Floating Coaxial Connector Assembly for Offset Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors fail to provide adequate floating connection performance, particularly in meeting offset mating requirements due to limited swing range of conductive terminals caused by soldering tails on printed circuit boards, which restricts their ability to handle various angles and vibrations effectively.
Innovation Solution
A coaxial connector assembly comprising a floating terminal module with an elastic connecting portion and a fixed terminal module with a soldering tail, where the floating module uses the connecting portion as a fulcrum to deflect radially relative to the fixed module, allowing for offset mating and stable signal transmission across varying angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering tails are used to mount conductive terminals on the printed circuit board, then the connector can be firmly fixed, but the swing range of the conductive terminals is limited and cannot meet offset mating requirements
Solution Approach 1:
The connector is divided into two separate modules: a fixed terminal module that remains stationary and a floating terminal module that can move independently. This segmentation allows the fixed module to maintain firm fixation while the floating module provides the necessary swing range for offset mating, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The floating terminal module is designed with dynamic movement capability, allowing it to swing and adjust its position relative to the fixed terminal module. This dynamic design enables the connector to adapt to various mating angles and offset positions while maintaining reliable electrical connection, thus providing both firm fixation and adequate swing range.
2Stability of the object's composition
If the conductive terminal is rigidly fixed to the printed circuit board, then structural stability is maintained, but it cannot accommodate vibrations and angle variations
Solution Approach 1:
By separating the connector into fixed and floating modules, the structure maintains overall stability through the fixed module while the floating module independently absorbs vibrations and angle variations, protecting the rigid connection between the connector and printed circuit board from harmful mechanical stresses.
Solution Approach 2:
The floating terminal module acts as a cushioning element that anticipates and absorbs vibrations and mechanical stresses before they can reach the rigid fixed terminal module and printed circuit board connection, thereby protecting the overall structure from harmful factors while maintaining structural stability.
3Manufacturing precision
If the connector is designed for precise alignment, then signal transmission quality is improved, but it becomes sensitive to offset mating and angle variations
Solution Approach 1:
The floating terminal module introduces dynamic adjustment capability that compensates for alignment deviations caused by offset mating or angle variations. This allows the connector to maintain precise signal transmission quality even when subjected to manufacturing tolerances or installation variations, effectively decoupling alignment precision from sensitivity to offset mating.
4Ease of manufacture
If the connector structure is simplified, then manufacturing cost is reduced, but floating connection performance and swing range are compromised
Solution Approach 1:
The connector is segmented into two modular units that can be manufactured separately using standard processes, then assembled together. This segmentation maintains manufacturing simplicity while enabling the floating module to provide the necessary swing range and connection performance, as each module can be produced independently with conventional techniques.
