AI Technical Summary
Existing electrical connectors require both the upper and lower contact ends to be pressed into place simultaneously to achieve dual-path connection when the terminals are pressed. Stable transmission cannot be achieved when the terminals are tilted or not pressed into place.
Design an electrical connector in which the terminal includes a retaining portion and first and second elastic arms, the elastic arms abutting against the same contact portion when pressed to ensure stable contact, and a terminal groove structure within an insulator is used to fix and guide the deformation of the elastic arms.
This ensures the stability of the electrical connector during multi-path transmission, avoids connection failures caused by misalignment of the elastic arm, and improves transmission reliability.
