Abstract

The connecting terminal is used for connecting electrical systems and cables. It consists of a cylindrical part (1) with an axial threaded hole (3) for screwing the terminal onto a connecting bolt on the system side and of a tab part (2) with a central hole (6) for holding a mounting screw for cable terminals.

Description

Die Erfindung betrifft eine Anschlupklemme zur Verbindung elektrischer Anlagen und Kabel.The invention relates to a connection terminal for connecting electrical systems and cables.

Beim Anschließen von Kabeln an elektrische Anlagen, wie Motoren, Trans­formatoren, Kondensatoren oder andere Einrichtungen mit hohem Stromflup, wurden bisher die Kabel mittels Kabelschuhe auf die anlageseitigen, mit einem Gewinde versehenen Anschlußbolzen gesteckt und mit Hilfe einer Messingmutter gegen eine Kontaktfläche des Bolzens gespannt. In den dafür vorgesehenen gebräuchlichen Anschlußgehäusen sind die Anschlußbolzen in relativ kleinen Abständen angeordnet, so daß für größere Kabelquerschnitte nicht genug Montageraum zur Verfügung steht und für sehr hohe Ströme (>100 A) die Kontaktflächen nicht ausreichend groß sind. An den dabei bestehenden Übergangswiderständen können unzulässig starke Erwärmungen auftreten, die häufig zu Betriebsstörungen führen.When connecting cables to electrical systems such as motors, transformers, capacitors or other devices with a high current flow, the cables were previously plugged onto the system-side, threaded connection bolts using cable lugs and clamped against a contact surface of the bolt using a brass nut. The connecting bolts are arranged in relatively small intervals in the customary connection housings intended for this, so that there is not enough installation space available for larger cable cross sections and the contact areas are not sufficiently large for very high currents (> 100 A). Excessively high temperatures can occur at the existing contact resistances, which often lead to malfunctions.

Vorliegender Erfindung liegt die Aufgabe zugrunde, eine Anschlußklemme zu entwickeln, durch die die vorstehend geschilderten Nachteile beseitigt sind.The object of the present invention is to develop a connection terminal by which the disadvantages described above are eliminated.

Die Lösung der Aufgabe besteht darin, daß die Anschlußklemme aus einem zylindrischen Teil mit einer axialen Bohrung, die ein Innengewinde zum Aufschrauben der Klemme auf einen anlageseitigen Anschlußbolzen aufweist, und aus einem sich anschließenden Laschenteil mit einer zentralen Bohrung zur Aufnahme einer Befestigungsschraube für Kabelschuhe besteht.The solution to the problem is that the connecting terminal consists of a cylindrical part with an axial bore, which has an internal thread for screwing the terminal onto a system-side connecting bolt, and of a subsequent tab part with a central bore for receiving a fastening screw for cable lugs.

Weitere Einzelheiten und Vorteile der erfindungsgemäßen Anschlußklemme sind anhand eines in der Zeichnung dargestellten Ausführungsbeispiel nach­folgend beschrieben.Further details and advantages of the terminal according to the invention are described below with reference to an embodiment shown in the drawing.

Die Anschlußklemme ist in der Zeichnung im Längsschnitt dargestellt und besteht in einem Stück aus einem zylindrischen Teil 1 und einem Laschen­teil 2. Der zylindrische Teil weist eine axiale Bohrung 3 auf, die mit einem Innengewinde 4 zum Aufschrauben der Klemme auf einen anlageseitigen Anschlußbolzen versehen ist. Der Laschenteil bietet die Kontaktflächen 5 und nimmt in einer zentralen Bohrung 6 die Befestigungsschraube für eine oder mehrere Kabelschuhe auf.The terminal is shown in the drawing in longitudinal section and consists in one piece of a cylindrical part 1 and a tab part 2. The cylindrical part has an axial bore 3, which is provided with an internal thread 4 for screwing the terminal onto a system-side connecting bolt. The tab part offers the contact surfaces 5 and receives the fastening screw for one or more cable lugs in a central bore 6.

ES ist zweckmäßig, den zylindrischen Teil durch einen achsparallelen Ein­schnitt 7 in zwei Zylinderhälften zu teilen und die eine Hälfte mit Bohrungen 8 und die andere Hälfte mit diesen korrespondierenden Gewinde­bohrungen 9 zu versehen, um mittels Schrauben 10 den Teil 1 gegen Ver­drehen festspannen zu können.It is expedient to divide the cylindrical part into two cylinder halves by an axially parallel incision 7 and to divide one half with To provide holes 8 and the other half with these corresponding threaded holes 9 in order to be able to clamp part 1 against rotation by means of screws 10.

Die neue Anschlußklemme ermöglicht den Anschluß auch mehrerer Kabel auf einem Anschlußbolzen, wobei durch den großflächigen Laschenteil auch für sehr hohe Ströme ausreichend Kontakt gegeben ist. An den Kontaktstellen treten dadurch keine Erwärmungen mehr auf. Ferner sind Berührungen benachbarter Kabelschuhe durch Verdrehen beispielsweise infolge Vibrationen ausgeschlossen.The new connection terminal enables the connection of several cables on one connection bolt, whereby the large area of the lug section provides sufficient contact even for very high currents. As a result, no warming occurs at the contact points. Touches of adjacent cable lugs due to twisting, for example as a result of vibrations, are also excluded.
