Description

一种光纤接头及光背板 技术领域
本申请涉及但不限于一种光纤接头。
背景技术
相关技术的光纤电路背板结构为光纤埋入背板后，通过光纤接头拉出背板，线卡与背板之间通过同种型号的光纤接头进行对接。将线卡插到光背板上，线卡中的光纤插头和背板上的光纤接头对接咬合，即可实现背板光互联。但是，在背板与线卡未对接时，该背板光纤接头会长期裸露，灰尘等异物不可避免的进入接头内部，容易致使光纤接头毁坏和污染，影响光纤传导信号质量，使设备无法正常稳定的工作。现基本采用手动安装接头上的保护装置，但这种方法存在安装麻烦、不易操作、维修不便等缺点。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本文提供一种便于安装、无需手动、易于维修、能够保护光纤清洁、提高光纤传输效率的光纤接头。
一种光纤接头，包括光纤、包裹光纤的保护壳，所述保护壳的一端设置为与光背板连接，所述保护壳的另一端的端口设置有保护机构，其中，所述保护机构在所述光纤被闲置的情况下处于关合状态，以及在所述光纤被使用的情况下处于开启状态。
可选的，所述光纤接头的保护机构包括：保护盖和连接所述保护盖和所述保护壳的弹性部件。
可选的，所述光纤接头在关合状态下，所述保护盖设置在与所述端口平行的平面上；在开启状态下，所述保护盖受插入的光纤插头的挤压，而绕所 述弹性部件与所述保护壳的连接点摆至所述端口内部，以使所述光纤插头与所述光纤接头密合。
可选的，所述弹性部件为弹簧。
可选的，所述弹性部件为弹性塑料。
可选的，所述弹性部件为弹性橡胶。
可选的，所述保护盖与所述弹性部件为一体成型结构。
根据本发明实施例，使用保护壳与保护盖将光纤接头保护起来，既可实现保护光背板上光纤接头的清洁性，又方便工程安装，可以提高光纤的传导速率。
在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述
图1为本发明实施例中光纤插头与光纤接头未对接时，保护盖处于闭合状态下的结构示意图。
图2为本发明实施例中光纤插头与光纤接头已插入对接状态下的保护盖朝内侧斜下方打开的结构示意图。
图3为本发明实施例中光纤插头与光纤接头在对接状态下保护盖朝内侧贴合保护壳打开的结构示意图。

本发明的实施方式
下面结合附图和实施例对本发明进行详细说明。
如图1所示，本发明实施例的光背板1上光纤6的保护装置，设置有光背板1、光纤6、保护壳2、保护机构3、弹性部件4、保护盖5、光纤插头7、线卡8。
光背板1垂直连接有光纤6，线卡8上垂直连接有光纤插头7，光背板1上的光纤6外侧包裹有保护壳2，光纤6的一端与光背板1垂直连接，与另一端平行设置有保护机构3，其中，保护机构3在光纤6被闲置的情况下处于关合状态，使光纤接头内部的光纤6与外部环境隔离，避免受外界环境影响。当在光纤6被使用的情况下保护机构3处于开启状态，光纤6与光纤插头7呈咬合对接状态。
该保护机构3包括弹性部件4和保护盖5，保护盖5通过弹性部件4与保护壳2相连接。当光背板1中光纤6与线卡8中光纤插头7未连接时，保护盖5成关闭状态，平行于光纤6的另一端口，可以起到保护光纤6的清洁、防尘进入污染光纤6。
当线卡8中光纤插头7与光背板1上的光纤6插入咬合对接时，通过机械用力使保护盖5打开，保护盖5绕弹性部件4与保护壳2的连接点摆至所述端口内部，以使所述光纤插头7与所述光纤6实现密合对接，如图2。
本发明实施例的另一实施方案为保护盖4不限于向内斜下方打开方式，还可以采用向内侧紧贴保护壳2打开，如图3。
弹性部件4可以是弹簧，或者是橡胶、塑料类的弹性材料，在机械外力作用下可以发生弹性形变、自动开合，在外力消失后又可以恢复原状。
工业实用性
根据本发明实施例，使用保护壳与保护盖将光纤接头保护起来，既可实现保护光背板上光纤接头的清洁性，又方便工程安装，可以提高光纤的传导速率。
