Description
Technical field
The utility model relates to a kind of supply socket, particularly a kind of overload overtemperature prote socket with warning function.
Background technology
Supply socket (Power socket) is the electric equipment that power interface is provided for various electrical equipment, uses extensively in design of residence, lives closely related with people.In the prior art, supply socket only provides connection function for various electrical equipment usually, when the power of various electrical equipment during large or overload, particularly bad at socket connector, contact resistance between plug, the socket will increase, and contact resistance just can produce during energising is enough to plug, socket are burnt mashed power loss.In case it is mashed that plug, socket burn, and except meeting allows the user touch the live part, also can produce intereelectrode short-circuit, causes the generation of electric shock injures and deaths and electrical fire accident.
Progress along with technology; people have designed the socket with the overload overheat protection function; for example: Chinese patent 200920289378.2 discloses a kind of multifunctional power socket; comprise jack body; also comprise timer, overheat protector; timer is serially connected with in the power circuit of socket, and overheat protector is serially connected between the load of timer and socket.When the socket temperature reaches or exceed the protection temperature value of overheat protector, the overheat protector circuit of just can cutting off the electricity supply, thus it is mashed to avoid plug, socket to burn, and gets an electric shock the generation of the problems such as short circuit, accident.
Yet; above-mentioned socket with the overload overheat protection function lacks warning function in actual applications; when overheat protector cuts off socket circuit; the user does not often know owing to appliance power excessive or overload or the bad problem that causes of socket itself, thereby can not in time reduce the loading level of electrical equipment or get rid of targetedly unusual.Moreover, because the overload Overtemp. protector is generally the bimetal leaf temperature protector, have auto-reset function, when temperature is high, bimetal leaf temperature protector automatic cut-off power, after temperature reduced, the bimetal leaf temperature protector recovered again the conducting of power supply automatically; So; above-mentioned with the overload overheat protection function socket in actual application; owing to do not reach alarm; even appliance circuit is under the fault condition; socket also can make socket switch between cut-out circuit and connection circuit two states incessantly because of the auto-reset function of overload Overtemp. protector; so not only damage easily electric equipment, and can be because the overload Overtemp. protector generates electromagnetic waves reset the time and spark causes larger peril to occur.
The utility model content
The technical problems to be solved in the utility model is for above-mentioned deficiency of the prior art; a kind of overload overtemperature prote socket with warning function is provided; this socket can in time give the alarm when the overload Overtemp. protector cuts off circuit, makes the user know unusually at once, and in time eliminates unusual.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of overload overtemperature prote socket with warning function, comprise power input, overload Overtemp. protector and loading interfaces, behind the live wire serial connection overload Overtemp. protector of described power input, be electrically connected with loading interfaces one inserted terminal, another inserted terminal of the zero line of described power input and loading interfaces is electrically connected; Also comprise warning circuit, this warning circuit is in parallel with described overload Overtemp. protector.
As to further elaboration of the present utility model:
Described warning circuit comprises dropping resistor, rectifier diode, alarm and filter capacitor, and described dropping resistor, rectifier diode and alarm are in series, and described filter capacitor and alarm are in parallel.
Further, described rectifier diode comprises the first rectifier diode and the second rectifier diode, and the first rectifier diode, alarm, the second rectifier diode are sequentially connected.Described alarm is LED lamp or buzzer.The resistance of described dropping resistor is 200 K Ω～400K Ω, is preferably 300K Ω, and the appearance value of described filter capacitor is 50 μ F～150 μ F, is preferably 100 μ F.
Further, this overload overtemperature prote socket with warning function also comprises socket switch and power supply indicator, and described socket switch is in order to cutting off or the turn-on power inlet circuit, and in order to the conducting of indicating the power input circuit whether described power supply indicator.
The beneficial effects of the utility model are: warning circuit of the present utility model is in parallel with the overload Overtemp. protector, when the socket temperature is low, because the impedance of warning circuit is much larger than the impedance of overload Overtemp. protector, therefore, only from overload Overtemp. protector process, warning circuit is in the non operating state that no current passes through to electric current; And when the socket excess Temperature, the overload Overtemp. protector cuts off circuit, a small amount of electric current process from warning circuit, and warning circuit is conducting and giving the alarm, therefore, the user can know unusually at once, and in time eliminates the abnormal problem of electrical equipment or socket itself.
