Polyhedral Splitter Seat for High-Frequency Cable Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-frequency cable test platforms cause significant damage to the cable structure and are limited in test frequency due to the need for long stripped lengths and vertical bending of cores, which restricts the ability to test multiple pairs of cores simultaneously at higher frequencies.
Innovation Solution
A test platform with a polyhedral splitter seat and inclined splitter channels allows multiple pairs of cores to be tested simultaneously with reduced stripped length, minimizing damage by allocating each pair to a different side and using clamps with hinge points to press conductors against conductive contacts, thereby increasing test frequency beyond 2.4 GHz.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cores are arranged in a same plane for testing, then all cores can be tested simultaneously, but the damage to the cable structure is relative large
Solution Approach 1:
The patent transitions from arranging all cores in a single plane to distributing them across multiple sides of a polyhedral splitter seat. Each side contains conductive contacts arranged in sequences, with cores allocated to different sides rather than all in one plane. This spatial dimensionality change reduces the concentration of stress and damage on any single cable section while enabling simultaneous testing of multiple core pairs.
2Speed
If the stripped length of the cable is shortened, then the test frequency can be increased, but the cable structure integrity becomes more difficult to maintain
Solution Approach 1:
The patent divides the cable core allocation into multiple segments corresponding to different sides of the polyhedral splitter seat. Each side has its own sequence of conductive contacts and can process a subset of cores independently. This segmentation allows the cable to be stripped to a shorter length while distributing the connection points across multiple locations, thereby maintaining structural integrity despite the reduced stripped length and enabling higher test frequencies.
3Productivity
If multiple pairs of cores are tested simultaneously, then testing efficiency is improved, but complete test data is unachievable due to excessive breaking of outer cladding
Solution Approach 1:
The patent uses a polyhedral splitter seat with multiple sides, where each side contains conductive contacts arranged in sequences. Multiple pairs of cores are allocated to different sides rather than all being processed in a single plane. This dimensional distribution allows simultaneous testing of multiple core pairs while maintaining sufficient outer cladding integrity on each side, thereby achieving both high testing efficiency and complete test data.
