[Background Art] Conventionally, an electromagnetic relay disclosed in European Patent Publication No. 62332 has been known. This electromagnetic relay has a pair of yokes spaced apart from each other and arranged parallel to the axis of the coil, and a permanent magnet is interposed between the two yokes to excite the two yokes to different magnetic poles. A magnetic pole surface is formed at one end of both yokes, and the armature is arranged so as to be swingable between two positions in which one end abuts each magnetic pole surface. In the monostable electromagnetic relay disclosed in the above European patent, the other end of the armature is supported by a paramagnetic support provided at the other end of one of both yokes. If the above configuration is to be bistable, paramagnetic supports are formed at the other ends of both yokes,
The other end of the armature is supported between the surface supports.

In the case of a bistable type, the paramagnetic armature is connected to both yokes via the paramagnetic support at the supporting end of the armature, so there is no intervening space between the two yokes. A problem arises in that the two magnetic poles of the installed permanent magnet are magnetically short-circuited by the armature.

(Operation) The operation will be explained below. In Fig. 1, armature 1
6 is located at the center position between both terminal positions during swinging, that is, at a position where the armature 16 passes only during the swinging process, and in FIG. It shows the location of the terminal. In the position shown in FIG. 2, the contact piece 22 of the movable contact spring 20 contacts the contact piece of the fixed contact 24, and the contact device is closed. In the position shown in FIG. 2, the armature 16 is held by the magnetic force of the permanent magnet 26.
Pole-inner yoke 27-support 17-armature 16-magnetic pole piece 3
A closed magnetic path is formed from the magnetic pole surface 33 of No. 1 to the outer yoke 29 to the S pole of the permanent magnet 26. From this state, coil 1
When the armature 16 is energized so that the free end of the armature 16 becomes the S pole and the end of the armature 16 becomes the N pole, the free end of the armature 16 becomes the magnetic pole piece 31. Since the armature 16 is repelled by the magnetic pole piece 30 of the outer yoke 28 and is attracted by the pole piece 30 of the outer yoke 28 having the opposite polarity, the armature 16 moves to the opposite terminal position from that shown in FIG. When the current to the coil 12 is stopped, the armature 16 is held at its terminal position by the magnetic force of the permanent magnet 25. Since the movable contact spring 20 is simultaneously driven by the card 18 when the armature 16 is reversed, the contact piece 22 of the movable contact spring 20 comes into contact with the contact piece of the fixed contact 23 .

次にコイル12に逆向外の電流が通電されると、接極子
16は再び第2図に示された位置に復帰する。
When the coil 12 is then energized with a reverse current, the armature 16 returns to the position shown in FIG.

As mentioned above, the magnetic forces of both permanent magnets 25, 26 act at each terminal position during the reversal operation of the armature 16, and at the beginning of the reversal operation, the magnetic force of both permanent magnets 25, 26 is magnetically coupled to it by one of the permanent magnets. A repulsive force created through the pole piece acts between the armature 16 and the pole piece, and at the end of the reversal action an attractive force created through the pole piece magnetically coupled to it by the other permanent magnet is brought into contact. It acts between the pole piece 16 and the pole piece. After the coil 12 is de-energized at each terminal position of the armature 16, the holding force of the armature 16 is generated only by the magnetic force of one of the permanent magnets 25, 26, and is magnetically coupled to the other permanent magnet. Since the air gap between the pole piece and the armature 16 is relatively large, the repulsive force produced by the other permanent magnet is negligible.

In addition, even though such high magnetic efficiency is obtained, no magnetic short circuit occurs in the permanent magnets 25, 26 at any of the terminal positions.

In FIGS. 1 and 2, the magnetic forces of the permanent magnets 25 and 26 are made equal, and both outer yokes 28f29, inner yoke 27, and both permanent magnets 25 and 26 are aligned with the axis of the coil 12 and the center line of the inner yoke 27. Since it is formed symmetrically with respect to a plane containing , in this case, the above-mentioned bistable operation is performed.

In the case of monostable operation, one of the permanent magnets 25 and 26 should be replaced with a member made of paramagnetic material, or one of the outer yokes 28 and 29 and the armature 16 should be directly coupled magnetically. For example, it can be realized without changing the configuration.

[Effects of the Invention 1] As described above, the present invention includes a coil frame in which a coil is wound and an insertion hole passing through the coil in the axial direction, and a connector that is swingably inserted into the insertion hole of the coil frame. A pole, a contact device that is driven to open and close as the armature swings, and a magnetic pole surface that is arranged at a distance from each other and abuts one end of the armature at each terminal position of the armature's swing range. a pair of outer yokes, an inner yoke disposed between both outer yokes, and a permanent magnet interposed between at least one of the outer yokes and the inner yoke to excite both outer yokes to different polarities. The other end of the armature is pivotally supported by a support that is magnetically coupled to the inner yoke. According to this configuration, during the course of swinging, the armature is not magnetically coupled to either of the pair of outer yokes that have a magnetic pole surface that can come into contact with one end that is the free end of the armature. Also,
Pivot side end of armature 1. t1 is magnetically coupled to an inner yoke that separates a pair of permanent magnets disposed between both outer yokes and magnetized on the same inner and outer sides. Therefore, there is an advantage that short-circuiting of the permanent magnets is avoided. Furthermore, it has the advantage that the magnetic coupling to the support at the end of the armature on the pivot side can be effected without increasing the magnetic resistance. At each terminal position, the attractive force acting on the armature, that is, the holding force due to the magnetic force of the permanent magnets, is generated only by the magnetic force of one of the permanent magnets. To cause the armature to reverse motion, the magnetic flux generated by the coil and the magnetic flux of the permanent magnets act together, and in this case, one permanent magnet exerts a repulsive force on the armature, and the other permanent magnet Magnets exert an attractive force.
