Connector Assembly Varying Wall Thickness Impedance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems for radio-frequency cables face challenges in maintaining constant impedance and stability, especially at cable ends where connectors are mounted, leading to difficulties in achieving reliable and strong connections while ensuring signal transmission quality over large frequency ranges.
Innovation Solution
A connector assembly featuring an outer conductor sleeve with varying wall thickness regions and an insulator element, where the sleeve has a thicker attachment portion for stability and a thinner plug portion for impedance matching, along with a compression tube for secure crimping, helps maintain coaxial alignment and reduce impedance variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the outer conductor sleeve has uniform wall thickness throughout, then manufacturing is simpler, but impedance cannot be maintained constant at cable ends
Solution Approach 1:
The outer conductor sleeve is designed with different wall thicknesses in different regions: a first wall thickness in the attachment portion and a second (thinner) wall thickness in the plug portion. This local differentiation allows the attachment portion to provide mechanical stability while the plug portion maintains constant impedance for signal transmission.
2Strength
If the connector system uses a thicker wall design for stability, then connection strength is improved, but impedance matching deteriorates at the cable end
Solution Approach 1:
The connector assembly implements local quality by varying the wall thickness of the outer conductor sleeve along its length. The thicker first wall thickness region provides the necessary mechanical strength and stability in the attachment portion, while the thinner second wall thickness region in the plug portion ensures proper impedance matching for signal transmission.
3Manufacturing precision
If the connector system uses a thinner wall design for impedance matching, then signal transmission quality is improved, but mechanical stability deteriorates
Solution Approach 1:
The outer conductor sleeve is designed with different wall thicknesses in different regions: a first wall thickness in the attachment portion and a second (thinner) wall thickness in the plug portion. This local differentiation allows the attachment portion to provide mechanical stability while the plug portion maintains constant impedance for signal transmission.
4Reliability
If the connector system prioritizes strong mechanical connection, then connection reliability is improved, but impedance variations increase
Solution Approach 1:
The connector assembly implements local quality by varying the wall thickness of the outer conductor sleeve along its length. The thicker first wall thickness region provides the necessary mechanical strength and stability in the attachment portion, while the thinner second wall thickness region in the plug portion ensures proper impedance matching for signal transmission.
