Split Sleeve Cable Installation Tool Guide Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Split sleeves with a longitudinal opening tend to roll up and secure cables, making it difficult to quickly and reliably insert cables due to the absence of externally applied forces, which complicates cable installation and maintenance.
Innovation Solution
A tool with arcuate lateral extensions and guide slots is designed to assemble with the split sleeve, allowing for easy cable insertion by sliding along the sleeve's sides and utilizing resilient flaps to facilitate cable placement within the sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the split sleeve is configured to roll up and secure cables automatically, then cable security is improved, but cable insertion difficulty increases
Solution Approach 1:
The patent introduces a compression tool as an intermediary device that temporarily applies external force to the split sleeve during cable insertion. The tool includes compression members that can be positioned on opposite sides of the sleeve to apply controlled compression, preventing the sleeve from rolling up during the insertion process and enabling cables to be passed through the opening without resistance.
Solution Approach 2:
The patent applies preliminary action by using the compression tool to pre-compress the split sleeve before cable insertion. This preliminary compression maintains the sleeve in an open state during the insertion process, and the sleeve is designed to automatically expand to its secured state after the tool is removed, ensuring both easy insertion and reliable cable retention.
2Reliability
If the split sleeve automatically closes to secure cables, then cable retention is improved, but insertion speed decreases
Solution Approach 1:
The compression tool serves as a mediator that temporarily overrides the sleeve's automatic closing mechanism during insertion. By applying controlled compression forces through the tool's compression members, the sleeve remains in an open state allowing rapid cable passage, then automatically returns to its closed retention state when the tool is removed.
Solution Approach 2:
The patent employs dynamics by designing the split sleeve with dynamic properties that allow it to transition between open and closed states. The sleeve material and structure are configured to be compliant under compression (allowing opening) but naturally return to a closed, secured state when compression is released, enabling both fast insertion and reliable retention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool enables rapid and secure insertion of cables into the split sleeve, maintaining organization and ease of maintenance by preventing unintentional cable exit and simplifying the process of securing cables within the sleeve.
Implementation Method 1
At least one resilient flap may extend away from at least one of the first connection portion or the second connection portion. The at least one flap may be configured to deflect toward or away from the cable slot.

AI summary
A tool (100, 100', 300, 400) for installing cables (C) in a split sleeve (10, 210) includes first (110a, 110a', 320a, 410a) and second (110b, 110b', 320b, 410b) guide portions, a third arcuate guide portion (120a, 120a', 310a, 420a) extending from and positioned radially outward of the first guide portion, the first and third guide portions forming a first guide slot (160a, 360a, 460a) therebetween, and a fourth arcuate guide portion (120b, 120b', 310b, 420b) extending from and positioned radially outward of the second guide portion, the second and fourth guide portions forming a second guide slot (160b, 360b, 460b) therebetween. The tool may be assembled to a split sleeve that is biased toward a rolled up configuration. A user may slide the tool along the split sleeve to position the cables within the split sleeve.
