Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional connectors face challenges in managing crosstalk of differential signals at high frequencies and high densities, leading to signal integrity issues and increased weight due to excessive shielding and grounding materials.
Innovation Solution
The solution involves selectively disposing wave-absorbing materials in high-frequency radiation areas generated by the antenna effect during connector use, allowing for targeted absorption of crosstalk signals without affecting normal signals, thus eliminating the need for additional shielding materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shielding materials and grounding materials are used to solve crosstalk of differential signals, then signal integrity is improved, but connector weight increases
Solution Approach 1:
The patent applies local quality by selectively disposing wave-absorbing material only in high-frequency radiation areas where crosstalk occurs, rather than using shielding materials throughout the entire connector. This localized approach absorbs electromagnetic waves only where needed, maintaining signal integrity while minimizing unnecessary material usage and weight increase.
Solution Approach 2:
The patent converts the harmful electromagnetic radiation causing crosstalk into a beneficial effect by using wave-absorbing material to absorb these waves. The wave-absorbing material transforms the harmful electromagnetic energy into heat or other non-interfering forms, eliminating crosstalk without requiring traditional shielding structures that add weight.
2Reliability
If traditional shielding materials and grounding materials are used to solve crosstalk of differential signals, then signal integrity is improved, but device complexity increases
Solution Approach 1:
The patent simplifies device complexity by replacing complex traditional shielding structures with a simpler wave-absorbing material disposal approach. Instead of implementing extensive grounding pins, metal shields, and plastic enclosures, the invention uses wave-absorbing material selectively placed in high-frequency radiation areas, reducing structural complexity while maintaining signal integrity.
3Reliability
If wave-absorbing material is used to absorb crosstalk electromagnetic waves, then signal integrity is improved, but material cost increases
Solution Approach 1:
The patent optimizes material usage by disposing wave-absorbing material only in specific high-frequency radiation areas where crosstalk occurs, rather than using it throughout the entire connector. This selective localization minimizes the quantity of wave-absorbing material required while effectively maintaining signal integrity in critical areas.

AI summary
An exemplary female connector includes a plurality of female terminals having ends radially expanded outward to form trumpet-shaped guide heads for blind mating with a male connector or a gold finger circuit board. A first high-frequency radiation area is formed in the vicinity of the trumpet-shaped guide head when the female terminals are mated with the male connector or the gold finger circuit board. A first wave-absorbing material is disposed in a spatial scope covered by the first high-frequency radiation area.
