Electric Power Cable Connector Arrangement With Extended Ground Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric power cable connection methods require complex processes and technical skills, and are time-consuming, especially when reconfiguring cables, as they often necessitate cutting and disposing of joints.
Innovation Solution
A connector arrangement featuring concentric conductors surrounded by a ground conductor that extends beyond the power connection portions, improving axial alignment and simplifying the connection process by allowing for a releasable connection without the need for precise alignment of cable conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional parallel sleeve female arrangements with parallel conductor pin male arrangements are used, then correct connection between cables is ensured, but the connection process becomes complex and time-consuming
Solution Approach 1:
The patent employs concentric conductors where one conductor is nested within another, forming a telescopic structure. The inner conductor is received by the outer conductor, creating a nested arrangement that simplifies alignment while maintaining reliable electrical connection. This nesting principle eliminates the need for complex parallel alignment mechanisms.
Solution Approach 2:
The patent transitions from a two-dimensional parallel arrangement to a three-dimensional concentric arrangement. By stacking conductors along the axial dimension, the connector achieves self-alignment through radial symmetry, reducing the complexity of alignment procedures while ensuring correct connection.
2Adaptability or versatility
If traditional connection methods are used, then cable connections can be made, but reconfiguration requires cutting and disposing of joints, increasing time and technical skills required
Solution Approach 1:
The patent creates a dynamic, releasable connection through the telescopic engagement of concentric conductors. The inner conductor can be inserted and removed from the outer conductor, allowing for easy reconfiguration without permanent joints. This dynamic structure enables rapid assembly and disassembly while maintaining connection integrity.
3Device complexity
If concentric conductors are used without extended ground conductor, then connector structure is simpler, but axial alignment of conductors is poor
Solution Approach 1:
The extended ground conductor acts as an intermediary alignment element. It extends beyond the power conductors to provide a reference surface or engagement feature that guides the axial positioning of the inner and outer conductors. This intermediary structure ensures precise alignment without adding complex alignment mechanisms to the power conductors themselves.
