High-Frequency Plug Connector Guide Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency connectors are prone to misalignment and damage during the joining process due to the lack of precise guidance, which can lead to improper alignment and subsequent damage to the outer conductor contacts.
Innovation Solution
Incorporating additional guide surfaces on both connectors to ensure precise alignment and orientation, with the first guide surface on the first connector and the second guide surface on the second connector, spaced axially from their respective outer conductor contact sections, to prevent misalignment and protect the outer conductor contacts during the mating process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If outer conductor contacts are designed as resilient contact elements, then electrical contact reliability is improved, but they are easily damaged during joining process due to misalignment
Solution Approach 1:
The guide surfaces are positioned to engage and establish precise alignment between connectors before the outer conductor contacts make contact. This preliminary alignment action prevents misalignment damage to the resilient outer conductor contacts while maintaining their electrical reliability
Solution Approach 2:
The guide surfaces act as an intermediary mechanism that mediates the joining process. They first establish the correct spatial relationship between connectors, allowing the outer conductor contacts to engage safely without direct misalignment forces
2Manufacturing precision
If guide surfaces are positioned close to outer conductor contact sections, then alignment guidance is improved, but risk of misalignment damage increases
Solution Approach 1:
The guide surfaces are positioned axially before the outer conductor contact sections to perform alignment guidance in advance. This spacing ensures that alignment is established before contact engagement, preventing misalignment damage while maintaining precision
3Device complexity
If outer conductor contact section is integrated with outer conductor part, then structural simplicity is improved, but material property optimization is limited
Solution Approach 1:
The outer conductor contact section is segmented as a separate component that can be pressed into the outer conductor part. This segmentation allows independent material selection and optimization for each component while maintaining a relatively simple overall structure through the press-fit connection
