Coaxial Connector Shell Layout for Radial Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors face challenges in determining the radial position of the tip part of the shell with respect to the receptacle, making it difficult to achieve a satisfactory connection.
Innovation Solution
A connector design featuring an outer conductor divided into two regions in the circumferential direction, with a fixed contact point portion in one region and a resilient contact point portion in the other, facilitating position determination and ensuring a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tip part of the shell resiliently contacts the inner surface of the receptacle over an entire periphery, then the connection reliability is improved, but the ability to determine radial position deteriorates
Solution Approach 1:
The contact surface of the shell tip is segmented into multiple discrete contact points rather than a continuous peripheral surface. This segmentation allows specific points to provide stable contact for reliability while leaving gaps that enable radial position determination through position sensing mechanisms.
Solution Approach 2:
Different regions of the shell tip are given different properties: specific localized contact points provide stable mechanical contact for reliability, while the spaces between these points allow for position detection. This local differentiation resolves the contradiction by assigning different functions to different locations on the same component.
2Ease of operation
If the outer conductor is divided into fixed and resilient contact point portions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The outer conductor is segmented into distinct fixed contact point portions and resilient contact point portions. This segmentation enables the fixed portions to provide stable reference points for position determination while the resilient portions accommodate manufacturing tolerances and assembly variations, improving ease of operation despite increased structural complexity.
Solution Approach 2:
The contact point structure incorporates both static (fixed) and dynamic (resilient) elements. The fixed contact points provide stable reference for positioning operations, while the resilient contact points dynamically adapt to accommodate variations in assembly, making the connector easier to operate despite the more complex contact point structure.
