しかしながら、前記従来のレバー式コネクタ１では、図１８に示すように、ハウジング４の可撓アーム部６の係合部６ａにレバー７の係止部７ｂが係止ロックする際に、一度可撓アーム部６が撓んでオーバーストロークが発生するため、係止ロック後、可撓アーム部６が正規の位置に戻ると、係合部６ａと係止部７ｂの双方のロック間にクリアランスが発生する。このクリアランスが振動等によるレバー７のガタ付きを発生させるため、ガタによる騒音が発生したり、端子の接点部に影響を及ぼし、電気的導通に弊害が出るおそれがある。 However, in the conventional lever type connector 1, as shown in FIG. 18, when the locking portion 7b of the lever 7 is locked and locked to the engaging portion 6a of the flexible arm portion 6 of the housing 4, the lever 7 is flexed once. Since the arm portion 6 bends and an overstroke occurs, when the flexible arm portion 6 returns to the normal position after the locking lock, a clearance is generated between the locks of both the engaging portion 6a and the locking portion 7b. .. Since this clearance causes rattling of the lever 7 due to vibration or the like, noise due to rattling may be generated, the contact portion of the terminal may be affected, and electrical continuity may be adversely affected.

そこで、本発明は、前記した課題を解決すべくなされたものであり、コネクタ嵌合後のレバーのガタ付きを抑えることができ、振動等による端子接点部への負荷を軽減して、端子接点部の電気的導通を正常に保たせることができるレバー式コネクタを提供することを目的とする。 Therefore, the present invention has been made to solve the above-mentioned problems, and it is possible to suppress rattling of the lever after fitting the connector, reduce the load on the terminal contact portion due to vibration or the like, and reduce the load on the terminal contact portion. It is an object of the present invention to provide a lever type connector capable of maintaining normal electrical continuity of a portion.

Further, as shown in FIGS. 5 and 14, a cover lock portion 48 locked to the lever lock portion 33 of the lever 30 is provided on the rear side of the electric wire holding portion 47 of the ceiling wall 42. The cover lock portion 48 is arranged at the tip end portion of the lock arm 48a which is integrally formed with the ceiling wall 42 and elastically deformed.

さらに、図１４及び図１５（ａ）に示すように、電線カバー４０の天井壁４２のカバーロック部４８と相対向する位置には、レバー３０のレバーロック部３３をカバーロック部４８に押圧付勢するガタ抑え用舌片部（弾性付勢部）４９を切り欠き形成してある。このガタ抑え用舌片部４９は、レバーロック部３３がカバーロック部４８に係止される際に、レバーロック部３３をカバーロック部４８側に押圧付勢して、レバー３０の操作部３１の回動完了時（コネクタ嵌合後）のレバー３０のガタ付きを防ぐものである。 Further, as shown in FIGS. 14 and 15 (a), the lever lock portion 33 of the lever 30 is pressed against the cover lock portion 48 at a position facing the cover lock portion 48 of the ceiling wall 42 of the electric wire cover 40. A tongue piece portion (elastic urging portion) 49 for suppressing backlash is notched and formed. When the lever lock portion 33 is locked to the cover lock portion 48, the backlash suppressing tongue piece portion 49 presses and urges the lever lock portion 33 toward the cover lock portion 48 to force the lever lock portion 33 toward the cover lock portion 48, and the operation portion 31 of the lever 30 This is to prevent the lever 30 from rattling when the rotation of the lever 30 is completed (after the connector is fitted).

尚、図３〜図５に示すように、雌ハウジング２０の両側面には、レバー３０を電線カバー４０の前側或いは後側の両側からそれぞれ装着できるように、レバー３０の仮係止ロック部３６を仮係止するリブ状の仮係止部２６と、各仮係止部２６との仮係止状態が解除されたレバー３０の仮係止ロック部３６の係止突起３６ｂを収納する凹状のロック収納部２７とを、ボス穴２４を挟むように左右両側に一対形成してある。 As shown in FIGS. 3 to 5, the temporary locking lock portion 36 of the lever 30 can be mounted on both side surfaces of the female housing 20 from both the front side or the rear side of the wire cover 40. A concave shape for accommodating the rib-shaped temporary locking portion 26 for temporarily locking the lever and the locking projection 36b of the temporary locking lock portion 36 of the lever 30 in which the temporary locking portion 26 is released. A pair of lock storage portions 27 are formed on both the left and right sides so as to sandwich the boss holes 24.

また、図１に示すように、雄ハウジング１１に設けられた円柱状のカムボス１３の上端には、楕円鍔状の掛止片部１３ａを突設してある。そして、このカムボス１３の掛止片部１３ａがレバー３０のカム溝３５の一方の円弧部に突設されたガイドリブ３５ｂに掛かって移動することで、カムボス１３がカム溝３５から外れないようになっている。さらに、図１及び図７に示すように、レバー３０のアーム部３２の先端側には、薄肉で円弧状の一対の係合片部３２ａ，３２ａを突設してある。そして、図６に示すように、レバー３０の仮係止ロック解除時に、雄ハウジング１１のカムボス１３の掛止片部１３ａがレバー３０のカム溝３５のガイドリブ３５ｂに掛止され、レバー３０の一対の係合片部３２ａ，３２ａが雌ハウジング２０の外套部２２の両側よりＬ字状に突設した一対の係止片部２２ｂ，２２ｂに係合されることで、雄ハウジング１１及びレバー３０が雌ハウジング２０側から外れないようになっている。 Further, as shown in FIG. 1, an elliptical collar-shaped hook piece portion 13a is projected from the upper end of the columnar cam boss 13 provided in the male housing 11. Then, the hooking piece portion 13a of the cam boss 13 moves by hanging on the guide rib 35b projecting from one arc portion of the cam groove 35 of the lever 30, so that the cam boss 13 does not come off from the cam groove 35. ing. Further, as shown in FIGS. 1 and 7, a pair of thin, arc-shaped engaging piece portions 32a, 32a are projected from the tip end side of the arm portion 32 of the lever 30. Then, as shown in FIG. 6, when the temporary locking lock of the lever 30 is released, the hooking piece portion 13a of the cam boss 13 of the male housing 11 is hooked on the guide rib 35b of the cam groove 35 of the lever 30, and the pair of levers 30 is engaged. The male housing 11 and the lever 30 are engaged by engaging the engaging piece portions 32a and 32a of the female housing 20 with a pair of locking piece portions 22b and 22b projecting from both sides of the mantle portion 22 of the female housing 20 in an L shape. It is designed so that it does not come off from the female housing 20 side.

以上実施形態のレバー式コネクタ１０によれば、雌コネクタＢを組み付ける場合には、まず、図３に示すように、雌ハウジング２０のハウジング本体２１の端子収容室２１ａに電線５１を接続した雌端子５０を挿入する（端子挿入工程）。この際、雌ハウジング２０にレバー３０が組付いていない状態のため、端子挿入の作業性が良い。 According to the lever type connector 10 of the above embodiment, when assembling the female connector B, first, as shown in FIG. 3, a female terminal in which the electric wire 51 is connected to the terminal accommodating chamber 21a of the housing body 21 of the female housing 20. 50 is inserted (terminal insertion step). At this time, since the lever 30 is not attached to the female housing 20, the workability of terminal insertion is good.

次に、図４に示すように、端子収容室２１ａに雌端子５０が挿入された雌ハウジング２０に電線カバー４０を組付ける（カバー組付工程）。この際、雌ハウジング２０にレバー３０が組付いていない状態のため、カバー組付け作業性が良い。 Next, as shown in FIG. 4, the electric wire cover 40 is assembled to the female housing 20 in which the female terminal 50 is inserted into the terminal accommodating chamber 21a (cover assembly step). At this time, since the lever 30 is not attached to the female housing 20, the cover assembly workability is good.

次に、図５と図６に示すように、雌ハウジング２０のボス穴２４にレバー３０のレバーボス３４を嵌め込んで、雌ハウジング２０にレバー３０を組付ける（レバー組付工程）。この際、電線カバー４０の側壁４１に設けられた一対のガイドリブ４６，４６間にレバー３０のレバーボス３４が案内され、レバーボス３４が雌ハウジング２０に形成された突起物等に当たることなくボス穴２４に誘い込まれるため、レバー３０の組付け性が向上する。そして、図１及び図６に示す組付け状態の雌コネクタＢと図１に示す雄ハウジング１１等からなる雄コネクタＡは、嵌合しない分離した状態で車両組付工場等へ出荷される。 Next, as shown in FIGS. 5 and 6, the lever boss 34 of the lever 30 is fitted into the boss hole 24 of the female housing 20, and the lever 30 is assembled to the female housing 20 (lever assembly step). At this time, the lever boss 34 of the lever 30 is guided between the pair of guide ribs 46, 46 provided on the side wall 41 of the electric wire cover 40, and the lever boss 34 does not hit the protrusion or the like formed on the female housing 20 and enters the boss hole 24. Since it is attracted, the assembling property of the lever 30 is improved. Then, the male connector A including the female connector B in the assembled state shown in FIGS. 1 and 6 and the male housing 11 and the like shown in FIG. 1 is shipped to the vehicle assembly factory and the like in a separated state without fitting.

また、図１及び図８に示すように、レバー式コネクタ１０の雄ハウジング１１と雌ハウジング２０の嵌合前の状態では、雌ハウジング２０のリブ状の仮係止部２６にレバー３０の仮係止ロック部３６の係止突起３６ｂが仮係止されている。この状態から、図６に示すように、雄ハウジング１１のフード部１２を雌ハウジング２０のハウジング本体２１と外套部２２との間に嵌め込むと、図７及び図９に示すように、雄ハウジング１１のレバー仮係止解除リブ１４の先端１４ａ側がレバー３０の仮係止ロック部３６の係止突起３６ｂが突き当たって、仮係止ロック部３６のロックアーム３６ａが外側に撓むことで、レバー３０の仮係止ロック部３６の係止突起３６ｂと雌ハウジング２０のリブ状の仮係止部２６との仮係止状態が解除される。 Further, as shown in FIGS. 1 and 8, in the state before the male housing 11 and the female housing 20 of the lever type connector 10 are fitted, the lever 30 is temporarily engaged with the rib-shaped temporary locking portion 26 of the female housing 20. The locking projection 36b of the stop lock portion 36 is temporarily locked. From this state, as shown in FIG. 6, when the hood portion 12 of the male housing 11 is fitted between the housing main body 21 and the mantle portion 22 of the female housing 20, the male housing is as shown in FIGS. 7 and 9. The tip 14a side of the lever temporary locking release rib 14 of 11 abuts the locking projection 36b of the temporary locking lock portion 36 of the lever 30, and the lock arm 36a of the temporary locking lock portion 36 bends outward to cause the lever. The temporary locking state of the locking projection 36b of the temporary locking lock portion 36 of 30 and the rib-shaped temporary locking portion 26 of the female housing 20 is released.

そして、図１０に示すように、慣性の力で雄ハウジング１１のフード部１２が雌ハウジング２０のハウジング本体２１と外套部２２との間の奥に更に押し込まれると、図１１に示すように、レバー３０の仮係止ロック部３６の係止突起３６ｂが雌ハウジング２０のロック収納部２７に落ち込む。よって、レバー３０は、復動操作方向（図１０に示す往動操作方向Ｔとは逆方向）には動かない状態になっている。その際、図１０に示すように、雄ハウジング１１のカムボス１３の掛止片部１３ａがレバー３０のカム溝３５のガイドリブ３５ｂに掛かっていて該カム溝３５からも外れることがないため、レバー３０のカム溝３５が雄ハウジング１１のカムボス１３から抜けることがなく、カムボス１３のカム溝３５に対する引き込みも容易にできる。このように、レバー３０の仮係止解除と雄ハウジング１１の脱落防止を同時にでき、しかもレバー３０が雄ハウジング１１から抜けることなく、レバー嵌合作業が可能となる。 Then, as shown in FIG. 10, when the hood portion 12 of the male housing 11 is further pushed into the depth between the housing body 21 and the mantle portion 22 of the female housing 20 by the force of inertia, as shown in FIG. The locking projection 36b of the temporary locking lock portion 36 of the lever 30 falls into the lock storage portion 27 of the female housing 20. Therefore, the lever 30 is in a state of not moving in the reverse operation direction (the direction opposite to the forward operation direction T shown in FIG. 10). At that time, as shown in FIG. 10, since the hook piece portion 13a of the cam boss 13 of the male housing 11 is hooked on the guide rib 35b of the cam groove 35 of the lever 30 and does not come off from the cam groove 35, the lever 30 The cam groove 35 does not come off from the cam boss 13 of the male housing 11, and the cam boss 13 can be easily pulled into the cam groove 35. In this way, the temporary locking of the lever 30 and the prevention of the male housing 11 from falling off can be prevented at the same time, and the lever fitting work can be performed without the lever 30 coming off the male housing 11.

また、レバー３０のレバーロック部３３と電線カバー４０のカバーロック部４８が完全に係止する前の段階で、レバーロック部３３に押され、ガタ抑え用舌片部４９は撓み始める。そして、図１５（ａ）に示すように、レバーロック部３３とカバーロック部４８が完全に係止した後、ガタ抑え用舌片部４９は撓んだ状態でレバーロック部３３に接している状態であるため、ガタ抑え用舌片部４９には反力が発生し、レバーロック部３３を図中矢印Ｒの方向にレバーロック部３３を押す荷重が常時掛かった状態を保つことができる。即ち、図１５（ｂ）に示す参考例のように、ガタ抑え用舌片部４９が設けられていない場合、レバーロック部３３とカバーロック部４８との間にクリアランスＨが発生するが、本実施形態では、レバーロック部３３とカバーロック部４８の完全係止状態では、レバーロック部３３はガタ抑え用舌片部４９の押圧付勢力によりカバーロック部４８側に常に押圧されていて、クリアランスＨが発生することがないため、コネクタ嵌合後のレバー３０のガタ付きやガタ付きによる騒音を確実に抑えることができ、振動等による雄雌両端子の接点部への負荷を軽減して、端子接点部の電気的導通を常に正常に保たせることができる。 Further, before the lever lock portion 33 of the lever 30 and the cover lock portion 48 of the electric wire cover 40 are completely locked, the lever lock portion 33 pushes the lever lock portion 33 and the tongue piece portion 49 for suppressing backlash begins to bend. Then, as shown in FIG. 15A, after the lever lock portion 33 and the cover lock portion 48 are completely locked, the backlash suppressing tongue piece portion 49 is in contact with the lever lock portion 33 in a bent state. Since this is the state, a reaction force is generated on the backlash suppressing tongue piece portion 49, and the load for pushing the lever lock portion 33 in the direction of the arrow R in the drawing can be maintained at all times. That is, as in the reference example shown in FIG. 15B, when the tongue piece portion 49 for suppressing backlash is not provided, a clearance H is generated between the lever lock portion 33 and the cover lock portion 48. In the embodiment, in the completely locked state of the lever lock portion 33 and the cover lock portion 48, the lever lock portion 33 is always pressed toward the cover lock portion 48 by the pressing force of the tongue piece portion 49 for suppressing backlash, and the clearance Since H does not occur, the rattling and rattling of the lever 30 after fitting the connector can be reliably suppressed, and the load on the contact points of both male and female terminals due to vibration etc. can be reduced. The electrical continuity of the terminal contact portion can always be maintained normally.

尚、前記実施形態によれば、レバーを電線カバーの前側から雌ハウジングに装着するようにしたが、レバーを電線カバーの後側から雌ハウジングに装着するようにしても良い。 According to the above embodiment, the lever is attached to the female housing from the front side of the electric wire cover, but the lever may be attached to the female housing from the rear side of the electric wire cover.
