A PANTOGRAPH HAVING PERSISTENCE AND COHERENCE

摘要

PURPOSE: A pantographe is provided to maintain a coupling force in abrasion, thereby increasing lifetime of a main wearing slider. CONSTITUTION: A main wearing slider(150) has gradient(151) on a contact part on which an electric vehicle wire is contacted and has attaching grooves(155) on both sides thereof. The main wearing slider(150) has an inclined side(153) on both sides to facilitate injection of the electric vehicle wire when falling down. A clamp(130) has a hook(131) which is bent inwards to correspond to the attaching groove and controls adhesion to a grounding plate by an adhesion-control unit(200).
