Communication Cable Separators with Spaced Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication cables with continuous longitudinal separators face issues of increased material usage and reduced flexibility due to continuous projections, leading to undesirable crosstalk between twisted pairs of conductors.
Innovation Solution
The implementation of separators with longitudinally spaced projections, where projections extend between adjacent twisted pairs with significant gaps, reducing material usage and enhancing flexibility while maintaining effective separation.

Engineering Contradiction Analysis
1Reliability
If continuous projections are used in separators, then separation effectiveness between twisted pairs is improved, but material usage increases and flexibility decreases
Solution Approach 1:
The separator projections are divided into discrete segments spaced at intervals along the longitudinal axis, rather than forming a continuous structure. This segmentation maintains separation effectiveness at critical points while reducing overall material consumption by eliminating projections in non-critical zones.
Solution Approach 2:
Separation is provided locally at specific longitudinal positions where twisted pairs are most susceptible to interlinking, rather than uniformly along the entire length. This allows material to be concentrated where it provides maximum benefit while reducing usage in areas where separation is less critical.
2Reliability
If continuous projections are used in separators, then separation effectiveness between twisted pairs is improved, but flexibility of the cable is reduced
Solution Approach 1:
The continuous separator structure is segmented into discrete projection groups spaced along the longitudinal axis. These gaps between projection groups allow the cable to bend and flex more easily without the constraint of a continuous rigid structure, thereby improving flexibility while maintaining separation where needed.
Solution Approach 2:
The separator structure transitions from a static continuous form to a dynamic segmented form that can adapt to cable bending and movement. The spaced projections allow the separator to flex with the cable while still providing separation effectiveness at critical locations.
3Quantity of substance
If projections are spaced longitudinally with gaps, then material usage is reduced and flexibility is enhanced, but separation effectiveness may be compromised
Solution Approach 1:
Separation effectiveness is optimized locally at the positions where projections are present, targeting the specific zones where twisted pairs are most prone to interlinking. The gaps between projection groups are placed in regions where separation requirements are lower, thus maintaining overall effectiveness while reducing material.
Solution Approach 2:
The separator employs a periodic pattern of projections spaced at intervals along the longitudinal axis. This periodic structure provides separation at regular intervals, which is sufficient to prevent interlinking while allowing material reduction in the gaps between periodic zones.

AI summary
A cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and one or more respective projections extending from the spine at each of a plurality of longitudinally spaced locations. Each projection at a given spaced location may extend between a respective set of adjacent twisted pairs. Additionally, a respective longitudinal gap of at least approximately five centimeters may be present between each adjacent pair of longitudinally spaced locations.
