Formed Wire Wrapping Tool With Pusher for Stiff Cable Inlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stiffness of formed wires makes it difficult for installers to manually wrap the last few turns around electrical conductors or cables, necessitating a tool to facilitate the wrapping process.
Innovation Solution
A tool with a handle and head portion, featuring a pivotable cover and locking system, includes a pusher member that contacts and pushes the formed wire strands to assist in wrapping, allowing for easier completion of the wrapping process around cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If formed wire is used to secure cable to utility pole, then cable can withstand cable sag and environmental conditions, but the stiffness of the steel wire makes it difficult to manually wrap the last few turns
Solution Approach 1:
The patent introduces a wrapping tool as an intermediary device between the installer and the formed wire. The tool includes a handle portion, a head portion with a cable receiving opening, and a pusher member that contacts and pushes the formed wire strands. This intermediary tool overcomes the stiffness of the formed wire by providing mechanical leverage, allowing the installer to complete the wrapping process without directly manipulating the stiff wire with hands.
Solution Approach 2:
The tool incorporates a pivotable cover that can be rotated between an open position (allowing cable insertion) and a closed position (forming the cable receiving opening). The pusher member is movable within the head portion to contact and push the formed wire. This dynamic design allows the tool to adapt its configuration during different stages of the wrapping operation, making it easier to manipulate the stiff formed wire.
2Reliability
If formed wire is pre-formed with spiral shape to distribute force, then operational capability of cable is preserved, but manual manipulation becomes increasingly difficult
Solution Approach 1:
The pusher member acts as an intermediary that contacts the formed wire strands and applies force to advance them through the cable receiving opening and around the cable. This mechanical intermediary overcomes the resistance created by the pre-formed spiral shape, allowing the installer to maintain proper force distribution while completing the wrapping without excessive manual effort.

AI summary
A tool for wrapping a formed wire around a cable is provided. The tool includes a handle portion and a head portion. The handle portion has an elongated body and a hand grip portion attached to the elongated body. The head portion has a cover pivotably attached to a base. When the cover is pivoted into contact with the base a cable receiving opening is formed between the cover and the base. The head portion also includes a pusher member extending from the cover or the base into the cable receiving opening. The pusher member is adapted to contact and push strands of a formed wire when the tool is in use.
