Description

光缆扇出器
本申请要求于2015年1月7日递交中国专利局的、申请号为201520009100.0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
本发明涉及一种用于将一根主光缆分成多根分支光缆的光缆扇出器。
背景技术
在现有技术中，在需要将一根多芯主光缆分成多根分支光缆时，就需要提供一个光缆扇出器或光缆分裂器。主光缆从光缆扇出器的一端引入，多根分支光缆从光缆扇出器的另一端引出。
但是，在现有技术中，当分支光缆受到侧向拉力(与分支光缆的轴线方向垂直的拉力)时，分支光缆就会被折弯，对分支光缆造成损害，进而影响光信号传输，严重时甚至造成光信号中断。
为了解决前述问题，在现有技术，通常在光缆扇出器的引出分支光缆的一端上套装一个橡胶尾套(或称为应力缓冲靴)，分支光缆穿过该橡胶尾套。这样，当分支光缆受到侧向拉力时，橡胶尾套对作用在分支光缆上的侧向拉力有一个缓冲作用，使得分支光缆不会被过分弯折，极大地保护了分支光缆。尽管橡胶尾套能够保护分支光缆，提高了光通信的稳定性，但是也增加了成本。

图2显示图1所示的光缆扇出器的分解示意图。
具体实施方式
下面通过实施例，并结合附图，对本发明的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标号指示相同或相似的部件。下述参照附图对本发明实施方式的说明旨在对本发明的总体发明构思进行解释，而不应当理解为对本发明的一种限制。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
根据本发明的一个总体技术构思，提供一种光缆扇出器，用于将一根主光缆分成多根分支光缆。所述光缆扇出器包括壳体，所述壳体具有第一端和与所述第一端相对的第二端。所述主光缆从所述壳体的第一端引入，并且所述多根分支光缆从所述壳体的第二端引出。其中，在所述壳体的第二端处设置有一个分支缆保护部件，所述分支缆保护部件具有一个朝外逐渐扩大的喇叭状开口，所述多根分支光缆经由所述喇叭状开口引出到所述壳体的外部。
图1显示根据本发明的一个示例性的实施例的光缆扇出器的立体示意图；和图2显示图1所示的光缆扇出器的分解示意图。
在本发明的一个示例性的实施例中，公开了一种光缆扇出器，如图1和图2所示，该光缆扇出器用于将一根主光缆10分成多根分支光缆20。
如图1所示，在图示的实施例中，光缆扇出器100包括壳体100，该壳体100具有第一端(图1中的右端)和与第一端相对的第二端(图1中的左端)。主光缆10从壳体100的第一端引入，并且多根分支光缆20从壳体100的第二端引出。
在本发明的一个示例性的实施例中，如图1所示，在壳体100的第二端处设置有一个分支缆保护部件110，该分支缆保护部件110具有一个朝外逐渐扩大的喇叭状开口101，多根分支光缆20经由喇叭状开口101引出到壳体100的外部。
如图2所示，在图示的实施例中，喇叭状开口101具有光滑的弧形内表面101a，并且该弧形内表面101a的曲率半径大于分支光缆20所允许的最小弯曲半径。
这样，在分支光缆20受到侧向拉力时，分支光缆20就会接触喇叭状开口101的弧形内表面101a并沿弧形内表面101a平滑弯曲和均匀受力，不会出现过度折弯，从而能够有效地防止分支光缆20受到侧向拉力的损害。
在本发明的一个示例性的实施例中，如图1所示，分支缆保护部件110可以与壳体100形成一体。例如，分支缆保护部件110和壳体100可以一起模制而成，这样能够降低成本。
在本发明的另一个示例性的实施例中，分支缆保护部件110可以为组装到壳体100上的一个独立部件。
如图2所示，在本发明的一个示例性的实施例中，光缆扇出器还包括一个保持块21，多根分支光缆20的一端被固定在保持块21中。
请继续参见图2，在壳体100的内壁中形成有一个凹槽102，保持块21适于被卡持在该凹槽102中，从而将多根分支光缆20固定至壳体100。
在本发明的一个示例性的实施例中，如图1和2所示，在壳体100的第一端处形成有一个朝外凸出的凸起部120，并且光缆扇出器还包括一个热缩管11，该热缩管11热缩在凸起部120和主光缆10的一端上，从而将主光缆10固定至壳体100。
如图2所示，在本发明的一个示例性的实施例中，壳体100包括第一半壳体100a和第二半壳体100b。第一半壳体100a和第二半壳体100b被构造成能够相互组合在一起，以形成一个完整的壳体。
在图示的实施例中，如图2所示，分支缆保护部件110包括形成在第一半壳体100a上的第一半体110a和形成在第二半壳体100b上的第二半体110b，并且第一半体110a和第二半体110b被构造成能够相互组合在一起，以形成一个完整的分支缆保护部件110。
如图2清楚地显示，在本发明的一个示例性的实施例中，在第一半体110a和第二半体110b中的一个半体110b的两侧分别形成有第一弹性卡钩111；并且在第一半体110a和第二半体110b中的另一个半体110a的两侧分别形成有与第一弹性卡钩111对应的第一卡槽112。这样，当第一半体110a和第二半体110b组合在一起时，第一弹性卡钩111卡扣到第一卡槽112中，从而将第一半体110a和第二半体110b锁定在一起。
如图2清楚地显示，在本发明的一个示例性的实施例中，在第一半壳体100a和第二半壳体100b中的一个半壳体100b的两侧分别形成有第二弹性卡钩104；并且在第一半壳体100a和第二半壳体100b中的另一个半壳体100a的两个侧壁上分别形成有与第二弹性卡钩104对应的第二卡槽108。这样，当第一半壳体100a和第二半壳体100b组合在一起时，第二弹性卡钩104卡扣到第二卡槽108中，从而将第一半壳体100a和第二半壳体100b锁定在一起。
请继续参见图2，在图示的实施例中，在第一半壳体100a和第二半壳体100b中的另一个半壳体100a中形成有插孔106，每个插孔106从另一个半壳体100a的侧壁的 顶面一直延伸至对应的第二卡槽108。每个第二弹性卡钩104穿过对应的插孔106并卡扣到对应的第二卡槽108中。由于第二弹性卡钩104的弹性臂部容纳在插孔106中，因此，可以防止第二弹性卡钩104的弹性臂意外地受到外力的作用而使得第二弹性卡钩104与第二卡槽108分离。
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。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。
