Third, by configuring the electronic control circuit of the remote control switch so that electricity can be easily cut off and connected when needed without directly unplugging the multiple connection outlets,

And the amount of power consumed by the electrical appliances you can see, when not in use, there is no power loss wasted needlessly by an electric circuit without disconnecting the electrical outlet securely blocked an electric shock or fire danger meter and the remote control switch is not attached Multiple connection outlets are provided.

Description

Multi-connect outlet with power meter and remote control switch. {Omitted}

When using electrical appliances in homes or offices, plug the power cord into the outlet and connect the electricity. The consumer does not know the actual electric load capacity.The monthly electricity bill is unilaterally inspected by the meter reader by the integrated electricity meter installed by KEPCO. Due to the charge, users may bear unreasonable electricity charges when the instrument or electric line breaks down, and because there are always multiple power cords plugged into one outlet, unnecessary electricity is not needed even when not in use. Loss and risk of fire due to short circuit or overload.

In the conventional technology, power voltage and load current are sensed to measure the power consumption, and then converted into an appropriate signal through a current transformer or learning process, and then displayed as an appropriate signal.The power meter is bulky and expensive. Installed in switchboards or used by electricians for maintenance and repair.

Therefore, general consumers can not have a power meter, so the electricity bill is determined every month by a mechanical integrated power meter installed unilaterally by KEPCO, and the consumer, the user, uses the actual load capacity of his / her electronics. It was unknown and there were many difficulties compared to other products.

With the development of digital technology, electric and electronic parts are directly miniaturized, and precision measuring instruments that can directly check the voltage, current, and power of power supply are very small and can be purchased at low cost. Those who are interested can measure voltage, current and power.

In order to make it easy for consumers to know the power consumption, power supply voltage and load current of various electrical and electronic products used at home or office anywhere, the digital display is built in multiple connection outlets, and they are integrally combined to form a voltage sensor and It converts the signal of the current sensor into the amount of electricity and displays the Arabic numerals and the appropriate unit so that the user can always compare and check it.When not using the electrical appliance, the electricity can be safely operated by simple operation of the remote control switch without disconnecting the outlet directly. Configure to block.

Directly check the voltage, current and power supplied to the electric and electronic products used by the user, and cut off the electricity safely when not in use, so there is no unnecessary power loss on the line, and there is no risk of fire due to short circuit or overload Multiple connection outlets with power meters and remote control switches are provided.

The present invention is a multi-connected outlet equipped with a power meter and a remote control switch.With the multi-connected outlet plugged in to a power source, the remote control switch can conveniently and safely cut or connect a load. Power consumption of various electrical and electronic products connected through the connection outlet is displayed so that the electricity consumption can be known.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operating characteristics of the subject innovation.

1 is an actual perspective view showing the overall configuration of a multi-connected outlet with a power meter and a remote control switch and a remote control switch.

The power connection conductor and the electronic circuit board are firmly fixed to the groove of the case inside the case made of plastic injection molding, and the digital display 100 and the remote switch receiving sensor 101 indicating power consumption recognize information from the outside. The first power connection outlet 102 is protruding to connect the power from the other outlet, and the two connection load outlet 103 is plug-in to connect the home appliances.

2 shows the internal configuration and assembly state of the present invention,

3 is an electrical circuit diagram showing the principle of electrical operation.

If the power connection outlet 102 is plugged into another outlet, AC 220V power is always supplied to L1 and L2 on the input side, and the digital display 100 is displayed as 0000 W. When the load is not connected, the power is 0000. Connect the electrical and electronic products to the load connection outlet 103 to operate the device, and when the current flows, the current amount is sensed by the instrument CT CT 109, and the instrument transformer PT 108 detects the power supply voltage to It is supplied to the control CPU 106, the electronic control CPU 106 processes the signal received by the user via the remote signal generator 105 and the remote switch receiving sensor 101 of the signal selected by the user in the remote control switch box 101 Then, the selected information among the voltage, current, and power is supplied to the digital display 100 and instructed in numerical values and units.

Improved power connection outlet combines the functions of power meter and remote control switch to show power consumption.

When not using electrical appliances, the electric switch is safely disconnected without disconnecting the outlet, and there is no power loss, and there is no risk of fire due to a short circuit.

Consumers who use electricity, which is essential for modern civilization, can directly compare and check the power consumption of electric and electronic products to know the energy use efficiency, and they can cut off electricity conveniently when not in use. Multi-connected outlets with power meters and remote control switches are provided to reduce power loss and help save electrical energy.
