Cable Shield Straightening Device for Braided Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing electrical cables, particularly braided cable shields, struggle with efficiently straightening or unbraiding them for assembly, leading to uneven resting on support sleeves and inadequate connector connections, which affects mechanical and electrical stability.
Innovation Solution
A device with drivable brushes distributed along the cable's circumference, fixed by a clamping device, brushes the braided cable shield to align strands linearly, and a pliers-like tool radially expands the shield for easier sleeve insertion, ensuring even processing without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual brushing method is used to straighten braided cable shield, then strands can be aligned, but automation is lost and processing efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical brushing with an automated mechanical brushing system. A rotating brush with bristles automatically contacts and straightens the braided cable shield strands as the cable moves through the processing device, eliminating manual operation while maintaining effective strand alignment.
Solution Approach 2:
The processing device performs self-service automation where the rotating brush automatically straightens the braided shield without requiring manual intervention. The system feeds itself through continuous cable movement and automatic brush rotation, achieving both quality strand alignment and processing automation.
2Productivity
If braided cable shield is processed without unraveling, then processing speed increases, but connector connection stability deteriorates
Solution Approach 1:
The patent applies preliminary action by straightening and aligning the braided cable shield strands before the connector assembly process. The rotating brush pre-processes the shield to create uniform strand alignment, ensuring that subsequent connector installation achieves reliable mechanical and electrical connections without requiring post-processing adjustments.
3Ease of operation
If radial expansion of braided shield is applied, then sleeve insertion becomes easier, but device complexity increases
Solution Approach 1:
The patent merges the radial expansion function into the existing rotating brush mechanism. The same brush that straightens the strands also provides radial expansion through its rotational contact and applied pressure, eliminating the need for separate expansion devices and reducing overall system complexity while improving sleeve insertion ease.
