AI Technical Summary
The insertion and assembly process of traditional flexible printed circuit boards is complex, making it difficult to achieve stable holding and simple assembly.
An FPC connector was designed, including an insulating body, conductive terminals, a metal cover plate, and a reinforcing shell. Self-locking is achieved through the locking structure between the main body and protrusion of the reinforcing shell and the metal cover plate, simplifying the insertion and removal process.
It achieves stable holding and simplified assembly of FPC boards, improves the overall strength of FPC boards, and ensures the stability of the connection through a self-locking structure.

Abstract
Claims
1. An FPC connector for inserting an FPC board, the FPC connector comprising a laterally extending insulating body, a plurality of conductive terminals fixed within the insulating body, and a metal cover plate covering the insulating body, the insulating body having a bottom wall and two side walls extending upward from the lateral sides of the bottom wall, the lateral sides of the metal cover plate being fixed to the side walls, and the metal cover plate, the bottom wall, and the two side walls together forming a mating cavity, the FPC board being inserted into the mating cavity; characterized in that: The FPC connector includes a reinforcing housing fixed to the FPC board. The reinforcing housing covers the outside of the FPC board and has a main body portion covering the top surface of the FPC board and a protrusion portion extending upward from the main body portion. When the FPC board is fully inserted into the mating cavity, the main body portion of the reinforcing housing is located between the metal cover plate and the FPC board, and the protrusion portion is held in place by the metal cover plate.
2. The FPC connector according to claim 1, wherein: The reinforcing housing has a front covering portion that bends downward from the front end of the main body portion, and the front covering portion covers the front end of the FPC board.
3. The FPC connector of claim 2, wherein: The reinforcing shell has side covering portions that bend downward from both sides of the main body, and the side covering portions cover the lateral sides of the FPC board.
4. The FPC connector of claim 1, wherein: The metal cover plate has a top plate portion extending laterally and two side plate portions extending downward from both sides of the top plate portion. The top plate portion covers the top surface of the insulating body, and the side plate portions are integrally formed within the side wall.
5. The FPC connector of claim 4, wherein: The sidewall of the insulating body is injection molded onto the side plate portion of the metal cover plate.
6. The FPC connector of claim 4, wherein: The metal cover plate has a bottom plate portion that extends laterally outward from the bottom edge of the side plate portion. The bottom plate portion is exposed on the outside of the bottom wall and is welded to a circuit board.
7. The FPC connector of claim 1, wherein: The docking cavity opens toward the longitudinal front end of the insulating body, and the insulating body has a rear wall extending upward from the longitudinal rear end of the bottom wall, with the two transverse sides of the rear wall connected to the two side walls.
8. The FPC connector as described in claim 7, characterized in that: The conductive terminal includes a first terminal and a second terminal spaced apart laterally, and the first terminal and the second terminal are inserted in opposite directions longitudinally.
9. The FPC connector of claim 8, wherein: The first terminal is inserted into the insulating body from the longitudinal front end of the insulating body. The first terminal is provided with a first holding part fixed on the rear wall, a first contact part extending longitudinally forward from the first holding part into the mating cavity, and a first solder leg extending longitudinally forward from the first holding part out of the insulating body. A gap is formed between the first contact part and the first solder leg.
10. The FPC connector of claim 9, wherein: The second terminal is inserted into the insulating body from the longitudinal rear end of the insulating body. The second terminal is provided with a second holding part fixed on the rear wall, a second contact part extending longitudinally forward from the second holding part into the mating cavity, and a second welding leg extending longitudinally backward from the second holding part out of the insulating body. The first contact part and the second contact part are located at the same height, and the second contact part is located on the longitudinal rear side of the first contact part.
