Cable Stripping Tool Parts With Helical Blades and Sheath Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping tools face challenges in efficiently removing insulating sheaths, often requiring manual removal and resulting in jammed insulation portions that are time-consuming to detach, especially when using helical cutting patterns.
Innovation Solution
The tool parts feature blades that form a helical cutting pattern when moved together, with additional blades for transverse cutting and ejection mechanisms like spring elements or deformation projections to facilitate easy removal of insulating sheaths, ensuring complete exposure of the cable core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If helical cutting pattern is used to cut insulating sheath, then cutting efficiency is improved, but insulating portions become jammed and difficult to remove
Solution Approach 1:
The insulating sheath is cut into multiple separate strips by the helical blade pattern instead of one continuous piece, allowing each strip to be independently removed and preventing jamming in the receiving region
Solution Approach 2:
The insulating portions are completely severed and extracted from the receiving region through the ejection means (spring element or deformation projection) that pushes them out, eliminating the jamming problem entirely
2Device complexity
If manual removal of insulating portions is used, then tool complexity is reduced, but time consumption increases
Solution Approach 1:
The tool performs the ejection of insulating portions automatically through spring elements or deformation projections that self-activate during the cutting cycle, eliminating the need for manual removal operations
Solution Approach 2:
The ejection means is pre-positioned in the receiving region to automatically push out insulating portions immediately after cutting, preventing them from jamming and eliminating subsequent removal steps
3Manufacturing precision
If blades extend into cable core for complete separation, then stripping completeness is improved, but risk of cable core damage increases
Solution Approach 1:
The blades have different configurations in different regions: they extend into the cable core at the cutting edges for complete separation, but have limited extension in the receiving region to prevent damage to the cable core while still achieving complete insulating portion removal
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
This design enables efficient and favorable handling of insulating portions, allowing for easy separation and removal of cut strips, reducing the risk of jamming and simplifying the stripping process, suitable for various cable diameters and insulating materials.
Implementation Method 1
a spring element (38) arranged in the bottom region (29) of each tool part (6, 7), by means of which spring element (38) an insulating portion (11) enclosed in the receiving region (13) can be acted upon and thus ejected from the tool part (6, 7)
Implementation Method 2
a deformation projection (36) projecting from the bottom region (29) of each tool part (6, 7) and protruding into the receiving region (13) of each tool part (6, 7), by means of which deformation projection (36) an insulating portion (11) enclosed in the receiving region (13) can be acted upon and thus ejected from the tool part (6, 7)
Implementation Method 3
each tool part (6, 7) has a plurality of blades (15) pointing inwards in the receiving region (13), whose blade tips (16) leave a clearance (17) pointing inwards

AI summary
A pair of tool parts which include a first and a second tool part, can be secured exchangeably in tool jaws of a hand-held tool and can be moved together by means of the tool jaws, for enclosing a cable, encapsulated with an insulating sheath, over a part of a length of the cable. A receiving region of the tool parts formed when moved together, encloses a semi-circular region of the cable in cross section with a longitudinal dimension and a transverse dimension remains for the cable in each tool part. The receiving region is penetrated by a blade and has an inwardly pointing clearance. A plurality of blades are configured in each tool part, and the blade tips run in accordance with a helical line when the tool parts are moved together. Methods for stripping a cable are also provided.
