Electric Connection Protection Box with Integrated Cable Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection boxes for electric connections lack effective and affordable solutions for securely locking cables while providing protection against water sprays or liquids.
Innovation Solution
A protection box design featuring two half-shells with internal compartments and cable clamps, where the half-shells are hinged and feature 'U-shaped' extensions and cavities for secure cable locking, and a screw mechanism for fixing the mobile jaw of the cable clamps, ensuring effective sealing and adaptability to cable diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable locking mechanisms are used, then cable security is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the cable clamp and sealing functions into a single integrated component. The L-shaped clamp simultaneously secures the cable and creates a water-tight seal against the half-shell, eliminating the need for separate sealing elements and reducing overall device complexity while maintaining both cable security and waterproofing
Solution Approach 2:
The patent uses a flexible sealing element that conforms to the cable surface and creates a water-tight seal. This flexible approach allows effective sealing against water sprays without requiring complex rigid sealing structures, thereby maintaining simplicity while achieving the waterproofing function
2Reliability
If robust cable locking is implemented, then cable security is improved, but ease of manufacture deteriorates
Solution Approach 1:
The L-shaped clamp integrates both the securing function and sealing function in one piece, which can be manufactured as a single molded component. This reduces the number of parts to be assembled and simplifies the manufacturing process while maintaining effective cable locking and waterproofing
Solution Approach 2:
The clamp is made from a single homogeneous material that provides both mechanical strength for cable securing and flexibility for sealing. This uniform material approach simplifies manufacturing compared to multi-material constructions that would require complex assembly processes
3Object-affected harmful factors
If waterproof sealing is enhanced, then protection against water sprays is improved, but device complexity increases
Solution Approach 1:
The patent employs a flexible sealing element that naturally conforms to the cable surface and creates an effective water-tight seal. This flexible approach provides robust waterproofing against water sprays without requiring complex multi-component sealing structures, thereby maintaining simplicity while achieving the protection function
Solution Approach 2:
The sealing function is merged with the cable clamp itself through the L-shaped design, where the vertical leg of the clamp acts as the sealing surface. This integration eliminates separate sealing components and simplifies the overall sealing structure while maintaining effectiveness against water ingress

AI summary
Protection box for electric connections comprising a first and a second half shell (1,2) which can be hooked to each other and overlapped onto each other so as to form a box shaped body with a seat for an electric block terminal or terminal junction box (M). The said protection box is internally provided with at least a cable clamp.
