High-Speed Connector Conductive Plastic Shielding
Solution Overview
Problem
High-speed connectors lack effective electromagnetic shielding at the point where cables pass through, making them vulnerable to interference during signal transmission.
Innovation Solution
A high-speed connector design that includes a conductive plastic layer on the back surface of the insulating body, which complements the existing shielding shell to provide comprehensive protection against electromagnetic interference by grounding the cables and metal shield components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding shell is used to provide electromagnetic shielding, then shielding performance is improved, but the back surface where cables pass through remains vulnerable to interference
Solution Approach 1:
The patent applies local quality by adding conductive plastic material specifically at the back surface where cables pass through, rather than uniformly shielding the entire connector. This targeted approach addresses the specific vulnerability zone without requiring complete redesign of the shielding structure.
Solution Approach 2:
The patent uses composite materials by combining conductive plastic with the existing shielding shell structure. The conductive plastic material complements the metal shielding shell, creating a multi-material shielding system that addresses both the general shielding needs and the specific cable passage vulnerability.
2Object-affected harmful factors
If conductive plastic is added to the back surface to improve shielding, then electromagnetic interference protection is enhanced, but device complexity increases
Solution Approach 1:
The patent merges the shielding function into the existing connector structure by integrating conductive plastic material with the insulating body and shielding shell. This combination approach adds shielding capability without requiring completely separate shielding components, thereby limiting the increase in device complexity.
