コイルを巻回したことを特徴とする。In the electromagnetic relay according to the present invention, a coil assembly is configured by disposing a permanent magnet in the center of a U-shaped iron core around which a coil is wound, and an armature arranged so that both ends are fitted to both magnetic pole portions of the iron core. A hinge spring that causes the armature to perform a tilting motion and a movable contact spring disposed near the armature are integrally fixed by an insulating fixing body to form a movable contact spring block, and a fixed contact portion and an external lead terminal are provided. The coil assembly is fixed to the planted insulator base, and the projection in the center of the pole contacts the one end face of the permanent magnet so that the movable contact spring block can tilt, and the armature tilts. In an electromagnetic relay which serves as a fulcrum of movement and in which the hinge spring is fixed to a part of the external lead-out terminal, a coil spooe in which a winding region is divided into two parts by disposing the permanent magnet in a central part. The primary coil is mainly wound around one winding region of the winding, and the secondary coil is mainly wound around the other winding region.
次に、本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.
第１図は本発明の第１実施例におけるコイルスプールの
斜視図であり、第２図はその断面図である。永久磁石９
を中央部に配置するため、コイルスプール８の巻線部は
中央のつばにより２分割されている。この一方の巻線部
17に一次巻線23を、他方の巻線部18に二次巻線24をそれ
ぞれ巻回している。この場合、コイル端子19,20が一次
側端子、コイル端子21,22が二次側端子となる。FIG. 1 is a perspective view of a coil spool in a first embodiment of the present invention, and FIG. 2 is a sectional view thereof. Permanent magnet 9
Is located in the central portion, the winding portion of the coil spool 8 is divided into two by the central collar. This one winding part
The primary winding 23 is wound around 17 and the secondary winding 24 is wound around the other winding portion 18. In this case, the coil terminals 19 and 20 are primary side terminals, and the coil terminals 21 and 22 are secondary side terminals.
ここで、巻線を片側に片寄らせた場合の吸引力特性に及
ぼす影響について説明する。Here, the influence on the attraction force characteristics when the winding is biased to one side will be described.
第３図（ａ）に本タイプの自己保持形電磁継電器の吸引
力，負荷特性を示す。同図中の実線は、両巻線部には均
等に巻線を巻回した場合の吸引力特性、破線は片側巻き
の場合（第３図（ｂ））の特性を示す。因みに、同図の
左側半分が巻線側の吸引力特性である。片側巻きは両側
巻きに比べると、火巻線側で吸引力の変化量が少なく、
減磁効率が劣っているが、巻線側ではその変化量は約1.
3倍となり、減磁効率ははるかに向上している。Fig. 3 (a) shows the attractive force and load characteristics of this type of self-holding electromagnetic relay. The solid line in the figure shows the attractive force characteristic when the windings are evenly wound on both winding parts, and the broken line shows the characteristic when the winding is unilaterally wound (FIG. 3 (b)). Incidentally, the left half of the figure is the attraction force characteristic on the winding side. Compared to double-sided winding, one-sided winding has less change in suction force on the fire winding side,
The demagnetization efficiency is inferior, but the amount of change on the winding side is about 1.
It has tripled and the demagnetization efficiency is much improved.
なお、自己保持形電磁継電器は、ばね負荷を無励磁時の
吸引力の内側に入れる設計であるため、その感動電圧
は、吸引力が減磁によりばね負荷の内側となった時点で
決まる。すなわち、同図において接極子が同図左側の吸

側の減磁特性だけでその感動電圧は決定し、同図右側の
減磁特性は全く関与しない。すなわち、接極子の閉成し
ている側の片側巻きコイルを用いて接極子を開放する動
作を行わせれば、その感度を約1.3倍とすることができ
る。しかしその逆を行うと、その感度は0.77倍に低下す
ることとなるので注意を要する。Since the self-holding electromagnetic relay is designed to put the spring load inside the attraction force when there is no excitation, the impression voltage is determined when the attraction force is inside the spring load due to demagnetization. That is, in the same figure, when the armature shifts from the attraction state on the left side of the figure to the attraction state on the right side of the figure, the sensing voltage is determined only by the demagnetization characteristic on the left side of the figure. Not involved at all. That is, if the operation of opening the armature is performed using the one-sided coil on the closed side of the armature, the sensitivity can be increased by about 1.3 times. However, if the opposite is done, the sensitivity will decrease by 0.77 times, so be careful.

次に第４図（ｂ）に示すように第二次コイル24の大半を
巻線部18に巻回してから、残りを巻線部17に巻回するも

Next, as shown in FIG. 4B, most of the secondary coil 24 is wound around the winding portion 18, and the rest is wound around the winding portion 17.
以上説明したように本発明は、巻線部が二分割されたコ
イルスプールの一方に第一次コイルを、他方に第二次コ
イルを巻回することにより、以下の効果が得られる。As described above, according to the present invention, the following effects can be obtained by winding the primary coil on one side of the coil spool whose winding portion is divided into two and the secondary coil on the other side.
（１） 第一次，第二次コイルともに同一線径の線材を
使用できるため、巻線コストを低減できる。(1) Since the wire material having the same wire diameter can be used for both the primary coil and the secondary coil, the winding cost can be reduced.
（２） 減磁効率が向上するため、より高感度な電磁継
電器を提供できる。(2) Since the demagnetization efficiency is improved, an electromagnetic relay with higher sensitivity can be provided.
