DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug remover used for removing a power plug connected to an outlet, and more particularly to a plug remover having a dustproof effect when the power plug is used.

[0002]

2. Description of the Related Art If dust or the like adheres to an exposed portion of a blade (insertion portion) of a power plug inserted into an outlet, it is possible that a short circuit may occur between the blades, which may cause a fire or a fire. Have been. Therefore, in order to prevent dust and the like from adhering to the exposed portion of the plug, conventionally,
A fire prevention power plug for covering the blade of the plug (see JP-A-8-264225) and a protective structure for the power plug (see JP-A-8-264225)
8-264225).

In the former power plug, the base of the blade of the power plug is covered with an insulating material. Even if dust or the like adheres between the blades, the insulating material prevents leakage between the blades. .

In the latter protection structure, a bellows-shaped cover is provided on the blade of the power plug so as to be extendable, and the bellows-shaped cover is connected to a nonflammable cover fixed to the case of the power plug.

[0005]

However, in the conventional device for covering the blade of the power plug, even though the leakage of the power plug blades can be prevented, the power plug that is tightly inserted into the outlet is pulled out. I couldn't help in the event.

[0006] That is, the reason why the dust or the like adheres to the blade of the power plug and the leakage occurs is partly because the blade is loosely inserted and is easily pulled out from the outlet. Therefore, if it is difficult to remove the blade, it is possible to prevent the blade from being exposed. Therefore,
It is effective to make the blade as hard as possible to be removed from the power plug where dust and the like are likely to adhere before attaching the leakage prevention cover.

[0007] However, since the power plug inserted in such a state that the blade is difficult to be removed requires power when removing the power plug, it is difficult for a weak woman or child to easily remove the power plug.

Therefore, the present invention has been created to solve the above-mentioned problem, and it is possible to easily remove a plug inserted in a state where the blade is hardly pulled out.
Moreover, even if the plug blade is exposed,
An object of the present invention is to provide a plug remover which has an effect of preventing leakage of electricity by preventing adhesion of cotton dust and the like.

[0009]

In order to achieve the above-mentioned object, a first means of the present invention is provided between a case P1 of a power plug P and an outlet Q, and a case P of the power plug P is provided.
