Description

Plug {PLUG}

In general, the plug 10 for supplying power to a home appliance has a main body 12 having a gripping portion formed to be easily detachable from an outlet as shown in FIG. 1, and a positive electrode and a negative electrode are partially embedded in the main body. It is composed of two connection terminals 14 connected to protrude to the front.

The guide pin 16 of the plug 10 is guided to the guide groove 26 of the power outlet 20 and inserted into the concave groove 22 of the power outlet 20 so that the connection terminal 14 is connected to the power source. It is connected to the power line of the outlet 20.
In addition, a pair of grounding terminals 28 provided at predetermined intervals protrude from the side of the recess 22 in the recess 22 of the power outlet 20, and thus, the pair of grounds on the side of the plug 10. The metal piece 18 for connecting correspondingly to the terminal 28 is provided.

However, the plug and the power outlet of this structure, as shown in Figure 2, because the plug is inserted into the recess of the power outlet and there is a space between the plug and the power outlet, foreign matter or water in particular between the space Is more likely. These foreign objects or water can cause short circuits and short circuits, as well as serious safety accidents such as fire and electric shock.

In particular, as household appliances used in bathrooms and kitchens, such as bidets and dryers, are becoming more common these days, such risks increase. In addition, the same risk exists in the case of electrical appliances used outdoors.

The present invention is devised to solve the above problems, the object of the present invention is that the plug itself to cover the recess of the power outlet when the plug is inserted into the recess of the power outlet, the plug It is to prevent foreign matter or water from penetrating into the space between the power outlet and the safety accident such as fire or electric shock.

Another object of the present invention is to provide an economically efficient plug that does not require a separate device or component in the electrical outlet in order to prevent such a safety accident.

The above and other objects and advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

A plug according to the present invention for achieving the above object is a plug for supplying power to home appliances by being inserted into the recessed groove of the power outlet is connected to the power line, the plug is a gripping portion to facilitate attachment and detachment from the power outlet The main body is formed of two connection terminals protruding toward the front by connecting the positive electrode and the negative electrode with a part embedded in the main body, the front surface of the main body has a diameter of a size that is inserted into the concave groove of the power outlet A wing portion having a diameter of a size covering a bottom portion and a recess of the power outlet is formed by forming a step.

According to another aspect of the present invention, when the connection terminal of the plug is connected to the power line of the power outlet, the wing portion to cover the recessed groove of the outlet characterized in that it prevents foreign matter or water from penetrating into the recessed groove do.

According to another aspect of the present invention, the plug is characterized in that the hook is further formed on the main body so as to be more easily removable from the power outlet.

As described above, the plug according to the present invention is formed with a bottom portion inserted into the concave groove of the power outlet and the wing portion covering the concave groove of the power outlet, and the bottom portion and the wing portion is formed stepped By forming the plug, when the plug is inserted into the power outlet, the wing portion covers the concave groove, and the foreign matter or water can be prevented from being inserted into the concave groove.

In particular, in order to prevent the occurrence of safety accidents such as fire or electric shock due to foreign substances or water penetrating into the recessed grooves, the safety structure is changed by changing the structure of the plug itself without adding a separate structure or device to the power outlet. It is economical because it is prevented.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. These examples are only intended to describe the present invention in more detail, it will be apparent to those of ordinary skill in the art that the scope of the present invention is not limited by these examples. In addition, the components unnecessary for the understanding of the present invention are omitted for the convenience of description so that the focus of the present invention is not blurred.

Figure 3 is a perspective view of the plug according to the present invention, Figure 4 is a side view, Figure 5 is a perspective view when the plug is plugged into a power outlet.

Plug 10 according to the present invention is the front surface of the main body 12 of the plug 10 is formed of a bottom portion 30 and the wing portion 40. The bottom portion 30 is a portion inserted into the concave groove of the power outlet as in the conventional plug, and the wing portion 40 is a portion covering the periphery of the concave groove. That is, the size of the diameter of the wing portion must be larger than the diameter of the concave groove, the size of the diameter of the bottom portion should be smaller than the diameter of the concave groove.

The bottom part 30 and the wing part 40 forming the front surface of the main body have a step h corresponding to the depth of the concave groove.

Therefore, when the plug is plugged into a power outlet as shown in FIG. 5, the bottom portion 30 is inserted into the recessed groove so that the connecting terminal is connected to the power line, while the wing portion 40 covers the recessed groove. . By doing so, it is possible to effectively prevent foreign matter or water from seeping into the recess when the plug is inserted into the power outlet.

The maximum size of the diameter of the wing 40 is enough to not interfere with the wing of the neighboring plug when the power outlet is a multi-tap.

6 is a perspective view of a plug according to another embodiment of the present invention.

The plug according to the present embodiment is exactly the same as the plug shown in FIG. 3, and the only difference is that the plug further includes a hook 50 formed in the plug body so that the plug can be easily detached from the power outlet. have.

In the above description of a specific preferred embodiment of the present invention, the present invention is not limited to the specific embodiment described above, in the technical field to which the present invention belongs without departing from the spirit of the present invention claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are within the scope of the claims.
