随着新能源行业的快速发展，对电池产品(如电池包或高压盒)的操作界面的便捷要求不断提高，运用频率最高的手动维护开关(MSD，Manual Service Disconnect)首先被考虑。MSD通常包括熔断器、插座(包括底座和插座端子)和插头(包括基座和插头端子)，且MSD通过插头端子和插座端子之间的插接或断开来实现电池产品中的高压电连接的通断。
传统的MSD将熔断器集成在插头上，随着电池产品对电流的要求越来越大，为了保护电池产品中的电池，熔断器的体积也越来越大，这使得插头的体积越来越大、重量越来越大，从而增大了插座与插头之间的装配难度。

参照图2至图12，多功能高压连接器2可包括熔断器21、插座22、插头23、第一转接片24、第一线束组件25、第二转接片26、安装座27、第二线束组件28、第一盖板2A、第二盖板2B、第三盖板2C、密封垫2D、第一密封圈2E、第二密封圈2F以及第三密封圈2G。
为了实现电池产品内部与外部之间的电连接，参照图2，电池集合体的第一输出极通过多功能高压连接器2的第一线束组件25电连接于电池产品外部的其它装置，第二输出极通过多功能高压连接器2的第二线束组件28电连接于电池产品外部的其它装置，由此电池集合体的第一输出极、第二输出极以及第一线束组件25、第二线束组件28与所述其它装置一起形成高压连接电路。其中，所述其它装置可为另一电池包或高压盒。
参照图1，多功能高压连接器2的插座22固定安装于箱体1，插头23用于与插座22插接或断开插接，从而控制所述高压连接电路的通断。

在多功能高压连接器2中，插座22与插头23构成多功能高压连接器2的通断连接部分，熔断器21构成多功能高压连接器2的电路保护部分。其中，多功能高压连接器2的通断连接部分控制所述高压连接电路的通断，而电路保护部分对所述高压连接电路进行过载保护。
由于多功能高压连接器2的通断连接部分与电路保护部分独立设置，因而插头23的体积和重量与熔断器21无关，当需要闭合或断开多功能高压连接器2的通断连接部分时，只需将插头23与插座22插接或断开插接即可。因此，基于熔断器21与插头23、插座22之间的位置关系，使得插头23的体积小、重量轻，从而便于插头23与插座22之间的装配，由此提高了电池产品的装配效率。当电池产品需要维护时，直接将插头23从插座22上拔下即可，操作简单、且省时省力，提高了维护效率。此外，由于插头23与插座22之间的装配简单，从而有助于减少因操作不当而带来的电连接失效风险。

参照图6、图7和图10，安装壳体223还可具有：第三延伸部2235，沿厚度方向T突出于第三主体部2231。安装座27的第五主体部271位于安装壳体223的第三主体部2231的背向第三延伸部2235的一侧，第五收容部272收容于第三延伸部2235。其中，第二线束组件28固定于安装壳体223的第三延伸部2235且第二线束组件28的部分位于安装座27的第五收容部272中，以连接于第二转接片26的第三端部261。
参照图10，安装壳体223的第三延伸部2235可设置有第三凹槽22351。第三盖板2C装配于第三延伸部2235，第三密封圈2G收容于第三凹槽22351中并密封连接第三盖板2C与第三延伸部2235。
参照图8和图9，第一互锁结构224固定安装于底座221并接入到电池产品的电池管理系统(BMS)中。参照图11，第二互锁结构234固定安装于基座231，当基座231插接于底座221的第二收容部2213时，第二互锁结构234插接于第一互锁结构224，此时第二互锁结构234、第一互锁结构224以 及BMS形成低压互锁电路。低压互锁电路对电池产品的高压连接电路起到保护作用，由此保证了电池产品的可靠性和安全性。
参照图3，密封垫2D设置于插头23的基座231与安装壳体223的第三主体部2231之间以密封连接插头23和插座22。
这里需要说明的是，由于多功能高压连接器2的通断连接部分与电路保护部分独立设置，因而通断连接部分(通过密封垫2D密封)和电路保护部分(通过第一盖板2A和密封第一密封圈2E密封)分别单独密封，由此减小了各自的密封面，大大提高了密封效果。
