Description
本発明の導電ゴム部品の使用方法は、前記の導電ゴム部品の使用方法であって、プリント配線板と携帯電話機の樹脂ボディ裏側の導電面とを電気的に導通するために使用することを特徴とする。
本発明の携帯電話機は、プリント配線板と携帯電話機の樹脂ボディ裏側の導電面とを電気的に導通するために前記の導電ゴム部品が実装されていることを特徴とする。
図1〜2に示す導電ゴム層と絶縁ゴム層とが交互に平行となるように積層された積層体の導電性ゴム材料は、電気絶縁性シリコーンゴムKE530U(製品名、信越化学工業社製)100重量部に対して、導電性フィラーとして平均粒径20μmの銀コートガラス粉S3000(製品名、東芝バロティニ社製)、300重量部を混合し、さらに加硫剤として2・5−ジメチル−2・5−ジ(t−ブチルパーオキシ)ヘキサン、50重量%含有の加硫剤RC−4(製品名・東レ・ダウコーニング・シリコーン株式会社製)5重量部を均質に混錬りした。本配合物をASTMD991法で体積固有抵抗を測定したところ0.07Ω・cmであった。次いで、圧延ロールで圧延して厚さ5mmの圧延シートを作成した。

(1)圧縮永久歪性の良い電気絶縁性ゴム層で導電性ゴム層を挟んだ構造であるため、高い圧縮永久歪性を持っている。
(2)導電性ゴム層を電気絶縁性ゴム層間に挟むことで、圧縮永久歪性が劣化しにくくなり、圧縮接合時の反発が継続的に維持されるようになる。その結果、製品の反発弾性が長期間に渡って維持されるので、経時的な接触抵抗の上昇が少なく、安定的な電気的接続を得ることが可能となる。
(3)ゴム部品として良低荷重性が確認できた。
(4)製品片面に半田付け可能な金属皮膜が一体成形されるため、プリント配線板上にリフロー可能な金属皮膜一体の導電ゴム部品にできる。
