Abstract
A plug housing includes an ejector mechanism and a controller electrically coupled to the ejector mechanism for detaching electrical conductive blades of the plug from a mated connection with a female connector. In response to a switch signal from the controller, a solenoid is activated to release a latch in the mechanism, thereby permitting the force of a compressed spring to impel a structure outwardly from the plug. The controller may be located remotely from the plug and superimpose control signals to the plug over the power lines within the cord.
Claims5
An electrical device comprising:
- a plug housing comprising a plurality of conductive blades connected to respective wires of an electrical cord, and an ejector mechanism;
- and
- a controller connected to the cord, the controller electrically coupled to the ejector mechanism;
- wherein;
- the controller is located at a remote distance from the plug housing;
- and
- the ejector mechanism comprises:
- a shell circumferentially surrounding the conductive blades;
- a spring coaxial with the plug housing;
- and
- a latch, an end portion of the shell is positioned between the latch and the spring to maintain the shell within the plug housing, and
- wherein the shell comprises a plurality of individually spaced sections along the shell circumference, spaces between the sections exposing the conductive blades.
An electrical device as recited in 2, wherein the plug housing further includes a circuit board to which the blades are connected.
