に、大きな励磁電流が必要となる。Conventional polarized electromagnetic relays include hinge-type relays in which one end of an armature (movable iron piece) is pivoted at the outer end of an excitation winding. In this relay, the movable iron piece is attracted by the magnetomotive force of the excitation winding that resists the spring force of the hinge spring, but a large excitation current is required due to the magnetic gap and frictional resistance of the hinge part of the movable iron piece. becomes.

て調整することができない。In addition, an armature is passed through the hollow part of the excitation winding so that both ends of the armature are exposed, and at the end of the armature there are two roughly U-shaped magnets magnetized with different polarities by permanent magnets. The end of the armature is disposed between opposing magnetic poles of different polarity, which are formed by arranging the ends of the yoke to face the permanent magnet in the normal plane. There are also polarized electromagnetic relays that support However, in this relay, when the two yokes and the permanent magnet are fixed, the gap between the opposing magnetic poles of the two yokes is fixed as well as fixed, so the moving distance of the armature (f+-mature travel) cannot be adjusted due to this fixation error.

に移動距離の調整後の保持を成せる。As explained above, according to the present invention, by using two yokes whose tips are bent at right angles and a permanent magnet having magnetic poles on opposite sides, the permanent magnet can extend over the entire length of the excitation winding. Since a large size can be used, the magnetic attraction force can be increased. In addition, it is possible to easily construct a garden by stacking the constituent members one after another. Furthermore, since the moving distance of the armature is determined by the distance between the opposing portions of the two yokes that are bent at right angles, the amount of movement can be easily adjusted by shifting one of the yokes in the vertical direction. At this time, if a spacer or the like is inserted between the lower end of the yoke and the winding frame, the movement distance can be held even more reliably after adjustment.
