ABSTRACT:
In a piezo-resonator in which the resonator cavity is coated with a resinous insulator, a lip which defines a ridge for the mounting of the terminal strips to the resonator is fused to the outer surface of the strips. The seal produced thereby prevents resin from invading the resonator cavity during the resin coating process.
