SIGNAL TRANSMISSION TROLLEY LINE

摘要

PURPOSE: To prevent the occurrence of running noises in transmitting signals without cleaning by reducing the contact resistance between a conductor and a trolley collector. CONSTITUTION: In a signal transmitting trolley line, the signal from a trolley 13, which is moved so that a trolley collector 14 is in contact with a conductor 12 supported by a connector receptacle 11, or the signal to the trolley 13 is transmitted through the conductor 12. The conductor 12 is a line body of the unitary constitution whose cross-sectional shape is circular, and is plated with gold. The trolley collector 14 is constituted of the sintered material of silver and graphite.
