光纤连接器组件及其插头
技术领域
本发明涉及一种壳体内设置有 DLC插头模块的光纤连接器组件， 同时本 发明还涉及该连接器组件的插头。
背景技术
在光信号的传输领域， DLC插头模块使用较多， DLC插头模块包括插头 部分， 插头部分的尾端连接设置有光缆， DLC插头模块既可用于传输光信号， 但是， 无法承受来自光缆的拉力， 这就需要在光模块的外侧套装上壳体形成光 纤连接器， 并将光缆的芳纶纤维浇注在粘结套上， 粘结套的内孔一般为阶梯孔 或是内孔壁为锥面， 在粘结套的内孔的扩口端灌注胶液体将光缆的芳纶纤维浇 注在粘结套上形成抗拉结构， 粘结套的外周面为阶梯轴， 粘结套外周面上的台 阶与连接器壳体的内孔上设置在阶梯面挡止配合将来自光缆的拉力传递给连 接器壳体， 保护 DLC插头部分不受力的作用。 由于 DLC插头模块在和适配的 光模块对插时是通过双卡子对接的，在将两者分离时需要捏压双工卡子使 DLC 插头模块在和适配的光模块分离， 那么， 同样， 在将 DLC光纤连接分离时也 必须先捏压双工卡子使 DLC插头模块再和适配的光模块分离， 也就说明不能 同时将连接器壳体和适配光模块的壳体以及 DLC插头模块和适配的光模块同 时分离， 因此， 现有技术中都是将连接器壳体与 DLC插头模块设计成可相对 滑动的，粘结套与连接器壳体滑动配合并通过粘结套外周的台阶面与连接器壳 体内孔的台阶面防脱配合， 在连接器与适配连接器分离时先将光纤连接器的壳 体与适配连接器的壳体分离，然后将连接壳体相对于 DLC光模块后移，使 DLC 光模块由连接器壳体的内孔中露出， 然后捏压双工卡子再将 DLC光模块与适 配光模块分离， 这种光纤连接器的结构简单， 连接器外壳体只起到承担拉力的 作用，在连接器体与适配连接器插接和分离时都需要分两步进行，很浪费时间， 无法实现光纤连接器与适配连接器的快速插拔。

所述的内壳体外侧间隙设置有同心套筒， 同心套筒通过其后端与内壳体一 体设置，所述一个以上的弹性爪均匀设置在同心套筒的周壁上并由设置在同心 套筒外周壁上的 U形的径向贯通槽分割而成，所述一个以上的弹性爪通过同心 套筒的后端形成一个整体，所述同心套筒上于条状凸起处设置有延伸至前端面 的 U形缺口。

所述的内壳体外侧间隙设置有同心套筒， 同心套筒通过其后端与内壳体一 体设置， 所述一个以上的弹性爪均匀设置在同心套筒的周壁上并由设置在同心 套筒外周壁上的 U形的径向贯通槽分割而成，所述一个以上的弹性爪通过同心 套筒的后端形成一个整体，所述同心套筒上于条状凸起处设置有延伸至前端面 的 U形缺口。
所述外壳体上设置的朝向后端的台阶与所述内壳体上设置的朝向前端的 台阶面之间设置有复位弹簧。
所述内壳体内设置有 DLC插头模块， DLC插头模块的后端连接有光缆， DLC插头模块穿设在固定板的定位孔中， 固定板的前端面与 DLC插头模块挡 止配合， 固定板的后端面与套装在光缆上的压接套挡止配合。
所述固定板的板面上设置有由固定板的外周面延伸至定位孔的光纤嵌入 槽。
本发明的连接器组件的插头的内壳体的外周面上设置有朝向前端的弹性 爪， 弹性爪的前端头上设置有锁块， 内壳体的周壁上径向滑动设置有浮动压块 在使用时，内壳体中配合设置有 DLC插头模块， DLC插头模块后端设置有光缆， 浮动压块的内端头压设在 DLC插头模块的双工卡子上， DLC插头模块可以通过 固定在其上的固定板滑动设置在内壳体的内孔中， 固定板的前端面与内壳体上 的内凸挡板的挡止配合， 固定板的后端面与内壳体后端设置的挡止台阶面通过 推压弹簧弹性配合， 内壳体的外周套装有外壳体， 外壳体上具有锁孔， 弹性爪 的锁块设置在锁孔中， 锁块凸出于内壳体的外周面， 浮动压块的外端头与内壳 体的内周面顶压配合， 外壳体的内孔周面上设置有在外壳体后移时推压浮动压 块的条状凸起。 当本发明的插头与插座插合时， 可用手握住外壳体， 外壳体通 过锁孔与锁块之间的配合带动内壳体， 内壳体通过推压弹簧与固定在 DLC插头 模块上的固定板带动 DLC插头模块一起向插座移动， DLC插头模块遇到插座内 的 DLC插座模块后在弹簧力的作用下与其配合插接， 同时， 外壳体的前端进入 插座壳体前端的开口， 弹性爪的锁块与插座壳体的锁紧槽配合实现插头和插座 的可靠插合， 插头壳体与插座壳体的插合和 DLC插头模块与插座内的 DLC插座 模块的插合同时进行， 不需要分两步进行插合； 在插头和插座分离时， 握住外 壳体使外壳体相对于内壳体后移， 这时， 外壳体上的条状凸起向内推压浮动压 ±夬， 浮动压块挤压双工卡子， 随着插头的移动， DLC插头模块与插座内的 DLC 插座模块分离， 同时， 外壳体的锁孔的侧壁挤压弹性爪的锁块使弹性爪收缩， 弹性爪的锁块与插座壳体的锁紧槽脱离实现插头壳体与插座壳体的分离，插头 壳体与插座壳体的分离和 DLC插头模块与插座内的 DLC插座模块的分离同时 进行， 不也需要分两步进行插合， 从而实现了插头、 插座的快速插拔。
