Abstract
A release mechanism for an electrical plug, and a method of releasing the plug from a socket. The release mechanism includes a perimeter ejecting member which substantially surrounds the electrical contact prongs of the plug and is moveable with respect thereto. A remote switch is energized, which activates the release mechanism and disengages the plug from the socket by sliding over the contact prongs.
Claims7
A releasable electric plug, comprising
- a. electrical contact means for providing electrical connection to an electrical energy source;
- b. housing means comprising an outer housing member and an inner housing member, said outer housing member being slidable with respect to said inner housing member from a first electrical energy source-engaging position to a second electrical energy source-disengaging position, said outer housing member substantially surrounding said electrical contact means in said second electrical energy source-disengaging position;
- c. activation means for causing said outer housing member to move from said first position to said second position.
A method of remotely disengaging an electric plug from an electrical receptacle, said electric plug comprising:
- electrical contact means for providing electrical connection to an electrical energy source;
- housing means comprising an outer housing member and an inner housing member, said outer housing member being slidable with respect to said inner housing member from a first electrical energy source-engaging position to a second electrical energy source-disengaging position, said outer housing member substantially surrounding said electrical contact means in second electrical energy source-disengaging position;
- activation means for causing said outer housing member to move from said first position to said second position, said activation means comprises a solenoid having a moveable plunger, said inner housing member comprising a recess through which said plunger extends when said plug is in said first position, and an inner housing gutter, and said outer housing member comprising an outer housing gutter into which said plunger extends when said plug is in said first position, and an inner notch slidingly received by said inner housing gutter;
- said method comprising:
- activating said activation means such that said plunger is withdrawn from said outer housing gutter causing said outer housing to move from said first position to said second position and thereby disengaging said electric plug from said electrical receptacle.
