Abstract
Disclosed is a warning device for overload of sockets, comprising an indicating lamp, an inductance coil and a resistor. The warning device for overload of sockets is characterized in that the resistor is connected in series between an output end of the inductance coil and the indicating lamp, the output end of the inductance coil is further connected with one end of a socket, the other end of the socket is connected in parallel with a binding post and the other end of the indicating lamp, and an input end of the inductance coil is connected with the other binding post. The binding posts are connected with a 220V power supply, and after the device is electrified, the indicating lamp is lighted when the inductance quantity of load current flowing through the induction coil exceeds the resistance of the resistor along with the increase of the load, thereby achieving the function of electric equipment monitoring.
Description
Technical field
The present invention relates to a kind of accessory of electrical equipment, is a kind of warning device for the socket overload concretely.
Background technology
The electric current that bears because of load and socket does not mate, hide hidden danger to fire, there is the patent of common purpose to be through retrieval with the present invention: the socket 201020660050X that bringing onto load is reminded, but its so-called load emergency warning lamp is serially connected on socket and the binding post, and a load emergency warning lamp can't bear so large electric current at all.
Summary of the invention
The object of the present invention is to provide a kind of warning device for the socket overload, so that on the basis that guarantees former function of socket, also have with the excessive prompting function of electric loading.
The present invention realizes with following technical scheme: this a kind of warning device for the socket overload is comprised of pilot lamp, telefault, resistor.It is characterized in that, resistor string is connected on the centre of output terminal and the pilot lamp of telefault, the output terminal of telefault is connected with an end of socket simultaneously, and the other end of socket is in parallel with the other end of binding post and pilot lamp, and the input end of telefault is connected with another root binding post.Binding post is connected with the power supply of 220V, after the energising, along with the increase of load, flows through the inductance value of telefault when surpassing the resistance of resistor when load current, pilot lamp will be lit, and realize the monitoring function to consumer.
Pilot lamp is lighted when the load current that sets surpasses 5A, and then the number of turns of telefault is 10 circles, and coil diameter is 2.5mm, and resistor is 1K Ω.
Pilot lamp is lighted when the load current that sets surpasses 10A, and then the number of turns of telefault is 20 circles, and coil diameter is 4mm, and resistor is 1.2K Ω.
Pilot lamp is lighted when the load current that sets surpasses 20A, and then the number of turns of telefault is 30 circles, and coil diameter is 6mm, and resistor is 3K Ω.
Beneficial effect is: the present invention is when used load current is excessive, has the function that pilot lamp is reminded.
Description of drawings
Accompanying drawing is the structural map of a kind of warning device for the socket overload of the present invention.
1. pilot lamp among the figure, 2. binding post, 3. telefault, 4. socket, 5. resistor.
Embodiment
With reference to accompanying drawing, a kind of warning device for the socket overload of the present invention, its structure is comprised of pilot lamp 1, telefault 3, resistor 5.In Figure of description, resistor 5 is serially connected in the centre of output terminal and the pilot lamp 1 of telefault 3, the output terminal of telefault 3 is connected with an end of socket 4 simultaneously, the other end of socket 4 is in parallel with the other end of binding post 2 and pilot lamp 1, and the input end of telefault 3 is connected with another root binding post 2.
Binding post 2 and socket 4 are mated by original socket.
