目前，光模块只支持对光信号进行传输，在光纤分布式系统中，往往需要额外对终端设备进行供电处理，这才能使得光纤分布式系统正常工作。如图1所示，光纤与电缆分离，第一光模块120与近端机的线路板140电连接，光纤分别与远端机100(如终端设备)和第一光模块120连接，远端机100还额外连接有电缆，该电缆对远端机100提供供电电源，近端机与远端机100之间能够通过光模块实现光传输，但该方案既增加了操作的复杂度，又增加了终端成本。
基于此，本申请提供了一种光模块及光信号系统，光模块包括第一壳体、正极连接块和负极连接块，其中，第一壳体设置有用于插接光电混合缆接头的空间，该空间内设置有用于进行光传输的光器件；正极连接块设置有第一对接点和第三对接点，该第一对接点处于空间内，该第三对接点外露于光模块，该第一对接点用于与设置有导电端的光电混合缆接头进行电连接，该第三对接点用于与设置有导电接口的线路板进行电连接；负极连接块，设置有第二对接点和第三对接点，该第二对接点处于该空间内，该第四对接点外露于光模块，第二对接点用于与设置有导电端的光电混合缆接头进行电连接，该第四对接点用于与设置有导电接口的线路板进行电连接，即是说，当光电混合缆接头插入到光模块中时，光模块中的光器件可以与光电混合缆接头中的光纤进行对接，以实现光模块中的光器件对光电混合缆接头进行 光传输，同时正极连接块的第一对接点以及负极连接块的第二对接点可以与光电混合缆接头的导电端进行电连接，以及该正极连接块的第三对接点以及负极连接块的第四对接点可以与线路板的导电接口进行电连接，以实现线路板中的电源通过光模块对光电混合缆接头进行电传输，因此，本申请实施例提供的方案能够通过一次插接操作同时实现光传输和电传输，降低操作复杂度。
下面结合附图，对本申请实施例作进一步阐述。
参照图2，图2是本申请一个实施例提供的光模块的结构示意图，为了便于描述光模块的结构原理，图2中配以光电混合缆接头111进行说明。该光模块包括第一壳体129、正极连接块122和负极连接块123。
第一壳体129，设置有用于插接光电混合缆接头111的空间，空间内设置有用于进行光传输的光器件128；
正极连接块122，设置有第一对接点和第三对接点，第一对接点处于空间内，第三对接点外露于光模块，第一对接点用于与设置有导电端的光电混合缆接头111进行电连接，第三对接点用于与设置有导电接口的线路板进行电连接；
负极连接块123，设置有第二对接点和第四对接点，第二对接点处于空间内，第四对接点外露于光模块，第二对接点用于与设置有导电端的光电混合缆接头111进行电连接，第四对接点用于与设置有导电接口的线路板进行电连接。
在本实施例中，当光电混合缆接头111插入到光模块中时，光模块中的光器件128可以与光电混合缆接头111中的光纤进行对接，以实现光模块中的光器件128对光电混合缆接头111进行光传输，同时正极连接块122的第一对接点以及负极连接块123的第二对接点可以与光电混合缆接头111的导电端进行电连接，以及该正极连接块122的第三对接点以及负极连接块123的第四对接点可以与线路板的导电接口进行电连接，以实现线路板中的电源通过光模块对光电混合缆接头111进行电传输，因此，本申请实施例提供的方案能够通过一次插接操作同时实现光传输和电传输，降低操作复杂度。
可以理解的是，该线路板可以提供供电电源，比如恒压源电源，以便于线路板通过光模块对光电混合缆接头111进行电传输。
可以理解的是，正极连接块122和负极连接块123均是导体，比如金属等可以用于传输电信号的导体，在此不做具体限制。
需要说明的是，第一对接点和第三对接点可以相对设置于正极连接块122上，第二对接点和第四对接点可以相对设置于负极连接块123上。比如，第一对接点和第三对接点分别设置在正极连接块122两端，第二对接点和第四对接点分别设置在负极连接块123的两端，在此不做具体限制。
在一实施例中，正极连接块122包括伸进第一壳体129所设置的用于插接光电混合缆接头111的空间的第一弯折部135，该第一弯折部135设置有第一对接点，而负极连接块123包括伸进第一壳体129所设置的用于插接光电混合缆接头111的空间的第二弯折部(图中未示出)，该第二弯折部设置有第二对接点，该第一弯折部可以使得第一对接点伸入该空间内，第二弯折部可以使得第二对接点处于该空间内，以使正极连接块122的第一对接点以及负极连接块123的第二对接点均可以与光电混合缆接头111的导电端进行电连接，当正极连接块122的第二对接点以及负极连接块123的第四对接点与线路板的导电接口进行电连接时，线 路板通过光模块对光电混合缆接头111进行电传输。
在一实施例中，光模块还包括电极载体126，该电极载体126安装于第一壳体129内，该电极载体126设置有第一安装槽131和第二安装槽132，正极连接块122安装于第一安装槽131中，负极连接块123安装于第二安装槽132中，这样，正极连接块122和负极连接块123在周转过程中不会发生移位，保证产品结构的稳定性。而且，当光电混合缆接头111插接到光模块的第一壳体129中时，正极连接块122的第一对接点可以穿过该第一安装槽131与光电混合缆接头111的导电端进行电连接，负极连接块123的第二对接点可以穿过该第二安装槽132与光电混合缆接头111的导电端进行电连接，以实现光模块与光电混合缆接头111之间的电传输。
可以理解的是，正极连接块122和负极连接块123均可以有不同的实施方式。例如，正极连接块122可以固定安装于第一安装槽131中，负极连接块123可以固定安装于第二安装槽132中；或者，正极连接块122可以滑动安装于第一安装槽131中，负极连接块123可以滑动安装于第二安装槽132中，本实施例对此不做具体限制。
基于上述实施例，当正极连接块122滑动安装于第一安装槽131中，负极连接块123滑动安装于第二安装槽132中时，正极连接块122还包括第一主体137和第一挡片136，负极连接块123还包括第二主体138和第二挡片(图中未示出)，该第一挡片136分别连接第一弯折部135和第一主体137，该第二挡片分别连接第二弯折部和第二主体138，并且光模块还包括第一弹性部件124和第二弹性部件125，该第一弹性部件124安装于第一安装槽131并与第一挡片136抵接，该第二弹性部件125安装于第二安装槽132并与第二挡片抵接，当外力作用在正极连接块122上时，通过第一挡片136对第一弹性部件124进行压缩或者还原，以促使正极连接块122在第一安装槽131中滑动，同样地，当外力作用在负极连接块123上时，通过第二挡片对第二弹性部件125进行压缩或者还原，以促使负极连接块123在第二安装槽132中滑动，因此，正极连接块122和负极连接块123可以通过外力作用和弹性部件自身的形变进行滑动。在一些实施例中，当光电混合缆接头111插入到光模块中时，光电混合缆接头111产生的推力同时作用在正极连接块122和负极连接块123上，以使正极连接块122的第一挡片136对第一弹性部件124进行压缩，负极连接块123的第二挡片对第二弹性部件125进行压缩，从而推动正极连接块122在第一安装槽131中滑动，以及推动负极连接块123在第二安装槽132中滑动，直至正极连接块122的第三对接点和负极连接块123的第四对接点均与线路板的导电接口电连接；当光电混合缆接头111从光模块中拔出时，光电混合缆接头111所产生的推力消失，第一弹性部件124和第二弹性部件125均缓慢恢复原形，在第一弹性部件124和第二弹性部件125的弹力作用下，正极连接块122在第一安装槽131中滑动，负极连接块123在第二安装槽132中滑动，正极连接块122的第三对接点和负极连接块123的第四对接点均远离线路板的导电接口，从而避免第三对接点和第四对接点分别与线路板的导电接口误接触，本实施例对此不做具体限制。
需要说明的是，第一弹性部件124和第二弹性部件125可以是螺旋弹簧、压缩弹簧、短弹簧或者其他能够压缩的弹性部件，在此不做具体限制。
还需要说明的是，光模块还可以包括多个绝缘板121，该绝缘板121覆盖在滑块载体上，用于保护正极连接块122和负极连接块123，并且该绝缘板121的数量不限，可以是一块或者多块，在此不做具体限制。还需要说明的是，绝缘板121可以由塑料或者橡胶等绝缘材料 制成，在此不做具体限制。
在一实施例中，正极连接块122还设置有第一斜面133，而第三对接点设置于第一斜面133，同样地，负极连接块123还设置有第二斜面134，而第四对接点设置于第二斜面134，并且第一斜面133和第二斜面134均外露于光模块，第一斜面133上的第三对接点和第二斜面134上的第四对接点均可以与线路板上的导电接口电连接。
需要说明的是，如图8所示，线路板140的第一导电接口可以设置有用于与第三对接点弹性连接的第一弹片141，第二导电接口可以设置有用于与第四对接点弹性连接的第二弹片142。在一实施例中，如图6和图7所示，当光电混合缆接头插接到光模块中时，光电混合缆接头可以推动正极连接块122和负极连接块123，使正极连接块122的第一斜面133上的第三对接点与线路板140上的第一弹片141弹性连接，负极连接块123的第二斜面134上的第四对接点与线路板140上的第二弹片142弹性连接，从而实现光电混合缆与光模块之间的电连接，并且弹片这种设计结构可以增强弹片与对接点之间的相互作用力，使得弹片和对接点接触稳固，本申请实施例对此不做具体限制。
可以理解的是，第一弹片和第二弹片均为导体，比如金属等可以用于传输电信号的导体，在此不做具体限制。
在另一实施例中，如图3所示，正极连接块122还设置有第一凸台151，而第三对接点设置于第一凸台151，同样地，负极连接块123还设置有第二凸台152，而第四对接点设置于第二凸台152，并且第一凸台151和第二凸台152均外露于光模块，第一凸台151上的第三对接点和第二凸台152上的第四对接点均可以与线路板上的导电接口电连接。

此外，参考图4和图5，本申请的另一个实施例还提供了一种光信号系统，该光信号系统包括近端机、远端机100和光电混合缆112，而近端机和远端机100均插接有如上述任一实施例的光模块，其中，近端机插接的光模块为第一光模块120，远端机100插接的光模块为第二光模块(图中未示出)，光电混合线缆包括第一光电混合缆接头(图中未示出)和第二光电混合缆接头(图中未示出)，并且第一光电混合缆接头插接于近端机中的第一光模块120，第二光电混合缆接头插接于远端机100中的第二光模块。该光信号系统具有由上述任一实施例中的光模块所带来的有益效果，例如，当第一光电混合缆接头插入到第一光模块120中，第二光电混合缆接头插接于第二光模块时，第一光模块120中的光器件可以与第一光电 混合缆接头中的光纤进行对接，第二光模块中的光器件可以与第二光电混合缆接头中的光纤进行对接，因此，近端机和远端机100之间可以通过第一光模块120、第一电混合缆接头、第二光模块和第二电混合缆接头实现光传输，因此，本申请实施例提供的方案能够通过一次插接操作同时实现光传输。
需要说明的是，光电混合缆112包括光纤和电缆，光电混合缆112的两端设置有第一光电混合缆接头和第二光电混合缆接头，其中，光纤通常由陶瓷或者塑料等绝缘材料制成，在此不做具体限制。
需要说明的是，远端机100可以有多个，并且，远端机100的数量、光电混合缆112的数量、第一光模块120的数量和第二光模块的数量一一对应，在此不做具体限制。
在一实施例中，参考图6和图7，第一光模块和第二光模块均包括正极连接块122和负极连接块123，并且正极连接块122设置有第一对接点(图中未示出)和第三对接点，负极连接块123设置有第二对接点(图中未示出)和第四对接点，而且近端机和远端机均包括线路板(图中未示出)，线路板设置有用于与第三对接点电连接的第一导电接口和用于与第四对接点电连接的第二导电接口，第一光电混合缆接头和第二光电混合缆接头均设置有用于与第一对接点电连接的第一导电端和用于与第二对接点电连接的第二导电端，因此，近端机的线路板和第一光模块之间以及远端机的线路板和第二光模块之间均可以通过第一导电接口与第三对接点的电连接以及第二导电接口与第四对接点的电连接而传输电信号，当第一光电混合缆接头插接于第一光模块，第二光电混合缆接头插接于第二光模块，第一光模块和第一光电混合缆接头之间以及第二光模块和第二光电混合缆接头之间均可以通过正极连接块122的第一对接点与第一导电端的电连接以及负极连接块123的第二对接点与第二导电端的电连接而传输电信号，即是说，第一光模块和第二光模块可以通过光电混合缆进行电连接，因此，近端机的线路板中的电源可以通过第一光模块、光电混合缆和第二光模块对远端机的线路板进行供电，解决了额外对终端设备进行供电处理的问题，而且降低了操作的复杂度，同时减少了终端成本。又因为，当第一光电混合缆接头插接于第一光模块，第二光电混合缆接头插接于第二光模块，第一光模块中的光信号可以通过光电混合缆中的光纤传输到第二光模块，因此，本申请实施例中的近端机与远端机之间可以通过一次插接操作同时实现光传输和电传输，降低操作复杂度。

在一实施例中，如图8所示，若第一导电接口设置有第一弹片141，第二导电接口设置有第二弹片142时，正极连接块还可以设置有第一斜面，而第三对接点设置于第一斜面，负极连接块还可以设置有第二斜面，而第四对接点设置于第二斜面，并且第一斜面和第二斜面均外露于光模块，当第一光电混合缆接头插接到第一光模块或者第二光电混合缆接头插接到第二光模块时，第一光电混合缆接头或者第二光电混合缆接头可以推动正极连接块和负极连接块，使正极连接块的第一斜面上的第三对接点与线路板140上的第一弹片141弹性连接，负极连接块的第二斜面上的第四对接点与线路板140上的第二弹片142弹性连接，从而实现光电混合缆与光模块之间的电连接，并且弹片这种设计结构可以增强弹片与对接点之间的相 互作用力，使得弹片和对接点接触稳固，本申请实施例对此不做具体限制。
在另一实施例中，如图9所示，若第一导电接口设置有第一焊盘，第二导电接口设置有第二焊盘时，正极连接块还设置有第一凸台，而第三对接点153设置于第一凸台，负极连接块还设置有第二凸台，而第四对接点154设置于第二凸台，并且第一凸台和第二凸台均外露于光模块，当第一光电混合缆接头插接到第一光模块或者第二光电混合缆接头插接到第二光模块时，第一光电混合缆接头或者第二光电混合缆接头可以推动正极连接块和负极连接块，使正极连接块的第一凸台上的第三对接点153与线路板140上的第一焊盘连接，负极连接块的第二凸台上的第四对接点154与线路板140上的第二焊盘连接，从而实现光电混合缆与光模块之间的电连接，本申请实施例对此不做具体限制。
在一实施例中，如图10所示，近端机的线路板和远端机的线路板(图中未示出)均还设置有保护笼130，保护笼130设置有用于避让第一导电接口的第一避让位和用于避让第二导电接口的第二避让位，当第一光模块或者第二光模块插接到保护笼130中，第三对接点正对着第一避让位，第四对接点正对着第二避让位，因此，线路板上的第一导电接口可以穿过第一避让位与光模块上的第三对接点进行电连接，第二导电接口可以穿过第二避让位与光模块上的第四对接点进行电连接，因此，本申请实施例既可以实现线路板与光模块之间的电传输，又可以保护光模块。
需要说明的是，保护笼130可以是金属笼，或者是其他可以保护光模块的装置，在此不做具体限制。
在一实施例中，如图6、图8和图10所示，当正极连接块122设置有第一斜面，而第三对接点设置于第一斜面，负极连接块123还可以设置有第二斜面，而第四对接点设置于第二斜面，并且第一斜面和第二斜面均外露于光模块时，将光模块插接到保护笼130中，当光电混合缆接头插接到该光模块中时，光电混合缆接头可以推动正极连接块122和负极连接块123，使正极连接块122的第一斜面133上的第三对接点穿过保护笼130的第一避让位与线路板140上的第一弹片141弹性连接，负极连接块123的第二斜面134上的第四对接点穿过保护笼130的第二避让位与线路板140上的第二弹片142弹性连接，因此，本申请实施例既可以实现线路板与光模块之间的电传输，又可以保护光模块。

在一实施例中，如图12和图13所示，第一光电混合缆接头和第二光电混合缆接头均设置有用于与第一对接点电连接的第一导电端113和用于与第二对接点电连接的第二导电端114，并且第一光电混合缆接头和第二光电混合缆接头均还设置有第一电源接口155和第二电源接口156，第一电源接口155与第一导电端113电连接，第二电源接口156与第二导电端 114电连接。
