Floating PCB Connector Module for Precise Multi-Connector Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors on circuit boards and pluggable devices face challenges in improving transmission speed due to the need for precise alignment, which is not adequately addressed by existing methods, and result in increased height, failing to meet thinning requirements.
Innovation Solution
A connection module design featuring a hard circuit board with floating plates and connectors, separated by disconnecting notches, allowing them to float in any direction, eliminating the need for additional guide frames and enabling precise alignment without increasing overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flexible circuit board is used to allow connectors to float for precise alignment, then alignment precision is improved, but overall height increases due to the need for an additional guide frame
Solution Approach 1:
The circuit board is segmented by disconnecting notches that separate it into multiple floating plates, allowing each plate with its connector to move independently for precise alignment while eliminating the need for a guide frame structure
Solution Approach 2:
The circuit board transitions from a rigid structure to a dynamic structure with floating plates that can move relative to each other, enabling automatic alignment during the plugging process while maintaining a compact overall height
2Speed
If multiple connectors are provided on pluggable device and circuit board to improve transmission speed, then transmission speed is improved, but alignment difficulty increases
Solution Approach 1:
Multiple floating plates with connectors can move independently during the plugging process, allowing automatic alignment compensation that becomes more effective as the number of connectors increases, thereby supporting higher transmission speeds without proportionally increasing alignment difficulty
3Manufacturing precision
If connectors are made floatable to enable precise alignment, then alignment precision is improved, but device complexity increases due to additional guide structures
Solution Approach 1:
The circuit board is divided into floating plates by disconnecting notches, using the board's own segmented structure to provide the floating function rather than adding separate guide frames or support structures, thereby reducing overall device complexity
Solution Approach 2:
The disconnecting notches serve multiple functions: they create the floating plates for alignment precision, act as the mechanism enabling the floating motion, and eliminate the need for separate guide structures, thereby reducing device complexity while maintaining alignment precision
