下面参考图1-图11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11所示，根据本发明实施例的电源接口100，包括插接壳体1、插接主体2和中间贴片23。
具体而言，插接主体2设在插接壳体1内，插接主体2适于与电路板25连接且包括至少一对电源pin脚21，每对电源pin脚21中包括两个在上下方向(如图1所示的上下方向)上间隔开电源子pin脚211。中间贴片23夹设在两个电源子pin脚211之间，中间贴片23可以起到支撑电源子pin脚211的作用，防止当连接线插入电源接口100时，在上下方向上间隔开的两个电源子pin脚211朝向相互靠近的方向偏离而造成连接线与电源接口100接触不良，从而保证连接线与电源接口100之间连接的可靠性。中间贴片23具有靠近电源pin脚21的前端(如图1所示的前端)的头部和靠近电源pin脚21后端(如图1所示的后端)的尾部，尾部与插接壳体1间隔开且与插接主体2连接。尾部与插接壳体1间隔开可 以避免对天线信号产生干扰，提高信号传输的质量和速度。另外，尾部与插接壳体1均与插接主体2连接，可以将中间贴片23、插接壳体1和插接主体2三者连接在一起，提高中间贴片23、插接壳体1和插接主体2之间连接的可靠性。
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。
根据本发明实施例的电源接口100，通过将中间贴片23的尾部与插接壳体1间隔开且与插接主体2连接，可以避免对天线信号产生干扰，提高信号传输的质量和速度。另外，尾部与插接壳体1均与插接主体2连接，可以将中间贴片23、插接壳体1和插接主体2三者连接在一起，提高中间贴片23、插接壳体1和插接主体2之间连接的可靠性。
在本发明的一些实施例中，如图1和图5所示，插接主体2的电路板25上设有间隔开的第一焊盘251和第二焊盘252，插接壳体1与第一焊盘251焊接，尾部与第二焊盘252焊接。由此，可以将插接壳体1和中间贴片23与电路板25连接在一起，从而将插接主体2与电路板25牢固的固定在一起，防止插接主体2上的电源pin脚21与电路板25发生分离，从而保证电源接口100工作的可靠性。
在本发明的一些实施例中，如图2所示，至少一个电源子pin脚211包括拓宽段2111，拓宽段2111的横截面积大于插接主体2的数据pin脚22的横截面积以增加电源子pin脚211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。
可选地，如图11所示，拓宽段2111的横截面积为S，S≥0.09805mm2。经过实验验证，当S≥0.09805mm2时，电源子pin脚211的电流载荷量至少为10A,由此可以通过提升电源子pin脚211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，电源子pin脚211的电流载荷量为12A或以上，由此可以提升充电效率。
进一步地，如图11所示，电源子pin脚211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时，电源子pin脚211的电流载荷量至少为10A，由此可以通过提升电源子pin脚211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，可电源子pin脚211的电流载荷量为12A或以上，由此可以提升充电效率。
如图9-图11所示，电源子pin脚211具有适于与电源适配器电连接的接触面，在电源子pin脚211的宽度方向(如图11所示的左右方向)上，接触面的宽度为W，W满足：0.24mm≤W≤0.32mm。经过实验验证，当0.24mm≤W≤0.32mm时，电源子pin脚211的电流载荷量至少为10A,由此可以通过提升电源pin子脚211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，可以大幅提升电源子pin脚211的电流载荷量，电源子pin脚211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2111可以位于电源子pin脚211的中部。由此，可以优化多个电源子pin脚211和多个数据pin脚22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。
进一步地，如图2所示，拓宽段2111的、靠近所述电源子pin脚211前端的位置处设有凹陷部2112。需要说明的是，当电源接口100进行快速充电时，具有拓宽段2111的电源子pin脚211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2111上的凹陷部2112可以避免电源子pin脚211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充电接口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。
在本发明的一些实施例中，如图1和图5和图6所示，电源接口100还包括包胶部24，中间贴片23和插接主体2被包胶部24包裹。其中包胶部24可以为由绝缘导热材料制成。包胶部24可以起到固定中间贴片23以及插接主体2上的电源pin脚21和数据pin脚22的目的，从而保证电源适配器的连接线与电源接口100之间连接的可靠性。其中，包胶部24包括第一包胶部241和第二包胶部242，第一包胶部241和第二包胶部242相互配合，第二包胶部242上设有多个嵌入凹槽2421，第一包胶部241上设有多个嵌入凸起2411，嵌入凹槽2421与嵌入凸起2411一一对应且相互配合以增加第一包胶部241和第二包胶部242之间连接的可靠性。
如图3所示，头部上设有镂空部231，镂空部231内具有加强筋232。不但可以节省中间贴片23的材料，同时，在镂空部231设置加强筋232，可以提高中间贴片23的结构强度。
在本发明的一些实施例中，如图3所示，加强筋232沿左右方向延伸。由此，可以加强中间贴片23的结构强度。当然，本发明不限于此，加强筋232还可以沿前后方向延伸，或者加强筋232的延伸方向与左右方向成一定的角度，只要能够实现加强中间贴片23的结构强度即可。
在本发明的一些实施例中，如图3所示，头部具有朝向远离插接主体2凸出的加强凸起233。加强凸起233可以增加中间贴片23与包胶部24的接触面积，提高中间贴片23与 包胶部24之间的附着力，使中间贴片23和包胶部24之间连接更加稳固，从而可以通过包胶部24更好的将中间贴片23和插接主体2固定在一起。
可选地，如图3所示，加强凸起233位于头部的侧壁面和/或前端面上。例如，在图3所示的示例中，头部的前端面上设有加强凸起233，头部的左侧壁上也设有加强凸起233。由此，可以增加中间贴片23与包胶部24的接触面积，提高中间贴片23与包胶部24之间的附着力，使中间贴片23和包胶部24之间连接更加稳固，从而可以通过包胶部24更好的将中间贴片23和插接主体2固定在一起。
如图3所示，为增加中间贴片23的弹性，中间贴片23的中部具有避让凹槽234。由此，当中间贴片23向上或下偏离时，可以很快的恢复到原来的位置，便于下次电源适配器的电源线与电源接口100的连接。
在本发明的一些实施例中，如图3所示，尾部具有翻边235，一对电源pin脚21中的其中一个适于被翻边235包裹。一方面，翻边235可以增加中间贴片23与包胶部24的接触面积，提高中间贴片23与包胶部24之间的附着力，使中间贴片23和包胶部24之间连接更加稳固，从而可以通过包胶部24更好的将中间贴片23和插接主体2固定在一起。另一方面，翻边235还可以起到保护电源pin脚21的作用。
另外，如图3所示，尾部具有镂空部231。由此可以进一步的节约中间贴片23的材料。当然，为确保中间贴片23的结构强度，镂空部231内可以设置加强筋232。
在本发明的一些实施例中，如图4、图5、图7和图8所示，插接壳体1内设有第一挡板11，插接主体2上设有卡接凸缘2422，电源接口100还包括第二挡板3，第二挡板3位于插接壳体1内且与插接壳体1连接，第二挡板3与第一挡板11间隔开，卡接凸缘2422夹设在第一挡板11和第二挡板3之间。由此，通过第一挡板11和第二挡板3可以将插接主体2固定于插接壳体1内，防止插接主体2沿插接壳体1的上下方向移动，防止插接主体2由插接壳体1内脱离，从而当电源适配器的连接线插入电源接口100时，可以提高连接线与电源接口100之间连接的可靠性。
可选地，插接壳体1与第二挡板3均为金属件，第二挡板3与插接壳体1焊接。金属件的结构强度较大，可以提高电源接口100的结构强度，防止电源接口100在长时间使用之后或频繁的插拔之后出现变形等情况。另外，由于插接壳体1内部空间有限，第二挡板3与插接壳体1焊接连接，可以简化加工和装配的工艺，节约生产周期，降低生产成本。
优选地，第二挡板3为不锈钢件。由此，可以避免第二挡板3生锈，防止第二挡板3上的铁锈等影响插接主体2出现接触不良的现象，保证电源接口100工作的可靠性。
在本发明的一些实施例中，如图8所示，第二挡板3与插接壳体1之间具有缝隙31，缝隙31内设有胶粘层。一方面，粘胶层可以将第二挡板3与插接壳体1进一步地粘结在一起，提高第二挡板3与插接壳体1之间连接的可靠性，另一方面，粘胶层具有防水的作用，防止液体通过电源接口100的开口端进入电源接口100内部，损坏电源接口100内部的电路板25等，从而保证电源接口100工作的可靠性。
具体地，粘胶层为点胶层。点胶是一种工艺，是把电子胶水、油或者其他液体涂抹、灌封、点滴到产品上，让产品起到黏贴、灌封、绝缘、固定、表面光滑等作用。一方面，点胶层可以将第二挡板3与插接壳体1进一步地粘结在一起，提高第二挡板3与插接壳体1之间连接的可靠性，另一方面，点胶层具有防水的作用，防止液体通过电源接口100的开口端进入电源接口100内部，损坏电源接口100内部的电路板25等，从而保证电源接口100工作的可靠性。
在本发明的一些实施例中，如图4-图7所示，第二挡板3沿插接主体2的周向方向延伸。一方面，可以增强第二挡板3与壳体之间连接的可靠性；另一方面可以加强第二挡板3对插接主体2的固定效果。从而保证插接主体2牢固地固定在插接壳体1内，提高电源接口100与电源适配器的电源线连接的可靠性。
可选地，第二挡板3为多个。由此便于第二挡板3的加工。需要说明的是，多个第二挡板3可以沿插接壳体1的周向方向间隔分布，多个第二挡板3还可以组成一个环形挡板。多个第二挡板3分别与插接壳体1进行连接，从而实现对插接主体2的固定。
在本发明的一些实施例中，如图4-图7所示，第一挡板11沿插接主体2的周向方向延伸。由此，可以加强第一挡板11对插接主体2的固定效果。可选地，第一挡板11的朝向第二挡板3的壁面上设有止挡凸起部111，止挡凸起部111嵌入至卡接凸缘2422上。由此，第一挡板11和第二挡板3在固定插接主体2沿插接壳体1的上下方向移动的同时，还可以通过卡接凸缘2422和止挡凸起部111的配合，避免插接主体2在插接壳体1内发生晃动，从而保证电源接口100工作的可靠性。
下面参照图1-图11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。为了能够更方面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或者额定输出功率不小于15W；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。
具体地，如图1-图8所示，电源接口100包括插接壳体1、插接主体2、中间贴片23、包胶部24。插接主体2设在插接壳体1内，插接主体2适于与电路板25连接且包括四对电源pin脚21，每对电源pin脚21包括两个在上下方向上间隔开的电源子pin脚211。中间贴片23设在两个电源子pin脚211之间，可以防止在上下方向上间隔设置的两个电源子pin脚211朝向相互靠近的方向偏离而造成电源适配器的连接线与电源接口100接触不良。中间贴片23和插接主体2被包胶部24包裹。
其中，包胶部24可以为由绝缘导热材料制成。包胶部24可以起到固定中间贴片23以及插接主体2上的电源pin脚21和数据pin脚22的目的，从而保证电源适配器的连接线与电源接口100之间连接的可靠性。如图1、图5和图6所示，包胶部24包括第一包胶部241和第二包胶部242，第二包胶部242上设有多个嵌入凹槽2421，第一包胶部241上设有多个嵌入凸起2411，嵌入凹槽2421与嵌入凸起2411一一对应且相互配合以增加第一包胶部241和第二包胶部242之间连接的可靠性。
如图3所示，中间贴片23具有靠近电源pin脚21前端的头部和靠近电源pin脚21后端的尾部。头部上设有镂空部231，镂空部231内设置有加强筋232，加强筋232沿左右方 向延伸，不但可以节约中间贴片23的材料，还可以加强中间贴片23的强度。头部的前端面和左侧壁上具有朝向远离插接主体2凸出的加强凸起233。加强凸起233可以增加中间贴片23与包胶部24的接触面积，提高中间贴片23与包胶部24之间的附着力，使中间贴片23和包胶部24之间连接更加稳固，从而可以通过包胶部24更好的将中间贴片23和插接主体2固定在一起。
如图3所示，中间贴片23的中部具有避让凹槽234，当中间贴片23向上或下偏离时，可以很快的恢复到原来的位置。尾部具有翻边235，电源pin脚21中的一个适于被翻遍包裹。翻边235可以增加中间贴片23与包胶部24的接触面积，还可以起到保护电源pin脚21的作用。尾部具有加宽部236，加宽部236具有镂空部231，可以进一步的节约中间贴片23的材料。
另外，如图1、图5和图6所示，尾部与插接壳体1间隔开且与插接主体2连接以避免对天线信号产生干扰，提高信号传输的质量和速度，插接主体2的电路板25上设有间隔开的第一焊盘251和第二焊盘252，插接壳体1与第一焊盘251焊接，尾部与第二焊盘252连接以将插接壳体1和中间贴片23与电路板25连接在一起，从而将插接主体2与电路板25牢固的固定在一起，防止插接主体2上的电源pin脚21与电路板25发生分离，从而保证电源接口100工作的可靠性。
如图2所示，至少一个电源子pin脚211包括拓宽段2111，拓宽段2111的横截面积大于插接主体2的数据pin脚22的横截面积以增加电源子pin脚211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。拓宽段2111的、靠近电源子pin脚211前端的位置处设有凹陷部2112。当电源接口100进行快速充电时，具有拓宽段2111的电源子pin脚211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2111上的凹陷部2112可以避免电源子pin脚211与电源适配器上的对应pin脚接触。
其中，如图11所示，电源子pin脚211的厚度为D，拓宽段2111的横截面积为S，经过实验验证，当D＝0.25mm，S＝0.13125mm2时，电源子pin脚211的电流载荷量至少为12A，从而可以提升充电效率。进一步地，如图11所示，当W＝0.25mm时，电源子pin脚211的电流载荷量可以为14A或以上，从而可以提升充电效率。
另外，如图4-图8所示，插接壳体1内设有第一挡板11，第二包胶部242上设有卡接凸缘2422，电源接口100还包括第二挡板3，第二挡板3位于插接壳体1内且与插接壳体1连接，第二挡板3与第一挡板11间隔开，卡接凸缘2422夹设在第一挡板11和第二挡板3 之间。由此，通过第一挡板11和第二挡板3可以将第二包胶部242固定于插接壳体1内，从而将插接主体2固定于插接壳体1内，防止插接主体2沿插接壳体1的上下方向移动。
其中，插接壳体1与第二挡板3均为金属件且第二挡板3为不锈钢件，第二挡板3与插接壳体1通过点焊连接。金属件的结构强度较大，可以提高电源接口100的结构强度，由于插接壳体1内部空间有限，第二挡板3与插接壳体1焊接连接，可以简化加工和装配的工艺，节约生产周期，降低生产成本。第二挡板3与插接壳体1之间还具有缝隙31，缝隙31内设有点胶层。一方面，点胶层可以将第二挡板3与插接壳体1进一步地粘结在一起，提高第二挡板3与插接壳体1之间连接的可靠性，另一方面，点胶层具有防水的作用，防止液体通过电源接口100的开口端进入电源接口100内部，损坏电源接口100内部的电路板25等，从而保证电源接口100工作的可靠性。第二挡板3为两个，两个第二挡板3均沿插接壳体1的周向方向延伸，两个第二挡板3构成一个环形挡板。由此，可以增强第二挡板3与插接壳体1之间连接的可靠性，还可以简化第二挡板3的结构。
第一挡板11沿插接主体2的周向方向延伸以加强第一挡板11对插接主体2的固定效果。第一挡板11的朝向第二挡板3的壁面上设有止挡凸起部111，止挡凸起部111嵌入至相邻两卡接凸缘2422之间的卡接凹槽2423内以通过卡接凸缘2422和止挡凸起部111的配合，避免插接主体2在插接壳体1内发生晃动，从而保证电源接口100工作的可靠性。

根据本发明实施例的电源接口100的制造方法，可以将插接主体2固定于插接壳体1内，保证电源接口100工作的可靠性。
其中，步骤S10中的插接壳体1为注塑件，第一挡板11注塑形成在插接壳体1的内壁上。由此便于插接壳体1和第一挡板11的加工。步骤S30中，第二挡板3与插接壳体1通过点焊连接。点焊是一种高速、经济的连接方法。是把焊件在接头处接触面上的个别点焊接起来。
另外，第二挡板3与插接壳体1的内壁具有缝隙31。电源接口100的制造方法还包括 在缝隙31内设置胶粘层，由此可以将第二挡板3与壳体紧密的贴合在一起，并能防止液体进入电源接口100的内部。
