Dual Strain Relief Cable Connection for Complex Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable connection devices lack reliable solutions for secure mechanical fixation and strain relief of complex electrical cable arrangements, such as multi-core cables and individual conductors, especially when routed in flexible tubes.
Innovation Solution
The cable connection device employs a dual strain relief system with a first and second strain relief component, allowing for secure fixation and strain relief of electrical cables by utilizing positive coupling elements and form-fitting or clamping mechanisms to prevent pulling, pushing, and twisting, and can be easily attached to the housing without specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single strain relief component is used, then the device complexity is reduced, but the reliability of fixation for complex cable arrangements is insufficient
Solution Approach 1:
The cable strain relief device is divided into multiple independent strain relief components (first strain relief component and second strain relief component), each capable of fixing different parts of the cable arrangement. This segmentation allows reliable fixation of complex cable arrangements while keeping each individual component relatively simple in structure.
2Reliability
If multiple strain relief components are used, then the fixation reliability is improved, but the device complexity increases
Solution Approach 1:
Each strain relief component is designed with universal functionality to fix different types of cable parts (conductors, multi-core cables, flexible tubes). The components can be used independently or in combination, providing multi-functional capability that reduces the need for specialized components for each cable type.
3Reliability
If a complex cable arrangement is fixed, then the strain relief reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The cable arrangement is divided into different parts (first part and second part), each fixed by a corresponding strain relief component. This segmentation allows installers to work with smaller, more manageable sections of the cable arrangement independently, improving ease of operation while maintaining reliable fixation of the complete complex arrangement.
