Electrical connector assembly

An electrical connector assembly, comprising:

• an insulator with a slot comprising a first wall and a second wall, with the first wall installed with a plurality of first slot holes and the second wall installed with a plurality of second slot holes;
• a printed circuit board (PCB) inserted in the slot, with one side of the PCB equipped with a plurality of first conductive parts facing the first wall, and the opposite side of the PCB equipped with a plurality of second conductive parts facing the second wall;
• a plurality of first terminals, embedded in the first slot holes of the insulator, with contacting parts of the first terminals extending into the first slot holes, and ends of the first terminals electrically connecting to the first conductive parts of the PCB;
• a plurality of second terminals, embedded in the second slot holes of the insulator, comprising a plurality of first contacting parts and second contacting parts, with the first contacting parts electrically connecting the second conductive parts of the PCB;
• and
• a flexible flat cable (FFC), comprising an insulating layer covering a plurality of conductors, with its end forming an inserting part, an overlapping part and a bending part that connects the inserting part and the overlapping part;
• wherein the insulator further comprises a cable slot, which connects the second slot holes so that the second contacting parts of the second terminals extend into the cable slot, wherein the opening direction of the cable slot is opposite to that of the slot;
• the FFC's inserting part inserted in the cable slot;
• the ends of the conductors electrically connect the second contacting parts of the second terminals.
