弹性接管142由柔性材质制成。通过弹性接管142使得连接管143与插接头141之间实现浮动连接。优选地，弹性接管142的材料为橡胶，降低了成本。
安装座12中朝向第一固定板11的一侧设有若干个凸起部121，若干个凸起部121与若干个接插组件14一一对应，弹性接管142和插接头141分别连接于凸起部121的两端并通过凸起部121相连通。凸起部121将沿靠近第一固定板11的方向向外延伸凸起，将弹性接管142和插接头141分别连接在凸起部121的两端上，增加了接插组件14与安装座12之间的连接面积，实现连接方便，且连接强度高。
插接头141密封连接于凸起部121的内壁面，弹性接管142密封套设于凸起部121的外周面上。将弹性接管142和插接头141分别密封连接于凸起部121的外周面和内壁面上，使得弹性接管142和插接头141与凸起部121之间连接面积大，实现连接方便，且连接强度高。其中，插接头141螺纹连接于凸起部121内，弹性接管142通过紧箍连接于凸起部121的外周面上，弹性接管142通过紧箍连接于连接管143的的外周面上，连接更加方便，且密封性能好。其中，插接头141可以通过锥型螺牙和密封生料带嵌设于凸起部121内并实现与安装座12的密封连接，连接非常方便，且连接强度高，密封状态良好，实现电连接装置的防水密封级别能够达到IP67以上。
在本实施例中，弹性接管142的两端分别通过紧箍分别密封套设于连接管143和凸起部121。当然，接插组件14也可以采用快插结构来实现连接，即弹性接管142的两端分别通过采用快插结构来分别实现与连接管143和凸起部121相连接。连接管143和凸起部121上也可以都安装有自锁结构，连接管143和凸起部121均通过自锁结构来实现与弹性接管142的安装连接，还是能够保证电连接装置的防水密封级别达到IP67以上。
连接管143穿过第一固定板11，连接管143的外周面上设有连接部144，连接部144连接于第一固定板11，弹性接管142密封连接于连接管143。连接部144从连接管143的外周面上沿接插组件14的径向方向向外延伸凸起，连接管143通过连接部144固定连接在第一固定板11上，连接方便。
弹性接管142的两端分别密封连接于连接管143和安装座12并与连接管143和插接头141相连通，且连接管143、弹性接管142和插接头141均用于冷源通过。接插组件14在密封状态时，连接管143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143、弹性接管142和插接头141，之后冷源通过电连接插座2的插接座23流向至电池包内来实现对电池包的冷却。
电连接器插头还包括有环形密封圈15，环形密封圈15套设于安装座12和第一固定板11，且环形密封圈15的内壁面的两侧分别连接于安装座12和第一固定板11。环形密封圈15具有密封效果，环形密封圈15采用环抱式分别连接具有间隙的安装座12和第一固定板11，使得安装座12与第一固定板11之间能够实现浮动连接，保证了安装座12的弹性复位，且有效加强了电连接插头1的密封效果。同时，电连接装置在使用时，环形密封圈15将会密封抵靠于第二固定板21上，环形密封圈15与电连接插座2之间实现密封，使得电连接装置防水密封性能良好。其中，安装座12与第一固定板11之间可以在四个角处均设有蝶形弹簧，通过蝶形弹簧进一步保证了安装座12的弹性复位。
环形密封圈15内还具有若干个分隔部，若干个分隔部的两端均连接于环形密封圈15并将环形密封圈15内的空间分隔形成若干个密闭空间，分隔部用于密封抵靠于第二固定板21上，以使若干个密闭空间不连通。通过分隔部能够将安装在安装座12上的电连接组件13与接插组件14相隔离，从而实现电连接装置的电连接与水连接相互隔离，进一步保证了电连接的安全稳定性。
电连接组件13包括有导电极柱131、柔性导电件132和导电插头133，导电极柱131穿设于安装座12，导电插头133穿设于第一固定板11，柔性导电件132的两端分别连接于导电极柱131和导电插头133。电连接组件13通过导电极柱131连接于电连接插座2的电连接件22实现电连接，同时，柔性导电件132自身能够产生形变，使得通过柔性导电件132实现导电插头133与导电极柱131之间实现浮动电连接，电连接装置在电连接时，导电极柱131能够与电连接件22一同移动，有效避免电连接失效，大大增强电连接装置在电连接时的可靠性及使用寿命。
柔性导电件132可以包括有弹性导电线，弹性导电线的两端分别连接于导电极柱131和导电插头133。弹性导电线具有弹性并能够与导电极柱131、导电插头133实现电连接。
柔性导电件132也可以包括有导电弹簧，导电弹簧的两端分别连接于导电极柱131和导电插头133。导电弹簧自身能够产生形变，同时也能够与导电极柱131、导电插头133实现电连接。
柔性导电件132可以包括有腔体，腔体由柔性导电材料制成，且腔体的两端分别连接于导电极柱131和导电插头133。腔体可拉长或压缩以及径向扭转，可适应导电极柱131与导电插头133之间轴向、径向等各个角度的相对位移变化，避免因相对位移的变化而导致电连接组件13电连接性能变差，大大提高了电连接装置在电连接时的稳定性。其中，腔体可以为由多个柔性导电条围成类球形的弹性腔体，腔体也可以为由网格状的柔性导电件围成类球形的弹性腔体，腔体还可以为由金属导线交叉编制而成类球形或为金属导电带扩拉而成类球形的弹性腔体。
在本实施方式中，电连接组件13和电连接件22的数量不作限定，电连接组件13和电连接件22可以分别为低压插座和低压插头、高压插座和高压插头，高压插座与高压插头相配合，低压插座与低压插头相配合。其中，电连接装置在电连接的过程中可通过低压控制高压的原理，也就是电连接插头1与电连接插座2之间在电连接的过程中，高压插座与高压插头之间的连接先于低压插座与低压插头之间的连接，在低压插座与低压插头接触完好后方可实现高压插座与高压插头之间接触通电；电连接插头1与电连接插座2之间在拆卸的过程中，低压插座与低压插头之间的断开先于高压插座与高压插头之间的断开，低压先断开即控制高压强制断电，有效避免在拆卸的过程中高压插座与高压插头之间出现电拉弧等不良现象，大大提高了电连接装置在电连接时的安全可靠性。
接插组件14中朝向插接座23的一端具有插接头141，插接座23套设于插接头141并能够在插接头141上沿插接头141的长度方向上移动，且插接座23与插接头141相连通。插接座23套设于插接头141并能够沿插接头141的长度方向上移动，插接座23和插接头141能够起到定位作用，电连接插头1通过插接头141插入至电连接插座2的插接座23内，能够实现电连接装置精准的水连接，且保证了水、电连接精度。同时，可以省略了在电连接插头1与电连接插座2之间设置定位销和定位套等结构，降低了成本。
插接头141和电连接组件13均露出于安装座12中朝向第二固定板21的侧面，且插接头141与插接座23之间先于电连接组件13与电连接件22之间相连接。电连接插头1与电连接插座2在连接的过程中，插接头141先插入至插接座23内，通过插接座23和插接头141的定位作用下，使得之后的电连接组件13与电连接件22之间精准连接，有效避免过多的定位结构使用，解决定位结构之间互相较劲问题，保证了电连接装置的水、电连接精度，提高了使用寿命，并且降低使用成本。同时，在插接座23与插接头141之 间连通之后电连接组件13与电连接件22才相连接，使得水连接之后才能够电连接，电连接之后才会提供冷却水循环使用，有效避免了冷却水发生渗漏现象。当然，电连接插头1与电连接插座2在断开时，电连接组件13与电连接件22之间先断开之后，插接座23与插接头141之间才会断开，使得插接座23与插接头141之间在断开之前不再提供冷却水，进一步避免了冷却水的渗漏现象。其中，电连接装置在水、电连接组合应用时，可针对电连接组件13与电连接件22之间的电连接进行检测，即对低压信号端子进行信号检测来控制实际车辆水冷却泵的开关控制，有利于实际对液冷却瞬漏后产生气泡等不良问题的控制。
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。
