Description

In Schaltanlagen werden zur Verbindung von Leitungen sog:- Reihenklemmen od. @dgl. verwendet, die der Reihe nach nebeneinander auf einer gemeinsamen Tragschiene befestigt werden, Für die Montage und die Wartung der Anlage ist es hierbei günstig, wenn. die Reihenklemmen in @d'er Tragschiene leicht befestigt und ebenso leicht, voir allem ohne Lösung vom Befestigungsgliedern, wieder abgenommen bzw. ausgewechselt werden können. Zur Befestigung von Reihenklemmen in Profilschienen sind bereits federnde Elemente bekanntgeworden, die .die Verriegelung des Körpers nach dein Einsetzen vollziehen. Bekannte Anordnungen verwehden eine Kugel oder einen dachartigen, unisymmetrisch abgeflachten Zylinder, die unter d'em Druck einer Feder stehen. Die Feder wird hierbei einseitig in den Isolierkörper eingesetzt. Der Nachteil dieser bekannten Anordnung liegt .darin, daß der Querschnitt in der Befestigungsebene wesentlich geschwächt wird- und insbesondere beim Lösen der Reihenklemmen aus der Schiene ein verhältnismäßig großer Hebelarm durch die U-förmige Fassung der Feder entsteht und damit der restliche Querschnitt stark beansprucht wird.In switchgear, so-called: - Terminal blocks are used to connect lines or @dgl. used, one after the other, one after the other on a common mounting rail For the assembly and maintenance of the system, it is advantageous here to if. the terminal blocks are easily attached to the mounting rail and just as light, voir all without loosening the fastening members, removed again or replaced can be. There are already resilient elements have become known, the .the locking of the body after your insertion carry out. Known arrangements twist a ball or a roof-like, unisymmetrical flattened cylinders that are under the pressure of a spring. The spring is here Inserted into the insulator on one side. The disadvantage of this known arrangement lies .darin that the cross-section is significantly weakened in the mounting plane becomes - and especially when releasing the terminal blocks from the rail a relatively large lever arm is created by the U-shaped version of the spring and thus the rest Cross-section is heavily used.

Die Erfindung hat die Aufgabe, die Befestigung der Reihenklemmenkörper oid. dgl. an einer Tragschiene mittels eines federnden Elementes zu verbessern, insbesondere den am meisten beanspruchten Onerschnitt zu verstärken bzw. die Beanspruchung zu verteilen.. Erfindungsgemäß werden Reihenklemmenkörper an einer Tragschiene durch einen unter Federdruck stehenden Doppelriegel, der an. den, in die Tragschiene einsgreifenden Enden mit dem Tragschienenprofil angepaßten Aussparungen versehen ist, befestigt. Damit kann der in. die Tragschienen eingreifende Teil des. ReihenklemmenköTpers -wesentlich fester ausgebildet werden. Durch die Anordnung der Feder in einem Durchbruch bleibt ein geschlossener Ring erhalten, sot daß auch beim Lösen der Reihenklemmen keine großen Hebelkräfte auftreten, können.The invention has the task of securing the terminal block body oid. the like. to improve on a mounting rail by means of a resilient element, in particular to reinforce the most stressed single section or the stress to distribute .. According to the invention, terminal blocks are attached to a mounting rail a spring-loaded double bolt that is on. the one engaging in the mounting rail Ends is provided with cutouts adapted to the mounting rail profile, fastened. In this way, the part of the terminal block body that engages in the mounting rails - are made much more solid. By arranging the spring in an opening a closed ring remains, so that also when loosening the terminal blocks no great leverage can occur.

An Hand der Zeichnung wird ein Ausführungsbeispiel eines Doppelriegels nach der Erfindung näher erläutert.An exemplary embodiment of a double bolt is shown on the basis of the drawing explained in more detail according to the invention.

In den, Fi;g. i und 2 ist der Reihenklemmenkörper i in der Tragschiene 2 befestigt. Der, in Fig. 3 nochmals gesondert dargestellte Doppelriegel 3 greift mit dem Ausschnitt ¢ in den einenWinkelarm der Tragschiene ein, der andere Arm der Tragschiene greift in bekannter Weise in eine Aussparung 5 des Isolierkörpers i ein. In: dem Durchbruch 6 im Fuß des Isolierkörpers i ist die Feder 7 angeordnet, die auf den die beiden Plattenriegel starr verbindenden Arm 8 drückt. Zur besseren Führung können die beiden Plattenriegel 3a und! 3b in Aussparungen 9a und 9b geführt werden, womit eine sichere Halterung erzielt wird. Im Gegensatz zu den bekannten Klemmen wird beim Lösen der Klemme aus der Tragschiene nicht nur der Querschnitt io, sondern auch der Querschnitt ii beansprucht. Ein Abbrechen des, die Feder tragenden Arms 12, der bei den bekannten Anordnungen nur durch den Querschnitt io gehalten wird, ist hier nicht möglich.In the, Fi; g. i and 2 is the terminal block body i in the mounting rail 2 attached. The double bolt 3, shown separately again in FIG. 3, engages with the cut-out ¢ into one angle arm of the mounting rail, the other arm of the Support rail engages in a known manner in a recess 5 of the insulating body i a. In: the opening 6 in the foot of the insulating body i, the spring 7 is arranged, which presses on the arm 8 rigidly connecting the two plate bars. For better The two plate bars 3a and! 3b out in recesses 9a and 9b with which a secure mounting is achieved. In contrast to the known When the clamp is released from the mounting rail, it is not just the cross-section that becomes clamped io, but also the cross-section ii claimed. A breaking off of that which carries the spring Arms 12, held in the known arrangements only by the cross section io is not possible here.

Ein weiterer Vorteil der Anordnung nach der Erfindung wird noch dadurch erreicht, daß@ durch die plattenförmige Ausbildung des, Doppelriegels die Feder inZusammenwirken mit dem Iso@lierkö@rperfuß von der Umgebung vollkommen abgeschlossen wird und somit die Verschmutzung des Federraums und der Feder stark eingeschränkt wird.Another advantage of the arrangement according to the invention is still thereby achieved that @ through the plate-shaped design of the double bar, the spring In cooperation with the insulating body foot, it is completely closed off from the environment and thus the contamination of the spring chamber and the spring is severely restricted will.
