Abstract

The present disclosure provides a magnetic coil assembly for suppressing the generation of broken wire in a coil as well as reducing a winding time, the magnetic coil assembly according to the present disclosure comprise a bobbin; a magnetic coil wound around the bobbin; a pair of terminals fixedly installed at the bobbin; a first coil fixing protrusion portion extended from the terminal to fix a starting end portion of a first coil half which is a half of the entire length of the magnetic coil; a second coil fixing protrusion portion extended from the bobbin to fix a starting end portion of a second coil half which is the remaining half of the magnetic coil, and fix an terminals end portion of the first coil half; and a third coil fixing protrusion portion extended from the terminal to fix a terminal end portion of the second coil half.

Description

technical field [0001] The present disclosure relates to magnetic contactors, and more particularly, to magnetic coil assemblies for magnetic contactors. Background technique [0002] refer to figure 1 , generally, the exposed portion of the magnetic contactor 100 can be roughly divided into an upper frame 10 and a lower frame 20 . [0003] Refer to as internally configured figure 2 , figure 1 A typical magnetic contactor 100 may include a fixed core 1, a movable core 4, a coil 33, a bobbin 31, a cross bar 8, a movable contact 6, a fixed contact 7, and a return spring 9, and the above-mentioned components are housed on the frame 10 and lower frame 20. [0004] The fixed core 1 may be fixed and disposed at the inner bottom surface of the lower frame 20 and configured in a divided 'E'-shaped core. The bobbin 31 may be inserted into the central portion of the 'E'-shaped fixed core 1 , and the coil 33 may be wound around the bobbin 31 . Therefore, when the current flows i...
