Electrical Connector Floating Housing for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face mechanical and electrical issues due to excessive elastic displacement required for contact pressure and floating, leading to contact failure and deterioration of high-speed transmission characteristics.
Innovation Solution
The electrical connector features a housing with upper and lower sections that move relative to each other in the terminal arrangement direction, with terminals held in grooves that restrict movement at narrow points, allowing for tilting without elastic deformation, and grounding terminals with sliding contact sections supported by elastic connection members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional elastic displacement is generated on terminals to secure contact pressure and enable floating, then contact reliability is improved, but mechanical strength deteriorates and high-speed transmission characteristics deteriorate
Solution Approach 1:
The invention divides the terminal into multiple functional sections: a contact section that maintains minimal elastic displacement for high-speed transmission, and a floating mechanism in the housing that absorbs positional deviations. This segmentation allows the contact-critical portion to remain rigid while the housing absorbs floating requirements, resolving the contradiction between contact reliability and mechanical strength.
Solution Approach 2:
The housing acts as an intermediary mechanism between the terminal and the mating connector. Instead of allowing the terminal itself to undergo large elastic displacements, the housing provides a floating structure that absorbs positional deviations, thereby protecting the terminal's mechanical strength and high-speed transmission characteristics while still ensuring contact reliability.
2Reliability
If additional elastic displacement is generated on terminals to secure contact pressure and enable floating, then contact reliability is improved, but high-speed transmission characteristics deteriorate
Solution Approach 1:
The terminal structure is segmented into a contact section with minimal elastic displacement for maintaining signal integrity, while the housing contains the floating mechanism. This separation ensures that high-speed signal transmission paths are not affected by large elastic displacements, while contact reliability is still achieved through the housing's floating capability.
Solution Approach 2:
The housing serves as an intermediary that decouples the floating function from the terminal's signal transmission path. By absorbing positional deviations at the housing level rather than through terminal elastic deformation, the high-speed transmission characteristics are preserved while contact reliability is maintained.
3Adaptability or versatility
If terminals are made to elastically displace for floating, then adaptability to manufacturing errors is improved, but device complexity increases
Solution Approach 1:
The housing is designed with a dynamic floating mechanism that automatically adjusts to manufacturing errors and positional deviations. This dynamic adaptation at the housing level eliminates the need for complex elastic displacement mechanisms in each terminal, thereby maintaining adaptability while reducing overall device complexity.
Solution Approach 2:
The housing's floating mechanism serves multiple functions: it absorbs manufacturing errors, enables adaptability to positional deviations, and maintains contact pressure. This multi-functionality at the housing level replaces what would otherwise require complex individual terminal mechanisms, reducing device complexity while improving adaptability.
