Electrical Connector Insulated Rails Prevent Arcing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power plugs with exposed blades are prone to arcing and damage due to improper insertion, lacking sufficient protection against accidental disconnection and electrical failures.
Innovation Solution
The design incorporates elongate t-shaped rails and u-shaped receptor channels with an insulated central structure, providing a larger contact area and ensuring proper alignment, which reduces the risk of arcing and damage by isolating the connectors with an insulated mass between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional exposed blades are used in power plugs, then the device complexity is reduced and ease of manufacture is improved, but electrical reliability deteriorates due to arcing and damage from improper insertion
Solution Approach 1:
An insulated block is introduced as an intermediary structure between the conductive rails and the external environment. This insulated block serves as a mediator that prevents direct exposure of blades, eliminates arcing by isolating conductive elements, and guides proper insertion through recessed blade slots, thereby improving electrical reliability without requiring complex additional components
Solution Approach 2:
The patent employs an insulated housing structure that encloses the conductive rails and blades. This insulating shell provides protective enclosure, preventing accidental contact and arcing while maintaining the essential electrical connection function. The housing acts as a protective barrier that simplifies the overall design compared to multiple separate protective components
2Ease of operation
If fully exposed blades are used in power plugs, then the ease of operation is improved for quick connection, but safety deteriorates due to risk of arcing and damage
Solution Approach 1:
The insulated block with pre-formed blade slots and the recessed blade configuration perform preliminary protective action before connection occurs. The structure is designed in advance to guide proper insertion alignment, preventing improper contact and arcing before they can occur. The insulated housing is pre-configured to expose only necessary conductive elements in controlled positions
Solution Approach 2:
The insulated block serves as an intermediary that selectively exposes only the necessary conductive elements through controlled slots while maintaining isolation of other conductive parts. This mediator structure enables safe operation by preventing direct exposure of all blades, thereby reducing arcing risk while maintaining adequate ease of connection through the exposed slots
3Stability of the object's composition
If conventional straight-blade plugs are used, then the device complexity is minimized, but protection against accidental disconnection deteriorates
Solution Approach 1:
The patent employs a locking mechanism featuring cam surfaces with curved geometries that convert linear insertion motion into rotational locking action. The cam surfaces provide progressive engagement that guides the connector into proper alignment and secures it through mechanical interlocking, enhancing connection stability while maintaining relatively simple device structure through the use of continuous curved surfaces rather than multiple discrete components

AI summary
An electrical connector. The connector includes rails that attach to channels. The rails and the channels can be fully supported along their length to prevent damage. In addition, a nonconductive mass of the connector is positioned between the rails and the channels, preventing an accidental short.
