本考案は、ハーメチツク型容器の圧電振動子を
表面実装型圧電振動子にする改良に関する。[Detailed Description of the Invention] <Object of the Invention> [Industrial Application Field] The present invention relates to an improvement in converting a piezoelectric vibrator in a hermetic container into a surface-mounted piezoelectric vibrator.

ことも考えられるが工数がかかる。[Prior Art] Piezoelectric vibrators in hermetic containers with good airtightness are widely used. In order to make this hermetic type piezoelectric vibrator into a surface mount type which is currently in demand, an adapter was added to the main surface of the bottom surface on the lead terminal side of the hermetic type container, and a terminal body made by bending a metal plate was added to lead out the lead terminal. It has been proposed that a surface-mounted piezoelectric vibrator be added to the piezoelectric vibrator. However, the connection between the hermetic container and the adapter is simply by fixing the terminal body and the lead terminal, and if, for example, solder is used here, there is a risk that it will come off due to impact such as heating or tension. It is conceivable to use resin or the like to secure the hermetic container and the adapter to each other in order to protect them from impacts such as heating and tension, but this requires a lot of man-hours.

The hermetic container and the adapter are firmly attached.

固着される。[Operations and Examples] FIG. 1 is a perspective view showing the outer shape of the present invention.
FIG. 2 is a sectional view showing an embodiment of the present invention. An adapter 2 made of an insulating material such as resin is attached to the bottom of the terminal side of the hermetic container 1 sealed by resistance welding or cold welding. The adapter 2 has a cavity at the bottom for filling with resin. The lead terminal 3 led out from the hermetic container 1 is fixed with a fixing material 5 such as solder or conductive adhesive to a terminal body 4 made by bending a metal plate that fits into the cavity at the bottom of the adapter. FIG. 3 is a sectional view seen from the side. The terminal bodies are led out on both sides in the short side direction.
The adapter 2 is provided with a through hole 6 between the hermetic container and the cavity. When the resin 7 is poured into the bottom cavity, the resin 7 also flows into the through hole 6, and the hermetic container 1 and the adapter 2 are firmly fixed.

た。<Effects of the present invention> The through-hole of the adapter according to the present invention eliminates the peeling of the hermetic container and adapter due to heat and shock, and ensures reliable adhesion and high reliability. Because of this, conventional manufacturing methods can be used without using adhesives, and since the filling resin is also used, it has become possible to obtain inexpensive surface-mounted piezoelectric vibrators.
