Description
図1は、実施の形態1に係る半導体装置を示す断面図である。図2は、実施の形態1に係るインサートケースを示す斜視図である。インサートケース1は、複数の端子2と、複数の端子2の中央部2aを覆う樹脂3とを有する。複数の端子2は互いに平行に並んでいる。端子2はL字状に折れ曲がっている。端子2の一方の端部2bがインサートケース1の上側に突出している。端子2の他方の端部2cがインサートケース1の内側に突出している。
図11は、実施の形態2に係る端子とインサートケースの内側面を拡大した側面図である。図12は、実施の形態2に係るインサートケースの内側面を拡大した斜視図である。端子2の中央部2aに切り欠き2eが設けられている。切り欠き2eに沿うように穴15が設けられている。インサート成形時にスライドコア18を切り欠き2eに挿入する。これにより強固に端子2を固定できるため、樹脂流動による端子2の変形を抑制する効果を高めることができる。その他の構成及び効果は実施の形態1と同様である。
図13は、実施の形態3に係る端子を示す斜視図である。図14は、実施の形態3に係るインサートケースの一部を拡大した斜視図である。端子2の切り欠き2eが設けられた部分がインサートケース1の樹脂3の外側まで及んでいる。切り欠き2eに沿うように設けられた穴15がインサートケース1の外側の溝を構成する。
