Safety stopper for electrical outlets {SAFETY COVER ALSO USING AS POWER OUTLET}

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

In general, an outlet is a device for inserting a plug by connecting to an indoor wiring of electricity in order to supply power to an electric product. An outlet is a buried outlet installed on the floor or wall of a building, and is movably disposed at home or office to provide other electrical power. 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 the body of the plug can be inserted is formed on one side of the 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. An insertion path of the plug is guided by the plug insertion groove of the outlet, and the plug terminal is inserted into the terminal insertion groove of the outlet, so that the electric terminal inside the outlet is connected and current flows 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. When inserted, problems such as leading to an electric shock accident occurred.

To solve this problem, a safety device is provided that blocks tools other than the rated plug from being inserted. Briefly, this safety device is equipped with a safety cover inside the outlet, and the plug insertion hole of the safety cover is provided. An inclined portion for guiding sliding is provided on one side, and when two plug terminals simultaneously press the inclined portion of the safety cover, 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 maintained in a normally closed state by the safety cover, when children insert tools such as chopsticks at the same time, the inclined portion is pushed, and accordingly, the safety cover is closed. As it slides, the connection terminal is opened and connected to the tool, so there is a problem in that an electric shock accident is induced.

In order to solve this problem, a safety device including a cover member for opening and closing a plug connection terminal, an elastic member for elastically supporting the cover member, and a sliding portion and a step portion having a curved engaging groove have been proposed.

However, conventional safety devices, including the above-described safety device, have many problems in constructability and economic feasibility when installed in a buried outlet, such as having to install the above-described safety device after removing the pre-installed outlet.

In addition, when installing to a multi-plug, etc., the multi-plug body must be replaced and installed in each plug part of the multi-plug. Similarly, there was a problem in constructability and economic feasibility when installed in an existing multi-outlet.

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

As shown in Figures 1 to 8, the safety stopper (1) combined with an electrical outlet according to the present invention, the cover portion 10, the base frame 20, the on-off block 30, and the insertion protrusion 40 ) is included.

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 portion 10 at a position corresponding to the position where the inclined portion of the safety block is formed, which will be described later, so that the insertion rod of the plug can be inserted.

In addition, a hole is formed in the cover part 10 so that an on-off protrusion of an on-off block to be described later protrudes above the upper surface of the cover part.

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

The safety block 21 includes a blocking portion 22 and an inclined portion 23 . The blocking portion 22 is formed on the bottom surface of the cutout 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 inserted into the blocking portion. It is configured to block the insertion by the

In the periphery of the blocking portion 22, the inclined portion 23 is formed in a horseshoe shape or a curved shape in plan view. The inclined portion 23 is inclined downwardly 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 with the inclined portion are formed. (21) is moved by sliding toward each other so as to be close.

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

The accommodating part 24 is formed by cutting a part of the safety block 21 as shown in FIG. 2 . In this embodiment, as shown in FIG. 7 , the receiving part 24 is preferably formed by cutting in 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 sufficient contact. This is because the groundable part is reduced as much as the height of the safety stopper.

Therefore, it is necessary to reduce the size of the existing accessories. If the cylindrical shape (that is, the cross section) of the spring inserted in the existing accessory is kept as it is and only the size is reduced, the thickness of the accessory becomes too thin, and it is difficult to assemble it by putting the elastic part in the elastic part insertion hole installed in the slidable accessory. It has a very difficult drawback.

In order to solve this drawback, in the present embodiment, the cut-out portion of the receiving portion formed to insert the elastic portion is configured in a semicircular cross-section.

In addition, as shown in FIG. 5, the fastening protrusions 50 are formed to protrude outward from both sides of the base frame. As shown in FIG. 6 , the fastening protrusion 50 is inserted into the concave groove of an electrical outlet previously installed in a building, etc. so that the safety stopper 1 can be stably fastened to the outlet.

An insertion protrusion 40 is installed to protrude from the lower portion of the base frame 20 .

The insertion protrusion 40 protrudes under the safety stopper and is inserted into an insertion terminal of an electrical outlet previously 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 energization opening 41 is formed at one side of the hollow part, so that the insertion rod of the plug inserted into the hollow part is guided to the terminal insertion groove of the outlet so as to be in electrical communication with the outlet.

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

The on-off block 30 is movably formed while seated on the base frame 20 . The on-off block 30 has a seating portion 31 inserted into the moving groove 20a formed in the base frame, and both sides of the seating portion 31 have insertion portions 32 integrally formed with the seating portion. ) is provided.

The on-off block 30 further includes an on-off protrusion 33 which is formed to protrude upward so as 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 part 31 back and forth along the moving groove 20a. Thus, the insertion part 32 can be inserted between the pair of safety blocks 21 .

The on-off block 30 is inserted between the pair of safety blocks spaced apart by the elastic part when the user moves the on-off protrusion 33 to the on mode to prevent the movement of the safety block. limit
