Solution Overview

Problem

Conventional Faraday and Gaussian cages struggle to effectively transmit high-frequency signals through metal containers with strong energy fields while maintaining signal integrity, as they fail to isolate energy effectively between signals or pairs within the enclosure.

Innovation Solution

A connector apparatus using a single or paired set of wire cores terminated to a connector contact, configured within a Gaussian or Faraday chamber made of EMI absorption metal, with a commonly grounded geometry to isolate field energies between signals, similar to semi-rigid wires, employing materials like Mu Metal and Nickel-Cobalt to absorb field energy and reduce cross-talk.

1Object-affected harmful factors

If conventional Faraday and Gaussian cages are used to block electromagnetic fields, then EMI shielding is achieved, but signal integrity deteriorates due to inability to isolate energy between signals within the enclosure

Engineering Contradiction:
ImproveEMI shieldingVSAvoidsignal integrity
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The connector is divided into multiple isolated Gaussian chambers, each enclosing individual signal pairs. This segmentation isolates electromagnetic energy between different signals while maintaining overall EMI shielding, resolving the contradiction between blocking external interference and preventing internal signal interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the connector are assigned different functions: some chambers enclose signal pairs for data transmission, while others contain ground signals for reference potential. This local differentiation optimizes both EMI shielding and signal integrity by providing appropriate electromagnetic environment for each signal type.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If ground signals are placed between signal pairs to reduce energy, then EMI shielding improves, but device complexity increases due to additional ground signal requirements

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple signal pairs and ground signals are merged into a single integrated Gaussian chamber connector structure. The chambers are arranged to provide both shielding and signal isolation without requiring separate components, reducing overall device complexity while maintaining energy field control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The Gaussian chamber structure serves multiple functions simultaneously: it provides EMI shielding, isolates signal pairs, contains ground references, and maintains impedance control. This multi-functionality eliminates the need for separate components for each function, reducing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 1:

The connector uses composite construction with outer EMI-shielding materials and inner Mu Metal/Nickel-Cobalt chambers for field absorption. This layered composite approach optimizes signal integrity while allowing each material to be applied through specialized processes, balancing manufacturing complexity with performance.

AI summary

A connector system, method and apparatus for an EMI enclosure such as a Gauss/Faraday cage or chamber. The connector system, method and/or apparatus includes one or more individual conductors located within the EMI enclosure to eliminate EMI/E&H field effects with respect to applications such as a small form factor cable applications, high density cable applications, and a high speed (e.g., greater than 1 Gbps) multiconductor copper-based cable applications. This approach therefore isolates individual or multiple cable signals (e.g., single conductors) within individual Gaussian/Faraday cages to eliminate EMI/E&H field effects for small form factor, high density, high speed (e.g., >1 Gbps) multiconductor copper based cable applications.
