Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple conductive terminals are used to transmit high-speed signals, then signal transmission capability is improved, but electromagnetic interference and crosstalk increase
Solution Approach 1:
A grounding terminal pin bridging structure is introduced as an intermediary element between the non-grounding terminal pin and the grounding terminal pin. This bridging structure provides a dedicated shielding path that mediates the electromagnetic field interactions, reducing crosstalk and interference while maintaining high-speed signal transmission capability through multiple conductive terminals
Solution Approach 2:
The electrical connector implements local quality differentiation by providing specialized grounding structures (bridging structure and grounding terminal pin) specifically positioned to shield the non-grounding terminal pin. This localized shielding approach targets the specific interference problems in high-speed signal transmission zones without affecting the overall signal transmission performance of other terminals
2Reliability
If grounding terminal pin bridging structure is added to connect first and second grounding terminal pins, then shielding effect is improved, but device complexity increases
Solution Approach 1:
The grounding terminal pin bridging structure merges multiple grounding functions into a single integrated component. It simultaneously connects the first grounding terminal pin and the second grounding terminal pin, providing comprehensive shielding for the non-grounding terminal pin from multiple directions. This merging approach enhances shielding reliability while avoiding the complexity of separate grounding structures for each terminal
