Micro AC Power Inlet Layout for Thin IEC 60320 Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IEC 60320 standard for mains power interconnection couplers restricts the design of compact electrical and electronic products due to its outdated dimensions and shape, which are not compatible with the growing demand for portable and space-efficient devices.
Innovation Solution
The development of a mains AC power inlet with a recessed cavity of less than 7 mm in height, along with matching connectors, allowing for a significant reduction in size while maintaining compliance with IEC 60320 regulations for safety and thermal requirements, enabling the creation of micro-inlets and micro-connectors that are thinner and more compact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If standard IEC 60320 inlets are used, then safety and compatibility are ensured, but device size and thickness increase
Solution Approach 1:
The patent applies parameter changes by reducing the inlet height from the standard IEC 60320 dimension to less than 7mm, while adjusting the pin configuration (two pins of 2.5mm diameter with specific spacing) and insulation material thickness to maintain electrical safety and compliance with current and voltage requirements
Solution Approach 2:
The patent transitions from the traditional horizontal pin arrangement to a vertical pin arrangement within the inlet, allowing the pins to be positioned in a compact vertical space within the reduced-height inlet while maintaining proper clearance and creepage distances for safety
2Adaptability or versatility
If standard IEC 60320 inlets are used, then electrical connectivity is ensured, but design flexibility and portability are reduced
Solution Approach 1:
The patent changes the dimensional parameters of the inlet by reducing its height to less than 7mm, enabling thinner device designs while maintaining electrical connectivity through optimized pin configuration and insulation design that meets safety standards
Solution Approach 2:
The patent segments the inlet structure into distinct functional zones: the recessed cavity for pin insertion, the insulation material layer for electrical isolation, and the housing structure for mechanical support, allowing each segment to be optimized independently for compactness and safety
