Description

本発明は、コネクタに関する。 The present invention relates to connectors.

従来、コネクタにおいては、相手方コネクタとの嵌合状態が完全なるものであるのか否かを作業者等に判断させるための技術が知られている。例えば、コネクタは、仮係止位置と本係止位置との間でのハウジングに対する相対移動が可能な検知部材を備えている（例えば、特許文献１参照）。その検知部材は、コネクタと相手方コネクタとの間（コネクタ間）の嵌合状態が完全なるものでなければ（所謂嵌合解除状態であれば）、仮係止位置から本係止位置まで移動させることができず、その嵌合状態が完全なるものであれば（所謂完全嵌合状態であれば）、仮係止位置から本係止位置まで移動させることができる。作業者等は、そのようなハウジングに対する検知部材の相対的な位置関係に基づいて、コネクタ間の嵌合状態が完全なるものであるのか否かを判断することができる。 2. Description of the Related Art Conventionally, in a connector, there has been known a technique for allowing an operator or the like to judge whether or not the mated state of the connector with the mating connector is perfect. For example, the connector includes a detection member that can move relative to the housing between a temporary locking position and a full locking position (see Patent Document 1, for example). The detection member is moved from the temporary locking position to the full locking position if the mating state between the connector and the mating connector (between the connectors) is not perfect (so-called mating disengaged state). If the mating state is perfect (so-called complete mating state), it can be moved from the temporary locking position to the full locking position. A worker or the like can determine whether or not the mating state between the connectors is perfect based on the relative positional relationship of the detection member with respect to the housing.

次に、検知部材４０の離脱方向側への移動を本係止位置で規制する構成について説明する。検知部材４０は、図１３に示すように、各規制機構側被係止部４８がそれぞれ各規制機構側係止部２６よりも嵌合方向側に位置しており、各規制機構側係止部２６と各規制機構側被係止部４８とが挿抜方向で互いに対向状態にある。ここでは、各規制機構側被係止部４８の離脱方向側への移動をそれぞれ各規制機構側係止部２６で規制する。各規制機構側係止部２６と各規制機構側被係止部４８とによって、本係止位置のときに、ロックアーム３１（ハウジング２０）に対する検知部材４０の離脱方向側への移動を規制する。各規制機構側係止部２６と各規制機構側被係止部４８は、そのときに、挿抜方向で互いに接触させてもよく、挿抜方向で間隔が空いていてもよい。 Next, a configuration for restricting the movement of the detection member 40 in the detachment direction at the final locking position will be described. As shown in FIG. 13 , the detection member 40 has the restriction mechanism side engaged portions 48 positioned closer to the fitting direction than the restriction mechanism side engagement portions 26 . 26 and each regulating mechanism-side engaged portion 48 are opposed to each other in the insertion/removal direction. Here, movement of each restriction mechanism side locked portion 48 in the detachment direction is restricted by each restriction mechanism side locking portion 26 . At the final locking position, each of the regulating mechanism-side engaging portions 26 and each regulating mechanism-side engaged portion 48 regulates the movement of the detection member 40 in the detachment direction from the lock arm 31 (housing 20). . At that time, the restriction mechanism-side engaging portions 26 and the restriction mechanism-side engaged portions 48 may be in contact with each other in the insertion/extraction direction, or may be spaced apart in the insertion/extraction direction.

次に、検知部材４０の嵌合方向側への移動を本係止位置で規制する構成について説明する。検知部材４０においては、図１０、図１１に示すように、検知部材操作部４５がロック用壁部２５ａよりも離脱方向側に位置しており、そのロック用壁部２５ａと検知部材操作部４５とが挿抜方向で互いに対向状態にある。ここでは、それぞれのロック用壁部２５ａで検知部材操作部４５の嵌合方向側への移動を規制する。そのロック用壁部２５ａと検知部材操作部４５とによって、本係止位置のときに、ロックアーム３１（ハウジング２０）に対する検知部材４０の嵌合方向側への移動を規制する。ロック用壁部２５ａと検知部材操作部４５は、そのときに、挿抜方向で互いに接触させている。 Next, a configuration for restricting the movement of the detection member 40 in the fitting direction at the final locking position will be described. In the detection member 40, as shown in FIGS. 10 and 11, the detection member operation portion 45 is located on the detachment side of the lock wall portion 25a, and the lock wall portion 25a and the detection member operation portion 45 are located on the separation direction side. are opposed to each other in the insertion/removal direction. Here, movement of the detection member operation portion 45 in the fitting direction is restricted by the respective locking wall portions 25a. The lock wall portion 25a and the detection member operation portion 45 restrict movement of the detection member 40 in the fitting direction with respect to the lock arm 31 (housing 20) at the final locking position. At this time, the locking wall portion 25a and the detection member operating portion 45 are brought into contact with each other in the insertion/removal direction.

検知部材４０の第一方向側への移動を本係止位置で規制する構造について説明する。検知部材４０においては、図６、図１０、図１１に示すように、各検知部材壁部４３のロック用壁部側端部４３ａがロック用壁部２５ａよりも第二方向側に位置しており、そのロック用壁部２５ａと各ロック用壁部側端部４３ａとが対向方向で互いに対向状態にある。ここでは、それぞれのロック用壁部２５ａで各検知部材壁部４３の第一方向側への移動を規制する。そのロック用壁部２５ａと各ロック用壁部側端部４３ａとによって、本係止位置のときに、ロックアーム３１（ハウジング２０）に対する検知部材４０の第一方向側への移動を規制する。ロック用壁部２５ａと各ロック用壁部側端部４３ａは、そのときに、対向方向で互いに接触させている。 A structure for restricting the movement of the detection member 40 in the first direction at the final locking position will be described. In the detection member 40, as shown in FIGS. 6, 10, and 11, the lock wall side end portion 43a of each detection member wall portion 43 is located on the second direction side of the lock wall portion 25a. The locking wall portion 25a and the locking wall side end portions 43a are opposed to each other in the opposing direction. Here, movement of each detecting member wall portion 43 in the first direction is restricted by each locking wall portion 25a. The locking wall portion 25a and the locking wall side end portions 43a restrict movement of the detection member 40 in the first direction with respect to the lock arm 31 (housing 20) at the final locking position. The locking wall 25a and each locking wall side end 43a are then in contact with each other in opposite directions.

検知部材４０の第二方向側への移動を本係止位置で規制する構造について説明する。検知部材４０においては、図６、図１０、及び図１１に示すように、各検知部材壁部４３が相手方ハウジングＣｈ（相手方フードＣｈｆ）よりも第一方向側に位置しており、その相手方ハウジングＣｈと各検知部材壁部４３とが対向方向で互いに対向状態にある。さらに、各本体部側端部４３ｂが各ガイドレール部２８よりも第一方向側に位置しており、各ガイドレール部２８と各本体部側端部４３ｂとが対向方向で互いに対向状態にある。ここでは、各ガイドレール部２８及び各本体部側突起部４９で各検知部材壁部４３の第二方向側への移動を規制する。各ガイドレール部２８と各本体部側突起部４９とによって、本係止位置のときに、ハウジング２０に対する検知部材４０の第二方向側への移動を規制する。各ガイドレール部２８と各本体部側突起部４９は、そのときに、対向方向で互いに接触させている。 A structure for restricting the movement of the detection member 40 in the second direction at the final locking position will be described. In the detection member 40, as shown in FIGS. 6, 10, and 11, each detection member wall portion 43 is located on the first direction side of the mating housing Ch (the mating hood Chf). Ch and each detection member wall portion 43 are opposed to each other in the opposing direction. Further, each body portion side end portion 43b is located on the first direction side of each guide rail portion 28, and each guide rail portion 28 and each body portion side end portion 43b are in a state of facing each other in the facing direction. . Here, movement of each detecting member wall portion 43 in the second direction is restricted by each guide rail portion 28 and each body portion side projection portion 49 . The guide rail portions 28 and the main body side protrusions 49 restrict movement of the detection member 40 in the second direction with respect to the housing 20 at the final locking position. At that time, each guide rail portion 28 and each main body portion side projection portion 49 are brought into contact with each other in the opposing direction.

また、検知部材４０は、ハウジング２０に対して、本係止位置と固定位置との間で相対移動させることができる。固定位置は、嵌合状態が完全嵌合状態となる前で、検知部材４０がロックアーム３１に取りつけられた状態で、検知部材４０をハウジング２０に保持する位置である。本実施形態における固定位置は、ハウジング２０に対して検知部材４０が組み付けられたときの位置でもある。このため、固定位置においては、コネクタ１と相手方コネクタＣとが互いに挿入される前の状態も含まれている。 Further, the detection member 40 can be moved relative to the housing 20 between the final locking position and the fixed position. The fixed position is a position in which the detection member 40 is held in the housing 20 while the detection member 40 is attached to the lock arm 31 before the mated state becomes the completely mated state. The fixed position in this embodiment is also the position when the detection member 40 is attached to the housing 20 . Therefore, the fixed position also includes the state before the connector 1 and the mating connector C are inserted into each other.

次に、コネクタ１及び相手方コネクタＣの嵌合について説明する。図３及び図４に示すように、検知部材４０が固定位置の状態で、相手方ハウジングＣｈをハウジング２０の環状空間部２３に挿入するようにコネクタ１を嵌合方向に移動させる。コネクタ１が嵌合方向に移動することでハウジング側係止部３１ｂとハウジング側被係止部３２ａとが当接する。ハウジング側係止部３１ｂ及びハウジング側被係止部３２ａは、当接した後、コネクタ１が嵌合方向に移動し続けることで、ハウジング側係止部３１ｂがハウジング側被係止部３２ａによって第一方向へと押動され、ロックアーム３１を撓ませながらハウジング側被係止部３２ａが完全嵌合状態となる位置までハウジング側係止部３１ｂを乗り越える。また、作業者等が、ロックアーム３１におけるハウジング側係止部３１ｂを第一方向へと撓ませた後、コネクタ１が嵌合方向に移動し続けることで、ハウジング側被係止部３２ａを完全嵌合状態となる位置まで移動させてもよい。 Next, fitting of the connector 1 and the mating connector C will be described. As shown in FIGS. 3 and 4, the connector 1 is moved in the mating direction so that the mating housing Ch is inserted into the annular space 23 of the housing 20 while the detection member 40 is in the fixed position. When the connector 1 moves in the mating direction, the housing-side locking portion 31b and the housing-side locked portion 32a come into contact with each other. After the housing-side engaging portion 31b and the housing-side engaged portion 32a abut against each other, the housing-side engaging portion 31b is engaged by the housing-side engaged portion 32a as the connector 1 continues to move in the mating direction. While being pushed in one direction and bending the lock arm 31, the housing-side locked portion 32a climbs over the housing-side locking portion 31b to a position where the housing-side locked portion 32a is in a completely fitted state. Further, after an operator or the like bends the housing-side locking portion 31b of the lock arm 31 in the first direction, the connector 1 continues to move in the fitting direction, thereby completely locking the housing-side locked portion 32a. You may move to the position which will be in a fitting state.

なお、ハウジング側被係止部３２ａがハウジング側係止部３１ｂを第一方向へと押動した後、コネクタ１が嵌合方向に移動し続けることで、検知アーム４２の先端部４２ａがハウジング側被係止部３２ａに接触する。そして、嵌合方向への移動が進むに連れて、ハウジング側被係止部３２ａが先端部４２ａに対して第一方向に向けた力を作用させる。その際、検知部材４０においては、検知アーム４２が離脱方向側の根元を支点にして撓み始める。 After the housing-side locked portion 32a pushes the housing-side locking portion 31b in the first direction, the connector 1 continues to move in the mating direction, so that the tip portion 42a of the detection arm 42 moves toward the housing. It comes into contact with the locked portion 32a. Then, as the movement in the mating direction progresses, the housing-side engaged portion 32a applies a force in the first direction to the distal end portion 42a. At that time, in the detection member 40, the detection arm 42 begins to bend with the base on the detachment direction side as a fulcrum.

完全嵌合状態となる位置では、図１０に示すように、撓ませられていたロックアーム３１が元の位置に戻り、挿抜方向においてハウジング側係止部３１ｂとハウジング側被係止部３２ａとが向かい合うことになる。保持機構３０においては、コネクタ１と相手方コネクタＣとの間の抜去動作が抑制されるので、完全嵌合状態で保持される。また、検知部材４０においては、先端部４２ａがハウジング側係止部３１ｂを乗り越えることができる位置まで、検知アーム４２が撓む。 10, the bent lock arm 31 returns to its original position, and the housing-side locking portion 31b and the housing-side locked portion 32a are aligned in the insertion/removal direction. will face each other. In the holding mechanism 30, the removal operation between the connector 1 and the mating connector C is suppressed, so that they are held in a completely fitted state. Further, in the detection member 40, the detection arm 42 bends to a position where the tip portion 42a can get over the housing-side locking portion 31b.

ロックアーム３１においては、図１０に示すように、完全嵌合状態となる位置まで嵌合方向に移動することによって、ハウジング側係止部３１ｂが解除操作部３２ｂに近づいていく。ハウジング側係止部３１ｂと解除操作部３２ｂとの間においては、完全嵌合状態となる位置での間隔を詰めることによって、ハウジング側係止部３１ｂの嵌合方向側への動きを解除操作部３２ｂの端部で係止する。そのハウジング側係止部３１ｂと解除操作部３２ｂの端部とを利用して、完全嵌合状態でのロックアーム３１の嵌合方向側への動きが規制される。 In the lock arm 31, as shown in FIG. 10, the housing-side locking portion 31b moves closer to the release operation portion 32b by moving in the fitting direction to the position where the lock arm 31 is in the completely fitted state. Between the housing-side engaging portion 31b and the releasing operation portion 32b, the movement of the housing-side engaging portion 31b in the fitting direction is suppressed by narrowing the gap at the position where the fully engaged state is achieved. The end of 32b is locked. The housing-side engaging portion 31b and the end portion of the release operation portion 32b are used to restrict the movement of the lock arm 31 in the fitting direction in the completely fitted state.

次に、検知部材４０における、固定位置から本係止位置への相対移動について説明する。図８に示すように、完全嵌合状態において、検知部材４０が固定位置の状態で、先端部４２ａを、ハウジング側係止部３１ｂを越えて嵌合方向側に動かすことにより、検知部材４０は、固定位置から本係止位置へとハウジング２０に対して相対移動する。これにより、検知アーム４２がロック用壁部２５ａとハウジング側係止部３１ｂとの間に位置する。また、検知部材４０は、固定位置から本係止位置へとハウジング２０に対して相対移動する際に、図１２に示すように、各側壁部２５ｂの規制機構側係止部２６に対して各規制機構側被係止部４８が嵌合方向に当接する。さらに、検知部材４０は、固定位置から本係止位置へとハウジング２０に対して相対移動する際に、ロック用壁部２５ａに対してロック用壁部側端部４３ａが当接して検知部材４０を第二方向側に押し下げていくが、ガイドレール部２８に対して本体部側突起部４９が当接していないので、検知部材４０の操作荷重に対して影響を与えることはない。検知部材４０を本係止位置に移動させると、検知部材４０の規制機構側被係止部４８が規制機構側係止部２６より嵌合方向側に移動すると共に、ガイドレール部２８に対して本体部側突起部４９が対向方向において当接する。このとき、図１１に示すように、配列方向から見た場合、対向方向においてロック用壁部２５ａとガイドレール部２８との間で検知部材４０を挟み込んでいる状態となる。検知部材４０は、先端部４２ａの係止状態が解除されてから本係止位置へと移動するまでの間に、先端部４２ａが解除操作部３２ｂから離れていくので、この検知アーム４２の撓みが徐々に解消されていく。 Next, the relative movement of the detection member 40 from the fixed position to the final locking position will be described. As shown in FIG. 8, in the completely fitted state, when the detection member 40 is in the fixed position, the tip portion 42a is moved in the fitting direction beyond the housing-side locking portion 31b. , relative to the housing 20 from the fixed position to the fully locked position. As a result, the detection arm 42 is positioned between the locking wall portion 25a and the housing-side engaging portion 31b. Further, when the detection member 40 moves relative to the housing 20 from the fixed position to the final locking position, as shown in FIG. The regulating mechanism side engaged portion 48 abuts in the fitting direction. Further, when the detecting member 40 moves relative to the housing 20 from the fixed position to the final locking position, the locking wall side end portion 43a abuts against the locking wall portion 25a, thereby causing the detecting member 40 to move. is pushed down in the second direction, the operating load of the detection member 40 is not affected because the main body side projection 49 does not contact the guide rail 28 . When the detection member 40 is moved to the full locking position, the regulation mechanism side locked portion 48 of the detection member 40 moves toward the fitting direction side from the regulation mechanism side locking portion 26 and moves toward the guide rail portion 28 . The main-body-side protrusions 49 come into contact with each other in the opposing direction. At this time, as shown in FIG. 11, when viewed from the arrangement direction, the detection member 40 is sandwiched between the lock wall portion 25a and the guide rail portion 28 in the opposing direction. Since the tip portion 42a of the detection member 40 moves away from the release operation portion 32b during the period from when the locked state of the tip portion 42a is released to when it moves to the final locking position, the bending of the detection arm 42 is reduced. is gradually eliminated.

次に、検知部材４０における、本係止位置から仮係止位置への相対移動について説明する。図１０に示すように、検知部材４０が本係止位置の状態で、作業者が解除操作面４５ａを指で離脱方向に引くことにより検知部材を離脱方向に移動させることで、その進行と共に先端部４２ａが解除操作部３２ｂに接触する。そして、その解除が進むに連れて、解除操作部３２ｂが先端部４２ａに対して第一方向に向けた力を作用させる。その際、検知部材４０においては、検知アーム４２が離脱方向側の根元を支点にして撓み始める。この検知部材４０においては、更に解除が進み、図９に示すように、先端部４２ａが解除操作部３２ｂを乗り越えることができる位置まで、検知アーム４２が撓む。先端部４２ａを、解除操作部３２ｂを越えて離脱方向側に動かすことにより、検知部材４０は、本係止位置から仮係止位置へとハウジング２０に対して相対移動する。 Next, the relative movement of the detection member 40 from the full locking position to the temporary locking position will be described. As shown in FIG. 10, when the detection member 40 is in the final locking position, the operator pulls the release operation surface 45a with a finger in the separation direction, thereby moving the detection member in the separation direction. The portion 42a contacts the release operation portion 32b. Then, as the release progresses, the release operation portion 32b applies a force in the first direction to the distal end portion 42a. At that time, in the detection member 40, the detection arm 42 begins to bend with the base on the detachment direction side as a fulcrum. The detection member 40 is further released, and as shown in FIG. 9, the detection arm 42 bends to a position where the distal end portion 42a can get over the release operation portion 32b. By moving the distal end portion 42a beyond the releasing operation portion 32b in the detachment direction, the detection member 40 moves relative to the housing 20 from the full locking position to the temporary locking position.

コネクタ１及び相手方コネクタＣにおける完全嵌合状態の解除について説明する。図１０に示すように、検知部材４０が本係止位置の状態で、作業者が解除操作面４５ａを離脱方向に引き続けることにより、ロックアーム３１の支持部３１ｄが対向方向における第二方向側に押されハウジング２０の本体部２１に当接する。そして当接後、解除操作面４５ａをさらに引くことで、てこ作用により支持部３１ｄと本体部２１の接点である支点を中心にロックアーム３１の解除レバー部３１ｃが回動するため、検知部材操作部４５が離脱方向かつ第二方向に移動する。これにより、解除レバー部３１ｃの嵌合方向側の一端に接続されたハウジング側係止部３１ｂが第一方向へと撓むため、挿抜方向でハウジング側係止部３１ｂとハウジング側被係止部３２ａとが向かい合わないようになる。このため、解除操作面４５ａを引き続けることで、コネクタ１と相手方コネクタＣの完全嵌合状態を解除でき本係止解除状態とすることができる。なお、検知部材操作部４５は、半嵌合状態において、支持部３１ｄを挟んで本体部２１に対向するとともにハウジング側係止部３１ｂより離脱方向側に位置する。 Disengagement of the completely mated state between the connector 1 and the mating connector C will be described. As shown in FIG. 10, when the detection member 40 is in the final locking position, the operator continues to pull the release operation surface 45a in the detachment direction, so that the support portion 31d of the lock arm 31 moves toward the second direction side in the opposing direction. is pressed against the main body 21 of the housing 20 . After the abutment, by further pulling the release operation surface 45a, the release lever portion 31c of the lock arm 31 rotates around the fulcrum, which is the point of contact between the support portion 31d and the main body portion 21, by lever action, thereby operating the detection member. The portion 45 moves in the detachment direction and the second direction. As a result, the housing side locking portion 31b connected to one end of the release lever portion 31c on the fitting direction side bends in the first direction, so that the housing side locking portion 31b and the housing side locked portion are separated from each other in the insertion/removal direction. 32a do not face each other. Therefore, by continuing to pull the releasing operation surface 45a, the completely mated state between the connector 1 and the mating connector C can be released, and the fully unlocked state can be obtained. In the semi-engaged state, the detection member operating portion 45 faces the main body portion 21 with the support portion 31d interposed therebetween and is positioned on the disengagement direction side of the housing-side locking portion 31b.

以上で説明した第１実施形態のコネクタ１は、ハウジング２０に組み付けられ、嵌合状態が完全嵌合状態において仮係止位置と本係止位置との間でハウジング２０に対する嵌合方向及び離脱方向に相対移動が可能な検知部材４０を有する。検知部材４０は、各検知部材壁部４３の対向方向のうちロック用壁部２５ａ側に位置し、かつ本係止位置にてロック用壁部２５ａに対して対向方向において当接するロック用壁部側端部４３ａと、各検知部材壁部４３の対向方向のうち本体部２１側に設けられ、各検知部材壁部４３から本体部２１側に突出し、かつ本係止位置において本体部２１に対して対向方向において当接する本体部側突起部４９とを有する。 The connector 1 according to the first embodiment described above is assembled to the housing 20, and when the mated state is the completely mated state, the mating direction and the disengaging direction with respect to the housing 20 are set between the temporary locking position and the full locking position. has a detection member 40 capable of relative movement. The detection member 40 is positioned on the lock wall portion 25a side in the facing direction of the detection member wall portions 43 and is in contact with the lock wall portion 25a in the facing direction at the final locking position. The side end portion 43a is provided on the main body portion 21 side in the facing direction of each detection member wall portion 43, protrudes from each detection member wall portion 43 toward the main body portion 21 side, and is attached to the main body portion 21 at the final locking position. and a main-body-side protrusion 49 that abuts in the facing direction.

上記構成により、ハウジング側係止部３１ｂとハウジング側被係止部３２ａとが嵌合方向において接触する状態において、ハウジング２０の本体部２１に対して検知部材４０の本体部側突起部４９が対向方向に当接し、かつハウジング２０のロック用壁部２５ａに対して検知部材４０のロック用壁部側端部４３ａが対向方向に当接するので、本係止位置における検知部材４０の対向方向の移動が規制される。この結果、本係止位置において、ハウジング２０に対して検知部材４０が対向方向に移動することでハウジング２０と衝突して発生する異音を抑制することができる。 With the above configuration, the body-side projecting portion 49 of the detection member 40 faces the body portion 21 of the housing 20 when the housing-side locking portion 31b and the housing-side locked portion 32a are in contact with each other in the fitting direction. Since the locking wall side end portion 43a of the detecting member 40 contacts the locking wall portion 25a of the housing 20 in the opposing direction, the detecting member 40 in the fully locked position moves in the opposing direction. is regulated. As a result, when the detection member 40 moves in the opposite direction to the housing 20 at the final locking position, it is possible to suppress the noise generated by the collision with the housing 20 .

また、本実施形態のコネクタ１は、本体部側突起部４９が、規制機構側被係止部４８からガイドレール部２８側に突出し、かつ本係止位置においてガイドレール部２８に対して対向方向においてそれぞれ当接する。これにより、ハウジング側係止部３１ｂとハウジング側被係止部３２ａとが嵌合方向において接触する状態において、ハウジング２０のガイドレール部２８に対して検知部材４０の本体部側突起部４９が対向方向に当接し、かつハウジング２０の規制機構側係止部２６に対して検知部材４０の規制機構側被係止部４８が嵌合方向に係止される。この結果、本係止位置において、ハウジング２０に対する検知部材４０の離脱方向への移動が規制されると共に、ハウジング２０に対して検知部材４０が対向方向に移動することでハウジング２０と衝突して発生する異音を抑制することができる。 Further, in the connector 1 of the present embodiment, the main-body-side projecting portion 49 projects from the restriction-mechanism-side engaged portion 48 toward the guide rail portion 28, and in the final locking position, the main-body-side projecting portion 49 projects toward the guide-rail portion 28 in the opposite direction. abut each at . As a result, when the housing-side engaging portion 31b and the housing-side engaged portion 32a are in contact with each other in the fitting direction, the main-body-side projecting portion 49 of the detection member 40 faces the guide rail portion 28 of the housing 20. , and the regulation mechanism-side engaged portion 48 of the detecting member 40 is engaged with the regulation mechanism-side engaging portion 26 of the housing 20 in the fitting direction. As a result, at the final locking position, the detection member 40 is restricted from moving in the separation direction with respect to the housing 20, and the detection member 40 moves in the opposite direction with respect to the housing 20, causing collision with the housing 20. noise can be suppressed.

また、各本体部側突起部４９の挿抜方向における幅は、図１１に示すように、配列方向からみた場合、規制機構側被係止部４８の挿抜方向における幅より狭い。これにより、検知部材４０が仮係止位置から本係止位置まで移動する際に、本体部側突起部４９がガイドレール部２８上を摺動した場合の摺動抵抗を減らすことができる。 Further, as shown in FIG. 11, the width of each main body side projecting portion 49 in the insertion/removal direction is narrower than the width in the insertion/removal direction of the restriction mechanism side engaged portion 48 when viewed from the arrangement direction. As a result, when the detection member 40 moves from the temporary locking position to the final locking position, sliding resistance when the main body side protrusion 49 slides on the guide rail 28 can be reduced.

なお、各本体部側突起部４９の挿抜方向における幅は、図１１に示すように、配列方向からみた場合、規制機構側被係止部４８の挿抜方向におけるより狭いが、これに限定されるものではなく。例えば、各本体部側突起部４９の挿抜方向における幅は、規制機構側被係止部４８の挿抜方向における幅と同じであってもよい。 As shown in FIG. 11, the width of each main body side protrusion 49 in the insertion/removal direction is narrower than that of the regulation mechanism side engaged portion 48 in the insertion/removal direction when viewed from the arrangement direction, but is limited to this. not things. For example, the width of each body portion-side protrusion 49 in the insertion/removal direction may be the same as the width of the restriction mechanism-side engaged portion 48 in the insertion/removal direction.
