Description
また、本発明では、ケース(1)が底面(1a)と側壁面(1b)を有した構成とされ、基板(2)がケース(1)における底面(1a)に固定され、さらに、ケース(1)に基板(2)の上方に配置される上面部(7b)を有したベース(7)が固定されて、該ベース(7)に電気回路素子(8)が備えられるようになっている場合において、上層ゲル(3a)がベース(7)の少なくとも一部を覆うように配置されるようにすることを特徴としている。
このように構成された電気回路装置では、ベース(7)が底面(1a)から浮いた状態となり、振動し易い構造となる。ベース(7)の少なくとも一部が上層ゲル(3a)で覆われるような構造とすれば、硬い上層ゲル(3a)にてベース(7)の振動を抑えることができるため、ベース(7)の振動に起因するゲルの軟化を防止することも可能となる。
本発明の第1実施形態について説明する。図1は、本発明の第1実施形態が適用された電気回路装置の断面図である。以下、この図を参照して本実施形態の電気回路装置について説明する。
本発明の第2実施形態について説明する。本実施形態の電気回路装置は、第1実施形態に対して電気回路素子を搭載した保持用の樹脂ベースを追加したものであり、その他に関しては第1実施形態と同様であるため、異なる部分についてのみ説明する。
上記各実施形態では、電気回路基板2やそれに搭載される電気回路素子2a〜2cの一例を挙げたが、これらは単なる一例であり、他の構造であっても構わない。勿論、電気回路装置を構成している各部の材質などは一例であり、他の材質であっても構わない。
