如图1至图21所示，一种光电混合连接器，包括壳组件1、导光组件2以及导电组件3。
其中，壳组件1包括前后贯通的容纳空间11，容纳空间11用于容纳其他部件，壳组件1的外侧可与光模块、光电混合适配器等进行插接配合。
导光组件2包括尾柄21、插芯22以及光纤23。其中，光纤23包括塑胶外层(未标出)、包层(未标出)以及设置在包层内的纤芯。纤芯可为玻璃纤芯，用于传递光信号，塑胶外层用于提供防护。
插芯22设置在尾柄21的一端上；光纤23依次穿设在尾柄21与插芯22中，直至纤芯与插芯22的远离尾柄21的一端齐平。光信号在纤芯中传输，直至到达插芯22的一端面，再通过与插芯22光耦合对接的部件完成 光信号的传递。本处的部件可以是另一个光电混合连接器的插芯22、也可以是光模块的光插口。容纳空间11中可以设置相应的凹槽、挡块与尾柄21相配合，完成轴向限位，以使得尾柄21设置在容纳空间11中。
导电组件3包括至少一个导电插针31以及与导电插针31连接的电缆32。导电插针31与插芯22位于容纳空间11的同侧，以使得导电插针31与插芯22在同侧共用一个插接部件，一次插接即可以完成光电通道的建立，一来可以简化插接操作，一来也可以避免误操作导致光电通道不顺畅，有效实现光电的传输。根据结构功能的需要，导电插针31的数量可为一个、两个、或者三个及以上。
在本申请各个实施例中，导电插针31与电缆32可以直接连接以形成电传输通道；导电插针31与电缆32也可以通过一段金属筒体连接，金属筒体起到过渡连接的效果，以防止导电插针31与电缆32连接失效。
导电插针31可部分的伸出容纳空间11。具体地，如图1至图5所示，导电插针31与电缆32连接的一端固定在容纳空间11内，导电插针31远离电缆32的一端沿轴向延伸直至凸出容纳空间11，以方便与电气耦合的部件完成电的传递。如图6至图11所示，导电插针31也可以固定在壳组件1的外侧，以使得导电插针31整体均在容纳空间11的外部，导电插针31远离电缆32的一端沿轴向向前延伸直至越过壳组件1的前端以形成凸出部，凸出部与电气耦合的部件完成电的传递。本处的部件可以是另一个光电混合连接器的导电插针31、也可以是光模块的电插口、还可以是5G终端设备上的电接头。
导电插针31与电缆32构成电传输通道以实现电的传输。本处的电可以是供给终端设备的电能，也可以是与具有客户业务数据的电信号。
以传输电信号为例，现有技术中，光通信设备包括一种或多种类型的单板，以完成客户业务数据的处理、传输和交换等功能。光模块是光通信 设备重要的组件之一，用于实现客户业务数据承载在光信号进行发送和/或从光信号中解析出客户业务数据。对应的，光模块具有光插口以及电插口，以分别接收/发射光信号和电信号。在本申请实施例中，导电插针31与光模块的电插口43(下文提及)电气连接，以建立传输电信号的通道。光模块的光插口42(下文提及)与导光组件2的插芯22内的光纤23进行光耦合连接，以建立传输光信号的通道。外部发出的光信号经过光纤23进入光模块的光插口42，光模块处理光信号转化为电信号，电信号通过电插口43传递给终端设备；过程反过来实施也是可以的，终端设备发出的电信号经过导电插针31传递到光模块的电插口43，光模块处理电信号转化为光信号，光信号通过光插口42传递到导光组件2的插芯22内的光纤23中，再传递到另一端的终端设备。由此完成光信号、电信号接收、转化以及传递过程。
以供给终端设备的电能为例，现有技术中，光通信设备的运转本身需要电力供应，尤其在5G应用中，很多对应的光接头以及供给终端设备的电接头，终端设备可以为AP(英文：Acess Point)、室内天线、摄像头和PC(英文：Personal Computer)端等。本申请实施例中，导电插针31与电插口43电气连接；电缆32接收的电能通过导电插针31传递给电插口43，光模块将该电能传递给终端设备，以供终端设备运转；导光组件2的插芯22内的光纤23与光插口42进行光耦合连接，以建立传输光信号的通道，终端设备发出的电信号传递给光模块，光模块将电信号转化为光信号，光信号通过光插口42进入光纤23以实现传输；完成相应的光信号接收、转化以及传递过程。
一种可能的实施例，如图1至图11所示，壳组件1包括外壳12、后套13以及尾套14。外壳12包括具有第一贯通孔121的壳本体122。后套13为具有第二贯通孔131的套筒。尾套14为具有第三贯通孔141的套筒。
外壳12与后套13嵌套以形成前后贯通的容纳空间11；也即是壳本体 122与后套13嵌套，第一贯通孔121与第二贯通孔131贯通以形成容纳空间11；方便容纳导光组件2。尾套14嵌套在后套13远离外壳12的一端。
光纤23穿过第三贯通孔141进入容纳空间11，去除塑胶外层的光纤23再依次穿设在尾柄21与插芯22中，直至纤芯与插芯22的远离尾柄21的一端齐平。
可以理解的是，结构的设计是多样的，因此导光组件2中的各个部件不一定全部在容纳空间11中，只需要通过设置尾柄21固定在容纳空间11中，例如可以在壳本体122以及后套13内设置相应的定位槽、定位块与尾柄21相配合，完成轴向限位，以使得尾柄21设置在容纳空间11中；其余部件直接或者间接的与尾柄21固定即可。
插芯22远离尾柄21的一端突出于容纳空间11，插芯22从壳本体122远离后套13的一端突出，以方便插芯22远离尾柄21的一端插设在对应的部件中。
本处的部件是指的光模块的光插口、光电混合适配器的套筒件53(下文提及)。
以部件为套筒件53为例，两个光电混合连接器9的导光组件2的插芯22能够分别从套筒件53的两侧插入，以实现光耦合对接，套筒件53可提供密封、保护以及导向等功能。
一种可能的实施例，如图1至5所示，导电插针31设置在尾柄21上，以实现固定，电缆32穿过尾柄21与导电插针31连接构成电传输通道以实现电的传输。
一种可能的实施例，如图1至5所示，尾柄21包括柄本体211以及沿柄本体211的径向外凸的凸块212，柄本体211可为塑料件或者陶瓷件，凸块212可为绝缘的塑料件，凸块212形成有沿柄本体211的轴向的第一通孔2121，导电插针31的一端插设在第一通孔2121中；以实现导电插针31 的固定。电缆32可伸入第一通孔2121中与导电插针31连接，可以实现电气绝缘，避免电泄露。凸块212与柄本体211可以一体加工，连接强度好；也可以分别制作，然后通过粘接、卡接或者焊接的方式固定两者。
一种可能的实施例，如图1至5所示，容纳空间11的壁面上形成有避让导电插针31的让位槽111。具体地，让位槽111可以是外壳12内凹形成，也可以是后套13穿孔形成，只要能防止与导电插针31干涉即可。
一种可能的实施例，如图1至5所示，壳本体122的侧壁形成有连通外部环境与第一贯通孔121的第一通道1221。尾套14的侧壁形成有连通外部环境与第三贯通孔141的第二通道142。
电缆32的一端从尾套14远离后套13的一侧穿入第三贯通孔141，再通过第二通道142到达尾套14的外侧，再通过第一通道1221进入容纳空间11内与导电插针31连接。确保电缆32与导电插针31连接构成电传输通道以实现电的传输，并使得光电混合连接器的外形结构不变，以通用市面上的产品。
为了简化结构，电缆32与光纤23在穿过第三贯通孔141时可合为一股，电缆32穿过第二通道142时，电缆32与光纤23两者分离成两股，电缆32按照上述的路线进行布置，光纤23依次穿过尾柄21以及插芯组件。
一种可能的实施例，第一通道1221可为通孔，第二通道142可为通孔，通孔直径应略大于电缆32的直径，以方便电缆32穿设其中。
如图1至图5所示，第一通道1221也可为开放槽，开放槽延伸至壳本体122的侧壁的靠近后壳13一侧的边缘处且在侧壁的边缘处形成有开口，也就是说，第一通道1221贯穿壳本体122的侧壁的靠近后壳13一侧的边缘，使得第一通道1221具有长U形的开口，方便电缆32穿过第一通道1221。
同理，第二通道142也可为开放槽；开放槽延伸至尾套14的侧壁的靠近后壳13一侧的边缘处且在侧壁的边缘处形成有开口，也就是说，第二通 道142贯穿尾套14的侧壁的靠近后壳13一侧的边缘，使得第二通道142具有长U形的开口，方便电缆32穿过第二通道142。
一种可能的实施例，如图6至图11所示，导电插针31设置在壳组件1外侧。具体地，导电插针31可以设置在外壳12、后套13或者尾套14的其中一个上，具体以设计为准，只要能确保导电插针31与壳组件1相对固定即可。在本实施例中，导电插针31可设置在外壳12的外侧。
一种可能的实施例，如图6至图11所示，导电插针31设置在壳本体122的外侧面上。尾套14的侧壁形成有连通外部环境与第三贯通孔141的第二通道142；
电缆32的一端从尾套14远离后套13的一侧穿入第三贯通孔141，再通过第二通道142到达尾套14的外侧与导电插针31连接。确保电缆32与导电插针31连接构成电传输通道以实现电的传输，并使得光电混合连接器的外形结构不变，以通用市面上的产品。
类似的，为了简化结构，电缆32与光纤23在穿过第三贯通孔141时可合为一股，电缆32穿过第二通道142时，电缆32与光纤23两者分离成两股，电缆32按照上述的路线进行布置，光纤23依次穿过尾柄21以及插芯组件。
如图6和图7所示，导电插针31可以直接插入壳本体122的侧壁中，结构简单，连接处的强度好，但这样对壳本体122的尺寸要求、绝缘性能、以及硬度均有较高要求。
一种可能的实施例，如图8至图11所示，导电组件3包括设置在壳本体122的侧壁上的固定座34。其中，壳本体122可为注塑件，固定座34可为绝缘的塑料件或者橡胶件；固定座34形成有沿轴向的第二通孔341，导电插针31的一端插设在第二通孔341中。以实现导电插针31的固定。电缆32可伸入第二通孔341并与导电插针31连接，可以实现电气绝缘，避 免电泄露。将固定座34与壳本体122可以分别制作，然后通过粘接、卡接或者焊接的方式固定两者，降低工艺难度以及成本。
一种可能的实施例，如图1至图11所示，外壳12包括设置在壳本体122的侧壁上的弹性卡板125，与光电混合连接器配合的部件可以设置相应的轴向限位孔(未标出)以限制壳组件1的轴向位移。本处的部件可以为光模块、或者光电混合适配器。
弹性卡板125形成有供电缆32穿过的第三通道126，以避免弹性卡板125与电缆32干涉。第三通道126可为通孔，通孔直径应略大于电缆32的直径，以方便电缆32穿设其中。
一种可能的实施例，如图1至图11所示，壳组件1包括弹性件15。弹性件15可以为弹簧。弹性件15设置在容纳空间11中，弹性件15的一端抵于后套13，另一端抵触在尾柄21上。弹性件15通过尾柄21向插芯22提供作用力，当两个光电连接器9的导电组件3的插芯22分别从套筒件53的两侧插入，弹性件15可改变长度体积以使得两者不会硬接触，并依靠该弹性件15的作用力使得两个插芯22对接紧密，完成光耦合对接。同理，光电连接器9的导电组件3的插芯22与光模块的光插口42(下文提及)装配，依靠该弹性件15的作用力使得两者对接紧密，完成光耦合对接。
本申请再提供一种光模块，与上述各实施例的光电混合连接器9配合，如图1至12所示，光模块包括电板41、光插口42以及电插口43。
光插口42与电插口43设置在电板41的同一端，以使得光电混合连接器9的导电插针31与插芯22在插接在光模块的同一端，避免在光模块的两端分别进行两次插接操作，简化插接操作，也可以避免插接错误导致光电通道不顺畅。
光插口42与光电混合连接器9的插芯22插接，两者光耦合以建立传输光信号的通道。电插口43与对应的导电插针31插接，两者电气连接。 本领域的技术人员应当知晓，电板41上设置有完成光模块功能所必要的电器元件，在此不做赘述。
以电插口43是用于传输电信号为例，外部发出的光信号经过插芯22内的光纤23进入光模块的光插口42，光模块处理光信号转化为电信号，电信号通过电插口43传递给终端设备；过程反过来实施也是可以的，终端设备发出的电信号经过导电插针31传递到光模块的电插口43，光模块处理电信号转化为光信号，光信号通过光插口42传递到导光组件2的插芯22内的光纤23中，再传递到外部。由此完成光信号、电信号接收、转化以及传递过程。
以电插口43是用于供给终端设备的电能为例，导电插针31与电插口43电气连接；电缆32接收的电能通过导电插针31传递给电插口43，光模块将该电能传递给终端设备，以供终端设备运转；导光组件2的插芯22内的光纤23与光插口42进行光耦合连接，以建立传输光信号的通道，终端设备发出的电信号传递给光模块，光模块将电信号转化为光信号，光信号通过光插口42进入光纤23以实现传输；完成相应的光信号接收、转化以及传递过程。
一种可能的实施例，如图12所示，光模块包括模块壳体44，可提供固定、保护以及防尘等功能。电板41固定于模块壳体44的内部，模块壳体44的端部形成有容纳光插口42与电插口43的安装孔441，安装孔441配置为与壳组件1插接，安装孔441内可以对应的设置定位槽、定位挡板等部件以使得壳组件1在安装孔441内轴向固定以及周向固定。
本处再提供一种光电混合适配器，与上述任一项实施例的光电混合连接器9配合，如图1至图11、图13至图19所示，光电混合适配器包括本体51、支撑部52、套筒件53以及导电部54。
本体51内形成有至少一个轴向贯通的通道511。支撑部52支撑在通道 511内且将通道511隔为两个子通道511a，两个子通道511a分别与对应的光电混合连接器9的壳组件1插接配合。套筒件53中空且沿通道511的轴向设置，套筒件53设置在支撑部52上并连通两个子通道511a。套筒件53的两端分别与对应的光电混合连接器9的插芯22插接配合；套筒件53提供密封、保护以及导向等功能，两个光电混合连接器9的插芯22在套筒件53内对接，插芯22端面的光纤23光耦合，以建立传输光信号的通道。
本体51可采用塑料件注塑成型；支撑部52可采用塑料件与本体51一体注塑成型；套筒件53可为支撑部52上形成的一个贯穿通道，两者一体成型；为了保证对接精度，套筒件53也采用陶瓷单独制成再在植入支撑部52中，一方面满足使用的精度要求一方面降低成本。
导电部54设置在支撑部52上，导电部54配置为使得两个光电混合连接器的导电插针31电连接。
一种可能的实施例，如图14和图15所示，导电部54可以为导电材质制成的筒体，导电部54的两端配置为分别与两个光电混合连接器的导电插针31电连接，以使得两个光电混合连接器的导电插针31实现电连接，此时导电部54起到导向作用以及导电作用。
可以理解的是，由于导电部54本身导电，因此两个光电混合连接器的导电插针31可以不用接触，因此，通过设计导电插针31、导电部54的长度，使得导电插针31插到底时不会出现硬接触，此时导电插针31可以为单一的金属杆。
一种可能的实施例，如图14和图15所示，导电部54为绝缘材质制成的轴向贯通的通孔，例如导电部54、支撑部52与本体51均为塑料并一体成型制成。导电部54的两端配置为分别供两个光电混合连接器的导电插针31插入以使其抵触实现电连接。
一种可能的实施例，如图16至图19、以及图21所示，导电部54包括 轴向贯通的导向孔541以及设置在导向孔541中的导电体542，导电体542的两侧分别与两个光电混合连接器的导电插针31电连接。导电体542为金属导体，以黄铜、铝等导电性质良好的材质制成，以方便电连接。
如图19所示，导电体542可为一端开口的套筒，导电插针31可以为单一的金属杆，通过设计套筒的深度以及导电插针31的长度，使得导电体542的闭口一端与另一个光电混合连接器的导电插针31抵触，导电体542的开口一端与一个光电混合连接器9的导电插针31实现孔轴插接，以调整长度配合，避免出现硬接触。
具体地，导电体542的开口一端，端口部可设置导向的喇叭口5421，以防止导电插针31插偏；导电体542的筒内壁5422与导电插针31的侧面315紧贴。而导电体542的闭口一端，导电插针31的尖端平面314抵触在导电体542的筒底面5423，从而实现两个光电混合连接器9的导电插针31的有效连接。
如图21所示，导电体542也可为具有两端面5424的金属导电柱体，导电体542的两端面5424分别与各一个光电混合连接器的导电插针31抵触，从而使得两个光电混合连接器的导电插针31实现电连接。
为了避免两个导电插针31出现硬接触导致破坏，上述各实施例中，若导电插针31抵触，则可设置导电插针31为可伸缩的部件，如图20所示，导电插针31包括针管311、插设在针管311中的针头312以及设置在针管311内的弹性元件313。针管311可固定在尾柄21、外壳12、后壳13或者尾套14上，导电插针31配置为针头312的端面相对于壳组件1可伸缩，以避免装配过程中出现硬接触。针头312的横截面为圆形、多边形的长柱体，材质可以为导电性能良好的铜、钢、铝等。
