具体实施方式
现在参见图1-5,显示的是扇出线缆组件10。多光纤线缆12在扇出器16处被扇出成分离的输出线缆14。多光纤线缆12在远端32处用多光纤连接器18(比如MTP连接器)端接。在画出的实施方式中,多光纤连接器18包括应力消除保护罩(protective strain relief boot)20。多光纤线缆12可以根据需要具有任何长度。在一些实施方式中,多光纤线缆12可长达几百英尺。扇出线缆组件10可被用于各种用到通信器材的实施方式和环境中。扇出器16可以让多光纤线缆12被分接或扇出成单独输出线缆14,所述单独输出线缆在远端34处用连接器22(比如画出的实施方式中的SC连接器)端接。为了表达清楚,仅示出了一个输出连接器22。在实际使用中,每个输出线缆14都会用连接器22端接。典型地,连接器22包括应力消除保护罩24。
在图4和5中可以看到,多个单独的光纤30被设置于多光纤线缆12内。单独的光纤30在扇出器16处被分接成单独的输出线缆14。输出线缆14也可被称作是分叉光纤。通常,单独的光纤30是裸光纤,比如250微米光纤,它们脆弱易损。当光纤从扇出器16延伸到器材中的光纤终端时,输出光纤14用它们的扇出线缆组件保护套以一对一的方式保护了单独的光纤30,即一线缆14对应一光纤。例如,扇出线缆组件10可与暗线箱一起使用,输入线缆12从所述暗线箱延伸到远程的多光纤连接装置上,扇出器16、输出线缆14和连接器22被装入暗线箱内并与暗线箱中的光纤适配器相连。
参见图1-8,扇出器16包括输入端40,和输出端50。应力消除保护罩44可定位在输入端40处用于线缆12。扇出器16包括扇出器组件主体42。主体42提供了装配到多光纤线缆12和输出线缆14的结构。优选地,主体42还限定了接收环氧树脂的壳体,环氧树脂是用于包围和固定在线缆12,14之间延伸的光纤30。在画出的实施方式中,主体42限定了在纵向方向上从输入端40延伸到输出端50的圆柱形。
多光纤线缆12被作为输入线缆组件60提供,如图9中所示。输入线缆组件60包括插入部62和压接部(crimp)64,它们连接到线缆护套68的近端66和线缆强度部件72的近端70上,比如芳纶(Kevlar)纱。压接部64将线缆护套68的近端66和线缆强度部件72的近端70保持到插入部62上。插入部62包括如图14和15中所示与主体42啮合的凹口74。
输出线缆14以输出分叉线缆组件80的形式提供,其为从输入线缆组件60延伸的光纤30提供了上护套(upjacket)82。如图10和11中所示,每个输出分叉线缆组件80包括外管84和内管86。提供了居中的强度部件88,比如芳纶(Kevlar)纱。插入部90用压接部92装配到外管84的近端81和强度部件88的近端83。内管86还可被加接于插入部90上,例如使用粘合剂(诸如环氧树脂)。
如图12中所示,每个输出分叉线缆组件80都被装配到主体42的内壳体100上。每个上护套82从内壳体100内侧被插入到内壳体100的开口102中。插入部90和压接部92在开口102中起到挡块的作用防止每个输出分叉组件80从内壳体100上掉落。一旦每个输出分叉组件80都就位了,输入线缆组件60通过将伸出的光纤30插入经过内管86的方式匹配起来,每个管86一根光纤30。
现在参见图13和14,带着输入线缆组件60和输出分叉线缆组件80的内壳体100被装配到主体42的下壳体部分120上。如图1-3和5-8所示,上壳体部分130装配到下壳体部分120以包封内壳体100。在上壳体部分10被装配以前,环氧树脂就被添加到凹穴111内的扇出器16内部。
图16和17中示出的固定装置150是用于在环氧树脂固定光纤工艺中保持住元件。每个固定装置150包括基部152,限定了多条通道154,每条通道用于接收扇出线缆组件10。钳夹棒156保持住钳夹块158,从而在环氧树脂工艺中将每个输入线缆组件60保持就位。如所示,凹口74在进口139处啮合肩部138从而相对于主体42定位插入部62。一旦被固定住,环氧树脂或其他材料可被浇注到凹穴111中以包围光纤30。
环氧树脂固化之后,上壳体部分130被装配到下壳体部分120和内壳体100上形成了主体42。带着内部光纤30的线缆14用连接器22端接从而完成了扇出线缆组件10。
现在参见图18-23,显示的是内壳体100的额外细节。内壳体100包括主体104,其具有第一端106和相反端108,并在纵向方向上延伸。用于输出线缆14的开口102被定位于端部106。两个侧延长部110从端部106延伸。侧延长部110与下壳体部分120配合形成了环氧树脂容器或凹穴111。在侧延长部110的外部109上有多个肋112,它们与外壳体部分120,130上的匹配构造配合将侧延长部110保持就位。定位凹口或键118被设在第一端106上。选定的光纤30可被按照需要放置在选定的开口102中。通过这种方式,开口102可被特定的光纤填充从而保持了组件10之间的连贯性。
现在参见图24-30,显示的是下壳体部分120的额外细节。上壳体部分130被构造成与下壳体部分120相同。下壳体部分120包括主体122,其具有第一端124和相反端126,在纵向方向上延伸。外部表面128限定为半圆柱形。在内部132上设置有用于与内壳体100的肋112匹配的多个侧凹槽134,和用于与侧延长部110的端部114匹配的端部凹槽136。内部132还限定了肩部138,所述肩部用于与输入线缆组件60插入部62的凹口74联接。下壳体部分120包括匹配揿合部140,142和对应的凹口144,146,用于将下壳体部分120揿合到上壳体部分130上。
主体42包括多个侧凹口160,用于接收堆叠起多个主体42的啮合结构。还提供了孔162用于装配到通信器材中。
包括了圆柱形主体42的扇出线缆组件10具有紧凑的设计。圆柱形主体42的一个优点是主体42在建立系统的过程中可被插入穿过通信器材中对应的小开口,比如暗线箱中各个区域间的圆形开口。
上述的具体说明、实例和数据提供了本发明制造和使用的完整介绍。由于本发明的许多实施方式可以在不脱离本发明的精神和范围的情况下做出,因此本发明的权利归属于此后所附的权利要求。
