Description

Schraubenschlitzklemme für mehradrige elektrische Leitungen Zusatz zum Patent 680 496 Die Erfindung bezieht sich auf eine Schraubenschlitzklemnze für mehradrige elektrische Leitungen mit Schraubkappe und einem unter der Wirkung eines Federrings stehenden, im Zwischenraum der Klemmenfußschenkel liegenden, mit Spiel .eingesetzten, T-förmigen Druckstück nach Patent 680 496 sowie einem in der Schraubkappe beweglich gelagerten Druckstück.Screw slot terminal for multi-core electrical cables Addendum to patent 680 496 The invention relates to a screw slot terminal for multi-core electrical cables with a screw cap and a T-shaped pressure piece according to patent 680, which is under the action of a spring ring and located in the space between the terminal foot legs and is inserted with play 496 as well as a pressure piece movably mounted in the screw cap.

Bei dieser Einrichtung nach dem Hauptpatent tritt beim Einspannen des Leiters ein Drehmoment auf, das sich vom Federring dem T-förmigen Druckstück mitteilt mit der Folge, daß dasselbe von seiner lotrechten Lagestellung aus in eine Schräglage versetzt wird, wodurch sich das eine freie Ende des T-Balkens des Druckstückes in den einzuklemmenden Leiter eingräbt.In this device according to the main patent occurs when clamping of the conductor to a torque, which is from the spring ring to the T-shaped pressure piece communicates with the result that the same from its vertical position in a Inclined position is offset, whereby the one free end of the T-bar of the pressure piece digs into the conductor to be clamped.

Die zusätzliche Erfindung bringt nun eine Erweiterung dieser Anklemmwirkung insofern, ,als sie sich jetzt nicht nur von oben, sondern auch - außerdem von unten her erstreckt. Es ist der aus einem kurzen, runden Zapfen bestehende Steg eines solchen T-förmigen Druckstückes in einer entsprechenden Bohrung des Klemmenfußes gelagert, und es steht .dieses Druckstück unter der Wirkung zweier verschieden großer Federringe, von denen der größere gegen den Flansch und der kleinere gegen die Grundfläche des zapfenförmigen Steges des T-förmigen Druckstückes drücken.The additional invention now brings an expansion of this clamping effect insofar as they are now not only from above, but also - also from below extends forward. It is the bridge of a short, round cone such T-shaped pressure piece in a corresponding bore of the clamp foot stored, and this pressure piece is under the action of two different sizes Spring washers, the larger of which against the flange and the smaller against the base of the peg-shaped web of the T-shaped pressure piece.

Der einzuklemmende Leiter wird danach sowohl von oben als auch von unten von Druckstücken beein$ußt, die bei einem bestimmten Grad der Einklemmung einer Knickwirkung unterliegen, so daß beide Druckstücke nicht mehr lotrecht übereinanderliegen, sondern einen stumpfen Winkel miteinander bilden.The conductor to be clamped is then both from above and from at the bottom influenced by pressure pieces, which at a certain degree of entrapment are subject to a buckling effect, so that both pressure pieces are no longer perpendicular to each other, but rather form an obtuse angle with one another.

In der Zeichnung ist ein Ausführungsbeispiel einer Einrichtung nach der Erfindung dargestellt. Es :zeigen die Abb. i und 2 Längsschnitte durch die Schraubenschlitzklemme, die Abb. 3 und q: Einzelheiten und die Abb.5 den Schnitt nach der Linie A-B der Abb.. i. Schließlich zeigt Abb. 6 die Wirkungsweise der Klemme. Die Schraubenschlitzklemme besteht aus der Schraubkappea; dem geschlitzten Unterteil b und den Druckstücken c und d, zwischen denen der elektrische Leiter i festgeklemmt wird.In the drawing, an embodiment of a device according to the invention is shown. It: Fig. I and 2 show longitudinal sections through the screw slot clamp, Fig. 3 and q: Details and Fig.5 the section along the line AB in Fig. I. Finally, Fig. 6 shows how the clamp works. The screw slot terminal consists of the screw capa; the slotted lower part b and the pressure pieces c and d, between which the electrical conductor i is clamped.

Der' auf die Scheibe,e übertragene Pneßdruck der überwurfmuttera spannt die Federringe f und f l, -und zwar so; daß das untere Druckstück d durch die Feder f 1, die gegen die Unterseite des Zapfens k sich anlegt, zunächst etwas angehoben wird und es sich dann zusammen mit dem Druckstück c im Sinne der Abb.6 so schräg legt, daß sich zwei gegenüberliegende ,äußere Enden der beiden Druckstücke in den Leiter eingraben.The 'on the disc, e transferred pneumatic pressure of the union nut tensions the spring washers f and f l, -and so; that the lower pressure piece d is initially raised slightly by the spring f 1, which rests against the underside of the pin k, and then together with the pressure piece c in the sense of Fig. 6 it is so inclined that two opposite, outer ones Dig the ends of the two pressure pads into the conductor.
