Abstract: A connector module includes an insulator with a terminal slot accommodating a terminal and a tool insertion port in communication with the terminal slot. A terminal locking member of the connector is installed on the insulator and movable between a pre locking position separated from the terminal and a final locking position engaged with the terminal. When the terminal locking member is in the pre locking position, the tool insertion port is not blocked by the terminal locking member to allow an operating tool to be inserted into the terminal slot through the tool insertion port to drive a locking spring of the terminal to an unlocking position separated from the insulator. With the terminal locking member in the final locking position, the tool insertion port is blocked by the terminal locking member to prevent the operating tool from being inserted into the terminal slot through the tool insertion port.
