Two-Part Soldering Aid for Precise PCB Stranded Core Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soldering aids for securing stranded cores of cables on printed circuit boards are inefficient in automating the process for large numbers of small-diameter stranded cores, particularly in aligning and holding them in a defined position for soldering.
Innovation Solution
A two-part soldering aid comprising an outer part with a receptacle and an inner part that is displaceably received inside the receptacle, allowing for alignment and secure fastening of the stranded core on the printed circuit board contact surface, enabling efficient automated processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-piece soldering aid is used to secure stranded cores, then the device structure is simple, but the alignment precision and reproducibility of stranded core positioning deteriorates
Solution Approach 1:
The soldering aid is divided into two separate parts: an outer part with an insertion opening and an inner part with a receptacle. The inner part can be displaced relative to the outer part, allowing independent positioning adjustment. This segmentation enables precise alignment of the stranded core through the insertion opening while maintaining a relatively simple overall structure.
2Ease of operation
If manual positioning of stranded cores is used, then the positioning can be adjusted, but the productivity and automation efficiency deteriorates
Solution Approach 1:
The inner part of the soldering aid is designed to be displaceable relative to the outer part, creating a dynamic positioning system. This allows the inner part to be adjusted to different positions during automated assembly, enabling flexible positioning of stranded cores while maintaining high throughput through automation-compatible design.
3Productivity
If multiple stranded cores are soldered in parallel, then the productivity improves, but the alignment precision and position reproducibility deteriorates
Solution Approach 1:
The soldering aid design with displaceable inner part serves multiple functions: it provides precise positioning for individual stranded cores, maintains alignment accuracy for contact surfaces, and enables parallel processing of multiple cores. The universal design allows the same mechanism to handle multiple stranded cores simultaneously while preserving positioning precision through the displaceable inner part that can be independently adjusted for each core.

AI summary
A soldering aid for securing a stranded core of a cable on an electrical contact surface of a printed circuit board includes an outer part having a receptacle and a bearing surface, and an inner part that is displaceably received inside the receptacle of the outer part. The inner part has an access opening through which the contact surface is accessible and can be fastened to the outer part in an assembly position. In an inserted position of the inner part in the outer part, an insertion opening in the inner part is aligned with an insertion opening in the outer part for inserting the stranded core of the cable.
