Abstract
A waterproof power plug includes a mounting frame, first and second conductive terminals, a fuse, and a fuse cover which are mounted inside the mounting frame. The fuse is electrically connected to the second conductive terminal. The mounting frame is provided with a mounting groove for exposing the fuse, and the fuse cover is mounted in the mounting groove to cover or expose the fuse. The power plug further includes a housing opened with a window for slidably operating the fuse cover, and a waterproof cover is mounted in the window. Therefore, the fuse cover is arranged on the mounting groove and the waterproof cover is further covered on the fuse cover, which provides multiple waterproof protections. The power plug has a good sealing performance and waterproof performance, which also helps to improve the overall waterproof performance and work safety of the string light with the power plug.
