端子金具として特許文献１に記載のものが知られている。このものは、相手の端子金具と接続可能な本体部と、この本体部より後方に連設されて電線の端末にかしめ付けられるバレル部とを備えている。端子金具はハウジングの後面に開口する端子差込口を通してハウジング内に挿入可能となっている。
実開昭６４−３８７７７号公報 The terminal metal fitting described in Patent Document 1 is known. This has a main body portion connectable to a mating terminal fitting, and a barrel portion that is connected to the rear of the main body portion and is caulked to the end of the electric wire. The terminal fitting can be inserted into the housing through a terminal insertion opening opened on the rear surface of the housing.
Japanese Utility Model Publication No. 64-38777

ところで、本体部にスタビライザ等の検知突部を設け、この検知突部がハウジングに設けられた案内溝に嵌まり込むか否かで端子金具の誤挿入の有無を判断することがある。これは、端子金具が正規姿勢をとっていれば、検知突部と案内溝とが合致して端子金具の挿入動作を許容し、端子金具が反転姿勢をとっていれば、検知突部が端子差込口の口縁に突き当たって端子金具の挿入動作を規制するというものである。なお、検知突部を本体部に設ける理由は、端子差込口にバレル部が挿入されるよりも前の早い段階で端子金具が誤挿入状態であることがわかるようにして、作業の円滑性を確保するためである。   By the way, a detection protrusion such as a stabilizer is provided on the main body, and whether or not the terminal fitting is erroneously inserted may be determined based on whether or not the detection protrusion fits into a guide groove provided in the housing. This is because if the terminal fitting is in a normal posture, the detection protrusion and the guide groove are matched to allow the insertion of the terminal fitting, and if the terminal fitting is in the inverted posture, the detection protrusion is the terminal. The insertion of the terminal fitting is restricted by abutting against the edge of the insertion slot. The reason why the detection protrusion is provided in the main body is that the terminal fitting is in the wrong insertion state at an early stage before the barrel portion is inserted into the terminal insertion port, and the smoothness of the work is achieved. This is to ensure

上記の場合には、案内溝が端子差込口の口縁に開口して外向きに延出する形態をなし、本体部が端子差込口に挿入された状態では、少なくとも検知突部の先端が案内溝に進入可能な位置に達するように検知突部の突出寸法が設定されている。一方、端子差込口の開口径は本体部とバレル部を挿通可能な大きさに設定されるので、通常、検知突部の先端位置はバレル部の背丈を越えることとなり、側方から見ると端子金具全体の中で検知突部が一段突き出るようになっている。
しかし、例えば、バレル部が本体部よりも一回り大きい端子金具の場合に、検知突部の先端位置をバレル部の背丈を越える位置に設定するとなると、検知突部の突出量が際立って大きくなり、端子金具の大型化を招くという事情がある。 In the above case, the guide groove opens at the edge of the terminal insertion port and extends outward, and at least the tip of the detection projection in the state where the main body is inserted into the terminal insertion port The projecting dimension of the detection projecting portion is set so as to reach a position where it can enter the guide groove. On the other hand, since the opening diameter of the terminal insertion port is set to a size that allows the body part and the barrel part to be inserted, the tip position of the detection protrusion usually exceeds the height of the barrel part. The detection protrusion protrudes one step in the entire terminal fitting.
However, for example, in the case of a terminal fitting whose barrel is slightly larger than the main body, if the tip of the detection protrusion is set to a position that exceeds the height of the barrel, the amount of protrusion of the detection protrusion will become significantly larger. There is a circumstance that the size of the terminal fitting is increased.

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、その目的とするところは、端子金具の大型化を回避して、端子金具の誤挿入の有無を検知可能なコネクタを提供することにある。   The present invention has been completed based on the above circumstances, and its object is to provide a connector capable of detecting the presence or absence of erroneous insertion of a terminal fitting while avoiding an increase in the size of the terminal fitting. There is to do.

上記の目的を達成するための手段として、請求項１の発明は、端子金具には、相手の端子金具と接続可能とされてその外壁に検知突部を突出させた本体部が設けられているとともに、この本体部より後方に、電線の端末にかしめ付けられたバレル部が連設され、さらに、後面に前記端子金具をその本体部から差し込み可能な端子差込口が開口する端子挿入部を備えたコネクタであって、前記端子挿入部の後面における前記端子差込口の口縁には、同端子差込口の中心を挟んだ両側位置に、誘導部と干渉部とが設けられ、前記端子金具が正規姿勢をとっている場合には、前記本体部が前記誘導部に摺動しつつ前記干渉部側へ変位することにより、前記検知突部が前記誘導部の内側空間を臨む位置に誘導されて、この位置からの前記端子金具の差し込み操作が許容される一方、前記端子金具が反転姿勢をとっている場合には、前記本体部が前記誘導部に摺動しつつ前記干渉部側へ変位することにより、前記検知突部が前記干渉部と前記端子金具の差し込み方向で対峙する位置に誘導され、この位置から前記端子金具の差し込み操作を開始しても、その開始時にあるいは差し込み途中で前記検知突部が前記干渉部と干渉してそれ以上の差し込み操作が規制される構成とし、前記コネクタは、前記端子金具を収容可能なハウジングと、このハウジングの後面に水密状態に密着するシール部材と、このシール部材の後面を押さえ付けた状態で前記シール部材を間に挟んで前記ハウジングに取り付けられるリアホルダとを備え、前記端子挿入部が前記リアホルダによって構成され、前記シール部材には、前記端子差込口と連通する位置に、前記端子金具と同端子金具に接続された電線を挿通させる電線挿入孔が形成され、前記検知突部が前記干渉部と干渉したときには前記本体部が前記電線挿入孔の内周面に非当接状態となっている構成としたところに特徴を有する。 As a means for achieving the above object, according to the first aspect of the present invention, the terminal fitting is provided with a body portion that is connectable to the mating terminal fitting and has a detection projection protruding on the outer wall thereof. In addition, a barrel portion that is caulked to the end of the electric wire is connected to the rear of the main body portion, and a terminal insertion portion that opens a terminal insertion port through which the terminal fitting can be inserted from the main body portion is provided on the rear surface. In the connector provided, the rim of the terminal insertion port on the rear surface of the terminal insertion portion is provided with a guiding portion and an interference portion at both side positions sandwiching the center of the terminal insertion port, When the terminal fitting is in a normal posture, the main body portion is displaced toward the interference portion while sliding on the guide portion, so that the detection protrusion is positioned to face the inner space of the guide portion. Induced, the difference of the terminal fitting from this position When the terminal fitting is in the inverted posture, the detection protrusion is moved to the interference portion side while sliding on the guide portion. Even if the insertion operation of the terminal fitting is started from this position, the detection projection protrudes from the interference portion and interferes with the interference portion even when the insertion operation of the terminal fitting is started from this position. The connector is configured such that further insertion operations are restricted, and the connector presses against the housing that can accommodate the terminal fitting, a sealing member that is in close contact with the rear surface of the housing in a watertight state, and the rear surface of the sealing member. A rear holder attached to the housing with the seal member interposed therebetween, wherein the terminal insertion portion is constituted by the rear holder, and the seal portion Is formed with a wire insertion hole through which the electric wire connected to the terminal fitting and the terminal fitting is inserted at a position communicating with the terminal insertion port, and when the detection protrusion interferes with the interference portion, the main body This is characterized in that the portion is in a non-contact state with the inner peripheral surface of the wire insertion hole .

＜請求項１の発明＞
端子金具は端子挿入部の後面に開口する端子差込口に差し込まれる。この場合に、端子金具が正規姿勢をとっていれば、本体部が誘導部に摺動しつつ干渉部側へ変位することにより、検知突部が誘導部の内側空間を臨む位置に誘導されるので、その位置からの端子金具の差し込み操作が許容される。一方、端子金具が反転姿勢をとっていると、同じく本体部が誘導部に摺動しつつ干渉部側へ変位するものの、検知突部は逆に干渉部と端子金具の差し込み方向で対峙する位置へ誘導されるので、その位置から端子金具の差し込み操作を開始しても、その開始時にあるいは差し込み途中で検知突部が干渉部と干渉してそれ以上の差し込み操作が規制される。つまり、検知突部の突出量を格別に増大させなくても、検知突部が誘導部によって干渉部との干渉可能な位置へ誘導されることにより、端子金具の誤挿入の有無を検知することができる。
また、端子挿入部がリアホルダによって構成されているから、ハウジングとシール部材の構造を従前から変更することなく、本発明を防水コネクタに適用することが可能となり、構造の簡素化を図れる。
さらに、シール部材には、端子金具と電線の挿通を許容する電線挿入孔が形成され、検知突部が干渉部と干渉したときには本体部が電線挿入孔の内周面に非当接状態となっているから、本体部との衝突に起因してシール部材が損傷するのを防止できる。 <Invention of Claim 1>
The terminal fitting is inserted into a terminal insertion opening opened on the rear surface of the terminal insertion portion. In this case, if the terminal fitting is in the normal posture, the detection projection is guided to a position facing the inner space of the guide portion by displacing the main body portion toward the interference portion while sliding on the guide portion. Therefore, the terminal fitting insertion operation from that position is allowed. On the other hand, if the terminal fitting is in the inverted orientation, the main body will slide to the guiding part while sliding to the guiding part, but the detection projection will be opposed to the interference part in the insertion direction of the terminal fitting. Therefore, even if the insertion operation of the terminal fitting is started from that position, the detection protrusion interferes with the interference portion at the start or during the insertion, and further insertion operation is restricted. In other words, even if the amount of protrusion of the detection protrusion is not significantly increased, the detection protrusion is guided to a position where it can interfere with the interference portion by the guide portion, thereby detecting whether or not the terminal fitting is erroneously inserted. Can do.
Further, since the terminal insertion portion is constituted by the rear holder, the present invention can be applied to the waterproof connector without changing the structure of the housing and the seal member, and the structure can be simplified.
Furthermore, the seal member is formed with an electric wire insertion hole that allows insertion of the terminal fitting and the electric wire, and when the detection protrusion interferes with the interference portion, the main body portion is not in contact with the inner peripheral surface of the electric wire insertion hole. Therefore, it is possible to prevent the seal member from being damaged due to the collision with the main body.

＜請求項２の発明＞
本体部の幅寸法が誘導部の弦長を越える位置にて本体部が端子差込口に差し込み可能とされる。この場合に、端子差込口の口縁がバレル部の断面外形と対応する形態をなし、誘導部がバレル部の巻き付き形状に沿った弧状をなしているから、端子差込口をバレル部が通過する際にバレル部の挿入動作が案内される。 <Invention of Claim 2>
The main body can be inserted into the terminal insertion slot at a position where the width dimension of the main body exceeds the chord length of the guiding portion. In this case, the rim of the terminal insertion port has a form corresponding to the cross-sectional outer shape of the barrel part, and the guide part has an arc shape along the winding shape of the barrel part. When passing, the insertion operation of the barrel portion is guided.

＜実施形態１＞
本発明の実施形態１を図１ないし図６によって説明する。本実施形態におけるコネクタ１０は、相手の雄コネクタ（図示せず）と嵌合可能な雌コネクタ１０であって防水タイプのコネクタ１０となっている。なお、以下において前後方向については、両コネクタの嵌合面側を前方として説明する。 <Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. The connector 10 in the present embodiment is a female connector 10 that can be fitted with a mating male connector (not shown), and is a waterproof connector 10. In the following, the front-rear direction will be described with the fitting surface side of both connectors as the front.

コネクタ１０は、図１に示すように、ハウジング１１、リテーナ２０、シール部材３０、リアホルダ４０を備えている。ハウジング１１は、合成樹脂材により略直方体状をなし、その内部に雌端子金具５０（本発明の端子金具に相当する）を後方から挿入して収容可能な複数のキャビティ１２を有している。キャビティ１２は、高さ方向に複数段で幅方向に複数列となって配され、その内壁に、前方へ突出する片持ち状のランス１６が撓み変形可能に形成されている。ハウジング１１の上面には、リアホルダ４０に設けられた係止脚片４１の係止爪４１Ａが引掛け状態で係止可能な係止受け部１３が段付き状に形成されている。また、ハウジング１１の上面両側部には、１対の係止脚片保護壁１４が立設されており、両係止脚片保護壁１４の間に係止脚片４１が配されることにより、係止脚片４１が異物との引掛りによって捲れ上がる事態を回避できるようになっている。   As shown in FIG. 1, the connector 10 includes a housing 11, a retainer 20, a seal member 30, and a rear holder 40. The housing 11 has a substantially rectangular parallelepiped shape made of a synthetic resin material, and has a plurality of cavities 12 in which female terminal fittings 50 (corresponding to the terminal fittings of the present invention) can be inserted and housed from behind. The cavities 12 are arranged in a plurality of rows in the height direction and in a plurality of rows in the width direction, and a cantilever lance 16 protruding forward is formed on the inner wall so as to be able to bend and deform. On the upper surface of the housing 11, a latch receiving portion 13 that can be latched in a hooked state with a latching claw 41 </ b> A of a latching leg piece 41 provided on the rear holder 40 is formed in a stepped shape. In addition, a pair of locking leg piece protective walls 14 are erected on both sides of the upper surface of the housing 11, and the locking leg pieces 41 are arranged between the both locking leg piece protective walls 14. Thus, it is possible to avoid a situation where the locking leg piece 41 is rolled up by being caught by a foreign object.

ハウジング１１の下面には、図２に示すように、リテーナ２０の差込孔１５が開口して形成されている。差込孔１５は、全キャビティ１２を貫通する深さを有し、ここに下方からサイドタイプのリテーナ２０が差し込まれる。リテーナ２０は、合成樹脂材により全体として平板状をなし、キャビティ１２と対応する位置に雌端子金具５０を挿通可能な端子通し孔２１を有するとともに、その両側上壁に、前後１対の弾性係止片２２を突設させてある。端子通し孔２１の孔壁には係止突起２３が形成され、また、弾性係止片２２はリテーナ２０の差込孔１５内に形成されたリテーナ係止部（図示せず）に弾性係止可能とされる。リテーナ２０は、仮係止位置と本係止位置との間を変位可能とされ、弾性係止片２２がリテーナ係止部に弾性係止することでリテーナ２０が両位置で抜け止め保持される。そして、リテーナ２０が仮係止位置にあるときには、係止突起２３がキャビティ１２外に退避して雌端子金具５０の挿通を許容する一方、そこから押し込まれてリテーナ２０が本係止位置に至ると、係止突起２３がキャビティ１２内に進入し、そこに正規挿入された雌端子金具５０の後端顎部５２Ｂに係止突起２３が対峙して雌端子金具５０の抜け止めをなす。   As shown in FIG. 2, an insertion hole 15 of the retainer 20 is formed in the lower surface of the housing 11 so as to open. The insertion hole 15 has a depth penetrating all the cavities 12, and a side type retainer 20 is inserted into the insertion hole 15 from below. The retainer 20 has a flat plate shape as a whole made of a synthetic resin material. The retainer 20 has a terminal through hole 21 into which the female terminal fitting 50 can be inserted at a position corresponding to the cavity 12. The stop piece 22 is projected. A locking projection 23 is formed on the hole wall of the terminal through hole 21, and the elastic locking piece 22 is elastically locked to a retainer locking portion (not shown) formed in the insertion hole 15 of the retainer 20. It is possible. The retainer 20 can be displaced between the temporary locking position and the main locking position, and the elastic locking piece 22 is elastically locked to the retainer locking portion, so that the retainer 20 is prevented from coming off at both positions. . When the retainer 20 is in the temporary locking position, the locking projection 23 is retracted out of the cavity 12 to allow the female terminal fitting 50 to be inserted, while being pushed in from there to reach the final locking position. Then, the locking projection 23 enters the cavity 12, and the locking projection 23 faces the rear end jaw portion 52B of the female terminal fitting 50 that is normally inserted therein to prevent the female terminal fitting 50 from coming off.

ハウジング１１の後面には、図１に示すように、ゴム材よりなる一括型のシール部材３０が取り付けられる。このシール部材３０は、ハウジング１１の後面全体に当接可能であって、各キャビティ１２と対応する位置毎に電線挿入孔３１を有し、各電線挿入孔３１に雌端子金具５０にかしめ付けにより接続された電線Ｗが貫通可能とされる。そして、このシール部材３０は、図２に示すように、電線挿入孔３１の内周面に形成された複数条（図示する場合は３条）のリップ３３を弾縮させつつ電線Ｗの外周に水密状に密着することで電線Ｗとの間のシールをとっている。また、シール部材３０は、各電線挿入孔３１を挟んだ上下両位置に係止脚片挿通孔３２を有し、この係止脚片挿通孔３２に係止脚片４１が貫通可能とされている。さらに、シール部材３０の外周面にも複数条（図示する場合は３条）のリップ３３が形成されており、シール部材３０に角筒状をなす相手のハウジングが外嵌されることでシール部材３０がリップ３３を弾縮させつつ相手のハウジングと水密状に密着し、もって両ハウジング間のシールをとっている。   As shown in FIG. 1, a collective seal member 30 made of a rubber material is attached to the rear surface of the housing 11. The seal member 30 can be in contact with the entire rear surface of the housing 11, has a wire insertion hole 31 for each position corresponding to each cavity 12, and is caulked to the female terminal fitting 50 in each wire insertion hole 31. The connected electric wire W can be penetrated. As shown in FIG. 2, the seal member 30 is formed on the outer periphery of the electric wire W while elastically compressing a plurality of (three in the illustrated case) lips 33 formed on the inner peripheral surface of the electric wire insertion hole 31. The seal between the wire W and the water-tight state is taken. Further, the seal member 30 has locking leg piece insertion holes 32 at both upper and lower positions sandwiching each electric wire insertion hole 31, and the locking leg pieces 41 can pass through the locking leg piece insertion holes 32. Yes. Further, a plurality of (three in the illustrated case) lips 33 are also formed on the outer peripheral surface of the sealing member 30, and the sealing member 30 is externally fitted to the sealing member 30 so that the sealing member is externally fitted. 30 closes the lip 33 in a watertight manner while elastically compressing the lip 33, thereby taking a seal between the two housings.

シール部材３０の抜け止めをなすリアホルダ４０は合成樹脂製であって、図１に示すように、その上面に、フレーム(図示せず）に対するロック部４２が形成されている。また、リアホルダ４０の片側縁からは前方へ突出する保護壁４５が形成され、この保護壁４５がシール部材３０の露出端面を覆い隠すことでシール部材３０を異物から保護している。   The rear holder 40 that prevents the sealing member 30 from coming off is made of synthetic resin, and as shown in FIG. 1, a lock portion 42 for a frame (not shown) is formed on the upper surface thereof. Further, a protective wall 45 protruding forward from one side edge of the rear holder 40 is formed, and the protective wall 45 covers the exposed end surface of the seal member 30 to protect the seal member 30 from foreign matters.

また、リアホルダ４０は、方形ブロック状のホルダ本体４６を備えている。ホルダ本体４６は、シール部材３０の電線挿入孔３１と対応する位置に、雌端子金具５０とこれに接続された電線Ｗとを電線挿入孔３１に通すための複数の端子差込口４８（後に詳しく説明する）を有し、各端子差込口４８を挟んだ上下両位置に、係止脚片４１が前方へ突出して形成されている。係止脚片４１は、後方からシール部材３０の係止脚片挿通孔３２を貫通したあとハウジング１１の上下両面に被さる長さをもって構成され、その先端部に形成された係止爪４１Ａがハウジング１１の係止受け部１３に弾性的に係止することにより、リアホルダ４０がハウジング１１との間にシール部材３０を挟んだ状態で同ハウジング１１に取り付けられる。   The rear holder 40 includes a rectangular block-shaped holder main body 46. The holder main body 46 has a plurality of terminal insertion ports 48 (later for passing the female terminal fitting 50 and the electric wires W connected thereto at positions corresponding to the electric wire insertion holes 31 of the seal member 30 through the electric wire insertion holes 31. The locking leg piece 41 is formed to protrude forward at both the upper and lower positions sandwiching each terminal insertion port 48. The locking leg piece 41 has a length that covers the upper and lower surfaces of the housing 11 after passing through the locking leg piece insertion hole 32 of the seal member 30 from the rear, and a locking claw 41A formed at the distal end of the locking leg piece 41 has a housing. The rear holder 40 is attached to the housing 11 in a state where the seal member 30 is sandwiched between the rear holder 40 and the housing 11.

リアホルダ４０に挿通される雌端子金具５０には、その前端側に図示しない相手側の雄端子金具のタブ部と接続可能とされてその外壁に検知突部５２を突出させた本体部５１が設けられるとともに、この本体部５１よりも後方に電線Ｗの端末にかしめ付けられるバレル部５３が連設されている。   The female terminal fitting 50 inserted through the rear holder 40 is provided with a main body 51 that is connectable to a tab portion of a mating male terminal fitting (not shown) on the front end side thereof and has a detection projection 52 projecting on the outer wall thereof. In addition, a barrel portion 53 that is caulked to the end of the electric wire W is provided continuously behind the main body portion 51.

本体部５１は、折り曲げ加工を施すことにより全体として角筒状をなし、その前面は雄端子金具のタブ部を挿入及び抜出可能に開口しており、内側には、雄端子金具のタブ部と電気的に弾性接触可能な弾性接触片５４が設けられている。なお、以下の雌端子金具５０の構造説明において上下方向については、雌端子金具５０が正規姿勢をとっている状態（図５に示す状態）を基準とする。
本体部５１の下面５１Ａには検知突部５２が突設されている。検知突部５２は、本体部５１の後端位置で、かつ幅方向中心から一側（本実施形態の場合は図５に示す左側）に寄った位置に設定され、その直後方には段付き状の後端顎部５２Ｂが控えている。詳しくは検知突部５２は、本体部５１の下面５１Ａを下方へ叩き出すことで側面視して略三角形状に形成され、その前面が先端側に向かって僅かに後退するテーパ状の突当面５２Ａとされている。
また、検知突部５２の下端位置は電線Ｗに対して巻き付けられた状態にあるバレル部５３の下端位置よりも上位にあって、その突出量が小さく抑えられている。検知突部５２は、後述するように、本体部５１の変位動作に伴って端子差込口４８の口縁４９（詳しくは干渉部４９Ａ）との干渉可能な位置に誘導されるようになっており、これにより検知突部５２の突出量を格別に大きくしなくてもよいようになっている。かかる検知突部５２は、その突当面５２Ａを端子差込口４８の口縁４９に突き当てることにより、雌端子金具５０の誤挿入の有無を検知する役割を担っている。 The main body 51 is formed into a rectangular tube as a whole by performing a bending process, and its front surface is open so that a tab portion of the male terminal fitting can be inserted and removed, and on the inner side, the tab portion of the male terminal fitting is provided. There is provided an elastic contact piece 54 capable of being in elastic contact with each other. In the following description of the structure of the female terminal fitting 50, the vertical direction is based on the state in which the female terminal fitting 50 is in the normal posture (the state shown in FIG. 5).
A detection projection 52 projects from the lower surface 51 </ b> A of the main body 51. The detection protrusion 52 is set at a position at the rear end position of the main body 51 and one side from the center in the width direction (left side shown in FIG. 5 in the case of the present embodiment), and a step is provided immediately thereafter. The rear end jaw 52B has a shape. Specifically, the detection protrusion 52 is formed in a substantially triangular shape when viewed from the side by knocking the lower surface 51A of the main body 51 downward, and the front surface of the detection protrusion 52A slightly recedes toward the tip side. It is said that.
Moreover, the lower end position of the detection protrusion 52 is higher than the lower end position of the barrel part 53 in a state of being wound around the electric wire W, and the protrusion amount is suppressed small. As will be described later, the detection protrusion 52 is guided to a position where it can interfere with the edge 49 (specifically, the interference portion 49A) of the terminal insertion port 48 in accordance with the displacement operation of the main body 51. Thus, the amount of protrusion of the detection protrusion 52 does not need to be significantly increased. The detection protrusion 52 plays a role of detecting whether or not the female terminal fitting 50 is erroneously inserted by abutting the contact surface 52A against the edge 49 of the terminal insertion port 48.

バレル部５３は、大電流用の回路に応じて太く形成された電線Ｗに対し幅方向両側から巻き付けられる形態をなし、このうち電線Ｗの被覆に巻き付けられる部分が、本体部５１よりも一回り大きくなっている。この電線Ｗの被覆に巻き付けられるバレル部５３の断面外形は、図６に示すように、本体部５１に連なる部分が本体部５１の上面５１Ｃと略同一平面上に沿った直線状の形態をなし、電線Ｗの被覆に巻き付けられる部分が電線Ｗの外周面に沿った曲線状（弧状）の形態をなしている。   The barrel portion 53 is configured to be wound from both sides in the width direction with respect to the electric wire W formed thick according to the circuit for large current, and the portion wound around the covering of the electric wire W is one turn than the main body portion 51. It is getting bigger. As shown in FIG. 6, the cross-sectional outer shape of the barrel portion 53 wound around the sheath of the electric wire W has a linear shape in which a portion continuous with the main body portion 51 is substantially flush with the upper surface 51 </ b> C of the main body portion 51. The part wound around the coating of the electric wire W has a curved (arc) shape along the outer peripheral surface of the electric wire W.

さて、上記した雌端子金具５０が挿通される端子差込口４８は、ホルダ本体４６の厚さ方向に貫通するとともに、ホルダ本体４６の後面に開口して形成されている。ホルダ本体４６の後面における端子差込口４８の口縁４９は、図６に示すように、雌端子金具５０のバレル部５３の断面外形にほぼ沿った略Ｄの字の形態をなし、電線Ｗの被覆に巻き付けられたバレル部５３を少し遊びをもって挿通可能な開口径を有している。そして、端子差込口４８の口縁４９には、雌端子金具５０を誘い込むためのテーパ状の面取り部４９Ｍが全周に亘って形成されており、さらに上縁の幅方向中央から一側（図４に示す右側）に寄った位置に、検知突部５２の突当面５２Ａと干渉可能な被突当面４９Ｎが形成されている。被突当面４９Ｎは、面取り部４９Ｍを分断しつつ雌端子金具５０の挿入方向と直交する鉛直方向に切り立って配されている。   Now, the terminal insertion port 48 through which the female terminal fitting 50 is inserted penetrates in the thickness direction of the holder main body 46 and is formed to open on the rear surface of the holder main body 46. As shown in FIG. 6, the edge 49 of the terminal insertion port 48 on the rear surface of the holder body 46 has a substantially D-shape substantially along the cross-sectional outline of the barrel portion 53 of the female terminal fitting 50. It has an opening diameter through which the barrel portion 53 wound around the coating can be inserted with a little play. A tapered chamfered portion 49M for guiding the female terminal fitting 50 is formed over the entire periphery at the mouth edge 49 of the terminal insertion port 48, and further, one side from the center in the width direction of the upper edge ( A contacted surface 49N that can interfere with the contact surface 52A of the detection projection 52 is formed at a position close to the right side in FIG. The abutting face 49N is arranged to stand upright in a vertical direction perpendicular to the insertion direction of the female terminal fitting 50 while dividing the chamfered portion 49M.

ホルダ本体４６の後面における端子差込口４８の口縁４９には、同端子差込口４８の中心を挟んだ上縁にて直線状をなす部分に、干渉部４９Ａが設けられ、端子差込口４８の中心を挟んだ下縁にて曲線状（弧状）をなす部分に、誘導部４９Ｂが設けられている。
ここで、雌端子金具５０が端子差込口４８の口縁４９の下側に突き当てられた場合、雌端子金具５０が正規姿勢と反転姿勢のいずれの姿勢をとっていても、誘導部４９Ｂは、雌端子金具５０の本体部５１と摺動することで本体部５１を端子差込口４８へ進入可能な位置に誘導する。
一方、雌端子金具５０が検知突部５２を上方に向けた反転姿勢をとっている場合（図２に示す上側の雌端子金具５０を参照）、干渉部４９Ａ（詳しくは被突当面４９Ｎ）は、検知突部５２の突当面５２Ａと干渉してそれ以上の雌端子金具５０の差し込み操作を規制する。もっとも、雌端子金具５０が正規姿勢をとっている場合（図２に示す下側の雌端子金具５０を参照）には、干渉部４９Ａと検知突部５２とが干渉することはない。 An interfering portion 49A is provided on the edge 49 of the terminal insertion port 48 on the rear surface of the holder main body 46 at a portion that forms a straight line at the upper edge across the center of the terminal insertion port 48. A guide portion 49B is provided in a curved portion (arc shape) at the lower edge across the center of the mouth 48.
Here, when the female terminal fitting 50 is abutted on the lower side of the edge 49 of the terminal insertion port 48, the guiding portion 49B can be used regardless of whether the female terminal fitting 50 is in the normal posture or the inverted posture. Is guided to a position where the main body 51 can enter the terminal insertion port 48 by sliding with the main body 51 of the female terminal fitting 50.
On the other hand, when the female terminal fitting 50 is in an inverted posture with the detection protrusion 52 facing upward (see the upper female terminal fitting 50 shown in FIG. 2), the interference portion 49A (specifically, the abutting face 49N) is Then, it interferes with the abutting surface 52A of the detection projection 52 and restricts further insertion operation of the female terminal fitting 50. However, when the female terminal fitting 50 is in the normal posture (see the lower female terminal fitting 50 shown in FIG. 2), the interference portion 49A and the detection projection 52 do not interfere with each other.

次に、本実施形態の組み付け手順について説明する。まずハウジング１１の後面に水密状態にシール部材３０を密着させ、シール部材３０の後面を押さえつけた状態で後方からリアホルダ４０の係止脚片４１をシール部材３０の係止脚片挿通孔３２に通しつつリアホルダ４０を取り付ける。係止脚片４１の係止爪４１Ａがハウジング１１の係止受け部１３に弾性係止することで、リアホルダ４０がシール部材３０を間に挟んでハウジング１１に取り付けられる。続いて、ハウジング１１に対して、リテーナ２０を仮係止位置に留め置き、その状態で、後方から電線Ｗに接続された雌端子金具５０を差し込む。   Next, the assembly procedure of this embodiment will be described. First, the sealing member 30 is closely attached to the rear surface of the housing 11 in a watertight state, and the locking leg piece 41 of the rear holder 40 is passed from the rear through the locking leg piece insertion hole 32 of the sealing member 30 with the rear surface of the sealing member 30 pressed. Then, the rear holder 40 is attached. The rear holder 40 is attached to the housing 11 with the seal member 30 interposed therebetween by elastically locking the locking claw 41A of the locking leg piece 41 to the locking receiving portion 13 of the housing 11. Subsequently, the retainer 20 is retained at the temporary locking position with respect to the housing 11, and in this state, the female terminal fitting 50 connected to the electric wire W is inserted from behind.

雌端子金具５０が正規姿勢をとっている場合に、本体部５１の幅寸法が誘導部４９Ｂの弦長を越えないことに起因して、本体部５１が端子差込口４８の下側の口縁４９に当接すると、本体部５１の差し込み操作は一旦規制される。しかし、本体部５１を誘導部４９Ｂに沿って図５に示す矢印方向となる干渉部４９Ａ側へ移動すると、本体部５１の全体が端子差込口４８に臨む位置に誘導され（本実施形態の場合には、本体部５１の上面５１Ｃと端子差込口４８の上端の高さ位置が一致する）、かつ、検知突部５２が誘導部４９Ｂの内側空間を臨む位置に誘導される。よって、この位置から雌端子金具５０を前方へ押し込むと、雌端子金具５０は、その本体部５１側から端子差込口４８へ円滑に進入することになる。また、本体部５１の幅寸法が誘導部４９Ｂの弦長を越えることに起因して、当初より検知突部５２が誘導部４９Ｂの内側空間を臨む位置に配されていれば、雌端子金具５０は、誘導部４９Ｂに誘導されることなく端子差込口４８へそのまますんなり進入することになる。   When the female terminal fitting 50 is in the normal posture, the width of the main body 51 does not exceed the chord length of the guiding portion 49B, so that the main body 51 is positioned below the terminal insertion port 48. When it contacts the edge 49, the insertion operation of the main body 51 is temporarily restricted. However, when the main body 51 is moved along the guiding portion 49B toward the interference portion 49A in the direction of the arrow shown in FIG. 5, the entire main body 51 is guided to a position facing the terminal insertion port 48 (in the present embodiment). In this case, the height position of the upper surface 51C of the main body 51 coincides with the height position of the upper end of the terminal insertion port 48), and the detection protrusion 52 is guided to a position facing the inner space of the guide portion 49B. Therefore, when the female terminal fitting 50 is pushed forward from this position, the female terminal fitting 50 smoothly enters the terminal insertion port 48 from the main body 51 side. In addition, if the width of the main body 51 exceeds the chord length of the guiding portion 49B, the female terminal fitting 50 may be provided if the detection protrusion 52 is disposed at a position facing the inner space of the guiding portion 49B from the beginning. Will enter the terminal insertion port 48 as it is without being guided by the guiding portion 49B.

一方、雌端子金具５０が反転姿勢をとっている場合に、上記と同様に、本体部５１の幅寸法が誘導部４９Ｂの弦長を越えないことに起因して、本体部５１が端子差込口４８の下側の口縁４９に当接すると、本体部５１の差し込み操作は一旦規制される。その後、本体部５１を誘導部４９Ｂに沿って干渉部４９Ａ側へ移動すると、本体部５１の全体が端子差込口４８に臨む位置に誘導されるものの、検知突部５２が干渉部４９Ａの被突当面４９Ｎと前後方向で同軸に対向する位置に誘導される。よって、この位置から雌端子金具５０を前方へ押し込むと、本体部５１の大部が端子差込口４８に進入するが、検知突部５２が干渉部４９Ａの被突当面４９Ｎと突き当たり、その突き当たりに起因して雌端子金具５０のそれ以上の差し込み操作が規制されることになる。なお、本体部５１の大部が端子差込口４８に進入しても、本体部５１は、図３に示すように、シール部材３０の電線挿入孔３１の内周面に当接するに至らない。   On the other hand, when the female terminal fitting 50 is in the inverted posture, the main body 51 is inserted into the terminal due to the fact that the width of the main body 51 does not exceed the chord length of the guiding portion 49B, as described above. When it comes into contact with the lower edge 49 of the mouth 48, the insertion operation of the main body 51 is temporarily restricted. Thereafter, when the main body 51 is moved along the guiding portion 49B toward the interference portion 49A, the entire main body 51 is guided to a position facing the terminal insertion port 48, but the detection protrusion 52 is covered by the interference portion 49A. It is guided to a position facing the abutting surface 49N coaxially in the front-rear direction. Therefore, when the female terminal fitting 50 is pushed forward from this position, most of the main body 51 enters the terminal insertion port 48, but the detection projection 52 abuts against the abutting surface 49N of the interference portion 49A, and the abutment. Due to this, further insertion operation of the female terminal fitting 50 is restricted. Even if most of the main body 51 enters the terminal insertion port 48, the main body 51 does not come into contact with the inner peripheral surface of the wire insertion hole 31 of the seal member 30, as shown in FIG. .

また、本体部５１の幅寸法が誘導部４９Ｂの弦長を越えることに起因して、当初より検知突部５２が干渉部４９Ａの被突当面４９Ｎと前後方向で同軸に対向している場合には、雌端子金具５０は、誘導部４９Ｂを介さずして検知突部５２が干渉部４９Ａと干渉することによりその差し込み操作が規制されることになる。 このように差し込み操作が規制された場合には、雌端子金具５０を一旦引き抜いて反転させて正規姿勢に直した後、改めて端子差込口４８に差し込むようにする。   In addition, when the width of the main body 51 exceeds the chord length of the guide portion 49B, the detection projection 52 is coaxially opposed to the abutting surface 49N of the interference portion 49A in the front-rear direction from the beginning. The insertion operation of the female terminal fitting 50 is restricted when the detection projection 52 interferes with the interference portion 49A without the guide portion 49B. When the insertion operation is restricted in this way, the female terminal fitting 50 is once pulled out and inverted to restore the normal posture, and then inserted into the terminal insertion port 48 again.

こうして本体部５１が端子差込口４８を通過した後、バレル部５３が端子差込口４８に摺動可能に挿入案内される。さらに、雌端子金具５０をシール部材３０の電線挿入孔３１からハウジング１１のキャビティ１２へと進入させ、キャビティ１２の内壁に形成されたランス１６にて１次係止させる。その後、図２に示すように、リテーナ２０を深く差し込んで本係止位置に至らしめ、リテーナ２０の係止突起２３によって雌端子金具５０を２次係止し、雌端子金具５０の確実な抜け止めをなす。   After the main body 51 passes through the terminal insertion port 48 in this way, the barrel portion 53 is slidably inserted into the terminal insertion port 48 and guided. Further, the female terminal fitting 50 is advanced from the wire insertion hole 31 of the seal member 30 into the cavity 12 of the housing 11 and is primarily locked by the lance 16 formed on the inner wall of the cavity 12. Thereafter, as shown in FIG. 2, the retainer 20 is inserted deeply to reach the final locking position, and the female terminal fitting 50 is secondarily locked by the locking projection 23 of the retainer 20, so that the female terminal fitting 50 is securely pulled out. Make a stop.

以上説明したように本実施形態によれば、雌端子金具５０の本体部５１を誘導部４９Ｂによって干渉部側へ変位させ、もって検知突部５２を干渉部４９Ａの被突当面４９Ｎとの干渉可能な位置に誘導するようにしたから、検知突部５２の突出量をバレル部５３の背丈を越える大きさに設定する必要がなく、雌端子金具５０の大型化を回避できる。   As described above, according to the present embodiment, the main body portion 51 of the female terminal fitting 50 is displaced toward the interference portion side by the guide portion 49B, so that the detection protrusion 52 can interfere with the abutting surface 49N of the interference portion 49A. Therefore, it is not necessary to set the protrusion amount of the detection protrusion 52 to a size exceeding the height of the barrel portion 53, and the size of the female terminal fitting 50 can be avoided.

また、バレル部５３が端子差込口４８に挿入される際に、誘導部４９Ｂとバレル部５３とが摺接し合うので、バレル部５３の挿入動作が円滑に進行する。さらに、検知突部５２が干渉部４９Ａと干渉しても、本体部５１が電線挿入孔３１の内周面に当接することがないので、本体部５１との突き当たりに起因するシール部材３０の損傷を防止できる。   Further, when the barrel portion 53 is inserted into the terminal insertion port 48, the guide portion 49B and the barrel portion 53 are in sliding contact with each other, so that the insertion operation of the barrel portion 53 proceeds smoothly. Further, even if the detection projection 52 interferes with the interference portion 49A, the main body 51 does not come into contact with the inner peripheral surface of the wire insertion hole 31, so that the seal member 30 is damaged due to the contact with the main body 51. Can be prevented.
