本申请要求于2015年3月18日递交中国专利局的、申请号为201510119797.1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

在现有技术中,防尘帽主要有以下两种技术方案:(1)在智能光纤管理系统中,光纤适配器的防尘帽采用透明材质制成,这样,透过该防尘帽可以看到设置在光纤适配器底部上的指示灯的工作状况;(2)在常规的光纤适配器中,光纤适配器采用黑色(不透明)或者深色(半透明)的材质制成,这样,安装在光纤适配器的跳线端的跳线光纤连接器发出的激光就不能透射到光纤适配器的用户端,从而能够避免对人眼造成损伤。
对于前述现有的技术方案,如果防尘帽使用透光材质制成,人眼能够观察到设置在光纤适配器的底部的指示灯的工作状态,但是,在使用透光材质的防尘帽时,从光纤适配器另一端的跳线光纤发出的激光就透过防尘帽,从防尘帽的外端面输出,因此,使用透光材质的防尘帽不能防止从光纤适配器另一端透射过来的激光,容易损伤人眼。如果采用黑色或深色材质的防尘帽,可以阻止从光纤适配器的另一端透射过来的激光,但人眼不能看到指示灯的工作状态。
此外,在前述现有技术方案中,即使防尘帽使用透光材质制成,由于指示灯发出的光纤散射到各个方向,因此,在室外太阳光的环境下,人眼也难以清楚地或容易地看出指示灯的工作状态。

如图1至图4所示,在本发明的一个实例性的实施例中,在防尘帽200的内部设置有一个反射面212。当防尘帽200装配到光纤适配器100的一个端口 101中、且跳线光纤连接器300插入光纤适配器的100的另一个端口102中时:(i)从指示灯112发射出的光线L1入射在反射面212的一侧(图4中的左侧)上,被反射面212反射向防尘帽200的外端部230,并从防尘帽200的外端部230输出;并且(ii)从跳线光纤连接器300的跳线光纤330发射出的激光L2入射在反射面212的另一侧(图4中的右侧)上,被反射面212反射向防尘帽200的侧部,并从光纤适配器100的侧部输出。
在本发明的一个实例性的实施例中,如图4所示,当防尘帽200装配到光纤适配器100的一个端口101中时,反射面212与光纤适配器100的轴线成大于零度且小于90度的夹角β。
在本发明的另一个实例性的实施例中,如图4所示,当防尘帽200装配到光纤适配器100的一个端口101中时,反射面212与光纤适配器100的轴线成大于30度且小于60度的夹角β。
在图4所示的实施例中,当防尘帽200装配到光纤适配器100的一个端口101中时,反射面212与光纤适配器100的轴线成45度的夹角β。这样,从跳线光纤连接器300的跳线光纤330发射出的激光L2能够被沿与光纤适配器100的轴线垂直的方向输出到光纤适配器100的外部。
在实际应用时,光纤适配器100一般以高密度、成排地安装在光纤连接箱中,在光纤适配器100的侧部仅留有很狭窄的缝隙,因此,在插拔跳线光纤连接器300时,操作人员的眼睛只能从光纤适配器100或防尘帽200的外端部来观察光纤适配器100的指示灯。在本发明的前述实施例中,从指示灯112发射出的光线L1从防尘帽200的外端部230输出,因此,人眼可以在防尘帽200的外端部230处清楚地看到指示灯112的工作状态。此外,从跳线光纤连接器300的跳线光纤330发射出的激光L2从光纤适配器100的侧部输出,而不会从防尘帽200的外端部230输出,因此,操作人员的眼睛不可能看到从光纤适配器100的侧部输出的激光,因此,可以有效地防止从跳线光纤330发出的激光对人眼造成伤害。
如图3所示,在图示的实施例中,跳线光纤连接器300包括一个光纤插芯320,跳线光纤330容纳在光纤插芯320中。
如图1和图4所示,在本发明的一个实例性的实施例中,防尘帽200的外端部230具有一个光输出面(或称为光输出窗口)230a,从指示灯112发射出的光线L1从光输出面230a输出。
在图示的实施例中,如图4所示,光输出面230a与光纤适配器100的轴线垂直。
如图1、图2和图4所示,在图示的实施例中,防尘帽200具有适于插入并保持在光纤适配器100的一个端口101中的插入部210。反射面212形成在防尘帽200的插入部210中。
如图1、图2和图4所示,在本发明的一个实例性的实施例中,在防尘帽200的插入部210的底部形成有一个空腔211,反射面212构成空腔211的一个倾斜的壁面。
如图1、图2和图4所示,在本发明的一个实例性的实施例中,防尘帽200具有位于插入部210和外端部230之间的凸缘部220;并且当防尘帽200装配在光纤适配器100的一个端口101中时,凸缘部220抵靠在光纤适配器100的一个端口101的外端面上,从而提高对光纤适配器100的密封性。
如图1、图2和图4所示,在图示的实施例中,指示灯112为LED灯。指示灯112设置在光纤适配器100的底壁上。
在本发明的另一个实例性的实施例中,还公开了一种光纤连接组件。如图1至图4所示,该光纤连接组件主要包括光纤适配器100、前述防尘帽200和跳线光纤连接器300。
如图1至图4所示,在图示的实施例中,光纤适配器100具有第一端口101和与第一端口101相对的第二端口102,并且在第一端口101处设置有一个指示灯112。防尘帽200装配到光纤适配器100的第一端口101中,用于密封第一端口101。跳线光纤连接器300插入到光纤适配器100的第二端口102中。
如图3所示,在图示的实施例中,在跳线光纤连接器300中设置有一个芯片310,在该芯片310中存储有跳线光纤330的身份信息。在光纤适配器100上设置有一个信号读取器111,该信号读取器111用于读取芯片310中存储的跳线光纤330的身份信息。这样,就可以将读取的跳线光纤330分配给指定的用户端,从而能够提高光纤互连效率,而且能够防止将跳线光纤330连接到错误的用户端。
在本发明的一个实例性的实施例中,如图1所示,信号读取器111和指示灯112安装在同一个电路板110上;并且该电路板110安装在光纤适配器100的底面上。
在本发明的一个实例性的实施例中,由于从跳线光纤连接器300发射出的激光L2被反射面212反射向光纤适配器100的侧壁,而不会从防尘帽200的外端部230输出,因此,即使防尘帽200和光纤适配器100都由透明材料制成,从跳线光纤连接器300发射出的激光L2也不会对人眼造成伤害。
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。
