下面参照图1-图9详细描述根据本发明实施例的电源接口100。需要说明的是，电源接口100可以为用于充电或数据传输的接口，其可以设在手机、平板电脑、笔记本电脑或其他具有可充电功能的移动终端，电源接口100可以与相应的电源适配器电连接以实现电信号、数据信号的通信连接。
如图1-图9所示，根据本发明实施例的电源接口100，包括：主体部110、数据pin脚120和电源pin脚130。
具体而言，主体部110适于与电路板连接，数据pin脚120为间隔开的多个且与主体部110连接。电源pin脚130可以为间隔开的多个且与主体部110连接。电源pin脚130和数据pin脚120间隔排布。电源pin脚130包括导电部130a和与导电部130a相连的绝缘部130b，导电部130a和绝缘部130b在所述电源pin脚130的宽度方向(如图9所示的左右方向)上排布。
需要说明的是，电源接口100可以设在移动终端上，移动终端(例如手机、平板电脑、笔记本电脑等)的内部可以设有电池，外部电源可以通过电源接口100对电池进行充电。电源接口100可以适用于具有快速充电功能的电源适配器，也适用于普通电源适配器。这里，快速充电可以指充电电流大于2.5A的充电状态或者额定输出功率不小于15W的充电状态；普通充电可以指充电电流小于等于2.5A的充电状态或者额定输出功率小于15W的充电状态。也就是说，当利用具有快速充电功能的电源适配器给电源接口100充电时，充电电流大于等于2.5A或者额定输出功率不小于15W的充电状态；当利用普通电源适配器给电源接口100充电时，充电电流小于2.5A或者额定输出功率小于15W的充电状态。
为了使电源接口100、与电源接口100相适配的电源适配器标准化，需使电源接口100的尺寸满足标准接口的设计要求。例如，pin脚个数为24的电源接口100，其设计要求的 宽度(电源接口100的左右方向上的宽度，如图1所示的左右方向)为a，为了使本实施例中的电源接口100满足设计标准，本实施例中的电源接口100的宽度(电源接口100的左右方向上的宽度，如图1所示的左右方向)也为a。为使电源pin脚130能够在有限的空间内承载较大的充电电流，可以将24个pin脚中的部分pin脚省去，绝缘部130b填充在被省略的pin脚的位置处。
根据本发明实施例的电源接口100，通过将电源pin脚130的结构设计成导电部130a和绝缘部130b的结构，从而可以使电源接口100适用于不同的电源适配器，进而可以扩大电源接口100的适用范围，提升电源接口100的使用性能。
根据本发明的一个实施例，多个电源pin脚130中的至少一个包括拓宽段132，绝缘部130b和部分导电部130a位于拓宽段132上，导电部130a的横截面积大于数据pin脚120的横截面积以增加电源pin脚130的电流载荷量。由此，通过在电源pin脚130上设置拓宽段132，可以增大电源pin脚130的电流载荷量，从而可以提高电流的传输速度，使电源接口100具有快速充电的功能，进而可以提升电池的充电效率。为进一步提高电源pin脚130的承载电流的能力，根据本发明的一个实施例，导电部130a的长度(这里的长度是指如图2所示的前后方向上的长度)大于绝缘部130b的长度(这里的长度是指如图2所示的前后方向上的长度)。
根据本发明的一个实施例，导电部130a的位于拓宽段132上的横截面积为S，S≥0.09805mm2。经过实验验证，当S≥0.09805mm2时，电源pin脚130的电流载荷量至少为10A,由此可以通过提升电源pin脚130的电流载荷量来提高充电效率。经过进一步的试验验证，当S＝0.13125mm2时，电源pin脚130的电流载荷量为12A或以上，由此可以提升充电效率。。
根据本发明的一个实施例，电源pin脚130的厚度为D，D满足：0.1mm≤D≤0.3mm。经过实验验证，当0.1mm≤D≤0.3mm m时，电源pin脚130的电流载荷量至少为10A,由此可以通过提升电源pin脚130的电流载荷量来提高充电效率。经过进一步的试验验证，当D＝0.25mm时，可以大幅提升电源pin脚130的电流载荷量，电源pin脚130的电流载荷量为12A或以上，从而可以提升充电效率。
根据本发明的一个实施例，如图6、图10所示，在所述电源pin脚130的宽度方向(如图6、图10所示的左右方向)上，所述接触面的宽度为W，所述W满足：0.24mm≤W≤0.32mm。经过实验验证，当0.24mm≤W≤0.32mm时，电源pin脚130的电流载荷量至少为10A,由此可以通过提升电源pin脚130的电流载荷量来提高充电效率。经过进一步的试验验证，当W＝0.25mm时，可以大幅提升电源pin脚130的电流载荷量，电源pin脚130的电流载荷量为12A或以上，从而可以提升充电效率。
根据本发明的一个实施例，如图2所示，拓宽段132可以位于电源pin脚130的中部。 由此，可以优化多个电源pin脚130和多个数据pin脚120的布局，充分利用电源接口100的空间，从而可以提高电源接口100的结构紧凑程度和合理性。
根据本发明的一个实施例，导电部130a的位于拓宽段132的部位设有凹陷部133。需要说明的是，当电源接口100进行快速充电时，具有拓宽段132的电源pin脚130可以用于承载较大的充电电流；当电源接口100进行普通充电时，拓宽段132上的凹陷部133可以避免电源pin脚130与电源适配器上的对应pin脚接触。由此，可以使本实施例中的电源接口100适用于不同的电源适配器。例如，当电源接口100进行快速充电时，电源接口100可以与相应的具有快速充电功能的电源适配器电连接；当电源接口100进行普通充电时，电源接口100可以与相应的普通电源适配器电连接。这里，需要说明的是，快速充电可以指充电电流大于等于2.5A的充电状态；普通充电可以指充电电流小于2.5A的充电状态。
进一步地，为提高电源接口100的使用稳定性，凹陷部133内可以填充有绝缘部130b。由此，当电源接口100进行普通充电时，绝缘部130b可以有效地将电源pin脚130电源适配器上的对应pin脚间隔开，避免拓宽段132对电源适配器上的pin脚产生充电干扰，从而可以提升电源接口100对普通充电电源适配器适应能力，提升电源接口100在普通充电状态下的稳定性。
根据本发明的一些实施例，如图10所示，凹陷部133可以为一个，一个凹陷部133位于拓宽段132的第一侧壁134上，第一侧壁134适于与导电件电连接。需要说明的是，当电源接口100与电源适配器电连接时，电源适配器中相应的pin脚作为导电件与电源pin脚130的第一侧壁134电连接。可以理解的是，当电源接口100与电源适配器电连接时，电源适配器中相应的pin脚与电源pin脚130的第一侧壁134紧密贴合，从而可以实现电源接口100与电源适配器之间的稳定的电连接。
根据本发明的另一些实施例，凹陷部133还可以为两个，两个凹陷部133分别位于拓宽段132的第一侧壁134和第二侧壁135上，第一侧壁134适于与导电件电连接，第二侧壁135与第一侧壁134相对，两个凹陷部133在拓宽段132的宽度方向上间隔分布。例如，如图4-图8所示，拓宽段132的宽度方向可以为图4-图8中所示的左右方向，第一侧壁134朝向电源接口100的外侧(如图4所示的外侧方向)，第二侧壁135朝向电源接口100的内侧(如图4所示的内侧方向)，两个凹陷部133在左右方向上间隔分布，其中一个凹陷部133位于第一侧壁134上，另外一个凹陷部133位于第二侧壁135上。
如图7、图8所示，根据本发明的一个实施例，导电部130a的与绝缘部130b相连的壁面为第一壁面，绝缘部130b的与导电部130a相连的壁面为第二壁面，第一壁面与第二壁面中的至少一个上设有粗糙部140。由此可以增加导电部130a与绝缘部130b的接触面积， 从而可以增强导电部130a与绝缘部130b的连接牢固性。在本发明的一些示例中，如图7所示，粗糙部140可以形成为凸起部；在本发明的另一些实施例中，如图8所示，粗糙部140可以形成为凹槽；在本发明的有一些实施例中，粗糙部140还可以形成为粗糙面。
根据本发明的一些实施例，导电部130a上与第一壁面相邻的壁面为第三壁面，第一壁面与第三壁面之间设有倒角。需要说明的是，倒角的设置不但可以增大导电部130a与绝缘部130b之间接触面积，提升导电部130a与绝缘部130b的连接强度和连接可靠性，还可以使电源pin脚130的外表面圆滑过渡。另外，当需要利用冲压工艺加工电源pin脚130时，倒角部位还可以用于容纳冲压过程中产生的余料，从而可以提升电源pin脚130的外表面的光滑程度。
下面参照图1-图10详细描述根据本发明实施例的电源接口100。值得理解的是，下述描述仅是示例性说明，而不是对本发明的具体限制。
为方便描述，以电源接口100为Type-C为例。Type-C接口全称为USB Type-C接口，它是一种接口形式，是USB标准化组织为了解决USB接口长期以来物理接口规范不统一，电能只能单向传输等弊端而制定的全新数据、视频、音频、电能传输接口规范。
Type-C的特点在于标准的设备都可以通过接口规范中的CC引脚来向连接的另一方宣称自己占用VBUS的意愿(即传统USB的正端连接线)，较强意愿的一方最终向VBUS输出电压和电流，另一方则接受VBUS总线的供电，或者仍然拒绝接受供电，但不影响传输功能。为了能够更方便的使用这个总线定义。Type-C接口芯片(例如LDR6013)，一般把设备分为四种角色：DFP、Strong DRP、DRP、UFP。这四种角色占用VBUS总线的意愿依次递减。
其中，DFP相当于适配器，会持续想要向VBUS输出电压，Strong DRP相当于移动电源，只有当遇上适配器时，才放弃输出VBUS。DRP相当于手机，正常情况下，都期待对方给自己供电，但是遇上比自己还弱的设备时，则也勉为其难的向对方输出，UFP是不对外输出电能的，一般为弱电池设备，或者无电池设备，例如蓝牙耳机。USB Type-C支持正反插，由于正反两面一共具有四组电源和地，在功率支持上又可大幅度的提升。
本实施例中的电源接口100可以为USB Type-C接口，其可以适用于具有快速充电功能的电源适配器，也适用于普通电源适配器。这里，需要说明的是，快速充电可以指充电电流大于2.5A的充电状态；普通充电可以指充电电流小于等于2.5A的充电状态。也就是说，当利用具有快速充电功能的电源适配器给电源接口100充电时，充电电流大于等于2.5A；当利用普通电源适配器给电源接口100充电时，充电电流小于2.5A。
为了使电源接口100、与电源接口100相适配的电源适配器标准化，使电源接口100的尺寸满足标准接口的设计要求。例如，pin脚个数为24的电源接口100，其设计要求的宽度(电源接口100的左右方向上的宽度，如图1所示的左右方向)为a，为了使本实施 例中的电源接口100满足设计标准，本实施例中的电源接口100的宽度(电源接口100的左右方向上的宽度，如图1所示的左右方向)也为a。为使电源pin脚130能够在有限的空间内承载较大的充电电流，可以将24个pin脚中的部分pin脚省去，同时增大电源pin脚130的横截面积用于承载较大的充电电流，电源pin脚130增大的部分可以排布在被省略的pin脚的位置处，一方面实现了对电源接口100的部件的优化布局，另一方面增大了电源pin脚130所能承载电流的能力。
具体地，如图1-图3所示，电源接口100包括：主体部110、六个数据pin脚120和八个电源pin脚130。其中，六个数据pin脚120分别为A5、A6、A7、B5、B6、B7，八个电源pin脚130分别为A1、A4、A9、A12、B1、B4、B9、B12，八个电源pin脚130中包括四个VBUS和四个GND。相对的两个GND之间夹设有中间贴片150，需要说明的是，电源接口100可以设在移动终端上，移动终端(例如手机、平板电脑、笔记本电脑等)的内部可以设有电池，外部电源可以通过电源适配器与电源接口100连接，进而对电池进行充电。
主体部110适于与电路板连接，数据pin脚120为间隔开的多个且与主体部110连接。电源pin脚130可以为间隔开的多个且与主体部110连接。电源pin脚130和数据pin脚120间隔排布。多个电源pin脚130中的至少一个包括拓宽段132，拓宽段132位于电源pin脚130的中部。拓宽段132包括沿左右方向排布的导电部130a和绝缘部130b。导电部130a和绝缘部130b相连且在导电部130a和绝缘部130b连接的端面处设有台阶面，台阶面上形成有粗糙部140。导电部130a的横截面积大于数据pin脚120的横截面积以增加电源pin脚130的电流载荷量。拓宽段132可以占用被省略的pin脚的位置，一方面可以增加电源pin脚130所能够承载的充电电流，另一方面，可以提高电源接口100的空间利用率。
如图6、图10所示，电源pin脚130的厚度为D，拓宽段132的横截面积为S，经过实验验证，当D＝0.25mm，S＝0.13125mm2时，电源pin脚130的电流载荷量至少为12A，从而可以提升充电效率。如图6、图10所示，电源pin脚130具有适于与电源适配器电连接的接触面，在所述电源pin脚130的宽度方向(如图6、图10所示的左右方向)上，所述接触面的宽度为W，经过实验验证，当W＝0.25mm时，可以大幅提升电源pin脚130的电流载荷量，电源pin脚130的电流载荷量可以为10A、12A、14A或以上，从而可以提升充电效率。
如图4-图8所示，电源pin脚130的部分外表面、包裹数据pin脚120外表面包裹有包胶部139，其中包胶部139可以为由绝缘导热材料制成。
如图6所示，凹陷部133可以为两个，两个凹陷部133在左右方向(如图4-图8中所示的左右方向)上间隔分布。如图4、图5所示，第二侧壁135与第一侧壁134相对，第 一侧壁134适于与导电件电连接且朝向电源接口100的外侧(如图4所示的外侧方向)，第二侧壁135与第一侧壁134相对且朝向电源接口100的内侧(如图4所示的内侧方向)，其中一个凹陷部133位于第一侧壁134上，另外一个凹陷部133位于第二侧壁135上。
导电部130a上与第一壁面相邻的壁面为第三壁面，第一壁面与第三壁面之间设有倒角。需要说明的是，倒角的设置不但可以增大导电部130a与绝缘部130b之间接触面积，提升导电部130a与绝缘部130b的连接强度和连接可靠性，还可以使电源pin脚130的外表面圆滑过渡。另外，当需要利用冲压工艺加工电源pin脚130时，倒角部位还可以用于容纳冲压过程中产生的余料，从而可以提升电源pin脚130的外表面的光滑程度。
由此，通过在电源pin脚130上设置拓宽段132，可以增大电源pin脚130的电流载荷量，从而可以提高电流的传输速度，使电源接口100具有快速充电的功能，进而可以提升电池的充电效率。
根据本发明实施例的移动终端，包括如上所述的电源接口100。移动终端可以通过电源接口100实现电信号、数据信号的传递。例如，移动终端可以通过电源接口100与电源适配器电连接以实现充电或数据传输功能。
根据本发明实施例的移动终端，通过在电源pin脚130上设置拓宽段132，可以增大电源pin脚130的电流载荷量，从而可以提高电流的传输速度，使电源接口100具有快速充电的功能，进而可以提升电池的充电效率。

根据本发明实施例的电源适配器，通过在电源pin脚130上设置拓宽段132，可以增大电源pin脚130的电流载荷量，从而可以提高电流的传输速度，使电源接口100具有快速充电的功能，提升对电池的充电效率。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
