1 is a plan view of an outlet safety device 100 in which the inclined portion 122 is formed in the opening / closing part 120 according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the auxiliary wing 130 is formed in FIG. 1. 3 is a perspective view of FIG. 1, and FIG. 4 is a perspective view from the bottom of FIG. 1.

Outlet safety device 100 according to an embodiment of the present invention, as shown in the drawing, may include a main plate 110 and the opening and closing portion 120. The opening / closing part 120 may serve to open and close the through hole 520 of the outlet into which the connection terminal 420 of the plug is inserted or evacuated. Accordingly, the opening / closing part 120 may be disposed at a position corresponding to a position where the through hole 520 of the outlet is formed, and aligned with or separated from the through hole. In general, two through-holes 520 of the outlet are formed so that the connection terminals 420 of the two plugs can enter and exit, so the opening and closing portion 120 can also be formed in two correspondingly, but the outlets and plugs of each country In accordance with the specifications of the number of opening and closing portion 120 may be different. Hereinafter, for convenience of description, a description will be given based on a case where two opening / closing portions 120 are formed as illustrated in the drawings.

When the plug is connected to the outlet, the opening / closing part 120 is detached from the through hole 520 of the outlet and the through hole 520 of the outlet is opened, so that the plug connection terminal 420 is inserted into the outlet and contacts the power outlet. When the plug is disconnected from the outlet, the opening / closing part 120 is aligned with the through hole 520 of the outlet so that the outlet through hole 520 is closed, so that foreign matter such as dust is through the hole 520 of the outlet. Through it can be prevented from entering the inside of the outlet. Therefore, as the connection terminal 420 of the plug is inserted or evacuated into the through-hole 520 of the outlet, the opening / closing part 120 may be configured to open and close the through-hole 520 of the outlet by operating along a certain copper wire.

The opening and closing portion 120 is connected to the plug's connection terminal 420 so that the connection terminal 420 of the plug can be released from a position aligned with the through-hole 520 of the outlet when the connection terminal 420 of the plug is inserted into the through-hole 520 of the outlet. An inclined portion 122 in which an inclined surface is formed with respect to the rotational direction of the main plate 110 may be formed on the inlet side (where the inclined surface formed with respect to the rotational direction of the main plate is aligned in the through hole of the outlet). In the state, it will be apparent that the connecting terminal of the plug is an inclined surface formed in a direction to push the opening / closing portion 120 when inserted into the through hole of the outlet). The principle of opening and closing the through-hole 520 of the outlet as the connection terminal 420 of the plug is inserted or withdrawn into the through-hole 520 of the outlet will be described again below.

The main plate 110 is formed integrally with the opening / closing portion 120 between the opening / closing portions 120 so that the opening / closing portion 120 may be aligned or separated from the through-hole 520 according to the rotation of the main plate 110. Therefore, the main plate 110 is centered around the rotation center portion 112 provided in the central portion so that the opening / closing portion 120 rotates along a certain copper line and opens / closes the through hole 520 according to the rotation of the main plate 110. It can be configured to rotate.

The rotating elastic member is coupled to the rotating elastic member coupling portion 140 provided in the opening / closing portion 120 to apply elastic force to the main plate 110 in the rotational direction so that the opening / closing portion 120 is aligned with the through hole 520 of the outlet. It can be configured to maintain the state.

Here, it is not essential that the rotating elastic member coupling portion 140 is formed in the opening / closing portion 120, and the rotating elastic member coupling portion 140 may be formed on the main plate 110 depending on the situation. The rotational elastic member coupling portion 140 is irrespective of its formation position, and provides elastic force to the main plate 110 or the opening / closing portion 120 in a state where it is combined with the rotational elastic member 150 so that the rotational elastic member 150 does not deviate. It is preferably formed to be applied.

On the other hand, the outlet stabilizer of the present invention may further include an auxiliary wing 130 extending in the radial direction from the rotation center (112). 2, the auxiliary wing 130 is extended in a direction orthogonal to the direction extending between the opening and closing portion 120 may serve to open the ground terminal (not shown) of the outlet. In addition, the auxiliary wing may be configured to limit the rotation of the main plate 110 by extending longer than the opening and closing part 120 so that its end is caught or supported by the structure.

The bottom surface of the main plate 110 may be formed to protrude the rotation center portion 112 from other parts (in this case, the bottom surface is an opposite surface of the formed part of the opening / closing part 120, which means the side shown in FIG. 4) . That is, the bottom surface of the rotation center portion 112 protrudes more than the bottom surface of the other parts of the main plate 110, so that the main plate 110 can be supported from the bottom surface on which the main plate 110 is installed. At this time, the other part of the bottom surface of the main plate 110 will be spaced apart from the bottom surface by contacting the bottom surface of the rotation center part 112 except for the other part of the bottom surface of the main plate 110.

Or, even if the bottom surface of the rotation center portion 112 of the main plate 110 does not protrude, the bottom surface is configured to support the bottom surface of the rotation center portion 112 of the main plate 110, the main plate 110 ), Both ends may be separated from the bottom surface.

In this way, when both ends are spaced apart from the bottom surface of the main plate 110, the main plate 110 can be easily rotated based on the rotation center 112. In addition, when the opening / closing portion 120 is pressed through only one through-hole 520 among the through-holes 520 of the outlet, the side of the opening / closing portion 120 that is pressed is inclined downward and the side of the opening / closing portion 120 which is not pressurized This is tilted upward so that the main plate 110 can be prevented from rotating. That is, since the center of rotation 112 is in contact with the floor on the bottom surface of the main plate 110, and both sides are spaced from the floor, the main plate 110 that maintains the horizontal level is tilted when only one of the opening and closing portions 120 is pressed. By doing so, it is possible to prevent the rotation of the main plate 110. Therefore, the rotation center part 112 supporting the main plate 110 from the bottom surface prevents the connection terminal 420 or the chopstick of the plug from entering the inside of the outlet by entering only one side of the through hole 520 of the outlet. It becomes possible.

As shown in the figure, the outlet safety device 200 according to an embodiment of the present invention may be further provided with a housing 280 forming an exterior. The housing 280 may be integrally formed, but may be divided into first and second housings 281 and 282 for ease of fabrication and assembly. The housing 280 may modularize the outlet safety device 200 so that each component may be mounted in an outlet in an assembled state.

In the housing 280, the terminal hole 284 should be configured to allow the connection terminal 420 of the plug to penetrate from one side to the other side.

Inside the housing 280 is formed integrally with the opening and closing part 220 and the opening and closing part 220 disposed at a position corresponding to the position where the terminal hole 284 is formed so as to open and close the terminal hole 284 and the rotation center part 212 ) May be provided with a safety blade equipped with a main plate 210 that rotates based on.

As shown in the figure, the rotating elastic member 250, one side is coupled to the rotating elastic member coupling portion 240, the other side is supported by the structure formed inside the housing 280, the rotation direction to the main plate 210 It can be configured to apply an elastic force to.

In addition, according to an embodiment of the present invention, as shown in FIG. 6, a support elastic member 260 that is coupled to the rotation center 212 to apply elastic force to the bottom surface of the main plate 210 may be further provided. . When the support elastic member 260 is provided, when the connection terminal 420 of the plug presses the opening / closing part 220, the safety blade moves in a pressing direction by a predetermined distance, and when the pressing of the opening / closing part 220 is released The safety wing can be returned to its original position.

7 is a view showing a state before the connection terminal 420 of the plug is inserted into the through hole (if the housing is provided, including the terminal hole), Figure 8 is the connection terminal 420 of the plug is inserted into the through hole 9 is a plan view showing a state in which the opening / closing part 120 is aligned with a through hole (terminal hole), and FIG. 10 shows the main plate 110 rotating as the connection terminal of the plug enters in FIG. 9 It is a plan view showing the state.

7 to 10, as the connection terminal 420 of the plug is inserted into the through-hole 520 of the outlet or evacuated from the through-hole 520 of the outlet, the opening / closing part 120 is through-hole 520 of the outlet ) To know the principle of opening and closing.

7 and 9, the rotating elastic member 150 exerts an elastic force on the main plate 110, but the rotating elastic member 150 applies the elastic force in the opposite direction to the main plate 110 or the opening / closing part ( 120) The support is supported by the structure to limit the rotation of the main plate 110. Therefore, when the connection terminal 420 of the plug is not inserted into the through hole 520 of the outlet, the opening / closing part 120 may be aligned at a position corresponding to the through hole 520 of the outlet.

As illustrated in FIG. 8, when the connection terminal 420 of the plug is inserted into the through hole 520 of the outlet along the entry direction I, the end of the connection terminal 420 of the plug is opened and closed 120 Since the opening / closing part 120 is pushed out while acting relative to the opening / closing part 120 along the inclined surface of the opening / closing part 120, the opening / closing part 120 is deviated from a position aligned with the through-hole 520 of the outlet, and the connection terminal 420 of the plug is an outlet It can be inserted inside.

Then, as shown in Figure 10, the opening and closing portion 120 is pushed by the entry of the connection terminal 420 of the plug, the main plate 110 may rotate around the rotation center portion (112).

At this time, if a plurality of inclined portions 122 are provided, it will be apparent that all inclined surfaces of the inclined portions 122 should be formed in the same direction with respect to the rotational direction of the main plate 110.

11 is a view showing a state in which the non-slip portion 123 is formed on the inclined portion 122 as the opening and closing portion 120 according to an embodiment of the present invention, FIG. 12 is a perspective view of FIG. 11, and FIG. 13 is FIG. 11 It is a view showing a state viewed from the side of the opening and closing, and FIG. 14 is a view showing a state in which the shape of the non-slip portion is deformed in FIG. 13.

As shown in the drawing, according to another embodiment of the present invention, the opening / closing portion 120 has an inclined portion in which an inclined surface is formed with respect to the rotational direction of the main plate 110 on the side where the connecting terminal 420 of the plug enters ( 122) is provided, the non-slip portion 123 may be formed on the inclined surface of the inclined portion 122.

The opening / closing unit 120 is configured to open and close the through-hole 520 of the outlet as the plug is connected to and disconnected from the outlet, thereby preventing the introduction of foreign matter such as dust. In addition, as mentioned above, the opening and closing portion 120 with the inclined portion 122 and the rotation center portion 112 supported at the center of the main plate 110 are inserted into the through hole 520 of the outlet at the same time. The entry of the connection terminal 420 is allowed, but a material such as a metal chopstick through a through hole 520 of only one outlet, and a material having a diameter of an end smaller than the through hole 520 of the outlet (hereinafter, typically chopsticks) When the inclined portion 122 is pressed, it is possible to prevent the main plate 110 from rotating.

However, when the chopstick simultaneously presses the opening / closing part 120 through all through-holes 520 of the outlet, the end of the chopstick entering the through-hole 520 of the outlet along the entry direction I is connected to the plug terminal. Like the end of the, since the sliding opening and closing portion 120 sliding along the inclined surface of the opening and closing portion 120 can cause the electric shock accident by the insertion of the chopsticks. That is, only the inclined portion 122 and the rotation center portion 112 provided as a configuration of the safety device of the outlet cannot prevent chopsticks from being simultaneously inserted through the through holes 520 of each outlet.

In fact, about 10% of electric shock accidents are accidents caused by young children in the home, so curious young children who are not aware of precautions in using outlets or electronic devices can use only one chopstick or two chopsticks. There is a need for a reliable way to prevent Eden from entering the through hole 520 of the outlet.

Therefore, in order to prevent electric shock accidents of young children who attempt to insert the chopsticks into the through-holes 520 of the outlet, it is prevented that the chopsticks enter the all through-holes 520 as well as some through-holes 520 of the outlet. It is important to do.

The opening and closing portion 120 of the outlet safety device 100 according to an embodiment of the present invention has an inclined surface with respect to the rotational direction of the main plate 110 on the side where the connection terminal 420 of the plug enters, as described above. The formed inclined portion 122 may be provided.

As shown, the non-slip portion 123 formed on the inclined portion 122 makes contact with the end of the plug's connecting terminal 420, and at the inclined portion 122, the end of the plug's connecting terminal 420 slides. It is allowed, but may be provided to contact the end of the chopsticks and not allow the end of the chopsticks to slide on the inclined portion 122.

That is, the non-slip portion 123 is configured to allow the connection terminal 420 of the plug to rotate the main plate 110, but is preferably configured so that the chopsticks do not rotate the main plate 110.

Therefore, as illustrated in FIGS. 11 to 13, the non-slip portion 123 formed on the inclined surface of the inclined portion 122 may be formed of a plurality of protrusions protruding from the inclined surface of the inclined portion 122.

In general, the connection terminal of the outlet is about 5mm in diameter and the end is formed to be round. On the other hand, representatively, chopsticks are formed such that their diameters are smaller than the diameters of the connection terminals of the outlets and their ends are angled. The shape difference between the ends is formed according to each application, and the ends of the connection terminals of the outlets are provided to facilitate the insertion of the plugs into the through-holes of the plug, and the ends of the chopsticks are shaped (such as side dishes). It is because it is provided to facilitate picking up. That is, when the end of the chopstick is formed thickly or is provided in a round shape, it is difficult to pick up the object with the end of the chopstick, so the end of the chopstick is relatively smaller in diameter than the end of the connection terminal of the outlet and the outer shape of the end is formed at an angle. It is inevitable.

Considering the shape of the connection terminal of the outlet and the end of the chopstick, the non-slip portion 123 makes the end portion of the chopstick to be inclined by making the edge of the chopstick end through the spaced apart between the plurality of protrusions and the protrusion 122 To prevent slipping on the inclined surface, the end of the connection terminal of the outlet can be made to slide on the inclined surface of the inclined portion 122.

At this time, it is preferable that the protrusion protrudes about 0.5 to 1 mm from the inclined surface of the inclined portion 122, and is disposed at equal intervals between the protrusion and the protrusion so that the end edge portion of the chopstick is caught between the protrusion and the protrusion.

The non-slip portion 123 may be provided by forming a plurality of grooves on the inclined surface of the inclined portion 122 in another embodiment. Although not shown in the drawings, the end edge portion of the chopsticks can be caught in the groove formed on the inclined surface of the inclined portion 122 so that the end portion of the chopstick does not slip on the inclined portion 122.

The groove provided on the inclined surface of the inclined portion 122 may be formed to be larger than the end of the chopstick so that the end of the chopstick is completely inserted into the groove, but substantially the inclined portion 122 corresponds to the end face of the connection terminal of the outlet Because the area is very small in size, the size of the grooves that can be formed in the inclined portion 122 is limited, and even if only the edge of the chopstick end is hung in the groove provided in the inclined portion 122, the end of the chopstick is inclined portion 122 ) To prevent slipping. Therefore, the size of the grooves provided on the inclined surface of the inclined portion 122 can be achieved by forming a plurality of sizes smaller than the cross section of the chopsticks.

The non-slip portion 123 is another embodiment, as shown in FIG. 14, may be provided by forming a step along the inclined direction of the inclined portion on the inclined surface of the inclined portion 122. That is, the non-slip portion 123 is formed so that the inclined surface of the inclined portion 122 is stepped along the inclined direction, so that the edge of the chopstick end is caught on the stepped jaw formed on the inclined surface.

15 is a view showing a state in which a seating part is formed in an opening and closing part according to an embodiment of the present invention.

According to an embodiment of the present invention, as shown in the drawing, the opening and closing part 120 of the outlet safety device 100 protrudes from the edge portion of the opening and closing part 120 on the side where the connection terminal 420 of the plug enters. The inclined portion 122 having an inclined surface with respect to the rotational direction of the main plate 110 and a lower portion than the inclined portion 122 (that is, the seating portion may be disposed farther from the through hole of the outlet than the inclined portion) 126 ) May be provided.

By forming the seating portion 126 lower than the inclined portion 122, the end of the plug's connecting terminal 420 is lower than the seating portion 126 when the plug's connecting terminal 420 enters the through hole 520 of the outlet. The inclined portion 122 may be first contacted, and then the main plate 110 may be rotated while the plug connection terminal 420 enters the inclined portion 122.

Then, by forming the inclined portion 122 on the edge of the opening / closing portion 120 in a region smaller than the seating portion 126, the end portion of the chopstick having a smaller area than the end portion of the connecting terminal 420 of the plug has a through hole in the outlet ( When inserted into the 520, it may lead to pass the inclined portion 122 and enter the seating portion 126.

Accordingly, the opening / closing part 120 provided with the inclined part 122 and the seating part 126 is connected to the plug of the plug having a diameter corresponding to the through hole 520 of the outlet, and the inclined part 122 is provided. On the other hand, while being inserted into the inside of the outlet, chopsticks having a smaller end area than the connecting terminal 420 of the plug can be prevented from being inserted into the inside of the outlet by allowing the seating portion 126 to enter.

Then, by changing the inclination direction of the inclined portion 122 and the inclined direction of the seating portion 126, when the chopstick presses the seating portion 126, the main plate 110 in the opposite direction in which the through hole 520 of the outlet is opened ) Can be rotated so that the end of the chopstick is not inserted into the outlet.

In addition, although not shown in the drawing, a haunch portion may be provided at a boundary between the inclined portion 122 and the seating portion 126.

As the inclined portion 122 protruding from the opening / closing portion 120 comes into contact with the connection terminal 420 of the plug, stress may be concentrated at the boundary between the inclined portion 122 and the seating portion 126. By being formed at the boundary between the 122 and the seating portion 126, damage to the inclined portion 122 can be prevented.

 An inclined surface may be formed in the haunched portion such that the end of the chopstick that first comes into contact with the inclined portion 122 slides along the inclined surface of the haunched portion to the seating portion 126.

Meanwhile, it has been described above that the bottom surface may be spaced apart from the bottom of both ends of the main plate 110 for rotation of the main plate 110. At this time, if any one end of the main plate 110 is further pressed, the gap D of the more pressurized side may be larger as the main plate 110 is inclined. As the gap D increases, the end of the chopstick becomes easier to dig between the gap D, so that the end of the chopstick makes it easier to press the inclined portion 122, and eventually the main plate 110 by the end of the chopstick. A situation arises that allows to be rotated.

Accordingly, as shown in FIGS. 18 and 19, the inclined portion 122 is close to the rotation center portion 112 so as to minimize the expansion of the gap D in the region where the inclined portion 122 is formed. (120) It is preferable to be formed in the edge region.

At this time, the seating portion 126 may be formed in the central portion of the opening / closing portion 120 to induce the end of the chopstick to enter the seating portion 126. And, by forming the seating portion 126 in a concave or concavo-convex formation in the seating portion 126, it is possible to prevent the end of the chopstick contacting the seating portion 126 from slipping.

18 and 19, on the side where the connection terminal 420 of the plug enters, the departure preventing portion 128 protrudingly formed at the edge region of the opening / closing portion 120 far from the rotation center portion 112 May be further included. That is, the departure preventing portion 128 may be formed in the edge region of the opening / closing portion 120 spaced apart from the inclined portion 122 with the seating portion 126 formed in the center portion of the opening / closing portion 120 interposed therebetween. The separation preventing portion 128 thus formed can reliably prevent the end of the chopstick from being inserted into the outlet through the gap D.

The departure preventing portion 128 may be formed on all or part of the edge of the opening / closing portion 120 except for the region where the inclined portion 122 is formed. When the departure preventing portion 128 is formed on a part of the edge of the opening / closing portion 120, it is preferable to be provided in the form of an arc having a central angle of 140 degrees to 150 degrees, which is between the departure preventing portion 128 and the inclined portion 122 The purpose is to prevent the end of the chopsticks from passing through the spaced apart.

In addition, through the through-hole 520 of the outlet, so that only the inclined portion 122 and the seating portion 126 is exposed, or only a portion of the inclined portion 122, the seating portion 126 and the release preventing portion 128 is exposed. And, all or part of the departure preventing portion 128 may be formed so as not to be exposed through the through hole 520 of the outlet. That is, when the connection terminal 420 of the plug enters the through hole 520 of the outlet, the departure prevention portion 128 does not interfere with the entry of the connection terminal 420 of the plug, the departure prevention portion 128 is an outlet It may be formed at a position outside the corresponding range of the through-hole 520.
