Push-On Cable Securing Device Resisting Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pulling cables through conduits, such as using fish tapes or compression devices, often result in detachment issues during the pulling process, leading to costly and time-consuming reinstallation or conduit removal.
Innovation Solution
A push-on cable securing device with a retaining cap, barrel, and cable receiving component that securely grips cables without compression tools, utilizing a tapered interior wall, fastening ring, and retaining jaw to maintain a secure grasp and resist detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fish tape or compression devices are used to pull cables through conduits, then cable pulling can be achieved, but the risk of detachment during the process increases and reinstallation becomes costly and time-consuming
Solution Approach 1:
The device is divided into distinct functional segments: a barrel for cable insertion, a cable receiving component with gripping elements (retaining jaw, fastening ring, spacer gland) that can be assembled in sequence, and a retaining cap for final securing. This segmentation allows each component to perform its specific function while maintaining overall reliability and ease of assembly.
2Strength
If compression devices are used to secure cable ends, then cable gripping can be achieved, but the device complexity increases and additional tools are required
Solution Approach 1:
The cable receiving component is designed to be self-securing through a push-on mechanism. The retaining jaw, fastening ring, and spacer gland are inserted into the barrel and automatically positioned and secured when the retaining cap is placed over the barrel. No external compression tools or complex assembly procedures are needed, achieving strong cable gripping with simple device structure.
3Reliability
If multiple fastening elements are used to secure cables, then detachment resistance improves, but the number of moving parts increases and assembly complexity increases
Solution Approach 1:
The retaining jaw, fastening ring, and spacer gland are combined into a single cable receiving component assembly that functions together as one unit. These elements are inserted into the barrel in sequence and held in place by the retaining cap, providing multiple gripping points and high detachment resistance while minimizing the number of separate moving parts and simplifying assembly.

AI summary
A cable securing device facilitates secure connection to a cabling end, and employs a retaining cap, a barrel and a cable receiving component. The cable receiving component can include a spacer gland, a fastening ring and a retaining jaw, or a subset thereof, and the elements of the cable receiving component may either be joined together as individual elements or provided as an integrated cartridge.
