Description

{SAFETY CAP FOR ELECTRIC POWER PLUG}

The present invention relates generally to a safety cap for a power plug, and more particularly, to a safety cap which can be used at all times even when the power plug is connected to an outlet, and is firmly fixed to the inner wall of the outlet, thereby effectively preventing dust, The present invention relates to a power plug safety protection cap which effectively blocks harmful electromagnetic waves and protects the power plug.

Various safety receptacles have been used to prevent the use of electricity, dust, and foreign objects. However, safety caps have not been installed to prevent the danger of being plugged in and plugged in. Generally, many electric outlets are being used as the dependency of electric and electronic products in industrial sites, construction sites, offices, homes and the like increases. The outlet is used in various forms ranging from a fixed form to the wall of a building to a multi-tap, which is a removable outlet that allows plugging in multiple power plugs.

On the other hand, if you use an electric appliance such as an office, a factory, a restaurant, etc. that is always in use for computers and printers, if you plug the power plug into an outlet, There are many.

However, when the outlet is exposed to such a state for a long time, dust and foreign matter in the office are accumulated in the outlet. These dusts and foreign matter can accumulate in the insertion slot of the outlet where the power plug is plugged, which may cause electric shock or short circuit. Especially, when the power plug is connected to the power source, electric energy is generated, harmful electromagnetic waves are emitted, and dust in the outlet is exposed to safety and fire accidents due to electric leakage occur frequently. The risk of such electric shock and short- The probability of occurrence in the condition may be high.

First of all, such a risk is higher because a lot of dust accumulates in the outlets installed in the outermost places and is difficult to be managed by the user in a place where the first place such as an industrial site occurs, a restaurant or a home.

As described above, regarding the safety in the socket, it is recognized that the inflow of dust, foreign matter, water and the like is a serious problem in electric safety, but a solution is not proposed.

The application No. (20-2016-0007475) discloses a safety cap function in the state where the power plug is plugged into an outlet. However, there is a limit in which the ungrounded plug can be used only in a thin cross-sectional shape. In addition, the troubles of detachment and separation at the time of separation and the risk of loss were inevitable.

Therefore, even if any type of power plug is used at any place exposed to dust in an industrial site, a construction site, an office, a home, etc., a safety cap capable of preventing inflow of dust and foreign matter, .
