Abstract

A piezoelectric element connection structure, a vehicle, and a piezoelectric element connection method are disclosed. This piezoelectric element connection structure includes: a body; a casing that include a bottom and is fixedly connected to the body so as to face the placing area for the board; a piezoelectric element that is placed on the bottom; and a coil wire that includes a winding shape, extends from the piezoelectric element toward the placing area for the board, and electrically connects between the piezoelectric element and the board.

Claims (20)

1 . A piezoelectric element connection structure comprising:

a body that includes a placing area for a board;

a casing that include a bottom and is fixedly connected to the body so as to face the placing area for the board;

a piezoelectric element that is placed on the bottom; and

a coil wire that includes a winding shape, extends from the piezoelectric element toward the placing area for the board, and electrically connects between the piezoelectric element and the board.

2 . The piezoelectric element connection structure according to claim 1 , further comprising:

a wire guide that includes a mortar-shaped opening formed therein and guides a terminal of the coil wire.

3 . A vehicle comprising the piezoelectric element connection structure according to claim 1 .

4 . A piezoelectric element connection structure comprising:

a body that includes a placing area for a board;

a casing that include a bottom and is fixedly connected to the body so as to face the placing area for the board;

a casing that includes a bottom facing a placing area of a board;

a piezoelectric element that is placed on the bottom;

a wire that extends from the piezoelectric element toward the placing area for the board and electrically connects between the piezoelectric element and the board; and

a wire guide that includes a mortar-shaped opening formed therein and guides a terminal of the wire.

5 . The piezoelectric element connection structure according to claim 4 , wherein

the wire is a coil wire that includes a winding shape.

6 . A piezoelectric element connection method comprising:

guiding a terminal of a coil wire including a winding shape to a top of a mortar-shaped opening of a wire guide while causing the terminal of the coil wire to be in contact with an inclined surface of the opening and passing the terminal of the coil wire through to a placing area for a board, the terminal extending from a piezoelectric element toward the placing area for the board and being on a side of the placing area for the board, the piezoelectric element being fixed to a bottom of a casing fixedly connected to a body including the placing area for the board; and

connecting the terminal of the coil wire to a wiring pattern of the board.
