Battery Terminal Connector Assembly With Biasing Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery terminal connectors often fail to provide sufficient retention force without damaging the terminal post, especially in vibrating environments, due to inadequate clamping mechanisms and excessive component complexity.
Innovation Solution
A battery terminal connector assembly featuring a biasing portion with a tapered biasing wall and engagement walls, which engages with a post engagement portion to apply a controlled, evenly distributed force for secure mechanical and electrical connection, using a fastening member to pivot the biasing portion and translate force into horizontal engagement walls for stable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ridges or dimples are added to penetrate the terminal post for additional retention, then retention force is improved, but the terminal post is damaged during the lifetime of the battery
Solution Approach 1:
A biasing portion acts as an intermediary between the clamping mechanism and the terminal post. It translates vertical clamping force into horizontal engagement force through its tapered geometry, providing retention without direct penetration or damage to the terminal post.
Solution Approach 2:
The biasing portion changes the direction and distribution of force parameters. It converts vertical clamping force into horizontal engagement force, distributing the load across engagement walls rather than concentrating it at penetration points, thereby preventing terminal post damage.
2Force
If multiple wedge blocks are used to apply clamping force, then clamping capability is improved, but the translation of force from nut torque to clamping mechanism is inadequate
Solution Approach 1:
The tapered biasing wall changes the force transmission parameter by converting vertical clamping motion into horizontal engagement force. This geometric transformation efficiently translates nut torque to clamping force without requiring complex wedge block mechanisms.
Solution Approach 2:
The invention extracts the essential force translation function from the complex multi-wedge block system and implements it through the simpler tapered biasing portion, maintaining clamping effectiveness while reducing mechanical complexity.
3Device complexity
If a simple clamping portion is used without additional retention features, then device complexity is reduced, but the terminal connector moves or slides relative to the terminal post in vibrating environments
Solution Approach 1:
The biasing portion introduces a dynamic force translation mechanism that actively engages the terminal post under vibration. The tapered geometry allows the engagement walls to maintain constant horizontal pressure on the terminal post, preventing movement during vibration while adding minimal complexity.

Function Achieved in This Case
The solution provides a secure, repeatable, and damage-free mechanical and electrical connection, effectively preventing unwanted movement of the connector assembly even under harsh vibrations, while reducing component complexity.
Implementation Method 1
A biasing wall extends about a circumference of the first terminal post receiving opening... As the biasing portion is moved from the first insertion position to the second termination position, the biasing wall engages the engagement walls and moves the engagement walls into mechanical and electrical engagement with the battery terminal post

AI summary
A battery terminal connector assembly for attaching to a terminal post of a battery includes a biasing portion and a post engagement portion. The biasing portion has a first terminal post receiving opening. A biasing wall extends about a circumference of the first terminal post receiving opening. The post engagement portion has a second terminal post receiving opening for receiving the battery terminal post therein. Engagement walls extend about a circumference of the second terminal post receiving opening. The biasing portion is movable relative to the post engagement portion between a first insertion position and a second termination position. As the biasing portion is moved from the first insertion position to the second termination position, the biasing wall engages the engagement walls and moves the engagement walls into mechanical and electrical engagement with the battery terminal post positioned in the second terminal receiving opening of the post engagement portion.
