2. Description of the Related Art As an electromagnetic device for a polarized relay or the like, one in which an electromagnetic block has an E-shaped magnetic path is known. That is, as shown in FIG. 1, this uses an electromagnetic block A in which a yoke 3 is constructed such that an iron core 2 around which a coil 1 is wound is located in the center of the letter E. The permanent magnet block B to be combined with this is formed in a U-shape so that the ends of two magnetic pieces 5, 5 on the same side are in contact with both sides of the permanent magnet 4 in the direction of magnetization. When both blocks A and B are arranged as shown in Fig. 1 and the direction of the current flowing through the coil 1 is changed, the magnetic piece 5 is attracted to the magnetic pole part 2a of the iron core 2 or the magnetic pole part 3a of the yoke 3. or A polarized relay uses this action to open and close a contact mechanism.

When the outer diameter of the coil 1 wound around the iron core 2 is large,
The drawback is that the magnetic pole part requires complicated bending, and the yoke is easily deformed. On the other hand, the third
The one shown in the figure has the advantage that it does not have the above disadvantages and is suitable for the latching type in terms of magnetic efficiency, but in order to obtain single stable operation,
This is inconvenient because strict demands are placed on dimensional accuracy, such as changing the opposing areas and maintaining a magnetic unbalanced gap in order to unbalance the attractive force characteristics.

ある。 The electromagnet device according to this invention also has an electromagnetic block A having a coil 1 and a permanent magnet block B having a permanent magnet 4 arranged as shown in FIG. However, it differs from the conventional one in that the yoke 3 of the electromagnetic block A is formed as shown in FIG. That is, although the electromagnetic block A basically has the configuration shown in FIG. The curved shape is such that the magnetic pole part 3a facing the iron core magnetic pole part 2a is not on both sides of the iron core magnetic pole part 2a as shown in FIG. 3, but on only one side as shown in FIG. 4. .

This auxiliary piece 6 can be brought into contact with the opposite end of the yoke piece 31 and connected magnetically to form another opposing magnetic pole part 3a. Since the auxiliary piece is a flat plate, it is easy to make a highly accurate one. Possible and preferable.

と言う利点もある。[Effect of the invention] As seen above, the electromagnet device according to the invention has a yoke formed by bending the magnetic pole part parallel to the iron core and facing the iron core magnetic pole part at the tip, and Since the magnetic pole portion is formed only on one side of the iron core magnetic pole portion, the bending process is simple, the yoke is less likely to deform, and the amount of winding of the coil can be increased. Material removal for the yoke is improved. Furthermore, the magnetic saturation of the yoke disappears, and the magnetic attraction characteristics required for a single stable type are difficult to achieve, such as creating a difference in area between the two opposing magnetic poles and creating an imbalance in the magnetic gap. can be obtained without any Another advantage is that the single stable type and latching type use the same yoke.
