【考案の詳細な説明】
本考案は水晶振動子等の結晶あるいはセラミック等の圧
電振動子の支持構造に関するものである。[Detailed Description of the Invention] The present invention relates to a support structure for a piezoelectric oscillator made of a crystal such as a crystal oscillator or a ceramic oscillator.
水晶振動子の従来の支持構造は一般に、第1図に示すよ
うに、振動子の相対する金属電極膜2,3に先端を二重
に巻いた金属弾性支持線4で挟持し半田等で接着し、基
台5にガラス等で絶縁して外部端子6を引き出す構造に
なっている。As shown in Fig. 1, the conventional support structure for a crystal resonator is generally such that the opposite metal electrode films 2 and 3 of the resonator are held between two elastic metal support wires 4 whose ends are double-wound and bonded with solder or the like. The structure is such that the base 5 is insulated with glass or the like and external terminals 6 are drawn out.
しかしながらこのようにして構成された圧電振動子は、
前記した金属弾性支持線4のバネ圧が強ければ、振動子
へ働く応力が大きくQ値の低下となり、バネ圧が弱けれ
ば、外部からの衝撃に弱く、また金属電極膜2と金属弾
性支持線4との導電性接着は粘性減衰によるQ値の低下
が大きく、特に近年注目されている腕時計用など小型形
状のものでは応用することが難かしい。However, the piezoelectric vibrator configured in this way is
If the spring pressure of the metal elastic support wire 4 described above is strong, the stress acting on the vibrator will be large and the Q value will be reduced. If the spring pressure is weak, it will be weak against external shocks, and the metal electrode film 2 and the metal elastic support wire Conductive adhesion with No. 4 causes a large drop in Q value due to viscous attenuation, making it difficult to apply to small-sized devices such as wristwatches, which have been attracting attention in recent years.
本考案は腕時計用など特に小型形状の圧電振動子の支持
構造で前記した従来技術の欠点を鑑みこれを克服したも
のである。The present invention is an attempt to overcome the drawbacks of the prior art described above with respect to a support structure for a piezoelectric vibrator of a particularly small size such as for a wristwatch.

ことも出来る。In addition to the method described above, welding of a metal ribbon to the electrode metal film 2 can also be used to connect the electrode metal film 2 and the external lead wire 8.
圧電振動子体としての組立ては、第3図で基台9に装着
しである絶縁性部材3,5の凹部に圧電振動子を固定し
、前記電極引き出しの配線をする。To assemble the piezoelectric vibrator body, as shown in FIG. 3, the piezoelectric vibrator is fixed in the recesses of the insulating members 3 and 5 mounted on the base 9, and the wiring for the electrode extraction is performed.

このように本考案は柔軟性のある絶縁性部材で振動子を
圧接支持するものであるため、次のような効果を有する
。As described above, since the present invention supports the vibrator in pressure contact with a flexible insulating member, it has the following effects.
すなわち、振動子が絶縁性部材により位置決めされるた
め、特に、落下衝撃時に振動子の位置がほとんどずれる
ことがなく、また、絶縁性部材には柔軟性があるから振
動子に急激な力が加わることがなく、破壊されにくいと
ともに、周波数変化が起らない。In other words, since the vibrator is positioned by an insulating member, the position of the vibrator will hardly shift especially in the event of a fall impact, and since the insulating member is flexible, a sudden force will be applied to the vibrator. It is not easily destroyed and does not cause frequency changes.
これに対し、剛体支持をすると、振動子の振動が剛体支
持材を介してケースに直接伝わり、振動エネルギーの散
逸が起る。On the other hand, when rigid support is used, the vibration of the vibrator is directly transmitted to the case via the rigid support material, causing dissipation of vibration energy.
その結果、振動子の等価抵抗の増大、すなわちQ値の低
下が生しる。As a result, the equivalent resistance of the vibrator increases, that is, the Q value decreases.
本考案は柔軟性のある支持材を用いているため、振動エ
ネルギーの散逸はほとんど起らず、高いQ値を保つこと
ができる。Since the present invention uses a flexible support material, almost no vibration energy is dissipated, and a high Q value can be maintained.
