Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electrical connectors experience crosstalk issues due to high-frequency signals when signal terminals are too close to each other, affecting signal transmission.
Innovation Solution
The electrical connector features an insulation body with signal and ground terminals arranged at intervals, along with conductive plastic on the tongue portion that comes into contact with the ground terminals of a butt plug, ensuring electrical conductivity and preventing crosstalk.

Engineering Contradiction Analysis
1Area of stationary object
If signal terminals are arranged close to each other to increase transmission bandwidth, then the transmission bandwidth is improved, but crosstalk phenomenon occurs affecting signal transmission
Solution Approach 1:
The patent introduces conductive plastic as an intermediary shielding layer between signal terminals and ground terminals. This conductive plastic layer acts as a mediator that redirects electromagnetic interference to the ground, preventing crosstalk between adjacent signal terminals while maintaining close spacing for high bandwidth transmission.
Solution Approach 2:
The patent applies conductive plastic material specifically at the tongue portion where ground terminals are located, creating localized electromagnetic shielding only where needed. This local application of conductive material provides targeted protection against crosstalk without affecting the overall signal transmission performance or requiring complete restructuring of the connector.
2Reliability
If ground terminals are added to prevent crosstalk, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
The patent combines the grounding function with the existing insulation body structure by integrating conductive plastic directly into the tongue portion of the insulation body. This merging approach allows the grounding system to be formed as part of the existing connector structure rather than as a separate additive component, thereby improving signal quality without proportionally increasing device complexity.
Solution Approach 2:
The patent uses composite conductive plastic material that combines insulating plastic with conductive fillers to create a material that can provide both structural support and electromagnetic shielding functionality. This composite material approach allows a single component to serve multiple functions (structural + grounding + shielding), reducing the need for additional separate grounding components and simplifying the overall device structure.
