In addition, the elastic restoring force of the elastic means 83 may be formed with a force smaller than the magnetomotive force of the solenoid 89. Therefore, when vibration occurs, the plunger 81 can be easily attracted to the solenoid 89 by turning off the power of the outlet 100, which will be described later, and when the magnetic force is removed, the plunger 81 is moved to the elastic means 83. ) can be easily returned downward through the elastic resilience of ).

At this time, the blocking case 70 and the blocking cover 75, which will be described later, are preferably formed of an electrically insulating material such as synthetic resin, like the housing portion 10.

An anode end (89a) and a cathode end (89b) are spaced apart from each other and protrude above the solenoid (89). At this time, the positive end (89a) is provided to contact the power terminal portion (30) disposed in the mounting space (12) where the solenoid device (80) is coupled, and the negative end (89b) is provided to contact the blocking cover (75). ) is preferably in contact with the second connector 86 coupled to.

At this time, the blocking cover 75 covers the upper part of the solenoid 89, and blocks the second connector 86 connected to the pendulum-type vibration detection unit 40 to contact the negative terminal 89b. The second connector 86 is connected to the cover 75, and a ground opening 76 through which the negative electrode end 89b passes is formed. In addition, it is preferable that a protruding hole 77 through which the anode end 89a protrudes and contacts the power terminal 30 on one side is formed on the other side of the blocking cover 75, which is spaced apart from the ground opening 76. .

Below, the structure of the solenoid device 80 according to an embodiment of the present invention will be described.

In other words, the solenoid device 80 is fixed by inserting the blocking case 70 into the solenoid mounting opening 14, and includes the plunger 81 at the lower side of the storage space of the blocking case 70, and The elastic means 83 is included in the stopping end 81a, so that the plunger 81 can be elastically supported downward.

In addition, the solenoid 89 is provided on the upper side of the elastic means 83, and the blocking cover 75 is provided with the through hole 78 communicating with the central hole 89c of the solenoid 89. It is preferably provided on the upper part of the blocking case 70.

At this time, the blocking cover 75 penetrates the negative end (89b) and the positive end (89a) of the solenoid 89 while being spaced apart from each other, and the positive end (89a) is connected to the power terminal portion 30 on one side. It is in contact with the lower side of the hollow portion 34, and when vibration occurs, the negative electrode end (89b) is connected to the pendulum energizing portion 45 and is in contact with the lower side of the hollow portion 34 of the power terminal portion 30 on the other side to conduct electricity. You can.

Through this, the solenoid 89 can be energized by the pendulum-type vibration detection unit 40 and the pendulum energizing unit 45, thereby allowing current to be applied, and the solenoid 89 to which the current is applied is connected to the power plug. The plunger 81, which is provided to separate from the hollow portion on the other side, can be operated by pressing upward.

That is, when vibration occurs, the outlet 100 includes the power terminal 30, the solenoid 89, the pendulum-type vibration detection unit 40, the pendulum energizing unit 45, and the power terminal unit 30 on the other side. ) is connected and energized, the solenoid device 80 operates.

In detail, when power is applied to the solenoid 89, magnetomotive force is generated and the plunger 81 is drawn into the solenoid 89 and rapidly moves upward. Accordingly, the upper end of the plunger 81 is drawn upward into the hollow part 34 and the power plugs P1 and P2 in contact with the hollow part 34 are pushed upward with strong force. Through this, the power plugs (P1, P2) are separated from the hollow portion 34, so the current can be automatically blocked.

Referring to FIGS. 8A and 8B, in the present invention, when vibration occurs due to an earthquake or shock, current is applied to the solenoid device 80 through the operation of the pendulum-type vibration detection unit 40, so that the solenoid device 80 Through the operation of ), the power plugs (P1, P2) are separated from the hollow part 34, the electrical connection is released, and the current is blocked. At this time, when the plunger 81 moves upward, the elastic means 83 is compressed.

Here, when the power plugs (P1, P2) are separated from the hollow portion 34 through the operation of the solenoid device 80, the body portion PA of the power plug moves to the outside of the coupling fixing groove 93. It protrudes. Therefore, the user can visually check the body portion (PA) of the power plug protruding to the outside of the outlet 100, immediately determine that the current is blocked, and then proceed with subsequent processing. Since the blocking state can be maintained, safety can be significantly improved.

In addition, after the plunger 81 is moved upward through the operation of the solenoid device 80 and the power plugs (P1, P2) are separated, the user can determine whether the vibration caused by the earthquake or impact has disappeared. Through this, the power plugs (P1, P2) can be reconnected to the outlet 100.

Generally, earthquakes occur as foreshocks, mainshocks, and aftershocks. That is, after the outlet 100 is activated and reconnected due to the forward movement, it is preferable that the outlet 100 is re-operated when the main shock and aftershock occur.

To this end, the operation of the solenoid device 80 blocks the current flow between the pair of power terminal units 30, and at the same time, the magnetomotive force of the solenoid 89 is lost, and the plunger moves through the elastic force of the elastic means 83. (81) can be elastically supported again on the lower side of the blocking case (70).

In addition, when additional vibration such as main shock and aftershock occurs, the outlet 100 is energized with the solenoid device 80 through the operation of the pendulum-type vibration detection unit 40 described above, and the solenoid device 80 The plunger 81 of can be reactivated.

Therefore, the outlet 100 according to an embodiment of the present invention not only enables the operation of cutting off current due to vibration and shock through the pendulum-type vibration detection unit 40, but also blocks the power plugs (P1, P2) after cutting the current. ) can be reconnected, and can provide semi-permanent shock stability rather than a one-time use in which the current blocking function is re-performed when additional earthquakes or vibrations occur.

In addition, the pendulum-type vibration detection unit 40 detects shaking of a preset magnitude or greater in the surrounding environment and moves the pendulum, thereby providing an operation that automatically blocks the flow of current when shaking occurs due to an earthquake or external shock.

In addition, the pendulum-type vibration detection unit 40 is a device that operates to separate the power plugs (P1, P2) from the hollow part 34 not only through vibration caused by an earthquake, but also through external shock, thereby blocking the flow of current. Understanding is desirable.

In other words, it can prevent secondary safety accidents by not only blocking the flow of current when an earthquake occurs, but also detecting shaking caused by external shocks and stably blocking the flow of current.

In addition, each component of the vibration-sensing pendulum-type plug safety separation outlet 100 described above can be assembled and separated from each other. In particular, the pendulum-type vibration detection unit 40 and the pendulum current conduction unit 45 are mounted inside the sensing case and are provided as one assembly, so the mold of the housing unit is simplified, the defect rate is reduced, assembly is easy, and Not only can driving reliability be improved through accurate coupling, but only the pendulum-type vibration sensing unit 40 and the pendulum energizing unit 45 can be separated and replaced or repaired and then reassembled, thereby significantly improving maintainability.
