ABSTRACT:
A piezoelectric resonator element having supporting lead members projecting in opposite directions therefrom is positioned in a tubular dielectric case having tubular metal cap members affixed at opposite ends thereof and extruding beyond the ends of the case. Inner end portions of the cap members are hermetically sealed to the case. Intermediate portions of the cap members beyond the ends of the case are compressed onto end portions of the lead members to secure the resonator element in position in the case and to make electrical contact between the lead members and the metal cap members. End portions of the cap members beyond the ends of the lead members are compressed to seal the case, the sealing being effected in a vacuum so as to evacuate the interior of the case. In order further to seal the case, the outer ends of the cap members may be welded or soldered.
