现在，将参照附图更详细地描述根据本申请的示例性实施例。

第一优选实施方式
本申请的第一优选实施方式提供一种光纤连接器110，图1至图10示意性地示出了该光纤连接器110。该光纤连接器110用于与光纤适配器160对接，例如与本申请中第二优选实施方式的光纤适配器160或第四优选实施方式的光纤适配器260对接，以组成光纤连接系统，例如组成本申请第三优选实施方式中的光纤连接系统100或第五优选实施方式中的光纤连接系统200。
参考图1和图2，其示意性地示出本申请第一优选实施方式的光纤连接器110。从图2中，依次可以看到外壳体135、内壳体111、插芯组件121、弹性件133、密封部134、后主体122、光缆140、压接环141和尾套142。其中，内壳体135、外壳体111和插芯组件121位于光纤连接器110的近端，用于与光纤适配器连接。
在下面的描述中，连接器的近端用以描述连接器与适配器连接的一端，远端用以描述连接器的光缆端。此外，以图9为例，从远端向近端延伸的 方向称为向前方向(即图9中的D1方向)，从近端向远端延伸的方向称为向后方向(即图9中的D2方向)，插芯组件中光纤排列的方向(即图9中的上下方向)称为光纤连接器的纵向，同时与前后方向和纵向正交的方向(即图9中垂直纸面的方向)称为光纤连接器的横向。
参考图1、图2、图3和图10，内壳体111包括前端部分112、中部部分114和后端部分113，其中形成开放空间115。中部部分114连接在前端部分112和后端部分113之间。开放空间115从前端部分112贯通延伸至后端部分113。前端部分112用于插入光纤适配器160中。如图1和图3所示，前端部分112沿纵向延伸的两个侧面大致为平面，其中一个侧面上设置有极性键118。前端部分112沿横向延伸的两个侧面平坦略有弧度，其上在两侧可以设置沿前后方向延伸的凸起，在较靠后的部分设置第三卡接部119(下文描述)。后端部分113用于接收后主体122。后端部分113在其沿横向延伸的侧面上可以设置有第一卡接部116(下文描述)。中部部分114上优选设置有第二卡接部117(下文描述)。优选地，该内壳体111形成为一整体构件。
插芯组件121设置在内壳体111的开放空间115中。插芯组件121用于连接及容纳光纤，例如从光缆140中伸出的光纤。并且，插芯组件121至少部分地从前端部分112露出。
参考图4、图9和图10，后主体122包括插入部分123、过渡部分125和露出部分124，其中形成光纤通道126。其中，过渡部分125连接于插入部分123和露出部分124之间。露出部分124用于接收光纤，其可以构造成如图所示的类圆柱形。光纤通道126从露出部分124贯通延伸至插入部分123，并与开放空间115连通。插入部分123至少部分地沿向前方向D1插入后端部分113中，过渡部分125与内壳体111的后端部分113附接。优选地，过渡部分125的沿垂直于向前方向D1的截面尺寸大于插入部分123的截面尺寸，以使得过渡部分125能够与后端部分113抵接。且过渡部分125的沿横向延伸的两个侧面优选设置凸耳145，例如半圆形或扇形的凸耳145，由此更便于与后端部分113抵接。后主体122具有第一配合部129，且第一配合部129构造为与第一卡接部116形成卡合。
如图3所示，内壳体111的后端部分113的沿垂直于向前方向D1的内部截面尺寸大于中部部分114的内部截面尺寸，由此在此处形成台阶结构。换句话说，开放空间115可以形成为台阶孔。当插入部分123由后端 部分113插入后，插入部分123抵接至中部部分114的后端。换言之，参考图9，插入部分123抵接在上述台阶孔的台阶上。
弹性件133设置于开放空间115并位于插芯组件121和后主体122之间，且后主体122构造为将弹性件133挤压在插芯组件121上。具体而言，插入部分123的朝向向前方向D1的表面设置有容纳部143，弹性件133位于容纳部143中。并且该弹性件133构造为挤压后主体122使得后主体122倾向于朝向向后方向D2移动，以使得第一卡接部116和第一配合部129能够卡紧。同时，该弹性件133构造为挤压插芯组件121，使其能够相对固定于内壳体111的前端部分112，从而使其相对固定在光纤连接器110的近端。
密封部134布置在内壳体111和后主体122之间并抵接于插入部分123，且后主体122构造为将密封部134挤压在内壳体111上。例如，后主体122的插入部分123和内壳体111的中部部分114夹住该密封部134。在图示实施方式中，后主体122的插入部分123将密封部134压紧在上述开放空间115形成的台阶孔的台阶上。
根据本实施例的光纤连接器110，利用卡接结构实现后主体122和内壳体111之间的连接，不但便于装配，还能避免光纤出现位移，例如避免出现光纤因后主体和内壳体之间的螺纹安装出现位移而导致的断裂损坏现象。并且，还通过设置密封部134实现防水功能，可以避免液体通过连接器进入设备内部。
参考图3、图4和图9，第一卡接部116可以构造为开设于内壳体111的后端部分113的沿横向延伸的侧面上的开口。第一配合部129设置于与插入部分123，第一配合部129可以具有凸出部132，由此其能够和开口形式的第一卡接部116实现卡接。第一配合部129具有第一端130和与第一端130相反的第二端131，其中第二端131比第一端130更靠近光纤连接器110的远端。第一端130与插入部分123连接，第二端131与插入部分123的外表面隔开，上述凸出部132布置于第二端131处，例如凸出部132在第二端131沿远离插入部分123的方向凸出。其中，第一配合部129能够通过变形使第二端131抵近插入部分123的外表面，以使得凸出部132能够进入开口形成卡合。示例性地，当将后主体122插入内壳体111的过程中时，后主体122上的第一配合部129的凸出部132首先与内壳体111的后端部分113接触，从而第一配合部129在后端部分113的挤压下变形， 使得凸出部132能够进入后端部分113内，当凸出部132移动到开口处时，第一配合部129恢复变形实现凸出部132与开口的卡接。
参考图1、图4和图10，后主体122的过渡部分125还具有键部分127，该键部分127位于后主体122的沿纵向延伸的两个侧面。键部分127朝向向前方向D1延伸，且键部分127与插入部分123间隔开，以使得内壳体111的后端部分113能够被夹在键部分127和插入部分123之间，由此进一步提高连接的稳定性。优选地，键部分127的侧表面(沿纵向方向延伸的侧面)设置有凹凸结构128，键部分127用于插入光纤适配器160上的键槽口168中，且凹凸结构128能够与键槽口168的侧壁上的附加凹凸结构169形成配合连接。以限制光纤连接器110的晃动并防止出现响声。
参考图1、图2、图5和图9，光纤连接器110还包括外壳体135，外壳体135包括框架部136和连接于框架部136的操作部137。示例性地，框架部136可以构造成中空的类似框状，或者彼此相对且间隔设置的两个梁。操作部137设置于框架部136的沿纵向相对设置的两个侧面上，并从框架部136沿向后方向D2延伸。操作部137用于被操作人员持有操作，其外部表面可以选择设置防滑纹。框架部136设置有第二配合部138，外壳体135沿向后方向D2套设于内壳体111。相对应的，内壳体111的中部部分114上设置有第二卡接部117，且第二卡接部117与第二配合部138能够形成卡合。第二卡接部117优选设置在沿纵向延伸的侧面上，例如，在一个侧面上位于极性键118的后方。
可选地，第二卡接部117构造为凸出于内壳体111的外表面的凸起部117，第二配合部138构造为框架部136的沿向前方向D1的端部，其中第二卡接部117与第二配合部138形成卡合时框架部136位于凸起部117的后方。
内壳体111的后端部分113设置有阻挡部120。示例性地，内壳体111的后端部分113的沿垂直于向前方向D1的外部截面尺寸大于中部部分114的外部截面尺寸，由此在内壳体111外部也台阶结构，该台阶则形成上述阻挡部120。外壳体135的框架部136具有弹性部139，弹性部139与阻挡部120抵接，以使得外壳体135倾向于朝向向前方向D1移动而使第二卡接部117和第二配合部138卡紧。图示实施方式中，弹性部139可以是朝向向后方向D2倾斜延伸且可变形的弹性臂。
此外，如图3和图9所示，前端部分112上还设置有第三卡接部119， 以用于和光纤适配器160的卡钩元件171的钩部185相配合，以在光纤连接器110插入光纤适配器160后能够被固定。第三卡接部119优选为沿横向方向延伸的凸起，截面呈梯形，以便于对光纤适配器的卡钩元件171上的钩部185进行导向。由此，第三卡接部119也可以称为倾斜部119，该倾斜部119与中部部分114之间的槽形成锁定凹槽。进而，倾斜部119与锁定凹槽共同形成卡合结构，使得卡钩元件171上的钩部185进入锁定凹槽中形成卡接。
图6、图7和图8示出了光纤连接器110的装配过程。其中第一步装配参考图6，首先将内壳体111、插芯组件121、弹性件133、密封部134和后主体122装配在一起。安装方向可以是将内壳体111沿向后方向D2卡接至后主体122，或者将后主体122沿向前方向D1卡接至内壳体111。
第二步装配参考图7，将外壳体135沿向后方向D2套设至内壳体111之外，使得框架部136位于凸起部117的后方，并且框架部136的弹性部139与更后方的阻挡部120抵接，使得外壳体135的位置被凸起部117和阻挡部120限定。
第三步装配参考图8，将光缆140连接至后主体122的露出部分124，并将光缆140中的光纤经由光纤通道126连接至插芯组件121。之后将压接环141连接至露出部分124，通过螺纹连接的旋转作用，并利用压接环141内表面的固定齿，将光纤压紧。然后，将尾套142套设在露出部分124上，该尾套142可以为热收缩管，利用尾套142的加热收缩将光缆140、压接环141和后主体122紧固在一起。
第二优选实施方式
本申请的第二优选实施方式提供一种光纤适配器160，图11至图14示出了该光纤适配器160。在本实施方式中，光纤适配器的纵向与第一实施方式中光纤连接器的纵向相同，在图14中为垂直于直面的方向。光纤适配器的横向与第一实施方式中光纤连接器的横向相同，在图14中为上下方向。
本申请的第二优选实施方式的光纤适配器160包括两个相反设置的接收部和位于两个接收部之间的分隔壁163。例如，本实施方式中光纤适配器160包括第一接收部161、第二接收部162和连接在第一接收部161和第二接收部162之间的分隔壁163。
其中，第一接收部161用于接收第一光纤连接器110，第一光纤连接器110可以是上述第一优选实施方式中的光纤连接器110。第二接收部162用于接收第二光纤连接器10，第二光纤连接器10可以是不同于上述第一优选实施方式的光纤连接器，例如标准光纤连接器。
参考图11、图12和图14，第一接收部161包括第一壳体164、第一密封件170和卡钩元件171。其中，第一壳体164具有第一插入端165、第一对接端166以及从第一插入端165贯通延伸至第一对接端166的第一通路167。第一插入端165用于第一光纤连接器110的插入，第一对接端166用于与第二光纤连接器10的对接。第一密封件170设置于第一对接端166，并附接于分隔壁163上。卡钩元件171设置于第一壳体164中，并构造为将第一密封件170挤压至分隔壁163，卡钩元件171具有容纳至少部分光纤连接器110的容纳空间181。
第二接收部162相对于第一接收部161相反设置，第二接收部162包括第二壳体172和另外的卡钩元件171。其中第二壳体172具有第二插入端173、第二对接端174以及从第二插入端173贯通延伸至第二对接端174的第二通路175，第二通路175在分隔壁163处于第一通路167相连通。例如，分隔壁163上可以设置通孔(也可称分隔壁通孔)，第二通路175经由该分隔壁通孔与第一通路167相连通。并且，上述第一密封件170围绕该通孔附接在分隔壁163上。第二插入端173用于第二光纤连接器10的插入，第二对接端174用于与第一光纤连接器110的对接。另外的卡钩元件171设置在第二壳体172中，其具有与第一接收部161中的卡钩元件171相同的结构。
示例性地，参考图13，第一接收部161和第二接收部162中的卡钩元件171包括卡钩主体177、侧臂178、锁定部179和极性部180。卡钩主体177的内部形成容纳空间181，以用于容纳光纤连接器的部分结构。该容纳空间181，贯通卡钩元件171，其可以视为构成第一通路167或第二通路175的一部分。侧臂178连接至卡钩主体177的沿纵向相对的两个侧面，侧臂178被构造为当光纤连接器110插入光纤适配器160时卡锁光纤连接器110。例如，侧臂178端部的钩部185与光纤连接器110的内壳体111侧面的第三卡接部119实现卡接。锁定部179设置于卡钩主体177的外表面，例如卡钩主体177的沿横向相对设置的两个侧面。该侧面可以是平坦表面，锁定部179从该平坦表面向外凸出。锁定部179构造为能够使卡钩 元件171连接至接收部的壳体。示例性地，接收部的壳体的沿横向相对的两个外侧面设置有卡槽(也可称配合窗)，卡钩主体177上的锁定部179能够与该卡槽或配合窗形成卡合。极性部180设置于卡钩主体177的内表面，例如极性部180可以沿横向相对设置的两个内表面中的一个上。极性部180用于接收光纤连接器110上的极性键118。在图示实施方式中，极性部180构造为在卡钩主体177的内表面凹陷的极性槽180。
优选地，第一接收部161和第二接收部162中的两个卡钩元件171各自的极性部180的取向相反。在本实施方式中，第一接收部161中的卡钩元件171的内表面构造为与第一光纤连接器110的内壳体111的前端部分112的外侧表面紧密贴合，以提高插入的稳定性，从而减少防水失效的可能，进而提高防水密封的性能。优选地，第一壳体164的第一插入端165设置有键槽口168，该键槽口168位于，第一壳体164的沿横向相对设置的两个侧面上。键槽口168用于接收第一光纤连接器110的键部分127。键槽口168的周缘设置有附加凹凸结构169，以能够和第一光纤连接器110的键部分127上的凹凸结构128相配合，从而限制第一光纤连接器110的晃动并防止出现响声(参考图17)。其中，附加凹凸结构169和凹凸结构128中的一者是凸起，另一者是凹陷，反之亦可。由此，此二者也能实现卡合，从而进一步防止光纤连接器110沿向前方向D1和向后方向D2上的晃动，防止出现因前后晃动导致的防水密封失效。
并且，第一壳体164的第一插入端165优选沿远离分隔壁163的方向延伸，以能够包围第一光纤连接器110的内壳体111的中部部分114。由此，能够进一步降低第一光纤连接器110上下晃动和左右晃动出现的可能，进一步提高连接稳定性，避免出现防水密封失效。
优选地，本实施方式中光纤适配器160还包括挡壁186(也可称安装部186)和第二密封件176。挡壁186围绕第一接收部161设置在第一接收部161和第二接收部162的接合处，挡壁186的面向第二接收部162的侧面设置有接收槽。第二密封件176围绕第二接收部162设置，并附接于接收槽内。
本实施方式的光纤适配器160可以用于设备的光纤对接，例如本实施方式的光纤适配器160设置在设备上，挡壁186利用紧固件183和垫圈184固定在设备上，第二密封件176位于挡壁186与设备的外表面之间，防止水从光纤适配器160与设备外壳的连接处进入设备内部。

本实施方式的光纤连接系统100可以用于光缆与设备之间的连接。例如，外部光缆与第一光纤连接器110连接，设备的光缆与第二光纤连接器10连接。
第一光纤连接器110和第二光纤连接器10分别被推入光纤适配器160的第一接收部161和第二接收部162中。第一光纤连接器110挤压第一接收部161中的第一密封件170，以实现外部环境与光纤连接系统100之间的密封。并且，光纤适配器160通过紧固件183和垫圈184连接至设备外壳，以压紧第二密封件176，实现外部环形与设备之间的密封。
第四优选实施方式
本申请的第四优选实施方式提供一种光纤适配器260，图19至图20示出了该光纤适配器260。
本申请的第四优选实施方式的光纤适配器260是第二优选实施方式的光纤适配器160的变形。因此，具有与第二优选实施方式中的功能基本相同的功能的元件将在此进行相同的编号，并且为了简洁起见将不再对其进行详细描述和/或图示。
本申请第四优选实施方式中的光纤适配器260与第二优选实施方式的区别在于，光纤适配器260包括两个相反设置的第一接收部161和位于两个第一接收部161之间的分隔壁163。两个第一接收部161的两个第一密封件170彼此相对地附接于分隔壁163，且两个第一接收部161的两个第一通路167在分隔壁163处相连通。
本申请第四优选实施方式中的光纤适配器260不具有第二优选实施方式中的挡壁186和第二密封件176。并且，两个第一接收部161的两个卡 钩元件171各自的极性部180的取向相反。
第五优选实施方式
本申请的第五优选实施方式提供一种光纤连接系统200，图21至图23示出了该光纤连接系统200。
本申请的第五优选实施方式的光纤连接系统200包括第四优选实施方式中的光纤适配器260以及两个本申请第一优选实施方式中的光纤连接器110。
本实施方式中的光纤连接系统200，可以用于光缆与光缆之间的连接。例如两个光缆分别与两个第一光纤连接器110连接。两个第一光纤连接器110分别被推入光纤适配器260的两个第一接收部161中。两个接收部中的两个第一密封件170，分别被一个第一光纤连接器110压紧，由此实现外部环境与光纤连接系统200之间的密封。
根据本申请的光纤连接系统，通过在连接器和适配器内分别设置防水部件，当连接器连接至适配器时，连接器的内壳体在前后端分别抵靠防水部件，使得设备与外部环境的连接开口处均有防水部件密封，有效地防止水分进入设备内部。
第六优选实施方式
本申请的第六优选实施方式提供一种光纤连接器11，图24、图27-图31以及图37-39示出了该光纤连接器11。在本实施方式中，轴向为与光纤延伸的方向平行的方向，轴向方向也称为前后方向，横截面为垂直于轴向方向的截面。
在图24中，光纤连接器11包括外壳体20、内壳体30、后柱体50(也可称后主体50)和尾套65。外壳体20可围绕内壳体30设置，内壳体30内设置有套箍40(也可称插芯组件40)并且套箍40从内壳体30的一端露出。套箍40包括多个光纤。
在图27中，光纤连接器11还包括弹簧45(也可称弹性件45)，弹簧45的一端抵靠套箍40，另一端抵靠抵止件46，从而使得套箍40能够在受到压力后在内壳体30内移动并在压力移除后回复到初始位置。连接器垫圈49(也可称密封部49)设置在内壳体30与后柱体50之间，内壳体30与 后柱体50可通过螺纹连接，并在连接时挤压连接器垫圈49，进而防止水分及杂质等进入连接器内部。光缆55通过卡环60(也可称之为压接环60)与后柱体50连接。尾套65套设在光缆55的外周。
如图28所示，外壳体20包括用于容纳内壳体30的内部空间21。内部空间21中设置有沿轴向延伸的槽23，槽23可引导内壳体30插入外壳体20中。槽23包括突出部22，突出部22可将外壳体20限定在预定位置，并防止外壳体20脱离内壳体30。内壳体30从外壳体20的一端伸出，外壳体20的与之相对的一端设置有柔性臂25(也可称为弹性部25)。柔性臂25可从外壳体20的主体向外延伸并具有弹性回复力，如图所示，外壳体20包括两个向不同方向延伸的柔性臂25。
在图29中，内壳体30包括容置空间31(也可称开放空间31)，套箍40被布置在容置空间31中并从容置空间31伸出。内壳体30包括前端38(也可称为前端部分)和后端39(也可称为后端部分)。内壳体30在前端38附近设置键部32(也可称极性键32)。后端39包括外螺纹部33，后端39还设置有阻挡部37，柔性臂25可抵靠阻挡部37，由此防止内壳体30与外壳体20分离。内壳体30包括位于两侧的卡合结构35，卡合结构35包括锁定凹槽35a和倾斜部35b。
图30示出了内壳体30与外壳体20的连接状态。内壳体30的前端38从外壳体20伸出，键部32被接纳在外壳体20的槽中并抵靠突出部22，从而限制外壳体20相对于内壳体30朝向前端38的运动，防止外壳体20脱离内壳体30。卡合结构35被外壳体20覆盖。柔性臂25抵靠阻挡部37，柔性臂25处于初始状态，此时，外壳体20处于第一位置。当外壳体20受到向后的外力时(下文将详述)，外壳体20相对于内壳体30向后端39移动并且柔性臂25被挤压，即外壳体20处于第二位置。当外力消除后，在柔性臂25的弹性回复力作用下，外壳体20相对于内壳体30向前端38运动，受键部32的限制，从而回到第一位置。并且，键部32或极性键32还能与卡钩元件90上的极性部或极性槽配合，以区分光纤对接时的极性。
如图31所示，后柱体50与内壳体30通过螺纹连接。具体地，后柱体50包括后主体头端58和后主体尾端59。后主体头端58包括内螺纹53，使得后柱体50可以螺纹连接至内壳体30的外螺纹部33。抵止件46设置在内壳体30内。弹簧45的一端被接纳在抵止件46内，在弹簧45的弹性 力作用下，套箍40能够从内壳体30的前端38露出，并相对于内壳体30前后移动。当光纤连接器11与适配器12连接时，套箍40可以利用弹簧45的弹性沿轴向前后运动，从而与对接的连接器实现紧密连接，消除间隙。
连接器垫圈49可构造为台阶的形式，例如使得连接器垫圈49的中间部分的厚度大于连接器垫圈49的边缘部分的厚度。内壳体30在连接器垫圈49的边缘部分接触连接器垫圈49，抵止件46在连接器垫圈49的中间部分接触连接器垫圈49。
如本领域技术人员所熟知的，光缆55连接至后主体尾端59。卡环60套设在光缆55外面，也连接至后主体尾端59。如图31所示，卡环60包括固定齿62，固定齿62向卡环60的内部凸出，以挤压的方式将光缆55的护套固定至后主体尾端59。尾套65则在后端套设在卡环60的外表面。
第七优选实施方式
本申请的第七优选实施方式提供一种光纤适配器12，图25以及图32-39示出了该光纤连接器12。在本实施方式中，轴向为与光纤延伸的方向平行的方向，轴向方向也称为前后方向，横截面为垂直于轴向方向的截面。
在图25中，根据本申请的光纤适配器12包括第一端部13(也可称之为第一接收部13)和第二端部14(也可称之为第二接收部14)。第一端部13和第二端部14分别用于连接光纤连接器。
在图32中，光纤适配器12包括适配器壳体70、第一密封件80、卡钩元件90和第二密封件84。第一密封件80和卡钩元件90被接纳在适配器壳体70中，并且适配器壳体70可通过螺栓87和螺栓垫圈88安装至设备。
在图33中，第一端部13与第二端部14被挡壁76分隔开。挡壁76可包括接收槽79，从而接纳第二密封件84。由于第二密封件84设置在第一端部13与第二端部14之间，当光纤适配器12安装至设备时，第二密封件84位于适配器壳体70与设备的外表面之间，防止水从设备外壳的开口进入设备内部。
在图34中，光纤适配器12包括从第一端部13到第二端部14贯通的通道71，从而在适配器12的内部建立光通信通道。通道71中设置有分隔壁73，将通道71划分为第一通路71a和第二通路71b，第一通路71a位于 第一端部13，第二通路71b位于第二端部14。分隔壁73中部设置有分隔壁通孔74，使得第一通路71a与第二通路71b相连通。第一密封件80设置在第一通路71a和第二通路71b的至少一个中并紧靠分隔壁73设置。第一密封件80被卡钩元件90抵靠在分隔壁73，从而防止水分或湿气进入通路71a或71b。光纤适配器12包括卡钩元件90，卡钩元件90分别设置在第一通路71a和第二通路71b。
如图35所示，第一密封件80的中间部分82的厚度大于其边缘部分83的厚度，使得第一密封件80构造为台阶的形式。当第一密封件80安装在第一通路71a中时，第一密封件80的平面的一侧朝向分隔壁73。
如图36所示，卡钩元件90包括卡钩元件本体96(也可称卡钩主体96)和侧臂93。其中，卡钩元件本体96包括容纳连接器的容纳空间92。侧臂93从卡钩元件本体96延伸。侧臂93的端部设置有钩部95，该钩部95用于与光纤连接器卡锁。优选地，卡钩元件90包括两个对称设置的侧臂93。
适配器壳体70包括卡位部，卡钩元件90包括锁定部，当卡钩元件90安装至通路71a或71b中时，卡位部与锁定部相互配合，以使卡钩元件90锁定在通路71a或71b中，使卡钩元件90连接到适配器壳体70，同时使卡钩元件90将第一密封件80抵靠至分隔壁73。具体地，适配器壳体70包括配合窗78，卡钩元件90包括锁定部94。如图34所示，当卡钩元件90安装至第一通路71a中时，锁定部94被锁定在配合窗78中，使得卡钩元件90与适配器壳体70卡接。
第八优选实施方式
本申请的第八优选实施方式提供一种光纤连接系统300，图26以及图37-39示出了该光纤连接系统300。在本实施方式中，轴向为与光纤延伸的方向平行的方向，轴向方向也称为前后方向，横截面为垂直于轴向方向的截面。
其中，根据本申请第六优选实施方式的光纤连接器11和第七优选实施方式的光纤适配器12组成根据本申请的光纤连接系统300。
如图37所示，光纤连接器11插入光纤适配器12，即第一通路71a，卡钩元件90的钩部95接触内壳体30的倾斜部35b。外壳体20接触卡钩元件90，随着光纤连接器11朝向光纤适配器12移动，外壳体20受到卡 钩元件90的阻挡从而沿与插入方向相反的方向移动。
在图38中，当钩部95沿倾斜部35b的斜坡移动时，伴随光纤连接器11进一步插入，外壳体20被继续向与插入方向相反的方向推动，即将外壳体20朝向第二位置(内壳体30的后端39)推动，露出锁定凹槽35a。
继续插入光纤连接器11，则钩部95移动通过倾斜部35b从而被接纳在锁定凹槽35a中，同时内壳体30挤压第一密封件80。内壳体30的端部可设置倒角，以便于与第一密封件80接触，挤压中间部分82，光纤连接器11进入光纤适配器12中的位置，如图39所示。停止移动光纤连接器11，则外壳体20在柔性臂25的作用下回到第一位置，从而覆盖侧臂93。外壳20的一部分可进入光纤适配器12并位于卡钩元件90的外侧。
出于示例的目的，本申请中的光纤连接器为MPO(多光纤推入式，Multi-fiber Push On)连接器，相应地光纤适配器为与之匹配的MPO适配器。本领域技术人员应理解，本申请的技术方案也能应用于其他类型的连接器。
