Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with conductive shielding members made of metal plates are costly due to expensive materials and complex assembly processes, particularly with tapping and soldering to PCBs.
Innovation Solution
A flexible conductive shielding member is used between magnetic modules, eliminating the need for taps and soldering by connecting directly through pressing to PCBs, reducing manufacturing and assembly costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal plate is used as the conductive shielding member, then the shielding effectiveness is improved, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent changes the physical state of the shielding member from rigid (metal plate) to flexible (conductive foam), allowing it to be compressed and attached without tapping or soldering operations, thereby reducing manufacturing cost and assembly complexity while maintaining shielding effectiveness
Solution Approach 2:
The patent replaces expensive metal plate material with cheaper conductive foam material that can be easily attached and removed, reducing material cost and simplifying assembly processes
2Reliability
If taps are added to the conductive shielding member for PCB connection, then the electrical connection is improved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent extracts the tapping operation from the assembly process by using a flexible shielding member that can be directly compressed onto the PCB without requiring pre-drilled holes or tapped threads, thereby eliminating a complex and time-consuming step
Solution Approach 2:
The patent replaces the mechanical tapping and threading system with a simple compression system, where the flexible shielding member is pressed onto the PCB to create both mechanical and electrical connections simultaneously

AI summary
An electrical connector includes an insulative housing defining a lower inserting port, an upper inserting port stacked thereon, and a mounting port located behind the lower and upper inserting ports. The inserting module is assembled from the mounting port to the inserting ports. The inserting module comprises a set of upper mating contacts each having a contacting portion extending into the upper inserting port, a set of lower mating contacts each having a contacting portion extending into the lower inserting port, a first magnetic module received in the mounting port and electrically connecting with the upper mating contacts, a second magnetic module received in the mounting port and electrically connecting with the lower mating contacts, and a conductive shielding member disposed between the first and second magnetic modules for shielding electromagnetic interference (EMI) therebetween. The conductive shielding member is a flexible member and connecting with the PCBs through pressing.
