Multi-Path Electrical Connector for High-Frequency Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors have poor high-frequency characteristics due to a single connecting path, rely on limited elastic force for contact reliability, are prone to short circuits and deformation, and can experience connection loss due to lateral movement and twisting forces.
Innovation Solution
A multi-path electrical connector design featuring a base plate, first and second connecting arms, and a contact arm with additional parallel and obliquely extending arms, configured as C, U, or V shapes, and side plates to distribute elastic force and prevent twisting, enhancing high-frequency performance and contact reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elastic arm is used to form the connecting path, then the structure is simple, but the high-frequency characteristics are poor
Solution Approach 1:
The single elastic arm is segmented into multiple connecting arms (first connecting arm, second connecting arm, third connecting arm) that form separate connecting paths. This segmentation allows high-frequency current to distribute across multiple paths, improving high-frequency characteristics while maintaining reasonable structural complexity through the use of elastic metal sheet material.
2Device complexity
If only elastic force is used to ensure contact reliability, then the structure is simple, but the contact reliability is decreased and the duration is short
Solution Approach 1:
The elastic force generation is segmented across multiple arms (first connecting arm, second connecting arm, third connecting arm), each contributing to the overall contact reliability. This distribution of elastic force generation improves durability and contact reliability while maintaining structural simplicity through the integrated elastic metal sheet design.
3Force
If the elastic arm is pressed downwards excessively, then the contact force is sufficient, but the elastic arm may contact the circuit board causing short circuit or deform permanently
Solution Approach 1:
The pressing force is segmented and distributed across multiple arms (first connecting arm, second connecting arm, third connecting arm), which share the load and prevent any single arm from being pressed excessively. This distribution prevents the elastic arms from contacting the circuit board or undergoing permanent deformation while maintaining sufficient contact force.
Solution Approach 2:
The connecting arms are configured in different spatial dimensions and orientations (first connecting arm extending upward, second connecting arm extending downward to contact base plate, third connecting arm parallel to base plate). This multi-dimensional arrangement distributes the mechanical stress and prevents excessive compression in any single direction, avoiding short circuits and permanent deformation.
4Ease of operation
If the elastic arm is allowed to move laterally when depressed, then the movement freedom is high, but twisting force is generated and connection is destroyed
Solution Approach 1:
The connecting arms are arranged in specific spatial configurations with the first connecting arm extending upward, the second connecting arm extending downward to contact the base plate, and the third connecting arm parallel to the base plate. This multi-dimensional arrangement guides movement along predetermined paths, preventing lateral displacement and twisting forces that would destroy the connection between the body and circuit board.

Function Achieved in This Case
The multi-path design improves high-frequency characteristics by allowing current to flow through the path with the smallest impedance, increases contact reliability through distributed elastic force, and prevents connection loss by guiding arm movement, thus enhancing durability and reducing stress.
