M253114 1 ......... 1 _ One, five, creation instructions (1) " " '--- [Technical field to which the new type belongs] * This creation is provided by —A power plug, especially a power plug with a safety device inserted on the power plug and socket to transfer power to electrical products. The power plug is provided with a safety device, and the safety device is used to make excessive current flow Blocking can not pass through the power plug, to prevent the power cord or electrical appliance α port from being burned by excessive current, so as to improve the safety of use. [Previous technology] 'Fuses should be installed at the mouth to prevent overload parts from burning. To date, there are still fires caused by small household appliances. There are nine reasons for this. One is the unstable supply voltage and excessive voltage. The electrical appliance with a high fuse is right 3. Grabbing > I, τ He loaded. i 余 Α 基. Knowing is dangerous, but this kind of situation rarely occurs. Neiqiu: lds are not countable, heat dissipation is poor, and the material is not resistant. The internal space is limited or it may be inferior to the soldiers ’soil. ^』 / Dish and fork When high temperature is generated inside, it may be caused by people & ^ fuse. When the electrical appliance is dazzled, the positive and negative bare wires or iron,!;: Insulation sheath; the enameled wire of the motor wire will cause the wire to ignite if the flame is ignited, which will cause a fire. ^ Some of the household appliances such as drinking machines, pots, buckets, electric fans and other electric appliances such as electric stoves, electric stoves, electricity, etc. have power in each house. ^ ^ The reason for the danger is the manufacturer. It is considered that an independent fuse or dagger is installed in the project, that is, a fuse is not installed in the appliance, such as: saving ^ Therefore, the load Γ is not tripped on the non-dissolving wire trip switch ... It is not overloaded and the small θ trips off. Happened. war
