  • Patent number: 8382499
    Abstract: There is disclosed a power connection apparatus which can secure connection between a power socket and a power plug with a simple constitution and which can simplify the connecting operation properties thereof. A handle rotatably attached to the power plug having terminals includes engaging claw disengageably engaged with engagement portion of the power socket having an electrode portion, an abutment portion which abuts on the power socket, and a grip portion. In a state where the handle is rotated to such an angle that the handle is at substantially right angles to the power socket, the abutment portion abuts on the power socket, thereby releasing connection between the electrode portion and the terminals or the like.
