Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor connection contacts for printed circuit boards are not compact, easy to handle, or stable, and do not ensure reliable electrical contact while meeting clearance and creepage distance requirements.
Innovation Solution
A conductor connection contact with a plug-in contact connection featuring a spring-clamping element and a solder connection surface, where the connection surface is spaced apart from the solder connection surface, allowing for reliable clamping of electrical conductors and optimizing current paths through spring-elastic clamping tongues and foot sections, with optional insulation displacement contact connections for enhanced mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the connection surface is positioned close to the solder connection surface, then the device complexity is reduced, but the clearance and creepage distance requirements cannot be ensured
Solution Approach 1:
The connection surface is positioned in a direction transverse to the solder connection surface, utilizing the third dimension (height/depth) rather than increasing lateral distance. This vertical separation allows clearance and creepage requirements to be met while maintaining a compact overall structure.
Solution Approach 2:
The contact structure is divided into distinct functional zones: the connection surface area for electrical connections and the solder connection surface area for mechanical attachment. This segmentation allows each surface to be optimized independently for its specific function while meeting spatial requirements.
2Volume of moving object
If a compact design is used, then the volume is reduced, but the handling ease deteriorates
Solution Approach 1:
The contact is segmented into distinct functional areas (connection surface, solder surfaces, clamping elements) that can be independently manipulated during assembly. This modular segmentation facilitates easier handling and assembly despite the compact overall size.
3Reliability
If the connection surface is spaced away from the solder connection surface, then the clearance distances are ensured, but the current-conducting path length increases
Solution Approach 1:
The separation between connection surface and solder connection surface is achieved in the vertical dimension rather than extending the lateral current path. This three-dimensional arrangement maintains short current paths while ensuring adequate clearance distances.
4Device complexity
If multiple functional areas are integrated into one contact, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
While integrating multiple functions into a single contact structure, the design segments the contact into distinct functional zones with clear geometric boundaries. This zonal segmentation provides inherent positioning references that reduce manufacturing precision requirements compared to fully integrated designs.
