an electric plug including a first plug terminal, a second plug terminal, a plug ground terminal, a pressing portion, a first terminal support portion, a second terminal support portion, and a plug hole, the plug ground terminal, the pressing portion, the first terminal support portion, the second terminal support portion being disposed in the plug hole, the pressing portion being disposed below the plug ground terminal and supporting the plug ground terminal from below, the first terminal support portion being disposed above the first plug terminal and supporting the first plug terminal from above, the second terminal support portion being disposed above the second plug terminal and supporting the second plug terminal from above; and
a power outlet including
a first fixed terminal,
a first fixed contact connected to the first fixed terminal,
a second fixed terminal,
a second fixed contact connected to the second fixed terminal,
a first movable contact facing the first fixed contact,
a first movable piece connected to the first movable contact,
a second movable contact facing the second fixed contact,
a second movable piece connected to the second movable contact,
a socket including a first insertion port configured to allow the first plug terminal to be inserted, a second insertion port configured to allow the second plug terminal to be inserted, and a third insertion port configured to allow the pressing portion to be inserted,
a first connection terminal disposed in the first insertion port, the first connection terminal being connected to the first movable piece,
