The present disclosure relates to the technical field of electrical connection, in particular to a self-coupled wire connector using a bend spring sheet and conductor sheet, including a main body, a spring sheet and a conductor sheet; a coupling space for accommodating the spring sheet and the conductor sheet is formed inside the main body; a wire plugging hole passing through the coupling space is formed in the main body; the spring sheet and the conductor sheet are assembled in the coupling space, and are kept in a self-coupling state through the coupling space; a wire presses against the spring sheet and the conductor sheet to force the spring sheet and the conductor sheet to be self-coupled.
