Abstract

PURPOSE:To obtain a relay having a small operation current and an operating electromagnet device with good balance by providing a repelling spring on a link which carries out the making and breaking of a movable contact in association with a plunger of the operating electromagnet device. CONSTITUTION:A repelling spring 30 supported by a supporting pin 13 of a link 12 serves to press the link 12 so as to pinch it. With this construction, in the 'on' state, the spring 30 does not give the link 12 a revolving force, while in the off state, one end 30c abuts on the internal surface of a base, and thereby the spring 30 is pushed downward. One end 30a energizes the link 12 to turn in the direction of arrow B. This force makes a plunger 5 move in the direction of arrow A and becomes a repelling force which reduces the attraction of the plunger 5. Accordingly, an electromagnet device having a good balance in its attraction at the time of ON and OFF operation is obtained and also a relay having a small operation current is obtained.

Figure 5 shows a state in which the remote control relay is OFF. In this state, as shown in Figure 5, due to the magnetic flux of the permanent magnet (9), the plunger (5) has its attraction surface (5a) attached to the first yoke ( 8) is held in an adsorbed state on the bottom of the
In this main circuit open state, the control circuit terminal (2
When the ON operation switch (not shown) connected to 4) is turned on and the electromagnetic coil (6) is energized, the attraction force by the permanent magnet (9) on the plunger attraction surface (5a) is reduced, and the other Magnetic flux is generated to increase the attraction force on the attraction surface (5b). As a result, the plunger (5) is driven in the direction of the arrow in FIG. 6, the movable contact (11) is pushed down by the link (12) toward the fixed contact (21), and the main circuit is closed. In this state, the suction surface (5b) of the plunger (5) is suctioned and held on the upper surface of the first yoke (8). At this time, the operating lever (28) rotates clockwise in conjunction with the plunger (5), and the display shows rOFF.
Changes from J to “ON”. During this series of operations, the operating lever (28) operates the actuator (26a) of the control circuit switch (26), and the control circuit switch (26) operates.

On the other hand, when the OFF operation switch is turned on in this main circuit closed state, the electromagnetic coil (6) reduces the attraction force of the permanent magnet (9) on the plunger attraction surface (5b),
Magnetic flux is generated in a direction that increases the attraction force on the other attraction surface (5a). As a result, the plunger (5) is driven in the direction of the arrow in Fig. 5, and the movable contact (1) is driven by the link (12).
1) is separated from the fixed contact (21). This causes the main circuit to become open. This state is plunger (5)
This is an initial stable state in which the suction surface (5a) of is suctioned to the bottom surface of the first yoke (8). At this time, the operating lever (28
) rotates counterclockwise in conjunction with the plunger (5) to change the display from "ON" to "rOFF" and at the same time also switches the control circuit switch (26).

The operation in this case is to manually apply a peeling force greater than the suction force of the plunger (5) directly to the plunger (5) to forcibly remove the suction and bring it to another stable state. The movement of the movable contact portion (15) and the operation of the control circuit switch (26) at this time are exactly the same as the series of electrical operations described above.

[Problems to be Solved by the Invention] The operation of the polarized electromagnet device involves passing an operating current through the electromagnetic coil, thereby canceling out the magnetic flux caused by the permanent magnet on the attracting surface.
The purpose of this is to reduce the adsorption force and release the plunger. In the conventional remote control relays like those mentioned above, in the ON state, the contact pressure of the contacts acts as a repulsive force and reduces the adsorption force on the adsorption surface, but in the OFF state, In this state, there is no force equivalent to this repulsive force, and the adsorption force is large. Therefore, the operation current is also larger in the ON operation than in the leaf F operation, and there are problems in that the operation current becomes large as a remote control relay.
