Terminal Block Heat Transfer Structure for Bus Bar Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus bar connection structures require additional cooling structures for bus bars other than the connection portion, complicating the peripheral structure.
Innovation Solution
A terminal block design that integrates a heat transfer sheet and a protruding portion to press another bus bar against it, simplifying the peripheral structure by integrating cooling and support functions into a single member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate cooling structure is added for another bus bar, then cooling coverage is improved, but device complexity increases
Solution Approach 1:
The patent merges the cooling function for another bus bar into the existing terminal block by adding a protruding portion. This integrates what would have been a separate cooling structure into the terminal block itself, thereby expanding cooling coverage without proportionally increasing device complexity.
Solution Approach 2:
The terminal block is designed to perform multiple functions: it supports the connection portion between bus bars, provides cooling at the connection portion, and additionally cools another bus bar through the protruding portion. This multi-functionality reduces the need for separate dedicated cooling structures.
2Device complexity
If a pressing member is integrated into the terminal block, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The pressing member is merged with the terminal block body as an integrated protruding portion. This eliminates the need for separate pressing members and reduces assembly steps, though it requires the terminal block to be manufactured as a single integrated component with precise dimensional tolerances.

Function Achieved in This Case
Simplifies the peripheral structure of bus bar connections by allowing integrated cooling and support, reducing the number of components and enhancing cooling efficiency.
Implementation Method 1
a heat transfer sheet, being an insulator, to be interposed between the heat transfer portion and the base
Implementation Method 2
a part of another bus bar can be pressed against the heat transfer sheet and cooled by the protruding portion

AI summary
A terminal block supports a bus bar connection portion as a connection portion between a plurality of bus bars. The heat transfer portion is attached to the terminal block body so as to be exposed on both sides in a Z direction from the terminal block body. The heat transfer portion allows the bus bar connection portion to be fastened to an end portion thereof on the Z+side. The protruding portion protrudes from the terminal block body in an X direction and can be fastened to the base. A heat transfer sheet being an insulator can be interposed between the heat transfer portion and the base. A bus bar other than the plurality of bus bars and a heat transfer sheet being an insulator can be interposed between the protruding portion and the base, in this order from the Z+ side.
