Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping devices have complex and expensive mechanical constructions for adjusting crimp height, making them inefficient and costly.
Innovation Solution
A crimping press with a simple crimp-height adjuster using a rotationally hindered eccentric disk driven by the press motor, which adapts crimper positions for different wire conductor and insulation diameters without displacement during production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex mechanical construction with multiple drives (motor, splined shaft, worm gear, eccentric shaft) is used for adjusting crimp height, then the crimp height can be adjusted, but the device becomes complicated and expensive
Solution Approach 1:
The patent extracts and eliminates the complex mechanical transmission components (splined shaft, worm gear, eccentric shaft) from the crimp height adjustment mechanism, retaining only the essential eccentric disk that directly determines crimp height. This simplification removes unnecessary mechanical complexity while preserving the adjustment function.
Solution Approach 2:
Instead of using a motor to actively drive complex mechanisms to adjust height, the invention inverts the approach by using the press motor's rotational motion to simply rotate an eccentric disk, where the eccentric geometry itself passively creates the height adjustment effect through its offset center, eliminating the need for active mechanical transmission.
2Adaptability or versatility
If multiple adjustment drives are provided for conductor crimper and insulation crimper, then both can be adjusted independently, but the device becomes more expensive
Solution Approach 1:
The patent applies universality by using a single press motor to perform multiple functions: it both drives the crimping operation and adjusts the crimp height through rotation of the eccentric disk. This eliminates the need for separate adjustment drives while maintaining adaptability for different crimping requirements.

Function Achieved in This Case
Enables easy adjustment of crimp height, reducing mechanical complexity and cost, allowing for precise crimping of various wire diameters with improved operational efficiency.
Implementation Method 1
Rotation is imparted to the eccentric disk by means of the press motor which is sufficiently powerful to turn the rotationally hindered eccentric disk

AI summary
In this crimping device, a press slide (5) is provided with a crimp-height adjuster (20) for the insulation crimper (9). The crimp-height adjuster (20) arranged on the press slide (5) above an upper tool (7) consists essentially of a rotationally hindered eccentric disk (21), a lever (22), and a magnet (23) with plunger (24). The eccentric disk (21) is mounted rotatably on an axle (25). During production of crimp connections, the plunger (24) is at rest outside an elongated hole (28) of the lever (22). The press slide (5) with the upper tool (7) can be moved up and down without hindrance. With the plunger (24) inserted into the elongated hole (28) and with an upward motion of the press slide (5), after overcoming the friction of a disk-spring assembly the eccentric disk (21) executes rotational motion in clockwise direction. The lever (22) that is rigidly connected to the axle (25) turns the eccentric disk (21) about the axle (25). The eccentric disk (21) defines the crimp height for the insulation crimper (9).
