A LINKAGE STRUCTURE OF THE MOVING CONTACT OF THE MODULAR CIRCUIT BREAKER

摘要

A linkage structure of a moving contact of a modular circuit breaker, comprising: a first housing (101) and a second housing (102), the first housing (101) and the second housing (102) respectively having a first mounting hole (110) and a second mounting hole (120), the position of the first mounting hole (110) and the second mounting hole (120) being corresponded; a first short axis (103); an operating mechanism side plate (104); the operating mechanism side plate (104) having a third through hole (140), the third through hole (140) located in the position which is corresponded to the rotational center of the position of the contact rotor (106); an operating mechanism lower link rod (105), the operating mechanism lower link rod (105) having a fourth through hole, the fourth through hole docking with the first minor axis (103); a contact rotor (106), the contact rotor (106) rotating around the rotational center, both sides of the contact rotor (106 ) having matching surfaces; a first linkage block (107), connected to the matching surface of the first side of the contact rotor (106); a second linkage block (108), connected to the matching surface of the second side of the contact rotor (106); the contact rotor (106), the first linkage block (107) and the second linkage block (108) mounted in the first mounting hole (110) and the second mounting hole (120).
