参看图2至图6，为本发明的带状光纤连接器的第一实施例中插头的示意图，插头1包括插头壳体10以及收容在壳体10中的第一光纤固定组件11和对中芯体12。插头壳体10的前端具有对中芯体容置腔101，对中芯体12收容在该对中芯体容置腔101内，插头壳体10的前端面开有正对对中芯体12的开口102，对中芯体12与对中芯体容置腔101可采用过盈配合的方式，以使对中芯体12固定在对中芯体容置腔101内。在本实施例中对中芯体12为陶瓷芯体，其上开有多条对中通道121，该对中通道121为设在陶瓷芯体上的通孔,为了使裸光纤更容易的插入到对中通道121中,对中通道121的两端开有倒角,对裸光纤起到导向的作用。为了方便对中芯体12的装配并保证装配精度，在对中芯体12的顶面和底面都设有导向凸块122和123，对中芯体容置腔101的内壁则对应的设有导向槽103，装配时，导向块122放入导向槽103中然后将对中芯体12推入到对中芯体容置腔101内。
第一带状光纤31由插头1的尾端进入插头壳体10内，第一带状光纤31包括带有包皮的包皮段310以及剥去包皮的护套段311和剥去护套层的第一裸纤段312，护套段311的每根光纤的直径为250微米，第一裸纤段312的每根裸纤的直径为125微米，第一裸纤段312也即第一带状光纤31的头部，具有多根第一裸纤。第一带状光纤31的护套段311由第一光纤固定组件11固定在插头壳体10内，第一光纤固定组件11包括光纤尾座110以及盖在光纤尾座110上的外框盖板111，第一带装光纤31的护套段311被压紧在光纤尾座110和外框盖板111之间，或者护套段311通过粘接剂粘贴在光纤尾座110和外框盖板111之间同样可以达到紧固目的，第一裸纤段312的每根第一裸纤插入到相应的对中通道121中，第一裸纤占据对中通道121的一部分。光纤尾座110包括一平板112以及设置在平板112侧边的限位块113，插头壳体10具有与限位块113适配的限位槽104，外框盖板111的底面设有定位销114，插头壳体10具有与定位销114适配的定位孔105中。装配时，对中芯体12先装入到对中芯体容置腔101中，然后将光纤尾座110放入到插头壳体10中，限位块113卡入限位槽104中实现对光纤尾座110的定位，然后将处理好的第一带状光纤31有插头壳体10的尾端插入到插头壳体中，第一裸纤段312的每根第一裸光纤插入到相应的对中通道121中，然后盖上外框盖板112，外框盖板112的定位销114插入到定位孔105中实现对外框盖板112的定位，外框盖板112的前端具有一台阶，插头壳体10上具有与该台阶对应并与该台阶配合的台阶，也对外框盖板112起到定位的作用。
插头1的插头壳体10的两侧设有弹性的倒扣106，插座2的插座壳体20的内壁具有与该倒扣106适配的扣位201，插头1插入插座2中时，倒扣106扣入扣位201中。为了保证插头1和插座2的精确配合以及两端光纤的准确对中，对中芯体底面凸块123与插座壳体内壁设有的精确配合定位槽205精密配合，同时为了保证插头与插座的配合强度防止它们相对左右晃动，插头壳体10的前端的表面上设有多条凸筋107，在插座壳体20的内壁则相应的设有多条定位槽202。
如图7至图8所示，为本发明的带状光纤连接器的第一实施例中插座的示意图，插座2包括插座壳体20，以及收容在插头壳体20中的第二光纤固定组件21。第二带状光纤32由插座壳体20的尾端进入到插座壳体20并由第二光纤固定组件21固定，第二带状光纤32包括具有包皮的包皮段320，用于固定第二带状光纤32的定长裸纤段321，以及剥去包皮的护套段322，以及第二裸纤段323，第二裸纤段323也即第二带状光纤的头部，具有多根第二裸纤。
第二光纤固定组件21包括光纤压板210，插座壳体20的尾端具有光纤固定V槽203，光纤压板210盖在所述固定V槽203上,定长裸纤段321排列在光纤固定V槽203中，在固定V槽203中点粘结剂，光纤压板210通过粘接剂将定长裸纤321段粘接压在光纤固定V槽203中。第二光纤固定组件21还包括一光纤整形压片211，光纤整形压片211设置在插座壳体20内并位于光纤压板210的前方，光纤整形压片211将第二带状光纤32的护套段322压在插座壳体20的底面上，对第二带状光纤32起到整形定位的作用。插座壳体20的底面还有具有光纤排列V槽204，第二带状光纤32沿光纤排列V槽204向前延伸，第二裸纤段323悬空在插座壳体20的前端，当插头1插入插座2时，第二裸纤段323的第二裸纤插入到对中芯体12的响应的对中通道121中，第二裸纤在对中通道121中与第一裸纤实现端面对接。第二裸纤和第一裸纤在对中时，具有轻微的弯曲形变，以使得二者端面在一定的压力下对接，保证光路良好导通。由于第一裸光纤和第二裸光纤都不是固定在对中芯体中，因此二者的对接称之为活动对接。
图9示出了本发明的带状光纤连接器的第一实施例的插头1与插座2配合时的剖面示意图，由图可以看出了，第一裸纤和第二裸纤在对中芯体12的对中通道中121实现端面对接，以实现光路的续接。
如图10至图13所示，为本发明的带状光纤连接器的第二实施例的插头的示意图。由于裸纤的直径只有125微米，在对中芯体12上直接加工通孔来形成对中通道非常不易，为了使对中芯体12更易制造，在本实施中将对中芯体12分为两部分，包括V槽板123和盖在V槽板123上的V槽盖板124，相对于加工小尺寸的通孔来说，V槽的加工更为容易实现。V槽板123的具有对中V槽125和排列V槽126，对中V槽125即为对中通道，V槽盖板124只盖在对中V槽125上，排列V槽126裸露，第一带状光纤31的第一裸纤段312从上方向下装配到123的V槽中，并在V槽126上点上粘接剂预固定光纤，为了方便第二裸纤进入到对中V槽中，在所述对中V槽125与插座的裸纤插入端设有倒角，可以起到导向的作用。本实施例的插头1的其他结构与第一实施例中插头的结构相同，不再赘述。本实施例的插座的结构与第一实施例中插座的结构相同。
图14为本发明的带状光纤连接器的第二实施例的插头1与插座2配合时的剖面示意图，由图可以看出了，第一裸纤和第二裸纤在对中芯体12的V槽板123的对中V槽125中实现端面对接，以实现光路的续接。
图15和图16分别示出了本发明的带状光纤连接器的两种应用形式，图15中，带状光纤连接器与面板垂直，在图16中，带状光纤连接器与面板倾斜一定角度，本发明的带状光纤连接器具有很好的适用性，适用各种应用场合。
发明的带状光纤连接器，包括插头和插座，插头壳的前端收容有对中芯体，该对中芯体具有多条对中通道，插头插入插座时，第一带状光纤前端的第一裸纤和第二带状光纤的前端的第二裸纤在所述对中通道内现实端面对接。本发明的带状光纤连接器具有结构简单，使用方便，可重复插拔的优点。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
