Fig. 1 is a front view showing a polarized electromagnetic relay according to the invention, Fig. 2 is an exploded perspective view of Fig. 1, and Fig. 3 is an exploded perspective view of the coil bobbin 3. FIG. In the figure, 1 and 2 are a slightly U-shaped yoke and a magnetic pole piece, 3 is a coil bobbin wound with a coil 11, and is provided with a through hole 3b and a guide groove 3a, and a groove 3c in the collar on the side of the magnetic pole piece 2. can be expanded as necessary. 4 is an armature, 5 is a hinge spring,
6 is a coil terminal, 7 is a drive card, 8 is a spring block on which a contact spring is mounted, 9 is a box, 10 is a lid, and 12 is a permanent magnet. The coil bobbin 3 is molded from resin, and is press-fitted into a guide groove 3a provided in its body so that the ends of the magnetic pole piece 2 and one piece 1a of the yoke 1 are opposed to each other, and are fixed to the outside of the coil. The magnetic pole piece 2 is positioned so as to cover the
A permanent magnet 12a is held in a space A formed by the faces of the other piece of the yoke facing each other. In addition, a permanent magnet 12 is placed in a groove 3c provided in the collar on the side of the magnetic pole piece 2.
b may be fitted and fixed. Note that before press-fitting the piece 1a of the yoke 1 into the guide groove 3a, the L-shaped hinge spring 5 to which the armature 4 is fixed is fixed to the U-shaped piece 1b of the yoke 1 in advance. The pole element 4 is housed in the through hole 3b provided in the coil bobbin 3.

くしておくことが望ましい。 In order to increase the press-fitting strength, the width and height of the guide groove 3a are made slightly smaller than the width and plate thickness of the magnetic pole piece 2a and yoke 1a to be press-fitted, and in order to crimp the permanent magnet 12. One piece of the yoke 1 that covers the outside of the coil is bent at a slightly acute angle, and the magnetic pole piece is bent at a slightly obtuse angle, and the height of the space in which these pieces are arranged so as to face each other is increased. It is desirable that the thickness of the permanent magnet is slightly larger than the length.
この有極形電磁継電器は平常(不動作)状態に
おいては、永久磁石12bが接極子4に作用する
吸引力及び駆動カード7を介して接点ばねの復帰
力(反抗力)によつて第1図に示す状態にある。 In the normal (non-operating) state, this polarized electromagnetic relay is operated by the attractive force of the permanent magnet 12b acting on the armature 4 and the restoring force (repulsive force) of the contact spring via the drive card 7, as shown in FIG. It is in the state shown below.

動作状態を続け、自己保持を行う。 Next, to explain the operation of the polarized electromagnetic relay according to the present invention, when an excitation current is passed through the coil terminal 6 to the coil 11, the magnetic flux changes from the yoke 1 to the armature 4 to the short gap B to the pole piece 2 to the permanent magnet 12a. →The permanent magnet 1 forms the magnetic circuit of the yoke 1, and the armature 4 itself becomes a negative magnetic material due to the excitation current, giving an attractive force in the normal state.
The armature 4 is attracted to the magnetic pole piece 2 side by the repulsive force acting between 2b and the same polarity, and the contact spring is operated by passing the drive card 7 over the repulsive force of the contact spring provided in the spring block 8. Switching (open →
close). In this state, even if the excitation current of the coil 11 is cut off, this operating state is continued and self-maintained only by the magnetic circuit formed by the permanent magnet 12a held between the yoke 1 and the magnetic pole piece 2.
これを復旧させるには上記と逆方向に励磁電流

じめ選定しておくものである。 In order to restore this, the armature 4 will have a polarity opposite to the operating state by passing an excitation current in the opposite direction to the above, and the permanent magnet 12b provided on the collar of the coil bobbin 3 will connect the different polarities. The attractive force acting and the permanent magnet 1 held in the space A
The armature 4 is restored by the repulsive force acting between the same polarity of the magnetic pole piece 2a and the armature 4 after passing 2b, or the repulsive force of the contact spring 8, and the electromagnetic relay returns to its normal state. . The polarity of the two permanent magnets 12a and 12b is selected in advance so that the magnetic pole piece 2 side has a different polarity and the collar side has the same polarity with respect to the polarity of the armature 4 that is excited by the operating current. It is something.
以上説明したように、本考案の有極形電磁継電
器によれば次のような多大な効果を奏する。 As explained above, the polarized electromagnetic relay of the present invention has the following great effects.

有極電磁継電器を提供することができる。 By arranging two permanent magnets to sandwich the faces of the armature to form a magnetic circuit, and energizing the armature with excitation and recovery currents, repulsive and attractive forces are generated on both sides of the armature. Since the two actuators work simultaneously and synergistically, it is possible to provide a polarized electromagnetic relay that can operate with extremely low power and high sensitivity.
