目前，随着社会的经济发展及人类环保节能意识的逐步提高，新能源汽车也越来越被认可。随着新能源汽车的发展，人们对新能源汽车的续航里程的要求也在提 高。为了提高新能源汽车的续航里程，技术人员提出了快充和快换两种解决方案。快充方案是通过提高充电倍率而减少充电时间，而快换方案是通过将低电量的电池更换为一个满电的电池而实现电能补充。为实现车辆的快换方案，电池必须满足快换要求，这就需要在传统电池的基础上将普通连接器更换为快换连接器，以实现电池的快换。
发明人发现，新能源汽车的电池普遍安装于车辆的底盘上，电池的连接器插头与车辆的连接器插座插接配合实现电池与车辆的用电系统之间的电连接，然而，电池的连接器插头设置于电池的顶部，连接器插头是沿竖直方向朝上插接于车辆的连接器插座上，以导致在下雨天气或车辆涉水后进行换电的过程中，连接器插头极容易出现进水的现象。然而，现有技术中的连接器插头设置有密封结构或防护外壳，以将连接器插头的两个公端连接端子设置于该密封结构或防护外壳内，形成密封界面，从而起到一定的防护和密封作用，但是，由于密封结构或防护外壳也形成了一个密闭空间，使得连接器插头在出现进水现象后，密封结构或防护外壳内极容易出现积水的现象，且积水不易排出，从而造成两个金属连接端子之间的电气间隙和爬电距离减小，容易出现电连接异常和绝缘异常的风险，进而造成连接器插头出现短路的现象，以使车辆在使用过程中存在较大的安全隐患。
基于以上考虑，为了解决车辆在使用的过程中存在较大的安全隐患的问题，发明人经过深入研究，设计了一种连接器插头，通过取消连接器插头上的防护外壳，并在连接器插头的底座设置多个凸台，将每个公端连接端子分别安装于对应凸台上，且在每个凸台上均设置密封件，以使密封件在连接器插头的公端连接端子插接于连接器插座的母端连接端子内时能够密封凸台与母端连接端子之间的间隙，从而起到密封作用。
在采用这种结构的连接器插头实现电池的快换过程中，由于将每个公端连接端子安装在底座对应的凸台上，且每个凸台均设置有密封件，以密封凸台与母端连接端子之间的间隙，一方面无需再设置防护外壳，有利于在连接器插头在出现进水现象时降低积水风险，且在连接器插头进水后能够便于积水排出，从而能够降低连接器插头出现电连接异常和绝缘异常的风险，以减少车辆在使用过程中存在的安全隐患，另一方面通过对每个公端连接端子进行单独密封，使得密封界面内只包含单独的公端连接端子，从而有利于降低多个公端连接端子之间出现连接异常的风险。
此外，通过将每个公端连接端子设置于一个凸台上，也就是说，每个公端连接端子的底部均设置有凸台，从而能够有效增加多个公端连接端子之间的爬电距离，有利于降低连接器插头的使用风险。
本申请实施例公开的连接器插头可以但不限用于车辆、船舶或飞行器等用电装置中。可以使用具备本申请公开的连接器插头、电池等组成该用电装置的电源系统，这样，有利于降低用电装置出现电连接异常和绝缘异常的风险，以减少用电装置在使用过程中存在的安全隐患。

根据本申请的一些实施例，请参照图2，并请进一步参照图4-图6，图4为本申请一些实施例提供的连接器插头30与连接器插座500的连接示意图，图5为本申请一些实施例提供的连接器插头30的结构爆炸图，图6为本申请一些实施例提供的连接器插座500的剖视图。本申请提供了一种连接器插头30，连接器插头30包括底座31和多个公端连接端子32。底座31包括底座本体311和多个凸台312，多个凸台312间隔设置于底座本体311。公端连接端子32与凸台312对应设置，公端连接端子32从凸台312背离底座本体311的一侧伸出。
公端连接端子32从凸台312背离底座本体311的一侧伸出是指公端连接端子32安装于凸台312内，且公端连接端子32的一端延伸出凸台312背离底座本体311的一侧，以使公端连接端子32的部分凸出于凸台312。
其中，底座本体311用于安装于电池100的箱体10上，公端连接端子32用于与电池单体20电连接。连接器插座500具有母端连接端子510，母端连接端子510开设有供公端连接端子32插入的插接孔511，以实现公端连接端子32与母端连接端子510之间的电连接。连接器插座500的具体结构可参见相关技术，在此不再赘述。
可选地，底座本体311在其厚度方向上的一侧具有面向连接器插座500的对接面3111，多个凸台312间隔设置于对接面3111上，采用这种结构在连接器插头30出现进水现象时便于积水从对接面3111上排出，以减少连接器插头30的积水现象。
凸台312可以为两个、三个、四个、五个等。示例性的，在图5中，凸台312和公端连接端子32均为两个，两个凸台312沿底座本体311的长度方向间隔排布于对接面3111上，当然，两个凸台312也可以沿底座本体311的宽度方向间隔排布于对接面3111上。
示例性的，底座31为绝缘材质。底座31的材质可以为塑料、橡胶或硅胶等。
可选地，请参照图5和图6，并请进一步参照图7，图7为本申请一些实施例提供的连接器插头30插接于连接器插座500的剖视图。连接器插座500上具有定位孔520，底座31还包括定位销313，定位销313设置于底座本体311的对接面3111上，定位销313用于在公端连接端子32插接于母端连接端子510的插接孔511内时插设于定位孔520内，以将底座31定位于连接器插座500上，从而有利于提高连接器插头30插接于连接器插座500的插接精度和准确度。
示例性的，定位销313和定位孔520均为两个。
底座31设置有底座本体311和多个凸台312，多个凸台312间隔设置于底座本体311上，且在每个凸台312上对应设置一个公端连接端子32，以使每个公端连接端子32伸出凸台312的部分均高于底座本体311，采用这种结构的连接器插头30在下雨天气或车辆1000涉水后进行换电的过程中，一方面在连接器插头30进水后能够便于底座本体311上的积水排出，降低连接器插头30出现积水的风险，从而能够降低连接器插头30出现电连接异常和绝缘异常的风险，另一方面由于公端连接端子32伸出凸台312的部分均高于底座本体311，以使凸台312能够对公端连接端子32与底座本体311上形成的积水面进行隔离，使得底座本体311上形成的积水面不会造成多个公端连 接端子32之间形成电连接，从而能够减少连接器插头30出现短路的现象，进而有利于减少具有这种连接器插头30的用电装置在使用过程中的安全隐患。此外，通过将每个公端连接端子32对应设置于一个凸台312上，也就是说，每个公端连接端子32的底部均设置有凸台312，从而有利于增加多个公端连接端子32之间的爬电距离和爬电间隙，进而能够进一步提高连接器插头30的使用安全。
根据本申请的一些实施例，可选地，请参照图8，图8为本申请一些实施例提供的连接器插头30的剖视图。凸台312环绕于公端连接端子32的外侧。
凸台312环绕于公端连接端子32的外侧是指公端连接端子32设置于凸台312的部分被凸台312包覆，凸台312沿公端连接端子32的周向覆盖于公端连接端子32的外侧。
其中，凸台312上开设有安装孔3121，安装孔3121贯穿凸台312背离底座本体311的一侧，安装孔3121沿底座本体311的厚度方向延伸至底座本体311内并贯穿底座本体311背离凸台312的一侧。公端连接端子32的部分安装于安装孔3121内，一方面实现凸台312环绕于公端连接端子32的外侧，另一方面便于公端连接端子32与电池单体20进行电连接。
通过将凸台312设置为环绕于公端连接端子32的外侧，也就是说，每个公端连接端子32的底部均被对应的凸台312包覆，以减少公端连接端子32在凸台312的周向上出现裸露的现象，从而有利于提高多个公端连接端子32之间的爬电距离和爬电间隙，以降低连接器插头30的使用风险。
根据本申请的一些实施例，可选地，请继续参考图8，多个凸台312凸出于底座本体311的高度相等。
通过将多个凸台312设置为凸出于底座本体311的高度均相等，一方面便于对底座31进行加工和制造，有利于降低连接器插头30的制造成本，另一方面在公端连接端子32插接于连接器插座500的母端连接端子510时便于凸台312与母端连接端子510进行对接，有利于对凸台312和母端连接端子510之间的间隙进行密封。
根据本申请的一些实施例，可选地，请继续参考图8，凸台312凸出于底座本体311的高度为3-5mm。
通过将凸台312的高度设置在3-5mm之间，一方面能够提高凸台312对公端连接端子32与底座本体311上形成的积水面之间的隔离效果，另一方面能够减少因凸台312的高度过高而造成不必要的浪费的现象，从而有利于降低连接器插头30的材料成本，且能够减少因凸台312的高度过高而出现连接器插头30与连接器插座500的插接效果较差的问题。
根据本申请的一些实施例，可选地，请继续参考图8，凸台312与底座本体311一体成型。
凸台312与底座本体311一体成型是指凸台312与底座本体311通过注塑工艺加工的一体成型结构。
通过将凸台312和底座本体311设置为一体成型结构，以降低凸台312与底座本体311之间因存在间隙而出现积水渗入且与公端连接端子32出现导通的现象，从而有利于降低多个公端连接端子32之间出现爬电距离和爬电间隙减小的风险。
根据本申请的一些实施例，可选地，请参考图7和图8，连接器插头30还包括多个密封件33。密封件33与凸台312对应设置，密封件33用于密封凸台312与连接器插座500的母端连接端子510。
其中，在公端连接端子32插接于母端连接端子510的插接孔511内时，密封件33位于凸台312与母端连接端子510之间，以密封凸台312与母端连接端子510之间的缝隙。
示例性的，密封件33为两个，每个凸台312对应设置一个密封件33。
示例性的，密封件33的材质可以为塑料、橡胶或硅胶等。
通过密封件33能够在公端连接端子32插接于母端连接端子510时密封凸台312与母端连接端子510之间的缝隙，从而在用电装置运行的过程中有利于降低积水出现从凸台312与母端连接端子510之间的缝隙渗入的现象，以降低具有这种连接器插头30的用电装置的安全隐患。
根据本申请的一些实施例，可选地，请参照图8，并请进一步参照图9，图9为图8所示的连接器插头30的A处的局部放大图。密封件33具有通孔331，通孔331包括第一孔段3311和第二孔段3312，第一孔段3311的直径大于第二孔段3312的直径，第一孔段3311用于容纳凸台312，第二孔段3312用于容纳公端连接端子32的部分。
密封件33上设置有通孔331，且通孔331包括第一孔段3311和直径小于第一孔段3311的第二孔段3312，凸台312容纳于第一孔段3311内，公端连接端子32的部分容纳于第二孔段3312内，也就是说，密封件33的一部分套设于凸台312的外侧，另一部分套设于公端连接端子32的外侧并抵接于凸台312背离底座本体311的一侧上。当公端连接端子32插设于母端连接端子510的插接孔511内时，密封件33套设于公端连接端子32的外侧的部分位于凸台312与母端连接端子510之间，以实现凸台312与母端连接端子510的轴向密封。
采用这种结构的密封件33一方面通过凸台312能够对密封件33起到一定的限位和定位作用，从而有利于提高密封件33套设于公端连接端子32上的结构稳定性，另一方面增加了凸台312的密封界面，凸台312的外周面和背离底座本体311的一侧均覆盖于密封件33内，从而有利于提高凸台312与连接器插座500的母端连接端子510之间的密封效果。
根据本申请的一些实施例，可选地，请参照图10，图10为本申请又一些实施例提供的连接器插头30插接于连接器插座500的剖视图。密封件33套设于公端连接端子32的外侧，且抵接于凸台312背离底座本体311的一侧。
通过将密封件33套设于公端连接端子32的外侧，且将密封件33抵接在凸台312背离底座本体311的一侧，从而在公端连接端子32插接于连接器插座500的母端连接端子510内时，使得密封件33能够沿公端连接端子32的周向环绕于公端连接端子32的外侧且位于凸台312与母端连接端子510之间，以实现凸台312与母端连接端子510的轴向密封，结构简单，且便于实现。
根据本申请的一些实施例，可选地，请参照图11和图12，图11为本申请再一些实施例提供的连接器插头30插接于连接器插座500的剖视图，图12为图11的连接器插头30的B处的局部放大图。凸台312的外周面上开设有绕凸台312的周向延伸的 环形槽3122。环形槽3122用于容纳密封件33，密封件33的外周面凸出于凸台312的外周面。
密封件33的外周面凸出于凸台312的外周面是指在密封件33套设于环形槽3122内后密封件33的部分位于环形槽3122内，另一部分凸出于凸台312的外周面，从而在公端连接端子32插设于母端连接端子510的插接孔511内时，凸台312也插设于插接孔511内，使得密封件33位于凸台312的外周面与插接孔511的孔壁之间，以实现凸台312与母端连接端子510的径向密封。
设置于凸台312上的密封件33可以为一个，也可以为多个。示例性的，在图12中，每个凸台312上设置有两个密封件33，凸台312的外周面上开设有沿底座本体311的厚度方向间隔布置的两个环形槽3122，每个环形槽3122用于容纳一个密封件33。
采用这种结构的密封件33能够实现凸台312与母端连接端子510之间的多重密封，从而有利于提高凸台312与连接器插座500的母端连接端子510之间的密封效果，且通过开设于凸台312上的环形槽3122能够对密封件33起到一定的限位和定位作用，便于密封件33的安装和使用。
根据本申请的一些实施例，可选地，请参照图13，图13为本申请另一些实施例提供的连接器插头30插接于连接器插座500的剖视图。凸台312与底座本体311分体设置且相互连接。凸台312被配置为密封底座本体311与连接器插座500的母端连接端子510。
凸台312与底座本体311分体设置是指凸台312与底座本体311为独立的两部分，非一体成型结构。
其中，凸台312起到密封底座本体311与母端连接端子510之间的缝隙的作用，凸台312密封连接于底座本体311上，以降低凸台312与底座本体311之间存在间隙的风险，也就是说，凸台312即为在公端连接端子32插接于母端连接端子510的插接孔511内时密封底座本体311与母端连接端子510的密封垫。可选地，凸台312可以通过粘接或热熔等方式连接于底座本体311上。
示例性的，凸台312的材质可以为塑料、橡胶或硅胶等。
通过将凸台312和底座本体311设置为分体式结构，且凸台312连接于底座本体311上，凸台312在公端连接端子32插接于母端连接端子510内时能够密封底座本体311与母端连接端子510之间的缝隙，一方面能够起到密封作用，降低积水通过凸台312与底座本体311之间的缝隙渗入而造成多个公端连接端子32之间的爬电距离和爬电间隙减小的风险，另一方面采用这种结构的底座31便于制造和加工，有利于降低底座31的制造难度。
根据本申请的一些实施例，参见图5至图9，本申请提供了一种连接器插头30，底座31包括底座本体311和两个凸台312，底座本体311在其厚度方向上具有对接面3111，两个凸台312沿底座本体311的长度方向间隔设置于对接面3111上，且两个凸台312凸出于底座本体311的高度相同，每个凸台312上对应设置一个公端连接端子32和密封件33，密封件33用于在公端连接端子32插接于母端连接端子510的插接孔511内时密封凸台312与母端连接端子510。公端连接端子32设置于凸台312内，且从凸台312背离底座本体311的一侧伸出。密封件33开设有通孔331，通孔 331包括第一孔段3311和第二孔段3312，第一孔段3311的直径大于第二孔段3312的直径，第一孔段3311用于容纳凸台312，第二孔段3312用于容纳公端连接端子32的部分。采用这种结构的连接器插头30在下雨天气或车辆1000涉水后进行换电的过程中，在连接器插头30进水后能够便于底座本体311上的积水排出，降低连接器插头30出现积水的风险，从而能够降低连接器插头30出现电连接异常和绝缘异常的风险，且通过凸台312能够对公端连接端子32与底座本体311上形成的积水面进行隔离，从而能够减少两个公端连接端子32之间出现短路的现象，进而有利于减少连接器插头30在使用过程中的安全隐患。
