Clamping Acquisition Terminal for Vibration-Stable Busbar Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power battery acquisition terminals in automobiles are prone to loosening during vibrations, leading to increased internal resistance and acquisition failures due to the use of flag-shaped connectors, which require frequent reconnection, compromising data stability and efficiency.
Innovation Solution
A connecting terminal for acquisition wire harness with an intermediate connecting portion, wire harness connecting portion, and busbar connecting portion, featuring a clamping mechanism that secures the busbar connecting portion to an accommodating portion on the busbar, enhancing stability and reducing loosening during vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flag-shaped connector is used for connection between wire harness and busbar, then the connection structure is simple and easy to manufacture, but the connector is easily loosened during vibration, causing increased contact internal resistance and acquisition abnormalities
Solution Approach 1:
The connecting terminal is divided into multiple functional portions: a busbar connecting portion for clamping to the busbar, a wire harness connecting portion for pressing the wire harness, and an intermediate connecting portion that fixedly connects both. This segmentation allows each portion to be optimized for its specific function while maintaining overall connection stability during vibration.
2Ease of operation
If the flag-shaped connector is frequently pulled out and inserted again, then the connection can be re-established, but too many times of pulling out and inserting cause looseness, leading to acquisition failure
Solution Approach 1:
The connecting terminal is pre-assembled with the wire harness connecting portion and busbar connecting portion already fixedly connected through the intermediate connecting portion. This preliminary assembly ensures proper alignment and connection strength before installation, eliminating the need for frequent reconnection operations and preventing loosening over time.
3Reliability
If a clamping mechanism is used to secure the busbar connecting portion to the busbar, then the connection stability during vibration is improved, but the device complexity increases
Solution Approach 1:
The clamping mechanism is integrated into the busbar connecting portion of the connecting terminal itself, merging the clamping function with the connection structure. This eliminates the need for separate clamping devices or additional components, maintaining connection stability during vibration without significantly increasing device complexity.
