Category 6 Data Cable With Central Filler And Thread Bundles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission cables with SF/UTP structure, designed to meet Category 6 requirements, face difficulties in quick assembly due to the complexity of removing and cutting the plastic cross element after stripping the outer sheath and braided shield, making on-site cable assembly challenging.
Innovation Solution
A data transmission cable design featuring twisted wire pairs with a central filler and equidistantly arranged bundles of auxiliary threads for alignment and fixation, eliminating the need for a plastic cross element, and incorporating a braided shield surrounded by an insulating foil within a polyvinyl chloride or aramid outer jacket, allowing for easier assembly and cutting of components.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a plastic cross element is used to fix wire pair positions, then crosstalk between wire pairs is reduced, but the cable assembly process becomes complex and difficult due to the need to cut off the plastic cross very close to the cable end
Solution Approach 1:
The invention removes the problematic plastic cross element from the cable structure and replaces it with a central filler and bundles of auxiliary threads. This extraction eliminates the need to cut off a complex plastic cross close to the cable end, while the auxiliary threads continue to provide wire pair positioning and alignment functions.
Solution Approach 2:
The invention uses bundles of auxiliary threads that can be easily cut off and discarded after serving their purpose of aligning and positioning the wire pairs during assembly. These threads are simple, inexpensive elements that fulfill their function temporarily and are then removed, unlike the permanent plastic cross that required precise cutting.
2Productivity
If the outer cable sheath and braided shield are stripped to enable quick connection, then cable assembly speed is improved, but the plastic cross element must be cut off very close to the cable end which is complex and difficult
Solution Approach 1:
The invention extracts the plastic cross element that causes assembly complexity and replaces it with a central filler and auxiliary threads. This allows the stripping and cutting operations to be performed cleanly without leaving a complex plastic cross that must be precisely trimmed close to the cable end.
Solution Approach 2:
The auxiliary threads are designed to be discarded after use - they are cut off easily after serving their alignment function during assembly. This is simpler than the plastic cross which must be precisely trimmed and cannot be easily discarded.
3Manufacturing precision
If a central plastic cross is used to align wire pairs, then wire pair positioning is improved, but on-site cable assembly becomes challenging due to the difficulty of cutting the plastic cross
Solution Approach 1:
The invention replaces the permanent plastic cross with temporary auxiliary threads that provide wire pair alignment during assembly but can be easily cut off and discarded. These simple thread elements maintain positioning precision during the assembly process without creating on-site cutting difficulties.
Solution Approach 2:
The invention removes the problematic plastic cross element that requires complex cutting operations and replaces it with a central filler and auxiliary threads that provide equivalent positioning functionality without the cutting complexity.

AI summary
The invention relates to a pre-assembled data transmission cable with multiple wire pairs, each comprising a pair of twisted conductors. Additionally, a central guide wire, surrounded by and adjacent to the wire pairs, is provided, by means of which the wire pairs are aligned with each other. Furthermore, several bundles of guide threads are arranged equidistantly circumferentially around the wire pairs. Each bundle of guide threads is positioned adjacent to two respective pairs of wire. The wire pairs are fixed to each other on the one hand by the central guide wire and on the other hand by the bundles of guide threads.
