Abstract
Description
図1は本開示の実施の形態1における電子部品モジュール7の構成を示す外観側面図であり、図2は本開示の実施の形態1における電子部品モジュール7の構成を示す外観斜視図である。
図3は実施の形態2における電子部品モジュール7の構成を示す外観側面図である。なお、上述した実施の形態1と同様の構成については同一の符号を付して説明を省略する場合がある。図1に示す実施の形態1では、第1導体部13の端部13bから第1接続導体部14がZ方向に延伸している。一方、図3に示す実施の形態2では、端部13aと端部13bの間の領域から第1接続導体部14がZ方向に延伸している。第1接続導体部14と第1導体部13の接触部分のうち、第1接続導体部14のX方向とは反対方向の端を位置B(図3参照)とする。第1導体部13の端部13bは、位置BからX方向とは反対の方向に延伸している。本実施の形態では、第1導体部13がX方向とは反対の方向に拡張されるように延伸しているので、拡張した第1導体部13の第1平面P1に沿った面の面積が電子部品モジュール7の放熱性向上に寄与する。
図4は本実施の形態3における電子部品モジュール7の構成を示す外観側面図である。図3に示す実施の形態3の電子部品モジュール7が図1に示す実施の形態1の電子部品モジュール7と異なる点は、第1導体部13(第1バスバ10)と第2導体部17(第2バズバ11)と、第3導体部20(第3バスバ12)とに熱的に結合された放熱体23が設けられている点である。この構成により、ヒューズ8またはリレー9で発生した熱が、第1導体部13、第2導体部17バ、または第3導体部20から効率よく電子部品モジュール7の外部へと放出される。先に述べたように、ヒューズ8の特にヒューズ本体部8Aは、第1バスバ10における放熱の機能を有する第1導体部13および第2バスバ11における放熱の機能を有する第2導体部17の下方(Z方向)に配置されている。この構成により、電子部品モジュール7全体を大きくすることなく、ヒューズ本体部8Aの上方(Z方向の反対方向)のスペースに、第1導体部13および第2導体部17の少なくとも一方を延伸させることができる。よって、第1導体部13および第2導体部17の少なくとも一方の面積を大きくすることが可能になり、第1導体部13または第2導体部17の少なくとも一方の放熱体23への伝熱効率が向上する。本実施の形態では、電子部品モジュール7の放熱性を向上させることができる。
図5は実施の形態4における電子部品モジュール7の構成を示す外観斜視図である。なお、上述した実施の形態1と同様の構成については同一の符号を付して説明を省略する場合がある。図5に示す実施の形態4では、図1に示す電子部品モジュール7が、第1バスバ10と第2バスバ11と第3バスバ12とを固定する樹脂フレーム25をさらに備えている。なお、図5ではリレー9を図示していないが、実際にはリレー9は他の実施の形態と同様に配置される。また、本実施の形態においても、図4に示す実施の形態3と同様に、放熱体23(図4参照)を配置してもよい。
図6は実施の形態5における電子部品モジュール7の構成を示す外観斜視図である。電子部品モジュール7は樹脂フレーム25を保持し、リレー本体部9Aが固定される筐体26を更に備えている。なお、図6では筐体26の形状を分かりやすくするため、樹脂フレーム25の開示は省略している。図6に示す構成では、放熱体23、第1バスバ10、第2バスバ11、第3バスバ12、リレー9の位置関係がさらに安定する。結果として、第1導体部13、第2導体部17、第3導体部20からの放熱特性はさらに向上する。
本開示の電子部品モジュール7は、ヒューズ本体部8Aと、第1ヒューズ端子部8Bと、第2ヒューズ端子部8Cと、を有するヒューズ8と、リレー本体部9Aと、第1リレー端子部9Bと、第2リレー端子部9Cと、を有するリレー9と、X方向およびX方向と直交するY方向に沿って延伸する板状の第1導体部13と、第1導体部13からX方向およびY方向に交差するZ方向に向かって延伸し、X方向およびZ方向に沿って延伸する板状部14aを有する第1接続導体部14と、X方向およびY方向に沿って延伸する板状の第2導体部17と、第2導体部17からZ方向に向かって延伸し、X方向およびZ方向に沿って延伸する板状部18aを有する第2接続導体部18と、X方向およびY方向に沿って延伸する板状の第3導体部20と、を備える。
