Detailed description of the invention
Embodiment one
As it is shown in figure 1, a kind of maintenance electromagnetic relay coil assembly, including base 1, pole, it is articulated on pole 2
Armature 3, the iron core 4 being fixed on base 1 and the coil being wrapped on iron core 4, one end of described armature 3 and the position of iron core 4
Correspondence, is provided with elastic component 5 between the other end and the base 1 of described armature 3, described elastic component 5 is spring, and described iron core 4 sets
Having permanent magnet 6, when armature 3 and iron core 4 separate, described permanent magnet 6 is less than armature 3 and iron core 4 to the suction of armature 3
The suction-combining force, the suction-combining force be instigate armature 3 and iron core 4 absorption Guan Bi need suction.Described permanent magnet 6 is arranged on iron core 4
Internal.
When armature 3 and iron core 4 separate, described permanent magnet 6 to the suction of armature 3 less than armature 3 and iron core 4
The suction-combining force, permanent magnet 6 will not make armature 3 and iron core 4 adhesive to the suction of armature 3, when to coil electricity, making coil and permanent magnet
The magnetic pole of 6 is identical, then coil and permanent magnet 6 can make armature 3 action and iron core 4 adhesive to total captivation of armature 3, after adhesive,
The distance of permanent magnet 6 and armature 3 diminishes, and to coil blackout or reduction voltage, now the suction of armature 3 be enough to tie up by permanent magnet 6
Hold the adsorbed state of armature 3 and iron core 4, the only coil by permanent magnet 6 itself or permanent magnet 6 and applying small voltage can keep continuing
The state of electrical equipment.When needing to make armature 3 separate with iron core 4, apply reverse current to coil, formed contrary with permanent magnet 6 magnetic pole
Magnetic field, weaken the permanent magnet 6 suction to armature 3, under the reset response power of elastic component 5, armature 3 separates with iron core 4.
Embodiment two
As in figure 2 it is shown, the difference of the present embodiment and embodiment one is, described iron core 4 is internal is provided with receiving space
