Electrical connector assembly

An electrical connector assembly for electrically connecting an external circuit board, comprising:

• an insulating main body;
• a first connector module disposed inside the insulating main body and electrically connected to the external circuit board;
• at least one second connector module disposed inside the insulating main body and located above the first connector module;
• and
• a flexible conducting wire having two ends electrically connected to the second connector module and the external circuit board, respectively;
• wherein the second connector module further including an internal circuit board and a terminal group electrically connected to the external circuit board, and the internal circuit board has a plurality of connection terminals, the terminal group has a conduction board having connection terminals;
• wherein the flexible conducting wire is disposed outside of the insulating main body, two ends of the flexible conducting wire are electrically connected to the internal circuit board and the connection terminals respectively.
