Description
Maulklemmen mit starren Klemmkörpern und starren Druckelementen sind für den Anschluß von leicht verformbaren Leitungen an elektrischen Geräten wenig geeignet, weil sich die auf Druck beanspruchten Leitungen bei Erschütterungen oder Temperaturwechsel leicht lockern.Jaw clamps with rigid clamping bodies and rigid pressure elements are little for the connection of easily deformable lines to electrical devices suitable because the lines subject to pressure are exposed to vibrations or Slightly loosen temperature changes.
Es wurde deshalb bereits vorgeschlagen, solche Maulklemmen mit Federeinlagen zu versehen oder die Klemmschrauben in einen mit Gewinde versehenen federnden Klemmbügel einzudrehen. Derartige mehrteilige Klemmen sind jedoch in der Handhabung nicht bequem und in der Herstellung verhältnismäßig teuer.It has therefore already been proposed to use such jaw clamps with spring inserts to provide or the clamping screws in a threaded spring clamp to turn. However, such multi-part clamps are not convenient to use and relatively expensive to manufacture.
Nach der Erfindung besteht die federnde Maulklemme zur Befestigung an elektrischen Geräten aus einem einzigen über seine Länge gleich starken und federnden Blechstreifen, dessen eines Ende im Gerät befestigt ist, dessen Mittelteil doppellagig zusammengebogen und mit dem anderen Ende des Blechstreifens C-förmig zum Klemmenmaul verformt ist. Im doppellagigen Mittelteil befindet sich das Schraubloch für die Klemmschraube, die in das Klemmenmaul hineinragt. Zur Sicherung gegen Herausziehen des in das Gerät eingelegten Endes kann dieses Ende in an sich bekannter Weise entweder mit seitlichen Aussparungen oder Ansätzen, ausgestanzten Lappen, Löchern od. dgl. versehen sein.According to the invention, there is the resilient jaw clamp for attachment on electrical devices from a single one that is equally strong and resilient over its length Sheet metal strip, one end of which is fastened in the device, the middle part of which is double-layered bent together and with the other end of the sheet metal strip C-shaped to the terminal mouth is deformed. The screw hole for the Clamping screw that protrudes into the clamp mouth. To secure against pulling out of the end inserted into the device, this end can either be in a manner known per se with lateral recesses or approaches, punched-out lobes, holes or the like. be provided.
In der Zeichnung sind einige Ausführungsbeispiele der Erfindung dargestellt.Some exemplary embodiments of the invention are shown in the drawing.
Fig. i zeigt einen Schnitt beispielsweise durch zwei abgebrochene Schaltkammerscheiben eines Paketschalters mit einer zwischen diesen befestigten federnden Maulklemme gemäß der Erfindung; Fig. 2 zeigt eine Aufsicht auf die Maulklemme mit seitlichen Aussparungen in dem zwischen den Schaltkammerscheiben liegenden Teil, Fig. 3 eine Aufsicht mit seitlichen Ansätzen für die Halterung der Klemme; Fig. 4 stellt einen Schnitt durch zwei Schaltkammerscheiben und durch eine Maulklemme mit aus der Fläche der Klemme herausgedrücktem Halteansatz dar, Fig. 5 die Aufsicht dieser Klemme; in Fig. 6 ist die Aufsicht einer Klemme mit ausgeschnittenem Halteloch dargestellt.Fig. I shows a section, for example, through two broken switch chamber disks of a package switch with a resilient jaw clamp according to the invention fastened between them; FIG. 2 shows a plan view of the jaw clamp with lateral recesses in the part lying between the switching chamber disks; FIG. 3 shows a plan view with lateral attachments for holding the clamp; FIG. 4 shows a section through two switching chamber disks and through a jaw clamp with the retaining lug pushed out of the surface of the clamp; FIG. 5 shows the top view of this clamp; FIG. 6 shows a top view of a clamp with a retaining hole cut out.
Fig. 7 zeigt die Ansicht einer Klemme mit Längsschlitz für die seitliche Federung eines Kontaktmessers und für die Federung nach oben und unten, Fig. 8 die Aufsicht dieser Klemme; Fig. 9 zeigt eine aus Blech gezogene Profilstange, aus welcher die Klemmen durch Abschneiden hergestellt werden.FIG. 7 shows the view of a clamp with a longitudinal slot for the lateral suspension of a contact blade and for the upward and downward suspension; FIG. 8 shows the top view of this clamp; Fig. 9 shows a profile rod drawn from sheet metal, from which the clamps are made by cutting.
In den Zeichnungen haben die Bezugsziffern folgende Bedeutung: i ist das Ende der Klemme, das zwischen die Schaltkammerscheiben:2 und 3 eines Paketschalters geklemmt ist, 4 ein beliebig gestalteter Anschlußkontakt, 5 das Innere der Schaltkammer, 6 das durch Zusammenbiegen des Bleches entstandene Mittelteil der Klemme, 7 die Klemmschraube, 8 die federnde Auflage für den Leitungsdraht, 9 die Auflagefläche der Klemme auf dem Gerät, io bis 13 Aussparungen, Ansätze und Löcher zur Sicherung des Sitzes und 14 ein Längsschlitz im Teil i der Klemme.In the drawings, the reference numbers have the following meanings: i is the end of the clamp that is clamped between the switching chamber washers: 2 and 3 of a package switch, 4 any connection contact, 5 the interior of the switching chamber, 6 the middle part of the Terminal, 7 the clamping screw, 8 the resilient support for the conductor wire, 9 the contact surface of the terminal on the device, io to 13 recesses, lugs and holes to secure the seat and 14 a longitudinal slot in part i of the terminal.
Die Klemme läßt sich nicht nur für Paketschalter, sondern auch für elektrische Geräte anderer Art verwenden.The terminal can be used not only for parcel switches, but also for use other types of electrical equipment.
