[0012] Beneficial effects:

[0013] 1. In existing technologies, while improving the performance of rugged phones by using high-capacity batteries exceeding 20,000 mAh and supporting 120W fast charging, increasing the thickness of the flexible printed circuit (FPC) to 0.25mm and widening it to 7mm to enhance circuit support or other design considerations, while bringing some structural stability improvements, also introduces a series of production and practical problems. The thickened and widened FPC becomes relatively rigid, losing the flexibility inherent in flexible boards. This makes it difficult for the FPC to fit smoothly into the complex internal space of the device during assembly, easily leading to creases, deformation, or even breakage due to improper handling. Especially in rugged phones, where sealing and durability are extremely important, damage to the FPC not only affects the phone's waterproof and dustproof performance but also causes instability in the internal circuitry, thus impacting the overall performance and lifespan of the phone. From a production and assembly perspective, the rigider FPC increases assembly difficulty and time costs, reduces production efficiency, and sometimes even requires specialized tools or techniques to avoid damage. This increases production costs and management difficulty. Furthermore, the hardened FPC is easily damaged by improper handling during subsequent maintenance and disassembly, leading to increased repair costs and further impacting product maintainability and user satisfaction. Additionally, accommodating the hardened FPC requires redesigning the phone's internal structure, occupying limited assembly space. This poses a significant challenge for rugged phones aiming for a compact layout. To address these issues, this invention employs an L-shaped bend design. The FPC for the high-capacity fast-charging battery in rugged phones is thicker and wider than ordinary batteries, making it prone to deformation, springback, or breakage during bending, and causing pulling damage during assembly and disassembly. The battery FPC is designed with an L-shaped bend at the bottom of the battery, away from the connector end, allowing for better fit with the edge of the fast-charging battery body and preventing damage. Furthermore, the FPC's design with the cable exit point away from the connector end enables effective pulling during assembly, reducing battery defects. The assembly structure does not require additional space, thus improving equipment lifespan and operability.

When the staff tries to place the battery accurately and correctly to the specified position, it is found that due to the elastic properties of the connector end 201, it is often difficult to achieve close fitting between the connector end 201 and the battery surface.
