Description
PTC素子62の上下にフィン69を配置すると共に、フィン69に接して電極部材67、68を設けたヒータユニットが2つ積層された構造を有する。電極部材67は、2つのヒータユニットで共用されている。
図1は、本発明の実施形態に係る車載用ヒータ1の平面図である。
図3は図2おけるA−A線方向の拡大断面図を表す。
なお、他の発熱体ユニット3b、3cも、発熱体ユニット3aと同様に構成される。
キャップ6の端面には6個のスリットが形成され、それらスリットを介して、各発熱ユニット3a〜3cが一対ずつ備える電極部材22a、22bの各端子部27a〜27fの先端が、キャップ6の外側に突き出ている。
接続部材35は、端子部27aの先端を挟み込むように二つ折りにされて端子部27aの先端に取り付けられた折り曲げ片部35aと、この折り曲げ片部35bの上端部に一体に設けられた断面略C字状の筒部35bとからなる。
この発熱体ユニット21が、図3に表される上述した実施形態と異なるのは、電極部材22aと、放熱面12aの裏面との間の部分で、絶縁シート24の両端縁部24a、24bを重ね合わせている点である。
この発熱体ユニット31では、電極部材22aの外側にスペーサ29を重ねた上で、発熱素子20、電極部材22a、22b、スペーサ29を絶縁シート24で包んで、筒体12の中空部13に収容して、筒体12を押しつぶしている。
