Description

测试工装 技术领域
本申请涉及但不限于电子设备技术领域。
背景技术
在通讯行业中，插箱被广泛的使用。插箱风道内的各种板件(包括被测元件和风阻元件)阻挡其内部通过的过流风，影响着过流风的风速和风向，这也是插箱风道内影响被测元件散热的主要原因。
相关技术的被测元件散热测试方法有：
一、不使用测试工装，将被测元件放置在外面，外置风扇向被测元件吹风来检测被测元件的温度值，以此来反映被测元件的散热情况；
二、使用具有风扇组件的测试工装，安装面板使面板覆盖安装口、同时安装好被测元件(但并不安装分隔板和风阻元件)，以此种方式来检测被测元件的温度值，以此反映测元件的散热情况；
三、使用具有风扇组件的测试工装，使用被测元件和风阻元件(模拟实际插箱的安装结构)来检测被测元件的温度值，以此反映测元件的散热情况。
上述三种测试方法存在的问题如下：
第一种和第二种测试方法，被测元件处的风速和风向与使用实际板件会存在一定的差异，导致被测元件上的温度值测试不准确；另外，第二种测试方法测试工装上并不安装风阻元件和分隔板，其与实际插箱的安装结构并不相符合，最终会导致被测元件的温度值测试不准确；
第三种测试方法，被测元件一般要在其它板件开发完成之后才能测试，开发进度不能与其它板件同步进行，会影响整体项目的开发进度；而且也存在测试工装上安装风阻元件的位置与实际插箱安装风阻元件的位置不一定完全相同，存在有测试工装上实际应定位风阻元件的位置却不存在能够定位风阻元件的定位结构的问题，致使其与实际插箱的安装结构并不相符合，最终 也会导致被测元件的温度值测试不准确。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。

可选地，所述测试工装还包括：分隔板，沿所述风道的轴向安装于所述风道内、并通过其一组相对的边与所述风道的一组相对的内侧壁面抵触；其中，所述分隔板的板面为所述风阻元件安装区域面。

当然，被测元件也能够通过其他的可代替元件来进行取代，通过该可替代原件测试后的温度值来反映被测元件的温度测试值，也可实现本申请的目的。
