(2-1)各コネクタCA,CBへ電線40を接続する接続工程
この工程では、第1コネクタCA及び第2コネクタCBにそれぞれ電線40を接続する。具体的に、各電線40の端末に、予め電線側端子20A,20Bを圧着しておく。電線側端子20A,20Bを、端子収容室136内にそれぞれ挿入する。電線側端子20A,20Bを、ランス32bによって、端子収容室136内に係止する。
この工程では、まず、図21に示すように、ベース部材50を組み付け用治具100の上面102上に載置して、ベース部材50を組み付け用治具100に仮係止する。このとき、仮係止突起105A,105Bは、ベース部材50のボルト挿通孔55A,55Bにそれぞれ挿入される。案内突起106A,106Bは、ベース部材50の各案内突起挿通孔56aにそれぞれ挿入される。また、ベース部材50の載置面52は、上方を向くように配置される。この仮係止状態において、各係止突起挿入孔104aの位置は、ベース部材50の各カバー係止孔54aの位置と合致する。
この工程では、第1コネクタCAを電子回路体10に結合させて、第1コネクタCAに保持されている第1電線側端子20Aと第1回路側端子14Aとを嵌合させる。また、第2コネクタCBを電子回路体10に結合させて、第2コネクタCBに保持されている第2電線側端子20Bと第2回路側端子14Bとを嵌合させる。
