其中，连接管1连接于固定板20，插接件3连接于浮动板30。连接管1与固定板20连接并处于固定状态，插接件3与浮动板30连接，且浮动板30与插接件3能够随之汽车振动等各种影响而随之移动，从而实现电连接器在水连接时更加可靠，有效避免发生外漏现象。
弹性接管2的两端分别密封连接于连接管1和插接件3并用于冷源通过。插接组件10在密封状态时，连接管1用于连接冷却系统，冷却系统提供的冷源将依次通过连接管1、弹性接管2和插接件3，之后冷源流向至电池包内来实现对电池包的冷却。其中，在电连接器中的插接装置的数量可以为多个，通过多个插接装置实现循环冷却以及冷源的回收利用，节能环保。
弹性部22沿弹性接管2的径向方向向外隆起，且弹性部22的内径大于第一连接部21和第二连接部23的内径。通过弹性部22的内径大于第一连接部21和第二连接部23的内径，使得弹性部2更有利于产生形变，同时，利于冷源通过弹性接管2并流向至电池包内，保证了插接组件10在水连接时的稳定可靠性。
其中，弹性接管2的具体形状不作限定。在本实施方式中，弹性接管2的形状呈灯笼型，使得弹性接管2能够设置在固定板20与浮动板30之间的小空间内，解决实际安装空间问题。
第一连接部21、弹性部22和第二连接部23之间一体成型。有效加强了弹性接管2的结构强度，保证了插接组件10在水连接时的可靠性。同时，弹性接管2结构简单，便于制作。
弹性接管2由柔性材质制成。通过弹性接管2使得连接管1与插接件3之间实现浮动连接。优选地，弹性接管2的材料为橡胶，使得弹性接管2整体密封性能好，防水密封级别能够达到IP67以上，且降低了成本。
本实施例还公开了一种电动汽车，该电动汽车包括电池包、冷却系统以及如上所述的电连接器，电池包与插接件3连通，冷却系统与连接管1连通并用于提供冷源通过弹性接管2和插接件3，以实现进入电池包。冷却系统提供的冷源将会依次通过连接管1、弹性接管2和插接件3并进入至电池包内，通过冷源能够将降低电池包内的温度，提高电池充分能力，从而直接提高电动汽车的使用环境受限、车辆动力性能、电池寿命等性能指标。

实施例2
如图4和图5所示，本实施例的电连接器结构与实施例1的相同部分不再复述，仅对不同之处作说明。在本实施方式中，弹性接管的形状不是呈灯笼型，弹性接管的形状呈风琴状，也就是弹性部22的外表面呈凹凸不平的波浪形，使得弹性部22能够产生形变，连接管与插接件之间实现浮动连接，从而实现电连接器在水连接时更加可靠，有效避免发生外漏现象。
第一连接部21的外周面上具有向内凹陷的第一安装槽211，第一安装槽211通过紧箍套设于连接管。第一安装槽211具有限位作用，紧箍将套设在第一安装槽211内而不会产生脱离现象，使得第一连接部21与连接管之间实现密封连接，密封连接非常方便，且密封性能好。
第二连接部23的外周面上具有向内凹陷的第二安装槽231，第二安装槽231通过紧箍套设于插接件。第二安装槽231具有限位作用，紧箍将套设在第二安装槽231内而不会产生脱离现象，使得第二连接部23与插接件之间实现密封连接，密封连接非常方便，且密封性能好。
在本实施例中，弹性接管的两端分别通过紧箍来分别实现与连接管和插接件相连接，实现电连接器的防水密封级别能够达到IP67以上。当然，插接组件也可以采用快插结构来实现连接，即弹性接管的两端分别通过采用快插结构来分别实现与连接管和插接件相连接。连接管和插接件上也可以都安装有自锁结构，连接管和插接件均通过自锁结构来实现与弹性接管的安装连接，还是能够保证电连接器的防水密封级别达到IP67以上。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改。因此，本发明的保护范围由所附权利要求书限定。
