Electrical connector for use in Christmas tree
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Christmas tree illuminating devices pose electrical hazards due to exposed terminals and the risk of short circuits from small objects, making them unsafe for users, especially children.
Innovation Solution
An electrical connector with a hollow tube structure featuring concentrically arranged inner and outer securing rings, annular positive and negative terminals, and adapters, ensuring safe and rapid assembly and disassembly by separating terminals to prevent accidental contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors with exposed terminals are used, then electrical connection is achieved, but electrical hazard to users increases
Solution Approach 1:
The connector is divided into separate positive and negative terminal components, each housed in isolated compartments within the hollow tube structure. This segmentation prevents simultaneous contact with both terminals while maintaining functional electrical connection capability.
Solution Approach 2:
The terminals are nested within the hollow tube structure, with inner securing rings and outer securing rings creating concentric isolation layers. The positive terminal is positioned within the inner securing ring while the negative terminal is positioned between the inner and outer securing rings, providing physical nesting that prevents external contact.
2Ease of operation
If small objects are allowed in socket body, then assembly is simple, but short circuit risk increases
Solution Approach 1:
The socket body is segmented into isolated chambers for positive and negative terminals, preventing small objects from bridging both terminals. The concentric ring structure creates physical barriers that maintain simplicity while eliminating short circuit pathways.
3Productivity
If terminals are exposed for easy connection, then connection speed increases, but accidental contact risk increases
Solution Approach 1:
The terminals are nested within the hollow tube structure with concentric securing rings providing layered protection. This nesting allows rapid connection through the hollow tube interface while the nested structure prevents accidental contact with the embedded terminals during assembly and disassembly.

AI summary
An electrical connector for a Christmas tree includes a first electrical connector body, a second electrical connector body a first outer connector and a second outer connector. The first electrical connector body includes a first electrical connector body which includes an outer securing ring, an inner securing ring provided within the outer securing ring, a annular negative terminal, a annular positive terminal, a negative terminal adapter and a live terminal adapter. The second connector detachably is connected to the first connector, and includes a connecting base, a multiple ring member extending from the connecting base toward the first electrical connector body, a negative terminal, and a positive terminal. The first outer connector is connected to the first connector at a position opposite to the second connector. The second outer connector is connected to the second connector at a position opposite to the first connector.
