Explained by. An exciting coil 10 is wound on a hollow bobbin (not shown in FIG. 3). The armature 20 is held by a yoke 21 on one end side of the bobbin, with one end (not shown) as a rotatable shaft. The open end of the amateur 20 has a fixed magnet depending on the direction of the current flowing through the coil.
It moves between magnetic poles 22 and 23 which are magnetized by 24.
This moving operation moves the card 25 in the direction of the arrow shown in FIG. The card 25 is provided with a notch 26 in a direction perpendicular to its moving direction. On the other hand, the leaf spring 1 has one end
1-S is fixed, and movable contacts 5 not shown in these figures are provided on the opposite sides of the open end 1-O on the opposite side. Fixed contacts 6 (not shown) are provided on the fixed terminals 30 so as to face both the movable contacts. The notch 26 provided in the card 25 is arranged at an appropriate position in the middle of the length of the leaf spring 1 so as to surround the front and back of the leaf spring 1 as shown in FIG. Therefore, the leaf spring 1 is driven by the card 25 in the bending direction of the leaf spring, that is, the thickness direction thereof, so that the movable contact 5 is brought into contact with or released from the fixed contact 6.

Taking the above-mentioned polarized relay as an example, the relationship between the moving distance (hereinafter referred to as the stroke) of the card, that is, the leaf spring, and the force required to push it, that is, the load, is shown by the dotted line in FIG. The part where the load is horizontal in the center part of the stroke indicates the unloaded part of the gap between the card and the leaf spring, and the dotted line overlaps the solid line part. The inclination after the gap is closed at the point K 0 indicates the elastic coefficient of the leaf spring 1 with the tip open. After the movable contact contacts the fixed contact 6 at K'and K '', the leaf spring 1 is fixed at both ends, so that its elastic coefficient becomes large and the inclination becomes steep. On the other hand, the attraction force characteristics (hereinafter referred to as driving force) due to the bidirectional currents flowing through the coil are shown by the dotted curves A and A'in FIG. 14, respectively.

ンの削減、即ち消費電力の削減に限界があった。Reducing the power consumption of the relay, that is, reducing the ampere-turn of the coil, is to make this driving force curve as close to zero as possible. There is a condition that the driving force curve and the load curve must not come into contact with each other. However, in the conventional electromagnetic relay described above, there is a risk that these curves come into contact with each other near the points indicated by K ', K''or T. Therefore, there is a limit to the reduction of ampere-turns, that is, the reduction of power consumption.

Indicates the inclination by the elastic coefficient determined by the distance d between the fixed point of the leaf spring and the pressing point P. When the stroke is further advanced as shown in FIG. 1 (c), the load becomes large due to the elastic coefficient at the two-point support of the movable contact 5 and the fixed point of the leaf spring,
The load curve increases in slope as shown by. When the stroke of the card is further advanced by the difference ΔH in height between the first and second driving means 7 and 8 from the k 1 point, the card is used as the second driving means at the point k 2 as shown in FIG. 1 (d). The shoulder 8 at the tip contacts the leaf spring. After that, as a result, the distance between the second pushing point Q and the movable point becomes smaller, the elastic coefficient of the leaf spring becomes larger, and the load curve further inclines as shown by. That is, the number of the break points K of the load curve is increased, and the inclination is increased near the end point of the stroke.

なる。The operation will be described with reference to the progress chart of FIG. 12 and the load curve shown by the solid line in FIG. Before the card stroke starts, the gap between the tip 7-2 and the leaf spring 1'is represented by ΔG,
After that, the stroke is started, but the state where the stroke is not yet touched is shown by G in FIG. After the tip end 7-2 contacts the tongue piece 1-3 at the point K 0 , the state in which the tip 7-2 is further pressed during the stroke ΔJ of the contact gap is shown in FIG. At this time, the length of the protrusion 7-2 is 0.5
mm is less than 1.1 mm distance between two separating pieces, so tongue 1-
Press only 3 and do not touch the separating pieces 1-1 and 1-1 '. After that, the movable contact 5 comes into contact with the fixed contact 6 at the point k 2 in FIG. 13 as shown in FIG. There, the tongue piece 1-3 is narrower than the separating pieces 1-1 and 1-1 'of the leaf spring and has a smaller elastic coefficient, which is good. Eventually, the shoulder 8-2 will separate the leaf springs 1-1, 1-1 'other than the tongue 1-3.
To contact. The state is shown in Fig. 12 (d). At this time, not only the shoulder 8-2 on the open end side of the leaf spring but also the shoulder 8-2 'on the fixed end side
Can also be brought into contact with the leaf spring. Similarly to the load curve of the first embodiment, the load curve of FIG. 13 goes through many break points and the load increases with the stroke. This third
At the bending point K 2 , the curved shoulder portion 8-2 sequentially contacts the leaf spring from near the protrusion 7-2, and thus the bending point becomes a curved shape.

In the load curve of the present invention, although the width of the driving force curves A and A ′ necessary for driving the relay is reduced, that is, the driving force difference required for operation and recovery, the contact between the load curve and the driving force curve is reduced. It turns out that there is no anxiety.
