Variable Diameter Cable Receiving Member for High Power Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection terminals have a narrow transition region between the conductor receiving and contacting areas, limiting the transmission power due to their design, which restricts the application of higher power levels to electronic devices.
Innovation Solution
A connection terminal with a connector body, contact arms, and a cable receiving member of variable diameter, equipped with a compressible sleeve and clamping slots, allows for secure and efficient connection of cables with different diameters, enhancing the transmission of large current signals by increasing the contact area and ensuring reliable electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a narrow transition region is used between conductor receiving region and contacting region, then the device complexity is reduced, but the power transmission capacity is limited
Solution Approach 1:
The cable receiving member transitions from a narrow 2D transition region to a 3D cylindrical structure with variable diameter, expanding the contact area in multiple dimensions to accommodate larger current transmission while maintaining structural integration
Solution Approach 2:
The cable receiving member's diameter varies along its length, with a larger diameter at the cable receiving end and a smaller diameter at the contacting region, optimizing both mechanical strength and electrical contact area for high power transmission
2Manufacturing precision
If a fixed diameter cable receiving member is used, then the manufacturing precision is improved, but the adaptability to different cable diameters is reduced
Solution Approach 1:
Different sections of the cable receiving member have different diameters tailored to specific functions: a larger diameter portion for accommodating various cable sizes and a smaller diameter portion for optimal electrical contact, with each section optimized for its local requirement
Solution Approach 2:
The cable receiving member's variable diameter creates a dynamic adaptation capability, allowing it to securely hold cables of different diameters through its graduated cross-section while maintaining precise dimensional control in each segment
3Power
If a larger contact area is created to transmit larger current signals, then the power transmission capacity is improved, but the device complexity increases
Solution Approach 1:
The cable receiving member integrates multiple functions into a single component: cable support, electrical contact, and current transmission pathways, eliminating the need for separate structures and reducing overall device complexity while providing large contact area
Solution Approach 2:
The variable diameter cable receiving member serves multiple purposes simultaneously: accommodating different cable diameters, providing electrical contact, and facilitating current flow, making the structure universally applicable while maintaining simplicity
