本発明は水晶振動子の支゛持構造に関し、詳しくは、リ
ード端子の構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a support structure for a crystal resonator, and more particularly to a lead terminal structure.
本発明の水晶振動子の支持構造に関し、従来例を第１図
（Ａ）の正面断面図、同図（Ｂ）の側面断面図で示す。Regarding the support structure for the crystal resonator of the present invention, a conventional example is shown in a front sectional view in FIG. 1(A) and a side sectional view in FIG. 1(B).
同図において、１は水晶発振片、２は該水晶発振片１０
基部と固着する折返し形状を有するリード端子で、二つ
の異なる振動モードの結合により発振する結合音叉型水
晶振動子（以下、振動子）を示すものである。ところで
、最近の薄型。In the figure, 1 is a crystal oscillation piece, 2 is the crystal oscillation piece 10
This is a lead terminal with a folded shape that is fixed to the base, and represents a coupled tuning fork type crystal resonator (hereinafter referred to as a resonator) that oscillates by combining two different vibration modes. By the way, the latest thin models.
小型化機器の要求に対応し本例の振動子も小型化の対策

と捩り振動の基本波振動を用いた結合形振動子の場合、
この傾向が顕著であった。In response to the demand for miniaturized equipment, measures have been taken to miniaturize the vibrator in this example, but as shown in the figure, in the case of a lead terminal with a folded shape, the advantage of preventing vibration leakage has been achieved, It is necessary to realize further miniaturization. Therefore, the most common countermeasure is to design the width, thickness, etc. of the lead terminals to dimensions suitable for miniaturization. When the diameter of the cylindrical case 3 is downsized to 1.5fi, the width of the lead terminal is as small as Q, 1-, so the smaller the size, the lower the rigidity of the lead terminal, and the impact resistance of the resonator. The problem was that it became unstable. In particular, in the case of a coupled vibrator using two different vibrations in this example, namely the first harmonic of bending vibration and the fundamental wave vibration of torsional vibration,
This tendency was remarkable.
本発明は以上の問題を解決するもので、その目的とする
ところは、小型で振動洩れの少ない水晶振動子の支持構

支持構造の、骸リード端子が該リード端子より高い剛性
を有する金属材料で被覆されていることを特徴とする。In the support structure for a crystal resonator of the present invention, in the support structure for a crystal resonator formed by fixing the base of a crystal oscillation piece and the tip of a lead terminal, the skeleton lead terminal is made of a metal having higher rigidity than the lead terminal. It is characterized by being covered with a material.
以下、本発明について実施例に基づき説明する。 Hereinafter, the present invention will be explained based on examples.

設けるのが一般的となる。In the figure, the outer diameter of the cylindrical case 6 is 1.5. The width of the lead terminal 5 formed by photo-etching or press processing is limited to (lLlgIrIR) at the maximum. Therefore, it is common that the thickness of the lead terminal 5 is also provided at α1-.

る水晶発振片先端の撓みはほぼ防止することができる。As described above, supporting the crystal oscillator piece using thin and thin lead terminals for the purpose of miniaturization poses problems as described above. In order to solve this problem, the present invention uses Kovar (Fe12, Ni29%, 0o
Nickel (IJ4), which is more rigid than Kovar, and gold-tin (Au-8n) are used for the lead terminal 5 formed of Kovar.
), chromium (Or), etc., was coated with a metal material 7 using a plating method. If this lead terminal is used, the shock resistance of the vibrator is greatly improved, and it is possible to almost prevent the tip of the crystal oscillation piece from bending under a certain shock compared to the conventional case.

range of 5-20M, according to experiments 10-12M
Good results have been obtained for both m. Further, for miniaturization, the outer diameter of the cylindrical case can be reduced by 3 degrees.
