Abstract
By using fundamental principals of electricity "The Power Indicating Plug, Cord, Switch or Receptacle" provides an indication to the user that current is flowing to the device plugged in or switched on. This invention can be used with any number of voltages and current loads. One example of an immediate use is to insert the new device between the source of 115Vac power and the block heater of a vehicle, thus giving clear indication on a cold winter day that the block heater is in fact operating.
Description
2 ~ 82~2~
Spec;fic~tion When an electrical device is re~uired to be operating and fails it is often not discovered until after the fact and many times with costly conse~uences or with much discomfort or inconvenience. A
broken wire, Open circuit (Open Fuse or Breaker), or defective electrical device can all be detected immediately when using the "Power Indicating Plug or Receptacle."
This device for which the Patent Application has been submitted is to be manufactured in several different ways; this depends on use, voltages used, and current re~uired. The principal electrical design will remain the same but the end products will vary.
The main principal by which the Power Indicator (Stated in Claims 1 and 2, and shown on Drawing Sht. 1) Works is as follows:
- The Hot Wire or Wires supplying power to an electrlcal load or device is be passed through or wound onto a core.
- A small diameter wire (ex. AWG 30)will be wound on the same core.
- A Light Emitting Diode will be connected to each end of the small diameter wire.
- Zener Diodes or other components may or may not be used depending on whether voltage clamping is required as per application of t~e device.
By induction, when current passes through the hot wire to the electrical device which a person desires to use, a low voltage is produced on the small diameter wire which causes the LED to emit light. Since the indication parts of this product are electrically isolated from any line power sources this device is safe and extremely useful.
The following descriptions show the "power indicator~' as an insertion unit, a switched unit, a receptacle, and an extension cord.
a. Power Indicating Insertion Receptacle.
(Stated in Claim 3 and shown on Drawing Sht. 5) - This Power Indicating Insertion Receptacle would plug into an extension cord or or standard Outlet (Voltage could vary ex.
European or North American). An electrical device or an extension cord would then plug into the Power Indicating Receptical. When sufficient current flows through the hot wire(s) of the receptacle the LED would emit light. The number of outlets available on the Power Indicating Receptacle would be one or more, depending on the users application. The Power Indicating Receptacle may or may not have a seperate indicator for each outlet, depending on the users application.
b. Power Indicating Receptacle.
(Stated in Claim 4 and shown on Drawing Sht. 2) - The Power Indicating Receptacle would be similar to any standard outlet with the addition of the low voltage indicating components. The Receptacle would be able to be panel mounted or placed in a standard electrical box. When an electrical device is plugged into the Receptacle and there is sufficient current flow the LED would emit light.
c. Power indicating Switch (Stated in Claim 5 and shown on 3rawing Sht. 3) - The Power Indicating Switch would be similar to any standard electrical switch with the addition of the low voltage indicating components. The Switch would be able to be panel mounted or placed in a standard electrical box. When an electrical device is wired to the switch and the switch is turned on and there is sufficient current flow the LED would emit light.

d. Power Indicating Extension Cord (Stated in Claim 6 and shown on Drawing Sht. 4) - This Power Indicating Extension Cord would be similar to standard extension cords being produced with the addition of the low voltage indicating components. The Power Indicating Extension cord would plug into a standard Outlet (Voltage could vary ex.
European or North American). An electrical device would then plug into the Power Indicating Extension Cord. When sufficient current flows through the hot wire(s) of the receptacle the LED would emit light. The number of outlets available on the Power Indicating Extension Cord would be one or more, depending on the users application. The Power Indicating Receptacle may or may not have a seperate indicator for each outlet, depending on the users application. Please be aware that the indicating portion of the circuit could be on the male end the cable, (ie. the plug) if that option were ordered.
e. Power Indicating Block Heater Cord (Stated in Claim 7 and shown on Drawing Sht. 6) - A power indicating block heater cord is also to be produced with the Power Indication circuit being on the male end of the cord and the female end plugging into the block heater.
