Movable Terminal Beam Layout for Compact RF Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF electrical connectors with perpendicular beams at the connecting portion face challenges in size reduction and mechanical properties due to symmetric configurations, which limit their compactness and functionality.
Innovation Solution
The RF electrical connector design incorporates reversely symmetrically configured insulative bases with movable and fixed terminals, featuring beams that are partially perpendicular and partially parallel, allowing for reduced size and enhanced mechanical properties through strategically positioned notches and grooves, and an outer metallic shell for enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If both the first and second beams are substantially perpendicular to the connecting portion (symmetric configuration), then the structural symmetry is maintained, but the connector size cannot be reduced and mechanical properties are limited
Solution Approach 1:
The patent applies asymmetry by configuring the first beam to be substantially perpendicular to the connecting portion while the second beam is substantially parallel to the connecting portion. This asymmetric arrangement breaks the traditional symmetric configuration, enabling compactness and size reduction while maintaining functional performance and mechanical properties.
2Volume of moving object
If the beams are configured to reduce connector size, then compactness is improved, but mechanical properties may be compromised
Solution Approach 1:
The patent applies local quality by making each beam have different orientations tailored to their specific functional requirements. The first beam is perpendicular to optimize certain mechanical properties, while the second beam is parallel to optimize others. This localized optimization of beam orientations allows the connector to achieve compact size while maintaining or enhancing overall mechanical performance.

AI summary
An electrical connector includes: an insulative base; a fixed terminal secured to the insulative base; and a movable terminal including a securing portion fixed to the insulative base, a connecting portion, a contacting portion in touch with the fixed terminal, a first and a second beams at two opposite sides of the connecting portion, and a tail, wherein at least one of the first and second beams has a first portion substantially perpendicular to the connecting portion and a second portion substantially parallel to the connecting portion.
