Description

【０００１】
【発明の属する技術分野】
本発明は、例えば自動車のワイヤハーネスに使用され、ハウジング同士の嵌合部にシール部材を介在させた防水コネクタに関するものである。
【０００２】
【従来の技術】
従来のこの種の防水コネクタは、電線を後部に接続した雌型の接続端子を収容した第１のハウジングと、電線を後部に接続した雄型の接続端子を収容した第２のハウジングとから成り、各ハウジングの後部は電線に嵌着したワイヤシール部材により防水され、ハウジング同士の嵌合部は第２のハウジングに装着したシール部材により防水されている。
【０００３】
【発明が解決しようとする課題】
しかしながら上述した防水コネクタでは、シール部材が雄型の接続端子を収容した第２のハウジングに装着されているので、ハウジング同士を嵌合する前には、第１のハウジングの嵌合部の前面が外部に露出し、損傷し易い状態になっている。このため、第１のハウジングの嵌合部の前面が損傷した場合に、シール部材との間に隙間が発生し、防水機能が損われるという問題がある。また、第１のハウジングの嵌合部の前面の外形は第２のハウジングの嵌合孔の間口よりも小さいので、ハウジング同士を嵌合する際に接続端子同士が整合しない場合が発生し、雄型の接続端子にこじれが生ずるという問題がある。
【０００４】
本発明の目的は、上述の問題点を解消し、ハウジングの損傷と接続端子のこじれを防止し得る防水コネクタを提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するための本発明に係る防水コネクタは、雌型の接続端子を収容した第１のハウジングと、前記雌型の接続端子と接続する雄型の接続端子を収容すると共に前記第１のハウジングと嵌合しその嵌合部にシール部材を備えた第２のハウジングとから成り、前記第１のハウジングは前端周囲に配置し前後動自在の筒状のスライダを備え、前記第２のハウジングは第１のハウジングとの嵌合時に前記スライダを覆うと共にその一部に当接して後方に移動させるフード部を備えた防水コネクタであって、前記第１のハウジングは、前記スライダの前記後方への移動に伴って変形し前記スライダを前方に付勢する弾性部材と、該弾性部材を押さえる押さえ部材と、該押さえ部材を前記ハウジング同士が完全に嵌合するまで係止する係止手段と、前記押さえ部材を前記ハウジング同士が完全に嵌合した後に解放し前記弾性部材の前記スライダに対する付勢力を解除する解除手段とを備え、前記第１、第２のハウジング同士が嵌合状態でないときの前記スライダの前端は前記弾性部材の付勢力により前記第１のハウジングの前面よりも前方に位置させたことを特徴とする。
【０００６】
【発明の実施の形態】

【０００７】
図２の分解斜視図にも示すように、コネクタ２のハウジング２１の前部外周面には、スライダ２２が前後動自在に設けられ、ハウジング２１の後部上面にはスライダ２２を前方に付勢する線細工ばね２３が前後動自在に配置されている。また、ハウジング２１の後部上面の線細工ばね２３の後方には、押さえ部材２４が前後動自在に配置され、この押さえ部材２４の上部にはカバー２５が覆設されている。そして、ハウジング２１の前部にはフロントホルダ２６が係合されている。
【０００８】
ハウジング２１の下部は端子収容部３１とされ、端子収容部３１の端子収容孔３２には、電線３３を後部に接続した雌型の接続端子３４がワイヤシール３５を介して収容され、係止アーム３６により端子収容孔３２から抜け出さないように係止されている。端子収容部３１の上壁外面には、係止突起３７ａを有し相手側のハウジング３のロック用突起１１と係合し得るロック用アーム３７が設けられている。端子収容部３１とロック用アーム３７の間には隙間が設けられており、スライダ２２の後述する押圧片が配置されている。そして、端子収容部３１の両側壁外面にはスライダ２２を案内する案内突条３８が設けられると共に、この案内突条３８の前部にはスライダ２２を係止しその前方への抜出しを防止する係止突起３８ａが設けられている。
【０００９】
端子収容部３１の後部の上壁外面には、線細工ばね２３の全部と押さえ部材２４の下部を前後動自在に収容する収容室３９が設けられている。この収容室３９は端子収容部３１の後面から突出されており、収容室３９の低壁には押さえ部材２４を案内するための中央の第１の案内溝４０と、一方の側壁側の第２の案内溝４１とが設けられている。また、ロック用アーム３７と収容室３９の間には、押さえ部材２４を係止するための係止部４２がブリッジ状に形成されている。そして、係止部４２の側部近傍には、カバー２５をヒンジ状に支持するために使用されるカバー用孔４３が形成され、収容室３９の側壁外面には、カバー２５をロックするために使用されるカバー用突起４４が形成されている。
【００１０】
スライダ２２は、ハウジング２１の端子収容部３１の外周に嵌合すると共に、ハウジング３のフード部５に嵌合する筒状部５１を有し、筒状部５１の上部にはハウジング２１のロック用アーム３７の下方に進入して線細工ばね２３を押圧する押圧片５２が形成されている。筒状部５１の前面には、ハウジング３のフード部５により押圧される２個の上部突片５３と１個の下部突片５４が設けられている。筒状部５１の両側壁外面には、溝５５ａを有してハウジング３の案内溝１２に進入し得る突条５５が設けられている。そして、筒状部５１の側壁内面には、ハウジング２１の案内突起３８を案内する案内溝５６と、ハウジング２１の係止突起３８ａを係止する係止溝５６ａが設けられている。
【００１１】
線細工ばね２３はスライダ２２の押圧片５２により押圧される円弧状部２３ａと、この円弧状部２３ａの両端から相互に縮径するように延在する左右の縮径部２３ｂとを有し、ハウジング２１の軸線に対称な形状とされている。また、線細工ばね２３はハウジング２１の収容室３９内に円弧状部２３ａを前方に向けて前後動自在に収容され、縮径部２３ｂは押さえ部材２４により案内されるようになっている。押さえ部材２４はハウジング２１の収容室３９に前後動自在に収容される摺動板６１を有し、この摺動板６１の上面には手指等により押圧される押圧突起６２が設けられ、この押圧突起６２の前面には可撓片６３が前向きに設けられている。
【００１２】
図３は図１のＡ−Ａ線に沿って切断した断面図であり、摺動板６１の下面には、線細工ばね２３の縮径部２３ｂを後方に移動した際に拡径するように案内する案内部６４が形成されている。また、摺動板６１の下面にはハウジング２１の第１の案内溝４０と第２の案内溝４１にそれぞれ嵌合する案内突起６５、６６が設けられている。可撓片６３の前部上面には、ハウジング２１の係止部４２に係止される係止突起６７が設けられている。この係止突起６７の垂直な後面６７ａは、ハウジング２１の係止部４２の前面に係合され、係止突起６７の傾斜した前面６７ｂは相手側のハウジング３のロック用突起１１により下方に押圧されるようになっている。
【００１３】
そして、カバー２５はハウジング２１の収容室３９を覆う覆板７１を有し、覆板７１の中央には押さえ部材２４の押圧突起６２を前後方向に案内する案内窓７２が形成されている。覆板７１の前部にはハウジング２１のカバー用孔４３に係合される２個のヒンジ用突起７３が設けられ、覆板７１の左右の外面には、ハウジング２１のカバー用突起４４に係合するロック用枠７４が形成されている。
【００１４】
ここで、コネクタ１と嵌合しないコネクタ２の初期状態では、押さえ部材２４の係止突起６７は係止部４２に係止され、線細工ばね２３の後部は押さえ部材２４の案内部６４の前部に位置付けられている。また、スライダ２２の押圧片５２はロック用アーム３７の下側を通って線細工ばね２３に当接され、スライダ２２の前面はハウジング２１の前面よりも前方に位置している。この際に、ハウジング２１の係止突起３８ａがスライダ２２の係止溝５６ａに係合することにより、スライダ２２はハウジング２１から前方に抜け出さないように係止されている。
【００１５】
そして、接続端子８、ハウジング２１、スライダ２２、線細工ばね２３、押さえ部材２４、カバー２５、接続端子３４等は、コネクタ１とコネクタ２を嵌合する際に次のように作用するように形成されている。
【００１６】
(1) 図４、図５に示すように、初期状態にあるコネクタ２にコネクタ１を嵌合すると、ハウジング３のフード部５がスライダ２２の外側を進入し、フード部５の前面５ａがスライダ２２の上下の突片５３、５４に当接する。
【００１７】
(2) コネクタ１、２を更に嵌合すると、図６、図７に示すようにハウジング３がスライダ２２を後方に移動させると共に、ロック用突起１１がロック用アーム３７を下方に撓ます。このとき、押さえ部材２４の係止突起６７が係止部４２に係止されているので、線細工ばね２３はスライダ２２の押圧片５２により押圧され後方に駆動される。また、接続端子８、３４同士の接触圧が増加する。そして、線細工ばね２３の縮径部２３ｂが押さえ部材２４の案内部６４により拡径するように案内され、線細工ばね２３に弾発力が蓄積される。
【００１８】
従って、この状態でコネクタ１、２に加える力を弱めると、線細工ばね２３の縮径部２３ｂが縮径するように作用し、線細工ばね２３が逆戻りする。これにより、線細工ばね２３がスライダ２２を介してハウジング３を押し戻し、コネクタ１、２の不完全嵌合状態を明確にする。
【００１９】
(3) そして、コネクタ１、２を最終的に嵌合すると、図８、図９に示すようにロック用突起１１がロック用アーム３７の係止突起３７ａを乗り越え、ロック用アーム３７が復元してロック用突起１１と係合する。このとき、接続端子８、３４同士は十分に接続する。同時に、ロック用突起１１が押さえ部材２４の係止突起６７の前面６７ｂを下方に押圧し、係止突起６７を係止部４２から外す。これにより、押さえ部材２４と線細工ばね２３が自由状態となり、図１０、図１１に示すように押さえ部材２４は線細工ばね２３の弾発力により最後方に駆動され、コネクタ１、２は線細工ばね２３により付勢されることなく完全に嵌合する。なお、コネクタ２を初期状態に戻すためには、押さえ部材２４を方向Ｂに押し込めばよい。
【００２０】
このように、実施例ではコネクタ１、２が嵌合しない状態において、スライダ２２の前面がハウジング２１の前面よりも前方に位置するようにスライダ２２をハウジング２１に係止したので、ハウジング２１の前面をスライダ２２によって保護することが可能となる。従って、ハウジング２１の前面の損傷を防止でき、コネクタ１、２同士を嵌合した際の防水機能を良好に保持できる。また、ハウジング２１の外周に嵌着したスライダ２２がハウジング３のフード部５に嵌合するので、コネクタ２の嵌合部の外形がコネクタ１の間口と同等となり、接続端子８、３４同士が良好に整合し、接続端子８の接続端８ａのこじりを防止することができる。
【００２１】
なお、ハウジング３１と押さえ部材２４を係止部４２を介して係止し、ハウジング３のロック用突起１１の作用により係止を解除するようにしたが、押さえ部材２４をロック用アーム３７の一部で係止し、ロック用アーム３７が撓んだ際に押さえ部材とロック用アームの一部の係止を解除するようにしてもよい。また、押さえ部材２４をハウジング３１の一部で仮係止し、押さえ部材２４に所定以上の力が加わったときに、押さえ部材２４とハウジング３１の一部の係止を解除するようにすることもできる。
【００２２】
【発明の効果】
以上説明したように本発明に係る防水コネクタでは、第２のハウジングが作用しないときのスライダの前面を第１のハウジングの前面よりも前方に位置させたので、第１のハウジングの前面をスライダにより保護することができ、その損傷を防止でき、ハウジング同士が嵌合した際の防水機能を良好に維持できる。また、スライダを第１のハウジングの外周に嵌合したので、スライダの外形が第２のハウジングの間口と同等となり、ハウジング同士や接続端子同士が整合し易くなり、雄型の接続端子のこじりを防止できる。

A matching lock frame 74 is formed.
[0014]
Here, in the initial state of the connector 2 that does not fit into the connector 1, the locking protrusion 67 of the pressing member 24 is locked to the locking portion 42, and the rear portion of the wirework spring 23 is in front of the guide portion 64 of the pressing member 24. Is positioned in the department. Further, the pressing piece 52 of the slider 22 passes through the lower side of the locking arm 37 and comes into contact with the wirework spring 23, and the front surface of the slider 22 is positioned forward of the front surface of the housing 21. At this time, the locking projection 38 a of the housing 21 is engaged with the locking groove 56 a of the slider 22, so that the slider 22 is locked so as not to come out of the housing 21 forward.
[0015]
The connection terminal 8, the housing 21, the slider 22, the wirework spring 23, the pressing member 24, the cover 25, the connection terminal 34, etc. are formed so as to act as follows when the connector 1 and the connector 2 are fitted. Has been.
[0016]
(1) As shown in FIGS. 4 and 5, when the connector 1 is fitted to the connector 2 in the initial state, the hood portion 5 of the housing 3 enters the outside of the slider 22, and the front surface 5a of the hood portion 5 is the slider. 22 abuts on the upper and lower protrusions 53, 54.
[0017]
(2) When the connectors 1 and 2 are further fitted, the housing 3 moves the slider 22 backward as shown in FIGS. 6 and 7, and the locking projection 11 bends the locking arm 37 downward. At this time, since the locking protrusion 67 of the pressing member 24 is locked to the locking portion 42, the wirework spring 23 is pressed by the pressing piece 52 of the slider 22 and driven backward. Further, the contact pressure between the connection terminals 8 and 34 increases. Then, the diameter-reduced portion 23 b of the wire-working spring 23 is guided by the guide portion 64 of the holding member 24 so that the diameter thereof is expanded, and the elastic force is accumulated in the wire-working spring 23.
[0018]
Therefore, if the force applied to the connectors 1 and 2 is weakened in this state, the diameter-reduced portion 23b of the wire-working spring 23 acts so as to reduce the diameter, and the wire-working spring 23 returns. As a result, the wirework spring 23 pushes back the housing 3 via the slider 22 to clarify the incompletely fitted state of the connectors 1 and 2.
[0019]
(3) When the connectors 1 and 2 are finally fitted, the locking projection 11 gets over the locking projection 37a of the locking arm 37 as shown in FIGS. 8 and 9, and the locking arm 37 is restored. Engage with the locking projection 11. At this time, the connection terminals 8 and 34 are sufficiently connected. At the same time, the locking projection 11 presses the front surface 67 b of the locking projection 67 of the pressing member 24 downward, and removes the locking projection 67 from the locking portion 42. As a result, the holding member 24 and the wire work spring 23 are brought into a free state, and as shown in FIGS. 10 and 11, the holding member 24 is driven to the rear by the elastic force of the wire work spring 23, and the connectors 1 and 2 are It fits completely without being urged by the craft spring 23. In order to return the connector 2 to the initial state, the pressing member 24 may be pushed in the direction B.

In this way, in the embodiment, in a state where the connectors 1 and 2 are not fitted, the slider 22 is locked to the housing 21 so that the front surface of the slider 22 is positioned forward of the front surface of the housing 21. Can be protected by the slider 22. Therefore, the front surface of the housing 21 can be prevented from being damaged, and the waterproof function when the connectors 1 and 2 are fitted can be satisfactorily maintained. Moreover, since the slider 22 fitted to the outer periphery of the housing 21 is fitted to the hood portion 5 of the housing 3, the outer shape of the fitting portion of the connector 2 is equivalent to the opening of the connector 1, and the connection terminals 8 and 34 are good.
