本申请要求申请日为2015年6月24日，申请号为201510354546.1，发明名称为“光纤连接器”的中国专利申请的优先权，其全部内容作为整体并入本申请中。
技术领域
本申请涉及通信技术领域，具体涉及光纤通信技术领域，尤其涉及一种光纤连接器。
背景技术
在光纤通信系统的日常维护中，特别是大型数据中心里，光纤互联使用的场景越来越多，设备的种类也越来越多。但光纤接口尚未完全统一为一种，例如，常见有LC、FC、SC的接口。因此在各种测试与维护过程中，需要将不同类型的光纤接口相互对接时，就要用到光纤转换器进行对接。
目前已有的单个光纤接口转换器对各种接口的转换单一，例如，LC-FC转换器，LC-SC转换器等。一种转换器只可以实现一种类型的光纤接口的转换。当一次日常维护中涉及多种光纤接口类型时，就需要携带多种光纤转换器，以适应不同类型光纤接口的互联。或者，有时候工作人员到了现场才发现自己带的光纤转换器类型与现场的光纤接口类型不匹配，他需要返回单位再次取光纤转换器，使得整个维护工作耗时过长，影响了工作人员的工作效率。
因此，为了满足不同类型光纤接口之间的转换需要，提高光纤通信系统日常维护效率，需要一种能够连接多种类型光纤接口的光纤连接器。
发明内容
鉴于现有技术中的上述缺陷或不足，期望能够提供一种能够连接多种类型光纤接口的光纤连接器。为了实现上述一个或多个目的，本申请提供了一种光纤连接器。
本申请提供的光纤连接器，包括：壳体；所述壳体相对的两个表面上分别设置有两个以上不同类型的光纤转接器；设置在所述壳体内部的连接组件和内部光纤，所述连接组件用于将所述内部光纤连接到不同的光纤转接器。
本申请提供的光纤连接器，在壳体相对的两个表面上分别设置有两个以上不同类型的光纤转接器，且可以通过设置于壳体内部的连接组件和内部光纤对光纤接口之间的连接关系进行改变，实现了多种类型光纤接口之间的转换。
附图说明
通过阅读参照以下附图所作的对非限制性实施例所作的详细描述，本申请的其它特征、目的和优点将会变得更明显：
图1示出了根据本申请提供的光纤连接器的一个实施例的结构示意图；
图2示出了根据本申请一个实施例提供的光纤连接器的一种实现的结构示意图；以及
图3示出了根据本申请提供的光纤连接器的又一个实施例的结构示意图。
具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本 申请。
光纤接口可以包括很多类型，例如，可以包括：FC、SC、LC、D4、DIN、MU等各种类型。FC型光纤连接器外部加强方式为采用金属套，紧固方式为螺丝扣。SC型光纤连接器外壳呈矩形，采用插针与耦合套筒的结构，其插针的端面多采用PC或APC型研磨方式。紧固方式采用插拔销闩式，不需旋转。此类连接器插拔操作方便，介入损耗波动小，抗压强度较高，安装密度高。LC型光纤连接器采用操作方便的模块化插孔闩锁机理制成。其所采用的插针和套筒的尺寸是普通SC、FC所用尺寸的一半，为1.25mm，这样可以提高光纤配线架中光纤连接器的密度。D4型光纤连接器采用的插针和耦合套筒的结构尺寸与FC型相同，端面处理采用PC研磨方式。与FC型连接器相比，D4型光纤连接器的结构要复杂一些，其内部金属结构中有控制压力的弹簧，可以避免因插接压力过大而损伤端面。另外，这种连接器的机械精度较高，因而介入损耗值较小。MU型光纤连接器是以SC型连接器为基础研发出来的最小的单芯光纤连接器。MU型光纤连接器采用1.25mm直径的套管和自保持机构，其优势在于能实现高密度安装。
在光纤通信的日常维护中，当需要将光纤接口互联时，由于现场的光纤接口类型可能不确定，因此，需要携带多种光纤连接器，从而实现不同接口类型的光纤互联互通。
本实施例提供的光纤连接器，将不同类型的光纤接口集成在一个装置中，且连接光纤接口的内部尾纤可以移动，从而可以改变光纤接口之间的互联关系，实现了多种光纤接口之间的互联。
请参考图1，其示出了根据本申请提供的光纤连接器的一个实施例的结构示意图。
如图1所示，本实施例提供的光纤连接器可以包括：壳体101、设置于壳体相对的两个表面上的多个光纤转接器、以及设置于壳体内部的连接组件110和内部光纤111。连接组件110可以将内部光纤111连接到不同的光纤转接器。
在本实施例中，在壳体相对的两个表面上可以分别设置两个以上不同类型的光纤转接器。各光纤转接器均可以包括两个光纤接口，分 别设置于壳体表面的内外两侧。可以理解，为了实现多种光纤接口之间的转换，对于壳体的任一表面其外侧的光纤接口为不同类型；对于壳体任一表面内侧的光纤接口，可以为同一类型，以实现与内部光纤111进行连接。其中，对于壳体的两个表面，其内侧的光纤接口类型可以相同，也可以不同。如图2所示，对于两个壳体表面，其中一个表面内侧的光纤接口为SC型，如光纤转换器202、203、204、205；另一个表面内侧的光纤接口为LC型，如光纤转接器206、207、208、209。
设置于两个表面上的光纤转接器数量可以相同，也可以不同。在一种实现中，可以在壳体其中一个表面上设置4个光纤转接器102、103、104、105，另一个表面上也设置4个光纤转接器106、107、108、109。其中，光纤转接器102、103、104、105可以是不同类型的光纤转接器；光纤转接器106、107、108、109也可以是不同类型的光纤转接器。对于设置于不同表面上的光纤转接器，例如，转接器102和106，其类型可以相同，也可以不同。
在本实施例中，壳体内部的连接组件110可以将内部光纤111连接到不同的光纤转接器。例如，如图1中所示，通过连接组件110和内部光纤111，可以将光纤转接器103和109连接起来，从而可以实现将接口类型分别与光纤转接器103、109相同的设备进行互联。可以理解，通过连接组件也可以实现其它光纤转接器之间的连接，例如，可以将其中一个表面的任一光纤转接器与另一表面的任一光纤转接器连接，从而实现多种类型光纤接口之间的互联。
在本实施例的一个可选实现方式中，内部光纤111可以是单模光纤或多模光纤。单模光纤为只能传输一种模式的光纤。其中心玻璃芯很细，可以使用于长距离、大容量光纤通信系统，光纤局部区域网或各种光纤传感器中。多模光纤为在给定的工作波长上可以传输多种模式的光纤。由于多模光纤中传输的模式多达数百个，各个模式的传播常数和群速率不同，使光纤的带宽窄，色散大，损耗也较大，只适用于中短距离和小容量的光纤通信系统。为了适应不同系统的使用，本实施例提供的光纤连接器中内部光纤111可以是单模光纤或多模光 纤。当内部光纤111采用单模光纤时，例如单模PC/UPC尾纤，光纤连接器可以用在长距离、大容量光纤通信系统中。对于APC和多模光纤，对应更改光纤转换器和内部光纤即可实现。这种情况下，光纤连接器则可以用在中短距离和小容量的光纤通信系统中。
本实施例提供的光纤连接器，在壳体相对的两个表面上分别设置有两个以上不同类型的光纤转接器，且可以通过设置于壳体内部的连接组件和内部光纤对光纤接口之间的连接关系进行改变，实现了多种类型光纤接口之间的转换。
在光纤通信系统中，有些光纤接口使用较多，例如，LC、SC、FC接口。因此，如何能够实现这几种接口之间的互联，对提高光纤通信系统的作业效率有较大影响。
请参考图3，其示出了根据本申请提供的光纤连接器的又一个实施例的结构示意图。
如图3所示，本实施例提供的光纤连接器，在相对的两个表面上分别设置有3个不同类型的光纤转接器，如光纤转接器301、302、302。其中，对于其中一个表面，其外侧的光纤接口分别为LC、SC、FC接口，内侧的光纤接口均为SC接口。也即对于任一表面来说，均设置有LC-SC型光纤转接器301，SC-SC型光纤转接器302，FC-SC型光纤转接器303。因此，当一个表面的光纤转接器301和另一个表面的光纤连接器301建立连接时，可以实现LC-LC光纤接口类型的转换。当一个表面的光纤转接器301和另一个表面的光纤连接器302建立连接时，可以实现LC-SC光纤接口类型的转换。当一个表面的光纤转接器301和另一个表面的光纤连接器303建立连接时，可以实现LC-FC光纤接口类型的转换。当一个表面的光纤转接器302和另一个表面的光纤连接器302建立连接时，可以实现SC-SC光纤接口类型的转换。当一个表面的光纤转接器302和另一个表面的光纤连接器303建立连接时，可以实现SC-FC光纤接口类型的转换。当一个表面的光纤转接器303和另一个表面的光纤连接器303建立连接时，可以实现FC-FC光纤接口类型的转换。因此，使用该光纤连接器，可以实现LC-LC、LC-SC、LC-FC、、SC-FC、FC-FC光纤接口类型的转换。
可以理解，为了实现内部光纤111与各光纤转接器靠壳体内侧光纤接口之间的连接，本实施例中内部光纤111的接口类型也采用SC接口类型。
本实施例提供的光纤连接器，在壳体内部有平行设置的两个滑轨304，各滑轨上分别设置有一个可移动拨钮305。可移动拨钮305与内部光纤111的两端分别连接。可移动拨钮305可以沿着滑轨移动，当可移动拨钮305移动时，内部光纤111的两端也随着一起移动。因此，通过拨动可移动拨钮305可以将内部光纤111的两端移动到对应不同光纤转接器的位置。
本实施例提供的光纤连接器，还包括与各光纤转接器对应设置的多个凹槽306。凹槽306的位置与各光纤转接器的位置相对应。当可移动拨钮305被拨动到任一凹槽306的位置时，凹槽306可以容纳可移动拨钮305，即可移动拨钮305可以被拨动到任一凹槽306内，此时，内部光纤111可以连接到该凹槽对应的光纤转接器的内侧接口上。如图3所示，通过拨动可移动拨钮305，可以将内部光纤111连接到壳体一个表面的光纤转接器303和壳体另一个表面的光纤转接器302上，从而可以实现FC-SC光纤接口类型的转换。通过设置于壳体内部的凹槽306，在转换光纤接口的连接关系时，可以精确定位各光纤接口的位置，提高了操作速率和准确度。
为了实现多种光纤接口类型之间的转换，可以将内部光纤111连接到光纤连接器其中一个表面的任一光纤转接器和另一表面的任一光纤转接器。在移动内部光纤111的过程中，内部光纤有可能发生缠绕。因此，本实施例提供的光纤连接器还包括设置在壳体内部的多个固定支撑杆307，用于防止内部光纤111发生缠绕。如图3所示，固定支撑杆可以将内部光纤111限制在一定的区域内，在该区域内内部光纤111不会多次交叉，从而避免了内部光纤111相互缠绕。
本实施例提供的光纤连接器，在壳体相对的两个表面上分别设置有3个不同类型的光纤转接器，且可以通过设置于壳体内部的滑轨、可移动拨钮、以及凹槽使内部光纤连接到不同的光纤转接器，实现了LC-LC、LC-SC、LC-FC、SC-SC、SC-FC、FC-FC光纤接口类型的转 换。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离所述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
