Exposed Bus Bar Structure for Heat-Dissipating Electrical Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection units face challenges in improving heat dissipation properties.
Innovation Solution
Incorporating a bus bar that is electrically connected to electronic components via connection components, with the bus bar having a plate portion accommodated in an accommodation portion of a base member and an extending portion exposed outside, enhancing heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a bus bar is accommodated entirely within the base member, then the structural integrity is maintained, but the heat dissipation property deteriorates
Solution Approach 1:
The bus bar is configured to extend in two dimensions: horizontally within the base member accommodation portion and vertically outward from the base member surface. This L-shaped configuration allows the bus bar to serve dual purposes - maintaining structural integrity within the base member while providing extended heat dissipation surface area outside the base member.
2Temperature
If the bus bar extends outside the base member, then the heat dissipation area increases, but the device complexity increases
Solution Approach 1:
The bus bar serves multiple functions simultaneously: it provides electrical connection between components, maintains structural support within the base member, and acts as a heat dissipation element extending outside the base member. This multi-functionality reduces the need for separate dedicated heat dissipation components, thereby limiting the increase in device complexity.
3Temperature
If the plate portion of the bus bar is made larger to improve heat dissipation, then the heat transfer efficiency improves, but the accommodation space within the base member is reduced
Solution Approach 1:
The bus bar is segmented into two distinct functional portions: a plate portion accommodated within the base member that provides electrical connection and structural support, and an extending portion that protrudes outside the base member that provides heat dissipation surface area. This segmentation allows optimization of each portion for its specific function without compromising the other.

AI summary
An electrical connection unit includes a first electronic component, a base member, a first connection component, and a bus bar. The base member includes a flat surface portion. The flat surface portion has a first surface facing the first electronic component and a second surface located opposite the first surface. The flat surface portion includes an accommodation portion recessed or penetrating the flat surface portion in a first direction (thickness direction). The bus bar includes a plate portion accommodated in the accommodation portion and extending along the flat surface portion. The plate portion includes a first connection portion that overlaps the first connection component, and an extending portion extending from the first connection portion in a second direction intersecting the first direction. At least part of the extending portion is exposed to an outside of the base member on the first surface side.
