図4に示すように、第1ハウジング2は、絶縁性を有する樹脂材料により、第2軸D2に長い扁平な形状に形成されている。第1ハウジング2において、第2軸D2の中央部分における第3軸D3の両側は、第1軸D1から見て略矩形に切り欠かれている。第1ハウジング2は、第1軸D1から見て(以下、「平面視」ともいう)略H字状に形成されている。
第1端子3は、信号伝送用の端子であって、帯状の金属板を折り曲げることにより形成されている。また、第1端子3には、金めっきが施されている。
図5に示すように、第1特定端子31は、主片311と、端子片312と、補助片313と、を有しており、これらを一体に形成して構成されている。第1特定端子31は、第3軸D3から見てL字状の形状を有している。
図5に示すように、第1接続端子32は、延出片321と、接触片322と、つなぎ片323と、端子片324と、を有しており、これらを一体に形成して構成されている。延出片321と接触片322は、嵌合状態で第2接続端子72と物理的に接触する特定部位である接点を有している。
第1シールド4は、電磁波を遮蔽するための電磁シールドである。第1シールド4は、第1端子3及び第2端子7を流れる信号電流に対する外来ノイズ(電磁波)の影響を低減する。また、第1シールド4は、第1端子3及び第2端子7を流れる信号電流に起因するノイズ(電磁波)が、外部の電気機器等に与える影響を低減する。
図3に示すように、第1外側シールド41は、第1ハウジング2の第1外周壁24に保持される。第1外側シールド41は、複数の第1端子3を囲んでいる。第1外側シールド41は、例えば、金属板に抜き加工及び曲げ加工を施すことにより形成される。
第1内側シールド45は、複数の第1端子3のうちの2つの第1端子3の間に配置される。ここでは、第1内側シールド45は、第1特定端子31と第1接続端子32との間に配置される。
第2コネクタ5は、ソケット(メスコネクタ)であって、図1、図7~図9に示すように、第2ハウジング6と、複数(ここでは8個)の第2端子7と、第2シールド8と、を備えている。
第2ハウジング6は、絶縁性を有する樹脂材料により、第2軸D2に長い扁平な略直方体状に形成されている。第2ハウジング6において、第2軸D2の中央部分における第3軸D3の両側は、第1軸D1から見て略矩形に切り欠かれている。また、第2ハウジング6において、第3軸D3の中央部分における第2軸D2の両側は、第1軸D1から見て略矩形に切り欠かれている。
第2端子7は、信号伝送用の端子であって、帯状の金属板を折り曲げることにより形成されている。また、第2端子7には、金めっきが施されている。複数の第2端子7は、第1コネクタ1と第2コネクタ5とが嵌合した嵌合状態において、第1コネクタ1の複数の第1端子3にそれぞれ接触する。
第2特定端子71は、嵌合状態において第1特定端子31と接触して第1特定端子31と接続される。
図8に示すように、第2接続端子72は、接触片721と、ばね片722と、立ち上がり片723と、立ち下がり片724と、つなぎ片725と、端子片726と、を有しており、これらを一体に形成して構成されている。接触片721と立ち上がり片723は、嵌合状態で第1接続端子と物理的に接触する特定部位である接点を有している。
第2シールド8は、電磁波を遮蔽するための電磁シールドである。第2シールド8は、第1端子3及び第2端子7を流れる信号電流に対する外来ノイズ(電磁波)の影響を低減する。また、第2シールド8は、第1端子3及び第2端子7を流れる信号電流に起因するノイズ(電磁波)が、外部の電気機器等に与える影響を低減する。第2シールド8は、嵌合状態において、第1シールド4と接触する。
図9に示すように、第2外側シールド81は、一対の第2横シールド810と、一対の第2縦シールド820と、を備える。
第2内側シールド85は、複数の第2端子7のうちの2つの第2端子7の間に配置される。ここでは、第2内側シールド85は、第2特定端子71と第2接続端子72との間に配置される。
以下、第1コネクタ1と第2コネクタ5とが嵌合されたコネクタアセンブリ100の構造について、図1、図2、図10~図16を参照して説明する。図10は、図2のX-X線に沿った断面図である。図11は、図2のXI-XI線に沿った断面図である。図12は、図2のXII-XII線に沿った断面図である。図13は、図2のXIII-XIII線に沿った断面図である。図14は、図2のXIV-XIV線に沿った断面図である。図15は、第1コネクタ1と第2コネクタ5とを嵌合する前の状態における、図11に対応する部分でのコネクタアセンブリ100の断面図である。図16は、第1軸D1と直交する面内でのコネクタアセンブリ100の断面図である。
図10に示すように、嵌合状態において、第1コネクタ1の2個の第1特定端子31は、第2コネクタ5の2個の第2特定端子71にそれぞれ接触して電気的に接続される。これにより、第1コネクタ1が実装されている第1回路基板91と第2コネクタ5が実装されている第2回路基板92との間で、第1特定端子31及び第2特定端子71を介して信号の送受信が可能となる。
嵌合状態において、第1コネクタ1の第1外側シールド41は、第2コネクタ5の第2外側シールド81と接触して電気的に接続される。また、嵌合状態において、第1コネクタ1の第1内側シールド45は、第2コネクタ5の第2内側シールド85と接触して電気的に接続される。これにより、第1シールド4及び第2シールド8の電位は、同一のグランド電位となる。
上述のように、第1特定端子31は、高周波信号の信号電流が流れる主片311を有している。図10、図16に示すように、嵌合状態において、第1シールド4及び第2シールド8のうちで、主片311と第1シールド4又は第2シールド8との間に第2特定端子71が配置されない部位であって、かつ主片311と第1シールド4又は第2シールド8との距離が最短の部位と、主片311の幅広の面と、が対向している。
本開示の実施形態は、上記実施形態に限定されない。上記実施形態は、本開示の目的を達成できれば、設計等に応じて種々の変更が可能である。以下、上述の実施形態の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。
本変形例のコネクタアセンブリ100は、第1コネクタ1の第1シールド4の構成において、上述の実施形態のコネクタアセンブリ100と相違する。また、本変形例のコネクタアセンブリ100は、第1コネクタ1(ヘッダ)の第1ハウジング2の構成において、上述の実施形態のコネクタアセンブリ100と相違する。また、本変形例のコネクタアセンブリ100は、第2コネクタ5(ソケット)の第2シールド8の構成において、上述の実施形態のコネクタアセンブリ100と相違する。本変形例のコネクタアセンブリ100において、上述のコネクタアセンブリ100と同様の構成については、同一の符号を付して適宜説明を省略する。
一変形例において、第1端子近接部300は、第1対向部407と平行でなくてもよく、第1幅広面301の仮想面Im1への投影面積が第1幅狭面302の仮想面Im1への投影面積より大きければよい。
