Nested Insulated Electrical Connector for Safe Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connector systems for electrical components, such as bushings and plugs, pose safety risks when separating energized components, as the extended conductors can cause short circuits or flashovers if not handled properly.
Innovation Solution
A connector system where the conductor does not extend beyond the molded insulation, allowing safe separation using an insulated hot stick, with a threaded stud or stud receiving cavity for secure connection, eliminating exposure risks during energized conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conductor extends beyond the molded insulation to facilitate connection, then the ease of operation is improved, but the safety risk increases due to potential short circuits and flashovers during separation
Solution Approach 1:
The conductor is nested within the molded insulation housing, with the conductor end positioned inside the insulating cap or elbow rather than extending outward. This nesting configuration allows the conductor to remain accessible for connection while being protected by the insulating structure, eliminating exposure to ground contact during separation operations
Solution Approach 2:
The molded insulation acts as an intermediary barrier between the exposed conductor and the external environment. By positioning the conductor end within the insulating cap or elbow, the insulation material mediates the interaction, preventing direct contact between the energized conductor and ground while still allowing electrical connection to be made
2Object-affected harmful factors
If the conductor is enclosed within the molded insulation, then the safety is improved, but the ease of operation deteriorates due to difficulty in making connections
Solution Approach 1:
The connector system is segmented into distinct functional zones: the molded insulation housing providing safety, the insulating cap or elbow providing protective enclosure, and the conductor end providing electrical connection. This segmentation allows each component to fulfill its specific function - the conductor remains enclosed for safety while its end is positioned to facilitate connection through the insulating structure
3Adaptability or versatility
If the conductor extends beyond the insulation, then the adaptability is improved for various connection configurations, but the reliability deteriorates due to risk of short circuit and flashover
Solution Approach 1:
The insulating cap or elbow serves multiple functions: it provides electrical insulation, protects the conductor end, and facilitates connection to various mating components. This multi-functionality allows the system to achieve adaptability for different connection configurations while maintaining reliability through the protective insulating enclosure that prevents short circuits and flashovers
