Abstract:
A vacuum-cleaner hose with electrical conductors, comprisinga hose made of a soft thermoplastic material and exhibiting spiral, screw-like wave crests and wave troughs at an outer face;a support carrier attached at one end of the hose, wherein the support carrier is made out of a harder material than the material of the hose, and wherein the support carrier is formed ofa socket ring and a sleeve disposed in front of the socket ring;a continuous axial slot provided at the sleeve;at least one slip ring placed onto the socket ring, and two additional slip rings placed onto the sleeve;an end socket inserted into the one end of the hose exhibiting the support carrier, wherein the end socket is connected to the support carrier and is made of the same material as the support carrier, and wherein the sleeve is connected on the one hand form-matchingly to the socket ring and on the other hand form-matchingly to the end socket;at least one thread turn formed at an inner jacket face of the sleeve, wherein the thread turn forms a counter thread for the wave troughs and the wave crests of the hose;electrical conductors, wherein one of the electrical conductors is in each case connected to one slip ring;a protective casing disposed in the hose, wherein ends of the electrical conductors are guided out of the protective casing, first into the axial slot of the sleeve and then to the slip rings, coordinated to the ends of the electrical conductors and openly disposed inside the axial slot.
