A telescopic tube (1)for an electric household appliance is described, said tube comprising a first outer tube (2) and a second inner tube (3) slidable inside said first outer tube (2), and electricity conduction means (10,18,20) for conducting electricity from first tube (2) to second tube (3). The conduction means comprise: a) an elongate guide body (7) made of a non electrically conductive material; b) a locking member (5) for connecting the first end of said elongated guide body (7) to said second inner tube (3); c) an outer channel (6) connected to an outer surface of said first outer tube (2), said outer channel (6) being provided for slidingly receiving said elongated guide body (7); d) a pair of tubular-shaped electric conductors (18) contained in said elongated guide body (7); and e) a corresponding pair of substantially rigid rod-shaped electric conductors (10) which are able to slide, at least partially, within said tubular-shaped electric conductors (18)so that each rod-shaped electric conductor (10) is in contact with an inner surface of a corresponding tubular-shaped electric conductor (18).

L'invention concerne un tube télescopique (1) pour un appareil électroménager, ledit tube comprenant un premier tube extérieur (2) et un second tube intérieur (3) coulissant à l'intérieur dudit premier tube extérieur (2), ainsi que des moyens de conduction électrique (10,18,20) conçus pour conduire l'électricité du premier tube (2) au second tube (3). Les moyens de conduction comprennent : a) un corps de guidage allongé (7) constitué d'un matériau non électriquement conducteur ; b) un élément de verrouillage (5) conçu pour relier la première extrémité dudit corps de guidage allongé (7) audit second tube intérieur (3) ; c) un canal extérieur (6) relié à une surface extérieure dudit premier tube extérieur (2), ledit canal extérieur (6) étant conçu pour recevoir de manière coulissante ledit corps de guidage allongé (7) ; d) une paire de conducteurs électriques de forme tubulaire (18) contenue dans ledit corps de guidage allongé (7) ; et e) une paire correspondante de conducteurs électriques en forme de tiges sensiblement rigides (10) pouvant coulisser, au moins partiellement, dans lesdits conducteurs électriques de forme tubulaire (18) de sorte que chaque conducteur électrique en forme de tige (10) est en contact avec une surface intérieure d'un conducteur électrique de forme tubulaire correspondant (18).
