Substrate-Bottom Electrical Connector for Low-Profile High-Speed Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors using printed circuit boards (PCBs) face challenges in achieving low-profile and high-speed performance, as they often require complex stamped contact structures that hinder compact design and efficient signal transmission.
Innovation Solution
The use of a substrate with conductive pads and wirings replaces traditional stamped contacts, integrating the substrate as a bottom wall of the insulative housing, enabling a low-profile and high-speed electrical connector assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional stamped contact structures are used in electrical connectors with PCBs, then the connector can achieve basic electrical connection functionality, but the structure becomes complex and the profile height increases
Solution Approach 1:
The patent merges the substrate and bottom wall into a single integrated component. The substrate is secured to the insulative housing to constitute the bottom wall, eliminating the need for separate stamped contact structures and reducing overall complexity while maintaining low profile height
Solution Approach 2:
The substrate serves multiple functions simultaneously: it provides the bottom wall structure, contains the conductive contacts for electrical connection, and integrates the wiring pathways. This multi-functionality replaces what would traditionally require multiple separate components including stamped contacts
2Reliability
If traditional stamped contact structures are used, then the connector can provide basic signal transmission, but signal transmission efficiency is reduced
Solution Approach 1:
The patent replaces the mechanical stamped contact structure with an integrated substrate-based contact system. The conductive pads on the substrate provide direct electrical connection without requiring mechanical stamped contacts, improving signal transmission efficiency by eliminating additional mechanical interfaces
3Length of moving object
If a substrate is integrated as the bottom wall to achieve low-profile design, then the connector profile is reduced, but manufacturing complexity may increase
Solution Approach 1:
The substrate and bottom wall are merged into a single integrated component. The substrate is secured to the insulative housing to constitute the bottom wall, which simplifies the overall manufacturing process by reducing the number of separate parts that need to be assembled, despite the integrated design
