如图2至图8所示，根据本发明的实施例，提供了一种通讯交换设备包括业务板卡10、交换板卡20和互连部件30。互连部件30为多个，多个互连部件30上均设置有多个第一连接器31和多个第二连接器32。互连部件30通过第一连接器31与业务板卡10相连接。互连部件30通过第二连接器32与业务板卡10和交换板卡20相连接。多个第一连接器31中的任一个第一连接器31与多个第二连接器32可以相导通，业务板卡10与交换板卡20通过第一连接器31或第二连接器32以及互连部件30内设置的线路相连接并进行信号交换。当然，业务 板卡10与交换板卡20也可以通过第一连接器31和第二连接器32以及互连部件30内设置的线路相连接并进行信号交换。
本发明提出了通讯设备的板到板互连方法，多个互连部件30实现所有业务板卡10到交换板卡20之间的互相连接需求，增加了设备风道，能够极大的改善设备散热问题，简化互连设计，从而降低了本发明的功耗和成本。
在本实施例中，业务板卡10和交换板卡20之间有业务互通需求。如图3所示，业务板卡10和交换板卡20之间的光信号的逻辑互连关系。另外，相邻的业务板卡10也有光信号互连通路。相邻的交换板卡20也有光信号互连通路。以及，所有业务板卡10和交换板卡20之间需要供电连接。
互连部件30可以采用波导嵌入式PCB板。波导嵌入式PCB板为硬质板不需要配备1对1的固定框40，能够直接固定在设备机框上。波导嵌入式PCB板中，通过PCB中的波导通路传输光信号，多个与业务板卡10与交换板卡20通过光信号连接器进行光信号交换。
波导嵌入式PCB板中，通过PCB中的金属通路传输电信号，对业务板卡10与交换板卡20供电。
如图3所示，业务板卡10和交换板卡20之间的光信号的逻辑互连关系。该设备有N块业务板卡10和M块交换板卡20，图3示出了任意业务板卡10和任意交换板卡20间都存在光信号互连通路。
实现上述实施例的具体操作步骤为：
首先将图3中将业务板卡10到交换板卡20的光信号互连关系划分为如图4所示多个子互连关系。
本实施例划分方式根据M个交换板卡20不同划分为图4的M个子互连关系。每个子互连包含一个交换板与N个业务板卡10的所有互连。所以，业务板卡10和交换板卡20互连需要M个互连部件30。其中，划分原则为按照交换板卡20的个数进行划分。将一个交换板卡20与所有业务板卡10的所有互连划分为一个子互连。还可以将一个交换板卡20与所有业务板卡10的所有互连划分为多个子互连。
如图7和图8所示，互连部件30的连接，总共需要M个对应的互连部件。互连部件30还可以采用光纤软板制作。
互连部件30包含的第一连接器31采用光信号连接器对接相应业务板卡10的光信号连接器，互连部件30包含的第二连接器32光信号连接器对接相应交换板卡20的光信号连接器。
进一步的，为了减小光纤软板互连板的面积，互连部件30内光纤材料可以采用弯曲半径小于10mm的抗微弯光纤材料，可以将光纤软板卷曲，如图8所示的圆柱状。这样可以减小设备的深度要求，减短风道。另外，互连部件30中互连板也可以采用光纤互连，再将多根光纤捆扎成图8的圆柱状。
在本实施例中，互连部件30还可以包含互连板并与业务板卡10对接光信号连接器或是信号连接器，与交换板卡20对接光信号连接器或是电信号连接器。
如图2所示，在本实施例中，业务板卡10为多个，多个业务板卡10相平行地设置。这样设置能够保证多个业务板卡10之间具有良好的通风通道。交换板卡20为多个，多个交换板卡20相平行地设置，业务板卡10与交换板卡20也相互平行。这样设置能够保证多个交换板卡20之间具有良好的通风通道。同时也增加了本发明的使用寿命。且相邻的业务板卡10和相邻的交换板卡20之间具有间隙。
如图5和图6所示，在本实施例中，通过互连部件30连接的业务板卡10和交换板卡20相互平行，固定框40固定设置在互连部件30上。其中，多个业务板卡10设置与靠近业务板卡10的交换板卡20之间的设置距离大于业务板卡10之间的设置距离或是大于交换板卡20之间的设置距离。且互连部件30与任意的第一连接器31相导通。或是互连部件30与任意的第二连接器32相导通。
进一步地，如图7所示，固定框40上设置有多个固定件41，在竖直方向上的一组固定件41对应互连部件的一个子互连部件，多个固定件41将业务板卡10和交换板卡20与互连部件30相连接。
如图8所示，在本实施例中的互连部件30为可卷曲的软板结构。其中，软板结构的互连部件30可以卷曲成柱状结构的互连部件。这样可以有效的减小通讯交换设备的内部空间，同时曾大了风道的出口，提高了交换设备的性能。
如图9所示，在本发明的第二实施例中，多个业务板卡10组成业务板卡组，多个交换板卡20组成交换板卡组，业务板卡组位于交换板卡组的一侧。
在本发明的第二实施例中，多个业务板卡10组成业务板卡组，多个交换板卡20组成交换板卡组，业务板卡组与交换板卡组相垂直。
其中，多个互连部件30平行地设置在业务板卡10与交换板卡20的同侧。这样设置能够增加业务板卡10与交换板卡20之间的连接强度。
如图11所示，在本实施例中，互连部件30与业务板卡10和交换板卡20之间还设置有固定框40，固定框40上设置有用于固定业务板卡10和交换板卡20的固定件41，其中，固定件41为卡槽。这样设置进一步地加强了业务板卡10与交换板卡20之间的连接强度。使得本发明使用起来更加安全可靠。能够有效地增加通讯交换设备的使用寿命。其中，固定件包含与业务板卡10对接的光紧固件或电紧固件，与交换板卡对接的光紧固件或电紧固件。
本实施例中，所有互连部件30对应同一个固定框40。固定框40位于设备中间，固定所有互连部件30。
其中，固定框40居中，互连部件30插入到固定框40中。风机50放置在最后。通讯交换设备的风道采用前入风，后出风。
当需要改变设备中交换板卡20和业务板卡10直接的互连关系时，可以直接更换不同互连关系甚至不同材质的互连部件30来实现。例如，其中几块波导嵌入式PCB板可以更换成光纤软板。
其中，互连部件30采用软质材料制作时，例如光纤或者光纤软板等，需要增加固定框40。本实施例，一个光纤软板互连部件30对应一个固定框40。
固定框40的框架采用硬质材料制作窗户型的框架，例如可以采用金属或硬质塑料等。将互连部件30捆扎或者用螺丝固定在固定框40的框架上。
光纤软板上的光信号连接器固定在紧固件处，连接器固定在紧固件处。紧固件可以是第一连接器31或第二连接器32，也可以是金属加固件。
在本实施例中，这样设置可以使得业务板卡10和交换板卡20与互连部件30之间实现可拆卸连接，也可以直接将业务板卡10和交换板卡20插入到卡槽中与设置在互连部件30内部的导线相导通。这样设置操作简单、方便，能够提高生产效率的同时还可以降低维修成本，即要更换坏掉的业务板卡10或是交换板卡20时，直接将其拔出或是插入即可。
当业务板卡10插入设备之后，业务板卡10光信号连接器连接到紧固件处。当交换板卡20插入设备之后，交换板卡20光信号连接器连接到紧固件处。继而实现了业务板卡10和交换板卡20间的光信号就通过互连部件中的通路互连了。
如图9所示，通讯交换设备包含业务板卡10交换板卡20，业务板卡10和交换板卡20全部从正面插入设备。互连部件30和固定框40如图9放置。设备从上到下单板多，距离长。设计设备风道采用前入风，后出风，则风道短，风口大。可以将风机50放置在最后，抽风或者吹风。极大的改善设备散热问题，简化互连设计，从而降低设备功耗。其中，设备业务板卡10在设备中竖插，交换板在设备中横插。
如图12所示，所示互连部件30提供相邻的业务板卡和相邻的交换板卡的互连，以及供电连接。
如图13所示，本实施例中，划分方式根据N个业务板卡10不同划分为N个子互连关系。每个子互连为一个业务板与M个交换板的互连。所以，业务板和交换板互连需要N个互连部件30。
如图8所示，互连部件30的连接，总共需要N个对应的互连部件30。互连部件30中的互连板采用波导嵌入式PCB板制作。互连部件30包含的光信号连接器对应业务板卡10的光信号连接器，互连部件30包含的光信号连接器对应交换板卡20的光信号连接器。互连板采用波导嵌入式PCB板可以直接固定在设备机框上。
在本实施例中，通讯交换设备还包括风机50，风机50位于业务板卡10和交换板卡20的相对侧，风机50与业务板卡10和交换板卡20之间形成多个横向风道。这样设置能够极大的改善设备散热问题，简化互连设计，从而降低设备功耗和成本。
如图10至图13所示，在本发明的第三实施例中，通讯交换设备还包括风机50，风机50位于业务板卡10或交换板卡20的相对侧，风机50与业务板卡10和交换板卡20之间形成多个横向风道。这样设置能够极大的改善设备散热问题，简化互连设计，从而降低设备功耗和成本。其中，风机50可以为多个，风机50可以设置在该通讯交换设备上方和下方，也可以只设置在上方或是下方的位置，这样能够保证该通讯交换设备具有良好的散热和通风性能。
在本实施例中，业务板卡10上设置有第三连接器11，业务板卡10通过第三连接器11与互连部件30相连接。交换板卡20上设置有第四连接器21，交换板卡20通过第四连接器21与互连部件30相连接。这样设置有利于业务板卡10、交换板卡20和互连部件30之间具有良好的导通性能。
其中，互连部件30为硬质板状结构、柱状结构或为可卷曲的软板结构。互连部件30还可以为全光信号互通的光纤软板、聚合物光波导PCB板或光电混合印制板。这样可以有效的减小通讯交换设备的内部空间，同时曾大了风道的出口，提高了交换设备的性能。
