Description

Ein allgemein beklagter Übelstand bei dien bisher bekannten Ausfiihrungsarten von Verbinduiigsklemmen für 'elektrische Leitungen ist der, daß die Kontaktsohrauben beim Anschließen der Leitungsdrähte sehr leicht zu weit zurückgeschraubt werden können, so daß sie herausfallen und verlorengehen.A generally lamented malady at dien previously known types of connection terminals for 'electrical cables is that the Kontaktsohrauben when connecting the lead wires can very easily be screwed back too far so that they fall out and get lost.

Dieser Naclitedl wird durch, die Erfindung auf einfachie Weise beseitigt. Zu diesem ίο Zweck wird 'ein Streifen aus Blech vorgesehen, welcher einen Längsschlitz oder zwei Löcher besitzt, die ein HindiuDrcMuihrien der beiden Konfaktschraufoen gestatten. Nach außen setzt sich der Längsschlitz oder die beiden Löcher in engere Schlitze fort, deren Breite den Duxchmessiern der hintesrdrehtein Schäfte der Kiontaktsichraubien entsprechen· Der eigentliche Klemmienkörper besitzt in der •Mtte oben, quer zu seinem Profil, eine Vertäefung. Bieim Zusammensetzen der Klemme wird die Blechbeüage zugleich mit dem Klemmenkörper in ein Isioliergiehäusie eingeschoben und dann die beiden Kontoktschrauben eingezogen. Hierauf wird vermittels eines Hilfs- «5 Werkzeuges, welches man in ein oben angebrachtes Loch des Isoliergehäuses einführt^ die Blechbeüagie in die Vertiefung des Klem-■menkörpers hineingiedrückt, so· daß die Beilage eine Vjerküirzuing erfährt, welqhe zur Folge hat, daß die engeren schlitzartigen Fortsetzungen des Längsschlitzes bzw. dar beiden Löcher der Beüage die beiden Komtaktschrauben an ihnen zwischen Gewinldeschaft und Kopf vorgesehenen Hinterdröhungen umfassen, so daß beim Zurückdrehen der Schrauben diese mit der Bleahbeilage zusammen an der oberen Wand des Gehäuses eine feste Gegenlage finden und ein Entfernen der Schrauben unmöglich machen.This naclitedl is made by that invention eliminated in a simple way. For this purpose, a strip of sheet metal is provided, which has a longitudinal slot or two holes that form a HindiuDrcMuihrien Allow both Konaktschraufoen. To outside the longitudinal slot or the two holes continues into narrower slots, their Spread the knives in the back Shafts of the Kiontaktsichraubien correspond The actual terminal body has in the • Matt a panel at the top, at right angles to his profile. When assembling the clamp, the sheet metal bracket is at the same time as the clamp body inserted into an insulating housing and then pulled in the two account screws. This is followed by means of an auxiliary «5 tool, which is inserted into a hole in the insulating housing at the top ^ the Blechbeüagie in the recess of the clamp ■ body pressed in, so · that the supplement experiences a Vjerküirzuing, welqhe zur The result is that the narrower slot-like continuations of the longitudinal slot or both Holes of the attachment the two compact screws on them between the threaded shaft and Include the back drumming provided for the head, so that when you turn back the screws, they come together with the blade insert Find a fixed counter support on the top wall of the housing and remove the Making screws impossible.

■ In der Zeichnung ist die neue Klemme in beispielsweiser Ausführung in Abb. 1 im Längsschnitt, jedoch mit noch nicht durchgedrückter Beilage, dargestellt. Abb. 2 zeigt dieselbe Klemme im Längsschnitt mit durchgedrückter, also verkürzter Beilage, und zu- +5 rückgezogenen Schrauben. Abb. 3 zeigt die Klemme im Querschnitt und Abb. 4 die gestreckte Beilage von oben. Der Klemmenfcörper ist mit'«, bezeichnet und besitzt die Vertiefung b. Die Blechbeilage ist c, durch welche die Kontaktachraubenrf hindurchgeführt werden. Das IsoMergehäusee besitzt das Hilfsloch/.■ In the drawing, the new clamp is shown as an example in Fig. 1 in a longitudinal section, but with the insert not yet pushed through. Fig. 2 shows the same clamp in a longitudinal section with the insert pushed through, i.e. shortened, and the screws +5 withdrawn. Fig. 3 shows the clamp in cross section and Fig. 4 shows the stretched insert from above. The clamp body is marked with '«and has the recess b. The sheet metal insert is c, through which the contact screwsrf are passed. The IsoMer housing e has the auxiliary hole /.
