Quartz oscillator

Abstract

Abstract PURPOSE:To facilitate an automatic assembly and to decrease the number of component parts, by adhering the driving electrode of a quartz disphragm in a body to the through-hole of a printed circuit board opposite to each other with a conductive adhesive. CONSTITUTION:The driving electrodes 3a and 3b of a quartz plate 2 are connected to conductive adhesives 4a and 4b by copper foil electrodes 11a and 11b to be led outside by lead wires 8a and 8b through solders 12a and 12b respectively. Thus a small thickness of the plate 2 can be reinforced by a printed circuit board 1. Then a quartz oscillator can be constituted by conforming the electrodes 11a and 11b of the board 1 with the ends of the electrodes 3a and 3b of the plate 2 although the plate 2 has a limitation for its outer diameter.
