Junction Box Structure With Detachable Cover for Wiring Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current junction boxes for panel lights lack sufficient structural stability, making them prone to damage from external forces, and they often fail to provide adequate space for electric wires, leading to increased costs and installation difficulties.
Innovation Solution
A high structural stability junction box design featuring a first side wall with a locking edge and inclined edge, a second side wall with corresponding locking and inclined edges, and a third side wall with fixing grooves, allowing for secure attachment of a junction box cover with extended covers for enhanced stability and space accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the junction box uses a compact integrated design with the power supply box, then the overall device size is reduced, but the space for accommodating electric wires becomes insufficient
Solution Approach 1:
The junction box is divided into a box body and a detachable cover, allowing the internal space to be optimized for wire accommodation while maintaining a compact external footprint. The cover can be removed to access the wiring compartment, effectively separating the wiring function from the power supply compartment.
2Quantity of substance
If an external junction box is mounted behind the panel light, then sufficient space for wiring is provided, but the installation becomes difficult and cost increases
Solution Approach 1:
The junction box is integrated into the power supply box structure, combining two previously separate components into one unified device. This merger provides sufficient wiring space within the integrated body while simplifying installation to a single unit, reducing both manufacturing complexity and installation difficulty.
3Ease of manufacture
If the junction box uses a simple structure, then manufacturing cost is reduced, but structural strength becomes insufficient and the box is prone to damage from external forces
Solution Approach 1:
The junction box employs a composite structure combining a rigid box body with a reinforcing rib system. The ribs are integrally formed with the box body, creating a composite structural system that enhances strength and impact resistance without requiring additional materials or complex manufacturing processes.
4Ease of manufacture
If the junction box uses a simple structure, then manufacturing is simplified, but reliability under external forces becomes insufficient
Solution Approach 1:
The box body is segmented into multiple sections with reinforcing ribs distributed throughout the structure. This segmentation approach distributes external forces across multiple reinforcement points, enhancing overall reliability without requiring a completely complex structural design.
Solution Approach 2:
The integral rib structure creates a composite system where the rib and box body work together to resist external forces, improving reliability while maintaining manufacturing simplicity through integral forming.

AI summary
A high structural stability junction box includes a first side wall, a second side wall, a third side wall, a top surface and a junction box cover. The first side wall has a first locking edge and a first inclined edge. The second side wall is opposite to the first side wall, and has a second locking edge and a second inclined edge. The third side wall is disposed between the first side wall and the second side wall. The top surface has four side edges and a wiring hole. The first side wall, the second side wall, and the third side wall respectively extend from three of the four side edges, and the wiring hole extends from the top surface to the third side wall. The junction box cover has a L-shaped cross-section and is detachably mounted on the wiring hole.
