Description

Die vorliegende Erfindung betrifft eine Anschlussklemme zum Anpressen eines elektrischen Leiters gegen eine Schiene, mit einem zum Aufsetzen mittels Haltefüssen auf eine Schiene vorgesehenen bügelförmigen Grundkörper und einer an einem im Bügeljoch zwischen den Bügelschenkeln verschieblich gehaltenen Führungsbolzen vorgesehenen Druckplatte, welche unter dem Einfluss einer Druckfeder in Richtung der Schenkelenden gedrückt wird.The present invention relates to a connection terminal for Pressing an electrical conductor against a rail, with one to put on with holding feet provided on a rail bow-shaped base body and one on one in the temple yoke between the temple legs slidably provided guide pin Pressure plate, which under the influence of a compression spring in Direction of the leg ends is pressed.

Die bekannten Klemmen dieser Art, eingesetzt als sog. Schirmanschlussklemmen zum Erden der Abschirmung von abgeschirmten Kabeln, haben den Nachteil, dass sie oft nur mit grösserem Kraftaufwand und relativ umständlich auf eine Schiene aufzusetzen sind.The known clamps of this type, used as so-called. Shield connection clamps for grounding the shielding of shielded Cables have the disadvantage that they are often only with greater effort and relatively cumbersome on a rail are to be put on.

Aufgabe der vorliegenden Erfindung war es somit, eine einfach aufgebaute Anschlussklemme zu konstruieren, welche neben dem eigentlichen Zweck, d.h. dem Anpressen eines Leiters an eine Sammelschiene, auch besonders bedienerfreundlich auf die Schiene aufsetzbar ist.The object of the present invention was therefore a simple to construct the built-in terminal block, which is next to the actual purpose, i.e. pressing a conductor against one Busbar, also particularly user-friendly on the Rail is attachable.

Diese Aufgabe wird bei einer Anschlussklemme der eingangs definierten Art erfindungsgemäss mit den Merkmalen gemäss dem kennzeichnenden Teil von Anspruch 1 auf verblüffend einfache Weise gelöst. This task is carried out at the input terminal defined type according to the invention with the features according to characteristic part of claim 1 to amazingly simple Way solved.

Besondere Ausführungsformen des Erfindungsgegenstandes sind in den abhängigen Ansprüchen definiert.Particular embodiments of the subject matter of the invention are in the dependent claims.

Die Erfindung wird nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen noch etwas näher erläutert. Es zeigen:

Fig. 1 der Zeichnung zeigt in perspektivischer Darstellung eine Schirmanschlussklemme 1 aus Aluminium, welche zum Anpressen eines elektrischen Leiters 2 an eine Sammelschiene 3 dient. Letztere ist z.B. mit der Erdungsanlage verbunden.Fig. 1 of the drawing shows a perspective view Shield connection clamp 1 made of aluminum, which can be pressed on an electrical conductor 2 to a busbar 3. The latter is e.g. connected to the earthing system.

Die Anschlussklemme 1 weist einen bügelförmigen Grundkörper 4 auf, wobei die Bügelschenkel 4', 4" Haltefüsse bilden, um die Klemme 1 auf eine Schiene 3 aufzusetzen. Im Bügeljoch 4"' ist ein Führungsbolzen 5 gehalten, welcher zwischen den Bügelschenkeln 4', 4" verschieblich ist. Am unteren Ende des Führungsbolzens 5 ist eine Druckplatte 6 angeordnet. Zwischen Druckplatte 6 und Bügeljoch 4"' ist eine Druckfeder 7 angeordnet, welche die am Bolzen 5 geführte Druckplatte 6 nach unten drückt und somit bei auf eine Schiene 3 aufgesetzter Klemme 1 den Leiter 2 gegen die Schiene 3 anpresst.The connection terminal 1 has a bow-shaped base body 4 on, the stirrup legs 4 ', 4 "forming support feet to the Place clamp 1 on a rail 3. In the yoke 4 "'is a guide pin 5 held between the stirrup legs 4 ', 4 ". At the lower end of the Guide pin 5, a pressure plate 6 is arranged. Between Pressure plate 6 and yoke 4 "'a compression spring 7 is arranged, which the pressure plate 6 guided on the bolt 5 after presses down and thus when placed on a rail 3 Terminal 1 presses conductor 2 against rail 3.

Die beiden Bügelschenkel 4', 4" weisen jeweils auf der selben Seite in der Schenkelkante 8 bzw. 9 eine Aussparung 10 bzw. 11 auf, welche am unteren Ende des entsprechenden Schenkels durch einen Haltefinger 12 bzw. 13 mit nach oben ragender Endklaue 12' bzw. 13' begrenzt sind.The two bracket legs 4 ', 4 "each point to the same Side in the leg edge 8 or 9 a recess 10 or 11 on which at the lower end of the corresponding leg a holding finger 12 or 13 with an upward claw 12 'and 13' are limited.

Dank dieser Konstruktion lässt sich die Klemme 1 von der Seite her auf die Schiene 3 aufsetzen, wobei die Druckplatte 6 gegen die Kraft der Druckfeder 7 nach oben ausweichen kann, dabei aber den Leiter 2 gegen die Schiene 3 anpresst.Thanks to this construction, clamp 1 can be moved from the side forth on the rail 3, the pressure plate 6 against the force of the compression spring 7 can deflect upwards but presses the conductor 2 against the rail 3.

Die Fig. 2-4 zeigen die Klemme in Frontansicht, von der Seite bzw. in Draufsicht.2-4 show the clamp in front view, from the side or in top view.
