Abstract
【解決手段】肩部13の内側に、閉壁14aに続き先端側を後側開口22に臨ませ、板厚方向に可撓性を有する突片状の可撓係止片17を設け、可撓係止片17の先端側に、可撓係止片17の板厚方向に突出する係止用突部18を設け、この係止用突部18を電線誘導部35の側壁36に設けられた係止枠37に係合させることで、保護キャップ10をハーネスプロテクタ30に係止させる。また、両側の可撓係止片17,17の間に、一方から他方へワイヤハーネス45を挿通させる電線挿通部19を設ける。

Claims (5)
- 側壁部の内側に、相手部品の係合部に係合する係止部が設けられた保護キャップにおいて、
前記係止部が、前記側壁部の奥側の閉塞された壁部に続き、先端側を前記相手部品に対する取付方向に突出させ、板厚方向に可撓性を有する突片状の可撓係止片であり、該可撓係止片の先端側に、該可撓係止片の板厚方向に突出する係止用突部が設けられたことを特徴とする保護キャップ。 - 前記相手部品がハーネスプロテクタであり、両側の前記係止部の間で一方から他方へ該ワイヤハーネスを挿通させる電線挿通部が形成されたことを特徴とする請求項1記載の保護キャップ。
- 固定側の雌金型に対する可動側の雄金型に二つの分割金型を用い、該二つの分割金型の対向面の間でアンダーカットを成形し、一方の分割金型を先に離型させた後、該アンダーカットを撓ませつつ、他方の分割金型を該一方の分割金型と同一方向に強制的に離型させることを特徴とする射出成形品の製造方法。
- 前記一方の分割金型の対向面を平坦面とし、前記他方の分割金型の対向面を凹面として、前記アンダーカットに対するキャビティを形成することを特徴とする請求項3記載の射出成形品の製造方法。
- 請求項1又は2記載の保護キャップを成形することを特徴とする請求項3又は4記載の射出成形品の製造方法。
