Cable Clamping Device for Braided Shield Widening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for widening braided shields in cables, such as coaxial cables, often result in uneven expansion and potential damage to the shield, as they lack uniform force distribution and are not adaptable to various cable diameters and types.
Innovation Solution
A cable clamping device with at least three equilateral polygon-shaped clamping bodies that adjust synchronously to form a variable passage, ensuring uniform widening of the braided shield by changing the circumference and diameter of the passage, thereby distributing force evenly and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If compressed-air jets are used to widen the braided shield, then the shield can be expanded, but the expansion is uneven and damage may occur
Solution Approach 1:
The clamping device divides the braided shield into multiple segments by introducing multiple clamping elements (at least three clamping bodies) that independently contact different portions of the shield. Each clamping element applies localized radial force, ensuring uniform segment-by-segment expansion rather than concentrated force from compressed air, thereby preventing damage and achieving even widening.
Solution Approach 2:
The clamping device applies localized radial clamping forces at multiple discrete points around the cable circumference through individual clamping elements. This distributed local action ensures uniform stress distribution across the braided shield, preventing the uneven expansion and concentrated stress points that occur with compressed-air methods, thus avoiding shield damage.
2Adaptability or versatility
If fixed-size clamping devices are used, then the structure is simple, but they cannot accommodate different cable diameters and types
Solution Approach 1:
The clamping device incorporates adjustable clamping elements that can dynamically change the passage dimensions to match different cable diameters. The clamping bodies are positioned on adjustable mechanisms (such as radial adjustment screws or movable mounts) that allow the passage size to be customized for each cable type, providing versatility without requiring multiple fixed devices.
Solution Approach 2:
The clamping device is designed as a universal tool that can process multiple cable types and diameters through adjustable clamping elements. By incorporating adjustment mechanisms that allow reconfiguration of the passage size, a single device performs the function of multiple fixed-size devices, achieving multi-functionality while maintaining operational simplicity.
3Force
If radial clamping force is applied to widen the shield, then the shield expands, but force distribution is uneven causing damage
Solution Approach 1:
The total radial clamping force is segmented into multiple smaller forces applied by individual clamping elements positioned around the cable circumference. This segmentation ensures that no single point experiences excessive force, and the distributed forces combine to produce uniform radial expansion of the braided shield, preventing damage while achieving the required widening.
Solution Approach 2:
Each clamping element applies localized radial force at specific points around the cable, with the force magnitude and distribution optimized for uniform expansion. The local application points are strategically positioned to ensure even stress distribution across the entire shield circumference, transforming the concentrated force problem into a distributed quality solution.
