Description

减小电连接器中串扰的方法及装置
相关申请交叉参考
本申请要求以下申请的权利：于2004年4月1日提交的美国专利临时申请No.60/558,657号；以及于2004年3月12日提交的美国专利临时申请No.60/552,995号，这些专利申请通过引用全部结合于此。
技术领域
本发明涉及电连接器，尤其涉及应用补偿技术以减小由连接器组件的插头和插座的结合产生的净串扰的模块化通信连接器。
背景技术
包括局域网(LAN)和广域网(WAN)的计算机网络随着工作场所内的计算机和网络设备数量的增加而变得越来越普遍。这些计算机网络利用数据通信电缆和电连接器在连接到网络上的各种组件之间传输信息。电连接器通常被配置成包括插头，它可连接到安装在墙上或者集成在面板或其它远程通信设备中的插座。该插座通常包括外壳，它容纳用于接通插头的相应导体的间隔紧密的并行触点阵列。插座的触点通常安装在印刷电路板上。RJ45插头和插座连接器组件是一种公知的具有间隔紧密触点的标准连接器组件。
在过去的几年中，计算机网络技术的发展为通过网络传输数据的速率的相应提高提供了便利。传统的连接器用于传输低频数据信号而无明显的串扰问题。然而，当这种连接器用于传输高频数据信号时，连接器内产生的串扰显著增加。这种串扰主要是因为插座和/或插头中间隔紧密的并行导体之间的电容性或电感性耦合。
在电连接器设计中已对减少连接器内发生的串扰作了各种各样的改进。一个示例在共同受让给Panuit公司的美国专利No.6,305,950中公开。该类连接器结合包含电容器的多层印刷电路板使用特定导体结构来实现串扰效应的减小。然而，由于发生在此连接器的插头中极高频信号速率的高串扰电平，电容器可以达到的调谐效应依然难于实现。这样，要解决这些问题仍然需要连接器设计中的进一步改进，并提供经改进的串扰性能。
发明内容
根据本发明的一个实施例，通信连接器利用柔性印刷电路来提供串扰补偿。该柔性印刷电路与通信连接器的触点电接触。

具体实施方式
本发明涉及用于减少电连接器中串扰的方法和装置。本发明利用了授予Adriaenssens等人的美国专利No.5,997,358的减串扰原理，该专利通过引用全部结合于此。本申请进一步通过引用全部结合以下申请：2004年2月12日提交的题为“减小电连接器中串扰的方法和装置”(“Method andApparatus for Reducing Crosstalk in Electrical Connectors”)的共同受让美国临时专利申请No.60/544,050，以及2005年2月10日提交的题为“减小电连接器中串扰的方法和装置”(“Method and Apparatus for ReducingCrosstalk in Electrical Connectors”)的共同受让美国临时专利申请No.11/055,344。
现在参看图1，示出了电插座10的分解图。触点12适用于与插头触点(未在图1中示出)进行物理和电接触，并进一步与柔性印刷电路(FPC)14进行电接触。这些触点12被机械安装于触点滑橇16中，且触点-滑橇组件适于插入主插座外壳18中。
在图1示出的实施例中，FPC 14具有用于容纳绝缘位移连接器(IDC)22的刚性延伸部分20。根据本发明的一个实施例，该刚性延伸部分20是FPC的必要端部。该IDC 22伸出后部外壳24，并与导体26进行物理和电接触。在图1的实施例中，八个导体26被设置成四对。端盖28封装了IDC22和导体26间的连接。其它样式的终端也可在本发明中使用，如向下冲孔样式终端。
现在参看图2，接触组件的分解图示出了触点12和FPC 14之间在FPC14的插座触点30处的连接。FPC 14和触点12的机械和电连接位于插头/插座界面31的正下方。FPC 14的插座触点30较佳地通过焊接铆钉的电阻焊接焊接到在插头/插座界面反面的触点12上。插座触点12相对较短，且它们不沿长度方向传导信号电流。IDC 22从FPC 14的刚性延伸部分20伸出，进入FPC 14的IDC插座32。图3是图2触点组件的后视立体图，示出了FPC的插座触点30接触触点12，并且进一步示出了IDC 22从FPC 14的刚性延伸部分20延伸。
根据本发明的FPC可通过不同方法设置。例如，图4和5是示出电插座中FPC 14的两种配置的侧面剖视图。在图4中，FPC 14被放置成使FPC14的插座触点30向电插座10的后部弯曲。这是图1所示的配置。图5示出了另一种配置，其中在FPC 14中设置了前向弯曲34以使插座触点30向另一电插座36的前方弯曲。在图4和图5中，FPC 14的插座触点30与插座触点12在插头/插座界面31的正下方接触。
现在参看图6，示出了根据本发明一实施例的FPC 114的平面图。插座触点130包括用于电阻焊接到插座触点的焊接铆钉131。插座触点130从1到8编号以对应于八个导体(设置成四对)，并且相应地对IDC插座132编号。在FPC 114上设置导电轨迹138。FPC 114适用于图18-22所示的插座的“水平延伸”实施例。
FPC114使各插座触点与IDC电连接，并且它为标准插头的串扰耦合提供补偿。它利用美国专利No.5,997,358的示教来提供所述补偿。该FPC114被分成如图6所示的多个区域。
临界配对补偿用于如图6所示的导体对3、6至4、5。以下的区域描述相关于这些对，并且以下关于耦合的阐述相关于这些导体对之间的耦合。区域A、B、C、D、E和F在图6中用虚线框示出，且区域A-F中导电轨迹平面图分别在图6a-6f中示出。
区域A为从与插座触点112(如图18所示)的连接到近端串扰(NEXT)补偿区域的过渡区域。
区域B为NEXT补偿区域。
区域C为从NEXT补偿区域至NEXT串扰区域的过渡区域。该区域的设计目的是使其电感性和电容性耦合以及电路路径的长度与A区域的相等。
区域E为NEXT串扰区域。
区域F为连接NEXT串扰区域与IDC插座32的中性区域。
NEXT串扰区域的总串扰耦合的大小与标准插头的大约相等。
NEXT补偿区域的总补偿耦合的大小略小于标准插头串扰耦合的两倍加上区域A总耦合的两倍。
所有上述区域A-C、E和F都具有分布式耦合而无远程耦合。
在标准插头耦合的有效中心和NEXT补偿区域中心之间的相位角变化约等于在NEXT串扰区域中心和NEXT补偿区域之间的相位角变化。
因此，插座和标准插头的结合关于NEXT补偿区域的中心对称。
以上的结果是前向NEXT等于反向NEXT。
由于NEXT补偿区域通过FPC中的较短电路路径与插头/插座界面相连，它们之间的相位角变化被最小化且补偿随频率的变化被最小化。
NEXT补偿区域的总电感耦合约等于插座和标准插头的电路路径的平衡的总电感耦合。结果是很低的FEXT。
FPC的柔性使得它能与所有在安装插头时并不完全统一移动的插座触点相连。它也便于与IDC的不同方位或者与印刷电路板(PCB)相连。FPC的相比PCB较薄的介质层便于高密度的电感和电容耦合，而这又助长了相对较短的NEXT补偿区域。
NEXT补偿区域的长度较佳地约等于NEXT串扰区域长度。结果是趋于在单个FPC上一致的FPC轨迹宽度变化将NEXT补偿区域和NEXT串扰区域的电容耦合改变约相同的大小。这使得因轨迹宽度变化的补偿变化最小化。
区域D是补偿插座触点的补偿区域。它提供了靠近插头/插座界面连接的远程电容耦合。
如图6所示的对1，2&7，8的电路路径示出一种可实现这些对的结合之间的补偿的方法。这些其它对的所需补偿的实现比对3，6到4，5的容易得多。
图6h-6o分别示出与导体1-8相关联的导电轨迹，其中FPC 114上层的轨迹用实线示出而FPC 114下层的轨迹用虚线示出。通孔117是从FPC 114的上层到下层的导电路线。对3，6和4，5的导电轨迹的长度大致相等。
现在参看图7，沿图6g中线A-A的横截面图示出FPC 114的插座触点130的横截面。类似地，图8a是沿图6g中线B-B的横截面图。图8b是沿图6g中线C-C的横截面图。
图9是沿图6g中线D-D的横截面图。
图10a是沿图6g中线E-E的横截面图。
图10b是沿图6g中线F-F的横截面图。
图11是沿图6g中线G-G的横截面图。
图12是沿图6g中线H-H的横截面图。
图13是沿图6g中线I-I的横截面图。
与图7-13中导电轨迹相关联的标号1-8示出所引用的导电轨迹对应于FPC 114的插座触点130，并且又对应于与插座相连的相应导体。
图14-17分别是图6g的细节区域J、K、L和M的详图。图6g和图7-17中所示的尺寸以英寸为单位，并用于说明本发明一特定实施例。应该理解，可预期具有不同尺寸的实施例落在本发明的范围内。
现在参看图18，示出具有FPC114的水平延伸部分120的插座110的横截面图。与图1的实施例一样，触点112与FPC114进行电气和机械接触，并且插头-插座界面131置于位于触点112和FPC 114之间的该接触的正上方。IDC 122被插入FPC 114的水平延伸部分120的IDC插座中。例如向下冲孔终端的其它样式的终端，也可用于本发明。
图19是插座110的分解图。插座主外壳118适用于容纳具有安装其中的触点112的滑橇116。IDC块组件115附加于后部外壳124上，并且端盖128设置于插座110的后部。FPC114的延伸部分120水平地放置以容纳IDC122。图20是图19细节N的详图，示出了FPC114与触点112的电气和机械接触，并进一步示出IDC插座132适于与IDC 122相连。
图21、21a和22是示出外壳124、IDC块组件115、触点112以及具有水平方向刚性延伸部分120的FPC 114的立体图。在另一实施例中，如图21a所示，在IDC块组件115中，一对或多对IDC 122可设置有交叉干线123。
根据本发明的一个实施例，如图23所示，IDC 122设置有干线134，其中一些干线134具有交叉点136。图23是示出分别对应于插座的第一至第八导体的IDC 122a-h的立体图。第一至第八干线134a-h分别与第一至第八的IDC 122a-h相对应。第一和第二干线134a和134b在第一交叉点136a处彼此交叉，而第四和第五干线134d和134e在第二交叉点136b处彼此交叉。
图24是第一、第二、第七和第八IDC 122a、122b、122g和122h的俯视图，示出了第一和第二干线134a和134b中的第一交叉点136a。
图25是IDC 122a-h及其相关联干线134a-h的前视图，示出了第一和第二交叉点136a和136b。图26是IDC 122a-h的后视图，示出了图25的特征。
图27是图23实施例的侧视图，示出了IDC和相关联干线。示出了第一和第二干线134a和134b之间的第一交叉点136a。图28是图27细节O的视图，示出了第一交叉点136a。图29是图27细节P的视图，示出了第三和第六干线134c和134f。图30是图27截面Q-Q的横截面图，示出了具有其相关联干线134c-f的第三、第四、第五和第六IDC 122c-f，并进一步示出第四和第五干线134d和134e之间的第二交叉点136b。第一、第二、第七和第八干线134a、134b、134g和134h的横截面也在图30中示出。
图31是另一FPC 200的平面图，该FPC 200可与如图33-45所示的插座一起使用。插座触点230包括用于与插座触点电连接的通孔(镀膜通孔)231。该插座触点230对应于八个导体(设置成四对)。只有四个(导体3、4、5和6)在图31中示出。导电轨迹238设置在FPC 200上。FPC 200适用于图33-45所示插座的“垂直延伸部分”实施例。
FPC 200将各插座触点与IDC电连接，并且它为标准插头的串扰耦合提供补偿。它利用美国专利No.5,997,358的示教提供所述补偿。该FPC 200被分成如图31所示的多个区域。
临界配对补偿用于如图31所示的导体对3，6至4，5。以下的区域描述关于这些对，并且以下关于耦合的阐述相关于这些导体对之间的耦合。区域A、B、C、D和E在图31中示出。在下文中标识这些区域，但是功能已参照图6-17在上文中描述。
区域A为从与插座触点的连接到近端串扰(NEXT)补偿区域的过渡区域。
区域B为NEXT补偿区域。如所述，它包括可任选变化的电容250(参照图32在下文中描述)。
区域C为从NEXT补偿区域到NEXT串扰区域的过渡区域。本区域的设计目的是使其电感和电容耦合以及电路路径的长度与A区域的相等。
区域E为NEXT串扰区域。
图31中区域E以下的轨迹组成连接NEXT串扰区域(区域E)和IDC插座的中性区域。
图32是图31所示可变电容250的立体图。该可变电容250提供了随频率增加而有效减小的电容耦合。图32是该部分的示出电容板的上方立体图，其中为便于说明移去了衬底。一般而言，补偿区域的分布式耦合可随可变电容250远程耦合的电容改变大小而减小。可变电容耦合技术在2004年4月6日提交的序列号为60/559,846，题为“具有经改进串扰补偿的电连接器”(“Electrical Connector with Improved Crosstalk Compensation”)的美国专利申请中描述，该申请通过引用全部结合于此。
图33-45是本发明一说明性实施例的各个视图，其中交变长度触点包括用于连接到柔性印刷电路(FPC)的整体弹簧夹。图33-35是这种插座的部分侧面剖视图，图36和图39是整个插座的分解立体图。图37、38和40-42是插座组件的详细立体图。图43-45示出了插座触点(也称作插头界面触点)的细节。
插座300包括外壳302，它包括一体化前部梳(front comb)304和“夹心式”触点支架306，用于支撑和定位多个触点308。该前部梳304限制了触点308的上移。各触点308都具有对应的后部接触导槽310，在插头(未示出)插入插座300时触点308可移入该导槽310。FPC 312在一端与印刷电路板(PCB)314电气和机械连接，PCB 314进一步连接到与网络电缆(未示出)相连的IDC 316。FPC 312的第二端通过多个弹簧触点318与触点308相连。每个弹簧触点318较佳地为s形，以安全地支承FPC 312从而使触点308和FPC 312之间的良好电连接得到保持。该插座还包括用于将前滑橇(触点308分布在其周围)安装在外壳302中的底部固定板320。后滑橇324将外壳(和装于其中的组件)与线盖326机械连接，该线盖被设计成容纳放置有IDC 316中多条导线(未示出)的网络电缆。在所示特定线盖326中，应变消除夹328安全地将网络电缆夹持到合适位，从而减小网络电缆中各条导线上的应力。后滑槽324、线盖326和应变消除夹328的特定排列仅作为示例示出。也可使用许多其它设计，包括那些向下冲孔插座的设计。
参照图33-45描述的插座300的一个优点是使用具有交变长度的触点308。如图43-45所示，一半触点308a在长度上长于另一半308b。尽管各触点308上的弹簧触点318彼此对齐排列，但是围绕用于固定到触点支架306的前滑橇的低端部分从前滑橇322的一端到另一端实质上是交变的。在该较佳实施例中，中间两个触点308是仅有的两个长度相同的相邻触点308。相邻触点308a和308b之间的长度差异导致触点308a和308b相对彼此位于不同位置。这样减小了触点对之间的电容耦合，而电容耦合又减小了串扰。为容纳不同的触点308a和308b，前部梳304和前滑橇322被设计成用于触点的两种长度。
触点308设计的另一特征是与导线1和8(外部触点)相对应的触点长度较长。这有助于容纳8针插头(其中触点1和8与插头内相应触点电气连接)和6针插头(其中触点1和8被在大部分6针插头共用的固态塑料部分压下)。参见图34，示出了6针插头插入时的触点1或8。
弹簧触点308提供了一种不同于本文中其它实施例所述(即焊接等)的可选FPC连接机构。在制造(或安装)过程中，FPC 312可以插入到部分或全部弹簧触点318中。弹簧触点318提供了夹紧FPC的支撑力，以将其支承到位获得良好的电气连接。
所公开的发明提供了一种应用减串扰技术的电连接器。应该注意到以上描述和说明的本发明实施例和较佳实施例不是本发明可采取形式的穷尽列表；而相反用作本发明的目前所理解的示例性和说明性实施例。作为示例而非限制，图18-22中的插座110可被制造成具有FPC 114中的前向弯曲，类似于图5所示的前向弯曲34。
