Flush-Mounted Junction Box With Flip Cover for Easier Line Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Junction boxes mounted on walls have limited internal space when a socket or switch is directly installed, making them difficult to repair and maintain due to lack of space for threading and disordered cable management.
Innovation Solution
A flush-mounted junction box design featuring a junction box body with a step surface and a flip cover body, integrated wire clamping plates, and a fastener system that allows for easy separation of the flip cover without removing the switch or socket, providing a large internal space for threading and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a socket or switch is directly mounted on the junction box, then the mounting appearance is sleek and flush with the wall surface, but the internal space becomes insufficient for cable management and repair
Solution Approach 1:
The junction box is divided into two functional zones: a front mounting portion that interfaces with the wall surface for aesthetic flush mounting, and a rear extended portion that provides additional internal volume for cable management. This segmentation allows the box to maintain a sleek appearance while solving the space constraint problem.
2Volume of moving object
If the junction box internal space is increased, then cable management space is sufficient, but the flush mounting appearance cannot be maintained
Solution Approach 1:
Instead of increasing volume uniformly in all directions, the extension is directed specifically toward the rear of the junction box, perpendicular to the wall mounting surface. This dimensional approach allows the front face to remain compact for flush mounting while the rear extends to provide necessary internal space.
3Ease of repair
If the switch or socket is removed for repair, then the interior can be accessed, but the repair process becomes complicated
Solution Approach 1:
The front cover is designed as a separable component that can be removed independently from the main junction box body and the mounted electrical devices. This extraction principle allows access to the interior for cable repairs without requiring removal of the switch or socket, simplifying the repair process significantly.
4Ease of operation
If the junction box is designed with sufficient internal space, then cable threading is easier, but the wall mounting space requirement increases
Solution Approach 1:
The junction box employs local quality by providing extended internal volume specifically in the rear region where cable management is needed, while keeping the front mounting portion compact. This localized space allocation optimizes cable threading ease without increasing the overall wall footprint.

AI summary
The present disclosure discloses a junction box mounted to be flush with a wall surface and convenient for line repair, and belongs to the technical field of junction boxes. The junction box includes a junction box body and a flip cover body. A top surface of one part of the junction box body sinks to form a step surface; the step surface extends to an edge of the junction box body; the flip cover body is hinged to a first end of the junction box body; the flip cover body is clamped on the junction box body; and the flip cover body is fitted to the step surface and presses against a second end of the junction box body.
