The current collector is one of the main devices on the conductor rail system to pick up electric energy. It conducts the electric energy directly to the electrical appliances through the sliding contact between the collector brush and the guide rail, so as to realize the mobile power supply of the system. The current collector is composed of two parts: the tension device of the mechanical structure and the current collector brush which is in direct sliding contact with the guide rail. The tension device of the mechanical structure determines the sliding contact pressure between the collector brush and the guide rail and the stability of the mechanism. Sliding contact to pick up electrical energy conductor, its performance and conductive quality and the quality of material structure will directly affect the safe operation quality of the entire system equipment, so the current collector is one of the most important components in the entire conductor rail system.
