用于混合光纤线缆的过渡连接器
相关申请
本申请主张2013年6月24日递交的美国临时专利申请No.61/838483和2013年6月24日递交的美国临时专利申请No.61/838466的优先权和权益,其每个的公开通过引用整体合并于此。
技术领域
本发明总体上涉及连接器,更特别地,涉及光纤和电力连接器。
背景技术
用于在无线基础设施中输送电力和数据的技术的最新发展使用混合线缆。当在本文中使用时,术语“混合光纤线缆”(hybrid optical fiber cable)意指既包括电力导体又包括一条或多条光纤索线或线缆的线缆。示范性的混合线缆是可从CommScope公司(伊利诺伊州Joliet市)获得的HFF线缆。与基于RF的系统不同,单条混合干线线缆(trunk cable)可用于对多个区段进行供电,从而消除了多条RF线缆的敷设。
为了使用单条混合干线线缆,在某个点该干线线缆必须过渡到混合跨接线缆(jumper cable)。通常,这些分布在机壳内,机壳将干线电力导体量规过渡到跨接电力导体量规并且将干线中的光纤连接到跨接线缆中的光纤。当前,过渡是通过在机壳内进行连接来实现的,这要求将机壳打开,将线缆馈送/匹配到机壳,并且进行电力和光纤连接,所有这些都在现场进行(例如,在靠近远程无线电单元(RRU)的小区站点顶上)。这种做法可能为安装者产生许多问题,包括时间、安全性、连接差错(例如松散的电力连接和/或不良的光纤清洁),并且连接器损坏的机会更多。
发明内容
作为第一方面,本发明的实施例涉及一种用于互连混合光纤线缆的连接器组装件。所述连接器组装件包括连接器模块和壳体,连接器模块居于壳体内。连接器模块包括:安装基底;安装在安装基底上的多个光纤适配器;以及安装在安装基底上的多个电力端口。
作为第二方面,本发明的实施例涉及一种线缆-连接器组装件。该线缆-连接器组装件包括连接器组装件、混合光纤线缆和多个混合光纤跨接线缆。连接器组装件包括:(i)连接器模块,包括:安装基底;安装在安装基底上的多个光纤适配器;以及安装在安装基底上的多个电力端口;以及(ii)壳体,连接器模块居于壳体内。混合光纤线缆插入到壳体中并且附接到光纤适配器和电力端口,多个混合光纤跨接线缆插入到壳体中并且附接到光纤适配器和电力端口。
作为第三方面,本发明的实施例涉及一种用于将圆形线缆与平坦线缆互连的连接器,包括:主体,具有相对的端面;在端面之间延伸的至少一个槽,该槽具有矩形截面;以及从槽分别向上和向下延伸的上凹陷和下凹陷,上凹陷和下凹陷是基本半圆柱状的并且彼此对准。

具体实施方式
参考附图来描述本发明,附图中示出了本发明的某些实施例。然而,本发明可以以许多不同的形式实现,而不应当被解释为限于本文图示和描述的实施例;更确切地说,提供这些实施例是为了使得本公开将会透彻且完整,并且将把本发明的范围充分地传达给本领域技术人员。还将会明白,本文公开的实施例可按任何方式和/或组合来结合以提供许多额外的实施例。
除非另有定义,否则本公开中使用的所有技术和科学术语具有与本发明所属领域的普通技术人员通常理解的相同的含义。以上描述中使用的术语是只为了描述特定实施例,而并不打算作为对本发明的限定。当在本公开中使用时,单数形式“一”和“该”旨在也包括复数形式,除非上下文另有明确指示。还将会理解,当称一元件(例如器件、电路等)“连接”或“耦合”到另一元件时,其可直接连接或耦合到该另一元件,或者可存在居间元件。相反,当称一元件“直接连接”或“直接耦合”到另一元件时,则不存在居间元件。
现在参考附图,图1示出了连接器组装件,其被宽泛地标示为10。连接器组装件10能够互连混合光纤线缆(即,既包括光纤又包括用于电力传输的导体的线缆),并且特别地可适用于将延伸长度的混合光纤线缆互连到较短长度的跨接线缆,和/或用于将单条混合光纤线缆与多条混合光纤线缆相连接。连接器组装件10包括连接器模块12和配接壳体14、16,连接器模块12居于这些配接壳体14、16内。这些组件将在下文中更详细地描述。
连接器模块12包括基板20,其上安装了八个分开的LC适配器22。连接光纤的LC适配器22具有常规构造,不需要在本文中详细描述。在一些实施例中,可以使用光纤耦合器或适配器的其他变体。通常由诸如聚氯乙烯(PVC)之类的聚合物材料形成的基板20包括中央孔隙24。
连接器模块12还包括基板30,其上安装了八个电力端口32。每个电力端口32包括两个螺孔34,其使得电力导体能够被连接在端口32内。基板30通常由镀锡的铜形成并且包括中央孔隙36。基板30经由四个间隔物38被安装成与基板20呈间隔开的关系。
在图示的实施例中采取中空截锥形状的壳体14、16被配置为将连接器模块12保持在其中。在其窄端,壳体14包括使其能够附接到混合光纤线缆(未示出)的装配件(fitting),混合光纤线缆包括多个光纤和电力导体。示范性的混合光纤线缆是可从CommScope公司(伊利诺伊州Joliet市)获得的
Figure BDA0000526560140000041
混合线缆。在其窄端,壳体16包括接收四个混合光纤跨接线缆或者说“直接尾部”(direct tail)(未示出)的装配件,其中每个跨接线缆/直接尾部对应于两个电力导体和两个光纤的一个“通道”。示范性的跨接线缆是也可从CommScope公司获得的
Figure BDA0000526560140000042
直接尾部。
壳体14、16通常由诸如PVC之类的聚合物材料形成。壳体14、16可通过任何方式的紧固方法附接到彼此;在图示的实施例中,它们是经由插入到其轮缘(rim)14a、16a中的螺钉来附接的。
在典型情况下,混合光纤线缆将在工厂用壳体14来端接,使得线缆中的光纤穿过壳体14的装配件并且插入到LC适配器22中,线缆中的电力导体穿过壳体14的装配件并且插入到电力端口32中。混合光纤跨接线缆将被插入到壳体16的装配件中的每个开口中,然后插入到LC适配器22和电力端口32中。通过壳体16插入的光纤穿过基板30的中央孔隙36。类似地,通过壳体14插入的电力导体穿过基板20的中央孔隙24。壳体14、16随后可经由螺钉等附接在一起。
连接器组装件10可为混合光纤线缆和跨接线缆提供被包封的连接点,其是相对紧凑且不突出的。在一些实施例中,组装的壳体14、16具有约4到6英寸之间的直径和约9到12英寸之间的长度。
也可使用不同配置的连接器模块。现在参考图2,示出了安装在壳体114中的连接器模块112,也示出了配接壳体116。连接器模块112仅包括单个基板作为安装基底,其上安装了六个LC适配器122和六个电力端口132。LC适配器122安装在基板120的周边附近,电力端口132安装在从LC适配器122起径向向内之处。注意,LC适配器122和电力端口132被安装成使得它们彼此交错,这为技术员将螺钉插入并拧紧在电力端口132的每个螺孔134中提供了空间。
现在参考图4,其中图示了连接器模块的另一实施例,其被宽泛地标示为412。连接器模块412与连接器模块112的相似之处在于其只具有一个基板420,并且其包括安装在基板420的周边附近的LC适配器422。然而,连接器模块412还包括六个电力端口440。每个电力端口440具有在一侧接收“平坦”电力导体并且在相反侧接收多达三个分开的圆形导体的能力。对电力端口440的更详细描述将在下文中阐述。
参考图6,电力端口440包括主体462(其可以是一体的或者由多个部件形成),主体462具有相对的顶表面和底表面464、466、圆形侧面468、470以及平坦端面472、474。槽478延伸于端面472、474之间。槽478一般有矩形截面;槽478通常具有约0.25到0.5之间的高/宽比。两个大体半圆的凹陷480、482分别从槽478的中央部分向上和向下延伸,并且在槽478的相反边缘基本彼此对准。两个孔隙476从顶表面464延伸到槽478。
在图4中可见,电力端口440可用于将平坦导体与圆形导体互连。如图所示,具有大体矩形的导体52(图4中示出了六个)的平坦线缆50可在一端(在此实例中是从上方)进入电力端口440之一的槽478并且将占据槽478的体积的除了凹陷480、482以外的部分。具有大体圆形导体62(图4中示出了六个)的圆形线缆60可在另一端(在此实例中是从下方)进入槽478并且将填充凹陷480、482的部分而不是槽478的其余部分。平坦和圆形导体50、60在电力端口460的主体462内彼此毗接。螺钉490可插入到孔隙476中以将导体50、60固定到电力端口440。
电力端口440可由几乎任何材料形成,但在一些实施例中是由诸如涂覆有锡的铝之类的导电材料形成的。导体50、60由导电材料形成;在一实施例中,平坦导体50由铝形成,圆形导体60由铜形成。
还应注意,在一些实施例中,螺钉490可配置为将导体50、60偏置为与电力端口440接触以改善电连接。这种螺钉(例如弹簧加载螺钉)将是本领域技术人员已知的。
类似的连接器模块212示于图3中,其包括安装在基板220上的六个LC适配器222和电力端口240。电力端口240(在图7中示出)与电力端口440类似,除了在槽278中存在六个大体上半圆柱的凹陷280a-c、282a-c。结果,电力端口240可用于将多达三个不同的圆形导体与单个平坦导体互连。
现在参考图5,其中图示了标示为312的连接器模块的另一实施例。连接器模块312包括单个基板320,其上安装了十二个LC适配器322。在LC适配器322的径向向内处,在基板320上安装了十二个电力端口332。然而,电力端口332配置为仅在一侧(即,图5的“后”侧)接收各个导体;在相反侧,公共接触板334安装到电力端口332并且与其电接触。由导电材料形成的公共接触板334包括配置为接收单个导体(未示出)的中央孔隙336。这个配置使得来自多个电力导体(在此实例中是十二个)的电力能被组合到从公共接触板334离开的单个导体中。
以上是对本发明的说明,而不应被解释为对其的限定。虽然已描述了本发明的示范性实施例,但本领域技术人员将容易明白,在不实质性地脱离本发明的新颖教导和优点的情况下,可对示范性实施例进行许多修改。因此,所有这种修改都旨在被包括在如权利要求所限定的本发明的范围之内。本发明由以下权利要求限定,权利要求的等同将被包括在其中。
