ABSTRACT:
A fused electrical plug for interconnecting appliances with a power supply (such as a conventional wall outlet). The plug includes at least neutral and positive terminal posts and may includes a ground terminal. The plug also includes a first body portion from which the neutral terminal post extends, the first body portion including a cavity for receiving a fuse. A second plug body portion carries the positive terminal post while a hinge secures the first and second plug portions for pivotal relative movement between an open position wherein the fuse receiving cavity is accessible in a closed position wherein the fuse receiving cavity is inaccessible. Electrical communication to the appliance is established via a fuse within the cavity and the positive terminal only when the first and second body portions are in the closed position. In a preferred embodiment, the first and second plug body portions are molded with the hinge being formed as a living hinge.
