The utility model discloses domestic safety protection socket circuit structure is simple, components and parts are few, has increased the leakage detection module on the basis of ordinary three -phase socket, can send ruddiness warning and chimes of doom when meetting the load electric leakage, has still set up the undulant suppression component of commercial power at the mains side simultaneously, reduces the spurious triggering probability, consequently has the advantage that convenient to use, stable performance and cost of manufacture are low.
Description
Technical field
The utility model relates to a kind of socket, specifically a kind of domestic safety protection socket.
Background technology
Socket is the most frequently used electric component arrived in people's daily life and industrial production, it can complete line voltage and join to the electric energy of power consumption equipment, and some old household electrical appliances are because aging, the reasons such as improper use easily cause leaky, not only power consumption can be increased, and seriously reduce the life-span of household electrical appliances, when simultaneously electrical leakage quantity is larger can serious time the human body touching electrical equipment that leaks electricity may cause damage by human body, especially child and old man's resistance poor, easily cause serious consequence, in the market with the most complex structure of socket of leakage protection, cost is higher, therefore popularity rate is not high.
Utility model content
The purpose of this utility model is the domestic safety protection socket providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of domestic safety protection socket, comprise transient voltage suppressor diode DW, electric capacity C1, resistance R1, with chip IC 1, one end contact resistance R1 of described electric capacity C1 and the pin 1 of socket A, the pin 2 of socket A connects transient voltage suppressor diode DW and 220V line voltage, the other end of transient voltage suppressor diode DW connects electric capacity C2, the pin 2 of chip IC 1, the other end of 220V line voltage and the pin 3 of socket A, the other end of electric capacity C1 connects the anode of diode D1 and the other end of resistance R1, the negative electrode of diode D1 connects the anode of diode D2, the negative electrode of diode D2 connects electric capacity C2, buzzer B, the pin 4 of chip IC 1 and the pin 5 of chip IC 1, the two ends of the pin 6 of chip IC 1 and the pin 7 difference contact resistance R2 of chip IC 1, the pin 3 of chip IC 1 connects the other end of buzzer B, the model of described chip IC 1 is KD9561.
As preferred version of the present utility model: described diode D2 is red light-emitting diode.
Compared with prior art, the beneficial effects of the utility model are: the utility model domestic safety protection socket circuit structure is simple, components and parts are few, the basis of common three-phase socket adds detection of electrical leakage module, ruddiness warning and chimes of doom can be sent when running into load electric leakage, also be provided with city's electro-mechanical wave suppression element at mains side simultaneously, reduce false triggering probability, therefore there is easy to use, stable performance and the low advantage of cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of domestic safety protection socket.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of domestic safety protection socket, comprise transient voltage suppressor diode DW, electric capacity C1, resistance R1, with chip IC 1, one end contact resistance R1 of described electric capacity C1 and the pin 1 of socket A, the pin 2 of socket A connects transient voltage suppressor diode DW and 220V line voltage, the other end of transient voltage suppressor diode DW connects electric capacity C2, the pin 2 of chip IC 1, the other end of 220V line voltage and the pin 3 of socket A, the other end of electric capacity C1 connects the anode of diode D1 and the other end of resistance R1, the negative electrode of diode D1 connects the anode of diode D2, the negative electrode of diode D2 connects electric capacity C2, buzzer B, the pin 4 of chip IC 1 and the pin 5 of chip IC 1, the two ends of the pin 6 of chip IC 1 and the pin 7 difference contact resistance R2 of chip IC 1, the pin 3 of chip IC 1 connects the other end of buzzer B, the model of described chip IC 1 is KD9561.
Diode D2 is red light-emitting diode.
Operation principle of the present utility model is: resistance R1, electric capacity C1 and diode D1, capacitor C2 etc. constitute simple and easy halfwave rectifier filter circuit of pressure-stabilizing, provide stable 5V direct voltage to warning circuit; The peak voltage clamper that city's electro-mechanical wave can produce by transient voltage suppressor diode DW, to safety value, increases the stability of input voltage, and simulated sound integrated circuit (IC) 1 and its external osc resistor R2, buzzer B constitute simulation police whistle sound generator.At ordinary times, because the left end of R1 connects with the earth terminals 1 pin unsettled in socket A, therefore warning circuit is without working power, and light-emitting diode D2 is not luminous, and B is noiseless.
Once the load access socket A of body leakage, leakage current just can form loop by the earth string holes 1 pin of the metal shell of phase line 2 pin of A, household electrical appliance, A, warning circuit and electrical network zero line (ground wire).Leakage current, by after R1 current limliting, D1 halfwave rectifier, makes D2 light; Meanwhile, 5V direct voltage, after C2 filtering, the simulated sound generator work that IC1 and R2 is formed, namely B sends police whistle sound, and reminding user keeps in repair the timely power-off of electrical equipment.
