The present utility model belongs to a novel casting conductor, buckling edge grooves are arranged on peripheral walls of two ports of a contact pedestal of a conductor pedestal, one end of a plum blossom contacting finer is fitted inside the buckling edge grooves, the other end of the plum blossom contacting finer is arranged outside the two ports of the contact pedestal, a spring ring is arranged on the outer wall of the plum blossom contacting finger, a shielding cover is wrapped outside the spring ring at intervals, and the shielding cover is fixed on periphery of the two ports. By adopting the conductor, holding force on a conductive rod can be reduced, load and friction coefficient of transmission machinery can be reduced, service life of a grounding switch is enhanced, and the conductor has advantages of simple structure, small and compact volume, reliability and safety, good stability, low costs and long service life.
