The movable contact mounting assemblies 141 and 142 include snap springs 141a and 142a, bridge springs 141b and 142b, and spacers 141c and 142c, which are engaged with each other, and the movable contacts 131 and 132 are sleeved outside the movable contact positioning rods 121 and 122 through the bridge springs 141b and 142b, and are fixed under the engagement of the snap springs 141a and 142a and the spacers 141c and 142 c.
A main rod 150 is installed at the other side 112 of the exciting rod 110, and a movable iron core 170 is installed on the main rod 150 through a movable iron core installation component 160;
the plunger mounting assembly 160 includes a compression spring 161 and a snap spring 162, which are engaged with each other, and the plunger 170 is mounted on the outside of the main rod 150 by the compression spring 161 and fixed by the snap spring 162.
The insulating plate 180 is sleeved on the moving contact positioning rods 121 and 122 between the moving contacts 131 and 132 and the exciting rod 110; and the end 151 of the main rod 150 is further sleeved with a stationary core 190, the lower surface of the insulating plate positioning frame 181 is in contact with the upper surface of the stationary core 190 and the lower surface of the excitation rod 110, and the excitation rod 110 can move up and down between the insulating plate 180 and the stationary core 190.
