description The utility model discloses a current collector limiting nail. The utility model belongs to the technical field of parts of rail transit vehicle power receiving equipment. The utility model discloses a current collector. When the current collector limiting nail impacts the limiting block, the generated noise is large; in order to solve the technical problems that a current collector limiting nail is prone to breakage in the prior art, external threads are formed on the outer wall of a threaded rod, an inserting groove capable of enabling the threaded rod to rotate is formed in one end of the threaded rod, a nut is fixedly connected to the other end of the threaded rod, and a protruding column is formed at the end, away from the threaded rod, of the nut and used for making rigid contact with a limiting block; the rubber block is fixedly connected to the outer portion of the nut and used for making flexible contact with the limiting block, a through hole capable of exposing the protruding column pre-buried in t
