Abstract:
A vacuum cleaner tube having electrical conductors comprisinga tube having an inner wall and formed spirally on the outside and formed smoothly on the inside and having an end; a helical step disposed at the tube; an end bush having a rear end and plugged into the end of the tube, wherein the end bush exhibits an axial slot having flanks and open at the rear end of the end bush; locking noses disposed at the end bush; a protective covering attached at the inner wall of the tube; a projection formed at the end bush and closed at its front end and formed for receiving the protective covering, wherein the flanks of the axial slot form a transition into the projection; a slip ring support having a longitudinal passing through slot for engaging the tube, wherein the slip ring support is made as a single part; first breakouts furnished at the slip ring support for an engagement of the locking noses formed at the end bush; a plurality of electrical conductors disposed in the protective covering; slip rings disposed on the slip ring support and connected in each case to a respective one of the plurality of electrical conductors, wherein the respective one of the plurality of electrical conductor is led to the coordinated slip ring through the axial slot of the end bush, wherein the end bush and the slip ring support are axially form matchingly and disengageably fixed in a final position; an intermediate sleeve having a front end and exhibiting a pass through slot congruent in its final position with the axial slot of the end bush and the passing through slot of the slip ring support; at least two second breakouts furnished at a front end of the intermediate sleeve, wherein in each case one of the locking noses formed at the end bush engages in the final position of the at least two second breakouts; a raised thread step disposed at the inner side of the intermediate sleeve and serving for axially form matchingly and disengageably fixing the end bush and the slip ring support in a final position, wherein the raised thread step is screwed to the helical step of the tube.
