Rapid Wire Junction Assembly for Precise Waterproof Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rapid wiring devices lack precise and stable fixing technologies for wires, leading to misalignment and deformation issues, and their waterproof structures are inefficient due to jelly glue overflow and misaligned threads.
Innovation Solution
A rapid wiring device with a limiting groove and position-limiting portions in the junction box, combined with a wire box and tightening cover that accurately aligns and secures conductors with a second electric wire, using a waterproof film for sealing and preventing water intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional wiring methods are used without precise fixing technology, then the wiring process is simple, but the wire alignment and connection precision deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-setting the limiting groove and position-limiting portions in the junction box before wire insertion. These pre-configured structures automatically guide and position the wires correctly as they are inserted, eliminating the need for complex post-insertion alignment procedures while ensuring precise wire positioning and connection accuracy.
2Reliability
If the lock cover is forcibly locked to correct wire misalignment, then the wire connection may be secured, but the copper thorn becomes skewed and deformed
Solution Approach 1:
The patent applies preliminary anti-action by designing the position-limiting portions to prevent wire misalignment before the locking process begins. The limiting groove and position-limiting structures constrain the wire positions in advance, ensuring that when the lock cover is closed, the copper thorns align correctly with the wire cores without requiring forced locking, thus preventing skew and deformation of the copper thorns.
3Reliability
If the locking stroke is increased to ensure jelly glue overflow for sealing, then waterproofing improves, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent applies the taking out principle by removing the complex multi-component waterproof structure (jelly glue, upper floating plate, lock cover locking mechanism) and replacing it with a simplified waterproof film that directly lines the limiting groove. This extracted solution achieves effective waterproofing through the waterproof film's inherent properties without requiring complex assembly or excessive locking strokes, thereby reducing device complexity while maintaining waterproof reliability.
4Adaptability or versatility
If the threaded part is divided into two pieces with incomplete threads, then assembly flexibility increases, but the lock cover easily becomes misaligned and crooked
Solution Approach 1:
The patent applies the merging principle by integrating the positioning and locking functions into a unified structure. The position-limiting portions are combined with the limiting groove to form an integrated positioning system that ensures precise alignment throughout the assembly process. This merged structure eliminates the misalignment issues caused by divided threaded parts while maintaining assembly flexibility through the modular junction box design.

AI summary
A rapid wiring device includes a junction box provided with a limiting groove of which the bottom surface is provided with the tip portions of two conductors. A wire box fixing a second electric wire is set in the limiting groove, then it is combined on the junction box through a tightening cover, which is used to push the wire box to move towards the bottom of the limiting groove, so that the tip portions of the two conductors pass through the wire box and penetrate the insulating layer of the second electric wire to touch the core wire of the second electric wire, so that the first electric wire and the second electric wire are quickly connected.
