Abstract: A plug with a replaceable fuse is provided. The plug includes an outer housing, an inner core, a pair of prongs and a pair of conductive cords. The outer housing includes a fuse uninstall button opening and an inner core install opening. The inner core is installed into the outer housing through the inner core install opening, and the inner core includes a fuse socket and a fuse uninstall button. The fuse socket has an uninstall opening. When it is intended to replace the fuse, the fuse uninstall button is pressed from the fuse uninstall button opening, the fuse is ejected or pushed out of the fuse socket by one end of the fuse uninstall button extending to the uninstall opening. When the fuse uninstall button is not pressed, the fuse uninstall button restores to the original position, such that a new fuse is installed into the fuse socket.

Abstract: A plug with a self-recovering current limiting fuse includes a fuse, a pair of prong, a pair of conductive cords, the self-recovering current limiting fuse, an outer housing, and the inner core. The outer housing comprises a fuse uninstall button opening and an inner core install opening. The inner core installed into the outer housing through the inner core install opening comprises a fuse socket, a fuse uninstall button, a rectifier, and a self-recovering current limiting fuse socket. Two ends of the self-recovering current limiting fuse are respectively coupled to the rectifier and the pair of the conductive cords. When an output current on the pair of conductive cords is larger than a rated current, the self-recovering current limiting fuse forbids the plug outputting the output current; and when the output current on the pair of conductive cords is smaller than the rated current, the plug outputs the outputting current.
