如图1-图3所示，一种Ttap型防水连接器组件，包括SC连接器100，SC连接器100的外侧套设有防水内壳200，防水内壳200的外侧套设有防水外壳300。SC连接器100的前端设置有端帽400，防水外壳300前端上设置外螺纹，端帽400上设置内螺纹，防水外壳300前端与端帽400螺纹连接。SC连接器100的后端设置有连接件500，防水外壳300后端设置有内螺纹，连接件500前端设置有外螺纹，防水外壳300与连接件500螺纹连接。防水内壳200后端设置有外螺纹，连接件500前端设置有内螺纹，防水内壳200与连接件500螺纹连接。SC连接器100设置在光缆的端部，用于光缆的外部连接，SC连接器100朝向光缆端口的一端为本年实施例中所提到的前端，另一端即为后端。连接件500上设置有抵在防水为外壳端部的防水圈510，连接件500远离防水内壳200的一端通过螺纹连接有防水尾帽600，该防水尾帽600固定在光缆外皮上，连接件500的后端设置外螺纹，防水尾帽600的前端设置内螺纹，防水尾帽600与光缆外皮的固定方式可以用胶水也可以用注塑或是其它能使二者固定的现有技术，防水尾帽600与连接件500之间设置有防水帽610，增加防水性能。
在SC连接器100的外侧层层套设的防水内壳200和防水外壳300，并在防水外壳300的前端和后端分别通过设置端帽400和防水圈510实现防水外壳300的端部密封，从而实现对光缆端部连接的防水防尘。端帽400和防水外壳300、连接件500和防水内壳200与防水外壳300均通过螺纹连接，不仅能够防水，而且拆卸和连接非常方便。使该防水连接器组件在光缆连接现场组装成为可能，且整体结构简单，操作方便，防水性能强，保证信号传输得到稳定性。
本实施例部分内螺纹与外螺纹在图中未示出。
防水内壳200包括头部210和管部220，头部210朝向SC连接器100的前端，管部220连接在头部210朝向SC连接器100的一侧。在头部210内侧壁上开设有一导向槽710，该导向槽710沿防水内壳200的长度方向开设，这个导向槽710与设置在SC连接器100外壁的导向条720相互配合，用于定位。在安装时，将防水内壳200从SC连接器100后端插入，并且使导向条720滑入导向槽710中，为防水内壳200和SC连接器100的连接提供导向作用。并且当导向条720抵触到导向槽710的端部时，表明防水内壳200已经插入到能够移动的最大位置，即已经和SC连接器100连接好。
到导向槽710尾部通过一倾斜面从头部210内壁向管部220内壁过渡，该倾斜面的尾部落在管部220内壁上。这个倾斜面使得导向条720能够很容易得滑入到导向槽710中，不会因为在同一截面存在过大的高度差，而抵住导向条720的移动。
在防水内壳200的外侧设置有密封圈230，防水外壳300从防水内壳200的前端插入，当防水外壳300的后端抵触在防水圈510上时，密封圈230 处于防水外壳300的前端，填充了该位置上防水外壳300与防水内壳200的间隙，起到了防水外壳300前端防水防尘的效果。密封圈230为环状，密封圈230的外径与防水外壳300的内径一致，使密封圈230能从防水外壳300穿过，又尽可能减小间隙，实现防水密封。
防水外壳300的的外侧壁上设置有防滑纹900，在安装防水外壳300时提供手指捏握的摩擦力。
防水尾帽600的中部设置有螺纹圈800，在防水连接器组件安装时提供缓冲力，也为光缆连接部位的弯折提供缓冲保护。
SC连接器100内部开设的线孔孔径在5mm-6mm之间，本实施例取用5mm，使该SC连接器100能够适应不同直径的光缆线材。本实施例所用的SC连接器100可以是市场上普通的SC连接器100，不需要特制，这扩大了本实施例的使用范围，拓展了应用场景。线材从SC连接器100的尾部穿入，并通过锁紧螺栓910锁在SC连接器100的尾部，使SC连接器100固定在线材上。
现场组装过程：SC连接器100包裹设置在光缆端部，将防水尾帽600穿入并固定在光缆端部，然后将连接件500从SC连接器100前端插入，并螺纹连接在防水尾帽600上；然后将防水内壳200从SC连接器100前端插入，并螺纹连接在连接件500的前端；再将防水外壳300从SC连接器100前端插入，并螺纹连接在连接件500的前端，使防水外壳300的后端抵触在防水圈510上，此时，密封圈230位于防水外壳300前端；最后再将端帽400螺纹连接在防水外壳300上，完成组装。整个组装过程方便快捷，防水效果好。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
