Description
【考案の詳細な説明】
本考案は圧電素子ユニットの高圧リード線固定構造に改
良を加え、製作を容易にしコストの低減を目的とするも
のである。[Detailed Description of the Invention] The present invention aims to improve the high-voltage lead wire fixing structure of a piezoelectric element unit to facilitate manufacturing and reduce costs.
従来この種の圧電素子ユニットで高圧リード線固定は、
第１図に示すように圧電素子２０間に介在した中間端子
３に高圧リード線６を差し込み、エホキシ系接着剤７等
で接着固定をしていた。Conventionally, high voltage lead wires were fixed with this type of piezoelectric element unit.
As shown in FIG. 1, a high-voltage lead wire 6 was inserted into an intermediate terminal 3 interposed between piezoelectric elements 20, and adhesively fixed with an epoxy adhesive 7 or the like.
この構造だと接着剤の配合、塗布、乾燥等の工数がかか
り、また接着剤の可使時間等により使用不能等の接着剤
の廃棄等でコスト高の要因となっていた。This structure requires many man-hours to mix, apply, and dry the adhesive, and also causes high costs due to the disposal of adhesive that cannot be used due to the pot life of the adhesive.
１はケース、４は当て金、５は当て板である。本考案は
上記従来の欠点を除去し、構造が簡単で製造の簡略化が
計れた圧電素子ユニットを提供しようとするものである
。1 is a case, 4 is a pad, and 5 is a pad. The present invention aims to eliminate the above-mentioned drawbacks of the conventional piezoelectric element unit, and to provide a piezoelectric element unit that is simple in structure and easy to manufacture.
以下に本考案の一実施例を第２図および第３図と共に説
明する。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.
第２図、第３図において、１１は圧電素子収納用のケー
スで、このケース１１の中央部には、高圧リード線挿入
用の開口部を有する凸状のリード線引出し部１１が設け
られている。In FIGS. 2 and 3, 11 is a case for storing a piezoelectric element, and a convex lead wire pull-out portion 11 having an opening for inserting a high voltage lead wire is provided in the center of the case 11. There is.
１２は圧電素子、１３は圧電素子１２の間に介在する中
間端子、１４は当て金、１５は当て板、１６は高圧リー
ド線、１７は上記リード線引出し部１１′の壁面に設け
られた一対の透孔、１８はその開口部先端を上記リード
線引出し部１１′の透孔１７に係合する凹状の絶縁性係
合体である。12 is a piezoelectric element, 13 is an intermediate terminal interposed between the piezoelectric elements 12, 14 is a stopper, 15 is a backing plate, 16 is a high voltage lead wire, and 17 is a pair provided on the wall surface of the lead wire extraction portion 11'. The through hole 18 is a concave insulating engaging body whose opening tip engages with the through hole 17 of the lead wire pull-out portion 11'.
ここで、絶縁性係合体１８の開口部先端の内寸は高圧リ
ード線１６の外径より小さく、高圧リード線１６をケー
ス１１と絶縁性係合体１８で固定している。Here, the inner dimension of the opening tip of the insulating engaging body 18 is smaller than the outer diameter of the high voltage lead wire 16, and the high voltage lead wire 16 is fixed between the case 11 and the insulating engaging body 18.
本考案の固定構造によれば、容易に作成できる凹状の絶
縁性係合体により高圧リード線を簡単に固定できる。According to the fixing structure of the present invention, the high voltage lead wire can be easily fixed using the concave insulating engaging body that can be easily produced.
また、接着剤の配合、塗布、乾燥等の工数がかからなく
、接着剤が必要でなくなり使い残りを廃棄する等のコス
ト高の要因をなくすことができる。In addition, there is no need for man-hours such as mixing, applying, and drying the adhesive, and the need for adhesive eliminates the need to dispose of unused adhesives, which increases costs.
このように簡単な構造で製造が容易になったものである
。This simple structure makes manufacturing easy.
