其中，充电器1，包括：Type-A母座11、PD充电处理单元12、非PD充电处理单元13、数据线匹配单元14以及第一切换单元15。具体的，Type-A母座11包括第一通信引脚111，第一通信引脚111与第一切换单元15的第一端连接，第一切换单元15的第二端与PD充电处理单元12连接，第一切换单元15的第三端与数据线匹配单元14连接，第一切换单元15的第四端与非PD充电处理单元13连接。
其中，在充电器1通过数据线与待充电设备连接的情况下，若所述数据线为第一数据线且所述待充电设备为第一待充电设备，第一切换单元15的第 一端与第一切换单元15的第二端连通，且第一切换单元15的第一端与第一切换单元15的第三端和第四端均断开；或，

其中，数据线匹配单元14基于经第一通信引脚111传输的匹配信号确定充电器1与所述数据线匹配时，所述数据线为第一数据线，且数据线匹配单元14基于经第一通信引脚111传输的匹配信号确定所述待充电设备与充电器1之间进行PD协议通信时，所述待充电设备为第一待充电设备；数据线匹配单元14基于经第一通信引脚111传输的匹配信号确定充电器1与所述数据线不匹配时，所述数据线为第二数据线，且数据线匹配单元14基于经第一通信引脚111传输的匹配信号确定所述待充电设备与所述充电器1之间进行非PD协议通信时，所述待充电设备为第二待充电设备。
在具体实施中，上述第一数据线为与充电器1匹配的数据线，其具体可以是如图1和图4中所示数据线2。
需要说明的是，在同一时间，第一切换单元15的第一端仅与其第二端、第三端和第四端中的一个连接。另外，在初始状态下(即充电器1未连接电源或者未连接数据线的情况下)，第一切换单元15的第一端与第三端连通，即连通数据线匹配单元14和第一通信引脚111，以使数据线匹配单元14根据第一通信引脚111上传输的信号确定充电器1是否通过第一数据线与第一待充电设备连接。具体的，在第一切换单元15经第一通信引脚111获取到的第一匹配信号符合第一预设条件的情况下，第一切换单元15的第一端与第一切换单元15的第二端连通；在第一切换单元15经第一通信引脚111获取到的第一匹配信号符合第二预设条件的情况下，第一切换单元15的第一端与第一切换单元15的第四端连通，所述第一匹配信号从待充电设备或者与充电器1匹配的数据线2获取。
在应用中，该数据线匹配单元14用于识别与充电器1连接的数据线是否为与充电器1匹配的第一数据线，在匹配成功的情况下，则可以将第一通信 引脚111连接至非PD充电处理单元13或者PD充电处理单元12，并根据该非PD充电处理单元13或者PD充电处理单元12上接收的通信信息确定待充电设备选择PD通信通道或者非PD通信通道，从而连通待充电设备支持的的该通信通道。
另外，上述非PD充电处理单元13可以是任意非PD通信协议的充电处理单元，例如：数据负信号(DataMinus，DM)充电通信和数据正信号(Data Positive，DP)充电通信的充电处理单元，此时上述第一通信引脚可以是D+引脚或者D-引脚。当然，在具体实施中，上述非PD充电处理单元13还可以是现有的其他非PD通信协议的充电处理单元或者今后可能出现的非PD通信协议的充电处理单元，在此不作具体限定。
另外，在具体实施中，上述第一预设条件可以包括：
第一通信引脚111获取到第一匹配信号或者所述第一匹配信号与所述数据线匹配单元14中预存的第一预设匹配信号匹配成功；
所述充电器1连接的待充电设备与所述充电器1之间进行PD协议通信。
其中，在第一匹配信号由数据线发送的情况下，上述第一通信引脚111获取到第一匹配信号或者所述第一匹配信号与所述数据线匹配单元14中预存的匹配信号匹配成功，可以表示：该数据线为与充电器1匹配的第一数据线。
在第一匹配信号由待充电设备发送的情况下，上述第一通信引脚111获取到第一匹配信号或者所述第一匹配信号与所述数据线匹配单元14中预存的匹配信号匹配成功，可以表示：该待充电设备为与充电器1匹配的第一待充电设备。
另外，上述所述充电器1连接的待充电设备与所述充电器1之间进行PD协议通信，可以表示：待充电设备为支持PD快速充电功能的设备，且选择PD协议通信进行PD快速充电。
在具体实施中，上述第二预设条件包括以下至少一项：
在充电器1连接电源和数据线后的预设时间内，第一通信引脚111未获取到所述第一匹配信号；
第一通信引脚111获取到的匹配信号与数据线匹配单元14中预存的第一预设匹配信号不匹配，或者与数据线匹配单元14中预存的第二预设匹配信号 匹配；
充电器1连接的待充电设备不支持PD协议通信；
充电器连接1的待充电设备与充电器1之间进行非PD协议通信。
其中，上述预设时间可以是3秒、5秒等，用于增加接收第一匹配信号的时延，能够弥补待充电设备或者数据线在信号传输、进行识别和配置等过程中增加第一通信引脚111接收到第一匹配信号的时间。
另外，在第一匹配信号由数据线发送的情况下，上述在充电器1连接电源和数据线后的预设时间内，第一通信引脚111未获取到所述第一匹配信号，可以表示：该数据线为常规的第二数据线，从而不对充电器1发送第一匹配信号；上述第一通信引脚111获取到的匹配信号与数据线匹配单元14中预存的第一预设匹配信号不匹配，或者与数据线匹配单元14中预存的第二预设匹配信号匹配，可以表示：该数据线为与充电器1不匹配的第二数据线。
在第一匹配信号由待充电设备发送的情况下，上述在充电器1连接电源和数据线后的预设时间内，第一通信引脚111未获取到所述第一匹配信号，可以表示：该待充电设备为不支持非PD快速充电的第二待充电设备，此时充电设备可以对该第二待充电设备进行常规充电，该常规充电的过程与现有技术中的常规充电过程相同，在此不再赘述；另外，上述第一通信引脚111获取到的匹配信号与数据线匹配单元14中预存的第一预设匹配信号不匹配，或者与数据线匹配单元14中预存的第二预设匹配信号匹配，可以表示：该待充电设备为支持非PD快速充电，且选择非PD快速充电功能进行充电的第二待充电设备，其中，第一预设匹配信号可以是第二待充电设备选择非PD快速充电功能时的PD充电信号，第二预设匹配信号可以是待充电设备选择非PD快速充电功能时的非PD充电信号。
需要说明的是，若上述第一通信引脚可以是D+引脚和D-引脚中的一个，在充电器1上连接的数据线为与其不匹配的第二数据线的情况下，第一切换单元15的第一端与第一切换单元15的第四端连通，且D+引脚和D-引脚中的另一个与非PD充电处理单元13连接。
在具体实施中，上述第一匹配信号和第二匹配信号可以是数字信号，例如：在充电器1连接电源，且通过第一数据线连接待充电设备的情况下，数 据线匹配单元14生成第二匹配信号，并通过与其连接的第一通信引脚111以及第一数据线上的第三通信引脚211等将该第二匹配信号传递至第一数据线上的充电器匹配单元24或者通过第一数据线传递至待充电设备，充电器匹配单元24或者待充电设备响应于该第二匹配信号，生成第一匹配信号，并将该第一匹配信号通过第一通信引脚111传递至数据线匹配单元14，则数据线匹配单元14在获取到该第一匹配信号时确定充电器1上连接的数据线为与其匹配的第一数据线或者确定上述第一待充电设备选择PD快速充电功能，从而将第一切换单元15的第一端与第一切换单元15的第二端连通。
另外，上述第一匹配信号和第二匹配信号还可以是模拟信号，且第一切换单元15可以根据该模拟信号进行切换。

其中，在数据线2插入充电器的情况下，所述第二D+引脚和所述第二D－引脚与所述充电器中的非PD充电处理单元13连通。
本实施方式中，非PD充电处理单元13为D+/D－通信协议的充电处理单元，且通过第二处理模块12对D+走线和D－走线中的一个的功能进行切换，在其与第一CC引脚连接时，其作为CC通信走线；在其与第四通信引脚连接时，其作为DP/DM通信走线，从而避免了在Type-A公头21中增加CC引脚，并避免了在线缆23中增加CC走线，简化了数据线的走线结构，并增加了Type-A公头21的适用性。
需要说明的是，在实际应用中，Type-A公头21的结构和各个引脚的分布位置与如图1、图2以及图4所示Type-A母座11的结构以及各个引脚的分布位置相对应，在此不再赘述，相应的，Type-A公头21中可以包括VBUS引脚、GND引脚、D+引脚和D－引脚，且线缆23中也相应的包括VBUS走线、GND走线、D+走线和D－走线，且Type-C接口22中也相应的包括VBUS引脚、GND引脚、D+引脚和D－引脚，且VBUS走线的两端分别连接Type-A公头21中的VBUS引脚和Type-C接口22中的VBUS引脚，GND走线的两端分别连接Type-A公头21中的GND引脚和Type-C接口22中的GND引脚，D+走线的两端分别连接Type-A公头21中的D+引脚和Type-C接口22中的D+引脚，D－走线的两端分别连接Type-A公头21中的D－引脚和Type-C接口22中的D－引脚。
例如：该Type-A公头21设置有GND引脚、D+引脚、D－引脚以及 VBUS引脚，且上述第一通信引脚和第三通信引脚为D+引脚的情况下，在Type-A公头21插入Type-A母座11的情况下，Type-A公头21中的各个引脚与Type-A母座11中的各个引脚一一对应连接，具体对应连接关系如下表1所示：
