具体实施方式
如图1至图12所示，在本实用新型的预埋式光纤连接器第一实施例中，所述预埋式光纤连接器包括插芯95、设置于所述插芯95内的预埋光纤15、固定所述预埋光纤外皮的夹头80及固定另一光纤外皮的尾壳20，所述预埋式光纤连接器还包括固定槽体50、夹头80和尾壳20的固定装置，所述夹头80的两端分别连接有槽体50和尾壳20。预埋光纤是在生产过程中，将一段预埋光纤15插入插芯95，并且点胶进行热固化，然后再研磨，这样，组装后的连接器的端面就跟普通的跳线没什么区别了。
其中，所述固定装置包括由外至内设置的内框套10、复位弹簧30、固定裸纤并与所述内框套10一起防止所述裸纤旋转的法兰40、限位卡60、锁紧光纤的夹头80及协助所述夹头80锁紧的推管90。所述限位卡设置于所述内框套10上，所述复位弹簧30设置于所述内框套10和推管90之间。下面对各部件分别说明：所述槽体50包括凸起、第一通孔以及“V”槽，所述凸起为梯形体，所述第一通孔为设置于所述槽体50的三角通孔。槽体50是由三部分组成，包括凸起、第一通通孔以及V槽，凸起部分成梯形体，第一通孔为三角孔，孔只在上槽开，下槽没有孔。所述槽壳70为中空圆柱体，所述中空圆柱体设置有方便所述槽体50插入的通槽。
槽壳70的形状为中空圆柱体，上开通槽，方便V槽的插入。当V槽插入槽壳70中，凸起能够部分露在槽壳70外边。所述夹头80包括导向的外倒角、主体、变形槽、限位体、内圆柱、第二通孔以及收紧的压爪，所述压爪为上下分布的两个压爪。所述推管90是由大径、小径两个的金属管连接构成，所述大径为其一端推入后对“V”槽产生压力并收紧从而固定裸纤的大径。其中，大径的一端推入后对V槽产生压力，V槽收紧从而固定裸纤。小径的一端推入会使压爪产生形变，两个压爪抱紧从而固定光纤。内框套10对普通连接器的内框套10进行了改进，由于弹簧30的固定方法的改变，本内框套10引入了类似压线卡的结构，生产过程中，先将弹簧30压紧，然后插入限位卡60，再松开弹簧30，这样弹簧30就会被固定好。
所述尾壳20包括导向体、紧固体、卡台、卡孔以及光缆通孔。尾壳20是配合内框套10一起用的。导向体是插入内框套10，防止旋转，紧固体插入内框套10后，防止光缆的后退，而将压线卡通过卡台上的卡孔插入光缆外皮，就可以固定整个光缆。法兰40除了固定插芯95外，还可以跟内框套10一起，防止插芯95旋转。
本结构中，法兰40和槽壳70是融为一体。
本新型工作原理如下：夹头80的内圆柱插入槽壳70，推管90推入后会挤压变形槽的本体，从而使本体的两个压爪互相抱紧，达到固定这部分光纤的作用。尾壳20和内框套10配合使用，当尾壳20的紧固体插入内框套10后，通过压线卡，就可以固定整个光缆了。
本新型使用步骤：
1、将连接体放到组装台的左边，并且将其固定，然后移动挡板至插芯95处，使挡板紧贴插芯95的端面，固定挡板。
2、将光缆依次穿过护套，尾壳20，然后剥纤，制作光纤端面。
3、将做好的纤通过夹头80插入，然后通过组装台上的固定装置将光缆固定。
4、将推管90推入，使其尾端基本与夹头80的尾端一致。
5、将尾壳20推入内框套10，然后压下压线卡。
6、将护套推上，并且装上外框套。
这样，整个的连接器就组装完毕。当然，我们也可以检查，连接器的端面情况，以确定要不要再抛光。由于插芯里有一段预埋光纤，而这段光纤的端面是经过工厂胶结并研磨的，所以从性能到稳定性上都得到了保证。
