Description

独立的光导纤维连接器模块
技术领域
本发明涉及光导纤维传输技术,特别涉及一种独立的光导纤维连接器模块。
背景技术
种类繁多的光导纤维连接器被用来终止光导纤维电缆以及便于使光缆和其它光缆或其他光导纤维传输设备连接。典型的光导纤维连接器包括在连接器内集合并固定一条光导纤维或多条光导纤维的套盒。套盒可以由陶瓷之类的材料构成。连接器的套盒支架或其它壳体组件环绕套盒并可以由模制塑料之类的材料制成。在框架或套盒支架内可设置一弹簧,使套盒向前偏转以接触另一相匹配的连接设备上的光纤安装套盒。
一对光导纤维连接器或一个光导纤维连接器和另一个光导纤维传输装置常常在一适配器中连接,该适配器使光纤集中以保证低介入损失。适配器将连接器配对,使其中包裹的光纤端对端连接在一起。适配器可以是一个嵌入组件,也可设计为能安装到面板、底板或电路板之类的开口中。
在设计光导纤维连接器组件或其它连接器组件时会不断遇到各种问题,包括如何在底板、母板、子板之类设备上的应用的问题。此类问题包括在印刷电路板之类基板上适当地精确地安放连接器组件,在连接器连接时调整其中的对准不当,允许系统不同部件之间相对移动以及其它类似的位置问题。其它问题则包括如何简化连接器组件的设计。本发明的目的就是为了解决上述问题,对此类连接器组件做出各种改进。
发明内容
本发明的目的是要提供一种新的改进的光导纤维连接器模块。
在本发明的例示实施例中,该模块包括一终止至少一根光导纤维的套盒。套盒包括一前接合端和一后端。一插针夹头与套盒后端接合。至少一条校正插针从插针束伸出穿过套盒,从套盒前接合端伸出以有效连接匹配的连接装置。在插针束后有一推力元件。在推力元件和插针束之间夹着一个弹簧。弹簧两头分别固定连接推力元件和插针束,使整个模块成为一个独立整体。
正如在此所述,该插针束和推力元件各有一容纳弹簧相对端部的插孔装置。该弹簧为一卷簧,插针束和推力元件在其插孔内均有锁定凸缘,用以在卷簧相对两端锁住弹簧线圈。
本发明的其它特征包括:该推力元件具有一锁定装置,用于锁定与匹配的连接装置连接的模块。较佳地,该卷簧的横截面为椭圆形,有助于将弹簧锁定于插针束和推力元件的锁定凸缘上。
本发明的另一特征是包括一光纤连接器模块,该光导纤维连接器模块具有一朝前的接触面,其接触套盒的平整的横向接触面,且呈圆形的凸起。
本发明其它的目的、特征和优点可以配合附图由以下的详细描述而知。

具体实施方式
依据附图详述,先看图1-3,本发明体现为匹配连接器组件,标号为24,包括一底板连接器组件,标号为26,接合一子板连接器组件,标号为28。底板连接器组件安装在基板、电路板或底板(在较佳的实施例中是印刷电路板)的开孔30内。特别地,底板32在这里可认为是“母板”,子板连接器组件安装在另一块印刷电路板34(在这里可认为是“子板”)的上表面上。
底板连接器组件26包括一适配器,标号为36,其安装在母板32的开孔30中。四个光导纤维连接器模块,标号为38,从底板32的前面穿过开口30插入适配器36。每个光导纤维连接器模块都在多线光缆40处终止。每条光缆都是扁平即“带状”的光缆,其中包含多条光导纤维。
当子板连接器组件28安装到子板34上之后,四个光导纤维连接器模块,标号为42,插入连接器壳体的后面,正如随后所述的。每个光导纤维连接器模块42都在类似光缆40的多线光缆44处终止。底板连接器组件26与子板连接器组件28可沿着箭头“A”的方向对接(图1和2),最终完成连接(见图3),其中光缆40和44中的光纤发生功能性连接。
如图4所示,适配器36包括一个由模制塑料材料构成的壳体46。该壳体形成一前接合端46a和一后终止端46b。前接合端在46c处敞开,光导纤维连接器模块38的套盒(见下文)能从中穿过伸出。后终止端46b在46d处敞开,能接收由箭头方向“B”而来的连接器模块38。适配器36的壳体46在其相对的两边各有一向外突起的定位肋48,其顺着连接器组件的接合方向伸展,其目的见下文所述。
图5示出了用于闭合适配器46开孔46b的闭合器组件,标号为50。图6示出了用于闭合适配器配合孔46c的闭合器组件,标号为52。闭合器组件50包括一对弹簧式闭合器50a,用于关闭内隔板54(图4)相对两边的开孔46d。闭合器元件可转动地装在平板50b上,平板包括多个能压配合入适配器壳体46的洞56中的桩子50c。同样地,闭合器组合52的闭合器52a是弹簧式的,装在平板52b上,平板包括多个能压配合入适配器壳体46的洞56重的桩子52c。闭合器50a和52a为适配器36的内部提供防尘罩。
接合图4来看图7,其中提供了将适配器36安装到底板32上的装置,以期在两者之间提供相对的移动。特别地,一对T形螺母,标号为60,不固定地安装在适配器36内,其可容置一对沿着箭头“C”穿过底板内的一对安装孔64而插入的铆钉62。该铆钉具有放大的头部62a以铆住底板的表面。该安装孔64间隔开位于开孔30的两侧。
另外,每个T形螺母60包括一杆部60a和一放大的头部60b。一安装凸缘,标号为66,与适配器壳体46的相对两侧一体成型。每个凸缘66包括容置一个T形螺母60的头部60b的内腔66a。通孔66b贯通凸缘66朝底板32延伸连通内腔66a,以容置T形螺母的杆部60a。请明确以下参数:(a)头部60b的尺寸比内腔66a小,这样头部能在腔内滑动,(b)杆部60a的横断面尺寸比通孔66b尺寸小,这样杆部就能在通孔内滑动,和(c)杆部60a的长度大于凸缘66的壁部67在头部之下的厚度(即图7中双箭头“D”指示的厚度)。这样,当铆钉62将T形螺母铆紧到底板32的表面32a上时,适配器并没有被铆紧到底板上而是能在其上作相对滑动。最后,通孔66b具有一限制口66e,这样T形螺母能被卡入凸缘66中而由此被安装入适配器壳体46。请注意铆钉62同样可以是有螺纹的接合件,比如螺丝钉,以此螺纹咬合T形螺母上的螺纹。
图8-10示出了如上文所述插入适配器36的一个光导纤维连接器模块38。特别地,每个模块38包括一套盒68,该套盒终止到一条多线光缆40,光纤末端40a(图8)在套盒接合面68a处暴露。套盒包括在接合面68a开口的一对校准孔68b。套盒被一手动调节的壳体70包裹,该壳体包括一实际包裹套盒的前部70a,和一后部,后部由一对可握持在操作者指间的横向间隔的臂70b构成。由图10可见套盒68具有一外围凸缘68c。壳体70的前部70a包括一对在壳体两相对边的向前的锁定钩70c,以及在壳体另两相对边的一对柔韧的锁定臂70d。如图9所示,每个锁定臂70d包括一个内置的有斜面的锁定钩70e。锁定钩70c和套盒凸缘68c的前部接合,而锁定臂70d的锁定钩70e与凸缘68c的后部边缘接合,将套盒包裹于壳体70的前部71之内。
在参见图8-10,可手动操作的臂70b在其外面具有锯齿状突起70e以辅助手动握持。一锁定块70f从至少一个上述臂上向外凸起,从内部锁定接合适配器36。每条臂70b还设有一条内部通道70g使套盒68沿着通道进入壳体前部70a。另外,该对可手动操作的臂中的一条臂上有一切除区70j。
如图所示,该切除区70j使臂的边墙变窄。当两臂被捏住并被压到一起,具有切除区70j的臂要比没有切除区的臂更具柔韧性。使臂具有这样一个切除区的一个特别的优点是,该带有锁定块70f的臂向内发生巨大弯曲,足以使锁定块70f相对容易地在适配器36中解除接合。就在锁定块70f之前设置一最深的切除区70j能使上述的脱离更加容易。在脱离过程中,在某种意义上,这使得带有切除区70j的臂部分被隔离,从而施加较小的力能使其弯曲更大的角度。请注意,例示实施例的切除区70j以不常用的手法形成,所以该切除区最深的地方是在斜面的底部。这样,在分离中施加的力就分布在整个边墙上,这就防止了连接器断裂。同时,如上文所述,这提供了更大的弯曲度和更容易得到的柔韧性。针对不同的要求也可使用其它形状和深度的割除区。
图10描绘了套盒68能沿着箭头方向“E”插入连接器模块38的壳体70中。套盒在臂70b的通道70g中移动,并通过壳体前部70a的开放后端70h。套盒在一个突出于壳体的开放前端70i(图9)的位置锁定,被锁在如图8显示的位置,套盒向前突出于可手动操作的壳体。
图11-13描绘了子板连接器组合28,其中的两部件壳体由一前壳体部件72和一后壳体部件74组成。后壳体部件74能沿着箭头“F”(图11)的方向插入前壳体部件。后壳体部件74具有一带锁定钩74b的柔软的锁定臂74a,当两壳体部件被组装在一起时,该锁定钩在一锁定肩部72a后起到锁定作用(图13)。图13中还显示了处于锁定肩部72a之后的另一锁定肩部72b,其作用如下文所述。每个壳体部件72,74均以塑料之类的绝缘材料整体压模制成一体构件。
通常会有一种系统,使子板连接器组合28的前壳体部件72非常精确地安装到子板34上。特别地,子板上有一个位于一对定位孔78之间并隔开的预置孔76,见图11。一对铆钉80插入定位孔78。如图12所示,从前壳体部件72的底面72d向下伸出一预置定位桩82,几乎不用力就可将其插入预置孔76。换而言之,孔76比桩82大。通过压配合将底面72d向下伸出的一对定位桩84插入子板34的定位孔78,使壳体精确地固定在基板上。桩82是实心的,而桩84是空心的,铆钉80穿过其中将前壳体部件铆定于子板上。预置的桩82比定位桩84长,这样操作者就容易将预置桩82对准并插入预置孔76。于是壳体就能容易地绕桩82转动直至定位桩84对准定位孔78。
仍参照图12,定位桩84在其外部带有可压碎的肋84a,当桩84被揿入孔78时肋能被压碎或者变形。前壳体部件72的底面72d围绕每个定位桩84的区域86是凹陷的。凹陷区域用来容置任何类似可压碎的肋84a的塑料材料,当定位桩84被压配合入定位孔78时,其上的肋就可能被刮下。这保证了前壳体部件72的底面72d被平整地安放到子板34的顶部平面上。
在子板连接器组件28和底板连接器组件26的适配器36之间通常设有一套对齐系统。具体地讲,如图11和12所示,前壳体部件72在其开放接合端72e的两相对侧设有一对对齐凸缘88。每个凸缘有一个向外倾斜或向外展开的末端88a,该末端在两个连接器组件接合时与适配器36的前缘90接合(图1)。特别地,向外展开的末端88a允许连接器组件在大致垂直于连接器接合方向“A”的“X”方向发生一定程度的对齐不当(图1)。“X”方向大致与子板34平行。对齐凸缘88在其里面有凹槽或狭槽88b以接收适配器46两边上的定位肋48(图1)。狭槽88b具有向外展开的口88c与定位肋48的末端接合,这样就允许两个连接器组件在大致垂直于接合方向“A”(同时大致垂直于前述的“X”和子板44)的“Y”方向发生一定程度的对齐不当。这样,对齐凸缘88,包括向外展开的末端88a以及与之配合的狭槽88b上的向外展开的口88c,能用一种结构在两个不同方向“X”和“Y”上允许发生一定程度的对齐不当。
参照图11和12再看图2,一个底部凸缘92从前壳体部件72向前伸出与前壳体部件的底面72d齐平(图12)。该凸缘具有一底钩92a和一顶部斜面区域92b。底钩92a与子板34的边缘94重叠。顶部斜面区域92b与适配器壳体46的底部前缘接合,防止壳体的底部前缘在连接器组件接合时“戳坏”子板的前缘。
图14-19显示了插入到子板连接器组件28的后壳体部件74中的一个光导纤维连接器模块42的具体细节。特别地,每个模板42包括终止多线光缆44的套盒96,以及消除电缆应变的弹性保护罩98。该套盒包括一对通孔或通道96a(图15)以容纳一对校正插针100,插针固定在插针夹头102中,插针夹头抵靠套盒96的后部,这样校正插针100的末端就可向前穿过套盒96的前接合面96b。如下文所述,在插针夹头102后端固定有一卷簧104,在卷簧后端固定有一弹性推力元件106。插针夹头102和推力元件106均由合成塑料或模制塑料制成。一个完整有弹性的锁定臂107从推力元件向外伸出,在子板连接器组件28的后壳体部件74内锁定光导纤维连接器模块。图16显示在插针夹头102后端有一插孔102a以容纳卷簧104的前端,同时有一锁定凸缘102b在弹簧的前端锁住弹簧线圈。尽管无法从图16中看到,在插针夹头102的插孔102a相对的两边各设有一锁定凸缘102b。
同样地,图17显示了一个推力元件106,在其前端设有前插孔106a以容纳卷簧104的后端。在插孔102a相对的两边各设有一锁定凸缘106b,以便在弹簧的后端锁住弹簧线圈。
图18和19描绘了在插针夹头102和推力元件106之间组装卷簧,以及将卷簧固定到这些元件中的过程,请注意卷簧104的横截面是椭圆的。工具110具有一条大致椭圆的轴112,能沿着箭头“G”的方向插入椭圆的卷簧104。然后顺着箭头“H”的方向旋转该工具,能有效地旋转卷簧,使前开口端线圈104a锁定在插针夹头102的凸缘102b(图16)之后。该子组件被调整到如图19所示的位置,这样的另一开口端线圈104b(图18)就与推力元件106的锁定凸缘106b对齐。然后将工具110的轴112沿着箭头“I”的方向(图19)插入插针夹头102内的长方形洞114和卷簧104内,然后顺着箭头“J”的方向旋转该工具,这样能有效地将卷簧锁定到插针夹头和推力元件之间的位置。接着校正插针100将固定在狭槽116(图19)中,这样如图15所示从插针夹头向外伸出。然后将保护罩98插入插针夹头的孔114中,而套盒96则安装到校正插针100上;光缆44顺着箭头“K”的方向(图15)被插入并穿过整个组件;在套盒中,用环氧树脂粘合校正插针和光缆,这样就形成了图14所示的整个独立模块。
当底板组件安装到底板或母板32上,子板连接器组件安装到子板34上之后,图20-22描绘底板连接器组件26与子板连接器组件28沿着箭头“A”的方向的接合过程。这些图也描绘了光缆40连接到另一基板或板120上。在连接之前,图20显示底板连接器组件26的适配器36在相对的两边带有一对制动臂122,制动臂122的末端形成一锁定钩122a和一朝前的斜面122b。
底板连接器组件26与子板连接器组件28分两步接合在一起,分别如图21和22所示。第一步,制动臂122的锁定钩122a从后面卡住子板连接器组件28的后壳体部件74的一对预锁肩124(图1和20)。后壳体部件相对的两边上的锁定臂74a末端的锁定钩74b已经从后面锁住了前壳体部件72的锁定肩部72a(图14)。因为底板连接器组件26对其的预锁定动作,这就防止了任何子板连接器组件的零件28向后移动。连接器在接合方向上进一步移动,导致适配器36的制动臂122末端的斜面122b接合后壳体部件74的锁定臂74a的倾斜末端,从而使该锁定臂74a移动脱离与固定肩部72a的接合。于是现在锁定臂74a的锁定钩74b能在前壳体部件72的锁定肩72a和锁定肩72b之间自由移动,在“Z”方向即接合方向使两个壳体部件能发生一定程度的移动。换而言之,在底板连接器组件彻底接合之前,两壳体部件在“Z”方向是无法移动的。
参见图23-28,其中详细介绍了光导纤维连接器模块的另一实施例。其中,图23是一个插入到上述适配器22中的光导纤维连接器模块125。每个模块125都包括一个在多线光缆126的一个光缆处终止的套盒136,光纤的末端126a在套盒136的接合面136a暴露出来。套盒136包括一对在接合面136a开口的校正孔136b。套盒136被手动操作的壳体148(图24)包裹,该壳体包括一真正包裹套盒的前部138a,和一具有一对横向隔开的臂138b的后部,臂138b可以由用户的手指捏合。套盒有外围凸缘136c。壳体138的前部138a在其相对两侧具有一对向前的锁定钩138c,在另相对两侧有一对有弹性的锁定臂138d。每个横向隔开的臂138b的外面都形成一个具有斜面的锁定凸块138d,这样用套盒内的锁定装置(图中未示)就能将套盒锁定在适配器内,手动操作臂在其外面有锯齿状突起,以辅助手动捏合。
图25表示套盒136能沿着箭头“B”的方向插入连接器模块125的壳体138。套盒在臂138b内的通道138f上移动,通过壳体前部138a的开放的后端138g。套盒在一个突出于壳体开放前端138h(图24)的位置锁定,由于向前的锁定钩138c和弹性锁定臂138b分别接合套盒136的凸缘136c的相对两侧边,套盒被锁在如图23显示的位置。
特别地,模板125的壳体138是中空的即具有开放前端138h(图24)和开放的后端138g(图25)。因此壳体具有一条穿过壳体中心的由前至后的轴144。当套盒136被组装到壳体中时,套盒的凸缘136c具有一条朝前的边146,其构成了和壳体向前锁定钩138c接合的向前锁定面。凸缘的后边148形成了向后接触面,其与壳体弹性锁定臂138d的前端接合。外围锁定面146与外围接触面148在轴144的横向伸展。
本发明认为,壳体138,特别是弹性锁定臂138d的前端,应设置一特殊的,朝前的接触面150,其与套盒向后接触面148接合。特别地,参考图23-25来看图26,可见向前的接触面150是中间凸出的圆弧形,其面对套盒136平直的即横向的接触面148。当套盒的前接合面136a与一互补的接合连接器的套盒前接合面接触时,壳体可能倾斜一定角度即发生歪斜,上述接触面150的设置就使套盒能相对壳体138而倾斜。
于图27和28中可见,套盒136能相对壳体138的做倾斜动作。在图27中,可见套盒沿着箭头“D”的方向发生倾斜即在凸面105附近转动。在图28中,套盒136相对壳体138沿着箭头“D”的方向发生相反方向的倾斜。图27和28清楚地描绘了当套盒的接触面148在弹性锁定臂138d的前端弧形接触面150前后转动时,套盒能前后倾斜摇晃。换言之,当连接器模块和一互补的匹配连接器模块接合时,套盒能相对壳体发生倾斜移动而弥补对齐不当的现象。
最后,虽然本发明只在此展示描述了在接合连接器组件10的底板连接器组件26上适配器22(图1和2)所用的光导纤维连接器模块25,125,该连接器模块能在图1和2所示组件之外得到广泛运用。
请注意本发明的构思和核心特征能以其它形式得以实现,这里的例子和实施例只是启示性的而非限制性的,本发明不限于这里给出的细节。
