第一实施例：磁吸自由空间光电混合阴性连接器，为方便描述，本申请一些地方简称为阴性连接器。
请参照图2、图3，本阴性连接器10包括：第一绝缘基体11，其前端形成有插接腔14；固设于所述插接腔14的背部的导电针13和第一光通信模块15；设于所述第一绝缘基体11的、用于在插接前通过磁场自动将所述阴性连接器10和相应的阳性连接器40(见图4和图5)对准并在插接后通过磁场自动保持插接状态的第一对准及保持机构12；其中，所述第一光通信模块15包括：用于承载光纤的第一光纤连接器151；以及设于所述第一光纤连接器151的出光端的、用于对从所述阴性连接器10输往所述阳性连接器40的光束做扩大处理的第一透镜152，所述第一透镜152的位置被配置为：在所述插接状态，所述第一透镜152和所述阳性连接器40的第二透镜452(见图5)之间具有一定间距，如图1中的D。

其中，电触点43采用导电柱构造，电触点43与第二绝缘基体41、第二光纤连接器451与第二绝缘基体41可以用胶水、焊接或者机械结构固定在一起。光纤可使用热固化胶353ND或紫外固化胶固定在第二光纤连接器451，端面需要进行研磨抛光、切割。光纤可以是玻璃光纤或者塑料光纤。
如图5所示，所述阳性连接器40还包括从不同的位置配置于所述第二透镜452和所述第二光纤连接器451的、用于使所述第二透镜452和所述第二光纤连接器451对准的多个第二定位杆46。第二透镜452的前端还设有用于与前述引导部17(见图3)配合、引导所述第一透镜152与所述第二透镜452精确对准的引导配合部44，本实施例中，引导配合部44具体实施为从口部到底部直径逐渐减小的凹部。
如图5所示，本实施例中，所述第二对准及保持机构47为两个磁体，两个磁体被配置在所述第二绝缘基体41的前端对应所述插接凸部42的周围。

上述磁吸自由空间光电混合连接器至少具有以下优点：
1、既能传输光信号，又能传输电信号。
2、阴性连接器10和阳性连接器40之间通过自由空间光连接，且配置了用于将传输给对方的光束扩大的透镜，使得光路对尺寸公差的容忍度以及对污染物的容忍度较高，从而使得连接器具有加工良品率高、可靠性高的特点。
3、设置有利用磁场作用的对准及保持机构，在插接前自动将阴性连接器10和相应的阳性连接器40对准，在插接后自动保持插接状态。因此不但具有插接、分离方便的特点，而且能够避免由于插接腔14和插接凸部42配合松动导致的信号不稳定现象。
4、设置有引导部17和引导配合部44，实现了插接过程中，自动 引导阳性连接器40的透镜和阴性连接器10的透镜精确对准。
上述通过具体实施例对本发明进行了详细的说明，这些详细的说明仅仅限于帮助本领域技术人员理解本发明的内容，并不能理解为对本发明保护范围的限制。本领域技术人员在本发明构思下对上述方案进行的各种润饰、等效变换等均应包含在本发明的保护范围内。
