Transmission connection structure for high current DC contactor

The invention discloses a transmission connection structure for a high current DC contactor. The action of an electromagnet is transmitted to a control switch and is converted into a control signal tobe sent to a locomotive control system to a remote end. The transmission connection structure comprises a spring system, a support seat (8), a moving contact (9), a static contact (10), a conductivecopper bar (11), a micro-switch action mechanism and a housing (19). The transmission connection structure has the advantages of a simple structure and easy installation, the unified management of product quality is facilitated, and combined with a suction electromagnet with more stable output, the problem of the sharp increase of an external dimension of the contactor after the capacity is increased can be solved. The contactor used in the limited space of a locomotive provides a sufficient open distance, the number of transmission parts is reduced, the transmission efficiency is improved, and the reliability of trans
