 本发明的最佳实施方式
现结合附图，对本发明的较佳实施例作详细说明。
如图1-图4所示，本发明提供一种电源适配器的最佳实施例。
一种带lightning母座的电源适配器，参考图1，所述电源适配器包括。
主体1，所述主体1上设有作为电能输出口的lightning母座11以及适配器单元12，所述lightning母座11与适配器单元12电连接。
壳体2，所述壳体2上设有与lightning母座11连通的开口21，所述壳体2套设在主体1外部，并使得开口21与lightning母座11对应。
其中，所述适配器单元12能够直接或间接为lightning母座11提供电能，并通过所述lightning母座11向外输出电压和电流。
具体的，并参考图1，所述主体1为一电路板，所述电路板上设置有lightning母座11，所述lightning母座11作为电能输出口能够为外部终端设备供电。所述电路板上还设置有适配器单元12，所述lightning母座11与适配器单元12电连接，所述适配器单元12能够直接或间接为lightning母座11提供电能，以为外接终端设备充电。
进一步地，并参考图1，所述电源适配器还包括壳体2，所述壳体2上设置有与lightning母座11连通的开口21，所述主体1设置在壳体2内，并使得lightning母座11与开口21对应。
具体的，所述适配器单元12主要是用于将频率低的交流整流为直流，然后将直流转换成高频交流信号，然后通过变压整流成直流，以实现给外部终端设备充电。所述适配器单元12设置在所述壳体2内，所述开口21开设在壳体2的一侧面，所述lightning母座11与适配器单元12连接并朝向壳体2的开口21处，并与该开口21对应设置，主要用于与外部终端设备连接以为其供电。
参考图1和图2，本发明提供lightning母座11的两种设置方式。
方案一
参考图1，所述lightning母座11与适配器单元12连接后往壳体2侧面延伸并延伸至壳体2侧面的开口21处，并与该开口21位置对应。
具体的，当外部数据线插入lightning母座11时，所述外部数据线接口处的lightning公接口32伸入所述带lightning母座的电源适配器的lightning母座11，并通过lightning母座11与壳体2内的适配器单元12连接。
方案二
参考图2，所述壳体2上还设置有一个用于固定外部数据线接头的金属圈22，所述金属圈22设置在开口21靠外侧的端部，并与lightning母座11的端部对应。
具体的，当外部数据线插入lightning母座11时，所述外部数据线接口处的lightning公接口32伸入所述带lightning母座的电源适配器的lightning母座11，并通过lightning母座11与壳体2内的适配器单元12连接，进一步通过lightning母座11外侧的金属圈22固定，现有技术中，所述lightning母座11的外侧一般设置橡胶圈以使得lightning公接口32更加稳定的插入lightning母座11中，但是橡胶圈为软圈，当lightning公接口32插入lightning母座11中时，还是容易左右摇晃，本实施例通过在lightning母座11的外侧端部设置一金属圈22，其硬度较大，一方面，可进一步提高lightning公接口32在插入时的稳定性，另一方面，还可有效防止外部数据线在充电过程中，由于弯折而造成线体开裂，进一步有效防止了lightning母座11与线体断开。
进一步地，并参考图3，所述主体1上还设置有通信控制单元13以及适配器控制单元14，所述通信控制单元13分别与适配器控制单元14、适配器单元12及lightning母座11连接，在所述lightning母座11外接终端设备时，所述通信控制单元13通过lightning母座11与外接终端设备进行握手通信；所述适配器控制单元14在握手通信完成后通过lightning母座11与外接终端设备进行协议通信；所述适配器单元12在完成协议通信后且根据适配器控制单元14控制直接或间接为lightning母座11提供对应充电参数的电能，以为外接终端设备充电。
具体的，所述通信控制单元13的第二控制引脚与lightning母座11的第一通道引脚连接，所述通信控制单元13通过lightning母座11的第一通道引脚提供上电信号，且当lightning母座11外接终端设备时，进行握手通信。首先，通信控制单元13直接与终端设备进行握手通信，为实现适配器单元12对终端设备进行快充进行前期准备沟通；以及，在在握手通信完成后，在确认沟通成功符合要求后，适配器单元12在完成协议通信后且根据适配器控制单元14控制直接或间接为lightning母座11提供对应充电参数的电能，以为外接终端设备充电。
进一步地，所述适配器控制单元14的第一控制引脚与lightning母座11的第一通道引脚连接，所述通信控制单元13的握手引脚与lightning母座11的识别控制引脚连接，所述适配器单元12的电能输出端直接或间接与lightning母座11的电源引脚连接；其中，所述通信控制单元13在lightning母座11外接终端设备时，通过lightning母座11的识别控制引脚与外接终端设备进行握手通信；适配器控制单元14在握手通信完成后通过lightning母座11的第一通道引脚与外接终端设备进行协议通信；适配器单元12在完成协议通信后且根据适配器控制单元14控制直接或间接为lightning母座11的电源引脚提供对应充电参数的电能，以为外接终端设备充电。

优选地，并参考图4，所述适配器单元12通过适配器控制单元14为lightning母座11提供对应充电参数的电能，通过适配器控制单元14作为输出电能的调控，以提供最佳的电能输出操作，满足终端设备的充电要求。
其中，lightning母座11外接终端设备一般认为是通过数据线将lightning母座11与外接终端进行连接，数据线的一端为可以插入lightning母座11的Lightning公头，且另一端为可以插入外接终端的充电口的充电头；其中，适配单元的电能输出正极通过lightning母座11的电源引脚、Lightning公头的电源引脚、数据线的电源线和充电头的电能输出正极，与终端设备的电能输入正极连接。
其中，握手协议是指主要用来让客户端及服务器确认彼此的身份的一类网络协议，通信控制单元13在上电并检测到lightning母座11外接终端设备后，先通过通信控制单元13的握手模块与外接终端设备进行握手通沟通，判断是否属于可以进行协议快充的设备，或者判断是否属于已备案的设备。在一个实施例中，通信控制单元13包括第一芯片以及外围电路，通过额外设置一芯片IC实现通过lightning母座11与外接终端设备的交互，提高与外接终端设备进行高效性、准确性的通信，同时，在适配器的适配器控制单元14的基础上，增加第一芯片形成通信控制单元13的设计，一方面可以简化适配器关于适配器控制单元14的设计，另一方面实现模块化布局，提高电路结构的量产化，降低生产成本，实现功能分布化，特别是，将具有特定功能集成在第一芯片中，生产设计具有专用功能的芯片，避免芯片功能的浪费，降低成本。其中，通过第一芯片的多个引脚作为烧录引脚，为第一芯片进行软件烧录。优选地，握手模块通过第一芯片的一通讯引脚与lightning母座11的ID引脚连接，且第一芯片与lightning母座11之间设置一电阻。

方案一
所述I/O接口33为用于与外部设备连接的lightning接口。
