An improved polarity fuse plug. The plug includes an outer shell, an inner plug, 2 electric conductors, a concave shaped butterfly plate and a water proof chip. The outer shell is a flat stand and the inner plug holds each electric conductor separately. One of the electric conductors is connected to the fuse and the end of the other electric conductor is connected to the power cable. There is a concave shaped flume on the side of the fuse box and inside of the box has the concave shaped butterfly plate plugged onto it. The end of the concave shaped butterfly plate is connected to the power cable so as to avoid exposing the power cable when the fuse box is opened. Inside the plug are 2 power cables and a cable separation boad installed in order to strengthen the insulation. Also both the outer shell and the inner plug that are facing each other have a convex slot in order to hold a water proof chip to prevent water leaking in and to prevent leakage of high voltage to secure safety.
