Description
Vorrichtung zum Anschliessen und Befestigen von elektrischen Kabeln, insbesondere von Hochspannungskabeln. Die Erfindung hat eine Vorrichtung zum Anschliessen und Befestigen von elektrischen Kabeln, insbesondere von Hochspannungs kabeln mit einer zylindrischen Öffnung und einer zentral darin angeordneten Anschluss- elektrode zum Gegenstand. Bei derartigen Kabelverbindungen ist es von Wichtigkeit, dass ein guter elektrischer Kontakt gewähr leistet und dass das Kabel so befestigt ist, dass es auch auf Zug beansprucht werden kann.
Gemäss der Erfindung wird dies durch ein Gewinde in der Öffnung erreicht, welches sich beim Einführen des Kabels in die Ka belisolation eingräbt und durch ein Gewinde auf der Elektrode, welches beim Einführen des Kabels in die Kabelseele eingeschraubt wird. Infolge des in die Kabelisolation ein geschraubten Gewindes kann die Verbindung einen Zug am Kabel aufnehmen und durch die in die Kabelseele eingeschraubte An- schlusselektrode ist ein guter elektrischer Kontakt hergestellt.
In der Abbildung ist als Ausführungs beispiel des Erfindungsgegenstandes ein Zünd kerzenstecker mit eingeschraubtem Zünd kerzenanschlusskabel im Schnitt dargestellt. Der Stecker besteht aus einem Gehäuseteil a aus Isolierstoff, z. B. aus Bakelit, in wel chen ein Steckkontakt b, vorzugsweise aus Messing, eingelassen ist, der auf eine Zünd kerze aufgesteckt werden kann. Der Steck kontakt b bildet in der Öffnung c des Ge häuseteils a eine Schraube<I>d</I> mit Holzschrau bengewinde, welche die Anseblusselektrode für ein Zündkerzenanschlusskabel e darstellt.
Beim Einführen des Kabels e in die mit einem Kordelgewinde f versehene Öffnung c durch Verdrehen des Kabels e gräbt sich das Kordelgewinde f in die Isolation des Kabels e und das Holzschraubengewinde der An schlusselektrode d in die' Kabelseele e' des Kabels e ein. Damit der Vorschub des Ka bels e in der Öffnung c gleich dem Vor schub der Schraube d in der Kabelseele e' ist, haben das Nordelgewinde f in der Öff- nung c und das Holzschraubengewinde der Schraube d zweckmässig dieselbe Steigung.
Ein auf diese Weise hergestellter Kabel anschluss ist in hohem Masse zugsicher und stellt gleichzeitig eine elektrisch gutleitende Verbindung her.
Device for connecting and securing electrical cables, in particular high-voltage cables. The subject of the invention is a device for connecting and securing electrical cables, in particular high-voltage cables with a cylindrical opening and a connecting electrode arranged centrally therein. With such cable connections, it is important that good electrical contact is ensured and that the cable is attached in such a way that it can also be subjected to tensile stress.
According to the invention, this is achieved by a thread in the opening, which digs into the cable insulation when the cable is inserted, and by a thread on the electrode which is screwed into the cable core when the cable is inserted. As a result of the thread screwed into the cable insulation, the connection can absorb a pull on the cable, and the connection electrode screwed into the cable core creates a good electrical contact.
In the figure, a spark plug connector with a screwed-in spark plug connection cable is shown in section as an embodiment of the subject matter of the invention. The plug consists of a housing part a made of insulating material, for. B. Bakelite, in wel chen a plug contact b, preferably made of brass, is let in, which can be plugged onto a spark plug. The plug contact b forms in the opening c of the housing part a a screw <I> d </I> with wood screw thread, which represents the connection electrode for a spark plug connection cable e.
When the cable e is inserted into the opening c provided with a cord thread f by twisting the cable e, the cord thread f digs into the insulation of the cable e and the wood screw thread of the connection electrode d digs into the 'cable core e' of the cable e. So that the advance of the cable e in the opening c is equal to the advance of the screw d in the cable core e ', the Nordel thread f in the opening c and the wood screw thread of the screw d expediently have the same pitch.
A cable connection made in this way is highly tensile and at the same time creates an electrically conductive connection.
