TITLE: INSULATING STRUCTURE FOR TERMINAL OF DC MOTOR Abstract The present invention discloses an insulating structure for a terminal of a DC motor, comprising a terminal support; the terminal support comprises a support body fixed onto an inner side of a side wall of a motor end cover, and the support body is made of insulating material; a through hole for allowing the terminal to pass therethrough is formed on the motor end cover; a positioning bulge, extending into the first through hole, is fixed on the support body; one end of the terminal successively passes through a second through hole and the first through hole to extend to the outside of the motor end cover; a limiting groove is formed concavely on a side of the support body away from the inner side of the side wall of the motor end cover, and the second through hole is located within the limiting groove; a terminal lug is fixed at the other end of the terminal, and the terminal lug is located within the limiting groove; the shape of the limiting groove along the radial section of the first through hole is a polygonal structure, and the shape of the limiting groove along the radial section of the first through hole is the same as that of the terminal lug along the radial section of the first through hole.
