<p>A heatable current collector (2) for establishing an electrical contact between a current carrying line (4) and an electric vehicle (6) is disclosed, with at least one sliding contact rail (10) arranged substantially transversely to the current carrying line (4), which has at least one bored hole (14) in which in each case an electrically operated, elongate heating element (18) is arranged, which occupies only a portion of the cross section of the bored hole (14). According to the invention, the heating element (18) is connected to a clamping device (20) which presses the heating element (18) against an inner side of the bored hole (14). Furthermore, a heating device (12) for the heatable current collector (2) is disclosed, with a substantially rigid, rod-shaped heating element (18) with an electrical resistance heating conductor (36) and two free ends (30, 32). According to the invention, the heating device comprises an inherently stable, resilient and thermostable hose (22) which is sealed off at one end (24), wherein the sealed off end (28) of the hose (26) is firmly connected to one (30) of the free ends of the heating element (18).</p> |
