STRUCTURE FOR FIXING SHADING COIL OF MAGNETIC CONTACTOR

摘要

PURPOSE: A structure for fixing a shading coil of a magnetic contactor is provided to achieve operational safety of a magnetic contactor and enhance productivity of the magnetic contactor by simply fixing a shading coil. CONSTITUTION: A fixed core(20) generates a magnetic force of pulling a movable core by being magnetized by the bobbin coil applied power. A lower frame(10) allows the bobbin coil and the fixed core(20) to be seated thereon. An upper frame is coupled with the lower frame(10) on an upper side thereof and allows the movable core to be mounted thereon. An annular shading coil(70) reduces a chattering phenomenon generated when the fixed core(20) is magnetized. Line grooves(10a,20b) are respectively formed on an upper surface of the lower frame(10) and an upper surface of a lateral side end of the fixed core(20) to let the shading coil(70) be inserted thereinto. A side of the shading coil(70) is fixed as the upper frame(12) is coupled with the lower frame(20) in a state where the shading coil is inserted into the line grooves(10a,20b).
