Abstract
The utility model relates to an intelligent power converter special for computers, which comprises a power converting body which is arranged in parallel and provided with a plurality of sockets. The utility model is characterized in that a DC relay is arranged in the utility model and is provided with a plug connected with a USB interface of a computer host machine or other serial ports of the computer host machine, and a conductive contact of the DC relay is arranged on a parallel line of a first socket and a second socket on the lead-in end of the power converting body. The power converter is divided into an uncontrolled socket of the computer host machine and a controlled socket of external facilities; when the computer host machine works, the DC power produced by the USB interface or the serial ports of the computer host machine are used for controlling the contact of the relay to open and close, so the inventive aim that the external facilities are automatically powered on when the computer host machine is turned on and the external facilities are automatically powered off when the computer host machine is turned off is realized. The intelligent power converter special for computers can achieve the aims of saving electric energy and prolonging the service life of the facilities and can eliminate hidden fire troubles.
Description
Technical field
The utility model relates to power supply changeover device, especially a kind of computer special intelligent power supply changeover device.
Technical background
The use of computer has spread to huge numbers of families and each enterprises and institutions, and is as the outside plant of host computer, as display, printer, duplicating machine, active audio amplifier, scanner etc., also indispensable.For the power supply that makes things convenient for the said external facility connects, disposed power supply changeover device usually with a plurality of sockets, still,, after the host computer shutdown, also to progressively turn off the power supply of numerous peripheral hardwares because host computer and peripheral hardware thereof all are independently-powered, just appropriate.Because a lot of people usually turn off behind the main frame away from posts at once, forget and turn off all outer if the power supply of part peripheral hardware causes the outer energising for a long time under the uncared for situation that is located at, both wasted electric energy, influence service life of equipment, might cause disaster hidden-trouble again.Although the power supply changeover device that has is provided with the switch of controllable power, but still inconvenient, it needs people after closing host computer, removes the powered-down converter again.Inconvenient operation, and forget easily.If do not have instant powered-down converter, equally above-mentioned rough sledding can take place.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned power supply changeover device, provides a kind of and can cut off the computer special intelligent power supply changeover device of other outside plant power supply automatically after computer host power supply is closed.
The utility model computer special intelligent power supply changeover device, comprise: with the power source conversion body with a plurality of sockets of parallel way setting, it is characterized in that: be provided with a DC relay in the power source conversion body, DC relay is provided with the plug that is connected with host computer USB interface or other serial port of host computer, and the 220V conductive contact of described DC relay is arranged on first socket and second socket parallel wire of power source conversion body leading-in end.
The design concept and the course of work of the utility model computer special intelligent power supply changeover device are: power supply changeover device is separated into not controlled host computer socket and controlled outside plant socket two parts, when utilizing the host computer operation, the direct supply of other serial port output of its USB interface or host computer, DC relay is got cause its 220V conductive contact closure after electric, the controlled socket power that is connected in parallel on is thereafter connected.When host computer shut down, the direct supply of other serial port output of host computer USB interface or host computer cut out, and causes its 220V conductive contact after the DC relay dead electricity and disconnects, and controlled socket is cut off the electricity supply.Realized that host computer opens then peripheral hardware automatic power, host computer closes the goal of the invention that peripheral hardware is then cut off the electricity supply automatically.
The utility model computer special intelligent power supply changeover device design science, simple and reasonable for structure, easy to use.The use of this computer special intelligent power supply changeover device both can reach saves energy, improved the purpose of service life of equipment, and the elimination disaster hidden-trouble is arranged again.
The concrete structure of the utility model computer special intelligent power supply changeover device is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is a computer special intelligent power supply changeover device electricity theory structure synoptic diagram.
Embodiment
Embodiment: can be clear that from Fig. 1, this is a computer special intelligent power supply changeover device that is provided with 5 sockets, be made up of power source conversion body 1 and a DC relay J, described power source conversion body 1 is by constituting with 5 supply socket 1-1,1-2,1-3,1-4,1-5 of parallel way setting and the attaching plug 2 that is used for being electrically connected with the city.DC relay J is provided with the USB plug 3 that is connected with the host computer USB interface, and the 220V conductive contact of described DC relay J is arranged on first socket 1-1 and second socket 1-2 parallel wire of power source conversion body 1 leading-in end.Thereby above-mentioned supply socket 1-1 is separated into is not subjected to control socket, supply socket 1-2,1-3,1-4,1-5 are for being subjected to control socket.
During use, the attaching plug 2 of this computer special intelligent power supply changeover device is connected with the host computer USB interface with commercial power socket respectively with USB plug 3.The attaching plug of host computer is connected with the socket 1-1 of computer special intelligent power supply changeover device, and the attaching plug of other outside plant is connected with socket 1-2,1-3,1-4, the 1-5 of computer special intelligent power supply changeover device.At this moment, because the line of socket 1-1 and socket 1-2,1-3,1-4,1-5 cuts off, therefore, civil power is only powered to host computer, after opening host computer, host computer USB interface output 5V direct supply gets DC relay J and causes its conductive contact closure after electric, be connected in parallel on thereafter be subjected to control socket 1-2,1-3,1-4,1-5 power connection, to connected other outside plant power supply.When host computer shut down, the 5V direct supply of host computer USB interface output cut out, and disconnected to its conductive contact after the DC relay dead electricity, cause be connected in parallel on thereafter be subjected to control socket 1-2,1-3,1-4,1-5 dump.Connected other outside plant shutdown.
