Electrically heatable flexible tube, in particular for window or headlamp cleaning systems of motor vehicles

摘要

An electrically heatable flexible tube as feed or discharge line for a fluid, in particular for window or headlamp cleaning systems of motor vehicles, is known with an electrical conductor which is arranged inside the flexible tube and extends between two fluid connection pieces of the flexible tube. To specify an electrically heatable flexible tube which can be produced in a cost-advantageous manner using standard components, but which nevertheless makes it possible for the flexible tube to be effectively heated up to its ends, a bare (uninsulated), flat strip of metal is used as conductor, which is twisted about its longitudinal axis, the connecting pieces at the two ends of the flexible tube are T-pieces, the metal strip being passed out through the one free end of these T-pieces and clamped against the outside of this end and the metal strip being connected at the clamping point to an NTC thermistor.
