Description

一种光纤分纤箱 技术领域
本发明涉及光纤技术领域，特别涉及一种光纤分纤箱。
背景技术
随着光纤技术的发展，光缆在通信中的应用得到了普及，比如，越来越多的用户采用光纤宽带进行上网。用户可以通过光纤分纤箱(Fiber Access Termination，FAT)将光纤引到户内。
具体的，FAT包括箱体和光纤适配器等部件，其中，箱体上会设置有光缆入口和光缆出口(光缆往往包含多根光纤)，光缆入口中的光缆的一根光纤可以通过光纤连接头与光纤适配器的一端连接(当该FAT具有多个光纤适配器时，每个光纤适配器的一端均可与光缆入口中的光缆的一根光纤连接)，光纤适配器的另一端可以与连接有光纤连接头的光纤(可称为入户光纤)连接，包含剩余的其他光纤的光缆可以从光缆出口引出，其中，光纤适配器和光纤连接头起到连接两根光纤的作用。当用户想要开通光纤宽带时，连接有光纤连接头的光纤可以通过光纤连接头与光纤适配器的另一端连接，将光纤引进户内。目前，FAT包括的光纤适配器的数量是一定的，即该FAT可将光纤引进户内的户数是一定的，工作人员可以根据目前开通光纤宽带的户数，选择光纤适配器数量合适的FAT设置在楼道内等位置。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
当根据当前户数设置FAT后，又有其他用户开通光纤宽带时，由于原先设置的FAT的光纤适配器的数量不够，工作人员往往需要将原先设置的FAT拆除，重新设置一个光纤适配器的数量满足当前户数的FAT，操作比较繁琐，从而，导致操作效率较低。
发明内容
为了实现提高操作效率的目的，本发明实施例提供了一种光纤分纤箱，所述技术方案如下：
提供了一种光纤分纤箱，光纤分纤箱可以包括第一组件和第二组件，第一组件可以包括第一箱体和光纤适配器，第二组件可以包括第二箱体、分光器、光纤连接头和多个光纤适配器，其中：第一组件的光纤适配器可以设置于第一箱体的外部，第一箱体上可以设置有光缆入口和光缆出口；分光器可以设置于第二箱体的内部，光纤连接头和第二组件的多个光纤适配器设置于第二箱体的外部；光纤连接头的第一端与第一组件的光纤适配器可拆卸式连接，光纤连接头的第二端与分光器的输入端口连接，分光器的每个输出端口分别与第二组件的一个光纤适配器连接。
本发明实施例所示的方案，光纤分纤箱可以包括两个组件(即第一组件和第二组件)，第一组件的第一箱体上可以设置有光缆入口和光缆出口，第二组件可以与第一组件可拆卸式连接。这样，当根据当前户数设置光纤分纤箱后，又有其他用户开通光纤宽带时，工作 人员可以用包含更多光纤适配器的第二组件，替换之前设置的光纤分纤箱的第二组件，无需工作人员将第一组件进行拆除，从而，可以提高操作效率。
在一种可能的实现方式中，第二组件还包括多个防尘帽，多个防尘帽中的每个防尘帽分别设置在第二组件的一个光纤适配器上。
这样，当光纤适配器没有使用时，可以防止光纤适配器被污染。
在一种可能的实现方式中，第一箱体上设置有导向槽，第二箱体上设置有突起，导向槽和突起相配合。
这样，工作人员在连接第一组件和第二组件时，可以更准、更快速的实现光纤适配器和光纤连接头的连接。
在一种可能的实现方式中，第一组件还包括第一固定部件，第一箱体包括上箱体和下箱体；上箱体和下箱体可以通过第一固定部件固定。
在一种可能的实现方式中，第一固定部件包括多个螺钉，上箱体和下箱体通过多个螺钉固定。

具体实施方式
图1是本发明实施例提供的一种光纤分纤箱。参见图1，光纤分纤箱包括第一组件1和第二组件2，第一组件1包括第一箱体11和光纤适配器12，第二组件2包括第二箱体21、分光器22、光纤连接头23和多个光纤适配器24，其中：第一组件1的光纤适配器12设置于第一箱体11的外部，第一箱体11上设置有光缆入口111和光缆出口112；分光器22设置于第二箱体21的内部，光纤连接头23和第二组件2的多个光纤适配器24设置于第二箱体21的外部；光纤连接头23的第一端与第一组件1的光纤适配器12可拆卸式连接，光纤连接头23的第二端与分光器22的输入端口连接，分光器22的每个输出端口分别与第二组件2的一个光纤适配器24连接。
在实施中，光纤分纤箱可以包括第一组件1和第二组件2，其中，第一组件1可以单独进行工作，也可以与第二组件2结合进行工作。第一组件1可以包括第一箱体11和光纤适配器12，其中，光纤适配器12可以设置于第一箱体11的外部。第一箱体11上还可以设置有光缆入口111和光缆出口112，其中，第一组件1投入使用时，光缆可以从光缆入口111进入第一箱体11内，可以通过光缆出口112从第一箱体11引出，第一箱体11的材料可以是塑料。
第一组件1还可以包括光纤熔接部件和预制有光纤连接头的尾纤，其中，光纤熔接部件可以起到存储光缆和保护光纤的作用，光纤熔接部件和预制有光纤连接头的尾纤设置于第一箱体11的内部，尾纤的另一端通过预制的光纤连接头与光纤适配器12的一端连接。当第一组件1投入使用时，工作人员可以将光缆入口111进入的光缆中的一根光纤与尾纤熔 接，当用户想要开通光纤宽带时，预制有光纤连接头的光纤(可以称为入户光纤)可以通过光纤连接头与光纤适配器12的另一端连接，将光纤引进户内。也就是说，当第一组件1投入使用时，光纤适配器12的一端可以与设置于第一箱体11内部的尾纤的预制光纤连接头连接，另一端可以与通过光纤连接头与入户光纤连接。
第二组件2可以包括第二箱体21、分光器22、光纤连接头23和多个光纤适配器24，其中，分光器22可以设置于第二箱体21的内部，光纤连接头23和第二组件2的多个光纤适配器24可以设置于第二箱体21的外部，光纤连接头23的第二端与分光器22的输入端口连接(其中，光纤连接头23的第二端与分光器22的输入端口是通过光纤连接)，分光器22的每个输出端口分别与第二组件2的一个光纤适配器24连接(其中，分光器22的每个输出端口可以连接有预制有光纤连接头的光纤，即分光器22的每个输出端口可以通过该输出端口的光纤连接头与第二组件2的一个光纤适配器24连接)。第二组件2可以与第一组件1结合进行工作，当第二组件2与第一组件1结合进行工作时，第二组件2的光纤连接头23的第一端可以与第一组件1的光纤适配器12可拆卸式连接，每个光纤适配器24可以分别与一个入户光纤连接，其中，光纤适配器12和光纤连接头23的示意图如图2所示。由于第二组件2包括多个光纤适配器24，因此，可以通过更换包含不同数目光纤适配器12的第二组件2，来改变光纤分纤箱的容量(即改变光纤分纤箱的光纤适配器的数目)。这样，当根据当前户数设置FAT后，又有其他用户开通光纤宽带时，工作人员可以通过将原先的第二组件更换为包含更多光纤适配器的第二组件，来增加FAT的光纤适配器的数量，无需工作人员将第一组件拆除，重新设置一个光纤适配器的数量满足当前户数的FAT，从而，可以提高操作效率。
另外，第一箱体11可以具有斜面，相应的，第二箱体21可以具有与第一箱体11的斜面相匹配的斜面，第一组件1与第二组件2连接在一起的示意图如图3所示。
可选的，第二组件还可以包括多个防尘帽25，如图4所示，其中，防尘帽25的数目可以与光纤适配器24的数目一致。多个防尘帽中的每个防尘帽25可以分别设置在第二组件2的一个光纤适配器24上。这样，当光纤适配器没有使用时，可以防止光纤适配器被污染。
可选的，如图5所示，第一箱体11上可以设置有导向槽113，第二箱体21上设置有突起211，导向槽113和突起26相配合。
在实施中，为方便工作人员将第二组件2的光纤连接头23与第一组件1的光纤适配器12进行连接，第一箱体11上可以设置有导向槽113，第二箱体21上设置有突起。这样，导向槽113和突起21可以相互配合，进行预定位，可以使工作人员更准、更快速的实现光纤连接头23与光纤适配器12的连接。
可选的，第一组件1还包括第一固定部件13，第一箱体包括上箱体114和下箱体115；上箱体114和下箱体115可以通过第一固定部件13固定。
在实施中，第一组件1的第一箱体可以由上箱体114和下箱体115可以通过第一固定部件13进行固定，第一组件1的侧视图如图6所示。
可选的，第一固定部件13可以包括多个螺钉131，上箱体114和下箱体115可以通过多个螺钉131固定。
在实施中，第一固定部件13可以包括多个螺钉131，比如可以包括4个螺钉131，如图7所示，上箱体114和下箱体115上可以分别设置有对应多个螺钉131的螺纹。这样，上 箱体114和下箱体115可以通过每个螺钉131和对应每个螺钉131的螺纹进行固定，当光纤分纤箱投入使用时，可以方便工作人员将第一箱体11打开，进而，将光缆中的一根光纤与尾纤熔接在一起。此外，针对第一箱体11具有斜面，第二箱体21具有与第一箱体11的斜面相匹配的斜面的情况，第二箱体21上对应位于第一箱体11底部两个螺钉的位置处，可以设置有通孔。
另外，第二箱体21也包括上箱体和下箱体，其中，第二箱体21的上箱体和下箱体可以按照第一箱体11的固定方式进行固定，也可以采用超声波焊接的方式进行固定。

可选的，第一组件1的光纤适配器12的数目为一个或者多个，光纤连接头23和分光器22的数目与第一组件1的光纤适配器12的数目一致；每个光纤连接头23的第一端与第一组件的一个光纤适配器12可拆卸式连接，每个光纤连接头23的第二端与一个分光器22的输入端口连接。
在实施中，第一组件1可以包括一个光纤适配器，也可以包括多个光纤适配器(比如，可以为2个光纤适配器)，相应的，光纤连接头23和分光器22的数目与第一组件1的光纤适配器12的数目一致，即当第一组件包括一个光纤适配器时，第二组件可以包括一个光纤连接头和一个分光器，当第一组件包括多个光纤适配器时，第二组件可以包括多个光纤连接头和多个分光器。每个光纤连接头23的第一端与第一组件的一个光纤适配器12可拆卸式连接，每个光纤连接头23的第二端与一个分光器22的输入端口连接。
可选的，第一组件1的光纤适配器12和第二组件2的多个光纤适配器24可以为户外光纤适配器。
可选的，第一组件1的光纤适配器12可以设置于第一箱体11的底部；光纤连接头23可以设置于第二箱体21的顶部，第二组件2的多个光纤适配器24可以设置于第二箱体21的底部。
