Description

光模块测试结构及装置 技术领域
本申请涉及光通信技术领域，尤其涉及一种光模块测试结构及装置。
背景技术
光模块是进行光电和电光转换的光电子器件，光模块的发送端把电信号转换为光信号，接收端把光信号转换为电信号。在光模块销售前，会对光模块进行测试，确保其具有良好的性能。
现有的光模块测试结构主要由散热器、光模块笼子和卡扣组成，将散热器通过卡扣固定在光模块笼子上，其结构如图1所示。将光模块插入到光模块笼子中，光模块在插入光模块笼子的过程中，将散热器顶起，实现在测试时光模块与散热器的接触，使得散热器对测试过程中的光模块进行散热。在测试完成后，将光模块从光模块笼子中拔出。
发明人发现，现有技术的测试结构至少存在以下问题：无法在散热器与光模块的接触面上增加导热垫，影响散热性能；在光模块插拔的过程中，光模块会与散热器之间形成相对滑动，光模块与散热器的接触面会被刮伤，从而影响光模块的质量。
发明内容
本申请实施例提供一种光模块测试结构及装置，能够解决光模块在测试时易被散热器刮伤的问题，从而提高光模块测试后的良品率。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种光模块测试结构。该测试结构包括：散热器和固定在基板上的光模块笼子，散热器连接在光模块笼子上。还包括浮动支撑机构，浮动支撑机构包括第一推动机构和第二推动机构，第一推动机构一端连接在基板上，另一端与第二推动机构的一端连接，第二推动机构的另一端与散热器活动连接，第一推动机构运动可带动第二推动机构沿第一方向作往复运动，第二推动机构可带动散热器沿第一方向作往复运动。
在此基础上，浮动支撑机构包括第一推动机构和第二推动机构，第一推动机构的一端连接在基板上，另一端与散热器活动连接，通过推动第一推动机构运动，带动与第一推动机构相连的第二推动机构沿第一方向作往复运动，第二推动机构带动与其相连的散热器沿第一方向作往复运动。
本实施例中的第一方向在对光模块进行测试时可以是竖直方向，通过推动第一推动机构和第二推动机构，使得散热器相对光模块笼子在竖直方向上上升，此时将光模块插入到光模块笼子中，由于散热器被第二推动机构带动着上升，因此散热器与光模块之间存在一定的间隙，光模块插入光模块笼子时不会与散热器相接触，避免了散热器刮伤光模块。在光模块插入到预设位置时，推动第一推动机构和第二推动机构使得散热器相对光模块笼子在竖直方向上下降，使得散热器的底部与光模块相接触，实现 对测试过程中的光模块进行散热。在需要将光模块从光模块笼子拔出时，再次推动第一推动机构和第二推动机构使得散热器相对光模块笼子在竖直方向上上升，实现在光模块拔出过程中与散热器保持一定间隙，防止拔出过程中散热器刮伤光模块。
通过设置浮动支撑机构，可以使得该测试结构在测试不同光模块时，在光模块插入和拔出光模块笼子时，只需调节浮动支撑机构使散热器与每个光模块之间保持间隙即可，无需根据每一个光模块组装相应的散热器，实现了对光模块的大批量测试。
可选地，散热器沿第一方向作往复运动的运动行程为1mm-2mm。在此基础上，由于散热器一般是通过固定结构连接在光模块笼子上的，因此散热器作往复运动的运动行程受限。通过第二推动机构将散热器沿第一方向推动主要是为了在光模块的插入和拔出过程中与光模块保持间隙，因此将散热器作往复运动的运动行程设置为1mm至2mm，既不会影响散热器与光模块笼子之间的连接，同时也使得散热器与插拔过程中的光模块保持了间隙，避免了散热器对光模块的刮伤。
一种可能的设计方案中，第一推动机构包括设置于光模块笼子两侧的导杆，导杆滑动连接在基板上；第二推动机构包括凸轮轴承随动器和设置于散热器的底部的坡形凸台，凸轮轴承随动器固定在导杆上，坡形凸台对应凸轮轴承随动器设置，凸轮轴承随动器与坡形凸台相接触。
在此基础上，通过将导杆滑动连接在基板上，推动导杆实现了第一推动机构沿基板所在平面进行运动，通过设置凸轮轴承随动器和坡形凸台，凸轮轴承随动器与坡形凸台相接触，当凸轮轴承随动器在坡形凸台上来回滑动时，若凸轮轴承随动器固定，则坡形凸台会沿某一方向作往复运动，可以通过限制坡形凸台，对其运动进行分解，使其沿着第一方向作往复运动。通过将凸轮轴承随动器固定在导杆上，将坡形凸台固定在散热器上，推动导杆来回运动，即可通过凸轮轴承随动器和坡形凸台带动散热器在第一方向上作往复运动。
可选地，坡形凸台为单边坡形凸台，导杆上设置有用于限制导杆的滑动距离的限位凸台，滑动距离小于或等于单边坡形凸台的坡形部分的水平长度。
在此基础上，由于单边坡形凸台相当于单向锁，即凸轮轴承随动器滑过单边坡形凸台最高点后无法再滑到单边坡形凸台的最低点，从而导致第二推动机构无法作往复运动。因此，通过设置限位凸台，限位凸台限制导杆的滑动距离小于或者等于单边坡形凸台的总水平长度，使得导杆上的凸轮轴承随动器一直处于单边坡形凸台的坡面上，以实现通过导杆的来回滑动带动单边坡形凸台作往复运动，从而实现散热器的往复运动。
可选地，坡形凸台为双边坡形凸台，导杆上设置有用于限制导杆的滑动距离的限位凸台。在此基础上，通过将坡形凸台设置为双边坡形凸台，双边坡形凸台不会限制凸轮轴承随动器在双边坡形凸台上滑动，因此无需限制导杆的具体滑动距离，但是由于测试结构的尺寸限制，导杆不能无限滑动，因此设置有限位凸台以限制导杆的滑动距离，本实施例中限位凸台限制导杆的滑动距离可以根据测试结构的具体尺寸进行设置，本处不作限定。
可选地，导杆为一体成型的“U”型导杆，导杆位于光模块笼子的外侧。在此基础上，通过将导杆设置为一体成型的“U”型导杆，有利于对散热器两侧的导杆的运动进行统一 控制，可以实现两侧的导杆同时运动且运动距离相同，从而实现散热器整体的往复运动，使得散热器的底部与光模块之间的间隙一致。
可选地，导杆的一侧的长度长于另一侧的长度，导杆的较长一侧的端部设置有手柄。通过将导杆的一侧的长度设置为长于另一侧的长度，较长的一侧方便推拉导杆，在较长的一侧的端部设置手柄，更方便控制导杆的移动。
另一种可能的设计方案中，第二推动机构包括设置于光模块笼子的两侧的第一支杆，第一支杆的一端铰接在基板上，另一端滑动连接在散热器的底部；第一推动机构包括对应第一支杆设置的第一推杆，第一推杆铰接在第一支杆的中部。
在此基础上，通过设置第一推杆作为第一推动机构，设置第一支杆作为第二推动机构，通过推拉第一推杆，带动第一支杆转动，通过第一支杆的转动，实现带动散热器沿第一方向作往复运动，整体结构简单，易于操作。
可选地，散热器的底部对应第一支杆设置有滑槽，同侧的第一支杆的另一端位于滑槽内。在此基础上，通过在散热器底部设置滑槽，将第一支杆的一端置于滑槽中，有利于实现第一支杆与散热器之间滑动连接的稳定性。
又一种可能的设计方案中，第一推动机构包括设置于光模块笼子的两侧的第二支杆和与第二支杆对应设置的第二推杆，第二支杆的一端固定连接在基板上，第二支杆的另一端与第二推杆的中部铰接；第二推动机构包括第二推杆和第三支杆，第三支杆的一端与第二推杆靠近散热器的一端固定连接，第三支杆的另一端与散热器的底部接触。
在此基础上，通过设置第二支杆、第三支杆和第二推杆，第二推杆的中部铰接在第二支杆的顶端，使得第二推杆形成一个杠杆，第二推杆与第二支杆组成第一推动机构，第二推杆与第三支杆组成第二推动机构。将第三支杆设置在第二支杆靠近散热器的一端，并使第三支杆与散热器底部接触，通过转动第二推杆的另一端，带动第三支杆作往复运动，第三支杆带动散热器沿第一方向作往复运动，以调节散热器与光模块之间的间隙。
再一种可能的设计方案中，散热器位于光模块笼子内的底部上设置有导热垫。在此基础上，通过在散热器位于光模块笼子内的底部上设置导热垫，当光模块插入到光模块笼子后，光模块与散热器相接触，便实现了在光模块与散热器的接触面间增加了导热垫，导热垫有利于增加散热器的散热能力，提升散热性能。本实施例中的底部指的是散热器与光模块相接触的面。通过设置第一推动机构和第二推动机构，在光模块插入和拔出光模块笼子的时候，使得散热器与光模块之间保持一定的间隙，也可以防止光模块在插入和拔出过程中刮掉导热垫上的导热介质，有利于实现导热垫的导热能力，提升散热性能。
第二方面，提供一种光模块测试装置，该测试装置包括作为基板的印制电路板以及如权利要求1-11任一项的光模块测试结构；光模块测试结构连接在印制电路板上。上述光模块测试装置具有与前述实施例提供的光模块测试结构相同的技术效果，此处不再赘述。

本实施例中的第一方向是指垂直于光模块与散热器1的接触面的方向；第二方向包括与光模块插入光模块笼子2的方向相同的方向，以及垂直于光模块与散热器1的接触面的方向。
参考图2，图2为本申请实施例提供的一种光模块测试结构的应用场景图。如图2所示，光模块测试结构设置在基板上，基板上可以设置一个光模块测试结构，也可以设置多个光模块测试结构，本实施例中以多个光模块测试结构为例进行说明。
该基板包括底板11和侧板12，共设置有四个光模块测试结构，四个光模块测试结构并排设置，光模块测试结构固定在底板11和侧板12，光模块测试结构中光模块笼子2的进出口靠近侧板12设置，侧板12上开设有与光模块笼子2的进出口相对应的开孔，以便于将光模块插入到光模块笼子2中。光模块测试结构中的第一推动机构可以穿过侧板12，以便于固定第一推动机构，并且方便操作。
参考图5，图5为本申请实施例提供的一种光模块测试结构的示意图之一。如图5所示，该测试结构包括：散热器1和固定在基板上的光模块笼子2，散热器1连接在光模块笼子2上。该测试结构还包括浮动支撑机构，浮动支撑机构包括第一推动机构和第二推动机构，第一推动机构一端连接在基板上，另一端与第二推动机构的一端连接，第二推动机构的另一端与散热器1活动连接，第一推动机构运动带动第二推动机构沿第一方向作往复运动，第二推动机构带动散热器1沿第一方向作往复运动。
该测试结构中，散热器1可以如图3、图4所示，散热器1用于为测试时的光模块散热，光模块笼子2用于固定光模块。如图1所示，光模块笼子2设置有顶部开口21和侧部开口22，顶部开口21用于放置散热器1，侧部开口22用于将光模块插入光模块笼子2中或者将光模块从光模块笼子2中取出。如图4所示，散热器1的底部设置有定位凸台10，定位凸台10的大小与光模块笼子2的顶部开口21的大小相匹配。在测试前，将散热器1放置在光模块笼子2上，使得散热器1底部的定位凸台10位于光模块笼子2内，然后用固定结构将散热器1和光模块笼子2进行固定。
上述的固定结构为现有技术，如可以采用卡扣，本实施例并不限定固定结构的具体形式。散热器1与光模块笼子2通过固定结构固定后，两者存在一定的位移余量，如位移余量为1-3mm，而非理论上的绝对固定。
如图5所示，在将光模块插入光模块笼子2之前，沿第二方向(图5中的水平向左方向)推动第一推动机构，第一推动机构带动第二推动机构沿第一方向(图5中的竖直向上方向)运动。如图6所示，第二推动机构将散热器1顶起，此时将光模块插入光模块笼子2中(图中未示出光模块的插入过程)，光模块与散热器1底部的定位凸台10之间保持着一定的间隙，定位凸台10不会刮伤光模块。在将光模块放入到预先设置的位置之后，沿与第二方向相反的方向(图5中的水平向右方向)推动第一推动机构，第一推动机构带动第二推动机构沿与第一方向相反的方向(图5中的竖直向下方向)运动，第二推动机构不再顶起散热器1，散热器1回到初始位置(图5所示状态)，保持与光模块之间的接触，实现散热器1对测试过程中的光模块进行散热。当需要将测试完后的光模块从光模块笼子2中取出时，沿第二方向(图5中的水平向左方向)推动第一推动机构，第一推动机构带动第二推动机构沿第一方向(图5中的竖直向上方向)运动，第二推动机构将散热器1顶起，此时将光模块从光模块笼子2中取出。在取出光模块后，可将另一个光模块插入光模块笼子2中，重复上述步骤，实现对下一个光模块的测试。
本实施例中的初始位置是指：将散热器1的定位凸台10放置于光模块笼子2中，且此时将光模块插入光模块笼子2中，可以使光模块与散热器1的定位凸台10保持接触状态时散热器1相对光模块笼子2的位置。本实施例中的活动连接包括滑动连接和铰接等连接方式，目的是实现相连的两者之间可以实现相对运动或者相对转动。
该测试机构的工作原理为：浮动机构包括第一推动机构和第二推动机构，第一推动机构的一端连接在基板上，另一端与散热器1活动连接，通过推动第一推动机构运动，带动与第一推动机构相连的第二推动机构沿第一方向作往复运动，第二推动机构带动与其相连的散热器1沿第一方向作往复运动。散热器1沿第一方向作往复运动可以实现在将光模块插入或者拔出光模块笼子2时，散热器1与光模块保持一定的间隙，实现防止散热器1刮伤光模块。
本实施例中可以将光模块笼子2和散热器1水平布置，因此第一方向可以是竖直方向。通过推动第一推动机构和第二推动机构，使得第一推动机构和第二推动机构的状态如图6所示，在此过程中，散热器1相对光模块笼子2在竖直方向上上升，此时将光模块插入到光模块笼子2中，由于散热器1被第二推动机构带动着上升，因此散热器1与光模块之间存在一定的间隙，光模块插入光模块笼子2时不会与散热器1相接触，避免了散热器1刮伤光模块。在光模块插入到预设位置时，推动第一推动机构和第二推动机构，使得第一推动机构和第二推动机构的状态如图5所示，在此过程中，散热器1相对光模块笼子2在竖直方向上下降，使得散热器1的底部与光模块相接触，实现对测试过程中的光模块进行散热。在需要将光模块从光模块笼子2拔出时，再次推动第一推动机构和第二推动机构使得散热器1相对光模块笼子2在竖直方向上上升，使得第二推动机构的状态如图6所示，实现在光模块拔出过程中与散热器1保持一定间隙，防止拔出过程中散热器1刮伤光模块。
通过设置浮动支撑机构，可以使得该测试结构在测试不同光模块时，在光模块插入和拔出光模块笼子2时，只需调节浮动支撑机构使散热器1与每个光模块之间保持间隙即可，无需根据每一个光模块组装相应的散热器1，实现了对光模块的大批量测 试。
在本申请一实施例中，散热器1沿第一方向作往复运动的运动行程为1mm-2mm。由于散热器1一般是通过固定结构连接在光模块笼子2上的，因此散热器1作往复运动的运动行程受限。通过第二推动机构将散热器1沿第一方向推动主要是为了在光模块的插入和拔出过程中与光模块保持间隙，因此将散热器1作往复运动的运动行程设置为1mm至2mm，既不会影响散热器1与光模块笼子2之间的连接，同时也使得散热器1与插拔过程中的光模块保持了间隙，避免了散热器1对光模块的刮伤。
示例的，运动行程可以为2mm。
本申请实施例中的浮动散热机构包括第一推动机构和第二推动机构，第一推动机构和第二推动机构的作用是在插入或者拔出光模块时，使散热器1与光模块之间保持间隙。因此第一推动机构的形式可以是多种多样的，可以是两个独立的机构配合所形成，也可以是一整个机构的不同部分。下面对第一推动机构和第二推动机构的具体形式进行举例说明。
示例一
本示例中，参考图5、图6，图5为本申请实施例提供的一种光模块测试结构中第一推动机构的结构示意图之一，图6为本申请实施例提供的一种光模块测试结构中第一推动机构的结构示意图之二。如图5、图6所述，第一推动机构包括设置于光模块笼子2两侧的导杆3，导杆3滑动连接在基板上；第二推动机构包括凸轮轴承随动器4和设置于散热器1的底部的坡形凸台，凸轮轴承随动器4固定在导杆3上，坡形凸台对应凸轮轴承随动器4设置，凸轮轴承随动器4与坡形凸台相接触。
需要说明的是，导杆3可以通过多种方式滑动连接在基板上，如通过滑轮的连接方式，或者通过在基板上设置滑槽的方式实现导杆3在基板上滑动。本实施例中，导杆3通过滑轨6与滑块7实现与基板滑动连接，滑轨6与滑块7为现有技术中的连接结构，参考图13，图13为本申请实施例提供的一种光模块测试结构中第一推动机构的爆炸图，如图13所示，滑块7滑动连接在滑轨6内，示例的，滑块7可以通过滚轮滑动连接在滑轨6内(图中未示出)，然后将滑轨6固定在基板上，将导杆3固定在滑块7上，固定的方式可采用螺栓连接的方式进行固定，也可以采用焊接的方式进行固定，本实施例并不限定具体的固定方式。采用滑轨6与滑块7这样的连接结构，连接简便，且滑块7与滑轨6配合稳定，便于实现第一推动机构相对基板滑动。
本申请实施例中的坡形凸台是指具有一定坡度的凸台，可供凸轮轴承随动器4在改具有坡度的凸台上滑动；凸轮轴承随动器4可以是现有技术中的标准件。由于凸轮轴承随动器4上包括作为轴的螺栓，因此，为了方便凸轮轴承随动器4与导杆3之间的连接，在导杆3上开设有与凸轮轴承随动器4上的螺栓相对应的螺孔，导杆3上的螺孔如图13所示，设置在导杆3的侧边上。凸轮轴承随动器4和导杆3可以直接通过凸轮轴承随动器4上的螺栓与导杆3上的螺孔进行连接，十分方便，当然也可以通过其它的连接方式进行连接，如采用焊接的方式进行连接。坡形凸台设置在散热器1的底部，坡形凸台可以是固定在散热器1底部，如通过焊接的方式或者螺栓连接的方式固定在散热器1底部，坡形凸台也可以是与散热器1一体成型的。
在此基础上，通过滑轨6与滑块7的连接结构将导杆3滑动连接在基板上，推动 导杆3实现了第一推动机构沿基板所在平面进行运动。通过设置凸轮轴承随动器4和坡形凸台，凸轮轴承随动器4与坡形凸台相接触，由于凸轮轴承随动器4是固定在导杆3上的，因此凸轮轴承随动器4可以随着导杆3沿基板所在的平面进行运动，但被限制其它方向的运动。当凸轮轴承随动器4在坡形凸台上来回滑动时，由于凸轮轴承随动器4被限制其它方向的运动，则在凸轮轴承随动器4在坡形凸台上来回滑动的过程中，坡形凸台会沿某一方向作往复运动。然后可以通过限制坡形凸台，对其运动进行分解，使其沿着第一方向作往复运动。或者通过设置坡形凸台的位置和坡形的角度，使得坡形凸台沿着第一方向作往复运动，从而带动散热器1沿第一方向作往复运动。通过将凸轮轴承随动器4固定在导杆3上，将坡形凸台固定在散热器1上，推动导杆3来回运动，即可通过凸轮轴承随动器4和坡形凸台带动散热器1在第一方向上作往复运动。
在本申请一实施例中，坡形凸台为单边坡形凸台51，单边坡形凸台51是指凸台只有一侧具有坡形，或者是只有一侧的坡形适宜凸轮轴承随动器4在上面滑动。例如，将具有坡形一侧的坡度小于或者等于30°定义为适宜凸轮轴承随动器4滑动，则单边坡形凸台51一侧的坡形的坡度小于或者等于30°，另一侧的坡形的坡度大于30°。
由于坡形凸台为单边坡形凸台51，单边坡形凸台51相当于“单向锁”，则凸轮轴承随动器4在单边坡形凸台51上只能由坡度较小的一侧滑向另一侧，而不能从另一侧滑向坡度较小的一侧。因此，为了使得单边坡形凸台51能作往复运动，凸轮轴承随动器4要处于坡度较小的一侧上。为了实现该目的，在导杆3上设置有用于限制导杆3的滑动距离的限位凸台8，导杆3的滑动距离小于或等于单边坡形凸台51的坡形部分的水平长度，使得导杆3上的凸轮轴承随动器4一直处于单边坡形凸台51的坡面上，以实现通过导杆3的来回滑动带动单边坡形凸台51作往复运动，从而实现散热器1的往复运动。
例如，单边坡形凸台51的形状为直角三角形，则单边坡形凸台51的坡形部分的水平长度是指直角三角形中较长直角边的长度。又例如，单边坡形凸台51的形状为直角梯形，则单边坡形凸台51的坡形部分的水平长度可以是指梯形的斜边腰在底边上的投影长度；单边坡形凸台51的坡形部分的水平长度也可以是指梯形的下底边，当单边坡形凸台51包括水平部分时，可以将单边坡形凸台51的“坡形部分”理解为广义的坡形部分，即可以将单边坡形凸台51的水平部分算入“坡形部分”内，在本示例中，即“坡形部分”包括直角梯形的斜边腰和上底边。
在本申请一实施例中，参考图7、图8，图7为本申请实施例提供的一种光模块测试结构的示意图之三，图8为本申请实施例提供的一种光模块测试结构的示意图之四。如图7、图8所示，坡形凸台为双边坡形凸台52，导杆3上设置有用于限制导杆3的滑动距离的限位凸台8。双边坡形凸台52是指凸台的两侧均具有坡形，即凸轮轴承随动器4可以从双边坡形凸台52的一侧滑到另外一侧，也可以从双边坡形凸台52的另一侧滑向一侧。但是，由于整个测试结构的尺寸限制，第一推动机构也不能无限的运动，因此，在导杆3上设置有用于限制导杆3滑动距离的限位凸台8。限位凸台8对导杆3的滑动距离的限制可以根据实际情况中双边坡形凸台52的尺寸进行设置，一般限制导杆3的滑动距离可以等于或者略大于双边坡形凸台52的总水平距离。
在将光模块插入光模块笼子2时，可以通过推动第一推动机构和第二推动机构，使得第一推动机构和第二推动机构的状态如图8所示。在光模块插入到预设位置时，推动第一推动机构和第二推动机构，使得第一推动机构和第二推动机构的状态如图7所示，也可以反向推动第一推动机构，使得凸轮轴承随动器4运动到图7中所示双边坡形凸台52的另一侧。在需要将光模块从光模块笼子2拔出时，再次推动第一推动机构和第二推动机构使得散热器1相对光模块笼子2在竖直方向上上升，使得第二推动机构的状态如图8所示，实现在光模块拔出过程中与散热器1保持一定间隙，防止拔出过程中散热器1刮伤光模块。
双边坡形凸台52的具体形状不影响本申请发明目的的实现，可以根据实际情况进行设置，本实施例对双边坡形凸台52的具体形状不作限定。例如，双边坡形凸台52可以为钝角三角形或者梯形，且坡形部分的坡度小于或者等于45°。在此种情况下，限位凸台8对导杆3的滑动距离的限制可以根据三角形的底边或者梯形的下底边进行设置。
在本申请一实施例中，参考图11、图12，图11为本申请实施例提供的一种光模块测试结构中第一推动机构的结构示意图之一，图12为本申请实施例提供的一种光模块测试结构中第一推动机构的结构示意图之二。如图11、图12所示，导杆3为一体成型的“U”型导杆3，导杆3位于光模块笼子2的外侧。在此基础上，通过将导杆3设置为一体成型的“U”型导杆3，有利于对散热器1两侧的导杆3的运动进行统一控制，即控制一侧的导杆3运动即可带动另一侧的导杆3一起运动，可以实现两侧的导杆3同时运动且运动距离相同，从而实现散热器1整体的往复运动，使得散热器1的底部与光模块之间的间隙一致。
在本申请一实施例中，导杆3的一侧的长度长于另一侧的长度，导杆3的较长一侧的端部设置有手柄9。通过将导杆3的一侧的长度设置为长于另一侧的长度，较长的一侧方便推拉导杆3。示例的，若将该测试结构固定于一固定板上，或者将该测试结构设置于一盒体内，则较长一侧的导杆3可以穿过该固定板或者该盒体，便于在盒体外或者在固定板的另一侧控制U型导杆3的滑动。在较长的一侧的端部设置手柄9，更方便控制导杆3的移动。本实施例中手柄9的具体形状可以根据实际情况进行设置，手柄9的具体形状不影响本申请发明目的的实现，因此对手柄9的具体形状不作限定。
示例的，参考图13，图13为本申请实施例提供的一种光模块测试结构中第一推动机构的爆炸图。手柄9的形状可以如图12、11所示，手柄9上设置有连接槽和连接孔，便于与导杆3相连，手柄9与导杆3之间可以通过螺纹连接的方式进行连接。
示例二
本示例中，参考图9，图9为本申请实施例提供的一种光模块测试结构的示意图之五。如图9所示，第二推动机构包括设置于光模块笼子2的两侧的第一支杆13，第一支杆13的一端铰接在基板上，另一端滑动连接在散热器1的底部；第一推动机构包括对应第一支杆13设置的第一推杆14，第一推杆14铰接在第一支杆13的中部。
第二推动机构中的第一支杆13由于一端铰接在基板上，另一端在散热器1底部滑动，因此第一支杆13在运动时作圆弧运动，由于圆弧中每一点的空间位置都不相同，当第二推动机构中的第一支杆13沿着圆弧轨迹往复运动时，会推动散热器1沿第一方 向作往复运动。第一方向根据实际情况进行确定，第一方向与光模块进入或者拔出光模块笼子2的方向垂直，目的是使得光模块在进入或者拔出光模块笼子2时，散热器1可以与光模块之间保持一定的间隙。第一推动机构中的第一推杆14主要用于带动第一支杆13作往复运动，因此，将第一推杆14连接在第一支杆13上，在第一推杆14的另一端施加推力或者拉力即可带动第一支杆13运动。由于第一支杆13在运动时作圆弧运动，为了实现第一推杆14的灵活性，可以将第一推杆14的一端铰接在第一支杆13上，这样可以实现第一推杆14的另一端运动弧度较小，便于整体的布置。
在此基础上，通过设置第一推杆14作为第一推动机构，设置第一支杆13作为第二推动机构，通过推拉第一推杆14，带动第一支杆13转动，通过第一支杆13的转动，实现带动散热器1沿第一方向作往复运动，整体结构简单，易于操作。
在本申请一实施例中，散热器1的底部对应第一支杆13设置有滑槽，同侧的第一支杆13的另一端位于滑槽内。在散热器1的底部设置滑槽，实现与第一支杆13的配合，通过设置滑槽，可以限定第一支杆13在散热器1上的滑动路径，同时可以防止第一支杆13与散热器1脱落。由于散热器1的两侧均设置有第一支杆13，因此在散热器1底部的左右两侧对应第一支杆13处均设置有滑槽，将第一支杆13的另一端放置于其对应的滑槽内。在实际应用中，本领域技术人员可以根据情况在第一支杆13的另一端设置滑轮，以增加第一支杆13与散热器1之间的滑动性。
示例三
本示例中，参考图10，图10为本申请实施例提供的一种光模块测试结构的示意图之六。如图10所示，第一推动机构包括设置于光模块笼子2的两侧的第二支杆15和与第二支杆15对应设置的第二推杆16，第二支杆15的一端固定连接在基板上，第二支杆15的另一端与第二推杆16的中部铰接；第二推动机构包括第二推杆16和第三支杆17，第三支杆17的一端与第二推杆16靠近散热器1的一端固定连接，第三支杆17的另一端与散热器1的底部接触。
本示例中，第二推杆16既是第一推动机构的组成部分，又是第二推动机构的组成部分。通过设置第二支杆15和第二推杆16，第二推杆16的中部铰接在第二支杆15的顶端，使得第二推杆16形成一个杠杆，第二支杆15的顶端为杠杆的支点，第二推杆16与第二支杆15组成第一推动机构。通过在第二推杆16靠近散热器1的一端设置第三支杆17，第二推杆16与第三支杆17组成第二推动机构。将第三支杆17设置在第二支杆15靠近散热器1的一端，并使第三支杆17与散热器1底部接触，通过转动第二推杆16的另一端，带动第三支杆17作往复运动，第三支杆17带动散热器1沿第一方向作往复运动，以调节散热器1与光模块之间的间隙。当第一方向为非竖直方向时，可能散热器1的重力在第一方向上的分力较小，散热器1无法依靠自身的重力使其恢复到与光模块相接触的位置，此时，可以将第三支杆17与散热器1底部在接触的基础上，再进行相连，以带动散热器1返回到与光模块相接触的位置。
在本申请一实施例中，散热器1位于光模块笼子2内的底部上设置有导热垫18。参考图14，图14为本申请实施例提供的一种光模块测试结构中导热垫18的结构示意图。如图14所示，在此基础上，通过在散热器1位于光模块笼子2内的底部上设置导热垫18，当光模块插入到光模块笼子2后，光模块与散热器1相接触，便实现了在光 模块与散热器1的接触面间增加了导热垫18，导热垫18有利于增加散热器1的散热能力，提升散热性能。本实施例中的底部指的是散热器1与光模块相接触的面。通过设置第一推动机构和第二推动机构，在光模块插入和拔出光模块笼子2的时候，使得散热器1与光模块之间保持一定的间隙，也可以防止光模块在插入和拔出过程中刮掉导热垫18上的导热介质，有利于实现导热垫18的导热能力，提升散热性能。
此外，由于导热垫18具有一定的厚度，因此导热垫18的厚度不能影响光模块插入和拔出光模块笼子2，导热垫18的厚度可以根据散热器1作往复运动的最大行程进行设置。例如，散热器1作往复运动的最大行程为2mm，则可以设置导热垫18的厚度为1mm或者1.5mm，导热垫18是设置在散热器1上与光模块相接触的一面上，因此当导热垫18厚度为1mm时，散热器1运动到最大行程处，将光模块插入光模块笼子2时，光模块与导热垫18之间还保持有1mm的间隙；如果将导热垫18的厚度设置为1.5mm，则光模块与导热垫18之间可以保持最多0.5mm的间隙，不会对光模块和导热垫18产生刮伤。
基于同一发明构思，本申请一实施例提供一种光模块测试装置，该测试装置包括作为基板的印制电路板以及上述任一实施例所提供的光模块测试结构，光模块测试结构连接在印制电路板上。印制电路板为现有技术，本实施例中并不限定印制电路板的具体型号结构，可以根据实际情况灵活采用适宜的印制电路板。上述光模块测试装置具有与前述实施例提供的光模块测试结构相同的技术效果，此处不再赘述。
