And a fixed iron core 21 for inducing the movement thereof are disposed up and down, and the movable iron core 15 is magnetized according to the presence or absence of power of the coil 19 to the fixed iron core 21 to which the power supply coil 19 is assigned. ) Can be pulled.

In addition, a return spring 16 and an insulating block 20 are disposed between the movable core 15 and the fixed core 21 to impart a restoring force to the movable core 15 and to insulate between the cores. Let's do it.

The upper case 12 and the movable block 14 are provided with a plurality of input side fixed terminals 10, an output side fixed terminal 11, and a movable terminal 13 that can be connected and shorted to each other.

In this case, the output side fixed terminal 11 is directly connected to the external output terminal 29. Accordingly, when the power cord of the electrical appliance is connected to the external output terminal 29, the input side fixed terminal 10 → the movable terminal 13 → the output side of the fixed terminal (11) can be supplied with power to the electrical appliance.

Here, in the accompanying drawings showing an embodiment of the present invention, only one external output terminal is shown, but when the number of fixed input / output side terminals is increased or one output side fixed terminal and multiple external output terminals are connected in one, It is also possible to use several electrical appliances at the same time.

The connection / short between the movable iron core 15 and the fixed iron core 21 which means an on / off state in the outlet of the present invention including such a basic component generates magnetic force by the power supplied to the coil 19.

In order to make contact between the movable block 14 and the one-way switch 22, an induction protrusion 27 is formed on the side of the movable block 14, and the induction protrusion 27 is guided by the one-way switch 22. If it is guided along the groove 23 and constrained to a predetermined position, the rising position or the lowering position of the entire movable block 14 can be determined.

That is, when the induction protrusion 27 of the movable block 14 is seated in the recess of the lower end of the induction groove 23 of the one-way switch 22, the movable block 14 is in the lowered position. Will be in position.

In addition, the present invention adopts a push button of a manual operation method or a method of applying a pulse wave using a remote control wired / wireless remote control means as a method of supplying power to the coil 19 side.

For example, when the pulse wave power is applied to the coil 19 side by the operator's remote control operation, it is separated immediately after the one-time contact action between the movable iron core 15 and the fixed iron core 21.

However, even when the movable iron core 15 and the fixed iron core 21 are separated in this way, the outlet can be maintained in an on state by the operation of the one-way switch 22.

In particular, the outlet of the present invention is characterized by providing a safety device that completely cuts off the power when overloaded.

To this end, there is provided a bimetallic safety device 29 extending downward so as to be disposed close to the bottom of the one-way switch 22 side while forming a contact with the output side fixed terminal 11, whereby the bimetallic safety device 29 in case of overload When the expansion and the lower end of the one-way switch 22 is folded in the surface direction, that is, the side direction of the case, the induction projection 27 on the side of the movable block 14 from the induction groove 23 of the one-way switch 22. As the restraint force is released while the movable block 14 and the movable iron core 15 including the movable terminal 13 are lifted up by the force of the return spring 16, the fixed input / output side terminal ( 10), (11) is disconnected and at the same time all the poles of the outlet is cut off the power of the outlet is completely cut off.

Accordingly, it is possible to fundamentally solve the risk of various safety accidents such as a short circuit or a short circuit through the outlet or a fire.

Therefore, the operation state of the outlet according to the present invention configured as described above is as follows.

Figure 3 is a schematic cross-sectional view showing a blocking state of the outlet according to the present invention.

As shown in FIG. 3, the movable block 14 and the movable iron core 15 are raised by the force of the return spring 16, and the movable block 14 at this time is the one-way switch 22. The rising position can be maintained without being restrained by.

That is, the connecting / shorting operation of the movable core 15 and the fixed core 21 is performed in a one-touch method (for example, a method in which the power is instantaneously supplied once according to the pulse signal and the movable core and the fixed core are attached and dropped once). It is made by the movement of the movable block 14 and the movable core 15 is generated only, the energized state of the outlet is substantially in the lowering position maintenance of the movable block 14 using the restraining action of the one-way switch 22 Can be maintained.

This operation principle does not require the continuous on state of the electromagnet means, that is, the movable iron core 15 and the fixed iron core 21 as before, it is possible to configure an efficient wiring combination in terms of power consumption.

In addition, in order to switch from the energized state of the outlet to the interrupted state, if the power by the pulse signal is applied once more by operating a remote controller or the like, the movable iron core 15 is stuck once to the fixed iron core 21 side and falls off and the movable block 14 By slightly pulling down and releasing, the movable block 14 including the movable iron core 15 is returned to the lifted position by the repeated one-way restraining and releasing action of the one-way switch 22, so that the movable block ( At the same time as the rise of 14, the outlet can be switched to the blocking state by separation between the movable terminal 13 and the input / output side fixed terminals 10, 11 on the case.

The operation of the outlet is a manual operation of pressing the upper protrusion of the movable block 14 without relying on the connection / short operation between the movable iron core 15 and the fixed iron core 21 for supplying power through the remote controller or the like. The operation state of the outlet can be made in the same manner as in the automatic operation even in the manual operation of the movable block 14.
