The holding rod 103 is inserted into a rod insertion hole 112 of the seal member 110 and a rod insertion hole (not shown) of the seal holder 120, respectively. The seal member 110 is held between the connector housing 101 and the seal holder 120. Terminals (not shown) to which electric wires (not shown) are connected are accommodated in the terminal accommodating chambers 102 of the connector housing 101, respectively. The electric wires connected to the terminals are drawn out through the electric wire insertion holes 111 of the seal member 110 and the electric wire insertion holes 121 of the seal holder 120, respectively.
　下記特許文献２は、他の従来の防水コネクタ１３０を開示している。図１２に示されるように、コネクタ１３０は、端子収容室１５１を有するコネクタハウジング１５０と、複数の電線挿通孔１４１を有するシール部材１４０と、複数の電線挿通孔１３２を有するシールホルダ１３１とを備えている。シールホルダ１３１には、保持ロッド１３３が設けられている。保持ロッド１３３は、それぞれ、シール部材１４０のロッド挿入穴１４２とコネクタハウジング１５０の挿入溝１５２とに挿入される。シール部材１４０は、コネクタハウジング１５０とシールホルダ１３１とに挟まれて保持されている。電線（図示せず）が接続された端子（図示せず）は、それぞれ、コネクタハウジング１５０の端子収容室１５１に収容される。端子に接続された電線は、それぞれ、シール部材１４０の電線挿通孔１４１とシールホルダ１３１の電線挿通孔１３２とを通って外部に引き出される。 The following Patent Document 2 discloses another conventional waterproof connector 130. As shown in FIG. 12, the connector 130 includes a connector housing 150 having a terminal accommodating chamber 151, a seal member 140 having a plurality of wire insertion holes 141, and a seal holder 131 having a plurality of wire insertion holes 132. ing. The seal holder 131 is provided with a holding rod 133. The holding rod 133 is inserted into the rod insertion hole 142 of the seal member 140 and the insertion groove 152 of the connector housing 150, respectively. The seal member 140 is held between the connector housing 150 and the seal holder 131. Terminals (not shown) to which electric wires (not shown) are connected are accommodated in the terminal accommodating chambers 151 of the connector housing 150, respectively. The electric wires connected to the terminals are drawn out through the electric wire insertion holes 141 of the seal member 140 and the electric wire insertion holes 132 of the seal holder 131, respectively.
　上述したコネクタ１００（１３０）では、電線がシール部材１１０（１４０）の電線挿通孔１１１（１４１）に挿通され、電線挿通孔１１１（１４１）の内周面が電線に密着されるので、電線の引出箇所からコネクタ１００（１３０）の内部への水の浸入が防止されている。また、シール部材１１０（１４０）の外周面が、コネクタ１００（１３０）の相手部材[mating member]の内周面に密着されるので、一対のコネクタハウジングの嵌合部からの水の浸入が防止されている。特許文献１に開示されたコネクタ１００の相手部材は、バスバー体（図示せず）を覆うキャップ（図示せず）であり、特許文献２に開示されたコネクタ１３０の相手部材は相手コネクタハウジング（図示せず）である。 In the connector 100 (130) described above, the electric wire is inserted into the electric wire insertion hole 111 (141) of the seal member 110 (140), and the inner peripheral surface of the electric wire insertion hole 111 (141) is in close contact with the electric wire. Water is prevented from entering the connector 100 (130) from the drawn portion. In addition, since the outer peripheral surface of the seal member 110 (140) is in close contact with the inner peripheral surface of the mating member [mating member] of the connector 100 (130), water can be prevented from entering from the fitting portion of the pair of connector housings. Has been. The mating member of the connector 100 disclosed in Patent Literature 1 is a cap (not shown) that covers a bus bar body (not shown), and the mating member of the connector 130 disclosed in Patent Literature 2 is a mating connector housing (see FIG. Not shown).
　このように、従来のコネクタ１００（１３０）では、シール部材１１０（１４０）が、複数の電線の引出箇所をシールすると共に、相手部材のハウジングとの嵌合部をシールする。この結果、部品点数が削減されている。下記特許文献３に記載の防水コネクタも同様の構造を有している。 Thus, in the conventional connector 100 (130), the seal member 110 (140) seals the drawing portion of the plurality of electric wires and seals the mating portion of the mating member with the housing. As a result, the number of parts is reduced. The waterproof connector described in Patent Document 3 below has a similar structure.

　しかし、シール部材１１０（１４０）は、コネクタハウジング１０１（１５０）とシールホルダ１２０（１３１）とによって挟まれることで保持されている。このため、コネクタ１００（１３０）には、シールホルダ１２０（１３１）のためのスペースが必要であり、コネクタ１００（１３０）の小型化を阻害されていた。 However, the seal member 110 (140) is held by being sandwiched between the connector housing 101 (150) and the seal holder 120 (131). For this reason, the connector 100 (130) requires a space for the seal holder 120 (131), which hinders the miniaturization of the connector 100 (130).
　本発明の目的は、さらなる小型化が可能な防水コネクタを提供することである。 An object of the present invention is to provide a waterproof connector that can be further reduced in size.
　本発明の特徴は、防水コネクタであって、端子をそれぞれ収容する複数の端子収容室を有し、前記複数の端子収容室からの電線の引出側から前記端子が挿入されて前記端子収容室に収容されるインナーハウジングと、前記インナーハウジングの前記引出側に配置され、前記端子に接続される前記電線がそれぞれ挿通される複数の電線挿通孔が形成されて前記複数の電線挿通孔の内面が前記電線に密着されるシール部材と、前記インナーハウジング及び前記シール部材を収容するハウジング収容室を内部に有し、前記ハウジング収容室の内周面と前記インナーハウジング及び前記シール部材の外周面との間に、相手ハウジングが挿入される相手ハウジング挿入エリアを形成するアウターハウジングと、を備え、前記アウターハウジングに、前記インナーハウジング及び前記シール部材を保持する保持ロッドが突設され、前記相手ハウジングが、前記相手ハウジング挿入エリアの挿入完了位置にまで挿入された時に、前記シール部材の外周面が前記相手ハウジングの内周面に密着される、防水コネクタを提供する。 A feature of the present invention is a waterproof connector, which has a plurality of terminal accommodating chambers that respectively accommodate terminals, and the terminals are inserted into the terminal accommodating chambers from the wire drawing side from the plurality of terminal accommodating chambers. An inner housing to be accommodated, and a plurality of electric wire insertion holes which are arranged on the drawing side of the inner housing and into which the electric wires connected to the terminals are respectively inserted, and the inner surfaces of the electric wire insertion holes are A seal member that is in close contact with the electric wire, and a housing housing chamber that houses the inner housing and the seal member are provided therein, and the space between the inner circumferential surface of the housing housing chamber and the outer circumferential surface of the inner housing and the seal member. And an outer housing that forms a mating housing insertion area into which the mating housing is inserted. When the holding rod for holding the inner housing and the seal member is protruded and the mating housing is inserted to the insertion completion position of the mating housing insertion area, the outer peripheral surface of the seal member is the inner circumference of the mating housing. Provided is a waterproof connector that is in close contact with a surface.
　上記特徴によれば、シール部材がインナーハウジングとアウターハウジングとの間に挟まれて保持されるので、専用のシールホルダが不要であり、部品スペースを削減できる。シール部材が電線の引出箇所をシールするだけでなく、相手ハウジングとの嵌合部もシールするので、相手ハウジングと嵌合部をシールする専用のシール部材が不要であり、部品スペースを削減できる。従って、防水コネクタを小型化することができる。 According to the above feature, since the seal member is sandwiched and held between the inner housing and the outer housing, a dedicated seal holder is unnecessary, and the part space can be reduced. Since the seal member not only seals the drawing portion of the electric wire, but also seals the fitting portion with the mating housing, a dedicated seal member for sealing the mating housing and the mating portion is unnecessary, and the part space can be reduced. Therefore, the waterproof connector can be reduced in size.
　前記保持ロッドが、撓み変形可能である、ことが好ましい。前記保持ロッドが、前記相手ハウジング挿入エリアよりも内方に設けられている、ことが好ましい。前記インナーハウジングが、前記複数の端子収容室と共に複数のショート端子収容室を有し、前記ショート端子収容室の後方に前記保持ロッドが挿入されるロッド挿入穴が設けられている、ことが好ましい。 It is preferable that the holding rod can be bent and deformed. It is preferable that the holding rod is provided inward of the mating housing insertion area. Preferably, the inner housing has a plurality of short terminal accommodating chambers together with the plurality of terminal accommodating chambers, and a rod insertion hole into which the holding rod is inserted is provided behind the short terminal accommodating chamber.
　前記アウターハウジングが、前面が開口された箱形状を有しており、前記保持ロッドが、箱形状を有する前記前記アウターハウジングの後壁から突設されており、前記シール部材を前記後壁から離間した位置に仮保持する仮保持部が、前記保持ロッドに形成されている、ことが好ましい。 The outer housing has a box shape with an open front surface, the holding rod protrudes from a rear wall of the outer housing having a box shape, and the seal member is separated from the rear wall. It is preferable that a temporary holding portion for temporarily holding at the position is formed on the holding rod.
　このようにすれば、シール部材は、仮保持部によって後壁から離間した位置で仮保持される。ロッド部材が仮保持されたシール部材によって位置決めされるので、ロッド部材は、芯振れが抑制された正規の位置に配置される。このため、ロッド部材にインナーハウジングを容易に取り付けることができる。 In this way, the seal member is temporarily held at a position separated from the rear wall by the temporary holding portion. Since the rod member is positioned by the temporarily held seal member, the rod member is disposed at a normal position where the center runout is suppressed. For this reason, an inner housing can be easily attached to a rod member.
　前記保持ロッドの先端に係止爪が形成されており、前記インナーハウジングに、前記保持ロッドが挿入されるロッド挿入穴が形成されており、前記ロッド挿入穴の内部に、前記インナーハウジングと前記アウターハウジングとの嵌合時に前記係止爪と係止する係止凹部が形成されている、ことが好ましい。 A locking claw is formed at the tip of the holding rod, and a rod insertion hole into which the holding rod is inserted is formed in the inner housing, and the inner housing and the outer housing are formed inside the rod insertion hole. It is preferable that a locking recess for locking with the locking claw when fitted to the housing is formed.
　このようにすれば、インナーハウジングとアウターハウジングとの嵌合が完了すると、係止爪が係止凹部と係止される。これにより、インナーハウジングは、アウターハウジングからの離脱が規制される。シール部材は、アウターハウジングと、アウターハウジングからの離脱が規制されたインナーハウジングとによって挟まれて保持され、水密性を発揮する。 In this way, when the fitting between the inner housing and the outer housing is completed, the locking claw is locked with the locking recess. Thereby, the inner housing is restricted from being detached from the outer housing. The seal member is sandwiched and held between the outer housing and the inner housing in which separation from the outer housing is restricted, and exhibits water tightness.
　前記仮保持部が、前記保持ロッドの先端側に形成された小径部と前記保持ロッドの基端側に形成された大径部との間に設けられた段部である、ことが好ましい。 It is preferable that the temporary holding portion is a step provided between a small diameter portion formed on the distal end side of the holding rod and a large diameter portion formed on the proximal end side of the holding rod.
　このようにすれば、シール部材は、段部に当接することで、ロッド部材に対して直角に仮保持され、その後、インナーハウジングによって押し込まれる際に、高精度に平行移動さ得る。 In this way, the seal member can be temporarily held at a right angle with respect to the rod member by abutting against the stepped portion, and can then be translated with high accuracy when being pushed by the inner housing.

　各保持ロッド２３は、図１０（ａ）中の矢印によって示されるように、撓み変形可能な円柱である。各位置決めロッド５９も撓み変形可能である。各保持ロッド２３の先端には、係止爪２３ａが設けられている。各位置決めロッド５９の先端には、係止爪は設けられていない。保持ロッド２３がインナーハウジング２のロッド挿入穴７に完全に挿入されると、係止爪２３ａがロッド挿入穴７内に形成された係止凹部６１（図９参照）と係止される。この結果、インナーハウジング２及びシール部材１０は、脱落しないようにアウターハウジング２０によって保持される。 Each holding rod 23 is a cylinder that can be bent and deformed, as indicated by an arrow in FIG. Each positioning rod 59 can also be bent and deformed. A locking claw 23 a is provided at the tip of each holding rod 23. A locking claw is not provided at the tip of each positioning rod 59. When the holding rod 23 is completely inserted into the rod insertion hole 7 of the inner housing 2, the locking claw 23 a is locked with a locking recess 61 (see FIG. 9) formed in the rod insertion hole 7. As a result, the inner housing 2 and the seal member 10 are held by the outer housing 20 so as not to drop off.
　図６に示されるように、保持ロッド２３及び位置決めロッド５９には、それぞれ、仮保持部１９が形成されている。仮保持部１９は、ロッド２３及び５９の外周に形成されており、図７（ｂ）、図８（ｂ）及び図９に示されるように、シール部材１０を後壁２０ａから離間した位置に仮保持させる。仮保持部１９は、保持ロッド２３及び位置決めロッド５９の先端側に形成された小径部６３と基端側に形成された大径部６５との間に設けられた段差として形成されている。 As shown in FIG. 6, temporary holding portions 19 are formed on the holding rod 23 and the positioning rod 59, respectively. The temporary holding portion 19 is formed on the outer periphery of the rods 23 and 59, and as shown in FIGS. 7B, 8B, and 9, the seal member 10 is located at a position separated from the rear wall 20a. Temporarily hold. The temporary holding portion 19 is formed as a step provided between a small diameter portion 63 formed on the distal end side of the holding rod 23 and the positioning rod 59 and a large diameter portion 65 formed on the proximal end side.
　リテーナ３０は、インナーハウジング２のリテーナ装着口３３内に装着される。リテーナ３０は、合成樹脂製であり、平板形状を有している。リテーナ３０には、端子収容室３に対応する端子挿通孔６７（図１参照）が形成されている。リテーナ３０は、端子収容室３への端子５の挿入を許容する仮係止位置と端子収容室３に収容された端子５を係止する本係止位置との間で変位可能である。リテーナ３０は、仮係止位置にあるとき、係止突起３０ａ（図５（ｂ）参照）が端子収容室３の外に退避して端子５の挿通を許容する。一方、リテーナ３０が押し込まれて仮係止位置から本係止位置へと上方移動されると、係止突起が端子収容室３内に進入し、係止突起３０ａによって、端子収容室３内に挿入された端子５の後方への抜けが防止される。 The retainer 30 is mounted in the retainer mounting port 33 of the inner housing 2. The retainer 30 is made of a synthetic resin and has a flat plate shape. A terminal insertion hole 67 (see FIG. 1) corresponding to the terminal accommodating chamber 3 is formed in the retainer 30. The retainer 30 is displaceable between a temporary locking position that allows insertion of the terminal 5 into the terminal accommodating chamber 3 and a final locking position that locks the terminal 5 accommodated in the terminal accommodating chamber 3. When the retainer 30 is in the temporary locking position, the locking protrusion 30a (see FIG. 5B) is retracted out of the terminal accommodating chamber 3 and allows the terminal 5 to be inserted. On the other hand, when the retainer 30 is pushed in and moved upward from the temporary locking position to the final locking position, the locking protrusion enters the terminal accommodating chamber 3 and is moved into the terminal accommodating chamber 3 by the locking protrusion 30a. The inserted terminal 5 is prevented from coming out backward.
　図３（ｂ）に示されるように、アウターハウジング２０の内周面とインナーハウジング２及びシール部材１０の外周面との間には、相手ハウジング挿入エリアＥが形成される。相手ハウジング５０が相手ハウジング挿入エリアＥに完全に挿入されると、シール部材１０の外周面のリップ部１１ｂが相手ハウジング５０の内周面に密着される。この結果、相手ハウジング５０とインナーハウジング２との嵌合部からの水の浸入が防止される。相手ハウジング５０は、アウターハウジング２０とシール部材１０との間に保持されるので、シール部材１０は確実に相手ハウジング５０に密着される。この結果、高い防水性が発揮される。 3 (b), a mating housing insertion area E is formed between the inner peripheral surface of the outer housing 20 and the outer peripheral surfaces of the inner housing 2 and the seal member 10. When the mating housing 50 is completely inserted into the mating housing insertion area E, the lip portion 11 b of the outer peripheral surface of the seal member 10 is brought into close contact with the inner peripheral surface of the mating housing 50. As a result, entry of water from the fitting portion between the mating housing 50 and the inner housing 2 is prevented. Since the mating housing 50 is held between the outer housing 20 and the seal member 10, the seal member 10 is securely attached to the mating housing 50. As a result, high waterproofness is exhibited.
　アウターハウジング２０の後壁２０ａには、インナーハウジング２の端子収容室３及びシール部材１０の電線挿通孔１１に対向する位置に、複数の電線挿通孔２４が形成されている。 A plurality of wire insertion holes 24 are formed in the rear wall 20 a of the outer housing 20 at positions facing the terminal accommodating chamber 3 of the inner housing 2 and the wire insertion holes 11 of the seal member 10.
　レバー４０は、アウターハウジング２０の上部のレバー収容室２２内に組み込まれ、相手コネクタとの嵌合時に操作される。レバー４０の支持軸６９は、アウターハウジング２０の軸孔７１に支持される。コネクタ１と相手ハウジング５０との嵌合時には、相手コネクタのカムピン（図示せず）がレバー４０のカム溝７３に導入され、レバー４０が回動初期位置から図２の反時計周りに回転されることで、相手ハウジング５０を低挿入力で相手ハウジング挿入エリアＥに挿入できる。 The lever 40 is incorporated in the lever housing chamber 22 at the top of the outer housing 20 and is operated when mated with the mating connector. The support shaft 69 of the lever 40 is supported by the shaft hole 71 of the outer housing 20. When the connector 1 is mated with the mating housing 50, the cam pin (not shown) of the mating connector is introduced into the cam groove 73 of the lever 40, and the lever 40 is rotated counterclockwise in FIG. Thus, the mating housing 50 can be inserted into the mating housing insertion area E with a low insertion force.
　次に、コネクタ１の組み付け手順を簡単に説明する。アウターハウジング２０には既にレバー４０が装着されている。図５（ａ）に示すように、保持ロッド２３にシール部材１０のロッド挿入孔１２を挿入して、ハウジング収容室２１にシール部材１０を取り付ける。 Next, the procedure for assembling the connector 1 will be briefly described. The lever 40 is already attached to the outer housing 20. As shown in FIG. 5A, the rod insertion hole 12 of the seal member 10 is inserted into the holding rod 23 and the seal member 10 is attached to the housing accommodation chamber 21.
　このとき、アウターハウジング２０の後壁２０ａから突出された保持ロッド２３及び位置決めロッド５９は、それぞれ、シール部材１０のロッド挿入孔１２及び１３に挿入される。シール部材１０は、図７（ｂ）、図８（ｂ）及び図９に示されるように、仮保持部１９と当接して、後壁２０ａへの移動が一時的に規制される。即ち、シール部材１０は、仮保持部１９によって、後壁２０ａから離間した位置に仮保持される。この結果、保持ロッド２３及び位置決めロッド５９は、シール部材１０によって先端の芯振れが抑制され、正規の位置に位置決めされる。 At this time, the holding rod 23 and the positioning rod 59 protruding from the rear wall 20a of the outer housing 20 are inserted into the rod insertion holes 12 and 13 of the seal member 10, respectively. As shown in FIG. 7B, FIG. 8B, and FIG. 9, the seal member 10 comes into contact with the temporary holding portion 19, and the movement to the rear wall 20a is temporarily restricted. That is, the seal member 10 is temporarily held by the temporary holding portion 19 at a position separated from the rear wall 20a. As a result, the holding rod 23 and the positioning rod 59 are positioned at their normal positions with the centering of the tip thereof suppressed by the seal member 10.
　次に、リテーナ３０を、インナーハウジング２に取り付け、仮係止位置にセットしておく。そして、保持ロッド２３及び位置決めロッド５９をインナーハウジング２のロッド挿入穴７及び４３に挿入し、インナーハウジング２をアウターハウジング２０に取り付ける。このとき、保持ロッド２３及び位置決めロッド５９は正規の位置に位置決めされているので、保持ロッド２３（位置決めロッド５９）の先端がロッド挿入穴７（４３）の開口縁７ａ（図９参照）に突き当たることはなく、保持ロッド２３及び位置決めロッド５９は円滑にロッド挿入穴７及び４３に挿入される。その後、インナーハウジング２の先端面はシール部材１０と当接した後、仮保持されていたシール部材１０をさらに押し込む。 Next, the retainer 30 is attached to the inner housing 2 and set at the temporary locking position. Then, the holding rod 23 and the positioning rod 59 are inserted into the rod insertion holes 7 and 43 of the inner housing 2, and the inner housing 2 is attached to the outer housing 20. At this time, since the holding rod 23 and the positioning rod 59 are positioned at regular positions, the tip of the holding rod 23 (positioning rod 59) hits the opening edge 7a (see FIG. 9) of the rod insertion hole 7 (43). The holding rod 23 and the positioning rod 59 are smoothly inserted into the rod insertion holes 7 and 43. Thereafter, after the front end surface of the inner housing 2 comes into contact with the seal member 10, the temporarily held seal member 10 is further pushed in.
　図８（ｃ）に示されるように、インナーハウジング２が所定位置まで挿入されると、保持ロッド２３の係止爪２３ａがロッド挿入穴７内の係止凹部６１（図９参照）と係止される。この結果、インナーハウジング２は、アウターハウジング２０から離脱不能に固定される。シール部材１０は、弾性変形によってロッド挿入孔１２及び１３が拡径され、仮保持部１９を通過することができる。シール部材１０は、インナーハウジング２及び後壁２０ａに挟まれて押圧され、インナーハウジング２と後壁２０ａとの間の水密性を確保する。 As shown in FIG. 8C, when the inner housing 2 is inserted to a predetermined position, the locking claw 23a of the holding rod 23 is locked with the locking recess 61 (see FIG. 9) in the rod insertion hole 7. Is done. As a result, the inner housing 2 is fixed so as not to be detached from the outer housing 20. The seal member 10 can pass through the temporary holding part 19 by expanding the diameter of the rod insertion holes 12 and 13 by elastic deformation. The seal member 10 is sandwiched and pressed between the inner housing 2 and the rear wall 20a to ensure water tightness between the inner housing 2 and the rear wall 20a.
　次に、電線Ｗが接続された端子５を、アウターハウジング２０の後壁２０ａから、電線挿通孔２４及び電線挿通孔１１を通して、端子収容室３に収容する。全ての端子５が端子収容室３に挿入された後、リテーナ３０が仮係止位置から本係止位置に移動される。端子５は、インナーハウジング２のランス（図示せず）とリテーナ３０とによって係止され、引き抜き方向の移動が阻止される。また、端子５が接続された電線Ｗは、電線挿通孔１１及び電線挿通孔２４からコネクタ１の外部に引き出される。電線Ｗは、電線挿通孔１１の内面に突設されたリップ部１１ａと密着し、電線Ｗの引出箇所からの水の浸入が防止される。 Next, the terminal 5 to which the electric wire W is connected is accommodated in the terminal accommodating chamber 3 from the rear wall 20a of the outer housing 20 through the electric wire insertion hole 24 and the electric wire insertion hole 11. After all the terminals 5 are inserted into the terminal accommodating chamber 3, the retainer 30 is moved from the temporary locking position to the final locking position. The terminal 5 is locked by a lance (not shown) of the inner housing 2 and the retainer 30 and is prevented from moving in the pulling direction. Further, the electric wire W to which the terminal 5 is connected is drawn out of the connector 1 from the electric wire insertion hole 11 and the electric wire insertion hole 24. The electric wire W is in close contact with the lip portion 11a projecting from the inner surface of the electric wire insertion hole 11, and water intrusion from the location where the electric wire W is drawn is prevented.
　続いて、ショート端子６が所望のショート端子収容室４に挿入される。このようにして、コネクタ１の組立作業が完了する。 Subsequently, the short terminal 6 is inserted into the desired short terminal accommodating chamber 4. In this way, the assembly work of the connector 1 is completed.
　次に、コネクタ１への相手ハウジング５０の挿入について説明する。相手ハウジング５０が相手ハウジング挿入エリアＥと位置合わせされ、レバー４０との係止ポイントまで相手ハウジング５０が相手ハウジング挿入エリアＥに挿入される。次に、レバー４０が回転されると、レバー４０と相手ハウジング５０との間のカム機構によって、相手ハウジング５０が相手ハウジング挿入エリアＥに徐々に挿入される。相手ハウジング５０が挿入完了位置まで挿入されると、コネクタ１への相手ハウジング５０の挿入が完了する。挿入完了位置では、相手ハウジング５０内のオス端子（図示せず）とメス端子５が適正に接触して、電気的に導通される。相手ハウジング５０が挿入完了位置にあるとき、図３（ｂ）に示されるように、シール部材１０の外周面のリップ部１１ｂが相手ハウジング５０の内周面に密着される。 Next, the insertion of the mating housing 50 into the connector 1 will be described. The mating housing 50 is aligned with the mating housing insertion area E, and the mating housing 50 is inserted into the mating housing insertion area E up to the locking point with the lever 40. Next, when the lever 40 is rotated, the mating housing 50 is gradually inserted into the mating housing insertion area E by the cam mechanism between the lever 40 and the mating housing 50. When the mating housing 50 is inserted to the insertion completion position, the mating housing 50 is completely inserted into the connector 1. At the insertion completion position, the male terminal (not shown) in the mating housing 50 and the female terminal 5 are in proper contact and are electrically connected. When the mating housing 50 is in the insertion completion position, the lip portion 11b on the outer circumferential surface of the seal member 10 is brought into close contact with the inner circumferential surface of the mating housing 50 as shown in FIG.
　以上説明したように、アウターハウジング２０には、インナーハウジング２及びシール部材１０を保持する保持ロッド２３が突設されている。従って、シール部材１０がインナーハウジング２とアウターハウジング２０とに挟まれて保持されるので、上述した従来の防水コネクタ１００及び１３０におけるシールホルダ１２０及び１５０（図７（ａ）及び図８参照）が不要であり、部品スペースを削減できる。また、相手ハウジング５０が相手ハウジング挿入エリアＥに挿入されて挿入完了位置に位置されると、シール部材１０の外周面が相手ハウジング５０の内周面に密着される。従って、シール部材１０は、電線Ｗの引出箇所をシールするだけでなく、相手ハウジング５０との嵌合部もシールするので、相手ハウジング５０と嵌合部をシールする専用の部材が不要であり、部品スペースを削減できる。従って、防水コネクタ１を小型化できる。 As described above, the outer housing 20 is provided with the holding rod 23 for holding the inner housing 2 and the seal member 10. Therefore, since the seal member 10 is sandwiched and held between the inner housing 2 and the outer housing 20, the seal holders 120 and 150 (see FIGS. 7A and 8) in the conventional waterproof connectors 100 and 130 described above. This is unnecessary and can reduce the part space. When the mating housing 50 is inserted into the mating housing insertion area E and positioned at the insertion completion position, the outer peripheral surface of the seal member 10 is brought into close contact with the inner peripheral surface of the mating housing 50. Therefore, the seal member 10 not only seals the drawing portion of the electric wire W but also seals the fitting portion with the mating housing 50, so that a dedicated member for sealing the mating housing 50 and the fitting portion is unnecessary. Parts space can be reduced. Therefore, the waterproof connector 1 can be reduced in size.
　保持ロッド２３は、撓み変形可能である。従って、図１０（ｂ）に示されるように、アウターハウジング２０に対するインナーハウジング２の傾斜は、保持ロッド２３の撓み変形とシール部材１０の圧縮弾性変形とで吸収される。相手ハウジング５０が傾斜して挿入されても、インナーハウジング２が傾斜して相手ハウジング５０との干渉を軽減・解消する。この結果、コネクタ挿入力を軽減でき、また、オス端子とメス端子５との間のこじりも軽減できる。 The holding rod 23 can be bent and deformed. Therefore, as shown in FIG. 10B, the inclination of the inner housing 2 with respect to the outer housing 20 is absorbed by the bending deformation of the holding rod 23 and the compression elastic deformation of the seal member 10. Even if the mating housing 50 is inserted at an angle, the inner housing 2 is tilted to reduce or eliminate interference with the mating housing 50. As a result, the connector insertion force can be reduced, and the twisting between the male terminal and the female terminal 5 can be reduced.
　保持ロッド２３は、相手ハウジング挿入エリアＥよりも内方に設けられている。従って、保持ロッド２３の設置によってコネクタ１の小型化が阻害されることがない。 The holding rod 23 is provided inward of the mating housing insertion area E. Therefore, the size reduction of the connector 1 is not hindered by the installation of the holding rod 23.
　インナーハウジング２は端子収容室３と共にショート端子収容室４を有し、前方から見てショート端子収容室４の後方に、保持ロッド２３が挿入されるロッド挿入穴７が形成されている。従って、ショート端子収容室４の後方のデッドスペースを利用して、インナーハウジング２及びシール部材１０をアウターハウジング２０に取り付ける機構を設けたので、コネクタ１を小型化できる。 The inner housing 2 has a short terminal accommodating chamber 4 together with the terminal accommodating chamber 3, and a rod insertion hole 7 into which the holding rod 23 is inserted is formed at the rear of the short terminal accommodating chamber 4 when viewed from the front. Therefore, since the mechanism for attaching the inner housing 2 and the seal member 10 to the outer housing 20 is provided using the dead space behind the short terminal accommodating chamber 4, the connector 1 can be reduced in size.
　相手ハウジング５０の挿入方向に沿って、インナーハウジング２、シール部材１０、及び、アウターハウジング２０の後壁２０ａが順に配置されている。このため、相手ハウジング５０等からの外力（荷重）がインナーハウジング２に作用しても、シール部材１０の弾性変形で吸収でき、インナーハウジング２のダメージを低減できる。 The inner housing 2, the seal member 10, and the rear wall 20a of the outer housing 20 are arranged in this order along the insertion direction of the mating housing 50. For this reason, even if an external force (load) from the counterpart housing 50 or the like acts on the inner housing 2, it can be absorbed by the elastic deformation of the seal member 10, and damage to the inner housing 2 can be reduced.
　また、インナーハウジング２とアウターハウジング２０との嵌合が完了すると、アウターハウジング２０の保持ロッド２３がインナーハウジング２のロッド挿入穴７に所定深さまで挿入される。ロッド挿入穴７に所定深さまで挿入された保持ロッド２３は、係止爪２３ａがロッド挿入穴７内に形成された係止凹部６１と係止される。これにより、インナーハウジング２は、アウターハウジング２０からの離脱が規制される。シール部材１０は、アウターハウジング２０と、アウターハウジング２０からの離脱が規制されたインナーハウジング２との間に所定の力で挟持される。 Further, when the fitting between the inner housing 2 and the outer housing 20 is completed, the holding rod 23 of the outer housing 20 is inserted into the rod insertion hole 7 of the inner housing 2 to a predetermined depth. The holding rod 23 inserted into the rod insertion hole 7 to a predetermined depth is locked with a locking recess 61 formed in the rod insertion hole 7 with a locking claw 23a. Thereby, the inner housing 2 is restricted from being detached from the outer housing 20. The seal member 10 is sandwiched with a predetermined force between the outer housing 20 and the inner housing 2 from which separation from the outer housing 20 is restricted.
　シール部材１０の位置決めや、インナーハウジング２の位置決めを行う保持ロッド２３に係止爪２３ａを設けることができる。即ち、アウターハウジング２０やインナーハウジング２を大型化することなく、コンパクトな構造でインナーハウジング２とアウターハウジング２０との係止構造を構築できる。 The locking claw 23a can be provided on the holding rod 23 for positioning the seal member 10 and positioning the inner housing 2. In other words, a locking structure between the inner housing 2 and the outer housing 20 can be constructed with a compact structure without increasing the size of the outer housing 20 or the inner housing 2.
　仮保持部１９が、保持ロッド２３（及び位置決めロッド５９）の外周に環状の座面（段部）として形成される。シール部材１０は、仮保持部１９に当接して、保持ロッド２３（及び位置決めロッド５９）に直角な姿勢で仮保持される。仮保持部１９が複数の保持ロッド２３（及び位置決めロッド５９）にそれぞれ形成されるので、シール部材１０は、インナーハウジング２によって押し込まれる際に、高精度に平行移動され得る。従って、シール部材１０を均一に圧縮させて、安定した水密性を得ることができる。また、保持ロッド２３（及び位置決めロッド５９）の突出方向を成形金型の離型方向に一致させることで、インナーハウジング２を容易に形成するとともに、仮保持部１９も容易に形成できる。 Temporary holding portion 19 is formed as an annular seating surface (step portion) on the outer periphery of holding rod 23 (and positioning rod 59). The seal member 10 contacts the temporary holding portion 19 and is temporarily held in a posture perpendicular to the holding rod 23 (and the positioning rod 59). Since the temporary holding portions 19 are respectively formed on the plurality of holding rods 23 (and the positioning rods 59), the seal member 10 can be translated in parallel with high accuracy when being pushed by the inner housing 2. Therefore, the seal member 10 can be uniformly compressed to obtain stable water tightness. Further, by making the protruding direction of the holding rod 23 (and the positioning rod 59) coincide with the mold release direction of the molding die, the inner housing 2 can be easily formed and the temporary holding portion 19 can be easily formed.
　さらに、インナーハウジング２とアウターハウジング２０の嵌合時に、アウターハウジング２０から突出された保持ロッド２３（及び位置決めロッド５９）の先端がロッド挿入穴７（４３）の開口縁７ａに突き当たることを防止できる。 Furthermore, when the inner housing 2 and the outer housing 20 are fitted together, the tip of the holding rod 23 (and the positioning rod 59) protruding from the outer housing 20 can be prevented from hitting the opening edge 7a of the rod insertion hole 7 (43). .
　なお、本実施形態では、保持ロッド２３が挿入されるロッド挿入穴７は、前方から見てショート端子収容室４の後方に設けられているが、それ以外の位置に設けられてもよい。ロッド挿入穴７の設置位置は制限されず、例えば、端子収容室３の一部をロッド挿入穴７に割り当ててもよい。また、本実施形態では、ショート端子収容室４が形成されたが、ショート端子収容室４は形成されなくてもよい。 In this embodiment, the rod insertion hole 7 into which the holding rod 23 is inserted is provided behind the short terminal accommodating chamber 4 when viewed from the front, but may be provided at other positions. The installation position of the rod insertion hole 7 is not limited. For example, a part of the terminal accommodating chamber 3 may be assigned to the rod insertion hole 7. Moreover, in this embodiment, although the short terminal accommodation chamber 4 was formed, the short terminal accommodation chamber 4 does not need to be formed.
　本実施形態では、保持ロッド２３は８本設けられたが、その本数は制限されない。保持ロッド２３の本数や寸法等は、インナーハウジング２の設置条件等によって決定される。本実施形態では、保持ロッド２３は、円柱形状を有している、種々の形状を有し得る。 In this embodiment, eight holding rods 23 are provided, but the number is not limited. The number and dimensions of the holding rods 23 are determined by the installation conditions of the inner housing 2 and the like. In the present embodiment, the holding rod 23 may have various shapes including a cylindrical shape.
　本実施形態の防水コネクタ１は、複数のメス端子５を収容するメスコネクタであったが、オス端子を収容するオスコネクタであってもよい。 The waterproof connector 1 of this embodiment is a female connector that accommodates a plurality of female terminals 5, but may be a male connector that accommodates male terminals.
　日本国特許出願第２０１３－１８３６５６号（２０１３年９月５日出願）及び日本国特許出願第２０１３－１９５７７７号（２０１３年９月２０日出願）の全ての内容は、ここに参照されることで本明細書に援用される。本発明の実施形態を参照することで上述のように本発明が説明されたが、本発明は上述した実施形態に限定されるものではない。本発明の範囲は、請求の範囲に照らして決定される。 The entire contents of Japanese Patent Application No. 2013-183656 (filed on September 5, 2013) and Japanese Patent Application No. 2013-195777 (filed on September 20, 2013) are referred to here.
