PIEZOELECTRIC RESONATOR

摘要

A piezoelectric resonator comprising a base through which pass two conducting posts insulated therefrom and a piezoelectric plate comprising a central active zone surrounded by a peripheral zone connected to said central zone by at least two bridges defining slits separating said central zone from said peripheral ring, each face of said central zone being covered with an adherent electrode extending through at least one of the bridges over a part of said peripheral ring, each electrode of the plate being connected to one of the conducting posts through conducting fixing means. In accordance with the invention, said conducting fixing means are formed by a metal ribbon bearing on the inner part of said peripheral zone so that said ribbon is disposed substantially in the extension of the corresponding post.
