Switchboard Rail Mounting with Front-Only Wall Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting metal rails to the rear wall of electrical panel boxes are cumbersome, requiring access to the rear part during assembly, which is difficult with heavy boxes and inefficient in terms of execution time.
Innovation Solution
A device with an insulating body that allows direct connection of the rail to the mounting wall through the front face, using a blind hole for screw fixation and transverse arms for secure attachment, eliminating the need to turn parts during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection device requires access to the rear part of the box for assembly, then the rail can be securely connected to the mounting wall, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The patent inverts the traditional assembly sequence by enabling the rail to be connected to the mounting wall from the front side only. The connection device is designed so that the rail is inserted from the front and secured without requiring access to the rear of the box, thus resolving the contradiction between connection security and assembly convenience.
Solution Approach 2:
The connection device incorporates pre-configured elements such as the body with integrated fixing means and bearing surfaces that are already positioned to engage with the rail and mounting wall. This preliminary arrangement allows the connection to be completed from the front without requiring subsequent rear access for securing.
2Stability of the object's composition
If the box is heavy, then it provides structural stability, but turning the box during assembly becomes difficult and time-consuming
Solution Approach 1:
The patent inverts the traditional assembly approach by eliminating the need to turn or reposition heavy boxes during assembly. The connection device is designed to perform all securing operations from the front side, so the box remains stationary throughout the assembly process, saving time and effort.
3Strength
If the connection device uses threaded metal inserts requiring screws from both front and rear, then the rail connection is secure, but the assembly process is complex
Solution Approach 1:
The patent merges the fixing means into a single integrated body that performs all securing functions from the front side. The body incorporates the threaded metal insert and bearing surfaces in one unified structure, eliminating the need for separate rear access and multiple screwing operations, thus reducing assembly complexity while maintaining connection strength.

AI summary
A device (1) for connecting a rail to the wall of an electrical panel enclosure, having a body made of electrically insulating material that includes a head (10) for fastening means, a central portion (20) having a bearing surface (21) for the rail, a base portion (30) including a bearing surface (31), a coupling portion (33), and coupling means (35). The body is moved between a position where the bearing surface rests against the front surface of the wall, the coupling portion is inserted into a seat in the wall, and the coupling means pass through the seat, and a position where the coupling portion is rotated within the seat and the coupling means face the rear surface of the wall.
