Abstract
The ejecting electrical outlet has magnets positioned within the electrical receptacle. Springs are positioned between the magnets and are compressed when the prongs of a plug are entered into the outlet. The strength of a magnetic field generated by an overload electric current is sufficient to defeat the attractive forces between the magnet and to permit decompression of the spring and ejection of the plug from the electrical outlet.
Claims1
An ejecting electrical outlet comprising:
- an electrical receptacle box with apertures permitting the passage of prongs of an electrical plug and being connected to powerlines;
- a first set of magnets positioned within said electrical receptacle and electrically connected to said powerlines;
- a second set of magnets being disposed within said electrical receptacle and being displaceable from a position in juxtaposition to said apertures of said electrical receptacle to a position in close juxtaposition to said first set of magnets;
- and
- a biasing means between said first and second magnets;
- wherein entry of said prongs of said electric plug into said apertures slots of said electrical receptacle causes said second set of magnets to be displaced towards said first set of magnets, and said first and second magnets having sufficient attractive forces to hold said prongs of said plug within said electrical receptacle;
- and
- wherein the strength of a magnetic field generated by an overload electric current in said powerlines is sufficient to defeat the attractive forces between said first and second magnets and to permit displacement of said second set of magnets toward said openings of said electrical receptacle.
