[0002] Generally speaking, there is not enough space on the upper end of the FPC reinforcement plate to make a separate handle. In order to facilitate customers to plug and unplug the FPC 100, two ears 110 are usually added to the FPC. In conventional designs, the reinforcement 200 on the back of the FPC is the same size as the ears 110, which easily causes the rounded corners to tear during plugging and unplugging.

[0003] Chinese utility model patent document CN206461820U discloses a tear-proof FPC board including an FPC board body, the FPC board body including, from bottom to top, a first covering film layer, an FPC layer and a PI layer, a second covering film layer is provided on the PI layer, the second covering film layer partially covers the PI layer, a PI reinforcement layer is provided on the second covering film layer, the PI reinforcement layer partially covers the second covering film layer. The thickness of the FPC layer is 0.05 mm. The PI reinforcement layer is 2-5 mm shorter than the second covering film layer. A tear-proof copper wire is provided on the area where the PI layer does not cover the second covering film layer. A reinforcing steel sheet is provided on the lower surface of the PI reinforcement layer. The FPC layer is L-shaped. A tear-proof copper wire is provided at the outer chamfer of the L-shape. A tear-proof copper wire is provided at the inner chamfer of the L-shape. The PI reinforcement layer is made of copper sheet material. The PI reinforcement layer is glued to the second covering film layer.

[0004] Obviously, the patent adds a layer of CVL to reinforce the PI reinforcement and FPC copper foil gap to increase the tear resistance of this position, so that customers will not be torn at this position when using it, causing assembly problems. The manufacturing cost of this technical solution is too high and requires many additional processes.

[0005] Chinese utility model patent document CN208636818U discloses a touch screen with tear-proof FPC, including a touch panel, a panel driver chip, and an FPC connecting wire for connecting the touch panel and the panel driver chip, the FPC connecting wire is tightly attached to the left side of the back of the touch panel, the panel driver chip is clamped on the end of the FPC connecting wire away from the touch panel, the top middle position of the FPC connecting wire is an FPC groove, the front of the FPC connecting wire is fixedly connected to a copper coil, the top edge of the copper coil is tightly attached to an outer edge line, the copper coil and the outer edge line are located directly below the FPC groove, the lower end face of the FPC connecting wire is tightly attached to an electromagnetic shielding film, the upper end face of the electromagnetic shielding film is fixedly connected to a reinforcing plate, and the upper end face of the reinforcing plate is tightly attached to a copper foil substrate. The upper and lower end faces of the FPC connecting wire are tightly attached to a PI protective film, and the area of ​​the PI protective film is larger than the area of ​​the FPC connecting wire. The upper end surface of the copper foil substrate is fixedly connected with an adhesive, and the upper end surface of the adhesive is tightly attached to the PI protective film. The outer side wall of the touch panel is tightly attached to a frame, and a graphic button is tightly attached to the middle position of the front lower side of the frame, and there are three graphic buttons in total, and the three graphic buttons are respectively a menu button, a main interface button and a return button from left to right. The upper end surface of the touch panel is tightly attached to a PET protective film, and the lower end surface of the PET protective film is fixedly connected to a PET panel, and the lower end surface of the PET panel is tightly attached to the front ITO of the touch sensor, and the lower end surface of the front ITO of the touch sensor is fixedly connected to the back ITO of the touch sensor, and the gap between the front ITO of the touch sensor and the back ITO of the touch sensor is tightly attached to a glass substrate. The lower end surface of the touch panel is tightly attached to a foam glue, and the upper end surface of the foam glue is fixedly connected to a double-sided tape, and the upper end surface of the double-sided tape is tightly attached to the lower end surface of the back ITO of the touch sensor. The upper end surface of the copper foil substrate is fixedly connected with a flat cable, and the upper end surface of the flat cable is tightly attached to the adhesive.

[0006] Obviously, in this patent, a copper coil is fixedly connected to the front of the FPC connecting line, and the top edge of the copper coil is tightly fitted with an outer edge line. The copper coil and the outer edge line are located directly below the FPC groove, one end of the outer edge line is located outside the FPC groove, and the other end is fixedly connected to the FPC connecting line. The outer edge line and the copper coil are used to reinforce the side of the FPC groove close to the FPC connecting line, which avoids the situation that the FPC connecting line is torn when an external force acts on the outside of the FPC groove, thereby ensuring the integrity of the FPC connecting line. In addition, in this patent, an electromagnetic shielding film is tightly fitted to the lower end surface of the FPC connecting line, and the electromagnetic shielding film is located at the lower end of the FPC connecting line. By placing the side with the electromagnetic shielding film close to the touch panel, the electromagnetic waves emitted by the touch panel during operation are prevented from affecting the signal transmission inside the FPC connecting line, thereby enhancing the stability of the signal transmission of the FPC connecting line. This technical solution can only prevent the situation that the FPC connecting line is torn when an external force acts on the outside of the FPC groove, and cannot prevent the ear position of the FPC from being torn.
