[0003] When some existing electronic components are installed, soldering is usually used for connection. However, the metal ends at the upper ends of electronic components are usually long and thin. When subjected to external forces, the metal ends will be bent, which is extremely unfavorable for the installation of electronic components. After installation, there may be problems such as shaking and bending, resulting in poor connection contact. For this reason, we propose a precise connection structure for electronic components.
