Flexible Cable Tie Structure for Stable High-Voltage Connector Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face challenges with connection reliability due to size tolerance issues with hard plastic protective covers, leading to limit failures, shaking, and increased manufacturing costs, especially with high-voltage connectors.
Innovation Solution
A flexible cable tie is used to secure high-voltage connectors, allowing for adjustable tightness and preventing loosening, which adapts to various sizes without cracking, thus enhancing connection stability and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard plastic protective covers are used to secure connectors, then protective coverage is provided, but size tolerance issues lead to limit failures and shaking
Solution Approach 1:
The patent replaces rigid hard plastic protective covers with a flexible cable tie that can adapt to different connector sizes. The flexible material allows the cable tie to wrap around connectors of varying dimensions while maintaining secure fastening, eliminating the size tolerance issues that cause limit failures and shaking with rigid covers.
Solution Approach 2:
The cable tie changes its physical parameters (length, wrapping tightness, configuration) to adapt to different connector sizes. By adjusting these parameters, the same flexible cable tie can securely fasten connectors across a range of sizes, providing both reliability and adaptability.
2Reliability
If hard plastic protective covers are used, then protection is provided, but manufacturing costs increase
Solution Approach 1:
The patent employs a cost-effective flexible cable tie instead of expensive hard plastic protective covers. The flexible cable tie achieves the necessary connection stability and protection at a lower manufacturing cost, making it an economical solution for securing connectors.
3Reliability
If adjustable tightness is used with flexible cable tie, then connection stability improves, but device complexity increases
Solution Approach 1:
The flexible cable tie is divided into functional segments including a wrapping portion for securing connectors and a fastening portion with snapping portions for adjustable tightness control. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure relatively simple.
Solution Approach 2:
The cable tie incorporates dynamic elements such as adjustable snapping portions that allow the tightness to be modified during assembly. This dynamic adjustment capability enables connection stability to be optimized for different applications without requiring a completely complex structure.

AI summary
A flexible cable tie, an electrical connection structure and a battery are described. The flexible cable tie includes a cable tie body, a first snapping portion and a second snapping portion, the first snapping portion and the second snapping portion. The cable tie body has an unfolded state and a wrapping state. In the unfolded state, the first snapping portion and the second snapping portion are arranged on the same side of the cable tie body; and in the wrapping state, a second end of the cable tie body is connected to the first snapping portion and the second snapping portion. The two snapping portions, can realize dual fixing of the second end of the cable tie body. The two snapping portions are spaced by the preset distance, such that components wrapped by the flexible cable tie can be placed on two sides of the second snapping portion respectively.
