本発明のレバー付きコネクタは、互いに嵌合可能な第１コネクタハウジングおよび第２コネクタハウジングと、前記第１コネクタハウジングに回動可能に取り付けられ、前記両コネクタハウジングを浅く嵌合させてから初期位置から嵌合完了位置まで回動することによって前記両コネクタハウジングを引き寄せて正規の嵌合状態に至らしめるレバーと、前記レバーの操作部に備えられて常には待機位置に保持され、前記レバーが前記嵌合完了位置に至ると検知位置への変位が許容される検知部材と、前記検知部材に設けられ、前記レバーが前記初期位置にあるときに前記レバーの操作部に設けられた第１貫通穴および前記第１コネクタハウジングに設けられた第２貫通穴を貫通して前記第１コネクタハウジングの内側に突出し、前記検知部材の変位動作および前記レバーの回動動作を制限するとともに、前記貫通穴から前記第１コネクタハウジングの内側に突出した部分に、前記第１コネクタハウジングに浅く嵌合した前記第２コネクタハウジングが当接することで外側に変位し、前記レバーの回動を許容した状態になる凸部と、を備えている。   The connector with a lever of the present invention includes a first connector housing and a second connector housing that can be fitted to each other, and is pivotally attached to the first connector housing. And a lever that pulls the two connector housings into a proper mating state by rotating from the mating position to the mating completion position, and is provided in an operating portion of the lever and is always held at a standby position, and the lever is A detection member that is allowed to be displaced to a detection position when the fitting completion position is reached, and a first through hole that is provided in the detection member and provided in the operation portion of the lever when the lever is in the initial position And the detection member protrudes inside the first connector housing through a second through hole provided in the first connector housing. The second connector housing that is shallowly fitted to the first connector housing abuts on a portion that protrudes from the through hole to the inside of the first connector housing while restricting the displacement operation and the pivoting operation of the lever. And a convex portion that is displaced outward and allows the lever to rotate.

本発明によれば、検知部材に設けられた凸部が、検知部材を待機位置に保持する保持構造およびレバーを初期位置に保持する保持構造を兼ね、またこの保持構造がレバーの操作部に設けられているから、レバーのカム板部にレバーおよび検知部材の保持構造を別々に設ける場合に比して、レバーの大型化を回避することができる。   According to the present invention, the convex portion provided on the detection member also serves as a holding structure for holding the detection member at the standby position and a holding structure for holding the lever at the initial position, and this holding structure is provided at the operation portion of the lever. Therefore, it is possible to avoid an increase in the size of the lever as compared with the case where the holding structure for the lever and the detection member is separately provided on the cam plate portion of the lever.

A locking claw 53 that protrudes forward is provided at the tip (rise end) of the arm portion 52.

本体部５１の後端部には、検知部材５０を待機位置から検知位置に押し込む際に押圧する押圧操作部５４が設けられている。押圧操作部５４は、図５に示すように、側方から見ると略方形断面を有する角筒状をなし、図３および図４に示すように、本体部５１から左右両側に突出している。押圧操作部５４は、梁部２７とベース壁部２８との間に配されて上下方向の変位が制限される。   At the rear end portion of the main body portion 51, a pressing operation portion 54 that is pressed when the detection member 50 is pushed from the standby position to the detection position is provided. As shown in FIG. 5, the pressing operation portion 54 has a rectangular tube shape having a substantially square cross section when viewed from the side, and protrudes from the main body portion 51 to the left and right sides as shown in FIGS. 3 and 4. The pressing operation part 54 is disposed between the beam part 27 and the base wall part 28, and the displacement in the vertical direction is limited.

そして、検知部材５０には、図５に示すように、レバー２０が初期位置にあるときに第１貫通穴３１および第２貫通穴１６を貫通して第１コネクタハウジング１０の内側に突出し、検知部材５０の変位動作およびレバー２０の回動動作を制限する凸部５５が設けられている。凸部５５は、第２貫通穴１６から第１コネクタハウジング１０の内側に突出した部分に、第２コネクタハウジング４０の第１解除突起４２が当接することで、図６に示すように、外側に変位し、レバー２０の回動を許容した状態になる。   Then, as shown in FIG. 5, the detection member 50 protrudes inside the first connector housing 10 through the first through hole 31 and the second through hole 16 when the lever 20 is in the initial position. A convex portion 55 that restricts the displacement operation of the member 50 and the rotation operation of the lever 20 is provided. As shown in FIG. 6, the convex portion 55 is formed on the outside as a result of the first release protrusion 42 of the second connector housing 40 coming into contact with a portion protruding from the second through hole 16 to the inside of the first connector housing 10. Displacement and the lever 20 are allowed to rotate.

凸部５５は、本体部５１の下面のうち前端寄りの位置に突設されている。凸部５５は、図４に示すように、本体部５１と同等の幅寸法を有して本体部５１の下面から垂下する垂下部５６と、垂下部５６の下端部に設けられて、第２コネクタハウジング４０に設けられた第１解除突起４２が当接する当接部５７とを有している。当接部５７は、垂下部５６から左右両側に突出し、前方から見ると左右方向に細長い長方形状をなしている。   The convex portion 55 projects from the lower surface of the main body portion 51 at a position near the front end. As shown in FIG. 4, the convex portion 55 has a width dimension equivalent to that of the main body portion 51 and is suspended from the lower surface of the main body portion 51, and is provided at the lower end portion of the drooping portion 56. And a contact portion 57 with which the first release protrusion 42 provided on the connector housing 40 abuts. The contact portion 57 protrudes from the hanging portion 56 to the left and right sides, and has a rectangular shape elongated in the left-right direction when viewed from the front.

レバー２０が初期位置にあるときには、図５に示すように、垂下部５６が第１貫通穴３１内に配され、当接部５７が第２貫通穴１６内から第１コネクタハウジング１０の内側にわたって配される。この状態において、レバー２０を嵌合完了位置へ回動変位させようとした場合には、凸部５５の前面が第２貫通穴１６の前面に当接し、レバー２０の回動変位が行われないようになっている。   When the lever 20 is in the initial position, as shown in FIG. 5, the drooping portion 56 is disposed in the first through hole 31, and the contact portion 57 extends from the second through hole 16 to the inside of the first connector housing 10. Arranged. In this state, when the lever 20 is to be rotated and displaced to the fitting completion position, the front surface of the convex portion 55 comes into contact with the front surface of the second through hole 16 and the lever 20 is not rotationally displaced. It is like that.

凸部５５の下端部には、図５に示すように、レバー２０の回動方向に沿う傾斜（前方に向かって次第に上る傾斜）をなす傾斜面５８が設けられている。傾斜面５８は、当接部５７の前面側に形成され、下端の角部を斜めに切り欠いた形態とされている。傾斜面５８は、当接部５７のうちレバー２０が初期位置にあるときに第２貫通穴１６から第１コネクタハウジング１０の内側に突出する部分であって第２コネクタハウジング４０の第１解除突起４２が当接することで外側に変位した際に第２貫通穴１６内に配される部分に形成されている。   As shown in FIG. 5, an inclined surface 58 is provided at the lower end portion of the convex portion 55. The inclined surface 58 forms an inclination along the rotation direction of the lever 20 (inclination gradually rising toward the front). The inclined surface 58 is formed on the front surface side of the contact portion 57, and has a form in which a corner portion at the lower end is cut out obliquely. The inclined surface 58 is a portion of the contact portion 57 that protrudes from the second through hole 16 to the inside of the first connector housing 10 when the lever 20 is in the initial position, and is a first release protrusion of the second connector housing 40. It is formed in the part arranged in the 2nd through-hole 16 when 42 is displaced outside by contact | abutting.

次に、レバー付きコネクタＣの嵌合作業の一例について説明する。
レバー付きコネクタＣの嵌合前においては、図１に示すように、第１コネクタハウジング１０において検知部材５０を待機位置に保持するとともにレバー２０を初期位置に保持する。この状態では、検知部材５０は、押圧操作部５４が梁部２７とベース壁部２８とに挟まれて上下方向の変位を制限され、係止爪５３が第１ロック部３３に係止して前方への変位が制限され、凸部５５が第１貫通穴３１を貫通することで後方への変位が制限されている。また、レバー２０は、検知部材５０の凸部５５が第２貫通穴１６を貫通することで、初期位置から嵌合完了位置へ向かう回動変位が制限されている。 Next, an example of the fitting operation of the connector C with lever will be described.
Before the connector C with a lever is fitted, the detection member 50 is held at the standby position and the lever 20 is held at the initial position in the first connector housing 10 as shown in FIG. In this state, in the detection member 50, the pressing operation portion 54 is sandwiched between the beam portion 27 and the base wall portion 28 and the vertical displacement is restricted, and the locking claw 53 is locked to the first lock portion 33. The forward displacement is restricted, and the rearward displacement is restricted when the convex portion 55 penetrates the first through hole 31. Further, the lever 20 is limited in rotational displacement from the initial position to the fitting completion position because the convex portion 55 of the detection member 50 passes through the second through hole 16.

次に、両コネクタハウジング１０，４０を浅く嵌合する。すると、第２コネクタハウジング４０のカムピン４８が第１コネクタハウジング１０のカム溝の入口に進入する。また、図６に示すように、第２コネクタハウジング４０の第１解除突起４２が第１コネクタハウジング１０の溝部１５を通って奥側に進入し、やがて凸部５５の傾斜面５８に当接して凸部５５を上方（外側）へ変位させレバー２０の係止状態を解除する。この際、検知部材５０は、本体部５１の前側部分が上方に弾性変位し、押圧操作部５４が梁部２７とベース壁部２８とに挟まれ、凸部５５が第１貫通穴３１から下方に突出した状態となっている。   Next, both connector housings 10 and 40 are fitted shallowly. Then, the cam pin 48 of the second connector housing 40 enters the inlet of the cam groove of the first connector housing 10. Further, as shown in FIG. 6, the first release protrusion 42 of the second connector housing 40 enters the back side through the groove portion 15 of the first connector housing 10, and eventually comes into contact with the inclined surface 58 of the convex portion 55. The protrusion 55 is displaced upward (outside) to release the locked state of the lever 20. At this time, in the detection member 50, the front portion of the main body 51 is elastically displaced upward, the pressing operation portion 54 is sandwiched between the beam portion 27 and the base wall portion 28, and the convex portion 55 is downward from the first through hole 31. It is in a state protruding.

次いで、レバー２０を初期位置から嵌合完了位置に回動させる。操作部２２を上方に移動させると、第２貫通穴１６の上端に凸部５５の傾斜面５８が沿うようにして、レバー２０はスムーズに回動する。また、凸部５５が第１解除突起４２から離れることで、検知部材５０の姿勢は弾性復帰する。そして、レバー２０の回動に伴って、カムピン４８がカム溝に沿って変位し、両コネクタハウジング１０，４０の嵌合が進む。やがて、レバー２０が嵌合完了位置に近づくと、第１ロック部３３が第２解除突起４５に当接して弾性壁部２９が後方へ弾性変形し、レバー２０が嵌合完了位置に至ると、図７に示すように、第１ロック部３３が第２解除突起４５および第２ロック部４４の下方に入り込んで弾性壁部２９が弾性復帰し、第１ロック部３３と第２ロック部４４とが係止状態になる。これにより、第１コネクタハウジング１０と第２コネクタハウジング４０とが離間不能に保持される。   Next, the lever 20 is rotated from the initial position to the fitting completion position. When the operating portion 22 is moved upward, the lever 20 smoothly rotates so that the inclined surface 58 of the convex portion 55 is along the upper end of the second through hole 16. Moreover, the attitude | position of the detection member 50 returns elastically because the convex part 55 leaves | separates from the 1st cancellation | release protrusion 42. FIG. As the lever 20 rotates, the cam pin 48 is displaced along the cam groove, and the fitting of the connector housings 10 and 40 proceeds. Eventually, when the lever 20 approaches the fitting completion position, the first lock portion 33 comes into contact with the second release protrusion 45 and the elastic wall portion 29 is elastically deformed backward, and when the lever 20 reaches the fitting completion position, As shown in FIG. 7, the first lock portion 33 enters below the second release protrusion 45 and the second lock portion 44, and the elastic wall portion 29 is elastically restored, so that the first lock portion 33, the second lock portion 44, Is locked. Thereby, the 1st connector housing 10 and the 2nd connector housing 40 are held so that separation is impossible.

また、同時に、第１ロック部３３の上方の窓部３６に、第２コネクタハウジング４０の第２解除突起４５が突入し、係止爪５３が第２解除突起４５によって後方に押されてアーム部５２が後方へ弾性変位し、検知部材５０の係止状態が解除される。   At the same time, the second release projection 45 of the second connector housing 40 enters the window portion 36 above the first lock portion 33, and the locking claw 53 is pushed rearward by the second release projection 45 so that the arm portion. 52 is elastically displaced rearward and the locked state of the detection member 50 is released.

次に、検知部材５０を検知位置に押し込む。検知部材５０の押圧操作部５４を下方へ押すと、係止爪５３が第２解除突起４５を乗り越えて第１ロック部３３の押し込み誘導面図８に示すように、３４に至り、その傾斜によって第１ロック部３３を乗り越え、図９に示すように、検知部材５０が検知位置に至る。そして、検知部材５０は、多機能部４６の前面に突き当たることでそれ以上の移動が制限され、係止爪５３が第１ロック部３３の下方に至り、押圧操作部５４がベース壁部２８と天井壁部３５との間に挟まれた状態になる。なお、凸部５５は、第１貫通穴３１内を下方に移動している。   Next, the detection member 50 is pushed into the detection position. When the pressing operation portion 54 of the detection member 50 is pushed downward, the locking claw 53 gets over the second release protrusion 45 and reaches the push-in guide surface of the first lock portion 33 as shown in FIG. As shown in FIG. 9, the detection member 50 reaches the detection position over the first lock portion 33. Further, the detection member 50 is abutted against the front surface of the multi-function part 46, so that further movement is restricted, the locking claw 53 reaches below the first lock part 33, and the pressing operation part 54 is connected to the base wall part 28. It is in a state of being sandwiched between the ceiling wall portion 35. The convex portion 55 moves downward in the first through hole 31.

ここで、レバー２０が嵌合完了位置に至っていない場合には、係止爪５３が係止解除方向に押されずに第１ロック部３３に係止したままとなっているので、検知部材５０を押し込もうとしてもできない。これにより、作業者は、レバー２０が嵌合完了位置に至っていない、すなわち両コネクタハウジング１０，４０の嵌合が正常に完了していない（半嵌合状態である）ことを知ることができる。そして、作業者が、レバー２０を確実に嵌合完了位置まで回動させることで、両コネクタハウジング１０，４０は、確実に正規の嵌合状態とされる。   Here, when the lever 20 has not reached the fitting completion position, the locking claw 53 remains locked to the first lock portion 33 without being pushed in the locking release direction. You can't push it in. Thereby, the operator can know that the lever 20 has not reached the fitting completion position, that is, the fitting of the two connector housings 10 and 40 has not been completed normally (in a semi-fitted state). Then, when the operator reliably rotates the lever 20 to the fitting completion position, the two connector housings 10 and 40 are surely brought into a proper fitting state.

次に、上記のように構成された本実施例の作用および効果について説明する。
本実施例のレバー付きコネクタＣは、互いに嵌合可能な第１コネクタハウジング１０および第２コネクタハウジング４０を備え、第１コネクタハウジング１０には、両コネクタハウジング１０，４０を浅く嵌合させてから初期位置から嵌合完了位置まで回動することによって両コネクタハウジング１０，４０を引き寄せて正規の嵌合状態に至らしめるレバー２０が回動可能に取り付けられ、レバー２０の操作部２２には、常には待機位置に保持され、レバー２０が嵌合完了位置に至ると検知位置への変位が許容される検知部材５０が備えられている。そして、検知部材５０には、レバー２０が初期位置にあるときにレバー２０の操作部２２に設けられた第１貫通穴３１および第１コネクタハウジング１０に設けられた第２貫通穴１６を貫通して第１コネクタハウジング１０の内側に突出し、検知部材５０の変位動作およびレバー２０の回動動作を制限するとともに、第２貫通穴１６から第１コネクタハウジング１０の内側に突出した部分に、第１コネクタハウジング１０に浅く嵌合した第２コネクタハウジング４０が当接することで外側に変位し、レバー２０の回動を許容した状態になる凸部５５が設けられている。 Next, the operation and effect of the present embodiment configured as described above will be described.
The connector C with a lever of the present embodiment includes a first connector housing 10 and a second connector housing 40 that can be fitted to each other, and after the two connector housings 10 and 40 are shallowly fitted in the first connector housing 10. A lever 20 that pivots from the initial position to the mating completion position and pulls the connector housings 10 and 40 to reach a proper mating state is pivotally attached. Is held at the standby position, and a detection member 50 is provided that is allowed to be displaced to the detection position when the lever 20 reaches the fitting completion position. The detection member 50 passes through the first through hole 31 provided in the operation portion 22 of the lever 20 and the second through hole 16 provided in the first connector housing 10 when the lever 20 is in the initial position. Projecting inside the first connector housing 10 to restrict the displacement operation of the detection member 50 and the rotation operation of the lever 20, and to the portion projecting from the second through hole 16 to the inside of the first connector housing 10, A convex portion 55 is provided that is displaced outwardly when the second connector housing 40 that is shallowly fitted to the connector housing 10 is in contact with the connector housing 10 and that allows the lever 20 to rotate.

この構成によれば、検知部材５０に設けられた凸部５５が、検知部材５０を待機位置に保持する保持構造およびレバー２０を初期位置に保持する保持構造を兼ね、またこの保持構造がレバー２０の操作部２２に設けられているから、レバーのカム板部にレバーおよび検知部材の保持構造を別々に設ける場合に比して、レバー２０の大型化を回避することができる。   According to this configuration, the convex portion 55 provided on the detection member 50 serves as a holding structure for holding the detection member 50 in the standby position and a holding structure for holding the lever 20 in the initial position. Therefore, it is possible to avoid an increase in the size of the lever 20 as compared with the case where the lever and the detection member holding structure are separately provided on the cam plate portion of the lever.

また、凸部５５のうちレバー２０が初期位置にあるときに第２貫通穴１６から第１コネクタハウジング１０の内側に突出する部分であって第２コネクタハウジング４０が当接することで外側に変位した際に第２貫通穴１６内に配される部分には、レバー２０の回動方向に沿う傾斜をなす傾斜面５８が設けられている。
この構成によれば、レバー２０を初期位置から嵌合完了位置に向けて回動させる際に、凸部５５の傾斜面５８によって凸部５５が第２貫通穴１６から容易に外側に出るから、レバー２０をスムーズに回動することができる。 In addition, when the lever 20 is in the initial position, the convex portion 55 is a portion that protrudes from the second through hole 16 to the inside of the first connector housing 10 and is displaced outward by the second connector housing 40 coming into contact therewith. At the same time, an inclined surface 58 that is inclined along the rotation direction of the lever 20 is provided in a portion disposed in the second through hole 16.
According to this configuration, when the lever 20 is rotated from the initial position toward the fitting completion position, the convex portion 55 easily comes out of the second through hole 16 by the inclined surface 58 of the convex portion 55. The lever 20 can be smoothly rotated.
