The frame portion 162 and a lock piece locking portion 163 formed on the one outer wall 113 of the first connector housing 110 are configured.
　弾性ロック片１６１は、図２０に示すように、嵌合操作レバー１３０の板厚方向（図２０の矢印Ｙ３方向）に撓み変位可能な弾性片１６１ａと、この弾性片１６１ａの先端寄りの位置に突設されたロック突起１６１ｂと、弾性片１６１ａの先端に設けられた解除用操作部１６１ｃと、を備えている。 As shown in FIG. 20, the elastic lock piece 161 has an elastic piece 161a that can be bent and displaced in the thickness direction of the fitting operation lever 130 (in the direction of arrow Y3 in FIG. 20), and a position closer to the tip of the elastic piece 161a. A lock protrusion 161b provided in a projecting manner and a release operation portion 161c provided at the tip of the elastic piece 161a are provided.
　この弾性ロック片１６１は、嵌合操作レバー１３０が回動終了位置Ｐ２に到達したときに、図２２に示すように、ロック突起１６１ｂが第１のコネクタハウジング１１０のロック片係止部１６３に係合されることで、嵌合操作レバー１３０を回動終了位置Ｐ２に固定する。 When the fitting operation lever 130 reaches the rotation end position P2, the elastic lock piece 161 has the lock protrusion 161b engaged with the lock piece engaging portion 163 of the first connector housing 110 as shown in FIG. By fitting, the fitting operation lever 130 is fixed to the rotation end position P2.
　弾性ロック片１６１の解除用操作部１６１ｃは、嵌合操作レバー１３０が回動終了位置Ｐ２にロックされている状態を解除するときに押下する部位である。図２２に示すようにロック突起１６１ｂがロック片係止部１６３に係合している状態で、矢印Ｙ４方向に解除用操作部１６１ｃが押下されると、弾性片１６１ａが矢印Ｙ４方向に撓んで、係合が解除される。 The release operation portion 161c of the elastic lock piece 161 is a portion to be pressed when releasing the state where the fitting operation lever 130 is locked at the rotation end position P2. As shown in FIG. 22, when the release operating portion 161c is pressed in the arrow Y4 direction while the lock protrusion 161b is engaged with the lock piece locking portion 163, the elastic piece 161a is bent in the arrow Y4 direction. , The engagement is released.

　ところが、特許文献１のレバー式コネクタ１００の場合、板状の嵌合操作レバー１３０は、レバーロック機構１６０を構成する弾性ロック片１６１が当該嵌合操作レバー１３０の板厚方向に撓む構造であり、弾性ロック片１６１の撓み代を確保するために、当該嵌合操作レバー１３０の板厚方向の寸法が増大するという問題があった。そして、この嵌合操作レバー１３０の板厚方向の寸法の増大が、第１のコネクタハウジング１１０に装備されるレバー収容空間１１１の大型化を招き、レバー式コネクタの大型化を招くという問題があった。 However, in the case of the lever-type connector 100 of Patent Document 1, the plate-like fitting operation lever 130 has a structure in which the elastic lock piece 161 constituting the lever locking mechanism 160 is bent in the plate thickness direction of the fitting operation lever 130. In order to secure the bending allowance of the elastic lock piece 161, there is a problem that the dimension of the fitting operation lever 130 in the thickness direction increases. Further, the increase in the dimension of the fitting operation lever 130 in the plate thickness direction leads to an increase in the size of the lever housing space 111 provided in the first connector housing 110, and an increase in the size of the lever-type connector. It was.
　また、特許文献１のレバー式コネクタ１００の場合、弾性ロック片１６１が不用意に押下されてロック状態が不用意に解除されないように、解除用操作部１６１ｃの周囲を囲う誤操作防止用枠部１６２を装備することが必要となっている。そこで、誤操作防止用枠部１６２の装備のために、嵌合操作レバー１３０の構造が複雑化し、製造コストの高額化を招くという問題もあった。 Further, in the case of the lever-type connector 100 of Patent Document 1, an erroneous operation prevention frame portion 162 that surrounds the release operation portion 161c so that the elastic lock piece 161 is not carelessly pressed and the locked state is not carelessly released. It is necessary to equip. Therefore, there is a problem that the structure of the fitting operation lever 130 is complicated due to the provision of the erroneous operation preventing frame portion 162 and the manufacturing cost is increased.
　そこで、本発明の目的は、上記課題を解消することに係り、板状の嵌合操作レバーの構造を単純化すると同時に当該嵌合操作レバーの板厚方向の寸法の増大を抑止して、製造コストの低減と小型化とを図ることのできるレバー式コネクタを提供することにある。 Therefore, an object of the present invention is to solve the above-mentioned problems, simplify the structure of the plate-like fitting operation lever, and at the same time suppress the increase in the dimension of the fitting operation lever in the thickness direction. It is an object of the present invention to provide a lever type connector that can achieve cost reduction and downsizing.
　本発明の前述した目的は、下記の構成により達成される。
　（１）　一外側壁の内側にコネクタハウジング相互の嵌合方向に貫通したレバー収容空間が画成された第１のコネクタハウジングと、
　前記第１のコネクタハウジングの内側に嵌合する嵌合部と、前記一外側壁の内面と対向する前記嵌合部の外側面に突設された嵌合用突起と、を備えた第２のコネクタハウジングと、
　前記レバー収容空間に回動可能に装備され、前記第１のコネクタハウジングと前記第２のコネクタハウジングとが嵌合開始位置に突き合わされた状態で回動初期位置から回動終了位置に回動されると、前記嵌合用突起が摺動可能なカム溝によって前記嵌合用突起が引き寄せられて、前記第１のコネクタハウジングと前記第２のコネクタハウジングとを嵌合完了状態にする略板状の嵌合操作レバーと、
　前記嵌合操作レバーが前記回動終了位置に到達したときに前記嵌合操作レバーを前記回動終了位置にロックするレバーロック機構と、を備えるレバー式コネクタであって、
　前記レバーロック機構は、前記嵌合操作レバーの一方の表面に凹んで形成されたロック用係止凹部と、前記ロック用係止凹部が設けられている前記一方の表面と対向するように、前記レバー収容空間を画成した前記第１のコネクタハウジングの壁面に突設されて、前記嵌合操作レバーが前記回動終了位置に到達したときに前記ロック用係止凹部に係合するロック用突起と、を備えるレバー式コネクタ。 The above-described object of the present invention is achieved by the following configuration.
(1) a first connector housing in which a lever housing space penetrating in the fitting direction between the connector housings is defined inside the one outer wall;
A second connector comprising: a fitting portion that fits inside the first connector housing; and a fitting projection that projects from the outer surface of the fitting portion facing the inner surface of the one outer wall. A housing;
The lever housing space is pivotally equipped, and the first connector housing and the second connector housing are rotated from the initial rotation position to the final rotation position in a state where the first connector housing and the second connector housing are abutted with the fitting start position. Then, the fitting protrusion is drawn by the cam groove in which the fitting protrusion is slidable, so that the first connector housing and the second connector housing are brought into a fitting completed state. Joint operation lever,
A lever-type connector that locks the fitting operation lever at the rotation end position when the fitting operation lever reaches the rotation end position;
The lever lock mechanism is configured so that the locking engagement recess formed in a recess on one surface of the fitting operation lever and the one surface provided with the lock engagement recess are opposed to the one surface. A locking projection that protrudes from the wall surface of the first connector housing that defines a lever housing space and engages the locking locking recess when the fitting operation lever reaches the rotation end position. And a lever-type connector.
　（２）　前記ロック用係止凹部は、直線状に延在する溝であり、
　前記ロック用突起は、直線状に延在する突条である上記（１）に記載のレバー式コネクタ。 (2) The locking recess is a groove extending linearly,
The lever-type connector according to (1), wherein the locking protrusion is a linearly extending protrusion.
　（３）　前記嵌合操作レバーの前記ロック用係止凹部に隣接し、前記回動終了位置への回動時に回動方向の先方に位置する領域には、前記ロック用突起を前記ロック用係止凹部に誘導するテーパ面が設けられた上記（１）又は（２）に記載のレバー式コネクタ。 (3) The locking protrusion is placed in the lock engagement recess in the area adjacent to the locking latching recess of the fitting operation lever and located at the tip of the rotation direction when rotating to the rotation end position. The lever type connector according to the above (1) or (2), wherein a tapered surface for guiding to the stop recess is provided.
　上記（１）の構成によれば、嵌合操作レバーを回動終了位置にロックするレバーロック機構は、嵌合操作レバーの一方の表面に凹んで形成されたロック用係止凹部と、該ロック用係止凹部を係止するように第１のコネクタハウジングに設けられたロック用突起とで構成されている。 According to the configuration of (1) above, the lever lock mechanism that locks the fitting operation lever at the rotation end position includes the locking engagement recess formed on the one surface of the fitting operation lever and the lock. And a locking protrusion provided on the first connector housing to lock the locking recess.
　即ち、嵌合操作レバーは、レバーロック機構としては、一方の表面にロック用係止凹部を設けるだけで良く、板厚方向に撓み変位して板厚方向の寸法の増大を招く弾性ロック片が不要なだけでなく、構造の複雑化を招く誤操作防止用枠部も必要とならない。 In other words, as a lever lock mechanism, the fitting operation lever has only to be provided with a locking latching recess on one surface, and an elastic lock piece that flexes and displaces in the plate thickness direction and causes an increase in the plate thickness direction dimension. Not only is this unnecessary, but there is no need for a frame for preventing erroneous operation that leads to a complicated structure.
　従って、板状の嵌合操作レバーの構造を単純化すると同時に、当該嵌合操作レバーの板厚方向の寸法の増大を抑止して、製造コストの低減と小型化とを図ることができる。 Therefore, the structure of the plate-like fitting operation lever can be simplified, and at the same time, the increase in the dimension of the fitting operation lever in the plate thickness direction can be suppressed, and the manufacturing cost can be reduced and the size can be reduced.
　上記（２）の構成によれば、嵌合操作レバーを回動終了位置にロックするレバーロック機構として、嵌合操作レバーに形成されるロック用係止凹部は直線状に延在する溝であり、ロック用係止凹部に対応して第１のコネクタハウジングに設けられたロック用突起は直線状に延在する突条である。即ち、レバーロック機構を構成するロック用係止凹部とロック用突起の双方が、直線状の単純な構造となる。そのため、樹脂の射出成形によるこれらの機構の形成が容易になり、レバー式コネクタの生産性を向上させることができる。 According to the configuration of (2) above, as a lever lock mechanism for locking the fitting operation lever at the rotation end position, the locking recess formed on the fitting operation lever is a groove extending linearly. The locking protrusion provided on the first connector housing corresponding to the locking locking recess is a ridge extending linearly. That is, both the locking recesses and the locking protrusions constituting the lever lock mechanism have a simple linear structure. Therefore, it is easy to form these mechanisms by resin injection molding, and the productivity of the lever-type connector can be improved.
　上記（３）の構成によれば、嵌合操作レバーを回動終了位置に移動させたときに、嵌合操作レバー上のテーパ面が第１のコネクタハウジング側のロック用突起を嵌合操作レバー上のロック用係止凹部に導くため、ロック用突起とロック用係止凹部との係合を容易且つ確実にすることができる。 According to the configuration of (3) above, when the fitting operation lever is moved to the rotation end position, the tapered surface on the fitting operation lever causes the locking projection on the first connector housing side to be fitted. Since it leads to the upper locking recess, the engagement between the locking protrusion and the locking recess can be easily and reliably performed.
　本発明によるレバー式コネクタによれば、板状の嵌合操作レバーの構造を単純化すると同時に、当該嵌合操作レバーの板厚方向の寸法の増大を抑止して、製造コストの低減と小型化とを図ることができる。 According to the lever type connector of the present invention, the structure of the plate-like fitting operation lever is simplified, and at the same time, the increase in the dimension in the thickness direction of the fitting operation lever is suppressed, thereby reducing the manufacturing cost and reducing the size. Can be planned.

　ロック用係止凹部６１は、図９に示すように、嵌合操作レバー３０の一方の表面３０ａに凹んで形成されている。本実施形態の場合、ロック用係止凹部６１が装備される一方の表面３０ａは、操作部３３の裏面（図８に示す凹部３８が形成される嵌合操作レバー３０の表面とは逆側の面）である。また、ロック用係止凹部６１は、図９の矢印Ｙ４方向に延在する直線状の溝である。また、ロック用係止凹部６１に隣接する位置には、図９～図１１に示すように、テーパ面６３が設けられている。このテーパ面６３は、嵌合操作レバー３０が回動終了位置Ｐ２に向かって回動されたときの回動方向の先方側に位置している。このテーパ面６３は、後述するロック用突起６２と当接した際に、ロック用突起６２の上に乗り上がり、ロック用突起６２をロック用係止凹部６１に誘導するガイド面である。 As shown in FIG. 9, the locking engaging recess 61 is formed to be recessed in one surface 30 a of the fitting operation lever 30. In the case of this embodiment, the one surface 30a provided with the locking recess 61 is the back of the operation portion 33 (on the opposite side to the surface of the fitting operation lever 30 on which the recess 38 shown in FIG. 8 is formed).

A tapered surface 63 is provided at a position adjacent to the locking recess 61 as shown in FIGS. The taper surface 63 is located on the front side in the rotation direction when the fitting operation lever 30 is rotated toward the rotation end position P2. The tapered surface 63 is a guide surface that rides on the locking projection 62 and guides the locking projection 62 to the locking engagement recess 61 when it comes into contact with a locking projection 62 described later.
　ロック用突起６２は、嵌合操作レバー３０が回動終了位置Ｐ２に到達したときにロック用係止凹部６１に係合する突起である。ロック用突起６２は、第１のコネクタハウジング１０の端子収容部１２の上部壁１２ａの表面に突設されている。端子収容部１２の上部壁１２ａの表面は、ロック用係止凹部６１が設けられている嵌合操作レバー３０の一方の表面３０ａと対向し、レバー収容空間１５を画成した第１のコネクタハウジング１０の壁面である。 The locking protrusion 62 is a protrusion that engages with the locking engaging recess 61 when the fitting operation lever 30 reaches the rotation end position P2.

　また、本実施形態のレバー式コネクタ１の場合、嵌合操作レバー３０を回動終了位置Ｐ２にロックするレバーロック機構６０は、嵌合操作レバー３０の一方の表面３０ａに凹んで形成されたロック用係止凹部６１と、該ロック用係止凹部６１を係止するように第１のコネクタハウジング１０に設けられたロック用突起６２とで構成されている。 Further, in the case of the lever-type connector 1 of the present embodiment, the lever lock mechanism 60 that locks the fitting operation lever 30 at the rotation end position P <b> 2 is a lock formed to be recessed in one surface 30 a of the fitting operation lever 30. The locking recess 61 for locking and the locking protrusion 62 provided on the first connector housing 10 so as to lock the locking locking recess 61 are configured.
　即ち、嵌合操作レバー３０は、レバーロック機構６０としては、一方の表面３０ａにロック用係止凹部６１を設けるだけで良く、板厚方向に撓み変位して板厚方向の寸法の増大を招く弾性ロック片が不要なだけでなく、構造の複雑化を招く誤操作防止用枠部も必要とならない。 That is, the fitting operation lever 30 only needs to be provided with the locking recess 61 on one surface 30a as the lever lock mechanism 60, and is deflected and displaced in the plate thickness direction to increase the size in the plate thickness direction. Not only is the elastic locking piece unnecessary, but there is no need for an erroneous operation preventing frame that complicates the structure.
　従って、板状の嵌合操作レバー３０の構造を単純化すると同時に、当該嵌合操作レバー３０の板厚方向の寸法の増大を抑止して、製造コストの低減と小型化とを図ることができる。 Accordingly, the structure of the plate-like fitting operation lever 30 can be simplified, and at the same time, an increase in the dimension of the fitting operation lever 30 in the plate thickness direction can be suppressed, thereby reducing the manufacturing cost and reducing the size. .
　また、本実施形態のレバー式コネクタ１の場合、嵌合操作レバー３０を回動終了位置Ｐ２にロックするレバーロック機構６０として、嵌合操作レバー３０に形成されるロック用係止凹部６１は直線状に延在する溝であり、ロック用係止凹部６１に対応して第１のコネクタハウジング１０に設けられたロック用突起６２は直線状に延在する突条である。即ち、レバーロック機構６０を構成するロック用係止凹部６１とロック用突起６２の双方が、直線状の単純な構造となる。そのため、樹脂の射出成形によるこれらの機構の形成が容易になり、レバー式コネクタ１の生産性を向上させることができる。 Further, in the case of the lever-type connector 1 of the present embodiment, as the lever lock mechanism 60 that locks the fitting operation lever 30 at the rotation end position P2, the locking engaging recess 61 formed in the fitting operation lever 30 is a straight line. The locking protrusion 62 provided on the first connector housing 10 corresponding to the locking locking recess 61 is a linearly extending ridge. That is, both the locking recess 61 and the locking protrusion 62 constituting the lever lock mechanism 60 have a simple linear structure. Therefore, it becomes easy to form these mechanisms by resin injection molding, and the productivity of the lever connector 1 can be improved.
　また、本実施形態のレバー式コネクタ１の場合、嵌合操作レバー３０を回動終了位置Ｐ２に移動させたときに、嵌合操作レバー３０上のテーパ面６３が第１のコネクタハウジング１０側のロック用突起６２を嵌合操作レバー３０上のロック用係止凹部６１に導くため、ロック用突起６２とロック用係止凹部６１との係合を容易且つ確実にすることができる。 In the case of the lever-type connector 1 of the present embodiment, when the fitting operation lever 30 is moved to the rotation end position P2, the tapered surface 63 on the fitting operation lever 30 is located on the first connector housing 10 side. Since the locking projection 62 is guided to the locking latching recess 61 on the fitting operation lever 30, the locking projection 62 and the locking latching recess 61 can be easily and reliably engaged.
