Tamper resistant power receptacle

A tamper resistant power receptacle moveable between an unpowered state to a powered state for supplying power to a plug having a pair of plug blades, said tamper resistant power receptacle comprising:

• a body having a sidewall defining at least one body cavity and having at least one short ramp extending from said sidewall into said cavity;
• a first and second power bus adapted for selectively receiving and supplying power to said plug while in the powered state;
• a moveable socket having at least a first and second slot configured for receiving a pair of tine receivers extending through said sliding socket, each of said tine receivers being adapted for receiving one of the plug blades;
• said tine receivers being compressible by said short ramp as said moveable socket travels between an upper position to a lower position;
• and
• said upper position being associated with an unpowered state and said lower position being associated with a powered state, whereby said plug is in electrical communication with said power supply in said powered state.

An tamper resistant rotational power receptacle rotatable between an unpowered state to a powered state for supplying power to a plug having a pair of plug blades, said tamper resistant power receptacle comprising:

• A body having a circular sidewall and a body recess receiving a rotatable socket adapted for receipt of the plug blades of said plug;
• said rotatable socket extending upwardly from a power connector to said central socket base and presenting a socket base recess;
• said socket base recess adapted for receiving a pair of blade contacts each having a proximal and distal end, said proximal end extending upwardly towards said central socket base, said distal end spaced opposite from and extending from said socket base recess for reciprocal engagement with said power connector in the powered state;
• a first and second power busses, each having a pair of power connectors adapted for receipt of each of said distal ends;
• a locking spring which extends from said proximal end to said distal end, said locking spring being adapted for securing a received plug blade during rotation of said rotatable socket from the unpowered state;
• said first and second power bus selectively receiving said distal end and supplying power to said plug while in the powered state;
• and
• said plug being operatively disconnected from said first and second power buses in said unpowered state.

A movement lock comprising;

• A body having one or more shaped cavities and one or more receivers;
• An object shaped to closely fit the body cavity, movable within said cavity, and having a shaped “key” slot;
• One or more resilient locking members within the object, wherein at least one end of a resilient member protrudes from an outlet in the object to engage a receiver in the body;
• The locking members are configured to deform in a manner that retracts the ends into the object when a “key” with the proper shape or size characteristic is inserted.

A rotary switched receptacle suitable for extension cords comprising:

• a bottom cap with wire entry, attachment openings, and two tubular projections, each containing a spring biased spring plunger;
• a metal frame with ground terminal, openings to pass the spring plungers there through, and threaded openings to attach the bottom cap and top cap-socket assembly combination;
• a body with a ground contact, two power busses with wire attachment means and switch receivers, openings for the spring plungers, circular cavity for a socket assembly, and means to unlock a tine lock for removal of the plug;
• a socket assembly having a central opening for fastening to the metal frame, slots for the insertion of a plug, openings to allow the pins of the spring plunger to intrude into the blade slots, pivotally mounted upwardly biased locking bar ends configured to press the plug power blades against “L” shaped blade contacts and have a jamming effect to prevent removal, and a means to maintain a fixed geometrical relationship with the top cap;
• and
• a top cap with the usual slots for insertion of a plug.
