Abstract
PURPOSE:To facilitate fabrication of a pezoelectric element unit, by providing inside surface of an insulating semi-cylindrical body with protrudent coils to contain pressure-attached element and impact-receiving metal, etc., and then, by joining it with the other semi-cylindrical body in butt-on manner. CONSTITUTION:An insulating case 6 is formed in such a manner that it is joined at its circumferential end section and that two semi-cylindrical bodies which are free-to-turn centering on the joined section are butt-on welded to each other. Inside surfaces of the semi-cylindrical bodies 6a and 6b are provided with protrudent coils 6c to be pressure-attached onto outside surface of piezoelectric elements 1 and 1', center section of the semi-cylindrical body 6b is provided with an intermediate terminal 2 take-out cylinder 6d, and its axial end section is provided with a step section 6e for engagement between an impact-receiving metallic object 4 and a receiving body 5, and then, force to press the piezoelectric elements 1 and 1' is applied to the metallic object 4 and the receiving body 5 by the step section 6e. As it is possible, in this mechanism, to divide outside surface of the piezoelectric elements into many steps by the protrudent coils 6e and to prevent thereby internal discharge, necessity of impregnation of insulating resin becomes eliminated and therefore fabrication becomes easier.
