First, when a voltage is applied to the coil terminal 13 and the drive coil 12 is energized, the substantially U-shaped iron core 11 is magnetized, and the magnetic armature 9 is attracted to the substantially U-shaped iron core 11. For this reason, the movable contact spring 6 is driven via the card portion 8 to bend or loosen the arcuate portion 14, and finally the movable contact 5 is operated from the fixed contact 3a to the fixed contact 3b.

ことができる。According to the above-described electromagnetic relay, since all the electromagnetic blocks such as the fixed contact terminal plate 2, the movable contact terminal plate 4, the plastic spring portion 7, the magnetic armature 9, and the spool 10 can be formed in a substantially plate shape, the ultra-thin shape is achieved. In addition, the weight can be reduced, and the productivity can be improved by integrating the base 1 and the plastic spring portion 7.

に適したリレーを提供することができる。Moreover, in this electromagnetic relay, the armature travel (moving distance of the magnetic armature 9) is increased by providing the movable contact spring with the arcuate portion 14 and performing a snap action when operated by the card 8. As a result, a large contact gap can be realized, and an electrical switching capacity can be increased, that is, a relay suitable for a large current can be provided.

For this purpose, a laminated piezoelectric actuator 18 and an electrode 19 for supplying a drive current thereto are provided. The movable contact spring 6 has an arcuate portion 14 having a step operation function, and engages with a second fulcrum 17 on the upper part of the plate-shaped movable contact terminal plate 4.
The laminated piezoelectric actuator 18 is sandwiched between the third fulcrum 20 and the first fulcrum 16, and is mechanically engaged with the L-shaped end on the upper part of the movable contact terminal plate 4. Since the laminated piezoelectric actuator 18 is connected to the electrode 19 and can be easily formed into an elongated and arbitrary shape, the thin piezoelectric actuator 18 and the movable contact terminal plate 4 can be easily formed.
The structure is such that mechanical engagement with the device can be facilitated.

を大幅に軽減することになる。Next, the operation of the electromagnetic relay of the embodiment will be described. First, when a voltage is applied almost simultaneously to the electrode 19 and the coil 12 of the electromagnetic block, the laminated piezoelectric actuator 18 contracts, and the force applied to the arcuate portion 14 of the movable contact spring 6 is reduced. Becomes larger. Since the spring reversal force due to the pressing of the driving point of the movable contact spring 6 in such a state is reduced, the driving power of the relay is greatly reduced.

向上することになる。Next, after the movable contact 5 comes into contact with the fixed contact 3b, the voltage application to the electrode 19 is released. As a result, the pressure of the arcuate portion 14 is increased again, and the contact contact force increases. That is, the contact chatter is suppressed and the contact stability is improved.

As shown in FIG. 3, the laminated piezoelectric actuator 18 expands and contracts depending on the polarity and magnitude of the applied voltage.

り、駆動電力が小さくて済む。However, if the bow portion 14 is greatly bent, the driving force of the plastic spring portion 7 and the card portion 8 for inverting the movable contact spring 6 becomes excessive. Therefore, when the movable contact spring 6 is reversed, the arcuate portion 14 is extended, that is, the laminated piezoelectric actuator 18 is contracted and driven by the card portion 8. With such driving, the driving power can be reduced.

By applying the voltage to the electrodes, it expands or contracts), or by combining the timing of applying the voltage to the electrode with the timing of applying the voltage to the coil,
Sensitivity can be further increased, and a low holding voltage and low open voltage relay can be realized.
