实施例一
如附图1至4所示，一种光纤连接器插头，包括与带纤相配合的插头组件，所述插头组件包括用于所述带纤端部研磨后的裸纤精确定位的精密导向装置2，以及用于所述带纤限位的带纤固定装置3，所述带纤固定装置3与所述精密导向装置2可拆卸连接，所述精密导向装置2的端面上设置有与所述精密导向装置一体成型的微孔阵列23，所述微孔阵列23与所述带纤1端部研磨后的裸纤间隙配合，且所述带纤1端部研磨后的裸纤的端面外露于所述精密导向装置的端面0.01～0.3mm。所述带纤固定装置3包括带纤定位件和盖板，所述带纤定位件一端的长槽内轴向均布有用于固定所述带纤的光纤固定槽，所述光纤固定槽的上方压设有与所述带纤定位件相配合的盖板，所述精密导向装置2包括插芯和定位导向PIN针，所述定位导向PIN针与轴向贯穿设置在所述插芯一端两侧壁上的沉头孔相配合，所述插芯一端的端面上轴向贯穿设置有用于和所述带纤端部研磨后的裸纤间隙配合的导向槽和微孔阵列，所述导向槽和微孔阵列同轴设置，所述带纤定位件的另一端插设于所述插芯另一端的卡槽内，且所述带纤定位件的另一端的端面与所述沉头孔内的定位导向PIN针的端面相抵触，所述卡槽的底面上贯穿设置有通孔，所述通孔与设置在所述带纤定位件底面上的定位柱相配合，所述带纤套设有胶套，所述胶套与所述带纤定位件的一端相配合。
上述结构设计，使得插芯和带纤定位件两者卡接后形成一体，同时设置在带纤定位件上的光纤固定槽通过其顶部压设的盖板，能够将光纤固定槽内的光纤牢牢压紧，也可以通过夹持，卡接等方式来实现光纤的固定，在此不做赘述。
一种如上所述的光纤连接器插头的装配方法，包括如下步骤：
1).将所述带纤固定装置3与所述精密导向装置2装配；如图5A所示，作为一种优选实施方式，本发明带纤固定装置3包括带纤定位件31和盖板32，所述精密导向装置2包括插芯21和定位导向PIN针22，装配时可将带纤定位件31的另一端卡接到插芯21的另一端的卡槽24内，以使得带纤固定装置3与精密导向装置2稳定可靠的连接为一体。
2).将所述带纤1穿过所述带纤固定装置3，使得所述带纤1端部研磨后的裸纤与所述精密导向装置2相配合，然后将所述带纤与所述带纤固定装置3紧固。如附图5B、5C所示，作为优选实施方式，本发明中的精密导向装置2的端面上设置有与所述精密导向装置一体成型的微孔阵列23，所述微孔阵列23与所述带纤1端部研磨后的裸纤间隙配合，且所述带纤1端部研磨后的裸纤的端面外露于所述精密导向装置的端面0.01～0.3mm。作为优选，可外露0.2mm。此外，作为又一优选，在将带纤与带纤固定装置和精密导向装置相配合之前，可将带纤维进行定长，然后在进行分段剥削，即将带纤1端部研磨后的裸纤作为第一裸纤部，使其与设置在精密导向装置中微孔阵列23相配合；将与精密导向装置中的带纤定位件上的光纤固定槽相配合部分作为第二裸纤部，使其通过胶水固接到光纤固定槽内，并利用设置在光纤固定槽上方的盖板将其压紧。从而能够使得光纤稳定可靠的固定，且一端研磨后的裸纤能够精准的定位，省去了对装配后的裸纤外露端的二次加工，降低了对设备的要求，极大的节约了生产成本。
实施例二
如附图1至4所示，一种光纤连接器插头，包括与带纤1相配合的插头组件，所述插头组件包括用于所述带纤1端部研磨后的裸纤精确定位的精密导向装置2，以及用于所述带纤1限位的带纤固定装置3，所述带纤固定装置3与所 述精密导向装置2可拆卸连接，还包括紧贴于所述精密导向装置2端部的透镜5，所述透镜5内侧的平面压紧裸纤的端面并将裸纤往后推以使得所述精密导向装置2内的带纤1发生弯曲，所述精密导向装置2包括插芯21和定位导向PIN针22，所述定位导向PIN针22与轴向贯穿设置在所述插芯21一端两侧壁上的沉头孔25相配合，所述插芯21一端的端面上轴向贯穿设置有用于和所述带纤1端部研磨后的裸纤间隙配合的导向槽和微孔阵列23，所述导向槽和微孔阵列23同轴设置，所述带纤固定装置3包括带纤定位件31和盖板32，所述带纤定位件31一端的长槽内轴向均布有用于固定所述带纤的光纤固定槽33，所述光纤固定槽33的上方压设有与所述带纤定位件31相配合的盖板32，所述带纤定位件31的另一端插设于所述插芯21另一端的卡槽24内，且所述带纤定位件31的另一端的端面与所述沉头孔25内的定位导向PIN针22的端面相抵触，所述卡槽24的底面上贯穿设置有通孔26，所述通孔26与设置在所述带纤定位件31底面上的定位柱34相配合，所述带纤1套设有胶套4，所述胶套4与所述带纤定位件31的一端相配合。
现有技术中MOLEX的产品，基于现有的MPO插芯演变而来，MPO插芯存在其自身的缺陷：由于外露于插芯一端的裸纤存在纤高不一致的情况，从而导致安装在插芯端面的透镜的焦平面与裸纤的端面偏离，因此使得发射的光束就会成发散状(理想状态为平行光)，最终导致接受端不能将光信号完全耦合至接受端光纤中，造成了光信号的损耗，即增大了整个光纤连接器的***损耗值。同理，在接收端如果接收光纤的端面不在透镜焦平面位置，也会遭成光能量的损失，再次增加光纤连接器的***损耗。
而本发明针对上述缺陷，采用上述结构设计，可有效解决解决现有透镜型光纤连接器多芯光纤间纤高不一致问题，避免了由光纤高度引起的***耦合损 耗，较好的保证了光纤与透镜间的耦合效率，降低了整个连接器方案的***损耗。本发明采用上述技术方案改变了以往光纤连接器的光纤固定方式(以前采用前端固定)，采用了后端固定方案(固定方式可采用多种形式，如胶水固定，夹持固定等)，前端光纤可以在轴向上自由活动。光纤固定时，采用定长方式，保证光纤凸出插芯端面，装配时利用透镜将光纤顶回，让光纤在连接器内部形成弯曲形态，保证光纤端面与透镜背面很好贴合，本发明可以简化透镜型光纤连接器的组装工艺及成本，过去透镜与光纤间通常因存在间隙，而需要特定折射率的胶水来填补透镜与光纤之间的间隙，保证光纤与透镜间的耦合损耗。而本发明因为采用微弯结构设计(即我们假设透镜件的背面是其焦平面，当带纤一端的光纤尾部被固定后，光纤一端的裸纤端面预设为高于插芯端面0.2mm，装配透镜件时，透镜将光纤往后推，利用光纤本体的弯曲应力，可将光纤端面完全贴附于透镜焦平面位置，进而使得光束透过透镜平行射出)，透镜与光纤间的距离没有特别要求，因此透镜的固定方式就可以采用多种形式，如胶黏、卡扣等方式，在此不做赘述。
作为又一优选实施方式，如图5A至5D所示，一种如上所述的光纤连接器插头的装配方法，具体包括以下步骤：
a.将所述定位导向PIN针22***所述插芯21一端两侧壁内的沉头孔25内；作为一种优选实施方式，定位导向PIN针22的尾端的端面略微露出沉头孔25一端的端面，以便于带纤固定件将其压紧。此结构设计，相对于定位导向PIN针22和插芯21一体成型的加工方式，能够更加方便的对组件进行加工，且使得定位导向PIN针22的安装精度更高。
b.将所述带纤定位件31的另一端插设于所述插芯21另一端的卡槽24内，且所述带纤定位件31的另一端的端面与所述沉头孔25内的定位导向PIN针22 的端面相抵触；作为优选实施方式，卡槽的底部还设置有与带纤定位件31底面的定位柱34相配合的通孔，此结构设计，能够有效限制两者之间的自由度，使其紧密配合且形成一个整体，以此便于两者的拆卸以及带纤的安装。
c.将所述透镜5装配到所述插芯21一端的端面上；作为优选实施方式，透镜的两端设置有与定位导向PIN针22相配合的定位孔，且透镜的内侧面涂覆有用于和插芯21一端的端面紧密贴合的胶水，胶水涂覆区的四周开设有溢胶槽，以便于多余的胶水流入溢胶槽，而不会影响到其它部件的外观。
d.将套设有胶套4的带纤1穿过所述带纤定位件31，使得胶套4的一端与所述带纤定位件31的一端相配合；作为一种优选实施方式，带纤定位件31的端面上开设有与所述胶套相配合的安装槽，能够方便的将胶套与带纤定位件31装配到一起，此结构的设计，能够减少带纤与带纤定位件之间的应力，便于带纤的固定。
作为进一步的优选实施方式，所述带纤1端部研磨后的裸纤与所述导向槽和微孔阵列23相配合并使得裸纤外露于微孔阵列23端面抵紧所述透镜5内侧的平面，使得所述精密导向装置2内的带纤1发生弯曲。进而使得带纤端部研磨后的裸纤的端面与透镜焦平面充分贴紧。
e.将所述光纤固定槽33上方的光纤装配到光纤固定槽33内并用胶水紧固，然后在将所述盖板压设到所述光纤固定槽33上方，并使得盖板与带纤定位件31牢牢固定。
作为又一优选的安装方式，在插芯和带纤固定件装配完成后，也可以先将带纤一端的裸纤与插芯上的微孔阵列相配合并使其裸纤端面外露于插芯的端面0.2mm，然后在将光纤固定槽33上方的光纤装配到光纤固定槽33内并用胶水紧固，最后再安装插芯端面的透镜并使其内侧面抵紧外露裸纤的端面，以使得插 芯内的光纤弯曲，进而使得裸纤的端面和透镜的内侧面紧密贴合。
通过上述步骤，能够使得光纤连接器插头形成一个整体，且能够精准的将带纤有效的固定，并能够使得插芯端面处的裸纤端面和透镜的内侧面充分贴合，防止因纤高不一致而导致接受端不能将光信号完全耦合至接受端光纤中，造成了光信号的损耗。此外，通过上述步骤安装的光纤连接器插头，与传统的将光纤***插芯内并通过固化胶与插芯固化在一起，然后对插芯的前端进行精密研磨抛光以达到使用要求的加工方式相比，极大的降低了加工难度，减少了插头的报废，进而有效的降低了插头的生产成本。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
