ABSTRACT:
A piezoelectric resonator of small dimensions comprises a vibrating element mounted in a tight sealed housing (1) of elongated shape. The housing comprises a base (10) onto which a metal cap (9) is fixed, and coupling conductors (11) which pass through the base to connect the vibrating element to the exterior of the housing. The metal cap is formed by a part in the shape of a rectangular parallepiped which has, in its lengthwise direction, a cylindrical axial blind hole. This shape allows the cap to have a much better mechanical resistance than that of a conventional cylindrical cap and allows the resonator to be easily mounted, in an automatic manner, onto a support.
