The peripheral wall portion 23 of the male housing 21 is inserted and fitted between the terminal accommodating portion 34 and the hood portion 33.

また、矩形ブロック状の端子収容部３４の外周面３４ａの前側には、段差状に切り欠かれた段差部３４ｂを有している。この段差部３４ｂにパッキン４０が嵌め込まれている。 Further, a step portion 34b notched in a step shape is provided on the front side of the outer peripheral surface 34a of the rectangular block-shaped terminal accommodating portion 34. The packing 40 is fitted in the stepped portion 34b.

パッキン４０は四角環板状に形成されていて、その外周面４０ａに複数（この実施形態では３つ）のリップ部（リブ）４１を山状に一体突出形成してある。 The packing 40 is formed in the shape of a square ring plate, and a plurality of (three in this embodiment) lip portions (ribs) 41 are integrally projected in a mountain shape on the outer peripheral surface 40a thereof.

そして、図２に示すように、雄雌両ハウジング２１，３１の嵌合時に、パッキン４０の前面４０ｂが雄ハウジング２１の嵌合面２２ａに弾性密着すると共に、パッキン４０の複数のリップ部４１のうちの最前列のリップ部４１が雄ハウジング２１の４箇所の水抜き孔２４をそれぞれ塞ぐようになっている。 Then, as shown in FIG. 2, when the male and female housings 21 and 31 are fitted, the front surface 40b of the packing 40 is elastically adhered to the fitting surface 22a of the male housing 21, and the plurality of lip portions 41 of the packing 40 are in close contact with each other. The lip portion 41 in the front row of the male housing 21 closes each of the four drain holes 24 of the male housing 21.

尚、図２に示すように、雄端子２７には電線２８が電気的に接続されている。また、雌端子３７は電線３８が電気的に接続された状態でゴム栓３９を介して端子収容部３４の端子収容室３５内に収容されている。さらに、図３に示すように、端子収容部３４の前面３４ｃには、雄端子２７が挿入される貫通孔３４ｄを形成してある。また、雄雌両ハウジング２１，３１の嵌合時に、パッキン４０のリップ部４１が雄ハウジング２１の周壁部２３の内周面２３ａに弾性密着されるようになっている。 As shown in FIG. 2, the electric wire 28 is electrically connected to the male terminal 27. Further, the female terminal 37 is accommodated in the terminal accommodating chamber 35 of the terminal accommodating portion 34 via the rubber stopper 39 in a state where the electric wire 38 is electrically connected. Further, as shown in FIG. 3, a through hole 34d into which the male terminal 27 is inserted is formed in the front surface 34c of the terminal accommodating portion 34. Further, when the male and female housings 21 and 31 are fitted, the lip portion 41 of the packing 40 is elastically brought into close contact with the inner peripheral surface 23a of the peripheral wall portion 23 of the male housing 21.

以上実施形態の防水コネクタ１０によれば、図２に示すように、雄ハウジング２１の雌ハウジング３１との嵌合面２２ａに、雄ハウジング２１の外周面２１ａまで延びる水抜き孔２４を４箇所設けたことにより、雄雌両ハウジング２１，３１の嵌合動作中に内部に溜まった水Ｗを水抜き孔２４から外へ押し出して排出することができる。 According to the waterproof connector 10 of the above embodiment, as shown in FIG. 2, four drain holes 24 extending to the outer peripheral surface 21a of the male housing 21 are provided on the fitting surface 22a of the male housing 21 with the female housing 31. As a result, the water W accumulated inside during the fitting operation of the male and female housings 21 and 31 can be pushed out from the drain hole 24 and discharged.

また、雄雌両ハウジング２１，３１の嵌合時にパッキン４０の前面４０ｂを雄ハウジング２１の嵌合面２２ａに弾性密着させたことにより、雄雌両ハウジング２１，３１の嵌合後に漏電（隣接する端子収容室３５，３５に収容された雌端子３７，３７間のリーク）の発生を防止することができる。 Further, when the male and female housings 21 and 31 are fitted, the front surface 40b of the packing 40 is elastically brought into close contact with the fitting surface 22a of the male housing 21, so that electricity leaks (adjacent) after the male and female housings 21 and 31 are fitted. It is possible to prevent the occurrence of a leak between the female terminals 37 and 37 housed in the terminal housing chambers 35 and 35).

さらに、図２及び図３に示すように、雄雌両ハウジング２１，３１の嵌合時や嵌合後、雄ハウジング２１の水抜き孔２４をパッキン４０の最前列のリップ部４１で塞ぐことで、外部からの水Ｗの浸入を確実に防止することができる。 Further, as shown in FIGS. 2 and 3, the drain holes 24 of the male housing 21 are closed by the lip portion 41 in the front row of the packing 40 during and after the fitting of the male and female housings 21 and 31. , It is possible to surely prevent the intrusion of water W from the outside.

尚、前記実施形態によれば、雄ハウジングの矩形ブロック状の本体部の嵌合面の四隅の角部に、その外周面まで貫通する水抜き孔を４つ穿設したが、水が溜まり易い下側の左右の角部にそれぞれ穿設された水抜き孔の各間に少なくとも１つの水抜き孔を更に穿設するようにしても良い。 According to the above embodiment, four drain holes penetrating to the outer peripheral surface of the male housing are provided at the four corners of the fitting surface of the rectangular block-shaped main body of the male housing, but water tends to collect. At least one drain hole may be further formed between each of the drain holes formed in the lower left and right corners.
