Description

具有多个一体形成的适配器的光纤适配器模块
技术领域
本发明涉及一种光纤通信器件。更具体的,本发明涉及一种光纤模块和用于保持该光纤模块的机壳。
背景技术
在光纤通信系统中,常见的是将传输光纤线缆分为多束,可以通过对由单个线缆束传送的信号进行光学分束或者将多束线缆的单个光纤束扇形分叉(fanning out)。此外,当装配这样的系统时,已知需要提供在装置内额外的容量用于光纤的未来发展和使用。通常在这样的装置中,包含分束器和扇形分叉(fanout)的模块被用于提供在传输光纤和用户光纤之间的连接。为了减少初始装置的成本和复杂度并提供未来扩容的选择,可安装多个模块的模块安装机壳可以被用在这样的装置中。
当机壳可以接收若干模块时,初始装置可以只包括少数几个安装在机壳内的模块,或者足够当前需要的数量。这些机壳可被设计成有限地接近一个或多个侧面,或者被安装在狭促的位置。并且,一些这样的机壳可以被预配置为具有用于容纳和连接未来安装的模块的最大容量的传输线缆。由于希望在安装新模块时可接近机壳内的部件以便进行清洁,因此机壳的一些设备或特征最好能够允许操作者接近和清洁这些预连接和预安装传输线缆的连接器。
同时,希望机壳被设计成确保模块准确安装并与机壳内其它部件对准以紧密配合预连接和预安装的传输线缆。
发明内容
本发明涉及一种光纤适配器组件,该组件包括多个包含在一体形成的主体中的适配器。每个适配器可以包括安装在一端内的保护闸片。该适配器组件可被设计成安装到机壳上并且定位适配器以接收安装在机壳上的通信模块的光纤连接器。

具体实施方式
附图标记被用具体于本发明的示例性描述,其在附随的附图中示出。在可能的情况下,同样的附图标记在所有的附图中用于代表同样或相似的部件。
附图1示出了通信组件10,其具有用于安装多个模块14的安装位置12。组件10包括机壳或壳体16,机壳或壳体16包括第一主侧面18、第二主侧面20和一对在第一和第二主侧面之间延伸的相对的横向侧面22。安装法兰24可以被安装在每个主侧面上大致彼此相反地延伸。第二或可选择的安装法兰26也可以被安装在其中一个主侧面上从而提供将壳体16安装到特定尺寸或形状的设备架、箱体或其他类型的装置上的选择。
壳体16限定了前开口28,模块14通过前开口28插入到壳体16的内部30(在附图7的下半部示出)。在横向侧面22上可限定开口32以允许操作者进入内部30。开口32在其周边可具有保护垫34,以防止当通过一个开口32进入或离开内部30时对手造成擦伤或其它伤害。从图1中的开口32可以看到安装在前开口28内的一个模块14的壳体40。法兰24和26可以包括多个用于将壳体16安装在通信装置中所需要的位置的紧固孔36。
参见附图2,每个模块14包括临近第二主侧面20的可释放的锁杆42。如附图10中下半部所示,锁杆42与壳体16的一部分啮合从而保持模块14在前开口28内,并且,锁杆42可以被偏转以允许模块14从壳体16撤回。每个模块14也可以包括一或多个从前表面46延伸出的线缆出口44。线缆出口44使得模块14内的通信线缆被导向到模块14的外部,如将在下面结合图10的描述。如附图2中所示,模块14的前表面46与前开口28成一定角度,其可以帮助从模块14出来的线缆向着通信装置中希望的方向。在本发明公开的范围内可以预见,前表面46可以被制成在前开口28处基本平行于横向侧面22的前边缘38。
参见附图3,模块14包括不同长度的法兰48和50,它们分别被接收在相应尺寸的狭缝52和54内。法兰48和狭缝52的尺寸比法兰50和狭缝54的尺寸小。狭缝52的尺寸使得法兰48可被接收在狭缝52中,而较大的法兰50不能被安装其中。如此确保模块14被定位在前开口28所希望的方向上。类似的法兰在公众享有的美国专利NO.5,363,465中有所描述,其公开的内容作为参考引用在此。通过翼形螺钉58可释放地保持在前开口28内的适配器保持件56与锁杆42相反地在每个安装位置12处安装至壳体16。参考附图9至16,适配器保持件56将在下面被进一步地具体描述。
参见附图4和5,壳体16进一步地包括和前开口28相反的后表面60,其基本封闭了壳体16的后部。可以提供穿过后表面60的开口以允许线缆和气流通过,但是期望操作者通过前开口28进入壳体16的内部30。如附图6中所示,在模块14的一端上,可以包括边缘或手指抓握部62用于帮助将模块14从壳体16中移出。手指抓握部62优选地位于模块14上与锁杆42相反处,使得操作者可以使用手指或手的相对的力量来安全地抓住模块并将其移出壳体16。
参见附图7,模块14的锁杆42可以包括凹入区域66,其与安装位置12的边缘64啮合以保持模块14在前开口28内。凹入区域66形成在临近锁杆42的末端处,柔性部件68从凹入区域66延伸至与模块14的第一侧面70连接的位置。柔性部件68可弹性变形,并且允许操作者偏转锁杆42使得凹入区域66与边缘64解除啮合并从壳体16中去除模块14,或者当模块14插入到前开口28中时将锁杆42偏转并与边缘64啮合。模块14包括第二相对侧面72和后部78。中间的后表面76通过插入侧面部件74被形成在第二侧面72内。一对光纤连接器80位于后表面76内,用于与安装到壳体16内部30内的适配器保持件56上的光纤适配器相配合。
模块壳体40还包括第一横向表面82,其在第一侧面70、第二侧面72、后部78和前表面46之间延伸。第二横向表面84封闭了模块壳体40在第一表面46和后部78之间的相对的侧面,但是延伸至侧面70和72之外以形成法兰48和50(法兰50在附图7中未示出)。在附图8中,法兰50作为第二横向表面84延伸到模块14的侧面70之外的延伸部是可见的。模块壳体40可包括位于侧面70、72和后部78之间的弯曲过渡部86。过渡部86的形状使其在线缆延长至适配器88时对内部30的线缆提供弯曲半径保护。可选择的,侧面70和72可以直接终止在后部78处,取决于在模块壳体40内安置部件的需要和制造模块壳体40的效率。
附图9中示出了组件10,其具有从内部30中分离出的适配器保持件54。保持件54包括延伸部86,用于保持和定位一对适配器88使它们与模块14的连接器80啮合。每个适配器88包括第一端或后端90和第二端或前端92,并且每个第一端和第二端适于接收可端接光纤线缆的光纤连接器。
图10示出了组件10的横截面图,其具有从连接器80延伸至光学部件98的第一线缆94,第一线缆94安装在模块壳体40的内部96中。光学部件98可以是分束器或者扇形分叉或者其它类型的主要光学元件。第一线缆94可以是具有多个光纤束的多束光纤线缆,光学部件98可以是扇形分叉,用来将单独的多束分离成多个第二线缆100中的每一个。第二线缆100从光学部件98延伸至线缆出口44。可选择的,第一线缆94可以是单个光纤,其信号被作为分束器的光学部件98所分离,并从承载来自第一线缆94的部分信号的多个第二线缆100可以延伸至线缆出口44。光纤的设置和线缆出口44处的罩子在公众享有的美国专利申请NO.10/658,802中有所描述,其公开的内容作为参考引用在此。
外部线缆102可以延伸至适配器88的后端90并且端接于连接器104。连接器104可以被接收在后端90中以便被光学连接到模块14连接80上。线缆102可以从壳体16的内部30延伸通过壳体16的侧面18、20或22上的开口。
参见附图11,组件10的一个模块从一个安装位置12移除,并且在该安装位置12处包括可替代的适配器保持件154。保持件154包括防护盖108,其位于适配器88的第二端92的前面。在一些装置中,在模块14被置于相关的安装位置12之前,壳体16可以被装设并且线缆102被导向和连接到适配器88的第一端90。如果线缆102被光源照明并传输光信号,防护盖108可以保护这些信号的意外曝光,这种意外曝光可能对眼睛、或其它敏感器件或者附近的通信装置造成伤害。
在附图12中,保持件154包括穿过延伸部86的开口124,通过所述开口安装适配器88。翼形螺钉56延伸通过前法兰114,并且一对壁配合法兰116从相邻的前法兰114向后延伸。可选择地,其它可释放的零件,如卡合装置、直角转弯紧固件、膨胀锁杆或者相似的零件可以替代保持件54或154上的翼形螺钉56使用。在每个法兰116的前端和前法兰114之间具有狭缝118。朝向法兰116的后端具有一对壁狭缝120。如附图10中所示,内壁110位于内部30中从第一主表面18向内偏移。壁狭缝120沿着内壁110的两侧延伸。第一主表面18的内折的前边缘112与狭缝118相配合。壳体16和保持件154之间的配合使适配器偏离内部30中的内壁110正确定位,从而使其与模块14的后表面76上的连接器80相配合。中心部件122从位于壁法兰116之间的前法兰114延伸至延伸部86,从而正确地将适配器88安装在前开口28和后部60之间的内部30中。
参见附图13至16,保持件154的延伸部86包括多个用于安装适配器88到延伸部86上的紧固孔124。紧固件126可以被延伸通过适配器88的侧法兰128以实现稳固地安装适配器88。适配器88被示为SC型连接器,虽然其它类型和形式的适配器也可以在本发明公开的范围内使用,连接器80和104被改变以配合这些可选择的适配器。示出的每个适配器88内可以有一对准装置(例如裂隙套筒130),用于正确地定位端接于套圈并且由连接器80和104所支撑的光纤。如上所述的对准装置和端接套圈属于现有技术。
从侧面看防护盖108是弯曲的,如附图15中所示,这样当模块14通过前开口28被插入到内部30中时,防护盖108可以被模块14偏转从而连接器80和适配器88紧密配合。防护盖108优选地由弹性材料制成,当模块14从安装位置12撤回时,其可以恢复到如附图15中所示的位置。防护盖108可以通过一对例如螺钉132的紧固件连接到中心部件122上。可选择的,防护盖108可以通过由保持件154一体地形成或者通过点焊或其它紧固技术被连接到保持件154上。因为后部60封闭了壳体16的后部,所以没有通到安装在安装位置12处的任何模块14的后部的通路,如图所示没有必要再设置第二防护盖108用于阻挡来自每个适配器88的第一端90的光线。但是,如果任何敏感器件安装在模块14或壳体16内,最好安装有第二防护盖108用于阻挡适配器88的第一侧90。
将模块14插入到壳体16的一个安装位置12处可以包括首先松开翼形螺钉56并通过前开口28从内部30中移出保持件54或154。线缆102优选地在内部30内包括有足够的额外长度或松弛度从而允许适配器88从开口28被拉出。一旦位于内部30以外,线缆102的连接器104可以从适配器88的第一端90移出从而可以清洁线缆102中光纤的抛光端面。然后连接器104可以被重新插入到第一端90中。保持件54或154可以被重新插入到内部30中,以使得该保持件与内壁110和内折延伸部112相配合并重新固定翼形螺钉56。模块14插入到前开口28使模块14配合到壳体16和适配器88。当模块14插入时,法兰48和50与狭缝52和54分别配合。当连接器80接近适配器88的第二端92时,连接器80和部分第二侧面72配合并偏转防护盖108(如果有的话)。进一步插入模块14将连接器80引入并使其与适配器88相接触,并且所述连接器被接收在第二端92内。当模块14被插入时,锁杆42被向内偏转然后弹回,使得凹入区域66与边缘64配合。模块14在安装位置12处被安装在前开口28和内部30内,并且位于适当的位置处,以通过模块内部96的第一线缆94、光学部件98和第二线缆100处理和传输来自线缆102的信号。
参见附图17至19,可选择的通信组件的实施例200包括多个安装在机壳204前部214内的安装位置206处的光纤分束器模块202。机壳204包括顶部208,一对相对的侧面210和一对从靠近前部214的侧面210向外延伸的安装法兰。机壳204还包括后部216。前部214限定了一对竖直堆叠结构的安装位置206,其彼此从前向后偏移从而改进了从模块202延伸的光纤线缆的线缆通路。
附图20至26示出了组件200,其具有安装在安装法兰212之一上的线缆管理结构220和底部218。两个模块202从安装位置206被移出。具体参见附图21和22,每个模块202包括多达四个后向连接器226,它们被接收在定位于每个安装位置206处的适配器组件222内。如图所示,机壳204的后部218对于延伸至适配器组件222后侧的光纤线缆是开放的,并且在临近后部218处安装后部线缆保护器以帮助这些后部进入的线缆导向到适配器组件222。每个适配器组件222包括多达四个光纤适配器232,其具有在前端接收后向连接器226之一和在相反端接收从后面进入的光纤线缆的连接器的结构。
参见附图27至31,每个安装位置206包括一对相对的狭缝228,当狭缝228与从模块202的侧面延伸的法兰230配合时定位模块202的连接器226使其与适配器组件222配合。
附图32至35示出了从机壳204移开的适配器组件222。适配器组件222包括四个一体的适配器232,并且每个适配器具有后端234和前端236。如图32和33中所示,防尘塞238位于每个后端234中并且延长的双防尘塞240被插入到每对适配器232的前端内,用于将适配器232的内部和污染物隔离开。适配器组件222包括适配器壳体部246和机壳安装滑道248,壳体部246内部安设有适配器232,该机壳安装滑道通过前端214接收在机壳204内并且和机壳204相配合用于确定安装位置206。法兰250从安装滑道248延伸,并且,用于将适配器组件222固定在机壳204内的翼形螺钉252通过法兰250延伸。螺钉252位于孔254内,并且优选地是系留紧固件,虽然其它的紧固件也是可以使用的。
如图33所示,每个适配器232位于壳体部246内。适配器232的元件定位为通过开口256进入适配器凹部258。每个适配器232的元件包括套圈对准套筒(ferrule alignment sleeve)260和一对内壳体半部262。这些元件位于凹部258内的方式与公告于1993年5月20日的美国专利NO.5,317,663相似,其中公开的内容作为参考引用在此。面板264封闭了开口256并保护每个适配器232中的元件。
参见附图36至41,闸片244位于每个适配器232的前端236中的前开口266内以提供意外曝光的保护。与闸片244相似的闸片在公开于2003年11月12日的PCT公开号WO 03/093889A1中有所描述,其公开的内容作为参考引用在此。闸片244滑入壳体部246中的狭缝268内。突出部270从闸片244延伸出并与突出部凹部272相配合以便将闸片244在每个适配器232中保持就位。当闸片244对于适配器232连接光纤线缆的功能不必要时,它也可以提供防止对操作者或其它仪器造成伤害的意外光信号曝光的保护。优选地,闸片244不与插入到每个适配器232中的连接器套圈配合。而是,连接器壳体将闸片244推出。
附图42示出了将入口面板264移除以示出凹部258内每个适配器232的元件的适配器组件222。
附图43示出了分束器模块202,其具有用于与机壳204内的安装位置206的狭缝228相配合的侧法兰230。连接器226被安装到位于模块主体280的前部276和后部278之间的插入壁板274上。螺纹盖(screw cover)法兰282从主体280的一对侧面284之一延伸出,并且锁杆42从另一侧面284延伸出。当模块202被安装到机壳204中时,法兰282延伸过适配器组件222的螺钉252。这样就防止了当模块202被安装在安装位置206处时,适配器组件222被移动或者螺钉252松开。线缆出口44提供从主体280内通过前部276的光纤通路,因此光纤可以延伸通过线缆管理结构220并且延伸到其它通信器件。
参见附图44,模块202包括由主体280和可移开的底板288确定的内部286,底板288被多个可移除的紧固件(例如螺钉290)保持到主体280上。一对光纤固定器292安装在内部286内临近每个线缆出口44的后面。如之前所描述的模块14,模块202优选地容纳分束器,其在一端接收单个光纤束并在另一端接收多个光纤束。模块202包括多达四个后向连接器226,并且因此可以包括多达四个分束器(附图44中未示出)。在内部286中,每个连接器226可以包括带角度的应变消除套227用来实现端接于连接器226的光纤的方向改变。
通过主体280上的开口292从内部286的外部可接近连接器226。连接器安装块296与连接器226间隔开并确保连接器226与适配器组件222的适配器232接触并配合。安装块296还包括上部线缆导向装置298,该装置用于在内部286中连接器226和出口44之间布置线缆。在内部286内还可以包括分束器装配件300,用于定位和固定模块202内的一个或多个光学分束器或其它光学部件。中心支撑杆和螺纹座302也可以被安置其中从而提供对底板288的额外的支撑。手指抓握部或把手304从前部276延伸出以提供方便的抓握,用于将模块202从机壳204移开,或者帮助操作。
参见附图45至51,模块202包括大深度部分306和浅深度部分308,大深度部分306临近前部276,并且连接器226将进入的光纤导向其中,浅深度部分308从临近连接器226处开始一直延伸到后部278。可安装在模块202上的连接器226的数量不允许侧面284朝向彼此移动,减少了内部286的宽度,不会侵占内部286内太多的线缆布线空间。部分深度部分308从后部278延伸至连接器226使得适配器可以与主体280重叠,这对于如上所述的模块14是不可能的。减少的深度确实减小了内部286的体积但是不会对内部286内的弯曲半径要求有不利影响。过渡部件310提供在部分306和308深度之间的平滑过渡。平滑过渡可以很好地减小光纤在内部286内可能遇到的尖锐角度,并且使得形成或制造主体280更容易。
在模块202中,连接器226位于主体280的顶部到底部范围内,即,在侧面284之间,并且从模块202的最靠后延伸部插入,例如,后部278。
模块202被设计成当适配器组件222被定位和连接到线缆上时能够从前部被安装在机壳204内,而不需要触及任何后部连接器。松开所述螺钉252以牵引组件通过机壳204的前部214可以提供到线缆和连接在适配器组件222后端234的通路,因此可以接近这些连接器对其进行观察或清洁。
上述具体描述、示例以及数据给出了本发明使用和制造的详细描述。由于本发明的很多实施例可以在不偏离本发明的范围和精神作出,因此本发明包涵在由附随的权利要求所限定的发明的范围内。
