Adjustable Stripping Pliers Transition Point for Cable Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stripping tools for electrical cables often fail to adjust the length of the stripping stroke effectively, leading to incomplete removal of the insulating sleeve, which can cause strands to fan out and complicate connections, and may result in damage to the electrical wire during storage or connection processes.
Innovation Solution
The design of stripping pliers includes a cutting stroke, a stripping stroke, and a free stroke, with an adjustable transition point between the stripping and free strokes, allowing for individual adjustment of the stripping stroke length and ensuring the stripping blades do not interfere with the freed electrical wire, thus preventing strand damage and facilitating complete sleeve removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stripping stroke length is fixed and not adjustable, then the device structure is simple, but the stripping tool cannot adapt to different cable diameters and sheeting thicknesses, resulting in incomplete sleeve removal or strand damage
Solution Approach 1:
The patent implements a dynamically adjustable stripping stroke mechanism where the transition point between stripping stroke and free stroke can be positioned at different locations along the longitudinal axis. This allows the stripping tool to adapt to various cable diameters and sheeting thicknesses by adjusting the stripping stroke length, resolving the contradiction between adaptability and structural simplicity.
2Reliability
If the stripping stroke is extended to completely remove the sleeve, then complete insulation removal is achieved, but the strands may fan out and complicate connection processes
Solution Approach 1:
The patent applies partial action by allowing the user to adjust the stripping stroke length to match the actual insulation thickness. The stripping stroke can be set to exactly remove the sleeve without excessive movement that would cause strand fanning, while still achieving complete insulation removal. This resolves the contradiction between reliable sleeve removal and ease of connection.
3Ease of operation
If the stripping stroke is shortened to prevent strand fanning, then connection process is simplified, but the sleeve may not be completely removed, leaving insulation on the wire
Solution Approach 1:
The adjustable transition point mechanism allows the stripping stroke length to be dynamically matched to the specific cable and insulation thickness being processed. This ensures that the stripping stroke is long enough to completely remove the sleeve while not being excessively long to cause strand fanning, thereby achieving both complete removal and ease of connection.
4Productivity
If the stripping blades remain in contact with the electrical wire after stripping, then the stripping action is continuous, but the blades may damage the freed wire or strands
Solution Approach 1:
The patent segments the blade movement into two distinct phases: the stripping stroke phase where blades contact and remove the insulation, and the free stroke phase where blades move away from the wire. This segmentation ensures continuous productivity during stripping while preventing blade contact damage to the exposed wire during the return stroke.

AI summary
A stripping tool is formed by stripping pliers. In use, the stripping tool is closable with a closing stroke having a cutting stroke part, a stripping stroke part and a free stroke part. In the cutting stroke part, a closing movement moves at least one stripping blade into a closed position so that the stripping blade cuts into the insulating sheeting of a cable to be stripped. During the stripping stroke part, the cut insulating sheeting is partially stripped from the cable. In the free stroke part, the stripping blades are laterally passed alongside the partially stripped part of the insulating sheeting. A transition point from the stripping stroke part to the free stroke part is adjustable so that it is possible to change the length over which the separated part is partially stripped without any change of the length of the closing stroke of the stripping tool.
