Cable Stripping Wheel for Shield-Safe Sheath Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stripping shielded cables often damage the sensitive shielding layer during the stripping process, especially when the shielding layer is made of thin materials like aluminum foil or filigree wire mesh, due to the static friction and deformation caused by the rolling wheel, making it difficult to remove the protective sheath without damaging the shielding layer.
Innovation Solution
A device with a rolling wheel featuring radially protruding perforation elements that wear down the protective sheath without penetrating the shielding layer, combined with a cutting wheel that actively cuts the sheath, ensuring the shielding layer remains intact by controlling the pressure force through adjustable means or centrifugal force, and an electrical continuity check for quality assurance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rolling wheel is used to strip the protective sheath, then the stripping efficiency is improved, but the shielding layer may be deformed or damaged due to pressure forces
Solution Approach 1:
The rolling wheel is equipped with perforation elements that concentrate the stripping action at specific local points rather than distributing pressure across the entire contact surface. This localized action allows the perforation elements to penetrate and sever the protective sheath effectively while the spaces between elements prevent excessive pressure from being applied to the shielding layer, thus resolving the contradiction between stripping efficiency and shielding layer protection.
Solution Approach 2:
The rolling wheel's contact surface is segmented into multiple discrete perforation elements rather than being a continuous rolling surface. This segmentation allows the stripping force to be applied in discrete points, enabling the protective sheath to be severed effectively while reducing the overall contact area and pressure distribution on the shielding layer, thereby preventing deformation or damage.
2Strength
If pressure force is increased to sever the protective sheath, then the stripping capability is improved, but the shielding layer may be damaged
Solution Approach 1:
The pressure force is concentrated at the tips of the perforation elements rather than being distributed across a large contact area. This localized concentration of force allows the protective sheath to be severed effectively with moderate overall pressure, while the small contact area at each perforation element tip prevents excessive pressure from being transmitted to the shielding layer.
Solution Approach 2:
The perforation elements are designed as sacrificial features that penetrate and sever the protective sheath in a single pass, then remain embedded or are removed with the stripped sheath. This disposable approach allows sufficient force to be applied at the perforation element tips to sever the sheath without requiring sustained high pressure that would damage the shielding layer.
3Reliability
If the rolling wheel penetrates deeply to remove the protective sheath, then the stripping completeness is improved, but the shielding layer integrity is compromised
Solution Approach 1:
The perforation elements create localized penetration points through the protective sheath without requiring deep continuous penetration. The sheath is severed at these discrete points, allowing complete removal of the sheath while the shielding layer remains intact between the perforation points, maintaining its structural integrity and functionality.
Solution Approach 2:
The protective sheath is severed into segments by the distributed perforation elements rather than being penetrated continuously. This segmented approach allows the sheath to be completely removed in pieces while the shielding layer maintains its continuity and integrity, as the perforation elements do not traverse the entire depth to the shielding layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively strips the protective sheath of shielded cables without damaging the shielding layer, allowing for easy removal of the shield foil and ensuring the shielding layer's integrity, thus facilitating efficient and reliable cable connection processes.
Implementation Method 1
a plurality of perforation elements are arranged on the rolling wheel on a radially outer rolling contour such that they are distributed over the circumference, which perforation elements protrude radially by a length L from the rolling contour
Implementation Method 2
the static friction between the protective sheath and the shield foil
Implementation Method 3
corresponding pressure forces must be applied to the shield foil by the rolling wheel
Implementation Method 4
the required pressing force for severing the protective sheath can be brought about in a simple manner by the acting centrifugal force

AI summary
A device for stripping cable has a support roller arrangement and a work wheel arrangement. The support roller arrangement is on a rotation base rotatable about an axis of rotation and the work wheel arrangement is on a work wheel guide. The rotation base and the work wheel guide are connected via at least one guide and the work wheel guide is displaceable relative to the rotation base in a guide direction running transversely to the axis of rotation. The support roller arrangement has at least two support rollers each mounted on the rotation base so as to be rotatable about a support roller axis and the work wheel arrangement has a rolling wheel mounted on the work wheel guide so as to be rotatable about a rolling wheel axis. A clamping region is formed around the axis of rotation and between the support rollers and the rolling wheel.
