Engineering Contradiction Analysis
1Reliability
If a grounding piece with multiple ground terminals is provided to reduce interference during data transmission, then shielding performance is improved, but the structure becomes more complicated and manufacturing becomes difficult
Solution Approach 1:
The grounding piece is segmented into multiple grounding tabs (first grounding tab and second grounding tab) that are distributed on different sides of the insulating body. Each grounding tab independently contacts with corresponding ground terminals, achieving comprehensive shielding while maintaining a relatively simple overall structure.
Solution Approach 2:
Different grounding tabs are positioned at specific locations (first grounding tab on one side, second grounding tab on another side) to provide localized shielding where interference is most likely to occur. This targeted approach improves shielding effectiveness without requiring a complex grounding structure throughout the entire connector.
2Reliability
If a grounding piece with multiple ground terminals is provided to reduce interference during data transmission, then shielding performance is improved, but manufacturing becomes more difficult
Solution Approach 1:
The grounding piece is divided into multiple independent grounding tabs that can be manufactured separately and then assembled or integrated into the insulating body. This segmentation allows for simpler manufacturing processes for each individual tab while achieving comprehensive shielding when combined.
Solution Approach 2:
The grounding tabs serve multiple functions: they provide shielding for different signal transmission paths, act as structural support elements, and facilitate assembly with the insulating body. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing.

AI summary
An electric connector includes an insulating body, a first terminal module, a second terminal module and a grounding piece. The first terminal module includes a number of first conductive terminals each having a first tail portion. The second terminal module includes a number of second conductive terminals each having a second tail portion. The ground piece includes a first grounding tab and a second grounding tab. The first conductive terminals include a first ground terminal. The second conductive terminals include a second ground terminal. The first grounding tab is stacked on and in contact with the first tail portion of the first ground terminal. The second grounding tab is stacked on and in contact with the second tail portion of the second ground terminal. Such an arrangement simplifies the structure of the grounding piece, and can also realize a shielding function.
