The present invention operation principle be：
First pole piece 5 and the second pole piece 6 are magnetized, and polarity is different, and polarity immobilizes, and such as scheme, this embodiment party
It is that the first pole piece 5 is in S polarity in formula, the second pole piece 6 is in N polarity.
When coil 4 is positive to be powered, positive magnetic field can be produced by the law of electromagnetic induction, the first yoke 1--- iron cores 3--- the
Two yokes 2 collectively form magnetic conductor, and the first yoke 1 and the polarity of the second yoke 2 are different.It is that the first yoke 1 is in present embodiment
N polarity, the second yoke 2 are in S polarity.First pole piece 5 and the different generation suction of the magnetic of the first yoke 1, the second pole piece 6 and
The different generation suction of the magnetic of two yoke 2, therefore, permanent magnet assembly is deflected centered on axle center 13, the first pole piece 5 and
The adhesive of one yoke 1, the second pole piece 6 and the adhesive of the second yoke 2.Therefore, first yoke 1--- iron cores the second yokes of 3--- 2---
Second the first yokes of pole piece 6--- permanent magnets 7--- the first pole piece 5--- 1 form closed magnetic loop, even if after coil 4 powers off
Still adhesive can be kept (i.e. magnetic is kept).In said process, moving contacting plate 12 also turns to its both ends centered on axle center 13
Contacted respectively with the first quiet contact chip 8, the 3rd quiet contact chip 10, i.e. the first quiet contact chip 8, the 3rd quiet contact chip 10 pass through dynamic
Contact chip 12 realizes electrical connection, realizes product turn-on power loss.
When coil 4 is reversely powered, opposing magnetic field can be produced, what first the second yokes of yoke 1--- iron cores 3--- 2 were formed
Magnetic conductor magnetic polarity changes, and the polarity of the first yoke 1 is changed into S poles, and the second yoke 2 is in N poles, now the first yoke 1 and first
The identical generation repulsion of the polarity of pole piece 5, the second yoke 2 generation repulsion identical with the polarity of the second pole piece 6, therefore, permanent magnet group
Part is deflected centered on axle center 13 under repulsion effect；While rotation, the polarity of the first pole piece 5 and the second yoke 2
Different generation suction, the different generation suction of polarity of the second pole piece 6 and the first yoke 1, therefore, the first pole piece 5 and second
The adhesive of yoke 2, the second pole piece 6 and the adhesive of the first yoke 1.First yoke 1--- iron cores 3--- the second yoke the first magnetic poles of 2---
The first yokes of piece 5--- permanent magnets 7--- the second pole piece 6--- 1 form closed magnetic loop, even if coil 4 still can be with after powering off
Keep adhesive (i.e. magnetic is kept).In said process, moving contacting plate 12 also turns to its both ends respectively with centered on axle center 13
Two quiet contact chips 9, the 4th quiet contact chip 11 contact, i.e. the second quiet contact chip 9, the 4th quiet contact chip 11 pass through moving contacting plate 12
Electrical connection is realized, realizes product turn-on power loss.
Therefore, after balanced force type magnetic latching contactor of the present invention is powered, coil 4 keeps electric current also being capable of magnetic guarantor without providing
Hold, avoid the product function failure under powering-off state；Can also be by controlling forward and reverse energization to control cutting for product circuit
Change, with the switching of magnetic structure control circuit, so as to which contact stress balance, shock resistance are stronger.
