具体实施方式
描述了一种光纤分支组件,其通过将承载多根光纤的单根线缆过渡到分别承载多根光纤中的一根的多根单独的分叉(或分护套)管(或线缆)来辅助形成分支线缆。在图1中示出了示例性现有技术的分支线缆10。所示的分支线缆10包括多光纤线缆12,该多光纤线缆支撑多光纤连接器14并在线缆内承载多根光纤(未示出)。所示的分支线缆10还包括多个分叉管16,每个分叉管支撑一个光纤连接器18,并且每个分叉管承载穿过多光纤线缆12行进的多根光纤中的一根。优选地,等同数量的分叉管用于光纤的数量。在其他示例中,可以将多于一根的光纤组织成组并插入每个管16中。
图示的分支20(或分支:护罩、装置、套管)在多根光纤从多光纤线缆12内过渡到多个分叉管16时保护多根光纤。如图所示,多光纤线缆10在一侧插入分支20,并且多个分叉管16在另一侧插入分支中。
过渡组件(或装置或设备)可以起到改善光纤从单个较大的线缆(例如线缆12)到多个较小的分叉管(例如管16)的过渡的作用。这种过渡组件可以被支撑(或被容纳或保持)在护罩结构(例如图1中所示的分支20)内,以接收单根线缆和多个分叉管;使光纤在所述单根线缆和多个分叉管之间过渡。
示例性的较宽的多光纤线缆的直径可以在约3.6mm与4.0mm之间,并且更优选地为约3.8mm。这种较宽的多光纤线缆可以容纳多根光纤,例如,约在20到28根之间,更优选的是24根。另一个示例的较小的多光纤线缆的直径可以在约2.8mm和3.2mm之间,更优选的是约3.0mm。这种较小的多光纤线缆可以容纳约10到14根光纤,更优选地,可以容纳12根光纤。然而,多光纤线缆的总体尺寸和承载的光纤数可以变化。
提供了一种改进的过渡组件,以根据需要和情况允许可变和可互换的组件。改进的过渡组件包括过渡壳体,该过渡壳体容纳承载一根或多根光纤的多光纤线缆。过渡组件还包括分支保持器或端盖,以用于容纳多个分叉管。容纳在分支保持器中的分叉管的数量和尺寸可能会有所不同。多个光纤从多光纤线缆中分出,并穿过过渡壳体和分支保持器过渡到分叉管中。根据需要,过渡组件可以与相同的过渡壳体一起使用,但可以使用不同的分支保持器。例如,如果只需要三个分叉管,则分支保持器可以有三个分支导向部。或者,如果需要12或24个分叉管,则可以使分支保持器仅带有一个分支导向部,以容纳成捆的所有分叉管。因此,过渡组件允许将具有多根光纤的通用多光纤线缆与通用过渡壳体一起使用,但是允许用户根据所需的分叉管数量使用具有各种数量和尺寸的分支导向部的各种分支保持器中的一种。
在图2至图10中示出了示例性过渡组件100。所示的过渡组件100包括过渡壳体110(或壳体主体)和分支保持器114(或端盖),以用于将通过单根多光纤光缆104(KEVLAR)的多根光纤102过渡到多个分叉管106中。在所示的示例性过渡组件100中,十二根光纤102从一根多光纤线缆104过渡到三个分叉管106中,其中四根光纤过渡到每个分叉管中,但是可以使用任何合适数量的光纤和/或分叉管。优选地,但非必须地,多光纤线缆104大于分叉管106之一。
如图3、7、9和10中特别所示,所示的多光纤光缆104被插入并容纳在壳体110中的线缆入口112中。如图9和10中特别所示,所示的多光纤线缆104的远端插入并穿过线缆入口112,并延伸了一段较短的距离,例如在约1/16英寸(1.58毫米)和约1/4英寸(6.35mm)之间、优选约1/8英寸(3.17mm),以进入壳体110中的分叉室116(或分支室)。所示的线缆入口112和分叉室116在操作地且相邻地对准以形成光纤102从多光纤线缆104过渡出来的连续路径。
如图10中特别示出,所示的线缆入口112由壳体110内的空间限定,线缆102通过与分叉室116相对的开口端插入壳体中。所示的线缆入口112从第一端延伸至第二端。为了说明的目的,第一端位于离分叉室116最远的位置(远端),第二端最靠近分叉室(近端)。线缆入口112的第一端和第二端之间的距离用L1表示。示例性的长度L1可以在约0.40英寸(10.16mm)和0.60英寸(15.24mm)之间的范围内,优选地为约0.50英寸(12.7mm)。
所示的线缆入口112可限定从第一端到第二端的渐缩间隙。该渐缩间隙在插入过程中为线缆104在线缆入口112内的运动或游动提供了空间。X1表示第一端处的间隙,X2表示第二端处的间隙。示例性的间隙X1可以在约0.16英寸(4.06mm)至0.19英寸(4.83mm)之间的范围内,优选地为0.186英寸(4.72mm)。示例性的间隙X2可以在约0.13英寸(3.3mm)至0.159英寸(4.04mm)之间的范围内,优选地为0.156英寸(3.96mm)。所示的线缆入口112的间隙优选地具有圆形的几何形状,使得间隙的尺寸代表直径。
所示的线缆入口112优选地在第一端和第二端之间具有一致的锥度,例如在约4%至8%之间的范围内的斜度(根据所测量的方向为正的或负的),优选为约6%。
在使用中,如在图9和10中特别描绘的那样,线缆104的宽度或直径小于线缆入口112的第一端和第二端的间隙,因此在线缆104和线缆入口的间隙表面之间留有空隙。
如图3、7和10中特别所示,所示的壳体110还可以包括倒角漏斗127(表面),以将线缆104引导到线缆入口112的第一端。该倒角漏斗127还为线缆104位于线缆入口112和壳体110的外部的长度提供一定程度的灵活性。
如在图8和9中特别描绘的,所示的分叉室116由壳体110内的空间限定,光纤102通过该空间在多光纤光缆104的靠近线缆入口112的第二端的远端和壳体中的与线缆入口相对的开口端113之间延伸。分叉室116优选地具有足够的空间,以使得所示出的十二根光纤102能够裸露且未被覆盖地从线缆过渡,并具有额外的未使用的空袭空间。
如图2-7和9特别所示地组装的分支保持器114在开口端113处与壳体110接合。所示的分支保持器114接收延伸通过分支导向部120的分叉管106,其中分支导向部120延伸穿过分支保持器。所示的分支保持器114包括三个分支导向部,以容纳三个分叉管106,然而,根据分叉管的数量,可以使用替代数量的分支导向部,例如,一、二、三、四、五、六、七、八、九、十、十一、十二、十三、十四、十五、十六、十七、十八、十九、二十、二十一、二十二、二十三和二十四个。另外,根据光纤的数量、分叉管的数量以及用户的需求,可以有更多数量的分支导向部。分支导向部可以彼此等距地和/或以几何图案布置在分支保持器内。
所示的分支导向部120限定了由尺寸D1表示的间隙。示例性的尺寸D1可以在约0.100英寸(2.54mm)至0.200英寸(5.08mm)之间的范围内,优选地为约0.140英寸(3.56mm)。所示的分支导向部120可以具有圆形的几何形状,使得间隙尺寸D1代表直径。优选地,分叉管106与分支导向部120的间隙表面之间存在空隙。
如图4中特别所示,所示的分支导向部114的长度可以用尺寸X3表示,该长度可以在约0.20英寸(5.08mm)至0.30英寸(7.62mm)之间,优选为0.25英寸(6.35mm)。所示的分支导向部120的间隙D1(图6)优选地沿整个长度X3是一致的。然而,如图6中特别示出的,每个分支导向部120可以由离壳体110最远的一侧处的倒角漏斗125进入,以便为离开分支导向部的分叉管106提供一定范围的灵活性。
如图9中特别所示,当分支保持器114与壳体110的开口端113接合时,分叉管106延伸分支导向部120的长度X3,并且延伸一段短的距离(例如在约1/16英寸(1.58mm)和约1/4英寸(6.35mm)之间,优选为约1/8英寸(3.17mm))进入分叉室116中,使得分叉管的远端在壳体中在非常靠近分支保持器处终止。光纤102裸露且未被覆盖地通过分叉室116在多光纤线缆104和分叉管106之间延伸。
如图8-10中特别所示,随着光纤102离开多光纤线缆104和分叉管106的远端,一定量的芳族聚酰胺纱线117也从多光纤线缆和分叉管内露出。芳族聚酰胺纱线117被包括以对延伸通过多光纤线缆104和分叉管106的光纤102提供保护和支撑。
如图2-7和9中特别所示地组装,当支撑分叉管106的分支保持器114与壳体110的开口端113接合时,分叉室116基本上被容纳。如斑点特征部所示,一定量的环氧树脂108被填入或注入分叉室116中,并且少量环氧树脂可能自然地进入线缆入口112中的围绕线缆104的空隙以及分支导向部120中的围绕分叉管106的空隙。然后使环氧树脂108干燥和硬化,从而将光纤102和芳族聚酰胺纱线117固定在分叉室116内,并将分支保持器114固定成与壳体110硬化接合。任何量的硬化环氧树脂进入线缆入口112和/或分支导向部120中还可将线缆104和分叉管106分别在线缆入口和分支导向部内固定就位。一旦环氧树脂108的体积硬化,线缆104、壳体110、光纤102、芳族聚酰胺纱线117、分支保持器114和分叉管106就成为单个且坚固的个体。
一定体积的环氧树脂108通过延伸穿过壳体110以进入分叉室的填入窗122被填入或注入分叉室116中。所示的填入窗122可以具有长形的矩形形状,但是,允许将一定量的环氧树脂108引入分叉室116中的任何几何形状都是有效的。
一定量粘合剂109(以斑点特征部指示)通过穿过壳体110延伸以进入线缆入口112的填入端口118填入或注入。所示的填入端口118可以具有圆形形状,然而,允许一定量的粘合剂109被引入到线缆入口112中的任何几何形状都可以是有效的。粘合剂109与多光纤线缆104接触地硬化,以将多光纤线缆在线缆入口112内固定就位。优选地,在组装期间,在分支导向部114接合壳体110的开口端13之前、在将分叉管106插入分支导向部120中之前以及在将环氧树脂108注入分叉室116中之前,将多光纤线缆104通过粘合剂109固定在线缆入口112内。
为了制备过渡组件100,将多光纤线缆104的的护套足够长度切除,以露出其中的一定长度的光纤102和一定量的芳族聚酰胺纱线117。露出的光纤102、芳族聚酰胺纱线117和线缆104的远侧切割端穿过线缆入口112插入,直到线缆的远端稍稍从线缆入口延伸出而进入分叉室116中。在这种情况下,一段显著长度的未被覆盖的裸露的光纤102延伸穿过分叉室116的长度并且穿过壳体110的开口端113。然后将一定量的粘合剂109注入到填入端口118中,以将线缆104固定在线缆入口内112。
然后,基于待要在分支组件中使用的分叉管106的数量,将光纤102分为几组。优选地,这些组将各自具有相同数量的光纤102。如图所示,光纤102被分成三组,每组四根光纤。
然后将分支保持器114定位成使得每组光纤102穿过分支导向部120插入。分支保持器114然后在光纤102上滑动以与壳体110的开口端113接合对准,以基本上包含和限定分叉室116。
然后,将分叉管106装配在延伸穿过分支导向部120的光纤102上。如图所示,将三个分叉管106装配在三组光纤102上。优选地,一定量的芳族聚酰胺纱线117从分叉管102内露出。然后,将分叉管106进一步装配在光纤102上,直到将分叉管插入到分支保持器114的分支导向部120中,并且一定长度的光纤裸露且未被覆盖地延伸穿过分叉室116。在该位置处,分叉管106的远端和一定量的芳族聚酰胺纱线117被略微地插入至分支导向部120之外并进入分叉室116中。优选地,将适当量的张力施加到线缆104和分叉管106上,以确保光纤102在分叉室116内大体上是直的。
然后将一定量的环氧树脂108通过填入窗122注入到分叉室116中。优选地,注入的环氧树脂108的量完全充满分叉室116。合理地,一定量的环氧树脂108也将进入或渗入线缆入口112和分支导向部120中。然后将环氧树脂108留下并使其硬化或固化,从而形成单个且坚固的过渡组件100。
在图11至18中示出了另外的示例性过渡组件200。所示的过渡组件200包括如在上文的图2-10中所述的壳体110和线缆104。所示的过渡组件200包括与上述分叉管106相同的分叉管。所示的过渡组件200包括与如上所述的光纤102相同的光纤。所示的过渡组件200包括与上述的相同数量(十二根)的光纤102。所示的过渡组件200将每根光纤102单独地装配到分叉管106中,从而存在十二个分叉管。
如图11至图14和图18中特别所示地组装的,如以上在图2至图10的实施例中所述地,在分叉室的开口端处,分支保持器214与壳体110接合。所示的分支保持器214将分叉管106容纳在延伸穿过分支保持器的分支导向部220中。所示的分支保持器214包括单个分支导向部220,以接收成捆的所有分叉管106。例如,所示的分支保持器214可具有环形的几何形状。
所示的分支导向部220限定了由尺寸D2表示的间隙。示例性的尺寸D2可以在约0.250英寸(6.35mm)和0.500英寸(12.7mm)之间的范围内,优选在约0.300英寸(7.62mm)和约0.400英寸(10.16mm)之间,并且更优选地为约0.313英寸(7.95mm)。所示的分支导向部220可以具有圆形的几何形状,使得间隙尺寸D2代表直径。
所示的分支保持器214可具有与上述图4中所述的分支保持器114以尺寸X3表示的长度相同的长度。所示的分支导向部220的间隙D2优选地沿着整个长度X3是一致的。如图15所示,在相邻的分叉管106和分支导向部220的间隙表面之间留有未被占用的空间的空隙。
所示出的过渡组件200以与上述相同的方式并且根据相同的过程来制备。环氧树脂108也被填入分叉管106和分支导向部220的间隙表面之间的空隙中。一旦环氧树脂108的体积硬化,线缆104、壳体110、分支保持器214和分叉管106就变成了单个且坚固的个体。
在图19-26中示出了另外的示例性过渡组件300。所示的过渡组件300包括与如上所述的相同的壳体110和线缆104。所示的过渡组件300包括与如上所述的相同的分叉管106,但是,包括了更多数量的分叉管(例如二十四个)。所示的过渡组件300包括与如上所述的相同的光纤102,但是,包括了更多数量的光纤(例如二十四根)。所示的过渡组件300将每根光纤102单独地装配到分叉管106中,从而存在用于二十四根光纤的二十四个分叉管。
如图19-22和26特别所示地组装的,分支保持器314如上所述地在分叉室的开口端处与壳体110接合。所示的分支保持器314容纳延伸通过分支导向部320的分叉管106,其中该分支导向部延伸通过分支保持器。所示的分支保持器314包括单个分支导向部320,以接收成捆的所有分叉管106。例如,所示的分支保持器314可具有环形的几何形状。
所示的分支导向部320限定了以尺寸D3表示的间隙。示例性的尺寸D3可以在约0.250英寸(6.35mm)和0.500英寸(12.7mm)之间的范围内,优选在约0.400英寸(10.16mm)和约0.500英寸(12.7mm)之间,并且更优选地为约0.453英寸(11.5mm)。所示的分支导向部320可以具有圆形的几何形状,从而间隙尺寸D3代表直径。
所示的分支保持器314可具有与上述的由尺寸X3表示的相同的长度。所示的分支导向部320的间隙D3优选地沿着整个长度X3是一致的。尤其如图23所示,在相邻的分叉管106和分支导向部320的表面之间留有未被占用的空间的空隙。
所示的过渡组件300以与上述相同的方式并且根据与上述相同的过程来制备。环氧树脂108也被填入分叉管106和分支导向部320的间隙表面之间的空隙中。一旦环氧树脂108的体积硬化,线缆104、壳体110、分支保持器314和分叉管106就变成了单个且坚固的个体。
