Patent ID: 8382499

Claim:
A power connection apparatus which is constituted of a power socket including an electrode portion and a power plug including terminals electrically connected to the electrode portion, the apparatus comprising: an engagement portion formed in the power socket; and a handle including a grip portion at one end thereof and an abutment portion at the other end, a pivoting portion positioned between the ends being rotatably attached to the power plug, wherein the handle includes engaging claw positioned at the pivoting portion or on the side of the grip portion from the pivoting portion to be disengageably engaged with the engagement portion of the power socket, when the handle is rotated in a direction in which the grip portion comes close to the power socket in a state where the terminals of the power plug are connected to the electrode portion of the power socket, the engaging claw disengageably engages with the engagement portion, when the handle is rotated as much as a predetermined angle or more from the state in a direction in which the grip portion comes away from the power socket, the engagement between the engaging claw and the engagement portion is released, and when the handle is further 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 to release the connection between the electrode portion and the terminals such that there is no physically-direct contact therebetween, wherein when the power plug is pressed onto the power socket in such a direction as to connect the terminals to the electrode portion in the state where the handle is rotated to such an angle that the handle is at substantially right angles to the power socket, and wherein the power plug fits into a seal member provided around the electrode portion, the seal member tentatively holding the power plug in a state where the electrode portion is neither electrically nor physically connected to the terminals.
