DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to facilitate a person skilled in the art to easily carry out the present invention.

The recessed socket is for connecting the plug of the electrical appliance to the external wall of the building through a metal material embedding box (not shown). In this case, two stranded power lines and a grounding line are connected to the inside of the embedding box , And the upper side and the lower side may be fixedly arranged so as to cover the front side of the embedding box through screws.

The metal-material embedding box is embedded in a wall of a building, and is formed of a box-shaped enclosure having a front portion opened, and two power lines and a ground line are drawn from the outside.

In the present invention, a built-in receptacle into which two plugs can be plugged is taken as an example.

1 and 2, the recessed type socket outlet according to the embodiment of the present invention includes a receptacle 100, and a tightly coupled socket 100 that is tightly coupled to the outer surface of the receptacle 100 rearward, And a waterproof portion 500 are included.

3 and 4, the receptacle 100 includes a receptacle cover 110, a receptacle body 130, a box cover 180, and a box body 190.

The socket main body 130 is plate-shaped, and a plug inserting port 131 in which a plug is inserted and seated is recessed from the front side to the rear side.

A pair of first pinholes 133 are formed in the bottom of the plug insertion port 131 so as to be inserted into the plug insertion port 131. When the plug is inserted into the plug insertion port 131, Respectively.

The outlet cover 110 is formed in a plate shape and has an opening 111 through the front and rear at a position corresponding to the plug inserting opening 131.

As shown in FIG. 5, the box body 190 is a box-shaped box having an open front. The box body 190 has a pin insertion portion 350 made of a metal in which a plug terminal is inserted, A spring pin 250 is provided.

A ground wire inlet 200 which can be connected to the ground spring pin 250 by inserting a ground wire to the rear surface of the box body 190 and a ground wire inlet 200 which can be connected to the pair of pin inserting parts 350 A power line inlet 300 is provided.

The box cover 180 is coupled to the front of the box body 190 so as to cover the open portion of the box body 190 as a plate.

A second pinhole 181 is formed in the box cover 180 at a position corresponding to the first pinhole 133 so that a terminal of the plug is inserted into the pin insertion portion 350.

A ground terminal 150 is connected to the front surface of the box cover 180 so as to be in contact with the plug and grounded so that the ground terminal 150 is in close contact with the ground .

The grounding case 150 is bent so as to have an elastic restoring force at both ends thereof and is extended to the socket main body 130 and the center portion is disposed to abut across the front surface of the box cover 180 in an oblique manner.

The ground band 170 is manufactured by press-working a metal plate, and a wall fixing hole 175 for fixing the ground band 170 to the embedding box or the like through the fastening means is formed through the upper and lower ends.

1 and 2, the close waterproof portion 500 is made of an elastic material such as silicone, rubber, or urethane so that the close waterproof portion 500 is tightly adhered to the outer surface of the socket body 130 and the box body 190, .

The close waterproofing part 500 may be formed in a shape corresponding to the outer shape of the socket body 130 and the box body 190 after the socket body 130 and the box body 190 are fastened. As shown in Fig.

The through-water shield 500 is formed with a through-hole 510 at a position corresponding to the ground wire inlet 200 and the power wire inlet 300.

The through-membrane part 510 is relatively small in thickness in the tightly sealed waterproof part 500, and can penetrate with less force than other parts.

The inner surface of the close waterproof portion 500 is formed in an embossed shape (not shown).

At this time, a rubber-based coding layer (not shown) may be formed on the outer surfaces of the socket main body 130 and the box main body 190.

First, the receptacle cover 110 is assembled to the front surface of the receptacle body 130 in an interference fit manner.

The box body 190 having the box cover 180, the grounding case 150 and the grounding band 170 assembled is assembled to the rear surface of the socket main body 130.

6, the close waterproof portion 500 is tightly coupled to the outer surface of the socket main body 130 and the box body 190 so as to be wrapped.

The embossed portion formed on the close waterproof portion 500 and the coating layer formed on the socket main body 130 and the box main body 190 are brought into close contact with each other so that the close waterproof portion 500 is in contact with the socket body 130, (Not shown).

7, the ground line and the power line are coupled to the ground line inlet 200 and the power line inlet 300, respectively.

The grounding line and the power line are connected to the grounding line inlet 200 and the power line inlet 510 through the grounding line inlet 200 and the power line inlet 300, 300 respectively.

The airtightness can be maintained even if the penetrating membrane portion 510 is penetrated by the ground wire and the power supply line because the contact portion is closely contacted with the ground wire and the power wire due to the elastic force of the close waterproof portion 500.

As described above, since the close waterproof portion 500 made of elastic material is installed inside the wall in a state of tightly fitting to the rear of the receptacle 100, moisture and moisture inside the wall can be discharged through the gap between the assembled parts It is possible to prevent the short circuit between the wires and the short circuit.

Since the pin insertion portion 350 is firmly fixed to the box body 190 by the box cover 180, when the plug terminal is inserted into or disconnected from the socket, the pin insertion portion 350, So that the pin insertion portion 350 is prevented from being detached from the box body 190.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be readily apparent that various substitutions, modifications, and alterations can be made herein.
