Resilient Retention Insert for Battery Terminal Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery terminal connectors experience unwanted movement relative to the terminal post due to vibration, especially in tapered profiles, leading to potential damage from existing retention methods like ridges or dimples.
Innovation Solution
A connector with a post-engaging portion and a resiliently deformable retention insert featuring projections that pivot and deform to securely engage the terminal post, preventing movement without damaging the post.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ridges or dimples are added to the inside surface of the post-engaging portion to prevent movement, then retention is improved, but the terminal post is damaged during the lifetime of the battery
Solution Approach 1:
A retention insert is introduced as an intermediary component between the post-engaging portion and the terminal post. The insert features resiliently deformable projections that engage the terminal post without requiring permanent deformation or damage to the post itself, thus providing retention while preserving the terminal post integrity
Solution Approach 2:
The retention mechanism utilizes changes in the physical state of the retention insert material through resilient deformation. The projections are made of resiliently deformable material that can elastically deform during engagement and maintain continuous contact with the terminal post, adapting to vibrations and movement without causing damage
2Stability of the object's composition
If the clamping portion is tightened to secure the connector, then connection stability is improved, but the connector still moves or slides relative to the terminal post in vibrating environments
Solution Approach 1:
The retention insert incorporates resiliently deformable projections that can dynamically adapt to vibrations and relative movements between the connector and terminal post. Rather than relying solely on static clamping force, the dynamic resilient projections maintain continuous engagement and compensate for vibrational movements, providing reliable retention in vibrating environments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced retention and prevents damage to the terminal post, maintaining a secure connection even under harsh vibrations, while being cost-effective to manufacture.
Implementation Method 1
The insert has resiliently deformable projections which extend into the opening. With the battery terminal post inserted into the opening and the post-engaging portion moved to the secured position, the resiliently deformable projections of the insert engage and retain the battery terminal post in the opening

AI summary
A connector for terminating to a battery terminal post. The connector includes a post-engaging portion which has an opening for receiving the battery terminal post therein. The post-engaging portion is movable between an open position and a secured position. A retention insert is provided in the opening of the post-engaging portion. The insert has resiliently deformable projections which extend into the opening. With the battery terminal post inserted into the opening and the post-engaging portion moved to the secured position, the resiliently deformable projections of the insert engage and retain the battery terminal post in the opening to prevent unwanted movement of the connector relative to the battery terminal post.
