  • Adapter with fuse and indicator and capable of being used as plug
    Patent number: 6592406
    Abstract: An adapter with a fuse and an indicator and capable of being used as a plug is disclosed. The adapter mainly includes an upper cover and a lower cover. Two parallel male terminals and two parallel female terminals are installed in the upper cover and lower cover. An indicator is connected to the two parallel female terminals. By controlling the contact of the indicator with the female terminals, the user can know whether the electric device is working in normal condition. Other than arranging in a fixing way, the two male terminals are rotatable by connecting them to a rotary unit. Besides, connecting pieces are used to connect the male terminals and female terminals. Two connecting pieces are connected through a fuse. By the action of the fuse, as the current of the fuse is overloaded, the fuse will melt and break so that the connected electric devices are protected.
