Description

Die vorliegende Erfindung betrifft eine Klemmschraube für Klemmsteine und Klemmdosen oder sonstige Verbindungsmittel elektrischer Leitungen, die mit einem konischen Vierkantloch versehen ist, so daß sie vermittels eines entsprechenden Vierkantdornes eingeschraubt werden kann. Das Wesen der Erfindung besteht darin, daß das Vierkantloch die Klemmschraube in der ganzen Länge durchxo setzt, so daß das Vierkantloch am unteren Ende scharfe Lochkanten aufweist, die sich beim Anziehen der Klemmschraube fest in die Drahtenden eindrücken und infolgedessen einen besseren elektrischen Kontakt zwischen den gegeneinander zu verbindenden Leitungsdrähten gewährleisten.The present invention relates to a clamping screw for terminal blocks and terminal boxes or other connecting means of electrical lines, which is provided with a conical square hole so that they mediate a corresponding square mandrel can be screwed in. The essence of the invention consists in the fact that the square hole runs through the clamping screw along its entire length sets so that the square hole at the lower end has sharp hole edges, which are when Tighten the clamping screw, press it firmly into the wire ends and, as a result, one better electrical contact between the lead wires to be connected to each other guarantee.

Auf der beiliegenden Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes zur Darstellung gebracht worden, und zwar zeigt: ao Abb. ι die Klemmschraube bei ihrer Verwendung in einem sogenannten Klemmstein für Rohrdosen zum Teil in Außenansicht, zum Teil im Schnitt,On the accompanying drawing is an embodiment of the subject invention for Representation has been brought, namely shows: ao Fig. Ι the clamping screw in its use in a so-called terminal block for pipe sockets partly in external view, partly in section,

Abb. 2 in Draufsicht;Fig. 2 in plan view;

as Abb. 3 zeigt die Klemmschraube in Verbindung mit einer Porzellanklemmdose.he fig. 3 shows the clamping screw in connection with a porcelain junction box.

In Abb. ι und 2 des Ausführungsbeispieles bezeichnet α den ringförmigen Klemmstein für eine Rohrdose aus Porzellan, in welchem die vier Klemmkörper δ1, δ2, δ3, δ4 aus Metall gleichmäßig verteilt in entsprechende Vertiefungen eingegipst sind. Das herausragende Ende dieser metallischen Klemmkörper δ1, δ2, δ3, δ4 ist mit Innengewinde c zur Aufnahme der Klemmschraube d und mit einem Längsschlitz e zur Einführung der Leitungsdrähte versehen. Die in das Gewinde c dei Klemmkörper δ1, δ2, δ3, δ4 passenden Klemmschrauben d erhalten in ihrer Längsrichtung ein konisches Vierkantloch f, welches zum Aufstecken der Schrauben auf einen Vierkantdorn dient. Da das Vierkantloch durchgeht, so entstehen am unteren Ende scharfe Lochkanten. Mit diesen drückt die Schraube auf die Drähte, wodurch ein guter Kontakt gewährleistet ist.In Fig. Ι and 2 of the embodiment, α denotes the ring-shaped terminal block for a pipe socket made of porcelain, in which the four clamping bodies δ 1 , δ 2 , δ 3 , δ 4 made of metal are plastered evenly distributed in corresponding depressions. The protruding end of this metallic clamping body δ 1 , δ 2 , δ 3 , δ 4 is provided with an internal thread c for receiving the clamping screw d and with a longitudinal slot e for introducing the lead wires. The clamping screws d that fit into the thread c of the clamping bodies δ 1 , δ 2 , δ 3 , δ 4 have a conical square hole f in their longitudinal direction, which is used to attach the screws to a square mandrel. Since the square hole goes through, sharp hole edges are created at the lower end. With these, the screw presses on the wires, which ensures good contact.

Abb. 3 zeigt die Anordnung der Klemmschrauben in einer üblichen Porzellanklemmdose. Die vier Klemmkörper δ1, δ2, δ3, δ4 sind mit den dazugehörigen Klemmschrauben d in den Boden g des Porzellankörpers der Dose h eingelassen.Fig. 3 shows the arrangement of the clamping screws in a conventional porcelain terminal box. The four clamping bodies δ 1 , δ 2 , δ 3 , δ 4 are let into the bottom g of the porcelain body of the can h with the associated clamping screws d.
