Description

光纤通用托架装置和方法
发明背景
技术领域
本发明总体上涉及光纤组件,尤其涉及有助于在通信网络中选择电缆路线的光纤通用托架方法和装置。
现有技术
光纤逐渐用于多种宽带应用,包括话音、视频及数据传输。因此,光纤通信网络包括多个互连点,多根光纤在这些互连点互相连接。光纤网络还包括多个连接终端,其例子包括但不限于网络接入点(NAP)盒、架空电信盒、地下电信盒、基座、光学网络终端(ONT)和网络接口装置(NID)。在某些情况下,连接终端包括连接器端口,通常通过终端的外壁打开,其用于在从分配电缆端接的光纤和一根或多根预连接分支电缆的相应光纤之间建立光学连接,扩展的分配电缆、系绳电缆或支路电缆在此统称为“分支电缆”。连接终端用于容易地将光纤通信服务延伸到用户。在这方面,光纤网络被开发,其传送“光纤到路边(FTTC)”、“光纤到商业场所(FTTB)”、“光纤到家庭(FTTH)”及“光纤到建筑物(FTTP)”,总称为“FTTx”。
在电信基础设施装置中,FTTx装置例如用于交换、交叉连接和互连多种不同装置和/或技术的装备用于将多光纤主干电缆固定到支架、连接器壳体或人孔内。许多这样的装备可以是简单装置,如ty-wrap、Velcro、或用于将环氧树脂插头分叉或电缆固定到已安装的通信装置机架上或固定在连接器壳体中。连接器壳体使工人能按需执行所需维护和/或重新配置通信网络。然而,用Velcro就ty-wrap进行固定的已知方案非常麻烦。
因此,需要有助于工人将环氧树脂插头分叉快速固定到连接器壳体上和/或快速将其从连接器壳体松开的通用托架。
发明内容
一方面,托架组件包括具有可挠铰链的托架及连到托架上的分叉组件。
另一方面,提供了用于光纤电缆的系绳组件。系绳组件包括具有第一端和第二端的系绳电缆,所述第一端适于连到光纤电缆,系绳电缆包含多根光学上连接到从光纤电缆接入和端接的相应多根光纤的光纤,在系绳电缆的第二端处的分叉用于使系绳电缆的光纤分开及将所述光纤转变为至少一分叉支线,所述分叉支线具有第一端和第二端,所述第一端连到分叉,在分叉支线的第二端的至少一单个连接器端口用于接入光学上连接到从光纤电缆接入和端接的多根光纤的系绳电缆的多根光纤中的至少一根光纤,及连到连接器端口的壳体的一体化构件,其中一体化构件构造成连到托架上。
另一方面,产品线包括构造成可采用在数据中心中的第一分叉塞壳、构造成可采用在基座和地下盒中的至少一个中的第二分叉塞壳、及构造成可连到第一和第二分叉塞壳的一体化构件。
本发明的另外的特征和优点将在下面的详细描述中提出,且从该描述或通过实施如在此所述的发明进行验证,其中部分对本领域技术人员将显而易见,在此所述的发明包括下面的详细描述、权利要求及附图。
应当理解,前述一般描述及下面的详细描述呈现本发明的示例性及说明性实施例,及提供用于理解如权利要求所限定的本发明的本质和特征的概览或框架。提供附图以进一步理解本发明,且其与本说明书结合并构成本说明书的一部分。附图示出了本发明的多个示例性实施例,且连同说明书一起用于阐释本发明的原理和实施。

具体实施方式
现在详细参考本发明的优选实施方式,其例子在附图中示出。无论何时只要可能,相同的附图标记在所有附图中均指相同或类似部件。
图1所示为一体化构件10,其包括从构件主体14经居中位于主体14上的铆柱件16延伸的栓12。在第一端18上为第一锁定件20。在远离第一端18的第二端22上为第二锁定件24。弓形部分26使第二锁定件24能够偏向第一端18,如下结合图4和5所述。如图1中所示,锁定件24可偏转,而锁定件20不可偏转。然而,在一实施例中,锁定件20和24均可偏转。多个加固件28延伸在主体14的一侧30上。位于相邻支撑件28之间的是主体14上的多个紧固件开口34。通常,构件10由塑料模制成,并相当轻及相当便宜。然而,构件10可由不同于塑料的材料制成。
图2示出了位于将要安装到构件10上之处的分叉塞壳50。分叉塞壳50不可大小适于接受栓12的槽52。
图3示出分叉塞壳50包括多个紧固件开口54。在一实施例中,开口34具有螺纹以接收螺钉56,使得螺钉56首先通过开口32,之后通过开口54,然后与开口34接合从而将分叉塞壳54连到构件10上。或者,可使用不同于螺钉的紧固件,及开口32、34和54的大小可变以适应非螺钉紧固件。
图4示出一体化构件10与分叉塞壳50连在一起形成分叉组件60,其中分叉组件60位于将要安装到托架70上的地方,托架70包括多个接合开口72。托架70还包括多个固定开口74和可挠铰链76。
图5示出托架70与分叉组件60连在一起,其中第一锁定件20和第二锁定件24与开口72接合。用户压第二锁定件24及将第一和第二锁定件20和24插入穿过开口72,然后释放压力从而使第二锁定件24能回弹到其未压缩形态,这使组件60连到托架70上。
图5示出连到托架70上并由第一和第二锁定件20和24保持在一起的组件60。组件60和托架70共同形成托架组件78。
图6示出用于通信网络(未示出)的连接器壳体80。连接器壳体80通常采用在数据中心环境中。连接器壳体80包括位于其上的多个导路装置82。托架组件78安装在入口板组件84上。可挠铰链76使用户能以反时针方向(图7中的A方向)和顺时针方向(图7中的B方向)移动托架组件78。另外,铰链使能向上和向下运动。
图7为连接器壳体80的一部分和紧固件86的放大图。连接器壳体80还可有利地包括至少一护环88。同样,电缆入口板组件84可拆卸,使得大量较小直径的电缆能从旁边进入连接器壳体80,而不是小量较大直径电缆。在其它实施例中,电缆入口板不是具有护环的组件,而仅仅是可拆卸的电缆入口板。
另外,护环可放在上端口90中。多根电缆在托架组件78处可分别固定和消除应变。电缆从这里(托架组件78)向电缆入口板组件84进发以进入连接器壳体80的内部空间。护环88柔软且能变形,从而防止电缆接触刚硬边缘。在该例子中,电缆入口板组件84包括一个护环88,使得多根电缆可进入连接器壳体80的一侧。此外,电缆可从顶部、底部或二者进入连接器壳体。如果电缆从下面进入,应变消除托架组件可连接在连接器壳体侧板底部的附近。当连接电缆入口板组件84之后,连接器壳体80或适于通过护环88进入的小量较大直径电缆或适于通过护环88进入的相对有限数量的较小直径电缆。然而,连接器壳体80可具有比使电缆能通过护环88进入壳体提供的容量更大的容量,以用于组织和容纳光学连接。因此,护环88可拆卸以使得在护环拆卸后比护环处于适当位置时能允许更多的电缆进入壳体80。
在使用中,托架组件78有助于使工人快速组织、选路和保存光学连接如在连接器壳体80中接合或连接。另外,可挠铰链76有助于工人按需进行维护和/或重新配置通信网络。
图8所示为与2004年12月3日申请的未决申请11/003102中描述的系绳组件(20)类似的系绳组件120,所述申请全部组合于此。系绳组件120包括预选或定制长度的系绳电缆122,其适于在中跨接入位置连到分配电缆。在该示例性实施例中,系绳电缆122包含多根光纤并在分叉124中端接,所述分叉将系绳电缆122内的光纤分为多个独立的连接器端口128。每一连接器端口128使能接入系绳电缆122的至少一光纤,其与在中跨接入位置自分配电缆端接的至少一光纤互连。一体化构件10连到每一连接器端口的壳体从而形成多个分叉组件60,其中连接器壳体为分叉塞壳50。之后,分叉组件60可在现场安装到托架上。此外,分叉组件60可在现场安装到托架70上以形成托架组件78。分叉组件60可放在基座中、地下盒中或空中装置中(所有这些均非数据中心环境)。但图7中所示的系绳未被使用在数据中心环境中。因此,一体化构件使能产生分叉组件,其被构造成安装到数据中心环境及非数据中心环境中的托架上。单一一体化构件的使用使能降低仓储成本及有助于工人容易及适当地进行连接。
如图8中所示,每一连接器端口128包括用于接收安装在光纤端部上的光连接器的插孔130,其通过系绳组件120的分叉支线126路由到插孔130;每一连接器端口还包含已连接光纤电缆的插头132,所述光纤电缆如支路电缆或分支电缆,在下文中总称为分支电缆134。连接器端口128尤其是插孔130使能接入系绳电缆122的一根或多根已连接光纤,所述光纤光学上连接到在分配电缆的中跨接入位置接入和端接的光纤。连接器端口128可用于容易地使已连接光纤分支电缆134的光纤与分配电缆的端接光纤在光纤通信网络中的所需位置互连。如在此使用的,术语“连接器端口”意于广义地包括在系绳组件的分叉支线126的自由端提供的任何组件,其有助于将系绳电缆122的光纤光学上连接到已连接分支电缆134的光纤。在于此所示和所述的示例性实施例中,连接器端口128包括插孔130、插头(未决申请11/003102的图3-5中的42)及光纤连接器(未决申请11/003102的图8和9中的96、97)。然而,连接器端口128还可包括位于插孔130内的在工厂安装的转接器或连接器对准套筒或在现场安装的转接器或连接器对准套筒(例如,未决申请11/003102的图3和4中所示的对准装置46),其用于以反作用物理接触对准和保持配合连接器。在不同实施例中,连接器端口128还在分叉支线126的光纤和分支电缆134的光纤之间的光连接处提供环境密封。连接器端口128还可用于消除分叉支线126和/或分支电缆134的应变,其通过将施加到分叉支线126和/或分支电缆134的任何张力负荷按已知方式传给连接器端口128的结构(如壳体)实现。
系绳电缆122可以是具有预选或定制长度及包含一根或多根光纤的任何光纤电缆。如图所示,系绳电缆122包括适于在中跨接入位置连到分配电缆并构造成路由和保护分配电缆和分叉124之间的光纤的管状护套136。分叉124包括固定到系绳电缆122的下游端的不平主体。至少一最好多个独立的分叉支线126按已知方式通过环氧树脂材料固定在分叉124的主体内以形成常规分叉插头。分叉支线126可以是包含系绳电缆122的一根或多根光纤的任何类型光纤套、护套或电缆。如图所示,每一分叉支线126包括管状体,其连到分叉124处的系绳电缆122,系绳电缆122的一根或多根光纤在其中得以路由和保护。在一例子中,900微米光纤在具有更大直径如0.002英寸(2mil)的管状体内选择路线和受到保护。各个分叉支线126可具有相同的预选或定制长度,或可具有不同的长度以沿分配电缆的长度错开连接器端口128从而减小系绳组件120和分配电缆的组合直径。这样,“低剖面”的分配电缆组件可部署通过具有相对小内径或明显弯曲的管道或部署在常规架空绳套装备上。在一实施例中,系绳电缆122的上游端在中跨接入位置连到分配电缆,及系绳组件120(如系绳电缆122和分叉支线126)在工厂中可拆卸或可滑动地捆到分配电缆上,使得系绳组件120可沿分配电缆的长度滑动或可在现场部署之后从分配电缆去除。
在另一实施例中,连接器端口128可通过双料射出成型在其相应分叉支线126周围,分叉124可通过双料射出成型在分叉支线126和系绳电缆122周围以提供在室外环境中使用的不平及密封(即防潮)组件。双料射出成型也可用于将系绳电缆122的上游端在中跨接入位置连到分配电缆。双料射出成型工艺,也称为“注射造型”,包括按本领域公知方式准备系绳电缆122的护套136及分叉支线126,如通过清洁及糙化、火焰准备或化学方法准备表面以促进与双料射出成型材料的摩擦和附着。插孔130(包括它们相应的光连接器和光纤)、分叉支线126及系绳电缆122的下游端悬置在适当的双料射出成型工具内,及双料射出成型材料灌注或注入到双料射出成型工具内,使得双料射出成型材料包围和密封插孔130、分叉支线126和系绳电缆122的下游端。在备选实施例中,保护层如但不限于由锡或铝制成的箔可用于在双料射出成型之前保护插孔130、分叉支线126及系绳电缆122。然而,其它材料也可用于在双料射出成型之前保护下面的组件,假定所述材料能够成形为与所述组件的外轮廓一致。
一旦所述组件已被适当地保护(如果需要)并置放在双料射出成型工具的第一部分内,双料射出成型工具的第二部分可与第一部分连在一起以形成用于接收双料射出成型材料的内腔。双料射出成型材料的适当例子包括但不限于聚氨酯、硅酮等粗糙但柔软的材料。双料射出成型材料灌注或注射到双料射出成型工具形成的内腔内。双料射出成型材料提供保护壳、保持密封完整性并最好能够承受高达至少约300lbs的压力。由于双料射出成型工艺,连接器端口128和分叉124具有光滑、低剖面形状,外部呈圆形或锥形,以避免在部署分配电缆和系绳组件120通过管道或架空绳套装备期间绞结。
图8中所示系绳组件120的实施例包括四个分叉支线126及连接器端口128,其用于将系绳电缆122的光纤光学上连接到一根或多根分支电缆134的光纤。然而,其它实施例具有不同于4个的多个分叉支线126。系绳电缆122的光纤继而与在中跨接入位置接入和端接的分配电缆的光纤互连。因而,本发明的系绳组件120用于使分配电缆的端接光纤与一根或多根分支电缆134的光纤互连。在示出四个一样的分叉支线126和连接器端口128的同时,可以预见,系绳组件120可具有任何数量的分叉支线126及任何数量的连接器端口128。还可预见,系绳组件120的每一分叉支线126可端接一个以上的连接器端口128。此外,分叉支线126和/或连接器端口128可进行颜色编码或提供其它标记以识别系绳电缆122的特定光纤,因而识别分配电缆的特定端接光纤。另外,不同的端口128可用于不同类型的连接器。
在使用中,系绳组件120可容易地安装在基座或地下盒中。另外,当一体化构件10连到托架70时,可挠铰链76有助于工人容易且快速地将连接器端口128定位在所需位置。
图9示出壳体150包括罩152,其中多个托架组件78安装到支撑件154上。应注意,托架组件78在相对小的空间中形成方便的阵列并有助于工人非常容易地修改网络连接。所述修改或为进行新的连接或为重新选择现有连接的路线。
本领域技术人员应意识到,在不背离本发明精神或范围的情况下,可对本发明进行多种修改和变化。因而,本发明意于覆盖所提供的本发明的修改和变化,它们均在所附权利要求及其等效方案的范围内。
