技术领域
本发明涉及一种预端接盒,具体来说,涉及用来取出安装在接插板内的预端接盒的释放掣子。
背景技术
预端接铜线电缆或光纤电缆盒子可将电缆快速且可靠地安装到接插板。根据客户的技术规格书要求,在运输之前将预端接盒组装好。并在运输到客户之前,还需验证盒子的特性。因此,安装新的数据中心或改变现有数据中心的客户,可使用预端接盒来帮助最大程度地减小数据中心的停工时间,该停工时间通常与现场电缆终端、测试和安装有关。
现有的预端接盒包括位于盒子顶上的掣子或滑动臂。一旦将这样的盒子安装在接插板内,常常难于取出盒子,因为掣子不容易接近。当多个盒子安装到数据中心的接插板内时,脱开掣子和取出预端接盒都很困难,因为要求客户到达两排电缆之间来脱开掣子。因此,需要有一种具有释放机构的预端接盒,该机构容易进入并便于从接插板取出盒子。
发明内容
描述了一种将预端接盒安装到接插板中的释放掣子。该预端接盒包括允许从接插板中取出盒子的释放掣子,其中,接插板包括用来固定盒子的固定结构。释放掣子包括位于预端接盒侧壁上的悬臂梁。该悬臂梁具有允许悬臂梁相对于侧壁偏转的铰接点。释放的掣子还包括设置在悬臂梁远端的按压凸片和从悬臂梁表面中突出出来的掣子凸片。掣子凸片位于铰接点和按压凸片之间。当盒子安装在接插板内时,该掣子凸片能够与接插板的固定结构配合。
较佳地,预端接盒的每个侧壁具有释放掣子。此外,掣子凸片和接插板的固定结构可具有彼此互补的形状。可采用各种互补的形状,只要掣子凸片和接插板的固定结构彼此可配合即可。
在相对于盒子侧壁向内推压按压凸片时,掣子凸片最好能够向内偏转。掣子凸片在其向内偏转时可与接插板的固定结构脱开。
在优选实施例中,预端接盒包括抓持表面,该表面从预端接盒的侧壁延伸并与与按压凸片相邻定位。例如,抓持表面可以是位于预端接盒后面的延伸壁。在插入盒子或从接插板中取出盒子时,该抓持表面可向使用者提供让其抓持的附加表面。
还描述了一种用来接纳具有释放掣子的预端接盒的接插板。该接插板包括具有顶部和底部凸缘的框架。接插板包括多个顶部接插板凸片和多个底部接插板凸片,前者从顶部凸缘向下延伸,而后者从底部凸缘向上延伸。接插板还包括多个侧向导向器,侧向导向器具有适于接纳顶部接插板凸片的顶部狭槽和适于接纳底部接插板凸片的底部狭槽。侧向导向器包括一对导向掣子凸片。这两个导向掣子凸片从侧向导向器的后端向外延伸并彼此面对相对方向。导向掣子凸片可包括接插板的固定结构。较佳地,当盒子被接纳在相邻的侧向导向器之间时,接插板就固定住具有释放掣子的预端接盒。
在另一实施例中,接插板包括用来固定预端接盒的固定结构,安装到这种接插板内的预端接盒包括释放凸片。该释放的凸片具有连接到预端接盒表面的固定端和沿着盒子侧壁延伸的自由端。释放的凸片还包括位于凸片的固定端和自由端之间的铰接部分。当朝向盒子侧壁向内按压凸片时,自由端可与接插板的固定结构互相作用而从接插板中取出盒子。较佳地,释放凸片容纳在盒子侧壁和固定结构之间,由此使固定结构远离盒子侧壁偏转。
本技术领域内的技术人员适当地参照附图阅读以下的详细描述,将会明白本发明上述以及其它的方面和优点。此外,应该理解到,发明内容的概述仅是示例,而非限制如权利要求所要求保护的本发明的范围。

具体实施方式
图1和2示出带有安装在接插板内多个侧向导向器50的典型的接插板20。接插板20接纳多个定位在相邻侧向导向器50之间的预端接盒80。预端接盒80直地插入接插板20内,直到预端接盒80卡配在相邻侧向导向器50之间的接插板内为止。
图3示出带有本发明侧向导向器50的接插板20的分解立体图。接插板20包括框架22,框架22具有顶部凸缘24、底部凸缘26和多个开口28。接插板20的各端包括安装板32,安装板32具有孔34,用来将接插板固定到网络机架(未示出)上。
接插板20包括多个接插板凸片40、41。如图3所示,接插板凸片40从顶部凸缘24向下延伸,接插板凸片41从底部凸缘26向上延伸。接插板凸片40可比接插板凸片41短。接插板凸片40、41位于接插板20中的各个开口28的端部附近。接插板20的顶部凸缘24还包括多个定向槽口42。定向槽口42定位在从接插板框架22的顶部凸缘24延伸出来的接插板凸片40的后面。
接插板的顶部凸缘24和底部凸缘26还分别包括多个支承突缘25、27。支承突缘25和27与各个预端接盒对中,当预端接盒安装在接插板内时,各支承突缘帮助引导各个预端接盒。
图3还示出侧向导向器50在安装到接插板20之前的一个本发明侧向导向器50,而图4和5示出安装在接插板20内的侧向导向器50。侧向导向器50可包括用来将预端接盒固定在接插板20内的固定结构。除了支承凸缘25和27之外,侧向导向器50引导预端接盒80,使预端接盒80合适地定位在接插板20内。侧向导向器50还确保预端接盒80固定在接插板20。
每个侧向导向器50的顶部52和底部54分别包括开口或狭槽56、57。如下文中将讨论的,当侧向导向器50安装在接插板20内时,狭槽56接纳一个接插板凸片40,而狭槽57接纳一个接插板凸片41。侧向导向器50还包括定位在侧向导向器50的顶部52和底部54附近的侧向导向器50内的导向凸片60。该导向凸片60设计成:当侧向导向器50安装在接插板20内时,导向凸片60与接插板凸片40、41配合。
侧向导向器50的顶部52还包括定向凸片62。该定向凸片62与接插板20内地定向槽口42对齐,以确保侧向导向器50合适地安装在接插板20内。每个侧向导向器50的中心包括一对柔性的导向掣子凸片64,它们从侧向导向器50的背部向外延伸。导向掣子凸片64包括唇形物66,当预端接盒安装到接插板20内时,该唇形物66与预端接盒80的侧壁82(见图2和图6-9)配合。或者,导向掣子凸片64包括唇形物,当预端接盒安装到接插板20内时,该唇形物与预端接盒115的掣子凸片128(见图12-17)配合,或与预端接的、高密度的多光纤推进(MPO)电缆组件150的掣子片128(见图18-19)配合。
侧向导向器50滑入接插板20内,使接插板凸片40、41分别定位在狭槽56、57内。接插板凸片40和接插板凸片41分别用键仅配装到狭槽56和57内,以确保侧向导向器50合适地安装在接插板内。一旦侧向导向器50滑入接插板20内,则导向凸片60就与接插板凸片40、41配合。固定住定向片62使其与定向槽口42对齐,这也确保侧向导向器50合适地安装在接插板20内。如图4所示,侧向导向器50安装在接插板20内,使得侧向导向器50与接插板框架22齐平,而定向凸片62定位在接插板20的定向槽口42内。
如图1、2和6-9所示,根据本发明实施例的预端接盒80包括一对释放凸片84。释放凸片84从预端接盒80的后角延伸,并沿着预端接盒80的侧壁82定位。释放凸片84包括带有自由端88的铰接部分86。自由端88朝向盒子侧壁82向下延伸。释放凸片84类似于美国专利No.5,993,236号中披露的模块化插头的掣子臂,该专利受让于本发明的受让人,本文援引其以供参考。
图2、6和7示出安装在接插板20内的侧向导向器50中的预端接盒80。导向掣子片64的唇形物66与预端接盒80的侧壁82配合,以将预端接盒80固定在接插板20内。预端接盒80的释放凸片84与导向掣子凸片64之一相邻定位。
如图8和9所示,为了从接插板20中取出预端接盒80,按压释放凸片84,使导向掣子凸片64开始与盒子侧壁82脱离。释放凸片84容纳在盒子侧壁82和导向掣子凸片64之间,由此移动导向掣子凸片64。当完全按压释放凸片84时,导向掣子凸片64清空盒子侧壁82,能使预端接盒80从接插板20取出。
本发明该实施例的预端接盒80和释放机构还可用于倾斜的接插板或高密度的接插板。例如,图10示出带有用来接纳预端接盒80的本发明侧向导向器50的倾斜的接插板120。图11示出带有用来接纳预端接盒80的本发明侧向导向器50的高密度的接插板220。
预端接盒80的释放机构能使客户不用任何工具就可快速地从接插板中取出预端接盒,对于任何要求的移动、添加或改变只需用一个手就可解决。
图12-17示出本发明预端接盒另一实施例的预端接盒115。本发明该附加实施例类似于参照图6-9所述的预端接盒80。例如,该附加实施例可安装在与上述安装预端接盒80的同样的接插板20内。如图17所示,接插板20可接纳多个预端接盒115,以使预端接盒115可定位在侧向导向器50之间。预端接盒115可直地插入接插板20内,直到盒子115卡配在相邻侧向导向器50之间的接插板内。然而,与预端接盒80不同,图12-17所示实施例具有的释放机构不同于预端接盒80的释放机构。下面将详细描述预端接盒115的释放机构。
图12示出预端接盒115的局部后视立体图。预端接盒115可具有盒子底部121和盒子盖子123。盒子底部121包括释放掣子122。或者,盒子盖子123可包括释放掣子。图13-14是预端接盒115的盒子底部121的立体图,它们更详细地示出释放掣子122。
预端接盒115包括一对释放掣子122。尽管图12-14示出了预端接盒或盒子底部一侧的局部图,但应该理解到,另一侧具有基本上类似的释放掣子的设计。释放掣子122位于预端接盒底部121的侧壁125。释放掣子122是悬臂梁124,该悬臂梁具有铰接点、掣子凸片128和按压凸片130。盒子底部121较佳地包括从盒子底部121的边缘延伸的延伸壁134。延伸壁134位于盒子底部121的后部而在释放掣子122上方。
可操作预端接盒底部侧壁125内的狭槽136来形成该悬臂梁124。如图所示,该狭槽136朝向预端接盒底部的底定位。狭槽可从铰接点126延伸到延伸壁134。
释放掣子122还包括掣子凸片128。该掣子凸片128可以是从预端接盒底部121的悬臂梁124中延伸出来的突出物。该释放掣子还包括按压凸片130。因为掣子凸片128位于悬臂梁铰接点126和压迫凸片130之间,所以当向内按压该按压凸片130时,掣子凸片128将向内移动。此外,盒子底部121的侧壁125可包括延伸壁134。该延伸壁位于预端接盒底部121的后部,最好位于按压凸片130上方。该延伸壁最好用作抓持表面,当客户为了安装或取出预端接盒而按压按压凸片130时,该延伸壁可为客户有利地提供附加的抓持。
此外,在优选实施例中,如图14所示,预端接盒底部121包括盒子底部121内部142的肋140上的槽口138。该槽口138可位于内部肋140上,以对释放掣子122提供间隙。此外,槽口138可用作释放掣子122的主动止挡件,以防止释放掣子122的悬臂梁124过度偏转。过度偏转可在悬臂梁的铰接点126处造成过度的应力。槽口138较佳地限制铰接点126处的应力,这样可提高释放掣子的结构稳定性和强度。
诸如预端接盒115那样的预端接盒可容易地安装在所述接插板内和从接插板中取出。图15和16示出安装在接插板20的侧向导向器50内的预端接盒115。接插板20的导向掣子凸片64的唇形物66与释放掣子122的掣子凸片128配合,以将预端接盒115固定在接插板20内。为了使彼此配合,导向掣子凸片64和掣子凸片128具有互补的形状。应该理解到,尽管图15和16示出了导向掣子凸片和掣子凸片的互补形状的一个实例,但同样也可能有导向掣子凸片和掣子凸片的其它形状,只要导向掣子凸片和掣子凸片彼此配合即可。当预端接盒115完全插入接插板20时,掣子凸片128可卡配和锁定在导向掣子凸片64后面。当掣子凸片128与导向掣子凸片64配合时,接插板20牢固地将预端接盒115锁定并固定就位。
此外,接插板20和预端接盒115的对应掣子互相协作,在有机械载荷施加到预端接盒的情况下,两者的协作就可将预端接盒115在接插板内牢固地固定就位。释放掣子122最好是自激励的掣子,这样,当盒子经受向后或侧向载荷时,该掣子增强与接插板固定结构的配合。例如,在向后和/或侧向载荷施加到预端接盒115的情况下,接插板20的导向掣子凸片64和预端接盒115的掣子凸片128就增强了这种配合。具体来说,施加在预端接盒115上的向后或侧向载荷将使导向掣子凸片64和掣子凸片128彼此配合,甚至比没有施加载荷的情形还要紧密。例如,如果预端接盒的电缆意外地被曳拉、猛拉或扭转,则导向掣子凸片64和掣子凸片128彼此配合将增强彼此的配合,预端接盒115将保持固定在接插板20内。
如图16所示,为了从接插板20中取出预端接盒115,可按压按压凸片130,使导向掣子凸片64开始与预端接盒掣子凸片128脱离。为了从接插板中取出预端接盒115,客户可通过抓持延伸壁134和按压凸片130来抓持预端接盒115,并向内按压按压片,将预端接盒115拉出接插板20之外。当按压或向内推压按压凸片130时,如图16中虚线所示,掣子凸片128也向内偏转。按压凸片和掣子凸片128的向内移动使掣子凸片与接插板20的导向掣子凸片64的唇形物66脱离。掣子凸片128可清除接插板20的导向掣子凸片64的唇形物66。当掣子凸片128清除导向掣子凸片64的唇形物66时,可容易地从接插板20取出预端接盒115。
如同预端接盒80一样,本发明该实施例的预端接盒115和释放掣子也可用于倾斜的接插板或高密度的接插板。例如,图10示出带有本发明侧向导向器50的倾斜的接插板120,其可接纳诸如预端接盒80或预端接盒115那样的预端接盒。图11示出带有安装成接纳预端接盒的本发明侧向导向器50的高密度的接插板220。
本发明该实施例的优点在于,在有意地从接插板中取出盒子过程中,预端接盒115需要非常小的按压力来释放掣子和脱开盒子。一旦施加了压力,悬臂梁就可容易地偏转。此外,如同具有上述掣子84的预端接盒80一样,预端接盒115的释放掣子122能使客户快速地从接插板取出预端接盒,无需任何工具而对于任何要求的移动、添加或改变只需用一只手即可。
此外,预端接盒115的延伸壁特征,有利地为客户在从接插板中取出预端接盒时能够抓持盒子提供了方便的结构。该种抓持能力允许客户无需为了帮助从接插板中取出盒子而抓持预端接盒的电缆。例如,在预端接盒115是光纤预端接盒的情况下,不需要客户抓持光纤电缆来帮助从接插板取出预端接盒。如果客户抓持光纤电缆来帮助取出盒子,则可能发生光纤连接器终端或光纤的损坏。所述释放掣子和延伸壁允许使用者容易地从接插板中取出预端接盒而无需抓住电缆来帮助取出盒子。
图18-19示出本发明另一实施例。具体来说,图18-19显示根据本发明实施例的预端接、高密度的多纤维推进(MPO)电缆组件150。如图18-19所示,盒子组件150包括与上述预端接盒115相同的释放掣子122。因此,盒子组件150可安装到与上述可安装预端接盒80和预端接盒115的同样的接插板20内。
图19示出预端接、高密度的多纤维推进(MPO)电缆组件150的分解图。盒子组件150包括底部152和盖子154。底部和盖子可卡配在一起。盒子组件150还包括可卡配到底部152内的MPO型适配器156。该底部可包括多个矩形孔158来固定MPO型适配器156。矩形孔158可接纳MPO型的适配器156。尽管图中显示六个矩形孔158,但如果只需要少量MPO型的适配器156,则可设置较少的矩形孔158。
多光纤电缆160可终止于MPO光纤连接器162。当连接器和适配器安装在底部152内时,光纤连接器162可与MPO型的适配器156匹配。电缆160可用应变释放配件164和固定螺母166附连到底部152。电缆160的强度构件可较佳地用螺钉168和螺母170附连到底部。底部可含有凸台172,该凸台提供用于螺钉168的孔。此外,角撑板174可添加到凸台172上来增加强度。将强度构件附加到底部上,可在现场电缆安装期间较佳地提供所需的附加拉伸强度。
盒子组件150还可在盒子后部包括倾斜的外形180。可操作倾斜的外形180来对盒子插入普通的接插板和从其中取出提供间隙。从多个原因来讲这一点是有利的。例如,顾客可到达盒子之间后取出个别的盒子,无需干扰其它的盒子。此外,倾斜的外形180可对客户提供额外的抓持,以便在将盒子150插入接插板20或从其中取出盒子150时可抓持盒子。倾斜的外形180可允许客户避免为了帮助从接插板中取出盒子而抓住电缆160。此外,因为盒子组件150具有倾斜的外形,所以,包括延伸壁134来提供附加的抓持并不是关键的。然而,应该理解到,盒子组件150可包括延伸壁134来提供附加的抓持。
如上所讨论的,盒子组件150可安装到诸如接插板20那样的接插板内。具有释放掣子122的盒子组件150也可用于倾斜的接插板或高密度的接插板。例如,在优选实施例中,盒子组件150可安装在如图10所示的倾斜的接插板120内。由于盒子组件150的倾斜外形180,盒子可插入到普通倾斜的倾斜接插板120内,而不会受到安装好的邻近盒子的阻碍。同样地,盒子可从移入的倾斜接插板120中取出,而不会受到安装在接插板内的相邻盒子的阻碍。
此外,尽管已经显示和描述了本发明的特别优选的实施例,但本技术领域内的技术人员显然明白,还可作出许多变化和修改而不脱离本发明的范围。提供以上描述和附图中所阐述的内容仅是举例而已并无限制意义。
应该理解到,所示的实施例只是实例而已,不应看作限制本发明的范围。除非另有所述,权利要求书都不应看作局限于所描述的次序或构件。因此,本发明要求保护所有落入附后权利要求书和其等价物所述的范围和精神内的所有实施例。
