AI Technical Summary

Technical Problem

The shielding effect of the plug end of the existing connector is poor, especially when the node density is small and the line width is wide, the conventional grounding shrapnel stamping method cannot spread material, resulting in poor shielding effect in the bending area of ​​the shielding sheet, and the shielding cannot be installed separately to improve the shielding effect.

Method used

The conductive shell and the grounding shrapnel are adopted. The conductive shell is equipped with a shrapnel mounting cavity and a terminal avoidance hole. The grounding shrapnel and the conductive shell can be installed separately. The conductive shell is used to install the grounding shrapnel together to make them conduct each other, and shielding is achieved through the conductive part of the conductive shell and the shielding sheet.

Benefits of technology

The shielding effect of the connector plug end is improved, the signal terminal is prevented from conducting with the conductive shell, the signal transmission performance is enhanced, and the forming and fixing process of the grounding shrapnel is simplified.
