Further, the front end surface of the substrate K is disposed so as to be retracted to the rear side of the front end surface of the male housing 10 and is disposed at a position substantially flush with the inner peripheral surface of the case 20. The front end surface of the male housing 10 is disposed at a position that is substantially flush with the outer peripheral surface of the case 20. The substrate K is supported in a substantially horizontal posture with respect to the case 20 by support means (not shown).

続いて、雌ハウジング30について説明する。雌ハウジング30は、合成樹脂製とされており、全体が横長な略ブロック状に形成されるとともに、その内部には、複数本(計40本)の雌端子金具31が収容可能とされる。詳しくは雌ハウジング30には、電線Wの端末に接続された雌端子金具31を後方から挿入可能なキャビティ32が、相手の雄端子金具14と対応した位置にそれぞれ設けられている。雌端子金具31は、前後に開口する略箱形をなす本体部31aと、電線Wの端末に圧着接続されるバレル部31bとを前後に繋げた構成とされており、本体部31a内には、雄端子金具14のコネクタ側接続部14aと弾性接触可能な弾性接触片31cが設けられている。また各キャビティ32内には、本体部31aの後端の段部に対して係止して雌端子金具31を抜け止め保持可能な片持ち状のランス33が設けられている。   Next, the female housing 30 will be described. The female housing 30 is made of synthetic resin, and is formed in a substantially block shape as a whole, and a plurality (for a total of 40) of female terminal fittings 31 can be accommodated therein. Specifically, the female housing 30 is provided with cavities 32 into which the female terminal fittings 31 connected to the ends of the electric wires W can be inserted from the rear at positions corresponding to the male terminal fittings 14 of the counterpart. The female terminal fitting 31 has a configuration in which a main body portion 31a having a substantially box shape that opens front and rear and a barrel portion 31b that is crimped and connected to the terminal of the electric wire W are connected to each other in the front and rear. In addition, an elastic contact piece 31c capable of elastic contact with the connector side connection portion 14a of the male terminal fitting 14 is provided. Each cavity 32 is provided with a cantilevered lance 33 that can be locked to the stepped portion at the rear end of the main body 31a to prevent the female terminal fitting 31 from being detached.

雌ハウジング30の上面には、嵌合時に雄ハウジング10の被ロック部15に係止可能なロックアーム34が設けられている。ロックアーム34は、前後方向に沿って延出するとともに上下方向に沿って弾性変形可能とされており、その上面には上方へ突出するとともに雄ハウジング10の被ロック部15に対して係止可能なロック突部35が設けられている。   On the upper surface of the female housing 30, a lock arm 34 that can be locked to the locked portion 15 of the male housing 10 when fitted is provided. The lock arm 34 extends in the front-rear direction and is elastically deformable in the vertical direction. The lock arm 34 protrudes upward on the upper surface and can be locked to the locked portion 15 of the male housing 10. A lock projection 35 is provided.

さて、雌ハウジング30には、嵌合に伴って基板Kのうち雄ハウジング10が取り付けられた表面Kaとは反対側の裏面Kbに対して係止可能とされる規制部36が設けられている。詳しくは、規制部36は、雌ハウジング30のうち嵌合状態において雄ハウジング10よりも後方へ突出して配される後端部の下面から下方へ突出する突出部37と、この突出部37から前方へ延出する片持ち状の係止片38とから構成されており、全体として断面略L字型をなしている。係止片38は、基板Kとほぼ平行な略板状をなすとともに雌ハウジング30の下面と対向して配されている。係止片38の上面38aと雌ハウジング30の下面との間の距離は、フード部12の下部の厚み寸法と基板Kの厚み寸法とを足し合わせた大きさとほぼ同じか、それよりもやや大きく設定されており、さらには係止片38の長さ寸法は、ケース20の厚み寸法よりも所定長さ大きく設定されている。従って、雌ハウジング30を雄ハウジング10に嵌合すると、係止片38は、基板Kの裏側(雄ハウジング10が取り付けられた側とは反対側)に入り込むとともにその裏面Kbに対して係止片38の上面38a(基板Kとの対向面)が係止されるようになっている。一方、ケース20の開口部21は、そこに内嵌するフード部12の外形よりも下方へ拡張されており、その拡張部分21aに上記した規制部36の係止片38が挿通可能とされている。   The female housing 30 is provided with a restricting portion 36 that can be locked to the rear surface Kb of the board K opposite to the front surface Ka to which the male housing 10 is attached in accordance with the fitting. . Specifically, the restricting portion 36 includes a protruding portion 37 that protrudes downward from the lower surface of the rear end portion that is arranged to protrude rearward from the male housing 10 in the fitted state of the female housing 30, and forward from the protruding portion 37. It has a cantilevered locking piece 38 extending to the end, and has a substantially L-shaped cross section as a whole. The locking piece 38 has a substantially plate shape substantially parallel to the substrate K and is disposed to face the lower surface of the female housing 30. The distance between the upper surface 38a of the locking piece 38 and the lower surface of the female housing 30 is approximately the same as or slightly larger than the sum of the thickness of the lower portion of the hood 12 and the thickness of the substrate K. Further, the length dimension of the locking piece 38 is set larger than the thickness dimension of the case 20 by a predetermined length. Therefore, when the female housing 30 is fitted to the male housing 10, the locking piece 38 enters the back side of the substrate K (the side opposite to the side on which the male housing 10 is attached) and is also locked to the back surface Kb. An upper surface 38a of 38 (a surface facing the substrate K) is locked. On the other hand, the opening portion 21 of the case 20 is extended downward from the outer shape of the hood portion 12 fitted therein, and the locking piece 38 of the restricting portion 36 described above can be inserted into the extended portion 21a. Yes.

本実施形態は以上のような構造であり、続いてその作用を説明する。各雄端子金具14及び両固定金具17を装着した雄ハウジング10を基板Kの表面Kaにおける所定位置にセットするとともに、各雄端子金具14の基板側接続部14bと、両固定金具17の半田付け部17bとをそれぞれ半田付けする。すると、各雄端子金具14が基板Kに固着されて導電路に対して電気的に接続されるとともに、半田付けされた両固定金具17により雄ハウジング10が基板Kに対して取付状態に固定される。この状態で雄ハウジング10を基板Kと共にケース20内に収容すると、図4に示すように、雄ハウジング10は、ケース20の開口部21に臨んで配され、そこに内嵌されたフード部12が外部に開口した状態とされる。この状態で雄ハウジング10に対して別途に組み付けておいた雌ハウジング30を嵌合する作業を行う。   This embodiment has the structure as described above, and the operation thereof will be described subsequently. The male housing 10 to which each male terminal fitting 14 and both fixing fittings 17 are mounted is set at a predetermined position on the surface Ka of the board K, and the board-side connecting portion 14b of each male terminal fitting 14 and the both fixing fittings 17 are soldered. Each of the parts 17b is soldered. Then, each male terminal fitting 14 is fixed to the board K and is electrically connected to the conductive path, and the male housing 10 is fixed to the board K in the attached state by the soldered fixing fittings 17. The When the male housing 10 is accommodated in the case 20 together with the substrate K in this state, as shown in FIG. 4, the male housing 10 is arranged facing the opening 21 of the case 20, and the hood portion 12 fitted therein. Is opened to the outside. In this state, an operation of fitting the female housing 30 separately assembled to the male housing 10 is performed.

雌ハウジング30をフード部12内に嵌合すると、ロック突部35が被ロック部15により押圧されることで、ロックアーム34が一旦下方へ弾性変形させられる。そして、雌ハウジング30が雄ハウジング10に対して正規深さまで嵌合されると、図5に示すように、ロック突部35が被ロック部15の後方位置に達してロックアーム34が復元するとともにロック突部35の後面に被ロック部15の後面が係止される。これにより、両ハウジング10,30が正規の嵌合状態から離脱不能に保持される。この正規嵌合時には、各雌端子金具31の弾性接触片31cが各雄端子金具14のコネクタ側接続部14aに対して弾性接触することで、両端子金具14,31が正規に導通接続される。   When the female housing 30 is fitted into the hood portion 12, the lock protrusion 35 is pressed by the locked portion 15, whereby the lock arm 34 is once elastically deformed downward. When the female housing 30 is fitted to the male housing 10 to a normal depth, the lock projection 35 reaches the rear position of the locked portion 15 and the lock arm 34 is restored as shown in FIG. The rear surface of the locked portion 15 is locked to the rear surface of the lock protrusion 35. Thereby, both the housings 10 and 30 are hold | maintained so that it cannot detach | leave from a normal fitting state. At the time of this regular fitting, the elastic contact pieces 31c of the respective female terminal fittings 31 are brought into elastic contact with the connector side connection portions 14a of the respective male terminal fittings 14, so that both the terminal fittings 14 and 31 are normally conductively connected. .

さて、両ハウジング10,30を嵌合する際には、雌ハウジング30の規制部36が開口部21の拡張部分21aに挿通される。詳しくは、規制部36のうち係止片38は、両ハウジング10,30の嵌合に伴って開口部21の拡張部分21aを通って基板Kの裏側に差し込まれて先端が基板Kの前端位置よりも所定深さだけ奥側位置に達するとともに、その上面38aが基板Kの裏面Kbに対して係止される。従って、両ハウジング10,30が嵌合した状態において、例えば雌ハウジング30から外部へと引き出された各電線Wが上方へ向けて引っ張られ、雌ハウジング30を基板Kとは反対側の方向(基板Kから離間する方向)へ持ち上げるような力が作用した場合でも、規制部36の係止片38が基板Kの裏面Kbに係止することで、雄ハウジング10が雌ハウジング30と共に基板Kから離間する方向へ変位しようする動作が規制される。これにより、固定金具17を基板Kに固定している半田にクラックが入るなどして雄ハウジング10が基板Kから外れるような事態を防ぐことができる。   Now, when fitting both the housings 10 and 30, the restricting portion 36 of the female housing 30 is inserted into the extended portion 21 a of the opening 21. Specifically, the locking piece 38 of the restricting portion 36 is inserted into the back side of the substrate K through the extended portion 21 a of the opening 21 with the fitting of the housings 10 and 30, and the tip is the front end position of the substrate K. The upper surface 38 a is locked to the rear surface Kb of the substrate K while reaching the rear side position by a predetermined depth. Therefore, in a state where both housings 10 and 30 are fitted, for example, each electric wire W drawn out from the female housing 30 is pulled upward, and the female housing 30 is pulled in a direction opposite to the board K (board). Even when a force that lifts in the direction away from K) is applied, the locking piece 38 of the restricting portion 36 is locked to the back surface Kb of the board K, so that the male housing 10 is separated from the board K together with the female housing 30. The movement to move in the direction to be controlled is restricted. As a result, it is possible to prevent a situation in which the male housing 10 is detached from the substrate K due to cracks in the solder fixing the fixing bracket 17 to the substrate K.

以上説明したように本実施形態によれば、雌ハウジング30に基板Kの裏面Kbに係止可能な規制部36を設けるようにしたから、嵌合状態において雄ハウジング10が雌ハウジング30と共に基板Kから離間する方向へ変位するのが規制され、もって基板Kから雄ハウジング10が外れるような事態を防ぐことができる。   As described above, according to this embodiment, since the female housing 30 is provided with the restricting portion 36 that can be locked to the back surface Kb of the substrate K, the male housing 10 and the female housing 30 together with the female housing 30 in the fitted state. Therefore, it is possible to prevent the male housing 10 from being detached from the substrate K.

しかも、ケース20に設けた開口部21を拡張することで、規制部36の挿通を許容するようにしたから、仮に開口部21とは別途に規制部36を挿通するための専用の開口をケース20に設けるようにした場合と比較すると、構造を簡素化することができる。   In addition, since the opening portion 21 provided in the case 20 is expanded to allow the insertion of the restricting portion 36, a dedicated opening for inserting the restricting portion 36 separately from the opening portion 21 is provided in the case. Compared with the case where it is provided at 20, the structure can be simplified.

<実施形態2>
本発明の実施形態2を図6または図7によって説明する。この実施形態2では、ケース20に規制部36Aが係止可能な係止孔22を設けるようにしたものを示す。なおこの実施形態2では、上記した実施形態1と同様の構造、作用及び効果について重複する説明は省略する。
<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. 6 or FIG. In the second embodiment, the case 20 is provided with a locking hole 22 in which the restricting portion 36A can be locked. In the second embodiment, redundant description of the same structure, operation, and effects as those in the first embodiment will be omitted.

ケース20には、図6に示すように、雄ハウジング10のフード部12が内嵌される開口部21Aが設けられており、この開口部21Aは、フード部12の外形に沿う形状とされ、大きさもフード部12とほぼ同じに設定されている(実施形態1に示したような拡張部分21aが省略されている)。そして、ケース20における開口部21Aの少し下方位置には、雌ハウジング30の規制部36Aが挿入可能とされる係止孔22が開口して設けられている。係止孔22の開口間口は、係止片38Aの厚み寸法及び幅寸法にほぼ適合するような大きさとされる。一方、規制部36Aは、突出部37Aの下方への突出寸法が係止孔22の配設位置に対応した大きさとされているので、嵌合時には係止片38Aが係止孔22に整合して挿入されるようになっている。   As shown in FIG. 6, the case 20 is provided with an opening 21 </ b> A into which the hood portion 12 of the male housing 10 is fitted. The opening 21 </ b> A has a shape that follows the outer shape of the hood portion 12. The size is also set to be substantially the same as that of the hood portion 12 (the extended portion 21a as shown in the first embodiment is omitted). A locking hole 22 into which the restricting portion 36 </ b> A of the female housing 30 can be inserted is provided at a position slightly below the opening 21 </ b> A in the case 20. The opening opening of the locking hole 22 is sized to substantially match the thickness dimension and the width dimension of the locking piece 38A. On the other hand, since the restricting portion 36A has a protruding dimension below the protruding portion 37A corresponding to the position where the locking hole 22 is disposed, the locking piece 38A is aligned with the locking hole 22 when fitted. Are to be inserted.

雄ハウジング10のフード部12内に雌ハウジング30を嵌合すると、図7に示すように、規制部36Aの係止片38Aが係止孔22内に差し込まれてその上面38Aaが係止孔22の周面のうち上面22a(周面のうち雄ハウジング10側の面)に対して係止される。従って、両ハウジング10,30が嵌合した状態から雌ハウジング30を基板Kから離間する方向へ持ち上げるような力が作用した場合でも、雄ハウジング10が雌ハウジング30と共に基板Kから離間する方向へ変位するのが規制され、もって雄ハウジング10が基板Kから外れるような事態を回避することができる。   When the female housing 30 is fitted into the hood portion 12 of the male housing 10, as shown in FIG. 7, the locking piece 38 </ b> A of the restricting portion 36 </ b> A is inserted into the locking hole 22, and the upper surface 38 </ b> Aa thereof is the locking hole 22. Is locked to the upper surface 22a (the surface on the male housing 10 side of the peripheral surface). Therefore, even when a force is applied to lift the female housing 30 in the direction away from the board K from the state in which both the housings 10 and 30 are fitted, the male housing 10 is displaced together with the female housing 30 in the direction away from the board K. Therefore, a situation in which the male housing 10 is detached from the substrate K can be avoided.
