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, there is more disappearance in actual applications in above-mentioned socket with the overload overheat protection function: the limiting temperature value that one, overheat protector cut off circuit operation is higher, although it has played good protection to socket, but to a certain extent, still there are the mashed plugs and sockets of burning and electric shock short-circuit risks; Two, the excessive or overload of appliance power; and the bad problem of socket itself; if can in time find; mostly can in time be solved; yet above-mentioned socket with the overload overheat protection function does not but have warning function; it is unusual to tell in time more which kind of appears in the user, thereby the user can't also get rid of unusually in no appearance overload overtemperature situation in advance.
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, and this socket can give warning in advance before overtemperature, and it is unusual to make the user get rid of in advance when also the overload of appearance overtemperature situation.
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 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 be connected to early warning circuit between the live wire of described power input and the zero line, this early warning circuit is reached in parallel with the circuit that overload Overtemp. protector and loading interfaces form; The early warning temperature value of described early warning circuit is lower than the protection temperature value of overload Overtemp. protector.
As to further elaboration of the present utility model:
Described early warning circuit comprises often opens thermostat, dropping resistor, rectifier diode, alarm, and filter capacitor, and described thermostat, dropping resistor, rectifier diode and the alarm often opened is 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: because the other early warning circuit that is parallel with of the circuit that overload Overtemp. protector and loading interfaces form, and the early warning temperature value of early warning circuit is lower than the protection temperature value of overload Overtemp. protector, the conducting temperature value of namely often opening thermostat is lower than the break-off signal value of overload Overtemp. protector, therefore, when the socket temperature rises to the early warning temperature value of early warning circuit, often open the thermostat conducting, early warning circuit gives the alarm, make the user also not occur in the overload overtemperature situation, get rid of in advance unusual when namely not reaching the protection temperature value of overload Overtemp. protector; On the other hand, even if the user does not place oneself near socket, and can't know the alarm of socket the time, because socket also has overload Overtemp. protector circuit, thereby can not make socket burn mashed and the accidents such as breaking out of fire yet.
