Tool-Free Current Distribution Device Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing current distribution devices in electrical boxes require the use of fixing screws, which complicates the installation process and may not ensure a secure locking mechanism without tools.
Innovation Solution
A sliding assembly system with retaining elements and studs allows for tool-free installation and positioning of the current distribution device within an electrical box, utilizing an L-shaped movement to securely lock the device in place along the uprights of the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing screws are used to secure the current distribution device, then the device can be firmly fixed to the electrical box, but the installation process becomes complicated and requires tools
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a snap-fit mechanism. The support elements feature retaining elements that engage with corresponding engagement elements on the distribution device, allowing tool-free installation while maintaining secure fixation. This substitution eliminates the need for tools and simplifies the installation process while ensuring reliable mounting.
Solution Approach 2:
The support elements are designed to be self-aligning and self-locking. The retaining elements automatically engage with the engagement elements when the distribution device is inserted, providing self-service installation without requiring external tools or complex alignment procedures. The mechanism itself performs the fixing function through its inherent geometric design.
2Ease of operation
If a tool-free installation system is used, then the installation process is simplified, but the locking mechanism may not be secure enough
Solution Approach 1:
The retaining elements and engagement elements are designed with asymmetric geometries that provide directional engagement. The retaining elements have specific shapes that match corresponding features on the distribution device, creating a secure interlocking mechanism that prevents disengagement during normal operation while allowing easy insertion during installation.
Solution Approach 2:
The engagement interface incorporates curved surfaces and rounded features that facilitate smooth insertion while providing robust mechanical interlocking. The curved geometry of the retaining elements and engagement elements allows for self-alignment during insertion and creates a secure fit that resists拔出 forces during operation.

AI summary
The present invention relates to a device for maintaining and positioning a current distribution device D in an electrical cabinet, said device being intended to supply rows of electrical equipment mounted on a mounting support in the cabinet, said device comprising, housed in an insulating box, a bar intended to carry the neutral and at least one bar intended to carry a phase, said bars being arranged substantially parallel to each other, and substantially perpendicular to the longitudinal direction of the mounting supports, each bar supporting elements for connection to a cable or the like.This device is characterized in that it includes sliding means provided partly on the distribution device D and partly on at least one support element (9,10) attached to the chassis of the box, these means allowing the device D to slide relative to the support element(s) (9,10) in two successive movements forming an L, the second movement ending with the passage of a hard point ensuring the locking of the device relative to the box.
