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 material housing for the Connection of an electrical conductor to one in the insulating housing of the spring terminal connection arranged busbar, the Federkraftklemmanschluss as cage tension is formed, which are used in a contact cage and the clamping legs via a threaded screw is movable.
Anschlussklemmen mit Federkraftklemmanschlüssen, insbesondere für Leitungsquerschnitte unter 35qmm sind in der Regel manuell bedienbar, um ihre Öffnung und Schließung zu erreichen. Anschlussklemmen mit Leitungsquerschnitten über 35qmm 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. Beispiel dafür sind die DE-U 10 2005 058 307 und die DE-U 202 14 817. Eine andere bekannte Art der Federkraftklemmung ist die des Zugbügelanschlusses, siehe DE-C 198 17 924, der mit vorgespannten zylindrischen Druckfedern arbeitet, welche im Zugbügel eingebaut sind und das untere Ende des Zugbügels gegen die Unterseite einer Sromschiene zieht, so dass ein dort eingeführter Leiter gegen die Unterseite der Stromschiene verklemmt wird. Die Unterstützung beim Öffnen der Klemme erfolgt auch hier über ein Vorschubgewinde. Durch Zurhilfenahme von Vorschubgewinden geht jedoch eine nicht immer akzeptabele Zunahme der Bauhöhe einher, da die Schraube sich in ihrer Schraubgewindehülse auf und abwärts bewegt.terminals with spring-cage connections, especially for Cable cross sections below 35qmm are usually manually operated to her mouth and closure to reach. Terminals with cable cross-sections over 35qmm can be referred to as high-current terminals, their convenient operation However, problematic in practice by the high clamping forces occurring is. Especially with cage tension springs are for the power stroke, with a conventional screwdriver by plugging in for their operation can be achieved, limits set. Without translation support For example, feed thread, would be the required effort for larger cross sections not very feasible. Examples of this are DE-U 10 2005 058 307 and DE-U 202 14 817. Another known type of Federkraftklemmung is that of the drawbar connection, see DE-C 198 17 924, with preloaded cylindrical compression springs works, which built in the drawbar are and the lower end of the pull handle against the bottom of a Pulls the power rail, so that a conductor introduced there against the bottom of the Busbar is jammed. Support for opening the clamp is also provided over here a feed thread. By the aid of feed threads goes however, a not always acceptable increase in height accompanied, as the screw moves up and down in its screw threaded sleeve.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine elektrische Anschlussklemme mit Fedrkraftklemmanschluss zu entwickeln, die trotz Bedienungshilfe über ein Vorschubgewinde niedrig baut.The Object of the present invention is to provide an electrical Terminal with Fedrkraftklemmanschluss to develop, despite operator assistance on a Feed thread low builds.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des 1. Anspruchs gelöst bzw. durch die abhängigen Unteransprüche in vorteilhafter Weise weitergebildet.These The object is achieved by the Features of the 1st claim solved or by the dependent ones under claims developed in an advantageous manner.
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 Durchsteckfenster 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.to solution the task is the cage tension spring over the Clamp leg connected to a threaded nut, the threaded nut is guided against rotation in the insulating housing longitudinally displaceable and opening of the terminal connection for receiving the electrical conductor by Pull the threaded nut on the clamping leg done. Here is the Path of the threaded nut limited on the track that has to be traveled vertically to get that Through window for to open the electrical conductor in the clamping leg. This route is located within the range of the usable length of the thread of the threaded bolt. Thus, less space in the height is needed than in the state the technology described solutions demonstrate.
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 with a lengthened Equipped clamping leg. This allows the direct connection of the clamp to threaded nut and at the same time the cage tension spring can advantageously in one piece be made.
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 according to claim 3, wherein the Threaded nut in maximum deflection of the clamping leg a releasable locking device attacks. This takes away the pressure from the screwdriver, with which he actuates the threaded screw for opening the clamping area and give him time for that precisely Insert the conductor into the terminal.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen für eine Leiterplattenklemme näher erläutert.following is an embodiment of Invention with reference to the drawings for a circuit board terminal explained in more detail.
