Description

are offset by a certain angle. 40 In the German Auslegeschrift 1116 768 is

an electrical coupling described in which a pair of contacts from a flat intermediate housing wall

is provided as a slip ring and a plurality of contact springs sliding on the partition, 45 the mounting of which a mutual axial displacement

The invention relates to a current transmission that excludes, as contact springs, however,

Transmission device for the transmission of electrical energy. Use of closed disc springs. These require

In the case of a slip ring arrangement in the German interpretation.

132613 such a device described are In a further development of the invention, the contact-contact pairs from segment-shaped contact spring steel strips opposite the plane of the slip ring in this way Chen bent with contact rivets carrying contact tongues and 55 that they against the flat surface of the known with a slip ring. Press two contact rings at a time, Spring plates are used as double pantographs on both The wear on the slip rings is additional Sides of a circular arc-shaped contact carrier Hch reduced in that the ends of the contact fastened, which in turn stripes on two guide pins of each slip ring in different ways is arranged axially displaceable. 60 distances from the axis of rotation of the contact pair lie-die axially movable bearing of the double streams.

The large number of defined contact points should allow a customer on two guide pins
