具体实施方式
下面将结合本公开实施例中的附图，对本公开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。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
光纤通信的核心环节之一是光、电信号的相互转换。光纤通信使用携带信息的光信号在光纤/光波导等信息传输设备中传输，利用光在光纤/光波导中的无源传输特性可以实现低成本、低损耗的信息传输；而计算机等信息处理设备使用的是电信号，为了在光纤/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，就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、电信号的相互转换功能，光信号与电信号的相互转换是光模块的核心功能。光模块通过其内部电路板上的金手指实现与外部上位机之间的电连接，主要的电连接包括供电、I2C信号、数据信号以及接地等；采用金手指实现的电连接方式已经成为光模块行业的主流连接方式，以此为基础，金手指上引脚的定义形成了多种行业协议/规范。
图1为光通信终端连接关系示意图。如图1所示，光通信终端的连接主要包括光网络终端100、光模块200、光纤101及网线103之间的相互连接；
光纤101的一端连接远端服务器，网线103的一端连接本地信息处理设备，本地信息处理设备与远端服务器的连接由光纤101与网线103的连接完成；而光纤101与网线103之间的连接由具有光模块200的光网络终端100完成。
光模块200的光口对外接入光纤101，与光纤101建立双向的光信号连接；光模块200的电口对外接入光网络终端100中，与光网络终端100建立双向的电信号连接；在光模块内部实现光信号与电信号的相互转换，从而实现在光纤与光网络终端之间建立信息连接；在本公开的某一些实施例中，来自光纤的光信号由光模块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的电信号由光模块转换为光信号输入至光纤中。
光网络终端具有光模块接口102，用于接入光模块200，与光模块200建立双向的电信号连接；光网络终端具有网线接口104，用于接入网线103，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，在本公开的某一些实施例中，光网络终端将来自光模块的信号传递给网线，将来自网线的信号传递给光模块，光网络终端作为光模块的上位机监控光模块的工作。
至此，远端服务器通过光纤、光模块、光网络终端及网线，与本地信息处理设备之间建立双向的信号传递通道。
常见的信息处理设备包括路由器、交换机、电子计算机等；光网络终端是光模块的上位机，向光模块提供数据信号，并接收来自光模块的数据信号，常见的光模块上位机还有光线路终端等。
图2为光网络终端结构示意图。如图2所示，光网络终端100包括电路板105，笼子106设置在电路板105的表面；电连接器设置在笼子106内部有，用于接入金手指等光模块电口；散热器107设置在笼子106上，具有增大散热面积的翅片等凸起部。
光模块200***光网络终端中，在本公开的某一些实施例中光模块的电口***笼子106内部的电连接器，光模块的光口与光纤101连接。
笼子106位于电路板上，电路板上的电连接器包裹在笼子中；光模块***笼子中，由笼子固定光模块，光模块产生的热量传导给笼子106，然后通过笼子上的散热器107进行扩散。
图3为本公开实施例提供的一种光模块结构示意图，图4为本公开实施例提供光模块分解结构示意图。如图3、图4所示，本公开实施例提供的光模块200包括上壳体201、下壳体202、解锁部件203、电路板300及光收发次模块400；
上壳体201盖合在下壳体202上，以形成具有两个开口的包裹腔体；包裹腔体的外轮廓一般呈现方形体，在本公开的某一些实施例中，下壳体包括底板以及位于底板两侧、与底板垂直设置的两个侧板。
两个开口中的一个开口为电口204，电路板的金手指从电口204伸出，***光网络终端等上位机中；另一个开口为光口205，用于外部光纤接入以连接光模块内部的光收发次模块400；电路板300、光收发次模块400等光电器件位于包裹腔体中。
采用上壳体、下壳体结合的装配方式，便于将电路板300、光收发次模块400等器件安装到壳体中，由上壳体、下壳体形成光模块最外层的封装保护壳体；上壳体及下壳体一般采用金属材料，利于实现电磁屏蔽以及散热；一般不会将光模块的壳体做成一体部件，这样在装配电路板等器件时，定位部件、散热以及电磁屏蔽部件无法安装，也不利于生产自动化。
解锁部件203位于包裹腔体/下壳体202的外壁，用于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。
解锁部件包括解锁器及锁定件，锁定件用于与上位机锁定，解锁器用于将锁定件与上位机分离以解锁；笼子106中具有锁定弹片，锁定弹片与锁定件抵接以实现光模块与上位机的锁定，解锁器推动锁定弹片，以将锁定弹片与锁定件分离，以解除光模块与上位机的锁定关系，从而可以将光模块从上位机的笼子里抽出。
电路板300上设置有电路走线、电子元件(如电容、电阻、三极管、MOS管)及芯片(如MCU、激光驱动芯片、限幅放大芯片、时钟数据恢复CDR、电源管理芯片、数据处理芯片DSP)等。
电路板通过电路走线将光模块中的用电器件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电功能。
电路板一般为硬性电路板，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；当光收发次模块位于电路板上时，硬性电路板也可以提供平稳的承载；硬性电路板还可以***上位机笼子中的电连接器中，在本公开的某一些实施例中，在硬性电路板的一侧末端表面形成金属引脚/金手指，用于与电连接器连接；这些都是柔性电路板不便于实现的。
部分光模块中也会使用柔性电路板，作为硬性电路板的补充；柔性电路板一般与硬性电路板配合使用，如硬性电路板与光收发次模块之间可以采用柔性电路板连接。
光收发次模块与电路板实现电连接，其包括光发射次模块及光接收次模块两部分，分别用于实现光信号的发射与光信号的接收。光发射次模块及光接收次模块可以结合在一起，也可以相互分离。
图5为本公开实施例提供的解锁部件与下壳体的结构示意图。图6为本公开实施例提供的解锁部件与下壳体的分解示意图。图11为本公开实施例提供的解锁器的第一角度结构示意图。图12为本公开实施例提供的解锁器的第二角度结构示意图。图13为本公开实施例提供的解锁器的第三角度结构示意图。图14为本公开实施例提供的解锁器的刨面图。图15为本公开实施例提供的手柄的结构示意图。图16为本公开实施例提供的下壳体的结构示意图。图17为本公开实施例提供的未转动手柄时光模块的部分结构示意图。图18为本公开实施例提供的转动手柄时光模块的部分结构示意图。如图5、6和11-18所示，本公开实施例中，解锁部件203包括手柄2031和解锁器2032，下壳体202的外表面设置有置物槽2021、锁定件2022、第一限位柱2023和第二限位柱2024。在本公开的某一些实施例中，手柄2031包括依次连接的第一边20311、第二边20312、第三边20313、第四边20314、第一凸起20315和第五边20316，其中，第五边20316与第一边20311连接。第二边20312 作为手柄2031前端。第四边20314、第五边20316和第一凸起20315组成手柄2031末端。第一边20311和第三边20313作为手柄2031中间端。手柄2031中间端连接手柄2031前端和手柄2031末端。
手柄2031，末端中间位置形成第一凸起20315。由于第四边20314、第五边20316和第一凸起20315组成手柄2031末端，且第四边20314和第五边20316分别位于第一凸起20315的两侧，则第一凸起20315位于手柄末端中间位置。
为了增大解锁器2032的运动行程，第一凸起20315相对于手柄2031末端向左侧(光口端)倾斜。当第一凸起20315相对于手柄2031末端向左侧(光口端)倾斜时，第一凸起20315与解锁器2032前端之间的垂直距离为D1。当第一凸起20315相对于手柄2031末端不倾斜时，第一凸起20315与解锁器2032前端之间的垂直距离为D2。其中，D2大于D1。由于解锁器2032向右侧(电口端)滑动的运动行程由第一凸起20315与解锁器2032前端之间的垂直距离决定，且D2大于D1，因此，第一凸起20315相对于手柄2031末端向左侧(光口端)倾斜，增大了解锁器2032的运行行程。
第一凸起20315，可以是无下底边的梯形结构，也可以是有下底边的梯形结构。在本公开的某一些实施例中，
当第一凸起20315是无下底边的梯形结构时，该第一凸起20315包括第六边203151、第七边203152和第八边203153，第六边203151和第八边203153分别为该梯形结构的腰，第七边203152为该梯形结构的上底边。其中，第四边20314、第六边203151、第七边203152、第八边203153和第五边20316依次连接。
当第一凸起20315是有下底边的梯形结构时，该第一凸起20315包括第六边203151、第七边203152、第八边203153和第九边，第六边203151和第八边203153分别为该梯形结构的腰，第七边203152为该梯形结构的上底边，第九边为该梯形结构的下底边。其中，第四边20314、第六边203151、第七边203152、第八边203153和第五边20316依次连接，且第九边的两端分别连接第四边20314和第五边20316。
手柄2031还包括一个U型结构件。由于手柄2031除了手柄2031末端外，还包括第一边20311、第二边20312和第三边20313，第一边20311、第二边20312和第三边20313组成一个U型结构件。
手柄2031，边廓置于所述置物槽，以使所述手柄可以围绕置物槽转动。在本公开的某一些实施例中，手柄2031的第四边20314、第五边20316和第一凸起20315均置于置物槽2021内。未转动手柄2031时，第一凸起20315置于置物槽2021左侧(光口端)。转动手柄2031时，第一凸起20315由置物槽2021左侧(光口端)转向置物槽2021右侧(电口端)。
解锁器2032，前端设置第二凸起20321，中间设置有通孔20322，末端设置倾斜结构20323，用于沿着下壳体202的外表面滑动。在本公开的某一些实施例中，第二凸起20321，与第一凸起20315接触，在第一凸起20315由光口端转向电口端的推动下，第一凸起挤压第二凸起，以驱动解锁器移动，实现解锁器向电口端滑动。在本公开的某一些实施例中，第二凸起20321包括第一侧面203211、第二侧面203212、倾斜面203213、第三侧面203214、 第四侧面203215和第五侧面203216。第一侧面203211垂直于解锁器2032的外表面。第二侧面203212，平行于解锁器2032的外表面，前端与第一侧面203211连接。倾斜面203213，前端与第二侧面203212连接。第三侧面203214，前端与倾斜面203213末端连接，平行于第二侧面203212，沿着解锁器的2032外表面滑动。第四侧面203215，前端与第三侧面203214末端连接，平行于第一侧面203211，与解锁器2032的前端连接。第五侧面203216，前端与第三侧面203214末端连接，末端与第一侧面203211前端连接，平行于第三侧面203214，与解锁器2032的外表面连接。第二凸起20321的倾斜面203213与第一凸起20315接触，当第一凸起20315由光口端转向电口端时，第一凸起20315推动第二凸起20321的倾斜面203213向电口端滑动。
为了增加第二凸起20321向右侧滑动路程，倾斜面203213末端相对于倾斜面203213前端更凹陷。倾斜面203213末端相对于倾斜面203213前端更凹陷，指的是：倾斜面203213末端与第一侧面203211之间的垂直距离大于倾斜面203213前端与第一侧面203211之间的垂直距离。由于，第一凸起20315，首先与倾斜面203213前端接触，沿着倾斜面203213向下滑动，最后与倾斜面203213末端接触。因此，使用过程中，首先，第一凸起20315与倾斜面203213前端接触，第一凸起20315推动第二凸起向电口端滑动至第一位置处。随着第一凸起20315沿着倾斜面203213前端至倾斜面203213末端滑动，第一凸起20315逐渐由第一位置处推至第二位置处。其中，第二位置处第一凸起20315与倾斜面203213末端接触，且第二位置处相对于第一位置处更接近电口端。
通孔20322，内设置有弹性件，比如复位弹簧2033。在本公开的某一些实施例中，通孔20322一端设置有第三凸起203221。第三凸起203221，用于将复位弹簧2033***，以连接复位弹簧2033。
倾斜结构20323，末端相对前端更凹陷，用于根据解锁器2032向电口端滑动，推动上位机的弹片顶起，实现锁定件2022从卡口脱离。在本公开的某一些实施例中，倾斜结构20323末端相对于倾斜结构20323前端更凹陷，指的是：倾斜结构20323末端相对于解锁器末端之间的垂直距离大于倾斜结构20323前端相对于解锁器末端之间的垂直距离。倾斜结构的末端形成缺口，缺口可以容纳锁定件。
使用过程中，首先，倾斜结构20323末端与上位机的弹片接触；随着倾斜结构20323向右侧(电口端)滑动，倾斜结构20323表面逐渐与上位机的弹片接触，上位机的弹片逐渐顶起；当倾斜结构20323向右侧(电口端)滑动至第三位置处，倾斜结构20323前端与上位机的弹片接触，上位机的弹片被大幅度顶起，使得锁定件2022脱离上位机的卡口，解除光模块与上位机之间的固定连接。
置物槽2021，设置于下壳体202外表面靠近光口端的位置处。置物槽2021相对于下壳体202外表面更凹陷。手柄2031末端置于置物槽2021内。当未转动手柄2031时，手柄2031末端位于置物槽2021左侧(光口端)；当转动手柄2031时，手柄2031末端由置物槽2021左侧(光口端)转向右侧(电口端)。
锁定件2022，与上位机的卡口配合，以实现光模块与上位机之间的固定连接。锁定件2022的形状也为三角形，上位机的卡口的形状为三角形，且卡口与锁定件2022的夹角和 边长尺寸完全匹配。即锁定件2022的夹角与卡口的夹角相等，且锁定件2022的边长尺寸小于卡口的边长尺寸。当卡口的边长尺寸小于锁定件2022的边长尺寸时，锁定件2022无法***卡口中，无法实现光模块与上位机之间的连接。当卡口的边长尺寸等于锁定件2022的边长尺寸时，锁定件2022可以***卡口中，但由于二者刚好卡住，容易磨损锁定件2022。
第一限位柱2023，置于通孔20322内，用于限制复位弹簧2033。复位弹簧2033，前端***第一限位柱2023中，第二端连接于第三凸起203221。第一限位柱2023不动，当未转动手柄2031时，第三凸起203221置于位置1处，复位弹簧2033处于自然伸长状态；当转动手柄2031时，第三凸起203221由位置1处滑至位置2处，复位弹簧2033处于压缩状态。其中，位置2处于位置1的右侧，即位置2相对于位置1更接近电口端。
第一限位柱可以设置在下壳体外壁表面。
第二限位柱2024，用于限制解锁器2032仅沿着下壳体202的外表面左右滑动。在本公开的某一些实施例中，下壳体202的外表面设置有多个第二限位柱2024，多个第二限位柱2024分别对称设置于下壳202的外表面，多个第二限位柱2024组成一个滑动槽，解锁器2032仅能沿着该滑动槽由左侧(光口端)至右侧(电口端)滑动，不能上下滑动。
图7为本公开实施例提供的盖板的第一角度结构示意图。图8为本公开实施例提供的盖板的第二角度结构示意图。图9为本公开实施例提供的盖板的第三角度结构示意图。图10为本公开实施例提供的盖板的剖面图。如图5-18所示，本公开实施例中，光模块还包括盖板206。在本公开的某一些实施例中，盖板206用于将解锁部件203固定于下壳体202上。在本公开的某一些实施例中，盖板206盖于解锁器2032上，解锁器2032盖于下壳体202上，盖板206、解锁器2032和下壳体202组成一个夹心结构，即盖板206将解锁器2032固定于下壳体202上。其中，解锁器2032为夹心部分。
第一限位柱可以设置在盖板朝向解锁器的表面；第二限位柱可以设置在盖板朝向解锁器的表面。
盖板206，前端设置有第一凹槽2061。第一凹槽2061，用于为第二凸起20321提供滑动空间。由于第二凸起20321的上表面高于盖板206的下表面，当盖板206前端不设置第一凹槽2061时，第二凸起20321无法向右侧(电口端)滑动。当盖板206前端设置第一凹槽2061时，盖板206为第二凸起20321提供滑动空间，第二凸起20321可向右侧(电口端)滑动。
为了进一步增加第二凸起20321的运动行程，本公开实施例中，第一凹槽2061内设置第二凹槽2062。第二凹槽2062，相对于第一凹槽2061更凹陷，与第二凸起20321对应。第二凹槽2062的设置，相当于为第二凸起20321提供了更多滑动空间，进一步增加第二凸起20321的运动行程。
为了在盖板206盖于解锁部件203时，方便解锁器2032沿着下壳体202的外表面滑动，盖板206的内表面设置有滑动凹槽2063。滑动凹槽2063，与解锁器2032对应，宽度尺寸大于解锁器2032的宽度尺寸，高度尺寸大于解锁器2032的高度尺寸，解锁器可以在滑动凹槽中滑动。
本公开提供了一种光模块，包括下壳体和与下壳体连接的解锁部件。下壳体的外表面 靠近光口端的位置处设置有置物槽，下壳体的外表面还设置有锁定件。锁定件，与上位机的卡口配合，以实现光模块与上位机之间的固定连接。解锁部件用于实现或解除光模块与上位机之间的固定连接。解锁部件包括手柄和解锁器。手柄，末端置于置物槽内，末端中间位置形成第一凸起。解锁器，前端设置有第二凸起，中间设置有通孔，末端设置倾斜结构，用于沿着下壳体的外表面滑动。第二凸起，与第一凸起接触，在第一凸起由光口端转向电口端的推动下，实现向电口端滑动。通孔内设置有复位弹簧。倾斜结构，与上位机的弹片对应，相对锁定件更靠近光口端，末端相对前端更凹陷，用于根据解锁器向电口端滑动，推动弹片顶起，实现锁定件从卡口脱离。未转动手柄时，第一凸起置于置物槽左侧，第二凸起置于下壳体的外表面的置物槽边缘处，倾斜结构远离与上位机的卡口配合的锁定件，锁定件卡合于上位机的卡口，实现光模块与上位机之间的固定连接。转动手柄时，第一凸起由置物槽的左侧转向右侧，第二凸起沿着下壳体的外表面向电口端滑动，倾斜结构逐渐接近锁定件，倾斜结构的末端先与弹片接触，倾斜结构的前端再与弹片接触。由于倾斜结构的末端相对前端更凹陷,倾斜结构不断接触弹片，推动弹片不断顶起，直至锁定件脱离卡口，解除光模块与上位机之间的固定连接。本公开，转动手柄，第一凸起向右侧转动，推动第二凸起沿着下壳体的外表面向电口端滑动，倾斜结构逐渐接触弹片，推动弹片不断顶起，直至锁定件脱离卡口，解除光模块与上位机之间的固定连接。
最后应说明的是：以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的精神和范围。
