本发明涉及通信设备技术领域，尤其涉及一种背板组件以及通信设备。
随着电信和互联网业务的迅猛发展，业务流量井喷式增长，市场对通信设备的交叉容量也提出了更高的需求，现在单业务板的交叉容量已经向400G甚至1T迈进，单线速率达28G甚至更高，系统走线也更加困难。目前的通信设备，最常用的是单面交叉系统。
为了增加单面交叉系统的交叉容量，通常采用的三种方法为：一是增加交叉板和业务板数量，但整个单面交叉系统的尺寸有一定的标准，目前单面的单板数量已达到极限；二是增加单线速率，这受限于PCB(Printed Circuit Board，印制电路板)的加工工艺和交换芯片的发展；三是增加每个业务板下背板的Serdes(SERializer-DESerializer，串行器-解串器)数量，PCB的厚度也会相应的加厚。对于目前的单面交叉系统，存在的缺点为：受限于PCB厂家的加工能力，背板PCB的厚度已不能再增加，交叉容量小，难以满足目前的交叉容量需求。

本发明提供一种背板组件。
参照图1和图2，图1为本发明背板组件第一实施例的主视示意图；图2为图1中背板组件的第一连接器、第一通孔和第三连接器、以及第二连接器、第二通孔和第三连接器的结构示意图。
在本发明第一实施例中，该背板组件包括相对设置的第一背板1和第二背板2，第一背板1的背面设有第一连接器5，第二背板2的背面对应设有与第一连接器5相插接的第二连接器6。第一背板1和第二背板2的正面选择性地设有供业务板3插接的第三连接器7、以及供交叉板4插接的第四连接器8。第一背板1和第二背板2均设有走线9，走线9、第一连接器5和第二连接器6将任一第三连接器7与任一第四连接器8连接。
本实施例背板组件通过在第一背板1的背面设置第一连接器5，在第二背板2的背面设置第二连接器6，第一连接器5和第二连接器6插接连接而将第一背板1的第二背板2连接；而且第一背板1和第二背板2的正面均设有第三连接器7和/或第四连接器8，业务板3可插接于第三连接器
7上，交叉板4可插接于第四连接器8上，并通过走线9、第一连接器5和第二连接器6电性连接任一第三连接器7和任一第四连接器8，而实现任一业务板3和任一交叉板4之间的连接，因此，相对于单面交叉系统，该背板组件增加了业务板3和交叉板4的数量，从而提高了通信设备的交叉容量。
参照图2，在本实施例中，进一步地，第一连接器5和第二连接器6相互插接，可以互为公母连接器，优选地，第一连接器5和第二连接器6均为直式连接器，采用直式连接器有利于减少信号损失，方便插接。第三连接器7或第四连接器8可以为公连接器和母连接器中的一种，只要可以通过该第三连接器7将业务板3安装在第一背板1上、通过该第四连接器8将业务板3安装在第二背板2上即可，同样该第三连接器7和第四连接器8优选为直式连接器。
参照图1，在本实施例中，进一步地，第一背板1和第二背板2的正面均设有第三连接器7和第四连接器8。
通过在第一背板1和第二背板2的正面上设置第三连接器7和第四连接器8，进而安装在第三连接器7上的业务板3和安装在第四连接器8的交叉板4的数量是单面交叉系统的业务板3和交叉板4的数量的两倍，由此可以大大提高通信设备的交叉容量。显然，在第一背板1和第二背板2上设置第三连接器7和第四连接器8的方式并不限于此，例如可以是，只在第一背板1的正面设置第三连接器7且只在第二背板2的正面设置第四连接器8或者只在第一背板1的正面设置第四连接器8且只在第二背板2的正面设置第三连接器7，该设置方式同样适用于本实施例，只要该背板组件上设置的业务板3和交叉板4的数量相对于单面交叉系统的业务板3和交叉板4的数量有所增加，而实现通信设备的交叉容量的提高即可。
在本实施例中，进一步地，走线9包括第一走线90和第二走线92，第一走线90将第位于同一背板上的第三连接器7与第四连接器8连接，第二走线92将位于同一背板上的第三连接器7和第四连接器8与第一连
接器5或第二连接器6连接。
该第二走线92经过相插接的第一连接器5和第二连接器6而连接不同的正面上的任一业务板3和任一交叉板4，减小了走线9长度，减少信号损失。
更进一步地，第一背板1和第二背板2的正面上沿各自的纵向依次设有第一区域、第二区域和第三区域，第三连接器7设于第一区域和第三区域上，第四连接器8设于第二区域上。
由于第三连接器7设于第四连接器8的两侧，进而安装在第三连接器7上的业务板3位于安装在第四连接器8上的交叉板4的两侧，因此第一背板1中连接业务板3和交叉板4的第一走线90可整齐规划，避免走线9交叉；同样地，第二背板2中连接业务板3和交叉板4的第一走线90可整齐规划，避免走线9交叉。
具体地，第一背板1的正面上的多个第三连接器7沿第一背板1的纵向排列成一组第三连接器7，一组第三连接器7供一业务板3插接，多组第三连接器7沿第一背板1的横向并排设置。第一背板1的正面上的多个第四连接器8沿第一背板1的横向排列成一组第四连接器8，一组第四连接器8供一交叉板4插接，多组第四连接器8沿第一背板1的纵向并排设置。第二背板2的正面上的多个第三连接器7沿第二背板2的纵向排列成一组第三连接器7，一组第三连接器7供一业务板3插接，多组第三连接器7沿第二背板2的横向并排设置。第二背板2的正面上的多个第四连接器8沿第二背板2的横向排列成一组第四连接器8，一组第四连接器8供一交叉板4插接，多组第四连接器8沿第二背板2的纵向并排设置。
参照图2，在本实施例中，进一步地，第一背板1上设有至少一个第一通孔10，一第一连接器5和一第三连接器7或一第四连接器8通过第一通孔10电性连接，第二背板2上设有至少一个第二通孔20，一第二连接器6和一第三连接器7或一第四连接器8通过第二通孔20电性连接。
一第一连接器5和一第三连接器7或一第四连接器8共用通孔设置，
可以尽可能地减小走线9长度，也可以减小过孔造成的阻抗不连续。在本实施例中，优选地，一第一连接器5和一第三连接器7共用第一通孔10设置，一第二连接器6和一第三连接器7共用第二通孔20设置。
参照图1，在本实施例中，在该背板组件中第一连接器5的插接部、第二连接器6的插接部为第三连接器7的插接部的一半，插接部为插孔或插脚。第一连接器5和第二连接器6具有m*n排插接部，第三连接器7具有M*N排插接部，其中，M＝m，N＝2n，且M、m、N、n均为自然数。
在相插接的一组第一连接器5和一组第二连接器6中，不同连接器的具体排布和连接方式为：
第一背板1和第二背板2的横向即为图1中的上下方向，一组第一连接器5包括自上而下成排设置的八个第一连接器5，其中，以两个连接的第一连接器5为第一单元，八个第一连接器5分成间隔设置的四个第一单元；一组第三连接器7包括自上而下成排间隔设置的四个第三连接器7，在第一背板1上第一单元上部的第一连接器5对应与第三连接器7的下半部分共用第一通孔10设置。一组第二连接器6包括自上而下成排设置的八个第二连接器6，其中，以两个连接的第二连接器6为第二单元，八个第二连接器6分成间隔设置的四个第二单元；一组第三连接器7包括自上而下成排间隔设置的四个第三连接器7，在第二背板2上第二单元下部的第二连接器6对应与第三连接器7的上半部分共用第二通孔20设置。
在本实施例中，进一步地，该背板组件还包括用于固定第一背板1和第二背板2的固定件(未图示)和用于定位第一背板1和第二背板2的定位件(未图示)。
参照图2及图3，图3为本发明背板组件第二实施例的主视图。本第二实施例的背板组件与第一实施例的背板组件的不同之处在于：
第一连接器5的插接部、第二连接器6的插接部和第三连接器77的插接部的数量均相同，插接部为插孔或插脚。具体地，第一连接器5具有
M*N排插接部，第二连接器6具有M*N排插接部，第三连接器7具有M*N排插接部；其中，M、N均为自然数，如图3所示。
在相插接的一组第一连接器5和一组第二连接器6中，不同连接器的排布和连接方式为：
在第一背板1中，一组第一连接器5包括自上而下成排间隔设置的四个第一连接器5，一组第三连接器7包括自上而下成排设置的四个第三连接器7，以连接的两第三连接器7为第一单元，四个第三连接器7分成间隔设置的两第一单元，两第一单元的中间部分与一第一连接器5共用第一通孔10设置。在第二背板2中，一组第二连接器6包括自上而下成排间隔设置的四个第二连接器6，一组第三连接器7包括自上而下成排设置的四个第三连接器7，以连接的两第三连接器7为第二单元，四个第三连接器7分成间隔设置的两第二单元，两第二单元的中间部分与一第二连接器6共用第二通孔20设置，其中，另两第一连接器5与共用第一通孔10的两第二连接器6插接、且与两第一连接器5首尾交错设置。
参照图2及图4，图4为本发明背板组件第三实施例的主视图。本第三实施例的背板组件与第二实施例的背板组件的不同之处在于：

参照图5及图6，图5为本发明背板组件第四实施例的主视图，图6为本发明背板组件第五实施例的主视图。本第四实施例和第五实施例的背板组件与上述三个实施例的不同之处在于：
第一背板1的第一连接器5和第三连接器7不共用通孔设置，第二背板2的第二连接器6和第三连接器7不共用通孔设置。即第一背板1上的第一连接器5与第三连接器7在第一背板1的纵向上呈错开设置，第二背板2上的第二连接器6与第四连接器8在第二背板2的纵向上呈错开设置。
具体地，在第四实施例中，在插接的一组第一连接器5和一组第二连接器6中，第一连接器5的插接部、第二连接器6的插接部和第三连接器7的插接部的数量均相同，插接部为插孔或插脚。
在第一背板1中，一组第一连接器5包括自上而下成排设置的四个第一连接器5，以连接的两第一连接器5为第一单元，四个第一连接器5分成间隔设置的两第一单元；一组第三连接器7包括自上而下成排相连设置的四个第三连接器7，两第一单元对应位于一组第三连接器7的上下两侧。在第二背板2中，一组第二连接器6包括自上而下成排设置的四个第二连接器6，以连接的两第二连接器6为第二单元，四个第二连接器6分成间隔设置的两第二单元；一组第三连接器7包括自上而下成排相连设置的四个第三连接器7，两第二单元对应位于一组第三连接器7的上下两侧。
具体地，在第五实施例中，其与上述第四实施例的不同之处在于：
