摘要： Proposed are a connector assembly and a battery module. The connector assembly may include a connector formed so that an external connector is inserted therein through a connector insertion portion formed in a casing, and a cover part coupled to the connector while surrounding an outer peripheral surface of the connector so as to seal a gap between the connector and the connector insertion portion. Accordingly, it is possible to block or delay discharge of a flame through the connector insertion portion of the battery module.

摘要： Proposed is a battery pack. The battery pack includes a battery module in which an internal terminal is exposed at an opening part, and a flame blocking unit which is connected to the internal terminal via the opening part and which transmits electric power of the internal terminal to the outside, the flame blocking unit covering the opening part so that a flame generated inside the battery module is blocked from being emitted. The battery module may include a battery assembly including a plurality of battery cells, a busbar assembly including the internal terminal which is connected to the battery assembly and which transmits electric power, and a casing which accommodates the battery assembly and the busbar assembly therein and in which the opening part is formed. By this configuration, thermal runaway of the battery module may be blocked or delayed, so stability of the battery pack may be increased.
