Abstract

Provided are a plug that makes it possible to readily connect a power supply such as a solar battery or fuel cell to an external load or system power and to enhance safety, as well as a power converter and power generating apparatus having the plug. The plug has a movable insulating member for covering the plug electrodes when the plug is connected to an outlet and for exposing the electrodes when the plug is not connected to the outlet. In another example of the plug, the plug has at least two electrodes and switches corresponding to respective ones of the electrodes, wherein the switches are opened (turned off) when the plug is pulled out of the outlet. In still another example of the plug, the plug has at least two electrodes and a switch that is opened/closed in dependence upon the state of the connection between the electrodes and the outlet. When the plug is connected to the outlet, the switch is closed (turned on) to thereby sense the fact that the plug has been connected to the outlet.
