第一导电组件15还包括柔性导电件152和导电插头153，导电极柱151的两端分别具有电接触端和接线端，电接触端露出于第一安装座12的外表面，柔性导电件152的一端与接线端之间浮动电连接，导电插头153穿设于固定板11，且导电插头153与柔性导电件152的另一端之间浮动电连接。电接触端露出于第一安装座12的外表面并便于与第二导电组件25之间实现电连接。同时，柔性导电件152自身能够产生形变，使得通过柔性导电件152实现导电插头153与导电极柱151之间实现浮动电连接，多功能连接器装置在电连接时，导电极柱151能够与第二导电组件25一同移动，有效避免电连接失效，大大增强多功能连接器装置在电连接时的可靠性及使用寿命。
在本实施方式中，第一导电组件15和第二导电组件25的数量不作限定，第一导电组件15和第二导电组件25可以分别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，多功能连接器装置在电连接的过程中可通过低压控制高压的原理，也就是电连接器插头1与电连接器插座2之间在连接的过程中，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；电连接器插头1与电连接器插座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，大大提高了多功能连接器装置在电连接时的安全可靠性。
第一安装座12与固定板11之间浮动连接。在本实施方式中，电连接器插头1通过固定板11安装于车体，电连接器插座2通过第二安装座21安装于电池端，固定板11将同时与第一安装座12、冷源接插头13之间浮动连接，电连接器插头1与电连接器插座2在水连接之后，冷源接插头13和第一安装座12能够随冷源接插座22一同移动，有效避 免了冷源接插头13与冷源接插座22之间水连接松动而发生液体外流、喷溅现象，大大提高了多功能连接器装置在水连接时的稳定性。
电连接器插头1还包括有环形密封圈17，环形密封圈17套设于第一安装座12和固定板11，且环形密封圈17的内壁面的两侧分别连接于第一安装座12和固定板11，环形密封圈17朝向电连接器插座2的一侧设有向外凸起的环形抵靠部171，环形抵靠部171连续不间断地环绕于环形密封圈17，且环形抵靠部171用于与电连接器插座2相抵靠。环形密封圈17具有密封效果，环形密封圈17采用环抱式分别连接固定板11和第一安装座12并与电连接器插座2实现密封，使得多功能连接器装置防水密封性能良好。同时，电连接器插头1与电连接器插座2之间通过环形密封圈17实现浮动式电连接，进一步保证电连接器插头1与电连接器插座2之间电连接的稳定性。
环形密封圈17内还具有若干个分隔部172，若干个分隔部172的两端均连接于环形抵靠部171并将环形抵靠部171内的空间分隔形成若干个密闭空间，分隔部172用于压设于第一安装座12与电连接器插座2之间，以使若干个密闭空间不连通。通过分隔部172能够将安装在第一安装座12上的冷源接插头13与第一导电组件15相隔离，从而实现多功能连接器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。
第二安装座21中朝向电连接器插头1的一侧设有环形密封槽24，环形密封槽24连续不间断地环绕于第二安装座21的四周外缘，环形密封槽24用于与电连接器插头1的环形密封圈17相连接。环形密封槽24与环形密封圈17之间相互配合，且环形密封圈17密封连接于环形密封槽24内，有效加强了电连接器插头1与电连接器插座2之间的密封性能，大大提高了多功能连接器装置的安全可靠性。
环形密封槽24内还具有若干个分隔槽241，若干个分隔槽241的两端均连接于环形密封槽24并将环形密封槽24内的空间分隔形成若干个密闭空间，分隔槽241用于与电连接器插头1的分隔部172相连接，以使若干个密闭空间不连通。分隔槽241与分隔部172之间相互配合，且分隔部172密封连接于分隔槽241内，进一步加强了电连接与水连接之间密封隔离效果，大大提高了多功能连接器装置在电连接时的安全稳定性。
第一安装座12上设有至少一个第一定位部16，第一定位部16的一端连接于第一安装座12中朝向电连接器插座2的一侧，第一定位部16的另一端沿靠近电连接器插座2的方向延伸凸起。第二安装座21上设有至少一个第二定位部23，第二定位部23的一端位于第二安装座21中朝向电连接器插头1的一侧，第二定位部23的另一端沿远离电连接器插头1的方向向内凹陷。第一定位部16和第二定位部23均具有导向定位作用，第一定位部16与第二定位部23之间相互配合，且第一定位部16插入至第二定位部23内， 使得电连接器插头1与电连接器插座2之间连接精度高，也就是冷源接插头13与冷源接插座22之间精确连通以实现水连接，第一导电组件15与第二导电组件25之间精确接触以实现电连接，提高了多功能连接器装置的稳定性。
在本实施方式中，第一定位部16为凸起结构，第二定位部23为凹陷结构，第一定位部16与第二定位部23之间相互配合，当然，在其他实施例中，只有第一定位部16与第二定位部23之间相互配合，也落入本发明的保护范围。比如第一定位部16的一端位于第一安装座12中朝向电连接器插座2的一侧，第一定位部16的另一端沿远离电连接器插座2的方向向内凹陷；第二定位部23的一端连接于第二安装座21中朝向电连接器插头1的一侧，第二定位部23的另一端沿靠近电连接器插头1的方向延伸凸起。第一定位部16为凹陷结构，第二定位部23为凸起结构，第一定位部16与第二定位部23之间相互配合，也同样能够提高电连接器插头1与电连接器插座2之间连接精度。
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。
