下面结合附图和具体实施方式对本申请做进一步的说明。
光电复合缆是一种内含电缆和光纤的复合缆，通常电缆有两条，分别对应电源的正极和负极，光缆内包含光纤用于光通信。在一个使用端通常设置有电源，电源的正极和负极与两条光缆分别电连接，从而将电能输送至光电复合光纤连接器，同时在一个使用端光纤与光学设备进行光学信号传输，信号传输至光电复合光纤连接器。
根据本申请的第一种实施方式，一种光电复合光纤连接器，如图1、图2、图3和图4所示，主要包括：导电片1、陶瓷插芯组件2和内壳体3。
所述导电片1具有接触部4和连接部5，所述接触部4用于与外部设备进行电接触，外部设备可以为适配器、接续器或者电源等，所述连接部5用于与电缆进行电连接并形成结合部21。导电片1整体由片状的导体构成，材料通常为金属铜材质。接触部4高于连接部5设置，接触部4具有条状接触面，以便在光电复合光纤连接器插入过程中与适配器34的金属导电压
片35滑动接触。连接部5低于接触部4，如此便于与内壳体3配合进行固定。
连接部5用于与电缆进行电接触，电缆芯线为圆柱状，两者的结合可以通过焊锡焊接或者通过将连接部5尾部卷起包裹电缆芯线并压接电缆，如图5和图6所示，无论采用哪种方式，电缆在与片状的连接部5结合时会形成一个凸起，该凸起部分即为结合部21。
陶瓷插芯组件2，具有光学接口，所述陶瓷插芯组件2用于固定光纤。陶瓷插芯组件2主要包括陶瓷插芯和座体6，座体6用于固定陶瓷插芯。如图7所示，座体6设置有若干卡口7用于与内壳体3前端的限位块8配合防止陶瓷插芯组件2转动。该光学接口即陶瓷插芯的端口，光纤的端面位于陶瓷插芯的端口处以便进行光信号传输，通常光纤通过胶水固定在陶瓷插芯内。由于标准的需要陶瓷插芯组件2需要与弹簧9配合从而能够在内壳体3的内腔内前后移动，以便在陶瓷插芯与适配器34或通信设配接触时保持一定的压力，从而保证光纤通信的稳定，该限位块8与座体6的卡口7配合使陶瓷插芯组件2能够稳定地前后移动。
所述内壳体3的内部具有贯通的内腔10，该内腔10主要用于容纳陶瓷插芯组件2和弹簧9，并允许光纤穿入。所述陶瓷插芯组件2配置于所述内腔10并且所述光学接口从所述内腔10的前端伸出。所述内壳体3的外表面的主体上设置有承载部11，靠近所述内壳体3的尾部设置有凹槽部12，所述承载部11用于搭载所述接触部4，所述凹槽部12用于收纳导电片1的连接部5与电缆电连接时形成的所述结合部21。承载部11和凹槽部12在一定程度上也能够起到对到导电片1限制并固定的作用。
对于内壳体3，其本身可以是一个一体的壳体，但是为便于该内壳体3装配陶瓷插芯组件2，如图7和图8所示，内壳体3可分为两部分，分别前内壳体13和后内壳体14，由此内腔也分为前后两部分，前内壳体13的内腔主要用于容纳陶瓷插芯组件2，后内壳体14主要用于配置弹簧9。
后内壳体14的前部端面设置有伸出的并且可伸入到一部分前内壳体13的内腔10的筒状部15，筒状部15内设置有用于配置弹簧9的抵接部16。所述陶瓷插芯组件2设置于所述前内壳体的内腔10，所述弹簧9一端抵接到所述陶瓷插芯组件2的座体6，另一端收纳并抵接于筒状部15内的抵接部16。座体6同时在一定程度上被筒状部15的前部端面限制。
筒状部15的外表面两侧设置有卡块17，前内壳体13两侧设置有卡口18，前内壳体13的尾部主体还设置有允许前内壳体13的尾部产生弹性形变，使前内壳体13的尾部主体容易向外侧扩张的豁口19，通过所述卡块17与所述卡口18的配合可将所述前内壳体13插入所述后内壳体14的筒状部15并固定在一起，如此可将所述陶瓷插芯组件2和所述弹簧9限制在由所
述前内壳体13和所述后内壳体14连接形成的内腔内。
由于内壳体3分为两部分，为此前内壳体13上设置承载部11，后内壳体14上设置凹槽部12。承载部11可以设置成略微凸出于所在的前内壳体13的平面的凸出台，以便于搭载的导电片1的接触部4露出从而使接触部4与外部进行电接触。后内壳体14的主体的尾部设置有与所述凹槽部12连通的通过部20，所述通过部20用于允许电缆从后内壳体14的尾端进入所述凹槽部12，从而使包括电缆的整个连接器的尾部主体低于内壳体3的主体。可替换的是，凹槽部12的尾端呈开放状态，即该凹槽部12为从尾端向前延伸，尾端呈开放式的槽。
所述导电片1设置有两个并且配置在内壳体3的同侧即同一个面上。凹槽部12的数量与导电片1的数量对应。所述接触部4可配置于与所述导电片1主体相同的面上，或者如图12所示，所述导电片1设置有两个并且配置在内壳体3的同侧即同一个面上，所述接触部4与导电片1的主体垂直设置，如此两个导电片1的接触部4可分别配置于与所述导电片1主体相邻的侧面上，该接触部4可从外壳体22侧部的镂空部分露出与外部连通。
对于SC结构的光电复合光纤连接器，其外壳体22套设在内壳体3上并可前后移动，以便将光纤连接器从适配器34卸下，所述外壳体22设置有两个允许接触部4与外部连通的开口23。由于外壳体22需要能够前后移动，因此开口23的长度要大于接触部4的长度。如图10所示，该外壳体22在尾端完全覆盖内壳体3的凹槽部12。
对于导电片1固定在内壳体3上，除承载部11和凹槽部12通过轮廓边沿等限制外还可设置专门用于固定导电片1的固定部，具体地：
如图2所示，内壳体3用于配置所述导电片1的面上设置有卡柱24，所述导电片1的主体上设置有卡口25，通过所述卡柱24与所述卡口25的配合将所述导电片1固定于所述内壳体3。该卡柱24可以设置为靠近顶部的直径大于靠近内壳体3主体的直径，或者整个卡柱24的直径略大于卡口25，在相对于承载部11和凹槽部12的竖直方向上压下导电片1，通过过盈配合将导电片1固定在内壳体上。
如图3所示，可选的是，所述内壳体3上与配置所述导电片1相邻的侧面设置有卡接部26，相应的卡接部26的内壳体3的周围设置避让部。所述导电片1还设置有与所述导电片1的主体垂直的延伸部27，所述延伸部27设置有卡口28，在相对于承载部11和凹槽部12的竖直方向上压下导电片1，通过所述卡接部26与所述卡口28的配合将所述导电片1固定于所述内壳体3。
如图4和图9所示，可选的是，所述内壳体3配置有从两侧向内部延伸的卡槽部29，卡
槽部29由内壳体3的主体镂空而成，其主要对应连接部5以及连接部5与接触部4过渡的垂直于连接部5和接触部4的导电片1部分。该垂直于连接部5和接触部4的卡槽部29部分也可以由前内壳体13和后内壳体14的接缝处形成。位于与接触部4的前端对应的位置上可以设置第二卡槽部30，相应的接触部4的前端配置有勾状部31，该勾状部31与第二卡槽部30相对应。所述导电片1可从两侧插入所述卡槽部29并通过所述卡槽部29固定于所述内壳体3。同时，所述内壳体3上设置有卡块32，该卡块32可设置在凹槽部12内，所述导电片1的主体上设置有卡口33，在导电片1从侧部插入的过程中连接部5翘起，并在卡口33进入卡块32后通过自身的韧性回弹，如此通过所述卡块32与所述卡口33配合限制进入所述卡槽部29的所述导电片1，阻止导电片1从侧部轻易掉出。
在上述方案中，由于内壳体3上的承载部11和凹槽部12均相对于内壳体3的表面呈开放状态，所以导电片1均可从内壳体3的外侧向内壳体1的主体移动并通过固定部固定在内壳体3上。导电片1可预先与电缆进行固定，也可以在固定到内壳体3上后再进行固定。如图11所示，在光电复合光纤连接器的适配器34内设置金属导电压片35，该金属导电压片35具有弹性挤压部，该弹性挤压部与导电片1的接触部4进行接触从而实现电连接。如图13所示，通过部20整体可配置为一个向尾端延伸的用于搭载一小段电缆的承载台，在承载台配置光缆后，再通过的压接环36套入承载台部分，如此将位电缆固定在承载台上，然后再装入尾套37对承载台以及电缆进行包裹封闭。可将压接环36设置呈六边形，六边形的结构便于固定配置在承载台上的电缆。如图14所示，导电片1的主体也可以配置在内壳体3的两侧，而凹槽部12设置于与两个导电片1相邻的一侧，又或者如图15所示，导电片1的主体和凹槽部12均设置于内壳体3的两侧。
本申请同时提供了光电复合光纤连接器的另一种实施方式，如图16、图17、图18、图19、图20、图21和图22所示，所述光电复合光纤连接器包括：
导电片38，导电片38具有接触部39、连接部40和插入部41，接触部39用于与外部设备进行电接触，连接部40设置于所述接触部39和所述插入部41之间。导电片38可由一片铜片制成，并保证接触部39具有足够的接触面积，同时插入部41具有足够的与电缆进行焊接或压接的面积。接触部39和插入部41所处的面相互平行，即两者在不同的高度上，因此将导电片38弯折成型时自然形成一个连接两者的连接部40。外部设备可以为适配器、接续器或者电源等。
陶瓷插芯组件42，其具有光学接口，陶瓷插芯组件用于固定光纤。该部分与现有技术的
结构基本一致，具体地，陶瓷插芯组件42主要包括陶瓷插芯，座体和弹簧，座体固定在陶瓷插芯上，陶瓷插芯通过胶水固定光纤，光纤端部被固定在陶瓷插芯的端口处，该光学接口即陶瓷插芯的端口，光学接口用于与光设备进行通信。座体设置有若干卡口用于与前内壳体43的前端的限位块45配合防止陶瓷插芯组件转动。弹簧与座体配合使陶瓷插芯能够前后移动，以便在陶瓷插芯与适配器或通信设配接触时保持一定的压力，从而保证光纤通信的稳定。
前内壳体43和后内壳体44，前内壳体43和后内壳体44均配置有贯通的内腔46。陶瓷插芯组件42配置于前内壳体43的内腔46并且所述光学接口从前内壳体43的前端伸出，后内壳体44的前端设置有延伸部47，前内壳体43通过卡接部固定于所述延伸部47。具体地，延伸部47的主体为圆柱状，其外表面设置有凸起48，前内壳体43靠近尾部的部分设置有卡口49，如此延伸部47可伸入到前内壳体43的内腔46内，并通过卡口49与凸起48配合固定，同时前内壳体43上设置有允许其尾部产生一定弹性形变的豁口50，如此使前内壳体43更容易插入后内壳体44。延伸部47伸入至前内壳体43的内腔46的一部分，如此保留的前内壳体43靠近前端的内腔46的剩余部分容纳陶瓷插芯组件42，延伸部47内的内腔形成一个抵接台用于抵接弹簧，使弹簧抵接在延伸部47的内腔46内。前内壳体43和后内壳体44固定在一起后由于内腔46贯通，如此光电复合缆内的光纤可从后内壳体44的尾端插入并固定至陶瓷插芯，最终从前内壳体43的前端伸出。
如图23、图24、图25和图26所示，前内壳体43的表面设置有用于搭载导电片38的接触部39的承载部51。该承载部51可以是一个凸起的平台，也可以是与前内壳体43持平的面。后内壳体44设置有与导电片38的插入部41配合的插入腔52，该插入腔52与内腔46平行，靠近后内壳体44的尾部设置有与插入腔52连通的凹槽部53。位于前内壳体43和所述后内壳体44结合的接缝处设置有用于收纳连接部40的避让部54，避让部54将插入腔52与外部连通，并将插入腔52引导至承载部51。一个插入腔52和一个凹槽部53对应一个导电片38。
当导电片38的插入部41插入到插入腔52后，插入部41至少一部分从插入腔52进入凹槽部53，位于凹槽部53内的插入部41与电缆进行电连接，由于插入部41与电缆进行电连接时必然会形成凸起或结合部，如此该结合部即被收纳于凹槽部53内。当前内壳体43和后内壳体44结合后通过避让部54将导电片38的插入部41引导至承载部51上的接触部39。在前内壳体43的尾端和后内壳体44的前端(非延伸部47)紧密贴合时，该避让部54可以为设置在前内壳体43的尾端面或者后内壳体44的前端面的槽，或者前内壳体43的尾端面和后内壳体44的前端面均设置槽，以便容纳连接部40。避让部54也可以是在前内壳体43的尾端和后内
壳体44结合后，两者的结合处留有缝隙，即两者并未完全贴紧，该缝隙即为避让部。
后内壳体44的尾部设置有延长部55，延长部55设置有连接槽56，连接槽56从后内壳体44的尾部与凹槽部53连通，连接槽56用于收纳与凹槽部53内的插入部41电连接的电缆。在电缆位于凹槽部53内与插入部41电连接后，如图27所示，可通过套入金属固定套57将电缆固定在延长部55上。该固定套57可以为六边形或多边形，以便更容易套入同时适配位于延长部55上的电缆。最后再通过尾套58对延长部55进行包裹。
对于类似于SC接口的连接器，还包括外壳体59，外壳体59套设在由前内壳体和后内壳体结合后形成的内壳体上并可前后移动，外壳体59设置有允许接触部39与外部连通的开口60。该外壳体59可在上方封闭凹槽部53。
导电片38设置有两个并且导电片38的主体配置在前内壳体43和后内壳体44结合后形成的内壳体的同侧，接触部39可配置于与导电片38主体相同的面上，或者如图28所示，所述接触部39的从主体的前端向两侧延伸，从而使接触部39分别配置于与导电片38主体相邻的侧面，即位于内壳体的两侧。同时，也可以配置成将导电片38分别配置在内壳体的两侧，插入腔52和凹槽部53相应地配置在内壳体的两侧。
