嵌合検知部４０は、弾性変形する矩形板状（アーム状）に設けられている。この矩形板状の嵌合検知部４０の先端４０ａには、雌雄両ハウジング２１，５１の嵌合時に後述する雄ハウジング５１の上側の係止突起５３を乗り越えて雌ハウジング２１の上側の係止孔２４の係止片（係止部）２４ａに係合される係合突起（係合部）４１を一体突出形成してある。 The fitting detection unit 40 is provided in a rectangular plate shape (arm shape) that is elastically deformed. The front end 40a of the rectangular plate-shaped fitting detection unit 40 is moved over a locking projection 53 on the upper side of the male housing 51, which will be described later, when the male and female housings 21 and 51 are fitted, and a locking hole on the upper side of the female housing 21. Engaging protrusions (engaging portions) 41 that are engaged with 24 locking pieces (locking portions) 24a are integrally projected.

また、矩形板状の嵌合検知部４０の後端４０ｂ側に、電線カバー３０の雌ハウジング２１の本係止への操作方向及び本係止からの解除方向に押圧可能な操作部４２を一体突出形成してある。 Further, an operation portion 42 that can be pressed in the operation direction to the main locking of the female housing 21 of the female housing 21 and the release direction from the main locking is integrated with the rear end 40b side of the rectangular plate-shaped fitting detection portion 40. Protrusions are formed.

図１、図３〜図５に示すように、雄コネクタ５０は、前側に筒状のフード部５２を一体突出形成した合成樹脂製の雄ハウジング５１と、このフード部５２内に露出された複数の雄端子５４とを備えている。また、フード部５２の上下壁５２ａ，５２ｂの前端側には、上下一対の係止突起（被係止部）５３，５３を一体突出形成してある。 As shown in FIGS. 1 and 3 to 5, the male connector 50 includes a male housing 51 made of a synthetic resin in which a cylindrical hood portion 52 is integrally formed on the front side, and a plurality of exposed male hood portions 52. The male terminal 54 is provided. Further, a pair of upper and lower locking projections (locked portions) 53 and 53 are integrally formed on the front end sides of the upper and lower walls 52 a and 52 b of the hood portion 52.

次に、以上実施形態のコネクタ１０の電線カバー３０の仮係止状態から本係止状態（正規嵌合状態）までを、図２〜図６を用いて順に説明する。 Next, from the temporarily locked state of the wire cover 30 of the connector 10 of the embodiment to the fully locked state (normally fitted state) will be described in order with reference to FIGS.

まず、図２に示すように、雌コネクタ２０の雌ハウジング２１に電線カバー３０を装着し、雌ハウジング２１の一対のロック突起２２，２２を電線カバー３０の一対の仮係止凹部３４，３４に係止して仮係止状態にする。この時、電線カバー３０に一体突出形成された嵌合検知部４０の先端４０ａの係合突起４１が雌ハウジング２１の係止孔２４の係止片２４ａに当接するまで電線カバー３０を雌ハウジング２１に対して挿入する。 First, as shown in FIG. 2, the electric wire cover 30 is attached to the female housing 21 of the female connector 20, and the pair of lock protrusions 22, 22 of the female housing 21 are formed in the pair of temporary locking recesses 34, 34 of the electric wire cover 30. Lock to a temporary locked state. At this time, the electric wire cover 30 is moved to the female housing 21 until the engaging protrusion 41 of the end 40a of the fitting detecting portion 40 formed integrally with the electric wire cover 30 contacts the locking piece 24a of the locking hole 24 of the female housing 21. Insert against.

この嵌合検知部４０の先端４０ａの係合突起４１が雌ハウジング２１の係止孔２４の係止片２４ａに当接しているため、それ以上電線カバー３０は動かず、この仮係止状態では、雌コネクタ２０と雄コネクタ５０の嵌合が発生していない。 Since the engagement protrusion 41 of the tip 40a of the fitting detection part 40 is in contact with the locking piece 24a of the locking hole 24 of the female housing 21, the wire cover 30 does not move any more, and in this temporarily locked state The female connector 20 and the male connector 50 are not fitted.

また、電線カバー３０のロック突起３６の本係止用の雌ハウジング２１のロック突起２５が見えている状態になっているため、そこでも仮係止状態であることが判別できる。 Moreover, since the lock protrusion 25 of the female housing 21 for main locking of the lock protrusion 36 of the electric wire cover 30 is visible, it can be determined that the temporary locking state is also present there.

そして、図３に示すように、上記の仮係止状態にて、雄コネクタ５０の雄ハウジング５１と雌コネクタ２０の雌ハウジング２１の嵌合作業を開始させる。 Then, as shown in FIG. 3, the mating operation of the male housing 51 of the male connector 50 and the female housing 21 of the female connector 20 is started in the temporary locking state.

図４に示すように、雄コネクタ５０の雄ハウジング５１と雌コネクタ２０の雌ハウジング２１の嵌合後、嵌合検知部４０の先端４０ａの係合突起４１が雄ハウジング５１の上側の係止突起５３に乗り上げることにより、電線カバー３０の本係止に移行できるようになる。 As shown in FIG. 4, after the male housing 51 of the male connector 50 and the female housing 21 of the female connector 20 are fitted, the engaging protrusion 41 of the tip 40 a of the fitting detecting portion 40 is the locking protrusion on the upper side of the male housing 51. By getting on 53, it becomes possible to shift to the main locking of the wire cover 30.

次に、図５に示すように、雄ハウジング５１の上下一対の係止突起５３，５３が雌ハウジング２１の上下一対の係止孔２４，２４に係止して、嵌合検知部４０の先端４０ａの係合突起４１が雄ハウジング５１の上側の係止突起５３を乗り越えると、嵌合検知部４０の先端４０ａの係合突起４１が雌ハウジング２１の係止孔２４の係止片２４ａの外側に係止（本係止）され、電線カバー３０のロック突起３６も雌ハウジング２１のロック突起２５に係止されて本係止状態になるため、雄コネクタ５０の雄ハウジング５１と雌コネクタ２０の雌ハウジング２１が正規の嵌合状態になったことが確認できる。この際、図６に示すように、雌ハウジング２１の一対のロック突起２２，２２が電線カバー３０の一対の本係止凹部３５，３５に係止（本係止）される。 Next, as shown in FIG. 5, the pair of upper and lower locking projections 53, 53 of the male housing 51 are locked to the pair of upper and lower locking holes 24, 24 of the female housing 21, and When the engaging protrusion 41 of 40 a gets over the engaging protrusion 53 on the upper side of the male housing 51, the engaging protrusion 41 of the tip 40 a of the fitting detection unit 40 is outside the engaging piece 24 a of the engaging hole 24 of the female housing 21. Since the lock projection 36 of the electric wire cover 30 is also locked by the lock projection 25 of the female housing 21 and is in the final lock state, the male housing 51 of the male connector 50 and the female connector 20 are It can be confirmed that the female housing 21 has been properly fitted. At this time, as shown in FIG. 6, the pair of lock protrusions 22, 22 of the female housing 21 are locked (finally locked) to the pair of main locking recesses 35, 35 of the wire cover 30.

このように、電線２９を保護する電線カバー３０とコネクタ嵌合を検知して保証する嵌合検知部４０を一体化することにより、部品点数を減らし、コネクタ嵌合保証と電線保護を同時に行うことができる。 Thus, by integrating the wire cover 30 that protects the wire 29 and the fitting detection unit 40 that detects and guarantees connector fitting, the number of parts can be reduced, and connector fitting guarantee and wire protection can be performed simultaneously. Can do.

また、電線カバー３０の雌ハウジング２１の本係止への操作方向と雌雄両ハウジング２１，５１の嵌合方向とが同一方向になるようにしたことにより、コネクタ嵌合及び嵌合検知部４０付きの電線カバー３０の本係止をワンアクションで簡単かつ確実に行うことができる。 In addition, since the operation direction of the wire cover 30 to the main locking of the female housing 21 and the fitting direction of both the male and female housings 21 and 51 are the same direction, the connector fitting and fitting detecting unit 40 is provided. It is possible to easily and reliably perform the main locking of the electric wire cover 30 with one action.

さらに、矩形板状の嵌合検知部４０の後端４０ｂ側に、電線カバー３０の雌ハウジング２１の本係止への操作方向及び本係止からの解除方向に押圧可能な操作部４２を設けたことにより、電線カバー３０の仮係止と本係止間の移動操作を簡単かつスムーズに行うことができる。 Furthermore, the operation part 42 which can be pressed in the operation | movement direction to the main latch of the female housing 21 of the electric wire cover 30 and the release direction from this latch is provided in the rear end 40b side of the rectangular-plate-shaped fitting detection part 40. Thus, the movement operation between the temporary locking and the main locking of the wire cover 30 can be performed easily and smoothly.

さらに、電線カバー３０に雌ハウジング２１のレール部２３が案内される凹溝状のガイド部３７を設けたことにより、電線カバー３０の仮係止から本係止までの移動をスムーズに行うことができる。 Furthermore, by providing the wire cover 30 with the groove-shaped guide portion 37 for guiding the rail portion 23 of the female housing 21, the wire cover 30 can be smoothly moved from the temporary lock to the final lock. it can.

尚、前記実施形態によれば、嵌合検知部付きの電線カバーを雌ハウジングに組み付ける（仮係止させる）方向が嵌合検知部付きの電線カバーを雌ハウジングに本係止する操作方向と同一方向になるようにしたが、同一方向でなくとも良い。 According to the embodiment, the direction in which the electric wire cover with the fitting detection portion is assembled (temporarily locked) to the female housing is the same as the operation direction in which the electric wire cover with the fitting detection portion is permanently locked to the female housing. Although it is set to be in the direction, it does not have to be the same direction.
