本発明は電磁装置のヨークに関し、その目的とするとこ

なしたるものである。For example, as shown in Figure 1, there are multiple leg pieces a like an E-type yoke.
, b, c The yoke 1 of the electromagnetic device is integrally formed by punching out a single sheet of magnetic material.
, c is deformed. Figure 2 shows a combination of the yoke 1 with the leg b inclined and the armature 2, and Figure 3 shows the leg pieces a and b.
By creating a gap G between the yoke 1 and the armature 2, the suction force is reduced and the armature 2 is reversed. The stroke changes, and when such an electromagnetic device is used as a relay, the contact characteristics change. The present invention has been made in view of the above-mentioned problems and as a countermeasure thereof.

ものである。The yoke of the electromagnetic device of the present invention will be explained below with reference to the drawings listed as examples. Figures 4 to 6 are examples of the present invention, and have leg pieces a, b, and c. A magnetic material portion 1a and a non-magnetic material portion Ib are connected and integrally formed in the magnetic material constituting the yoke 1, and window holes 3a and 3b are bored across the magnetic material portion 1a and the non-magnetic material portion Ib to form the yoke. The yoke of the electromagnetic device is characterized in that the open ends of the legs a, b, and c of the yoke 1 are closed by non-magnetic material parts lb.

の変化を極減し得ることゝなる。According to such a yoke 1, the non-magnetic material portion Ib is the leg piece a,
Since the open ends of b and c are closed, there is no deformation of the yoke 1 during punching, plating, transportation, and assembly 15. There is no flatness between the yoke 1 and the armature 2. This improves magnetic efficiency and improves attraction characteristics, and in the case of relays, changes in contact stroke can be minimized.

ある。20 Fig. 7 shows another embodiment, in which the three leg pieces a, b, and c of the E-shaped yoke are integrally formed in the previous embodiment, but in this embodiment, both sides of the legs are integrally formed. The leg pieces a and c are made of a magnetic material composed of a magnetic material part 1a and a non-magnetic material lb, and the intermediate leg piece b is made of a magnetic material part 1a.
In this case, the open ends of the leg pieces a and c on both sides are made of non-magnetic material part I.
Since it can be made flat by closing b, it is possible to give the contact stroke accurately, even if the magnetic efficiency is slightly degraded.
This has the advantage that the coil 4 can be easily attached.

与えることゝなる。As described above, according to the yoke of the electromagnetic device of the present invention, some of the open ends a, b, c of the yoke 1 made of a magnetic material are closed by the non-magnetic material portion Ib. Therefore, it improves magnetic efficiency, facilitates processing, and provides effects such as making the contact stroke constant in relays.
