【発明の詳細な説明】
本発明は、アコースティックエミッション検出用変換器
における圧電振動子と保護板との接着方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of bonding a piezoelectric vibrator and a protection plate in a transducer for acoustic emission detection.
アコースティックエミッション検出用変換器（以下単に
ＡＥ検出用変換器と云う）は、ＡＥを検出すべき被験体
に取付けて使用する。An acoustic emission detection converter (hereinafter simply referred to as an AE detection converter) is used by being attached to a subject whose AE is to be detected.
第１図に示す如く、ＡＥ検出用変換器１における圧電振
動子２の下面には、圧電振動子２の下面全体に付着しで
ある例えば銀電極２ａを保護するための保護板３が例え
ばエポキシ樹脂接着剤４により接着されている。As shown in FIG. 1, on the lower surface of the piezoelectric vibrator 2 in the AE detection transducer 1, there is a protective plate 3 made of, for example, epoxy, which is attached to the entire lower surface of the piezoelectric vibrator 2 and protects the silver electrode 2a. It is bonded with a resin adhesive 4.
前記銀電極２ａの引張り剪断強度は約２０にν瀝である
だめ、保護板３を介する衝撃に弱く、銀電極２ａが圧電
振動子２から剥離してしまい、従って保護板３から圧電
振動子２ａが脱落してしまう欠点があった。Since the tensile shear strength of the silver electrode 2a is about 20, it is vulnerable to impact through the protection plate 3, and the silver electrode 2a peels off from the piezoelectric vibrator 2. It had the disadvantage that it would fall off.
本発明は、かくの如き欠点を解決すべくしたものであっ

２全体にエポキシ樹脂接着剤を塗布し、しかる後、圧電
振動子２の下面に保護板３を接着するのである。As shown in FIG. 1, when the protection plate 3 is bonded to the bottom surface of the piezoelectric vibrator 2 via the epoxy resin adhesive 4, the bottom surface of the piezoelectric vibrator 2 is bonded as shown in FIGS. A part of the surface of the silver electrode 23 that is attached to the entire piezoelectric vibrator 2 is removed, an epoxy resin adhesive is applied to the entire piezoelectric vibrator 2, and then a protective plate 3 is bonded to the bottom surface of the piezoelectric vibrator 2. be.

張り剪断強度が数１ｏｏＫｙ／ｆｆｌであることから、
保護板３と圧電振動子２とを強固に接着でき、従って強
い衝撃力が保護板３に加わっても、銀電極２ａが圧電振
動子２の下面から剥離するようなことが防止される。By doing this, the protection plate 3 and the piezoelectric vibrator 2 are directly bonded, and since the tensile shear strength of the epoxy resin adhesive is several 1ooKy/ffl,
The protective plate 3 and the piezoelectric vibrator 2 can be firmly bonded together, so that even if a strong impact force is applied to the protective plate 3, the silver electrode 2a is prevented from peeling off from the lower surface of the piezoelectric vibrator 2.
