Description

Safety outlet {SAFETY RECEPTACLE}

The present invention relates to a safety outlet, and more particularly, to a safety outlet in which a plug inserting opening of a receptacle is opened only when a power plug is plugged in, and a terminal inserting groove of the receptacle is opened only when a power plug is plugged.

Generally, when power is used in a home, office, or workplace, a plug connected to household electrical appliances and a wire is plugged into an outlet installed on a wall, or a plug is plugged into an outlet of a multi-tap connected to the outlet. An outlet plugged into the inside wall is usually installed at a position about 50 cm from the floor, and a multi-tap is used to plug into a wall outlet and extend to a desired area. The height of the wall-mounted outlet is easily visible to young children who do not know the danger of electricity. Curious young children are likely to get electric shocks by plugging a conductor into a wall outlet, such as a chopstick or an iron rod. .

In addition, in the case of an outlet, not only is the terminal insertion groove of the receptacle opened, but also the plug insertion opening into which the receptacle is inserted is opened, so that foreign matter such as dust accumulates on the plug insertion opening. It can be unsafe. For this reason, cleaning companies are removing the dust from the outlet by separating the outlet from the wall for safety reasons. Also, when cleaning the floor, it may cause electric shock accident as well as not being able to clean the water until the water runs dry by the operation of the earth leakage breaker due to the water splash on the outlet.

In order to prevent the danger of such electric shock or fire, a safety cover for a socket outlet has been developed as shown in Fig. The safety cover for an outlet is provided with a fixing pin 3 on the outside of the plug inserting port 2 of the receptacle 1 and a safety lid 4 is fastened to the fixing pin 3, The safety lid 4 is rotated so that the plug inserting opening 2 can be opened and closed.

However, in the conventional safety cover for a receptacle, when the plug is intended to be used, it is troublesome to insert the plug with one hand while opening the plug inserting opening 2 by turning the safety cover with one hand. In addition, when the plug is pulled out, the safety cover must be rotated to close the plug inserting port 2, and if it is used for a long time, the safety cover may not be able to close the plug inserting port 2 and may remain open.

The elevating means 80 includes a first magnet 81 mounted on the safety cover 20 and a second magnet 82 mounted on the plug inserting opening 11. [

The main body 10 is formed in a box shape of a hexahedron in which at least one plug inserting opening 11 is formed on one side. The main body 10 may be configured to be mounted on a wall, or may be a multi-tap used to extend a power line. The main body 10 is provided with an internal accommodating space, and a cable for connecting the power source is inserted. The lead-in cable is connected to the terminal 13 formed on the bottom surface of the plug inserting opening 11. The plug insertion port 11 is formed to have an inner diameter shape corresponding to the outer shape of the power float 1 so that the power plug 1 can be inserted. The plug insertion hole 11 is provided with guide rails 12 which are recessed at predetermined depths and extend along the height direction.

The safety cover 20 includes an ascending and descending member 30 which is formed so as to pass through the rotating hole 31 and is seated so as to be movable in the plug inserting opening 11, And a rotating plate 40 coupled to the rotating plate 40 and rotatably inserted into a rotating groove 33 formed on an inner surface of the lifting member 30, (50).

The ascending / descending member 30 is formed in the shape of a circular tube whose one side is open. The rotating hole 31 is passed through the end surface of the lifting member 30. A guide protrusion 32 slidable in the vertical direction is inserted into the guide rail 12 on the circumferential surface of the ascending / descending member 30. The guide protrusion 32 is formed at a position corresponding to the guide rail 12. [ It is preferable that they are formed at intervals of 180 degrees. At both ends of the guide projection 32, an inclined surface 32a is formed. The inclined surface 32a may be formed in a straight line or arc. It is easy to insert or separate the guide protrusion 32 formed on the lifting member 30 into the guide rail 12 by forming the inclined surface 32a and consequently the safety lid 20 is inserted into the plug insertion port 11, It is easy to attach or detach it.

The rotary plate (40) is inserted into the lifting and lowering member (30) and is formed in the shape of a circular tube whose one side is open. One side of the rotary plate (40) is exposed to the outside through the rotary hole (31). In addition, an insertion groove 42 is formed at one side of the body to be recessed at a predetermined depth so that a tool such as a coin or a one-way driver can be inserted. A through hole 41 through which the electrifying bar 2 is inserted is formed on one side of the rotary plate 40. A plurality of fixing protrusions 43 protrude from the other end surface of the rotary plate 40. A locking protrusion is provided at an end of the fixing protrusion (43). An enlarged groove 42a having an enlarged cross-sectional area is formed in the insertion groove 42. By forming the extension groove 42a in the vicinity of the inner bottom surface of the insertion groove 42, a locking protrusion is formed inside the insertion groove 42. When the tool is put on the locking protrusion and pulled, the safety lid 20 is inserted into the plug insertion port 11).

The bottom plate 50 is formed in a plate shape having an outer diameter corresponding to the inner diameter of the rotating hole 31. The bottom plate 50 is rotatably inserted into the rotation groove 33 formed on the inner surface of the lifting member 30. [ The bottom plate (50) is formed with a fixing groove (53) into which the fixing protrusion (43) is temporarily inserted. A first magnet (81) is mounted at the center of the bottom plate (50). A second magnet (82) is mounted inside the bottom surface of the plug insertion port (11). The first magnet (81) and the second magnet (82) are mounted so as to face each other with the same polarity so that a repulsive force is generated.

The through hole 51 is formed in the bottom plate 50 at the same vertical position as the through hole 41. The conductive bar (2) is inserted into the through hole (51). The bottom plate 50 is formed with a through-hole 52 into which a rotation protrusion 70 to be described later is inserted.

A bottom plate (50) is coupled to the rotary plate (40), and a receiving space is formed therein. An opening / closing member (60) is rotatably mounted in the accommodation space. A rotation hole is formed in the center of the opening and closing member 60 and the rotation hole is rotatably inserted into a rotation projection formed at the center of the rotation plate 40. [

The opening and closing member 60 is formed into a bar shape having a predetermined length so as to selectively open and close the energizing bar through- The rotation slope 61 is formed so as to be symmetrical with respect to the rotation hole formed at the center point of the opening and closing member 60. The rotating inclined surface 61 forms a right angle with respect to the longitudinal direction, and forms an inclined surface with its depth becoming deeper from one side to the other side along an arc centered on the rotating hole. Each of the rotation slopes 61 forms an inclined surface along the same rotation direction.

On the bottom surface of the plug insertion port 11, two rotation projections 70 are projected in pairs. The rotation protrusion 70 has a length enough to allow the end of the insertion port safety cover 20 to be in contact with the rotation slope 61 in a fully drawn state. It is preferable that the end of the rotation projection 70 is formed with a slanting projection surface 71 which is inclined corresponding to the rotation slanting surface 61. [ The end of the rotation protrusion 70 may be round or square in addition to the shape of the inclined projection 71 if the opening and closing member 60 can be rotated by pressing the rotation inclined surface 61. The opening and closing member 60 is elastically supported by the elastic member 61 as shown in Fig. The opening and closing member 60 maintains the position where the through hole 41 is closed by the elastic force of the elastic member 61. [

The operation of the safety outlet according to the first preferred embodiment of the present invention is as follows.

As shown in FIG. 3, when the power plug 1 is not used, a coin or a tool is inserted into the insertion port 42 to rotate the rotary plate 40 so that the through holes 41 and 51 are connected to the terminals 13 and Position it in the wrong position. When the rotary plate 40 is rotated as described above, an object passing through the through-holes 41 and 51 can never come into contact with the terminal 13. That is, even if the infant does not recognize electricity, even if chopsticks or the like are inserted into the through holes 41 and 51, it can not come into contact with the terminal 13, so that the electric shock accident can be prevented originally.

When the power plug 1 is to be used, as shown in FIG. 4, the rotating plate 40 is rotated so that the through-holes 41 and 51 are positioned so that the same vertical line as that of the terminal 13 is positioned. When the power plug 1 is inserted in this state, the current-carrying bar 2 can be inserted into the terminal 13 and electrically connected thereto. As described above, the receptacle formed at the position where the hands of the infant and the baby reach the hands can cut off the electric shock accident by rotating the rotary plate 40 as shown in FIG. 4, thereby improving the safety, The use of the outlet or the outlet of the house without the infant can be minimized by using the rotary plate 40 in a state where the rotary plate 40 is not rotated as shown in FIG. For example, if you have to plug in a plug that is always on the back of a TV set, it will cause considerable inconvenience.

As shown in FIG. 2, before the power plug 1 is inserted, the insertion port safety cover 20 is maintained in a withdrawn state by the repulsive force between the first magnet 1 and the second magnet 82. In the state in which the insertion port safety cover 20 is drawn out, foreign matter such as dust or water can not be drawn into the plug insertion port 11 because the plug insertion port 11 is kept closed.

The power plug 1 is inserted with the through holes 41 and 51 and the terminal 13 aligned as shown in Fig. As shown in FIGS. 2 and 5, the opening and closing member 60 is lowered in the insertion port safety cover 20 with the through-hole 41 closed. At this time, the force for pressing the power plug 1 must be larger than the repulsive force acting between the magnets.

The safety lid 20 is lowered by the pressing force of the power plug 1 so that the rotation projection 70 passes through the through hole 51 and touches the rotation slope 61 of the opening and closing member 60. [ The rotation projection 70 presses the rotation slope 61 to rotate the opening and closing member 60. [ The spring 62 is compressed as the opening and closing member 60 is rotated as shown in Fig. The opening and closing member 60 is rotated and the through hole 41 is opened. The opening and closing member 60 is returned to its original state by the elastic force of the spring 62 as shown in Fig. 5 and the through hole 41 is closed .

7, when the opening and closing member 60 is rotated by the rotation projection 70 and the through hole 41 is opened as shown in Fig. 6, the power supply bar 1 of the power plug 1 is inserted Hole 41 and the through-hole 51, and is inserted into the terminal 13. As shown in Fig. At this time, the energizing bar (1) is electrically connected to the terminal (13) to receive power.

Since the insertion port safety cover 20 keeps the plug insertion port 11 closed by the repulsive force between the magnets as described above, foreign matter is prevented from being drawn into the plug insertion port 11, and the power plug 1 is used It is possible to insert the energizing bar 2 into the terminal 13 while automatically opening the through holes 41 and 51 by pressing the inserting safety cover 20 with the power plug 1. This operation improves safety and usability.

Likewise, a safety outlet, which is a second preferred embodiment of the present invention, may be mounted on a main body 10 constituting a multi-tab that extends a power line as well as a receptacle on which the inlet safety cover 20 is mounted to the wall, have. Also, the rotary plate 40 and the bottom plate 50 may be rotatably mounted inside the lifting and lowering member 30 in a combined state, and the opening and closing members may not be mounted therein. The plug insertion port 11 is not provided with the rotation projection 70 and the through hole 52 is not formed in the bottom plate 50. [

As described above, the safety outlet according to the second preferred embodiment of the present invention is characterized in that the opening and closing member 60 is not mounted, the rotating projection 70 is not provided, and the through hole 52 is not formed in the bottom plate 50 The other structure and operation are the same as the safety outlet, which is the first preferred embodiment of the present invention.

As described above, the safety outlet, which is a preferred embodiment of the present invention, is mounted on the plug inserting opening 11 to prevent the foreign matter from being drawn into the plug inserting opening 11.

Further, the insertion port safety cover 20 is held at the inlet side of the plug insertion port 11 by the repulsive force of the magnet. Since the magnetic force of the magnet can be used for a long time, the life of the product is increased, and the magnet can be installed in a narrow mounting space in the main body 10.

Even if a chopstick or the like is inserted into the through hole 14 by rotating the rotary plate 40 so that the through hole 41 is located at a position displaced from the terminal 13, It does not. Therefore, electric shock accident of infants and children can be surely prevented.

In addition, the opening and closing member 60 may be rotated to open and close the through-hole 41, thereby preventing the occurrence of an electric shock accident by inserting chopsticks or the like.

Unlike the conventional method in which the opening and closing member 60 is formed so that the rotational slope is directed toward the through-hole 41 so that the conductive bar 2 of the plug can be rotated while being in contact with the plug, The opening and closing member 60 is rotated by the rotation protrusion 70 formed on the bottom of the plug insertion port 11 and the rotating slope is formed on the opposite side of the through hole 41, It is possible to prevent the foreign matter from flowing into the gap between the through holes 41. In other words, in the prior art, a rotating slope is formed so as to face the through-hole 41 side, and foreign matter can be introduced through a place where the rotating slope is formed. In the present invention, It is possible to prevent foreign matter from flowing into the gap between the opening and closing member 60 and the through hole 41. [

Generally, when the safety receptacle is installed on the wall, a bolt for fixing the safety receptacle main body 10 to the wall is formed mainly on the bottom surface of the plug inserting opening 11. [ When the bolt fastening portion is formed on the bottom surface of the plug inserting hole 11 and the safety lid 20 is formed in the plug inserting hole 11 so as not to be separated from the bolt fastening bolt for fixing the main body 10 to the wall Difficulties arise. Therefore, in the present invention, the safety cover 20 is detachably attached to the plug insertion port 11 of the main body 10, thereby solving this problem. That is, when the safety cover 20 is not installed in the plug insertion port 11 of the main body 10, the bolt is fastened to the bottom surface of the plug insertion port 11 of the main body 10 to fix the main body 10 to the wall Thereafter, the safety cover 20 is pushed into the plug insertion port 11. At this time, the guide protrusion 32 is easily inserted into the guide rail 12 due to the inclined surface 32a. When the safety lid 20 is to be detached from the main body 10, if the safety lid 20 is pulled outward while the tool is inserted in the extended groove 42a of the insertion groove 42, (20) is separated from the plug insertion port (11). At this time as well, the guide protrusion 32 is easily released to the guide rail 12 due to the inclined surface 32a.

The present invention is not limited to a structure in which the safety cover 20 is connected to the safety receptacle body 10 by a member of a type such as a spring or the like so that the safety cover 20 can not be separated, The safety cover is easily coupled to the plug insertion port 11 in a state in which the assembly is completed separately, and a feature of using the combination of the extension groove 42a and the inclined surface 42a, The operation of attaching or detaching the safety cover 20 to the plug insertion port 11 can be easily performed. This can solve the problem of not developing a receptacle with a safety cover covering only the plug insertion port 11 (the outlet market is a market with low cost competition, and it is a well-known fact that a difficult task must be solved by a minimum manufacturing company ), It is a very important feature when the outlet is installed on a wall.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
