Abstract

The screw (5) clamp for insulated and stripped electric conductors comprises teeth (1A) for cutting through conductor insulation. The teeth are so formed, at least at contact point (1) for conductor to be connected, that the cut insulation is taken-up between the teeth. The clamp consists of two frames, inserted into each other. One is rigidly fitted to electric apparatus and the second, movable, box-shaped frame contains on its top side screw thread for clamping screw, by which the frames are mutually fixed.

Description

Die Erfindung betrifft eine Schraubklemme zum Klemmen von isolierten und abisolierten elektrischen Leitern. The invention relates to a screw terminal for clamping insulated and stripped electrical conductors.

Aufgabe der Erfindung ist, bereits bekannte Ausführungen von Schraubklemmen, in der nur abisolierte Leiter geklemmt werden können, mit einfachen Mitteln so zu verbessern, daß sowohl abisolierte Leiter als auch isolierte Leiter geklemmt werden können. The object of the invention is already known designs of screw terminals in the stripped conductors can be clamped with simple means so that both stripped conductors and insulated conductors can be clamped.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. This object is achieved by the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Ausführungsbeispiele der Erfindung werden anhand der Zeichnungen erläutert. Embodiments of the invention are explained with reference to the drawings.

Es zeigt: It shows:

Fig. 1A eine Schraubklemme nach Anspruch 1, bei der die Kontaktauflagestelle direkt an der in der Seitenansicht dargestellten Geräteanschlußschiene ausgebildet ist. Fig. 1A is a screw terminal according to claim 1, wherein the contact support point is formed directly on the embodiment shown in the side view of device connection rail.

Fig. 1B eine Kastenklemme im Schnitt, die auf die Geräteanschlußschiene nach Fig. 1 aufgeschoben wird. Fig. 1B is a box terminal in section, which is pushed onto the device connection rail according to Fig. 1.

Fig. 2A eine Schraubklemme nach Anspruch 2. Fig. 2A is a screw terminal according to claim 2.

Fig. 2B die Bodenansicht auf den Rahmen 3 der Schraubklemme nach Fig. 2A. Fig. 2B, the bottom view of the frame 3 of the screw terminal according to Fig. 2A.

Fig. 2C die Bodenansicht auf den Rahmen 2 der Schraubklemme nach Fig. 2A, mit abgeschnittenem Boden des Rahmens 3. FIG. 2C, the bottom view of the frame 2 of the screw according to FIG. 2A, with cut off the bottom of the frame 3.

Fig. 2D die Schraubklemme nach Fig. 2A im Schnitt. FIG. 2D, the screw according to FIG. 2A in section.

Fig. 2E die Ansicht auf die Leiterauflageseite des aufgeschnittenen Rahmens 3. FIG. 2E, the view on the circuit bearing side of the cut frame 3.

Fig. 3 eine Klemmenleiste nach Anspruch 6, mit durch einen Räumvorgang erzeugten Zähnen. Fig. 3 is a terminal block according to claim 6, with teeth generated by a broaching process.

An der Schraubklemme zum Klemmen von isolierten und abisolierten elektrischen Leitern sind mindestens an der Kontaktauflagestelle 1 für den anzuschließenden Leiter 3 Zähne 1A zum Durchdringen der Leiterisolierung 3A so ausgeformt, daß die Leiterisolierung 3A durchschnitten und die dabei verdrängte Leiterisolierung 3A zwischen den Zähnen 1A aufgenommen wird. At the screw terminal for clamping insulated and stripped electrical conductors, at least at contact contact point 1 for the conductor to be connected, 3 teeth 1 A are formed for penetrating the conductor insulation 3 A in such a way that the conductor insulation 3 A intersects and the conductor insulation 3 A displaced thereby between the teeth 1 A is recorded.

Vorteilhafterweise sind auch Zähne an der auf die Kontaktauflagestelle 1 aufsteckbaren Kastenklemme angeformt, um die Leiterisolierung 3A in deren Auflagebereich zu durchtrennen und damit eine einwandfreie Kraftübertragung zu bewirken. Advantageously, teeth are also integrally formed on the box terminal that can be plugged onto the contact support point 1 in order to cut through the conductor insulation 3 A in its contact area and thus to achieve a perfect power transmission.

Eine weitere bekannte Schraubklemme zum Klemmen von abisolierten elektrischen Leitern besteht aus zwei ineinandergefügten kastenförmigen Rahmen 2; 3. Der Rahmen 2 ist starr an dem elektrischen Gerät angeordnet und der zweite bewegliche kastenförmige Rahmen 3 ist an seiner Oberseite mit einem Schraubengewinde 3B für die Klemmschraube 5 versehen. Die Klemmschraube 5 ist durch das an der Oberseite des starren Rahmen 2 angeordneten Loch 2B gesteckt ist und liegt dort mit dem Schraubenkopf auf. Alternativ dazu kann auch das Schraubenschaftende der Klemmschraube 5 gegen die Bodeninnenseite des Rahmens 2 wirken um die erforderliche mechanische Verspannung zwischen den beiden Rahmen zu bewirken. Another known screw terminal for clamping stripped electrical conductors consists of two interlocking box-shaped frames 2 ; 3rd The frame 2 is rigidly arranged on the electrical device and the second movable box-shaped frame 3 is provided on its upper side with a screw thread 3 B for the clamping screw 5 . The clamping screw 5 is inserted through the hole 2 B arranged on the top of the rigid frame 2 and rests there with the screw head. As an alternative to this, the screw shaft end of the clamping screw 5 can also act against the inside of the frame 2 in order to bring about the required mechanical bracing between the two frames.

Um zugleich abisolierte und isolierte Leiter klemmen zu können, wird erfindungsgemäß vorgeschlagen, an der unteren Außenseite des ersten starren angeordneten kastenförmigen Rahmen 2 und an der unteren Innenseite des zweiten beweglichen kastenförmigen Rahmen 3, zwischen denen die anzuschließenden Leiter 4 eingelegt werden, Zähne 2A; 3A zum Durchdringen der Leiterisolierung 4A anzuformen. Auch hier gilt, aus Sicherheitsgründen auf beiden Seiten die Leiterisolierung 4A zu durchdringen. To simultaneously stripped and can clamp insulated conductors, the invention proposes, between which the conductor to be connected 4 are placed on the lower outer side of the first rigid arranged box-shaped frame 2 and at the lower inside of the second movable box-shaped frame 3, the teeth 2 A; Form 3 A to penetrate the 4 A conductor insulation. Here too, for safety reasons, the 4 A conductor insulation must be penetrated on both sides.

Kostengünstig sind die Zähne 1A, 2A und 3A bei der Herstellung in einem Prägevorgang auszuformen. The 1 A, 2 A and 3 A teeth can be formed inexpensively in one stamping process during manufacture.

Vorzugsweise sind die Zähne 1A, 2A und 3A in zwei Reihen anzuordnen, wobei die Zahnreihen zueinander um den halben Zahnabstand versetzt werden. Preferably, the teeth 1 A, 2 A and 3 A in two rows are to be arranged, wherein the rows of teeth are offset from each other by half the tooth pitch.

Die Zähne 1A, 2A und 3A sind so zu bemessen, daß die verdrängte Leiterisolierung 4A zwischen den Zähnen 1A, 2A und 3A aufgenommen wird. The teeth 1 A, 2 A and 3 A are to be dimensioned such that the displaced conductor insulation 4 A is accommodated between the teeth 1 A, 2 A and 3 A.

Die Ausgestaltung der Schraubklemme bewirkt auch, daß mehrere nebeneinander angeordnete Leiter 3 gleichen Querschnitts geklemmt werden können. The design of the screw terminal also means that several conductors 3 of the same cross section arranged next to one another can be clamped.

An einer Schraubklemme, die als einzelne Buchsenklemme oder in Form einer Klemmenleiste mit mehreren Klemmstellen ausgebildet ist, können die Zähne 1A durch einen Räumvorgang oder durch Gewindeschneiden erzeugt werden. Die Leiterisolierung 4A wird auch an der den Zähnen gegenüberliegenden Seite durch das Klemmschraubenschaftende durchtrennt. Bezugszeichenliste 1 Kontaktauflagestelle
