VOLTAGE TRIP DEVICE

摘要

PURPOSE: A voltage trip device is provided to prevent a disassembling phenomenon of a movable core due to a tilt angle of the movable core by minimizing an aperture between an inside diameter of a bobbin and an outside diameter of the movable core. CONSTITUTION: A coil(12) is wound around an outside of a cylindrical bobbin(11). A left yoke(13) and a right yoke(13') are formed at a left side and a right side of the cylindrical bobbin(11). A fixed core(14) is fixed to one side of the outside of the bobbin(11). A movable core(15) is installed at the other side of the outside of the bobbin(11). A pin(16) is formed in the right yoke(13'). A rear end part of the movable core(15) is combined with one end part of a lever(17). The lever(17) is elastically supported by a torsion spring(19). A plurality of air exhaustion grooves(20) is formed to a longitudinal direction of an outer circumference of the movable core(15).
