Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-speed I/O connectors face challenges in achieving effective heat dissipation while maintaining a compact size, as traditional heat dissipation members are often disposed outside the metal shell, increasing the connector's dimensions.
Innovation Solution
An electrical connector design with a heat dissipation metal plate embedded within the housing, where the plate connects with the shielding shell through contact ears to facilitate heat transfer and dissipation, ensuring efficient heat management without enlarging the connector's footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation member is disposed outside the metal shell, then the heat dissipation function is improved, but the dimension of the electrical connector increases
Solution Approach 1:
The heat dissipation metal plate is embedded within the insulator base, which is itself housed inside the metal shell. This nested arrangement allows the heat dissipation component to be contained within the existing connector boundaries, maintaining compact dimensions while preserving heat dissipation functionality through thermal contact between the plate, shielding shell, and metal shell
Solution Approach 2:
The heat dissipation metal plate is integrated with the insulator base as a single embedded structure, combining the insulating function of the base with the thermal management function of the metal plate. This merging eliminates the need for separate external heat dissipation components, thereby maintaining compact connector dimensions
2Length of stationary object
If a heat dissipation member is embedded in the housing, then the dimension of the electrical connector is reduced, but the heat dissipation efficiency may be compromised
Solution Approach 1:
The shielding shell acts as an intermediary thermal conductor between the embedded heat dissipation metal plate and the external metal shell. Heat transfers from the plate through the shielding shell to the metal shell, which then dissipates heat to the environment. This intermediary pathway ensures efficient heat transfer while maintaining the embedded compact structure
Solution Approach 2:
The heat dissipation metal plate is strategically embedded in specific regions of the insulator base where thermal contact with the shielding shell is optimized. This localized placement ensures efficient heat transfer pathways are established without requiring the entire housing structure to be modified, maintaining both compact dimensions and heat dissipation efficiency
