Description
リテーナ50A,50Bが各端子保持部40A,40Bのリテーナ装着孔48内に嵌着され、かつ所定の仮係止位置にある状態で、各端子保持部40A,40Bの各端子収容室45内に各端子30A,30BがハウジングH1、H2の外部から内部に向かって挿入される。この挿入された端子30A,30Bには当該端子保持部40A,40B内のランスが係合して当該端子30A,30Bが係止される(一次係止)。これにより、各端子30A,30Bが上下2段にわたって配列され、かつ、上下の端子30A(30B)の接触突部35aが内側を向く姿勢で各端子30A,30Bが端子保持部40A,40B内に保持される。
前記第1ハウジングH1の第1基板保持部20A内にその開口から回路基板10がその第1縁部12Aを先頭にして挿入される。具体的に、回路基板10は、前記第1基板保持部20A側の側壁24Aの案内溝25Aの案内を受けながら正確に基板挿入方向に沿って挿入され、その先頭の第1縁部12Aが第1端子保持部40A側の中間壁44の前端44aに突き当たる位置まで到達する。これにより、当該第1縁部12Aの両面に設けられた各第1接続用導体14Aが各第1端子30Aの接触突部35aに同時に接触する状態が形成される。なお、このように第1基板保持部20A内に回路基板10が挿入されると、上側列の各端子30Aの本体部35が上側に、下側列の各端子30Aの本体部35が下側にそれぞれ押し遣れる。これにより、図7に示すように、押圧端部36aが窓37a内に没入するように弾性押圧片36が撓み変形し、その弾発力で本体部35が回路基板10側に押圧されて前記接触突部35aが第1接続用導体14Aに圧接する。その結果、第1端子30Aは、接触突部35aの接触面が回路基板10の接続用導体14Aの全域又はそれに近い領域に亘って接触する。
前記と同様にして、第2ハウジングH2の第2基板保持部20B内にその開口から回路基板10がその第2縁部12Bを先頭にして挿入される。図示を省略するが、この場合も、上側列の各端子30Bの本体部35が上側に、下側列の各端子30Bの本体部35が下側にそれぞれ押し遣れる。これにより、押圧端部36aが窓37a内に没入するように弾性押圧片36が撓み変形し、その弾発力で本体部35が回路基板10側に押圧されて前記接触突部35aが第2接続用導体14Bに圧接する。その結果、第2端子30Bは、接触突部35aの接触面が回路基板10の接続用導体14Bの全域又はそれに近い領域に亘って面接触する。
