Solution Overview
Problem
Existing box-like protections for electrical connections are complex and time-consuming to use, and they do not provide adequate cable locking mechanisms.
Innovation Solution
A box-like protection system comprising two half-shells with internal clamping mechanisms that securely lock cables at four points using flexible arms and fixed abutments, facilitating quick assembly and enhanced cable retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional box-like protections are used, then cable locking is provided, but assembly is complex and time-consuming
Solution Approach 1:
The box-like protection is divided into two separate half-shells that can be independently manufactured and then assembled together. This segmentation allows for simpler manufacturing of each half-shell and enables parallel assembly operations, reducing overall assembly time and complexity while maintaining the protective enclosure function.
2Reliability
If traditional box-like protections are used, then electrical connection protection is provided, but cable locking is inadequate
Solution Approach 1:
The cable locking function is merged with the half-shells themselves through integrated clamping elements and sealing lips that are formed as part of the half-shell structure. This integration eliminates the need for separate locking mechanisms, providing reliable cable retention while reducing overall device complexity.
Solution Approach 2:
The half-shells incorporate localized clamping elements and sealing lips at specific positions where cables need to be secured. These localized features provide targeted cable locking and sealing where needed, rather than requiring a complex overall locking mechanism for the entire enclosure.
3Productivity
If multiple box-like protections are installed rapidly, then installation efficiency is improved, but adequate cable locking becomes difficult to maintain
Solution Approach 1:
The clamping elements and sealing lips are pre-formed as integral parts of the half-shells during manufacturing. This preliminary action ensures that the cable locking capability is already prepared and configured before installation, allowing for rapid installation while maintaining reliable cable retention without requiring complex assembly steps.

AI summary
Box-like protection for electrical connections, including two half-shells that, in cooperation with each other, define an internal seat for a terminal block or similar device for making electrical connections, and at least one opening for the entry/exit of electric cables connectable to the terminal block, and including an internal cables-locking mechanism. The internal cables-locking mechanism is a clamping mechanism including elements formed, inside each half-shell, on opposite sides with respect to the at least one opening, wherein a clamping element has a movable body and the other clamping element has a fixed body such that, in correspondence of the at least one opening, there are two movable clamping bodies and two fixed clamping bodies adapted to clamp a respective cable on four clamping points.
