Plug Socket Connector Heat Dissipation and Contact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug and socket connectors suffer from ineffective heat dissipation due to the absence of gas convection channels, leading to continuous heat circulation and increased resistance between terminals, which impairs performance and generates excessive heat at the joint surface.
Innovation Solution
The design incorporates hook holes for terminal stability, elastic clips for enhanced contact points, heat sinkers for improved heat dissipation, and heat dissipation holes and channels on the insulating frame to facilitate convection and prevent heat buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface contact structure is adopted for mutually butted terminals, then connection simplicity is improved, but contact resistance increases and heat generation becomes serious
Solution Approach 1:
The terminal contact surface is segmented into multiple convex portions and corresponding concave portions, transforming a single large contact area into multiple smaller contact points. This segmentation increases the effective contact area and improves heat dissipation while maintaining connection simplicity.
Solution Approach 2:
The contact surfaces are designed with localized convex and concave features at specific positions, creating optimized contact zones with improved electrical and thermal properties while keeping the overall structure simple.
2Ease of manufacture
If conventional insulating frame structure is used, then manufacturing simplicity is improved, but heat dissipation capability deteriorates due to lack of convection channels
Solution Approach 1:
The insulating frame is designed with through-holes creating a porous structure that enables gas convection channels. This allows heat to be carried away by convective air flow while maintaining manufacturing simplicity through standard molding techniques.
Solution Approach 2:
Gas convection channels are introduced into the insulating frame structure, utilizing fluid (air) flow to enhance heat dissipation. The through-holes create pathways for air circulation, enabling pneumatic/convective heat removal without complicating the manufacturing process.
