Abstract (en)

[origin: EP0835632A2] The arrangement comprises at least two hollow tube parts which are inserted into each other and mechanically coupled to sections of the telescopic tube. The tube parts include electric connector devices at ends which oppose each other. The electric connectors are connected to each other over an electric conductor which is arranged in the interior of the tube parts. A section of the electric conductor in the interior of the tube part which is stationary w.r.t. to the other tube part, is arranged as a coil. Elastic clamp parts are pref. formed in the tube part with the coiled conductor to prevent tensions on the conductor, whereby one clamp part is arranged at the end of the connector, and the other end is arranged at the end of the moving tube part, where the conductor is inserted.
