本発明は圧電発振片と発振回路とが同一パッケージ内に

8 is fixed by soldering etc. in the same manner as the elements 52,
A piezoelectric oscillation piece (in this example, a crystal oscillation piece) 55 is fixed onto the support pin 58 with a conductive adhesive 54 .

提供することにある。However, according to the conventional configuration described above, the stem circuit board and support bin have almost no elasticity, and the conductive adhesive that joins them also has almost no elasticity, so Since shocks and vibrations are directly transmitted to the piezoelectric oscillating piece, cracking of the piezoelectric oscillating piece is likely to occur, and there is a problem that the impact and explosion resistance is poor. Its purpose is to provide a piezoelectric oscillator with excellent shock resistance.

1, Adhesion Th1l) 7'! i1'' and make this flexible conductor into a semi-hardened state without completely curing the adhesive.Furthermore, on top of the flexible guide adhesive 7 which is in the semi-hardened state, another layer of the same flexible adhesive as above is applied. Apply a magnetically conductive adhesive 4'!r7 to establish electrical continuity. Place the entire crystal oscillator piece 5 on top of this and allow it to harden completely. As shown in Figure 2, between the crystal oscillator piece 5 and the circuit board 3, A flexible conductive adhesive 7 that hardens to become a rubber-like elastic material is provided.
It is constructed. Here, the semi-hardened flexible 41
1 The reason for providing the adhesive 1i1 is to reliably create a rubber-like elastic body without impairing conductivity.If you place the crystal oscillator directly on a low-viscosity adhesive, the adhesive This is because the crystal oscillation piece spreads laterally, the gap between the crystal oscillation piece and the circuit board becomes extremely small, and the elasticity 1i1 is almost completely lost, making it impossible to exhibit a sufficient effect.

The effect is the same even if the conductive material 24 is fixed to the outer periphery of the agent 27 to establish conduction. Also, as shown in FIG. 4, a cylindrical support bottle 7 made of gold 14 or a plate-like support (not shown) etc., it is convenient to use an elastic material such as a flexible conductive adhesive between the ceramic substrate 11 and the support bin 17, or between the support bin 17 and the crystal oscillation piece 15. However, it has the same effect. Also, as shown in Fig. 5, the support bin 67
Even if the ice crystal oscillation piece 65 is inserted into the slit, the same effect can be obtained if the gap is filled and fixed with the elastic material of the flexible 4-electromagnetic agent 454.
