図9,10にも示されるように、第1コネクタ12は、金属製の筐体20から外方に突出する第1端子金具16と、第1端子金具16の周囲を囲って筐体20から外方に突出する金属製のフード部22とを備えている。すなわち、筐体20に対して第1端子金具16とフード部22とは同方向に突出しており、実施形態1では、第1端子金具16とフード部22とが何れも筐体20に対して上方に突出している。また、第1コネクタ12には、一対の第1端子金具16,16が設けられており、フード部22の内側において一対の第1端子金具16,16が左右方向で相互に離隔して配置されている。
筐体20は、平面視において矩形状とされた矩形板部46を備えており、矩形板部46の前方部分には、第1コネクタハウジング30が挿通される挿通孔48が形成されている。挿通孔48は、前後方向寸法に比して左右方向寸法の大きな略長円形状とされている。また、矩形板部46において挿通孔48よりも後方部分には、後述する締結ボルト190が締結されるボルト締結穴50、および上記のボルト44が締結されるボルト締結穴52が設けられている。実施形態1では、各ボルト44が締結される一対のボルト締結穴52,52が左右方向で相互に離隔しており、これら一対のボルト締結穴52,52の左右方向間に締結ボルト190が締結されるボルト締結穴50が設けられている。
前述のように、第1コネクタ12には筐体20から上方に突出するフード部22が設けられており、実施形態1では、フード部22が筐体20に対して一体的に形成されている。図9,10にも示されるように、フード部22は、所定の上下方向寸法を有しているとともに、筐体20における挿通孔48の周囲の三方を囲うように設けられている。すなわち、フード部22は、挿通孔48の前方に位置する前壁部54と、挿通孔48の左右両側に位置する両側壁部56,56とを備えている。換言すれば、これら前壁部54および両側壁部56,56に囲まれる領域の内側に挿通孔48が設けられている。これにより、フード部22は、突出側開口部である上方開口部58と、側方開口部である後方開口部60とを備えている。
第2コネクタ14は、図3や図12等にも示されるように、被覆電線72の端末に接続されて第1端子金具16と接続される第2端子金具18と、第2端子金具18を収容する絶縁性のハウジングである第2コネクタハウジング74と、第2コネクタハウジング74の外面側となる上面側に固定的に配設される金属製の平板部76と、を備えている。また、第2コネクタ14は、第2コネクタハウジング74に設けられた電線引出口78から延出する被覆電線72を覆うシールド部材としての編組線80と接続されて電線引出口78を囲うシールドブラケット82を、さらに含んでいる。実施形態1では、一対の被覆電線72,72および第2端子金具18,18が設けられており、各被覆電線72および各第2端子金具18が、左右方向で相互に対向している。
第2端子金具18は、第1端子金具16における柱状接続部24が圧入される筒状接続部84を有していればその具体的な構造は限定されるものではなく、例えば特開2021-28899号公報に記載の雌端子(10)のような構造が採用され得る。より詳細には、実施形態1の第2端子金具18は、第2端子金具本体86と、第2端子金具本体86の先端部(前端部)に取り付けられる弾性部材としてのクリップばね88とを含んで構成されている。
第2端子金具本体86は、全体として略帯状とされた金属平板を所定の形状にプレス加工等することで形成されている。第2端子金具本体86は上述の筒状接続部84を有しており、実施形態1では、略円筒形状とされた筒状接続部84が上下方向両側に開口している。この筒状接続部84は、図4,5にも示されるように、それぞれ略半円筒形状とされた左方に位置する第1周壁部90と右方に位置する第2周壁部92とから構成されており、これら第1周壁部90と第2周壁部92とが左右方向で相互に対向している。
クリップばね88は、第2端子金具本体86の先端部に装着されることで、各先端側板部106を相互に接近する方向に付勢して、各先端側板部106の後方に接続された第1および第2周壁部90,92へ相互に接近する方向の付勢力を及ぼすようになっている。クリップばね88は、図5や図12に示されるように、前後方向視において略矩形状とされた連結板112と、連結板112の左右方向両端部から後方に突出して互いに接近する方向に傾斜する一対の押さえ片114,114を有している。各押さえ片114の前後方向中間部分には屈曲部分116が設けられており、各押さえ片114の突出先端部は、各屈曲部分116から相互に離隔する方向に延び出している。したがって、各押さえ片114の対向距離は各屈曲部分116の形成部分において最も小さくされており、これら各屈曲部分116の間の隙間が、クリップばね88に対して第2端子金具本体86を挿し込むための挿込口118である。
図11,12にも示されるように、第2コネクタハウジング74は、第2コネクタハウジング本体124と、第2コネクタハウジング本体124の下方開口部126に取り付けられるフロントリテーナ128とを含んで構成されている。
ここにおいて、第2コネクタハウジング本体124は合成樹脂と金属の複合材として形成されており、第2コネクタハウジング本体124において外面側となる上壁部132において金属製の平板部76が固定的に配設されている。具体的には、平板部76が、上壁部132の上面に固着されている。平板部76は、平面視において略矩形状であり、左壁部136および右壁部138よりも左右方向外方へ突出する左右方向寸法を有しているとともに、平面視の投影において前方壁部142よりも前方まで突出している。なお、平板部76における後端部は上方に屈曲されており、上方突出部153が構成されている。
以下、第1コネクタ12と第2コネクタ14とを嵌合してコネクタアセンブリ10を組み立てる方法の具体的な一例を説明する。なお、コネクタアセンブリ10の組立方法は、以下に記載の態様に限定されるものではない。
以上、本開示の具体例として、実施形態1について詳述したが、本開示はこの具体的な記載によって限定されない。本開示の目的を達成できる範囲での変形、改良等は本開示に含まれるものである。例えば次のような実施形態の変形例も本開示の技術的範囲に含まれる。
