Heatable current collector for producing electrical contact between a current-carrying line and an electric vehicle, and heating device for use in the current collector

摘要

A heatable current collector for establishing an electrical contact between a current carrying line and an electric vehicle includes a lifting mechanism, a sliding contact rail, a rod, an electrical resistance heating conductor and a resilient hose. The rail is mounted on the lifting mechanism and has a longitudinal hole disposed perpendicular to the current carrying line. The electrical resistance heating conductor is disposed in grooves of an outer threading of the rod. One end of the resilient hose is sealed off and is connected to an end of the rod. The rod, the electrical resistance heating conductor and the resilient hose are disposed in the hole. The resilient hose presses the rod and the electrical resistance heating conductor against an inside surface of the hole. The hole is formed so close beneath a surface of the rail that a section of the hole forms a slit in the surface.
