具体实施方式
在不冲突的情况下，实施例中的特征可以相互任意组合。实施例1
请参考图1至图9，本实施例提供了一种光纤连接结构，包括第一连接器1和适配器2，第一连接器1包括第一本体11、第二本体12和滑动件13，第一本体11和第二本体12配合插接，滑动件13可滑动的套接在第二本体12的外部其中，外部是指第二本体的外表面，第一本体11的侧部从内向外延伸设置有卡爪111，其中，第一本体11的内部是指第一本体11的里面，第一本体11的外部是指第一本体11的外面，卡爪111的外侧设置有卡接凸起1111，其中卡爪111的外侧是指卡爪111远离第一本体11的内部，滑动件13设置有与卡爪111相配合的解锁面131，适配器2上设置有与卡接凸起1111配合的凹陷部21。第一本体11和第二本体12插接，卡爪111卡接解锁面131，第二本体12与适配器2插接，卡接凸起1111卡接凹陷部21；解除卡接时，滑动滑动件13，解锁面131推动卡爪111向内移动，带动卡接凸起1111向内脱离凹陷部21。卡爪111从第一本体11的侧部向外延伸，通过卡接凸起1111与适配器2上的凹陷部21卡接，将适配器2和第一连接器1固定，卡爪111不再单独设置于第一本体11的外侧，几乎不占用第一本体11外部的空间，适配器2也只需要与第一本体11的结构相适应，适配器2与第一连接器1的占用空间均减少，提高了适配器2与第一 连接器1的排布密度，且通过滑动件13实现卡爪111的收缩，操作简便，便于插拔。凹陷部21可以是凹槽，可以是通孔，对此不作限定，只要与卡接凸起1111配合卡接固定即可。第一本体11相对设置至少两个卡爪111，每个卡爪111均有解锁面131配合，卡爪111的外侧均设置有卡接凸起1111，与适配器2配合卡接。相对设置的卡爪111将第一本体11的相对的两侧与适配器2配合，结构稳定，卡接牢固，受力均匀。
如图4所示，卡爪111的外侧设置有外宽内窄的推动面1112，外宽内窄是指从推动面1112从卡爪111的内部向外侧(如第二本体12)的方向，从卡爪111的中部向外侧倾斜。如图5和图6所示，滑动件13的内侧向内凸出设置有解锁凸起，解锁凸起的内侧面作为解锁面131，解锁面131与推动面1112相配合，如图4和图7所示，滑动件13向远离第一本体11的方向滑动时，解锁面131推动推动面1112，带动卡爪111向内移动。通过向内凸出的解锁凸起，可以更好的与卡爪111相配合。第二本体12的后端还设置有限位凸台，限制滑动件13向外滑动的极限位置。
滑动件13还固定有用于拉动滑动件13移动的拉手14，不需要直接去推动滑动件13，直接拉动拉手14即可，且推动件13处的操作空间比较小，拉手14的操作空间大，便于操作。拉手14的一端分成两个拉手部141，两个拉手部141分别与滑动件13相对的两端卡接，卡爪111设置在两个拉手部141的连线的侧部。两个拉手部141分别从相对的两侧拉动滑动件13，滑动件13受力均匀，且卡爪111与拉手部141分布在不同的侧部，可以避免滑动件13在同一侧部的受力过大。限位凸台上设置有用于拉手部141通过的限位孔，便于拉手部141与滑动件13的卡接。
如图8所示，适配器2还连接有第二连接器3，第二连接器3与第二本体 12相对设置，第二连接器3的外侧设置有定位凹槽31，适配器2设置有向内凸出的定位凸起22，第二连接器3与适配器2通过定位凸起22与定位凹槽31相卡接。第二连接器3设置在面板内，作为内部连接器，通过适配器2与第一连接器1连通。
适配器2内还设置有遮光板，遮光板与适配器2的侧壁铰接，且通过回复部件保持与适配器2的插入端口平行的关闭状态，当第一本体11从插入端口插入适配器2，推开遮光板，当第一本体11拔出，回复部件推动遮光板关闭。回复部件可以是扭簧等，推动遮光板保持在关闭状态即可。
实施例2
与实施例1不同的是，卡爪111的外侧设置有外窄内宽的推动面，解锁面131与推动面相配合，滑动件13向第一本体11的方向滑动时，解锁面131推动推动面，带动卡爪111向内移动。外窄内宽是指从推动面从卡爪111的内部向外侧(如第二本体12)的方向，从卡爪111的外侧向中部倾斜。此种结构的解除第一连接器1和适配器2之间的卡接的方式，与实施例1相反。
实施例3
参考图10至图13，本实施例提供了一种光纤连接模组，包括上述的的光纤连接结构，还包括模组盒4，模组盒4的一端固定有卡接框41，参考图2，适配器2的相对的两侧设置有向外弹出的外部卡接弹片23，外部卡接弹片23的延伸方向间隔设置有阻挡部24，至少两个适配器2密集排布于卡接框41，每个适配器2的外部卡接弹片23和阻挡部24分别卡接在卡接框41的两侧，以固定适配器2于卡接框41。通过上述的光纤连接结构，减少了第一连接器1和适配器2 占用的空间，可以提高适配器2和第一连接器1的排布密度，且适配器2不需要通过法兰固定在模组盒4上，直接通过外部卡接弹片23卡接在卡接框41上，与模组盒4固定，减少了法兰占用的空间，更加提高了适配器2的排布密度。
参考图12和图13，光纤连接模组还包括模组面板5，模组面板5的侧壁围成用于容置模组盒4的空腔，模组盒4的侧部设置有向外弹出的模组盒凸起42，模组面板5的侧壁设置有与模组盒凸起42相配合的模组定位孔51，便于模组盒4和模组面板5之间的固定。模组面板5的大小与传统的面板一致，通过上述的光纤连接结构和模组盒4，在大小相同的模组面板5中可以装载多一倍的适配器2，极大地提高了适配器2的排布密度，既能满足高传输速度的光纤网络的需求，又不需要更改相关技术中的机柜的结构，节约成本，使用方便，通用性强。图12是1U的光纤连接模组的装配图。其中，是1U大小的模组面板5与模组盒4组合的装配图，其中，U是表示配线架或模组面板5的外部尺寸的单位，是unit的缩略语，相关技术中，1U＝44.45mm，2U是88.9mm。图13是2U的光纤连接模组的装配图。通过使用上述的光纤连接结构，1U和2U大小的模组面板5中可以组装更多的光纤连接结构，提高了组装密度。
以上内容仅为本申请的可选实施例，本说明书内容不应理解为对本申请的限制。
工业实用性
本申请实施例提供一种光纤连接结构及光纤连接模组，卡爪从第一本体的侧部向外延伸，通过卡接凸起与适配器上的凹陷部卡接，将适配器和第一连接器固定，卡爪不再单独设置于第一本体的外侧，几乎不占用第一本体外部的空间，适配器也只需要与第一本体的结构相适应，适配器与第一连接器的占用空 间均减少，可以提高适配器和第一连接器的排布密度，且通过滑动件实现卡爪的收缩，操作简便，便于插拔。
