Twisted Connecting Wire Structure for Lower Inductance Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in inductance on the current transmitting and receiving path due to the use of larger diameter connecting wires for current transmission results in significant losses, necessitating a reduction in inductance to enhance efficiency.
Innovation Solution
The connecting wire is designed with multiple thin wires in each group, twisted in opposite directions to form multiple current paths, reducing the spacing and inductance by using thinner wires and connecting them in parallel, with a bundle sleeve for protection and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If larger diameter connecting wires are used to transmit current, then current transmission capability is improved, but inductance increases causing energy loss
Solution Approach 1:
The patent divides the wire diameter into multiple thin wires (first thin wires and second thin wires) while maintaining the same total cross-sectional area for current transmission. This segmentation allows the thin wires to be twisted together with smaller spacing, reducing inductance while preserving current transmission capability.
Solution Approach 2:
The patent transitions from a single-dimension wire structure to a multi-dimensional twisted structure by twisting multiple thin wires around each other. This dimensional change reduces the spacing between conductors carrying opposite currents, thereby reducing inductance while maintaining the same current transmission capacity.
2Reliability
If larger diameter wires are used, then current transmission safety is improved, but spacing between wires increases leading to higher inductance
Solution Approach 1:
The patent segments the wire into multiple thin wires that are twisted together, maintaining the same total current transmission capacity as a single thick wire. This segmentation enables closer spacing between conductors with opposite currents, reducing inductance while preserving transmission safety.
Solution Approach 2:
The patent creates a composite wire structure by combining multiple thin wires with different current directions into a single twisted assembly. This composite structure achieves both low inductance (through close spacing) and high reliability (through sufficient total conductive area).

AI summary
The present invention provides twisted connecting wires for connecting a power supply device and an electronic device and transmitting current. The twisted connecting wires include a first wire group and a second wire group. The first wire group includes a plurality of first thin wires, and each of the first thin wires has a first twisted section. The second wire group includes a plurality of second thin wires, and each of the second thin wires has a second twisted section. The number of the second thin wires is the same as the number of the first thin wires, the current directions of the first thin wires and the second thin wires are opposite, and the first twisted sections and the second twisted sections are twisted one-to-one. The spaces between the first thin wires and the second thin wires after they are twisted becomes smaller, thereby reducing the total inductance.
