光纤熔配模块是光纤配线架和光缆交接箱中的重要部件，主要用于实现外部光缆与尾纤的熔接，以及通过适配器将熔接后的尾纤与跳纤进行连接的功能。实际使用时，光纤熔配模块需要插装在光纤熔配框内，然后再将该光纤熔配框安装在光纤配线架上或者光缆交接箱内，即可实现光端设备与光纤链路的连接。
相关技术中，一个1U(即高度为44.45毫米，宽度为482.6毫米)的光纤熔配框中一般可以插装两个熔配模块，每个熔配模块可以安装12个卡接式方型(英文：Square connector；简称：SC)适配器或12个朗讯(英文：Lucent connector；简称：LC)双联适配器。使用时，可以通过熔配模块中的熔接盘将外部光缆与尾纤的一端进行熔接，该尾纤的另一端具有多个适配器接口，能够与该多个适配器的一端一一对应相连，该多个适配器的另一端用于连接跳纤，该跳纤可以与光端设备连接，由此即可实现光端设备与光纤链路的连接。
但是，相关技术中的光纤熔配模块只能实现将外部光缆与尾纤进行熔接，以及将熔接后的尾纤与跳纤进行连接的功能，该光纤熔配模块的功能较为单一。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
图1是本发明实施例提供的一种光纤熔配模块的结构示意图，如图1所示，该光纤熔配模块可以包括：壳体01，以及与该壳体连接的熔接盘02。
该壳体01的一端设置有多个第一适配器03，该壳体01的另一端设置有活动板011，如图2所示，该活动板011上设置有适配器安装孔012，该适配器安装孔012用于安装第二适配器，该活动板011与该壳体01可拆卸连接。
其中，参考图3，当该活动板011与该壳体01连接，且该适配器安装孔012上安装有第二适配器04时，该第二适配器04的一端用于连接外部光缆，另一端用于通过分支跳线与该多个第一适配器03相连；当将该活动板011拆卸时，如图4所示，该壳体01的另一端形成开口013，该外部光缆能够通过该开口013进入至该壳体内，并通过图1所示的熔接盘02与尾纤的一端熔接，该尾纤的另一端用于与该多个第一适配器03相连。
综上所述，本发明实施例提供的光纤熔配模块中设置有可拆卸的活动板，该活动板上设置有用于安装第二适配器的适配器安装孔，当该活动板与光纤熔配模块的壳体连接时，可以通过分支跳线对不同类型的适配器进行配线，当该活动板拆卸时，可以实现将外部光缆与尾纤进行熔接，以及通过第一适配器将熔接后的尾纤与跳纤进行连接的功能，该光纤熔配模块的功能较为丰富。
进一步的，在本发明实施例中，如图3所示，该壳体01可以包括底板01a以及设置在该底板四周的挡板01b；该壳体一端的挡板上设置有该多个第一适配器03；该壳体01另一端的挡板上设置有该活动板011。参考图5，该熔接盘02与该壳体01可拆卸连接。
一方面，在该活动板011从该壳体01上拆下，即该活动板011与该壳体01未连接时，如图6所示，该熔接盘02可以设置于该壳体10内。此时，外部光缆可以通过壳体另一端的开口013进入壳体内，该光纤熔配模块可以通过该熔接盘02对外部光缆和尾纤进行熔接。由于该尾纤的另一端能够与该多个第一适配器03相连，该多个第一适配器03的另一端能够通过跳纤与光端设备相连，由此即可实现外部光缆与光端设备的连接。此外，如图6所示，当采用熔接盘02对外部光缆和尾纤进行熔接时，该光纤熔配模块中还可以设置有熔接保护套管07，该熔接保护套管07可以套接在该熔接后的光纤上，以保护该外部光缆和尾纤的熔接部位。
需要说明的是，在本发明实施例中，该第一适配器可以包括SC适配器、LC双联适配器或者FC适配器中的任一种。
在实际应用中，作为一种可选的实现方式，如图6所示，该壳体01的一端设置的适配器03可以为12个SC适配器，此时该壳体01上的开口013可以引入一根12芯光缆的裸纤到熔接盘02，然后将一根12芯的SC尾纤(即尾纤一端的接口类型为SC型)的一端与该12个SC适配器对应相连(例如通过SC连接器031与该SC适配器相连)，将该尾纤在壳体内的绕线柱上盘绕后引入到熔接盘02内，与该12芯的裸纤熔接，由此可以实现12芯光缆与SC尾纤的熔接。
作为另一种可选的实现方式，如图7所示，该壳体01的一端设置的适配器03可以为12个LC双联适配器，此时该壳体01上的开口013可以引入两根12芯光缆的裸纤到熔接盘02，然后将一根24芯的LC尾纤的一端与该12个LC双联适配器对应相连(例如通过LC连接器031与该LC适配器相连)，将 该尾纤在壳体内的绕线柱上盘绕后引入到熔接盘02内，与该两根12芯的裸纤熔接，由此可以实现两根12芯光缆与LC尾纤的熔接。
另一方面，如图3所示，在该活动板011与该壳体01保持连接时，该熔接盘02从该光纤熔配模块中拆除，也即是，可以将该熔接盘02从该壳体01内拆下，此时可以在该光纤熔配模块中的活动板011上安装第二适配器04，并通过光纤跳线实现该第二适配器04与该多个第一适配器03的连接，由于该第二适配器04的一端能够连接外部光缆，该多个第一适配器03的另一端能够通过跳纤与光端设备相连，由此也能实现外部光缆与该光端设备的连接。
在本发明实施例中，该第二适配器可以为MPO适配器。并且如图2所示，该活动板011上可以设置有两个适配器安装孔012。
在实际应用中，作为一种可选的实现方式，如图3所示，该壳体01的一端可以设置有12个SC适配器03，该适配器安装孔中安装有一个MPO适配器04，该一个MPO适配器04可以通过一根分支跳线与该12个SC适配器对应相连，由此可以实现MPO-12SC配线的功能；作为另一种可选的实现方式，如图8所示，该壳体01的一端可以设置有12个LC双联适配器03，该适配器安装孔中安装有两个MPO适配器04，该两个MPO适配器可以通过两根分支跳线与该12个LC双联适配器对应相连，由此可以实现2MPO-24LC配线的功能。
需要说明的是，在实际应用中，该第二适配器还可以为其他类型的多通道型的适配器，该第一适配器除了可以为上述实施例中所述的SC适配器和LC适配器，还可以为其他类型的单通道型适配器，例如FC适配器等，本发明实施例对该第一适配器和第二适配器的类型不做具体限定。
在本发明一种优选的实施例中，参考图2，该活动板011可以为敲落孔，该敲落孔的大部分孔边缘已与该壳体01切断，而仅留了一些连接点。当需要将该活动板011拆卸时，只要用榔头或钳子之类的工具将该连接点部分敲断，就可以得到如图4、图6或图7所示的完整的开孔013。也即是，当该活动板011与壳体01拆卸后便无法再次安装，相对于可重复安装的结构，该敲落孔的 设计可以有效降低该光纤熔配模块的制造成本。
在实际使用该光纤熔配模块时，可以先确定外部光缆与该光端设备的连接方式，当需要对不同类型的适配器通过光纤跳线进行配线，以实现外部光缆与该光端设备的连接时，可以保留该活动板，并将熔配盘从壳体内拆下；当需要采用外部光缆与尾纤熔接的方式进行连接时，则可以直接将该活动板敲落。本发明实施例提供的光纤熔配模块可以通过不同方式实现外部光缆与该光端设备的连接，该光纤熔配模块的功能较为丰富，使用灵活性较高。
进一步的，如图5所示，该光纤熔配模块还包括：绕线柱05和盖板06；该绕线柱06设置在该底板01a上，用于盘储尾纤或者分支跳线；该熔接盘02设置于该绕线柱05的上方，且与该壳体01活动连接，能够向远离该底板01a的方向翻转。
示例的，如图5所示，该熔接盘02的两侧可以分别设置有柱状凸起结构，该壳体01内侧与该柱状凸起结构对应的位置处形成有凹槽，该熔接盘02两侧的柱状凸起结构能够插入至该凹槽内。由于该柱状凸起结构能够在该凹槽内转动，因此可以使得该熔接盘02向远离该底板01a的方向翻转。如图5所示，当该熔接盘02处于打开状态时，该熔接盘02底部的绕线柱05露出，以便操作人员能够将多余的尾纤或者分支跳线缠绕在该绕线柱05上。
进一步的，如图5所示，该盖板06设置于该壳体01开口所在面上，且与该壳体01一端的挡板活动连接，例如，可以与该设置有第一适配器03的挡板活动连接。该盖板06能够向远离该底板01a的方向翻转，以便操作人员可以对该壳体01内部的组件进行操作和维护。其中，该盖板06可以为透明盖板，以便于对该光纤熔配模块壳体内部的组件进行观察。
需要说明的是，本发明实施例提供的光纤熔配模块中的所有组件均可以为塑料材质，且该各个组件之间可以均采用卡装装配，无需使用螺钉，装配简单，且成本较低。
综上所述，本发明实施例提供的光纤熔配模块中设置有可拆卸的活动板， 该活动板上设置有用于安装第二适配器的适配器安装孔，当该活动板与光纤熔配模块的壳体连接时，可以通过分支跳线对不同类型的适配器进行配线，当该活动板拆卸时，可以实现将外部光缆与尾纤进行熔接，以及通过第一适配器将熔接后的尾纤与跳纤进行连接的功能，该光纤熔配模块的功能较为丰富。
图9是本发明实施例提供的一种光纤熔配框的结构示意图，如图9所示，该光纤熔配框可以包括：熔配框主体20以及插装在该熔配框主体20内的至少一个光纤熔配模块00，该光纤熔配模块00可以为图1至图8任一所示的光纤熔配模块。
如图9所示，每个光纤熔配模块00中设置有多个第一适配器03；该熔配框主体20上，靠近该第一适配器03的位置处设置有开口，该开口的一侧设置有过纤环30，跳纤能够穿过该过纤环30和该熔配框主体20上的开口，与该熔配模块00中的第一适配器03连接。由于该多个第一适配器03需要连接多根跳纤，该过纤环30能够对该多根跳纤进行收整，避免跳纤过于杂乱。
具体的，如图9所示，该熔配框主体20包括底板201以及设置在该底板四周的挡板；该熔配框主体20中的第一挡板202和第二挡板203的外侧分别设置有该过纤环30，其中，该第一挡板202和该第二挡板203相对设置，且均垂直于该第一适配器03的安装面。
进一步，如图10所示，该过纤环30上可以设置有活动卡扣301，通过该活动卡扣301能够将该过纤环30打开或者闭合，以便于对该多根跳纤进行整理。示例的，如图10所示，该活动卡扣301的一端与该过纤环30的主体转动连接，该活动卡扣301的另一端为翻折结构，该翻折结构能够卡接在该过纤环主体上的卡扣凹槽302内。当需要从该熔配框主体内取出光纤熔配模块或者需要拆除整理跳纤时，可以将该过纤环上的活动卡扣301打开，以便将整束跳纤取出或拆除。
可选的，如图9所示，该光纤熔配框还可以包括：托盘40；该托盘40设 置在该光纤熔配框的底板201上，且与该底板201活动连接，该光纤熔配模块00插装在该托盘上。实际插装时，该光纤熔配模块00不仅可以从该光纤熔配框的正面(即图9中靠近该第一适配器03的一面)插装到该托盘40上，还可以从该光纤熔配框的反面插装到该托盘40上，该光纤熔配模块的插装方式较为灵活。同时，由于该托盘40与该底板201活动连接，该托盘能够从该底板201中抽出，以便操作人员对该光纤熔配模块进行不同类型的操作，例如，插接跳纤或者检修维护等。
在本发明实施例中，该光纤熔配框可以为1U式的熔配框，即该熔配框主体的高度可以为44.45毫米，宽度可以为482.6毫米。需要说明的是，44.45毫米为1U式的熔配框的理论高度，在实际设计时，熔配框主体的高度一般会低于44.45毫米，以保证该光纤熔配框能够顺利插装至光纤配线架上。
如图9所示，该熔配框主体20内，沿该熔配框主体的宽度方向x可以依次插装有4个光纤熔配模块，相对于相关技术中1U式的光纤熔配框中只能插装两个熔配模块，本发明实施例提供光纤熔配模块00的尺寸较小，结构更为紧凑，从而使得该熔配框主体内可以插装4个光纤熔配模块。由于其中每个光纤熔配模块可以安装12个SC适配器或12个双联LC适配器，满配时端口数量能够达到48芯SC端口或者96芯LC端口，因此有效增加了该光纤熔配框的端口密度。
可选的，该光纤熔配框还可以包括：上盖；该上盖设置于该熔配框主体20开口所在面上，且与该熔配框主体20可拆卸连接。示例的，如图9所示，该上盖可以包括第一上盖501和第二上盖502。其中，该第一上盖501与该熔配框主体20盖合时位于该熔配模块00的上方，该第二上盖502与该第一上盖501配合可以将该熔配框主体20的开口完全盖合。其中，第二上盖502可以与该熔配框主体20固定连接，该第一上盖501可以与该熔配框主体20以及该第二上盖502可拆卸连接，以便通过拆卸该第一上盖501对该熔配框主体20内部的组件进行操作或维护。
需要说明的是，本发明实施例提供的熔配框主体还可以为多U数的熔配框，例如可以为2U或者3U的熔配框，本发明实施例对此不做限定。
综上所述，本发明提供了一种光纤熔配框，该光纤熔配框中插装的光纤熔配模块的数量较多，有效提高了光纤熔配框的端口密度。此外，该光纤熔配框中还设置有过纤环，该过纤环能够通过活动卡口打卡或者闭合，有效降低了对跳纤进行拆除和整理时的难度。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
