Description

一种用于安装光缆的接头盒以及方法 技术领域
本发明涉及通信器材，尤其涉及的是一种用于安装光缆的接头盒以及方法。
背景技术
由于光纤通信具有大容量、长距离和抗电磁干扰等优点，因此更加迎合未来人类对信息量大，精密度高的需求，而且低廉的价格使得光纤这种传输介质能得到很大范围的推广，目前光纤网络已经逐步进入家庭使用，即光纤到户(英文全称：Fiber To The Home，英文简称：FTTH)。在FTTH工程中，作为连接用户和网络的重要接入设备，用于安装光缆的接头盒被越来越广泛的应用到FTTH技术中。
以下结合图1所示进行说明，其中，图1为现有技术所示的光纤到户网络示意图。如图1所示，中心机房101进行光电信号的转换，并将转换后的信号发射给接头盒102，所述接头盒通过入户光缆103将信号发送给用户终端盒104，从而实现光纤到户。
为实现接头盒的密封，则将光缆塞入接头盒的安装孔后，在光缆和安装孔之间套上一个带胶的热缩管，然后用高温的热风枪吹所述热缩管直至所述热缩管融化，从而使得融化后的所述热缩管缩小，并包紧光缆，从而使得所述光缆和所述安装孔之间没有间隙，从而密封所述接头盒。
但是，采用现有技术的所示的融化热缩管进行密封的方式所带来的弊端为：需要采用专用的工具，例如热风枪以及用于为所述热风枪供电的电源设备，而在具体施工过程中，寻找能够为热风枪供电的供电设备比较困难，而且通过热风枪对安装有一个热缩管的安装孔进行处理大致需要的时长为20至30分钟，而接头盒上设置有多个安装孔，则密封处理过程中需要较长的时间，密封效率比较低，而且一旦安装孔密封完成，则安装孔不能够重复开启，要开启安装孔进行维修，只能从接头盒的外面连根剪断光缆，提升了维修的难度和费用，增加了光缆的耗损。
发明内容
本发明实施例提供了一种提升了安装效率且便于维修的接头盒以及方法。
本发明实施例第一方面提供了一种接头盒。

为实现对所述直通光缆的密封，则在装配的过程中，首先将所述楔形块609插入所述第一光缆进出孔501内部，且抵持在所述第一开口509与所述第二开口510之间，随后在所述直通光缆的所述第一连接部505上依次套入所述第一垫片607、所述第一弹性件605、所述第一垫片607、所述第一抵持件603以及所述第一螺母组件601，并在所述直通光缆的所述第二连接部506上依次套入所述第二垫片608、所述第二弹性件606、所述第二垫片608、所述第二抵持件604以及第二螺母组件602。
以下对上述各部件的具体结构进行说明。
首先结合图9至图14所示，对所述第一螺母组件601的具体结构进行说明。
本实施例所示的所述第一螺母组件601和所述第二螺母组件602的结构相同，本实施例以所述第一螺母组件601的结构进行示例性说明，所述第二螺母组件602的具体结构请参见所述第一螺母组件601的具体结构的说明，具体在本实施例中不做赘述。
所述第一螺母组件601包括相互拼接的第一子螺母701和第二子螺母702，且所述第一子螺母701和所述第二子螺母702的内周面设置有内螺纹段。
具体的，本实施例所示的所述第一螺母组件601整体结构呈中空的圆柱形结构，则用于拼接所述第一螺母组件601的所述第一子螺母701和第二子螺母702沿所述第一螺母组件601的径向方向的横截面呈半圆形结构。
需明确的是，本实施例以所述第一螺母组件601包括两个子螺母为例进行示例性说明，在具体应用中，所述第一螺母组件601也可由多个子螺母拼接而 成，即本实施例对用于拼接成所述第一螺母组件601的所述子螺母的具体数目不做限定。

为保障已相互扣合成一个完整的所述第一螺母组件601的结构的稳定性，避免所述第一子螺母701和所述第二子螺母702之间相互脱离，则贯穿所述第一子螺母701的端部的任意位置设置有至少一个第一通孔707。
贯穿所述第二子螺母702的端部设置有至少一个第二通孔708。
本实施例以第一通孔707和所述第二通孔708分别为两个为例进行示例性说明，需明确的是，本实施例对所述第一通孔707和所述第二通孔708的具体数目不做限定，只要所述第一通孔707和所述第二通孔708的数目相等，且当第一子螺母701和所述第二子螺母702相互扣合以形成完整的所述第一螺母组件601时，所述第一通孔707和所述第二通孔708同轴设置即可。

可选的，可在所述第一通孔707内直接设置所述内螺纹段，或可在所述第一通孔707内嵌入设置有螺母，以使所述螺钉709上所设置的外螺纹段螺纹连接至所述第一通孔707内所嵌入的螺母的内螺纹段上。
本种设置方式中，对所述第二通孔708的内周面是否设置内螺纹段不做限定。

通过本实施例所示的所述第一螺母组件601的具体结构，可使得所述第一螺母组件601的结构稳定，避免用于组合以形成所述第一螺母组件601的第一子螺母701和所述第二子螺母702相对滑动，从而使得组装而成的所述第一螺母组件601具有相当的强度和刚度，符合接头盒对直通光缆安装的扭力的要求。
还需明确的是，本实施例对所述第一子螺母701和所述第二子螺母702拼接以形成完整的所述第一螺母组件601的方式的说明为可选的示例，只要拼接以形成的所述第一螺母组件601能够套设在所述光缆上即可，例如所述第一子螺母701和所述第二子螺母702可通过喉箍抱紧的方式以形成完整的所述第一螺母组件601。
因在具体安装直通光缆的过程中，因直通光缆很长，在具体操作中，不可能让所述第一弹性件605以及所述第二弹性件606从直通光缆的一端套入，则以下对本实施例所示的所述第一弹性件605是如何套设在所述直通光缆的所述第一连接部505上的进行说明。
