Abstract

The utility model proposes a connector assembly, a refrigerant connection pipeline and an energy storage system. The connector assembly includes a female connector and a male connector. The female connector and the male connector have a separation state and a plug-in state. In the separation state, the female connector and the male connector drive the valve core to disconnect the internal channel through the built-in elastic member, so that the flow path of the refrigerant is cut off, reducing the leakage of the refrigerant. In the plug-in state, the plug-in end of the male connector can be plugged into the first channel of the female connector, so that the male connector and the female connector are in a plug-in state. At this time, the valve cores of the male connector and the female connector abut against each other and move toward the inside of the connector, thereby making the internal channel of the male connector and the internal channel of the female connector connected to each other, so that the flow path of the refrigerant is connected, avoiding the refrigerant pipe from being connected by welding, causing damage to the energy storage system.
