Description

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

例えば、自動車のエアバッグ回路に用いられるコネクタは、メンテナンス等で回路を開いたときにエアバッグが不用意に動作するのを防止するため、回路を構成する一対の端子金具を短絡端子によって短絡させることで両端子金具間に電位差が生じないようにしてある。
この場合、端子金具と短絡端子はハウジングに収容され、短絡端子の弾性接触片が端子金具に対して相手側のハウジングとの嵌合方向と交差する方向に弾性的に当接する構造となっている。そして、相手側のハウジングには両ハウジングの嵌合過程で端子金具と短絡端子との間に分け入って弾性接触片を短絡解除方向に撓ませる解除片が設けられている。この解除片は、通常、筒状のフード部の奥面から開口面側へ向けて細長く突出する形状となっている。なお、特許文献１には、こうしたコネクタの一例が開示されている。
特開２００５−１６６４９０公報 For example, in a connector used for an airbag circuit of an automobile, a pair of terminal fittings constituting the circuit are short-circuited by a short-circuit terminal in order to prevent the airbag from inadvertently operating when the circuit is opened for maintenance or the like. This prevents a potential difference from occurring between both terminal fittings.
In this case, the terminal fitting and the short-circuit terminal are accommodated in the housing, and the elastic contact piece of the short-circuit terminal is configured to elastically contact the terminal fitting in a direction crossing the fitting direction with the mating housing. . The mating housing is provided with a release piece that is inserted between the terminal fitting and the short-circuit terminal in the process of fitting the two housings to bend the elastic contact piece in the short-circuit release direction. This release piece usually has a shape that protrudes from the back surface of the cylindrical hood portion toward the opening surface side. Note that Patent Document 1 discloses an example of such a connector.

上記の場合、端子金具と短絡端子との接続位置がハウジングの内部に設定されていることから、両ハウジングの嵌合過程でその接続位置に解除片の先端部を至らす必要があり、解除片が長くなるのを余儀なくされた。
しかるにこのような構成であると、短絡解除時、解除片の根元には弾性接触片を撓ませるのに要する応力が集中することになるため、コネクタ小型化の要請によって解除片の根元径を十分に確保できない場合、最悪、解除片が破損・折損されるおそれもあった。また、単体状態にある雄ハウジングのフード部内に異物が入り込み、解除片が異物と干渉した場合にも破損・折損されるおそれがあった。そのため、このような突出形状の解除片以外の短絡解除手段が希求されていた。 In the above case, since the connection position between the terminal fitting and the short-circuit terminal is set inside the housing, it is necessary to bring the tip of the release piece to the connection position during the fitting process of both housings. Was forced to become longer.
However, with such a configuration, when the short circuit is released, the stress required to bend the elastic contact piece concentrates at the base of the release piece. In the worst case, the release piece could be damaged or broken. In addition, when a foreign substance enters the hood portion of the male housing in a single state and the release piece interferes with the foreign substance, there is a risk of damage or breakage. For this reason, short-circuit releasing means other than such protruding release pieces have been desired.

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、突出形状の解除片以外の短絡解除手段によって短絡端子による端子金具の短絡状態を解除するとともに、その短絡解除手段が破損・折損されないようにすることを目的とする。 The present invention has been completed based on the circumstances as described above, and the short-circuit releasing means other than the protruding release piece releases the short-circuit state of the terminal fitting by the short-circuited terminal, and the short-circuit releasing means is damaged. The purpose is to prevent breakage.

It is set up along. A temporary locking portion 15 for holding the front mask 50 in a release position (described later) is formed in the guide wall 14 in a recessed manner, and the front mask 50 is held in a short-circuited position (described later) above the guide wall 14. For this purpose, the main locking portion 16 is recessed along with the temporary locking portion 15, and the movement operation of the CFC mask is temporarily stopped at both positions. The front end of the cavity 11 is not provided with a front wall for stopping the terminal fitting 70 in front, and the front mask 50 is substituted for this.

ここで、端子金具７０は導電性の金属板を曲げ加工等して一体に形成され、前後両面が開口された角筒状の箱部７１と箱部７１よりも後方に電線圧着部７２とを備えて前後に細長い形状をなし、箱部７１内には撓み片７３が設けられ、電線圧着部７２には電線７４が固着されている。かかる端子金具７０は、後方からキャビティ１１内に挿入され、正規挿入位置においてランス１２によって弾性的に抜け止め係止される。箱部７１の上壁にはランス１２が進入可能なランス孔７５が開口され、このランス孔７５の前端開口縁にランス１２が後方から係止可能とされる。 Here, the terminal fitting 70 is integrally formed by bending a conductive metal plate or the like, and a rectangular tubular box portion 71 having both front and rear surfaces opened and a wire crimping portion 72 behind the box portion 71 are provided. It has an elongated shape in the front and rear, a bending piece 73 is provided in the box portion 71, and an electric wire 74 is fixed to the electric wire crimping portion 72. The terminal fitting 70 is inserted into the cavity 11 from the rear, and is elastically retained and locked by the lance 12 at the normal insertion position. A lance hole 75 into which the lance 12 can enter is opened on the upper wall of the box portion 71, and the lance 12 can be locked to the front end opening edge of the lance hole 75 from the rear.

雌ハウジング１０の上面の幅方向略中央部にはその前端から後方へ向けて延出されるロックアーム１７が一体に形成されている。ロックアーム１７は上下方向に弾性撓み可能とされ、両ハウジング１０，３０が正規嵌合されたときに、相手側の雄ハウジング３０（本発明の「相手側のハウジング」に相当する）に設けられたロック受け部３１を弾性係止し、これによって両ハウジング１０，３０を離脱規制状態（嵌合状態）に保持する。ロックアーム１７の上面には、ロック突起１８が突出して形成されており、このロック突起１８がロック受け部３１に対して両ハウジング１０，３０の離脱方向で当接可能とされる。ロックアーム１７の根元部１７Ａの周囲は全周に亘って切り欠かれており、この根元部１７Ａの下面はフロントマスク５０の上端と当接可能なストッパ面１７Ｂとされ、ここに解除位置から短絡位置に至ったフロントマスク５０が当て止めされる。 A lock arm 17 that extends rearward from the front end of the female housing 10 is integrally formed at a substantially central portion in the width direction of the upper surface of the female housing 10. The lock arm 17 can be elastically bent in the vertical direction, and is provided in the mating male housing 30 (corresponding to the “mating housing” of the present invention) when both the housings 10 and 30 are properly fitted. The lock receiving portion 31 is elastically locked, thereby holding the housings 10 and 30 in the disengagement restricted state (fitted state). A lock protrusion 18 protrudes from the upper surface of the lock arm 17, and the lock protrusion 18 can be brought into contact with the lock receiving portion 31 in the direction in which both the housings 10 and 30 are detached. The periphery of the base portion 17A of the lock arm 17 is cut out over the entire circumference, and the lower surface of the base portion 17A is a stopper surface 17B that can come into contact with the upper end of the front mask 50, and this is short-circuited from the release position. The front mask 50 reaching the position is stopped.

また、雌ハウジング１０には、その上下方向略中央部であって短絡対象となるキャビティ１１の下方（ランス１２と反対側）に、短絡端子８０を収容するための短絡端子収容部１９が形成されている。短絡端子収容部１９は、雌ハウジング１０の前面に開口されるとともにキャビティ１１の前部に連通する作動空間１９Ａと、雌ハウジング１０の後面に開口されるとともに略水平なスリット状をなす固定空間１９Ｂとを有する。作動空間１９Ａの後面の略下半部（固定空間１９Ｂを挟んで下部側の領域）は前下がりの傾斜面１９Ｃとされる一方、作動空間１９Ａの後面の略上半部（固定空間１９Ｂを挟んで上部側の領域）は前上がりの傾斜面１９Ｄとされ、両傾斜面１９Ｃ，１９Ｄによって短絡端子８０の作動領域が規定されている。 Further, the female housing 10 is formed with a short-circuit terminal accommodating portion 19 for accommodating the short-circuit terminal 80 at a substantially central portion in the vertical direction below the cavity 11 to be short-circuited (on the side opposite to the lance 12). ing. The short-circuit terminal accommodating portion 19 is opened at the front surface of the female housing 10 and communicates with the front portion of the cavity 11, and the fixed space 19 B is opened at the rear surface of the female housing 10 and has a substantially horizontal slit shape. And have. A substantially lower half of the rear surface of the working space 19A (a region on the lower side across the fixed space 19B) is a forwardly inclined surface 19C, while a substantially upper half of the rear surface of the working space 19A (the fixed space 19B is sandwiched). The upper region is an upwardly inclined surface 19D, and the operation region of the short-circuiting terminal 80 is defined by both the inclined surfaces 19C and 19D.

そして、雌ハウジング１０には、固定空間１９Ｂを縦断しつつ雌ハウジング１０の下面に開口されるリテーナ収容部２０が形成されている。ここに組み付けられるリテーナ７６は前後に貫通する貫通孔７７を有してブロック状をなし、仮係止位置と本係止位置との間を移動可能とされ、仮係止位置では、貫通孔７７がキャビティ１１と整合することで端子金具７０のキャビティ１１への挿抜動作を許容し、本係止位置では、キャビティ１１内に正規挿入された端子金具７０の箱部７１の後端を抜け止め係止する。また、このリテーナ７６には、解除位置と短絡位置のいずれの位置においても、固定空間１９Ｂと対応することで、短絡端子８０との干渉を回避可能な逃がし孔７８が前後に貫通して形成されている。 The female housing 10 is formed with a retainer receiving portion 20 that is opened on the lower surface of the female housing 10 while being vertically cut through the fixed space 19B. The retainer 76 assembled here has a through-hole 77 penetrating in the front-rear direction to form a block shape, and is movable between the temporary locking position and the main locking position. Allows the terminal fitting 70 to be inserted into and removed from the cavity 11 by aligning with the cavity 11, and the rear end of the box portion 71 of the terminal fitting 70 that is normally inserted into the cavity 11 is prevented from coming off at the final locking position. Stop. The retainer 76 is formed with a relief hole 78 penetrating in the front-rear direction so as to avoid interference with the short-circuit terminal 80 by corresponding to the fixed space 19B at any position of the release position and the short-circuit position. ing.

フロントマスク５０は合成樹脂製であって、雌ハウジング１０の前面に沿って移動可能であり、雌ハウジング１０の前面に露出して組み付けられる。このフロントマスク５０は、全体として雌ハウジング１０の前面に沿った平板状をなし、雌ハウジング１０の両ガイド壁１４間に嵌合されつつ短絡位置とそれよりも下方の解除位置との間を上下方向に移動可能とされる。具体的にはフロントマスク５０は、短絡位置では短絡端子８０による端子金具７０の短絡状態を維持し、短絡位置から解除位置への移動動作によって短絡端子８０による端子金具７０の短絡状態を解除し、さらに解除位置では端子金具７０の短絡解除状態を維持する。 The front mask 50 is made of synthetic resin, is movable along the front surface of the female housing 10, and is exposed and assembled to the front surface of the female housing 10. The front mask 50 has a flat plate shape along the front surface of the female housing 10 as a whole, and is fitted between the guide walls 14 of the female housing 10 so as to move up and down between a short-circuit position and a release position below the short-circuit position. It is possible to move in the direction. Specifically, the front mask 50 maintains the short-circuit state of the terminal fitting 70 by the short-circuit terminal 80 at the short-circuit position, and releases the short-circuit state of the terminal fitting 70 by the short-circuit terminal 80 by the movement operation from the short-circuit position to the release position. Further, the short-circuit release state of the terminal fitting 70 is maintained at the release position.

フロントマスク５０の左右両側縁には、左右一対の仮係止受け部５１が突出して形成されるとともに、それより下方に左右一対の本係止受け部５２が仮係止受け部５１と並んで突出して形成されており、解除位置において仮係止受け部５１が仮係止部１５に係止され（図１０を参照）、短絡位置において仮係止受け部５１が本係止部１６に係止されるとともに本係止受け部５２が仮係止部１５に係止されるようになっている（図９を参照）。フロントマスク５０は、雌ハウジング１０の組付空間１３に収容され、短絡位置ではその下面が雌ハウジング１０の下面とほぼ面一で略水平に連なる一方、解除位置ではその下面が雌ハウジング１０の下面よりも下方に位置して、その下端部が組付空間１３より下方に突出して配置される。 A pair of left and right temporary locking receiving portions 51 protrude from the left and right side edges of the front mask 50, and a pair of left and right permanent locking receiving portions 52 are aligned with the temporary locking receiving portions 51 below the front mask 50. The temporary locking receiving portion 51 is locked to the temporary locking portion 15 at the release position (see FIG. 10), and the temporary locking receiving portion 51 is connected to the main locking portion 16 at the short-circuit position. In addition to being stopped, the main lock receiving portion 52 is locked to the temporary lock portion 15 (see FIG. 9). The front mask 50 is accommodated in the assembly space 13 of the female housing 10, and its lower surface is substantially flush with the lower surface of the female housing 10 at the short-circuited position and is substantially horizontal, while its lower surface is the lower surface of the female housing 10 at the release position. The lower end portion of the assembly space 13 protrudes downward from the assembly space 13.

フロントマスク５０の上端縁の幅方向略中央部はここを挟んだ左右両側部よりも一段凹んだ凹部５３となっており（図８を参照）、この凹部５３がロックアーム１７の根元部１７Ａに下から嵌合され、短絡位置では凹部５３の底面がストッパ面１７Ｂに突き当て状態で当接される。また、フロンマスクの上端縁のうち、凹部５３を挟んだ左右両側部は、短絡位置と解除位置のいずれの位置においても上方に向けて露出状態で配置され、相手側の雄ハウジング３０に設けられた移動手段によって押圧される解除用被押圧面５４となっている。この解除用被押圧面５４はフロントマスク５０の上端縁において前下がりのテーパ状をなしている。一方、フロントマスク５０の下端縁は短絡位置と解除位置のいずれの位置においても下方に向けて露出状態で配置され、相手側の雄ハウジング３０に設けられた戻り方向の移動手段によって上記とは逆向きに押圧される短絡用被押圧面５５となっている。なお、仮係止受け部５１と仮係止部１５との係止状態、仮係止受け部５１と本係止部１６との係止状態、及び本係止受け部５２と仮係止部１５との係止状態は、短絡用被押圧面５５及び解除用被押圧面５４からの押圧力を受けて解除される。 A substantially central portion in the width direction of the upper end edge of the front mask 50 is a recessed portion 53 that is recessed by one step from the left and right side portions sandwiching the front mask 50 (see FIG. 8), and the recessed portion 53 is formed on the root portion 17A of the lock arm 17. It is fitted from below and the bottom surface of the recess 53 is brought into contact with the stopper surface 17B at the short-circuit position. In addition, left and right side portions of the upper end edge of the front mask sandwiching the recess 53 are disposed in an exposed state upward in both the short-circuit position and the release position, and are provided in the mating male housing 30. It becomes the pressed surface 54 for release pressed by the moving means. The release pressing surface 54 has a taper shape with a front lowering at the upper edge of the front mask 50. On the other hand, the lower end edge of the front mask 50 is disposed in an exposed state downward in both the short-circuit position and the release position, and is opposite to the above by the moving means in the return direction provided in the opposite male housing 30. This is a short-circuited pressed surface 55 that is pressed in the direction. It should be noted that the temporary locking receiving portion 51 and the temporary locking portion 15 are locked, the temporary locking receiving portion 51 and the main locking portion 16 are locked, and the final locking receiving portion 52 and the temporary locking portion. The latched state with 15 is released upon receiving a pressing force from the short-circuited pressed surface 55 and the releasing pressed surface 54.

そして、フロントマスク５０には、複数の端子挿通口５６と治具挿通口５７とが相互に独立した態様で前後に貫通して形成されている。端子挿通口５６は解除位置ではキャビティ１１内に収容された端子金具７０と対応する高さに位置して端子金具７０がここに臨み、短絡位置ではランス１２の型抜き空間２１と対応する高さに位置してランス１２がここに臨む。一方、治具挿通口５７は、端子挿通口５６と幅方向に位置ずれしつつその上方に対応して配置され、解除位置ではランス１２の型抜き空間２１と対応する高さに位置してランス１２がここに臨む。したがって、フロントマスク５０が解除位置にあるときには、端子挿通口５６から相手側の雄端子金具７９のタブ７９Ａが挿入されて端子金具７０と接続可能とされるとともに、治具挿通口５７から解除治具（図示せず）が挿入されてランス１２を端子金具７０から解離させる方向に撓ませることで端子金具７０の抜き取りが可能とされる。なお、端子挿通口５６の前半部の口縁はタブ７９Ａの誘い込み面５６Ａとして前方へ向けてラッパ状に開口されている。 The front mask 50 is formed with a plurality of terminal insertion openings 56 and jig insertion openings 57 penetrating in the front-rear direction in an independent manner. The terminal insertion port 56 is positioned at a height corresponding to the terminal metal fitting 70 accommodated in the cavity 11 at the release position, and the terminal metal fitting 70 faces here, and at the short-circuiting position, the height corresponding to the die cutting space 21 of the lance 12. The lance 12 faces here. On the other hand, the jig insertion port 57 is disposed so as to be displaced from the terminal insertion port 56 in the width direction and corresponding to the upper portion thereof, and is located at a height corresponding to the die cutting space 21 of the lance 12 at the release position. Twelve faces here. Therefore, when the front mask 50 is in the release position, the tab 79A of the mating male terminal fitting 79 is inserted from the terminal insertion opening 56 so that it can be connected to the terminal fitting 70, and the release insertion from the jig insertion opening 57 is possible. By inserting a tool (not shown) and bending the lance 12 in a direction to disengage from the terminal fitting 70, the terminal fitting 70 can be removed. The front edge of the terminal insertion port 56 is opened in a trumpet shape as a leading surface 56A for the tab 79A.

また、フロントマスク５０の後面（雌ハウジング１０の前面と対向する面）には雌ハウジング１０において幅方向で隣接するキャビティ１１間を仕切る仕切り壁と連続するリブ５８が上下に延出されるとともに幅方向に複数並んで形成されている。各リブ５８間の空間は端子金具７０の前端部が後方から進入する進入空間５９とされ、キャビティ１１内に挿入された端子金具７０の前端部は進入空間５９に嵌合されるとともにその左右両側をリブ５８によって拘束されることで幅方向に遊動規制される。 In addition, ribs 58 that continue to the partition walls that partition the cavities 11 adjacent to each other in the width direction in the female housing 10 extend vertically on the rear surface of the front mask 50 (the surface that faces the front surface of the female housing 10). Are formed side by side. The space between the ribs 58 is an entry space 59 in which the front end portion of the terminal fitting 70 enters from behind, and the front end portion of the terminal fitting 70 inserted into the cavity 11 is fitted into the entry space 59 and the left and right sides thereof. Is restricted by the ribs 58, and the free movement is restricted in the width direction.

そして、フロントマスク５０の後面には、後方へ突出する左右一対の解除本体６０が一体に形成されている。解除本体６０は、それぞれ同形同大であって、フロントマスク５０の高さ方向略中央部において左右両側に間隔をあけつつそれぞれ同じ高さに位置している（図７を参照）。具体的には解除本体６０はその断面形状が略方形をなし、かつその先端（突出端）の周縁部には先細り状のテーパ面６０Ａが形成されている。また、解除本体６０は、短絡位置ではキャビティ１１内に挿入された端子金具７０の箱部７１を下から支承してその短絡状態を保持することが可能となっている。さらに、解除本体６０は、解除位置へとフロントマスク５０が下降した状態では、短絡端子８０の弾性接触片８１Ｂ（後述する）を下方（短絡解除方向）へ変位させることが可能となっている。つまり、解除本体６０はフロントマスク５０と一体となって、短絡位置と解除位置との間（端子金具７０の前端部を支承する位置と弾性接触片８１Ｂを撓ませる位置との間）で上下方向（端子金具７０に対する弾性接触片８１Ａ，８１Ｂの当接・離間方向と略平行な方向であって、両ハウジング１０，３０の嵌合・離脱方向と交差（略直交）する方向）に変位するようになっている。かかる解除本体６０の移動経路は、短絡端子収容部１９の作動空間１９Ａ内となっている。なお、解除本体６０の突出寸法は、雄ハウジング３０の前面が組付空間１３によって後方へ控えた位置にあることに起因し、短く抑えられている。 A pair of left and right release bodies 60 projecting rearward are integrally formed on the rear surface of the front mask 50. The release main bodies 60 have the same shape and the same size, and are positioned at the same height while being spaced apart on both the left and right sides at a substantially central portion in the height direction of the front mask 50 (see FIG. 7). Specifically, the release main body 60 has a substantially square cross-sectional shape, and a tapered surface 60A that is tapered is formed at the peripheral edge of the tip (projecting end). Moreover, the cancellation | release main body 60 can support the box part 71 of the terminal metal fitting 70 inserted in the cavity 11 from the bottom in the short circuit position, and can hold | maintain the short circuit state. Furthermore, the release body 60 can displace an elastic contact piece 81B (described later) of the short-circuit terminal 80 downward (short-circuit release direction) in a state where the front mask 50 is lowered to the release position. In other words, the release main body 60 is integrated with the front mask 50 and vertically between the short circuit position and the release position (between the position where the front end of the terminal fitting 70 is supported and the position where the elastic contact piece 81B is bent). (A direction parallel to the contact / separation direction of the elastic contact pieces 81A and 81B with respect to the terminal fitting 70 and intersecting (substantially orthogonal to) the fitting / removal direction of the housings 10 and 30) It has become. The movement path of the release main body 60 is in the working space 19 A of the short-circuit terminal accommodating portion 19. Note that the protruding dimension of the release main body 60 is kept short due to the fact that the front surface of the male housing 30 is in a position where it is kept backward by the assembly space 13.

短絡端子８０は導電性の金属板を曲げ加工等して一体に形成されており、方形平板状をなして略水平に配置される端子本体８２と、端子本体８２の前端縁から前方へ向けて片持ち状の延出される左右一対の弾性接触片８１Ａ，８１Ｂとからなる。端子本体８２の後端寄りの位置には、前上がりの傾斜をもって片持ち状に延出される前進規制片８３が弾性撓み可能に形成されている。前進規制片８３が固定空間１９Ｂの壁面を引掛け状態で弾性係止することで、短絡端子８０の前進が規制される。また、短絡端子８０には後退規制片（図示せず）が形成されており、この後退規制片が固定空間１９Ｂの壁面を引掛け状態で弾性係止することで、短絡端子８０の後退が規制される。 The short-circuit terminal 80 is integrally formed by bending a conductive metal plate or the like. The terminal body 82 is formed in a rectangular flat plate shape and is disposed substantially horizontally, and the front end edge of the terminal body 82 is directed forward. It consists of a pair of left and right elastic contact pieces 81A, 81B that are cantilevered. At a position near the rear end of the terminal body 82, a forward restricting piece 83 extending in a cantilever manner with a forwardly rising slope is formed so as to be elastically deformable. The advance restriction piece 83 elastically locks the wall surface of the fixed space 19 B in a hooked state, whereby the advance of the short-circuit terminal 80 is restricted. The short-circuit terminal 80 is formed with a retreat restricting piece (not shown), and the retreat restricting piece elastically locks the wall surface of the fixed space 19B in a hooked state, thereby restricting the retreat of the short-circuit terminal 80. Is done.

そして、両弾性接触片８１Ａ，８１Ｂのうち一方の弾性接触片８１Ａ（正面から見て左側の弾性接触片８１Ａ）は、端子本体８２から面一状（ほぼ水平）に延出される延出部８２Ａと、延出部８２Ａの前端からほぼ直角に近い角度で上向きに立ち上がるとともにその立上がり部８３Ａの上端から斜め下前方へ傾斜部８４Ａを延出させた態様の接触部８５Ａとからなる（図３を参照）。接触部８５Ａの頂上部（上端部）は、端子金具７０の箱部７１の下面に当接する接点部８６Ａとなっている。かかる弾性接触片８１Ａは、延出部８２Ａの後端（端子本体８２への支持位置）を支点として上下方向に弾性撓み可能となっている。 One elastic contact piece 81A (the elastic contact piece 81A on the left side when viewed from the front) of the elastic contact pieces 81A and 81B is extended from the terminal body 82 in a flush manner (substantially horizontal). And a contact portion 85A that rises upward from the front end of the extending portion 82A at an angle close to a right angle and extends the inclined portion 84A obliquely downward and forward from the upper end of the rising portion 83A (see FIG. 3). reference). The top (upper end) of the contact portion 85 A serves as a contact portion 86 A that comes into contact with the lower surface of the box portion 71 of the terminal fitting 70. The elastic contact piece 81A can be elastically bent in the vertical direction with the rear end (supporting position to the terminal body 82) of the extending portion 82A as a fulcrum.

これに対し、他方の弾性接触片８１Ｂ（正面から見て右側の弾性接触片８１Ｂ）は、端子本体８２から面一状（ほぼ水平）に延出される延出部８２Ｂと、延出部８２Ｂの前端からほぼ直角に近い角度で上向きに立ち上がるとともにその立上がり部８３Ｂの上端から斜め下前方へ傾斜部８４Ｂを延出させた態様の接触部８５Ｂと、傾斜部８４Ｂの前端から前方へ突出する受け部８７Ｂとからなる。接触部８５Ｂの頂上部（上端部）は、端子金具７０の箱部７１の下面に当接する接点部８６Ｂとなっている。かかる弾性接触片８１Ｂは、延出部８２Ｂの後端（端子本体８２への支持位置）を支点として上下方向に弾性撓み可能となっている。 On the other hand, the other elastic contact piece 81B (the elastic contact piece 81B on the right side when viewed from the front) includes an extension portion 82B extending from the terminal body 82 in a flush manner (substantially horizontal), and an extension portion 82B. A contact portion 85B that rises upward at an angle close to a right angle from the front end and extends the inclined portion 84B obliquely downward and forward from the upper end of the rising portion 83B, and a receiving portion that protrudes forward from the front end of the inclined portion 84B 87B. The top (upper end) of the contact portion 85 B serves as a contact portion 86 B that comes into contact with the lower surface of the box portion 71 of the terminal fitting 70. The elastic contact piece 81B can be elastically bent in the vertical direction with the rear end (supporting position to the terminal body 82) of the extending portion 82B as a fulcrum.

両弾性接触片８１Ａ，８１Ｂが弾性撓みしていない自由状態においては、両接触部８５Ａ，８５Ｂの立上がり部８３Ａ，８３Ｂは前後方向において互いに同じ位置にあり、その立ち上がり角度も互いに同じ角度で、かつ、接点部８６Ａ，８６Ｂも互いに同じ高さにある。ただし、両傾斜部８４Ａ，８４Ｂの前端の高さが互いに同じ高さ（端子本体８２及び延出部８２Ａ，８２Ｂよりも上位）であるが、他方の傾斜部８４Ｂの前端の位置は、一方の傾斜部８４Ａの前端よりも後方に位置している。換言すると、他方の傾斜部８４Ｂの傾斜角度は、一方の傾斜部８４Ａの傾斜角度よりもきつい（大きい）角度となっている。そして、他方の弾性接触片８１Ｂにのみ形成されている受け部８７Ｂはほぼ水平であって、その受け部８７Ｂの前端は、前後方向において一方の傾斜部８４Ａの前端と同じ位置にある。つまり、両弾性接触片８１Ａ，８１Ｂの前端は、前後方向ついて互いに同じ位置にあり、かつ互いに同じ高さに位置している。 In a free state where the elastic contact pieces 81A and 81B are not elastically bent, the rising portions 83A and 83B of the both contact portions 85A and 85B are at the same position in the front-rear direction, and their rising angles are the same as each other, and The contact portions 86A and 86B are also at the same height. However, the heights of the front ends of both inclined portions 84A and 84B are the same height (higher than the terminal body 82 and the extending portions 82A and 82B), but the position of the front end of the other inclined portion 84B is It is located behind the front end of the inclined portion 84A. In other words, the inclination angle of the other inclined portion 84B is a tighter (larger) angle than the inclination angle of the one inclined portion 84A. The receiving portion 87B formed only on the other elastic contact piece 81B is substantially horizontal, and the front end of the receiving portion 87B is at the same position as the front end of the one inclined portion 84A in the front-rear direction. That is, the front ends of both elastic contact pieces 81A and 81B are at the same position in the front-rear direction and at the same height.

雌ハウジング１０の嵌合相手である雄ハウジング３０は合成樹脂製であって、奥壁を構成する端子装着部３２と、端子装着部３２の周縁から前方へ向けて筒状、詳細には角筒状に突出するフード部３３とからなる。端子装着部３２には雄端子金具７９が装着され、雄端子金具７９のタブ７９Ａがフード部３３内に突出して配置されている。雄端子金具７９は全体として略Ｌの字に屈曲され、その下端が端子装着部３２の後方においてプリント回路基板９０の導電路に接続される。かかるフード部３３には雌ハウジング１０が内嵌されるようになっており、その嵌合動作に伴い、タブ７９Ａがフロントマスク５０の端子挿通口５６を通ってキャビティ１１内に進入し、端子金具７０の箱部７１内の撓み片７３に接触して両端子金具７０，７９の接続がとられる。なお、フード部３３の奥面には検知端子を保護する保護壁３４が突成されているが、従来において短絡端子８０に対応して突成されていた短絡解除手段としての解除片は設けられていない。また、フード部３３の上壁内面の前端幅方向略中央部には、ロックアーム１７と弾性係止可能なロック受け部３１が下向きに突出して形成されている。 The male housing 30 which is a mating partner of the female housing 10 is made of synthetic resin, and has a terminal mounting portion 32 constituting a back wall and a cylindrical shape from the periphery of the terminal mounting portion 32 to the front. And a hood portion 33 protruding in a shape. A male terminal fitting 79 is attached to the terminal attachment portion 32, and a tab 79 A of the male terminal fitting 79 is disposed so as to protrude into the hood portion 33. The male terminal fitting 79 is bent into a substantially L shape as a whole, and its lower end is connected to the conductive path of the printed circuit board 90 behind the terminal mounting portion 32. The female housing 10 is fitted into the hood portion 33, and in accordance with the fitting operation, the tab 79A enters the cavity 11 through the terminal insertion port 56 of the front mask 50, and the terminal fitting. The two terminal fittings 70 and 79 are connected in contact with the bending piece 73 in the box portion 71 of 70. A protective wall 34 that protects the detection terminal is projected on the inner surface of the hood portion 33, but a release piece as a short-circuit releasing means that is conventionally projected corresponding to the short-circuit terminal 80 is provided. Not. Further, a lock receiving portion 31 that can be elastically locked to the lock arm 17 is formed to protrude downward at a substantially central portion in the front end width direction on the inner surface of the upper wall of the hood portion 33.

さて、フード部３３の内面には、雌ハウジング１０との嵌合動作に伴ってフロントマスク５０を短絡位置から解除位置に移動させる移動手段として第一カム面３５Ａと、雌ハウジング１０との離脱動作に伴ってフロントマスク５０を解除位置から短絡位置に移動させる戻り方向の移動手段としての第二カム面３５Ｂとが設けられている。第一カム面３５Ａはフード部３３の内面の上壁側に位置し、第二カム面３５Ｂはフード部３３の内面の下壁側に位置している。そして、第一カム面３５Ａは、フード部３３の内面においてロック受け部３１を挟んだ左右両側に対をなして配置され、第二カム面３５Ｂは、フード部３３の内面において第一カム面３５Ａと対向する左右両側に対をなして配置される（図６を参照）。 Now, on the inner surface of the hood 33, the first cam surface 35A as a moving means for moving the front mask 50 from the short-circuited position to the release position in accordance with the fitting operation with the female housing 10, and the detaching operation with the female housing 10. Accordingly, a second cam surface 35B is provided as a return direction moving means for moving the front mask 50 from the release position to the short-circuit position. The first cam surface 35 A is located on the upper wall side of the inner surface of the hood portion 33, and the second cam surface 35 B is located on the lower wall side of the inner surface of the hood portion 33. The first cam surface 35 A is arranged in pairs on the left and right sides of the inner surface of the hood portion 33 with the lock receiving portion 31 interposed therebetween, and the second cam surface 35 B is disposed on the inner surface of the hood portion 33. Are arranged in pairs on the left and right sides facing each other (see FIG. 6).

具体的にフード部３３の内面の上壁側は、このフード部３３の開口端から後方（奥面側）へ向けてほぼ水平に延出される第一前側水平面３６Ａと、第一前側水平面３６Ａの後端を始端としてそこから後方へ向けてテーパ状の下り勾配となる第一カム面３５Ａと、第一カム面３５Ａの終端（後端）からフード部３３の奥面にかけてほぼ水平に延出される第一後側水平面３７Ａとからなる（図１を参照）。第一カム面３５Ａの始端は、前後方向についてフード部３３の深さ方向中央よりやや前方にあり、第一カム面３５Ａの終端は、前後方向についてフード部３３の深さ方向中央とほぼ対応する位置にある。なお、フード部３３の深さは雌ハウジング１０の嵌合ストローク量に対応している。そして、フード部３３の上壁の厚みは、第一前側水平面３６Ａと対応する側で薄く、第一後側水平面３７Ａと対応する側で厚くなっており、かつ、第一カム面３５Ａと対応する側では後方へ行くにしたがって次第に厚くなる形態とされる。 Specifically, the upper wall side of the inner surface of the hood portion 33 includes a first front horizontal plane 36A extending substantially horizontally from the opening end of the hood portion 33 toward the rear (back side), and a first front horizontal plane 36A. A first cam surface 35A having a taper-like downward slope from the rear end to the rear side from the rear end, and extending substantially horizontally from the end (rear end) of the first cam surface 35A to the inner surface of the hood portion 33. It consists of 37 A of 1st back side horizontal surfaces (refer FIG. 1). The start end of the first cam surface 35A is slightly ahead of the center in the depth direction of the hood portion 33 in the front-rear direction, and the end of the first cam surface 35A substantially corresponds to the center in the depth direction of the hood portion 33 in the front-rear direction. In position. The depth of the hood portion 33 corresponds to the fitting stroke amount of the female housing 10. The thickness of the upper wall of the hood 33 is thin on the side corresponding to the first front horizontal surface 36A, thick on the side corresponding to the first rear horizontal surface 37A, and corresponds to the first cam surface 35A. On the side, the thickness gradually increases toward the rear.

一方、フード部３３の内面の下壁側は、このフード部３３の開口端から後方（奥面側）へ向けてほぼ水平に延出される第二前側水平面３６Ｂと、第二前側水平面３６Ｂの後端を始端としてそこから後方へ向けてテーパ状の下り勾配となる第二カム面３５Ｂと、第二カム面３５Ｂの終端（後端）からフード部３３の奥面にかけてほぼ水平に延出される第二後側水平面３７Ｂとからなる。第二カム面３５Ｂの始端は、前後方向についてフード部３３の深さ方向中央よりやや前方にあり、第二カム面３５Ｂの終端は、前後方向についてフード部３３の深さ方向中央とほぼ対応する位置にある。つまり、第二カム面３５Ｂと第一カム面３５Ａの前後位置は略一致している。また、第二カム面３５Ｂと第一カム面３５Ａは、ほぼ同じ傾斜角度をもって傾斜しており、互いに略平行に配置されている。そして、フード部３３の下壁の厚みは、第二前側水平面３６Ｂと対応する側で厚く、第二後側水平面３７Ｂと対応する側で薄くなっており、かつ、第二カム面３５Ｂと対応する側では後方へ行くにしたがって次第に薄くなる形態とされる。 On the other hand, the lower wall side of the inner surface of the hood portion 33 is located behind the second front horizontal surface 36B extending substantially horizontally from the opening end of the hood portion 33 toward the rear (back surface side) and the second front horizontal surface 36B. A second cam surface 35B having a tapered downward slope from the end to the rear end, and a second cam surface extending substantially horizontally from the terminal end (rear end) of the second cam surface 35B to the back surface of the hood portion 33. It consists of two rear side horizontal surfaces 37B. The start end of the second cam surface 35B is slightly ahead of the center in the depth direction of the hood portion 33 in the front-rear direction, and the end of the second cam surface 35B substantially corresponds to the center in the depth direction of the hood portion 33 in the front-rear direction. In position. That is, the front and rear positions of the second cam surface 35B and the first cam surface 35A are substantially the same. Further, the second cam surface 35B and the first cam surface 35A are inclined at substantially the same inclination angle, and are arranged substantially parallel to each other. The thickness of the lower wall of the hood portion 33 is thicker on the side corresponding to the second front horizontal surface 36B, thinner on the side corresponding to the second rear horizontal surface 37B, and corresponds to the second cam surface 35B. On the side, the thickness is gradually reduced toward the rear.

第一後側水平面３７Ａと第二前側水平面３６Ｂとの高さ位置の差は雌ハウジング１０の左右両側の高さ寸法に等しく、これにより、雌ハウジング１０は、雄ハウジング３０との嵌合過程で、第一後側水平面３７Ａと第二前側水平面３６Ｂとによって上下に挟まれた状態でフード部３３の奥面側へ向けて略水平に進行する。また、第一前側水平面３６Ａと第二前側水平面３６Ｂとの高さ位置の差は、両水平面３６Ａ，３６Ｂ間に嵌入されるフロントマスク５０の左右両側の高さ寸法（解除用被押圧面５４の上端から短絡用被押圧面５５の下端までの距離）にほぼ等しい。よって、雌ハウジング１０がフード部３３内に浅く嵌入した状態では、雌ハウジング１０において短絡位置に組み付けられたフロントマスク５０の解除用被押圧面５４が第一カム面３５Ａと前後で対面して配置される。その状態で、雌ハウジング１０をフード部３３の奥面側へ移動させると、解除用被押圧面５４が第一カム面３５Ａの始端に至りそこから第一カム面３５Ａを摺動するとともに、この摺接動作によってフロントマスク５０に下方（解除位置側）への押圧力が付与され、フロントマスク５０が徐々に下降して行く。そして、解除用被押圧面５４が第一カム面３５Ａの終端に至ると、フロントマスク５０が解除位置に達して、解除本体６０によって短絡端子８０による端子金具７０同士の短絡状態が解除される。 The difference in height position between the first rear horizontal surface 37A and the second front horizontal surface 36B is equal to the height of the left and right sides of the female housing 10, so that the female housing 10 is in the process of fitting with the male housing 30. The hood portion 33 travels substantially horizontally toward the back surface side while being sandwiched between the first rear horizontal surface 37A and the second front horizontal surface 36B. Further, the difference in height position between the first front horizontal surface 36A and the second front horizontal surface 36B is the height dimension of the left and right sides of the front mask 50 fitted between the horizontal surfaces 36A and 36B (the pressed surface 54 for release). It is substantially equal to the distance from the upper end to the lower end of the shorted pressed surface 55). Therefore, in a state where the female housing 10 is shallowly fitted in the hood portion 33, the release pressed face 54 of the front mask 50 assembled at the short-circuit position in the female housing 10 is disposed so as to face the first cam surface 35 A in the front-rear direction. Is done. In this state, when the female housing 10 is moved to the back surface side of the hood portion 33, the release-target pressed surface 54 reaches the start end of the first cam surface 35A and slides on the first cam surface 35A from there. By the sliding contact operation, a downward pressing force (on the release position side) is applied to the front mask 50, and the front mask 50 gradually descends. When the release pressing surface 54 reaches the end of the first cam surface 35A, the front mask 50 reaches the release position, and the release body 60 releases the short-circuit state between the terminal fittings 70 by the short-circuit terminals 80.

フード部３３の内部空間のうち第一カム面３５Ａよりも前方領域は、解除用被押圧面５４を含むフロントマスク５０の上端部が進入する前側逃がし空間３８とされる。一方、フード部３３の内部空間のうち第二カム面３５Ｂよりも後方領域は、短絡用被押圧面５５を含むフロントマスク５０の下端部が進入する後側逃がし空間３９とされる。また、第一後側水平面３７Ａと第二後側水平面３７Ｂとの高さ位置の差は、両水平面３７Ａ，３７Ｂ間に嵌入されるフロントマスク５０の左右両側の高さ寸法（解除用被押圧面５４の上端から短絡用被押圧面５５の下端までの距離）に等しい。よって、両ハウジング１０，３０が正規嵌合された状態では、フロントマスク５０の短絡用被押圧面５５が第二カム面３５Ｂと前後で対面して配置される。その状態で、雌ハウジング１０をフード部３３の開口面側へ移動させる（両ハウジング１０，３０を離脱させる）と、短絡用被押圧面５５が第二カム面３５Ｂを摺動するとともに、この摺接動作によってフロントマスク５０に上方（短絡位置側）への押圧力が付与され、フロントマスク５０が徐々に上昇して行く。そして、短絡用被押圧面５５が第二カム面３５Ｂの始端に至ると、フロントマスク５０が短絡位置に達して、解除本体６０による短絡解除状態が解除されて、端子金具７０が再び短絡状態となる。 A region in front of the first cam surface 35 A in the internal space of the hood portion 33 is a front-side escape space 38 into which the upper end portion of the front mask 50 including the release-target pressed surface 54 enters. On the other hand, a region behind the second cam surface 35 B in the internal space of the hood portion 33 serves as a rear escape space 39 into which the lower end portion of the front mask 50 including the shorted pressed surface 55 enters. Further, the difference in height position between the first rear horizontal surface 37A and the second rear horizontal surface 37B is the height dimension on both the left and right sides of the front mask 50 inserted between the horizontal surfaces 37A and 37B (pressed surface for release). The distance from the upper end of 54 to the lower end of the shorted pressed surface 55). Therefore, in a state where both the housings 10 and 30 are properly fitted, the short-circuited pressed surface 55 of the front mask 50 is disposed to face the second cam surface 35B in the front-rear direction. In this state, when the female housing 10 is moved to the opening surface side of the hood portion 33 (both housings 10 and 30 are detached), the short-circuited pressed surface 55 slides on the second cam surface 35B, and this sliding By the contact operation, an upward pressing force (short circuit position side) is applied to the front mask 50, and the front mask 50 gradually rises. When the short-circuited pressed surface 55 reaches the start end of the second cam surface 35B, the front mask 50 reaches the short-circuit position, the short-circuit release state by the release main body 60 is released, and the terminal fitting 70 is again short-circuited. Become.

次に、本実施形態の作用を説明する。まず、雌ハウジング１０の組み付け工程について説明する。
組み付けにあたり、雌ハウジング１０のリテーナ収容部２０にリテーナ７６を差し込んで仮係止位置に保持しておく。続いて、雌ハウジング１０の短絡端子収容部１９に対して前方から短絡端子８０を挿入する。短絡端子８０の挿入過程では端子本体８２が固定空間１９Ｂに圧入状態で進入する。 Next, the operation of this embodiment will be described. First, the assembly process of the female housing 10 will be described.
In assembling, the retainer 76 is inserted into the retainer accommodating portion 20 of the female housing 10 and held at the temporary locking position. Subsequently, the short-circuit terminal 80 is inserted into the short-circuit terminal accommodating portion 19 of the female housing 10 from the front. In the insertion process of the short-circuit terminal 80, the terminal body 82 enters the fixed space 19B in a press-fit state.

次いで、雌ハウジング１０の組付空間１３に対して下方からフロントマスク５０をガイド壁１４の内面に沿わせつつ組み付ける。フロントマスク５０が短絡位置に達すると、凹部５３にロックアーム１７の根元部１７Ａが嵌合するとともに、本係止受け部５２が仮係止部１５に係止される（図９を参照）。このとき、短絡端子８０の両弾性接触片８１Ａ，８１Ｂの前端を解除本体６０の移動経路よりも後方に待避させておくことでフロントマスク５０の組み付けに伴って解除本体６０が弾性接触片８１Ａ，８１Ｂと干渉するのを回避できる。フロントマスク５０の組み付け後、待避位置にある短絡端子８０を前方の正規組付位置まで移動させる。短絡端子８０が正規組付位置に達すると、前進規制片８３及び後退規制片による係止作用によって短絡端子８０が雌ハウジング１０に対して前後に移動規制状態に固定される。この状態では、両弾性接触片８１Ａ，８１Ｂの上端部がキャビティ１１内に進入している。 Next, the front mask 50 is assembled to the assembly space 13 of the female housing 10 from below along the inner surface of the guide wall 14. When the front mask 50 reaches the short-circuit position, the base portion 17A of the lock arm 17 is fitted into the recess 53, and the main latch receiving portion 52 is latched to the temporary latch portion 15 (see FIG. 9). At this time, by releasing the front ends of both elastic contact pieces 81A and 81B of the short-circuiting terminal 80 behind the movement path of the release main body 60, the release main body 60 becomes elastic contact pieces 81A, Interference with 81B can be avoided. After the front mask 50 is assembled, the short-circuit terminal 80 in the retracted position is moved to the front regular assembly position. When the short-circuit terminal 80 reaches the normal assembly position, the short-circuit terminal 80 is fixed to the female housing 10 in the forward and backward movement restricted state by the locking action of the forward restriction piece 83 and the backward restriction piece. In this state, the upper ends of both elastic contact pieces 81 A and 81 B enter the cavity 11.

その後、後方からキャビティ１１内に端子金具７０を挿入する。挿入過程では、ランス１２が端子金具７０の箱部７１の上面に当接することで上方へ弾性撓みするとともに、弾性接触片８１Ａ，８１Ｂが作動空間１９Ａ内で下方へ弾性撓みする。そして、端子金具７０が正規挿入位置に達すると、箱部７１の前端がフロントマスク５０によって前止まりされるとともに、ランス１２の係止作用によって端子金具７０の後方への抜けが規制される。この後、仮係止位置にあるリテーナ７６を本係止位置に移動させると、端子金具７０がランス１２とリテーナ７６とで二重係止状態に抜け止めされる。 Thereafter, the terminal fitting 70 is inserted into the cavity 11 from the rear. In the insertion process, the lance 12 abuts on the upper surface of the box portion 71 of the terminal fitting 70 and is elastically bent upward, and the elastic contact pieces 81A and 81B are elastically bent downward in the working space 19A. When the terminal fitting 70 reaches the normal insertion position, the front end of the box portion 71 is stopped in front by the front mask 50 and the terminal metal 70 is prevented from coming out backward by the locking action of the lance 12. Thereafter, when the retainer 76 in the temporary locking position is moved to the final locking position, the terminal fitting 70 is prevented from coming off in a double locked state by the lance 12 and the retainer 76.

かく端子金具７０が正規挿入されると、短絡端子８０は、両弾性接触片８１Ａ，８１Ｂを下方へ撓ませつつ箱部７１に対して接点部８６Ａ，８６Ｂを弾性的に当接させ、この当接動作によって左右（幅方向）に並ぶ一対の端子金具７０を導通可能に接続（短絡）させる。このとき、弾性接触片８１Ａ，８１Ｂの端子金具７０への当接方向は端子金具７０の長さ方向（両ハウジング１０，３０の嵌合・離脱方向と略平行な方向）に対してほぼ直角な上向きの方向となる。また、箱部７１に対する弾性接触片８１Ａ，８１Ｂ（接点部８６Ａ，８６Ｂ）の当接位置は、前後方向について箱部７１に対するランス１２の係止位置とほぼ同じ位置となる。そして、弾性接触片８１Ａ，８１Ｂの弾性復元力により、箱部７１は上方（ランス１２側）へ押し上げられるため、箱部７１とランス１２との係止代を深く確保することができる。 Thus, when the terminal fitting 70 is properly inserted, the short-circuit terminal 80 elastically contacts the contact portions 86A and 86B against the box portion 71 while bending both elastic contact pieces 81A and 81B downward. By the contact operation, the pair of terminal fittings 70 arranged in the left and right (width direction) are connected (short-circuited) in a conductive manner. At this time, the contact direction of the elastic contact pieces 81A and 81B to the terminal fitting 70 is substantially perpendicular to the length direction of the terminal fitting 70 (direction substantially parallel to the fitting / removing direction of the housings 10 and 30). The direction is upward. Further, the contact positions of the elastic contact pieces 81A and 81B (contact portions 86A and 86B) with respect to the box portion 71 are substantially the same as the locking positions of the lance 12 with respect to the box portion 71 in the front-rear direction. Since the box portion 71 is pushed upward (to the lance 12 side) by the elastic restoring force of the elastic contact pieces 81A and 81B, a locking allowance between the box portion 71 and the lance 12 can be secured deeply.

また、弾性接触片８１Ａ，８１Ｂが弾性撓みしている状態では、弾性接触片８１Ａ，８１Ｂが前下がりの姿勢をとってその前端が弾性接触片８１Ａ，８１Ｂの後端部（撓みの支点）よりも下方に位置する。そして、他方の弾性接触片８１Ｂの受け部８７Ｂは、自由状態における水平姿勢から前下がりの傾斜姿勢をとる。つまり、受け部８７Ｂの前端縁から解除本体６０の下面までの直線距離は、受け部８７Ｂの後端縁から解除本体６０の下面までの直線距離よりも大きくなっている。また、フロントマスク５０が短絡位置にある状態では、解除本体６０が箱部７１の前端部の下面に当接または近接して対向し、これにより、解除本体６０が箱部７１の前端部を下から支承し得る状態となる。 Further, in a state where the elastic contact pieces 81A and 81B are elastically bent, the elastic contact pieces 81A and 81B take a front-down posture, and the front ends thereof are from the rear end portions (flexion fulcrums) of the elastic contact pieces 81A and 81B. Is also located below. Then, the receiving portion 87B of the other elastic contact piece 81B takes a tilted posture that is forwardly lowered from a horizontal posture in a free state. That is, the linear distance from the front end edge of the receiving portion 87B to the lower surface of the release body 60 is larger than the linear distance from the rear end edge of the receiving portion 87B to the lower surface of the release body 60. In the state where the front mask 50 is in the short-circuit position, the release main body 60 abuts or faces the lower surface of the front end portion of the box portion 71 so that the release main body 60 lowers the front end portion of the box portion 71. It will be in a state that can be supported from.

一方、キャビティ１１内の端子金具７０を抜き取る際には、まず本係止位置にあるリテーナ７６を仮係止位置に移動させて、リテーナ７６による抜け止め状態を解除する。続いて、フロントマスク５０の治具挿通口５７に対して前方から解除治具を差し込み、解除治具の先端でランス１２を上方（係止解除方向）に撓ませることによって端子金具７０から離間させ、ランス１２による抜け止め状態を解除する。そして、この解除治具による解除状態を保ったまま、雌ハウジング１０の後面から導出されている電線７４を摘んで方向へ引っ張り、端子金具７０をキャビティ１１から抜き取るようにする。 On the other hand, when the terminal fitting 70 in the cavity 11 is extracted, first, the retainer 76 in the final locking position is moved to the temporary locking position, and the retaining state by the retainer 76 is released. Subsequently, the release jig is inserted into the jig insertion port 57 of the front mask 50 from the front, and the lance 12 is bent upward (in the unlocking direction) at the tip of the release jig to be separated from the terminal fitting 70. The release prevention state by the lance 12 is released. Then, while keeping the release state by the release jig, the electric wire 74 led out from the rear surface of the female housing 10 is picked and pulled in the direction so that the terminal fitting 70 is removed from the cavity 11.

次に、上記によってフロントマスク５０を短絡位置に組み付けた雌ハウジング１０を相手側の雄ハウジング３０に嵌合させる工程について説明する。
まず、フード部３３の開口に雌ハウジング１０を対面させ、その状態からフード部３３内に雌ハウジング１０を嵌入して行く（図１を参照）。このときの嵌入方向は端子金具７０に対する短絡端子８０の当接・離間方向と略直角な方向となる。雌ハウジング１０の嵌入動作が進むのに伴い、フロントマスク５０の解除用被押圧面５４が第一カム面３５Ａに摺接し、その傾斜によって解除用被押圧面５４が下向きに押圧され、その押圧力によって短絡位置に保持されているフロントマスク５０が下方（解除位置側）へ押し下げられる（図２を参照）。なお、フロントマスク５０の解除用被押圧面５４が第一カム面３５Ａの始端に至るのは雌ハウジング１０がフード部３３内に略半分進入した時点である。そして、フロントマスク５０は、解除用被押圧面５４が第一カム面３５Ａの終端に至ることによって解除位置に達する（図３を参照）。 Next, a process of fitting the female housing 10 in which the front mask 50 is assembled at the short-circuiting position to the mating male housing 30 will be described.
First, the female housing 10 faces the opening of the hood portion 33, and the female housing 10 is inserted into the hood portion 33 from this state (see FIG. 1). The insertion direction at this time is a direction substantially perpendicular to the contact / separation direction of the short-circuit terminal 80 with respect to the terminal fitting 70. As the fitting operation of the female housing 10 progresses, the release pressed surface 54 of the front mask 50 comes into sliding contact with the first cam surface 35A, and the release pressed surface 54 is pressed downward by the inclination, and the pressing force As a result, the front mask 50 held at the short-circuit position is pushed downward (release position side) (see FIG. 2). Note that the release pressing surface 54 of the front mask 50 reaches the starting end of the first cam surface 35 A when the female housing 10 enters approximately half of the hood portion 33. The front mask 50 reaches the release position when the release pressed surface 54 reaches the end of the first cam surface 35A (see FIG. 3).

かくフロントマスク５０が短絡位置から解除位置へ移動するのに伴い、フロントマスク５０の解除本体６０が短絡端子８０における他方の弾性接触片８１Ｂの受け部８７Ｂに対して上から押圧し、この押圧動作によって他方の弾性接触片８１Ｂのみが下方へ移動して端子金具７０から離間する。これにより、左右に並んで対をなす端子金具７０同士は短絡端子８０による短絡状態を解除される。 Thus, as the front mask 50 moves from the short-circuit position to the release position, the release body 60 of the front mask 50 presses the receiving portion 87B of the other elastic contact piece 81B in the short-circuit terminal 80 from above, and this pressing operation. Therefore, only the other elastic contact piece 81B moves downward and is separated from the terminal fitting 70. As a result, the pair of terminal fittings 70 arranged side by side are released from the short-circuited state due to the short-circuit terminal 80.

フロントマスク５０が解除位置に至った後、さらに雌ハウジング１０の嵌入動作が進むと、雄端子金具７９のタブ７９Ａがフロントマスク５０の治具挿通口５７を通してキャビティ１１内に進入する。この間、フロントマスク５０は、解除用被押圧面５４が第一後側水平面３７Ａに摺接することによって解除位置に保たれる。雌ハウジング１０がフード部３３に正規深さで嵌入される（両ハウジング１０，３０が正規嵌合される）と、フロントマスク５０が解除位置に保たれたままフロントマスク５０の前面がフード部３３の奥面（端子装着部３２の前面）に当接し、かつ、雌ハウジング１０の下面の前端部がフード部３３の内面との間に後側逃がし空間３９を保有しつつ、タブ７９Ａと端子金具７０とが正規接続される（図４を参照）。なお、雌ハウジング１０はフード部３３内に嵌入される全工程を通じて略水平に移動し、フロントマスク５０は第一カム面３５Ａ（第二カム面３５Ｂを含む）に摺接する間を除いて略水平に移動する。 When the insertion operation of the female housing 10 further proceeds after the front mask 50 reaches the release position, the tab 79A of the male terminal fitting 79 enters the cavity 11 through the jig insertion port 57 of the front mask 50. During this time, the front mask 50 is held at the release position by the release pressing surface 54 being in sliding contact with the first rear horizontal surface 37A. When the female housing 10 is fitted into the hood part 33 at a normal depth (both housings 10 and 30 are normally fitted), the front surface of the front mask 50 is kept in the release position while the front mask 50 is kept in the release position. The tab 79A and the terminal fitting are in contact with the rear surface (the front surface of the terminal mounting portion 32) and the front end portion of the lower surface of the female housing 10 holds the rear escape space 39 between the inner surface of the hood portion 33 and 70 is normally connected (see FIG. 4). The female housing 10 moves substantially horizontally throughout the entire process of being fitted into the hood portion 33, and the front mask 50 is substantially horizontal except during the time when it is in sliding contact with the first cam surface 35A (including the second cam surface 35B). Move to.

一方、メンテナンス等により嵌合状態にある両ハウジング１０，３０を離脱させる際には、ロックアーム１７とロック受け部３１とのロック状態を解除した後、雌ハウジング１０の後端部を摘んでこの雌ハウジング１０をフード部３３から離間する方向に引っ張るようにする。すると、解除位置にあるフロントマスク５０の下端部における短絡用被押圧面５５が第二カム面３５Ｂに摺接し、その傾斜によって短絡用被押圧面５５が上向きに押圧され、その押圧力によって解除位置に保持されているフロントマスク５０が上方（短絡位置側）へ押し上げられる。フロントマスク５０は、短絡用被押圧面５５が第二カム面３５Ｂの始端に至ることによって短絡位置に達する（図２を参照）。フロントマスク５０が解除位置から短絡位置へ移動するのに伴い、フロントマスク５０の解除本体６０が受け部８７Ｂから離間して受け部８７Ｂへの押圧状態を解除し、これによって他方の弾性接触片８１Ｂが弾性復帰方向に変位して端子金具７０の箱部７１の下面に再び当接する。その後は、雌ハウジング１０をフード部３３から引き離すことにより、フロントマスク５０が短絡位置に組み付けられた雌ハウジング１０が単体として得られる。 On the other hand, when the two housings 10 and 30 in the fitted state are detached due to maintenance or the like, after the locked state of the lock arm 17 and the lock receiving portion 31 is released, the rear end portion of the female housing 10 is grasped. The female housing 10 is pulled in a direction away from the hood portion 33. Then, the short-circuited pressed surface 55 at the lower end portion of the front mask 50 in the release position is in sliding contact with the second cam surface 35B, and the short-circuited pressed surface 55 is pressed upward by the inclination, and the release position is released by the pressing force. The front mask 50 held in the position is pushed upward (short-circuit position side). The front mask 50 reaches the short-circuit position when the short-circuited pressed surface 55 reaches the start end of the second cam surface 35B (see FIG. 2). As the front mask 50 moves from the release position to the short-circuit position, the release main body 60 of the front mask 50 moves away from the receiving portion 87B to release the pressed state to the receiving portion 87B, thereby the other elastic contact piece 81B. Is displaced in the elastic return direction and again comes into contact with the lower surface of the box portion 71 of the terminal fitting 70. Thereafter, by pulling the female housing 10 away from the hood portion 33, the female housing 10 in which the front mask 50 is assembled at the short-circuit position is obtained as a single unit.

以上のようの本実施形態によれば次の効果を奏する。
両ハウジング１０，３０の嵌合動作に伴って雄ハウジング３０の第一カム面３５Ａがフロントマスク５０において露出して配された解除用被押圧面５４と当接（摺接）することにより、フロントマスク５０の全体が雌ハウジング１０の前面に沿って短絡位置から解除位置へと移動し、その移動動作によってフロントマスク５０に一体に形成された解除本体６０が短絡端子８０の弾性接触片８１Ｂを短絡解除方向に撓ませるから、端子金具７０の短絡状態を解除する短絡解除手段として従来の解除片を用いなくて済む。そして、雄ハウジング３０側の移動手段としては、雌ハウジング１０の前面に露出されたフロントマスク５０の露出部分（解除用被押圧面５４）と当接する構造であれば足りるから、フード部３３の内面における第一カム面３５Ａによって構成されることとなり、従来の解除片と違って破損・折損されるおそれはない。 According to the present embodiment as described above, the following effects are obtained.
The first cam surface 35A of the male housing 30 is brought into contact (sliding contact) with the release pressed surface 54 that is exposed and arranged in the front mask 50 as the housings 10 and 30 are fitted together. The entire mask 50 moves along the front surface of the female housing 10 from the short-circuit position to the release position, and the release body 60 integrally formed with the front mask 50 by the moving operation short-circuits the elastic contact piece 81B of the short-circuit terminal 80. Since it is bent in the releasing direction, it is not necessary to use a conventional releasing piece as a short-circuit releasing means for releasing the short-circuit state of the terminal fitting 70. As the moving means on the male housing 30 side, any structure that abuts the exposed portion of the front mask 50 exposed on the front surface of the female housing 10 (the pressed surface 54 for release) is sufficient. Unlike the conventional release piece, there is no risk of breakage or breakage.

また、フロントマスク５０は、短絡端子８０による端子金具７０の短絡状態を解除する機能に加え、ランス１２の型抜き空間２１の前方を覆いつつタブ７９Ａを位置決めした状態で端子金具７０との接続位置へ誘導するという機能を有するから、両機能を有する部材が別々に設けられるのに比べ、部品点数を少なくできる。 Further, the front mask 50 has a function of releasing the short-circuited state of the terminal fitting 70 by the short-circuiting terminal 80 and, in addition, a position where the tab 79A is positioned while covering the front of the die-cutting space 21 of the lance 12. Therefore, the number of parts can be reduced as compared with the case where members having both functions are provided separately.

さらに、戻り方向の移動手段として第二カム面３５Ｂが設けられており、両ハウジング１０，３０の離脱動作に伴って第二カム面３５Ｂがフロントマスク５０の短絡用被押圧面５５と当接（摺接）することにより、フロントマスク５０の全体が雌ハウジング１０の前面に沿って解除位置から短絡位置へ戻り方向に移動して、端子金具７０の短絡状態が回復されるから、両ハウジング１０，３０の分離後にフロントマスク５０の短絡位置への戻し作業を手操作等で別途行わずに済み、作業性が良好となる。
そして、このような第一カム面３５Ａ及び第二カム面３５Ｂによって雄ハウジング３０側の移動手段が構成されることにより、雄ハウジング３０全体の構成を簡素化できる。 Further, a second cam surface 35B is provided as a moving means in the return direction, and the second cam surface 35B comes into contact with the short-circuited pressed surface 55 of the front mask 50 (see FIG. (Sliding contact), the entire front mask 50 moves along the front surface of the female housing 10 from the release position to the short-circuit position in the return direction, and the short-circuit state of the terminal fitting 70 is recovered. After the separation of 30, the work of returning the front mask 50 to the short-circuited position does not have to be performed separately by manual operation or the like, and workability is improved.
And the structure of the whole male housing 30 can be simplified by comprising the moving means by the side of the male housing 30 by such 1st cam surface 35A and 2nd cam surface 35B.
