Hook Knife Guard Body for Conductor Insulation Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook knives for stripping insulator material from electrical conductors require skilled operation to avoid damaging the conductor core and often involve multiple steps, with a risk of damaging surrounding objects.
Innovation Solution
A hook knife design featuring a guard body with u-shaped channels and slots that guide the blade to facilitate precise cutting of insulation layers without damaging the conductor core, allowing for both circumferential and axial cuts with improved safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional hook knife without guard is used, then the blade can freely access the conductor for cutting, but the risk of damaging the conductor core and surrounding objects increases
Solution Approach 1:
A guard body is introduced as an intermediary component between the operator and the conductor. The guard body includes a blade receiving portion that guides the blade and a conductor receiving portion that positions the conductor, preventing direct contact between the operator and the conductor core while enabling precise cutting operations.
2Manufacturing precision
If skilled operation is required to avoid damaging the conductor core, then cutting precision can be achieved, but the complexity of operation increases
Solution Approach 1:
The guard body is designed to automatically position and guide both the blade and conductor during operation. The blade receiving portion and conductor receiving portion work together to ensure proper alignment and depth control, allowing the tool to guide itself and reducing the skill level required by the operator to achieve precise cuts without damaging the conductor core.
3Productivity
If multiple cutting steps are used to remove insulation, then complete insulation removal can be achieved, but the time required for operation increases
Solution Approach 1:
The guard body is designed with universal applicability for different conductor sizes and insulation thicknesses. The blade receiving portion can accommodate various blade types and configurations, allowing a single tool design to perform multiple cutting functions (circumferential cutting, axial cutting, insulation removal) without requiring multiple specialized tools or repeated operational steps.

AI summary
A hook knife, a method of using the hook knife, and a guard body are provided. The hook knife includes a handle and a blade extending from the handle. A guard body is coupled to the handle and disposed about the blade, the guard body defining a first u-shaped channel extending perpendicular to the blade, the blade being at least partially disposed within the first u-shaped channel.
