Electrical Connector Segmented Conductive Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with large connecting sections on circuit boards result in increased plating costs and lower contact reliability due to larger contact areas and reduced contact surface pressure.
Innovation Solution
The electrical connector features conductive thin sections on the edges of connecting sections with insulating areas in between, reducing the overall plating area and enhancing contact reliability by increasing contact surface pressure and allowing for greater displacement during mating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting sections have large areas to cover contact points and adjust impedance, then contact coverage is improved, but plating area increases and contact surface pressure decreases
Solution Approach 1:
The connecting section is segmented into multiple conductive regions separated by insulating areas. This segmentation allows the connecting section to maintain a smaller total plating area while providing multiple contact points that can cover displacement ranges, thereby improving contact reliability without increasing overall plating area.
Solution Approach 2:
The connecting section has different local properties: conductive regions for making contact and insulating regions for electrical isolation. This local quality differentiation allows the design to achieve both good contact coverage and proper electrical isolation with minimized plating area.
2Adaptability or versatility
If connecting sections have large areas to secure contact coverage, then displacement tolerance is improved, but contact surface pressure decreases
Solution Approach 1:
The connecting section is divided into multiple conductive regions separated by insulating areas. This segmentation allows the design to tolerate displacement across multiple contact points while maintaining concentrated contact pressure at each individual conductive region, thereby achieving both displacement tolerance and adequate contact pressure.
3Manufacturing precision
If connecting sections have large areas to adjust impedance, then impedance control is improved, but manufacturing cost increases
Solution Approach 1:
The connecting section is segmented into conductive and insulating regions, which allows for precise impedance control through the geometry and arrangement of conductive areas. This segmentation enables effective impedance management with reduced total plating area, thereby lowering manufacturing costs while maintaining manufacturing precision.
