device attacks. This takes that Installer the pressure from the screwdriver with which he threaded the screw to open the clamping area is actuated and gives Give him time for the precise insertion of the conductor in the terminal.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen für eine Leiterplattenklemme näher erläutert. Es zeigen:following An embodiment of the invention with reference to the drawings for a circuit board clamp explained in more detail. Show it:
