In addition, the fixing means 500 is composed of a solenoid 510 and a plunger 520. Here, the solenoid 510 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 field is almost zero outside of the cylinder. A magnetic field 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 other words, the outlet of the solenoid 510 is arranged in the receiving groove 110 so that the door 230 is horizontally disposed on the wall surface W, the protruding plunger 520 is a locking projection 222 It is located in the case 100 to be disposed above. Here, the plunger 520 is an iron core formed to protrude forward. Therefore, when the magnetic force is generated in the solenoid 510 is pulled and moved to the inside of the solenoid 510 to rotate the outlet 200, if the magnetic force is not generated, protrudes to the outside of the solenoid 510 to engage 222 is engaged to prevent rotation of the outlet portion 200.

In addition, the input means 600 is electrically connected to the solenoid 510 such that a push switch is applied to the contact by being pressed once and energized. Therefore, by operating the input means 600 is energized or disconnected in accordance with whether the contact is connected or not, the supply of power to the solenoid 510 is controlled by the user. On the other hand, the input means 600 according to the present invention, as well as the push switch through the operation of the tumbler switch and the like can be applied to a variety of switches of the attached and falling method.

As shown in FIG. 3, the light emitting means 700 includes a lamp 710, a battery 720, and a switch 730. Here, the lamp 710 is installed in the case 100, it is preferable if the installation is possible to confirm whether the lighting from the outside, the light emitting diode that emits light only a certain voltage or more as a low-voltage driving device as the lamp 710 It is possible to apply. The battery 720 is connected to the lamp 710 in series to supply power, and is a general-purpose battery that can be easily obtained on the market. Finally, the switch 730 is composed of first and second terminals 731 and 732 which control the power supply from the battery 720 to the lamp 710 through mutual opening and closing. In addition, the first and second terminals 731 and 732 are always open, and the first terminal 731 is exposed to the receiving groove 110, so that the plug connector 220 is disposed horizontally in the receiving groove 110. If the first terminal 731 is pressed, the first terminal 731 is closed with the second terminal 732 and energized so that the lamp 710 is turned on.

Hereinafter, referring to FIG. 2 and FIGS. 4 to 6, the operation of the outlet housing box for the internal housing of the multi-family house is as follows.

When the outlet box according to the present invention is not used, the outlet part 200 has the door part 230 disposed at the front to close the receiving groove 110, and the protrusion 222 at the plunger 520. While the rotation is prevented, the rotation is always forward and is installed in the receiving groove 110 so as to be pulled out, while the plug connecting portion 220 is disposed horizontally in the receiving groove 110, so that the plug connecting portion 220 is connected to the first terminal ( By pressing 731, the first terminal 731 is closed with the second terminal 732 to energize each other, and the lamp 710 is turned on (Fig. 2).

Since the outlet portion 200 is rotated by the elasticity of the torsion spring 400, the stopper 111 is engaged with the stopper 111, and rotation is prevented, so that the plug connection portion 220 is exposed to the front. By pressing the input means 600 again, the plunger 520 is exposed to the outside of the solenoid 510. At this time, since the plug connector 220 is vertically disposed in the accommodation groove 110, the first terminal 731 and the second terminal 732 are opened, and the lamp 710 is turned off (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 power to the electric appliance, while the lamp 710 is still off. (FIG. 5).

Finally, when the plug P is connected to the outlet box, the cord C of the electric appliance is placed in the cord passing groove 231, and then the input means 600 is pressed again to press the plunger 520 to the solenoid ( Inserted into the 510, the door part 230 is pushed and rotated to return the outlet part 200 to the receiving groove 110. In addition, since the current is not supplied to the solenoid 510 when the input means 600 is pressed again, the plunger 520 protrudes and is positioned above the locking protrusion 222, thereby preventing rotation of the outlet 200. do. On the other hand, since the plug connection part 220 is rearranged horizontally in the receiving groove 110, the plug connection part 220 presses the first terminal 731, so that the first terminal 731 is closed with the second terminal 732 so as to be mutually energized. The lamp 710 is turned on (Fig. 6).

Since the wire outlet box for the internal housing of the apartment house constructed as described above is formed such that the cord passing groove 231 is formed in the door part 230 so that the cord C passes through the cord passing groove 231, the plug P is connected. The outlet 200 can be rotated and seated in the receiving groove 110 even in the closed state. 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, since the wire outlet box for apartment house snow wire according to the present invention is rotated even when the plug (P) is connected to the outlet box, the plug (P) is completely concealed and external force applied directly to the plug (P) from the outside The effect that the plug P is protected from is expected.
