Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If communication signal speed is increased, then data transmission efficiency is improved, but electromagnetic noise and coupling between transmission lines increase
Solution Approach 1:
The connector is divided into multiple holders (first holder, second holder, third holder, fourth holder) that physically separate different signal transmission lines. This segmentation prevents electromagnetic coupling between adjacent transmission lines while maintaining high-speed signal transmission capability.
Solution Approach 2:
Electrically conductive partition walls are selectively positioned between specific transmission lines to provide localized electromagnetic shielding. The partition walls create grounded shielding regions around high-speed signal paths, reducing noise without requiring complete enclosure of the entire connector.
2Object-affected harmful factors
If electrically conductive partition walls and shielding structures are added, then electromagnetic noise is reduced, but device complexity increases
Solution Approach 1:
The holders serve multiple functions: they provide mechanical support for contacts, provide electrical insulation between different signal lines, and when combined with partition walls, provide electromagnetic shielding. This multi-functionality reduces the need for separate dedicated shielding components.
Solution Approach 2:
The partition walls are integrated within the holder structures, with conductive materials nested between insulating holder bodies. The partition walls are positioned within the hollow spaces of the holders, creating a compact nested arrangement that provides shielding without adding external bulk.

Implementation Method 1
an electrically conductive first partition wall that is held by the first housing so as to partition a portion of a boundary between the first holder and the second holder in a state insulated from the first contact and the second contact, and that is grounded to the first substrate

AI summary
An electrical connector pair includes a receptacle connector and a plug connector. The receptacle connector includes a first partition wall, and the plug connector includes a second partition wall. When the receptacle connector and the plug connector are fitted together, the first partition wall partitions a portion of the boundary between a third holder and a fourth holder where the second partition wall is not formed such that a first contact and a third contact cannot be seen from a second contact and a fourth contact.
