Plug-in installation device and method for inserting cable assembly into housing

The invention discloses plug-in mounting equipment and a method for plugging a cable assembly into a shell. The plug-in mounting equipment comprises a cable control module and a shell control module. The cable control module comprises a terminal clamping device used for clamping two terminals; and the core wire clamping device is used for clamping the two core wires. The shell control module comprises a shell clamping device which is used for clamping the shell in the process that the two terminals are inserted into the shell. In the process of inserting the parts, except the root parts, of the two terminals into the shell, the terminal clamping device is clamped on the root parts of the two terminals, and the core wire clamping device is in an open state without clamping the two core wires; in the process of inserting the roots of the two terminals into the shell, the terminal clamping device is in an open state without clamping the two terminals, and the core wire clamping device is clamped on the roots of
