技术领域
本发明总的涉及电连接器,更具体地说,涉及一种具有固定至柔性印刷电路的压接触点的通信插座。
背景技术
在通信行业中,随着数据传输速率的稳步提高,由于电容和电感联接器而在插座和/或插头内紧密间隔的平行导线之间形成的串扰越来越成问题。已经设计了具有改进的串扰性能的模块化连接器,以满足日益提高的苛刻标准。许多这些改进的连接器包括在美国专利第5,997,358号中披露的概念,在此以参见的方式引入该专利的全文。具体地说,目前的连接器已经引入了预定量的串扰补偿,以抵消令人不快的近端串扰(NEXT)。使用两个或多个补偿段来考虑到相移,该相移源自由补偿区域和插头/插座接口的距离而产生的传播延迟。结果,令人不快的串扰的量级和相位被该补偿所抵消,从而合计起来具有相等的量级但相反的相位。
目前包括超过500MHz的传输速率已经超出了′358专利中披露的技术能力。因此,需要改进的补偿技术。

具体实施方式
图1是根据本发明的一个实施例的通信插座10的立体图。插座10包括主插座罩壳12和例如通过罩壳夹16附连至主插座罩壳12的后插座罩壳14。后插座罩壳14可以设有用于绝缘层剥离触点(IDC)18(如图2所示)的通道。导线盖20形成用于双绞线通信缆的接口。或者,可将向下冲孔块结合在通信插座10中。主插座罩壳12包括用于接纳通信插头的容座22,容座22内的插头接口触点24与插头的触点相接触。
插头接口触点24保持在触点承载组件26内,如图2所示。触点承载组件26包括适于固定印刷电路板(PCB)32的触点橇28和垂直支承件30。印刷电路板32包括柔性部分34,该柔性部分34具有插座触点36以附连至插头接口触点24。PCB32还包括刚性部分38,IDC18电气地和机械地(例如通过柔性销)附连至该刚性部分38。PCB32提供插头接口触点24与IDC18之间的电连接,还提供用于行进通过通信插座10的通信信号的串扰补偿。
PCB32的柔性部分34的平面图示于图3中。插座触点36a-36h对应于第一至第八插头接口触点24。第一至第八插座触点36a-36h中的每一个具有在PCB32上的对应导电迹线1-8。在图3的平面图中,沿着柔性部分34的顶部的导电迹线显示成实线,而沿着柔性部分34的底部的导电迹线显示成虚线。
PCB32的补偿电路分成诸区域,这与2005年3月11日提交的、待审查的美国专利申请第11/078,816号中所示的分区类似。具体地说,本发明的补偿电路如′816申请所述分成六个区域A-F,且还包括第七区域G。
区域A是从插座触点36a-36h到近端串扰(NEXT)补偿区域的过渡区域。
区域B是NEXT补偿区域。
区域C是从NEXT补偿区域到NEXT串扰区域的过渡区域。
区域D是补偿操作触点的补偿区域。
区域E是NEXT串扰区域。
区域F是中性区域,该区域将NEXT串扰区域连接至IDC插口40,如图8所示。
区域G是可变的补偿区域,该区域随着频率增大而减小NEXT补偿。
图3以英寸为单位示出了区域A、B、C和E的大致长度。
在区域B、D和F内,一些导电迹线具有电容板,从而允许导线之间的电容补偿。这些电容联接器在图3中标示为“Cx,y”,这里x是沿着柔性部分34的顶部的对应导电迹线,而y是沿着柔性部分34的底部的对应导电迹线,它们在该联接器处电容联接。例如,图3所示的C2,5是在顶部的第二导电迹线和底部的第五导电迹线之间的电容联接器。 除了第一、第七和第八导电迹线之外的所有导电迹线通过导电通路46a-g在柔性部分34的顶部和底部之间转移,如图3-5所示。
本发明PCB32的柔性部分34结合了附加的特征,以帮助在通信插座10中适于使用六或八触点的插头。如图3所示且如下文所更详细描述的,对于第一插座触点36a和第八插座触点36h提供细长的连接延伸部42a和42h。此外,第一狭缝44a和第二狭缝44b切割入柔性部分34,以允许细长的连接延伸部42a和42h比第二至第七插座触点36b-36g的连接延伸部更加弯曲。
图6和7分别示出了沿着图3的线6-6和7-7的柔性部分34的剖视图。图6示出了通过触点通路48的剖面,第一插座触点36a在该触点通路48处连接至第一插头接口触点24。剖面示出了例如由KAPTON聚酰亚胺膜制成的柔性内芯50。在插座触点36的区域中沿着顶层和底层设置触垫52。通路48是导电的,且可以是镀铜的。图7示出了通过分别与图3所示的第一和第二导线相关联的连接延伸部42a和42b的剖面。剖面中的每一个都示出了柔性内芯。与第一导线相关联的迹线1示于图7中的底层上,而与第二导线相关联的迹线2示于顶层上。
图8是印刷电路板32的平面图,示出了柔性部分34和刚性部分38。刚性部分包括IDC插口40和区域F的导电迹线。
现在转到图9和10,两个视图示出了PCB的柔性部分34适于六个和八个导线的插头的适用性。如同在美国专利申请第11/078,816号中所描述的且还如图10所示,插头-插座接口设置于插头接口触点24和柔性电路板(或电路板的柔性部分)之间的触点的紧邻上方。当没有安装插头(如图11和12所示)或安装了标准的八触点插头时,这些触点位置几乎位于一直线上。然而,当安装了六触点的插头(如图13和14所示)时,触点1和8比触点2-7更加偏斜。
如图9所示,区域A的将迹线1和8连接至插座触点1和8的连接延伸部42a和42h已经伸长,而如图10所示,它已经结合了“S”形弯曲部以在六触点插头安装在插座中时有利于触点1和8形成与触点2-7的偏斜相比的附加偏斜。
如图13和14所示,与第八迹线相关联的较长连接延伸部42h允许在六触点插头***容座22时使插头接口触点24h(与第八导线相关)有较大的偏斜。
在邻近和处于插头-插座接口54的相对侧处,PCB32的柔性部分34与插头接口触点24的机械和电气连接的较佳设计示于图15-17中。这种连接是通过如图15所示将插头接口触点24的自由端56弯回其自身上、并且通过在邻近PCB32的柔性部分34的连接延伸部42处将每个触点的两个部分58和60点焊在一起来作出的。连接延伸部42夹在每个触点的两个部分58和60之间。图16和17所示的点焊步骤可以用电焊条62a和62b来实施。
所述的波状焊接触点提供摩擦力,以允许插头接口触点夹住连接延伸部42。如图18所示,插头接口触点24可以在它们接触触点通路48之处的区域中、在插头-插座接口54下方设有夹紧结构64。通路48上的插头接口触点24的夹紧可以通过诸如在触点24上冲制、切削细齿、或磨损触点、或辊轧成齿之类的多种方法来得以增强。
图19和20示出了将柔性印刷电路板或电路板的柔性部分34连接至插座触点的另一方式。在此实施例中,插座触点是设有第一和第二弯部68和70的夹式触点66。电路板的柔性部分34的的连接延伸部42通过夹式触点66的第二弯部70和夹式触点的直线部分72之间的摩擦力而固定在插头-插座接口下方。
尽管以上的讨论指出了将PCB的柔性部分连接至插头接口触点,但是应该理解,对于不含刚性部分的柔性印刷电路板(FPC)也可以用这种连接方法。
尽管已经显示和描述了本发明尤其较佳的实施例,但是对于熟悉本领域的技术人员显而易见的是,可以在不脱离本发明的说明的前提下作出修改和变型。在前面的描述和附图中所阐述的内容仅仅是以示例而并非作为限制的方式来提供的。
