Abstract
Description
最初に本開示の実施態様を列挙して説明する。また、以下に記載する実施形態の少なくとも一部を任意に組み合わせてもよい。
本発明をその実施形態を示す図面に基づいて具体的に説明する。本開示の実施形態に係る回路構造体及び電気接続箱を、以下に図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されるものではなく、特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。
本実施形態に係る電気接続箱100は略箱体の形状をなしており、制御回路基板9と、制御回路基板9を収容する回路構造体10と、回路構造体10を覆う蓋80と、回路構造体10を挟んで蓋80と反対側に設けられ、回路構造体10が発する熱を放熱するヒートシンク90とを備える。ヒートシンク90は、ネジ70が回路構造体10の四隅に形成された貫通孔60に挿入されてヒートシンク90の四隅に形成された螺子穴91と螺合することによって回路構造体10に取り付けられる。
本実施形態に係る回路構造体10はこれに限るものでなく、接続部31〜37及び第1バスバ3aを別々に設けて第1通電体3をなしても良い。
即ち、半導体素子71〜77は夫々導電部81〜87によって各接続端子4に接続される。例えば、絶縁部6は絶縁基板であり、導電部81〜87は絶縁部6の上面68にプリントされたパターンであっても良い。
詳しくは、各溝部が、第2通電体2に固定された各半導体素子71〜77のゲート端子に整合する位置から夫々対応する接続端子4まで凹設され、各溝部内に導電材、例えば銅ナノ粒子インクを塗布しても良い。
接続端子4は制御回路基板9に接続されており、制御回路基板9が送信する、半導体素子71〜77を制御する制御信号を、導電部81〜87を介して各半導体素子71〜77のゲート端子に送る。これによって、半導体素子71〜77が制御され、第1通電体3から第2通電体2へ、又は第2通電体2から第1通電体3への通電が制御される。
例えば、半導体素子71においては、ドレイン端子731が第2バスバ2aの前側の辺縁部にハンダ付けされている。これによって、半導体素子71が第2バスバ2aに接続されると共に、第2バスバ2aに固定される。
更に、導電部8は絶縁部6に設けられており、導電部8をパターン化することによって、多数の配線を集約して設けることができる。
更に、各接続部31〜37は、左右方向において、櫛歯状部600の欠落部601〜607の縁との間に第2間隔38が形成されており、第2通電体2の第2バスバ2aとの間に間隔50が形成されている。従って、接続部31〜37の前記一端部が左右方向に変形することが可能である。
導電部8の端部にははんだ実装用パッドが備わり、接続部31〜37の端面311〜317の近傍に並列される。なお、絶縁部6には、あらかじめ接続端子4をはんだ付けしておく。
これによって、半導体素子71〜77のドレイン端子が第2通電体2と接合され、半導体素子71〜77のソース端子が第1通電体3の接続部31〜37の前記一端に接合される。また、接続部31〜37のゲート端子が絶縁部6の導電部8と接合される。
