When the screen 101 of the three-proof mobile phone needs to be assembled or disassembled, the shorter connection line may cause the technician to take a specific posture or use special tools to ensure the stability of the connection line during the operation, which not only increases the difficulty of maintenance, but also leads to improper operation. Secondly, the shorter connection line is easily affected by the pulling force during the assembly or disassembly process, which will cause physical damage to the interface of the connection line and may even cause the internal circuit to break, thereby affecting the normal use of the mobile phone. The solution is to install the N-shaped connection line 204 to achieve the design of the flexible printed circuit board Flexible When assembling and disassembling the FPC, an N-shaped cable design is adopted. This design allows the FPC to be effectively stretched during the disassembly process for easy operation. At the same time, after the assembly is completed, this design will not take up too much assembly space, thereby ensuring the compactness of the equipment. This N-shaped cable design also helps to improve the production process, which makes the assembly and disassembly process more convenient. Since the N-shaped cable design of the FPC can be stretched, engineers can easily operate during assembly or maintenance without worrying about damage to the FPC or the cable. In addition, this design is also conducive to protecting the display screen, because during the disassembly process, the N-shaped cable design will not be excessively bent or twisted, thereby avoiding possible damage to the display screen. At the same time, the lower edge 206 facilitates the device to position the N-shaped connecting line 204, and the connecting line is positioned and fixed through the lower side groove 202, thereby improving the yield rate, achieving the effect of improving production efficiency, reducing maintenance difficulty, and extending the service life of the product.An upper groove 203 is provided on the front of the wiring board 102, and an upper edge 205 is fixed on one side of the N-shaped connecting wire 204.

When installing the N-shaped connecting wire 204, the end of the N-shaped connecting wire 204 connected to the circuit board 103 is long, which is difficult for the staff and process equipment to control during installation, causing the end to slip easily during production. The upper edge 205 is installed to solve the problem. When the staff installs, the upper edge 205 is placed in the upper groove 203 and then fixed by gluing, so that it is convenient for the staff to temporarily fix the cable during installation. After the installation is completed, the cable is fixed by the pressure between the parts to avoid affecting the disassembly and assembly.

The installation of the ring edge 3 is used to solve the problem. Before the staff installs the screen 101, the waterproof glue is applied to the ring edge 3, and then the screen 101 and the ring edge 3 are compacted, so that the waterproof glue prevents water from entering the screen 101, reducing costs while achieving a waterproof effect, thereby reducing production costs. The bottom end of the fixed bottom line 207 is set as a single-layer area 301. The single-layer area 301 adopts a simple structure of a single-layer cable to make wiring easy, convenient for quick installation and connection. Since the single-layer cable is thin, it can be wired in a limited space, which helps to reduce the volume and weight of the device. The fixed bottom line 207 is set as a fixed area 209. By setting the fixed area 209, the fixed bottom line 207 is prevented from being bent, thereby protecting the device and increasing the service life of the device.

[0026] The working principle of the utility model is as follows: when designing the flexible printed circuit board (FPC) of the display screen, an N-shaped cable design is adopted. This design method allows the connecting wires of the FPC to be effectively stretched during the disassembly and assembly process. During the disassembly and assembly process, the N-shaped cable design will not be excessively bent or twisted, thereby avoiding possible damage to the display screen. At the same time, the lower edge 206 facilitates the device to position the N-shaped connecting wire 204, and the connecting wire is positioned and fixed through the lower side groove 202. When the staff installs it, the upper edge 205 is placed in the upper side groove 203, and then fixed by gluing, so as to facilitate the staff to temporarily fix the cable during installation. When the installation is completed, the cable is fixed by the pressure between the parts to avoid affecting the disassembly and assembly.
