Snap-in Cable Hanger Clip for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snap-in cable hangers face issues with excessive load capacity due to twisting and shifting of legs, leading to disengagement of locking barbs and potential deformation, especially when multiple cables are stacked, which can exceed the structural connection limits.
Innovation Solution
A clip is designed to fit between the legs of the snap-in cable hanger at the mounting hole, immobilizing them and increasing the load capacity by filling the spring space, made from polymer or metal materials with specific dimensions and features to prevent removal and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple cable hangers are stacked to secure more cables, then the quantity of cables mountable increases, but the load on the base connection may exceed the capacity of the snap-in interconnection
Solution Approach 1:
A clip is introduced as an intermediary component between the cable hanger legs and the mounting hole. The clip fills the spring space and prevents the legs from twisting or shifting, thereby mediating the load transfer and preventing disengagement of locking barbs when multiple hangers are stacked
Solution Approach 2:
The cable hanger system is segmented into distinct functional components: the cable hanger itself, the mounting hole, and the clip. This segmentation allows the clip to specifically address the leg stability issue without redesigning the entire hanger structure, enabling increased load capacity while maintaining the snap-in installation advantage
2Ease of operation
If the spring space between legs is left open, then ease of installation is maintained, but the legs may twist and shift under load causing disengagement
Solution Approach 1:
The clip acts as a mediator that fills the spring space without interfering with the snap-in installation process. It provides structural support to prevent leg twisting and shifting under load, thereby improving connection reliability while maintaining ease of installation
Solution Approach 2:
The clip is designed to be installed beforehand or simultaneously with the cable hanger, preliminarily securing the legs in place. This preliminary action prevents potential twisting and shifting before loads are applied, ensuring reliable connection from the outset

AI summary
A clip for a snap-in cable hanger with a top from which at least two clip arm(s) extend and at least one of the clip arm(s) formed with a clip tab projecting proximate a distal end. The top having a length greater than a diameter of the mounting hole and a width dimensioned to fit within a spring space when the snap-in cable hanger is seated upon the mounting hole. The clip arm(s) spaced apart proximate the diameter of the mounting hole, having a length longer than a depth of the mounting hole.
