外壳体尾部可以为一弹性材料制成的防水尾夹， 套设于光纤的外表面， 防水尾夹外旋紧有一螺帽， 使得防水尾夹与光纤固定在一起， 实现防水的功 能。
从以上可知， 本实施例中， 由于连接器与外壳体是分离的， 因此， 连接 器上的插芯在法兰盘所在圓面上的位置是可变的， 能够适应不同规格的光模 块上的插孔。 在安装过程中， 可以先通过连接器的插芯与光模块的插孔对接， 将连接着的连接器与光纤连接于光模块； 再将外壳体与法兰盘旋接在一起。 因此， 本实施例中的防水光纤连接器能够兼容不同规格的光模块。
实施例二、 实施例一中的防水光纤连接器， 由于光纤与外壳体的防水尾夹被螺帽固 定在一起， 所以若在更换防水光纤连接器的过程中， 不先^ ^开防水尾夹外的 螺帽， 而直接旋开外壳体并往外拔， 则会将连接器一起往外拔， 容易将连接 器拔坏。 而现实中， 维修人员往往与最初的安装人员不同， 维修人员若不知 道须先松开螺帽， 而直接旋开外壳体并往外拔， 则容易拔坏连接器。 为此， 本发明实施例提供防水光纤连接器的另一实施例。
下面结合图 3至图 14, 对本发明实施例中防水光纤连接器的另一实施例进 行伴细说明。
本发明实施例中， 定义将防水光纤连接器安装于通信设备之后， 指向通 信设备的方向为前， 背向通信设备的方向为后。
如图 3至图 5所示， 防水光纤连接器包括法兰盘 20和线端连接器 30, 线端 连接器 30包括外壳体 31、 内壳体 32、 光纤 33以及与光纤 33连接的连接器 34, 连接器 34的头部有两个可与光模块上的插孔对接的插芯 341。
如图 6所示， 法兰盘 20的前端面上有凸起的套筒 21 , 套筒 21的内表面设有 第一紧固结构 211 ; 如图 4、 图 5和图 8所示， 外壳体 31的前部的外表面设有可 与第一紧固结构 211配合的第二紧固结构 311 , 结合图 3可知， 法兰盘 20与外壳 体 31通过第一紧固结构 211与第二紧固结构 311旋接。
如图 5和图 9所示， 内壳体 32呈可套设光纤 33与连接器 34的筒状； 外壳体 31呈可套设内壳体 32的筒状， 内壳体 32套设于外壳体 31的筒内， 光纤 33与连 接器 34套设于内壳体 32的筒内。 内壳体 32包括体部 321和连接于该体部 321后 端的防水尾夹 322, 内壳体 32的体部 321和外壳体 31均采用硬质材料制成。 防 水尾夹 322采用弹性材料制成， 有一可让光纤 33穿过的孔 3221 , 光纤 33穿过该 防水尾夹 322。
如图 6和图 9所示， 法兰盘 20的套筒 21的前端的内表面设有至少一个用于 阻挡内壳体 32的第一凸起 212 , 内壳体 32的体部 321的前端顶在第一凸起 212 上。
如图 7所示， 内壳体 32的防水尾夹 322包括塞入内壳体 32的体部 321的胶塞 3222, 以及露在内壳体 32的体部 321外面的尾夹部分 3223。
如图 9所示， 外壳体 31的内壁的尾部从前往后渐小， 防水尾夹 322被该尾 部向内挤压， 使得防水尾夹 322与光纤 33固定在一起， 从而实现防水功能。 下面结合图 10至图 13 , 对本发明实施例中的防水光纤连接器的安装方法 进行详细说明。
将本发明实施例中的防水光纤连接器安装于通信设备的过程包括： 101、 将法兰盘 20装于通信设备 40的外壳表面的对应于光模块 50的位置 上；
如图 10所示， 执行步骤 101之后， 法兰盘 20的套筒 21被安装在通信设备 40 内， 光模块 50从套筒伸出。
102、 将连接着的光纤与连接器套设于内壳体内， 将内壳体套设于外壳体 内， 从而完成线端连接器的组装；
执行步骤 102之后的整体结构如图 11所示。 图 11中， 包括光模块 50、 安装 在通信设备 40上的法兰盘 20 , 以及组装好的线端连接器 30。
103、 将连接器 34的两个插芯与光模块 50的两个插孔对接；
如图 12所示， 执行步骤 103之后， 线端连接器 30上的连接器 34与通信设备 40上的光模块 50对接在一起。
此处需要说明的是， 步骤 101、 102与 103没有必然的先后顺序。
104、 将内壳体与外壳体的前部插入法兰盘的套筒内， 并通过外壳体的第 二紧固结构与法兰盘的第一紧固结构， 将外壳体的前部与法兰盘的套筒旋紧， 使得内壳体的前端顶在法兰盘的前端的第一凸起上， 以及外壳体的尾部向内 压紧防水尾夹， 至此， 完成防水光纤连接器的安装。
如图 13所示， 执行步骤 104之后， 线端连接器 30固定在通信设备 40上。 在步骤 104中， 将内壳体 32套设于外壳体 31的筒内， 通过第一紧固结构与 第二紧固结构， 旋紧外壳体 31的前部与法兰盘 20的套筒， 使得内壳体 32的前 端顶在法兰盘 20的前端的第一凸起上， 外壳体 31相对防水尾夹 322前移， 由于 外壳体 31的内壁的尾部从前往后渐小， 使得在外壳体 31相对防水尾夹 322前移 的过程中， 外壳体 31的尾部向内压紧防水尾夹 322, 将防水尾夹 322与光纤 33 固定在一起， 从而实现防水的效果。 如图 9所示， 在旋紧外壳体 31的前部与法 兰盘的套筒之后， 防水尾夹 322的尾夹部分 3223的后部分 3225被外壳体 31往内 挤压的程度较大， 而前部分 3224被外壳体 31往内挤压的程度较 'J、。 从以上可知， 本实施例中， 防水尾夹在内壳体上， 是通过将外壳体与法 兰盘旋接在一起， 使得外壳体压紧内壳体的防水尾夹， 将防水尾夹与光纤固 定在一起， 因此， 在更换防水光纤连接器的过程中， 若直接旋开外壳体并往 外拔， 由于旋开外壳体的同时， 外壳体相对内壳体的防水尾夹后移， 而外壳 体的内壁的尾部从前往后渐小， 使得在旋开外壳体的过程中， 外壳体松开防 水尾夹， 防水尾夹与光纤分离开， 外壳体与光纤也分离开。 因此， 在更换防 水光纤连接器的过程中， 可以直接旋开外壳体并往外拔， 而不会将连接器一 起往外拔， 可以避免拔坏连接器。
此外， 由于在将外壳体与法兰盘旋紧的过程中， 外壳体的转动会带动内 壳体的转动， 而内壳体尾部的防水尾夹的转动又会带动光纤的扭转， 从而导 致光纤与连接器的交界处容易被扭断。 为解决这个问题， 可选地，如图 6所示， 法兰盘 20的套筒 21前端设有至少两个第一凸起 212; 并且， 如图 7所示， 内壳 体 32的前端设有至少一个第二凸起 323 , 第二凸起 323可与相邻两个第一凸起 212形成的凹槽 213相配合。 并且， 在步骤 104中， 将内壳体 32的前部插入法兰 盘 20的套筒 21内时， 将第二凸起 323插入凹槽 213 , 使得内壳体相对于法兰盘 固定， 而不会随着外壳体的转动而转动， 从而防止光纤 33与连接器 34的交界 处被扭断。
可选地， 如图 9所示， 内壳体 32的防水尾夹 322与外壳体 31的尾部相切， 内壳体 32的体部 321与外壳体 31也相切， 结合图 7 , 内壳体 32的中部设有第一 防水圈 324, 以实现更好的防水效果。
可选地， 如图 14所示， 法兰盘 20的套筒 21的前端的内表面、 法兰盘 20的 套筒 21的后端的外表面均设有第二防水圈 214, 以实现更好的防水效果。
可选地，如图 4和 5所示，光纤 33上设有一用于阻挡外壳体的阻挡结构 331 , 阻挡结构可以为光纤上凸出的圓环结构或其它结构， 以使得在安装防水光纤 连接器的过程中， 外壳体不会无止境地往光纤后部滑动。
此处需要说明的是， 现有技术中， 法兰盘的套筒相对通信设备外凸， 而 通信设备内的光模块贴设于通信设备的外壳， 当要现场徒手更换光模块时， 需要将手指伸入法兰盘的套筒前端， 掰下光模块的把手， 将光模块拖出， 但 是， 法兰盘的套筒大小通常根据光模块的大小设定， 无法容纳两个手指， 因 此， 被法兰盘的套筒所挡， 无法徒手更换光模块。
如图 10所示， 本发明实施例中， 法兰盘 20的套筒 21相对通信设备内凹， 光模块相对套筒向通信设备外伸出， 因此， 当徒手更换光模块时， 不会被法 兰盘的套筒所挡。 由此可见， 本发明实施例相对现有技术， 还具有能够徒手 更换光模块的优点。
可以理解的是， 法兰盘的套筒也可以设置在法兰盘的后端面上， 这种情 况下， 可以在套筒的内表面或外表面设有第一紧固结构， 并在外壳体的前部 的相应表面设置可与第一紧固结构配合的第二紧固结构。
从以上可知， 本发明实施例的防水光纤连接器中， 由于光纤与外壳体是 分离的， 因此， 同于实施例一， 具有能够兼容不同规格的光模块的优点。 并 且， 本实施例中， 防水尾夹在内壳体上， 是通过将外壳体与法兰盘旋接在一 起， 使得外壳体压紧内壳体的防水尾夹， 将防水尾夹与光纤固定在一起， 因 此， 在更换防水光纤连接器的过程中， 可以直接旋开外壳体并往外拔， 而不 会将连接器一起往外拔， 可以避免拔坏连接器。
本发明实施例还提供一种室外通信设备， 包括能够实现上述功能的防水 光纤连接器。
以上对本发明实施例所提供的防水光纤连接器及室外通信设备进行了详
例的说明只是用于帮助理解本发明的核心思想； 同时， 对于本领域的一般技 术人员， 依据本发明的思想， 在具体实施方式及应用范围上均会有改变之处， 综上所述， 本说明书内容不应理解为对本发明的限制。
