Die Fig. zeigen eine elektrische Drehkupplung 1 mit einer inneren und einer äußeren Schleifkontaktringanordnung 2,3 zum Übertragen von elektrischen Strömen, wobei die innere Schleifkontaktringanordnung 2 mit mehreren ersten Schleifringen 4 versehen ist, die einseitig in Richtung 6 der Achse nach außen führende erste Fahnen 7 aufweisen, wobei jeweils ein erster Schleifring 4 mit einer ersten Fahne 7 einen einstückigen Aufbau aufweist. Die äußere Schleifkontaktringanordnung 3 ist mit mehreren zweiten Schleifringen 5 versehen, die einseitig in einer entgegengesetzten Richtung 9 der Achse nach außen führende zweite Fahnen 8 aufweisen, wobei jeweils ein zweiter Schleifring 5 mit einer zweiten Fahne 8 einen einstückigen Aufbau aufweist. Die zweiten Schleifringe 5 sind mit mehreren Federkontakten 10 versehen, die durch Materialausnehmung und Verformung gebildet sind. Die Federkontakte 10 der zweiten Schleifringe 5 stehen mit jeweils einer äußeren Schleifringoberfläche 18 der ersten Schleifringe 4 koaxial in elektrischem Kontakt. Dadurch ergibt sich ein einfacher, kompakter Aufbau der Kupplung 1 sowie eine sehr gute elektrische Leitfähigkeit, da die elektrischen Übergangsstellen (Kontakt- und Lötstellen) auf ein Minimum beschränkt sind.The figures show an electric rotary joint 1 with an inner and an outer sliding contact ring arrangement 2, 3 for transmitting electrical currents, the inner sliding contact ring arrangement 2 being provided with a plurality of first slip rings 4, the first lugs 7 leading outwards in the direction 6 of the axis each having a first slip ring 4 with a first flag 7 has a one-piece construction. The outer Schleifkontaktaktringanordnung 3 is provided with a plurality of second slip rings 5, which have unilaterally in an opposite direction 9 of the axis outwardly leading second lugs 8, wherein in each case a second slip ring 5 with a second lug 8 has a one-piece construction. The second slip rings 5 are provided with a plurality of spring contacts 10, which are formed by Materialausnehmung and deformation. The spring contacts 10 of the second slip rings 5 are in electrical contact with a respective outer slip ring surface 18 of the first slip rings 4 coaxially. This results in a simple, compact design of the coupling 1 and a very good electrical conductivity, since the electrical interfaces (contact and solder joints) are kept to a minimum.

In der Fig. 2 ist in einer Abwicklung der erste Schleifring 4 mit einer ersten Fahne 7 als elektrischer Leiter dargestellt, der eine T-Form aufweist. Das Ende der ersten Fahne 7 ist eine Kontaktzunge 13 ausgestaltet.

Zum Umbiegen der ersten Fahne 7 sind kleine Ausschnitte 26 angeordnet. Die ersten Schleifringe 4 werden durch eine formschlüssige Nutverbindung 11 gebildet, insbesondere durch eine Schwalbenschwanz-Feder/Nut-Verbindung, die sich durch Umbiegen zu einem Ring 4 ergibt.In FIG. 2, the first slip ring 4 with a first lug 7 as an electrical conductor, which has a T-shape, is shown in a development. The end of the first flag 7 is a contact tongue 13 configured. Depending on the axial arrangement of the first slip rings 4 on the rotor 16, a certain length of the first lug 7 is required so that the contact tongues 13 for a plug connection 14 terminate at the same level. For bending the first flag 7 small cutouts 26 are arranged. The first slip rings 4 are formed by a positive groove connection 11, in particular by a dovetail spring / groove connection, which results by bending over into a ring 4.

Das Ende der zweiten Fahne 8 ist für eine Lötverbindung 15 ausgebildet. Wahlweise kann auch eine Steckerverbindung 14 vorgesehen werden. Je nach axialer Anordnung der zweiten Schleifringe 5 ist eine bestimmte Länge der zweiten Fahne 8 erforderlich, damit die Lötverbindungen 15 auf gleicher Ebene abschließen. Zum Umbiegen der zweiten Fahne 8 sind kleine Ausschnitte 26 angeordnet. Die zweiten Schleifringe 5 werden durch eine formschlüssige Nutverbindung 11 gebildet, insbesondere durch eine Schwalbenschwanz-Feder/Nut-Verbindung, die sich durch Umbiegen zu einem Ring 5 ergibt. Wahlweise ist der Endbereich 12 der ersten oder der zweiten Fahnen 7,8 als Kontaktzungen 13 einer Steckverbindung 14 oder als Lötverbindung 15 vorgesehen.3, the second slip ring 5 is shown with a second lug 8 as an electrical conductor in a development, which has a T-shape.
