Description

【０００１】
【発明の属する技術分野】
本発明は、横長矩形状の挿入口にその挿入口を開閉するシャッターが装備されているシャッター付きコネクタを相手方コネクタとして用いるコネクタに関する。
【０００２】
【従来の技術】
実開平６−５０２７０号公報（第１先行例）に防塵対策を施した小形コネクタを相手方コネクタとして用いるプラグについての記載がある。このものは、相手方コネクタに差し込まれる突出部分にコンタクトを装備させ、突出部分で相手方コネクタに備わっているスライドを押し込んで上記コンタクトを相手方コネクタのコンタクトに接触させるようにしてある。
【０００３】
また、実登２６０１８００号公報（第２先行例）や実開平６−５４２６０号公報（第３先行例）には挿入口にシャッターを備えたコネクタを相手方コネクタとして用いるコネクタについての記載がある。このものは、相手方コネクタの挿入口に装備されているシャッターを、コネクタの突出部分により押し開きながらその突出部分を相手方コネクタに差し込むと、突出部分に設けられているコンタクトが相手方コネクタのコンタクトに接触するようになっている。
【０００４】
【発明が解決しようとする課題】
第１ないし第３の各先行例に記載されているコネクタは、いずれも、相手方コネクタに差し込まれている突出部分と、その突出部分を挟む両側に位置している相手方コネクタの内面との間に微小な隙間が確保されているに過ぎない。そのため、突出部分が相手方コネクタに差し込まれている状態でコネクタが無理にこじられたりすると、突出部分が相手方コネクタの内面に当たって突出部分が破損したり相手方コネクタのハウジングなどが破損したりするおそれがある。
本発明は以上の状況を改善するためになされたものであり、相手方コネクタに嵌合状に連結されたコネクタが無理にこじられても、相手方コネクタに差し込まれている部分や相手方コネクタが破損するおそれのないコネクタを提供することを目的とする。
【０００５】
また、本発明は、相手方コネクタに嵌合状に連結されたコネクタが無理にこじられたときには、当該コネクタが相手方コネクタから離脱して破損を未然に防ぐことのできるコネクタを提供することを目的とする。
【０００６】
【課題を解決するための手段】
図面を参照して本発明のコネクタを説明する。なお、この欄で図中の符号を使用したのは、発明の内容の理解を助けるためであって、内容を図例に限定する意図ではない。
【０００７】
本発明に係るコネクタＡは、横長形状のコネクタが相手方コネクタＢとして用いられ、その相手方コネクタＢには横長矩形状の挿入口５３が備わっている。しかも、本発明に係るコネクタＡは横長形状に形成されていて、相手方コネクタＢの挿入口５３からその内部空間Ｓに差し込まれることによりその相手方コネクタＢの内蔵電極６に接触される電極２３と、相手方コネクタＢに具備されている受け部５４ａに当接して上記内部空間Ｓに対する上記電極２３の差込代を規制する当り部１３ａと、上記電極２３の前側へ突き出された突出部３とを有していて、上記電極２３を上記挿入口５３から相手方コネクタＢの上記内部空間Ｓに差し込むときに相手方コネクタＢの上記挿入口５３を閉じているシャッター７を上記突出部３が押し開くようになっている。
【０００８】
本発明では、相手方コネクタＢの上記挿入口５３がこの相手方コネクタＢに具備されている相手方コネクタハウジング５の前端で開口されていて、上記受け部５４ａが上記挿入口５３の口縁部である相手方コネクタハウジング５の前端面５４によって形成されているのに対し、上記当り部１３ａが当該コネクタ（本発明に係るコネクタ）Ａのハウジング１の横長矩形状の前端面１３によって形成されていると共に、当該コネクタＡの厚さは相手コネクタＢのそれよりも厚くなっていて、上記受け部５４ａに上記当り部１３ａが当接している状態で当該コネクタＡが厚さ方向Ｔに沿う方向にこじられたときに、当該コネクタＡが、相手方コネクタハウジング５の前端面５４の厚さ方向片側の外側端縁５５ａ、あるいは、相手方コネクタハウジング５の前端面５４の厚さ方向他側の外側端縁５５ｂ、のいずれかを支点に傾動されるようになっており、
当該コネクタＡが厚さ方向Ｔに沿う方向にこじられることにより当該コネクタＡが傾動されるのに伴って、上記内部空間Ｓの周囲壁面の初期形状及び上記突出部３により押し開かれている上記シャッター７の初期形状を変形させることなく、上記突出部３が上記挿入口５３を経て上記内部空間Ｓの外側に抜け出るように、相手方コネクタハウジングの前端面の厚さ方向片側の外側端縁を中心としてその外側端縁から遠い側の上記挿入口の口縁に至る半径長さを持つ仮想円の内側に位置し、かつ、相手方コネクタハウジングの前端面の厚さ方向他側の外側端縁を中心としてその外側端縁から遠い側の上記挿入口の口縁に至る半径長さを持つ仮想円の内側に位置する先窄まり形状に形成されていると共に、その突出部３が上記挿入口５３を経て上記内部空間Ｓの外側に抜け出るときの移動軌跡の外側に相手方コネクタＢの上記内蔵電極６が配備されている。
【０００９】
この構成によると、当該コネクタＡが厚さ方向Ｔに沿う方向にこじられて傾動したとしても、相手方コネクタＢに挿入されている突出部３が相手方コネクタＢやそのシャッター７を破損させることなく抜け出るだけでなく、相手方コネクタＢの内蔵電極６を破損させるおそれがない。また、突出部３が破損するおそれもない。
【００１０】
そして、上記突出部３の外輪郭線Ｌの形状が、２つの上記仮想円Ｒ１，Ｒ２に沿う楕円類似形状になっていることが望ましい。
【００１１】
さらに、本発明では、当該コネクタＡの上記ハウジング１に接片部材２が内蔵され、その接片部材２の前端に凸円弧状に形成された上記電極２３が具備されていると共に、その電極２３が、当該コネクタＡの上記ハウジング１の前端面１３と上記突出部３の前端３１との相互間位置で上記突出部３の外輪郭線Ｌの外側に突き出ていると共に、上記相手方コネクタＢの上記内蔵電極６が、上記相手方コネクタハウジング５の内面に相手方コネクタの厚さ方向で重なり状に配備されていることが望ましい。
【００１２】
上記接片部材２が当該コネクタＡの厚さ方向Ｔに弾性変形可能であることが望ましい。
【００１３】
また、本発明では、上記受け部５４ａに上記当り部１３ａが当接したときに互いに係合し、かつ、上記受け部５４ａから上記当り部１３ａが離反されるのに伴って係合が解除される係合爪４２と係合面５１とが、上記相手方コネクタハウジング５と当該コネクタＡのハウジング１とに各別に備わっていると共に、当該コネクタＡが厚さ方向Ｔに沿う方向にこじられて傾動するときに、上記係合面５１との係合が解除された上記係合爪４２の移動軌跡が、上記係合面５１を挟む上記相手方コネクタハウジング５の厚さ方向で対向する両側壁に形成された盗み凹所５６の内側に位置するようになっていることが望ましい。
【００１４】
この場合、上記係合爪４２が、当該コネクタＡのハウジング１に具備された弾性撓み変形可能な杆部４１の先端に具備されていると共に、その係合爪４２に、上記盗み凹所５６の縁部５６ａと摺動してその縁部５６ａを乗り越える傾斜ガイド面４４が備わっていることが望ましい。
【００１５】
本発明に係るコネクタの作用は、以下に説明する実施形態を参照して明らかにする。
【００１６】
【発明の実施の形態】
図１は本発明に係るコネクタＡとその相手方コネクタＢとを個別に示した概略平面図、図２は図１のＩＩ−ＩＩ線に沿う部分を拡大して示した断面図、図３は相手方コネクタＢに連結したコネクタＡの概略平面図、図４〜図６は要部を拡大した縦断面図で示した作用説明図、図７は原理図、図８は係合爪・を拡大して示した概略平面図、図９は係合爪と係合面との係合状態を示した一部破断平面図、図１０は図９のＸ−Ｘ線に沿う部分を示した一部破断側面図である。
【００１７】
図１のように、コネクタＡは平面視横長矩形に形成されている。また、図１と図２を併せ見ることによって判るように、このコネクタＡでは、偏平な箱形に形成された中空のハウジング１によってその全体形状が定まっている。このハウジング１には、多数の溝１２が横方向等間隔おきに形成されていて、それらの各溝１２に接片部材２が配備されている。図２のように、この接片部材２は、その基部に幅広の取付部２１が一体に連設されていると共に、その取付部２１に支え杆部２２が一体に突出されていて、その支え杆部２２がハウジング１の内面に接触してバックアップされている。また、接片部材２はその前端２４がハウジング１の前端面１３の前側へ突き出ていると共に、この接片部材２は、コネクタＡの厚さ方向矢印Ｔに弾性変形可能であって、その前端２４には凸円弧状に形成された電極２３が備わっている。さらに、ハウジング１の前端面１３からその前方に向けて突出部３が一体に突設されている。この突出部３は、ハウジング１の前端面１３に横方向等間隔おきに設けられていて、相隣接する２つの突出部３，３の相互間に上記接片部材２４の先端２４や電極２３が位置している。そして、これらの突出部３の前端３１とハウジング１の前端面１３との相互間位置で上記電極２３がそれぞれの突出部３の外輪郭線の外側に突き出ている。したがって、電極２３は、突出部３の外輪郭線よりもハウジング１の厚さ方向Ｔの片側へ突き出ている。
【００１８】
図１のように、ハウジング１の横方向（幅方向）Ｗの両端部に係合片４が取り付けられている。この係合片４は、ハウジング１の前端面１３の前方へ突き出た弾性変形可能な杆部４１とその杆部４１に一体形成された係合爪４２とを備えている。
【００１９】
上記した突出部３や係合爪４２の具体的形状についてはさらに後述するものとする。
【００２０】
なお、上記したハウジング１は、溝１２を備えたハウジング本体１４と溝１２を塞ぐようにハウジング本体１４に結合されたカバー部１５とによって偏平な矩形箱形に形成されている。
【００２１】
次に、図１及び図２などを参照して相手方コネクタＢを説明する。相手方コネクタＢは、携帯端末機器としての携帯電話機に組み込まれてＩＯポートを形成させることなどに利用される。この相手方コネクタＢにおいて、偏平な横長中空のハウジング５（相手方コネクタハウジング）は、その左右の両端部に、上記したコネクタＡの係合爪４２に係合してそのコネクタＡの脱落を防ぐための係合面５１を備えている。また、図２のように、横方向等間隔おきに並んだ凹所５２を備え、これらの凹所５２のそれぞれに嵌め込まれた細長板状の内蔵電極６が、このハウジング５の内面に相手方コネクタＢの厚さ方向（上記ハウジング１の厚さ方向Ｔに一致する）で重なり状に配備されている。
【００２２】
ハウジング５の前端で挿入口５３が開口しており、この挿入口５３にシャッター７が装備されている。このシャッター７は、ハウジング５に内蔵されているばね体７１によって挿入口５３を閉じる方向に常時弾発付勢されていると共に、相手方コネクタＢの未使用時にはシャッター７が図示していない機構によって挿入口５３を閉じる位置に位置決めされている。また、このシャッター７は、上記したコネクタＡ側の電極２３を上記挿入口５３から内部空間Ｓに差し込むときに、突出部３によって押し開かれる。
【００２３】
ここまでで説明したコネクタＡを相手方コネクタＢに接続するときには、図４の矢印Ｙのように、コネクタＡの電極２３と突出部３とを相手方コネクタＢの挿入口５３からその内部空間Ｓに差し込む。これにより、上記挿入口５３を閉じていたシャッター７が突出部３により押し開かれてばね体７１の付勢に抗して後退し、電極２３が相手方コネクタＢの内蔵電極６に接触する。そして、電極２３の相手方コネクタＢの内部空間Ｓへの差込代は、ハウジング１の前端面１３がハウジング５の前端面５４に当接することによって規制される。したがって、互いに当接して電極２３の差込代を規制する当り部１３ａと受け部５４ａとが、それぞれ、ハウジング１の前端面１３と相手方コネクタＢの挿入口５３の口縁部であるハウジング５の前端面５４とによって形成されている。
【００２４】
図２で判るように、コネクタＡの厚さは相手方コネクタＢのそれよりも厚くなっている。そのため、図４のようにコネクタＡを相手方コネクタＢに接続したときには、コネクタＡのハウジング１の前端面１３である当り部１３ａに、相手方コネクタＢのハウジング５の前端面５４である受け部５４ａの全体が重なり状に当接する。そのため、コネクタＡの厚さ方向Ｔに沿う方向にこじり力が加わったときには、図５に示したように、コネクタＡが、相手方コネクタＢのハウジング５の前端面５４の厚さ方向片側の外側端縁５５ａの位置を支点として傾動するか、あるいは、図６に示したように、コネクタＡが、相手方コネクタＢのハウジング５の前端面５４の厚さ方向他側の外側端縁５５ｂの位置を支点として傾動するかのいずれかになる。そのため、コネクタＡがこじられて傾動するときの支点位置として、当該コネクタＡのハウジング１の前端面１３に当接している相手方コネクタＢのハウジング５の前端面５４の一方側の外側端縁５５ａの位置と他方側の外側端縁５５ｂの位置の２つの位置を想定することが可能である。そこで、このことを前提として、次に、上記した突出部３の形状について図７を参照しながら詳しく説明する。
【００２５】
すなわち、突出部３は、相手方コネクタＢのハウジング５の一方側の外側端縁５５ａの位置によって想定された一方側支点Ｐ１を中心としてその一方側支点位置から遠い側の挿入口５３の口縁５３ａに至る半径長さを持つ仮想円Ｒ１の内側に位置し、かつ、他方側端縁５５ｂの位置によって想定された他方側支点Ｐ２を中心としてその他方側支点位置から遠い側の上記挿入口の口縁５３ｂに至る半径長さを持つ仮想円Ｒ２の内側に位置するようにその形状が定められている。
【００２６】
突出部３の形状が図７で説明した形状に定められていると、図５に示したように、コネクタＡがこじられて、相手方コネクタＢのハウジング５の前端面５４の厚さ方向片側の外側端縁５５ａの位置を支点として傾動した場合、及び、図６に示したように、コネクタＡがこじられて、相手方コネクタＢのハウジング５の前端面５４の厚さ方向他側の外側端縁５５ｂの位置を支点として傾動した場合のいずれの場合でも、突出部３が、相手方コネクタＢの内部空間Ｓの周囲壁面すなわちハウジング５の内壁面やシャッター７を無理に押圧してそれらの初期形状を変形させてしまうという事態が起こらない。言い換えると、突出部３が、相手方コネクタＢの内部空間Ｓの周囲壁面の初期形状及びシャッター７の初期形状を変形させることなく、挿入口５３を経て内部空間Ｓの外側に抜け出るようになる。したがって、コネクタＡがこじられてたとしても、突出部３が破損したり、相手方コネクタＢのハウジング５が破損したりするおそれがない。
【００２７】
また、相手方コネクタＢの電極６は、上記したように、ハウジング５の内面に相手方コネクタＢの厚さ方向で重なり状に配備されているので、電極６の配備箇所は、突出部３が挿入口５３を経て内部空間Ｓの外側に抜け出るときの移動軌跡の外側に位置している。そのため、この電極６に突出部３が干渉して電極６又は突出部３が破損するという事態も起こりえない。
【００２８】
また、この実施形態では、図７に原理的に示してあるように、突出部３の外輪郭線Ｌの形状を、上記した２つの仮想円Ｒ１，Ｒ２の直近でそれらの仮想円Ｒ１，Ｒ２に沿う楕円類似形状にしてある。ここで、「突出部３の外輪郭線Ｌの形状が仮想円Ｒ１，Ｒ２に沿う楕円類似形状になっている」とは、突出部３の外輪郭線Ｌの形状が、突出部３の先端に近い位置ほど仮想円Ｒ１，Ｒ２に沿うように先窄まり形状になっているということである。このように突出部３の形状を定めておくと、ハウジング１の前端面１３からの突出部３の出幅Ｃが可及的長くなる。そのため、図４などに示した電極２３のハウジング１の前端面１３からの突出し長さを上記出幅Ｃに見合って長くすることが可能になるので、相手方コネクタＢの内蔵電極６における電極２３との接触範囲も長く形成することが可能になる。そして、内蔵電極６における電極２３との接触範囲を長くすると、それだけ内蔵電極６と電極２３との接触安定性ないし接触信頼性が向上するだけでなく、その電極２３を相手方コネクタＢの内部空間Ｓに対して挿抜するときの電極２３と内蔵電極６との擦れ幅が長くなってそれだけセルフクリーニング作用が向上するという利点がある。
【００２９】
図８〜図１０に示したように、上記した係合爪４２は、杆部４１の側方に突き出ていて、その周囲に傾斜ガイド面４４が具備されることによって先窄まり形状になっている。これに対し、相手方コネクタＢ側には、係合面５１を挟む上記相手方コネクタハウジング５の厚さ方向で対向する両側壁に盗み凹所（図１参照）が形成されている。そして、コネクタＡが厚さ方向Ｔに沿う方向にこじられて傾動するときに、係合面５１との係合が解除された係合爪４２の移動軌跡が、上記盗み凹所５６の内側に位置するようになっていると共に、上記傾斜ガイド面４４は、盗み凹所５６の縁部５６ａと摺動してその縁部５６ａを乗り越え得る勾配を有している。このため、コネクタＡが厚さ方向Ｔに沿う方向にこじられて傾動したときには、係合爪４２と係合面５１との係合が無理なく解除された後、係合爪４２が盗み凹所５６からその外側に抜け出る。したがって、コネクタＡと相手方コネクタＢとの連結が解除されてそれらの破損が未然に防止されるようになる。
【００３０】
図１０には、上記した一方側支点Ｐ１を中心としてその一方側支点位置から遠い側の盗み凹所５６の口縁５６ａに至る半径長さを持つ仮想円Ｒ３と、一方側支点Ｐ２を中心としてその他方側支点位置から遠い側の盗み凹所５６の口縁５６ｂに至る半径長さを持つ仮想円Ｒ４とをそれぞれ一点鎖線で示してあり、これらの仮想円Ｒ３，Ｒ４の内側に上記係合爪４２が位置するようにその係合爪４２の形状が定められている場合に、係合面５１との係合が解除された係合爪４２の移動軌跡が盗み凹所５６の内側に位置するようになる。
【００３１】
【発明の効果】
本発明によれば、相手方コネクタに連結されたコネクタが無理にこじられても、相手方コネクタに差し込まれている突出部や電極、相手方コネクタなどが破損するおそれがない。また、相手方コネクタに連結されたコネクタが無理にこじられたときには、当該コネクタが相手方コネクタから離脱して破損を未然に防ぐことができるようになる。

As shown in FIG. 2, the contact piece member 2 has a wide attachment portion 21 integrally connected to a base portion thereof, and a support collar portion 22 integrally protruding from the attachment portion 21, and the support member 21. The collar portion 22 is backed up in contact with the inner surface of the housing 1. In addition, the front end 24 of the contact piece member 2 protrudes to the front side of the front end face 13 of the housing 1, and the contact piece member 2 can be elastically deformed in the thickness direction arrow T of the connector A. 24 has an electrode 23 formed in a convex arc shape. Furthermore, the protrusion part 3 is integrally projected toward the front from the front end surface 13 of the housing 1. The protrusions 3 are provided on the front end surface 13 of the housing 1 at equal intervals in the lateral direction, and the tip 24 and the electrode 23 of the contact piece member 24 are interposed between the two adjacent protrusions 3 and 3. positioned. The electrodes 23 protrude outside the outer contour lines of the protrusions 3 at positions between the front ends 31 of the protrusions 3 and the front end surface 13 of the housing 1. Therefore, the electrode 23 protrudes to one side in the thickness direction T of the housing 1 from the outer contour line of the protrusion 3.
[0018]
As shown in FIG. 1, the engagement pieces 4 are attached to both end portions in the lateral direction (width direction) W of the housing 1. The engagement piece 4 includes an elastically deformable flange 41 protruding forward of the front end surface 13 of the housing 1 and an engagement claw 42 formed integrally with the flange 41.
[0019]
The specific shapes of the protruding portion 3 and the engaging claw 42 described above will be further described later.
[0020]
The housing 1 described above is formed in a flat rectangular box shape by a housing body 14 provided with the groove 12 and a cover portion 15 coupled to the housing body 14 so as to close the groove 12.
[0021]
Next, the mating connector B will be described with reference to FIGS. The counterpart connector B is used to form an IO port by being incorporated in a mobile phone as a mobile terminal device. In this mating connector B, the flat horizontally long hollow housing 5 (the mating connector housing) is engaged with the engaging claws 42 of the connector A at both left and right ends thereof to prevent the connector A from falling off. An engagement surface 51 is provided. Further, as shown in FIG. 2, the lateral regular intervals to comprise a recess 52 aligned, elongated plate-like internal electrode 6 fitted in each of these recesses 5 2, the other party to the inner surface of the housing 5 The connectors B are arranged in an overlapping manner in the thickness direction of the connector B (corresponding to the thickness direction T of the housing 1).
[0022]
An insertion port 53 is opened at the front end of the housing 5, and the shutter 7 is mounted on the insertion port 53. The shutter 7 is always urged and urged in a direction to close the insertion port 53 by a spring body 71 built in the housing 5, and the shutter 7 is inserted by a mechanism (not shown) when the counterpart connector B is not used. It is positioned at a position where the mouth 53 is closed. The shutter 7 is pushed open by the protruding portion 3 when the electrode 23 on the connector A side is inserted into the internal space S from the insertion port 53.
[0023]
When connecting the connector A described so far to the mating connector B, the electrode 23 and the protruding portion 3 of the connector A are inserted into the internal space S from the insertion port 53 of the mating connector B as indicated by an arrow Y in FIG. . As a result, the shutter 7 that has closed the insertion port 53 is pushed open by the projecting portion 3 and retracted against the bias of the spring body 71, and the electrode 23 contacts the built-in electrode 6 of the mating connector B. Then, the insertion allowance of the electrode 23 into the internal space S of the counterpart connector B is regulated by the front end face 13 of the housing 1 abutting against the front end face 54 of the housing 5. Therefore, the contact portion 13a and the receiving portion 54a that abut against each other and restrict the insertion allowance of the electrode 23 are the front end surface 13 of the housing 1 and the edge of the insertion port 53 of the mating connector B, respectively. The front end face 54 is formed.
[0024]
As can be seen from FIG. 2, the thickness of the connector A is thicker than that of the mating connector B. Therefore, when the connector A is connected to the mating connector B as shown in FIG. 4, the contact portion 13 a that is the front end surface 13 of the housing 1 of the connector A is connected to the receiving portion 54 a that is the front end surface 54 of the housing 5 of the mating connector B. The whole abuts in an overlapping manner. Therefore, when a twisting force is applied in the direction along the thickness direction T of the connector A, the connector A is connected to the outer end on one side in the thickness direction of the front end face 54 of the housing 5 of the mating connector B as shown in FIG. The connector A tilts with the position of the edge 55a as a fulcrum, or, as shown in FIG. 6, the connector A supports the position of the outer end edge 55b on the other side in the thickness direction of the front end face 54 of the housing 5 of the mating connector B. Can be either tilted as. Therefore, as a fulcrum position when the connector A is twisted and tilted, the outer end edge 55a on one side of the front end face 54 of the housing 5 of the mating connector B that is in contact with the front end face 13 of the housing 1 of the connector A is concerned. It is possible to assume two positions, the position and the position of the outer edge 55b on the other side. Therefore, on the premise of this, the shape of the protruding portion 3 will be described in detail with reference to FIG.
[0025]
That is, the protruding portion 3 has a lip 53a of the insertion port 53 on the side farther from the one fulcrum position around the one fulcrum P1 assumed by the position of the outer end edge 55a on the one side of the housing 5 of the mating connector B. The mouth of the insertion port located on the inner side of the virtual circle R1 having a radial length to reach and at the far side from the other side fulcrum position around the other side fulcrum P2 assumed by the position of the other side edge 55b The shape is determined so as to be located inside the virtual circle R2 having a radial length reaching the edge 53b.
[0026]
When the shape of the protruding portion 3 is set to the shape described in FIG. 7, the connector A is squeezed as shown in FIG. 5, and the one end in the thickness direction of the front end surface 54 of the housing 5 of the mating connector B is When tilted with the position of the outer edge 55a as a fulcrum, and as shown in FIG. 6, the connector A is twisted and the outer edge on the other side in the thickness direction of the front end surface 54 of the housing 5 of the mating connector B In any case of tilting with the position of 55b as a fulcrum, the projecting portion 3 forcibly presses the peripheral wall surface of the inner space S of the mating connector B, that is, the inner wall surface of the housing 5 and the shutter 7 to change their initial shapes. The situation of deforming does not occur. In other words, the protruding portion 3 comes out of the inner space S through the insertion port 53 without deforming the initial shape of the peripheral wall surface of the inner space S of the mating connector B and the initial shape of the shutter 7. Therefore, even if the connector A is twisted, there is no possibility that the protruding portion 3 is damaged or the housing 5 of the mating connector B is damaged.
[0027]
In addition, as described above, the electrode 6 of the mating connector B is disposed on the inner surface of the housing 5 so as to overlap in the thickness direction of the mating connector B. It is located outside the movement trajectory when exiting outside the internal space S via 53. Therefore, the situation that the protrusion 3 interferes with the electrode 6 and the electrode 6 or the protrusion 3 is damaged cannot occur.
[0028]
Further, in this embodiment, as shown in principle in FIG. 7, the shape of the outer contour line L of the projecting portion 3 is set to the virtual circles R1, R2 in the immediate vicinity of the two virtual circles R1, R2. The shape is similar to an ellipse. Here, “the shape of the outer contour line L of the protruding portion 3 is an ellipse-like shape along the virtual circles R 1 and R 2” means that the shape of the outer contour line L of the protruding portion 3 is the tip of the protruding portion 3. This means that the closer the position is to the tapered shape along the virtual circles R1 and R2. Thus, if the shape of the protrusion part 3 is defined, the protrusion width C of the protrusion part 3 from the front-end surface 13 of the housing 1 will become as long as possible. Therefore, the protruding length of the electrode 23 from the front end face 13 of the housing 1 shown in FIG. 4 and the like can be increased in accordance with the above-described protruding width C. Therefore, the electrode 23 in the built-in electrode 6 of the counterpart connector B It is possible to form a long contact range. When the contact range of the built-in electrode 6 with the electrode 23 is increased, not only the contact stability or contact reliability between the built-in electrode 6 and the electrode 23 is improved, but also the electrode 23 is connected to the internal space S of the mating connector B. There is an advantage that the width of rubbing between the electrode 23 and the built-in electrode 6 becomes longer and the self-cleaning action is improved accordingly.
[0029]
As shown in FIGS. 8 to 10, the engaging claw 42 protrudes to the side of the flange portion 41, and has a tapered shape by being provided with an inclined guide surface 44 around it. Yes. On the other hand, on the mating connector B side, a stealing recess (see FIG. 1) is formed on both side walls facing each other in the thickness direction of the mating connector housing 5 with the engagement surface 51 interposed therebetween. When the connector A is twisted and tilted in the direction along the thickness direction T, the movement trajectory of the engagement claw 42 released from the engagement surface 51 is located inside the stealing recess 56. Further, the inclined guide surface 44 has a slope that can slide over the edge 56a of the stealing recess 56 and ride over the edge 56a. For this reason, when the connector A is twisted and tilted in the direction along the thickness direction T, the engagement claw 42 and the engagement surface 51 are disengaged without difficulty, and then the engagement claw 42 is stolen. 56 exits outside of it. Therefore, the connection between the connector A and the mating connector B is released, and the breakage thereof is prevented.
[0030]
FIG. 10 shows a virtual circle R3 having a radius length from the one side fulcrum P1 to the mouth edge 56a of the stealing recess 56 on the side far from the one side fulcrum position, and one side fulcrum P2 as the center. A virtual circle R4 having a radial length extending from the other side fulcrum position to the mouth edge 56b of the stealing recess 56 on the far side is indicated by a one-dot chain line, and the engagement is carried out inside these virtual circles R3 and R4. When the shape of the engaging claw 42 is determined so that the claw 42 is positioned, the movement trajectory of the engaging claw 42 released from the engagement surface 51 is located inside the stealing recess 56. Will come to do.
