Cable-Holding Device Sealing Assembly Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable-holding devices with sealing assemblies are inconvenient to assemble and prone to component dropout during installation, leading to inefficiencies and potential water vapor or moisture ingress into junction boxes.
Innovation Solution
A cable-holding device with a sealing assembly that integrates a body, sealing portions, and an adjustment element, where the sealing portions are interconnected and the adjustment element uses clamping arms and oblique bumps to secure the sealing components, preventing dropout and enhancing tightening force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing ring, O-ring and sealing insert are installed as independent components on corresponding locations, then the waterproofing effect is achieved, but the assembling process becomes inconvenient and components may drop out or be lost accidentally
Solution Approach 1:
The patent integrates multiple independent sealing components (sealing ring, O-ring, sealing insert) into a single integrated sealing assembly that is pre-assembled as one unit. This merging of components eliminates the need to install each sealing element separately, thereby improving assembling convenience while maintaining the waterproofing effect through the combined sealing structure.
2Reliability
If sealing ring, O-ring and sealing insert are installed as independent components, then the waterproofing effect is achieved, but component dropout or loss occurs during assembling process
Solution Approach 1:
By combining multiple sealing components into a single integrated sealing assembly, the patent ensures that all sealing elements remain together as one stable unit throughout the assembling process, preventing dropout or loss of individual components while maintaining the waterproofing function.
Solution Approach 2:
The sealing components are pre-assembled into a complete sealing assembly before installation on the cable-holding device. This preliminary assembly ensures that all sealing elements are properly positioned and secured to each other beforehand, preventing component loss during the final installation process.
3Reliability
If adjustment element moves toward first connecting portion, then clamping arms are pushed toward second sealing portion to form tightening state, but the structure becomes more complex
Solution Approach 1:
The patent employs an adjustable clamping mechanism where clamping arms can dynamically change their position and clamping force based on the movement of the adjustment element. This dynamic structure allows the device to adapt to different cable sizes and tightening requirements, ensuring reliable tightening while using a relatively simple adjustment mechanism rather than a complex multi-component system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated sealing assembly improves assembly efficiency, prevents component dropout, and provides a stronger waterproof seal by maintaining a secure tightening state, effectively preventing water vapor or moisture from entering the junction box.
Implementation Method 1
Upon being screwed with the body portion, the gland nut forms compression to the sealing ring, which engages the flexible metallic raceway on the electrical enclosure to achieve sealing and waterproofing

AI summary
A cable-holding device with sealing assembly includes a body having a main unit, a first connecting portion and a second connecting portion, a sealing assembly on the body, and an adjustment element on the second connecting portion. The body has a connecting hole, and the second connecting portion is extended with plural clamping arms. The sealing assembly includes a first sealing portion outside the first connecting portion, a second sealing portion inside the clamping arms to form a tightening port, and a connecting portion between the first sealing portion and the second sealing portion. On the second connecting portion, the adjustment element includes a first movement state which forms a tightening state on the tightening port, and a second movement state which changes the tightening port from the tightening state into a non-tightening state gradually.
