浮动件32与电路板5电连接。需要理解的是，本处的电连接可以是指的，浮动件32与电路板5之间通过铜箔、导线或者金属抵触以实现两者之间的电能 传递或者电信号传递；此外，本处的电连接还可以是指，浮动件32与电路板5两者之间不建立实体连接，而是以无线连接的形式，采用电磁感应形式进行电能传递或者电信号传递，具体地，浮动件32可激发出按照一定规律变化的电磁波，电路板5上设置有接收电磁波的感应装置，并将变化的电磁波转为电能，反之可由电路板5激发出按照一定规律变化的电磁波浮动件32上设置有接收电磁波的感应装置，并将变化的电磁波转为电能；由此在浮动件32与电路板5之间实现电能传递或者电信号传递。
光源4与电路板5电连接，浮动件32用于为光源4供电；即浮动件32通过电路板5向光源4提供电能，以激发出光信号。本领域技术人员可知，在光器件技术领域，光模块具备一个独立的封装，电路板5上集成有完成光电信号转换的必要元器件。
例如，电路板5上可集成光调制器(未标出)、复用器(未标出)、解复用器(未标出)等元器件。其中，光调制器用于将电信号加载到光能，从而输出带信号的光信号。具体地，电信号加载到光能以形成光信号的具体形式，可以改变光的相位、幅度等。不同波长的光信号可通过复用器合并形成一路光信号。一路包含多波长的光信号则通过解复用器拆分为多个单一波长的光信号。
浮动件32活动设置在固定座31上；浮动件32可相对于电路板5浮动。需要理解的是，本处的浮动是指的在浮动件32在不脱离固定座31的限制情况下，能相对于电路板5在一定范围内前后伸缩、左右摆动、或者水平偏移。由此，光模块插接在光通信设备内，电连接器83(下文提及)与浮动件32插拔产生的机械应力通过浮动件32自身的浮动获得释放，从而避免该机械应力通过电路板5传递到光接口2，使得光接口2能在外部干扰尽量小的情况下与光连接器82(下文提及)进行耦合，并实现提高光接口2的耦合精度的目的。
一种可能的实施例，如图1至图3所示，光模块包括柔性的导电件6，浮动件32通过导电件6与电路板5电连接，导电件6的一端连接到电路板5上的铜箔(未标出)或者其它元器件引脚接口(未标出)，连接的位置可为电路板5靠近电接口组件3的端面，也可以为电路板5的两侧部；导电件6的另一端与浮动件32实现固定连接以完成电路的导通。当电连接器83与浮动件32插拔产生机械应力，导电件6在保持两者电连接的情况下，导电件6可通过柔性变形消除浮动件32的机械应力，以使得浮动件32相对于电路板5做出的浮动不会影响到电路板5，进而防止机械应力传递到光接口2，提高光接口2的耦合精度的目的。
根据设计的需要，导电件6可为柔性电路板；导电件6也可为多芯排线；导电件6为多根可挠曲的导线。成本低，导电性能稳定且能通过自身有效的变形消除浮动件32的机械应力。
一个光模块可以与光通信设备上的一个电连接器82进行连接；此外，一个光模块可以与光通信设备上的多个电连接器82进行连接。如图5至图7所示，对于光模块而言，固定座31上的浮动件32可以根据需要设置为一个或者多个，多个浮动件32可以通过集成采用一个导电件6与电路板5实现电连接；每一个浮动件32可以单独的通过导电件6与电路板5实现电连接，此时导电件6的形式可以为上述导电件6的任意一种或者多种形式，具体以设计为准。
一种可能的实施例，如图1、图5至图7所示，电接口组件3包括弹性件33，浮动件32插设在固定座31中，弹性件33布置在浮动件32与固定座31之间，电接口组件3配置为浮动件32的端面相对于固定座31可伸缩，也即是浮动件32的端面相对于电路板5可伸缩；从而形成一个公插头，电连接器82形成为一个母插孔，浮动件32以公母插头的形式插入电连接器82中完成两者连接，相应的机械应力使得浮动件32发生前后伸缩、左右摆动、或者水平偏移等情况，从而避免机械应力传递到光接口2，最终提高光接口2的耦合精度。
具体地，如图7所示，浮动件32为一端开口的空心圆柱体，固定座31上形成有定位孔311，定位孔311的内径大于浮动件32的外径，两者间隙配合形成间隙C，0.01mm≤C≤0.5mm，以使得浮动件32可根据插入电连接器82中时产生的机械应力进行上下竖直偏移或者左右水平偏移；也可以以浮动件32其中一端为支点在角度B的范围内做出左右、上下摆动，1°≤B≤10°，在保持浮动件32与电路板5电连接的情况下，避免机械应力传递到光接口2，最终提高光接口2的耦合精度。
一种可能的实施例，浮动件32可为标准的USB接口，以使得光模块能通用现有的光通信设备，方便改进且两者插接方便；此时电连接器82对应的为USB插口。浮动件32与电连接器82连接时产生的机械应力使得浮动件32发生前后伸缩、左右摆动、或者水平偏移等情况，从而避免机械应力传递到光接口2，最终提高光接口2的耦合精度。
一种可能的实施例，如图1至图7所示，电路板5包括焊盘51，光源4包括电极41、发光端42和引脚43。发光端42朝向光接口2，以方便两者耦合。引脚43用于连接。
焊盘51与电极41一般可采用焊接方式实现电连接连接，此外，焊盘51 与电极41也可采用金丝键合工艺实现电连接；在保持导通的前提下，热膨胀系数小，适用光模块这种封装形式。光源4通过电极41接受电能，从而输出光能。
现有技术中，光模块的一端作为光接口与外部光纤相连，另一端作为电接口与外部通信设备相连。光接口与电接口分别处于光模块的两端，电接口首先插接，电接口插接时产生的机械应力通过电路板传递到光接口并影响光接口的二次插接精度。
在本申请中，通过设置电接口组件3的浮动件32相对于电路板5可有效的降低机械应力对光接口2的影响，使得光接口2的耦合精度高。
一种可能的实施例，如图1至图7所示，光接口2与浮动件32朝向同一方向。本领域技术人员可知，光接口2和浮动件32均有一个开口方向，用于和其他装置实现接口连接。具体地，光接口2和浮动件32朝向同一方向是指，光接口203和电接口204的开口方向的朝向相同。
光接口2和浮动件32用于同时插入光通信设备的光连接器82以及电连接器83中，或光接口2和浮动件32用于同时从光通信设备的光连接器82以及电连接器83中拔除，以较快地完成光模块与光通信设备的连接，避免光模块在光通信设备上的多次插拔，减少布线时间与成本。需要理解的是，浮动件32与光接口2插入光通信设备的光连接器82以及电连接器83中；两者均为第一次插拔，从而避免二次插拔对光接口2的耦合精度的影响；同时，浮动件32可以通过自身相对于电路板5的浮动来减少机械应力对光接口2的影响，最终提高光接口2的耦合精度。
如图1所示，光接口2和固定座31可以布置在壳组件1的底座13上(下文提及)，且开口对准后端。光接口2和固定座31此时可左右并排布置。
在其他的情况下，光接口2和固定座31可以布置在电路板5上，既可以左右并排布置并对准后端，也可以分别布置在电路板5的沿上下方向的面上并对准后端。
一种可能的实施例，如图1至图3所示，光模块包括拉环7以及具有容纳腔(未标出)的壳组件1，壳组件1包括顶盖(未显示)以及底座13。电路板5固定设置在容纳腔内。光接口2、电接口组件3以及光源4可布置在底座13上。拉环7布置在底座13远离光接口2的一端。拉环7上可设置锁定装置71，方便光模块与光通信设备插拔时锁定。
一种可能的实施例，如图1至图3所示，光源4包括多个发光端42；每一个发光端42作为独立的光源以分别发射。
其中，多个发光端42可沿垂直于电路板5的轴向的水平方向从左到右并排设置在电路板5的一端，或者，多个发光端42沿电路板5的轴向从前到后竖向设置在电路板5的一端，或者，多个发光端42分别布置在电路板5的一端的正反两面上。具体以设计为准。
一种光通信设备，包括上述各实施例的光模块、光连接器82以及电连接器83；光连接器82与光接口2可拆卸连接；电连接器83与浮动件32插拔连接。此外，光通信设备还包括至少能部分容纳光模块的笼体81，以方便光模块插拔。
笼体81上可设置有与锁定装置71相配合的锁扣装置12，当光模块插入笼体81时，光连接器82与光接口2对接，电连接器83与浮动件32连接；光模块与笼体81通过锁定装置71与锁扣装置12实现锁定防止分离。
锁定装置71可为弹性卡板，锁扣装置12可为卡槽。
一种可能的实施例，当光接口2与浮动件32朝向同一方向，即为光接口2与电接口组件2在底座13的同一端，此时，光通信设备的电连接器83和光连接器82可为集成的光电连接器，以减少插拔次数，提高光接口2的耦合精度。
一种可能的实施例，如图5至图7所示，浮动件32远离固定座31的前端面321为平滑过渡曲面；电连接器83包括有与浮动件32的端面电气对接的平面焊盘(未示出)；以方便传输电能。
一种可能的实施例，光模块还包含光学功能部件(未标出)，光源4发出的光经过光学功能部件进入光接口4中。光学功能器件包含透镜和/或阵列透镜和/或准直套筒和/或光纤，具体以设计为准。
本申请提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合。
以上所述仅为本申请的较佳实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
