Additionally, a coupling portion coupled to the sensing case 651 may be formed at the lower portion of the sensing cover 653, and the coupling portion may be coupled to the sensing case 651 by forming a through portion on the side wall of the sensing case 651. Of course, the coupling portion and the penetrating portion may be excluded and coupled using other coupling means.

Meanwhile, the sensing case 651 is preferably inserted and fixed into the vibration unit mounting opening 615 formed in the housing unit 610. For this purpose, the lower surface of the sensing case 651 is preferably formed to have an area corresponding to the vibration unit mounting opening 615. In addition, the sensing case 651 is preferably formed with a side wall protruding upward along the edge of the lower surface.

Next, it is preferable that the sensing cover 653 made of an insulating material is provided on the upper part of the sensing case 651 and has a through hole 656 through which the connecting piece 648a and the connecting piece 649a penetrate and are exposed. .

In detail, the detection cover 653 may be formed with a through hole 656 through which the connection piece 648a and the connection piece 649a pass, and the through hole 656 allows the connection piece 648a to pass through. It is formed of a first through hole 656a penetrating and a second through hole 656b through which the connecting piece 649a penetrates. Of course, it is preferable that the first through hole 656a and the second through hole 656b are formed spaced apart from each other.

At this time, the connection piece 648a passes through the first through hole 656a and is exposed to the upper part of the detection cover 653 to be connected to the plug connection portion 632, and the connection piece 649a is connected to the detection cover 653. It is preferable that it passes through the second through hole 656b of 653 and is exposed to the upper part of the detection cover 653, thereby connecting to the modular blocking unit 680.

As shown in Figures 2 and 3, the connection piece 649a is connected to the first connector 660, and the first connector 660 is connected to an auxiliary connection line 662. Additionally, the auxiliary connection line 662 may be connected to the second connector 661 and connected to the modular blocking unit 680.

At this time, the first connector 660 and the second connector 661 are preferably made of a conductive material such as conductive metal such as brass, and the auxiliary connection line 662 is also made of a conductive material, but is formed on the outer surface. It is more preferable that a covering of the heat transfer element material is formed.

Meanwhile, the connection piece 649a may be coupled to the first connector 660 using screws and pieces, and one end of the auxiliary connection line 662 is coupled to the first connector 660 and the other end is connected to the first connector 660. It is connected to the second connector 661. And, the second connector 661 can be coupled to the blocking cover 683 included in the modular blocking part 680.

As shown in FIG. 8, the modular blocking unit 680 is connected to the blocking unit mounting opening 614 so that when vibration occurs, the partition-type vibration sensing unit 640 and the vibration conductive unit 647 are energized to apply current. It is provided to be coupled to, and preferably includes a blocking case 681, the blocking cover 683, a plunger 687, and a solenoid 689.

In detail, a storage space is formed inside the blocking case 681, and the plunger 687 is stored in the storage space. In addition, the storage space is provided with an elastic means 682 for elastically supporting the plunger 687 downward, and the elastic means 682 is preferably located at the lower end of the solenoid 689 and the plunger 687, which will be described later. It is preferable that it is interposed between the stopping ends 687a determined in the radially outward direction.

In addition, the elastic restoring force of the elastic means 682 may be formed with a force smaller than the magnetomotive force of the solenoid 689. Therefore, when vibration occurs, the plunger 687 can be easily attracted to the solenoid 689 by turning off the power of the outlet 700, which will be described later, and when the magnetomotive force is removed, the plunger 687 is moved to the elastic means 682. ) can be easily returned downward through the elastic resilience of ).

At this time, the blocking case 681 and the blocking cover 683, which will be described later, are preferably formed of an electrically insulating material such as synthetic resin, like the housing portion 610. In addition, the blocking unit mounting opening 614 is formed through a cross-sectional area of the modular blocking unit 680, and the blocking unit is mounted on at least one of the blocking case 681 and the blocking cover 683. A coupling protrusion 683c may protrude to be coupled to the edge of the opening 614 through a coupling means.

In addition, the plunger 687 extends in the vertical direction below the hollow portion 634 to be able to be raised and lowered in the storage space, and is elastically supported downward through the elastic means 682. In addition, the plunger 687 is preferably aligned concentrically with the hollow portion 634 through the central hole 689c of the solenoid 689 and the through hole 683d formed in the blocking cover 683.

In addition, the solenoid 689 is fixed to the upper end of the blocking case 681 and is provided to surround the upper outer periphery of the plunger 687. An anode end 689b and a cathode end 689a are spaced apart from each other and protrude above the solenoid 689. At this time, the positive end 689b is provided to contact the power terminal 630 disposed in the mounting space 612 to which the modular blocking part 680 is coupled, and the negative end 689a is connected to the blocking cover. It is preferable that it contacts the second connector 661 coupled to (683).

At this time, the blocking cover 683 covers the upper part of the solenoid 689, and blocks the second connector 661 connected to the partition-type vibration detection unit 640 to contact the negative terminal 689a. The second connector 661 is connected to the cover 683, and a ground opening 684 through which the cathode end 689a passes is formed. In addition, it is preferable that a protruding hole 685 through which the positive end 689b protrudes and contacts the power terminal 630 on one side is formed on the other side of the blocking cover 683, which is spaced apart from the ground opening 684. .

Referring to FIGS. 8A and 8B, when vibration occurs, the outlet 700 is connected to the power terminal 630 on one side, the solenoid 689, the partition-type vibration detection unit 640, the vibration energizing unit 647, and When the power terminal 630 on the other side is connected and energized, the modular blocking unit 680 is operated.

In detail, when power is applied to the solenoid 689, magnetomotive force is generated and the plunger 687 is drawn into the solenoid 689 and rapidly moves upward. Accordingly, the upper end of the plunger 687 is drawn upward into the hollow part 634 and the power plugs P1 and P2 in contact with the hollow part 634 are pushed upward with strong force. Through this, the power plugs (P1, P2) are separated from the hollow portion 634, so the current can be automatically blocked.

That is, through the operation of the modular blocking unit 680, the power plugs P1 and P2 are separated from the hollow part 634 and the electrical connection is released, thereby blocking the current. At this time, when the plunger 687 moves upward, the elastic means 682 is compressed.

Here, when the power plugs (P1, P2) are separated from the hollow portion 634 through the operation of the modular blocking portion 680, the body portion (PA) of the power plug is connected to the coupling fixing groove portion 553. It protrudes outward. Therefore, the user can visually check the body portion (PA) of the power plug protruding to the outside of the outlet 700, immediately determine that the current is blocked, and proceed with subsequent processing. Since the blocking state can be maintained, safety can be significantly improved.

In addition, when vibration due to an earthquake or impact occurs around the housing unit 610, the partition-type vibration detection unit 640 performs a hinge movement to selectively contact the vibration conductive unit 647. maintain. Accordingly, since the energized state of the solenoid 689 and the connection terminal 130 is maintained, the plunger 687 can be maintained in a state in which it is attracted by the magnetomotive force of the solenoid 689. Through this, even if the power plugs (P1, P2) are inserted into the hollow portion 634 due to the suction rise of the plunger 687, they can be removed again.

At this time, when the vibration caused by the earthquake and impact around the housing unit 610 disappears, the partition-type vibration sensing unit 640 returns to its original shape due to the elastic restoring force of the spring 646, and the vibration energizing unit 640 returns to its original shape. It remains apart from (647). Accordingly, current flow between the pair of power terminal units 630 connected through the first connector 660 and the second connector 661 is blocked. Accordingly, the magnetomotive force of the solenoid 689 is lost.

And, the plunger 687 is elastically supported downward through the elastic restoring force of the elastic means 682. Through this, when the power plugs (P1, P2) are reinserted into the hollow portion 634, the plug connection portion 632 and the power plugs (P1, P2) come into electrical contact again, causing current to flow.

Subsequently, the partition-type vibration detection unit 640 and the vibration current conduction unit 647 are mounted inside the detection case 651 and provided as one assembly, making assembly easy and driving reliability improved through accurate coupling between parts. Not only is this improved, but only the sensing case 651 can be separated and replaced or repaired and reassembled for use, thereby significantly improving maintainability.

In addition, when vibration due to an earthquake or impact occurs around the housing unit 610, the partition-type vibration detection unit 640 moves the hinge movement of the partition 642 by hitting the weight 641. It is preferable to understand it as a device that operates to separate the power plugs (P1, P2) from the hollow portion 634 to block the flow of current. In other words, not only does it have the function of blocking the current flow when an earthquake occurs, but it can also prevent secondary safety accidents by detecting shaking caused by external shocks and stably blocking the current flow.

At this time, it is preferable that a communication portion 616a accommodating the auxiliary connection line 662 connecting the first connector 660 and the second connector 661 is recessed in the partition wall 616. Accordingly, the auxiliary connection line 662 is prevented from interfering with the ground member 560, and thus operational reliability can be further improved.
