The invention relates to the technical field of relays, and particularly discloses a pushing mechanism of a relay, which is low in production cost and high in assembly efficiency. The pushing mechanism comprises a casing body, a movable contact bridge, an insulating sleeve, a pressure spring and a pushing rod. The casing body is provided with an accommodating groove, and a limiting convex rib is arranged in the accommodating groove. The movable contact bridge is accommodated in the accommodating groove and abuts against the limiting convex rib. A through hole is formed in the movable contact bridge. The insulating sleeve comprises a base, a sleeve rod and a limiting block. Two ends of the sleeve rod are connected with the base and the limiting block respectively. The base is adjacent to the opening of the accommodating groove and abuts against the inner surface of the accommodating groove. The sleeve rod and the limiting block sequentially penetrate through the through hole and are insliding connection with the movable contact bridge. The length of the limiting block is larger than the width of the through hole. The limiting block is used for being stressed to rotate and abut against one face, adjacent to the bottom of the accommodating groove, of the movable contact bridge. The pressure spring sleeves the sleeve rod and abuts against the base and the movable contact bridge. The pushing rod is connected with the base and used for driving the insulating sleeve to move straightly or rotate relative to the movable contact bridge.
Description
technical field [0001] The invention relates to the technical field of relays, in particular to a pushing mechanism of a relay. Background technique [0002] The relay, also known as the electric relay, is an electronic control device with an input loop and an output loop. It is usually used in an automatic control circuit to facilitate the control of a larger current through a smaller current to achieve automatic adjustment of the circuit. Safety protection and conversion circuit, etc. Among them, the DC relay is a type of relay that uses DC current to work. The DC relay is mainly used in the protection interlocking system. Even in the case of the factory AC power failure, it can also trigger the protection circuit. Of course, its contacts must also be DC. system; DC relays are also used in high-power occasions. The electromagnetic force generated by DC relays is large, which is beneficial to control the main circuit; in addition, DC relays are also used in some occasions ...
