【考案の詳細な説明】 （産業上の利用分野） 本考案は電磁継電器、特に、その内部に組み込まれる電
磁石装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an electromagnetic relay, and more particularly to an electromagnet device incorporated therein.
（従来技術と考案が解決しようとする課題） 一般に、電磁継電器においては電磁石装置の占有スペー
スが大きいので、電磁継電器を小型化するためには電磁
石装置をいかに小型化するかが問題となる。(Problems to be Solved by Prior Art and Invention) Generally, in an electromagnetic relay, an electromagnet device occupies a large space. Therefore, in order to downsize the electromagnetic relay, how to miniaturize the electromagnet device becomes a problem.
従来、電磁継電器に組み込まれる電磁石装置としては、
例えば、第５図に示すように、断面長方形の板状材を板
厚方向に折り曲げ、両端部を磁極部2,3とした平面略コ

長方形の鉄芯５とからなるものがある。Conventionally, as an electromagnet device incorporated in an electromagnetic relay,
For example, as shown in FIG. 5, a plate-shaped member having a rectangular cross section is bent in the plate thickness direction, and a yoke 1 having a substantially U-shape in plan view with both end portions having magnetic pole portions 2 and 3 and a coil winding portion 5a has a coil. 4 is wound and the cross-section is made vertically long, and one end is fixed to the center of the inner surface of the yoke 1 by caulking, so that the other end is a magnetic pole part 6 facing the magnetic pole parts 2 and 3 of the yoke 1. There is a core having a rectangular cross section.
そして、第６図に示すように、永久磁石７を一対の可動
鉄片8a,8bで正面略コ字形状に挾持したものを、前記鉄
芯５の磁極部６に馬乗り状態に配し、かつ、水平方向に
往復移動可能に支持していた。Then, as shown in FIG. 6, a permanent magnet 7 held between a pair of movable iron pieces 8a, 8b in a substantially U-shape on the front is arranged on the magnetic pole portion 6 of the iron core 5 in a horse riding state, and It was supported so that it could move back and forth horizontally.
したがって、前記コイル４を励磁，消磁することによ

の磁極部2,3に交互に接離し、水平方向に往復移動して
図示しない電磁継電器の接点機構部を駆動する。Therefore, when the coil 4 is excited and demagnetized, the movable iron pieces 8a, 8b cause the magnetic pole portion 6 of the iron core 5 and the yoke 1 to move.
The magnetic pole portions 2 and 3 are alternately contacted and separated, and reciprocally move in the horizontal direction to drive a contact mechanism portion of an electromagnetic relay (not shown).
しかしながら、従来例にかかる電磁石装置は、ヨークと
ほぼ同等の高さ寸法を有する鉄芯５全体を断面縦長に配

と、嵩高くなり、コイル４がヨーク１の上下端面からは
み出し、電磁継電器の薄型化は困難であるという問題点
があった。However, in the electromagnet device according to the conventional example, the entire iron core 5 having a height dimension almost equal to that of the yoke is arranged in a longitudinally long cross section. Therefore, when the coil 4 is wound around the coil winding portion 5a, it becomes bulky. The coil 4 protrudes from the upper and lower end surfaces of the yoke 1, which makes it difficult to reduce the thickness of the electromagnetic relay.
このため、第７図および第８図に示すように、鉄芯５全

で、電磁継電器を小型化できないとともに、磁極部６の
吸着面積が狭くなるので、磁気効率が悪いという問題点
があった。For this reason, as shown in FIGS. 7 and 8, it has been proposed to fix the entire iron core 5 by making the entire cross-section laterally long and crimping it, but since the permanent magnet 7 becomes wider and the floor area increases, There is a problem that the electromagnetic relay cannot be downsized and the magnetic attraction area of the magnetic pole portion 6 is narrowed, so that the magnetic efficiency is poor.

たものである。(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a substantially E-shaped plane in which one end of a rectangular iron core is fixed to the central portion of the inner side surface of a substantially U-shaped plane yoke. Based on the excitation and demagnetization of the electromagnet device having the other end portion as the magnetic pole portion, a pair of movable iron pieces sandwiching the permanent magnet so as to have a substantially U shape are alternately provided on both side surfaces of the magnetic pole portion of the iron core. In an electromagnetic relay that drives a contact mechanism section in a movable block that reciprocates in the horizontal direction by adsorbing and separating, the iron core is arranged in a laterally long section, and
The center of the cross section is shifted downward from the vertical center line of the yoke and fixed, and the permanent magnet is arranged above the magnetic pole portion of the iron core so as to be in a horse riding state.

いても、永久磁石48の磁力により、その状態が保持され
る。Then, the coil 34 is arranged so as to cancel the magnetic flux of the magnetic circuit.
When a voltage is applied to and excited by the movable iron pieces 46 and 47,
The movable block 40 moves in the direction of the arrow P ′ and switches the contacts because the magnetic blocks 36 and 33 repel each other and are attracted to the magnetic poles 36 and 33 respectively. The state is maintained by the magnetic force of 48.
ついで、コイル34に対して前述と逆方向の電圧を印加す

長になっているので、コイル34を巻回しても嵩高くなら
ず、薄型の電磁継電器を得ることができる。According to the present embodiment, since the coil winding portion 35a of the iron core 35 has a laterally long cross section, winding the coil 34 does not make it bulky, and a thin electromagnetic relay can be obtained.
また、鉄芯35の磁極部36を断面縦長にしてあるので、可
動ブロック10が巾広とならず、電磁継電器の床面積が小
さくなるとともに、磁極部36の吸着面積が広くなるの
で、磁気効率が良くなる。Further, since the magnetic pole portion 36 of the iron core 35 has a vertically long cross-section, the movable block 10 does not become wide, the floor area of the electromagnetic relay becomes smaller, and the attracted area of the magnetic pole portion 36 becomes wider, so that the magnetic efficiency is improved. Will get better.

られるという利点がある。Furthermore, the center of the cross section of the iron core 35 is the vertical center line A of the yoke 31.
Since the position is shifted by δ from -A to the lower side, no unnecessary gap is created between the lower end surface of the wound coil 34 and the lower end surface of the yoke 31, and the movable block 40 is lower than in the conventional example. There is an advantage that positioning can be performed and a thinner electromagnetic relay can be obtained.

形状を有するものであってもよいことは勿論である。In the above-mentioned embodiment, the case where the magnetic pole portion 36 of the iron core 35 is twisted at a right angle to have a vertically long cross section is described, but the invention is not limited to this, and may be integrated by welding, press working or sintering. May be shaped. Further, it is needless to say that the yoke is not limited to the one having a substantially U-shaped shape in a plane, but may be, for example, one having a substantially L-shaped shape in a plane.
（考案の効果） 以上の説明から明らかなように、本考案によれば、断面

ヨークの上下端面からはみ出さず、電磁石装置が嵩高に
ならず、電磁継電器を薄型化できる。(Effect of the Invention) As is apparent from the above description, according to the present invention, the coil winding portion of the iron core having a rectangular cross section is arranged in the laterally long cross section. Therefore, the coil is wound around the coil winding portion. However, the coil does not protrude from the upper and lower end surfaces of the yoke, the electromagnet device does not become bulky, and the electromagnetic relay can be made thin.
しかも、鉄芯の断面中心をヨークの上下中心線よりも下
