Abstract
The utility model provides a prompt socket capable of automatically identifying power supply phase positions, which comprises a luminescent device, a sound prompting device, and a protector, wherein, the luminescent device comprises a left red-green LED and a right red-green LED; the red end of the left red-green LED is connected with a neutral wire, whereas, the green end is connected with a live wire; the red end of the right red-green LED is connected with the live wire, whereas, the green end is connected with the neutral wire; and one end of the sound prompting device is connected with the neutral wire, and the other end is connected with the earth wire. The prompt socket can play the role of sound and light alarm, and is suitable for house, office space and other construction sites.
Description
Technical field
The invention belongs to technical field of electronic devices, the particularly a kind of electronic device that can discern the power supply phase place automatically.
Background technology
In daily life, generally use single phase poaer supply, be also referred to as power for illumination.Two wires in the lighting circuit, one write a Chinese character in simplified form L (LIVE WIRE) by to be made live wire, English, and it is yellow or green to be generally redness; Another root then is zero line, and N (NEUTRAL WIRE) write a Chinese character in simplified form in English, is generally blueness or yellow; Also have ground wire E (EARTH WIRE) in addition, be generally yellow green or black.
The difference of live wire and zero line is that their voltage over the ground is different: the voltage to earth of live wire equals 220V; The voltage over the ground of zero line equal zero (itself with the earth be connected together).So run into live wire when people's a part, another part stands on the ground, the voltage between two parts of this of people equals 220V, just the danger of electric shock has been arranged.Otherwise the people promptly uses hand to remove to grab zero line, if the people stands on the ground, because the voltage over the ground of zero line equals zero, so the voltage between people's the health each several part equals zero, the people does not just have the danger of electric shock.
In the domestic circuit socket, general according to the international regular mode of connection, that is: a left side zero right fire upward carries out wiring.Because zero line itself is a ground connection, and the electrician feels the repetition wiring when earth connection, in order to save the trouble of redundant wiring, seldom sees in the domestic circuit and inserted ground wire.
But, at this moment may cause very big influence to circuit because a variety of causes possibly produce zero line and live wire and connect anti-situation.If this type of situation takes place, confirm reason like need, generally can utilize methods such as voltage test pencil test by manual work, detect the power phase relation.The instrument that this type of action need is other, and after destroying, just can test, therefore connect anti-situation prompting inadequately automatically, in time for phase place.
The utility model content
In order to realize automatically identification power supply phase place, and carry out acousto-optic and remind, the utility model provides a kind of can discern power supply phase place prompting socket automatically.
Automatically identification power supply phase place prompting socket comprises luminescent device, auditory tone cues device and protection device; Wherein luminescent device comprises two red and green luminous diodes about two; Wherein " red end " of the red and green luminous diode in the left side is connected with zero line; " green end " is connected with live wire, and " red end " of the red and green luminous diode in the right is connected with live wire, and " green end " is connected with zero line; One end of auditory tone cues device is connected with zero line, and the other end is connected with ground wire.
The application's advantage is that its circuit is simple, and prompting is timely, and safe, and easy-to-use ability is strong.
Description of drawings
Fig. 1 is the application's a circuit structure diagram.
Wherein VD1 and VD2 are diode, and VD3 is left red and green color light-emitting diode, and VD4 is right red and green color light-emitting diode.
F is a buzzer.
Embodiment
In this specific embodiment, can adopt red and green color light-emitting diode and buzzer as light, sound suggestion device.Be in the present embodiment on the basis of wall jack or wiring board, add resistance, diode, light-emitting diode, buzzer and several kinds of electronic devices of piezo-resistance, and it is installed in wall jack or wiring board inside.
Referring to Fig. 1, under normal circumstances, after live wire and zero line access power supply; In accordance with international practices, all electrical equipment should be a left side zero right fiery principle basically, and the light-emitting diode in left side sends green glow; The light-emitting diode on right side sends ruddiness, and the promptly left green right side is red, and; Because an end of buzzer is a zero line, the other end is a ground wire, so can not send chimes of doom.Therefore, under normal circumstances, suggestion device should be " the left green right side is red ", and buzzer is quiet.
But after live wire and zero line were exchanged (right zero left side fire), opposite with normal condition, the light-emitting diode in left side sent ruddiness, and the light-emitting diode on right side sends green glow, and the promptly left red right side is green.In addition, because an end of buzzer is a live wire, the other end is a ground wire, so also can send chimes of doom.Thus, this circuit can play the sound and light alarm effect, can application and family, office space and job site, and hear and can both play suggesting effect from seeing like this, for user, attendant play the effect of necessarily informing, maintain easily.
VD1 in the present embodiment and VD2 are the N4007 model; Light-emitting diode can be installed in the gap location of jack; Partial circuit is installed in gap in socket or the terminal block, and all smears, pastes with coatings (transparent epoxy resin) at partial circuit and indicator light.
Claims (1)
1. discern power supply phase place prompting socket automatically for one kind; It is characterized in that comprising luminescent device, auditory tone cues device and protection device; Wherein luminescent device comprises two red and green luminous diodes about two; Wherein " red end " of the red and green luminous diode in the left side is connected with zero line, and " green end " is connected with live wire; " red end " of the red and green luminous diode in the right is connected with live wire, and " green end " is connected with zero line; One end of auditory tone cues device is connected with zero line, and the other end is connected with ground wire.
