　図５に示すとおり、第１分割ハウジング１６と第２分割ハウジング３０とは、第１分割ハウジング１６側から直線的に延びる前後一対の第１接続部４６と、第２分割ハウジング３０側から直線的に延びる前後一対の第２接続部４７と、屈曲容易部４８と、によって連結される。屈曲容易部４８は、第１接続部４６と第２接続部４７とを接続する。前後一対の第１接続部４６と前後一対の第２接続部４７とは、展開状態で互いに同一平面上に位置する。
　図２及び図５に示すように屈曲容易部４８は、前後の第１接続部４６及び第２接続部４７より薄肉としてある。前後の第１接続部４６と第２接続部４７とは、前後方向に延びる屈曲容易部４８を折曲げ線として、図１、図５などにおいて谷折り（第１分割ハウジング１６と第２分割ハウジング３０とが接近する方向に折曲げ）可能（容易）である。第１接続部４６は、第２接続部４７より曲げ剛性が小さく設定される。
　第１分割ハウジング１６、第１接続部４６、屈曲容易部４８、第２接続部４７及び第２分割ハウジング３０は、図１及び図５に示す展開状態において、自律的にこの展開状態を維持する程度の強度（剛性）を有する。
　図６は、中継コンタクト５０単体の斜視図である。図６を参照して、中継コンタクト５０の構造を詳細に説明する。
　中継コンタクト５０は、ばね弾性を有する銅合金（例えばリン青銅、ベリリウム銅、チタン銅）又はコルソン系銅合金の薄板を順送金型（スタンピング）を用いて図示形状に成形加工したものである。中継コンタクト５０の表面には、ニッケルメッキで下地を形成した後に、錫銅めっき又は錫めっき（あるいは金めっき）が施される。
　中継コンタクト５０は、左右方向に延びる平板状の基片５１と、基片５１の前後両側縁部の一方の端部に突設した、基片５１に対して直交する方向に延びる平板状の一対の第１ケーブル圧接片５２と、基片５１の前後両側縁部の他方の端部に突設した、基片５１に対して直交する方向に延びる平板状の一対の第２ケーブル圧接片５４と、を一体的に有している。基片５１の左右二か所には円形の位置決め孔５１ａが形成される。前後の第１ケーブル圧接片５２と第２ケーブル圧接片５４とには、基片５１側に向かって直線的に延びるスリットからなる第１圧接用溝５３と第２圧接用溝５５とがそれぞれ形成される。第１圧接用溝５３の上端開口部は、先端部５２ａにより上方に向かって広がる略Ｖ字状に形成される。第２圧接用溝５５の上端開口部は、先端部５４ａにより上方に向かって広がる略Ｖ字状に形成される。
　前後一対の第１ケーブル圧接片５２及び第２ケーブル圧接片５４は、幅狭部（くびれ部）５２ｂ、５４ｂをそれぞれ介して基片５１と接続される。左右方向に位置する第１ケーブル圧接片５２と第２ケーブル圧接片５４との対向縁部の間隔は、幅狭部５２ｂと幅狭部５４ｂとの対向縁部の間隔より狭い。幅狭部５２ｂと幅狭部５４ｂとの間には、遊び部５１ｂが設けられる。第１ケーブル圧接片５２と第２ケーブル圧接片５４との間には、インシュレータなど、他の部材が介在しない。
　中継コンタクト５０は、第１分割ハウジング１６と第２分割ハウジング３０との嵌合状態において、第１ケーブル６０及び第２ケーブル６５と導通した状態で内包される。より具体的には、中継コンタクト５０は、第１分割ハウジング１６と第２分割ハウジング３０との嵌合の際に、第１圧接用溝５３及び第２圧接用溝５５によって絶縁性の被覆６２及び被覆６７をそれぞれ切断して、第１ケーブル６０及び第２ケーブル６５同士を導通させる。中継コンタクト５０は、嵌合の際に、第１圧接用溝５３及び第２圧接用溝５５によって芯線６１及び芯線６６をそれぞれ挟持して、第１ケーブル６０及び第２ケーブル６５同士を導通させる。
　第１ケーブル６０と第２ケーブル６５とは、導電性及び可撓性を有する材料（例えば銅又はアルミニウム）からなる芯線６１、６６（撚り線又は単線）の表面をチューブ状かつ可撓性及び絶縁性を有する被覆６２、６７でそれぞれ覆ったものである。第１ケーブル６０は、配線対象物（例えば自動車など）の内部に最初から配線しかつ配線対象物の電源と接続するケーブルである。第２ケーブル６５は、第１ケーブル６０に対して後から追加で接続するケーブルである。その一端（前端）には電子機器又は電気機器（例えばカーナビゲーションシステム）などが接続される。
　図７は、絶縁ハウジング１５が展開状態からロック状態に遷移する段階のコネクタ１０、第１ケーブル６０及び第２ケーブル６５の斜視図である。図８は、絶縁ハウジング１５がロック状態にあるときのコネクタ１０、第１ケーブル６０及び第２ケーブル６５の斜視図である。図９は、図８のIX－IX矢線に沿う断面図である。
　絶縁ハウジング１５、中継コンタクト５０、第１ケーブル６０及び第２ケーブル６５を一体化して、第１ケーブル６０と第２ケーブル６５とを電気的に接続しながらコネクタ１０を組み立てるには、組み立て作業者が手などにより図１、図５に示す展開状態にある第１分割ハウジング１６のコンタクト取付溝１８に対して中継コンタクト５０の下部を嵌合させる。具体的には、遊び部５１ｂを中間凸部１８ｂに嵌合させながら基片５１をコンタクト取付溝１８の底部に嵌合させる。第１ケーブル圧接片５２の基片５１側の半部（図１、図２では下半部）を対応する固定部１８ａに嵌合させる。第２ケーブル圧接片５４の基片５１側の半部を対応する固定部１８ａに嵌合させる。基片５１の一対の位置決め孔５１ａに対して第１分割ハウジング１６の一対の位置決め突起１８ｃが嵌合するので（図２、図９参照）、中継コンタクト５０が第１分割ハウジング１６に対して位置決めされる。中継コンタクト５０を第１分割ハウジング１６に取り付けると、前後の第１ケーブル取付溝１９を通る軸線上に前後の第１圧接用溝５３が位置し、かつ、前後の第２ケーブル取付溝２０を通る軸線上に前後の第２圧接用溝５５が位置する。
　組み立て作業者が手などにより、前後の脱落防止突起３５ｃ、３６ｃ及び３５ｄ、３６ｄによる抵抗に抗して第１ケーブル６０及び第２ケーブル６５をそれぞれ押込む（図１参照）。その際、各突出片３７ａ、３８ａ、３７ｂ、３８ｂは弾性力に抗して撓み、対向する脱落防止突起３５ｃ、３６ｃ及び３５ｄ、３６ｄの間隔を広げる。第１ケーブル６０及び第２ケーブル６５が第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂにそれぞれ押し込まれると、対向する脱落防止突起３５ｃ、３６ｃ及び３５ｄ、３６ｄの間隔が狭まる。これにより、第１ケーブル６０及び第２ケーブル６５は、第１ケーブル保持溝３５ａ、３６ａの底部及び第２ケーブル保持溝３５ｂ、３６ｂの底部と脱落防止突起３５ｃ、３６ｃ及び３５ｄ、３６ｄとの間にそれぞれ挟持される。これにより第１ケーブル６０及び第２ケーブル６５は、抵抗を受けながらケーブル延長方向に移動可能である。したがって、図１及び図２に示した展開状態のコネクタ１０に対する第１ケーブル６０及び第２ケーブル６５の延長方向の位置調整が可能である。第１ケーブル６０及び第２ケーブル６５が第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂからそれぞれ離脱しようとすると、離脱を阻止する抵抗を受ける。したがって、コネクタ１０を上下逆さまにしても、第１ケーブル６０及び第２ケーブル６５が、第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂからそれぞれ容易に抜け落ちない。第１ケーブル６０及び第２ケーブル６５は、一定以上の付勢力により第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂからそれぞれ離脱させることが可能である。したがって、コネクタ１０の交換並びにコネクタ１０に着脱する第１ケーブル６０及び第２ケーブル６５の変更が容易である。
　第１ケーブル６０及び第２ケーブル６５を左右方向に並べ、第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂにそれぞれ嵌合保持した状態のまま、前後の屈曲容易部４８を中心に第２分割ハウジング３０（前後の第２接続部４７）を第１分割ハウジング１６（前後の第１接続部４６）に対して接近するように回転させる。すると、第１分割ハウジング１６側の第２ロック用突起４０が、対応する第１ロック用突起２６の傾斜面２６ａに当接する。さらに回転させると、当該第２ロック用突起４０が対応する傾斜面２６ａを下方に摺動しつつ、対応する第１ロック用突起２６が、第１分割ハウジング１６の内側方向に弾性変形する。第２接続部４７側に位置するケーブル押圧突起３２の第２押圧溝３２ｂが、第２ケーブル６５の中間部を、第２圧接用溝５５の奥側（下方）に僅かに押し込む。これにより、第２ケーブル６５の中間部が、前後の第２ケーブル圧接片５４の間の空間に入り込む。
　手などにより第２分割ハウジング３０を前後の屈曲容易部４８を中心に第１分割ハウジング１６に対して接近する方向にさらに回転させる。第２接続部４７と反対側に位置するケーブル押圧突起３２の第１押圧溝３２ａが、第１ケーブル６０の中間部を第１ケーブル圧接片５２の先端部５２ａに対して第１圧接用溝５３の延出方向又はこれに近い方向に押し当てる。したがって、第１ケーブル６０が先端部５２ａとケーブル押圧突起３２とによって挟持される。
　第１ケーブル６０と第２ケーブル６５とを中継コンタクト５０の先端部５２ａ、５４ａに載置した後に、図示を省略した一般的な工具（例えば、プライヤー）によって第１分割ハウジング１６及び第２分割ハウジング３０を、互いに接近する方向に略平行に押圧する。各第２ロック用突起４０が、対応する第１ロック用突起２６に対して係合する。第２ロック部３９の各凸壁４１が、対応する凹部２５ａと嵌合する。これにより、第１分割ハウジング１６が第２分割ハウジング３０内に収容され、第１ロック部２５と第２ロック部３９とは、嵌合した第１分割ハウジング１６及び第２分割ハウジング３０の内側で係合する。
　ケーブル押圧突起３２は、第１ケーブル６０及び第２ケーブル６５の中間部をそれぞれ第１圧接用溝５３及び第２圧接用溝５５の奥側（底面側）にさらに押し込む。したがって、第１ケーブル６０が先端部５２ａから第１圧接用溝５３の略中央部まで押し込まれる。第２ケーブル６５が先端部５４ａから第２圧接用溝５５の略中央部まで押し込まれる。このとき、ケーブル押圧突起３２の第１押圧溝３２ａ及び第２押圧溝３２ｂによる第１ケーブル６０及び第２ケーブル６５のそれぞれの押圧方向が上下方向（第１圧接用溝５３及び第２圧接用溝５５の延長方向）と略平行となる。これにより、第１圧接用溝５３の内面（左右両面）によって第１ケーブル６０の被覆６２の左右両側部が破られる。第２圧接用溝５５の内面（左右両面）によって第２ケーブル６５の被覆６７の左右両側部が破られる。したがって、絶縁ハウジング１５が閉状態に保持されたときに、第１圧接用溝５３の内面（一対の対向面）が芯線６１の両側部に対して均等且つ確実に接触（圧接）する。第２圧接用溝５５の内面（一対の対向面）が芯線６６の両側部に対して均等且つ確実に接触（圧接）する。その結果、コネクタ１０の内部において第１ケーブル６０の芯線６１と第２ケーブル６５の芯線６６とが中継コンタクト５０を介して互いに電気的に導通する。
　芯線６１、６６の両側部の一方に対して第１圧接用溝５３及び第２圧接用溝５５の内面が過度に強く当たることがないので、芯線６１、６６の一部が第１圧接用溝５３及び第２圧接用溝５５によってそれぞれ切断されることがない。そのため芯線６１、６６の機械的強度が低下しないので、第１ケーブル６０及び第２ケーブル６５に引張力が作用しても芯線６１、６６が完全に切断するおそれは小さい。したがって、第１ケーブル６０及び第２ケーブル６５と中継コンタクト５０との接触信頼性を高めることが可能である。
　第１分割ハウジング１６と第２分割ハウジング３０とが閉状態に（嵌合して）保持（ロック）された状態では、第１分割ハウジング１６の蓋部２１、２２の対向面２１ａ、２２ａが、第１ケーブル保持溝３５ａ、３６ａ及び第２ケーブル保持溝３５ｂ、３６ｂの開口部（図４の上方の開口部）の一部を塞いでいる。第１ケーブル６０は、第１分割ハウジング１６の一対の傾斜面１９ａ及び対応する第２分割ハウジング３０の傾斜面３５ｅ、３６ｅによって上下方向から挟まれる。第２ケーブル６５は、第１分割ハウジング１６の一対の傾斜面２０ａ及び対応する第２分割ハウジング３０の傾斜面３５ｆ、３６ｆによって上下方向から挟まれる。
　以下では、充填剤７０を装填した状態のコネクタ１０について主に説明する。充填剤７０は、第１分割ハウジング１６及び第２分割ハウジング３０にそれぞれ設けられる（第１充填剤７０ａ及び第２充填剤７０ｂ）。第１充填剤７０ａ及び第２充填剤７０ｂは、第１分割ハウジング１６と第２分割ハウジング３０との嵌合の際に、合着して互いに一体化してもよいし、粘着して接合面を形成してもよい。充填剤７０は、防水用ゲル、ＵＶ硬化樹脂、又は接着剤などのうち、合着性又は粘着性を有する任意の材料であってよい。
　図１０は、展開状態における絶縁ハウジング１５に充填剤７０を装填した様子を示した斜視図である。図１１は、充填剤７０を装填した絶縁ハウジング１５が展開状態からロック状態に遷移する段階を示した図９に対応する断面図である。図１２は、充填剤７０を装填した絶縁ハウジング１５が展開状態からロック状態に遷移する段階を示した図８のXII-XII矢線に沿う断面図である。図１３は、充填剤７０を装填したコネクタ１０のロック状態を示した図９に対応する断面図である。図１４は、充填剤７０を装填したコネクタ１０のロック状態を示す図８のXII－XII矢線に沿う断面図である。
　一実施形態では、図１０に示すように、第１分割ハウジング１６の内周側第１対向面１７ｂ及び第２分割ハウジング３０の内周側第２対向面３１ｂに、充填剤７０を介在させる。
　第１分割ハウジング１６の内周側第１対向面１７ｂに介在させた第１充填剤７０ａは、下面の平面形状が内周側第１対向面１７ｂと略同一であって、中継コンタクト５０の周囲を囲むように形成される。このとき、壁部２８は、中継コンタクト５０と第１充填剤７０ａとによって挟まれるように配置される。第１充填剤７０ａの高さは、第１分割ハウジング１６と第２分割ハウジング３０とが嵌合したときに、第１充填剤７０ａと第２充填剤７０ｂとが合着又は粘着する高さである。
　第２分割ハウジング３０の内周側第２対向面３１ｂに介在させた第２充填剤７０ｂは、下面の平面形状が内周側第２対向面３１ｂと略同一であり、ケーブル押圧突起３２の周囲を囲むように形成される。このとき、壁部４２は、第１押圧溝３２ａ、第２押圧溝３２ｂ及び中央突起３２ｃと第２充填剤７０ｂとを隔てる。壁部４２は、ケーブル押圧突起３２を囲繞する第２充填剤７０ｂの内周面に沿って配置される。壁部４２は、第２充填剤７０ｂよりも嵌合側、すなわち上方に突出する。突起３２ｄ、３２ｅは、壁部４２の他の部分よりも一段上方に突出した状態で形成される。第２充填剤７０ｂの高さは、第１分割ハウジング１６と第２分割ハウジング３０とが嵌合したときに、第１充填剤７０ａと第２充填剤７０ｂとが合着又は粘着する高さである。
　図１０に示す展開状態からコネクタ１０をロック状態に遷移させると、図１１及び図１２に示す状態を経て、図１３及び図１４に示すとおり、嵌合した第１分割ハウジング１６及び第２分割ハウジング３０の内部全体が充填剤７０により充填される。より詳細には、第１分割ハウジング１６と第２分割ハウジング３０とがロック状態となったときに、充填剤７０は、内周側第１対向面１７ｂと内周側第２対向面３１ｂとに密着し、かつ、中継コンタクト５０の周囲を囲繞する。
　ロック状態において、第１充填剤７０ａ及び第２充填剤７０ｂは、互いに潰し合って一度圧縮状態となり、確実に密着する。このとき、充填剤７０が合着性を有する材料により構成される場合、第１充填剤７０ａ及び第２充填剤７０ｂは、水素結合などの化学反応によって一体化する。充填剤７０が粘着性を有する材料により構成される場合、第１充填剤７０ａ及び第２充填剤７０ｂは、接合面を形成して互いに粘着する。以上により、充填剤７０は、中継コンタクト５０の周囲を密閉する。
　このとき、壁部４２は、中継コンタクト５０と充填剤７０とを隔てる。換言すると、壁部４２は、中継コンタクト５０と充填剤７０との間に配置される。壁部４２は、嵌合状態において中継コンタクト５０を囲繞する充填剤７０の内周面に沿って配置される。壁部４２の外面は、充填剤７０の内周面と対向する。壁部４２の外面は、充填剤７０の内周面と当接してもよい（図１４参照）。壁部２８は、壁部４２と左右方向に重なる（図１３参照）。壁部２８及び壁部４２は、嵌合後において二重構造となる。より具体的には、壁部２８は、嵌合方向に垂直な方向、すなわち左右方向に沿って壁部４２と隣接する。
　第１分割ハウジング１６及び第２分割ハウジング３０は、充填剤７０が過多の場合に充填剤７０の余剰分が入り込む空間Ｓをそれぞれ有する。空間Ｓは、３つの構成部からなってもよい。空間Ｓは、充填剤７０と対向する壁部４２の外面に設けられた凹部４３により構成されてもよい（図１３参照）。空間Ｓは、第２分割ハウジング３０を嵌合方向、すなわち上下方向に沿って貫通する貫通部４４により構成されてもよい（図１３及び図１４参照）。空間Ｓは、嵌合後において、充填剤７０を挟んで貫通部４４と対向する位置に設けられる凹部２７により構成されてもよい。このように、貫通部４４及び凹部２７は、第１分割ハウジング１６及び第２分割ハウジング３０が嵌合した状態で、一対の第１ロック部２５に沿って形成され、充填剤７０の上方及び下方にそれぞれ設けられる。
　第１ケーブル６０及び第２ケーブル６５は、ロック状態で充填剤７０の内側に配置される中継コンタクト５０から外側に延出する。第１ケーブル６０及び第２ケーブル６５は、中継コンタクト５０における圧接部分から前後方向に沿って外側に延出する。
　充填剤７０は、第１分割ハウジング１６の一対の第１ロック部２５の内面と当接する。図１３に示すとおり、第１ロック用突起２６及び第２ロック用突起４０の係合面２９は、その上下方向において、上下方向に沿った充填剤７０の幅内に位置する。第１分割ハウジング１６及び第２分割ハウジング３０を嵌め合わせたときに、第２ロック用突起４０の表面は、第１ロック部２５の外面と当接する。これにより形成される当接面４５は、充填剤７０と当接する第１ロック部２５の内面と略平行である。
　以上のような充填剤７０の構成により、コネクタ１０は、水又は塵埃などの外部の異物の侵入を効果的に抑制できる。
　以上のような一実施形態に係るコネクタ１０は、嵌合によって圧縮状態となった充填剤７０の内側への侵入を、壁部４２によって抑制できる。これによりコネクタ１０は、嵌合状態における充填剤７０同士の接触面の圧力を低下させず、防水性能を高めることができる。コネクタ１０は、嵌合後において充填剤７０の中継コンタクト５０への侵入を抑制できる。これにより、コネクタ１０は、中継コンタクト５０と各ケーブルの芯線６１、６６との接触不良を抑制できる。
　コネクタ１０は、壁部４２が充填剤７０の内周面に沿って配置されることで、中継コンタクト５０を囲繞する充填剤７０の内側への侵入を全方向にわたって効果的に抑制できる。これにより、コネクタ１０は、上記の関連する効果をより顕著に奏する。
　コネクタ１０は、壁部２８及び壁部４２の二重構造により、対応する部分の壁としての堅牢性を向上できる。これにより、コネクタ１０は、充填剤７０の圧縮に伴う内側への圧力が加わったとしても、壁部２８及び壁部４２の破損を抑制できる。
　図１１に示すとおり、コネクタ１０は、壁部４２が充填剤７０よりも嵌合側に大きく突出することで、充填剤７０同士が当接する前に充填剤７０を内側の空間と隔てることができる。これにより、コネクタ１０は、嵌合の途中段階においても圧縮状態にある充填剤７０の内側への侵入を対応する部分で効果的に抑制できる。図１２に示すとおり、壁部４２が充填剤７０よりも嵌合側に突出することで、コネクタ１０は、第１分割ハウジング１６内の充填剤７０を外側に誘い込んで、壁部４２の外側で充填剤７０同士を当接させることができる。
　コネクタ１０は、空間Ｓを有することで、嵌合の際に充填剤７０の余剰分を吸収して溜めこむことができる。したがって、コネクタ１０は、嵌合の際の充填剤７０の圧縮率を調整できる。換言すると、コネクタ１０は、充填剤７０の圧縮率の個体ごとのばらつきを抑制できる。コネクタ１０は、定められた位置にあえて空間Ｓを設けることで、充填剤７０の余剰分が意図しない位置に拡散することを抑制できる。これにより、コネクタ１０は、嵌合力及び接触面の圧力の低下を抑制できる。コネクタ１０は、防水性能の悪化を抑制できる。このように、コネクタ１０では、充填剤７０の余剰分は、防水性能に影響を及ぼさない。コネクタ１０は、壁部４２と空間Ｓとの相乗効果によって、充填剤７０の中継コンタクト５０への侵入をより効果的に抑制できる。
　コネクタ１０は、空間Ｓが凹部４３により構成されることで、圧縮状態となった充填剤７０のうち内側へと押し出される余剰分を溜めこむことができる。
　コネクタ１０は、空間Ｓが貫通部４４により構成されることで、圧縮状態となった充填剤７０のうち外側へと押し出される余剰分を溜めこむことができる。コネクタ１０は、貫通部４４が上方に貫通していることで、充填剤７０の余剰分を外部へと逃がすことができる。コネクタ１０は、貫通部４４から充填剤７０を視認できるため、充填剤７０の量に関する視覚的な確認を容易とする。したがって、コネクタ１０は、製造の際に充填剤７０の量を適切に調整することができ、生産性の向上に寄与する。
　コネクタ１０は、空間Ｓが凹部２７により構成されることで、圧縮状態となった充填剤７０のうち外側へと押し出される余剰分を溜めこむことができる。コネクタ１０は、凹部２７と貫通部４４との相乗効果によって、外側へと押し出される余剰分をより効率的に溜めこむことができる。
　コネクタ１０は、中継コンタクト５０がケーブルと導通した状態で内包されることで、第１ケーブル６０及び第２ケーブル６５同士を安全に接続できる。コネクタ１０は、製品としての信頼性を向上できる。
　コネクタ１０は、ケーブルが充填剤７０の内側に配置される中継コンタクト５０から外側に延出することで、中継コンタクト５０との接触部を外部の異物から保護しつつ、ケーブルを他の電子機器などに接続できる。
　コネクタ１０は、第１圧接用溝５３及び第２圧接用溝５５によって第１ケーブル６０及び第２ケーブル６５の芯線６１、６６をそれぞれ挟持した状態で導通させることで、接触信頼性を高めることができる。これにより、コネクタ１０は、第１ケーブル６０及び第２ケーブル６５の電気的な接続を確実なものとできる。
　本開示は、その精神又はその本質的な特徴から離れることなく、上述した実施形態以外の他の所定の形態で実現できることは当業者にとって明白である。したがって、先の記述は例示的であり、これに限定されない。開示の範囲は、先の記述によってではなく、付加した請求項によって定義される。あらゆる変更のうちその均等の範囲内にあるいくつかの変更は、その中に包含される。
　第１分割ハウジング１６に中継コンタクト５０が取り付けられるとして説明したが、これに限定されない。中継コンタクト５０は、第２分割ハウジング３０に取り付けられてもよいし、第１分割ハウジング１６及び第２分割ハウジング３０の両方に取り付けられてもよい。
　第１分割ハウジング１６及び第２分割ハウジング３０のそれぞれに第１充填剤７０ａ及び第２充填剤７０ｂが充填されるとして説明したが、これに限定されない。コネクタ１０は、適切な防水性を得ることができるのであれば、第１分割ハウジング１６及び第２分割ハウジング３０のいずれか一方のみが充填剤７０を有するように構成されてもよい。
　上記では、第１分割ハウジング１６が壁部２８を有し、第２分割ハウジング３０が壁部４２を有するとして説明したが、これに限定されない。第１分割ハウジング１６及び第２分割ハウジング３０の一方のみが、壁部に相当する構成を有してもよい。壁部２８及び壁部４２の構成を入れ替えて、第１分割ハウジング１６が壁部４２を有し、第２分割ハウジング３０が壁部２８を有してもよい。この場合、例えば、壁部４２は、嵌合前において第１充填剤７０ａと中継コンタクト５０とを隔ててもよい。さらに、壁部４２は、嵌合前において中継コンタクト５０を囲繞する第１充填剤７０ａの内周面に沿って配置されてもよい。これにより、コネクタ１０は、上述した対応する効果を奏する。壁部２８が中継コンタクト５０の周囲の一部にのみ形成され、嵌合後において対応する部分のみが二重構造になるとして説明したが、これに限定されない。壁部２８は、中継コンタクト５０を囲繞するように形成され、嵌合後において中継コンタクト５０の周囲全体にわたって壁部４２と共に二重構造を形成してもよい。壁部２８及び壁部４２は、相手方の充填剤７０に対する誘い込み性を向上させるために、嵌合側に向かうほど先細りとなるように形成されてもよい。
　壁部４２は、嵌合状態において中継コンタクト５０を囲繞する充填剤７０の内周面に沿って配置されるとして説明したが、これに限定されない。壁部４２は、第１分割ハウジング１６及び第２分割ハウジング３０の内部における充填剤７０の配置態様に対応する形状で適宜形成されてもよい。
　コネクタ１０は、適切な量の充填剤７０を正確に装填でき、その余剰分が発生しないのであれば、空間Ｓを有さなくてもよい。
　空間Ｓは、凹部４３、貫通部４４及び凹部２７の３つの構成部からなるとして説明したが、これに限定されない。空間Ｓは、充填剤７０の余剰分を収容して防水性能悪化の抑制などの効果に寄与するのであれば、任意の態様で形成されてもよい。
　中継コンタクト５０は、第２ケーブル６５を圧接するタイプであるが、第２ケーブル６５を圧着するタイプであってもよい。この場合、第２ケーブル６５が予め中継コンタクト５０に圧着接続され、この状態で中継コンタクト５０が第１分割ハウジング１６に装着される。この実施形態では、中継コンタクト５０の一対の第１圧接用溝５３及び第２圧接用溝５５の一方の代わりに、ケーブル圧着端子が形成される。第２分割ハウジング３０には、残存する圧接用溝に対応させて一つのケーブル支持腕部３５又は３６が設けられる。
　逆に、各ケーブルのコネクタ１０によって支持された部位の延長方向に対して直交又は略直交する方向に並べた３本以上のケーブルがコネクタ１０により接続されてもよい。この場合、一つの中継コンタクトに（左右方向に並んだ）三対以上の圧接用溝が形成されてもよい。複数の中継コンタクトのそれぞれに圧接用溝が形成され、少なくとも一つの中継コンタクトに二対以上の圧接用溝が形成されて、各圧接用溝によってケーブル（芯線）が圧接されてもよい。
