光通信技术在信息处理设备之间建立信息传递，光通信技术将信息加载到光上，利用光的传播实现信息的传递，加载有信息的光就是光信号。光信号在信息传输设备中传播，可以减少光功率的损耗，实现高速度、远距离、低成本的信息传递。信息处理设备能够处理的信息以电信号的形态存在，光网络终端/网关、路由器、交换机、手机、计算机、服务器、平板电脑、电视机是常见的信息处理设备，光纤及光波导是常见的信息传输设备。
信息处理设备与信息传输设备之间的光信号、电信号相互转换，是通过光模块实现的。例如，在光模块的光信号输入端和/或光信号输出端连接有光纤，在光模块的电信号输入端和/或电信号输出端连接有光网络终端；来自光纤的第一光信号传输进光模块，光模块将第一光信号转换为第一电信号，光模块将第一电信号传输进光网络终端；来自光网络终端的第二电信号传输进光模块，光模块将第二电信号转换为第二光信号，光模块将第二光信号传输进光纤。由于信息处理设备之间可以通过电信号网络相互连接，所以至少需要一类信息处理设备直接与光模块连接，并不需要所有类型的信息处理设备均直接与光模块连接，直接连接光模块的信息处理设备被称为光模块的上位机。
图1为根据本公开一些实施例提供的一种光通信系统局部架构图。如图1所示，光通信系统的局部呈现为远端信息处理设备1000、本地信息处理设备2000、上位机100、光模块200、光纤101以及网线103。
光纤101的一端向远端信息处理设备1000方向延伸，另一端接入光模块200的光接口。光信号可以在光纤101中发生全反射，光信号在全反射方向上的传播几乎可以维持原有光功率，光信号在光纤101中发生多次的全反射，将来自远端信息处理设备1000方向的光信号传输进光模块200中，或将来自光模块200的光向远端信息处理设备1000方向传播，实现远距离、功率损耗低的信息传递。
光纤101的数量可以是一根，也可以是多根(两根及以上)；光纤101与光模块200采用可插拔式的活动连接，也可采用固定连接。
上位机100具有光模块接口102，光模块接口102被配置为接入光模块200，从而使得上位机100与光模块200建立单向/双向的电信号连接；上位机100被配置为向光模块200提供数据信号，或从光模块200接收数据信号，或对光模块200的工作状态进行监测、控制。
上位机100具有对外电接口，如通用串行总线接口(Universal Serial Bus，USB)、 网线接口104，对外电接口可以接入电信号网络。示例地，网线接口104被配置为接入网线103，从而使得上位机100与网线103建立单向/双向的电信号连接。
光网络终端(Optical Network Unit，ONU)、光线路终端(Optical Line Terminal，OLT)、光网络设备(Optical Network Terminal，ONT)及数据中心服务器为常见的上位机。
网线103的一端连接本地信息处理设备2000，另一端连接上位机100，网线103在本地信息处理设备2000与上位机100之间建立电信号连接。
示例地，本地信息处理设备2000发出的第三电信号通过网线103传入上位机100，上位机100基于第三电信号生成第二电信号，来自上位机100的第二电信号传输进光模块200，光模块200将第二电信号转换为第二光信号，光模块200将第二光信号传输进光纤101，第二光信号在光纤101中传向远端信息处理设备1000。
示例地，来自远端信息处理设备1000方向的第一光信号通过光纤101传播，来自光纤101的第一光信号传输进光模块200，光模块200将第一光信号转换为第一电信号，光模块200将第一电信号传输进上位机100，上位机100基于第一电信号生成第四电信号，上位机100将第四电信号传入本地信息处理设备2000。
光模块是实现光信号与电信号相互转换的工具，在上述光信号与电信号的转换过程中，信息并未发生变化，信息的编解码方式可以发生变化。

光模块200插入上位机100的笼子106中，由笼子106固定光模块200，光模块200产生的热量传导给笼子106，然后通过散热器107进行扩散。光模块200插入笼子106中后，光模块200的电接口与笼子106内部的电连接器连接。
图3为根据本公开一些实施例提供的一种光模块的结构图。图4为根据本公开一些实施例提供的一种光模块的分解图。如图3和图4所示，光模块200包括壳体、设置于壳体内的电路板201及光接收部件和/或光发射部件。
壳体包括上壳体300和下壳体400，上壳体300盖合在下壳体400上，以形成具有两个开口的壳体；壳体的外轮廓一般呈现方形体。
在本公开的一些实施例中，下壳体400包括底板以及位于底板两侧、与底板垂直设置的两个下侧板；上壳体300包括盖板，盖板盖合在下壳体400的两个下侧板上，以形成上述壳体。
在一些实施例中，下壳体400包括底板以及位于底板两侧、与底板垂直设置的两个下侧板；上壳体300包括盖板以及位于盖板两侧、并与盖板垂直设置的两个上侧板，由两个上侧板与两个下侧板结合，以实现上壳体300盖合在下壳体400上。
上述两个开口分别为第一开口204和第二开口205，第一开口204和第二开口205的连线所在的方向可以与光模块200的长度方向一致，也可以与光模块200的长度方向不一 致。例如，第一开口204位于光模块200的端部(图3的右端)，第二开口205也位于光模块200的端部(图3的左端)。或者，第一开口204位于光模块200的端部，而第二开口205则位于光模块200的侧部。
第一开口204为电口，电路板201的金手指从电口伸出，插入上位机(例如，光网络终端)中。第二开口205为光口，被配置为接入外部光纤101，以使外部光纤101连接光模块200内部的光接收部件和/或光发射部件。
采用上壳体300、下壳体400结合的装配方式，便于将电路板201、光接收部件和/或光发射部件等器件安装到壳体中，由上壳体300和下壳体400对这些器件形成封装保护。此外，在装配电路板201、光发射部件及光接收部件等器件时，通过采用上壳体300、下壳体400结合的装配方式，便于这些器件的定位部件、散热部件以及电磁屏蔽部件的部署，有利于自动化地实施生产。
在一些实施例中，上壳体300及下壳体400一般采用金属材料制成，利于实现电磁屏蔽以及散热。
在一些实施例中，光模块200还包括位于其壳体外部的解锁部件，解锁部件被配置为实现光模块200与上位机之间的固定连接，或解除光模块200与上位机之间的固定连接。
示例地，解锁部件500位于下壳体400的两个下侧板的外壁上，具有与上位机笼子(例如，光网络终端的笼子106)匹配的卡合部件。当光模块200插入上位机的笼子里，由解锁部件的卡合部件将光模块200固定在上位机的笼子里；拉动解锁部件时，解锁部件的卡合部件随之移动，进而改变卡合部件与上位机的连接关系，以解除光模块200与上位机的卡合关系，从而可以将光模块200从上位机的笼子里抽出。
电路板201包括电路走线、电子元件及芯片，通过电路走线将电子元件和芯片按照电路设计连接在一起，以实现供电、电信号传输及接地等功能。电子元件例如包括电容、电阻、三极管及金属氧化物半导体场效应管(Metal-Oxide-Semiconductor Field-Effect Transistor，MOSFET)。芯片例如包括微控制单元(Microcontroller Unit，MCU)、激光驱动芯片、限幅放大器、时钟数据恢复(Clock and Data Recovery，CDR)芯片、电源管理芯片及数字信号处理(Digital Signal Processing，DSP)芯片。
电路板201一般为硬性电路板，硬性电路板由于其相对坚硬的材质，还可以实现承载作用，如硬性电路板可以平稳地承载上述电子元件和芯片；当光接收部件和/或光发射部件位于电路板上时，硬性电路板也可以提供平稳地承载；硬性电路板还可以插入上位机笼子中的电连接器中。
电路板201还包括形成在其端部表面的金手指，金手指由相互独立的多个引脚组成。电路板201插入笼子106中，由金手指与笼子106内的电连接器导通连接。金手指可以仅设置在电路板201一侧的表面(例如图4所示的上表面)，也可以设置在电路板201上下两侧的表面，以适应引脚数量需求大的场合。金手指被配置为与上位机建立电连接，以实现供电、接地、I2C信号传递、数据信号传递等。
当然，部分光模块中也会使用柔性电路板。柔性电路板一般与硬性电路板配合使用，以作为硬性电路板的补充。例如，硬性电路板与光接收部件和/或光发射部件之间可以采用柔性电路板连接。
光发射部件和/或光接收部件位于电路板201的远离金手指的一侧；在一些实施例 中，光发射部件及光接收部件分别与电路板201物理分离，然后分别通过相应的柔性电路板或电连接件与电路板201电连接；在一些实施例中，光发射部件和/或光接收部件可以直接设置在电路板201上，可以设置在电路板的表面，也可以设置在电路板的侧边。
图5为根据本公开一些实施例提供的一种下壳体的结构示意图一；图6为根据本公开一些实施例提供的一种下壳体的结构示意图二。图5和图6从不同的角度对下壳体进行展示。
如图5和图6所示，本公开的一些实施例提供的下壳体400包括底板410、第一下侧板420和第二下侧板430，其中，第一下侧板420位于底板410的一侧，第二下侧板430位于底板410的另一侧。第一下侧板420的头部向光模块内部凹陷，第二下侧板430的头部向光模块内部凹陷，因此下壳体400头部的宽度相较下壳体400的其他部位稍小。下壳体的宽度为第一下侧板420的内壁和第二下侧板430的内壁之间的距离。
如图5所示，第一下侧板420的头部具有第一弹簧槽421，第一弹簧槽421内设置第一弹性件，第一下侧板420的中部具有第一凹槽422和第一锁止槽423。第一弹簧槽421、第一凹槽422和第一锁止槽423的结构设置便于解锁部件500的安装。第一凹槽422被配置为配合连接解锁部件500的尾部，光模块解锁过程中，解锁部件500的尾部可在第一凹槽422移动；第一锁止槽423被配置为解锁部件500的尾部的限位，以防止光模块解锁以及锁止过程中解锁部件500移位超限。第一下侧板420的头部靠近光模块的光口，尾部远离光模块的光口。第一弹性件受力后沿光模块长度方向伸缩。
其中，第一弹性件可以是弹簧。
第一凹槽422与第一锁止槽423之间具有第一卡凸425，第一卡凸425向第一下侧板420的外侧凸起。第一凹槽422的另一侧具有第一限位凸起424，第一限位凸起向第一下侧板420的外侧凸起。第一限位凸起424可以是圆柱形结构，可以是其它形状的结构。
如图6所示，第二下侧板430的头部具有第二弹簧槽431，第二弹簧槽431内设置第二弹性件，第二下侧板430的中部具有第二凹槽432和第二锁止槽433。第二弹簧槽431、第二凹槽432和第二锁止槽433的设置更加便于解锁部件500的安装。第二凹槽432配合连接解锁部件500的尾部，在光模块解锁过程中，解锁部件500的尾部可在第二凹槽432内移动。第二锁止槽433配合解锁部件500的尾部的限位，防止在解锁以及锁止过程中解锁部件500移位超限。第二凹槽432配合第一凹槽422、第二锁止槽433配合第一锁止槽423，使解锁部件500的使用更加可靠。
第二凹槽432与第二锁止槽433之间具有第二卡凸435，第二卡凸435相对于第二凹槽432向第二下侧板的外侧凸起。第二凹槽的另一侧具有第二限位凸起434，第二限位凸起434向第二下侧板的外侧凸起。第二弹性件受力后沿光模块长度方向伸缩。
其中，第二弹性件可以是弹簧。
为方便本公开实施例提供光模块的安装以及使用可靠性，本公开实施例提供了一种解锁部件。图7为根据本公开一些实施例提供的一种解锁部件的第一角度结构图。图8为根据本公开一些实施例提供的一种解锁部件的第二角度结构示意图。图7和图 8示出了本公开实施例提供的一种解锁部件的详细结构。
如图7和图8所示，本公开实施例提供的解锁部件500包括手柄510和解锁器。解锁器连接下壳体400，手柄510的一端连接解锁器的一端。手柄510可方便拖动解锁部件500，拖动手柄510，可带动解锁器移动。为方便拖动手柄510，手柄510上具有第一连接部511，手柄510通过第一连接部511连接解锁器。解锁器的另一端具有锁止卡勾，锁止卡勾与笼子卡扣连接，实现光模块与笼子的机械连接。
本公开的一些实施例中，解锁器包括第一解锁部521和第二解锁部522。第一解锁部521的一端连接手柄510，第一解锁部521的另一端与第一下侧板420配合连接。拖动手柄510时，第一解锁部521可沿第一下侧板420延伸方向移动。第二解锁部522的一端连接手柄，第二解锁部522的另一端与第二下侧板430配合连接。拖动手柄510时，第二解锁部522可沿第一下侧板420延伸方向移动。第一解锁部521的一端和第二解锁部522的一端均与第一连接部511连接。拖动手柄510时，手柄510通过第一连接部511带动第一解锁部521，以使第一解锁部521在第一下侧板420上移动；以及手柄510通过第一连接部511带动第二解锁部522，以使第二解锁部522在第二下侧板430上移动。
在本公开实施例中，第一解锁部521的另一端具有第一锁止卡勾524，第一锁止卡勾524实现第一解锁部521与笼子锁止；第二解锁部522的一端也设置第二锁止卡勾525，第二锁止卡勾525实现第二解锁部522与笼子锁止。第一锁止卡勾524与第二锁止卡勾525结合实现光模块与笼子的锁止，保证光模块与笼子的锁止牢固性。在进行光模块与笼子解锁过程中，第一锁止卡勾524与第二锁止卡勾525使解锁部件500受力均衡，便于保证解锁部件500的使用寿命。
第一解锁部521具有第一限位孔528，第一限位凸起424位于第一限位孔528内部。第一限位孔528的开孔面积大于第一限位凸起424的横截面积。第一限位凸起424的截面可以是圆形，也可以是椭圆形、长方形。
第二解锁部522具有第二限位孔529，第二限位凸起434位于第二限位孔529内部，第二限位孔529的开孔面积大于第二限位凸起434的横截面积。第二限位凸起434在第二限位孔529范围内滑动。
第一限位孔528对第一限位凸起424形成位置限定，第一限位凸起424在第一限位孔528范围内进行滑动。第二限位孔529对第二限位凸起434形成位置限定，第二限位凸起434在第二限位孔529范围内进行滑动。
本公开实施例提供的解锁部件500还包括桥接部523，桥接部523的一端连接第一解锁部521的一端、桥接部523的另一端连接第二解锁部522的一端。桥接部523有助于提升手柄510与第一解锁部521以及第二解锁部522的连接牢固性。第一连接部511与桥接部523连接。
在本公开实施例中，手柄510可为注塑成型件，解锁器可为钣金件，桥接部523可与第一解锁部521、第二解锁部522一体成型。为方便手柄510与桥接部523连接以及保证手柄510与桥接部523连接的牢固性，第一连接部511注塑包裹桥接部523。在第一解锁部521和第二解锁部522的头部还包括若干通孔，便于手柄510注塑成型过程中紧密连接第一解锁部521和第二解锁部522。
为了方便解锁部件在光模块外壳上解锁活动，光模块的外壳与解锁部件内壁之间存在一定的缝隙。光模块插入笼子使用时，笼子内侧的簧片压紧光模块，此时笼子的簧片压紧的只是光模块的外表面，解锁部件并没有压紧到光模块外壳上，此时，解锁部件内侧与光模块外壳之间的间隙就成为电磁波的泄漏路径。
为了减少电磁波泄露，在解锁部件的内设设置簧片，簧片位于解锁部件与光模块壳体之间。第一解锁部521具有第一簧片600，第一簧片600位于第一解锁部521的内壁。第一簧片600呈弧形，弧形簧片的中心区域向远离第一解锁部521的方向凸起。第一限位孔528的一侧具有第一锁止卡勾524，另一侧设置第一簧片600。第一簧片600的顶端与第一解锁部521的内壁的距离为0.3mm-1.5mm。如果第一簧片600的顶端到第一解锁部521的内壁的距离小于0.3mm，则解锁器与光模块外壳之间将存在缝隙，解锁器与光模块外壳接触不紧密；如果第一簧片600的顶端到第一解锁部521的内壁的距离大于1.5mm，则导致组装后第一解锁部521的外壁凸出于光模块的外壳，导致装配不良、解锁不畅、解锁部件回弹卡顿或解锁部件不能自动归位。
第一解锁部521的一端具有第一解锁止回部5211，第一解锁止回部5211位于第一锁止卡勾524的左侧，第一解锁止回部5211的宽度大于第一解锁部521的宽度。第一锁止槽423的宽度小于第一凹槽422的宽度，因此在第一锁止槽423与第一凹槽422之间具有第一台阶面4231，第一解锁止回部5211的端部为第一簧片基准面5212，第一簧片基准面抵靠于第一台阶面处，实现第一解锁部521与第一下侧板420的限位。
第一簧片600为金属导电材质，可以是SUS301高回弹不锈钢，第一簧片600的厚度为0.03～0.07mm。第一簧片600的厚度可以为0.05mm。第一簧片600还可以是玻铜或电镀镍材质，以避免因外部环境腐蚀生锈。
第一簧片600的凸起最高处与第一解锁部521件的基准面之间的长度大于或等于8.9mm，且第一簧片600的凸起最高处与第一解锁部521件的基准面之间的长度小于或等于12.7mm，使得弧形区域与光模块外部的笼子密切接触，以防止电磁波泄露，提高光模块的电磁屏蔽效果。
第一簧片600的宽度等于或小于第一解锁部521的宽度，使得弧形区域与光模块外部的笼子密切接触，以防止电磁波泄露，提高光模块的电磁屏蔽效果。
图9为根据本公开一些实施例提供的一种第一簧片的第一角度的结构示意图。图10为根据本公开一些实施例提供的一种解锁部件的第二角度结构图。图11为根据本公开一些实施例提供的一种解锁部件与下壳体的第一角度结构图。图12为根据本公开一些实施例提供的一种解锁部件与下壳体的第二角度结构示意图。结合图9、图10、图11和图12所示，第一簧片600包括第一导向部601、第一凸起部602和第二导向部603，第一导向部601抵靠于第一解锁部521的内壁，第一导向部601与第一解锁部521的内壁固定连接，第二导向部603抵靠于第一解锁部521的内壁，第二导向部603与第一解锁部521内壁活动连接。第一凸起部602设置于第一导向部601与第二导向部603之间，呈弧形向第一解锁部521的对侧凸起。第一导向部601的端部与第一解锁部521的内壁固定连接，第二导向部603与第一解锁部521活动连接。第一簧片600的一端与第一解锁部521固定连接，另一端不固定，使得在装配使用过程中，第一簧片600受到压力时，未固定的一端向固定侧的对端移动，释放压力。
在本公开的一些实施例中，第二导向部603与第一解锁部521活动连接，可以是第二导向部603抵靠于第一解锁部521的内壁，但第二导向部603不与第一解锁部521通过连接件连接规定；也可以是第二导向部603与第一解锁部521的内壁通过某一连接件连接，但第二导向部603与第一解锁部521之间可在一定范围内产生位置改变；也可以是第二导向部603与第一解锁部521的内壁之间存在一定的缝隙。
第一导向部601的面积大于第二导向部603的面积，以增加第一簧片600与第一解锁部521的连接面积，避免因第一解锁部521与第一下侧板420之间的摩擦力过大，而出现第一簧片600与第一解锁部521脱离的情况。
沿第一导向部601向第一凸起部602方向，第一簧片600逐步向远离第一解锁部521内壁的方向凸起，第一凸起部602的长度中心位置为第一凸起部602距离第一解锁部521内壁最大的部位，也是解锁部件与下壳体组装后第一凸起部602距离第一下侧板420最近的位置。沿第二导向部603向第一凸起部602方向，第一簧片600逐步向远离第一解锁部521内壁的方向凸起，第一凸起部602的长度中心位置为第一凸起部602距离第一解锁部521内壁最大的部位，也是解锁部件与下壳体组装后第一凸起部602距离第一下侧板420最近的位置。
第二导向部603的一侧抵靠于第一解锁部521的内部，但不与第一解锁部521固定。当解锁部件与下壳体连接时，第一簧片600填充于第一解锁部521与第一下侧板420之间，第一簧片600受到压力，第一凸起部602的凸起距离变小，第一凸起部602受挤压向第二导向部603的方向延伸。
第二导向部603的一侧抵靠于第一解锁部521的内壁，使得在解锁部件与下壳体发生相对运动时，第一凸起部602沿靠近第一解锁部521的位置进行延伸。
在本公开的一些实施例中，第二导向部603也可以与第一解锁部521固定连接。第二导向部603与第一解锁部521固定的方式可以是焊接也可以是胶接。
为了释放压力，减少第一解锁部521与第一下侧板420之间的摩擦，第一凸起部602具有开口槽6021，使得第一凸起部602在受力时易于变形释放压力。开口槽的开口延伸方向为光模块的长度方向，开口槽6021的开口延伸方向与解锁部件在壳体的滑动方向一致。开口槽6021使得第一凸起部602的刚性减弱，以使第一凸起部602在受到压力的情况下便于发生形变，使第一簧片填充于第一解锁部521与第一下侧板420之间的缝隙内，避免第一解锁部521向外部凸起而发生形变。
第一凸起部602可具有一个开口槽6021，也可设置2个开口槽或2个以上的开口槽。
为减少第一凸起部602受到压力后，第一凸起部602对第一解锁部521的压力，第一导向部601与第一凸起部602之间具有第一过渡部604，第一过渡部倾斜于第一解锁部521设置。第一过渡部604的一端与第一导向部601连接，第一过渡部604的另一端与第一凸起部602连接。沿第一导向部601向第一凸起部602方向，第一过渡部604逐步远离第一解锁部521的内壁。第一过渡部604倾斜于第一解锁部521设置，将第一凸起部602受到的挤压力分解为垂直于第一解锁部521方向和平行于第一解锁部521方向的两个分量，减少第一导向部601受到的压力，同时减少了第一导向部601与第一解锁部521之间的摩擦力，以避免第一解锁部521与第一下侧板420之间的连 接脱落。
为减少第一凸起部602受到压力后，第一凸起部602对第一解锁部521的压力，第二导向部603与第一凸起部602之间设置第二过渡部605，第二过渡部605倾斜于第一解锁部521设置。第二过渡部605的一端与第二导向部603连接，第二过渡部605的另一端与第一凸起部602连接。沿第二导向部603向第一凸起部602方向，第二过渡部逐步远离第一解锁部521的内壁。第二过渡部605的一端倾斜于第一解锁部521设置，将第一凸起部602受到的挤压力分解为垂直于第一解锁部521方向和平行于第一解锁部521方向的两个分量，减少第一导向部601受到的压力，同时减少了第一导向部601与第一解锁部521之间的摩擦力，以避免第一解锁部521与第一下侧板420之间的连接脱落。
开口槽可设置为仅贯穿第一凸起部602，也可设置为开口槽贯穿第一过渡部604、第一凸起部602和第二过渡部605。开口槽使得第一凸起部602的刚性减弱，使得第一凸起部602在受到压力的情况下便于发生形变，使第一簧片填充于第一解锁部521与第一下侧板420之间的缝隙内，而避免第一解锁部521向外部凸起而发生形变。
第一簧片600的中心的距离第一簧片基准面的长度为8.9mm-12.7mm，第一簧片600的中心为第一凸起部602的中心。第一簧片600的中心的距离第一簧片基准面的长度为10.9mm。
第一簧片的顶端与第一解锁部的内壁的距离以第一凸起部与第一解锁部的内壁的最大距离进行表示。
第二解锁部522具有第二簧片700，第二簧片700位于第二解锁部522的内壁，第二簧片700呈弧形，弧形簧片的中心区域向第二解锁部522的内壁凸起。第二限位孔529的一侧具有锁止卡勾，第二限位孔529的另一侧设置第二簧片700。第二簧片700的顶端与第二解锁部的内壁的距离大于或等于0.3mm，且第二簧片700的顶端与第二解锁部的内壁的距离小于或等于1.5mm。如果第二簧片700的顶端到第二解锁部的内壁的距离小于0.3mm，则解锁部件与光模块外壳之间接触不紧密；如果第二簧片700的顶端到第二解锁部522的内壁的距离大于1.5mm，将导致组装后第二解锁部522的外壁凸出于光模块的外壳，造成装配不良、解锁不畅、解锁部件回弹卡顿或解锁部件不能自动归位。
第二解锁部522的一端具有第二解锁止回部，第二解锁止回部位于第二锁止卡勾的左侧，第二解锁止回部的宽度大于第二解锁部522的宽度。第二锁止槽的宽度小于第一凹槽的宽度。第二锁止槽与第二凹槽之间具有第二台阶面，第二解锁止回部的端部为第二簧片基准面，第二簧片基准面抵靠于第二台阶面处，以实现第二解锁部522与第二下侧板的限位。
第二簧片700为金属导电材质，第二簧片700可以是SUS301高回弹不锈钢，厚度为0.03-0.07mm。第二簧片700厚度为0.05mm。第二簧片700还可以是玻铜或电镀镍材质，以避免因外部环境腐蚀生锈。
第二簧片700的凸起最高处与第二解锁部的基准面之间的长度大于或等于8.9mm，且第二簧片700的凸起最高处与第二解锁部的基准面之间的长度小于或等于12.7mm，使得弧形区域与光模块外部的笼子密切接触，以防止电磁波泄露，提高光模块的电磁 屏蔽效果。
第二簧片700的宽度等于或小于第二解锁部的宽度，使得弧形区域与光模块外部的笼子密切接触，以防止电磁波泄露，提高光模块的电磁屏蔽效果。
第二簧片700包括第三导向部、第二凸起部和第四导向部。其中，第三导向部抵靠于第二解锁部的内壁，第三导向部与第二解锁部的内壁固定连接。第四导向部抵靠于第二解锁部的内壁，第四导向部与第二解锁部内壁活动连接。第二凸起部设置于第三导向部与第四导向部之间，呈弧形向第二下侧板方向凸起。第三导向部的端部与第二解锁部的内壁固定连接，第四导向部与第二解锁部活动连接。第二簧片700的一端与第二解锁部固定连接，另一端不固定，使得在装配使用过程中，第二簧片700受到压力时，未固定的一端向固定侧的对端移动，释放压力。
第三导向部与第二解锁部内壁固定连接方式可以是焊接，也可以是胶接；或者第三导向部与第二下侧板一体成型。
第三导向部的面积大于第四导向部的面积，以增加第二簧片700与第二解锁部的连接面积，避免因第二解锁部与第二下侧板之间的摩擦力过大而导致第二簧片700与第二解锁部脱离。
沿第三导向部向第二凸起部方向，第二簧片700逐步向凸出于第二解锁部内壁的方向凸起，第二凸起部的长度中心位置为第二凸起部距离第二解锁部内壁最大的部位，也是解锁部件与下壳体组装后第二凸起部距离第二下侧板最近的位置。沿第四导向部向第二凸起部方向，第二簧片700逐步向凸出于第二解锁部内壁的方向凸起，第二凸起部的长度中心位置为第二凸起部距离第二解锁部内壁最大的部位，也是解锁部件与下壳体组装后第二凸起部距离第二下侧板最近的位置。
第四导向部的一侧抵靠于第二解锁部的内部，但第四导向部不与第二解锁部固定。当解锁部件与下壳体连接时，第二簧片700填充于第二解锁部与第二下侧板之间，第二簧片700受到压力，第二凸起部的凸起距离变小，第二凸起部受挤压向第四导向部的方向延伸。
第二簧片700的开口槽的开口延伸方向为光模块的长度方向，开口槽的开口延伸方向与解锁部件在壳体的滑动方向一致。
第二凸起部可具有一个开口槽，也可设置2个开口槽或多个开口槽。第二簧片700的中心的距离第二簧片基准面的长度大于或等于8.9mm，第二簧片700的中心的距离第二簧片基准面的长度小于或等于12.7mm。第二簧片700的中心为第二凸起部的中心。第二簧片700的中心的距离第二簧片基准面的长度为10.9mm。
在本公开的一些实施例中，第一簧片600与第二簧片700对称设置于下壳体的两侧，可保证解锁部件受力均匀，避免解锁部件因受力不均衡产生形变，而造成解锁部件不能自动归位。
在拉动解锁部件时，解锁部件受到笼子内卡子施加的压力，第一簧片600与第二簧片700向未固定的一端延伸，以释放压力，减少了解锁部件与下壳体之间的摩擦力。安装完成后，第一簧片600位于第一解锁部521与第一下侧板420之间的缝隙内，第二簧片700位于第二解锁器与第二下侧板之间的缝隙内，有利于避免光模块电磁波泄露，提高光模块的电磁屏蔽效果。
在本公开的一些实施例中，第一簧片600和第二簧片700还可设置于光模块壳体外部，第一簧片600和第二簧片700均与光模块的下壳体固定。第一簧片600与第一下侧板420连接，而不与第一解锁部521连接，第一簧片600包括第一导向部601、第一凸起部602和第二导向部603，其中，第一导向部601与第一下侧板420固定连接，第一凸起部602呈弧形向远离第一下侧板420的区域靠近。第一凸起部602填充于第一下侧板420与第一解锁部521之间，以防止光模块内部的电磁波泄露至光模块外部，同时防止光模块外部的电磁波进入光模块内部。
第二导向部603可以与第一下侧板420固定连接，也可以不与第一下侧板420固定连接。第二导向部与第一下侧板420固定方式可以是焊接，或第二导向部与第一下侧板420一体成型。当第一簧片600受到第一解锁部521的挤压力时，第一簧片600的凸起部分产生形变，减少对第一下侧板的力。
第二簧片700与第二下侧板连接，而不与第二解锁部连接，第二簧片填充于第二下侧板与第一解锁部之间，以防止光模块内部的电磁波泄露至光模块外部，同时防止光模块外部的电磁波进入光模块内部。图13为根据本公开一些实施例提供的一种上壳体的结构图一，图14为根据本公开一些实施例提供的一种上壳体的结构图二，图13和图14示出了本公开实施例提供的一种上壳体的基本结构。
本公开实施例提供的上壳体300包括盖板310、第一上侧板320和第二上侧板330。在本实施例中，为避免解锁过程中弹簧受力由弹簧槽内弹出，第一上侧板头部设置第一镶嵌凸起321，第一镶嵌凸起321与第一下侧板上的第一缺口426位置对应。第二上侧板的头部设置第二镶嵌凸起，第二镶嵌凸起331与第二缺口436位置对应。当将上壳体300与下壳体400装配时，第一镶嵌凸起321嵌入第一缺口，第二镶嵌凸起331嵌入第二缺口，进而将第一弹性件与第二弹性件分别密封于第一弹簧槽与第二弹簧槽内部，避免弹性件受力由弹簧槽内弹出。
第一缺口与第一弹簧槽连通，第二缺口与第二弹簧槽连通。
当上壳体、下壳体装配后，第一镶嵌凸起嵌入第一缺口，第二镶嵌凸起嵌入第二缺口，进而将第一弹性件与第二弹性件分别密封于第一弹簧槽与第二弹簧槽内部，避免弹性件受力后由弹簧槽内弹出。
本公开的一些实施例中第一解锁部521的上侧边高出第一下侧板420的侧边，第二解锁部522的上侧边缘高出第二下侧板430的侧边。第一上侧板还具有有第三凹槽322和第三锁止槽323，第二上侧板还具有第四凹槽332和第四锁止槽333。第三凹槽322与第四凹槽332分别与解锁部件500连接，光模块解锁过程中解锁部件500的尾部可在第三凹槽322、第四凹槽332移动；第三锁止槽323和第四锁止槽333对解锁部件500进行限位，防止光模块解锁以及锁止过程中解锁部件500移位超限。
为方便解锁部件与壳体之间的滑动，第一解锁部521的宽度小于或等于第一凹槽与第三凹槽的宽度之和。第二解锁部的宽度小于或等于第二凹槽与第四凹槽的宽度之和。
