Description

用于建立大功率数据导线连接的接线盒和插接口
本发明涉及一种插接口和一种接线盒,用以建立包括这样的插接口的大功率数据导线连接,如权利要求1或9所述。
为了建立从一发送台到一终端设备(信道)或在各具有高数据传输容量的相应的接线盒(接线)之间的数据导线连接,信道或接线的全部的部件,特别是数据电缆和接线盒关于其传输特性必须满足某些最低的要求。各部件按其传输特性分为不同的类别,其中目前类别5、5e和6是特别有意义的。已计划使对于所涉及的类别的部件的技术要求标准化。按照这样的标准化建议,类别5、5e和6电缆的电缆必须在100MHz时抑制包括32.3、35.3或44.3dB(分贝)的近端串话(近端串话或紧接的(NEXT))。对于类别5、5e和6的接线盒,值40、43或54dB对100MHz时的紧接损失(NEXT-Verluste)适用。目前对于电缆可以较好地满足类别5、5e和6的要求。但对于接线盒特别是类别6的接线盒却没有满意的解决方案。
接线盒通常包括至少一个插接口,例如RJ 45插接口,其具有一个用于数据电缆的插头的容纳元件和许多钩形弯曲的长形的接触元件,后者沿容纳元件的大部分长度延伸并且在应用情况下与数据电缆的各个导线或对应的接触元件在插头上进入接触。插接口固定在一基极印刷电路板(Basisleiterplatte)上,后者包括对用于另一通常固定的数据电缆的端子板的电缆连接。插接口的各钩形接触元件的各一端通过容纳元件并直接与基极印刷电路板或其上的电缆连接焊接。在已知的结构中,各导电的部件相互在空间上直接邻近并相互干扰而没有屏蔽。RJ 45插接口具有8个并列的接触元件用于相应的数据电缆的4对导线。为了接触元件1/2、4/5和7/8配置各一对导线,为一对导线分配给接触元件3和6。由于这样的空间设置,在一对3/6和4/5之间的干扰是特别大的。
为了减少干扰,已知,基极印刷电路板配备有一补偿电路,其将各个导线或各对导线相互例如电容性地去耦。具有这样的补偿电路的接线盒一般满足类别5或5e的要求。但为了转入类别6,在100MHz时改进11dB是必需的,对此所提出的设计至今没有实现。
因此本发明的目的在于,提出一种具有改进的传输特性的插接口和接线盒。插接口应该优选具有已应用的插接口的几何形状,特别是按照RJ 45,以便与通行的标准插头相容。
该目的通过具有权利要求1的特征的插接口以及具有权利要求9的特征的接线盒来达到。本发明的有利的进一步设计由各从属权利要求、说明书描述和附图得出。
本发明基于这样的出乎意料的认识,即,即使是小于所涉及的信号的波长的1/10的结构也对相互的干扰具有影响。基极印刷电路板的补偿电路向插接口的接触元件的空间上直接邻近的偏移致使补偿得到明显改进,特别是对于紧接的(NEXT)值。通过接触元件或信号通路从插头的接触元件直到补偿电路或到另一电缆的接头的长度的缩短加强这样的效果。信号依靠插接口便已得到补偿,并且不必或者不费事地在基极印刷电路上校正。
按照本发明,插接口的各接触元件固定在一补偿印刷电路板上,其包括一补偿电路,用以减少各导线之间的干扰影响,特别是串话影响,并且它设置在插头用的容纳元件内。插接口的接触元件做得很短,因为其只从插头的接触元件延伸到补偿印刷电路板并且不必象在现有技术中那样通过插接口或容纳元件。降低了各信号通路之间的相互干扰强度,特别是相互串话。最后,可以在补偿印刷电路板上简化补偿电路,例如采用较小容量的补偿器。
补偿印刷电路板可以结合于任何的插接口中,其容纳元件以本身已知的形式匹配于插头。借此避免在转变为类别6的部件时的相容性问题。优选采用符合RJ 45形式的容纳元件或插接口。补偿印刷电路板例如沿容纳元件的底面延伸或构成该底面。补偿印刷电路板是可取出的。优选设有安装元件,用以固定在基极印刷电路板上,特别优选使其可固定在相对于后者的不同的位置。
接线盒除了包括至少一个本发明的插接口外,还包括一基极印刷电路板和一端子板。其可以设有其他的元件,例如用于构成一特别是屏蔽的壳体。该壳体可以按已知的方式构成,例如按照EP-A 0928052。
本发明的各实施例示于附图中并且描述如下。其中:
图1、2示意示出本发明的插接口的前倾或后倾的视图;
图3、4示意示出本发明的接线盒的剖面图,其包括一个位于两不同安装位置的插接口;
图5示意示出两个相互连接的插接口;
图6a、6b示意示出补偿电路的实例。
图1和2示出本发明的插接口的两个立体视图,其包括一容纳元件1,后者构成一如在传统的RJ 45插接口中那样成形的插头用的空隙11。图3和4示出该插接口在一基极印刷电路板9上的两个不同的安装位置。
容纳元件1具有一基本上长方体形的基本形状,包括一底面和顶面1a或1b以及两平行的侧面1c、1d。其后面的区域1e在此构成为倾斜的或棱柱形的,以便连接元件可以以不同的安装位置安装到基极印刷电路板上(图3和4)。
本发明的补偿印刷电路板2设置在容纳元件1内,这里设置在底面1a的区域内。补偿印刷电路板2在必要时可以替代底面1a。各钩形弯曲的弹性接触元件3位于补偿印刷电路板2上,其接触面3a伸入空隙11中并且倾斜向下或向远离插头用的插入口的方向定位。如图3中所示,接触元件3的长度L只为一小部分,在这里约为插接口的沿插入方向E测定的长度的1/4,而在现有技术中接触元件一般沿插接口的全长延伸。在补偿印刷电路板2上还具有一补偿电路13,其在这里只作示意。补偿电路13的实例示于图6a、6b中。补偿电路13连接接触元件3与其中销形的接头7,借其在图3、4中所示的应用情况中建立与基极印刷电路板9的电接触。补偿印刷电路板2支承于容纳元件1的两侧面的凹槽10中并且借助于锁定连接6固定,后者包括一在补偿印刷电路板2中的孔隙和一在底面中的锁定凸起。按这种方式确保插接口的简单的组装。容纳元件优选是单件的,特别是一注塑成型件。插接口可以包括一附加的金属的屏蔽,其例如围绕着容纳元件。
容纳元件1具有锁定凸起或基脚形式的安装元件5,其用于在基极印刷电路板9的相应的孔隙14中的固定。各安装元件5相对于底面1a以不同的方位设置,从而可以实现插接口的不同的安装位置。按这种方式,插头的插入方向E可以适应于安装方面的要求,例如平行于(图3)底面1a或与其成一角度α(图4),其一般平行于容纳接线盒的壁定位。
一端子板8例如也以接线板的形式与基极印刷电路板9相连接,其在应用情况下用于一通常固定敷设的数据电缆的各导线的永久连接。通过未示出的在基极印刷电路板9上的电缆连接和接头7,在插接口内建立与相应的接触元件3的电接触。基极印刷电路板9还可以具有另一补偿电路,用以抵消在插接口以外出现的串话。
容纳元件1在侧面具有相互配合的连接元件4、4′,其中它们为一内凹的导轨的形式或一燕尾榫成型,用于多个插接口的相互连接。这样的插接口设置的实例示于图5中。
对于补偿印刷电路板和基极印刷电路板,可以采用标准元件,例如双面的FR 4印刷电路板。
图6a、6b示出补偿电路的实例。补偿印刷电路板2的上面和下面设有相应的电子部件,例如导线元件15和补偿器16。当前在各导线元件之间设有各一个去耦补偿器16,其为各对引线1/3、3/5、4/6和6/8而配置。这些电容的典型值例如对于各对1/3和6/8为0.81pF而对于各对3/5和4/6为0.92pF(分别在250MHz下)。在至今已知的基极印刷电路板上的补偿电路中则采用明显更高的电容和/或更复杂的电路,例如一去耦电路在规定的各对引线之间具有下列电容:对6/4:2.1pF;对5/3:2.14pF;对6/8:1.84pF;对3/8:1.4pF;对1/3:0.58pF。
补偿印刷电路板2在其尺寸上匹配于插接口的大小,在此其约为17mm长和12mm宽。
