Abstract
Description
PTC組成物により形成され、少なくとも1つの貫通開口部を有するPTC層状要素、
PTC層状要素の各主表面上に位置する導電性金属薄層、および
該貫通開口部の少なくとも1つを規定する側面上に位置し、各主表面上の導電性金属薄層を電気的に接続するヒューズ層
を有して成る、保護素子を提供する。
図1および図2に示す本発明の保護素子を製造した。従って、ヒューズ層40のみを有し、ヒューズ層32を有さない保護素子10を製造した。但し、周辺貫通開口部14は、周状に等間隔で8つ形成した。
貫通孔(周辺貫通開口部14に対応)を形成した後のメッキ処理を、無電解法によるNiメッキ処理、ついで、電解法によるSnメッキ処理により行い、厚さ約1.5μmのニッケル層(第1金属層41に対応)および厚さ約6.5μmであるSn層(第2金属層42に対応)を得たこと以外は、実施例1と同様にして、本発明の保護素子を得た。
実施例1および2の保護素子の、一方の導電性金属薄層22から他方の導電性金属薄層24に、下記表1に示す電流(60Vdc設定)をそれぞれ流した。結果、10分間ヒューズ層がブローすることなく電流を流し続けることができた最大電流値を定格容量と定義した。その結果、実施例1の保護素子の定格容量は25A、実施例2の保護素子の定格容量は22.5Aであった。
実施例1および2の保護素子の、一方の導電性金属薄層22から他方の導電性金属薄層24に、試験例1にて定義した定格容量の4倍の電流を各実施例のサンプルに印加(60Vdc設定)し、電流遮断時間を測定した。その結果、保護素子の電流遮断時間は、どちらも1秒以内であった。
試験例2で過剰電流を遮断した後、保護素子への通電を止め、10分間静置した。ついで、再び、一方の導電性金属薄層22から他方の導電性金属薄層24に、100A(60Vdc)の電流を6秒間印加しPTC素子が動作(トリップ)するかのトリップ特性を確認した。6秒間電流印加後、54秒間を電流(電圧)無通電とし、これを1サイクルとしてそれぞれのサンプルに対して10サイクルを行った。結果、どちらも発火・発煙なくPTC特性を有していることが確認された。
