1, when coating is handled, because process technology limit, the two ends of U type yoke are all applied, and the joint end 131 of U type yoke does not need to apply, can increase the magnetic resistance between the support end 31 of the joint end 131 of U type yoke and iron core member 3 like this, influence the characteristic of relay;
2, coating layer thickness is had strict required precision, this brings certain difficulty just for the actual production technology controlling and process, causes bad generation.
3, because the coating layer thickness and the degree of depth are had strict required precision, the coating complex treatment process, cost is higher.
The utility model content
The technical problems to be solved in the utility model is to reduce the magnetic force loss of polarity electromagnetic relay magnetic circuit, improves its performance; Simplify the technology controlling and process requirement of yoke, reduce the fraction defective of product, reduce production costs simultaneously every the magnetic treatment process.
In order to address the above problem, this use is novel to provide a kind of yoke that is used for polarity electromagnetic relay, it is characterized in that the side of an end of described yoke is welded with antifreeze plate.
As preferably, described antifreeze plate is nonmagnetic sheet metal.
As preferably, the U type that is shaped as of described yoke.
This use is novel also to provide a kind of polarity electromagnetic relay simultaneously, comprise coil component, two yokes setting up relatively on support body and the described support body, be equipped with iron core member in the described coil component, described iron core member comprises support end and swinging end, two described yokes comprise joint end and absorption end, the support end of described iron core member is connected between the joint end of two described yokes, the swinging end of described iron core member be contained between the absorption end of two described yokes and with the side absorption of the absorption end of one of them yoke, it is characterized in that the absorption end of two described yokes is welded with antifreeze plate with the side that described iron core member swinging end adsorbs mutually.
Preferably, the U type that is shaped as of described yoke.
The beneficial effects of the utility model are, take antifreeze plate that the absorption end of yoke is carried out every magnetic, every the magnetic effect stability, easier action of polarity electromagnetic relay and release, and reduced magnetic force loss unnecessary between the support end of the joint end of yoke and iron core member.It is simple to have production technology in addition, reduces fraction defective, reduces the advantage of product cost.

Embodiment
Describe execution mode of the present utility model with reference to the accompanying drawings in detail.
To shown in Figure 6, polarity electromagnetic relay of the present utility model comprises support body 12, two U type yokes 13, iron core member 3, driver card 4 etc. as Fig. 3; Two U type yokes 13 relatively insert inner being equipped with in the support body 12 of permanent magnet.One end of U type yoke 13 is a joint end 131, the other end is absorption end 132, iron core member 3 comprises fulcrum 31 and swinging end 32, the swinging end 31 of iron core member 3 passes coil component 2, sheathedly on the position of iron core member 3 then be used to drive the driver card 4 that relevant contacts opens and closes near swinging end 31, pack at last in the support body 12, the support end 31 of iron core member 3 is stuck between the joint end 131 of two U type yokes 13, the swinging end 32 of iron core member 3 is adsorbed on the side of absorption end 132 of one of them U type yoke 13, forms closed magnetic circuit between the U type yoke 13 of iron core member 3 and its absorption.
Under the situation of not switching on, the swinging end 32 of iron core member 3 under the magneticaction of permanent magnet with the side absorption of the absorption end 132 of one of them U type yoke 13; Under the energising situation, coil generates an electromagnetic field, and is subjected to the effect of electromagnetic field, and the swinging end 32 of iron core member 3 separates with the absorption end 132 of its adsorbed U type yoke 13, is flapped toward the absorption end 132 of another U type yoke 13 and is adsorbed on its side.The swinging end 32 of iron core member 3 can be swung between the absorption end 132 of two U type yokes 13, thereby drives driver card 4 motions, changes the open and-shut mode of contact.
