Adjustable Cable Lead-Through for Switch Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable lead-throughs for switch cabinets struggle to adapt to cables of different sizes and provide a secure, watertight seal with standardized dimensions, while also being easy to use and handle.
Innovation Solution
The cable lead-through is composed of two identical halves with adjustable inner diameters and clamping devices, made of plastic material, featuring elastic seals and peelable sheets for customization and secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lead-throughs are adapted to standardized dimensions, then they can be easily manufactured and installed, but they cannot adapt to cables of different sizes
Solution Approach 1:
The lead-through incorporates an adjustable inner diameter mechanism that allows the opening size to be dynamically changed to accommodate different cable sizes. This dynamic adjustment capability enables a single standardized lead-through design to adapt to various cable dimensions without requiring multiple fixed-size components.
Solution Approach 2:
The invention changes the parameter of the opening diameter from a fixed value to an adjustable range. By enabling the inner diameter to be modified, the lead-through can accommodate cables of different sizes while maintaining a standardized external form factor for easy manufacturing and installation.
2Reliability
If lead-throughs provide a tight seal against water and moisture, then protection is improved, but the structure becomes more complex with more parts
Solution Approach 1:
The sealing function is integrated directly into the lead-through body structure rather than being a separate component. The adjustable inner diameter mechanism and sealing elements are combined within the single lead-through housing, reducing the total number of parts while maintaining effective sealing against water and moisture.
3Adaptability or versatility
If lead-throughs are designed with adjustable inner diameters, then adaptability to different cable sizes is improved, but manufacturing complexity increases
Solution Approach 1:
The lead-through is divided into two substantially identical halves that can be manufactured separately using standardized processes. Each half contains simplified features that, when assembled, create the adjustable inner diameter mechanism. This segmentation allows for easier manufacturing of individual components while achieving the complex adjustable functionality in the final assembly.

AI summary
A cable lead-through is disclosed for a switch cabinet, electric cabinet or the like. In at least one embodiment, the cable lead-through is formed of two substantially identical lead-through halves. The lead-through halves are held together by way of two clamping devices. By placing the clamping devices in grooves of the lead-through halves, the cable lead-through is held together.
