The present invention discloses a connector and a connector assembly. The connector comprises a housing, a connection assembly, a safety cover and a high-voltage interlock. During mating the connector with the mating connector, when the connection assembly is not fastened, the connection assembly is in a position of interference with the safety cover to prevent the safety cover from being moved from an initial position to a safety position. The safety cover and the high-voltage interlock are slidably connected. When the safety cover is moved to the initial position, the high-voltage interlock is moved to a disconnected position, and when the safety cover is moved to the safety position, the high-voltage interlock is moved to a connected position. The high-voltage interlock is separated from the mating high-voltage interlock before the terminal is electrically connected with the mating terminal, improving use safety of the connector.
