Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular discloses an SMD spring structure. Background Technology

[0002] With the continuous trend towards miniaturization and integration of electronic devices, SMD springs, as crucial connecting components, significantly impact the stability and reliability of these devices. Traditional SMD spring elastic structures present numerous problems in practical use. For example, when existing SMD springs are electrically connected to contact points and subjected to downward pressure, the asymmetrical stress distribution causes the top of the spring to shift, resulting in the spring tilting outwards. This leads to a higher frequency of tilting under random vibration, making the system unstable. Some structures have limited elastic deformation capacity, easily experiencing elastic decay after external impact or long-term use, leading to unstable electrical connections. Other structures have poor installation adaptability, failing to meet the needs of different device sizes. Furthermore, traditional structures are not space-efficient and cannot fully adapt to the layout requirements of compact electronic devices. These problems severely restrict further improvements in electronic device performance; therefore, a new type of SMD spring elastic structure is urgently needed to solve these technical challenges.
