AI Technical Summary

Technical Problem

In existing electrical connectors, the terminal structure design leads to an increase in height, which is not conducive to the development of ultra-thin electrical connectors, and the solder balls are prone to detachment, resulting in poor stability.

Method used

The V-shaped bent section abuts the solder ball, and the stop block prevents the terminal from moving upward, reducing the terminal height. At the same time, the guide surface and the stop block ensure that the solder ball is stably fixed.

Benefits of technology

This achieves stable contact of the solder balls, prevents detachment, reduces terminal height and volume, and improves assembly stability and solderability.

Abstract

The application discloses an electric connector, comprising: an insulating body with a plurality of accommodation grooves penetrating in the up-down direction, each of the accommodation grooves is provided with a stopper; a plurality of terminals and tin balls are respectively accommodated in the accommodation grooves, the terminal has a flat plate part, two first welding parts extending downward and in parallel, the flat plate part is coplanar with the two first welding parts, an accommodation groove is formed between the two first welding parts, the lower ends of the two first welding parts extend to two second welding parts, the ends of the two second welding parts are respectively bent to form a bent part away from the direction of the tin ball, the plate surface of the bent part towards the tin ball is defined as a matching surface, the gap between the two matching surfaces of each terminal is smaller in the direction away from the tin ball, the tin ball is partially accommodated between the accommodation groove and the two matching surfaces, the matching surface abuts against the tin ball and is located below the horizontal center surface of the tin ball, the stopper downwardly stops the bent part to prevent the terminal from moving upward, the terminal forms a V-shaped structure to abut against the tin ball, and the tin ball is not easy to fall off.
