The invention provides a motor-type stable relay that comprises a housing, a driving motor, a connecting rod and a contact assembly. The contact assembly comprises a fixed contact connecting piece, a movable contact connecting piece and a movable spring piece. One end of the fixed contact connecting piece is provided with a fixed contact. One end of the movable contact connecting piece is connected with the fixed end of the movable spring piece. A movable contact is arranged at the movable end of the movable spring piece. A worm is arranged on the output shaft of the driving motor. A worm gear is arranged inside housing rotatably. A driving gear is arranged on the worm gear in a coaxially driving way. A driven gear is rotatably arranged in the housing. One end of the connecting rod is hinged to the driven gear and the other end of the connecting rod is connected with the movable end of the movable spring piece. The motor-type stable relay not only achieves precise control of the driving motor, but also can prevent the connecting rod from reversely rotating the driven gear, thereby preventing rigid pressing force from pressing a contact surface of the movable contact and the fixed contact and further forming an included angle, and enhancing conductivity and reliability.
Description
technical field [0001] The invention relates to a relay, in particular to an electromechanical stable relay. . Background technique [0002] At present, during the use of relays, especially in the use of motor-type relays, because the motor drives the spring piece to achieve the pull-in and disconnection of the contacts, due to the certain rigidity of the motor drive, the spring piece is deformed after long-term use , and when the pressing force at the end of the spring leaf is large, the movable contact and the static contact will form a fulcrum, so that the contact surfaces of the movable contact and the static contact form an included angle, which reduces the conductivity and reliability. Contents of the invention [0003] The technical problem to be solved by the invention is that the rigid pressing force driven by the motor in the existing motor relay makes the contact surfaces of the movable contact and the static contact warp to form an included angle, which reduce...
