具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“顶”、“底”、“内”、“外”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。

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。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10所示，根据本发明实施例的电源接口100，包括：插接壳体110和插接主体120。
具体而言，插接壳体110内壁上设有止挡凹槽113，插接主体120设在插接壳体110内，插接主体120上具有第一包胶部130和多个间隔开的pin脚121，第一包胶部130包裹pin脚121的部分外周且与插接壳体110连接。需要说明的是，pin脚121上未被第一包胶部130包裹的表面被构造成插接主体120的外表面，pin脚121上未被第一包胶部130包裹的表面适于与相应的电源适配器内pin脚121电连接。
可以理解的是，利用第一包胶部130将多个pin脚121包裹在一起，插接主体120在反复插接的过程中，可以增强插接主体120的结构强度，延缓插接主体120的疲劳损坏。第一包胶部130的靠近pin脚121的后端(如图1所示的后侧方向)具有卡接凸缘131，卡接凸缘131卡接在止挡凹槽113内。由此可以使插接主体120稳定地安装在插接壳体110内。
第一包胶部为聚酰胺树脂包胶部。聚酰胺树脂具有良好的散热效果，从而可以满足插接主体120散热需求。需要说明的是，电源接口100在充电过程中，尤其是在快速充电的过程中，会产生大量的热量，热量聚集对电流传输的影响更加明显。
而根据本发明实施例的电源接口100，通过采用具有导电系数较高、散热效果好的聚酰胺树脂制成第一包胶部，可以有效地将充电时电流产生的热量传导出，从而便于实现使电源接口具有快速充电的功能。
根据本发明的一个实施例，如图6-图8所示，止挡凹槽113沿插接主体120的周向方向延伸。由此，止挡凹槽113可以与卡接凸缘131牢靠配合，从而可以将插接主体120稳定地装配在插接壳体110内，进而可以进一步增强插接主体120与插接壳体110之间的连接可靠性。
进一步地，如图1、图3所示，卡接凸缘131的自由端端面上设有卡接台阶132，止挡凹槽113内设有与卡接台阶132相适配的卡接适配部114。由此，可以增大卡接凸缘131与止挡凹槽113的接触面积，提高插接主体120与插接壳体110的配合稳定性。更进一步地，在如图1、图3所示的示例中，卡接凸缘131上设有多个卡接凹槽133，多个卡接凹槽133沿插接主体120的周向方向间隔分布，止挡凹槽113内具有与卡接凹槽133相适配的卡接凸起，由此可以进一步提高插接主体120与插接壳体110的配合稳定性。
根据本发明的另一个实施例，如图6、图7所示，止挡凹槽113的内壁上设有止挡凸起部115，止挡凸起部115嵌设在第一包胶部130内。由此，通过设置止挡凸起部115，使止 挡凸起部115嵌入在第一包胶部130内，从而可以增大止挡凹槽113和第一包胶部130之间的摩擦力，进而可以提升插接主体120与插接壳体110的装配稳定性。
根据本发明的一个实施例，第一包胶部130与插接壳体110内周壁之间设有胶粘层。一方面，可以使插接主体120与插接壳体110牢靠、稳定地装配在一起，另一方面，利用胶粘层将插接主体120与插接壳体110连接在一起，还可以提高电源接口100的拔插强度，延缓电源接口100因反复拔插操作而产生的疲劳损坏。
如图1-图4所示，根据本发明的一个实施例，插接主体120还包括：第二包胶部150。其中，第二包胶部150嵌设在第一包胶部130上，第二包胶部150的部分外周壁被构造成插接主体的前端面120a。需要说明的是，通过在插接主体120上设置两个包胶部，可以使插接主体120具有不同的性能，例如，第一包胶部130和第二包胶部150可以采用不同的材质制造而成，通过使用不同的材料可以使插接主体120满足不同的强度需求，另外，也可以通过选用不同的材料可以使插接主体120满足不同的散热需求。当然，通过采用第一包胶部130和第二包胶部150还可以使插接主体120具有美观的外观特性。
根据本发明的一个实施例，如图3-图4所示，第一包胶部130上设有主体嵌入缺口134和延伸嵌入缺口135。相应地，第二包胶部150包括主体嵌入部151和延伸嵌入部152，主体嵌入部151与延伸嵌入部152连接，主体嵌入部151与主体嵌入缺口134相适配，延伸嵌入部152与延伸嵌入缺口135相适配，延伸嵌入部的前端面152a被构造成插接主体的前端面120a。由此，可以将第一包胶部130和第二包胶部150稳定地连接在一起。可以理解的是，第一包胶部130和第二包胶部150将pin脚121包裹连接以形成插接主体120，利用主体嵌入部151与主体嵌入缺口134、延伸嵌入部152与延伸嵌入缺口135可以使pin脚121、第一包胶部130和第二包胶部150牢靠地装配在一起，从而可以提升插接主体120的结构强度和装配稳定性。
进一步地，如图8所示，第一包胶部130和第二包胶部150中的一个上设有嵌入凸起153，另一上设有与嵌入凸起153相适配的嵌入凹槽136。由此，可以进一步地增强第一包胶部130和第二包胶部150连接稳定性和可靠性。例如，在如图8所示的示例中，第一包胶部130上设有嵌入凹槽136，第二包胶部150上设有与嵌入凹槽136相适配的嵌入凸起153。
根据本发明的一个实施例，如图3所示，嵌入凸起153可以设在延伸嵌入部152上。进一步地，如图8所示，嵌入凸起153可以为间隔开的多个，相应的，嵌入凹槽136也为多个且与多个嵌入凸起153一一对应。由此，可以进一步地增强第一包胶部130和第二包胶部150连接稳定性和可靠性。
根据本发明的一个实施例，pin脚121包括电源pin脚121a和数据pin脚121b，电源 pin脚121a具有拓宽段1211，拓宽段1211的横截面积大于数据pin脚121b的横截面积以增加电源pin脚121a的电流载荷量。通过在电源pin脚121a上设置拓宽段1211，可以增大电源pin脚121a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。
根据本发明的一个实施例，拓宽段1211的靠近电源pin脚121a前端的位置处设有凹陷部1212。需要说明的是，当电源接口100进行快速充电时，具有拓宽段1211的电源pin脚121a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1211上的凹陷部1212可以避免电源pin脚121a与电源适配器上的对应pin脚121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2.5A的充电状态或者额定输出功率小于15W的充电状态。
根据本发明的一个实施例，如图9、图10所示，拓宽段1211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121a的电流载荷量至少为10A,由此可以通过提升电源pin脚121a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，如图9、图10所示，电源pin脚121a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pin脚121a的电流载荷量至少为10A,由此可以通过提升电源pin脚121a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121a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9、图10所示，电源pin脚121a具有适于与导电件电连接的接触面，在所述电源pin脚121a的宽度方向(如图9、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121a的电流载荷量至少为10A,由此可以通过提升电源pin脚121a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121a的电流载荷量，电源pin脚121a的电流载荷量为12A或以上，从而可以提升充电效率。
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；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。
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，需要使电源接口100的尺寸满足标准接口的设计要求。例如，pin脚121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121a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121中的部分pin脚121省去，同时增大电源pin脚121a的横截面积用于承载较大的充电电流，电源pin脚121a增大的部分可以排布在被省略的pin脚121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8所示，电源接口100包括：插接壳体110和插接主体120。其中，插接主体120包括：第一包胶部130、第二包胶部150和14个pin脚121。第一包胶部130 和第二包胶部150可以采用散热效果好的材料制成，例如，聚酰胺树脂(例如stanyl PA46)。聚酰胺树脂具有如下特性：
Thermal properties dry/cond    
Thermal conductivity in plane 2.1 W/(m K) ASTM E1461
Thermal conductivity through plane 0.9 W/(m K) ASTM E1461
需要说明的是，通过在插接主体120上设置两个包胶部，可以使插接主体120具有不同的性能，例如，第一包胶部130和第二包胶部150可以采用不同的材质制造而成，通过使用不同的材料可以使插接主体120满足不同的强度需求，另外，也可以通过选用不同的材料可以使插接主体120满足不同的散热需求。当然，通过采用第一包胶部130和第二包胶部150还可以使插接主体120具有美观的外观特性。
14个pin脚121包括六个数据pin脚121b和八个电源pin脚121a。六个数据pin脚121b分别为A5、A6、A7、B5、B6、B7，八个电源pin脚121a分别为A1、A4、A9、A12、B1、B4、B9、B12。八个电源pin脚121a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122。六个数据pin脚121b的后端和八个电源pin脚121a的后端分别与电路板160电连接。插接壳体110和中间贴片122分别与电路板160焊接。
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。
如图1-图4以及图8所示，中间贴片122包括头部1223和尾部1225。其中，头部1223具有镂空部1221，镂空部1221内部具有加强筋1222。头部1223上具有朝向远离插接主体120凸出的贴片凸起部1224。贴片凸起部1224可以增加中间贴片122与第一包胶部130或第二包胶部150的接触面积，从而可以提高中间贴片122与第一包胶部130或第二包胶部150之间的附着力，使中间贴片122连接得更加稳固。中间贴片122的尾部1225可以与电路板160焊接，同时尾部1225可以与插接壳体110间隔开，从而可以降低插接壳体110、中间贴片122对移动终端的天线的干扰。
通过在相对的两个电源pin脚121a之间设置中间贴片122，可以对电源pin脚121a起到支撑的作用，防止当电源适配器插入电源接口100时，相对的两个电源pin脚121a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，从而可以提高电源适配器与电源接口100之间连接的可靠性。同时，中间贴片122的头部1223设置镂空部1221，并在镂空部1221内设置加强筋1222，不但可以节约中间贴片122的材料，还可以提高中间贴片122的结构强度。
第二包胶部150嵌设在第一包胶部130上，第二包胶部150的部分外周壁被构造成插 接主体的前端面120a，第一包胶部130和第二包胶部150共同将pin脚121的部分外表面包裹在一起以构造成插接主体120。插接主体120设在插接壳体110内并与插接壳体110连接。需要说明的是，pin脚121上未被第一包胶部130包裹的表面被构造成插接主体120的外表面，pin脚121上未被第一包胶部130、第二包胶部150包裹的表面适于与相应的电源适配器内pin脚121电连接。第一包胶部130的靠近pin脚121的后端(如图1所示的后侧方向)具有卡接凸缘131。
如图6-图7所示，插接壳体110内壁上设有第一挡板111，第一挡板111可以通过注塑的形式与插接壳体110一体成型。插接壳体110内壁上还设有第二挡板112，第二挡板112与第一挡板111间隔开，第二挡板112焊接在插接壳体110的内部。第一挡板111与第二挡板112限定出止挡凹槽113，止挡凹槽113沿插接主体120的周向方向延伸，卡接凸缘131卡接在止挡凹槽113内。由此可以使插接主体120稳定地安装在插接壳体110内。如图1、图3所示，卡接凸缘131的自由端端面上设有卡接台阶132和多个卡接凹槽133，止挡凹槽113内设有与卡接台阶132相适配的卡接适配部114，多个卡接凹槽133沿插接主体120的周向方向间隔分布，止挡凹槽113内具有与卡接凹槽133相适配的卡接凸起，由此可以进一步提高插接主体120与插接壳体110的配合稳定性。
第一包胶部130、第二包胶部150与插接壳体110内周壁接触的位置处设有胶粘层。一方面，可以使插接主体120与插接壳体110牢靠、稳定地装配在一起，另一方面，利用胶粘层将接主体与插接壳体110连接在一起，还可以提高电源接口100的拔插强度，延缓电源接口100因反复拔插操作而产生的疲劳损坏。
如图3-图4所示，第一包胶部130上设有主体嵌入缺口134和延伸嵌入缺口135。相应地，第二包胶部150包括主体嵌入部151和延伸嵌入部152，主体嵌入部151与延伸嵌入部152连接，主体嵌入部151与主体嵌入缺口134相适配，延伸嵌入部152与延伸嵌入缺口135相适配，延伸嵌入部的前端面152a被构造成插接主体的前端面120a。由此，可以将第一包胶部130和第二包胶部150稳定地连接在一起。可以理解的是，第一包胶部130和第二包胶部150将pin脚121包裹连接以形成插接主体120，利用主体嵌入部151与主体嵌入缺口134、延伸嵌入部152与延伸嵌入缺口135可以使pin脚121、第一包胶部130和第二包胶部150牢靠地装配在一起，从而可以提升插接主体120的结构强度和装配稳定性。
如图3、图8所示，第一包胶部130上设有多个间隔开的嵌入凹槽136，延伸嵌入部152上设有与嵌入凹槽136相适配的嵌入凸起153。嵌入凸起153为间隔开的多个且与多个嵌入凹槽136一一对应。由此，可以进一步地增强第一包胶部130和第二包胶部150连接稳定性和可靠性。
如图1-图4所示，pin脚121包括电源pin脚121a和数据pin脚121b，电源pin脚121a的中部具有拓宽段1211，拓宽段1211的横截面积大于数据pin脚121b的横截面积以增加电源pin脚121a的电流载荷量。通过在电源pin脚121a上设置拓宽段1211，可以增大电源pin脚121a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。
拓宽段1211的靠近电源pin脚121a前端的位置处设有凹陷部1212。需要说明的是，当电源接口100进行快速充电时，具有拓宽段1211的电源pin脚121a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1211上的凹陷部1212可以避免电源pin脚121a与电源适配器上的对应pin脚121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。
如图9、图10所示，拓宽段1211的横截面积为S，电源pin脚121a的厚度为D，电源pin脚121a具有适于与导电件电连接的接触面，在所述电源pin脚121a的宽度方向(如图9、图10所示的左右方向)上，所述接触面的宽度为W，当S＝0.13125mm2、D＝0.25mm、W＝0.25mm时，可以大幅提升电源pin脚121a的电流载荷量，电源pin脚121a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。
由此，通过利用第一包胶部130和第二包胶部150将多个pin脚121包裹在一起，可以增强插接主体120的结构强度，从而在电源接口100的反复拔插使用过程中，可以延缓插接主体120的疲劳损坏。另外，通过在电源pin脚121a上设置拓宽段1211，可以增大电源pin脚121a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。
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。

并且，通过采用具有导电系数较高、散热效果好的聚酰胺树脂制成第一包胶部，可以有效地将充电时电流产生的热量传导出，从而便于实现使电源接口具有快速充电的功能
