 上記のコネクタでは、正規嵌合状態の第1ハウジングと第2ハウジングを離脱する際に、ロックアームによるロックを解除する作業として、まず、検知部材を検知位置から初期位置へ移動させ、その後、検知部材から手を離してロック解除操作部を操作するという、ツーアクションの作業が必要であった。そのため、作業性の点で改善が望まれる。
 本発明は上記のような事情に基づいて完成されたものであって、ロックアームによるロックを解除する際の作業性向上を図ることを目的とする。
In the above connector, when releasing the first housing and the second housing in the normal fitting state, as a work for releasing the lock by the lock arm, first, the detection member is moved from the detection position to the initial position, and then the detection is performed. A two-action operation was required in which the hand was released from the member and the unlocking operation unit was operated. Therefore, improvement is desired in terms of workability.
The present invention has been completed based on the above circumstances, and an object thereof is to improve workability when releasing the lock by the lock arm.
 上記の目的を達成するための手段として、本発明は、
 第1ハウジングと、
 ロック用受け部が形成された第2ハウジングと、
 前記第1ハウジングに形成され、前記ロック用受け部と係止することで前記第1ハウジングと前記第2ハウジングを嵌合状態にロックするロックアームと、
 前記第1ハウジングに、初期位置を通過する経路に沿って検知位置とロック解除位置との間で移動し得るように取り付けられ、前記第1ハウジングと前記第2ハウジングの嵌合過程では検知位置への移動を規制された状態で初期位置に保持され、前記第1ハウジングと前記第2ハウジングが正規嵌合した状態では検知位置とロック解除位置との間の移動を許容される検知部材と、
 前記検知部材に形成され、前記第1ハウジングと前記第2ハウジングが正規嵌合した状態において、前記検知部材が初期位置からロック解除位置へ移動する過程で前記ロックアームをロック解除方向へ弾性撓みさせるロック解除部とを備えていることを特徴とするコネクタ。
As means for achieving the above object, the present invention provides:
A first housing;
A second housing having a receiving portion for locking;
A lock arm formed on the first housing and locking the first housing and the second housing in a fitted state by engaging with the lock receiving portion;
The first housing is attached so as to be movable between a detection position and an unlock position along a path passing through an initial position, and is moved to the detection position in the fitting process of the first housing and the second housing. A detection member that is held at an initial position in a state in which movement of the first housing and the second housing is normally fitted, and is allowed to move between a detection position and an unlock position when the first housing and the second housing are properly fitted,
The lock arm is elastically bent in the unlocking direction when the detection member is moved from the initial position to the unlocking position when the first housing and the second housing are properly fitted to each other. A connector comprising a lock release portion.
 本発明によれば、正規嵌合状態の第1ハウジングと第2ハウジングを離脱する際には、検知位置にある検知部材を、バネ部材の付勢に抗して押し動かし、初期位置を通過させてロック解除位置まで移動させる。検知部材が初期位置からロック解除位置へ移動する過程では、ロック解除部がロックアームをロック解除方向へ弾性撓みさせるので、検知部材をロック解除位置へ移動させた状態のまま、両ハウジングを引き離せばよい。本発明では、ロックアームによるロックを解除する際には、検知部材を検知位置からロック解除位置まで押し動かすというワンアクションの操作だけで済む。したがって、検知部材を検知位置から初期位置へ移動させる作業と、その後に、検知部材から手を離してロックアームをロック解除操作する作業をツーアクションで別々に行う場合に比べると、本発明のコネクタは作業性に優れている。 According to the present invention, when separating the first housing and the second housing in the normal fitting state, the detection member at the detection position is pushed against the bias of the spring member to pass the initial position. To the unlock position. In the process in which the detection member moves from the initial position to the lock release position, the lock release portion elastically bends the lock arm in the lock release direction, so that both housings can be pulled apart while the detection member is moved to the lock release position. That's fine. In the present invention, when releasing the lock by the lock arm, only one action of pushing the detection member from the detection position to the lock release position is sufficient. Therefore, the connector of the present invention is compared with the case where the operation of moving the detection member from the detection position to the initial position and the operation of releasing the lock arm by releasing the hand from the detection member are separately performed in two actions. Is excellent in workability.

The first stopper 16 is a means for holding the detection member 40 at the initial position in a state where the detection member 40 described later is biased toward the detection position by the spring member 56.
 <周壁部17>
 図1に示すように、周壁部17は、端子収容部11の下面と対向する下壁部18と、端子収容部11の側面と対向する左右一対の側壁部19と、両側壁部19の上端縁(下壁部18とは反対側の端縁)から内側へ片持ち状に張り出す左右一対の張出部20とから構成されている。端子収容部11の外周面と周壁部17の内周面との間の空間は、第2ハウジング60のフード部62を嵌入させるための嵌合空間21となっている。嵌合空間21は、第1ハウジング10の前方(正面側)に開放されている。
<Surrounding wall part 17>
As shown in FIG. 1, the peripheral wall portion 17 includes a lower wall portion 18 that faces the lower surface of the terminal housing portion 11, a pair of left and right side wall portions 19 that face the side surfaces of the terminal housing portion 11, and upper ends of both side wall portions 19. It comprises a pair of left and right projecting portions 20 that project in a cantilevered manner from the edge (the end edge opposite to the lower wall portion 18). A space between the outer peripheral surface of the terminal accommodating portion 11 and the inner peripheral surface of the peripheral wall portion 17 is a fitting space 21 for fitting the hood portion 62 of the second housing 60. The fitting space 21 is open to the front (front side) of the first housing 10.
 周壁部17は、周方向における一部(上面部)が切欠された形態であり、この切欠された部分は、嵌合空間21及び検知部材40を周壁部17の外周側(上方)へ露出させる開口部22となっている。図8に示すように、前後方向(両ハウジング10,60の嵌合方向と平行な方向)における開口部22の形成範囲は、周壁部17の前端から後端に至る全領域であり、開口部22は第1ハウジング10の前方へ開放されている。図13に示すように、周壁部17の前端は、前後方向において端子収容部11の前端と同じ位置にある。周壁部17の後端は、端子収容部11の前後方向における略中央位置において、端子収容部11の外周に連なっている。つまり、周壁部17は、前方へ片持ち状に延出した形態である。 The peripheral wall portion 17 has a form in which a part (upper surface portion) in the circumferential direction is cut out, and the cut-out portion exposes the fitting space 21 and the detection member 40 to the outer peripheral side (upward) of the peripheral wall portion 17. An opening 22 is formed. As shown in FIG. 8, the formation range of the opening 22 in the front-rear direction (the direction parallel to the fitting direction of both housings 10 and 60) is the entire region from the front end to the rear end of the peripheral wall portion 17. 22 is open to the front of the first housing 10. As shown in FIG. 13, the front end of the peripheral wall portion 17 is at the same position as the front end of the terminal accommodating portion 11 in the front-rear direction. The rear end of the peripheral wall portion 17 continues to the outer periphery of the terminal accommodating portion 11 at a substantially central position in the front-rear direction of the terminal accommodating portion 11. That is, the peripheral wall portion 17 has a form that extends forward in a cantilevered manner.
 図1,6に示すように、周壁部17には、左右対称な一対のリブ23が形成されている。リブ23は、張出部20の延出端縁、つまり、開口部22の開口領域における左右両側縁に沿って、前後方向に直線状に延びた形態である。リブ23は、周壁部17の外周側へ突出した形態である。このリブ23は、周壁部17が開口部22の開口幅を変化させるように変形するのを規制する機能と、検知部材40がロック解除位置と検知位置との間で移動する際のガイドとしての機能を兼ね備えている。 As shown in FIGS. 1 and 6, a pair of symmetrical ribs 23 are formed on the peripheral wall portion 17. The rib 23 has a form extending linearly in the front-rear direction along the extended end edge of the overhanging portion 20, that is, the left and right side edges in the opening region of the opening 22. The rib 23 has a shape protruding toward the outer peripheral side of the peripheral wall portion 17. The rib 23 serves as a guide for restricting the deformation of the peripheral wall 17 so as to change the opening width of the opening 22 and as a guide when the detection member 40 moves between the unlock position and the detection position. It has a function.
 図1,6に示すように、周壁部17には、張出部20の前端縁(正面側の端縁)から内周側(嵌合空間21側)へ突出した形態の覆い部24が一体形成されている。覆い部24は、左右対称に一対設けられている。周方向における覆い部24の形成領域は、側壁部19の上端部から、張出部20の全領域に亘る範囲である。第1ハウジング10の正面側から見たとき、つまり両ハウジング10,60の嵌合方向と平行に投影した仮想投影面(図示省略)上において、覆い部24は、検知部材40の前面壁50と対応する形状・配置となっている。 As shown in FIGS. 1 and 6, the peripheral wall portion 17 is integrally provided with a cover portion 24 that protrudes from the front end edge (front end edge) of the overhang portion 20 toward the inner peripheral side (fitting space 21 side). Is formed. A pair of cover portions 24 are provided symmetrically. The formation region of the cover portion 24 in the circumferential direction is a range extending from the upper end portion of the side wall portion 19 to the entire region of the overhang portion 20. When viewed from the front side of the first housing 10, that is, on a virtual projection plane (not shown) projected in parallel with the fitting direction of the two housings 10, 60, the cover 24 is connected to the front wall 50 of the detection member 40. Corresponding shape and arrangement.
 <ロックアーム25>
 図6~8に示すように、端子収容部11を構成するハウジング本体12には、ロックアーム25が一体に形成されている。ロックアーム25は、端子収容部11の上面15から突出した左右一対の脚部26と、脚部26から前方及び後方へ端子収容部11の外面に沿うように片持ち状に延出した略平板状のアーム部27とを一体に形成したものである。ロックアーム25は、嵌合空間21内において、端子収容部11の上面15と略平行に対向するように配されている。ロックアーム25は、常にはロック姿勢(図7,12,14~17,19を参照)に保たれているが、脚部26を支点としてシーソー状に弾性変形してロック解除姿勢(図13,18,20を参照)をとり得るようになっている。
<Lock arm 25>
As shown in FIGS. 6 to 8, a lock arm 25 is formed integrally with the housing main body 12 constituting the terminal accommodating portion 11. The lock arm 25 includes a pair of left and right leg portions 26 projecting from the upper surface 15 of the terminal accommodating portion 11, and a substantially flat plate extending in a cantilever manner from the leg portion 26 forward and rearward along the outer surface of the terminal accommodating portion 11. The arm portion 27 is integrally formed. The lock arm 25 is disposed in the fitting space 21 so as to face the upper surface 15 of the terminal accommodating portion 11 substantially in parallel. The lock arm 25 is always maintained in a locked posture (see FIGS. 7, 12, 14 to 17, and 19), but is elastically deformed into a seesaw shape with the leg portion 26 as a fulcrum (see FIG. 13, FIG. 18 and 20).
 ロックアーム25の前端部(第1ハウジング10の正面側の端部)には、下方(端子収容部11)に向かって突出するロック突起28が形成されている。ロック突起28の幅方向(ロックアーム25の弾性変位方向及び両ハウジング10,60の嵌合方向の両方向と交差する方向)における形成範囲は、ロックアーム25の中央部のみである。図2に示すように、ロックアーム25の前端部には、ロック突起28が形成されていない幅方向両端部を切欠した形態の左右一対の切欠部29が形成されている。そして、ロックアーム25の前端部のうち両切欠部29の間においてロック突起28が形成されている部分は、幅狭部30となっている。 At the front end of the lock arm 25 (the end on the front side of the first housing 10), there is formed a lock projection 28 that protrudes downward (the terminal accommodating portion 11). The formation range in the width direction of the lock protrusion 28 (the direction of elastic displacement of the lock arm 25 and the direction intersecting both the fitting directions of the housings 10 and 60) is only the central portion of the lock arm 25. As shown in FIG. 2, a pair of left and right cutout portions 29 are formed at the front end portion of the lock arm 25 in a form in which both end portions in the width direction where the lock protrusions 28 are not formed are cut out. A portion of the front end portion of the lock arm 25 where the lock protrusions 28 are formed between the notches 29 is a narrow portion 30.
 図6~8に示すように、ロックアーム25の後端部には、端子収容部11から遠ざかる方向(ロック突起28とは反対側)へ突出した形態の受圧部31が形成されている。端子収容部11の上面15とロックアーム25とが対向する方向(以下、「高さ方向」という)において、端子収容部11の上面15を基準とする受圧部31の外面31Sの高さは、アーム部27の外面よりも高い。つまり、受圧部31の外面31Sは、ロックアーム25のうち端子収容部11の上面15から最も遠い位置(最も高い位置)に位置する。また、受圧部31の外面31Sは、周壁部17のリブ23の上端縁よりも高い位置にある。 As shown in FIGS. 6 to 8, a pressure receiving portion 31 is formed at the rear end portion of the lock arm 25 so as to protrude in a direction away from the terminal accommodating portion 11 (on the side opposite to the lock projection 28). In the direction in which the upper surface 15 of the terminal accommodating portion 11 and the lock arm 25 face each other (hereinafter referred to as “height direction”), the height of the outer surface 31S of the pressure receiving portion 31 with respect to the upper surface 15 of the terminal accommodating portion 11 is It is higher than the outer surface of the arm part 27. That is, the outer surface 31 </ b> S of the pressure receiving portion 31 is located at a position (the highest position) farthest from the upper surface 15 of the terminal accommodating portion 11 in the lock arm 25. Further, the outer surface 31 </ b> S of the pressure receiving portion 31 is at a position higher than the upper end edge of the rib 23 of the peripheral wall portion 17.
 受圧部31には、その上面31S及び後面31Rに対して斜めをなすテーパ状の受圧面33が形成されている。この受圧面33は、ロックアーム25がロック姿勢とロック解除姿勢との間で弾性撓みする方向、及び後述する検知部材40が検知位置とロック解除位置との間で直線移動するときの移動方向の両方向に対して傾斜した面となっている。つまり、受圧面33は、斜め上後方に面している。この受圧面33は、後述する検知部材40のロック解除部57の押圧縁部58に押されることで、ロックアーム25をロック姿勢からロック解除姿勢へ変位させる。 The pressure receiving portion 31 is formed with a tapered pressure receiving surface 33 that is inclined with respect to the upper surface 31S and the rear surface 31R. The pressure receiving surface 33 is provided in a direction in which the lock arm 25 is elastically bent between the locked posture and the unlocked posture, and in a moving direction when a detection member 40 described later moves linearly between the detected position and the unlocked position. The surface is inclined with respect to both directions. That is, the pressure receiving surface 33 faces obliquely upward and rearward. The pressure receiving surface 33 is pushed by a pressing edge portion 58 of a lock release portion 57 of the detection member 40 described later, thereby displacing the lock arm 25 from the lock posture to the lock release posture.
 アーム部27の上面には、後述する検知部材40が初期位置又はロック解除位置から検知位置側へ移動したときに、検知位置に到達した検知部材40の移動を規制するための第2ストッパ32が突出形成されている。端子収容部11の上面15を基準とする第2ストッパ32の外面(上面)の位置は、受圧部31の外面31Sよりも低いが、リブ23の上端縁よりも高い位置である。第2ストッパ32の幅方向における形成範囲は、ロックアーム25の中央部のみであり、第2ストッパ32の幅寸法は、幅狭部30の幅寸法よりも小さい。 A second stopper 32 for restricting the movement of the detection member 40 that has reached the detection position when a detection member 40 described later moves from the initial position or the unlocking position to the detection position side on the upper surface of the arm portion 27. Protrusions are formed. The position of the outer surface (upper surface) of the second stopper 32 with respect to the upper surface 15 of the terminal accommodating portion 11 is lower than the outer surface 31S of the pressure receiving portion 31 but higher than the upper end edge of the rib 23. The formation range of the second stopper 32 in the width direction is only the central portion of the lock arm 25, and the width dimension of the second stopper 32 is smaller than the width dimension of the narrow portion 30.
 <検知部材40>
 図9~11に示すように、検知部材40は、検知部材40の外面40Sを構成する枠部41と、連結部54とを一体に形成して構成されている。枠部41は、長さ方向を幅方向に向けた前枠42と、前枠42の左右両端から後方へ延出する左右対称な一対の側枠43とを備え構成されている。端子収容部11の上面15を基準とする高さ方向において、前枠42及び側枠43の上面は、検知部材40のうち最も高い位置に配された外面40Sとなっている。この外面40Sの高さは、ロックアーム25の外面31Sとほぼ同じ高さである。
<Detection member 40>
As shown in FIGS. 9 to 11, the detection member 40 is configured by integrally forming a frame portion 41 constituting the outer surface 40S of the detection member 40 and a connecting portion 54. The frame portion 41 includes a front frame 42 whose length direction is directed in the width direction, and a pair of left and right symmetrical side frames 43 that extend rearward from the left and right ends of the front frame 42. In the height direction with respect to the upper surface 15 of the terminal accommodating portion 11, the upper surfaces of the front frame 42 and the side frame 43 are outer surfaces 40 </ b> S arranged at the highest position among the detection members 40. The height of the outer surface 40S is substantially the same height as the outer surface 31S of the lock arm 25.
 枠部41は、前枠42と側枠43の他に、左右両側枠43の後端部における上端同士を連結するロック解除部57とを備えて構成されている。ロック解除部57は、左右方向に細長く延びた形態である。ロック解除部57の上面は、側枠43の上面に対して面一状に繋がっていて外面40Sを構成する。また、ロック解除部57の後面は、側枠43の後面と面一状に繋がっていて、検知部材40の後端面を構成する。ロック解除部57のうち、その前面と下面とを略直角に繋ぐ角縁部は、斜め下前方に突出した形態の押圧縁部58となっている。この押圧縁部58は、ロックアーム25の受圧面33に対して斜め上後方から押圧力を付与することで、ロックアーム25をロック姿勢からロック解除姿勢へ弾性撓みさせる(図13を参照)。 The frame portion 41 is configured to include, in addition to the front frame 42 and the side frame 43, a lock release portion 57 that connects upper ends of the rear end portions of the left and right side frames 43. The unlocking portion 57 has a shape that is elongated in the left-right direction. The upper surface of the unlocking portion 57 is connected to the upper surface of the side frame 43 so as to form the outer surface 40S. In addition, the rear surface of the unlocking portion 57 is connected to the rear surface of the side frame 43 so as to form the rear end surface of the detection member 40. Of the unlocking portion 57, the corner edge portion that connects the front surface and the lower surface at a substantially right angle is a pressing edge portion 58 that protrudes obliquely downward and forward. The pressing edge 58 elastically deflects the lock arm 25 from the locked posture to the unlocked posture by applying a pressing force to the pressure receiving surface 33 of the lock arm 25 from obliquely upward and rearward (see FIG. 13).
 図13に示すように、前枠42は、端子収容部11の上面15と略平行な略平板状をなす。図11に示すように、前枠42の前端縁は、検知部材40の最も前端に位置し、左右方向にほぼ真っ直ぐに延びている。前枠42の前後方向の寸法は、幅方向中央部で小さく、幅方向における両端側で大きくなっている。そして、前枠42の幅方向両端側部分において後方へ張り出している部分は、一対の補強部44となっている。この補強部44は、側枠43の前端部に連なっており、前枠42の強度を高めるための手段として機能する。また、一対の補強部44の幅方向における形成領域は、ロックアーム25の切欠部29と対応する領域、つまり幅狭部30と非対応の範囲である。 As shown in FIG. 13, the front frame 42 has a substantially flat plate shape that is substantially parallel to the upper surface 15 of the terminal accommodating portion 11. As shown in FIG. 11, the front end edge of the front frame 42 is located at the foremost end of the detection member 40 and extends substantially straight in the left-right direction. The size of the front frame 42 in the front-rear direction is small at the center in the width direction and is large at both ends in the width direction. And the part which protrudes back in the width direction both ends side part of the front frame 42 is a pair of reinforcement part 44. As shown in FIG. The reinforcing portion 44 is connected to the front end portion of the side frame 43 and functions as a means for increasing the strength of the front frame 42. The formation region in the width direction of the pair of reinforcing portions 44 is a region corresponding to the notch 29 of the lock arm 25, that is, a range not corresponding to the narrow portion 30.
 図3,16に示すように、前枠42のうち一対の補強部44で挟まれた中央部分は、検知部材40がバネ部材56の付勢によって初期位置から検知位置側へ押し動かされたときに、第2ストッパ32に当接することで検知部材40を検知位置に保持するための手段として機能する。また、図16に示すように、前枠42の全幅領域は、ロック姿勢のロックアーム25が、ロック解除姿勢へ弾性変位するのを規制するためのロック解除規制手段として機能する。 As shown in FIGS. 3 and 16, when the detection member 40 is pushed from the initial position to the detection position side by the urging of the spring member 56, the center portion sandwiched between the pair of reinforcing portions 44 in the front frame 42 is moved. Furthermore, it functions as a means for holding the detection member 40 at the detection position by contacting the second stopper 32. Further, as shown in FIG. 16, the full width region of the front frame 42 functions as a lock release restricting means for restricting the lock arm 25 in the lock posture from being elastically displaced to the lock release posture.
 図9,10,17に示すように、側枠43は、左右一対のバネ収容部45を備える。バネ収容部45は、軸線を前後方向に向けて後端が後面壁47で部分的に塞がれた円筒部46と、円筒部46の前端に面一状に連なる円弧状部48とから構成される。円弧状部48の周方向における形成領域は、円筒部46を上下左右の4つの四半円弧領域に仮想的に分割したときに、上部の四半円弧領域と、2つの側部のうち幅方向において外側に位置する側部の四半円弧領域とに対応する範囲である。 As shown in FIGS. 9, 10, and 17, the side frame 43 includes a pair of left and right spring accommodating portions 45. The spring accommodating portion 45 is composed of a cylindrical portion 46 whose rear end is partially blocked by a rear wall 47 with its axis line oriented in the front-rear direction, and an arc-shaped portion 48 that is flush with the front end of the cylindrical portion 46. Is done. When the cylindrical portion 46 is virtually divided into four upper, lower, left and right quadrant arc regions, the arc-shaped portion 48 is formed on the outer side in the width direction of the upper quadrant arc region and the two side portions. This is a range corresponding to the quarter arc region of the side portion located at.
 図9,17に示すように、円筒部46と円弧状部48で包囲された前後方向に細長い空間は、バネ収容空間49となっている。バネ収容空間49内には、圧縮コイルバネからなるバネ部材56が同軸状に収容されている。円弧状部48の前端縁には、内側へ突出する前面壁50が形成されている。前面壁50の前面は、前枠42の前端縁よりも少し後方に位置する。前面壁50は、バネ収容空間49の前端の開口領域を部分的に覆い隠す。バネ部材56は、後面壁47と前面壁50との間で挟まれることにより、バネ収容空間49からの離脱を規制されている。バネ部材56の前端部のうち、前面壁50と非対応の領域は、前方(正面側)へ露出している。 As shown in FIGS. 9 and 17, a space elongated in the front-rear direction surrounded by the cylindrical portion 46 and the arc-shaped portion 48 is a spring accommodating space 49. In the spring accommodating space 49, a spring member 56 made of a compression coil spring is accommodated coaxially. A front wall 50 projecting inward is formed at the front edge of the arc-shaped portion 48. The front surface of the front wall 50 is located slightly behind the front edge of the front frame 42. The front wall 50 partially covers the opening area at the front end of the spring accommodating space 49. The spring member 56 is sandwiched between the rear wall 47 and the front wall 50, so that separation from the spring accommodating space 49 is restricted. Of the front end portion of the spring member 56, a region not corresponding to the front wall 50 is exposed to the front (front side).
 図9に示すように、側枠43は、バネ収容部45に一体形成された立壁部51を有する。立壁部51は、バネ収容部45の上面における内側の側縁部から上方へ立ち上がった形態であり、前後方向に直線状に延びている。立壁部51の上端縁は、前枠42の左右両端に対して略直角に連なっている。側枠43は、立壁部51に一体形成された庇部52を有する。庇部52は、立壁部51の上端縁から幅方向における外側へ張り出し、バネ収容部45に接近するように斜め下方へ片持ち状に延出した形態である。庇部52も、立壁部51と同様、前後方向に延びている。立壁部51の上端縁と庇部52の上端面は、前枠42の上面と同じく、検知部材40の外面40Sを構成する。 As shown in FIG. 9, the side frame 43 has a standing wall portion 51 integrally formed with the spring accommodating portion 45. The standing wall portion 51 has a form that rises upward from the inner side edge portion on the upper surface of the spring accommodating portion 45, and extends linearly in the front-rear direction. The upper end edge of the upright wall portion 51 is connected substantially at right angles to the left and right ends of the front frame 42. The side frame 43 has a flange portion 52 that is integrally formed with the standing wall portion 51. The flange portion 52 has a shape that protrudes outward in the width direction from the upper end edge of the standing wall portion 51 and extends obliquely downward so as to approach the spring accommodating portion 45. Similarly to the standing wall portion 51, the flange portion 52 extends in the front-rear direction. The upper end edge of the upright wall portion 51 and the upper end surface of the flange portion 52 constitute the outer surface 40S of the detection member 40, similarly to the upper surface of the front frame 42.
 側枠43は、左右一対の溝部53を有する。溝部53は、バネ収容部45の上面と、立壁部51と、庇部52で囲まれた形態であり、前端が開放されている。また、溝部53は、その全長に亘り、幅方向における外方にも開放されている。溝部53は、リブ23と協動することにより、周壁部17が開口部22の開口幅を変化させるように変形するのを規制する機能と、検知部材40をロック解除位置と検知位置との間で移動する際のガイドとしての機能とを発揮する。 The side frame 43 has a pair of left and right groove portions 53. The groove portion 53 is surrounded by the upper surface of the spring accommodating portion 45, the standing wall portion 51, and the flange portion 52, and the front end is open. Moreover, the groove part 53 is open | released also in the outward in the width direction over the full length. The groove portion 53 cooperates with the rib 23 to restrict the deformation of the peripheral wall portion 17 so as to change the opening width of the opening portion 22, and the detection member 40 between the unlock position and the detection position. It will function as a guide when moving in.
 図10に示すように、連結部54は、側枠43の後端における下端部同士(円筒部46同士)を連結している。連結部54は、ロック解除部57よりも下方に位置する。したがって、検知部材40の後端面には、左右両側枠43とロック解除部57と連結部54とで囲まれた開放部59が開口している。連結部54の後端面は、側枠43の後面及びロック解除部57の後面と面一状に繋がっていて、検知部材40の後端面を構成する。 As shown in FIG. 10, the connecting portion 54 connects the lower ends (cylindrical portions 46) at the rear end of the side frame 43. The connecting portion 54 is located below the lock releasing portion 57. Therefore, an open portion 59 surrounded by the left and right side frames 43, the lock release portion 57, and the connecting portion 54 is opened at the rear end surface of the detection member 40. The rear end surface of the connecting portion 54 is connected to the rear surface of the side frame 43 and the rear surface of the lock releasing portion 57 so as to form the rear end surface of the detection member 40.
 検知部材40は、連結部54と枠部41により、平面形状が略方形をなす枠状に構成されている。連結部54には、前方へ片持ち状に延出した形態の撓み係止片55が形成されている。撓み係止片55は、幅方向における中央部に位置し、上下方向(端子収容部11の上面15に対して接近・離間する方向)へ弾性変位し得るようになっている。 The detecting member 40 is constituted by a connecting part 54 and a frame part 41 in a frame shape in which the planar shape is substantially square. The connecting portion 54 is formed with a bending locking piece 55 in a form that cantilevered forward. The flexure locking piece 55 is positioned at the center in the width direction and can be elastically displaced in the vertical direction (direction approaching / separating from the upper surface 15 of the terminal accommodating portion 11).
 上記構成になる検知部材40は、第1ハウジング10に対しロック解除位置と検知位置との間での移動可能に組み付けられている。ロック解除位置は、検知部材40の変位範囲における前端に設定され、検知位置は、検知部材40の変位範囲における後端に設定されている。初期位置は、ロック解除位置よりも少し後方の位置、つまり、検知部材40の移動経路の途中の位置に設定されている。図1,4に示すように、検知部材40は、第1ハウジング10の後方から溝部53をリブ23に嵌合させるようにして組み付けられる。リブ23と溝部53の嵌合により、検知部材40は、ロック解除位置と検知位置との間で円滑に移動し得るようにガイドされる。 The detection member 40 configured as described above is assembled to the first housing 10 so as to be movable between the unlock position and the detection position. The unlocking position is set at the front end in the displacement range of the detection member 40, and the detection position is set at the rear end in the displacement range of the detection member 40. The initial position is set to a position slightly behind the lock release position, that is, a position in the middle of the movement path of the detection member 40. As shown in FIGS. 1 and 4, the detection member 40 is assembled from the rear of the first housing 10 so that the groove 53 is fitted to the rib 23. By the fitting of the rib 23 and the groove 53, the detection member 40 is guided so as to be able to move smoothly between the unlocking position and the detection position.
 検知部材40が第1ハウジング10に組み付けられた状態では、バネ収容部45の少なくとも前端側領域が嵌合空間21内に位置し、立壁部51が開口部22を貫通し、前枠42の全体と庇部52の全体が周壁部17よりも外周側(嵌合空間21の外部)に位置する。また、図3に示すように、左右両側枠43の内側の縁部は、ロックアーム25(アーム部27)の左右両外側縁よりも少し幅方向外方に位置する。 In a state where the detection member 40 is assembled to the first housing 10, at least the front end side region of the spring accommodating portion 45 is located in the fitting space 21, the standing wall portion 51 penetrates the opening portion 22, and the entire front frame 42. And the whole collar part 52 is located in the outer peripheral side (outside the fitting space 21) rather than the surrounding wall part 17. FIG. Further, as shown in FIG. 3, the inner edges of the left and right side frames 43 are positioned slightly outward in the width direction from the left and right outer edges of the lock arm 25 (arm part 27).
 また、図12,14~16に示すように、ロックアーム25がロック姿勢をとるときに、高さ方向においては、ロックアーム25の全体が、検知部材40の上端(外面40S)から下端に至る高さ範囲内に収まるように位置する。連結部54の前端部と撓み係止片55の全体は、ロックアーム25の下方(ロックアーム25と端子収容部11との間)に位置する。前枠42は、ロックアーム25のアーム部27よりも上方に位置する。検知部材40の後方からは、その後端面の開放部59を通してロックアーム25を目視できるようになっている。 As shown in FIGS. 12 and 14 to 16, when the lock arm 25 takes the locked posture, the entire lock arm 25 extends from the upper end (outer surface 40S) to the lower end of the detection member 40 in the height direction. Located within the height range. The front end portion of the connecting portion 54 and the entire bending locking piece 55 are located below the lock arm 25 (between the lock arm 25 and the terminal accommodating portion 11). The front frame 42 is positioned above the arm portion 27 of the lock arm 25. From the rear side of the detection member 40, the lock arm 25 can be seen through the opening 59 on the rear end face.
 検知部材40が初期位置にある状態では、検知部材40がバネ部材56の付勢により後方(検知位置側)へ付勢されるとともに、図12に示すように、撓み係止片55の前端部が第1ストッパ16に対して前方から係止する。この係止作用とバネ部材56の付勢により、検知部材40は初期位置に保持される。バネ収容部45の前端面45Fは、立壁部51と前枠42の最前端面よりも後方に位置しており、検知部材40が初期位置に保持されている状態では、図12に示すように、バネ収容部45の前端面45Fが周壁部17の覆い部24に対して後方に離間した位置にある。この前端面45Fと覆い部24との間の前後方向の間隔は、検知部材40が初期位置からロック解除位置へ移動することを許容するための移動許容空間70となる。 In a state where the detection member 40 is in the initial position, the detection member 40 is urged rearward (detection position side) by the urging of the spring member 56, and as shown in FIG. Is locked to the first stopper 16 from the front. The detection member 40 is held at the initial position by the locking action and the biasing of the spring member 56. The front end surface 45F of the spring accommodating portion 45 is located behind the front end surfaces of the standing wall portion 51 and the front frame 42, and in a state where the detection member 40 is held at the initial position, as shown in FIG. The front end face 45F of the spring accommodating part 45 is located at a position spaced rearward from the cover part 24 of the peripheral wall part 17. The distance in the front-rear direction between the front end face 45F and the cover portion 24 becomes a movement allowance space 70 for allowing the detection member 40 to move from the initial position to the lock release position.
 また、検知部材40が初期位置にある状態では、図2,12に示すように、前枠42が、ロックアーム25の前端縁よりも前方に位置する。つまり、前枠42の後縁のうち補強部44が形成されていない中央部の後縁が、ロックアーム25の幅狭部30の前端縁よりも少し前方に位置する。したがって、図13に示すように、ロックアーム25は、ロック突起28が形成されている前端側領域を上方へ変位させて枠部41で囲まれた空間内に進出させるロック解除姿勢へ弾性変位することができる。 In the state where the detection member 40 is in the initial position, the front frame 42 is positioned forward of the front end edge of the lock arm 25 as shown in FIGS. That is, the rear edge of the central portion where the reinforcing portion 44 is not formed among the rear edges of the front frame 42 is positioned slightly forward of the front edge of the narrow portion 30 of the lock arm 25. Therefore, as shown in FIG. 13, the lock arm 25 is elastically displaced to the unlocking posture in which the front end side region where the lock protrusion 28 is formed is displaced upward to advance into the space surrounded by the frame portion 41. be able to.
 同じく、検知部材40が初期位置にあり、ロックアーム25がロック姿勢をとる状態では、ロック解除部57がロックアーム25の受圧面33に対して斜め上後方から接近して対向するように位置する。つまり、ロック解除部57から受圧面33に対して押圧力は付与されていない。また、ロックアーム25がロック姿勢からロック解除姿勢へ弾性変位するときには、受圧部31がロック解除部57から離間するように下方へ変位するようになっている。したがって、検知部材40が初期位置にあるときに、ロック解除部57は、ロックアーム25のロック解除姿勢への弾性変位動作を妨げることがない。 Similarly, when the detection member 40 is in the initial position and the lock arm 25 is in the locked position, the lock release portion 57 is positioned so as to approach and face the pressure receiving surface 33 of the lock arm 25 obliquely from above and behind. . That is, no pressing force is applied to the pressure receiving surface 33 from the lock release portion 57. When the lock arm 25 is elastically displaced from the lock posture to the lock release posture, the pressure receiving portion 31 is displaced downward so as to be separated from the lock release portion 57. Therefore, when the detection member 40 is in the initial position, the lock release unit 57 does not hinder the elastic displacement operation of the lock arm 25 to the lock release posture.
 検知部材40が検知位置にある状態では、図16に示すように、撓み係止片55が第1ストッパ16から外れ、バネ部材56の付勢により、前枠42が第2ストッパ32に対して前方(初期位置側)から当接する。この当接作用とバネ部材56の付勢により、検知部材40は、検知位置よりも後方への変位を規制され、検知位置に保持される。また、検知部材40が検知位置にある状態では、図3,16に示すように、前枠42が、ロックアーム25の前端縁の上方に重なるように位置する。したがって、ロックアーム25がロック解除姿勢へ弾性変位しようとしても、前枠42に当接するので、ロックアーム25は、ロック解除姿勢への弾性変位を規制され、ロック姿勢に保持される。また、ロック解除部57は、ロックアーム25に対して後方へ遠ざかった位置にある。 In the state in which the detection member 40 is in the detection position, as shown in FIG. 16, the bending locking piece 55 is detached from the first stopper 16, and the front frame 42 is moved with respect to the second stopper 32 by the bias of the spring member 56. Contact from the front (initial position side). Due to this abutting action and biasing of the spring member 56, the detection member 40 is restricted from being displaced rearward from the detection position and is held at the detection position. When the detection member 40 is in the detection position, the front frame 42 is positioned so as to overlap above the front end edge of the lock arm 25 as shown in FIGS. Therefore, even if the lock arm 25 is about to be elastically displaced to the unlocking posture, the lock arm 25 is in contact with the front frame 42, so that the elastic displacement to the unlocking posture is restricted and the lock arm 25 is held in the locked posture. Further, the lock release portion 57 is located away from the lock arm 25 in the rearward direction.
 <第2ハウジング60>
 図2,12に示すように、第2ハウジング60は、端子保持部61と、端子保持部61から正面側に向かって角筒状に延出するフード部62とを一体に形成して構成されている。フード部62を構成する上面壁63には、その外面(上面)から突出するロック用受け部64が形成されている。フード部62の上面壁63には、ロック用受け部64を幅方向に挟むように配された一対の押圧部65が突出形成されている。両ハウジング10,60を嵌合する際には、フード部62が嵌合空間21内に嵌入されるようになっている。
<Second housing 60>
As shown in FIGS. 2 and 12, the second housing 60 is configured by integrally forming a terminal holding portion 61 and a hood portion 62 extending in a rectangular tube shape from the terminal holding portion 61 toward the front side. ing. A lock receiving portion 64 protruding from the outer surface (upper surface) is formed on the upper surface wall 63 constituting the hood portion 62. On the upper surface wall 63 of the hood portion 62, a pair of pressing portions 65 arranged so as to sandwich the lock receiving portion 64 in the width direction are formed to protrude. When the two housings 10 and 60 are fitted together, the hood portion 62 is fitted into the fitting space 21.
 <実施例1の作用及び効果>
 両ハウジング10,60を嵌合する際には、予め、図12に示すように検知部材40を初期位置に保持しておく。そして、フード部62を嵌合空間21に進入させることにより、両ハウジング10,60の嵌合が開始される。嵌合が進む過程では、図13に示すように、ロックアーム25の前端部(幅狭部30)にロック用受け部64が突き当たる。このロック用受け部64の押圧作用により、ロックアーム25のうち脚部26よりも前方の領域が、上方(ロック解除方向)へ弾性変位させられて枠部41で囲まれた空間内に進出し、ロック突起28がロック用受け部64に乗り上がる。つまり、ロックアーム25がロック姿勢からロック解除姿勢へ弾性変位する。
<Operation and Effect of Example 1>
When the two housings 10 and 60 are fitted, the detection member 40 is held in the initial position in advance as shown in FIG. And the fitting of both the housings 10 and 60 is started by making the food | hood part 62 approach into the fitting space 21. FIG. In the process of fitting, the lock receiving portion 64 abuts against the front end portion (the narrow portion 30) of the lock arm 25 as shown in FIG. Due to the pressing action of the lock receiving portion 64, the region of the lock arm 25 in front of the leg portion 26 is elastically displaced upward (in the unlocking direction) and advances into the space surrounded by the frame portion 41. The lock projection 28 rides on the lock receiving portion 64. That is, the lock arm 25 is elastically displaced from the locked posture to the unlocked posture.
 両ハウジング10,60の嵌合が開始してから図13の状態まで嵌合が進む間、図18に示すように、バネ部材56が、フード部62の押圧部65で前方から押されて後面壁47との間で弾縮変形させられる。このバネ部材56の弾性変形により、検知部材40には、初期位置から検知位置に向かう方向への付勢力が付与される。しかし、図13に示すように、撓み係止片55は第1ストッパ16に係止した状態に保たれているので、検知部材40は、検知位置側へ付勢されたまま、初期位置に留まっている。 While the fitting of both the housings 10 and 60 starts and the fitting proceeds to the state shown in FIG. 13, the spring member 56 is pushed from the front by the pressing portion 65 of the hood portion 62 as shown in FIG. It is elastically deformed between the face wall 47. Due to the elastic deformation of the spring member 56, a biasing force in the direction from the initial position toward the detection position is applied to the detection member 40. However, as shown in FIG. 13, since the bending locking piece 55 is held in a state of being locked to the first stopper 16, the detection member 40 remains in the initial position while being biased toward the detection position side. ing.
 図13の状態から嵌合が少し進むと、図14に示すように、ロック突起28がロック用受け部64を通過するので、ロックアーム25はロック解除姿勢からロック姿勢に弾性復帰し、ロック突起28がロック用受け部64に係止する。この係止作用により、両ハウジング10,60が離脱規制状態にロックされるが、係止した時点では、第1ハウジング10の前端面と第2ハウジング60の端子保持部61の前端面(フード部62の奥端面)との間に、更なる嵌合動作の継続を可能にするクリアランスが確保されている。また、図14の状態では、フード部62の上面壁63の先端縁が撓み係止片55の前端に当接することにより、撓み係止片55が少し上方へ弾性変位し、撓み係止片55と第1ストッパ16との係止代が減少する。 When the fitting is slightly advanced from the state of FIG. 13, as shown in FIG. 14, the lock protrusion 28 passes through the lock receiving portion 64, so that the lock arm 25 is elastically returned from the unlocked position to the locked position, and the lock protrusion 28 is engaged with the lock receiving portion 64. Due to this locking action, both housings 10 and 60 are locked in the disengagement restricted state, but at the time of locking, the front end surface of the first housing 10 and the front end surface of the terminal holding portion 61 of the second housing 60 (the hood portion). The clearance which enables the further fitting operation to continue is ensured between the rear end face 62 and the rear end face 62. Further, in the state of FIG. 14, the leading edge of the upper surface wall 63 of the hood portion 62 abuts against the front end of the bending locking piece 55, whereby the bending locking piece 55 is elastically displaced slightly upward, and the bending locking piece 55. The locking margin between the first stopper 16 and the first stopper 16 is reduced.
 そして、図14の状態から嵌合が進むと、図15に示すように、両ハウジング10,60が突き当たって嵌合動作が停止する。この間、撓み係止片55が、フード部62の上面壁63によって更に上方へ変位させられるので、撓み係止片55が第1ストッパ16から完全に外れる。すると、検知部材40が、バネ部材56の付勢によって初期位置から検知位置へ一気に移動し、図16及び図19に示すように、前枠42が第2ストッパ32に当接して、検知部材40が検知位置で停止する。検知部材40が検知位置へ変位したことは、目視及び、前枠42と第2ストッパ32との衝突音とによって知ることができる。 Then, when the fitting proceeds from the state of FIG. 14, as shown in FIG. 15, both housings 10 and 60 come into contact with each other, and the fitting operation is stopped. During this time, since the bending locking piece 55 is displaced further upward by the upper surface wall 63 of the hood portion 62, the bending locking piece 55 is completely detached from the first stopper 16. Then, the detection member 40 is moved from the initial position to the detection position at a stroke by the urging of the spring member 56, and the front frame 42 comes into contact with the second stopper 32 as shown in FIGS. Stops at the detection position. The fact that the detection member 40 has been displaced to the detection position can be recognized by visual observation and the collision sound between the front frame 42 and the second stopper 32.
 検知部材40が検知位置に変位すると、両ハウジング10,60の嵌合が完了する。もし、両ハウジング10,60の嵌合が不完全な状態で嵌合作業を中断した場合は、検知部材40が検知位置へ移動せず、初期位置に留まったままである。したがって、検知部材40が初期位置から検知位置へ移動したか否かに基づいて、作業者は、両ハウジング10,60が正規嵌合されたか否かを検知することができる。 When the detection member 40 is displaced to the detection position, the fitting of the two housings 10 and 60 is completed. If the fitting operation is interrupted in a state in which the housings 10 and 60 are not completely fitted, the detection member 40 does not move to the detection position and remains at the initial position. Therefore, based on whether or not the detection member 40 has moved from the initial position to the detection position, the operator can detect whether or not the two housings 10 and 60 are properly fitted.
 本実施例1では、両ハウジング10,60の嵌合を開始してから嵌合完了に至る過程で、まず、両ハウジング10,60がロックアーム25とロック用受け部64との係止によるロック作用によって正規嵌合状態にロックされ、その後で、検知部材40の検知位置への移動が許容される。したがって、嵌合作業を半嵌合状態で中断した場合には、検知部材40が初期位置に保持されるので、検知部材40を検知位置から初期位置に戻す作業を行わなくても、嵌合作業を再開することができる。 In the first embodiment, in the process from the start of fitting of the two housings 10, 60 to the completion of fitting, first, the two housings 10, 60 are locked by locking the lock arm 25 and the lock receiving portion 64. It is locked in the normal fitting state by the action, and thereafter the detection member 40 is allowed to move to the detection position. Therefore, when the fitting operation is interrupted in the half-fitted state, the detection member 40 is held at the initial position, so that the fitting operation can be performed without performing the operation of returning the detection member 40 from the detection position to the initial position. Can be resumed.
 両ハウジング10,60が正規嵌合してロックアーム25により離脱規制されている状態では、ロックアーム25の前端部は、検知部材40の前枠42によりロック解除方向(ロック用受け部64から解離する方向)への弾性変位が規制されている。これにより、受圧部31を下方へ押し操作したり、受圧部31に対して他部材が干渉して下向きの押圧力を付与しても、ロック突起28がロック用受け部64に係止した状態が維持され、ロックアーム25はロック姿勢に保持される。したがって、ロックアーム25によるロックが解除されることはない。 In a state where both the housings 10 and 60 are properly fitted and detachment restricted by the lock arm 25, the front end portion of the lock arm 25 is disengaged from the lock receiving portion 64 by the front frame 42 of the detection member 40. The elastic displacement in the direction of movement) is restricted. Thus, even when the pressure receiving portion 31 is pushed downward or another member interferes with the pressure receiving portion 31 to apply a downward pressing force, the lock projection 28 is locked to the lock receiving portion 64. Is maintained, and the lock arm 25 is held in the locked posture. Therefore, the lock by the lock arm 25 is not released.
 嵌合状態にロックされている両ハウジング10,60を離脱させる際には、検知位置にある検知部材40を、バネ部材56の付勢に抗しながら前方(ロック解除位置側)へ移動させる。検知部材40が初期位置に到達すると、図15に示すように、ロックアーム25の前端部が前枠42による変位規制から解放されるので、ロックアーム25はロック解除方向への弾性変位が可能な状態となる。検知部材40が初期位置に到達したとき、検知部材40は、移動許容空間70によって、更に前方(ロック解除位置側)へ移動することが可能となっている。したがって、検知部材40が初期位置に到達した後も、引き続き、検知部材40を前方へ移動させる。 When removing both housings 10 and 60 locked in the fitted state, the detection member 40 at the detection position is moved forward (to the unlock position side) against the bias of the spring member 56. When the detection member 40 reaches the initial position, as shown in FIG. 15, the front end of the lock arm 25 is released from the displacement restriction by the front frame 42, so that the lock arm 25 can be elastically displaced in the unlocking direction. It becomes a state. When the detection member 40 reaches the initial position, the detection member 40 can be moved further forward (on the lock release position side) by the movement allowable space 70. Accordingly, even after the detection member 40 reaches the initial position, the detection member 40 is continuously moved forward.
 検知部材40が初期位置よりも前方へ移動し始めると、検知部材40に形成されているロック解除部57の押圧縁部58が、ロックアーム25に形成されている受圧面33に当接して受圧面33を前方へ押圧する。受圧面33は、ロックアーム25の弾性変位方向と検知部材40の移動方向の両方向に対して傾斜しているので、ロック用押圧縁部58から受圧面33に付与された押圧力により、ロック姿勢のロックアーム25はロック解除方向へ弾性変位させられる。そして、検知部材40がロック解除位置に到達すると、図20に示すように、ロック解除部57が受圧部31の上に乗り上がり、ロックアーム25は、ロック解除姿勢となってロック用受け部64に対して上方へ解離する。これにより、ロックアーム25とロック用受け部64との係止によるロック状態が解除される。この後は、ロックアーム25のロック解除状態を維持したままで、両ハウジング10,60を引き離せばよい。 When the detection member 40 starts to move forward from the initial position, the pressing edge portion 58 of the unlocking portion 57 formed on the detection member 40 comes into contact with the pressure receiving surface 33 formed on the lock arm 25 and receives pressure. The surface 33 is pressed forward. Since the pressure receiving surface 33 is inclined with respect to both the elastic displacement direction of the lock arm 25 and the moving direction of the detection member 40, the pressure receiving surface 33 is locked by the pressing force applied to the pressure receiving surface 33 from the locking pressing edge 58. The lock arm 25 is elastically displaced in the unlocking direction. When the detection member 40 reaches the unlocking position, as shown in FIG. 20, the unlocking portion 57 rides on the pressure receiving portion 31, and the lock arm 25 enters the unlocking posture and receives the locking receiving portion 64. Dissociate upward. Thereby, the locked state by the locking of the lock arm 25 and the lock receiving portion 64 is released. Thereafter, both the housings 10 and 60 may be pulled apart while maintaining the unlocked state of the lock arm 25.
 本実施例1のコネクタは、第1ハウジング10と、ロック用受け部64が形成された第2ハウジング60と、第1ハウジング10に形成され、ロック用受け部64と係止することで両ハウジング10,60を正規嵌合状態にロックするロックアーム25とを備える。そして、第1ハウジング10には、初期位置を通過する経路に沿って検知位置とロック解除位置との間で移動し得るように検知部材40が取り付けられている。検知部材40は、両ハウジング10,60の嵌合過程では検知位置への移動を規制された状態で初期位置に保持され、両ハウジング10,60が正規嵌合した状態では検知位置とロック解除位置との間の移動を許容されるようになっている。 The connector according to the first embodiment includes a first housing 10, a second housing 60 in which a lock receiving portion 64 is formed, and a housing formed on the first housing 10 and being engaged with the lock receiving portion 64. And a lock arm 25 that locks 10 and 60 in a normal fitting state. And the detection member 40 is attached to the 1st housing 10 so that it can move between a detection position and a lock release position along the path | route which passes an initial position. The detection member 40 is held at the initial position in a state where the movement to the detection position is restricted during the fitting process of both the housings 10 and 60, and the detection position and the unlocking position when both the housings 10 and 60 are properly fitted. The movement between is allowed.
 さらに、コネクタは、両ハウジング10,60の嵌合過程で、第2ハウジング60で押されることにより検知部材40を検知位置側へ付勢し、両ハウジング10,60が正規嵌合したときには検知部材40を初期位置から検知位置へ移動させることで嵌合状態の検知動作を行わせるバネ部材56を備える。そして、検知部材40には、両ハウジング10,60が正規嵌合した状態において、検知部材40が初期位置からロック解除位置へ移動する過程でロックアーム25をロック解除方向へ弾性撓みさせるロック解除部57とを備えている。 Further, the connector urges the detection member 40 to the detection position side by being pushed by the second housing 60 in the process of fitting the two housings 10 and 60, and when the both housings 10 and 60 are properly fitted, the detection member. A spring member 56 is provided that moves the connector 40 from the initial position to the detection position to perform a fitting state detection operation. And the lock release part which elastically bends the lock arm 25 to a lock release direction in the process in which the detection member 40 moves to the lock release position from the initial position in the state which both housings 10 and 60 fitted normally to the detection member 40. 57.
 この構成によれば、正規嵌合状態の両ハウジング10,60を離脱する際には、検知位置にある検知部材40を、バネ部材56の付勢に抗して押し動かし、初期位置を通過させてロック解除位置まで移動させる。検知部材40が初期位置からロック解除位置へ移動する過程では、ロック解除部57がロックアーム25をロック解除方向へ弾性撓みさせるので、検知部材40をロック解除位置へ移動させた状態のまま、両ハウジング10,60を引き離せばよい。 According to this configuration, when the two housings 10 and 60 in the normal fitting state are detached, the detection member 40 at the detection position is pushed against the bias of the spring member 56 to pass the initial position. To the unlock position. In the process in which the detection member 40 moves from the initial position to the lock release position, the lock release portion 57 elastically bends the lock arm 25 in the lock release direction, so that both the detection member 40 is moved to the lock release position. The housings 10 and 60 may be pulled apart.
 このように本実施例1では、ロックアーム25によるロックを解除する際には、検知部材40を検知位置からロック解除位置まで押し動かすというワンアクションの操作だけで済む。したがって、検知部材を検知位置から初期位置へ移動させる作業と、その後に、検知部材から手を離してロックアームをロック解除操作する作業をツーアクションで別々に行う場合に比べると、本実施例1のコネクタは作業性に優れている。 As described above, in the first embodiment, when the lock by the lock arm 25 is released, only one action of pushing the detection member 40 from the detection position to the lock release position is required. Therefore, compared with the case where the operation of moving the detection member from the detection position to the initial position and the operation of releasing the lock arm by releasing the hand from the detection member are performed separately in two actions, the first embodiment. The connector is excellent in workability.
 また、本実施例1のコネクタでは、ロックアーム25に、ロックアーム25の弾性撓み方向及び検知部材40の移動方向の両方向に対して傾斜した受圧面33を形成している。この構成によれば、ロック解除部57がロックアーム25を弾性撓みさせる際には、受圧面33の傾斜によってロック解除部57とロックアーム25との間の摺動抵抗が低減されるので、作業性に優れている。 In the connector of the first embodiment, the lock arm 25 is formed with a pressure receiving surface 33 that is inclined with respect to both the elastic deflection direction of the lock arm 25 and the moving direction of the detection member 40. According to this configuration, when the lock release portion 57 elastically deflects the lock arm 25, the sliding resistance between the lock release portion 57 and the lock arm 25 is reduced by the inclination of the pressure receiving surface 33. Excellent in properties.
 また、本実施例1のコネクタは、端子収容部11を周壁部17で包囲した形態の第1ハウジング10と、第1ハウジング10と嵌合可能な第2ハウジング60と、端子収容部11と周壁部17との間の嵌合空間21内において初期位置から検知位置へ移動するか否かに基づいて両ハウジング10,60の嵌合状態を検知する検知部材40を備えている。さらに、周壁部17の周方向における一部を切欠した形態であって検知部材40を外周側へ露出させる開口部22と、周壁部17と検知部材40とに形成され、互いに嵌合することで、検知部材40の初期位置と検知位置との間での移動を許容し、且つ周壁部17が開口部22の開口幅を変化させるように変形するのを規制する変形規制部(リブ23と溝部53)とを備えている。 Further, the connector according to the first embodiment includes a first housing 10 in a form in which the terminal housing portion 11 is surrounded by the peripheral wall portion 17, a second housing 60 that can be fitted to the first housing 10, the terminal housing portion 11 and the peripheral wall. A detecting member 40 that detects the fitting state of both the housings 10 and 60 based on whether or not to move from the initial position to the detecting position in the fitting space 21 between the housing 17 and the portion 17 is provided. Furthermore, it is the form which notched the part in the circumferential direction of the surrounding wall part 17, Comprising: It forms in the opening part 22 which exposes the detection member 40 to an outer peripheral side, the surrounding wall part 17, and the detection member 40, and it mutually fits. Deformation restricting portions (ribs 23 and groove portions) that allow the detecting member 40 to move between the initial position and the detecting position and restrict the deformation of the peripheral wall portion 17 so as to change the opening width of the opening portion 22. 53).
 この構成によれば、周壁部17の開口部22は検知部材40を外周側へ露出させるように開口しているので、検知部材40の外周側には周壁部17は存在しない。したがって、検知部材の外周側に周壁部が存在する場合に比べると、本実施例1のコネクタは、第1ハウジング10を小型化することができる。また、周壁部17に開口部22が形成されていると、周壁部17が開口部22の開口幅を変化させるように変形することが懸念されるが、本実施例1では、周壁部17における開口部22の開口縁のリブ23と、検知部材40に形成した溝部53とを嵌合させることにより、周壁部17の変形を防止している。 According to this configuration, since the opening 22 of the peripheral wall portion 17 is opened so as to expose the detection member 40 to the outer peripheral side, the peripheral wall portion 17 does not exist on the outer peripheral side of the detection member 40. Therefore, the connector of the first embodiment can reduce the size of the first housing 10 as compared with the case where the peripheral wall portion exists on the outer peripheral side of the detection member. Further, when the opening 22 is formed in the peripheral wall portion 17, there is a concern that the peripheral wall portion 17 is deformed so as to change the opening width of the opening portion 22, but in the first embodiment, in the peripheral wall portion 17. The peripheral wall 17 is prevented from being deformed by fitting the rib 23 at the opening edge of the opening 22 with the groove 53 formed in the detection member 40.
 また、周壁部17の変形規制部であるリブ23は、開口部22の開口縁部から外周側へ突出した形態であり、検知部材40側の変形規制部である溝部53は、リブ23を略周方向に挟むとともに、開口部22の開口縁部とリブ23とを略径方向に挟む形態である。この構成によれば、開口部22が周方向に拡がったり狭まったりすることを規制できるのに加え、検知部材40が周壁部17に対して径方向へ相対変位することも規制できる。 Further, the rib 23 that is a deformation restricting portion of the peripheral wall portion 17 has a form protruding from the opening edge portion of the opening portion 22 to the outer peripheral side, and the groove portion 53 that is a deformation restricting portion on the detection member 40 side is substantially the rib 23. While sandwiching in the circumferential direction, the opening edge portion of the opening 22 and the rib 23 are sandwiched in the substantially radial direction. According to this configuration, in addition to restricting the opening 22 from expanding or narrowing in the circumferential direction, the relative displacement of the detection member 40 relative to the peripheral wall 17 in the radial direction can also be restricted.
 また、端子収容部11と周壁部17との間の嵌合空間21内には、両ハウジング10,60を嵌合状態にロックするためのロックアーム25が配され、端子収容部11とロックアーム25が並ぶ上下方向(高さ方向)に関して、検知部材40とロックアーム25が少なくとも部分的に重なる形態である。このように、端子収容部11とロックアーム25が並ぶ方向に関して、検知部材40とロックアーム25が少なくとも部分的に重なることにより、第1ハウジング10を小型化することができる。 A lock arm 25 for locking both housings 10 and 60 in a fitted state is disposed in the fitting space 21 between the terminal containing portion 11 and the peripheral wall portion 17. The detection member 40 and the lock arm 25 overlap at least partially with respect to the vertical direction (height direction) in which 25 is arranged. Thus, the first housing 10 can be reduced in size by at least partially overlapping the detection member 40 and the lock arm 25 in the direction in which the terminal accommodating portion 11 and the lock arm 25 are arranged.
 また、ロックアーム25と検知部材40は、第1ハウジング10の上面15に沿うように配されており、検知部材40は、検知部材40の外面40Sを構成して、ロックアーム25を囲むとともにロックアーム25の外面31Sを露出させる形態の枠部41を備えている。そして、枠部41は、第1ハウジング10の上面15とロックアーム25とが対向する上下方向(高さ方向)において、ロックアーム25の外面31Sよりも内側に配されている。この構成によれば、第1ハウジング10の上面15とロックアーム25とが対向する方向において、小型化を図ることができる。 Further, the lock arm 25 and the detection member 40 are arranged along the upper surface 15 of the first housing 10, and the detection member 40 constitutes an outer surface 40S of the detection member 40 to surround and lock the lock arm 25. The frame part 41 of the form which exposes the outer surface 31S of the arm 25 is provided. The frame portion 41 is disposed on the inner side of the outer surface 31S of the lock arm 25 in the vertical direction (height direction) in which the upper surface 15 of the first housing 10 and the lock arm 25 face each other. According to this configuration, the size can be reduced in the direction in which the upper surface 15 of the first housing 10 and the lock arm 25 face each other.
 また、本実施例1のコネクタは、両ハウジング10,60の嵌合過程で、第2ハウジング60の押圧部65で押されることにより検知部材40を検知位置側へ付勢するバネ部材56と、両ハウジング10,60の嵌合過程では検知部材40をバネ部材56の付勢に抗して初期位置に保持し、両ハウジング10,60が嵌合すると検知部材40の保持を解除する第1ストッパ16と、枠部41を構成し、検知部材40の移動方向と交差する幅方向に延びた形態の前枠42と、第1ストッパ16の保持から解放された検知部材40がバネ部材56の付勢によって検知位置に到達したときに、前枠42を当接させることで検知部材40を検知位置に停止させる第2ストッパ32とを備える。この前枠42には、第1ハウジング10の上面15とロックアーム25とが対向する上下方向と交差する前後方向に肉盛りした形態の補強部44が形成されているので、前枠42の全体としての強度が高まる。したがって、第1ハウジング10の上面15とロックアーム25とが対向する方向において、前枠42の厚さを薄くし、更なる小型化を図ることが可能である。 The connector of the first embodiment includes a spring member 56 that urges the detection member 40 toward the detection position by being pressed by the pressing portion 65 of the second housing 60 during the fitting process of the housings 10 and 60. In the process of fitting the two housings 10 and 60, the detection member 40 is held at the initial position against the bias of the spring member 56, and when the two housings 10 and 60 are fitted, the first stopper is released. 16 and the frame 41 and the front frame 42 extending in the width direction intersecting the moving direction of the detection member 40, and the detection member 40 released from the holding of the first stopper 16 are attached to the spring member 56. The second stopper 32 stops the detection member 40 at the detection position by bringing the front frame 42 into contact when the detection position is reached by the force. The front frame 42 is formed with a reinforcing portion 44 that is built up in the front-rear direction intersecting the vertical direction in which the upper surface 15 of the first housing 10 and the lock arm 25 face each other. As strength increases. Therefore, in the direction in which the upper surface 15 of the first housing 10 and the lock arm 25 face each other, it is possible to reduce the thickness of the front frame 42 and further reduce the size.
 また、両ハウジング10,60の嵌合前は、検知部材40が嵌合空間21内における正面側開口領域に近い初期位置に配され、両ハウジング10,60が正規嵌合すると、検知部材40は嵌合空間21内における奥方の検知位置へ変位するようになっている。そして、嵌合空間21の正面側の開口縁から延出した覆い部24が、検知部材40を正面側から覆うように配されている。この構成によれば、両ハウジング10,60の嵌合過程で、フード部62が嵌合空間21内の検知部材40に向かって進んでも、フード部62は、検知部材40に到達する前に覆い部24に当接するので、両ハウジング10,60が未嵌合や半嵌合であるうちに、検知部材40がフード部62によって検知位置へ押し込まれることはない。したがって、検知部材40がフード部62で押されることに起因して検知動作不良を起こすことを、防止できる。 Further, before the housings 10 and 60 are fitted together, the detection member 40 is arranged at an initial position near the front opening region in the fitting space 21, and when both the housings 10 and 60 are properly fitted, the detection member 40 is It is displaced to the detection position at the back in the fitting space 21. And the cover part 24 extended from the opening edge of the front side of the fitting space 21 is distribute | arranged so that the detection member 40 may be covered from the front side. According to this configuration, even if the hood portion 62 advances toward the detection member 40 in the fitting space 21 during the fitting process of both the housings 10 and 60, the hood portion 62 covers before reaching the detection member 40. Since it contacts the portion 24, the detection member 40 is not pushed into the detection position by the hood portion 62 while both the housings 10, 60 are unfitted or half-fitted. Therefore, it is possible to prevent the detection operation failure from occurring due to the detection member 40 being pushed by the hood portion 62.
 また、覆い部24は、周壁部17に一体に形成されていので、覆い部を周壁部とは別体の部品とした場合に比べると、部品点数を削減できる。さらに、覆い部24は、検知部材40が検知位置からロック解除位置へ変位したときに、検知部材40をロック解除位置で前止まりする形態である。つまり、覆い部24は、検知部材40に対するフード部62の当接を防止する機能と、検知部材40をロック解除位置で前止まりする機能とを兼ね備えている。したがって、検知部材40を前止まりする手段を覆い部24とは別に形成する場合に比べると、第1ハウジング10と検知部材40の形状を簡素することができる。 Moreover, since the cover part 24 is formed integrally with the peripheral wall part 17, the number of parts can be reduced as compared with the case where the cover part is a separate part from the peripheral wall part. Furthermore, the cover part 24 is a form which stops the detection member 40 at the unlock position when the detection member 40 is displaced from the detection position to the unlock position. That is, the cover part 24 has a function of preventing the hood part 62 from coming into contact with the detection member 40 and a function of stopping the detection member 40 in the unlocked position. Therefore, the shapes of the first housing 10 and the detection member 40 can be simplified as compared with the case where the means for stopping the detection member 40 is formed separately from the cover 24.
