Description

Verfahren zur Herstellung einer Verbindungsklemme für elektrische Leitungen mit unverlierbaren Teilen Zusatz zum Patent 462 663 Die Bauart der Verbindungsklemme für elektrische Leitungen nach Patent q.6- 66,3 hat den Nachteil, daß beim gewaltsamen Zurückdrehen der Klemmschraubend die Blechbeilagen c durchgedrückt und die Klemmschraubend entfernt werden können.A process for producing a connecting terminal for electrical cables with captive parts additive to Patent 462 663 The structure of the connecting terminal for electrical cables according to q.6- 66.3 has the disadvantage that during the forcible reverse rotation of the clamping screwing c sheet metal inserts pressed and the clamping screwing removed can be.

Durch die Erfindung soll dieser Übelstand beseitigt werden, und zwar geschieht dies dadurch, daß an Stelle der gemeinsamen Blechbeilage c für die beiden Klemmschraubend für jede Schraube eine besondere Blechbeilage verwendet wird. Von diesen Blechbeilagen besitzt jede ein Durchgangsloch für die Klemmschraube, dessen Rand zum Zweck der Vergrößerung des Lochdurchmessers hochgezogen ist. Beim erstmaligen Anziehen der Klemmschraube wird dieser Lochrand niedergedrückt, wodurch sich sein Durchmesser verkleinert und so den hinterdrehten Schaft der Klemmschraube umfaßt. Beim Zurückdrehen der Schraube hebt sich die Blechbeilage mit und verhindert durch ihr Anstoßen an der oberen Wand des Isoliergehäuses das Herausfallen der Schraube. Dadurch, daß die Klemmschrauben an ihren unteren Enden gewindefreie Zapfen besitzen, drehen sich dieselben beim Zurückschrauben in dem Augenblick, in dem sie das Muttergewinde verlassen, vollkommen leer, und sind dadurch auch die Blechbeilagen von dem vertikalen Druck der Schrauben entlastet. Gleichzeitig verhindern die gewindefreien Zapfen das Herausfallen der Klemmenkörper aus dem Isoliergehäuse.The invention is intended to eliminate this drawback, namely this is done by the fact that instead of the common sheet metal insert c for the two Clamping screw a special sheet metal shim is used for each screw. from these sheet metal shims each has a through hole for the clamping screw, its Edge is pulled up for the purpose of enlarging the hole diameter. At the first time Tightening the clamping screw will depress this edge of the hole, causing it to be Reduced diameter and thus includes the undercut shaft of the clamping screw. When the screw is turned back, the sheet metal shim lifts with it and prevents it through Their impact on the upper wall of the insulating housing causes the screw to fall out. Because the clamping screws have thread-free pins at their lower ends, when they are screwed back, they turn at the moment when they open the nut thread abandoned, completely empty, and are therefore also the sheet metal inserts from the vertical one Pressure on the screws is relieved. At the same time, the thread-free tenons prevent the terminal body falling out of the insulating housing.

In der Zeichnung ist die Klemme in beispielsweiser Ausführung in Abb. i im Längsschnitt mit einer noch nicht niedergeschraubten und einer zurückgeschraubten Klemmschraube, in Abb.2 in der Seitenansicht mit vollständig niedergeschraubter Klemmschraube und in Abb. 3 in der Aufsicht dargestellt.In the drawing, the clamp is shown as an example in Fig. i in longitudinal section with one not yet screwed down and one screwed back Clamping screw, in Fig. 2 in the side view with fully screwed down Clamping screw and shown in Fig. 3 in plan view.

a ist der KlemmenkÖrper, c sind die Blechbeilagen und d die hinterdrehten Klemmschrauben mit dem gewindefreien Zapfen f. Das Ganze ist in das Isoliergehäuse e eingebaut.a is the clamp body, c is the sheet metal shims and d is the back-turned Clamping screws with the thread-free pin f. The whole thing is in the insulating housing e built in.
