As shown in FIG. 4, the shape of the lightening hole 34 as viewed from the rear is a rectangular shape having a size that is slightly larger in the vertical direction than in the horizontal direction, and is different from the through seal hole 31. Since the lightening hole 34 is slightly smaller than the terminal introduction port 42 of the rear holder 40, the entire shape can be seen from the rear with the rear holder 40 attached. In addition, as shown in FIG. 5, the corner | angular part of the lightening hole 34 is made into the round part 34A.
　次に、雌ハウジング２０の組み付け手順の一例を説明する。
　まず、雌ハウジング２０の収容凹部２８に防水ゴム栓３０を嵌着し、続いて、収容凹部２８にリアホルダ４０を嵌めこむ。すると、リアホルダ４０の係止部４１が雌ハウジング２０の被係止部２９に嵌合して係止し、リアホルダ４０が雌ハウジング２０に固定される。 Next, an example of the assembly procedure of the female housing 20 will be described.
First, the waterproof rubber plug 30 is fitted into the housing recess 28 of the female housing 20, and then the rear holder 40 is fitted into the housing recess 28. Then, the locking portion 41 of the rear holder 40 is fitted and locked to the locked portion 29 of the female housing 20, and the rear holder 40 is fixed to the female housing 20.
　次いで、電線Ｗの端末部に固着された雌端子金具１０を、リアホルダ４０の端子導入口４２から前方に挿入する。このとき、リアホルダ４０の端子導入口４２を介して貫通シール孔３１と肉抜き孔３４とを目視することができるから、誤って肉抜き孔３４に雌端子金具１０を挿入することを防ぐことができる。 Next, the female terminal fitting 10 fixed to the terminal portion of the electric wire W is inserted forward from the terminal introduction port 42 of the rear holder 40. At this time, since the through seal hole 31 and the lightening hole 34 can be visually observed through the terminal introduction port 42 of the rear holder 40, it is possible to prevent the female terminal fitting 10 from being erroneously inserted into the lightening hole 34. it can.
　防水ゴム栓３０の貫通シール孔３１に雌端子金具１０が挿入されると、貫通シール孔３１の周囲が雌端子金具１０に押されて肉抜き孔３４に逃げ、貫通シール孔３１が押し広げられる。そして、雌端子金具１０は貫通シール孔３１の前方に抜け出し、雌ハウジング２０のキャビティ２１に収容され、ランス２２に係止される。また、貫通シール孔３１は電線Ｗによって液密状に塞がれる。以上により、雌ハウジング２０の組み付け作業が完了する。 When the female terminal fitting 10 is inserted into the through-seal hole 31 of the waterproof rubber plug 30, the periphery of the through-seal hole 31 is pushed by the female terminal fitting 10, escapes to the lightening hole 34, and the through-seal hole 31 is pushed wide. . Then, the female terminal fitting 10 comes out forward of the through seal hole 31, is accommodated in the cavity 21 of the female housing 20, and is locked to the lance 22. Further, the through seal hole 31 is closed in a liquid-tight manner by the electric wire W. Thus, the assembly operation of the female housing 20 is completed.
　次に、上記のように構成された実施例の作用および効果について説明する。
　本実施例の防水コネクタＣの雌ハウジング２０は、電線Ｗの端末部に固着された雌端子金具１０が後方から挿入可能な複数のキャビティ２１を有し、そのうちのいくつかが雌端子金具１０が挿入されない空きキャビティ２１Ｖとされている。雌ハウジング２０の後面側には、防水ゴム栓３０が装着されている。そして、防水ゴム栓３０のうち電線Ｗが挿入されるキャビティ２１に対応する位置には、電線Ｗの外周面に液密状に密着可能とされた貫通シール孔３１が設けられ、空きキャビティ２１Ｖに対応する位置には、閉鎖壁３３と、この閉鎖壁３３から前面側および後面側に抜ける肉抜き孔３４が設けられている。 Next, operations and effects of the embodiment configured as described above will be described.
