Abstract
Description
以下、実施の形態1に係る回路接続装置2及び回転電機装置100について、図面を参照して説明する。
図1は、回転電機装置100の概略断面図である。回転電機装置100は、多相巻線型の回転電機1と、回転電機1を制御する回路接続装置2とを備える。
図5に示されるように、基板支持部材5の支持面5aには、回路基板3の第2面3bに実装される電子部品31を収容する第1収容凹部51が設けられる。第1収容凹部51は、実装部R11に対応する位置に設けられる。図示の例においては、2つの第1収容凹部51が形成される。なお、第1収容凹部51の数は、1または3以上であってもよい。
これにより、第3方向D3から見たときに端子側被支持部R12がコネクタ4と重ならない位置に配置される場合と比較して、端子側被支持部R12の位置を端子孔32に近づけることができる。端子側被支持部R12の位置が端子孔32に近いほど、プレスフィット端子44を端子孔32に圧入するときに回路基板3にかかる押圧力が実装部R11に伝達されることを防止する効果が大きくなる。したがって、プレスフィット端子44を端子孔32に圧入するときに回路基板3にかかる押圧力が、実装部R11に伝達されることがより効果的に防止できる。また、実装部R11の位置を端子孔32に近づけることができるため、電子部品31を端子孔32により近い位置まで実装することができる。
図20Aおよび図20Bは、実施の形態1の比較例に係る回路接続装置202の概略構成を示す図である。図20Aおよび図20Bに示されるように、回路接続装置202において第1締結部材6が設けられない場合には、コネクタ4を回路基板3に取り付けるときに、押し部材9によって回路基板3を基板支持部材5に向けて押し付けることにより回路基板3を一時的に固定することが考えられる。この場合に、端子側被支持部R12を、第3方向D3から見たときにコネクタ4と重なる位置に配置しようとすると、コネクタ4と押し部材9との干渉を避けるために、コネクタ4に押し部材9が挿通される挿通孔45を設ける必要がある。さらに、回路基板3への異物の侵入を防止するために、コネクタ4を回路基板3に取付けた後に挿通孔45を塞ぐ必要がある。したがって、回路接続装置202の製造が煩雑になる。
図8A及び図8Bに示されるように、プレスフィット端子44は、端子孔32に、上側に向けて圧入されていてもよい。この場合、コネクタ4は、回路基板3の第2面3b側に配置される。基板支持部材5は、回路基板3とコネクタ4との間に配置される。基板支持部材5には、プレスフィット端子44が挿通される端子用貫通孔57が形成される。プレスフィット端子44は、端子用貫通孔57に挿通され、端子孔32に圧入される。
以下、実施の形態2に係る回路接続装置2Aについて、図10~12Bを参照して説明する。なお、実施の形態1と同様の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
プレスフィット端子44を端子孔32に圧入するときに回路基板3にかかる押圧力を、端子側被支持部R12に加えて、第2の端子側被支持部R14によって受け止めることができる。したがって、回路基板3の歪みをより確実に抑えることができる。
プレスフィット端子44を端子孔32に圧入するときに、微細な金属屑が生じる可能性がある。第2収容凹部55Aが、端子側支持部R21と、第2の端子側支持部R24と、一対の側部R23と、により囲まれて閉空間となっているため、金属屑が第2収容凹部55Aの外部へ飛散することが防止できる。したがって、金属屑が回路基板3の各種回路等に付着して、回路の短絡等が生じることが防止できる。また、外部から第2収容凹部55Aへ異物が侵入することも防止できる。したがって、外部からの異物がプレスフィット端子44または端子孔32に付着して、回路基板3が誤作動したり、回路基板3及びコネクタ4に酸化物が生成されたりすることを防止できる。
図13A及び図13Bに示されるように、プレスフィット端子44は、端子孔32に、上側に向けて圧入されていてもよい。この場合、コネクタ4は、回路基板3の第2面3b側に配置される。基板支持部材5は、回路基板3とコネクタ4との間に配置される。基板支持部材5には、プレスフィット端子44が挿通される端子用貫通孔57が形成される。プレスフィット端子44は、端子用貫通孔57に挿通され、端子孔32に圧入される。
以下、実施の形態3に係る回路接続装置2Bについて、図14A及び図14Bを参照して説明する。なお、実施の形態1及び実施の形態2と同様の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
図15に示されるように、複数の視認孔58は、複数のプレスフィット端子44のそれぞれに対応して形成されていてもよい。また、1つの視認孔58によって2つ以上のプレスフィット端子44を視認できるように、複数の視認孔58が形成されていてもよい。
以下、実施の形態4に係る回路接続装置2Cについて、図16A及び図16Bを参照して説明する。なお、実施の形態1~実施の形態3と同様の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
第2の実装部R15を設けることにより、電子部品31、63の実装領域を拡大することができる。また、基板支持部材5によって支持される第2の端子側被支持部R14が、第2の実装部R15と端子孔32との間に配置されている。したがって、プレスフィット端子44を端子孔32に圧入するときに回路基板3にかかる押圧力を、第2の端子側被支持部R14によって受け止めることができ、この押圧力が第2の実装部R15に直接伝達されることが防止できる。したがって、回路基板3の歪みを抑えることができ、第2の実装部R15に実装される第2の電子部品63が損傷等することが防止できる。
以下、実施の形態5に係る回路接続装置2Dについて、図17を参照して説明する。なお、実施の形態1~実施の形態4と同様の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
これにより、基板支持部材5及び第1締結部材6を介して、ノイズ抑制部品31BをGNDに接続することができる。
図18に示されるように、GNDパターン71は、端子側被支持部R12において、回路基板3の第2面3bまで延びるよう形成されていてもよい。この場合、GNDパターン71は、基板支持部材5に直接接続される。ノイズ抑制部品31BのXコンデンサ及びYコンデンサは、GNDパターン71及び基板支持部材5を介して、GNDに接続される。
以下、実施の形態6に係る回路接続装置2Eについて、図19A及び図19Bを参照して説明する。なお、実施の形態1~実施の形態5と同様の機能及び作用を有する構成要素については、同一の符号を付してその説明を省略する。
第1締結部材6及び第2締結部材7は、回路基板3を基板支持部材5に固定できればよく、ネジに限定されない。
基板支持部材5は、回転電機1のケース14と一体に形成されていてもよい。
複数の端子孔32は、第1方向D1における一方側の端部に配置されてもよい。この場合、例えば、実装部R11は、第1方向D1における他方側の端部に配置されており、端子側被支持部R12は、第1方向D1において、実装部R11と端子孔32とに挟まれるように配置されていてもよい。複数の端子孔32は、第1方向D1における一方側の端部と、第2方向D2における一方側の端部とに組み合わせて配置されていてもよい。
