This innovation introduces flat electrical plug prongs that are straight but initially inclined toward each other. During insertion, the outlet contacts separate the prongs until they become parallel. Once fully inserted, their elastic recovery generates a controlled preload that maintains stable electrical contact, compensates manufacturing tolerances and outlet wear, and improves connection reliability while reducing contact resistance and overheating.
Flexible Flat Electrical Plug Prongs with Elastic Preload for Improved Electrical Contact
The invention relates to an electrical plug incorporating flat conductive prongs that are initially manufactured with a slight inward inclination toward each other while remaining straight along their entire length.
During insertion into a standard electrical outlet, the outlet contacts progressively force the prongs apart until they reach a substantially parallel position. This controlled elastic deformation stores mechanical energy in the prongs.
Once the plug is fully inserted, each prong naturally tends to recover its original inclined position. This elastic recovery generates a controlled preload that maintains stable contact pressure between the prongs and the outlet contacts throughout operation.
The system automatically compensates for manufacturing tolerances of both plugs and outlets, as well as wear occurring during long-term service. The result is a more reliable electrical connection with lower contact resistance and reduced heat generation.
Main advantages
• Increased electrical contact reliability.
• Automatic compensation for manufacturing tolerances.
• Compensation for outlet wear throughout service life.
• Reduced contact resistance and overheating.
• Improved mechanical stability after insertion.
• Passive system requiring no additional springs or moving components.
The technology can be incorporated into conventional flat electrical plugs while maintaining compatibility with existing outlet standards, making it suitable for consumer, commercial and industrial electrical applications.
