Abstract
The utility model belongs to the technical field of electron, in particular to a power supply socket which mainly solves the shortage that the common power supply socket can not detect the electric leakage of electric appliances. The internal part of the power supply socket is connected with a detecting and alarming circuit of electric leakage, wherein, the alarming circuit comprises a sound and a light alarming circuits and a voltage transferring circuit; the sound alarming circuit which is formed by that a resistor r [1] and a luminous tube d [1] are connected in series is connected with both ends of the ground wire and the zero line of a three-core contact point; the light alarming circuit is formed by that a capacitor c, a diode d [3] and a buzzer f are connected in parallel; one end of the light alarming circuit is connected with the zero line of the three-core contact point; the other end of the light alarming circuit is connected with the ground line of the three-core contact point via a voltage transferring assembly.
Description
The utility model belongs to electronic technology field, particularly a kind of supply socket.
As everyone knows, supply socket is the important link between electrical appliance and the power supply.Though three common core supply sockets are provided with the ground wire contact, can not detect the electric leakage information of electric equipment.Some electronic equipments and household electrical appliance usually cause human electric shock's accident because of electric leakage.Thereby can when power consumption equipment powers up, detect the electric leakage situation of power consumption equipment, be a major issue that guarantees personal safety.
The purpose of this utility model is exactly to avoid the electric shock accidents that causes because of equipment electric leakage, and a kind of supply socket that detects leakage function that has is provided.
Realize that the technical solution of the utility model is with the ground wire and the detection end points of zero line as the equipment electric leakage of three core supply sockets, be connected with the electric leakage sound light alarming circuit between it, formation has the supply socket of the sound and light of alarm that leaks electricity.When the alternating voltage by supply socket output, when three-prong plug was transported to electrical appliance, if electrical appliance has leaky, then detecting end points must have the voltage input, and warning circuit is worked at once and sent the sound and light alarm signal.
Followingly describe reasons in structure of the present utility model in detail with reference to accompanying drawing.
Fig. 1 is a block diagram of the present utility model
Fig. 2 is a schematic circuit of the present utility model
See figures.1.and.2, the utility model is by three core receptacle contacts, optical alarm circuit, and voltage transformation and sound warning circuit constitute.Wherein optical alarm circuit is by resistance R
1With luminous tube D
1Form; Voltage conversion circuit is by resistance R
2, diode D
2Form; The audible alarm circuit is by diode D
3, capacitor C and buzzer F constitute.Optical alarm circuit is connected the ground wire and the zero line two ends of three core contacts, and sound alarm circuit also is connected the ground wire and the zero line two ends of three core contacts by voltage conversion circuit.Luminous tube B can select for use light-emitting diode also can select neon tube for use.Need and a capacitor C when selecting diode for use.Luminous tube is installed on the panel of supply socket, and buzzer and other element are installed in the locus in the supply socket housing.When electric equipment had electric leakage, the negative terminal of three core sockets was promptly exported a voltage signal, makes sound light alarming circuit work, and at this moment, the panel luminous tube of supply socket sends the coloured light alarm signal, and housing also sends and ticks simultaneously ... alarm sound.
The utility model since with leakage-current alarm circuit and electrical source socket in one, thereby simple in structure, easy to use; Because the detection sensitivity of supply socket less than exchanging 2.5mA, can effectively guarantee human body safety, be a kind of desirable practical detection of electrical leakage warning supply socket simultaneously.
