Description

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

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（下記の特許文献１、２）。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。 Conventionally, in the case of a connector, a technique has been known for causing an operator or the like to determine whether or not the mating state with the mating connector is perfect. For example, the connector includes a detection member capable of relative movement with respect to the housing between the temporary locking position and the main locking position (Patent Documents 1 and 2 below). The detection member is moved from the temporary locking position to the main locking position unless the mating state between the connector and the mating connector (between the connectors) is perfect (in the so-called disengagement state). If it cannot be done and the fitting state is perfect (so-called perfect fitting state), it can be moved from the temporary locking position to the main locking position. The operator or the like can determine whether or not the fitting state between the connectors is perfect based on the relative positional relationship of the detection member with respect to such a housing.

The operation groove 24 has an operation space portion 24a, a side wall 24a _1, and a movable space portion 24b. The operation space portion 24a is a space portion in the operation groove 24 in which the detection member 40 is exposed to the outside, and is used when an operator or the like performs an operation. The operation space portion 24a has a side wall 24a ₁ . The side walls 24a ₁ are formed in pairs facing each other in the arrangement direction, and form a part of the outer wall of the housing 20. The movable space portion 24b is a space provided between the detection member 40 and the outer peripheral surface of the main body portion 21 in the operation groove 24, and communicates with the annular space portion 23 on the fitting direction side.

収容空間部２５は、図５に示すように、操作空間部２４ａよりも嵌合方向側に配置するように形成されており、操作空間部２４ａの嵌合方向側に連通している。収容空間部２５は、ロック用壁部２５ａと、側壁部２５ｂと、を有している。ロック用壁部２５ａは、上下方向において環状空間部２３側とは反対側で、本体部２１に対して上方向に対向するよう形成されており、検知部材４０の一部を収容する。側壁部２５ｂは、ロック用壁部２５ａの両端部に繋ぐよう形成されており、配列方向において対向して一対形成されている。また、ロック用壁部２５ａ及び側壁部２５ｂは、ハウジング２０の外壁の一部を成している。 As shown in FIG. 5, the accommodation space portion 25 is formed so as to be arranged on the fitting direction side with respect to the operation space portion 24a, and communicates with the fitting direction side of the operation space portion 24a. The accommodation space portion 25 has a lock wall portion 25a and a side wall portion 25b. The lock wall portion 25a is formed so as to face the main body portion 21 in the upward direction on the side opposite to the annular space portion 23 side in the vertical direction, and accommodates a part of the detection member 40. The side wall portions 25b are formed so as to be connected to both end portions of the locking wall portion 25a, and are formed in pairs facing each other in the arrangement direction. Further, the locking wall portion 25a and the side wall portion 25b form a part of the outer wall of the housing 20.

係止体２６は、図２に示すように、収容空間部２５の一対の側壁部２５ｂからそれぞれ個別に立設し、配列方向において対向して一対形成されている。一方の係止体２６は、他方の係止体２６に向けて突出させて形成されている。 As shown in FIG. 2, the locking bodies 26 are individually erected from the pair of side wall portions 25b of the accommodation space portion 25, and are formed in pairs facing each other in the arrangement direction. One locking body 26 is formed so as to project toward the other locking body 26.

ハウジング突出体２７は、図３に示すように、操作空間部２４ａの一対の側壁２４ａ_１から個別に立設し、配列方向において対向して一対形成されている。一方の突出体２７は、他方の突出体２７に向けて突出させて形成されている。本実施形態における突出体２７は、方体状に形成されている。ハウジング突出体２７は、嵌合方向から見た場合に、根元側であるハウジング突出体２７が立設している側壁２４ａ_１側よりも先端側である他方の突出体２７側が上下方向において短く、すなわち上下方向における長さである厚さが薄く形成されている。 As shown in FIG. 3, the housing protrusions 27 are individually erected from the pair of side walls 24a ₁ of the operation space portion 24a, and are formed in pairs facing each other in the arrangement direction. One projecting body 27 is formed so as to project toward the other projecting body 27. The projecting body 27 in the present embodiment is formed in a square shape. When viewed from the fitting direction, the housing projecting body 27 is shorter in the vertical direction on the other projecting body 27 side, which is the tip side than the side wall 24a ₁ side on which the housing projecting body 27 on the root side stands. That is, the thickness, which is the length in the vertical direction, is formed thin.

規制レール２８は、図２に示すように、各側壁部２５ｂにそれぞれ形成されている。規制レール２８は、検知部材４０の後述する壁体４２とそれぞれ対向するように突出しており、検知部材移動工程において、本係止用係止突起４６と上下方向と向き合うことができるように形成及び配置される。従って、検知部材４０が収容空間部２５に挿入された際に、各本係止用係止突起４６が各規制レール２８と上方向において接触することで、検知部材４０のハウジング２０に対する下方向への移動が規制される。特に、検知部材４０が本係止位置にある際に、検知部材４０を下方向に押しても、検知部材４０がハウジング２０に対する下方向への移動することが抑制されるので、上下方向において過度の荷重がかかった状態で、仮係止解除部４５が相手方ハウジングＣｈの筒状のフードＣｈｆと接触することを抑制することができる。これにより、コネクタ１の耐久性を向上することができる。 As shown in FIG. 2, the regulation rail 28 is formed on each side wall portion 25b. The regulation rail 28 projects so as to face the wall body 42 described later of the detection member 40, and is formed so as to face the locking projection 46 for locking in the vertical direction in the detection member moving step. Be placed. Therefore, when the detection member 40 is inserted into the accommodation space 25, each of the locking projections 46 for locking comes into contact with each regulation rail 28 in the upward direction, so that the detection member 40 moves downward with respect to the housing 20. Movement is restricted. In particular, even if the detection member 40 is pushed downward when the detection member 40 is in the main locking position, the detection member 40 is suppressed from moving downward with respect to the housing 20, so that it is excessive in the vertical direction. It is possible to prevent the temporary locking release portion 45 from coming into contact with the tubular hood Chf of the mating housing Ch when a load is applied. Thereby, the durability of the connector 1 can be improved.

ここで、コネクタ１と相手方コネクタＣとが互いに挿入し終えた状態であって、端子と相手方端子との間の物理的且つ電気的な接続が成立している状態を完全嵌合状態という。一方、コネクタ嵌合工程において完全嵌合状態となる前まで、あるいはコネクタ解除工程において完全嵌合状態の後におけるコネクタ１と相手方コネクタＣとの間（以下、「コネクタ間」ともいう。）の嵌合状態のことを嵌合解除状態という。 Here, a state in which the connector 1 and the mating connector C have been inserted into each other and a physical and electrical connection between the terminal and the mating terminal is established is referred to as a perfect fitting state. On the other hand, the fitting between the connector 1 and the mating connector C (hereinafter, also referred to as "connector-to-connector") before the complete fitting state in the connector fitting step or after the complete fitting state in the connector releasing step. The combined state is called the unfitted state.

図６に示すように、コネクタ１と相手方コネクタＣとの間には、これらが完全嵌合状態のときにハウジング２０と相手方ハウジングＣｈとを互いに係合させ、その完全嵌合状態を保持させる保持構造３０が設けられている。保持構造３０は、コネクタ間の所謂ロック構造であり、図６に示すように、コネクタ１と相手方コネクタＣとの嵌合状態が完全嵌合状態のときにハウジング２０と相手方ハウジングＣｈとを互いに係合させ、その完全嵌合状態を保持させる。保持構造３０は、ロックアーム３１と、被係止構造３２とからなる。 As shown in FIG. 6, between the connector 1 and the mating connector C, the housing 20 and the mating housing Ch are engaged with each other when they are in the fully fitted state, and the fully fitted state is maintained. The structure 30 is provided. The holding structure 30 is a so-called lock structure between the connectors, and as shown in FIG. 6, the housing 20 and the mating housing Ch are engaged with each other when the mating state of the connector 1 and the mating connector C is in a completely mating state. It is fitted and the fully fitted state is maintained. The holding structure 30 includes a lock arm 31 and a locked structure 32.

ロックアーム３１は、図５に示すように、本体部２１における４つの外周面の内の１つに対して一体化されるよう形成されており、相手方ハウジングＣｈに係止されることで、完全嵌合状態を保持させる。ロックアーム３１は、本体部２１に固定されるものであり、可撓性を持たせており、検知部材４０を取り付け可能となっている。また、ロックアーム３１は、基部３１ａ、係止部３１ｂ、解除レバー部３１ｃ、支持部３１ｄ、ガイド部３１ｆ、ロックアーム突出体３１ｇを有している。 As shown in FIG. 5, the lock arm 31 is formed so as to be integrated with one of the four outer peripheral surfaces of the main body 21, and is completely locked by the mating housing Ch. Hold the mated state. The lock arm 31 is fixed to the main body 21 and has flexibility so that the detection member 40 can be attached. Further, the lock arm 31 has a base portion 31a, a locking portion 31b, a release lever portion 31c, a support portion 31d, a guide portion 31f, and a lock arm projecting body 31g.

基部３１ａは、離脱方向側の一端が下方に曲がって本体部２１の上方向側の外周面に固定され、かつ嵌合方向側の他端が嵌合方向に延在するよう形成されている。 The base portion 31a is formed so that one end on the detaching direction side is bent downward and fixed to the outer peripheral surface on the upward side of the main body portion 21, and the other end on the fitting direction side extends in the fitting direction.

係止部３１ｂは、基部３１ａの嵌合方向側の他端に形成され、ロック用壁部２５ａと下方向において対向するように形成されている。係止部３１ｂは、相手方ハウジングＣに設けられた被係止部３２ａに係止するものであり、係止を解除可能に、相手方ハウジングＣをハウジング２０に対してロックするものである。 The locking portion 31b is formed at the other end of the base portion 31a on the fitting direction side, and is formed so as to face the locking wall portion 25a in the downward direction. The locking portion 31b locks to the locked portion 32a provided on the mating housing C, and locks the mating housing C to the housing 20 so that the locking can be released.

解除レバー部３１ｃは、嵌合方向側の一端が係止部３１ｂに接続され、離脱方向側の他端が離脱方向に延在するよう形成されている。解除レバー部３１ｃは、ロックアーム３１の両側壁が嵌合方向に延びる半矢じり形状に形成されており、この側壁を構成している。解除レバー部３１ｃは、上下方向から見た場合に、ロックアーム３１の両側壁の離脱方向側の他端が連結部３１ｉにより連結されることで構成されている。また、解除レバー部３１ｃは、支持部３１ｄと接触部３１ｈとを有している。 The release lever portion 31c is formed so that one end on the fitting direction side is connected to the locking portion 31b and the other end on the release direction side extends in the release direction. The release lever portion 31c is formed in a half arrowhead shape in which both side walls of the lock arm 31 extend in the fitting direction, and constitutes the side wall thereof. The release lever portion 31c is configured such that the other ends of both side walls of the lock arm 31 on the detachment direction side are connected by the connecting portion 31i when viewed from the vertical direction. Further, the release lever portion 31c has a support portion 31d and a contact portion 31h.

支持部３１ｄは、ハウジング２０単体での状態において、本体部２１との間に隙間が形成されている。支持部３１ｄは、本体部２１の外周面と上下方向に対向するものであり、配列方向から見た場合に、基部３１ａの離脱方向側の一端と重なるよう形成されている。 A gap is formed between the support portion 31d and the main body portion 21 in the state of the housing 20 alone. The support portion 31d faces the outer peripheral surface of the main body portion 21 in the vertical direction, and is formed so as to overlap one end of the base portion 31a on the detachment direction side when viewed from the arrangement direction.

接触部３１ｈは、ロックアーム３１が弾性変形をすることで、支持部３１ｄが本体部２１の外周面と接触した直後には本体部２１の外周面と接触せず、ロックアーム３１がさらに弾性変形することで、本体部２１の外周面と接触するものである。ロックアーム３１は、接触部３１ｈが本体部２１の外周面と接触することで、下方向側への弾性変形が規制されるので、ロックアーム３１の過度の撓みを抑制することができ、ロックアーム３１が塑性することを抑制することができる。ここで、解除レバー部３１ｃの下方向側端面は、幅方向から見た場合に、接触部３１ｈと支持部３１ｄとを結んだ直線よりも、上方向側に突出する湾曲面であることが好ましい。これにより、支持部３１ｄが本体部２１の外周面と接触したのち、接触部３１ｈが本体部２１の外周面と接触する前に、下方向側他面と接触することが抑制できる。 Since the lock arm 31 is elastically deformed , the contact portion 31h does not come into contact with the outer peripheral surface of the main body 21 immediately after the support portion 31d comes into contact with the outer peripheral surface of the main body 21, and the lock arm 31 is further elastically deformed. By doing so, it comes into contact with the outer peripheral surface of the main body 21. Since the contact portion 31h of the lock arm 31 comes into contact with the outer peripheral surface of the main body portion 21 to regulate the elastic deformation downward, the lock arm 31 can suppress excessive bending of the lock arm 31. It is possible to prevent 31 from plasticizing. Here, the downward end surface of the release lever portion 31c is preferably a curved surface that projects upward from the straight line connecting the contact portion 31h and the support portion 31d when viewed from the width direction. .. As a result, it is possible to prevent the support portion 31d from coming into contact with the outer peripheral surface of the main body 21, and then the contact portion 31h from coming into contact with the other surface on the downward side before coming into contact with the outer peripheral surface of the main body 21.

The guide portion 31f of the present embodiment is provided on the release lever portion 31c.

ロックアーム突出体３１ｇは、図３に示すように、側壁２４ａ_１に向かい合うよう方体状に一対形成されている。本実施形態のロックアーム突起体３１ｇは、解除レバー部３１ｃに設けられている。ロックアーム突出体３１ｇは、嵌合方向から見た場合に、根元側である解除レバー部３１側よりも先端側である対向する側壁２４ａ_１側が上下方向において短く、すなわち上下方向における長さである厚さが薄く形成されている。 As shown in FIG. 3, the lock arm projecting bodies 31g are formed in a pair in a square shape so as to face the side wall 24a ₁ . The lock arm protrusion 31g of the present embodiment is provided on the release lever portion 31c.

The locked portion 32a is formed with respect to the outer wall surface of the hood Chf so as to be located on the side in the disengagement direction with respect to the locking portion 31b in the completely fitted state. The locking portion 31b and the locked portion 32a may be brought into contact with each other in the insertion / removal direction in the completely fitted state, or may be spaced apart in the insertion / removal direction. However, when there is a gap, the gap is set so that the perfect fitting state is not impaired when the gap is narrowed and the locking portion 31b and the locked portion 32a come into contact with each other. The locked portion 32a of this example is formed in a square shape.

解除操作部３２ｂは、図１に示すように、フードＣｈｆの外壁面から突出させた突出体であり、コネクタ嵌合工程において、挿抜方向において係止部３１ｂと向き合うことができるように形成されている。解除操作部３２ｂは、完全嵌合状態のときに、係止部３１ｂよりも嵌合方向側に位置するように、フードＣｈｆの外壁面に対して形成されている。係止部３１ｂおよび解除操作部３２ｂは、完全嵌合状態のときに、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。この例示の解除操作部３２ｂは、方体状に形成されており、嵌合方向側に斜面が形成されている。 As shown in FIG. 1, the release operation portion 32b is a projecting body protruding from the outer wall surface of the hood Chf, and is formed so as to face the locking portion 31b in the insertion / removal direction in the connector fitting step. There is. The release operation portion 32b is formed with respect to the outer wall surface of the hood Chf so as to be located on the fitting direction side with respect to the locking portion 31b in the completely fitted state. The locking portion 31b and the releasing operation portion 32b may be brought into contact with each other in the insertion / removal direction in the fully fitted state, or may be spaced apart in the insertion / removal direction. The release operation portion 32b of this example is formed in a square shape, and a slope is formed on the fitting direction side.

本実施形態のコネクタ１は、図６に示すように、挿抜方向においてハウジング２０に対して相対移動が可能に形成され、作業者等が相手方コネクタＣとの完全嵌合状態を判断するための検知部材４０を有する。検知部材４０は、ロックアーム３１に組み付ける。検知部材４０は、ロックアーム３１よりもハウジング２０の外方寄りに配置され、かつ、少なくとも離脱方向側が操作溝２４の操作空間部２４ａに配置されるように、ハウジング２０に対して組み付ける。従って、操作空間部２４ａにおいては、検知部材４０の少なくとも離脱方向側が外部に露出している。本実施形態のコネクタ１においては、操作空間部２４ａを検知部材４０の相対移動操作のための空間としても利用する。このため、検知部材４０においては、離脱方向側が相対移動操作のための操作部として利用される。また、検知部材４０は、基体４１、壁体４２、被ガイド部４３、検知部材操作部４４、仮係止解除部４５、本係止用係止突起４６、検知部材突起体４７、規制突起体４８を有している。 As shown in FIG. 6, the connector 1 of the present embodiment is formed so as to be relatively movable with respect to the housing 20 in the insertion / removal direction, and a detection for an operator or the like to determine a completely fitted state with the mating connector C. It has a member 40. The detection member 40 is assembled to the lock arm 31. The detection member 40 is assembled to the housing 20 so that it is arranged closer to the outside of the housing 20 than the lock arm 31 and at least the side in the detaching direction is arranged in the operation space portion 24a of the operation groove 24. Therefore, in the operation space portion 24a, at least the detachment direction side of the detection member 40 is exposed to the outside. In the connector 1 of the present embodiment, the operation space portion 24a is also used as a space for the relative movement operation of the detection member 40. Therefore, in the detection member 40, the detachment direction side is used as an operation unit for the relative movement operation. Further, the detection member 40 includes a base 41, a wall body 42, a guided portion 43, a detection member operation portion 44, a temporary locking release portion 45, a locking projection 46 for main locking, a detection member projection 47, and a regulation projection. Has 48.

基体４１は、図７に示すように、ハウジング２０に対して検知部材４０を取り付けた後に、ロックアーム３１の基部３１ａに対して間隔を空けて配置されるよう形成されている。基体４１は、例えば、一方の平面を下方向で基部３１ａに向かい合わせた矩形の片体形状の成形体であってもよく、その片体形状の成形体に様々な切欠きや溝等を形成したものであってもよい。 As shown in FIG. 7, the base 41 is formed so as to be arranged at intervals with respect to the base portion 31a of the lock arm 31 after the detection member 40 is attached to the housing 20. The substrate 41 may be, for example, a rectangular piece-shaped molded body having one plane facing downward toward the base portion 31a, and various notches, grooves, or the like are formed in the piece-shaped molded body. It may be the one that has been used.

壁体４２は、基体４１の配列方向の両端部からそれぞれの側壁２４ａ_１側に向かって一対形成されている。被ガイド部４３は、壁体４２の先端にそれぞれ形成されており、検知部材移動工程において、嵌合方向でロックアーム３１のガイド部３１ｆと向き合うことができるように形成及び配置され、ガイド部３１ｆと被ガイド部４３との係止により、ハウジング２０に対する検知部材４０の嵌合方向への相対移動を案内する。本実施形態では、ロックアーム３１に検知部材４０を取り付け、この検知部材４０とロックアーム３１との間にガイド部３１ｆと被ガイド部４３からなるガイド構造５１を設ける。このガイド構造５１においては、解除レバー部３１ｃにガイド部３１ｆとしてのガイド溝を設けると共に、検知部材４０に被ガイド部４３としてのガイド突起を設ける。また、各壁体４２は、側壁２４ａ_１側の面に案内面４２ａがそれぞれ形成されている。各案内面４２ａは、下方向に向かうにともない、側壁２４ａ_１側と反対側に向かう傾斜面である。各案内面４２ａは、検知部材４０をハウジング２０に挿入する際において、被ガイド部４３がガイド部３１ｆを下方向に乗り越える時に、側壁２４ａ_１と接触するように形成されている。従って、権利部材４０は被ガイド部４３がガイド部３１ｆを下方向に乗り越える時に、各壁体４２が側壁２４ａ_１側に向かって幅方向に広がるが、その際に案内面４２ａが側壁２４ａ_１に接触することとなるので、ハウジング２０に対する検知部材４０を挿入を容易に行うことができる。 The wall bodies 42 are formed in pairs from both ends of the base 41 in the arrangement direction toward the side walls 24a ₁ side. The guided portion 43 is formed at the tip of the wall body 42, and is formed and arranged so as to face the guide portion 31f of the lock arm 31 in the fitting direction in the detection member moving step. And the guided portion 43 are engaged with each other to guide the relative movement of the detection member 40 with respect to the housing 20 in the fitting direction. In the present embodiment, the detection member 40 is attached to the lock arm 31, and a guide structure 51 including a guide portion 31f and a guided portion 43 is provided between the detection member 40 and the lock arm 31. In the guide structure 51, the release lever portion 31c is provided with a guide groove as the guide portion 31f, and the detection member 40 is provided with a guide protrusion as the guided portion 43. Further, each wall body 42 has a guide surface 42a formed on a surface on the side wall 24a ₁ side. Each guide surface 42a is an inclined surface that faces the side opposite to the side wall 24a ₁ side as it goes downward. Each guide surface 42a is formed so as to come into contact with the side wall 24a ₁ when the guided portion 43 gets over the guide portion 31f downward when the detection member 40 is inserted into the housing 20. Therefore, when the guided portion 43 gets over the guide portion 31f downward, each wall body 42 of the right member 40 expands in the width direction toward the side wall 24a ₁ side, and at that time, the guide surface 42a becomes the side wall 24a ₁ . Since they come into contact with each other, the detection member 40 can be easily inserted into the housing 20.

検知部材操作部４４は、図１に示すように、操作空間部２４ａにおいて、上方向に基体４１から突出させるよう形成されており、検知部材４０の相対移動を作業者等が行う際に利用される。検知部材操作部４４は、ハウジング２０のロック用壁部２５ａよりも外方に突出させ、解除操作面４４ａと、嵌合操作面４４ｂと、を有している。解除操作面４４ａは、嵌合方向側に位置し、離脱方向と向かい合うよう形成されており、嵌合操作面４４ｂは、離脱方向側に位置し、嵌合方向と向かい合うよう形成されている。嵌合操作面４４ｂは、図５に示すように、嵌合操作部４４の上方向側端面から下方向に向かうにともない離脱方向側に突出する傾斜面として形成されている。検知部材４０を嵌合方向に移動させる際に、作業者は、嵌合操作面４４ｂを嵌合方向に押すこととなるが、嵌合操作面が傾斜面となっているため、検知部材４０は嵌合方向および下方向に向かう力が作用することとなる。従って、検知部材４０を嵌合方向に移動させる際に、仮係止解除部４５が上方向に浮き上がることを抑制することができる。なお、嵌合操作面４４ｂは、上下方向において複数の凹部が連続して形成されていてもよい。各凹部は、幅方向から見た場合に、下方向側に位置する第一凹部面と、上方向側に位置する第二凹部面とを有し、第一凹部面の長さが第二凹部面よりも長く形成されている。また、第一凹部面は、嵌合操作面４４ｂ全体の傾斜角度よりも深く、すなわち嵌合方向側に向かう傾斜面に形成されている。検知部材操作部４４は、係止解除位置において、支持部３１ｄを挟んで本体部２１に対向するとともに係止部３１ｂより離脱方向側に位置するように、形成されている。 As shown in FIG. 1, the detection member operation unit 44 is formed so as to protrude upward from the base 41 in the operation space unit 24a, and is used when an operator or the like relatively moves the detection member 40. To. The detection member operation unit 44 is projected outward from the lock wall portion 25a of the housing 20, and has a release operation surface 44a and a fitting operation surface 44b. The release operation surface 44a is located on the fitting direction side and is formed so as to face the detaching direction, and the fitting operation surface 44b is located on the detaching direction side and is formed so as to face the fitting direction. As shown in FIG. 5, the fitting operation surface 44b is formed as an inclined surface that projects downward from the upward side end surface of the fitting operation portion 44 in the detaching direction side. When moving the detection member 40 in the fitting direction, the operator pushes the fitting operation surface 44b in the fitting direction, but since the fitting operation surface is an inclined surface, the detection member 40 Forces acting in the mating direction and downward will act. Therefore, when the detection member 40 is moved in the fitting direction, it is possible to prevent the temporary locking release portion 45 from being lifted upward. The fitting operation surface 44b may have a plurality of recesses continuously formed in the vertical direction. Each recess has a first recess surface located on the lower side and a second recess surface located on the upper side when viewed from the width direction, and the length of the first recess surface is the second recess. It is formed longer than the surface. Further, the first concave surface is formed to be deeper than the inclination angle of the entire fitting operation surface 44b, that is, an inclined surface toward the fitting direction side. The detection member operating portion 44 is formed so as to face the main body portion 21 with the support portion 31d interposed therebetween and to be located on the disengagement direction side from the locking portion 31b at the unlocking position.

仮係止解除部４５は、図７に示すように、基体４１の嵌合方向側の端部から本体部２１に向けて突出させるよう形成されており、検知部材移動工程において、嵌合方向でロックアーム３１の係止部３１ｂと向き合うことができるように形成及び配置される。 As shown in FIG. 7, the temporary locking release portion 45 is formed so as to project from the end portion of the base 41 on the fitting direction side toward the main body portion 21, and is formed in the fitting direction in the detection member moving step. It is formed and arranged so as to face the locking portion 31b of the lock arm 31.

本係止用係止突起４６は、図３に示すように、検知部材４０の各壁体４２の嵌合方向側にそれぞれ形成されている。本係止用係止突起４６は、ハウジング２０のそれぞれの側壁部２５ｂに対向するように突出しており、検知部材移動工程において、嵌合方向でハウジング２０の係止体２６と向き合うことができるように形成及び配置される。 As shown in FIG. 3, the locking projections 46 for locking are formed on the fitting direction side of each wall body 42 of the detection member 40. The locking projections 46 for locking project so as to face each side wall portion 25b of the housing 20 so that they can face the locking body 26 of the housing 20 in the fitting direction in the detection member moving step. Formed and placed in.

検知部材突出体４７は、図３および図７に示すように、側壁２４ａ_１に向かい合うよう方体状に一対形成されている。本実施形態の検知部材突出体４７は、検知部材操作部４４に設けられている。検知部材突出体４７は、嵌合方向から見た場合に、根元側である検知部材操作部４４側よりも先端側である対向する側壁２４ａ_１側が上下方向において短く、すなわち上下方向における長さである厚さが薄く形成されている。ここで、検知部材突起部４７は、検知部材４０が係止解除位置において、上方向においてハウジング突出体２７と対向し、下方向においてロックアーム突出体３１ｇと対向する。つまり、検知部材突出体４７は、係止解除位置において上下方向においてハウジング突出体２７とロックアーム突出体３１ｇとに挟まれる。このとき、検知部材突出体４７の先端側は、上下方向においてハウジング突出体２７およびロックアーム突出体３１ｇの根元側に位置することとなる。従って、嵌合方向から見た場合に、ハウジング突出体２７、ロックアーム突出体３１ｇおよび検知部材突出体４７を合わせた上下方向における長さは、ハウジング突出体２７、ロックアーム突出体３１ｇおよび検知部材突出体４７が矩形形状である場合と比較して、短くすることができる。これにより、コネクタ１の上下方向における長さを抑制することができ、コネクタ１の小型化を図ることができる。 As shown in FIGS. 3 and 7, a pair of detection member projecting bodies 47 are formed in a square shape so as to face the side wall 24a ₁ . The detection member projecting body 47 of the present embodiment is provided in the detection member operation unit 44. Detecting member projecting member 47, when viewed from the mating direction, the side wall 24a ₁ side which faces a front end side of the detection member operation portion 44 side is a base side is short in the vertical direction, i.e. the length in the vertical direction A certain thickness is formed thin. Here, the detection member protrusion 47 faces the housing protrusion 27 in the upward direction and the lock arm protrusion 31g in the downward direction when the detection member 40 is in the unlocked position. That is, the detection member projecting body 47 is sandwiched between the housing projecting body 27 and the lock arm projecting body 31g in the vertical direction at the unlocking position. At this time, the tip end side of the detection member projecting body 47 is located on the root side of the housing projecting body 27 and the lock arm projecting body 31g in the vertical direction. Therefore, when viewed from the fitting direction, the total length of the housing protrusion 27, the lock arm protrusion 31g, and the detection member protrusion 47 in the vertical direction is the housing protrusion 27, the lock arm protrusion 31g, and the detection member. It can be shortened as compared with the case where the projecting body 47 has a rectangular shape. As a result, the length of the connector 1 in the vertical direction can be suppressed, and the size of the connector 1 can be reduced.

規制突起体４８は、図６および図７に示すように、基体４１の下方向側の面である下面から下方向に突出して形成されている。規制突起体４８は、基体４１の下面のうち、検知部材４０が本係止位置において、上下方向から見た場合に、係止部３１ｂあるいは被係止部３２の少なくとも一方の一部と重なる位置に形成されている。従って、規制突起体４８は、検知部材４０が本係止位置において、一部が係止部３１ｂあるいは被係止部３２のいずれかと重なるので、規制突起体４８がない場合と比較して、上下方向における検知部材４０との隙間を狭くすることができる。これにより、完全嵌合状態において係止部３１ｂが被係止部３２ａを離脱方向に乗り越えようとしても、上下方向において係止部３１ｂが規制突起体４８と接触することとなり、係止部３１ｂが被係止部３２ａを離脱方向に乗り越えることが抑制されるので、完全嵌合状態を確実に維持することができる。 As shown in FIGS. 6 and 7, the regulation protrusion 48 is formed so as to project downward from the lower surface, which is the lower surface of the substrate 41. The regulation protrusion 48 is located on the lower surface of the substrate 41 so that the detection member 40 overlaps at least one part of the locking portion 31b or the locked portion 32 when viewed from above and below at the main locking position. Is formed in. Therefore, since the detection member 40 partially overlaps with either the locking portion 31b or the locked portion 32 at the main locking position, the regulating protrusion 48 is moved up and down as compared with the case where the regulating protrusion 48 is not provided. The gap with the detection member 40 in the direction can be narrowed. As a result, even if the locking portion 31b tries to get over the locked portion 32a in the disengaging direction in the completely fitted state, the locking portion 31b comes into contact with the regulating protrusion 48 in the vertical direction, and the locking portion 31b Since it is suppressed from getting over the locked portion 32a in the disengagement direction, the completely fitted state can be reliably maintained.

検知部材４０は、ハウジング２０に対して仮係止位置、本係止位置及び解除位置との間で相対移動（検知部材移動工程）させることができる。仮係止位置とは、コネクタ１と相手方コネクタＣとの間の嵌合状態が嵌合解除状態のときのハウジング２０に対する検知部材４０の位置のことであり、検知部材４０がロック用壁部２５ａと係止部３１ｂとの間に位置しない位置である。本実施形態における仮係止位置は、係止解除位置でもある。この例示の仮係止位置及び係止解除位置は、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、仮係止位置はコネクタ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おり、係止解除位置はコネクタ１と相手方コネクタＣとが互いに離脱された後の状態も含まれている。本係止位置は、コネクタ１と相手方コネクタＣとの間の嵌合状態が完全嵌合状態のときのハウジング２０に対する検知部材４０の位置のことであり、検知部材４０の少なくとも一部がロック用壁部２５ａと係止部３１ｂとの間に位置する位置である。本実施形態における検知部材４０は、ハウジング２０に対して挿抜方向に相対移動し得るものであり、仮係止位置から嵌合方向へと相対移動させることで本係止位置まで到達し、本係止位置から離脱方向へ相対移動させることで、係止解除位置まで到達する。 The detection member 40 can be moved relative to the housing 20 between the temporary locking position, the main locking position, and the releasing position (detection member moving step). The temporary locking position is the position of the detection member 40 with respect to the housing 20 when the mating state between the connector 1 and the mating connector C is the unfitting state, and the detection member 40 is the locking wall portion 25a. It is a position that is not located between the locking portion 31b and the locking portion 31b. The temporary locking position in the present embodiment is also the unlocking position. The temporary locking position and the unlocking position in this example are also positions when the detection member 40 is assembled to the housing 20. Therefore, the temporary locking position includes the state before the connector 1 and the mating connector C are inserted into each other, and the unlocking position also includes the state after the connector 1 and the mating connector C are separated from each other. include. This locking position is the position of the detection member 40 with respect to the housing 20 when the mating state between the connector 1 and the mating connector C is in the completely mating state, and at least a part of the detection member 40 is for locking. It is a position located between the wall portion 25a and the locking portion 31b. The detection member 40 in the present embodiment can move relative to the housing 20 in the insertion / extraction direction, and reaches the main locking position by relatively moving from the temporary locking position to the fitting direction. By moving relative to the release direction from the stop position, the lock release position is reached.

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５に示すように、検知部材４０が仮係止位置の状態で、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係止部３１ｂと被係止部３２ａとが当接する。係止部３１ｂ及び被係止部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、係止部３１ｂが被係止部３２ａによって上方向へと押動され、ロックアーム３１を撓ませながら係止部３１ｂが完全嵌合状態となる位置まで被係止部３２ａを乗り越える。また、作業者等は、ロックアーム３１における係止部３１ｂを上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、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, the fitting of the connector 1 and the mating connector C will be described. As shown in FIG. 5, with the detection member 40 in the temporarily locked position, the connector 1 is moved in the fitting direction so as to insert the mating housing Ch into the annular space 23 of the housing 20. As the connector 1 moves in the mating direction, the locking portion 31b and the locked portion 32a come into contact with each other. After the locking portion 31b and the locked portion 32a come into contact with each other, the connector 1 continues to move in the mating direction, so that the locking portion 31b is pushed upward by the locked portion 32a and locked. While bending the arm 31, the locked portion 32a is overcome to a position where the locking portion 31b is in a completely fitted state. Further, the operator or the like bends the locking portion 31b of the lock arm 31 upward, and then the connector 1 continues to move in the fitting direction, so that the locked portion 32a is in a completely fitted state. You may move it to the position.

なお、被係止部３２ａが係止部３１ｂを上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、仮係止解除部４５が被係止部３２ａに接触する。そして、コネクタ１の嵌合方向への移動が進むことで、被係止部３２ａが仮係止解除部４５に対して上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、基体４１が離脱方向側の根元を支点にして撓み始める。 After the locked portion 32a pushes the locked portion 31b upward, the connector 1 continues to move in the mating direction, so that the temporarily locked release portion 45 comes into contact with the locked portion 32a. .. Then, as the connector 1 moves in the fitting direction, the locked portion 32a exerts an upward force on the temporarily locked release portion 45. At that time, in the detection member 40, the base 41 begins to bend with the root on the detachment direction side as a fulcrum.

完全嵌合状態となる位置では、図９に示すように、撓ませられていたロックアーム３１が弾性復帰し、挿抜方向において係止部３１ｂと被係止部３２ａとが向かい合うことになる。保持構造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、仮係止解除部４５が係止部３１ｂを乗り越えることができる位置まで、基体４１が撓む。 At the position where the fully fitted state is reached, as shown in FIG. 9, the bent lock arm 31 elastically returns, and the locking portion 31b and the locked portion 32a face each other in the insertion / removal direction. In the holding structure 30, since the pulling-out operation between the connector 1 and the mating connector C is suppressed, the holding structure 30 is held in a completely fitted state. Further, in the detection member 40, the base 41 bends to a position where the temporary locking release portion 45 can get over the locking portion 31b.

ロックアーム３１においては、図９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、係止部３１ｂが解除操作部３２ｂに近づいていく。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、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、完全嵌合状態におけるロックアーム３１の嵌合方向側への移動が規制される。 In the lock arm 31, as shown in FIG. 9, the locking portion 31b approaches the releasing operation portion 32b by moving in the fitting direction to a position where the lock arm 31 is in a completely fitted state. By narrowing the distance between the locking portion 31b and the releasing operation portion 32b at the position where the locking portion 31b is in a completely fitted state, the movement of the locking portion 31b toward the fitting direction is prevented from the end portion of the releasing operating portion 32b. Lock with. The movement of the lock arm 31 toward the fitting direction in the fully fitted state is restricted by using the locking portion 31b and the end portion of the releasing operation portion 32b.

次に、仮係止位置における、ハウジング２０に対する検知部材４０の相対移動方向への移動の規制について説明する。検知部材４０とハウジング２０との間には、図５に示すように、ハウジング２０に対する検知部材４０の相対移動方向（挿抜方向）への移動を仮係止位置で規制する仮係止構造が設けられている。仮係止構造は、ロックアーム突出体３１ｇ及び壁体４２により、検知部材４０の離脱方向側への動きを係止するとともに、係止部３１ｂ及び仮係止解除部４５により、検知部材４０の嵌合方向側への動きを係止する。 Next, regulation of movement of the detection member 40 with respect to the housing 20 in the relative movement direction at the temporary locking position will be described. As shown in FIG. 5, a temporary locking structure is provided between the detection member 40 and the housing 20 to regulate the movement of the detection member 40 with respect to the housing 20 in the relative movement direction (insertion / extraction direction) at the temporary locking position. Has been done. In the temporary locking structure, the movement of the detection member 40 toward the detachment direction is locked by the lock arm projecting body 31g and the wall body 42, and the detection member 40 is locked by the locking portion 31b and the temporary locking release portion 45. Locks the movement toward the mating direction.

検知部材４０の離脱方向側への移動を仮係止位置で規制する構造について説明する。ロックアーム突出体３１ｇは、図３に示すように、壁体４２よりも離脱方向側に配置し、壁体４２の離脱方向側の端部に対して挿抜方向で対向させることにより、壁体４２の離脱方向側への移動をロックアーム突出体３１ｇで規制する。ロックアーム突出体３１ｇと壁体４２とによって、仮係止位置でのロックアーム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。ロックアーム突出体３１ｇと壁体４２は、検知部材４０が仮係止位置のときに、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。 A structure for restricting the movement of the detection member 40 in the detachment direction side at the temporary locking position will be described. As shown in FIG. 3, the lock arm projecting body 31g is arranged on the detaching direction side of the wall body 42, and is opposed to the end portion of the wall body 42 on the detaching direction side in the insertion / removal direction. The movement of the lock arm in the detaching direction side is restricted by the lock arm projecting body 31 g. The lock arm projecting body 31g and the wall body 42 restrict the movement of the detection member 40 with respect to the lock arm 31 (housing 20) at the temporarily locked position in the detaching direction side. The lock arm projecting body 31g and the wall body 42 may be brought into contact with each other in the insertion / removal direction when the detection member 40 is in the temporary locking position, or may be spaced apart in the insertion / removal direction.

検知部材４０の嵌合方向側への移動を仮係止位置で規制する構造について説明する。仮係止解除部４５は、相手方コネクタＣが挿入される前の仮係止位置において、その収容空間部２５の中で嵌合方向側への移動を規制する。係止部３１ｂは、図５に示すように、相手方コネクタＣが挿入される前で且つ検知部材４０が仮係止位置のときに、仮係止解除部４５に対して挿抜方向で対向させるように配置することにより、仮係止解除部４５の嵌合方向側への移動を規制する。係止部３１ｂと仮係止解除部４５とによって、相手方コネクタＣが挿入される前で且つ検知部材４０が仮係止位置のときに、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。係止部３１ｂと仮係止解除部４５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。 A structure for restricting the movement of the detection member 40 in the mating direction side at the temporary locking position will be described. The temporary locking release portion 45 regulates the movement of the temporary locking release portion 45 in the accommodation space portion 25 toward the fitting direction at the temporary locking position before the mating connector C is inserted. As shown in FIG. 5, the locking portion 31b is opposed to the temporary locking release portion 45 in the insertion / removal direction before the mating connector C is inserted and when the detection member 40 is in the temporary locking position. By arranging it in, the movement of the temporary locking release portion 45 toward the fitting direction is restricted. By the locking portion 31b and the temporary locking release portion 45, the detection member 40 is fitted to the lock arm 31 (housing 20) before the mating connector C is inserted and when the detection member 40 is in the temporary locking position. Regulate movement in the direction. At that time, the locking portion 31b and the temporary locking releasing portion 45 may be brought into contact with each other in the insertion / removal direction, or may be spaced apart in the insertion / removal direction.

次に、検知部材４０における、仮係止位置から本係止位置への相対移動について説明する。図９に示すように、完全嵌合状態において、検知部材４０が仮係止位置の状態で、仮係止解除部４５を、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、仮係止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、検知部材４０の一部である基体４１がロック用壁部２５ａと係止部３１ｂとの間に位置する。 Next, the relative movement of the detection member 40 from the temporary locking position to the main locking position will be described. As shown in FIG. 9, in the fully fitted state, the detection member 40 is in the temporarily locked position, and the temporary locking release portion 45 is moved beyond the locking portion 31b toward the mating direction for detection. The member 40 moves relative to the housing 20 from the temporary locking position to the main locking position. As a result, the substrate 41, which is a part of the detection member 40, is located between the locking wall portion 25a and the locking portion 31b.

また、検知部材４０の側壁２４ａ_１側の端部には、基体４１と壁体４２と被ガイド部４３とによって囲まれた挿抜方向に沿う溝が形成される。検知部材４０は、ロックアーム３１に組み付けられた際に、そのロックアーム３１が検知部材４０の溝に収容されることで、ロックアーム３１に保持されている。このように構成することによって、検知部材４０のロックアーム３１に対する挿抜方向への相対移動に際して案内が可能になるとともに、検知部材４０の３１からの離脱（相対移動方向とは異なる向きへの離脱）を抑制することができる。 Further, a groove along the insertion / removal direction surrounded by the base 41, the wall body 42, and the guided portion 43 is formed at the end portion of the detection member 40 on the side wall 24a ₁ side. When the detection member 40 is assembled to the lock arm 31, the lock arm 31 is accommodated in the groove of the detection member 40 and is held by the lock arm 31. With this configuration, it is possible to guide the detection member 40 when it moves relative to the lock arm 31 in the insertion / removal direction, and the detection member 40 is separated from 31 (separation in a direction different from the relative movement direction). Can be suppressed.

次に、本係止位置における、ハウジング２０に対する検知部材４０の相対移動方向への移動の規制について説明する。検知部材４０とハウジング２０との間には、図６に示すように、ハウジング２０に対する検知部材４０の相対移動方向（挿抜方向）への移動を本係止位置で規制する本係止構造が設けられている。本係止構造は、係止体２６及び本係止用係止突起４６により、検知部材４０の離脱方向側への移動を規制するとともに、検知部材操作部４４及びロック用壁部２５ａにより、検知部材４０の挿入方向側への移動を規制する。 Next, the regulation of the movement of the detection member 40 with respect to the housing 20 in the relative movement direction at the present locking position will be described. As shown in FIG. 6, the detection member 40 and the housing 20 are provided with a main locking structure that regulates the movement of the detection member 40 with respect to the housing 20 in the relative movement direction (insertion / removal direction) at the main locking position. Has been done. In the locking structure, the locking body 26 and the locking projection 46 regulate the movement of the detection member 40 toward the detachment direction, and the detection member operating portion 44 and the locking wall portion 25a detect the detection member 40. The movement of the member 40 in the insertion direction side is restricted.

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造について説明する。検知部材４０は、図６に示すように、仮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、基体４１が解除操作部３２ｂから離れていくので、この基体４１の撓みが徐々に解消されていく。ここで、検知部材４０が本係止位置まで移動し終えたときには、本係止用係止突起４６が係止体２６よりも嵌合方向側に位置しており、その係止体２６と本係止用係止突起４６とが挿抜方向で互いに対向状態にある。ここでは、それぞれの係止体２６で本係止用係止突起４６の離脱方向側への移動を規制する。その係止体２６と本係止用係止突起４６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。係止体２６と本係止用係止突起４６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。 A structure for restricting the movement of the detection member 40 in the detachment direction side at the main locking position will be described. As shown in FIG. 6, in the detection member 40, the base 41 is separated from the release operation unit 32b between the time when the temporary lock state is released and the time when the detection member 40 moves to the main lock position. The bending of the is gradually eliminated. Here, when the detection member 40 finishes moving to the main locking position, the main locking projection 46 is located on the fitting direction side of the locking body 26, and the locking body 26 and the main The locking projections 46 for locking are opposed to each other in the insertion / removal direction. Here, each locking body 26 restricts the movement of the locking projection 46 for locking toward the disengagement direction. The locking body 26 and the locking projection 46 for locking restrict the movement of the detection member 40 with respect to the lock arm 31 (housing 20) toward the detachment direction at the locking position. At that time, the locking body 26 and the locking projection 46 for locking may be brought into contact with each other in the insertion / extraction direction, or may be spaced apart in the insertion / extraction direction.

検知部材４０の挿入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は、図６に示すように、仮係止位置から本係止位置まで相対移動することによって、検知部材操作部４４がハウジング２０のロック用壁部２５ａに近づいていく。検知部材操作部４４とロック用壁部２５ａとの間においては、その本係止位置での間隔を詰めることによって、検知部材操作部４４の嵌合方向側への動きをロック用壁部２５ａの端部で係止する。その検知部材操作部４４とロック用壁部２５ａの端部とを利用して、本係止位置での検知部材４０の嵌合方向側への移動を規制する。 A structure for restricting the movement of the detection member 40 in the insertion direction side at the main locking position will be described. As shown in FIG. 6, the detection member 40 moves relative to the temporary locking position to the main locking position, so that the detection member operating portion 44 approaches the locking wall portion 25a of the housing 20. By narrowing the distance between the detection member operation unit 44 and the lock wall portion 25a at the main locking position, the movement of the detection member operation unit 44 toward the mating direction is caused by the lock wall portion 25a. Lock at the end. The detection member operating portion 44 and the end portion of the locking wall portion 25a are used to regulate the movement of the detection member 40 toward the mating direction at the main locking position.

検知部材４０における、本係止位置から解除位置への相対移動について説明する。図６に示すように、完全嵌合状態において、検知部材４０が本係止位置の状態で、作業者が解除操作面４４ａを指で離脱方向に引くことにより検知部材４０を離脱方向に移動させることで、その進行と共に仮係止解除部４５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が仮係止解除部４５に対して上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、基体４１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８に示すように、仮係止解除部４５が解除操作部３２ｂを乗り越えることができる位置まで、基体４１が撓む。仮係止解除部４５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、本係止位置から解除位置へとハウジング２０に対して相対移動する。 The relative movement of the detection member 40 from the main locking position to the unlocking position will be described. As shown in FIG. 6, in the fully fitted state, with the detection member 40 in the main locked position, the operator pulls the release operation surface 44a in the release direction with a finger to move the detection member 40 in the release direction. As a result, the temporary locking release unit 45 comes into contact with the release operation unit 32b as the process progresses. Then, as the release progresses, the release operation unit 32b exerts an upward force on the temporary lock release unit 45. At that time, in the detection member 40, the base 41 begins to bend with the root on the detachment direction side as a fulcrum. In the detection member 40, the release proceeds further, and as shown in FIG. 8, the base 41 bends to a position where the temporary lock release unit 45 can get over the release operation unit 32b. By moving the temporary locking release unit 45 beyond the release operation unit 32b to the release direction side, the detection member 40 moves relative to the housing 20 from the main locking position to the release 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１１および図１２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４４ａ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が下げられハウジング２０の本体部２１に当接する。そして当接後、解除操作面４４ａ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４４が離脱方向かつ下方向に移動する。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係止部３１ｂが上方向へと撓むため、挿抜方向で係止部３１ｂと被係止部３２ａとが向かい合わないようになる。このため、解除操作面４４ａ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、嵌合解除状態とすることができる。なお、検知部材操作部４４は、嵌合解除状態において、支持部３１ｄを挟んで本体部２１に対向するとともに係止部３１ｂより離脱方向側に位置する。 The release of the completely fitted state of the connector 1 and the mating connector C will be described. As shown in FIGS. 11 and 12, the support portion 31d of the lock arm 31 is lowered and the housing 20 is lowered by the operator continuing to pull the release operation surface 44a in the disengagement direction while the detection member 40 is in the main locking position. Abuts on the main body 21 of the. Then, after the contact, by further pulling the release operation surface 44a, the release lever portion 31c of the lock arm 31 rotates around the fulcrum which is the contact point between the support portion 31d and the main body portion 21 due to the lever action, so that the detection member is operated. The portion 44 moves in the detaching direction and the downward direction. As a result, the locking portion 31b connected to one end of the release lever portion 31c on the fitting direction side bends upward, so that the locking portion 31b and the locked portion 32a do not face each other in the insertion / removal direction. Become. Therefore, by continuing to pull the release operation surface 44a, the complete mating state of the connector 1 and the mating connector C can be released, and the mating release state can be obtained. In the disengaged state, the detection member operating unit 44 faces the main body 21 with the support portion 31d interposed therebetween and is located on the side of the locking portion 31b in the detaching direction.

以上、本実施形態におけるコネクタ１によれば、検知部材４０の本係止位置から係止解除位置までの移動と、両ハウジング２０，Ｃｈの係合解除とを、作業員が検知部材操作部４４に対して外力を加えることで行う操作により、連続して行うことができる。つまり、１つの検知部材４０により、２つの操作を行うことができる。したがって、従来のコネクタのように検知部材操作部４４を操作した後に、指を離してロックアーム操作部に持ちかえて両ハウジング２０，Ｃｈ係合解除の操作をする必要がない。つまり、１つの部材である検知部材４０で、検知部材４０を本係止位置から係止解除位置まで移動させる操作と両ハウジング２０，Ｃｈの係合解除の操作とを行うことができるので、両ハウジング２０，Ｃｈを係合解除するまでの作業性を向上させることができ、コネクタ同士の離脱を容易に行うことができる。また、従来のコネクタのようにロックアーム操作部を設ける必要がなくなるため、ハウジング２０におけるロックアーム操作部の面積を確保する必要がなくなり、小型化が実現可能となる。 As described above, according to the connector 1 in the present embodiment, the worker can move the detection member 40 from the main locking position to the unlocking position and disengage the housings 20 and Ch by the operator of the detection member operating unit 44. It can be performed continuously by the operation performed by applying an external force to the housing. That is, one detection member 40 can perform two operations. Therefore, it is not necessary to release the finger and switch to the lock arm operation unit after operating the detection member operation unit 44 as in the conventional connector to disengage both housings 20 and Ch. That is, since the detection member 40, which is one member, can perform the operation of moving the detection member 40 from the main locking position to the unlocking position and the operation of disengaging the housings 20 and Ch, both of them. The workability until the housings 20 and Ch are disengaged can be improved, and the connectors can be easily disengaged from each other. Further, unlike the conventional connector, it is not necessary to provide the lock arm operating portion, so that it is not necessary to secure the area of the lock arm operating portion in the housing 20, and the miniaturization can be realized.

また、本実施形態におけるコネクタ１では、従来のロックアーム操作部に相当する解除レバー部３１ｃの連結部３１ｉの強度が不要となるので、連結部３１ｉの上下方向における長さを短く、すなわち連結部３１ｉの厚みを薄くすることができる。従って、コネクタ１の軽量化、小型化、低コスト化を図ることができる Further, in the connector 1 of the present embodiment, the strength of the connecting portion 31i of the release lever portion 31c corresponding to the conventional lock arm operating portion is not required, so that the length of the connecting portion 31i in the vertical direction is shortened, that is, the connecting portion The thickness of 31i can be reduced. Therefore, the weight, size, and cost of the connector 1 can be reduced.

また、嵌合方向側に位置し、離脱方向と向かい合う解除操作面４４ａを設けることで、作業者が解除操作面４４ａを指で離脱方向に引くことで検知部材４０を離脱方向に移動させることができるので、解除時での検知部材４０の操作性をさらに向上させることができる。また、作業者が解除操作面４４ａを離脱方向に引き続けることにより、検知部材４０を本係止位置から係止解除位置まで移動させる操作を行い、さらに両ハウジング２０，Ｃｈの係合解除の操作を行うまでの一連の動作を一度の操作で行うことできるため、従来の検知部材４０を操作する方向とロックアーム３１を操作する方向が異なるコネクタ１と比較して、検知部材４０を離脱方向に引くだけで本係止位置から係止解除位置まで移動させた状態（係止解除状態）と両ハウジング２０，Ｃｈの係合解除とができるため、コネクタ同士の離脱を容易に行うことができる。 Further, by providing the release operation surface 44a located on the mating direction side and facing the release direction, the operator can move the detection member 40 in the release direction by pulling the release operation surface 44a in the release direction with a finger. Therefore, the operability of the detection member 40 at the time of release can be further improved. Further, the operator continuously pulls the release operation surface 44a in the disengagement direction to move the detection member 40 from the main locking position to the unlocking position, and further, the disengagement operation of both housings 20 and Ch. Since a series of operations up to the above can be performed by one operation, the detection member 40 is moved in the detaching direction as compared with the connector 1 in which the direction in which the conventional detection member 40 is operated and the direction in which the lock arm 31 is operated are different. Since the state of moving from the main locking position to the unlocking position (unlocking state) and the engagement of both housings 20 and Ch can be disengaged by simply pulling, the connectors can be easily disengaged from each other.

また、ハウジング２０の成形において、支持部３１ｄと本体部２１を固定させないため、金型を離脱方向に抜くための隙間を形成することで金型の強度を確保することができる。 Further, since the support portion 31d and the main body portion 21 are not fixed in the molding of the housing 20, the strength of the mold can be ensured by forming a gap for pulling out the mold in the detaching direction.

また、支持部３１ｄは、配列方向から見た場合に、基部３１ａの離脱方向側の一端と重なる位置に形成されるため、基部３１ａの長さと係止部３１ｂの回動半径がほぼ等しいので、基部の長さと係止部の回動半径が異なる場合と比較して、ロックアーム３１の耐久性を向上させることができる。 Further, since the support portion 31d is formed at a position overlapping one end of the base portion 31a on the detachment direction side when viewed from the arrangement direction, the length of the base portion 31a and the turning radius of the locking portion 31b are substantially equal. The durability of the lock arm 31 can be improved as compared with the case where the length of the base portion and the turning radius of the locking portion are different.

なお、本実施形態においては、作業者が解除操作面４４ａを指で離脱方向に引くことで検知部材４０を離脱方向に移動させるが、これに限定されるものではなく、解除操作面４４ａを指で押してもよい。 In the present embodiment, the operator pulls the release operation surface 44a in the detachment direction with a finger to move the detection member 40 in the detachment direction, but the present invention is not limited to this, and the release operation surface 44a is referred to by the finger. You may press with.

また、上記実施形態においては、解除操作面４４ａは、離脱方向と向かい合うよう形成されているが、これに限定されるものではなく、下方向や、下方向に進むにつれて離脱方向に向かい合うよう形成されていてもよい。 Further, in the above embodiment, the release operation surface 44a is formed so as to face the detachment direction, but is not limited to this, and is formed so as to face the detachment direction as it goes downward or downward. You may be.

また、上記実施形態においては、検知部材４０がハウジング２０に対して着脱することが可能であり、かつ、解除レバー部３１ｃにロックアーム操作部が形成されていてもよい。これにより、検知部材４０がなくともロックアーム操作部を操作することで両ハウジング２０，Ｃｈの係合解除が可能となる。 Further, in the above embodiment, the detection member 40 may be attached to and detached from the housing 20, and the release lever portion 31c may be formed with a lock arm operation portion. As a result, the engagement between the housings 20 and Ch can be disengaged by operating the lock arm operating portion without the detection member 40.

また、上記実施形態においては、ハウジング２０単体での状態において、支持部３１ｄと本体部２１との間に隙間が形成されているが、これに限定されるものではなく、支持部３１ｄは本体部２１に当接する形状でもよい。 Further, in the above embodiment, a gap is formed between the support portion 31d and the main body portion 21 in the state of the housing 20 alone, but the present invention is not limited to this, and the support portion 31d is the main body portion. The shape may be in contact with 21.

また、上記実施形態においては、支持部３１ｄは、配列方向から見た場合に、基部３１ａの離脱方向側の一端と重なる位置となるように形成されているが、これに限定されるものではなく、基部３１ａの離脱方向側の一端と異なる位置に形成されていてもよい。 Further, in the above embodiment, the support portion 31d is formed so as to overlap with one end of the base portion 31a on the detachment direction side when viewed from the arrangement direction, but the present invention is not limited to this. , The base portion 31a may be formed at a position different from one end on the detaching direction side.

また、上記実施形態においては、例えば、ハウジング２０の操作空間部２４ａの離脱方向側に検知部材４０の後端と向かい合う当接面を設け、当接面及び検知部材４０の後端をそれぞれスプリングの両端に保持させることで、完全嵌合状態において、仮係止状態から本係止位置への検知部材４０の移動を弾性力で移動させる構造でもよい。 Further, in the above embodiment, for example, a contact surface facing the rear end of the detection member 40 is provided on the detaching direction side of the operation space portion 24a of the housing 20, and the contact surface and the rear end of the detection member 40 are respectively springs. By holding the detection member 40 at both ends, the detection member 40 may be moved by an elastic force from the temporarily locked state to the main locked position in the completely fitted state.

また、上記実施形態においては、検知部材４０が本係止位置のときに、作業者が解除操作面４４ａを離脱方向に引き続けることにより、嵌合解除の操作を行うが、これに限定されるものではなく、解除操作面４４ａを離脱方向以外の方向に引くことで嵌合解除の操作を行ってもよい。 Further, in the above embodiment, when the detection member 40 is in the main locking position, the operator continuously pulls the release operation surface 44a in the release direction to perform the fitting release operation, but the operation is limited to this. Instead, the release operation surface 44a may be pulled in a direction other than the detachment direction to perform the release operation.
