Abstract

The utility model discloses a multifunctional power prompting socket comprising a socket body, the socket body is provided with a power display, the power display is connected with an A/D transition chip, the A/D transition chip is connected with an analog multiplier, the analog multiplier is connected with a voltage sampling module and a current sampling module, and the voltage sampling module and the current sampling module are connected with plug holes; and the multifunctional power prompting socket can real time display a total power on the socket, and the socket is small in size, light in quality, and low in producing cost.

Description

A kind of multi-function power prompting socket
Technical field
The utility model relates to the socket field, relates in particular to a kind of multi-function power prompting socket.
Background technology
Existing socket generally is not with the power prompt facility, and power is socket an important indicator is arranged, require socket institute plug-in device rated power and, less than the rated power of socket, namely can not be with " little, horse go to draw a hand-cart ", otherwise socket can generate heat, affect useful life, damage electrical equipment even cause fire, even the function of minority band power prompting is arranged, but because volume is large, cost is high, be difficult for the marketization.
The utility model content
Technical problem to be solved in the utility model is: for the deficiency that prior art exists, provide a kind of and can show in real time gross power on the socket, the multi-function power prompting socket that volume is little and total price is cheap.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of multi-function power prompting socket, comprise jack body, be provided with power display on the described jack body, described power display be connected the A/D conversion chip, described A/D conversion chip connecting analog multiplier, described analog multiplier connects voltage sampling module and current sampling module, and described voltage sampling module is connected jack with current sampling module.
Furtherly:
Described analog multiplier changes the sampling voltage of voltage sampling module and the sampling current of current sampling module into power.
Described power display is comprised of four charactrons.
Owing to adopted technique scheme, the beneficial effects of the utility model are: this novel multi-function power prompting socket can show the gross power on the socket in real time, and volume is little, and quality is light, low cost of manufacture.
Description of drawings
Fig. 1 is the multi-function power prompting socket figure of the utility model embodiment,
Fig. 2 is the schematic block circuit diagram of the utility model embodiment.
Among the figure: 1. power display, 2. jack body, 3. jack, 4. voltage sampling module, 5. current sampling module, 6. multiplier, 7.A/D conversion chip.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
A kind of multi-function power prompting socket, comprise jack body 2, be provided with power display 1 on the described jack body 2, described power display 1 be connected A/D conversion chip 7, described A/D conversion chip 7 connecting analog multipliers 6, described analog multiplier 6 connects voltage sampling module 4 and current sampling module 5, and described voltage sampling module 4 is connected with current sampling module and is connected jack 3.
Wherein, described analog multiplier 6 changes the sampling voltage of voltage sampling module 4 and the sampling current of current sampling module 5 into power; Described power display 1 is comprised of four charactrons.
