Abstract

PROBLEM TO BE SOLVED: To provide a polarized relay in which generation of clicking noise or beat is prevented. SOLUTION: A permanent magnet is arranged between both side pieces of an iron core around which a coil is wound, an armature 9 is arranged on the permanent magnet so as to be capable of swinging on a fulcrum 13, and both end parts in the length direction of the armature 9 are attracted to the both side pieces of the iron core, and thereby the armature 9 swings on the permanent magnet. Projections 9a, 9a are formed in a part of the armature 9 coming in contact with the both side pieces of the iron core, and since the armature 9 comes in contact with the side piece of the iron core at a point in the projection 9a, the contact of the armature 9 with the side piece of the iron core is stabilized. The fulcrum 13 is constituted with a projecting stripe 9b extending in the width direction of the armature 9 and molding parts 8b, 8b, and since the armature 9 comes in contact with the permanent magnet in a line in the fulcrum part 13, the contact of the armature 9 with the permanent magnet is stabilized.

Because The operation of the polarized relay will be briefly described. In this polarized relay, when the coil is energized, one end in the longitudinal direction of the armature 9 is attracted to the magnetic pole surface at the end of the iron core 1 according to the direction of magnetization, and the armature block 8 swings. , Iron core 1 → armature 9 → permanent magnet 2 →
A closed magnetic path of the iron core 1 is formed, and a movable contact 10 fixed to a tip 7b of the contact spring 7 on the side of the two contact springs 7 that is attracted to the end of the iron core 1 from the swing center is a body block. The movable contact 10 fixed to the tip 7b of the contact spring 7 on the side opposite to the sucked side is disengaged from the fixed contact 6 by coming into contact with the fixed contact 6 of FIG. When energization of the coil is stopped in this state, the closed magnetic path is maintained as it is by the magnetic force of the permanent magnet 2, and the state in which the armature 9 is in contact with one magnetic pole surface of the iron core 1 is maintained. If the direction of current supply to the coil is reversed, the armature 9 is attracted to the magnetic pole surface at the other end of the iron core 1 and the movable contact 10
Are dissociated, and the movable contact 10 on the opposite side contacts the fixed contact 6. In this state as well, after the energization is stopped, the state is maintained, and a so-called bistable operation is performed. In the above description, the case of the bistable type has been described.
It is also applicable to the monostable type.

した接触が得られなくなる。In the polarized relay having the above structure, the distortion (so-called sag) generated at the end of the armature 9 when the armature 9 is processed, and the side pieces of the armature 9 and the iron core 1 are formed. As shown in FIG. 16 (b), the end of the armature 9 contacts the end of the armature 9 at the time of the normally closed (NC) side return or at the time of the normally open (NO) side operation. Micro gap 12 between side piece 1a of iron core 1
Occurs, and stable contact between the end of the armature 9 and the side piece 1a of the iron core 1 cannot be obtained.

Attraction force acts on the micro gap 12, and as shown in FIG. 16C, the armature 9 moves in the direction of the arrow B in the figure so as to fill the micro gap 12, and at this time, the armature 9
And the side piece 1a of the iron core 1 comes into contact with each other, and there is a problem that clicking noise and a beat occur.

が発生するという問題があった。Also, as shown in FIG. 17, the armature block 8 is mounted on the permanent magnet 2 so as to be swingable by welding the hinge spring pieces 7a to the fixing pieces 4a, respectively. If welding variations occur when welding 7 a, a minute gap may be generated between the armature 9 and the permanent magnet 2 at the fulcrum 13, and a stable gap between the armature 9 and the permanent magnet 2 may be generated. When line contact cannot be ensured, and a reverse voltage is applied continuously to return, for example, at the time of return to the NC side, the armature 9 moves due to the attraction force of the side piece 1a, causing click noise and humming, as described above. There was a problem of doing.

There are also problems that the frictional force with the contact 1a increases, the operating voltage increases, and the reliability of contact between the fixed contact 6 and the movable contact 10 decreases due to generation of wear powder. The same problem occurs during the NO-side operation.

And two contact springs 7 arranged on both sides in the longitudinal direction of the armature 9 are integrally molded by molding with synthetic resin.
As shown in FIGS. 3 (a) to 3 (c), on the surface of the armature 9 facing the permanent magnet 2, projections 9a, 9a, which are minute projections, are provided substantially at the centers of both ends in the longitudinal direction. A ridge 9b running in the width direction is formed at the center. The fulcrum part 13 is a ridge 9
b, and formed portions 8b formed on both sides of the ridge 9b in the width direction of the armature 9. The armature 9 swings on the permanent magnet 2 with the fulcrum portion 13 as a swing fulcrum (seesaw motion). The armature 9 and the permanent magnet 2 are freely mounted, and the fulcrum 1
Since there is line contact at 3, stable contact can be ensured.
When the armature 9 is attracted to one side piece 1a of the iron core 1, the armature 9 and the iron core 1 come into point contact with the projection 9a.
Even if distortion occurs due to processing at both ends in the longitudinal direction of the armature 9, no microgap occurs between the armature 9 and the side piece 1a, and the armature 9 and the side piece 1a of the iron core 1 Contact can be stabilized. Further, by providing the projection 9a at a position where the side piece 1a of the armature 9 is attracted, the gap between the armature 9 and the side piece 1a is widened, and the magnetic flux is concentrated on the projection 9a. Working suction force is reduced.

No clicking noise or beats occur. Further, since the armature 9 does not move, the armature 9 does not wear, and a defect caused by the wear of the armature 9 (increase in frictional force between the armature 9 and the side piece 1a, increase in operating voltage) , Reduced contact reliability of contacts due to abrasion powder, etc.)

間に働く吸引力が小さくなる。The armature 9 is swingably mounted on the permanent magnet 2 with the fulcrum 13 as a swing fulcrum. At the fulcrum 13, the armature 9 and the permanent magnet 2 are located at two positions on both sides of the recess 9e. The contact between the armature 9 and the permanent magnet 2 can be made in a more stable state than when the armature 9 and the permanent magnet 2 are in line contact with each other. Further, a protrusion 9a provided at an end in the longitudinal direction of the armature 9 is a side piece 1a of the iron core 1.
Therefore, even if the armature 9 and the side piece 1a of the iron core 1 are in point contact with each other and distortion occurs due to machining at both ends in the longitudinal direction of the armature 9, the armature 9 and the side piece 1a No microgap is generated between them, and stable contact between the armature 9 and the side piece 1a can be secured. In addition, since the projection 9a is provided at a position where the side piece 1a of the armature 9 is attracted, the gap between the armature 9 and the side piece 1a can be widened, and the magnetic flux concentrates on the projection 9a. Thus, the suction force acting between the gaps is reduced.
