Shielded Connector Assembly for Retention and Airflow Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies lack sufficient retention force and resistance to insertion force, and their heat dissipation mechanisms are inefficient, particularly in the context of pluggable modules.
Innovation Solution
The connector assembly incorporates a guiding shield cage with an outer shell and supporting seats, featuring supporting seat fixing portions and partitioning components that enhance retention force and resistance to insertion, while promoting heat dissipation through air flow passageways and holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the outer shell is fixed to the PCB using only elastic pins through through holes, then the structure is simple, but the retention force and resistance to insertion force are insufficient
Solution Approach 1:
The fixing structure is segmented into multiple independent supporting seats, each with engaging portions that connect to the outer shell and supporting portions that fix to the PCB. This segmentation allows the fixing function to be distributed across multiple locations, increasing overall retention force without requiring a single complex fixing mechanism.
Solution Approach 2:
The supporting seats extend in the height direction (vertical dimension) beyond the outer shell, providing additional fixing points on the PCB. This dimensional extension allows the fixing structure to engage with the PCB at multiple height levels, significantly improving retention force and resistance to insertion force.
2Temperature
If heat dissipating holes are only provided in the wall portions of the outer shell, then the structure is simple, but the heat dissipation efficiency is insufficient
Solution Approach 1:
The heat dissipation structure is segmented into multiple pathways: heat dissipating holes in the wall portions, additional heat dissipating holes in the supporting seats, and air flow passageways connecting these holes. This segmentation creates multiple parallel heat dissipation channels, significantly improving heat dissipation efficiency.
Solution Approach 2:
Heat dissipation is extended from the horizontal wall portions to the vertical supporting seats. The supporting seats provide additional heat dissipation surfaces in the height direction, and air flow passageways enable three-dimensional air circulation patterns, improving heat dissipation efficiency without simply increasing the number of holes in a single plane.
3Stability of the object's composition
If the partitioning piece assembly has a closed state at the front end, then structural integrity is improved, but heat dissipating air flow cannot enter between the partitioning pieces
Solution Approach 1:
The partitioning piece assembly is segmented to include both closed portions (for structural integrity) and open portions with gaps (for heat dissipation). The supporting seats are also segmented with through holes that provide additional heat dissipation pathways independent of the partitioning piece gaps, allowing the structure to maintain both integrity and thermal performance.
