Implosion Connector for Composite Transmission Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-steel core transmission lines, such as those with carbon composite materials, have a lower compression failure point compared to steel, making it challenging to securely attach electrical connectors without causing catastrophic damage during radial compression, while maintaining sufficient friction to keep the line suspended.
Innovation Solution
An electrical connector with a compressible sleeve and a compression regulator that includes an implosion section with explosive material to radially or axially compress onto a non-steel core, preventing core crushing and ensuring secure attachment without damage, using sleeves made from materials like steel, aluminum, or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If radial compression is applied to secure the electrical connector to the transmission line, then frictional force is improved, but the non-steel core may be catastrophically damaged
Solution Approach 1:
The patent applies controlled radial compression to transform the sleeve from a loose fit to a tight interference fit around the transmission line conductor. This parameter change creates the necessary frictional force for suspension while the compression regulator ensures the compression remains within safe limits to prevent core damage.
Solution Approach 2:
The compression regulator acts as an intermediary component between the compression force source and the transmission line core. It mediates the compression process by providing a bearing surface that distributes the compressive force, preventing direct concentration of force on the vulnerable non-steel core while still enabling sufficient frictional force generation.
2Reliability
If sufficient compression is applied to maintain suspension, then frictional attachment is improved, but core failure risk increases
Solution Approach 1:
The compression regulator is designed with a bearing surface that provides cushioning protection to the transmission line core before compression is applied. This pre-positioned protective element ensures that when compression occurs, the force is distributed safely and the core is protected from catastrophic failure, while still achieving reliable attachment.
Solution Approach 2:
The compression regulator serves as a protective intermediary between the compression mechanism and the vulnerable non-steel core. It translates the compression force into a safe distribution pattern that maintains attachment reliability without exceeding the core's compression strength limits.
