Crimping Tool Guide Groove for Multi-Core Cable Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping tools for multi-core cables require manual 180-degree bending of non-crimping cable cores, leading to length differences, damage, and difficult handling, especially at manual workstations.
Innovation Solution
A crimping tool with a guide groove that allows non-crimping cable cores to be bent at 90 degrees, reducing length differences and protecting the cables from damage, while ensuring easy insertion and processing by guiding them in a transverse groove adjacent to the crimping area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cable cores are bent by 180 degrees to prevent damage during crimping, then protection against damage is improved, but length differences between cable wire ends exceed permissible tolerance range
Solution Approach 1:
The guide groove is divided into multiple sections: a first guide groove section with a first bending radius for the initial bend, and a second guide groove section with a second bending radius for the final positioning. This segmented approach allows controlled bending that prevents damage while maintaining length precision within tolerance ranges.
2Stability of the object's composition
If cable cores are bent by 180 degrees to lie tightly against the cable, then stability of cable position is improved, but cable cores can relax and be damaged during processing
Solution Approach 1:
The guide groove acts as an intermediary structure that provides continuous support to the cable core during the bending and crimping process. The groove geometry ensures the cable core remains positioned without excessive bending, preventing both relaxation and damage while maintaining stability throughout processing.
3Object-affected harmful factors
If cable cores are bent by 180 degrees, then protection against damage during processing is improved, but insertion and handling through protective housing slots becomes difficult and time-consuming
Solution Approach 1:
The guide groove changes the bending parameter from 180 degrees to a more gradual curve with defined bending radii. This parameter change makes the cable core more flexible and easier to insert through protective housing slots while still providing adequate protection during the crimping process.
