Universal Cable Lug Connection with Adjustable Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical cable connection methods require multiple connection means for different cable configurations, leading to increased complexity and cost, and do not efficiently manage high current densities.
Innovation Solution
A connection arrangement where a cable lug's end area is accommodated in a receiving area of a cable lug, with a screw passing through, and connected to a socket in a force-fitting, form-fitting, and material-locking manner, allowing for either one or two cable lugs to be connected to a socket, using a composite part with a cover plate, and optionally a second mirror-inverted cable lug for increased current capacity, made from insulating materials like plastic or metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different connection means are used for different cable configurations, then the adaptability to different cable arrangements is improved, but the device complexity and cost increase
Solution Approach 1:
The connection means is designed as a universal component that can accommodate different cable configurations through a standardized interface. The housing with recesses and cover plates can accept one or two cable lugs in various arrangements, eliminating the need for multiple specialized connection means for different cable setups
2Device complexity
If a standardized connection means is used for all configurations, then the device complexity is reduced, but the adaptability to different cable arrangements deteriorates
Solution Approach 1:
The connection means incorporates dynamic configurability through removable cover plates and adjustable recess configurations. The housing can dynamically adapt its internal structure to accommodate either one cable lug or two cable lugs, or different cable orientations, maintaining versatility while using a single standardized component design
3Device complexity
If only one cable lug is connected per socket, then the device complexity is reduced, but the current capacity is limited
Solution Approach 1:
The connection means allows dynamic configuration where the number of cable lugs per socket can be adjusted based on current requirements. The housing design with multiple recesses and removable cover plates enables the user to connect either one or two cable lugs to each socket, providing flexibility to increase current capacity when needed while maintaining simplicity when lower capacity suffices
