Description
Technical field
The utility model relates to a kind of supply socket, particularly a kind of hand-reset overload overtemperature prote socket.
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, 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; 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 easily damage 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 hand-reset overload overtemperature prote socket is provided; the connection circuit can not automatically reset behind the overload Overtemp. protector cut-out circuit of this socket; thereby the protection electric equipment is avoided destroying, and effectively avoids generating electromagnetic waves when repeatedly repeating to reset because of the overload Overtemp. protector and spark has an accident.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hand-reset overload overtemperature prote socket, 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 PTC, this PTC is in parallel with described overload Overtemp. protector, and this PTC is installed in one with the overload Overtemp. protector, and the heat that PTC is produced can conduct to the overload Overtemp. protector.
As to further elaboration of the present utility model:
In technique scheme, described PTC sticks together mutually with the overload Overtemp. protector, and this overload Overtemp. protector is preferably the bimetal leaf temperature protector.Described hand-reset overload overtemperature prote socket also comprises socket switch and power supply indicator, and this 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 this power supply indicator.
The beneficial effects of the utility model are: overload Overtemp. protector of the present utility model is in parallel with PTC, and PTC and overload Overtemp. protector are installed in one, PTC is thermistor, when load and temperature are normal, the impedance of PTC is much larger than the impedance of overload Overtemp. protector, therefore, only from overload Overtemp. protector process, PTC is in the non operating state that no current passes through to electric current; And when socket overload or excess Temperature; the overload Overtemp. protector cuts off circuit; a small amount of electric current passes through from PTC; the PTC heating of working; its surface temperature maintains a higher temperature; meanwhile; PTC continues heat is conducted to the overload Overtemp. protector; make the temperature of overload Overtemp. protector also be in higher temperature all the time and can not automatically reset or resilience; keep lasting off-state; thereby the protection electric equipment is avoided destroying, and effectively avoids generating electromagnetic waves when repeating to reset because of the overload Overtemp. protector and spark has an accident.On the other hand; when the user needs the turn-on power socket, can pull out first socket power or close socket switch or lay down load, wait for that then overload Overtemp. protector automatic cooling resets; then plug socket power again or open socket switch, supply socket namely recovers the normally state.
