Abstract
Description
複数の端子収容室が形成されたハウジングと、
複数の前記端子収容室に個別に取り付けられる複数の端子金具と、
複数の前記端子金具に対して溶接によって固着されるフレキシブルケーブルとを備え、
前記ハウジングには、複数の前記端子金具と前記フレキシブルケーブルとの溶接部分を露出させる開口部が形成されている。
複数の端子収容室が形成されたハウジングに、開口部を形成した上で、
複数の前記端子収容室に、複数の端子金具を個別に取り付け、
前記ハウジングとフレキシブルケーブルとを位置合わせすることによって、複数の前記端子金具と前記フレキシブルケーブルとの溶接部分を前記開口部に露出させ、
複数の前記端子金具と前記フレキシブルケーブルとを溶接によって固着する。
最初に本開示の実施形態を列記して説明する。
第1の開示のフレキシブルケーブル用コネクタは、
(1)複数の端子収容室が形成されたハウジングと、複数の前記端子収容室に個別に取り付けられる複数の端子金具と、複数の前記端子金具に対して溶接によって固着されるフレキシブルケーブルとを備え、前記ハウジングには、複数の前記端子金具と前記フレキシブルケーブルとの溶接部分を露出させる開口部が形成されている。第1の開示によれば、複数の端子金具を端子収容室に収容する工程と、フレキシブルケーブルとハウジングを位置合わせする工程と、複数の端子金具とフレキシブルケーブルを溶接する工程とによって、フレキシブルケーブル用コネクタを組み付けることができる。溶接後は、開口部において溶接状態を確認できるので、溶接状態確認のために端子金具を端子収容室から外す工程が不要である。複数の端子金具は、端子収容室に取り付けることによって整列した状態になるので、端子金具を整列させるために、治具に対して複数の端子金具を着脱させる工程が不要である。治具に対する端子金具の着脱工程が不要な分、組付け工程を削減することができる。
(5)複数の端子収容室が形成されたハウジングに、開口部を形成した上で、複数の前記端子収容室に、複数の端子金具を個別に取り付け、前記ハウジングとフレキシブルケーブルとを位置合わせすることによって、複数の前記端子金具と前記フレキシブルケーブルとの溶接部分を前記開口部に露出させ、複数の前記端子金具と前記フレキシブルケーブルとを溶接によって固着する。第2の開示によれば、溶接後は、開口部において溶接状態を確認できるので、溶接状態確認のために端子金具を端子収容室から外す工程が不要である。複数の端子金具は、端子収容室に取り付けることによって整列した状態になるので、端子金具を整列させるために、治具に対して複数の端子金具を着脱させる工程が不要である。治具に対する端子金具の着脱工程が不要な分、組付け工程を削減することができる。
