Connector housing and its manufacturing mehtod



(57)【要約】 【課題】 側壁や端子収容室の隔壁への樹脂材の充填不 足を防止する。 【解決手段】 内部に複数の端子収容室9を有し、両側 に少なくとも薄肉の側壁部6を有するコネクタハウジン グ1で、薄肉の側壁部6の中央にショートショット防止 用のリブ8を一体形成した。リブ8は、薄肉の側壁部6 に続く厚肉の側壁部7よりも外側に突出している。リブ 8は、端子収容室9の隔壁15の延長上に設置されてい る。リブ8は隔壁15よりも厚肉に形成されている。コ ネクタハウジング1の外壁5に対応してランナ3のゲー トを配置し、ゲートから成形金型内に溶融した樹脂材を 注入してコネクタハウジング1を形成する方法で、外壁 5の一部である薄肉の側壁部6にショートショット防止 用のリブ8を一体に形成させる。
PROBLEM TO BE SOLVED: To prevent the filling insufficiency of resin materials to a sidewall and partition wall of terminal accommodation room. SOLUTION: This is a connector housing 1 that has plural terminal accommodation rooms 9 in the inner part, and that has at least thin-walled side wall portions 6 on both sides, and a rib 8 for short circuit shot prevention at the center of the thin-walled side wall portion 6 is formed by one-piece molding. The rib 8 protrudes toward outside the thick-walled sidewall portion 7 that continues to a thin-walled sidewall portion 6. The rib 8 is installed in the extension of partition wall 15 of the terminal accommodation room 9. The rib 8 is formed with a thicker wall than that of the partition wall 15. In correspondence to an external wall 5 of the connector housing 1, a gate of runner 3 is arranged, and the rib 8 for short circuit shot prevention of thin-walled side wall portion 6 that is a part of external wall 5 is formed by integrally molding by a method where the connector housing 1 is formed by injecting molten resin materials from the gate into a molding die.
