本申请要求在2021年11月26日提交中国专利局、申请号为202111420485.6、申请名称为“一种光背板互连装置及通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及信息通信技术领域，尤其涉及一种光背板互连装置及通信设备。
背景技术
背板是通信设备中的重要组成部分，背板一般安装在机柜的背面或中间位置，可以为单板或模块等提供信号连接和物理支撑。背板对通信设备的系统容量、散热风道、维护性能等方面起重要作用。背板可以分为电背板和光背板。
其中，电背板一般由印刷电路板、连接器和导销等部件组成。考虑电背板的组成部件的高可靠性、低失效率及承载的业务量较少等方面的原因，一般电背板直接固定在子架上，即电背板可以采用不可更换的方案。
光背板一般由光纤、光连接器、支撑结构件和导销构成，光背板的组成部件的可靠性和失效率与电背板相当。但是，由于光背板承载的业务量较多，且光纤端面对灰尘敏感等原因，在传输功率较高的情况下，光背板采用不可更换的方案，已经难以满足信号传输需求。然而，在相关技术中，由于其他部件对光背板的位置限制，需要将光背板固定在子架上，导致光背板无法更换。若出现光背板中某个通道损坏的情况，会影响业务传输效果，甚至会导致更换整个机柜。

在具体实施时，每一个交叉板在靠近单板的一侧设有第一电连接器，每一个单板的表面设有第二电连接器，每一个交叉板与任一单板之间通过第一电连接器和第二电连接器实现电信号连接。为了便于实现交叉板与单板之间的可插拔连接，可以在第一电连接器上设置簧片，并在第二电连接器上设置与该簧片匹配的触点；或者，在第一电连接器上设置触点，并在第二电连接器上设置与该触点匹配的簧片。这样，可以使第一电连接器与第二电连接器通过触点与簧片实现连接。当然，第一电连接器与第二电连接器也可以采用其他方式实现连接，此处不做限定。

在一种可能的实现方式中，每一个单板中，第二光连接器与第二电连接器分别位于单板不同的表面。这样，可以充分利用单板的上表面和下表面的空间，也使光背板上对应的第一光连接器和第三电连接器的位置更容易设置，便于实现光背板与单板之间的可插拔连接。当然，在光背板和单板的空间允许的情况下，第二光连接器与第二电连接器也可以设置在单板的同一表面，即都设置在单板的上表面或下表面。
在一种可能的实现方式中，光背板互连装置可以包括多个单板，组成至少一个单板组。每一个单板组包括两个单板，分别为第一单板和第二单板。每一个单板组中，第一单板与第二单板在第一方向上并排设置，第一单板在靠近第二单板的位置与光背板连接，第二单板在靠近第一单板的位置与光背板连接，第一方向为垂直于单板的方向。本申请实施例中，通过将第一单板与第二单板设置为在第一方向上并排设置，并且，第一单板和第二单板均在靠近中间的位置处与光背板连接，从而，可以增加光背板连接的单板的数量，增加光背板的槽位数量。
在每一个单板组中，第一单板在靠近所第二单板的位置设置有第二光连接器，第二单板在靠近第一单板的位置设有第二光连接器。光背板在对应每一个单板组的位置处设有两个第一光连接器，其中一个第一光连接器与第一单板的第二光连接器连接，另一个第一光连接器与第二单板的第二光连接器连接。

在具体实施时，在每一个单板组中，第一单板与第二单板的结构可以相同，例如，第一单板与第二单板中的线路或模块设置位置可以相同，第一单板与第二单板表面的第二光连接器的设置位置可以相同，这样，第一单板与第二单板的配件可以共用，可以减少配件加工成本。将每一个单板组中的单板与光背板连接时，可以使第一单板正插，第二单板反插，其中，第一单板正插可以理解为第一单板在上表面设置与光背板连接的第二光连接器，第二单板反插可以理解为第二单板在下表面设置与光背板连接的第二光连接器。

本申请实施例提供的光背板互连装置中，通过将每一个光背板设置为与任一单板相互正交，并且，每一个光背板的一个侧面与任一单板的一个侧面相对设置，各单板均位于任一光背板的同一侧，也就是说，光背板仅以一个侧面与任一单板连接，使得光背板的位置不受其他部件的限制，从而可以使光背板与单板之间实现可插拔连接，在光背板出现故障时，可以对光背板进行单独更换，无需更换整个机柜。并且，将每一个光背板设置为与任一单板可插拔连接，可以更灵活、更容易地更换光背板。
为了更清楚的示意光背板互连装置中各部件的方位，图1和图2中标识出了xyz坐标系，继续参照图1和图2，光背板互连装置中的各单板12平行于xy平面时，可以将光背板11设置为平行于yz平面，以使光背板11与单板12相互正交。并且，由于各单板12均位于光背板11的同一侧，光背板11的一个侧面朝向各单板12，从而，使光背板11的位置不受其他部件的限制。在具体实施时，可以按照图中箭头S1的方向安装光背板11，当光背板11需要更换时，可以按照图中S2的方向拆除光背板11。图1中以各单板12位于光背板11的左侧，且单板12水平放置，光背板11竖直放置为例进行示意，在具体实施时，可以根据实际需要设置光背板11和单板12的位置，此处不做限定。
本申请实施例中的单板12可以为任何能够传输光信号的单板，例如，该单板可以为业务处理板或交叉板。例如，上述单板12可以为用于接入业务和处理业务的线卡(Line Card，LC)。
在本申请的一些实施例中，如图1和图2所示，光背板互连装置可以包括沿第一方向(例如图中箭头z所示的方向)排列的多个单板12，第一方向为垂直于单板12的方向。将光背板互连装置中的各单板12平行设置，可以便于将各单板12与光背板11进行互连。可选地，光背板11可以与至少两个单板12连接，这样，通过光背板11进行光信号传输，可以实现至少两个单板12之间的光信号传输。可选地，光背板互连装置中的多个单板12可以均为业务处理板；或者，光背板互连装置中的多个单板12可以均为交叉板；或者，光背板互连装置中的多个单板12可以既包括业务处理板也包括交叉板。

此外，通过在光背板互连装置中设置多个光背板11，可以起到冗余保护作用，具体地，可以将至少一个光背板11作为工作背板，其余的光背板11作为冗余背板。当工作背板正常工作时，冗余背板可以处于待机状态，当工作背板出现故障时，可以控制冗余背板从待机状态切换为工作状态，以替代冗余背板的功能，保证光背板互连装置能够正常运行。并且，通过设置冗余背板，当工作背板出现故障时，可以在不断开业务的情况下，实现光背板的现网更换。

在具体实施时，交叉板15可以接收单板12传输的电层业务，并对接收的电层业务进行交叉调度。本申请实施例中，通过在光背板互连装置中设置光背板11和交叉板15，可以使光背板互连装置同时具有处理光业务和电业务的功能。
可选地，在本申请实施例中的光背板互连装置中，交叉板15的数量可以是一个或多个，可以根据实际需要对交叉板15的数量进行设置，此处不做限定。
继续参照图5和图6，在一种可能的实现方式中，光背板互连装置可以包括多个交叉板15，各交叉板15分布于光背板互连装置中所有光背板11的两侧，即可以使光背板11位于中间位置。可选地，光背板互连装置中的交叉板15的数量可以为偶数，各交叉板15可以对称分布于光背板互连装置中所有光背板11的两侧。
图7为本申请实施例提供的光背板互连装置的另一立体结构示意图，图8为图7所示的立体结构示意图的顶视图。图5和图6中，以光背板互连装置中设有一个光背板11为例进行示意，光背板互连装置中的各交叉板15分布于该光背板11的两侧。如图7和图8所示，光背板互连装置中也可以设置多个光背板11，图7和图8中以光背板互连装置中设置两个光背板11为例，可以根据实际需要设置光背板11的数量。光背板互连装置中的各交叉板15可以分布于所有光背板11的两侧。
当然，在具体实施时，光背板互连装置中的多个交叉板也可以分布于上述至少一个光背板的同一侧，此处不做限定。
在具体实施时，如图5和图6所示，每一个交叉板15在靠近单板12的一侧设有第一电连接器16，每一个单板12的表面设有第二电连接器17。每一个交叉板15与任一单板12之间通过第一电连接器16和第二电连接器17实现电信号连接。为了便于实现交叉板15与单板12之间的可插拔连接，可以在第一电连接器16上设置簧片，并在第二电连接器17上设置与该簧片匹配的触点；或者，在第一电连接器16上设置触点，并在第二电连接器17上设置与该触点匹配的簧片。这样，可以使第一电连接器16与第二电连接器17通过触点与簧片实现连接。当然，第一电连接器16与第二电连接器17也可以采用其他方式实现连接，此处不做限定。
在图5和图6中，以第一电连接器16固定于交叉板15的表面靠近单板12的边缘处为例进行示意，在具体实施时，第一电连接器16也可以设置在交叉板15靠近单板12一侧的侧面，可以根据实际需要设置第一电连接器16的位置，此处不做限定。
图9为本申请实施例提供的光背板互连装置的另一立体结构示意图，图10为图9所示的立体结构示意图的顶视图。如图9和图10所示，在一种可能的实现方式中，光背板11可以集成电信号传输模块(图中未示出)，每一个光背板11的在靠近单板12的一侧设有第一光连接器13和第三电连接器18，每一个单板12的表面设有第二光连接器14和第二电连接器17。光背板11与单板12通过第一光连接器13和第二光连接器14实现光信号连接，光背板11与单板12通过第三电连接器18和第二电连接器17实现电信号连接。
本申请实施例中，通过将电信号传输模块集成到光背板11中，并在光背板11和业务传输板12上分别设置光连接器和电连接器，可以使光背板11集成了传输光信号和电信号的功能，从而可以省去光背板互连装置中的交叉板，减小光背板互连装置占用的空间。并且，由于省去了交叉板，可以使单板12侧面设置的部件较少，能够增大风量，有利于提高通信设备中各部件的散热效果。
继续参照图9和图10，每一个单板12中，第二光连接器14与第二电连接器17分别 位于单板12不同的表面。这样，可以充分利用单板12的上表面和下表面的空间，也使光背板11上对应的第一光连接器13和第三电连接器18的位置更容易设置，便于实现光背板11与单板12之间的可插拔连接。当然，在光背板11和单板12的空间允许的情况下，第二光连接器14与第二电连接器17也可以设置在单板12的同一表面，即都设置在单板12的上表面或下表面。
图11为本申请实施例提供的光背板互连装置的另一立体结构示意图，图12为图11所示的立体结构示意图的顶视图。如图11和图12所示，光背板互连装置可以包括多个单板，组成至少一个单板组12M。其中，每一个单板组12M包括两个单板，分别为第一单板12a和第二单板12b。每一个单板组12M中，第一单板12a与第二单板12b在第一方向(如图中箭头x所示的方向)上并排设置，第一单板12a在靠近第二单板12b的位置与光背板11连接，第二单板12b在靠近第一单板12a的位置与光背板11连接。第一方向为垂直于单板的方向。
对比图1和图11可以明显看出，本申请实施例中，通过将第一单板12a与第二单板12b设置为在第一方向上并排设置，并且，第一单板12a和第二单板12b均在靠近中间的位置处与光背板11连接，从而，可以增加光背板11连接的单板的数量，增加光背板11的槽位数量。
在每一个单板组12M中，第一单板12a在靠近所第二单板12b的位置设置有第二光连接器14，第二单板12b在靠近第一单板12a的位置设有第二光连接器14。光背板11在对应每一个单板组12M的位置处设有两个第一光连接器13，其中一个第一光连接器13与第一单板12a的第二光连接器14连接，另一个第一光连接器13与第二单板12b的第二光连接器连接14。
本申请实施例中的光背板互连装置可以应用于通信设备中，一般在通信设备中可以设置风扇F，以降低通信设备中各部件的温度，风扇F形成的风向可以如图中箭头f所示，通过将单板组12M中的第二光连接器14集中在中间位置，这样，可以使光背板11上的第一光连接器13也比较集中，可以使光背板11在第一方向上的宽度较窄，减小光背板11占用的空间。因而，光背板11不会遮挡风道，从而可以增大风量，使通信设备中各部件的散热效果较好。
继续参照图11和图12，在具体实施时，在每一个单板组12M中，第一单板12a与第二单板12b的结构可以相同，例如，第一单板12a与第二单板12b中的线路或模块设置位置可以相同，第一单板12a与第二单板12b表面的第二光连接器14的设置位置可以相同，这样，第一单板12a与第二单板12b的配件可以共用，可以减少配件加工成本。将每一个单板组12M中的单板与光背板11连接时，可以使第一单板12a正插，第二单板12b反插，其中，第一单板12a正插可以理解为第一单板12a在上表面设置与光背板11连接的第二光连接器14，第二单板12b反插可以理解为第二单板12b在下表面设置与光背板11连接的第二光连接器14。
图13为本申请实施例中光背板互连装置的一种顶视结构示意图，如图13所示，上述单板为业务处理板，本申请实施例中的光背板互连装置还可以包括：至少两个交叉板，分为第一交叉板组15M和第二交叉板组15N，其中，第一交叉板组15M包括至少一个交叉板15，第二交叉板组15N包括至少一个交叉板15。每一个交叉板15位于单板朝向光背板11的一侧，且每一个交叉板15与任一单板相互正交。第一交叉板组15M与第二交叉板组 15N分别位于光背板11的两侧。在每一个单板组12M中，第一单板12a与第一交叉板组15M中的交叉板15可插拔连接，第二单板12b与第二交叉板组15N中的交叉板15可插拔连接。
也就是说，光背板互连装置中的各交叉板15与光背板11位于单板的同一侧，并且，各交叉板15与光背板11平行设置，这样，可以使单板在同一侧与各交叉板15和光背板11连接，便于对单板上的各种连接器的位置进行设置，也可以较容易地更换光背板11或交叉板15。在具体实施时，交叉板15可以接收单板12传输的业务，并对接收的业务进行交叉调度。本申请实施例中，通过在光背板互连装置中设置光背板11和交叉板15，可以使光背板互连装置同时具有处理光业务和电业务的功能。
继续参照图13，本申请的一些实施例中，光背板互连装置还可以包括：位于单板与光背板11之间的电背板19，每一个交叉板15位于电背板19远离单板的一侧。电背板19与每一个单板组12M中的第一单板12a和第二单板12b可插拔连接，电背板19与第一交叉板组15M中的各交叉板15可插拔连接，电背板19与第二交叉板组15N中的各交叉板15可插拔连接。本申请实施例中，通过设置电背板19，电背板19一侧的表面与第一单板12a和第二单板12b连接，电背板19另一侧的表面与第一交叉板组15M和第二交叉板组15N中的各交叉板15连接，从而，可以使第一交叉板组15M中的各交叉板15，与第二交叉板组15N中的各交叉板15实现电连接，这样，第一交叉板组15M与第二交叉板组15N中的任意两个交叉板15之间都能够实现电信号传输。
图14为本申请实施例中电背板的平面结构示意图，结合图13和图14，电背板19上设有分别与光背板11中的各第一光连接器13的位置对应的多个开孔U，第一光连接器13穿过对应位置处的开孔U与第二光连接器14连接。通过在电背板19上设置多个开孔U，可以使光背板11中的各第一光连接器13穿过开孔U后与第二光连接器14连接，从而，可以实现将电背板19设置在光背板11与单板之间的位置，可以合理利用光背板互连装置中的空间，并且，电背板19不影响光背板11的位置，保证光背板11能够与单板之间可插拔连接。
继续参照图13，在一种可能的实现方式中，每一个交叉板15在靠近单板的一侧设有第一电连接器16，每一个单板的表面设有第二电连接器17，电背板19在靠近交叉板15的一侧设有第四电连接器20，电背板19在靠近单板的一侧设有第五电连接器21，电背板19与交叉板15通过第一电连接器16和第四电连接器20实现电信号连接，电背板19与单板通过第二电连接器17和第五电连接器21实现电信号连接。
为了便于实现交叉板15与电背板19之间的可插拔连接，可以在第一电连接器16上设置簧片，并在第四电连接器20上设置与该簧片匹配的触点；或者，在第一电连接器16上设置触点，并在第四电连接器20上设置与该触点匹配的簧片。这样，可以使第一电连接器16与第四电连接器20通过簧片与触点实现连接。当然，第一电连接器16与第四电连接器20也可以采用其他方式实现连接，此处不做限定。
为了便于实现单板与电背板19之间的可插拔连接，可以在第二电连接器17上设置簧片，并在第五电连接器21上设置与该簧片匹配的触点；或者，在第二电连接器17上设置触点，并在第五电连接器21上设置与该触点匹配的簧片。这样，可以使第二电连接器17与第五电连接器21通过簧片与触点实现连接。当然，第二电连接器17与第五电连接器21也可以采用其他方式实现连接，此处不做限定。
图15为本申请实施例中光背板的立体结构示意图，如图15所示，本申请实施例中的光背板互连装置还可以包括：子架(图中未示出)，子架中设有槽轨，光背板11上设有与槽轨匹配的滑轨22。这样，可以便于将光背板11插入子架中实现与单板的连接，并且，也可以使光背板11较容易地从子架中拔出。为了便于将光背板11取出，可以在光背板11的侧面设置拉环24，在具体实施时，也可以采用扳手或其他部件替代拉环24。
此外，光背板互连装置还可以包括：至少一个固定件23，固定件23用于将光背板11可拆卸地固定于子架上，可选地，可以在光背板11中设置通孔，固定件23可以穿过光背板11与子架固定，从而将光背板11固定在子架上，防止在加工或运输过程中，光背板11脱落。当需要更换光背板11时，可以将固定件23拆除，使光背板11顺利拔出，保证光背板11能够顺利更换。例如，该固定件23可以为松不脱或螺杆等。
基于同一技术构思，本申请实施例还提供了一种通信设备，该通信设备可以包括：上述任一光背板互连装置，以及壳体。该通信设备可以为光通信设备、路由器、交换机、服务器等。由于上述光背板互连装置中的光背板与单板可插拔连接，在光背板出现故障时，可以对光背板进行单独更换，无需更换整个机柜。光背板互连装置的结构比较灵活、可靠性较高。因而，包括该光背板互连装置的通信设备的结构也比较灵活、可靠性较高。
