Abstract (en)
[origin: EP0307735A1] In the rotary coupling for latching a suction hose with electric conductors to the body of a vacuum cleaner, the electric conductors, provided in or on the suction hose, are electrically connected to a circuit present in the body of the vacuum cleaner via a movable contact arrangement which consists of slip rings and sliding contacts. A compact construction of the coupling is achieved in that the slip rings (11, 12) are arranged concentrically in the radial direction on the part of the coupling sleeve (5), which can be plugged into the coupling receptacle (2), and the sliding contacts (21, 22) are arranged axially movably under spring force in the coupling receptacle (2). <IMAGE>
