Waterproofing is achieved by deforming and adhering.

また、図８、図９に示すように、一対の雌雄ハウジング１１，３１が嵌合した際に、嵌合検知部材２０のアーム部２３が雄ハウジング３１のロック部３５で持ち上げられて、嵌合検知部材２０の本係止への移行が可能となる。この際、図９に示すように、嵌合検知部材２０の撓み防止部２２は、雄ハウジング３１のフード部３３を押さえていない。 Further, as shown in FIGS. 8 and 9, when the pair of male and female housings 11 and 31 are fitted, the arm part 23 of the fitting detection member 20 is lifted by the locking part 35 of the male housing 31, The detection member 20 can now be fully locked. At this time, as shown in FIG. 9, the deflection preventing portion 22 of the fitting detection member 20 does not press the hood portion 33 of the male housing 31.

そして、図１０、図１２に示すように、嵌合検知部材２０の操作部２１をその前面２１ａが雌ハウジング１１の外側フード部１３の切欠部１４の当接規制部（縁部）１４ａに当たるまで押圧操作し、嵌合検知部材２０を本係止させる。この嵌合検知部材２０の本係止により、図１３、図１４に示すように、一対の雌雄ハウジング１１，３１の嵌合が正規の嵌合状態であることを検知することができる。 Then, as shown in FIGS. 10 and 12, the operating section 21 of the fitting detection member 20 is pressed until the front surface 21a thereof hits the contact regulating section (edge) 14a of the notch section 14 of the outer hood section 13 of the female housing 11. A pressing operation is performed to permanently lock the fitting detection member 20. By fully locking the fitting detection member 20, it is possible to detect that the pair of male and female housings 11, 31 are properly fitted, as shown in FIGS. 13 and 14.

また、図１２～図１４に示すように、嵌合検知部材２０が本係止された状態において、嵌合検知部材２０が雄ハウジング３１のロック部３５と雌ハウジング１１の外側フード部１３の間に入り込む。かつ、嵌合検知部材２０の撓み防止部２２が外側フード部１３とフード部３３との間に入り込み、パッキン１８の反発力によって雄ハウジング３１のフード部３３が矢印Ｙの方向に変位する動きを撓み防止部２２の押圧部２２ｂで押さえる。また、撓み防止部２２の押圧部２２ｂは、内側に突出するようにＬ字状に形成されているので、この内側に突出する押圧部２２ｂで雄ハウジング３１のフード部３３をより確実に押さえてその変形を防ぐことができる。このように、嵌合検知部材２０の撓み防止部２２の押圧部２２ｂと雌ハウジング１１の外側フード部１３で雄コネクタ３０のフード部３３の変形を防ぎ、パッキン１８の圧縮量を確保することで、防水コネクタ１の防水性を常に維持することができる。 Further, as shown in FIGS. 12 to 14, when the fitting detection member 20 is fully locked, the fitting detection member 20 is located between the lock portion 35 of the male housing 31 and the outer hood portion 13 of the female housing 11. Get into it. In addition, the deflection prevention portion 22 of the fitting detection member 20 enters between the outer hood portion 13 and the hood portion 33, and prevents the movement of the hood portion 33 of the male housing 31 from being displaced in the direction of arrow Y due to the repulsive force of the packing 18. It is pressed by the pressing part 22b of the deflection prevention part 22. Moreover, since the pressing part 22b of the deflection prevention part 22 is formed in an L-shape so as to protrude inwardly, the hood part 33 of the male housing 31 can be more securely pressed by the pressing part 22b protruding inwardly. This deformation can be prevented. In this way, the pressing portion 22b of the deflection preventing portion 22 of the fitting detection member 20 and the outer hood portion 13 of the female housing 11 prevent deformation of the hood portion 33 of the male connector 30 and ensure the amount of compression of the packing 18. , the waterproofness of the waterproof connector 1 can be maintained at all times.

以上、本実施形態を説明したが、本実施形態はこれらに限定されるものではなく、本実施形態の要旨の範囲内で種々の変形が可能である。 Although this embodiment has been described above, this embodiment is not limited to these, and various modifications can be made within the scope of the gist of this embodiment.

すなわち、前記実施形態によれば、段落[００２３]に記載の如く、雌雄ハウジング１１，３１の嵌合後において、アーム部２３が雄ハウジング３１のロック部３５で持ち上げられ、嵌合検知部材２０の本係止への移行方向の移動が可能となっているが、嵌合検知部材２０は、雌雄両ハウジング１１，３１同士の嵌合後にスライドさせても、操作部２１を嵌合方向に押圧することでアーム部２３の前端がロック部１５を押圧して雌雄両ハウジング１１，３１同士の嵌合を進め、ロックアーム１６がロック部３５を乗り越えたのに引き続いて嵌合検知部材２０を本係止位置（図１２の状態）に至らせるものでも良い。 That is, according to the embodiment, as described in paragraph [0023], after the male and female housings 11 and 31 are fitted, the arm part 23 is lifted by the locking part 35 of the male housing 31, and the fitting detection member 20 is lifted. Although it is possible to move in the direction of transition to full locking, the fitting detection member 20 does not press the operating part 21 in the fitting direction even if it is slid after the male and female housings 11 and 31 are fitted together. As a result, the front end of the arm portion 23 presses the lock portion 15 to advance the mating of the male and female housings 11 and 31, and after the lock arm 16 has climbed over the lock portion 35, the mating detection member 20 is brought into full engagement. It may be possible to reach the stop position (the state shown in FIG. 12).
