Cable Armor Stop Radial Protrusion Conductor Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in accommodating variations in cable sheathing outer diameters while ensuring that electrical conductors can pass through, as smaller diameters to prevent sheathing from passing can impede larger conductors, particularly in installations with larger cables or more numerous conductors.
Innovation Solution
A cable armor stop with a radially protruding member that extends inwardly from the interior surface, allowing electrical conductors to pass while preventing the cable sheathing from passing, and is designed to fit within a range of cable sheathing diameters, with features such as smooth surfaces and shapes like a palatine uvula to minimize abrasion and accommodate different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical connector or cable armor stop has a smaller inside diameter to prevent the cable sheathing from passing, then the cable sheathing is prevented from entering the panel box, but the passage of electrical conductors through the connector becomes extremely difficult
Solution Approach 1:
The cable armor stop features a non-uniform internal diameter along its length, with a smaller first internal diameter at the forward end to block cable sheathing and a larger second internal diameter at the rear end to accommodate electrical conductors. This local variation in dimensional properties allows the same component to perform two opposing functions: preventing sheathing passage while facilitating conductor passage.
Solution Approach 2:
The cable armor stop transitions from a single-diameter design to a multi-diameter design, adding dimensional complexity along the axial dimension. This creates distinct zones (first and second internal diameters) that address different functional requirements at different positions along the component's length.
2Adaptability or versatility
If a smaller inside diameter is used to accommodate smaller cable sheathing variations, then the minimum cable sheathing outer diameter is prevented from passing, but the handling and passage of larger size cables with large diameters and more numerous electrical conductors is impeded
Solution Approach 1:
The cable armor stop employs different internal diameter specifications at different locations: a first internal diameter (0.380 inch) at the forward end for blocking smaller cable sheathing, and a second internal diameter (0.5625 inch) at the rear end for accommodating larger cables and conductors. This spatial differentiation allows adaptation to various cable sizes within the same component.
Solution Approach 2:
The cable armor stop serves multiple functions within a single component: it blocks cable sheathing of varying sizes, accommodates electrical conductors of different quantities and sizes, and provides structural support. The multi-diameter design enables one component to handle the full range of cable configurations.

AI summary
A cable armor stop for preventing cable sheathing of an electrical cable from passing the armor stop while allowing electrical conductors of the electrical cable to pass therethrough has a body with an outer shell, the body having an interior cavity formed by an interior surface of the body, the cavity extending through the body between a front side of the body and a rear side of the body, the cavity reduced by a radially protruding member extending inwardly such that a terminating end of the radially protruding member is spaced a distance from an opposite side of the interior surface closest to the terminating end, the distance being less than a minimum outside diameter of the cable sheathing of said electrical cable. An electrical connector including such a cable armor stop.
