The present invention relates to a safety plug for an electrical outlet, and more particularly, to a safety plug for an electrical outlet and a safety plug for both electrical outlets that can be used as the electrical outlet.

In general, an outlet is a device that is connected to an electrical indoor wiring and inserts a plug in order to supply power to electrical appliances, and is a buried outlet installed on the floor or wall of a building and movably arranged in a home or office to provide other electrical appliances. There is a multi-outlet that allows you to connect and use the product.

In the basic structure of such an outlet, a plug insertion groove into which a plug body can be inserted is formed on one side of a body, and a terminal insertion groove into which a plug terminal can be inserted is formed on a bottom surface of the plug insertion groove. The insertion path of the plug is guided by the plug insertion groove of the outlet, and as the plug terminal is inserted into the terminal insertion groove of the outlet, electrical terminals inside the outlet are connected to allow current to flow toward the plug.

These outlets are generally formed in such a way that the plug insertion groove and the terminal insertion groove are always exposed to the outside, and since there is no protective equipment in the terminal insertion groove, curious young children may insert a conductor such as chopsticks into the terminal insertion groove. In the case of insertion, a problem such as leading to an electric shock accident has occurred.

In order to solve this problem, a safety device that blocks insertion of tools other than the rated plug is provided. Briefly, this safety device is equipped with a safety cover inside the outlet, and the plug insertion hole of the safety cover is installed. An inclined portion for sliding guide is provided on one side, and when two plug terminals press the inclined portion of the safety cover at the same time, the safety cover slides and the plug insertion hole is opened.

According to the safety device of the conventional outlet, although the connection terminal is always kept closed by the safety cover, when children insert tools such as chopsticks at the same time, the inclined part is pushed, and accordingly, the safety cover Since the connection terminal is opened and connected to the tool while sliding, there is a problem of causing an electric shock accident.

In order to solve this problem, a safety device having a cover member for opening and closing the plug connection terminal, an elastic member for elastically supporting the cover member, a sliding part formed with a curved locking groove, and a step part has been proposed.

However, conventional safety devices, including the above-mentioned safety device, have many problems in terms of workability and economy when installed in a buried outlet, such as the need to install the above-mentioned safety device after removing the previously installed outlet.

In addition, when installing the multi-plug or the like, the main body of the multi-plug must be replaced and installed on each plug portion of the multi-plug, so there is a problem in terms of workability and economic feasibility when installed in the existing multi-plug.

Hereinafter, with reference to the accompanying drawings, a safety stopper combined with an electrical outlet according to the present invention will be described in detail as an embodiment.

As shown in FIGS. 1 to 8, the electrical outlet combined safety stopper 1 according to the present invention includes a cover part 10, a base frame 20, an on/off block 30, and an insertion protrusion 40 ) is composed of.

The cover part 10 is formed to correspond to the shape of the base frame 20 and is configured to cover the base frame 20 . An opening 11 is formed in the cover part 10 at a position corresponding to the position where the inclined part of the safety block described later is formed so that the insertion rod of the plug can be inserted.

In addition, a hole is formed in the cover part 10 such that an on/off protrusion of an on/off block, which will be described later, protrudes above the upper surface of the cover part.

In addition, as shown in FIG. 1, the cover portion has a concave portion corresponding to the ground terminal hole of the plug. In addition, as shown in FIG. 5, fastening protrusions 50 protrude outward from both sides of the cover part. As shown in FIG. 6 , the fastening protrusion 50 is inserted into a concave groove of an electrical outlet already installed in a building or the like so that the safety stopper 1 can be stably fastened to the outlet.

The base frame 20 is provided below the cover part.

The base frame 20 is provided with a safety block 21, an elastic part 25, and an on/off block 30.

The safety block 21 includes a blocking portion 22 and an inclined portion 23 . The blocking part 22 is formed on the bottom surface of the incision formed in the safety block 21, and is formed at a position corresponding to the position of the insertion protrusion. The blocking portion 22 is formed to be narrower than the diameter of the plug insertion rod and larger than the diameter of a sharp tool such as chopsticks, so that the insertion rod of the plug is guided by the inclined portion, and a sharp tool such as chopsticks is guided to the blocking portion. It is configured to block insertion by

Around the blocking portion 22, the inclined portion 23 is formed in a horseshoe shape or a curved shape when viewed from a plane. The inclined portion 23 is formed to be inclined downward toward the outside, and when the insertion rod of the plug is inserted, the insertion rod of the plug is guided by the inclined portion and pressed downward, and the pair of safety blocks formed with the inclined portion (21) are made to slide toward each other so as to become closer.

The safety block 21 slides by the elastic part 25. The elastic part 25 is formed by, for example, an elastic spring, and the safety block 21 has an accommodating part 24 accommodating one end of the elastic part.

As shown in FIG. 2, the accommodating part 24 is formed by cutting a part of the safety block 21. In this embodiment, as shown in FIG. 7, the receiving portion 24 is preferably formed by cutting into a semicircular shape when viewed in cross section.

When inserting a plug to use a home appliance, the grounding part formed next to the plug and the grounding part attached to the existing outlet do not make enough contact. It is a safety device that reduces the grounding area by the height of the safety stopper.

Therefore, it is necessary to reduce the size of existing accessories. If the cylinder type (i.e., the cross section is circular), which is the spring insertion shape installed in the existing accessory, is left as it is and only the size is reduced, the thickness of the accessory becomes too thin, making it difficult to assemble by inserting the elastic part into the elastic part insertion hole installed in the sliding accessory. It has a very tricky downside.

In order to overcome this disadvantage, in the present embodiment, the incision of the receiving part formed to insert the elastic part is configured to have a semicircular cross section.

As shown in FIG. 8, the receiving portion 24 formed as described above can be easily installed and assembled. That is, after installing the safety block 21 on one side, inserting the elastic part into the semicircular opening of the receiving part, slightly contracting the opposite side of the elastic part with one hand, and then removing the remaining accessories, the safety block on the other side. When inserted in a form covering from above, assembly can be facilitated even if the size of the safety block is so small that it is difficult to hold in the hand.

In addition, as shown in FIG. 1, the base frame has a concave portion corresponding to the ground terminal hole of the plug. In addition, as shown in FIG. 5, fastening protrusions 50 protrude outward from both sides of the base frame. As shown in FIG. 6 , the fastening protrusion 50 is inserted into a concave groove of an electrical outlet already installed in a building or the like so that the safety stopper 1 can be stably fastened to the outlet.

An insertion protrusion 40 protrudes from the lower portion of the base frame 20 and is installed.

The insertion protrusion 40 protrudes from the bottom of the safety stopper and is inserted into an insertion terminal of an electrical outlet already installed in a building.

The insertion protrusion 40 has a hollow portion for accommodating the insertion rod of the plug, and the insertion rod of the plug may be inserted into the hollow portion.

A conduction opening 41 is formed at one side of the hollow portion, and is configured to electrically communicate with the outlet by guiding the insertion rod of the plug inserted into the hollow portion to the terminal insertion groove of the outlet.

The on-off block 30 is installed in the base frame 20 .

The on/off block 30 is formed to be movable while seated on the base frame 20 . The on/off block 30 has a seating portion 31 inserted into the movable groove 20a formed in the base frame, and on both sides of the seating portion 31, insertion portions 32 integrally formed with the seating portion 32 are provided. ) is provided.

The on/off block 30 further includes an on/off protrusion 33 protruding upward to protrude above the upper surface of the cover part.

When the user moves the on/off protrusion 33 back and forth, the on/off block 33 integrally formed with the on/off protrusion 33 moves the seating portion 31 forward and backward along the moving groove 20a. Thus, the insertion part 32 can be inserted between the pair of safety blocks 21.

When the user moves the on/off protrusion 33 to an on mode, the on/off block 30 is inserted between the pair of safety blocks widened by the elastic part to prevent movement of the safety block. limit

When the user moves the on/off protrusion 33 to an off mode, the on/off block 30 separates between the pair of safety blocks and the safety block 21 is involved in the insertion of the plug insertion rod. Sliding movement is possible by

Accordingly, it is possible to easily and safely prevent the insertion of objects into electrical outlets by preventing the insertion of foreign substances such as chopsticks as well as plugs by the operation of the on/off block, thereby preventing safety accidents from occurring.

On the other hand, as shown in Figure 4a, the on-off block of the present invention can be configured to be turned on and off by a magnet.

An on/off block 30' shown in FIG. 4 is disposed between the pair of safety blocks 21. Like the on-off block 30, the on-off block 30' is disposed between the pair of safety blocks 21, and the upper end protrudes outward from the cover part like the on-off protrusion 33 or It may be formed on substantially the same surface as the upper surface of the cover unit.

The on/off block 30' includes a plate or block formed of a magnet, so that a user can approach a magnet from the outside and be drawn to the outside of the cover part by magnetic force.

As shown in FIG. 4B, the on/off block 30' includes a magnet block body 301 and a stopper 302. The magnet block body 301 is formed of a metal material that responds to the magnetic force of the magnet, and is installed at a position out of the sliding movement path of the pair of safety blocks 21. The stopper 302 is formed larger than the magnet block body 302 and is located between the sliding movement paths of the pair of safety blocks.

In this way, when the user draws the on/off block 30' by approaching the magnet in a state where safety is ensured by inserting the safety stopper into the outlet, the stopper 302 operates as shown in FIG. 4D. It is located on the sliding movement path of the block 21 and blocks the movement of the safety block, so that the safety block is blocked from sliding and thus inserting the plug itself can be blocked.

When the on/off block 30' is pressed from the outside of the cover part, as shown in FIG. 4C, the stopper 302 is positioned out of the sliding movement path of the safety block 21, thereby preventing the safety block ( 21) into a sliding movable state, and then the plug can be inserted and used.

This embodiment only clearly shows a part of the technical idea included in the present invention, and variations and specific examples that can be easily inferred by those skilled in the art within the scope of the technical idea included in the specification of the present invention It is obvious that all are included in the technical spirit of the present invention.
