AI Technical Summary
Existing contact charging connectors suffer from insufficient bonding force, low connection strength, poor structural stability, and low molding precision, resulting in loose components, poor adaptability, and affecting the normal implementation of charging functions and user experience.
The design employs a two-stage injection molding process, with the first and second molded parts tightly integrated. Combined with the positioning hole and positioning groove structure, the connection strength is enhanced. Nickel plating and powder metal materials improve the corrosion resistance and conductivity of the pins. The positioning accuracy and stability are improved by using limiting protrusions and injection molding process.
The structural stability and molding precision of the contact charging connector have been improved, ensuring the reliability of the charging connection and user experience, reducing the risk of component misalignment, and enabling normal charging function of smart products.
