Abstract
The utility model relates to a multifunctional power supply socket which is mainly composed of a rectifying diode D, an electrical leakage alarm circuit, a plurality of power supply sockets and a plurality of voltage display circuits. The utility model can make tricolored light display for the under voltage condition, the normal condition and the overvoltage condition of the power supply voltage and make alarm for the electrical leakage of the outer casing of an electric appliance. Meanwhile, the multifunctional power supply socket is also used for an indication device for on-off of the power supply. The multifunctional power supply socket of the utility model has the advantages of novel design, easy fabrication, low cost and visual display. The multifunctional power supply socket is suitable for places, such as families, enterprises institutions, etc.
Description
The utility model is a kind of multifunctional power socket, and it belongs to daily electric product, can be widely used in enterprises and institutions and family.
In prior art, the function singleness of supply socket, intuitively display power supply voltage can not carry out leakage-current alarm.Measure supply voltage, must use needle dc voltmeter, simultaneously, for preventing electric leakage, also need to adopt earth leakage protective device, and these products are independently of one another, complex structure is installed trouble, uses very inconvenient.
The purpose of this utility model is to provide to people a kind of multifunctional power socket of practicality, and it is display power supply voltage intuitively, also can carry out leakage-current alarm, and have simple in structure, clear display, practical advantage.
Solution of the present utility model is that this multifunctional power socket is by rectifier diode D, leakage-current alarm circuit and several supply sockets, a plurality of voltage display circuits are formed, a plurality of voltage display circuits are connected in parallel, its contact 3 is connected in series with rectifier diode D, the contact 2 of rectifier diode D and the contact 4 of voltage display circuit are connected with two outer contacts 1,6 of this socket respectively, several supply sockets are connected in parallel in contact 2,5 successively, the contact 8 of leakage-current alarm circuit connects zero-power line contact 6, and its contact 7 is connected electric appliance casing.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is the schematic circuit of multifunctional power socket.
As shown in the figure, this multifunctional power socket is by several or three supply socket A, B, C, rectifier diode D, and leakage-current alarm circuit and a plurality of or three voltage display circuits are formed, and three voltage display circuits are by resistance R
1, R
2, R
3Respectively with LED
1, LED
2, LED
3The circuit that is connected in series and forms, be connected in parallel between the voltage display circuit, its contact 3 is connected in series with rectifier diode D, the contact 2 of rectifier diode D and the contact 4 of voltage display circuit are connected with two outer contacts 1,6 of this socket respectively, on the power supply phase line between contact 1 and 2, mains switch k is housed, three supply socket A, B, C are connected in parallel in contact 2,5 successively, and the contact 8 of leakage-current alarm circuit connects zero-power line contact 6, and its contact 7 is connected electric appliance casing.Here, the leakage-current alarm circuit is by neon bulb 9 and resistance R
4The circuit that is connected in series and forms.
According to requirement of the present utility model, when supply voltage reaches V when volt, make and flow through resistance R, the electric current I on the LED just in time equals the minimum glow current of LED, and this moment, light-emitting diode began luminously, demonstrated the supply voltage situation.Among the embodiment of the present utility model, select the supply voltage show value of three class, display voltage directly perceived during as work, they are under-voltage V
1(150～190 volts), normal V
2(190～240 volts), overvoltage V
3(more than 240 volts), and represent with gold-tinted, green glow, ruddiness respectively, so just can clearly show the operating voltage of electrical equipment.Leakage-current alarm circuit luminous by neon bulb 9 in like manner carried out continual early alert to the electric leakage that makes electrical appliance and the earth unfavorable condition that connects of earth connection, and the utility model also can be made the on/off indicating device and use.
Above-mentioned resistance R
1, R
2, R
3Resistance can calculate by following formula:
R
1＝ (0.45V1)/(I) ＝ (0.45×150)/(I) ＝ 67.5/(I)
R
2＝ (0.45V
2)/(I) ＝ (0.45×190)/(I) ＝ 85.5/(I)
R
3＝ (0.45V
3)/(I) ＝ (0.45×240)/(I) ＝ 108/(I)
In the formula: the minimum glow current of each light-emitting diode of I-;
0.45-halfwave rectifier efficiency value;
V
1-under-voltage indication range lower limit;
V
2-normal voltage indication range lower limit;
V
3-overvoltage indication range lower limit;
Most preferred embodiment of the present utility model is that rectifier diode D is 1A/400V, resistance R
1Be 22.5k Ω, resistance R
2Be 28.5k Ω, resistance R
3Be 36k Ω, resistance R
4Be 500k Ω, the power of resistance is 0.5W.
