Low-Profile Electrical Connection Unit With Planar Bus Bar Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to further reduce the height of electrical connection units while maintaining their functionality and efficiency.
Innovation Solution
The electrical connection unit is designed with a first and second subunit, each containing electronic components and bus bars, integrated by a metal plate, allowing for a compact arrangement of routing boards on the same plane and reducing overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bus bars are arranged in a standing posture on the housing, then electrical connection functionality is achieved, but the height of the electrical connection unit increases
Solution Approach 1:
The bus bars are changed from a vertical standing posture to a horizontal arrangement on the same plane. The routing boards are disposed horizontally on the housing, with bus bars extending in the horizontal direction, transforming the spatial dimension from vertical to horizontal to reduce height while maintaining electrical connection functionality
Solution Approach 2:
Multiple routing boards containing bus bars are integrated and fixed to the same housing structure. The first and second routing boards are disposed on the housing and electrically connected, merging multiple electrical connection functions into a single integrated assembly that reduces overall height

AI summary
An electrical connection unit includes a first subunit, a second subunit, and a metal plate. The first subunit includes a plurality of first electronic components, a plurality of first bus bars, and a first base member. The plurality of first bus bars include portions disposed on the same plane, and are electrically connected to the plurality of first electronic components. The first base member includes a plate-shaped first flat surface portion that holds the plurality of first bus bars. The second subunit includes a plurality of second electronic components, a plurality of second bus bars, and a second base member. The second base member includes a plate-shaped second flat surface portion that holds the plurality of second bus bars. The metal plate has the first subunit and the second subunit fixed thereto, and integrally holds the first subunit and the second subunit.
