Inspectable Quick-Connector Cable Gland for Fast Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable gland assemblies are complex and time-consuming to disassemble and reassemble, leading to errors and potential environmental debris entry, which can degrade the cable and reduce the quality of the cable gland.
Innovation Solution
The proposed cable gland assembly features a hub body with a multistart threaded portion, an intermediate body with an annular projection and external threads, and a union nut with a shoulder that secures the intermediate body in place, allowing for quick release and simplifying the disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cable gland assemblies are disassembled for inspection or sealant application, then the cable assembly can be accessed, but numerous components come apart including those that do not need to separate, making the process complex and time-consuming
Solution Approach 1:
The cable gland assembly is divided into modular segments: a hub body that remains stationary, and a removable cable assembly that includes the intermediate body, gland nut, and cable. This segmentation allows only the necessary components to be disassembled for inspection or sealant application, while the hub body and other components remain in place, simplifying the disassembly process and reducing the number of parts that need to be handled.
2Productivity
If conventional cable gland assemblies are disassembled, then inspection or sealant application can be performed, but the process is error-prone and time-consuming
Solution Approach 1:
The intermediate body is pre-configured with an internal passage that aligns with the hub body's internal passage, and the gland nut is pre-threaded onto the intermediate body. This preliminary configuration allows for rapid assembly by simply threading the gland nut onto the intermediate body, which automatically positions all components correctly without requiring complex alignment procedures or multiple assembly steps.
3Reliability
If conventional cable gland assemblies are used, then cable termination is achieved, but environmental debris may enter from mating points, leading to degradation of cable or conductor
Solution Approach 1:
The intermediate body is nested within the hub body, with its internal passage aligned and positioned inside the hub body's internal passage. The gland nut then encloses both the intermediate body and the cable assembly when threaded onto it. This nested configuration creates a hierarchical sealing structure where each component contributes to blocking debris pathways, with the inner components protected by outer components, effectively preventing environmental debris from reaching the cable or conductor.

AI summary
A cable gland assembly includes a hub body, wherein an exterior portion of a second end of the hub body includes a multistart threaded portion. An intermediate body having a first end that is disposed within the hub body, and a second end having an annular projection disposed around an exterior portion of the second end of the intermediate body proximate to the second end of the hub body, the second end having external threads. A union nut defining an internal passage that receives the intermediate body and the second end of the hub body, a first end of the union nut threadedly engages the multistart threaded portion of the hub body. Tightening the union nut along the multistart threaded portion secures the intermediate body in the hub body. A gland nut having a first end that threadedly engages the external threads of the second end of the intimidate body.
