Abstract

Für einen Staubsauger mit einem Saugschlauch ist eine Drehkupplung mit einem Anschlußstutzen (8) des Saugschlauches und einer im Gerätegehäuse vorgesehenen Anschlußhülse (5) vorgesehen. Der Anschlußstutzen (8) ist drehbar in die Anschlußhülse (5) einsetzbar, wobei am Anschlußstutzen (8) wenigstens eine elektrische Schleifringfläche (9) und an der Anschlußhülse (5) wenigstens ein Gegenkontakt (7) angeordnet ist. Um einen einfachen Aufbau zu erreichen, ist die Schliefringfläche (9) auf der außenliegenden Mantelfläche des Anschlußstutzens (8) und der Gegenkontakt (7) an der inneliegenden Mantelfläche (6) der Anschlußhülse (5) angeordnet. Die Achse der Anschlußhülse (5) bzw. des Anschlußstutzens (8) ist in der Betriebslage und in der Hauptbewegungsrichtung (4) des Gerätegehäuses unter einem spitzen Winkel nach oben gerichtet. A rotary coupling is included for a vacuum cleaner with a suction hose a connecting piece (8) of the suction hose and one in the device housing provided connection sleeve (5). The connecting piece (8) is Can be rotatably inserted into the connecting sleeve (5), with the connecting piece (8) at least one electrical slip ring surface (9) and on the Connection sleeve (5) at least one mating contact (7) is arranged. Around To achieve a simple structure, the closing ring surface (9) is open the outer surface of the connection piece (8) and Mating contact (7) on the inner surface (6) of the connecting sleeve (5) arranged. The axis of the connecting sleeve (5) or Connection piece (8) is in the operating position and in the Main direction of movement (4) of the device housing at an acute angle directed upwards.
