光缆布线系统和光缆连接组件
相关申请的交叉引用
本申请要求于2014年11月21日递交中国专利局的、申请号为201410673296.3的中国专利申请的权益，该申请的全部公开内容以引用方式并入本文。
技术领域
本发明涉及光纤通信技术领域，更具体地，涉及一种用于光纤到户的光缆连接组件和一种用于光纤到户的光缆布线系统。
背景技术
图1显示一种现有的光纤到户的光缆布线系统。
如图1所示，在现有技术中，用于光纤到户的光缆布线系统一般包括一根主干光缆100’、一个光缆接头盒200’和多根单芯分配光缆101’、102’。多根单芯分配光缆101’、102’通过光缆接头盒200’与主干光缆100’中的多根光纤光学连接。
在图1所示的现有技术中，主干光缆100’和光缆接头盒200’一般布置在一个用户区(以下称为第一用户区)10’的旁边或附近。通过光缆接头盒200’与主干光缆100’光学连接的多根单芯第一分配光缆101’分别与第一用户区10’中的各个第一用户端11’光学连接。
在图1所示的现有技术中，由于主干光缆100’和光缆接头盒200’布置在第一用户区10’的旁边或附近，因此，多根单芯第一分配光缆101’的长度较短，便于铺设。
但是，当需要将光纤连接到远离第一用户区10’的第二用户区20’的各个第二用户端21’时，情况就变得复杂和麻烦。因为需要将与光缆接头盒200’光学 连接的多根单芯第二分配光缆102’拉到远离第一用户区10’的第二用户区20’的各个第二用户端21’。
如图1所示，由于第二用户区20’距离第一用户区10’较远，因此，多根单芯第二分配光缆102’铺设的距离很长，这会造成光缆的浪费，同时，多根松散的单芯第二分配光缆102’显得比较杂乱，这也会影响市容。此外，如果第二用户区20’的各个第二用户端21’不在同一时间开户时，就需要多次长距离铺设单芯第二分配光缆102’，这又增加了人工成本。

图2显示根据本发明的一个实例性的实施例的光纤到户的光缆布线系统。
在本发明的一个实例性的实施例中，如图2所示，光缆布线系统，主要包括：布置在第一用户区10附近的主干光缆100、第一光缆接头盒200和光缆扇出器300；布置在第二用户区20附近的第二光缆接头盒400；和布置在第一光缆接头盒200和第二光缆接头盒400之间的一根主转接光缆310。
在图示的实施例中，第二用户区20远离第一用户区10，例如，第一用户区10位于一条宽马路的一侧，而第二用户区20位于这条宽马路的另一侧，第一用户区10与第二用户区20之间的距离可以在几米至数百米。
图3显示图2中所示的光纤到户的光缆连接组件的立体示意图；和图4显示图3中的光缆扇出器300的立体分解示意图。
如图2、图3和图4所示，在本发明的一个实例性的实施例中，光缆扇出器300将一根主转接光缆310转换成多根分支转接光缆320。
在本发明的一个实例性的实施例中，主转接光缆310可以为8/12芯的ADSS光缆，分支转接光缆320可以为单芯ADSS光缆。
请继续参见图2、图3和图4，在图示的实施例中，多根分支转接光缆320通过第一光缆接头盒200与主干光缆100光学连接。
在本发明的一个实例性的实施例中，多根分支转接光缆320在第一光缆接头盒200中可以通过光学熔接或通过光学连接器与主干光缆100中的多根对应的光纤光学连接(或称为光学接续)。
请继续参见图2、图3和图4，在图示的实施例中，多根单芯第一分配光 缆101通过第一光缆接头盒200与主干光缆100光学连接，并分别光学连接到第一用户区10中的各个第一用户端11。
在本发明的一个实例性的实施例中，多根单芯第一分配光缆101在第一光缆接头盒200中可以通过光学熔接或通过光学连接器与主干光缆100中的多根对应的光纤光学连接(或称为光学接续)。
请继续参见图2、图3和图4，在图示的实施例中，多根单芯第二分配光缆102通过第二光缆接头盒400与一根主转接光缆310光学连接，并分别光学连接到第二用户区20中的各个第二用户端21。
在本发明的一个实例性的实施例中，多根单芯第二分配光缆102在第二光缆接头盒400中可以通过光学熔接或通过光学连接器与一根主转接光缆310中的多根对应的光纤光学连接(或称为光学接续)。
这样，如图2所示，就无需在相距较远的第一用户区10和第二用户区20之间长距离铺设多根单芯第二分配光缆102，从而减少了连接到远离主干光缆100的第二用户区20的单芯第二分配光缆102的铺设长度，降低了材料和施工成本，并且还能够提高市容的美观性。
下面将参照图3和图4来详细说明图2中的光缆连接组件和光缆扇出器300的具体结构。

请继续参见图4，在图示的实施例中，壳体301、302包括基座301和盖子302。在本发明的一个实例性的实施例中，基座301和盖子302被构造成通过弹性卡扣结构3011、3021相互锁定在一起。该弹性卡扣结构3011、3021包括形成在盖子302上的弹性卡钩3021和形成在基座301上的凹槽3011。当盖子302安装到基座301上时，弹性卡钩3021卡扣到凹槽3011中，从而将基座301和盖子302相互锁定在一起。
在本发明的一个实例性的实施例中，如图4所示，在基座301的第一端上形成有一个筒状凸起部303，一根主转接光缆310穿过筒状凸起部303；并且光缆扇出器300还包括一个热缩管308，热缩管308的一端热缩在一根主转接光缆310上，另一端热缩在筒状凸起部303上，从而将一根主转接光缆310密封地固定到筒状凸起部303上。
在本发明的一个实例性的实施例中，如图4所示，在基座301的第二端的内壁上形成有一个第一卡槽304；光缆扇出器300还包括一个保持块306，用于将多根分支转接光缆320保持在一起；并且该保持块306适于卡持在第一卡槽304中，从而能够将多根分支转接光缆320固定到壳体的基座301上。
在本发明的一个实例性的实施例中，如图4所示，光缆扇出器300还包括一个应力缓冲靴307，应力缓冲靴307套装在多根分支转接光缆320上，以防止多根分支转接光缆320由于侧向拉力的作用而受损。
在本发明的一个实例性的实施例中，如图4所示，在基座301的第二端的内壁上还形成有一个第二卡槽305；并且在应力缓冲靴307上形成有一个块状凸缘部3071，该块状凸缘部3071卡持在第二卡槽305中，从而将应力缓冲靴307固定到壳体的基座301上。
本领域的技术人员可以理解，上面所描述的实施例都是示例性的，并且本领域的技术人员可以对其进行改进，各种实施例中所描述的结构在不发生结构或者原理方面的冲突的情况下可以进行自由组合。
虽然结合附图对本发明进行了说明，但是附图中公开的实施例旨在对本发明优选实施方式进行示例性说明，而不能理解为对本发明的一种限制。
虽然本总体发明构思的一些实施例已被显示和说明，本领域普通技术人员将理解，在不背离本总体发明构思的原则和精神的情况下，可对这些实施例做出改变，本发明的范围以权利要求和它们的等同物限定。
应注意，措词“包括”不排除其它元件或步骤，措词“一”或“一个”不排除多个。另外，权利要求的任何元件标号不应理解为限制本发明的范围。
