Abstract
The utility model relates to a multifunctional safety socket which is composed of a socket basal body, a nail switch, an indicating lamp and voltage-sensitive resistors. Besides a live line is connected with the nail switch and a fusing body in series, the voltage-sensitive resistors are also respectively connected between the live line and a zero line, between the live line and a ground line, and between the zero line and the ground line. A socket on the socket basal body is designed into an oblate dual-purpose socket and a socket with two grounding poles. The utility model integrates over-current and over-voltage protection and an ordinary switch into entity. Domestic appliances and industrial electronic equipment can be effectively protected.
Description
The utility model relates to a kind of multifunctional protecting socket, belongs to the parts of the jockey that the built-in semiconductor device is arranged.
Existing overvoltage protection socket, as Chinese patent 9122055.6 disclosed sockets, i.e. switch of series connection on the phase line of socket power input, a piezo-resistance in parallel between phase line and zero line.This socket is simple; overvoltage protection to household electrical appliance has played certain effect really; but this socket is only protected overvoltage; do not protect overcurrent; an and piezo-resistance in parallel between live wire and zero line only; if when suffering an idiostatic thunderbolt voltage on live wire and the zero line simultaneously, this protective circuit will lose protective effect.
The purpose of this utility model is to overcome the foregoing invention function singleness, and the shortcoming that the overvoltage protection reliability is little provides a kind of and can protect overvoltage, can protect overcurrent not only and but also can make the multifunctional protecting socket that socket uses, reliability is high.
The utility model is to realize above-mentioned purpose by following measure, is connected with the nail switch 2 and the ceramic fuse 3 (FU) of a quota on the live wire of the input of power circuit; Between live wire and zero line, be respectively equipped with piezo-resistance U separately between live wire and the ground wire and between zero line and ground wire; The pedestal of described safety socket is provided with oblate double-purpose socket and the two poles of the earth band grounding receptacle, and an indicator light in parallel is realized above-mentioned purpose between live wire and zero line.
Embodiment of the present utility model is drawn by appended accompanying drawing.
Fig. 1 is the utility model structure front view;
Fig. 2 is the utility model structure rearview;
Fig. 3 is the utility model circuit theory diagrams.
Among the figure, R colour code resistance, V light-emitting diode, U piezo-resistance
1 is panel, 2 nail switches (S), 3 ceramic fuse-link pottery fuse-links (Fu), 4 over-voltage protecting function spares, 5 indicator lights, 6 socket base, 7 oblate double-purpose sockets, 8 the two poles of the earth band grounding receptacles.
Fuse-link 3 of the present utility model is assembled on the support of being convenient to load and unload; the rated current of nail switch 2 is 10A; indicator light 5 in parallel between live wire and zero line can show the orientation that whether non-transformer is arranged on the safety socket and demonstrate safety socket in the dark intuitively; for improving the unfailing performance of overvoltage protection, between live wire and zero line, zero line and ground wire, live wire and ground wire, also be parallel with the piezo-resistance U of an appropriate value separately.Jack design becomes oblate double-purpose socket 7 and the two poles of the earth band grounding receptacle 8, is applicable to the two poles of the earth plug and the two poles of the earth band ground pin of flat pin or round pin.
When the piezo-resistance two ends applied voltage to particular value, its resistance value sharply diminished, and made thunder-strike current enter the earth by earth electrode, and after moment, piezo-resistance can revert to insulator.
Safety socket of the present utility model; overcurrent protection and overvoltage protection (misphase overvoltage, switching overvoltage and Lightning Over-voltage) organically are combined in the supply socket with regular tap and socket; not only can play overcurrent and superpotential protective effect, also can make socket and use.The utility model can be made surface mounted socket, do the concealed installation socket also can, can also be placed on and make mobile socket on the platform and use, and dependable performance, function are many, a protective device of can yet be regarded as household electrical appliance and industrial electrical equipment.
Claims (1)
1, a kind of multifunctional protecting socket, by resistance R, light-emitting diode V, panel 1, indicator light 5 is formed, and it is characterized in that: be in series with nail switch 2 and ceramic fuse-link 3 on live wire; Between live wire and the zero line, between live wire and the ground wire, be parallel with piezo-resistance U separately between zero line and the ground wire; Socket on the pedestal 6 of described safety socket is oblate double socket 7 and the two poles of the earth band grounding receptacle 8.
