Power Conduction Elements Replace Wires in DC Power Supply

Solution Overview

Problem

Miniaturization of electronic products with larger power supply is hindered by the need for larger diameter connection wires to handle high DC current, which reduces flexibility and increases space occupation, making it difficult to reduce volume while complying with safety regulations.

Innovation Solution

The use of rigid conductive power conduction elements, such as copper or aluminum, to replace conventional large diameter wires for electrical connection between the power input port and the DC/DC conversion circuit, mounted on power transmission boards with corresponding electrical connection pins, allowing for precise placement and reduced space usage.
