Electrical Connector Shielding Inner Shell Cross-Talk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from poor cross-talk reduction between upper and bottom contacts, leading to suboptimal signal transmission quality.
Innovation Solution
An electrical connector design featuring an insulative housing with a spacer and a shield shell that includes an inner shell and an outer shell, where the shield plate is positioned between the inner shell and the contacts, enhancing electrical contact and reducing cross-talk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the shield plate only contacts with the out shell for grounding, then the grounding function is achieved, but the cross-talk reduction between upper and bottom contacts is poor
Solution Approach 1:
The patent introduces an inner shell as an intermediary component between the shield plate and the contacts. The inner shell is positioned between the upper and bottom groups of contacts and makes contact with both the shield plate and the contacts, creating an additional shielding layer that effectively reduces electromagnetic interference and cross-talk between adjacent contact groups.
Solution Approach 2:
The patent employs a nested structure where the inner shell is placed within the outer shell, and both are positioned around the contact groups. The shield plate is received in the spacer and the inner shell is nested between the contact groups, creating multiple concentric shielding layers that enhance cross-talk reduction while maintaining signal transmission quality.
2Reliability
If a simple grounding structure is used, then the device complexity is low, but the signal transmission quality is poor
Solution Approach 1:
The patent employs a nested structure where the inner shell is placed within the outer shell, and both are positioned around the contact groups. The shield plate is received in the spacer and the inner shell is nested between the contact groups, creating multiple concentric shielding layers that enhance cross-talk reduction while maintaining signal transmission quality.
Solution Approach 2:
The inner shell serves multiple functions: it provides electromagnetic shielding between contact groups, maintains structural integrity of the connector assembly, and works in conjunction with the shield plate to create a comprehensive grounding system. This multi-functionality reduces the need for additional separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration improves signal transmission quality by effectively reducing cross-talk between the upper and bottom groups of contacts, thereby enhancing the overall performance of the electrical connector.
Implementation Method 1
The shield plate received in the spacer and abutting against the inner shell electrically. The cross-talk between the upper and bottom group of contacts and it would improve signal transmission quality of the electrical connector
