Installation structure of sunken fpc connector

A Flexible Printed Circuit (FPC) assembly, comprising:

• an FPC connector, comprising:
• an insulating plastic base, the insulating plastic base is provided with an insertion slots, and a plurality of insertion holes are provided in the insertion slots;
• a shell, comprising a top plate, a bottom plate and a connecting plate, the connecting plate is arranged between a rear end of the top plate and the bottom plate, and the shell having two opposite first sides and two opposite second sides, wherein the bottom plate comprises a first bending fixed arm and a second bending fixed arm, which respectively extend from the two first sides;
• wiring terminals, in plug-in connection with the insertion holes;
• and
• a flexible flat cable, in plug-in connection with the insertion slots;
• and
• a circuit board, provided with an installation port adapted to an outer contour of the FPC connector;
• wherein, when the circuit board is inserted into the FPC connector, and after the FPC connector is in abutting contact with the installation port, the circuit board is connected with the first bending fixed arm and the second bending fixed arm by welding, respectively, thereby realizing the connection and fixation between the FPC connector and the circuit board.
