Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor connection contact elements for clamping electrical conductors on circuit boards face challenges in providing stable and secure mechanical fastening, particularly in resisting transverse forces and preventing conductor slippage, especially when surface-mounted as SMD components without an encompassing housing.
Innovation Solution
The conductor connection contact element features a sheet metal part with a protruding material portion bent over curved regions to form SMD-solder contacts, which are configured to provide additional stability and guidance, allowing for secure soldering and improved mechanical fixation by creating a widened contact area and oblique conductor guiding base for easier conductor insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conductor connection contact element is configured as SMD component without encompassing housing, then the ease of manufacture and cost-effectiveness are improved, but the mechanical stability and resistance to transverse forces deteriorate
Solution Approach 1:
The contact element is divided into functionally distinct segments: the conductor guiding base with oblique orientation for insertion guidance, the curved region for bending the material portion, and the SMD-solder contact for mechanical fastening. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity suitable for SMD manufacturing without encompassing housing.
2Stability of the object's composition
If the material portion is bent over curved region to form SMD-solder contact, then the mechanical stability and resistance to transverse forces are improved, but the device complexity increases
Solution Approach 1:
The SMD-solder contact is merged with the conductor guiding base as a single integrated sheet metal part. The material portion that forms the SMD-solder contact is bent over the curved region but remains part of the same component, eliminating the need for separate parts and assembly steps. This merging maintains mechanical stability while avoiding the complexity of multi-component construction.
Solution Approach 2:
The curved region introduces a controlled curvature in the sheet metal part to form the SMD-solder contact. This curvature provides the necessary mechanical stability and resistance to transverse forces, while the smooth bending geometry is compatible with conventional sheet metal processing methods, avoiding excessive device complexity.
3Ease of operation
If the conductor guiding base is oriented obliquely, then the ease of operation for conductor insertion is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The conductor guiding base is oriented at a specific oblique angle relative to the conductor inserting direction, changing the geometric parameter of the base orientation. This oblique orientation facilitates easier conductor insertion by guiding the conductor at an optimal angle, while the angle is designed to be achievable with conventional manufacturing tolerances for sheet metal parts.
