In the figure, 47 is a buffer spring, 48 is a blind plate, the buffer spring 47 is used to press and fix the electromagnet device 4 housed in the body 1, and the blind plate 48 is used to store additional parts in the body 1. It is used to cover the opening 1d of the chamber IC.

This relay operates as follows.

The states shown in FIGS. 2, 4, and 6 are states in which the main contact mechanism is turned off. In this state, neither of the armatures 11a and llb is excited, and the movable piece 5 moves backward, so that both ends of the armature 11a are connected to the magnetic yokes 8, 8, which are excited to the north pole by the permanent magnet 7. Both ends of the armature 11b are attracted to the rear end of the yoke 9, which is excited to the south pole by the permanent magnet 7. The attraction force by the permanent magnet 7 is shown by curve A in Fig. 8.
As shown, the closer the movable piece 5 is to the ON position, the larger it becomes in the ON direction, and the closer the movable piece 5 is to the OFF position, the larger it is in the OFF direction. The rocking body 25 is in a state in which the lower end is pulled by the movable body 5 and retreats, and the upper end moves forward. The support part 32 protrudes ahead of the support part 33, and the movable contact 37, which is biased backward by the contact pressure spring 36, has its upper end pressed against the support part 32 and its lower end pressed against the stopper 1b. Therefore, the contact pressure spring 36 rotates the movable contact 37 using the stopper 1b as a fulcrum, pushes the support part 32, and pushes the movable piece 5.
It is urging the movement forward. The load due to the contact pressure spring 3G of the popular hot water table near the position where the movable piece 5 is OFF is as shown by the broken line B in FIG. In the OFF position, the attraction force by the permanent magnet is applied to the contact spring 36.
The movable body 5 remains in the OFF position. The actuator section 27 pushes up the tip of the contact spring 20b to separate the contacts 22, 22 of the contact spring 20b and the contact 21 of the contact plate 19a. On the other hand, the contact 22°22 of the contact spring 20c and the contact 2 of the contact plate 19b
1 remains in contact.

In the above state, when an ON signal current is passed from the operation circuit to the relay circuit in the direction of arrow C as shown in FIG.
b, contact plate 19b, contact spring part 20. Coil 10. It flows with the terminal plate 14. Then, as shown in FIG.
b are respectively excited to the S pole. As a result, the armature 11a
The magnetic flux between the front ends of the yokes 9 and 9 and between the armature 11b and the rear ends of the magnetic yokes 8 and 8 increases,
and between the front ends of the magnet yokes 8, 8 and the armature 11b.
Then, the magnetic flux at the rear end of the yoke 9.9 decreases, and depending on the position of the movable body, an attractive force due to the magnetic force as shown at D in FIG. 8 is generated. As a result, the force for moving the movable body 5 forward increases, and the movable body 5 moves forward due to the total force of the magnetic attraction force and the spring driving force. When OFF, contact spring 3
6 urges the movable body 5 to move forward, the ON signal current voltage (operating voltage) applied to the coil 5 can be low. Further, as will be explained later, since the OFF current voltage applied to the coil 5 can be lowered, the ON and OFF signal current voltages can be lowered to improve the sensitivity of the relay. On the other hand, when the movable contact 3
If there is no stopper that can be applied to the tip of movable body 5,
If no load is applied to move it forward, it will be necessary to increase the operating voltage, which will reduce the sensitivity. In other words, in this relay,
A stopper 1 is provided on the back surface of the movable contact 37 in the body 1.
b is provided, or when it is not provided, the attraction force curve needs to be, for example, like the curve shown by the broken line in the figure. However, as mentioned above, the position of the movable contact 37 when it is OFF is at the stopper lb.
Since the position is held by
The suction force is small as shown by the curved line in the figure. Therefore, the operating voltage can be reduced.

As the movable body 5 moves forward, as shown in FIG.
The rocking body 25 rotates so that its upper end moves backward and its lower end moves forward. Then, the support part 33 pushes the middle part of the movable contact 37, pushes the contact 38 of the movable contact 37 against the contact 43 of the terminal 41, and closes the main contact mechanism. A little later, the actuator portion 27, which has been lowered by the rotation of the movable body 25, pushes down the tip of the contact spring 20c, separating the contact 21 of the contact plate 19b and the contact 22, 22 of the contact spring 20c. During this time, the tip of the contact spring 20b that had been pushed up by the actuator section 27 is lowered, and the contact 2 of the contact spring 20b is lowered.
2.22 and the contact 21 of the contact plate 19a come into contact again, and the direction of the current that can flow through the electromagnet device is switched. Therefore, after the main contact mechanism is closed, the ON signal current is cut off with a slight delay. As will be explained later, in this relay, even after the OFF signal current is applied and the main contact mechanism is opened, the OFF signal current is cut off with a slight delay. In this way, using the auxiliary contact mechanism, the coil 1
If 0 is instantaneously excited, less power is consumed, and since the coil 10 only needs to be instantaneously rated, it can be small, and the entire relay can be made smaller. Moreover, the number of burnout accidents of the coil 10 is reduced.

While the movable body 5 is moving forward, as shown in FIG.
A movable contactor 37 is applied to both of the two, and the contact pressure spring 36 is
The movable body 5 is no longer biased in either forward or backward direction. However, as shown in FIG.
When the movable contact 37 moves forward to the position shown in FIG. As a result, the movable body 5 is urged to retreat.

Furthermore, the contact pressure spring 36 presses the contact 38 of the movable contactor 37 against the contact 43 using the support portion 33 as a fulcrum, so that the contact 38 is strongly pressed against the contact 43.

When the movable body 5 is near the ON position, the load applied to the contact pressure spring 36 in the direction of retracting the movable body 5 is as shown by the polygonal line E in FIG. As shown in this figure, O
At the N time, the attractive force in the ON direction due to the magnetic force applied to the movable body 5 is larger than the load in the opposite direction due to the contact pressure spring 36. Therefore, the movable body 5 overcomes the load of the contact pressure spring 36 and moves forward to the ON position. In addition, even if the ON signal current is cut off, the attraction force in the ON direction by the permanent magnet is greater than the load by the contact pressure spring 3G, so the movable body 5
is held in the ON position.

As shown in Figures 1, 5 and 7
1. When the main contact mechanism is closed, the OFF signal current is opposite to the ON signal current as shown in Figure 7.
When a signal current is applied, this current flows through the terminal plate 14 and the coil 10.
．． Contact spring part 20. Contact plate 19a.

The current flows through the diode 16a and the terminal plate 15. Then,
As shown in FIG. 5, the armature 11a is excited to the S pole, and the armature 11b is excited to the N pole, and an attractive force as shown at F in FIG. 8 is generated depending on the position of the movable body. As a result, the force for retracting the movable body 5 increases, and the movable body 5 retreats due to the total force of the attractive force due to the magnetic force and the spring driving force. Since the contact pressure spring urges the movable body 5 to retreat when it is ON, the OFF signal current voltage applied to the coil 5 is also low.

When the movable body 5 retreats, as shown in FIG.
The rocking body 25 rotates so that its upper end moves forward and its lower end moves backward. Then, the contact pressure spring 36 moves the lower end of the movable contact 37 backward, so that the contact of the movable contact 37 and the contact 43 of the terminal 41 are separated, and the main contact mechanism is opened. A little later, the actuator section 27, which has risen due to the movement of the movable body 25, pushes up the tip of the contact spring 20b, and the contact plate 19b
The contact 21 of the contact spring 20b and the contact 22.22 of the contact spring 20b are separated. During this time, the tip of the contact spring 20c, which had been pressed down by the actuator section 27, rises, and the contact 22.22 of the contact spring 20c and the contact 21 of the contact plate 19b are separated. come into contact again, and the direction of the current that can flow through the electromagnetic device is switched. Therefore, after the main contact mechanism is closed, the OFF signal current is cut off with a slight delay.

In this embodiment, since the terminal 41 is used in the main contact mechanism, even if a large current such as a short circuit current flows, the contact 38 of the movable contact 37 and the contact 43 of the terminal 41 that are in contact with each other This eliminates the possibility that the wire will open due to electromagnetic repulsion, and the short-circuit resistance increases, resulting in excellent short-circuit resistance. This is due to the same reason.

In the conventional contact mechanism, a fixed terminal (fixed contact plate) 49 and a movable contact 50 are combined as shown in FIG. The fixed terminal 49 has an L-shaped portion 49a at the lower end, a contact 51 is provided on the outer surface of the lower end of the L-shaped portion 49, and an electromagnetic iron piece 52 having a U-shaped portion at the bent portion is attached to the L-shaped portion 49a at the U-shaped portion. is inserted and fixed. The movable contact 50 has an electromagnetic iron piece 53 and a contact 54 fixed to the lower end thereof, arranged vertically. and,
The lower part of the L-shaped part 49a of the fixed terminal 49 and the lower part of the movable contact are arranged such that their tips face the same direction in the closed state, and the contacts 51, 54 and the electromagnetic iron pieces 52, 53 are made to correspond to each other, respectively. They are facing each other. The electromagnetic iron piece 52 is excited by the current flowing through the fixed terminal 49 and attracts the electromagnetic iron piece 53. As a result, the contact 54 comes to be strongly pressed against the contact 51. However, for example, when current flows from the terminal 49 to the movable contact 50, the direction of the current flowing through the lower part of the L-shaped portion 49a of the terminal 49 and the current flowing through the lower part of the movable contact 50, as shown by arrows in the figure. The direction of the rain is opposite to that of the rain, and electromagnetic repulsion is generated between the raindrops. The same applies when current flows from the movable contactor 50 to the terminal 49. Therefore, the electromagnetic iron piece 51
, 53 is reduced, and when a large current such as a short circuit current flows, electromagnetic repulsion causes contact 51 .
54 opens.

When an electromagnetic repulsion experiment was conducted using this conventional contact mechanism, electromagnetic repulsion occurred when a current of 1500 A was applied.

On the other hand, in the main contact mechanism of the embodiment, as shown in FIG. They are placed facing each other with their tips facing oppositely. Therefore, for example, when a current flows from the terminal 41 to the movable contact 37, the direction of the current flowing through the vertical piece on the tip side of the L-shaped portion 41a of the terminal 41 and the direction of the movable contact 37 are determined as shown by the arrows in the figure. The direction of the current flowing through the bottom becomes the same. Therefore, almost no electromagnetic repulsion is generated between the tip side edge piece of the L-shaped portion 41a and the lower part of the movable contactor 37. Therefore, there is less possibility that the contact 43 of the terminal 41 and the contact 38 of the movable contact 37 will open due to electromagnetic repulsion, resulting in excellent short circuit resistance. If the electromagnetic iron piece 44 is fixed to the bottom of the U-shaped part 41a as shown in FIG.
a covers about three quarters of the circumference of the electromagnetic iron piece 44, so the amount of magnetic flux passing through the electromagnetic iron piece 44 generated by the current flowing through the U-shaped portion 41a increases, and the electromagnetic iron piece 44
begins to strongly attract the electromagnetic iron piece 39. As a result, the possibility that the contacts 38 and 43 will separate from each other is further reduced, and the short circuit resistance is further improved.

When an electromagnetic repulsion experiment was conducted using a contact mechanism as shown in FIG. 11, no electromagnetic repulsion occurred even when a current of 2500 A was applied.

Further, in the embodiment, the oscillating body 25° movable contact 37 and the contact pressure spring 36 are combined as described above, and the oscillating body 25
is provided with a pressing portion 25a, so even if the contact of the movable contact 37 and the contact 43 of the terminal 41 of the main contact mechanism are welded together when turned on, both contacts will be automatically and reliably held at 37° when turned off. 43 can be opened. This is due to the following reasons.

Conventionally, as shown in FIG.
A movable contact 57 is used which is fixed at 5 and has a contact 56 at the other end, and the contact 56 of this movable contact 57 and the fixed contact 58
If the two contacts 56. and 56.
58 was made to open. However, in this case, the opening force is divided into two parts as shown by arrow M, making it difficult to open both contacts 56 and 58.

On the other hand, in this embodiment, if the contact 38 of the movable contact 37 and the contact 43 of the terminal 41 are welded during the ON state, when the OFF operation is performed, as shown in FIG.
As the rocking body 25 rotates and both supports 32.33 move away from the movable contact 37, the movable contact 37 moves away from both the supports 32.33.
Independent from 33. As a result, a force in the direction of arrow N is applied by the contact pressure spring 36 to rotate the movable contact 37 about both contact points 43 and 38.

In this case, the force of the contact pressure spring 36 acts to force the welded portion apart, so that the welding separation effect becomes very large. Then, as the rocking body rotates further as shown in FIG. 14, the pressing portion 25a hits the movable contact 37 and applies an impact force, so that an even higher welding and separating effect can be obtained.

Because of this, the welded contacts 37, 43 can be automatically and reliably opened.

In the embodiment, the manual operation section 26 is provided on the rocking body 25,
This manual operation part 26 is made to be visible outside through the notch 1a of the body 1. Therefore, the power supply circuit of the load can be opened and closed not only by a remote control switch but also manually, which is very convenient.

In the embodiment described above, the auxiliary contact mechanism consisting of the printed circuit board 13, contact plates 19a, 19b, contact spring parts 20, etc. is fixed to the support plate 12 to form a block, and this block is integrated with the electromagnet device 4. ing. Further, a contact pressure spring 36 and a movable contact 37 are arranged on the oscillating body 25 to form a block, and this block is formed by the oscillating body 25.
5 is integrated with the electromagnet device by being pivotally fixed to the electromagnet device. In this way, if the main mechanisms other than the electromagnet device are made into blocks and each block is integrated with the electromagnet device, it is easier to assemble the relay than if each part is assembled separately. At the same time, the electromagnetic device allows the positions of other major mechanisms to be determined accurately, resulting in stable relay characteristics. Furthermore, if the terminals 14 and 15 for connecting the operating circuit are also fixed to the support plate 12 as in the embodiment, there is no need to provide a separate terminal section, making assembly even easier. This also makes it possible to reduce the number of parts.

As in the above embodiment, the oscillator 25 is arranged between the electromagnet device 4 and the terminals 41 and 42 of the main contact mechanism, and the vertical axis of the oscillator 25 is sandwiched between the electromagnet device 4 and the movable contact 37. By doing so, the electromagnet device 4 and the main contact mechanism are insulated from each other, so that the mutual electromagnetic influence between them is reduced, and the performance of the relay is improved.

This relay is fully capable of handling high capacity loads such as HID (mercury halogen) lamps.
