前記窓は、前記複数の端子金具において電線に対する接続部分の縁部と対面する位置に配置されている。前記端子金具収容室に挿入された前記端子金具が、正規の挿入状態になると、前記端子金具の前記縁部が、前記窓の挿入方向側の辺に近い位置に配置される。これにより、正規の挿入状態と判断される。 In the semi-insertion detection connector disclosed in Patent Document 1, in the housing, a plurality of terminal fitting accommodating chambers are arranged in a row side by side in the width direction orthogonal to the insertion direction of the terminal fitting. Corresponding terminal fittings are inserted into each terminal fitting storage chamber. A rectangular window extending in the width direction of the housing is formed on the bottom wall of the housing.
The window is arranged at a position facing the edge of the connection portion with respect to the electric wire in the plurality of terminal fittings. When the terminal fitting inserted into the terminal fitting accommodating chamber is in the normal insertion state, the edge portion of the terminal fitting is arranged at a position close to the side of the window on the insertion direction side. As a result, it is determined that the insertion state is normal.

一方、前記端子金具の前記縁部が、前記窓の前記挿入方向側の前記辺から離れた位置に配置される場合には、半挿入状態と判断される。 On the other hand, when the edge portion of the terminal fitting is arranged at a position away from the side of the window on the insertion direction side, it is determined to be in the semi-inserted state.

各対の第１側枠５７は、対応する上枠５３の左右方向の端部と第１中間枠５５とを連結している。一対の第２側枠５８は、第１中間枠５５の左右方向の端部と第２中間枠５６の左右方向の端部と下枠５４の左右方向の端部とを連結している。 The pair of upper frame 53, lower frame 54, first intermediate frame 55, and second intermediate frame 56 are horizontal frames. A first intermediate frame 55 is arranged above the second intermediate frame 56 between the upper frame 53 and the lower frame 54. The two pairs of the first side frame 57, the pair of the second side frames 58, and the plurality of partition frames 59 are vertical frames.
The first side frame 57 of each pair connects the left-right end portion of the corresponding upper frame 53 and the first intermediate frame 55. The pair of second side frames 58 connect the left-right end portion of the first intermediate frame 55, the left-right end portion of the second intermediate frame 56, and the left-right end portion of the lower frame 54.

横枠である各上枠と第１中間枠５５との間で、左右方向に隣接する上段の端子挿入孔５２が、縦枠である仕切り枠５９によって仕切られている。横枠である第１中間枠５５と第２中間枠５６との間で、左右方向に隣接する中段の端子挿入孔５２が、縦枠である仕切り枠５９によって仕切られている。横枠である第２中間枠５６と下枠５４との間で、左右方向に隣接する下段の端子挿入孔５２が、縦枠である仕切り枠５９によって仕切られている。上段、中断、下段の端子挿入孔５２は、左右方向に位置をずらして配置されている。 Between each upper frame which is a horizontal frame and the first intermediate frame 55, terminal insertion holes 52 in the upper stage adjacent to each other in the left-right direction are partitioned by a partition frame 59 which is a vertical frame. Between the first intermediate frame 55 and the second intermediate frame 56, which are horizontal frames, the terminal insertion holes 52 in the middle stage adjacent to each other in the left-right direction are partitioned by the partition frame 59, which is a vertical frame. A lower terminal insertion hole 52 adjacent to each other in the left-right direction is partitioned between the second intermediate frame 56, which is a horizontal frame, and the lower frame 54, by a partition frame 59, which is a vertical frame. The upper, interrupted, and lower terminal insertion holes 52 are arranged so as to be displaced in the left-right direction.

一対の弾性アーム５１は、下枠５４の一対の端部５４ａから、一対の第２側枠５８と平行に上方に延びる片持ちアームである。一対の弾性アーム５１は、先端部５１ａにおいて内向きに突出する係止突起５１ｂを有している。図示していないが、係止突起５１ｂが端子収容部８の係止部に係止することにより、リテーナ５は、仮係止位置と本係止位置とに位置保持される。 The pair of elastic arms 51 are cantilever arms extending upward in parallel with the pair of second side frames 58 from the pair of end portions 54a of the lower frame 54. The pair of elastic arms 51 have a locking projection 51b that projects inward at the tip portion 51a. Although not shown, the retainer 5 is held at the temporary locking position and the main locking position by locking the locking projection 51b to the locking portion of the terminal accommodating portion 8.

リテーナ５は、リテーナ挿入部８９に下方から挿入されて、リテーナ５の端子挿入孔５２に対して雌端子２を挿通可能な仮係止位置（図９を参照）と、前記仮係止位置よりも上方の位置であって雌端子２を抜け止めする本係止位置（図３を参照）とに変位可能である。
リテーナ５が仮係止位置にある状態で、各雌端子２をリテーナ５の対応する端子挿入孔５２に挿通させつつ、対応する端子収容室８０に対して挿入した後、リテーナ５を本係止位置側へ上昇変位させる。 The retainer 5 is inserted into the retainer insertion portion 89 from below, and the female terminal 2 can be inserted into the terminal insertion hole 52 of the retainer 5 from a temporary locking position (see FIG. 9) and the temporary locking position.

With the retainer 5 in the temporary locking position, each female terminal 2 is inserted into the corresponding terminal insertion hole 52 of the retainer 5, inserted into the corresponding terminal accommodating chamber 80, and then the retainer 5 is finally locked. It is displaced upward to the position side.

図３に示すように、各雌端子２が、挿入方向Ｋ１に関して正規位置に挿入される場合、リテーナ５を本係止位置に上昇させることができる。本係止位置にあるリテーナ５の第１中間枠５５と第２中間枠５６と下枠５４とが、それぞれの上側の端子収容室８０内に進入し、対応する雌端子２のリテーナ係止部２５と係止される。これにより、リテーナ５は、各雌端子２の抜け止め機能を果たす。 As shown in FIG. 3, when each female terminal 2 is inserted into the normal position with respect to the insertion direction K1, the retainer 5 can be raised to the main locking position. The first intermediate frame 55, the second intermediate frame 56, and the lower frame 54 of the retainer 5 at the main locking position enter the respective upper terminal accommodating chambers 80, and the retainer locking portions of the corresponding female terminals 2 enter. Locked with 25. As a result, the retainer 5 fulfills the function of preventing the female terminals 2 from coming off.

一方、少なくとも１つの雌端子２が、半挿入状態にある場合、リテーナ５の第１中間枠５５、第２中間枠５６及び下枠５４の何れかが、半挿入状態の雌端子２の端子本体２０の外側（下側）の底壁部２２ａと当接する。このため、リテーナ５を、本係止位置まで上昇させることができない。これにより、何れかの雌端子が半挿入状態にあることを検出することができる。 On the other hand, when at least one female terminal 2 is in the semi-inserted state, any one of the first intermediate frame 55, the second intermediate frame 56 and the lower frame 54 of the retainer 5 is the terminal body of the female terminal 2 in the semi-inserted state. It comes into contact with the bottom wall portion 22a on the outer side (lower side) of 20. Therefore, the retainer 5 cannot be raised to the main locking position. Thereby, it is possible to detect that any of the female terminals is in the semi-inserted state.

本実施形態では、図１２に示すように、前方からの視認により、コネクタハウジング３の端子収容部８の前壁部８４の外壁面８４ａに開口する検知開口９５の開口縁部９５ａに対して、雌端子２の半挿入検知突起２８の前端部２８ａが、面一（所定の位置）にある場合には、正規挿入状態と検知される。一方、図１３に示すように、面一にない場合には、半挿入状態と検知される。検知開口９５が形成される前壁部８４の外壁面８４ａは、相手側コネクタに対する連結時に、相手側コネクタハウジングによって覆われるため、防水性に優れる。 In the present embodiment, as shown in FIG. 12, with respect to the opening edge portion 95a of the detection opening 95 that opens to the outer wall surface 84a of the front wall portion 84 of the terminal accommodating portion 8 of the connector housing 3 by visual recognition from the front. When the front end portion 28a of the half-insertion detection protrusion 28 of the female terminal 2 is flush with each other (predetermined position), it is detected as a normal insertion state. On the other hand, as shown in FIG. 13, when it is not flush with each other, it is detected as a semi-inserted state. Since the outer wall surface 84a of the front wall portion 84 on which the detection opening 95 is formed is covered by the mating side connector housing when connected to the mating side connector, it is excellent in waterproofness.

また、図１０Ａに示すように、雌端子２の正規挿入状態で、雌端子２の端子本体２０の前端部２０ａが、コネクタハウジング３の前壁部８４の内壁面８４ｂの位置決め部９３によって位置決めされる。このため、雌端子２の端子本体２０の前端部２０ａから突出する半挿入検知突起２８の前端部２８ａと、コネクタハウジング３の端子収容部８の前壁部８４の外壁面８４ａの検知開口９５の開口縁部９５ａとの位置関係の精度が高い。これにより、正確な検知が行える。 Further, as shown in FIG. 10A, in the normally inserted state of the female terminal 2, the front end portion 20a of the terminal body 20 of the female terminal 2 is positioned by the positioning portion 93 of the inner wall surface 84b of the front wall portion 84 of the connector housing 3. To. Therefore, the detection opening 95 of the front end portion 28a of the semi-insertion detection protrusion 28 protruding from the front end portion 20a of the terminal body 20 of the female terminal 2 and the outer wall surface 84a of the front wall portion 84 of the terminal accommodating portion 8 of the connector housing 3 The accuracy of the positional relationship with the opening edge portion 95a is high. As a result, accurate detection can be performed.

また、前方（図２において紙面の手前側）からの視認により半挿入を検知する。このため、例えば３段の列の中央の列の雄端子挿入孔９２に連通する端子収容室８０に収容される雌端子２の半挿入を検知することが可能である。

本実施形態では、半挿入検知突起２９が上下方向に延在する第１基準中心線Ｃ１に対して非対称な形状を有している。このため、図１８Ａに示すように、雌端子２Ｐが上下に正規の向きで端子収容室８０に後方から挿入される場合は、雌端子２Ｐが挿入方向Ｋ１の正規位置に挿入される状態で、半挿入検知突起２９が、半挿入検知突起挿入孔９４に挿入される。半挿入検知突起２９の前端部２９ａが、検知開口９５の開口縁部９５ａと面一になる。 As shown in FIG. 17, when the female terminal 2P is viewed from the front, the semi-insertion detection protrusion 29 passes through the central position between the pair of side wall portions 23 and is orthogonal to the top wall portion 21 and the bottom wall portion 22. It is formed in an asymmetrical shape with respect to the reference center line C1.
In the present embodiment, the semi-insertion detection protrusion 29 has a shape asymmetrical with respect to the first reference center line C1 extending in the vertical direction. Therefore, as shown in FIG. 18A, when the female terminal 2P is inserted into the terminal accommodating chamber 80 in the normal orientation up and down from the rear, the female terminal 2P is inserted at the normal position in the insertion direction K1. The half-insertion detection protrusion 29 is inserted into the half-insertion detection protrusion insertion hole 94. The front end portion 29a of the semi-insertion detection protrusion 29 is flush with the opening edge portion 95a of the detection opening 95.

一方、図１８Ｂに示すように、雌端子２Ｐが上下逆向きで、端子収容室８０に後方から挿入される場合は、半挿入検知突起２９の前端部２９ａが、前壁部８４の内壁面８４ｂの位置決め部９３と当接するため、雌端子２Ｐを挿入方向Ｋ１の正規位置まで挿入できない半挿入状態となる。このため、半挿入検知突起２９を用いて、雌端子２Ｐが上下逆向きに挿入される逆挿入の発生を防止することができる。
（第３実施形態）
図１９は、本発明の第３実施形態における雌端子２Ｑの斜め上方からの斜視図であり、図２０は、雌端子２Ｑの斜め下方からの斜視図である。 On the other hand, as shown in FIG. 18B, when the female terminal 2P is turned upside down and inserted into the terminal accommodating chamber 80 from the rear, the front end portion 29a of the semi-insertion detection protrusion 29 is the inner wall surface 84b of the front wall portion 84. Since it comes into contact with the positioning portion 93 of the above, the female terminal 2P cannot be inserted to the normal position in the insertion direction K1 and is in a semi-inserted state. Therefore, the half-insertion detection protrusion 29 can be used to prevent the occurrence of reverse insertion in which the female terminal 2P is inserted upside down.
