实际应用时，光缆17可以为具有防尘、防水等功能的光缆。
在一实施例中，如图3A及3B所示，引导保护套筒12与光纤主体11的后套115相连接，引导保护套筒12的内壁设置有第一定位键121及第一定位槽122，后套115外壁的对应位置设置有第二定位槽1151及第二定位键1152，通过第一定位键121与第二定位槽1151的扣合、以及第一定位槽122与第二定位键1152的扣合，引导保护套筒12与后套115牢固地结合在一起，采用键槽、槽键的结构，既可以起到定位作用，又可以防止引导保护套筒12与后套115二者之间的转动。

在一实施例中，如图6所示，该光纤连接器还可以包括：设置有螺纹的防尘帽19，当本发明实施例提供的光纤连接器未连接光纤转接器时，可以将防尘帽19通过螺纹与连接螺帽15连接，起到防尘、防水等作用；这里，为了保证光纤连接器的密封性，如图6所示，还可以在防尘帽19与连接螺帽15之间增设密封圈20；另外，还可以让防尘帽19通过连接件21与连接螺帽15连接，如此，可以防止防尘帽19的丢失，而且方便使用。实际应用时，如图6所示，可以将连接件21的与连接螺帽15连接的一端设置在卡圈处，连接件21的与防尘帽19连接的一端设置在紧贴密封圈20处。
其中，防尘螺帽19的材质可以为塑胶材料，比如PEI或尼龙等；密封圈20的材质可以为各种硅胶、马蹄胶等；连接件21的材质可以为塑胶材料，比如尼龙等。
实际应用时，如图7所示，可以将O型圈71安装在安装面板72的沟槽处，本发明实施例提供的光纤连接器73通过引导保护套筒的引导作用与光纤转接器74对接，将连接螺帽通过螺纹固定在光纤转接器上即可完成安装。
本发明实施例提供的光纤连接器，引导保护套筒套接在光纤主体上，保护热缩套包覆被卡扣固定的光缆及卡扣，连接螺帽套接在连接有引导保护套筒的光纤主体上，护套套接在连接螺帽没有包覆的光纤连接器的其它区域，如此，使得本发明实施例提供的光纤连接器具有防水、防尘等功能，可以应用在室外等多变环境(比如架空的环境等)中。
另外，引导保护套筒与后套采用键槽、槽键的结构结合在一起，如此， 既能有效地起到定位作用，又能有效地防止引导保护套筒与后套二者之间的转动。
当后套强装到引导保护套筒内时，设置在引导保护套筒内壁上的倒钩将后套牢固的固定，如此，使得引导保护套筒能与后套更加牢固地结合在一起。
两个位置关系为180度的卡扣卡合防水光缆，两个卡扣一前一后将防水光缆卡合，从而保证了一定的拉力效果，如此，能有效地固定防水光缆。
除此以外，当本发明实施例提供的光纤连接器未连接在光纤转接器时，可以将防尘帽通过螺纹与连接螺帽连接，起到防尘、防水等作用。
设置在防尘螺帽与连接螺帽之间的密封圈，能有效地保证光纤连接器的密封性。
通过连接件连接防尘帽及连接螺帽，能有效地防止防尘帽的丢失，而且方便使用。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。
