Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view of a buried receptacle for preventing accidents of a multi-family house according to the present invention, Figure 2 is a schematic view of a buried receptacle for preventing accidents of a multi-unit house according to the invention, Figure 3 is a driving means according to the present invention Is a schematic circuit diagram of.

The outlet according to the present invention, the case 100, the outlet 200, the outlet terminal 300, the drive means 400 and the earth leakage breaker 500.

Here, the case 100 according to the present invention is provided with a receiving groove 110 opened forward, and is embedded so that the storage groove 110 is exposed on the wall (W). In addition, the lower end of the receiving groove 110, when the outlet portion 200 is seated in the receiving groove 110 is formed a wire storage groove 111 for receiving the wire (L).

The outlet 200 has a plug connection portion 220 to which the plug P is connected and a door portion 230 formed to be connected to the plug connection portion 220 at right angles to form a 'B' shape as a whole. It is rotatably fixed to the inlet of the receiving groove 110 via the rotation shaft (210). Here, the plug connecting portion 220, the front end is rotatably fixed to the inlet of the receiving groove 110 via the rotation shaft 210. In addition, the terminal insertion hole 221 into which the plug terminal P1 is inserted is formed at an upper surface thereof, and a wire storage groove 223 in which the wire L is accommodated is formed.

Therefore, when the plug P is connected to the outlet, only the cord C can be exposed to the outside through the cord passing groove 231. In addition, the cord passing groove 231 according to the present embodiment is vertically upwardly formed in a part of the door part 230, but may be horizontally formed laterally, and variously modified without departing from the scope of the claims. It is possible.

 The outlet terminal 300 is disposed below the terminal insertion hole 221 so as to be energized when the plug terminal P1 is inserted into the terminal insertion hole 221 and is installed in the outlet 200. In general, the outlet terminal 300 is formed of a conductor of a flexible material and is fixed while tightening the plug terminal P1 when the plug terminal P1 is inserted.

The driving means 400 includes a motor 410, a first circuit portion 420, a second circuit portion 430, a lever 440, and a plunger 450 (FIG. 3).

Here, the motor 410 is rotated by changing the rotation direction of the output shaft 411 as the polarity of the DC motor changes. In addition, while the output shaft 411 is rotated, the rotation shaft 210 is also installed in the case 100 to rotate in the same direction.

The first circuit unit 420 includes a first power source 421, a first switch 422, and a solenoid 423, and is connected in series to the motor 410 to rotate the motor 410 in one direction. Here, the first power source 421 is a DC power supply source, it is possible to apply a general-purpose battery that can be easily obtained on the market. In addition, the first switch 422 is connected to the first power source 421 in a always open state and selectively energized. In addition, the solenoid 423 is generally used to operate various mechanisms such as a switch or a relay. When the current is flowed by winding the wire in a spirally and uniformly cylindrical shape, the magnetic force is almost zero outside the cylinder. A magnetic force having a relatively uniform size is formed therein, and is located at the rear of the plug connector 220 horizontally disposed in the accommodation groove 110.

In addition, the second circuit unit 430 includes a second power source 431 and a second switch 432. Here, the second power source 431 is the same DC power supply source as the first power source 421, the rotational direction of the output shaft 411 of the motor 410 is changed to be connected to rotate the rotating shaft 210 in the reverse direction. That is, the second power source 431 is reversed from the first power source 421 and is connected to the motor 410 by changing the pole. In addition, the second switch 432 is connected to the second power source 431 and the motor 410 in an open state at all times and selectively energized.

When the lever 440 is exposed to the case 100 and moved upward and downward, the first switch 422 or the second switch 432 is closed to close the first circuit part 420 or the second circuit part. A conductor is provided to selectively control the energization of 430. Here, the lever 440 is normally disposed in a neutral state, and of course, the first circuit unit 420 and the second circuit unit 430 are arranged in a disconnected state. In addition, when the lever 440 is moved upward, the first switch 422 is energized so that the motor 410 is rotated in one direction, and the rotation shaft 210 is also rotated in one direction so that the plug connector 220 is exposed to the outside. do. On the other hand, when the lever 440 is moved downward, the motor 410 is rotated in the reverse direction so that the second switch 432 is energized so that the exposed plug connector 220 is seated in the receiving groove 110.

The plunger 450 is an iron core formed to protrude always toward the front, and is fixed to the solenoid 423 through a spring (not shown). Therefore, when the plunger 450 does not generate magnetic force on the solenoid 423, the plunger 450 is engaged with the locking protrusion 222 by the spring force of the spring so that the outlet 200 cannot be rotated forward. On the other hand, the solenoid 423, when the magnetic force is generated in the solenoid 423 by generating a magnetic force greater than the elastic force of the spring, the plunger 450 is moved inside the solenoid 423, that is, rear. Therefore, the plunger 450 engaged with the catching protrusion 222 is moved backward by the spring force of the spring so that the rotation of the outlet 200 is prevented, so that the outlet 200 can be rotated forward. On the other hand, the plunger 450, the end surface 451 is formed to be inclined. Therefore, when the outlet 200 is to be rotated and seated in the accommodation groove 110, the end face 451 is pushed by the pressure of the locking protrusion 222 while the plunger 450 is rearward, that is, inside the solenoid 423. The outlet 200 is seated in the receiving groove 110.

And, the earth leakage breaker 500, A well-known technique consisting of a current transformer (not shown) and an electromagnet type driver (not shown) will be omitted. The earth leakage breaker 500 according to the present invention is installed in the case 100 to be electrically connected to the outlet terminal 300. Briefly, the current transformer is to induce a current flowing in the wire (L) through a coil (not shown) wound on the wire (L). In addition, the driver is an electromagnet type that is electrically connected to the current transformer and trips when a predetermined current or more. Here, the current transformer, commonly referred to as CT (Current Transfomer), is installed in the wire (L), detects the magnetic flux generated in the wire (L) to cause an inductive current in the coil wound in a predetermined number of times. Therefore, normally the amount of current flowing through the wire L in the coil is equal to each other and the magnetic flux cancels each other so that no induction current flows in the coil, and an electric leakage causes an inductive current in the wire L.

Hereinafter, the operation of the buried receptacle for preventing safety accidents of a multi-family house according to the present invention will be described with reference to FIGS. 2 and 4 to 6 as follows.

When the outlet according to the present invention is not used, the outlet portion 200 has a door portion 230 disposed in front to close the receiving groove 110, the plunger 520 is fixed to the spring elastically The locking protrusion 222 is installed in the receiving groove 110 in a state where rotation is stopped. In addition, the lever 440 is disposed in a neutral state so that the driving means 400 is not operated (FIG. 2).

In order to use the outlet according to the present invention, when the lever 440 is moved upward, the first circuit unit 420 is energized. Therefore, the solenoid 423, the magnetic force is generated to pull the plunger 450 to the rear. At the same time, the motor 410 is rotated in one direction. Accordingly, the outlet part 200 having the rotation shaft 210 fixed to the output shaft 411 of the motor 410 rotates forward to be exposed to the plug connection part 220 in association with the output shaft 411. Then, when the lever 440 is manipulated to be neutral again, the plunger 450 protrudes forward and the operation of the driving means 400 is stopped (FIG. 4).

When the plug connection part 220 is exposed to the front, the plug terminal P1 is inserted in accordance with the terminal insertion hole 221. When the plug terminal P1 is inserted into the terminal insertion hole 221, the plug terminal P1 and the outlet terminal 300 are connected to supply electric power to the electric device (FIG. 5).

Finally, when the plug P is connected to the outlet, the cord C of the electric appliance is placed in the cord passing groove 231, and then the lever 440 is moved downward, whereby the second circuit unit 430 is disposed. Is energized, and the motor 410 is rotated in the reverse direction. Therefore, the outlet part 200 is also rotated in the reverse direction in conjunction with this, when the locking projection 222 abuts the plunger 450, the locking projection 222 pushes the plunger 450 to the rear and the receiving groove 110 It is seated on). When the outlet part 200 is seated in the receiving groove 110, the plunger 450 protrudes forward again due to the spring force of the spring (FIG. 6).

In addition, when a short circuit occurs in the outlet according to the present invention, the ground fault circuit breaker 500 is operated to cut off the power supply to the electric appliance.

The buried receptacle for preventing safety accidents of the multi-unit housing configured as described above is provided with a cord passing groove 231 formed in the door part 230 so that the cord C passes through the cord passing groove 231, and thus, a plug P. Even when the state is connected to the outlet 200 by rotating it can be seated in the receiving groove (110). Therefore, it becomes possible to conceal the plug connection portion 220 and the plug P connected to the plug connection portion 220, thereby further preventing the infiltration of foreign matter into the terminal insertion opening (221).

In addition, the buried type outlet for safety accident prevention of a multi-unit house according to the present invention is rotated even when the plug P is connected to the outlet, so that the plug P is completely concealed and applied directly to the plug P from the outside. The effect that the plug P is protected from an external force is anticipated.

In addition, the buried receptacle for preventing safety accidents of the apartment house according to the present invention, the wire receiving grooves 111 and 223 are further formed in the receiving groove 110 and the plug connecting portion 220, the outlet portion 200 is the receiving groove 110 ), The wire L is seated in the wire storage grooves 111 and 223, so that the wire L does not affect the rotation of the outlet 200, so that the wire is smoothly rotated.

In addition, the buried type outlet for safety accident prevention of a multi-family house according to the present invention, the earth leakage breaker 500 is reinforced, the power supply is cut off when a short circuit occurs. Therefore, the electric current flows to a part of the body to prevent a large fire caused by an electric shock accident or heat supplied to the flammables, as well as only the outlet is blocked, there is an effect that the electrical equipment connected to the other outlet is normally operated.
