A cold-seal package affording resistance to high temperatures, comprising a base and a cover provided with an annular flange and so designed as to be brought into contact with each other in such a manner as to permit cold-sealing and encapsulation of an element to be protected. The base comprises a cup and a metallic mounting-plate, connector-pins being rigidly fixed to the mounting-plate and insulated with respect to this latter. The package is a vacuum-tight case comprising at least two columns located within the cover and rigidly fixed to the mounting-plate in order to suspend the element to be protected, and a ground pin brazed to the cup.

Cold-seal package for withstanding high temperatures

A piezoelectric resonator including a base, two conducting posts which pass through the base and a piezoelectric plate. The plate includes a central active zone which is surrounded by a peripheral zone. The two zones are connected by at least two bridges which define slits which separate the central zone from the peripheral zone. Each face of the central zone is covered with an adherent electrode which extends over one of the bridges to a part of the peripheral zone. Each of the electrodes is connected to one of the conducting posts through a conductive metal ribbon. Each of the metal ribbons bear on the inner part of the peripheral zone so that the ribbon is disposed substantially as an extension of the corresponding posts.
