而して本発明の有極継電器の動作を詳述する。The operation of the polarized relay of the present invention will now be described in detail.

コイル２に電流が流されると、Ｕ字形のヨーク１は例え
ば図示の極性に励磁される。When a current is passed through the coil 2, the U-shaped yoke 1 is excited, for example, with the polarity shown.

これにより前記Ｕ字形のヨーク１の一方の胴側の磁力が
犬となり、アマチュア１０を図示の方向に揺動せしめる
。As a result, the magnetic force on one side of the body of the U-shaped yoke 1 acts as a dog, causing the armature 10 to swing in the direction shown.

これに伴ない一方の可動接点バネ１３の自由端に形成さ
れた可動接点１４が固定接点１５に当接される。Accordingly, the movable contact 14 formed at the free end of one of the movable contact springs 13 comes into contact with the fixed contact 15.

ヨーク１は逆方向に励磁され、前記アマチュア５を反対
方向に揺動し、延いては可動接点１４Ａが固定接点１５
Ａに当接される。Furthermore, when a current is passed through the coil 2 in the opposite direction, the U-shaped yoke 1 is excited in the opposite direction, causing the armature 5 to swing in the opposite direction, and as a result, the movable contact 14A moves to the fixed contact 15.
It comes into contact with A.

ここに永久磁石板５０両端がＵ字形のヨーク１０両脚の
溝３，３Ａに嵌入されているので、前記永久磁石板５と
Ｕ字形のヨーク１との間のギャップを殆ど除去でき、磁
気的損失を僅少とできる。Since both ends of the permanent magnet plate 50 are fitted into the grooves 3 and 3A of both legs of the U-shaped yoke 10, the gap between the permanent magnet plate 5 and the U-shaped yoke 1 can be almost eliminated, reducing magnetic loss. can be made very small.

従ってアマチュア１０の揺動動作を迅速化且つ確実化し
得る。Therefore, the swinging motion of the armature 10 can be made faster and more reliable.

同、本発明の有極継電器においては、第３図に示すよう
に、Ｕ字形のヨーク２０を用い、両側翼２１．２ＬＡに

前記溝２２，２２Ａに第１の永久磁石板２５０両端部を
嵌入し、前記溝２３，２３Ａに第２の永久磁石板２６を
嵌入してもよい。In the same polarized relay according to the present invention, as shown in FIG. Both ends of the first permanent magnet plate 250 are fitted into the grooves 22, 22A so as to be parallel to the central connecting part 21B, which is wound 240 times, and the second permanent magnet plate 26 is fitted into the grooves 23, 23A. Good too.

この時は、アマチュア支持用突起２７゜２７Ａを夫々前
記第１、第２の永久磁石板２５゜２６０中央部−側縁に
突設しておけば、単にアマチュア２８の取付孔２９に挿
入すればよくアマチュア２８の取り付は工程の簡略化乃
至は部品点数の削減等を達成し得る。In this case, if the armature supporting protrusions 27° 27A are provided protruding from the center and side edges of the first and second permanent magnet plates 25° 260, then the armature can be simply inserted into the mounting hole 29 of the armature 28. Attaching the armature 28 can often simplify the process or reduce the number of parts.

３０は前記アマチュア２８に載置された可動接点バネ支
持体で、自由端に可動接点を有する可動接点バネが固着
されている。30 is a movable contact spring support mounted on the armature 28, and a movable contact spring having a movable contact is fixed to the free end.
