【考案の詳細な説明】
従来より、圧電振動子の支持方法として、第１図に示す
ような、溝や孔を設けた板バネを有する支持体が用いら
れて来た。[Detailed Description of the Invention] Conventionally, as a method of supporting a piezoelectric vibrator, a support body having a plate spring provided with grooves and holes, as shown in FIG. 1, has been used.
この方法は、クリップピンを用いる方法に比べて作業性
の点で非常に有利なものであるが、板バネであるが故に
、その板面に垂直な方向（図中■■）の振動・衝撃には
極めて強い反面、板面に平向な方向（図中←→）の運動
に対しては自由度が極めて小さく、この方向に力が加わ
った場合、素板１が容易に破損してしまう危険があった
。This method is very advantageous in terms of workability compared to the method using clip pins, but since it is a leaf spring, vibration and impact in the direction perpendicular to the plate surface (■■ in the figure) Although it is extremely strong, the degree of freedom for movement in the direction parallel to the plate surface (←→ in the figure) is extremely small, and if force is applied in this direction, the blank plate 1 will be easily damaged. There was danger.
本考案はこの点を改善するためになされたもので、板バ
ネの板面内に屈曲部を設けた支持体を用いることにより
、該板面に平行な力に対しても十分な耐性を持たせるこ
とに成功したものである。The present invention was made to improve this point, and by using a support with a bent part in the plate surface of the leaf spring, it has sufficient resistance even to forces parallel to the plate surface. This is something that we succeeded in doing.
第２図は、本考案の一実施例である圧電振動子の支持体
を示すが、図中、支持体３は、平板状バネ材によって、
溝を有する支持部３□および外部引出部３３共に、一体
形成され、基台２に植設されているが、該支持部３□と
基台２との間には、該平板面内で屈曲する屈曲部３□が
設けられ、そのために同図の矢印で示される方向に対し
ても良好な耐振動・衝撃性を備える。FIG. 2 shows a support body for a piezoelectric vibrator which is an embodiment of the present invention.
Both the support part 3□ having a groove and the external drawer part 33 are integrally formed and planted on the base 2, but there is a bending part between the support part 3□ and the base 2 within the plane of the flat plate. A bent portion 3□ is provided to provide good vibration and shock resistance even in the direction indicated by the arrow in the figure.
この支持体の屈曲部としては種々の態様が考えられるが
、第３図にその一例を示す。Various embodiments can be considered for the bent portion of this support, one example of which is shown in FIG.
かくして本考案によれば、素板面に平行な方向にも、垂
直な方向にも良好な耐振動・衝撃性を有し、かつ作業性
の極めて高い、圧電振動子が得られる。Thus, according to the present invention, it is possible to obtain a piezoelectric vibrator that has good vibration and shock resistance both in directions parallel to and perpendicular to the surface of the base plate, and has extremely high workability.
さらに、この支持体は弾性材の平板からエツチングやプ
レス加工により形成されるが、その際、外部引出線をも
一体形成しうるから、この点においても、第１図の例の
ように板バネ４を別個に作製して外部引出線５に溶接し
ていた構造に比べ、製造工程が簡略化される利点を有す
る。Furthermore, this support is formed from a flat plate of elastic material by etching or pressing, and at that time, the external leader line can also be integrally formed. This has the advantage that the manufacturing process is simplified compared to a structure in which the wire 4 is separately manufactured and welded to the external leader wire 5.
以上、単一電極対の振動子を例にとって説明したが、２
電極対以上の場合も全く同様で、むしろ電極数が多くな
って板バネの数が増加する程、素板方向の運動に対する
自由度は減少して素板破損の危険度は高まるから、本考
案を用いる利益は増大するともいえる。The above explanation was given using a single electrode pair vibrator as an example.
The same is true for electrode pairs or more; in fact, as the number of electrodes increases and the number of leaf springs increases, the degree of freedom for movement in the direction of the blank plate decreases, and the risk of breaking the blank plate increases. It can also be said that the benefits of using .
第４図に２電極対の場合を示すが、この場合、中央の短
い支持体には例えば第５図に示すような形状のものが用
いられる。FIG. 4 shows the case of two electrode pairs; in this case, the central short support has a shape as shown in FIG. 5, for example.
３電極対以上の振動子についても、適宜、形状・寸法を
変えた支持体を組合せて用いる。For vibrators having three or more electrode pairs, supports with different shapes and dimensions are used in combination as appropriate.
