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

Figure 1 is an exploded perspective view showing the appearance of the outlet structure according to the present invention, will be described with reference to this.

The outlet 100 according to the present invention includes a main body 170 installed in a wall, a front case 110 covering the main body 170, a support 130 installed in the main body 170, and the Rotating cylinder 120 is rotatably fixed to the support 130, and the operation circuit for controlling the opening and closing of the rotating cylinder (120).

The front case 110 has a pair of insertion holes 11 into which the energizing bar 11 of the plug 10 is inserted, and is fixedly disposed on the front surface of the main body 170.

The conduction bar 11 inserted through the insertion hole 11 can no longer be inserted while contacting the rotating cylinder 120. Of course, the rotary cylinder 120 is made of an insulating material, the electrical connection with the current collector 160 is cut off.

On the other hand, the rotating cylinder 120 is inserted into the rotating hole 131 formed in the support 130 while forming a cylindrical shape is rotatably fixed, a pair of fan-shaped inclined path 121 in the front of the rotating cylinder It is disposed to face each other with respect to the rotation center of the 120, a space is formed between the pair of ramps 121. In this case, through holes 123 into which the energizing bar 11 of the plug 10 is inserted are respectively formed in the spaces. Meanwhile, a rotating shaft 123 is formed at the center of the rotating cylinder 120, and the rotating shaft 123 is connected to and fixed to the fixed body 150 formed on the main body 170.

The rotary cylinder 120 is the inclined surface formed on the front surface of the rotary cylinder 120, the pressure of the energizing bar 11 for applying a force in the horizontal direction when the stopper 181 preventing the rotation of the rotary cylinder 120 is released While being applied to 121, a rotational force about the rotation shaft 123 occurs.

That is, the rotary cylinder 120 is rotated by the cam method between the energizing bar 11 and the inclined surface 121. The through-hole 124 and the conduction bar 11 are arranged in a straight line in the front surface of the rotating cylinder 120 rotated so that the conduction bar 11 passes through the user when the user continuously applies a force to the plug 10. 124 is inserted.

On the other hand, when the pressure of the energizing bar 11 is released from the rotary cylinder 120, the rotary cylinder 120 should be returned to its original position. To this end, the rotating shaft 123 is rotatably fixed with the fixing body 150 via the torsion spring 140, because the plug 10 is separated from the outlet 100, the rotating cylinder 120 When the pressure of the furnace is removed, the rotational force of the torsion spring 140 is applied to the rotation shaft 123 to return the rotation cylinder 120 to the original position.

On the other hand, the outer peripheral surface of the rear end of the rotary tube 120, that is, the portion inserted into the rotary hole 131 is provided with a rotary groove 125 cut in close contact with the rotary hole 131, the rotary groove ( 125 is provided with a pair of energizing pieces 126 electrically connected to the energizing bars 11 inserted into the through holes 124, respectively.

Corresponding to the energizing piece 126, the energizing iron 160 is disposed on the inner circumferential surface of the rotating hole 131 in contact with the rotary cylinder 120.

2 is a view sequentially showing the operation of the rotating cylinder according to the present invention, will be described with reference to this.

The conducting piece 126 and the conducting iron 160 are not electrically connected to each other, as shown in FIG. However, when the rotary cylinder 120 rotates under the pressure of the energizing bar 11, the energizing piece 126 also rotates along the rotary cylinder 120 to approach the energizing iron 160. As shown in FIG. 2 (b), the energizing piece 126 and the energizing iron 160 are completely in contact with each other to form an electrical connection.

That is, even if a metal material is introduced into the through hole 124 through the insertion hole 111, an electric shock accident by the metal material may not occur at all unless the rotating cylinder 120 is rotated.

On the other hand, the support 130 is preferably to be separated from the body 170 for the management of the outlet (100). Therefore, the support groove 133 is formed in the support 130 for accurate disassembly and assembly with the main body 170, and the locking jaw 171 engaged with the support groove 133 on the inner wall of the main body 170. ) Is formed.

As a result, even if the support 130 is removed from the main body 170, the support 130 can be disposed in the correct position by engaging the support groove 133 and the locking step 171, the outlet 100 There is an advantage of easy management.

On the other hand, the energizing rod 160 is connected to the wire (W) wired in the building, the energizing bar 11 via the insertion hole 111 and the rotary cylinder 120 and the guide tube 131 is engaged with each other. As such, the energizer 160 is connected to the wire (W) wired in the building.

On the other hand, the outlet 100 according to the present invention is further provided with a first conducting plate 127 in addition to the conducting piece 126 in the rotating groove 125, the corresponding rotation hole 131 of the support 130 The second conducting plate 132 is disposed.

In addition, the first conducting plate 127 and the second conducting plate 132 are connected by the wiring as shown in FIG. 5, and are involved in the operation of the electromagnet 184. That is, when the first conducting plate 127 and the second conducting plate 132 are electrically connected, the electromagnet 184 will operate according to the operation of the following switch, but the first conducting plate 127 and the first conducting plate 127 will be operated. If the two conducting plates 132 are electrically separated, the electromagnet 184 cannot operate regardless of the operation of the switch.

To this end, the first conducting plate 127 and the second conducting plate 132 are normally in contact with each other to be electrically connected, and when the rotary cylinder 120 is rotated by the insertion of the conducting bar (11) As the first conducting plate 127 and the second conducting plate 132 fall, the operation of the electromagnet 184 is forcibly stopped.

This may be unnecessary power consumption if the electromagnet is operating even at the moment when the plug 10 is plugged into the outlet 100, so that the hanger 181 is separated from the groove 122 and the rotating cylinder 120 rotates. The power of the electromagnet 184 pulling the hanger 181 is cut off so that the hanger 181 is no longer pulled out. In addition, when the rotating cylinder 120 is returned to its original position by the restoring force of the torsion spring 140, the catch 181 is supported by the elastic force of the carcass 182, and then inserted into the groove 122 when it appears. It is locked so that the rotating cylinder 120 does not rotate.

Description number 'W3' is a medium for electrically connecting the first conducting plate 127 and the second conducting plate 132 to the electromagnet 184.

3 is an exploded perspective view illustrating a front case of a safety type installation structure of an outlet according to the present invention, and FIG. 4 is a view sequentially illustrating an operation mode of an electricity bar insertion hole of the front case, which will be described with reference to the drawing.

The rotary cylinder 120 is always maintained in a fixed state by the hanger 181. However, when the energizing bar 11 is inserted through the insertion hole 111, the rotary barrel 120 should be able to insert the energizing bar 11 to the energizing iron 160 while rotating.

To this end, the outlet 100 according to the present invention includes a hanger 181 and an operation circuit for operating the hanger 181.

First, the switch which can open and close the said operation circuit is demonstrated.

The switch is located in the insertion port 111 and can be opened and closed depending on whether the conduction bar 11 is inserted. To this end, the switch is arranged such that a plurality of opening and closing plates 113 having a fan shape is circular, and partially closes the insertion hole 111. That is, when the opening and closing plate 113 gathers to form a circle, the opening groove 116 is formed to be formed at the center of the circle. The opening and closing plate 113 gathered in this circle is fixed to be movable in the fixing box (112). At this time, the outer edge of the opening and closing plate 113 is provided with a first current collector 114, and correspondingly the second current collector 115 is provided to be spaced apart from each other inside the fixing box 112.

That is, as shown in Figure 3 (a), the opening and closing plate 113 is fixed to be movable in the center of the fixing box 112, the fixing is a locking protrusion 113a protruding in front of the opening and closing plate 113. It is made through a tension belt 117 winding. That is, while the tension belt 117 surrounds the engaging protrusion 113a formed on each of the opening and closing plates 113, the tension belt 117 is normally as shown in FIG. 3 (a) by the elasticity of the tension belt 117. To be integrated in the center of the fixing box 112.

On the other hand, when the energizing bar 11 is inserted through the fitting groove 116, the insertion force exceeds the tension of the tension belt 117 to open and close the opening and closing plate 113, the energizing bar 11 When fully penetrates through, the first current collectors 114 positioned at the edge of the opening and closing plate 113 come into contact with the second current collectors 115 disposed on the inner wall of the fixing box 112.

In this case, a plurality of the second current collectors 115 are disposed apart from each other. Accordingly, the first pair of current collectors 115 independently disposed at the edges of the opening and closing plate 113 become the current transfer mediums of the second current collectors 115, so that the designated pair of second pairs connected to the wires W1 are provided. It is to allow the whole current to be energized. At this time, the wire W1 is a wire constituting the operation circuit.

Figure 5 is a circuit diagram showing the operating circuit of the locking bar for locking the rotating body of the safety installation structure of the outlet according to the present invention, will be described with reference to this.

Such a structure can expect the following effects. That is, the opening and closing plate 113 is integrated to form a plurality of circular, only one place of the moving by the force, the first whole body 114 of the moved opening and closing plate 113 is fixed in the 112 Even when the second current collector 115 is energized, normal current is not flown in the operating circuit according to the present invention since the full energization of the remaining portion is not performed.

However, the operation circuit is connected to the electromagnet 184 to manage whether or not the magnetic force of the electromagnet 184. That is, when the first current collector 114 and the second current collector 115 are in contact with each other and a normal current is supplied to the operation circuit, magnetic force is generated in the electromagnet 184 to pull the latch 181. . On the other hand, when the electromagnet 184 does not operate, the hanger 181 is supported by the ballistic body 182, so as to push the hanger 181 into the groove 122 of the rotating cylinder 120, The rotating cylinder 120 is caught by the hanger 181 to prevent rotation. At this time, the hanger 181 is fixed to be movable in a straight direction through the guide 183, the hollow is formed, one end is inserted into the groove 122, the other end is inserted into the guide 183, the electromagnet When the magnetic force of 184 does not occur, the rotating cylinder 120 is unable to rotate. Of course, when the electromagnet 184 is operated to generate a magnetic force, the hanger 181 is moved toward the electromagnet 184 through the guide 183, one end thereof is separated from the groove 122, and eventually, the The rotating cylinder 120 is not subjected to interference that prevents rotation.

To this end, when the first current collector 114 and the second current collector 115 are electrically connected in series, at least one of the first current collector 114 and the second current collector 115 is not in contact with each other. The actuating circuit causes the normal current to be disturbed. In addition, the electricity supplied to the operation circuit may be supplied by being connected in parallel to the wire (W).

On the other hand, the outlet 100 according to the present invention is a pair of the hanger 181 is also formed corresponding to the pair of the insertion port 111. That is, the hanger 181 disposed in one insertion hole 111 is operated by an operation circuit including an opening and closing plate 113 and a fixing box 112 disposed in the insertion hole 111, and is disposed in the other insertion hole remaining. Each hanger is operated independently by an operation circuit including an opening and closing plate and a fixing box disposed in the insertion hole.

As a result, when the general person puts a metal material into one of the insertion holes of the pair of openings, the operation circuit including the opening and closing plate 113 and the fixing box 112 disposed on the insertion hole 111 is energized, the hanger 181. Even if the operation, the hanger associated with the insertion hole of the other side does not operate, the rotating cylinder 120 can not be rotated and the metal material can no longer be inserted.

On the other hand, as described above, while the first conducting plate 127 and the second conducting plate 132 is further included in the operation circuit, whether the short circuit between the first current collector 114 and the second current collector 115. Regardless of this, the entire short circuit of the operating circuit is controlled.

5 (a) is a state before the plug 10 is plugged into the outlet 100, that is, a general state, Figure 5 (b) is a plug 10 is plugged into the outlet 100, the electromagnet 184 is operated This shows the state in which the hanger 181 is separated from the groove 122, and FIG. 5 (c) shows that the plug 10 is fully inserted to allow the first conducting plate 127 and the second conducting power. As the plate 132 is short-circuited, the electricity supplied to the electromagnet 184 is cut off and the operation is stopped.

Unexplained withdrawal number "112a" is a through-hole formed in the fixing box 112, so that the energizing bar 11 inserted through the insertion hole can be inserted through the fixing box 12 more inwards. It is a passage.

According to the present invention as described above, the outlet according to the present invention is to block the metal material is inserted into the rotary tube when the non-promised metal material such as pins, nails, etc. attempts to insert through the insertion hole in addition to the promised plug Since the insertion is blocked further, it is possible to prevent the occurrence of electric shock accidents caused by the metal material, and to prevent large accidents caused by various short circuits in advance.
