MOUNTING METHOD FOR PIEZOELECTRIC SENSOR, ACTUATOR ARM, DISK DEVICE AND CONNECTION INSPECTION METHOD

Japanese Patent JP3208386

B2

PROBLEM TO BE SOLVED: To provide a piezoelectric sensor not allowing sacrifice of either workability in soldering of a lead wire to one electrode of the piezoelectric sensor or workability in joining and fixing of the other electrode to a prescribed member with an adhesive, allowing prevention of a short circuit between the electrodes by the protruding adhesive when joining and fixing the ground electrode of the piezoelectric sensor to an electroconductive portion of a measured member with the adhesive, and allowing easy inspection of electrical connection between the ground electrode and the electroconductive portion of the measured member.
SOLUTION: Two electrodes 18b, 18c of a piezoelectric sensor 18 are respectively composed of an electrode member suitable for soldering and an electrode member suitable for joining with an adhesive. The ground electrode 18c of the piezoelectric sensor 18 is joined and electrically connected to a measured member 7b with the non-electroconductive adhesive. By measuring a capacitance between the output electrode 18b of the piezoelectric sensor 18 and the measured member 7b, the electrical connection is checked.
