实施例1
为实现光纤连接器与光收发器之间的可插拔连接，解决光收发器组装不便带来的光缆报废问题，本申请实施例提供了一种有源光缆组件，如图1-图5所示，主要包括第一光缆卡环100以及顺次连接设置的光纤连接器200、光口适配器300和光收发器400；其中，所述光口适配器300固定安装在所述光收发器400一端，所述光纤连接器200与所述光口适配器300之间为可插拔式连接。
需要说明的是，本申请实施例以靠近所述光纤连接器200的一端为后端，以靠近所述光收发器400的一端为前端进行描述，但并不用以限制本申请。
参考图3，所述光纤连接器200包括活动套件203以及从后到前顺次连接设置的尾套204、中间连接套205和插接头206。其中，所述插接头206的前端用于与所述光口适配器300耦合，后端与所述中间连接套205连接；所述活动套件203套在所述插接头206外侧，用于在所述插接头206插入所述光口适配器300后，防止所述插接头从所述光口适配器300中脱离，从而实现所述光纤连接器200与所述光口适配器300之间的紧固，且所述活动套件203可沿所述插接头206前后滑动。
结合图1-图4，所述中间连接套205的外侧设有退位槽，且所述退位槽与所述插接头206的后端连接。所述第一光缆卡环100套在所述退位槽上， 用于阻挡所述活动套件203向后滑动。当取下所述光缆卡环并使所述活动套件203向后滑动至所述退位槽处时，所述活动套件203的紧固作用失效，则所述插接头206可从所述光口适配器300中拔出。
下面结合附图，对所述有源光缆组件的插拔结构进行具体介绍：
结合图4和图5，所述光口适配器300的内侧设有向外伸出的弹性卡爪301，所述插接头206前端的外侧设有对应的卡槽2061。所述插接头206的外侧还设有弹簧槽，所述弹簧槽位于所述卡槽2061的后端，且所述弹簧槽内设有弹簧2062；所述活动套件203的内侧设有凸块2031，所述弹簧2062的前端与所述凸块2031的后端相抵接。所述中间连接套205上还设有位于所述退位槽后端的第一导向销201和第二导向销202，如图3所示，用于在所述活动套件203向后滑动至所述退位槽处时，对所述活动套件203进行限位，即所述活动套件203至多可向后滑动至所述第一导向销201和所述第二导向销202处。
结合图4，当所述插接头206的前端插入所述光口适配器300时，所述光口适配器300内侧的弹性卡爪301恰好与所述插接头206外侧的卡槽2061耦合连接，此时所述弹簧2062处于自然状态，所述活动套件203前端的侧壁挤压在所述弹性卡爪301外侧，可防止所述弹性卡爪301外张与所述卡槽2061脱离，实现所述光纤连接器200与所述光口适配器300之间的紧固。此时将所述第一光缆卡环100安装在所述光纤连接器200上所述活动套件203与所述尾套204之间的退位槽上，可有效阻挡所述活动套件203向后滑动，使得所述活动套件203前端始终围在所述插接头206的弹性卡爪301外侧，从而有效防止所述弹性卡爪301外张与所述卡槽2061脱离。
结合图5，当需要将所述光纤连接器200从所述光口适配器300中拔出时，需先将所述第一光缆卡环100从所述退位槽处取下，然后将所述活动套件203向后滑动，即向所述活动套件203施加如图5所示的外力F，所述 弹簧2062在所述凸块2031的作用下被压缩，所述活动套件203滑动至所述中间连接套205的退位槽处，使得所述活动套件203前端的侧壁逐渐脱离所述弹性卡爪301，此时所述光纤连接器200的插接头206可从所述光口适配器300中拔出。
下面继续结合附图，对所述第一光缆卡环100的结构进行具体介绍：
如图6所示，所述第一光缆卡环100为封闭环形结构，包括第一半环110和第二半环120，所述第一半环110和所述第二半环120组装后形成第一环心101，用于容置所述光纤连接器200的所述中间连接套205。其中，所述第一半环110的第一端(即图中左端)和所述第二半环120的第一端通过卡扣方式连接，所述第一半环110的第二端(即图中右端)和所述第二半环120的第二端通过卡扣方式连接。
继续结合图7和图8，所述第一半环110包括设于中间的第一横梁118以及分别位于所述第一横梁118两端的第一侧臂111和第二侧臂112。其中，所述第一横梁118内侧设有第一让位槽117，用于为所述光纤连接器200上的所述第一导向销201或所述第二导向销202让位。所述第一侧臂111的外侧设有第一凸台115和第一凹坑113，所述第二侧臂112的外侧设有第二凸台116和第二凹坑114。

实施例5
在上述实施例1-实施例4的基础上，本申请实施例进一步提供了一种有源光缆组件的组装方法，用于组装实施例1-实施例4中所述的有源光缆组件。如图20所示，组装方法主要包括以下步骤：

参考图1-图4，当所述插接头206的前端插入所述光口适配器300时，所述光口适配器300内侧的弹性卡爪301恰好与所述插接头206外侧的卡槽2061耦合连接；此时所述弹簧2062处于自然状态，所述活动套件203前端的侧壁挤压在所述弹性卡爪301外侧，可防止所述弹性卡爪301外张与所述卡槽2061脱离，从而实现所述光纤连接器200与所述光口适配器300之间的紧固。其中，所述光收发器400内部部件已预先组装完成。
步骤12，将所述第一光缆卡环100套在所述光纤连接器200上所述尾套204与所述活动套件203之间的退位槽上，阻挡所述活动套件203向后滑动。
继续参考图1-图4，当所述插接头206插入所述光口适配器300中实现耦合后，将所述光缆卡环安装在所述光纤连接器200上所述活动套件203与所述尾套204之间的退位槽上。
组装完成后的有源光缆组件如图1、图12和图17所示，此时当有向后的外力施加在所述光纤连接器200的活动套件203上时，因所述光缆卡环位于所述活动套件203后的所述退位槽中，可有效阻挡所述活动套件203向后滑动，如图4所示，使得所述活动套件203前端始终围在所述插接头206的弹性卡爪301外侧，从而有效防止所述弹性卡爪301外张与所述卡槽2061脱离。其中：
1)当采用实施例1中的第一光缆卡环100时，所述第一光缆卡环100 在所述退位槽上的安装步骤具体如下：
首先，将所述第一半环110从上方或下方套在所述光纤连接器200的退位槽上。其中，所述光收发器400的手柄为软胶材料，安装所述第一光缆卡环100时可将其掰弯让位，因此所述第一半环110从所述光纤连接器200上方和下方套入均可。
然后，将所述第二半环120从所述第一半环110对侧方向套在所述光纤连接器200的退位槽上，使所述第二半环120的所述第一卡勾123和所述第二卡勾124分别挤入所述第一半环110的所述第一凹坑113和所述第二凹坑114中，并分别与所述第一半环110的所述第一凸台115和所述第二凸台116扣合。如此即可将所述第一光缆卡环100套在所述退位槽上。
进一步地，如果有源光缆组件需要返修拆解，则具体拆卸步骤如下：

然后，将所述活动套件203向后滑动至所述退位槽处，将所述光纤连接器200从所述光口适配器300中拔出，以便对所述光收发器400开壳返修。具体操作如下：向所述活动套件203施加与所述光收发器400方向相反的力F，使所述活动套件203滑动至所述中间连接套205的退位槽处，如图5所示，则所述活动套件203前端的侧壁逐渐脱离所述弹性卡爪301，此时向后拉动所述光纤连接器200可使所述弹性卡爪301外张与所述光纤连接器200，进而将所述光纤连接器200从所述光口适配器300中拔出。将所述光纤连接器200拔出后，可以无需携带光缆即可方便地对所述光收发器400开壳返修。
2)当采用实施例2中的第二光缆卡环500时，所述第二光缆卡环500在所述退位槽上的安装步骤具体如下：

进一步地，如果有源光缆组件需要返修拆解，则具体拆卸步骤如下：
首先，将所述第二光缆卡环500从所述光纤连接器200的退位槽上取下。具体操作如下：用镊子等工具撬开所述第四半环520的所述第三卡勾524，使其脱离所述第三半环510的所述第三凸台515，然后将所述第二光缆卡环500从所述光纤连接器200上取下。
然后，将所述活动套件203向后滑动至所述退位槽处，将所述光纤连接器200从所述光口适配器300中拔出，以便对所述光收发器400开壳返修。具体操作过程可参考前面描述，在此不做赘述。
3)当采用实施例3中的第三光缆卡环600时，所述第三光缆卡环600在所述退位槽上的安装步骤具体如下：
首先，从所述第一弯勾603和所述第二弯勾604处掰开所述第三光缆卡环600，使所述安装口607变大。
然后，将已掰开的所述第三光缆卡环600从所述安装口607处套入所述光纤连接器200的退位槽上。安装完成后所述安装口607变为初始大小。
进一步地，如果有源光缆组件需要返修拆解，则具体拆卸步骤如下：

然后，将所述活动套件203向后滑动至所述退位槽处，将所述光纤连接器200从所述光口适配器300中拔出，以便对所述光收发器400开壳返修。具体操作过程可参考前面描述，在此不做赘述。
4)当采用实施例4中的第四光缆卡环700时，所述第四光缆卡环700在所述退位槽上的安装步骤具体如下：
首先，向所述第六横梁703和所述第七横梁704施加如图19所示的外力时，使所述第一弹性臂701和所述第二弹性臂702向外拉伸，使得所述第四环心变大。
然后，从所述尾套204方向将所述第四光缆卡环700套入所述光纤连接器200的退位槽处，再撤去外力使所述第四环心恢复初始大小，使得所述第四光缆卡环700卡在所述光纤连接器200的退位槽上。
进一步地，如果有源光缆组件需要返修拆解，则具体拆卸步骤如下：
首先，向所述第六横梁703和所述第七横梁704施加如图19所示的外力时，使所述第一弹性臂701和所述第二弹性臂702向外拉伸，使得所述第四环心变大，直至能将所述第四光缆卡环700从所述光纤连接器200取下，可从所述尾套204方向取下。

本申请实施例提供的上述方法中，光纤连接器可方便地插入和拔出安装在光收发器上的光口适配器，即光纤连接器与光收发器之间可实现可插 拔连接，使得光收发器的组装和拆解均无需携带光缆，操作方便高效，可解决光收发器组装不便带来的光缆报废的问题。
实施例6
为实现光纤连接器与光收发器之间的可插拔连接，进而解决光收发器组装不便带来的光缆报废问题，本申请实施例提供了一种有源光缆组件，与前述实施例-实施例4的区别在于，不再设置光缆卡环，而是通过可旋转的中间连接套来阻挡所述活动套件的向后滑动。
如图21所示，本申请实施例提供的有源光缆组件包括顺次连接设置的光纤连接器200、光口适配器300和光收发器400；其中，所述光口适配器300固定安装在所述光收发器400一端，所述光纤连接器200与所述光口适配器300之间为可插拔式连接。
参考图3，所述光纤连接器200包括活动套件203以及从后到前顺次连接设置的尾套204、中间连接套205和插接头206。其中，所述插接头206的前端用于与所述光口适配器300耦合，后端与所述中间连接套205连接；所述活动套件203套在所述插接头206外侧，用于在所述插接头206插入所述光口适配器300后，防止所述插接头从所述光口适配器300中脱离，从而实现所述光纤连接器200与所述光口适配器300之间的紧固，且所述活动套件203可沿所述插接头206前后滑动。
结合图21，所述中间连接套205的外侧设有退位槽，所述退位槽与所述插接头206的后端连接。所述中间连接套205可绕所述尾套204旋转，当所述中间连接套205绕轴旋转预设角度时，可阻挡所述活动套件203向后滑动。当所述中间连接套205处于初始位置时，无法阻挡所述活动套件203向后滑动，则所述活动套件203可向后滑动至所述退位槽处时，紧固作用失效，所述插接头206可从所述光口适配器300中拔出。
下面结合附图，对所述有源光缆组件的插拔结构进行具体介绍：
参考图22和图23，所述光口适配器300的内侧设有向外伸出的弹性卡爪301，所述插接头206前端的外侧设有对应的卡槽2061。所述插接头206的外侧还设有弹簧槽，所述弹簧槽位于所述卡槽2061的后端，且所述弹簧槽内设有弹簧2062；所述活动套件203的内侧设有凸块2031，所述弹簧2062的前端与所述凸块2031的后端相抵接。所述中间连接套205上还设有位于所述退位槽后端的第一导向销201和第二导向销202，如图3所示，用于在所述活动套件203向后滑动至所述退位槽处时，对所述活动套件203进行限位。
结合图22，当所述插接头206的前端插入所述光口适配器300时，所述光口适配器300内侧的弹性卡爪301恰好与所述插接头206外侧的卡槽2061耦合连接，此时所述弹簧2062处于自然状态，所述活动套件203前端的侧壁挤压在所述弹性卡爪301外侧，可防止所述弹性卡爪301外张与所述卡槽2061脱离，实现所述光纤连接器200与所述光口适配器300之间的紧固。此时将所述中间连接套205从初始位置开始绕所述尾套204旋转预设角度，可有效阻挡所述活动套件203向后滑动，使得所述活动套件203前端始终围在所述插接头206的弹性卡爪301外侧，从而有效防止所述弹性卡爪301外张与所述卡槽2061脱离。
结合图23，当需要将所述光纤连接器200从所述光口适配器300中拔出时，需先将所述中间连接套205旋转恢复至初始位置，然后将所述活动套件203向后滑动，所述弹簧2062在所述凸块2031的作用下被压缩，所述活动套件203滑动至所述中间连接套205的退位槽处，使得所述活动套件203前端的侧壁逐渐脱离所述弹性卡爪301，此时所述光纤连接器200的插接头206可从所述光口适配器300中拔出。
具体地，所述中间连接套205与所述活动套件203的配合关系可参考图24，在所述中间连接套205上，所述退位槽处的纵向尺寸C略小于所述 活动套件203内部的纵向尺寸D，以便所述活动套件203向后滑动时可滑动至所述退位槽处；所述退位槽处的纵向尺寸E则大于所述活动套件203内部的纵向尺寸D，使得所述中间连接套205在旋转预设角度后，可阻挡所述活动套件203向后滑动。其中，所述预设角度的取值范围为(0°，180°)，优选为90°；在图25中，左图中所述中间连接套205处于初始位置，所述中间连接套205旋转90°后如右图所示，此时所述中间连接套205可阻挡所述活动套件203向后滑动。
本申请实施例提供的上述有源光缆组件中，当光纤连接器插入光口适配器之后，可利用活动套件实现插接头与光口适配器之间的紧固，然后将中间连接套旋转来阻挡活动套件向后滑动，则活动套件可始终发挥其紧固作用，防止插接头与光口适配器的脱离。通过上述结构，光纤连接器与光收发器之间可实现可插拔连接，进而实现光收发器组装时不连接光缆的功能，可解决光收发器组装不便带来的光缆报废的问题。
实施例7
在上述实施例6的基础上，本申请实施例进一步提供了一种有源光缆组件的组装方法，用于组装实施例6中所述的有源光缆组件。如图25所示，组装方法主要包括以下步骤：
步骤21，将所述光纤连接器200前端的所述插接头206插入所述光口适配器300中，并利用所述活动套件203实现所述插接头206与所述光口适配器300间的紧固。
具体方法与实施例5中所述步骤11的操作过程相同，在此不做赘述。
步骤22，将所述光纤连接器200上的所述中间连接套205绕所述尾套204旋转预设角度，阻挡所述活动套件203向后滑动。
参考图22-图24，当所述插接头206插入所述光口适配器300中实现耦合后，将所述中间连接套205从初始位置开始绕所述尾套204旋转预设角 度，例如旋转90°，变化过程如图24所示。
组装完成后，当有向后的外力施加在所述光纤连接器200的活动套件203上时，因所述中间连接套205可有效阻挡所述活动套件203向后滑动，使得所述活动套件203前端始终围在所述插接头206的弹性卡爪301外侧，从而有效防止所述弹性卡爪301外张与所述卡槽2061脱离。
进一步地，在上述实施例的基础上，如果所述有源光缆组件需要返修拆解，则具体拆卸步骤如下：
首先，将所述光纤连接器200上的所述中间连接套205绕所述尾套204回转预设角度，回到初始位置。例如，当旋转角度为90°时，需要将所述中间连接套205从图24的右图位置旋转回左图位置。
然后，将所述活动套件203向后滑动至所述退位槽处，将所述光纤连接器200从所述光口适配器300中拔出，以便对所述光收发器400开壳返修。具体操作如下：向所述活动套件203施加与所述光收发器400方向相反的力，使所述活动套件203滑动至所述中间连接套205的退位槽处，所述活动套件203前端的侧壁逐渐脱离所述弹性卡爪301，此时向后拉动所述光纤连接器200可使所述弹性卡爪301外张与所述光纤连接器200，进而将所述光纤连接器200从所述光口适配器300中拔出。
本申请实施例提供的上述方法中，光纤连接器可方便地插入和拔出安装在光收发器上的光口适配器，即光纤连接器与光收发器之间可实现可插拔连接，使得光收发器的组装和拆解均无需携带光缆，操作方便高效，可解决光收发器组装不便带来的光缆报废的问题。
本领域的技术人员容易理解，以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
