＜請求項１の発明＞
一般に、レバー式コネクタでは、カムピンがカム溝に係合した状態でレバーを回動すると、これらの間に作用する嵌合力（両コネクタハウジングを嵌合させる方向に作用する力）を通じてコネクタハウジング同士の嵌合がなされる。しかし、請求項１の発明のように、カム板がコネクタハウジングの一面にのみ配されているものでは、上記した嵌合力が両コネクタハウジング間でバランスしにくい。つまり、カム板が設けられた側が先行して相手コネクタハウジングに嵌合し、逆に、カム板が設けられていない反対側では嵌合が遅れるため、両コネクタハウジングは高さ方向の中心軸で傾斜した姿勢で嵌合するおそれがある。また、カムピンとカム溝との係合が、両コネクタハウジングの幅方向に関して偏位していれば、両コネクタハウジングは幅方向の中心軸から傾斜した姿勢で嵌合してしまうおそれがある。
その点、請求項１の発明では、カム溝とカムピンとの係合箇所に加え、嵌合完了の際には少なくとも他の一箇所の係合箇所を設け、両コネクタハウジングの幅方向あるいは高さ方向で嵌合力がバランスするようにしたため、両コネクタハウジングを真っ直ぐな嵌合姿勢に矯正させることができる。 <Invention of Claim 1>
In general, in a lever-type connector, when the lever is rotated with the cam pin engaged with the cam groove, the connector housings are connected to each other through a fitting force acting between them (a force acting in a direction in which both the connector housings are fitted). A mating is made. However, when the cam plate is disposed only on one surface of the connector housing as in the first aspect of the invention, the above-mentioned fitting force is difficult to balance between the two connector housings. In other words, the side on which the cam plate is provided is first fitted into the mating connector housing, and conversely, the fitting is delayed on the opposite side where the cam plate is not provided, so both connector housings are centered in the height direction. There is a risk of mating in an inclined posture. Further, if the engagement between the cam pin and the cam groove is deviated with respect to the width direction of the two connector housings, the two connector housings may be fitted in a posture inclined from the central axis in the width direction.
In that respect, in the invention of claim 1, in addition to the engagement portion between the cam groove and the cam pin, at the time of completion of the engagement, at least one other engagement portion is provided, and the width direction or height of both connector housings is provided. Since the fitting force is balanced in the direction, both connector housings can be corrected to a straight fitting posture.

また、カム板が設けられた側で両コネクタハウジングの嵌合が先行しても、両コネクタハウジングの嵌合が完了する際には、カムピンとカム溝との係合箇所と両コネクタハウジングの高さ方向に関する中心軸を挟んだ対称位置において、姿勢矯正アームの引っ掛け部と受け部との係合によって両コネクタハウジングを嵌合させる方向の力が生じるため、両コネクタハウジングの高さ方向の中心軸を挟んだ両側で嵌合力がバランスし、その結果、嵌合が遅れていた側での嵌合が進み、両コネクタハウジングが真っ直ぐな嵌合姿勢に矯正される。 In addition, even if the two connector housings are preliminarily fitted on the side where the cam plate is provided, when the fitting of the two connector housings is completed, the engagement location between the cam pin and the cam groove and the height of the two connector housings are not sufficient. At the symmetrical position across the central axis with respect to the vertical direction, the force in the direction of fitting both the connector housings is generated by the engagement of the hook portion of the posture correcting arm and the receiving portion, so the central axis in the height direction of both connector housings As a result, the mating force is balanced on both sides of the gap, and as a result, the mating on the side where the mating is delayed proceeds, and both connector housings are corrected to a straight mating posture.

＜請求項２の発明＞
請求項２の発明によれば、カムピンとカム溝との係合箇所が両コネクタハウジングの幅方向に関する中心軸から一方へ偏位しているため、この係合側でレバーが設けられているコネクタハウジングは相手側コネクタハウジングに対して先行して嵌合がなされることがある。しかし、嵌合が完了する際には、カムピンによる係合箇所とは幅方向の反対側で、レバーの操作アームの押し面がコネクタハウジングを押して相手側コネクタハウジングを押し入れるため、両コネクタハウジングが真っ直ぐな嵌合姿勢に矯正される。 <Invention of Claim 2 >
According to the second aspect of the present invention, since the engaging portion between the cam pin and the cam groove is deviated from the central axis in the width direction of the two connector housings to one side, the connector provided with the lever on this engaging side The housing may be pre-fitted to the mating connector housing. However, when the mating is completed, since the pushing surface of the lever operation arm pushes the connector housing and pushes the mating connector housing on the side opposite to the width of the cam pin, the two connector housings It is corrected to a straight fitting position.

＜請求項３の発明＞
カムピンとカム溝との係合箇所が両コネクタハウジングの幅方向に関する中心軸から一方へ偏位しているため、この係合側でレバーが設けられているコネクタハウジングは相手側コネクタハウジングに対して先行して嵌合がなされるおそれがあるが、請求項４の発明によれば、上記係合箇所とは幅方向の反対側でロック突部がガイド溝による案内を受けるため、コネクタハウジングの嵌合姿勢は正規姿勢に保持され、嵌合完了した時点で、係止片が相手側コネクタハウジングのロック突部と係止して両コネクタハウジングの嵌合状態がロックされる。 <Invention of Claim 3 >
Since the engaging portion of the cam pin and the cam groove is deviated from the central axis in the width direction of both connector housings to one side, the connector housing provided with the lever on this engaging side is opposite to the mating connector housing. According to the invention of claim 4, since the lock projection is guided by the guide groove on the side opposite to the engagement portion in the width direction, the connector housing is fitted. The alignment posture is held in a normal posture, and when the fitting is completed, the locking piece is locked with the locking protrusion of the mating connector housing, and the fitting state of both connector housings is locked.

A cam plate engaging portion 26 projects from the lever mounting surface 23 along with the support shaft 25, and this cam plate engaging portion 26 engages with an engaging recess 47 B formed in the cam plate 47. At the same time, the lever 40 is retained at the initial mating position and the final mating position.

ハウジング本体１１の下面には、支軸２５と上下方向に関して同軸上の位置に、レバー４０に設けられた姿勢矯正アーム４６の軸受部４６Ａを嵌め込むことにより、支軸２５とともにレバー４０を両持ち状となす支持軸２７が突設されている。支持軸２７の先端には、相互に反対方向に突出する抜け止め突部２７Ａが形成されており、レバー４０の回動途中において姿勢矯正アーム４６が支持軸２７から抜け出ないようにしてある。また、ハウジング本体１１の下面には、前後方向に関して支持軸２７とリテーナ装着孔１７を挟んだ反対側でかつ幅方向両端部に、左右一対の調整突部２８が形成されている。両調整突部２８は、支持軸２７とほぼ同じ突出寸法を有してその先端位置を支持軸２７の先端位置とほぼ同じ位置に揃えており、両コネクタハウジング１０，８０の嵌合過程で雌側のコネクタハウジング１０が前のめりになって嵌合するのを防止する役割を担っている。 The bearing body 46A of the posture correcting arm 46 provided on the lever 40 is fitted on the lower surface of the housing main body 11 at a position coaxial with the support shaft 25 in the vertical direction, so that both the lever 40 and the support shaft 25 are supported. A support shaft 27 is formed in a protruding manner. At the tip of the support shaft 27, a retaining protrusion 27A that protrudes in opposite directions is formed so that the posture correcting arm 46 does not come out of the support shaft 27 while the lever 40 is rotating. In addition, a pair of left and right adjustment protrusions 28 are formed on the lower surface of the housing body 11 on the opposite side of the support shaft 27 and the retainer mounting hole 17 with respect to the front-rear direction and at both ends in the width direction. Both adjustment protrusions 28 have substantially the same projecting dimensions as the support shaft 27, and their tip positions are aligned with the same position as the tip position of the support shaft 27. It plays the role which prevents the connector housing 10 on the side from being fitted forward.

覆い壁２２には、図２５に示すように、前後方向に関して支軸２５の直前方位置に、雄側のコネクタハウジング８０のカムピン８８が導入されるカムピン導入溝２２Ａが、前後方向に延びるとともに前端に開口して形成されている。また、覆い壁２２には、カムピン導入溝２２Ａとは反対側へ偏位した位置に、雄側のコネクタハウジング８０のロック突部８９を導入するためのガイド溝２２Ｂが、同じく前後方向に延びるとともに前端に開口して形成されている。カムピン８８はカムピン導入溝２２Ａの両側縁に摺接可能に導入されるとともに、ロック突部８９がガイド溝２２Ｂの両側縁に摺接可能に導入されるようになっている。さらに、覆い壁２２には、雄側のコネクタハウジング８０の解除突部９２を摺接状態で導入するための案内溝２２Ｅが、ガイド溝２２Ｂとは反対側でかつこのガイド溝２２Ｂ及びカムピン導入溝２２Ａと平行に配されている。 As shown in FIG. 25, the cover wall 22 has a cam pin introduction groove 22A into which the cam pin 88 of the male connector housing 80 is introduced at a position immediately before the support shaft 25 in the front-rear direction. It is formed to open. Further, a guide groove 22B for introducing the locking projection 89 of the male connector housing 80 at a position displaced to the opposite side to the cam pin introduction groove 22A extends in the front-rear direction in the cover wall 22 as well. An opening is formed at the front end. The cam pins 88 are slidably introduced into both side edges of the cam pin introduction groove 22A, and the lock projections 89 are slidably introduced into both side edges of the guide groove 22B. Further, the cover wall 22 has a guide groove 22E for introducing the release protrusion 92 of the male connector housing 80 in a sliding contact state on the side opposite to the guide groove 22B and the guide groove 22B and the cam pin introduction groove. It is arranged in parallel with 22A.

ハウジング本体１１における収容空間２１の一側（図示する左側）は、レバー装着面２３及び覆い壁２２の一部を切り欠いて後面に開口しており、ここがレバー４０に設けられた方形枠状の保護部４８を収容可能な保護部収容空間２１Ａとして構成されている。また、ハウジング本体１１の一側面には、図１３に示すように、上下方向に延びるとともに上方で収容空間２１に臨むようになっている段付部２９が形成されており、この段付部２９を境とした前方領域が後方領域よりも一段低くなった段差凹部２９Ｂとして構成されている。そして、段付部２９のうち前方を向く段差面は、レバー４０が嵌合完了位置まで回動されたときに、レバー４０に設けられた操作アーム４９に押し当てられる当て面２９Ａとして構成されている。 One side (left side in the figure) of the housing space 21 in the housing body 11 is formed by cutting out a part of the lever mounting surface 23 and the cover wall 22 and opening the rear surface. This is a rectangular frame shape provided on the lever 40. It is comprised as 21 A of protection part accommodation spaces which can accommodate the protection part 48 of this. Further, as shown in FIG. 13, a stepped portion 29 is formed on one side surface of the housing body 11 so as to extend in the vertical direction and to face the accommodation space 21 at the top. The front region with the boundary as a step is configured as a step recess 29B that is one step lower than the rear region. The step surface facing forward in the stepped portion 29 is configured as a contact surface 29A that is pressed against the operation arm 49 provided on the lever 40 when the lever 40 is rotated to the fitting completion position. Yes.

レバー４０は、図１８に示すように、カム板４７と姿勢矯正アーム４６とこれらの端部同士を連結する操作アーム４９とからなり、全体として門型をなしている。カム板４７には、図７に示すように、このカム板４７のうち操作アーム４９から離れた端部側に、雄側のコネクタハウジング８０のカムピン８８と係合可能なカム溝４１が所定方向に延出して形成されており、カムピン８８がカム溝４１に沿って相対的に移動することにより、両コネクタハウジング１０，８０の嵌合離脱操作が可能となっている。なお、かかるカム溝４１は姿勢矯正アーム４６には設けられていない。また、以下のレバー４０の構造説明において前後方向については、レバー４０が嵌合完了位置にある状態（図１０に示す状態）を基準とする。 As shown in FIG. 18, the lever 40 includes a cam plate 47, a posture correction arm 46, and an operation arm 49 that connects these end portions, and has a portal shape as a whole. In the cam plate 47, as shown in FIG. 7, a cam groove 41 that can be engaged with the cam pin 88 of the male connector housing 80 is formed in a predetermined direction on an end portion of the cam plate 47 away from the operation arm 49. When the cam pins 88 are relatively moved along the cam grooves 41, the connector housings 10 and 80 can be engaged and disengaged. The cam groove 41 is not provided in the posture correction arm 46. In the following description of the structure of the lever 40, the front-rear direction is based on the state in which the lever 40 is in the fitting completion position (the state shown in FIG. 10).

カム板４７の内面（下面）のうちカム溝４１の終端の近傍位置には、略円形の軸受部４７Ａが凹設されている。軸受部４７Ａの近傍位置には、この軸受部４７Ａと同心の円弧をなす係合凹部４７Ｂが形成されており、この係合凹部４７Ｂにカム板係合部２６が摺接してレバー４０の回動操作が案内されるようになっている。 A substantially circular bearing portion 47 A is recessed in the inner surface (lower surface) of the cam plate 47 near the end of the cam groove 41. An engaging recess 47B having an arc concentric with the bearing 47A is formed in the vicinity of the bearing 47A. The cam plate engaging portion 26 is slidably contacted with the engaging recess 47B and the lever 40 is rotated. The operation is guided.

カム板４７の外周縁のうちカム溝４１の入り口の近傍位置には、レバー４０が嵌合完了位置にあるときに前後方向に延びる撓み変形可能な仮保持アーム５１が形成されている。仮保持アーム５１は、両コネクタハウジング１０，８０の嵌合前は、その先端突起５１Ａがハウジング本体１１の収容空間２１の側縁部に設けられた仮保持受け部３１と引っ掛け状態で係止してレバー４０の回動操作を規制しており、両コネクタハウジング１０，８０の嵌合動作が開始されることにより、その先端突起５１Ａが雄側のコネクタハウジング８０の解除突部９２に押されて係止解除方向に撓み変形させられて、レバー４０の回動操作を許容するようになっている。 A temporary holding arm 51 that can be bent and deformed in the front-rear direction when the lever 40 is in the fitting completion position is formed in the vicinity of the entrance of the cam groove 41 in the outer peripheral edge of the cam plate 47. The temporary holding arm 51 is engaged with the temporary holding receiving portion 31 provided at the side edge portion of the housing space 21 of the housing body 11 in a hooked state before the connector housings 10 and 80 are fitted together. Therefore, when the fitting operation of both the connector housings 10 and 80 is started, the tip protrusion 51A is pushed by the release protrusion 92 of the male connector housing 80. The lever 40 is allowed to rotate by being bent and deformed in the unlocking direction.

カム板４７においてカム溝４１及び軸受部４７Ａが配置された側と反対側（操作アーム４９側）の端部には、雄側のコネクタハウジング８０のロック突部８９と弾性係止可能とされた係止片４２が形成されている。係止片４２は、カム板４７の後端に開口して前後方向に延びる幅方向に一対のスリット４２Ａ間において片持ち状に形成されており、その前端部を基端として上下方向に撓み変形可能とされている。両スリット４２Ａのうちの一方は、カム板４７の１角を斜めに切り落としてなる傾斜縁部４７Ｅの近傍にあってこれ以上前方には切り込めない形態となっている。 An end of the cam plate 47 opposite to the side where the cam groove 41 and the bearing portion 47A are disposed (the operation arm 49 side) can be elastically locked to the lock projection 89 of the male connector housing 80. A locking piece 42 is formed. The locking piece 42 is formed in a cantilever shape between the pair of slits 42A in the width direction that opens at the rear end of the cam plate 47 and extends in the front-rear direction, and is bent and deformed in the vertical direction with the front end as a base end. It is possible. One of the slits 42A is in the vicinity of an inclined edge portion 47E obtained by obliquely cutting one corner of the cam plate 47, and cannot be cut further forward.

そして、カム板４７の外面（上面）において係止片４２よりも前方領域には、レバー４０の回動途中でロック突部８９との干渉を回避してレバー４０の回動操作を可能とするためのロック逃がし部５２が凹設されている。係止片４２の基端部には、ロック逃がし部５２の後端から段差をなして連なる係止突部５３が形成されている。係止突部５３において前記段差を構成する前面は、図１に示すように、後方へ向けて昇り勾配となるテーパ状の案内面５３Ａとされ、係止突部５３の上面はカム板４７の一般基準面とほぼ同じ高さの平面とされる。また、係止突部５３の後面は、係止突部５３より後方に設けられた凹所５４との間に段差をなす略垂直に切り立つ係止面５３Ｂとされている。レバー４０の回動途中では、ロック突部８９が係止突部５３の案内面５３Ａに沿って係止突部５３に乗り上げられるとともに係止片４２が下方へ撓み変形させられ、ロック突部８９が係止突部５３の平面に摺接したあとレバー４０が嵌合完了位置に至ると、ロック突部８９が凹所５４に嵌まり込むとともに係止突部５３の係止面５３Ｂに抜け止め状態で係止し合うようになっている。 Then, in the outer region (upper surface) of the cam plate 47, the lever 40 can be rotated by avoiding interference with the lock projection 89 in the middle of the rotation of the lever 40 in the region ahead of the locking piece 42. For this purpose, a lock relief portion 52 is recessed. At the base end portion of the locking piece 42, a locking projection 53 is formed which is continuous with a step from the rear end of the lock release portion 52. As shown in FIG. 1, the front surface constituting the step in the locking projection 53 is a tapered guide surface 53 A that is inclined upward and the upper surface of the locking projection 53 is the cam plate 47. The plane is almost the same height as the general reference plane. The rear surface of the locking projection 53 is a locking surface 53 B that forms a step with the recess 54 provided behind the locking projection 53. During the rotation of the lever 40, the lock protrusion 89 rides on the lock protrusion 53 along the guide surface 53A of the lock protrusion 53, and the lock piece 42 is bent and deformed downward. When the lever 40 reaches the fitting completion position after sliding in contact with the flat surface of the locking projection 53, the locking projection 89 is fitted into the recess 54 and is prevented from coming off on the locking surface 53B of the locking projection 53. It is designed to lock together in a state.

係止片４２の後端部には、係止片操作部５５が一段高い位置に設定されており、ここを押し下げ操作することで係止片４２とロック突部８９とのロック状態を解除できるようになっている。カム板４７の後端部には、係止片操作部５５の全周を取り囲むようにして方形枠状の保護部４８が形成されており、この保護部４８の内側を通して係止片操作部５５の解除操作が可能とされている。そして、保護部４８は、その一辺が操作アーム４９に接合されてカム板４７の後端部より上下方向に膨出して形成され、レバー４０が嵌合完了位置にあるときにハウジング本体１１の保護部収容空間２１Ａにその全体が収容されるようになっている。 At the rear end portion of the locking piece 42, a locking piece operating portion 55 is set at a higher position, and the locked state between the locking piece 42 and the lock projection 89 can be released by pushing down this position. It is like that. A rectangular frame-shaped protective portion 48 is formed at the rear end portion of the cam plate 47 so as to surround the entire periphery of the locking piece operating portion 55, and the locking piece operating portion 55 is passed through the inside of the protective portion 48. Can be released. The protective portion 48 is formed such that one side thereof is joined to the operation arm 49 and bulges in the vertical direction from the rear end portion of the cam plate 47, and protects the housing body 11 when the lever 40 is in the fitting completion position. The whole is accommodated in the partial accommodating space 21A.

また、カム板４７の内面（下面）には、図１及び図２４に示すように、係止片４２の基端部の一側縁に沿って押圧部４４が突出して形成されている。押圧部４４は、レバー４０が嵌合完了位置に至る手前の回動終盤位置にあってロック突部８９と係止突部５３との係合に基づいて係止片４２が下方へ撓み変形したときに、検知端子６０の第２ばね部６３における被押圧部６６に対し後方から当接してこの第２ばね部６３を第１ばね部６２とともに下方へ撓ませるようになっており、さらにレバー４０が嵌合完了位置に至ると同時に、第２ばね部６３に対する押圧状態を解除して第２ばね部６３及び第１ばね部６２を弾性復元させるようになっている。押圧部４４の前端は略垂直に切り立って配されており、押圧部４４の下端は後方へ行くにつれて昇り勾配となる斜面とされている。係止片４２が最も撓み変形したときに、押圧部４４の斜面は略水平に配される。 Further, as shown in FIGS. 1 and 24, a pressing portion 44 is formed on the inner surface (lower surface) of the cam plate 47 so as to protrude along one side edge of the proximal end portion of the locking piece 42. The pressing portion 44 is at the end position of the rotation before the lever 40 reaches the fitting completion position, and the locking piece 42 is bent and deformed downward based on the engagement between the locking projection 89 and the locking projection 53. Sometimes, the second spring portion 63 of the detection terminal 60 abuts against the pressed portion 66 of the second spring portion 63 from behind, and the second spring portion 63 is bent downward together with the first spring portion 62. At the same time as the position reaches the fitting completion position, the second spring portion 63 and the first spring portion 62 are elastically restored by releasing the pressed state against the second spring portion 63. The front end of the pressing portion 44 is arranged so as to stand substantially vertically, and the lower end of the pressing portion 44 is an inclined surface having an ascending gradient as going backward. When the locking piece 42 is most bent and deformed, the slope of the pressing portion 44 is arranged substantially horizontally.

カム板４７の内面のうち、係止片４２の直前方でかつ押圧部４４と幅方向に関して内側へ少しずれた位置には、押圧部４４とは別体の先行押圧部４５が突出して形成されている。先行押圧部４５は、押圧部４４と同様に前後方向に延びる形態である一方、押圧部４４よりもその前後長さを短くして構成されている。この先行押圧部４５は、レバー４０の回動途上で押圧部４４が検知端子６０の被押圧部６６を押圧するのに先立って、被押圧部６６に後方から当接して第２ばね部６３を第１ばね部６２とともに下方へ撓ませるようになっており、さらにレバー４０の回動が進むことで被押圧部６６を乗り越えるようになっている。先行押圧部４５が第２ばね部６３に対する押圧状態を解除すると、押圧部４４が先行押圧部４５に代わって第２ばね部６３の被押圧部６６を押圧することになる。先行押圧部４５の前端の下部は後方へ向けて下り勾配となる斜面とされ、先行押圧部４５の下端は略水平なフラット面とされる。そして、先行押圧部４５が係止片４２による撓み動作の影響を受けない範囲に形成され、かつ、先行押圧部４５と押圧部４４との間に距離があいていることから、係止片４２が撓み変形する間、先行押圧部４５の後端と押圧部４４の前端との干渉を回避できるようになっている。 In the inner surface of the cam plate 47, a preceding pressing portion 45 that is separate from the pressing portion 44 protrudes and is formed at a position slightly shifted inward with respect to the pressing portion 44 in the width direction immediately before the locking piece 42. ing. The preceding pressing portion 45 is configured to extend in the front-rear direction in the same manner as the pressing portion 44, and is configured to have a shorter front-rear length than the pressing portion 44. Prior to the pressing portion 44 pressing the pressed portion 66 of the detection terminal 60 during the rotation of the lever 40, the preceding pressing portion 45 abuts against the pressed portion 66 from the rear side to cause the second spring portion 63 to move. The first spring part 62 is bent downward together with the first spring part 62, and the lever 40 is further rotated to get over the pressed part 66. When the preceding pressing portion 45 releases the pressing state against the second spring portion 63, the pressing portion 44 presses the pressed portion 66 of the second spring portion 63 instead of the preceding pressing portion 45. The lower part of the front end of the preceding pressing part 45 is an inclined surface having a downward slope toward the rear, and the lower end of the preceding pressing part 45 is a substantially horizontal flat surface. Since the preceding pressing portion 45 is formed in a range that is not affected by the bending operation by the locking piece 42 and the distance between the preceding pressing portion 45 and the pressing portion 44 is large, the locking piece 42 is provided. Interference between the rear end of the preceding pressing portion 45 and the front end of the pressing portion 44 can be avoided during the bending deformation.

ここで、レバー４０の回動操作に伴い、接点用端子９８が検知端子６０の内部に進入することになるものの、レバー４０の回動途上では先行押圧部４５とこれに続く押圧部４４とが第２ばね部６３とともに第１ばね部６２を押圧して第１ばね部６２の接点部６５を下位へ押しやっているので、接点用端子９８と第１ばね部６２の接点部６５とは非接触状態に保たれる。一方、レバー４０が嵌合完了位置に至ると、第２ばね部６３に対する押圧部４４の押圧状態が解除され、これに伴って第２ばね部６３が第１ばね部６２とともに弾性復元することにより、接点用端子９８と第１ばね部６２の接点部６５とが接触して検知回路を閉成することになる。 Here, the contact terminal 98 enters the inside of the detection terminal 60 as the lever 40 is rotated, but the preceding pressing portion 45 and the subsequent pressing portion 44 are in the middle of the rotation of the lever 40. Since the first spring part 62 is pressed together with the second spring part 63 to push the contact part 65 of the first spring part 62 downward, the contact terminal 98 and the contact part 65 of the first spring part 62 are not in contact with each other. Kept in a state. On the other hand, when the lever 40 reaches the fitting completion position, the pressing state of the pressing portion 44 against the second spring portion 63 is released, and the second spring portion 63 and the first spring portion 62 are elastically restored along with this. The contact terminal 98 and the contact portion 65 of the first spring portion 62 come into contact with each other, thereby closing the detection circuit.

レバー４０の操作アーム４９は、図１３に示すように、高さ方向に延びる長板状をなしており、レバー４０が嵌合完了位置に至ったときに、ハウジング本体１１の段差凹部２９Ｂに嵌合するとともに、その前端がハウジング本体１１の当て面２９Ａに対し高さ方向に押し当てられ、この当て面２９Ａを前方つまり嵌合が進む方向へ押し込むようになっている。操作アーム４９の前端は押し面４９Ａとして機能しており、両コネクタハウジング１０，８０が傾いた姿勢で嵌合するのを防止する役割を担っている。 As shown in FIG. 13, the operating arm 49 of the lever 40 has a long plate shape extending in the height direction. When the lever 40 reaches the fitting completion position, the operating arm 49 is fitted in the stepped recess 29B of the housing body 11. At the same time, the front end is pressed against the contact surface 29A of the housing body 11 in the height direction, and the contact surface 29A is pushed forward, that is, in the direction in which the fitting proceeds. The front end of the operation arm 49 functions as a pushing surface 49A and plays a role of preventing the connector housings 10 and 80 from being fitted in an inclined posture.

レバー４０の姿勢矯正アーム４６は、図２４に示すように、ハウジング本体１１を間に挟んでカム板４７と対向する位置に配置されており、その幅寸法がカム板４７よりも幅狭とされてリテーナ９３との干渉を回避可能となっている。姿勢矯正アーム４６には、カム板４７の軸受部４７Ａと上下方向に関して同軸上の位置に、支持軸２７を嵌合可能な軸受部４６Ａが厚み方向に貫通して形成されている。姿勢矯正アーム４６の軸受部４６Ａの内縁には、抜け止め突部２７Ａを嵌め込むための逃がし溝４６Ｂが切り欠き形成されているとともに、抜け止め突部２７Ａとレバー４０の抜け方向で係合する係合縁部４６Ｅが形成されている。 As shown in FIG. 24, the posture correcting arm 46 of the lever 40 is disposed at a position facing the cam plate 47 with the housing body 11 interposed therebetween, and the width dimension thereof is narrower than that of the cam plate 47. Thus, interference with the retainer 93 can be avoided. The posture correcting arm 46 is formed with a bearing portion 46A through which the support shaft 27 can be fitted in the thickness direction at a position coaxial with the bearing portion 47A of the cam plate 47 in the vertical direction. On the inner edge of the bearing portion 46A of the posture correcting arm 46, an escape groove 46B for fitting the retaining projection 27A is formed in a notch, and is engaged with the retaining projection 27A in the direction in which the lever 40 is detached. An engagement edge 46E is formed.

姿勢矯正アーム４６の先端部（操作アーム４９から離れた端部）には、レバー４０の回動方向と略直交する方向に沿って引っ掛け面４３Ａを有する引っ掛け部４３が形成されている。引っ掛け部４３は、両コネクタハウジング１０，８０が幅方向に関して正規の嵌合姿勢から傾いた状態で嵌合が進む場合に、レバー４０が嵌合完了位置に至る直前に、雄側のコネクタハウジング８０の受け部９１の後面にその引っ掛け面４３Ａを対面させてこの受け部９１と引っ掛け状態で係合するようになっており、さらにレバー４０が嵌合完了位置に至る過程で受け部９１を引き込むことにより、両コネクタハウジング１０，８０の嵌合姿勢を矯正する役割を担っている。 A hook 43 having a hook surface 43 A is formed along the direction substantially orthogonal to the rotation direction of the lever 40 at the tip of the posture correction arm 46 (the end away from the operation arm 49). The hook 43 is provided with the male connector housing 80 immediately before the lever 40 reaches the mating completion position when the mating proceeds in a state where both the connector housings 10, 80 are inclined from the normal mating posture in the width direction. The catching surface 43A is opposed to the rear surface of the receiving portion 91 so as to be engaged with the receiving portion 91 in a hooked state, and the receiving portion 91 is pulled in the process of the lever 40 reaching the fitting completion position. Therefore, it plays a role of correcting the fitting posture of the connector housings 10 and 80.

ところで、レバー４０は、図７及び図２０に示すように、嵌合初期位置では操作アーム４９をハウジング本体１１の後面よりも後方へ位置させることでハウジング本体１１の後面に突出状態で配置される一方、嵌合完了位置では、図１０及び図１６に示すように、その後端面をハウジング本体１１の後端面に略面一で連ねることでハウジング本体１１の後端面との間に段差が生じないようにしてある。したがって、レバー４０とハウジング本体１１との面一状態を確認することにより、両コネクタハウジング１０，８０が正規嵌合されたか否かを判断できるようになっている。 By the way, as shown in FIGS. 7 and 20, the lever 40 is disposed in a protruding state on the rear surface of the housing body 11 by positioning the operation arm 49 rearward of the rear surface of the housing body 11 at the initial fitting position. On the other hand, at the fitting completion position, as shown in FIGS. 10 and 16, the rear end surface is connected to the rear end surface of the housing body 11 so as to be substantially flush with each other so that no step is generated between the rear end surface of the housing body 11. It is. Therefore, by checking the flush state between the lever 40 and the housing body 11, it is possible to determine whether or not the two connector housings 10 and 80 are properly fitted.

次に、本実施形態の作用を説明する。まず、雄側のコネクタハウジング８０は、雄側端子金具９９とプリント回路基板の導電路との導通をとりつつ基板の表面に固定され、雌側のコネクタハウジング１０との嵌合動作が開始されるまで待ち受け状態とされる。 Next, the operation of this embodiment will be described. First, the male connector housing 80 is fixed to the surface of the board while establishing conduction between the male terminal fitting 99 and the conductive path of the printed circuit board, and the mating operation with the female connector housing 10 is started. It will be in a standby state.

一方、雌側のコネクタハウジング１０においては、リテーナ９３をハウジングのリテーナ装着孔１７に差し込んで仮係止位置に留め置き、その状態でハウジング本体１１の収容空間２１にレバー４０のカム板４７をスライド装着してカム板４７の軸受部４７Ａを支軸２５に支持させるとともに、その反対側で姿勢矯正アーム４６の軸受部４６Ａを支持軸２７に支持させることにより、レバー４０を嵌合完了位置に留めた状態でハウジング本体１１に取り付ける。このとき、レバー４０の姿勢矯正アーム４６とリテーナ９３とが厚み方向で重複する位置関係にあるが、図１５に示すように、リテーナ９３の逃がし凹部９６に姿勢矯正アーム４６の一部が進入することによって両者の干渉が回避される。 On the other hand, in the female connector housing 10, the retainer 93 is inserted into the retainer mounting hole 17 of the housing and retained in the temporary locking position, and in this state, the cam plate 47 of the lever 40 is slid and mounted in the housing space 21 of the housing body 11. Then, the bearing portion 47A of the cam plate 47 is supported by the support shaft 25, and the bearing portion 46A of the posture correcting arm 46 is supported by the support shaft 27 on the opposite side, whereby the lever 40 is held at the fitting completion position. Attach to the housing body 11 in a state. At this time, although the posture correction arm 46 of the lever 40 and the retainer 93 are in a positional relationship overlapping in the thickness direction, a part of the posture correction arm 46 enters the relief recess 96 of the retainer 93 as shown in FIG. This avoids interference between the two.

続いて、上記した雌側のコネクタハウジング１０を雌側端子金具９７の組み付け現場へ搬送する。組み付け現場では、ハウジング本体１１のキャビティ１２内へ後方から雌側端子金具９７を自動機によって挿入するわけであるが、この場合に、レバー４０の後端とハウジング本体１１の後端との間に段差が無いので、雌側端子金具９７の挿入動作を円滑に行うことが可能となる。全ての雌側端子金具９７を挿入したら、リテーナ９３を本係止位置へ押し込み、雌側端子金具９７をランス１３とともに二重に抜け止めする。リテーナ９３を本係止位置に押し込むことでリテーナ９３の浮き上がりが無くなるので、レバー４０の回動動作が許容される。なお、雌側端子金具９７とともに短絡端子７０及び検知端子６０もハウジング本体１１に組み付けておく。 Subsequently, the female connector housing 10 described above is conveyed to the assembly site of the female terminal fitting 97. At the assembly site, the female terminal fitting 97 is inserted into the cavity 12 of the housing main body 11 from the rear by an automatic machine. In this case, the rear end of the lever 40 and the rear end of the housing main body 11 are inserted. Since there is no step, the insertion operation of the female terminal fitting 97 can be performed smoothly. When all of the female terminal fittings 97 have been inserted, the retainer 93 is pushed into the final locking position, and the female terminal fittings 97 together with the lance 13 are prevented from coming off. Since the retainer 93 is not lifted up by pushing the retainer 93 into the main locking position, the lever 40 is allowed to rotate. Note that the short-circuit terminal 70 and the detection terminal 60 together with the female terminal fitting 97 are also assembled to the housing body 11.

次いで、図７及び図２０に示すように、レバー４０を嵌合初期位置まで回動して、仮保持アーム５１の先端突起５１Ａをハウジング本体１１の仮保持受け部３１に引っ掛け、カム溝４１の入り口とハウジング本体１１のカムピン導入溝２２Ａの入り口とを上下方向で連通させる。この状態で、待ち受け状態にある雄側のコネクタハウジング８０のフード部８１における両嵌合凹部８３に対して対応する雌側のコネクタハウジング１０を浅く嵌め入れる。すると、図８に示すように、解除突部９２が仮保持アーム５１と仮保持受け部３１との間に分け入って両者の引っ掛け状態を解除するとともに、カムピン８８がカムピン導入溝２２Ａ及びカム溝４１に進入し、かつ、ロック突部８９がガイド溝２２Ｂに進入する。 Next, as shown in FIGS. 7 and 20, the lever 40 is rotated to the initial fitting position so that the tip protrusion 51 A of the temporary holding arm 51 is hooked on the temporary holding receiving portion 31 of the housing body 11. The entrance and the entrance of the cam pin introduction groove 22A of the housing body 11 are communicated in the vertical direction. In this state, the corresponding female connector housing 10 is shallowly fitted into both fitting recesses 83 in the hood portion 81 of the male connector housing 80 in the standby state. Then, as shown in FIG. 8, the release protrusion 92 is inserted between the temporary holding arm 51 and the temporary holding receiving portion 31 to release the hooked state between them, and the cam pin 88 is connected to the cam pin introduction groove 22 A and the cam groove. 41, and the lock protrusion 89 enters the guide groove 22B.

その状態から操作アーム４９を摘んでレバー４０を図８に示す矢線Ｘ方向に回動すると、カムピン８８がカムピン導入溝２２Ａに沿って移動するとともにロック突部８９がガイド溝２２Ｂに沿って移動し、かつ、図２に示すように、レバー４０の回動初期段階で、短絡端子７０の弾性片７１とこれと接触状態にある雌側端子金具９７との間に短絡解除片８７が分け入って両者の短絡状態が解除される。また、レバー４０の回動初期段階では、後方から先行押圧部４５が検知端子６０の被押圧部６６に当たり、先行押圧部４５と被押圧部６６の両斜面が両コネクタハウジング１０，８０の嵌合方向に沿って摺接し合って第２ばね部６３が撓み変形させられ、さらに第２ばね部６３の前端部が傾倒するのに伴って第１ばね部６２が押し下げられて、図３に示すように、第１ばね部６２の接点部６５の高さが対応する接点用端子９８の高さよりも低くなる。かくして接点用端子９８が検知端子６０の内部に進入する早い段階で、第１ばね部６２の押し下げ動作が行われ、接点用端子９８は接点部６５と非当接状態で検知端子６０の内奥へ進入することになる。 If the operating arm 49 is picked from this state and the lever 40 is rotated in the direction of the arrow X shown in FIG. 8, the cam pin 88 moves along the cam pin introduction groove 22A and the lock projection 89 moves along the guide groove 22B. In addition, as shown in FIG. 2, at the initial turning stage of the lever 40, the short-circuit releasing piece 87 is divided between the elastic piece 71 of the short-circuit terminal 70 and the female-side terminal fitting 97 in contact with the elastic piece 71. Thus, the short circuit state of both is released. Further, at the initial rotation stage of the lever 40, the preceding pressing portion 45 hits the pressed portion 66 of the detection terminal 60 from the rear, and both inclined surfaces of the preceding pressing portion 45 and the pressed portion 66 are fitted to the connector housings 10 and 80. As shown in FIG. 3, the second spring portion 63 is slidably contacted in the direction to bend and deform, and further, the first spring portion 62 is pushed down as the front end portion of the second spring portion 63 is tilted. Further, the height of the contact portion 65 of the first spring portion 62 is lower than the height of the corresponding contact terminal 98. Thus, at the early stage when the contact terminal 98 enters the inside of the detection terminal 60, the first spring portion 62 is pushed down, and the contact terminal 98 is not in contact with the contact portion 65 and is located in the inner part of the detection terminal 60. Will enter.

レバー４０の回動が進むと、図４に示すように、係止片４２の係止突部５３がロック突部８９に乗り上げられて、係止片４２が下方へ撓み変形させられ、それに伴って先行押圧部４５が被押圧部６６から離間するとともに押圧部４４の前端が先行押圧部４５に代わって被押圧部６６を下方へ押さえ付ける。この間、第２ばね部６３は撓み状態を維持しているので、第１ばね部６２の接点部６５の高さ位置が上昇することはなく、第１ばね部６２の接点部６５と接点用端子９８との非接触状態が保たれる。図５及び図９に示すように、係止突部５３がロック突部８９を通過する過程では、押圧部４４の斜面が被押圧部６６をレバー４０の回動軌跡に沿った円弧を描きつつ摺動し、これによって第２ばね部６３及び第１ばね部６２の撓み状態が維持される。 As the rotation of the lever 40 proceeds, as shown in FIG. 4, the locking projection 53 of the locking piece 42 rides on the locking projection 89, and the locking piece 42 is bent and deformed downward. Thus, the preceding pressing portion 45 is separated from the pressed portion 66 and the front end of the pressing portion 44 presses the pressed portion 66 downward instead of the preceding pressing portion 45. During this time, since the second spring part 63 maintains the bent state, the height position of the contact part 65 of the first spring part 62 does not rise, and the contact part 65 of the first spring part 62 and the contact terminal The non-contact state with 98 is maintained. As shown in FIGS. 5 and 9, in the process in which the locking protrusion 53 passes through the lock protrusion 89, the inclined surface of the pressing portion 44 draws an arc along the rotation locus of the lever 40 while the inclined surface of the pressing portion 44. By sliding, the bent state of the second spring portion 63 and the first spring portion 62 is maintained.

そして、図６に示すように、レバー４０が嵌合完了位置に至ることで係止片４２の係止突部５３がロック突部８９を乗り越えると、係止片４２が元の自然状態に復元するとともに、押圧部４４が被押圧部６６から離間して押圧状態が解除され、それに伴って第２ばね部６３及び第１ばね部６２が元の自然状態に復元する。すると、第１ばね部６２の接点部６５の高さ位置が上昇して接点用端子９８に対し下方から押し当てられ、両者の導通がとられることで検知回路が閉成される。かくして接点用端子９８と検知端子６０の接続に起因する信号を電気的に検知することにより、レバー４０が嵌合完了位置に至って両コネクタハウジング１０，８０が正規嵌合されたことを知ることができる。もちろん、雌雄の両端子金具９７，９９の導通もとられて所定の回路が構成されることとなる。 As shown in FIG. 6, when the locking projection 53 of the locking piece 42 gets over the locking projection 89 by the lever 40 reaching the fitting completion position, the locking piece 42 is restored to the original natural state. At the same time, the pressing portion 44 is separated from the pressed portion 66 to release the pressing state, and the second spring portion 63 and the first spring portion 62 are restored to the original natural state accordingly. Then, the height position of the contact portion 65 of the first spring portion 62 rises and is pressed against the contact terminal 98 from below, and the detection circuit is closed by connecting the both. Thus, by electrically detecting a signal resulting from the connection between the contact terminal 98 and the detection terminal 60, it is known that the lever 40 has reached the fitting completion position and the connector housings 10, 80 have been properly fitted. it can. Of course, conduction between the male and female terminal fittings 97, 99 is established to constitute a predetermined circuit.

また、レバー４０が嵌合完了位置に至ると、カム板４７がハウジング本体１１の収容空間２１に収容されるとともに保護部４８が保護部収容空間２１Ａに収容され、かつ、操作アーム４９がハウジング本体１１の段差凹部２９Ｂに嵌め込まれる。すると、図１０及び図１６に示すように、レバー４０の後端とハウジング本体１１の後端とが略面一で連なって段差がなくなり、これを確認することによってもレバー４０が嵌合完了位置に至ったことを知ることができる。 When the lever 40 reaches the fitting completion position, the cam plate 47 is accommodated in the accommodating space 21 of the housing main body 11, the protective portion 48 is accommodated in the protective portion accommodating space 21A, and the operation arm 49 is accommodated in the housing main body. 11 stepped recesses 29B. Then, as shown in FIGS. 10 and 16, the rear end of the lever 40 and the rear end of the housing main body 11 are substantially flush with each other to eliminate a step, and the lever 40 can be fitted to the fitting completion position by checking this. You can know that you have reached.

ところで、本実施形態においては、レバー４０の回動中心軸が幅方向に関して偏心した位置に設定されているとともに、図１２に示すように、カム溝４１とカムピン８８との係合領域がレバー４０のカム板４７のみに設定されているという事情があるため、回動中心軸側及びカム溝４１とカムピン８８との係合領域側にレバー４０の嵌合力が偏って作用し、そちら側で嵌合が早く進むのに対し、中心軸から離れた側及びカム溝４１とカムピン８８との係合領域側とは反対側で嵌合が遅くなるおそれがある。 By the way, in the present embodiment, the rotation central axis of the lever 40 is set at a position eccentric with respect to the width direction, and the engagement region between the cam groove 41 and the cam pin 88 is the lever 40 as shown in FIG. Therefore, the fitting force of the lever 40 is biased on the rotation center axis side and the engagement region side of the cam groove 41 and the cam pin 88, and the engagement is performed on that side. While the alignment proceeds faster, the fitting may be delayed on the side away from the central axis and on the side opposite to the engagement region side between the cam groove 41 and the cam pin 88.

しかるに本実施形態においては、仮に両コネクタハウジング１０，８０が上下方向に関して正規の嵌合姿勢から傾いた姿勢をとっていても、図１５に示すように、レバー４０が嵌合完了位置に至る直前に、レバー４０の引っ掛け部４３が受け部９１を引っ掛け状態で引き込み、これにより、遅れ勝ちであった姿勢矯正アーム４６側における嵌合動作を早く進めるようになっているので、レバー４０が嵌合完了位置に至れば、両コネクタハウジング１０，８０が正規の嵌合姿勢に矯正されることとなる。 However, in this embodiment, even if both the connector housings 10 and 80 are inclined from the normal fitting posture with respect to the vertical direction, as shown in FIG. 15, the lever 40 immediately before reaching the fitting completion position. In addition, the hooking portion 43 of the lever 40 pulls the receiving portion 91 in the hooked state, so that the fitting operation on the posture correcting arm 46 side that has been delayed is advanced quickly, so the lever 40 is fitted. When the completion position is reached, both the connector housings 10 and 80 are corrected to the normal fitting posture.

また、仮に両コネクタハウジング１０，８０が幅方向に関して正規の嵌合姿勢から傾いた姿勢をとっていても、図１３に示すように、レバー４０が嵌合完了位置に至る直前に、レバー４０の操作アーム４９の押し面４９Ａがハウジング本体１１の当て面２９Ａに当たってフード部８１側へ押し込み、これにより、遅れ勝ちであった中心軸から離れた端部における嵌合動作を早く進めるようになっているので、レバー４０が嵌合完了位置に至れば、両コネクタハウジング１０，８０が正規の嵌合姿勢に矯正されることとなる。 Further, even if both connector housings 10 and 80 are inclined from the normal fitting posture with respect to the width direction, as shown in FIG. 13, immediately before the lever 40 reaches the fitting completion position, The pressing surface 49A of the operation arm 49 hits the contact surface 29A of the housing main body 11 and pushes it toward the hood portion 81, so that the fitting operation at the end portion away from the central axis that has been delayed is advanced quickly. Therefore, when the lever 40 reaches the fitting completion position, both the connector housings 10 and 80 are corrected to the normal fitting posture.

さらに、両コネクタハウジング１０，８０の嵌合途上では、ハウジング本体１１のガイド溝２２Ｂにロック突部８９が摺接可能に移動するとともにハウジング本体１１のカムピン導入溝２２Ａにカムピン８８が同じく摺接可能に移動するので、これらが移動している間、両コネクタハウジング１０，８０が嵌合案内されて姿勢が傾くのを防止できる。しかも、レバー４０が嵌合完了位置に至ると、図１４に示すように、ロック突部８９がハウジング本体１１の覆い壁２２におけるガイド溝２２Ｂの奥端とレバー４０の係止片４２の係止突部５３との間に位置決め状態で挟まれるので、レバー４０がロック状態となることをもって両コネクタハウジング１０，８０の嵌合姿勢が正規姿勢であることを知ることができる。 Further, during the fitting of both the connector housings 10 and 80, the lock projection 89 is slidably moved in the guide groove 22B of the housing body 11, and the cam pin 88 is also slidable in the cam pin introduction groove 22A of the housing body 11. Therefore, it is possible to prevent the connector housings 10 and 80 from being fitted and guided and tilting while they are moving. Moreover, when the lever 40 reaches the fitting completion position, as shown in FIG. 14, the lock projection 89 engages the back end of the guide groove 22 B in the cover wall 22 of the housing body 11 and the engagement piece 42 of the lever 40. Since it is sandwiched between the projecting portion 53 and the protruding portion 53, it can be known that the fitting posture of the connector housings 10 and 80 is the normal posture when the lever 40 is in the locked state.

さて一般に、レバー式コネクタでは、カムピン８８がカム溝４１に係合した状態でレバー４０を回動すると、これらの間に作用する嵌合力（両コネクタハウジング１０，８０を嵌合させる方向に作用する力）を通じてコネクタハウジング１０，８０同士の嵌合がなされる。しかし、本実施形態のように、カム板４７が雌側のコネクタハウジング１０の一面にのみ配されているものでは、上記した嵌合力が両コネクタハウジング１０，８０間でバランスしにくいという事情がある。つまり、カム板４７が設けられた側が先行して雄側のコネクタハウジング８０に嵌合し、逆に、カム板４７が設けられていない反対側では嵌合が遅れるため、両コネクタハウジング１０，８０は高さ方向の中心軸で傾斜した姿勢で嵌合するおそれがある。また、カムピン８８とカム溝４１との係合が、両コネクタハウジング１０，８０の幅方向に関して偏位していれば、両コネクタハウジング１０，８０は幅方向の中心軸から傾斜した姿勢で嵌合してしまうおそれがある。 In general, in the lever type connector, when the lever 40 is rotated in a state where the cam pin 88 is engaged with the cam groove 41, the fitting force acting between them (acts in the direction in which both the connector housings 10, 80 are fitted). The connector housings 10 and 80 are engaged with each other through force. However, in the case where the cam plate 47 is disposed only on one surface of the female connector housing 10 as in the present embodiment, the above-described fitting force is difficult to balance between the connector housings 10 and 80. . That is, the side on which the cam plate 47 is provided is first fitted into the male connector housing 80, and conversely, the fitting is delayed on the opposite side where the cam plate 47 is not provided. May be fitted in a posture inclined with respect to the central axis in the height direction. Further, if the engagement between the cam pin 88 and the cam groove 41 is deviated with respect to the width direction of the two connector housings 10 and 80, the two connector housings 10 and 80 are fitted in a posture inclined from the central axis in the width direction. There is a risk of it.

その点、本実施形態によれば、カム溝４１とカムピン８８との係合箇所に加え、嵌合完了の際には他の係合箇所を設け、両コネクタハウジング１０，８０の幅方向あるいは高さ方向で嵌合力がバランスするようにしたため、両コネクタハウジング１０，８０を真っ直ぐな嵌合姿勢に矯正させることができる。 In this respect, according to the present embodiment, in addition to the engagement portion between the cam groove 41 and the cam pin 88, another engagement portion is provided when the fitting is completed, and the width direction or height of both the connector housings 10 and 80 are increased. Since the fitting force is balanced in the vertical direction, both connector housings 10, 80 can be corrected to a straight fitting posture.

詳しくは、既述したように、カム板４７が設けられた側で両コネクタハウジング１０，８０の嵌合が先行しても、両コネクタハウジング１０，８０の嵌合が完了する際には、カムピン８８とカム溝４１との係合箇所と両コネクタハウジング１０，８０の高さ方向に関する中心軸を挟んだ対称位置において、姿勢矯正アーム４６の引っ掛け部４３と受け部９１との係合によって両コネクタハウジング１０，８０を嵌合させる方向の力が生じるため、両コネクタハウジング１０，８０の高さ方向の中心軸を挟んだ両側で嵌合力がバランスして作用し、結果、嵌合が遅れていた側での嵌合が進み、両コネクタハウジング１０，８０が真っ直ぐな嵌合姿勢に矯正される。 More specifically, as described above, even when the connector housings 10 and 80 are fitted on the side where the cam plate 47 is provided, the cam pins are completed when the fitting of the connector housings 10 and 80 is completed. 88 and the cam groove 41 and the connector housings 10 and 80 at the symmetrical positions with respect to the center axis with respect to the height direction of the connector housings 10 and 80 by engaging the hook portion 43 and the receiving portion 91 of the posture correcting arm 46. Since a force in the direction in which the housings 10 and 80 are fitted is generated, the fitting forces act on both sides across the central axis in the height direction of both the connector housings 10 and 80, and as a result, the fitting is delayed. The connector housing 10 and 80 are corrected to a straight fitting posture.

また、カムピン８８とカム溝４１との係合箇所が両コネクタハウジング１０，８０の幅方向に関する中心軸から一方へ偏位しているため、この係合側でレバー４０が設けられている雌側のコネクタハウジング１０は雄側のコネクタハウジング８０に対して先行して嵌合がなされることがある。しかし、嵌合が完了する際には、カムピン８８による係合箇所とは幅方向の反対側で、レバー４０の操作アーム４９の押し面４９Ａが雌側のコネクタハウジング１０を押して雄側のコネクタハウジング８０を押し入れるため、両コネクタハウジング１０，８０が真っ直ぐな嵌合姿勢に矯正される。 Further, since the engaging portion between the cam pin 88 and the cam groove 41 is deviated from the central axis in the width direction of both the connector housings 10 and 80, the female side on which the lever 40 is provided on this engaging side. The connector housing 10 may be pre-fitted to the male connector housing 80 in advance. However, when the fitting is completed, the pushing surface 49A of the operation arm 49 of the lever 40 pushes the female connector housing 10 on the opposite side of the engagement portion by the cam pin 88 in the width direction. Since 80 is pushed in, both connector housings 10, 80 are corrected to a straight fitting posture.

さらに、カムピン８８とカム溝４１との係合箇所が両コネクタハウジング１０，８０の幅方向に関する中心軸から一方へ偏位しているため、この係合側でレバー４０が設けられている雌側のコネクタハウジング１０は雄側のコネクタハウジング８０に対して先行して嵌合がなされるおそれがあるが、本実施形態によれば、上記係合箇所とは幅方向の反対側でロック突部８９がガイド溝２２Ｂによる案内を受けるため、雌側のコネクタハウジング１０の嵌合姿勢は正規姿勢に保持され、嵌合完了した時点で、係止片４２が雄側のコネクタハウジング８０のロック突部８９と係止して両コネクタハウジング１０，８０の嵌合状態がロックされる。 Further, since the engaging portion between the cam pin 88 and the cam groove 41 is deviated from the central axis in the width direction of the two connector housings 10 and 80, the female side on which the lever 40 is provided on this engaging side. However, according to the present embodiment, the locking projection 89 on the opposite side in the width direction from the above-mentioned engaging portion may be fitted to the male connector housing 80. Since the guide groove 22B receives the guide, the fitting posture of the female connector housing 10 is maintained in a normal posture, and when the fitting is completed, the locking piece 42 is the locking protrusion 89 of the male connector housing 80. And the fitting state of both connector housings 10 and 80 is locked.
