Connector Design Without Partition Ribs for Resonance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing input/output connectors with insulation partition ribs between connection portions are limited in width and spacing, which restricts their performance and hampers the suppression of resonance.
Innovation Solution
A connector design without insulation partition ribs between adjacent connection portions, utilizing air gaps to increase design space and adjust resonance amplitude, thereby improving performance by optimizing contact width and pitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulation partition ribs are disposed between connection portions of adjacent contacts, then short circuit between connection portions is avoided, but the width of contacts and spacing between adjacent contacts is limited
Solution Approach 1:
The patent removes the insulation partition ribs from between connection portions, extracting the element that was limiting contact width and spacing. Short circuit prevention is achieved through alternative means (insulation coating on connection portions or design of air gaps), allowing the connection portions to be positioned closer together or made wider without the constraint of physical partition ribs.
Solution Approach 2:
The patent changes the insulation approach from using physical partition ribs to using insulation coating or air gap design. This parameter change in the insulation method enables greater flexibility in contact width and spacing while still preventing short circuits between adjacent connection portions.
2Reliability
If insulation partition ribs are used to separate connection portions, then electrical isolation is achieved, but resonance suppression performance is hampered
Solution Approach 1:
The patent extracts the insulation partition ribs that were causing resonance issues. By removing these rigid structures and replacing them with insulation coating or controlled air gaps, the source of resonance is eliminated while electrical isolation is maintained through the alternative insulation methods.
Solution Approach 2:
The patent converts the potential harm of air gaps (which could cause short circuits) into a beneficial feature by controlling the air gap dimensions and adding insulation coating. The air gaps that would normally be problematic are now used to reduce resonance while still preventing short circuits through proper insulation design.
3Object-generated harmful factors
If contact width and spacing are increased to suppress resonance, then resonance suppression improves, but the need for insulation partition ribs increases
Solution Approach 1:
Instead of using insulation partition ribs to prevent short circuits and then dealing with resonance as a secondary issue, the patent inverts the approach by first addressing resonance suppression through increased contact width and spacing, then solving the short circuit prevention issue through insulation coating or air gap design. This reversal of problem-solving sequence simplifies the overall structure.
Solution Approach 2:
The patent changes the insulation implementation from rigid partition ribs to flexible insulation coating or controlled air gaps. This parameter change in the insulation approach allows for greater contact width and spacing to suppress resonance while maintaining electrical isolation without increasing structural complexity.

AI summary
A connector comprises an insulation body and a row of first contacts arranged on the insulation body at a first pitch. Each of the first contacts includes a first solder foot, a first fixation portion, and a first connection portion between the first solder foot and the first fixation portion. No insulation partition rib is disposed between the first connection portions of any two adjacent first contacts.
