背景技术
FTTH(光纤到户)系统中用户终端的配线分线设备大都采用光缆分线箱，但是分纤箱往往是用作终端分配光纤功用，安装位置固定。而分光分纤盒可满足一级分光或二级分光等不同的场景需求，体积小巧，适用多种使用场景如室内、楼道等。
分光分纤盒可用于光纤线路上的掏纤分光，在不砍断光缆的情况下完成分歧和管理，从一根光缆中取出需要的几根光纤，实现光纤的熔接、分配以及调度等功能，避免把光缆全部剪断重新熔接。

具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1至图5所示，本多用分光分纤盒包括：
盒体10，在盒体10上贯穿开设有供光缆80穿过的通道11；
熔接盘，固设在盒体10内且上述通道11位于熔接盘一侧；
插片盒，至少设置为一个，插片盒安装在熔接盘上，光缆80中的光纤在熔接盘内熔接后通过插片盒进行分光。
光纤在生活中的应用越来越广泛，使用时往往采用分光分纤盒对光纤进行掏接，在不破坏光缆80的情况下实现光纤的熔接、分配以及调度等功能。
本发明设计了一种多用分光分纤盒，盒体10底部扁平设计，可直接对铺设好的光缆80纵向开剥并进行掏接工作，不会影响光缆80的正常工作。光纤从光缆80剥离之后进入熔接盘内完成熔接工作，然后通过插片盒进行分光，操作简便，分光效果好。其中，通道11位于熔接盘一侧便于光纤被剥离光缆80之后直接进入熔接盘内。
如图1和图5所示，优选地，在盒体10上可拆卸安装有盒盖20，在盒体10两端分别开设有与通道11对应设置的第一缺口，在盒盖20两端分别开设有与第一缺口对应设置的第二缺口，同一端的第一缺口、第二缺口合围形成上述通道11的入口或出口，在通道11内设有多个支撑块12，每个支撑块12上均固设有均匀分布的多个凸起121。
同一端的第一缺口、第二缺口在盒盖20安装在盒体10上时，合围形成上述通道11的入口或出口，这样的设计便于开设通道11的入口或出口，制造简便。
实际工作时，其实是先将盒体10与光缆80连接在一起，所有工作完成之后，再将盒盖20安装在盒体10上，因此第一缺口和第二缺口的设计还便于将光缆80卡入通道11内，即可直接对铺设好的光缆80进行掏接工作，方便掏接工作的进行，不需要剪断光缆80，不会对光缆80造成其他影响。
支撑块12的设计是给位于盒体10内的光缆80提供一个支撑作用，本发明中，鉴于盒体10的尺寸以及结构的设置，优选支撑块12的数量为两个，且两个支撑块12分别靠近通道11的入口、出口设置，光缆80的开剥处位于两支撑块12之间，这样设置可以避免不必要的影响。凸起121的设置可以对光缆80有一定的防滑稳固作用，避免因外界影响造成光缆80松动从而导致光纤损坏的现象发生。
如图4和图5所示，优选地，熔接盘包括盘体31，在盘体31内开设有绕线槽35，在绕线槽35内设有卡固组件，卡固组件卡固有至少一个热熔管50。
进行掏接时，光纤一般有一定长度，此时可以盘绕在绕线槽35内。光纤的熔接具体是在热熔管50内进行的，而熔接一路光纤需要一个热熔管50，因此设置了卡固组件，可卡固多个热熔管50，可以满足同时熔接多路光纤的需求。
进一步优选地，卡固组件包括两列对称设置且均匀分布的卡板37，两列卡板37中相对的两个卡板37为一组，相邻的两组卡板37之间能卡固一个热熔管50。
相对的两个卡板37设置在同一直线上，两个卡板37相对的一端均朝向一侧微微弯曲，且采用软质材料制成，有一定的弹性。因此热熔管50卡固在相邻的两组卡板37(即四个卡板37)之间 稳定牢固，卡固效果良好。
本发明中鉴于盘体31的结构以及尺寸的设置，卡板37的数量优选为四个，能够卡固一个热熔管50。当然只要盘体31的结构、尺寸允许，可以设置更多的卡板37，卡固多个热熔管50，熔接多路光纤。
值得一提的是，卡固组件也可以直接设置成等间距分布的一列长条形板，相邻的两个长条形板之间卡固一个热熔管50，本发明中优选前一种方案。
优选地，在盘体31内还对称设置有两绕线柱33，环绕两绕线柱33设有与盘体31固连的环形挡板34，环形挡板34与两绕线柱33合围形成上述的绕线槽35且环形挡板34与盘体31的周侧壁合围形成绕线道36，绕线道36环绕绕线槽35设置。
具体地，掏接时光纤盘绕在两绕线柱33上，绕线道36的设置是方便光纤进入绕线槽35，具有导向作用，且绕线道36弯曲部位还设置了一定的弯曲曲率，可以避免光纤因弯曲过度而导致光纤损耗。
卡固组件可以选择适宜的安装位置，只要光纤不会过度弯曲即可，本发明中卡固组件靠近环形挡板34设置，卡固组件与环形挡板34之间亦可卡固一个热熔管50。
进一步优选地，在盘体31面朝光缆80的侧壁上开设有进纤口311，在环形挡板34远离光缆80的侧壁上开设有出纤口341，光纤依次通过进纤口311、绕线道36、出纤口341进入绕线槽35并与热熔管50相连。
进纤口311朝着光缆80的开剥处设置，光纤从光缆80中剥离出来之后，由进纤口311进入绕线道36，然后由出纤口341进入绕线槽35，最后进入热熔管50，多余长度的光纤可以盘绕在两绕线柱33上。其中，卡固组件与出纤口341相对设置。
优选地，在盘体31一端卡固有连接座60，在连接座60上安 装有至少一个尾纤90，尾纤90的一端通过连接头91与连接座60相连，另一端由出纤口341进入绕线槽35并与热熔管50相连，热熔管50用于熔接光纤和尾纤90。
尾纤90由出纤口341进入绕线槽35，进入热熔管50与光纤熔接，多余长度的尾纤90也可盘绕在两绕线柱33上。尾纤90上的连接头91安装在连接座60上，光纤通过连接头91可以与插片盒相连，从而实现光纤的分光功能。
连接座60上开设有安装连接头91的多个槽位，即可以安装多个尾纤90，也就是说可以熔接多路光纤，光纤、尾纤90、连接头91以及热熔管50一一对应。本发明中，槽位的数量优选为两个，至多可以熔接两路光纤，尾纤90、连接头91以及热熔管50的数量可以根据所需熔接光纤的数量来定。若是盒体10以及盘体31的结构、尺寸允许，可以设置更多的槽位，安装多个尾纤90，熔接多路光纤。
图5所示的光纤与尾纤90的盘绕只是一个范例，具体的盘绕可视实际使用情况而定。
进一步优选地，每个绕线柱33上均固设有环绕对应绕线柱33分布的多个第一凸耳332，在环形挡板34上固设有多个第二凸耳342，在盘体31的周侧壁上固设有多个第三凸耳312，各凸耳均呈水平设置。
各第一凸耳332由绕线柱33向外延伸，第二凸耳342中一部分朝着绕线槽35延伸，一部分朝着绕线道36延伸，而各第三凸耳312则朝着绕线道36延伸，这样的结构设计能够在绕线槽35以及绕线道36的上方形成一个屏障，避免光纤、尾纤90从绕线槽35或绕线道36内散出，避免光纤与其他工作部件缠绕在一起，影响正常工作。
如图2、图3和图6所示，优选地，插片盒包括本体41以及扣合在本体41上的盖板42，在本体41内固设有定位板44以及 分列在定位板44一侧且对称设置的两绕线块43，定位板44与本体41内侧壁合围形成条状区域，在条状区域内限位有用于对光纤分光的光分路器70，在本体41靠近连接座60的一端开设有卡槽413，在卡槽413内卡固有输入适配器头71，在本体41远离连接座60的一端开设有多个安装槽414，每个安装槽414内均能卡固至少一个输出适配器头72。
插片盒的工作原理是将一路或两路光纤分成多路光纤，由光分路器70来实现光纤的分光。光分路器70一端接一路或两路光纤，另一端输出多路光纤。
实施例一中，插片盒优选一分八的分光模式，即输入适配器头71的数量为一个，输出适配器头72的数量为八个，对应地，卡槽413的数量为一个，而安装槽414的数量为四个，每个安装槽414内均叠合安装有两个输出适配器头72。输入适配器头71与连接头91相连，连接座60的设置也方便了两者的连接。
这里的光分路器70为迷你型光分路器，可卡固在条状区域内，保持稳定性。光分路器70与各适配器头均通过光纤相连，多余长度的光纤可盘绕在两绕线块43上。
现有用于光纤分光的插片盒中，若是采用一分八的分光模式，则输出适配器头72的数量为九个，若是采用一分四的分光模式，则输出适配器头72的数量为五个。本实施例中一分八的分光模式采用八个输出适配器头72，可以在一定程度上减少光纤的衰减损耗，有利于光纤的使用。
进一步优选地，每个绕线块43上均固设有多个第四凸耳432，在本体41内还固连有多个第五凸耳412，各凸耳均呈水平设置。
各第四凸耳432、各第五凸耳412与上述的第一凸耳332、第二凸耳342以及第三凸耳312功能一致，形成一个屏障，避免光纤从本体41内散出，且避免光纤与其他工作部件缠绕在一起，影响正常工作。
如图4和图7所示，优选地，在盘体31上扣合设置有盘盖32，在盘盖32上固设有多个第一卡扣321，在本体41底部固设有与第一卡扣321一一对应的第二卡扣411。
插片盒通过各第一卡扣321与各第二卡扣411的配合作用卡固在熔接盘上的，便于拆装更换。此处，各卡扣的数量均优选为四个。
盘盖32的设置便于第一卡扣321的设置，方便插片盒卡固在熔接盘上，此外，上述盘盖32、盖板42的设置使得盘体31、本体41内的零部件不受外界的影响。
如图2至图5所示，进一步地，每个绕线柱33上均固设有第一卡块331，在盘盖32上开设有与两第一卡块331一一对应的两第一卡孔322，每个绕线块43上均固设有第二卡块431，在盖板42上开设有与两第二卡块431一一对应的两第二卡孔422。
盘盖32通过第一卡块331与第一卡孔322的配合工作扣合在盘体31上，同理，盖板42通过第二卡块431与第二卡孔422的配合工作扣合在本体41上，连接牢固且拆装方便，便于操作人员检查维修。
如图8和图9所示是本发明实施例二的结构示意图，与实施例一的不同之处在于，插片盒数量为多个，各插片盒相互叠合安装在熔接盘上，位于最下方的插片盒与熔接盘卡固连接，相邻的两个插片盒通过卡扣结构相连，在盖板42上固设有与第二卡扣411一一对应的多个第三卡扣421。
实施例二中的插片盒的结构与实施例一中的插片盒的结构并无二致，但是插片盒上的输出适配器头72的数量发生了变化。
本实施例中优选插片盒的数量为两个，下方的插片盒通过各第一卡扣321与各第二卡扣411的配合作用卡固在熔接盘上的，便于拆装更换。而盖板42上的各第三卡扣421可以与上方的插片盒上的各第二卡扣411配合作用，将两个插片盒叠合卡固在一起， 即相邻的两个插片盒通过卡扣结构相连。此处，各卡扣的数量均优选为四个。
本实施例中插片盒为两个，每个插片盒均优选一分四的分光模式，即输入适配器头71的数量为一个，输出适配器头72的数量为四个，对应地，卡槽413的数量为一个，安装槽414的数量为四个，每个安装槽414内均安装有一个输出适配器头72。输入适配器头71与连接头91相连，连接座60的设置也方便了两者的连接。
本实施例中一分四的分光模式采用四个输出适配器头72，同样可以在一定程度上减少光纤的衰减损耗，有利于光纤的使用。
优选地，在盒体10上设置有一列均匀分布的卡接单元，每个卡接单元均包括相对设置的两卡接块13且两卡接块13合围形成卡接槽14。
进一步优选地，在盒体10上开设有一列第一弧形缺口，在盒盖20上开设有与该列第一弧形缺口一一对应的一列第二弧形缺口，当盒盖20安装在盒体10上时，每个第一弧形缺口均与对应的第二弧形缺口合围形成通孔15，各通孔15与各卡接槽14一一对应。
本发明中，卡接单元的数量优选为八个，卡接槽14的数量也为八个，每个卡接槽14均对应一个输出适配器头72。其中，每个输出适配器头72均对应一个辅助适配器头，在每个辅助适配器头上均连接有光纤，光纤均卡接在对应的卡接槽14内，此外，各通孔15与各卡接槽14一一对应，因此光纤在穿过对应的卡接槽14后经过对应的通孔15伸出盒体10外，排列整齐、外形美观。
此处的第一弧形缺口、第二弧形缺口的设置与上述的第一缺口、第二缺口类似，便于开设通孔15且制造方便。
实施例一中，采用一分八的分光模式中，从光缆80中开剥出一路光纤，与一个尾纤90进行熔接，然后通过连接头91与插片 盒中的输入适配器头71相连，插片盒将一路光纤分成八路光纤，八路光纤分别通过对应的通孔15伸出盒体10。
实施例一中，如若需要对两路光纤进行分光的话，可在卡槽413内再叠合设置一个输入适配器头71，但相应地，需要先在熔接盘内熔接两路光纤。
实施例二中，每个插片盒均采用一分四的分光模式，从光缆80中开剥出两路光纤，分别与两个尾纤90进行熔接，然后通过两个连接头91分别与两个插片盒中的输入适配器头71相连，每个插片盒均将一路光纤经光分路器70分成四路光纤，最终八路光纤分别通过对应的通孔15伸出盒体10。
除此之外，插片盒当然还可以进行一分二的分光模式，即将一路光纤分成二路光纤，可以根据实际使用需求来选择，鉴于分光后的光纤与卡接槽14、通孔15一一对应，本发明中，分光后的光纤数量只需不超过卡接槽14或通孔15的数量即可。
值得一提的是，实施例一中也可进行一分四等其他分光模式，只要不超过熔接盘以及插片盒的容量即可。
如图2至图5所示，优选地，在盒体10上还固设有环绕熔接盘设置的多个定位块16。
定位块16的设置是保证熔接盘稳固在盒体10内，不易发生松动。定位块16的数量可视实际使用情况而定。
如图1和图4所示，优选地，在盒盖20两侧分别开设有连接孔21，在盒体10上开设有与两连接孔21对应设置的两连接槽17，每个连接槽17一侧均开设有安装孔18。
盒盖20与盒体10通过螺栓相连，连接牢固且拆装方便，连接孔21与连接槽17的设置便于螺栓的安装。安装孔18内也可以安装螺钉，方便将整个多用分光分纤盒安装在墙壁、楼道等地方。
本多用分光分纤盒在初始状态下，将盒体10与光缆80相连，从光缆80中开剥出光纤，光纤在熔接盘内与尾纤90通过热熔管 50熔接在一起，然后光纤通过插片盒实现分光功能，整个多用分光分纤盒操作简便、可采用多种分光模式，实用性好且光纤分光效果好。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
