Connector Ground Stabilization Member for PIMD Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication system connectors lack effective ground stabilization, which can affect the performance of filters and lead to poor communication characteristics such as increased passive intermodulation distortion (PIMD).
Innovation Solution
A connector with a ground stabilization member coupled to the connector body and communication component, featuring a fixing portion, an insertion portion with elastic slots, and a ground contact portion that securely contacts the inner wall of the communication component's insertion hole, providing stable grounding and improved elastic strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector without ground stabilization is used, then the device complexity is reduced, but the communication characteristics deteriorate due to poor grounding and increased PIMD
Solution Approach 1:
The ground stabilization member is divided into distinct functional portions: a fixing portion for attachment to the connector body, an insertion portion for insertion into the communication component, and a ground contact portion for establishing electrical contact with the inner wall. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
The ground stabilization member incorporates slots at specific locations to provide localized elasticity. These slots are positioned to allow the ground contact portion to flex and maintain reliable contact with the inner wall, while other portions maintain sufficient rigidity for structural support and electrical conductivity.
2Reliability
If the ground contact portion is made rigid to ensure stable contact, then the grounding function is improved, but the ability to adapt to manufacturing tolerances deteriorates
Solution Approach 1:
The ground stabilization member utilizes elastic deformation as a design parameter, allowing the ground contact portion to change its physical state from rigid to flexible. The slots are strategically positioned and sized to control the degree of elasticity, enabling the member to flex within acceptable limits while maintaining reliable electrical contact and adapting to manufacturing variations.
3Adaptability or versatility
If multiple slots are added to the insertion portion to provide elasticity, then the adaptability is improved, but the structural strength deteriorates
Solution Approach 1:
The slots are positioned specifically in regions where localized flexibility is needed to accommodate manufacturing tolerances and maintain contact pressure, while avoiding critical load-bearing areas. This selective placement of slots provides the necessary elasticity for adaptation without compromising the overall structural integrity of the ground stabilization member.
