An embodiment of the innovation is shown in the drawing and will be described in more detail below. Show it
Fig. 1
a view of a contact element with a connected conductor,
Fig. 2
the view of the contact element, and
Fig. 3
the view of a ferrule.

In der Fig. 1 ist ein Kontaktelement 1 mit einem angeschlossenen Leiter 2 dargestellt, während die Fig. 2 das Kontaktelement an sich und Fig. 3 die zum Anschluß des Leiters verwendete Klemmhülse 3 zeigt.1 is a contact element 1 with a connected conductor 2 shown, while Fig. 2 the contact element itself and Fig. 3 the used to connect the conductor ferrule 3 shows.

Das Kontaktelement 1 weist ein hier als Stiftkontakt ausgebildetes Kontaktende 4 und ein Leiteranschlußende 5 auf. Das Leiteranschlußende ist als Hülse 6 mit einer axialen Bohrung 7 ausgebildet. Das äußere Ende der Hülse ist mit axialen Schlitzen 8 versehen, so daß dieses Ende radial zusammendrückbar ist. An diesen geschlitzten Bereich schließt sich ein nicht geschlitzter Bereich an. In diesen nicht geschlitzten Bereich ist die Hülse mit einem Außengewinde 9 versehen. Zwischen dem Kontaktende 4 und dem Leiteranschlußende des Kontaktelementes ist ein weiterer Bereich 10 vorgesehen, der mit gegenüberliegenden Abflachungen 11 versehen ist, so daß hier ein Maulschlüssel zum Festhalten des Kontaktelementes beim Leiteranschluß aufsetzbar ist.The contact element 1 has a contact end designed here as a pin contact 4 and a conductor connection end 5. The conductor connection end is as Sleeve 6 formed with an axial bore 7. The outer end of the sleeve is provided with axial slots 8 so that this end can be compressed radially is. A non-slotted area adjoins this slotted area Range. The sleeve is in this non-slotted area provided with an external thread 9. Between the contact end 4 and the A further region 10 is provided for the conductor connection end of the contact element, which is provided with opposite flats 11, so that here an open-end wrench to hold the contact element in place when connecting the conductor is attachable.

Auf die Hülse 6 ist die in der Fig. 3 als Einzelteil dargestellte Klemmhülse 3 aufgeschraubt. Die Klemmhülse ist hierzu mit einem Innengewinde 12 versehen. Weiterhin weist die Klemmhülse einen inneren, verengten Rand 13 auf, der beim Aufschrauben der Klemmhülse auf das Kontaktelement gegen den geschlitzten Bereich der Hülse des Kontaktelementes gedrückt wird und diesen Bereich radial zusammenpreßt. Dabei wird der zuvor in die Hülse eingeführte Leiter festgeklemmt und eine einwandfreie elektrische und mechanische Verbindung zwischen dem Kontaktelement und dem Leiter erzielt. Es versteht sich von selbst, daß zur Erzielung einer optimalen Montage und Klemmung der Übergang vom verengten Bereich zum Inneren der Klemmhülse (leicht) schräg verlaufend ausgebildet ist.
Das vorstehend beschriebene Kontaktelement ist vorzugsweise zum Anschluß von mehrdrähtigen Litzenleitern vorgesehen.The clamping sleeve 3 shown as an individual part in FIG. 3 is screwed onto the sleeve 6. For this purpose, the clamping sleeve is provided with an internal thread 12. Furthermore, the clamping sleeve has an inner, narrowed edge 13 which, when the clamping sleeve is screwed onto the contact element, is pressed against the slotted area of the sleeve of the contact element and radially compresses this area. The conductor previously inserted into the sleeve is clamped and a perfect electrical and mechanical connection between the contact element and the conductor is achieved. It goes without saying that the transition from the narrowed area to the inside of the clamping sleeve (slightly) is inclined to achieve optimal assembly and clamping.
The contact element described above is preferably provided for connecting stranded stranded wires.

Zur Verbesserung der mechanischen und elektrischen Verbindung kann vorgesehen sein, daß die Bohrung 7 der Hülse 6 mit einem Innengewinde oder ein Riffelung versehen ist. Beim Aufschrauben der Klemmhülse und Zusammendrücken des geschlitzten Bereichs graben sich die Gewindespitzen bzw. die Riffelung in den Leiter ein und verbessern so die Kontaktierung. Diese Ausgestaltung des Kontaktelementes eignet sich insbesondere für den Anschluß von eindrähtigen Massivleitern.Can improve the mechanical and electrical connection be provided that the bore 7 of the sleeve 6 with an internal thread or is corrugated. When screwing on the clamping sleeve and Squeezing the slotted area digs the thread tips or the corrugation in the conductor and thus improve the contact. This configuration of the contact element is particularly suitable for the connection of solid solid conductors.
