Battery Connection Assembly With Protruding Insulation Against Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrical connection sheets in battery assemblies, when placed in a metal housing, can release high voltage and cause electric leakage due to direct contact with surrounding conductors, and are prone to instability from external impacts.
Innovation Solution
An electrical connection assembly is designed with an insulating member that protrudes beyond the connection member, preventing direct contact with the housing and absorbing external forces, comprising insulating pieces that enhance insulation and buffer capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical connection member is placed in a metal housing, then the electrical connection can be established, but the electrical connection member may directly contact the housing causing electric leakage
Solution Approach 1:
An insulating member is introduced as an intermediary between the electrical connection member and the metal housing. The insulating member includes an insulating shell that wraps around the electrical connection member and protrudes from its surface, creating physical separation and preventing direct contact with the conductive housing, thereby eliminating the electric leakage pathway while maintaining electrical connection functionality
2Device complexity
If the electrical connection member is exposed, then the connection structure is simple, but the connection member is vulnerable to external impacts causing instability
Solution Approach 1:
The insulating member is designed to protrude from the electrical connection member in advance, creating a protective buffer layer before external impacts can reach the connection member. This protruding insulating structure absorbs and distributes external forces, protecting the electrical connection member from direct impact and maintaining connection stability
