Micro RF Connector Resilient Terminal Uniform Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro radio-frequency connectors experience unstable signal transmission and reduced serviceable life due to non-uniform force application and potential metal fatigue in the resilient terminal, resulting from cantilever beam structures that apply uneven pressure.
Innovation Solution
The design incorporates a resilient terminal with an arc-shaped structure providing multiple evenly distributed fulcrums, ensuring uniform force application and reducing deformation through a dome structure, which stabilizes contact and extends service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If cantilever beam structures are used for resilient arms, then the resilient terminal can provide contact force, but the force applied is non-uniform causing unstable contact
Solution Approach 1:
The resilient terminal is divided into multiple resilient arms (first resilient arm, second resilient arm, third resilient arm) that are independently supported by the base. Each arm provides contact force through its own support point, segmenting the force application to achieve more uniform distribution across the contact interface with the external connector.
Solution Approach 2:
Each resilient arm has different structural characteristics optimized for its specific position and function. The first resilient arm has a first support point, the second resilient arm has a second support point, and the third resilient arm has a third support point on the base. This local differentiation allows each arm to apply force optimally at its designated location, achieving uniform overall force distribution.

The resilient terminal is divided into multiple resilient arms (first resilient arm, second resilient arm, third resilient arm) that are independently supported by the base. Each arm provides contact force through its own support point, segmenting the force application to achieve more uniform distribution across the contact interface with the external connector.

Implementation Method 1
The resilient terminal includes a fixing section, two resilient arms and a first contacting section. Each of the resilient arms is an arc structure and an arc region of the resilient arm faces downwardly... An end of the resilient arm is connected to the fixing section and contacts against the lower inner wall, the other end of the resilient arm is a free end

AI summary
A micro radio-frequency connector includes an isolated body, a resilient terminal and an external terminal. The isolated body includes an accommodating slot and an inserting hole connected to the accommodating slot. The accommodating slot includes an upper inner wall and a lower inner wall opposite to each other. The resilient terminal is disposed inside the accommodating slot, and includes a fixing section, two resilient arms and a first contacting section. The fixing section is fixed to the accommodating slot. An end of the resilient arm is connected to the fixing section and contacts against the lower inner wall, the other end of the resilient arm is a free end to be separated from the lower inner wall while an external force is not applied to the first contacting section and further to contact against the lower inner wall while the external force is applied to the first contacting section.
