Abstract

This invention uses the phase checking green light emitting diode (2) in the single-phase two-wire 220 volt AC power supply plug (1) that we currently use to check the alternating current phase in the built-in electronic equipment to extend the lifespan of electronic products and the stability of the product. The purpose is to prevent electric shock and fire prevention in advance.

The current 220V AC power plug does not have this phase check function, so users do not know it and use the power supply, which causes economic cost due to defective electronic equipment and various other losses.

How to use is to insert the single-phase 2-wire 220 (V) AC power plug (1) into the outlet and push the pushbutton switch (3) to turn on the green light emitting diode (2). When the pushbutton switch (3) is pressed after the single-phase 2-wire 220 (V) AC power plug (1) is plugged into an outlet, the green light emitting diode (2) is turned off. This can be checked with the naked eye, so that it is possible to use the correct electricity, and it is designed for convenience.

Description

AC Power Phase Confirmation Green Light Emitting Diode Built-in Power Plug {Electricity Plug of AC Phase Confirmation GREEN LED insertion Type.}

The present invention provides a green light emitting diode (2), a resistor 120Kohm / 1W (4), and a pushbutton switch between the voltage terminal (5) and the ground terminal (6) so that the phase of the single-phase two-wire 220 (V) AC power source can be used. Connect (3). The operating state is that the green light-emitting diode (2) lights up when the switch is turned on (pressing). The AC power plug (1) is normally plugged into an outlet. The green light-emitting diode (2) flashes when the AC power plug (1) is plugged into an outlet and the pushbutton switch (3) is turned on. It is designed to prolong electrical life, equipment life and prevent fire and electric shock by checking and using. The 220V AC power plug currently in use is designed so that the power phase cannot be identified by the user, so the user does not see the phase and uses electricity.

Therefore, the present invention is designed so that the green light emitting diode (2) is built in the single-phase two-wire 220 (V) AC power plug (1) used in daily life so that the correct electricity can be used by immediately checking the phase.

The present invention incorporates the phase check green light emitting diode (2) into the single-phase 2-wire 220 volt (V) AC power plug (1) that we currently use to verify the AC phase and extend the life of all electronic products. It aims to improve stability and prevent electric shock and fire prevention. The current 220V AC power plug does not have this phase check function, so users do not know it and use the power without it.

In addition to the current single-phase two-wire 220 (V) AC power plug (1), a resistor 120Kohm, 1 Watt (4), green light emitting diode (2), and pushbutton switch between the voltage source terminal (5) and the ground terminal (6) 3) is configured as in the circuit of FIG.

When using computers, electronics, and heating equipment used for single-phase 2-wire AC power supply 220 (V), it is possible to reduce economic losses due to failure prevention, life extension, electric shock, and fire protection of equipment by knowing and using the power phase. It can prevent human life.

In other words, when the user plugs the power plug into the outlet, the user immediately checks the lighting and blinking relationship of the green light emitting diode (2) with the naked eye so that the user can easily use the electronic equipment, the computer and the heating equipment.

In addition, the green light emitting diode (2) is not attached to the electronic device, but is attached to the single-phase 2-wire 220 (V) AC power plug (1). And convenience together.

Claims (1)

In using the single-phase 2-wire 220 (V) AC power supply, the green light emitting diode (2) and the resistor 120Kohm between the voltage source terminal (5) and the ground terminal (6) of the present invention in order to use electricity after confirming the correct power phase. The / 1W (4) and pushbutton switch (3) are configured like a circuit to check the phase when using electricity. Therefore, it claims the single-phase two-wire 220 (V) AC power supply plug (1) with a circuit for checking the power phase.
