Battery Pack Connector Retainer for Detection Wire Separation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face challenges in securely connecting detection wires for transmitting state information to circuit units, leading to potential separation issues and complicating detachable fastening operations, which affects the workability and reliability of the battery pack and connector assembly.
Innovation Solution
A battery pack design featuring a connector with a rim edge member and an accommodation member, coupled with a retainer that extends across the detection wire, providing a secure and easy-to-use connection mechanism to prevent separation and facilitate detachable fastening with a circuit unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is used to connect detection wire and circuit unit, then electrical connection is achieved, but separation of detection wire may occur
Solution Approach 1:
A retainer is introduced as an intermediary component between the connector and detection wire. The retainer includes a body that receives the detection wire and locking protrusions that engage with corresponding grooves on the connector, creating a three-component assembly (connector-retainer-detection wire) that prevents direct connection issues while ensuring reliable electrical connection.
Solution Approach 2:
The connection system is divided into separate functional components: the connector for electrical connection, the retainer for mechanical retention, and the detection wire for signal transmission. This segmentation allows each component to be optimized for its specific function while working together as an integrated system.
2Ease of operation
If detachable fastening is implemented, then ease of operation is improved, but complexity of connection mechanism increases
Solution Approach 1:
The connector incorporates a movable pressing portion that can transition between engaged and disengaged states. When pressed, the pressing portion moves to release the locking protrusions from the grooves, enabling easy detachment. This dynamic mechanism provides simple operation while maintaining a relatively compact structure.
Solution Approach 2:
The pressing portion is designed to be directly operable by user force without requiring additional tools or complex actuation mechanisms. The structural design allows the connector to self-release when the pressing portion is actuated, eliminating the need for separate release mechanisms.
