Is moved forward (rotated in the direction indicated by arrow T in FIG. 18), the cover pushing projections 89 provided on the pair of arm portions 82, 82 of the lever 80 and the side walls 71 of the wire cover 70, When the abutment protrusion 79 provided on 71 abuts and the lever 80 continues to be rotated, the wire cover 70 is pushed to the normal locking position, and the elastic lock piece 75 of the wire cover 70 is moved to the female housing 21. It is latched by the recessed locked part 25. As a result, the wire cover 70 can be moved to a normal position and locked by the cover pushing protrusion 89 of the elastic lock piece 75 without the wire cover 70 being locked to the female housing 21. .
そして、図19に示すように、雄、雌両コネクタ11,20の嵌合完了位置(レバー80の往動操作完了位置)までレバー80を回動させると、一対のアーム部82,82の各弾性ロック片88のロックアーム部88aが弾性変形し、各カバー押込み突起89が電線カバー70の両側壁71,71の各突き当て突起79を乗り越え、電線カバー70を挟み込むように当接し続けた状態になる。この際、斜面89bによりカバー押込み突起89は突き当て突起79を乗り越え易くなっている。また、弾性ロック片88のロックアーム部88aの反力>突き当て突起79の反力の関係となっている(その差が10N以上が望ましい)。このように、レバー80の一対のアーム部82,82に設けられた各弾性ロック片88のロックアーム部88aが弾性変形し、一対のアーム部82,82で電線カバー70の両側壁71,71を挟み込む状態で維持されるため、レバー80及び電線カバー70のガタ付きを確実に防止することができる。 Then, as shown in FIG. 19, when the lever 80 is rotated to the fitting completion position of the male and female connectors 11, 20 (the forward movement completion position of the lever 80), each of the pair of arm portions 82, 82 is provided. The lock arm portion 88a of the elastic lock piece 88 is elastically deformed, and the respective cover pushing projections 89 get over the respective abutment projections 79 of the side walls 71 and 71 of the electric wire cover 70 and continue to abut so as to sandwich the electric wire cover 70. become. At this time, the cover pressing projection 89 is easy to get over the butting projection 79 by the inclined surface 89b. Further, the reaction force of the lock arm 88a of the elastic lock piece 88 is greater than the reaction force of the abutting projection 79 (the difference is preferably 10 N or more). In this manner, the lock arm portions 88a of the elastic lock pieces 88 provided on the pair of arm portions 82 and 82 of the lever 80 are elastically deformed, and the pair of arm portions 82 and 82 cause both side walls 71 and 71 of the wire cover 70 to be elastically deformed. Therefore, rattling of the lever 80 and the wire cover 70 can be reliably prevented.
さらに、レバー80を回動させ、レバー80の操作部81の下面側の係止突起83を電線カバー70の天井壁72の中央のロック突起78へ係止させ、雄、雌両コネクタ11,20を嵌合させる際、図14及び図15に示すように、電線カバー70のロック突起78とレバー80の係止突起83が係止完了となる前に、レバー80の係止突起83の両側に設けられた一対の弾性変形部85,85と電線カバー70のロック突起78の両側の一対の保護壁77,77が当接する。 Further, the lever 80 is rotated so that the locking protrusion 83 on the lower surface side of the operation portion 81 of the lever 80 is locked to the locking protrusion 78 at the center of the ceiling wall 72 of the electric wire cover 70, and both the male and female connectors 11, 20 are engaged. 14 and 15, before the locking projections 78 of the wire cover 70 and the locking projections 83 of the lever 80 are completely locked, as shown in FIGS. The pair of provided elastic deformation portions 85 and 85 and the pair of protective walls 77 and 77 on both sides of the lock projection 78 of the electric wire cover 70 abut.
図16及び図17に示すように、レバー80の弾性変形部85と電線カバー70の保護壁77が当接した後も、レバー80を雄、雌両コネクタ11,20の嵌合完了方向へ回動操作すると、レバー80の弾性変形部85の薄肉部85bが弾性変形し、ロック係止位置までレバー80を回動させることが可能となる。レバー80の係止後は、弾性変形した弾性変形部85の薄肉部85bの反力により、レバー80のガタ付きを確実に抑制することができる。このように、レバー80の弾性変形部85の薄肉部85bに発生している反力により、レバー80のガタ付きを簡単かつ確実に抑制することができる。これにより、レバー80の一対のアーム部82,82と電線カバー70の一対の側壁71,71間のクリアランス(オーバーストローク)を最小限に設定することができ、その分、コネクタ全体の小型化を図ることができる。 As shown in FIGS. 16 and 17, even after the elastic deformation portion 85 of the lever 80 and the protective wall 77 of the wire cover 70 contact each other, the lever 80 is rotated in the direction in which the male and female connectors 11 and 20 are fitted. When the moving operation is performed, the thin portion 85b of the elastic deformation portion 85 of the lever 80 is elastically deformed, and the lever 80 can be rotated to the lock engagement position. After the lever 80 is locked, the backlash of the lever 80 can be reliably suppressed by the reaction force of the thin portion 85b of the elastically deformable portion 85 that has been elastically deformed. As described above, rattling of the lever 80 can be easily and reliably suppressed by the reaction force generated in the thin portion 85 b of the elastically deforming portion 85 of the lever 80. As a result, the clearance (overstroke) between the pair of arm portions 82 and 82 of the lever 80 and the pair of side walls 71 and 71 of the wire cover 70 can be set to a minimum, thereby reducing the overall size of the connector. I can plan.
