具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。

除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅被配置为描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。

如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
光通信技术中，使用光携带待传输的信息，并使携带有信息的光信号通过光纤或光波导等信息传输设备传输至计算机等信息处理设备，以完成信息的传输。由于光信号通过光纤或光波导中传输时具有无源传输特性，因此可以实现低成本、低损耗的信息传输。此外，光纤或光波导等信息传输设备传输的信号是光信号，而计算机等信息处理设备能够识别和处理的信号是电信号，因此为了在光纤或光波导等信息传输设备与计算机等信息处理设备之间建立信息连接，需要实现电信号与光信号的相互转换。
光模块在光纤通信技术领域中实现上述光信号与电信号的相互转换功能。光模块包括光口和电口，光模块通过光口实现与光纤或光波导等信息传输设备的光通信，通过电口实现与光网络终端(例如，光猫)之间的电连接，电连接主要被配置为实现供电、I2C信号传输、数据信号传输以及接地等；光网络终端通过网线或无线保真技术(Wi-Fi)将电信号传输给计算机等信息处理设备。
图1为根据一些实施例的一种光通信系统的连接关系图。如图1所示，光通信系统主要包括远端服务器1000、本地信息处理设备2000、光网络终端100、光模块200、光纤101及网线103。
光纤101的一端连接远端服务器1000，另一端通过光模块200与光网络终端100连接。光纤本身可支持远距离信号传输，例如数千米(6千米至8千米)的信号传输，在此基础上如果使用中继器，则理论上可以实现超长距离传输。因此在通常的光通信系统中，远端服务器1000与光网络终端100之间的距离通常可达到数千米、数十千米或数百千米。
网线103的一端连接本地信息处理设备2000，另一端连接光网络终端100。本地信息处理设备2000可以为以下设备中的任一种或几种：路由器、交换机、计算机、手机、平板电脑、电视机等。
远端服务器1000与光网络终端100之间的物理距离大于本地信息处理设备2000与光网络终端100之间的物理距离。本地信息处理设备2000与远端服务器1000的连接由光纤101与网线103完成；而光纤101与网线103之间的连接由光模块200和光网络终端100完成。
光模块200包括光口和电口。光口被配置为与光纤101连接，从而使得光模块200与光纤101建立双向的光信号连接；电口被配置为接入光网络终端100中，从而使得光模块200与光网络终端100建立双向的电信号连接。光模块200实现光信号与电信号的相互转换，从而使得光纤101与光网络终端100之间建立连接。示例地，来自光纤101的光信号由光模块200转换为电信号后输入至光网络终端100中，来自光网络终端100的电信号由光模块200转换为光信号输入至光纤101中。
光网络终端100包括大致呈长方体的壳体(housing)，以及设置在壳体上的光模块接口102和网线接口104。光模块接口102被配置为接入光模块200，从而使得光网络终端100与光模块200建立双向的电信号连接；网线接口104被配置为接入网线103，从而使得光网络终端100与网线103建立双向的电信号连接。光模块200与网线103之间通过光网络终端100建立连接。示例地，光网络终端100将来自光模块200的电信号传递给网线103，将来自网线103的信号传递给光模块200，因此光网络终端100作为光模块200的上位机，可以监控光模块200的工作。光模块200的上位机除光网络终端100之外还可以包括光线路终端(Optical Line Terminal，OLT)等。
远端服务器1000通过光纤101、光模块200、光网络终端100及网线103，与本地信息处理设备2000之间建立了双向的信号传递通道。
图2为根据一些实施例的一种光网络终端的结构图，为了清楚地显示光模块200与光网络终端100的连接关系，图2仅示出了光网络终端100的与光模块200相关的结构。如图2所示，光网络终端100中还包括设置于壳体内的PCB电路板105，设置在PCB电路板105的表面的笼子106，以及设置在笼子106内部的电连接器。电连接器被配置为接入光模块200的电口；散热器107具有增大散热面积的翅片等凸起部。
光模块200插入光网络终端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的电口与笼子106内部的电连接器连接，从而光模块200与光网络终端100建立双向的电信号连接。此外，光模块200的光口与光纤101连接，从而光模块200与光纤101 建立双向的电信号连接。
图3为根据一些实施例的一种光模块的结构图，图4为根据一些实施例的一种光模块的分解图。如图3和图4所示，光模块200包括上壳体201、下壳体202、解锁部件203、电路板300、光引擎400与光口托架500。
壳体包括上壳体201和下壳体202，上壳体201盖合在下壳体202上，以形成具有两个开口204和205的上述壳体；壳体的外轮廓一般呈现方形体。
在本公开一些实施例中，下壳体202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201包括盖板，以及位于盖板两侧与盖板垂直设置的两个上侧板，由两个侧壁与两个侧板结合，以实现上壳体201盖合在下壳体202上。
两个开口204和205的连线所在方向可以与光模块200的长度方向一致，也可以与光模块200的长度方向不一致。示例地，开口204位于光模块200的端部(图3的右端)，开口205也位于光模块200的端部(图3的左端)。或者，开口204位于光模块200的端部，而开口205则位于光模块200的侧部。开口204为电口，电路板300的金手指从电口204伸出，插入上位机(如光网络终端100)中；开口205为光口，配置为接入外部的光纤101，以使光纤101连接光模块200的内部。
采用上壳体201、下壳体202结合的装配方式，便于将电路板300等器件安装到壳体中，由上壳体201、下壳体202可以对这些器件形成封装保护。此外，在装配电路板300等器件时，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，有利于自动化的实施生产。
在一些实施例中，上壳体201及下壳体202一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壁的解锁部件203，解锁部件203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203位于下壳体202的两个下侧板的外壁，包括与上位机的笼子(例如，光网络终端100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203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203时，解锁部件203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300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。电子元件例如可以包括电容、电阻、三极管、金属氧化物半导体场效应管(Metal-Oxide-Semiconductor Field-Effect Transistor，MOSFET)。芯片例如可以包括微控制单元(Microcontroller Unit，MCU)、限幅放大器(Limiting Amplifier)、时钟数据恢复芯片(Clock and Data Recovery，CDR)、电源管理芯片、数字信号处理(Digital Signal Processing，DSP)芯片。
电路板300一般为硬性电路板。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的承载芯片；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300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300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300一侧的表面(例如图4所示的上表面)，也可以设置在电路板300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、数据信号传递等功能。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。
光引擎400可通过内部光纤与光纤适配器的一端连接，光纤适配器的另一端插在光口托架500内固定。由于内部光纤不能弯折，且连接光纤适配器与光引擎的内部光纤尺寸不好把握，导致光纤适配器通过内部光纤连接光引擎后，光纤适配器的另一端插入光口托架500时存在偏差，使得光纤适配器安装较复杂。
光引擎400也可与光纤适配器的一端硬连接，即光引擎的端面与光纤适配器的一端直接接触连接，光纤适配器的另一端插入光口托架500内固定。当光引擎存在安装公差时，导致 与光引擎硬连接的光纤适配器的另一端插入光口托架500时存在偏差，使得光纤适配器安装较复杂。
为了解决上述问题，本公开将光模块中下壳体202与光口托架500相分离，将光纤适配器通过内部光纤与光引擎连接，或光纤适配器与光引擎硬连接后，再将光口托架500安装至下壳体202上，以消除光纤适配器、光引擎的安装公差。
图5为根据一些实施例的一种光模块中电路板、光引擎、光口托架与光口塞的装配示意图；图6为根据一些实施例的一种光模块中电路板、光引擎、光口托架与光口塞的分解示意图。如图5、图6所示，本公开实施例提供的光模块中，下壳体202与光口托架500相分离，将光发射次模块、光接收次模块等光引擎安装至电路板300上后，将光引擎与第一光纤适配器700进行硬连接，第一光纤适配器700插入光口托架500内，再将光口托架500安装至上壳体201的一端，然后将下壳体202盖合于上壳体201上，使得光口托架500位于上壳体201与下壳体202形成的光接口处。本公开中，光口托架500在安装至上壳体201时能够降低光引擎的安装公差，工序简单，不需增加物料成本，且长期可靠。
第一光纤适配器700位于上壳体201与下壳体202形成的光接口处，是光模块200与光模块200外部光纤实现连接的连接件；此外，为了与外部光纤实现连接，往往还需要在上壳体201、下壳体202、光接口处设置匹配的结构。光纤适配器一般具有标准形状及尺寸，便于外部光纤连接器/插头插入，其内部具有多个光纤对接口，包括传出光信号的接口及传入光信号的接口。常见的光纤连接器/插头为MT型光纤连接器，如MPO(Multi-fiber Push On，光纤跳线连接器)。通过光纤连接器插入光模块的光纤适配器，使得光模块内部的光信号可以传入外部光纤中，使得光模块外部的光信号可以传入光模块内部。
光模块使用时，可将外部光纤通过光口托架500与第一光纤适配器700连接，以实现光的发射或接收；当光模块暂停使用时，可将光口塞600插入光口托架500内，以防止灰尘由光口托架500的光口进入光模块内部。
图7为根据一些实施例的一种光模块中上壳体、下壳体与光口托架的局部装配示意图。如图7所示，上壳体201朝向光口托架500的一端对称设置有第一限位件2011，该第一限位件2011突出于上壳体201的左侧面；光口托架500朝向上壳体201的侧面与上壳体201压合连接，上壳体201压合于光口托架500上时，上壳体201上的第一限位件2011与光口托架500相对的两侧面相抵接，且第一限位件2011与光口托架500相对的两侧面通过胶水粘接，以将光口托架500固定安装于上壳体201。
下壳体202朝向光口托架500的一端对称设置有第二限位件2022，光口托架500相对的两侧面上分别设置有限位凸台5310，该限位凸台5310朝向光引擎400的侧面与第二限位件2022相抵接，以对光口托架500进行左右方向的限位；该限位凸台5310朝向下壳体202的侧面与下壳体202的底面相抵接，以对光口托架500进行支撑。即光口托架500由左向右移动，直至光口托架500侧面上的限位凸台5310与下壳体202上的第二限位件2022相接触。
在本公开的一些实施例中，光口托架500通过上壳体201上的第一限位件2011进行前后方向的限位，并通过第一限位件2011与光口托架500相粘接，以将光口托架500固定在上壳体201上；再通过下壳体202上的第二限位件2022进行左右方向的限位，以方便将下壳体202盖合于上壳体201与光口托架500上。
图8为根据一些实施例的一种光模块中光口托架的结构示意图；图9为根据一些实施例的一种光模块中光口托架的另一角度结构示意图。如图8、图9所示，光口托架500包括第一侧面510、第二侧面520、第三侧面530、第四侧面540、第五侧面550与第六侧面560，第一侧面510朝向光引擎400，第二侧面520与第一侧面510相对设置；第三侧面530与第四侧面540相对设置，且第三侧面530分别与第一侧面510、第二侧面520相连接；第五侧面550与第六侧面560均朝向上壳体201，且第六侧面560凹陷于第五侧面550。即第一侧面510为光口托架500的右侧面，第二侧面520为光口托架500的左侧面，第三侧面530为光口托架500的后侧面，第四侧面540为光口托架500的前侧面，第五侧面550与第六侧面560均为光口托架500的上侧面，且第五侧面550距下壳体202的距离大于第六侧面560距下壳体202的距离。
光口托架500的第一侧面510上设置有安装孔5110，第二侧面520上设置有插槽5210， 插槽5210与安装孔5110相连通，第一光纤适配器700通过安装孔5110插入插槽5210内，使得第一光纤适配器700插入光口托架500内。光口托架500内的插槽5210开口，使得外部光纤可通过插槽5210插入光口托架500内。
图10为根据一些实施例的一种光模块中上壳体的结构示意图；图11为根据一些实施例的一种光模块中上壳体、光引擎、光纤适配器与光口托架的局部装配示意图。如图10、图11所示，上壳体201上设置的第一限位件2011突出于上壳体201的左侧端面2013，其由上壳体201的左侧端面2013沿着左右方向延伸。将上壳体201与光口托架500固定连接时，光口托架500置于两个第一限位件2011之间，两个第一限位件2011相对的侧面与光口托架500的第三侧面530、第四侧面540相抵接，以通过第一限位件2011对光口托架500进行前后方向的限位；第一限位件2011的侧面与光口托架500的第三侧面530、第四侧面540相接触后，向侧面之间的间隙内注入胶水，通过胶水粘接第一限位件2011的侧面与光口托架500的第三侧面530、第四侧面540，从而将光口托架500固定于上壳体201上。
光口托架500还包括第七侧面570，该第七侧面570与第五侧面550、第六侧面560相连接，如此第七侧面570与第一侧面510相平行。上壳体201与光口托架500的上侧面压合连接时，上壳体201的内底面与光口托架500的第六侧面560相抵接，上壳体201的左侧端面2013与光口托架500的第七侧面570相抵接，使得光口托架500的第五侧面550与上壳体201的上顶面相平齐。
在本公开的一些实施例中，首先将光口托架500置于上壳体201的两个第一限位件2011之间，然后由左至右移动光口托架500，使得光口托架500的第三侧面530、第四侧面540与两个第一限位件2011的内侧面相接触；然后继续向右移动光口托架500，直至光口托架500的第七侧面570与上壳体201的左侧端面2013相抵接；最后在光口托架500与第一限位件2011的接触面之间注入胶水，通过胶水将光口托架500固定在上壳体201上。
第一限位件2011背向第三侧面530的一侧设置有凹槽2014，该凹槽2014由第一限位件2011的后侧面向其前侧面方向延伸，且凹槽2014前后方向的尺寸小于第一限位件2011前后方向的尺寸。该凹槽2014左右方向的尺寸略小于第一限位件2011前后方向的尺寸，解锁部件203的弹簧置于该凹槽2014内，且弹簧的两端与凹槽2014相对的侧壁相抵接。
解锁部件203的两个解锁手柄上均设置有弹片2031，该弹片2031相对设置；凹槽2014朝向下壳体202的侧壁上设有向下的开口，将解锁部件203装配至上壳体201上时，解锁手柄上的弹片2031通过向下的开口嵌入上壳体201的凹槽2014内，并与凹槽2014内的弹簧相接触。解锁部件203左右移动时，弹片2031在凹槽2014内左右移动，带动弹簧拉伸或压缩，从而实现光模块与上位机之间的固定连接，或解除光模块与上位机之间的固定连接。
在本公开的一些实施例中，光口托架500的第三侧面530上设置有限位凸台5310，该限位凸台5310沿着前后方向向远离第三侧面530的方向延伸，使得限位凸台5310突出于第三侧面530；同理，光口托架500的第四侧面540上设置有限位凸台，该限位凸台沿着前后方向向远离第四侧面540的方向延伸，使得该限位凸台突出于第四侧面540。

该第二限位件2022朝向光口托架500的侧面为平面，如此下壳体202盖合于光口托架500上时，第二限位件2022朝向光口托架500的侧面抵住光口托架500上的限位凸台，以对下壳体202进行左右方向的定位。两个第二限位件2022相对的侧面也为平面，如此光口托架500插入下壳体202后，两个第二限位件2022相对的侧面可与光口托架500的第三侧面530、第四侧面540相抵接。
两个第二限位件2022相对的侧面也可与光口托架500的第三侧面530、第四侧面540之间存在间隙，以方便光口托架500插入下壳体202内。

图14为根据一些实施例的一种光模块中下壳体、光引擎、光纤适配器与光口托架的局部装配示意图。如图14所示，下壳体202盖合于光口托架500上时，将光口托架500置于下壳体202的两个第二限位件2022之间，使得光口托架500上限位凸台朝向光引擎400的侧面与第二限位件2022背向光引擎400的侧面相对齐，光口托架500的第一侧面510与下壳体202上的第三限位件2024相对齐；然后将下壳体202向下移动，直至光口托架500朝向下壳体202的侧面与下壳体202的底面2021相抵接，第二限位件2022背向光引擎400的侧面与光口托架500上限位凸台朝向光引擎400的侧面相抵接，光口托架500的第一侧面510与下壳体202上的第三限位件2024相抵接。
光口托架500的第三侧面530、第四侧面540上的限位凸台朝向上壳体201的侧面为平面，下壳体202盖合于上壳体201上时，上壳体201上的第一限位件2011朝向下壳体202的侧面与限位凸台朝向上壳体201的侧面相抵接，使得第一限位件2011支撑固定下壳体202。
在本公开的某一些实施例中，上壳体201上还对称设置有限位柱2012，该限位柱2012位于上壳体201的侧壁上，其可与第一限位件2011相连接，也可独立设置于上壳体201的侧壁上。下壳体202相对的两侧壁上设置有第一限位面2023，该第一限位面2023朝向光口托架500，且该第一限位面2023前后方向的尺寸与下壳体202侧壁前后方向的尺寸一致。下壳体202盖合于上壳体201上时，上壳体201上的限位柱2012与下壳体202上的第一限位面2023相抵接，以通过限位柱2012对下壳体202进行左右方向的限位。
下壳体202相对的两侧壁上还设置有第二限位面2025，该第二限位面2025朝向上壳体201，第一限位面2023与第二限位面2025相连接，如此下壳体202盖合于上壳体201上时，上壳体201上第一限位件2011朝向下壳体202的侧面、限位柱2012朝向下壳体202的侧面均与第二限位面2025相抵接，以通过第一限位件2011与限位柱2012支撑固定下壳体202。
在本公开的某一些实施例中，首先将光引擎400安装在电路板300上，然后将第一光纤适配器700通过内部光纤与光引擎400连接，或者将第一光纤适配器700与光引擎400硬连接；然后将光口托架500置于上壳体201的两个第一限位件2011之间，移动上壳体201，使得光口托架500的第一侧面510与上壳体201的左侧端面2013相接触，光口托架500的第三侧面530、第四侧面540与上壳体201的两个第一限位件2011相抵接；然后向光口托架500与第一限位件2011的接触间隙注入胶水，通过胶水将光口托架500固定于上壳体201上；然后移动下壳体202，将下壳体202上第二限位件2022背向光引擎400的侧面与光口托架500上限位凸台朝向光引擎400的侧面相对齐，将下壳体202上的第三限位件2024与光口托架500的第一侧面510相对齐，移动下壳体202，直至下壳体202的底面2021与光口托架500朝向下壳体202的侧面相接触，上壳体201上第一限位件2011朝向下壳体202的侧面与下壳体202上第二限位件2022朝向上壳体201的侧面相接触，上壳体201上的限位柱2012与下壳体202上的第一限位面2023、第二限位面2025相接触；然后将弹簧嵌在上壳体201上第一限位件2011的凹槽2014内；然后将解锁部件203的解锁手柄套在上壳体201、下壳体202的外侧，使得解锁手柄上的弹片2031插入第一限位件2011的凹槽2014内，与弹簧相连接。经由上述安装方式，将光口托架500固定安装在上壳体201与下壳体202形成的光接口处。
本公开提供的光模块包括上壳体、下壳体、光引擎、光口托架与光纤适配器，上壳体盖合于下壳体上，并与下壳体形成容纳腔体；光引擎设置于该容纳腔体内，被配置为实现光的发射或接收；上壳体的一端对称设置有第一限位件，下壳体的一端对称设置有第二限位件；光口托架朝向上壳体的侧面与上壳体压合连接，且其相对的两侧面与第一限位件固定连接，以将光口托架固定安装于上壳体上；光口托架与第一限位件抵接的两侧面上分别设置有限位凸台，该限位凸台与第二限位件相抵接，以对下壳体进行左右方向的定位；光纤适配器的一端与光引擎连接，另一端插入光口托架内。将光引擎安装在上壳体与下壳体形成的容纳腔体 内后，将光引擎通过内部光纤与光纤适配器连接，或将光引擎与光纤适配器直接接触硬连接，由于内部光纤不能弯折，或光纤适配器硬连接时活动量小，导致光纤适配器与光引擎存在安装公差，不易将光纤适配器插入光口托架内，因此本公开将光口托架与下壳体相分离，将光口托架相对的两侧面通过胶水与上壳体上的第一限位件固定连接，如此当光引擎在容纳腔体内安装存在安装公差时，将光口托架安装至上壳体时可降低光引擎的安装公差，工序简单，解决了光引擎安装工序较复杂的问题。
图15为根据一些实施例的另一种光模块分解结构示意图，如图15所示，光发射组件400A、光接收组件500A等光引擎可通过内部光纤与光纤适配器的一端连接，光纤适配器的另一端插在光口托架500内固定。由于内部光纤不能弯折，且连接光纤适配器与光引擎的内部光纤尺寸不好把握，导致光纤适配器通过内部光纤连接光引擎后，光纤适配器的另一端插入光口托架500时存在偏差，使得光纤适配器安装较复杂。
光发射组件400A、光接收组件500A等光引擎也可与光纤适配器的一端硬连接，即光引擎的端面与光纤适配器的一端直接接触连接，光纤适配器的另一端插入光口托架500内固定。当光引擎存在安装公差时，导致与光引擎硬连接的光纤适配器的另一端插入光口托架500时存在偏差，使得光纤适配器安装较复杂。
为了解决上述问题，本公开将光模块中下壳体202与光口托架500相分离，将光纤适配器通过内部光纤与光引擎连接，或光纤适配器与光引擎硬连接后，再将光口托架500安装至下壳体202上，以消除光纤适配器、光引擎的安装公差。
图16为根据一些实施例的一种光模块中下壳体与适配器卡槽的分解示意图，图17为根据一些实施例的一种光模块中下壳体与适配器卡槽的另一角度分解示意图。如图16、图17所示，本公开实施例提供的光模块中，下壳体202与光口托架500相分离，将光发射组件400A、光接收组件500A等光引擎安装至电路板300上后，再将光口托架500安装至下壳体202的一端，且光口托架500在安装时能够吸降低光引擎的安装公差，工序简单，不需增加物料成本，且长期可靠。
在本公开的一些实施例中，下壳体202朝向光纤适配器的一端设置有安装槽2021A，该安装槽2021A相对的两侧壁2023A为下壳体202相对的两侧壁；安装槽2021A朝向光口托架500的一端设有开口，即安装槽2021A的左端面开口，该开口的尺寸与安装槽2021A相对两侧壁之间的距离一致，如此光口托架500可通过安装槽2021A的开口插入安装槽2021A内。
在本公开的一些实施例中，将光发射组件400A、光接收组件500A安装至电路板300上后，在将光口托架500安装至下壳体202的安装槽2021A内时，将光口托架500由左至右逐渐插入安装槽2021A内，使得光口托架500相对的两侧壁与安装槽2021A的两侧壁相接触，直至光口托架500安装到位。
下壳体202靠近安装槽2021A的一端设置有安装板2022A，该安装板2022A的一端与下壳体202的一侧壁相连接、另一端与下壳体202的另一侧壁相连接，从而将安装板2022A沿前后方向固定于下壳体202内。光口托架500插入安装槽2021A时，光口托架500朝向下壳体202的侧面与安装板2022A的侧面相接触，以对光口托架500进行安装限位。
在本公开的一些实施例中，将光发射组件400A、光接收组件500A安装至电路板300上后，在将光口托架500安装至下壳体202的安装槽2021A内时，将光口托架500由左至右逐渐插入安装槽2021A内，使得光口托架500相对的两侧壁与安装槽2021A的两侧壁相接触，直至光口托架500的侧面与安装板2022A相抵接，然后通过胶水固定光口托架500与安装槽2021A相接触的侧壁，从而实现光口托架500与下壳体202的固定。
安装板2022A上设置有贯穿的装配槽，该装配槽为上部开口的U型槽，光纤适配器可嵌在该装配槽内进行固定。安装板2022A上的装配槽包括第一装配槽与第二装配槽，第一装配槽与第二装配槽前后方向设置，第一装配槽靠近下壳体202的前侧侧壁，第二装配槽靠近下壳体202的后侧侧壁。第一光纤适配器700嵌在第一装配槽内，第二光纤适配器800嵌在第二装配槽内。
图18为根据一些实施例的一种光模块中适配器卡槽的结构示意图；图19为根据一些实施例的一种光模块去掉上壳体后的俯视图。如图18、图19所示，本公开实施例提供的光口 托架500包括相对设置的两侧壁610、朝向下壳体202的右侧面620与背向下壳体202的左侧面、上表面与下表面，光口托架500上设有贯穿的装配孔，该装配孔贯穿光口托架500朝向下壳体202的右侧面620与背向下壳体202的左侧面。在本公开的某一些实施例中，光口托架500上设有并排设置的第一装配孔630与第二装配孔640，第一装配孔630与第二装配孔640沿着光口托架500的前后方向依次设置，即第一装配孔630与第二装配孔640沿着光口托架500的一侧壁向相对的另一侧壁的方向依次设置。
第一装配孔630与第一光纤适配器700相对应，外部光纤穿过光口托架500的第一装配孔630与第一光纤适配器700的一端连接，第一光纤适配器700的另一端通过内部光纤与光发射组件400A连接，从而光发射组件400A发射的信号光经由第一光纤适配器700传输至外部光纤，以实现信号光的发射。第二装配孔640与第二光纤适配器800相对应，外部光纤穿过光口托架500的第二装配孔640与第二光纤适配器800的一端连接，第二光纤适配器800的另一端通过内部光纤与光接收组件500A连接，从而外部光纤传输的信号光经由第二光纤适配器800传输至光接收组件500A，以实现信号光的接收。
为方便将光口托架500插入下壳体202一端的安装槽2021A内，光口托架500前后方向的尺寸略小于安装槽2021A前后方向的尺寸，如此既可将光口托架500插在安装槽2021A内，又可减小光口托架500相对的两侧壁与安装槽2021A的侧壁之间的间隙，方便通过胶水固定光口托架500与安装槽2021A的侧壁。
光口托架500的右侧端面设置有U型槽，该U型槽上侧开口，且该U型槽与光口托架500的装配孔相连通，且将光口托架500安装至下壳体202内的安装槽2021A后，光口托架500右侧端面的U型槽与下壳体202内安装板2022A上的装配槽相连通，第一光纤适配器700与第二光纤适配器800分别嵌设在组合后的U型槽内，以支撑固定第一光纤适配器700与第二光纤适配器800。
图20为根据一些实施例的一种光模块中下壳体与适配器卡槽的局部装配图一；图21为根据一些实施例的一种光模块中下壳体与适配器卡槽的局部装配图二；图22为根据一些实施例的一种光模块中下壳体与适配器卡槽的局部装配图三。如图20、图21、图22所示，将光发射组件400A、光接收组件500A等光引擎安装至电路板300上后，光口托架500由左至右插在下壳体202一端的安装槽2021A内，直至光口托架500朝向下壳体202的侧面620与下壳体202一端的安装板2022A的侧面相抵接，从而将光口托架500安装至下壳体202的安装槽2021A内，以降低光引擎的安装公差。
将光口托架500安装至下壳体202的安装槽2021A内后，为固定光口托架500，通过安装槽2021A相对的侧壁上设置的胶水点胶孔2025A向光口托架500与安装槽2021A相接触的侧面之间注入胶水，通过胶水实现光口托架500与下壳体202之间的固定连接。在本公开的一些实施例中，通过胶水点胶孔2025A注入胶水时，首先光口托架500与下壳体202的接触面通过胶水点胶孔2025A注入的UV胶水进行预固定，再通过胶水点胶孔2025A注入的结构胶水对光口托架500与下壳体202的接触面进行加固，以保证光口托架500与下壳体202的安装固定性。
通过胶水点胶孔2025A注入胶水时，胶水点胶孔2025A可以做成不同形状的固定结构，以方便通过该胶水点胶孔2025A向光口托架500与下壳体202的接触面注入胶水，如长方形孔、圆形孔或异形孔，以顺利将UV胶水、结构胶水通过胶水点胶孔2025A注入光口托架500与下壳体202的接触面，保证光口托架500与下壳体202的固定连接。
图23为根据一些实施例的一种光模块中下壳体与适配器卡槽的装配侧视图；图24为根据一些实施例的一种光模块中下壳体与适配器卡槽的分解侧视图。如图23、图24所示，本公开实施例提供的下壳体202一端的安装槽2021A的底面可由下壳体202的左端开口延伸至下壳体202内的安装板2022A，如此光口托架500的底面与安装槽2021A的整个底面相粘接；还可在下壳体202中安装槽2021A的底面开一缺口2024A，该缺口2024A由下壳体202的一侧壁延伸至下壳体202的另一侧壁，且该缺口2024A的左侧与下壳体202的左端开口平齐，使得该缺口2024A呈U型结构，即安装槽2021A的左端端面与下壳体202的左端开口之间存在一定的距离，然后一直延伸至下壳体202内安装板2022A，如此光口托架500右部的部分底面与安装槽2021A的底面相粘接。
在安装槽2021A的左端设置缺口2024A后，可减少光口托架500的底面与安装槽2021A的底面之间的粘接面积，在光口托架500的底面涂覆胶水，再将光口托架500由左至右移动至安装槽2021A内，光口托架500底面的胶水粘接光口托架500的底面与安装槽2021A的底面。减小安装槽2021A的底面面积后，可减小光口托架500与安装槽2021A的粘接力，方便光口托架500安装至下壳体202的安装槽2021A内，以降低光发射组件400A、光接收组件500A等光引擎的安装公差。
在本公开的一些实施例中，不仅可在下壳体202中安装槽2021A的左侧开口，将光口托架500由左至右安装至安装槽2021A内，还可将光口托架500由上至下安装至安装槽2021A内。光口托架500的底面涂覆有胶水，当光口托架500由上至下安装至安装槽2021A、且光口托架500的底面与安装槽2021A的底面相接触时，光口托架500底面的胶水粘接光口托架500与下壳体202。
将光口托架500与下壳体202中安装槽2021A的底面相粘接后，首先通过下壳体202侧壁上的胶水点胶孔2025A向光口托架500的侧壁610与安装槽2021A的侧壁2023A之间注入UV胶水，以对光口托架500的侧壁610与安装槽2021A的侧壁2023A进行预固定；然后通过下壳体202侧壁上的胶水点胶孔2025A向光口托架500的侧壁610与安装槽2021A的侧壁2023A之间注入结构胶水，以对光口托架500的侧壁610与安装槽2021A的侧壁2023A进行加固。
光口托架500的上表面为高低不平的表面，包括第一侧面650与第二侧面660，第一侧面650远离下壳体202的左侧端面，第二侧面660靠近下壳体202的左侧端面，且第二侧面660内陷于第一侧面650，上壳体201的侧面压合于该第二侧面660上。另外，光口托架500的第二侧面660上端开口，以与上壳体201进行装配固定。
图25为根据一些实施例的一种光模块中上壳体的结构示意图；图26为根据一些实施例的一种光模块中上壳体的另一角度结构示意图。如图25、图26所示，上壳体201朝向光口托架500的一端设置有避让孔2011A，该避让孔2011A与光口托架500的第一侧面650相对应，且该避让孔2011A朝向光口托架500的端面开口，即避让孔2011A位于上壳体201的左侧，避让孔2011A的左侧端面与上壳体201的左侧端面重合，且避让孔2011A的左侧端面与上壳体201的左侧端面开口，使得避让孔2011A的结构为U型孔。
将上壳体201盖合于下壳体202时，光口托架500上端的第一侧面650嵌在上壳体201左侧的避让孔2011A内，使得光口托架500的第一侧面650与上壳体201的上表面相平齐；上壳体201靠近避让孔2011A的侧面压合于光口托架500的第二侧面660上，以对光口托架500进行上下限位。
上壳体201朝向下壳体202的侧面上设有凹槽，该凹槽的下侧面开口，该凹槽与光口托架500右侧部分、上端开口的装配孔相对应设置，使得上壳体201下表面的凹槽与光口托架500右侧的装配孔组合形成完整的装配孔，即上壳体201中凹槽的下侧面开口与光口托架500右侧的上部开口相匹配连接，以将光口托架500右侧、上部开口的装配孔与上壳体201下侧的凹槽连接。
在本公开的某一些实施例中，上壳体201下侧的凹槽包括第一凹槽2012A与第二凹槽2013A，第一凹槽2012A与光口托架500的第一装配孔630相匹配连接，第二凹槽2013A与光口托架500的第二装配孔640相匹配连接。如此，方便将外部光纤穿过光口托架500内的第一装配孔630、第二装配孔640与电路板300上的光发射组件400A、光接收组件500A相连接。
为将上壳体201下侧的凹槽与光口托架500右侧的装配孔相匹配连接，上壳体201下侧凹槽的左端面开口，与上壳体201左端的避让孔2011A相连通，以形成贯穿光口托架500左右端面的装配孔。
本公开实施例提供的光模块包括上壳体、下壳体、光引擎、适配器卡槽与光纤适配器，上壳体盖合于下壳体上形成容纳腔体，光发射次模块、光接收次模块等光引擎设置于该容纳腔体内，被配置为实现光的发射或接收；下壳体的一端设置有胶水点胶孔，适配器卡槽相对的两侧面与胶水点胶孔所在的侧面接触，并通过胶水点胶孔注入的胶水与下壳体的侧面固定连接，以实现适配器卡槽与下壳体的活动连接，从而可降低光发射次模块、光接收次模块安 装时存在的安装公差；适配器卡槽朝向上壳体的侧面与上壳体压合连接，以通过上壳体对适配器卡槽进行上下方向限位；光纤适配器插在适配器卡槽内，与光引擎连接，以实现光的传输。本公开将适配器卡槽与下壳体相分离，将光引擎安装在上壳体与下壳体形成的容纳腔体后，将光纤适配器的一端通过内部光纤连接至光引擎、另一端插入适配器卡槽内，再将适配器卡槽通过胶水点胶孔注入的胶水与下壳体的侧面固定连接，如此当光引擎在容纳腔体内安装存在安装公差时，将适配器卡槽安装在下壳体时可降低光引擎、光纤适配器的安装公差，工序简单，制造难度较低，解决了光引擎安装公差较复杂的问题，保证了光模块的长期可靠性。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
