为了缓解设备交换容量和互连瓶颈, 在最近几年涌现出许多新的系 统和解决方案,其中在现有交换芯片总线速率和交换容量固定的情况下, 采用双面槽位中间背板是解决大容量瓶颈的方法之一。
现有技术双面插背板实现方法是: 中间背板前端面分别插设若干前 单板, 中间背板后端面分别插设若干后单板, 前后单板插设于中间背板 后, 每个单板的槽位互相平行且相互错位。 如图 1所示, 槽位单板 1和 槽位单板 2在背板结构上相互错位且平行, 槽位单板 2和槽位单板 3在 背板结构上相互错位且平行。 由于槽位单板 2对接的连接器的存在, 槽 位单板 2和槽位单板 3之间存留了较宽空隙。 发明人在实现本发明的过程中, 发现现有技术至少存在以下缺点: 现有技术为了避免前后单板槽位上的引脚重叠, 在中间背板结构上, 将 前后单板槽位设置为相互错位且平行, 使用时将前后单板插设于前后单 板槽位中。 虽然现有技术双面插背板结构和单面槽位背板相比, 提高了 背板单板槽位数量和交换容量。 但是, 现有技术双面插背板中若干个前 单板或若干个后单板之间存在较宽空隙, 结构空间利用率仍然较低, 且 双面插背板中单面槽位数量较少, 走线通道被连接器基本占用。 发明内容
本发明的目的在于, 提供一种双面插背板及具有该双面插背板的通 信设备,该双面插背板可以提供更大的业务交换容量和更多的单板槽位。
本发明的技术解决方案是: 一种双面插背板, 包括: 中间背板, 中 间背板前端面插设有至少一个前单板槽位连接器, 中间背板后端面插设 有至少一个后单板槽位连接器, 其中:
所述中间背板前端面至少具有用于插设前单板槽位连接器上的电性 插针的第一插脚、 第二插脚;
所述中间背板后端面至少具有用于插设后单板槽位连接器上的电性 插针的第三插脚;

后单板槽位连接器具有至少一第三电性插针, 所述后单板槽位连接 器自中间背板后端面第三插脚处向中间背板内部插设第三电性插针; 所述中间背板后端面的第三插脚位于所述中间背板前端面的第一插 脚与第二插脚的连接线段正对于中间背板后端面的线段上。
一种通信设备, 该通信设备包括上述双面插背板。
上述技术方案具有如下的优点: 通过将中间背板后端面的第三插脚 位于所述中间背板前端面的第一插脚与第二插脚的连接线段正对于中间 背板后端面的线段上, 使得双面插背板的前单板槽位连接器与后单板槽 位连接器在中间背板同一纵向位置上可以部分或者完全重叠, 使得双面 插背板中单板槽位连接器可以密集设置, 提高了双面插背板结构空间利 用率。 附图说明

在本发明实施例一中, 前单板槽位连接器 230与后单板槽位连接器 250可以是插入式电连接器或贴片式电连接器中的任一一种。可以理解, 本实施例中所说的第一插脚 211、第二插脚 213、第三插脚 215和第一电 性插针 231、 第二电性插针 233、 第三电性插针 251中, "第一"与 "第 二" 的限制是为了方便说明, 以区分若干个插脚和插针。
请一并参阅图 4, 本发明实施例二所揭露了另外一种双面插背板, 其包含 3个前单板槽位连接器和 3个后单板槽位连接器。 前后单板槽位 连接器分别用于插设 6个单板 290。

可选的, 前后单板槽位连接器的电性插针不限于垂直插设于中间背 板 210内部, 其也可以呈一定角度斜插入中间背板内部。 例如, 前单板 槽位连接器与后单板槽位连接器的电性插针与中间背板表面呈一定角度 斜插入中间背板内部。 中间背板后端面的第三插脚位于中间背板前端面 的第一插脚与第二插脚的连接线段正对于中间背板后端面的线段上。 同 样如此设计也可以使得双面插背板中前后单板槽位连接器可以密集设 置, 提高了双面插背板结构空间利用率。
前后单板槽位连接器部分重叠或完全重叠, 使得前后的单板槽位排 布和结构设计没有限制,前后单板业务槽位结构可以做到一致或不一致, 可以实现中间背板结构多样化。 可选的, 在实施例一中第一电性插针与 第三电性插针的接入信号不同。 或者, 前后单板槽位连接器重叠部分的 管脚(如实施例一中的第一插脚 211、第二插脚 213 )与后面槽位的连接 器管脚 (如实施例一中的第三插脚 215 ) 对信号作用定义不同, 而且重 叠区域的管脚可以实现与中间背板任意槽位连接器管脚的业务互连, 进 而提高中间背板同一位置的连接器管脚密度, 能够实现集中交换、 MESH (网格网状的网络系统) 、 对偶 (相邻槽位业务互连) 等各类业务交换 架构, 大大提升线卡槽位接入容量和交换槽位的业务交换容量。
为实现前后单板槽位连接器重叠部分的管脚与后面槽位的连接器管 脚互联互通, 实施例一和二中所揭露的双面插背板中, 双面插背板前后 单板的业务互连可以通过背板走线、 盲孔、 通孔或者埋孔实现。 前单板 槽位连接器或后单板槽位连接器分别具有若干电性插针, 每个单板槽位 连接器的若干电性插针之间部分或全部通过埋设于中间背板内部的布线 电性连接。这里也不限于埋设于布线,也可以通过中间背板内部的通孔、 盲孔、 埋孔或布线中的一种或多种方式电性连接。 如图 5所示, 中间背 板 210内部设置有布线 217和布线 219, 中间背板 210前端面开设有盲 孔 212, 后端面开设有盲孔 214, 中间背板 210于盲孔 212和盲孔 214 的中间部开设有通孔 216。 其中, 中间背板 210的盲孔 212是前单板槽 位连接器管脚所要插入的连接器孔。 中间背板 210的盲孔 214是后单板 槽位连接器管脚所要插入的连接器孔。 布线 217电性连接盲孔 212和通孔 216,布线 219电性连接通孔 216 和盲孔 214。 如果前单板槽位连接器管脚和后单板槽位连接器管脚需要 进行业务互连, 前单板槽位连接器管脚信号可以通过盲孔 212, 后经过 布线 217、 通孔 216、布线 219, 最后到达盲孔 214, 从而实现业务互连。 当然实现盲孔 212到盲孔 214之间的互联还可以有多种, 例如通过中间 背板内的埋孔或多个通孔和多个布线之间实现电性连接即可实现, 在此 不再赘述。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分 流程, 是可以通过计算机程序来指令相关的硬件来完成, 所述的程序可 存储于一计算机可读取存储介质中, 该程序在执行时, 可包括如上述各 方法的实施例的流程。 其中, 所述的存储介质可为磁碟、 光盘、 只读存 储记忆体(Read- Only Memory, ROM)或随机存储记忆体 ( Random Access Memory, RAM) 等。
以上所述仅为本发明的几个实施例, 本领域的技术人员依据申请文 件公开的可以对本发明进行各种改动或变型而不脱离本发明的精神和范 围。
