Terminal Crimping Device Interval Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal crimping methods involving band plate carriers often result in terminal displacement due to internal stress from bending, leading to misalignment and poor crimp connections between terminals and electric wires.
Innovation Solution
A terminal crimping device and method that divides terminals into sets, cuts them from the carrier, adjusts their interval, and conveys them to a crimp position for precise alignment and crimping, eliminating the influence of internal carrier stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the coupled part in the carrier is bent to shorten the terminal interval, then the terminal interval can be adjusted to match the wire interval, but internal stress accumulates in the carrier causing deformation and terminal displacement at the crimp position
Solution Approach 1:
The invention divides the terminal coupled body into multiple terminal sets (groups of 2-5 terminals) and processes each set independently. By cutting and conveying terminals set by set rather than as a complete carrier, the system achieves precise interval adjustment without the need to bend the entire carrier, thus avoiding internal stress accumulation and terminal displacement.
Solution Approach 2:
The invention performs preliminary cutting and interval adjustment of terminals before the crimping operation. By pre-adjusting the terminal intervals to match the wire intervals through cutting and selective conveyance, the system ensures proper alignment is achieved before crimping occurs, eliminating the need for post-adjustment bending that would cause stress and displacement.
2Ease of manufacture
If terminals are crimped while still attached to the carrier, then the process is simpler, but terminal displacement occurs due to internal stress from previous bending operations
Solution Approach 1:
The invention extracts terminals from the carrier by cutting them into separate terminal sets before the crimping operation. This extraction removes the source of internal stress (the carrier) that would otherwise cause deformation and misalignment during crimping, while still maintaining process efficiency through automated cutting and conveyance mechanisms.
Solution Approach 2:
The invention performs preliminary cutting and interval adjustment of terminals before crimping. By pre-adjusting terminal positions and removing them from the carrier beforehand, the system ensures terminals are properly aligned and free from carrier-induced stress before the actual crimping operation, achieving both precision and operational simplicity.
3Reliability
If the terminal interval in the carrier is made wider than the wire interval, then terminals can be separated during crimping, but additional cutting and conveying steps are required
Solution Approach 1:
The invention segments the terminal coupled body into terminal sets with intervals wider than the final wire spacing. This segmentation enables subsequent cutting and independent conveyance of each set to the appropriate wire position, providing reliable terminal separation capability while managing device complexity through modular processing of smaller terminal groups rather than entire carriers.
