[0002] As an elastic material made of metal, metal elastic sheets are widely used in many fields, demonstrating their excellent performance and versatility. These fields include, but are not limited to, industrial fields such as construction, automotive, aerospace, and electronic products. Metal elastic sheets serve as power transmitters to support machines and equipment. In the mobile phone field, their application is even more indispensable. Metal elastic sheets are widely used in key components such as mobile phone cards, mobile phone antennas, membrane switches, touch switches, PCB boards, and FPC boards. As an important component for connection and conduction, they ensure the stable transmission of mobile phone signals and the normal operation of circuits. The high precision and stability of metal elastic sheets also play a crucial role in enhancing the user experience.

[0003] In the mobile phone field, metal elastic sheets are usually designed as thin and delicate sheet structures to adapt to the compact internal space layout of mobile phones. They are manufactured through precise stamping and bending processes to ensure dimensional accuracy and shape stability. In mobile phone touch switches, metal elastic sheets achieve on-off control of circuits through their elastic deformation. As a key component for connection control of electronic components, the stability and strength of their connections are important factors affecting service life.

[0004] However, although existing metal elastic sheets are widely used inside mobile phones, due to the relatively fast replacement speed of electronic products, the internal structure of mobile phones also changes accordingly. Therefore, some metal elastic sheets have problems of insufficient precision and installation and use strength in the design and manufacturing processes, resulting in phenomena such as poor contact and unstable signal transmission during use, as well as poor installation and limiting effects on internal components, leading to poor durability of metal elastic sheets, thus affecting the service life of the elastic sheets and the stable use of mobile phones.
