Abstract

A fused electrical receptacle is particularly designed for use with an electrical waterbed heater. A housing includes a power cord extending therefrom for connection to a conventional AC outlet. A fuse is connected in line within the housing for providing circuit protection which prevents a shorted waterbed heater from damaging electrical circuits in a house and creating a potential fire hazard. An indicator is preferably provided within the housing for indicating when the fuse is blown. A solenoid coil may be connected to the power cord on a downstream side of the fuse and has an extensible rod disposed in a retracted position when the solenoid coil is energized and spring biased to an extended position when power supply to the solenoid coil is interrupted. A pivotal flag has a distal visual signal portion movable through an aperture in the housing between raised and lowered positions. A spring biases the flag to a lowered position and an actuating arm on the flag is disposed adjacent the solenoid coil rod for raising the flag upon failure of the fuse. An additional power indicating LED may be provided.

Claims

1. A fused electrical receptacle, comprising:

a housing;

a power cord extending from said housing for connection to a conventional AC outlet;

said power cord extending to an electrical socket on said housing for connection of an electrical appliance to said socket;

a fuse within said housing connected to said power cord; and

a pop up flag for indicating when said fuse is blown.

2. The fused electrical receptacle of claim 1, wherein said flag is actuated by extension of a solenoid rod upon failure of said fuse.

3. The fused electrical receptacle of claim 1, further comprising a power indicating light operably connected to said power cord via said fuse.

4. A fused electrical receptacle, comprising:

a housing;

a power cord extending from said housing for connection to a conventional AC outlet;

said power cord extending through said housing and terminating at an electrical socket for connection to an electrical appliance;

a fuse within said housing connected to said power cord;

a solenoid coil connected to said power cord via said fuse;

said solenoid including an extensible rod disposed in a retracted position when said solenoid coil is energized and spring biased to an extended position when power supply to said solenoid coil is interrupted by failure of said fuse;

a pivotal flag having a distal visual signal portion movable through an aperture in said housing between raised and lowered positions;

a spring biasing said flag to said lowered position; and

an actuating arm on said flag disposed adjacent said solenoid rod for raising said flag upon failure of said fuse.

5. The fused electrical receptacle of claim 4, further comprising a power indicating LED connected to said fuse via said power cord.
