The socket of the utility model can save the unload loss of the surrounding equipments of the computer case, so as to save energy and reduce consumption.

Description

The energy-conservation socket of the Special Automatic control of computer

Technical field

The utility model relates to a kind of supply socket, is specifically related to the energy-conservation socket of the Special Automatic control of a kind of computer.

Background technology

At present, popularizing more and more widely of computer, increasing people uses computer, and people's majority when closing computer is that operating system is closed host computer, and equipment that uses simultaneously with host computer such as display, printer, sound equipment etc. still are in the energising holding state, generation wastes, the waste electric energy, but also can influence its useful life, close equipment such as display, printer, sound equipment as needs, then to can not accomplish the purpose of closing simultaneously by manually closing one by one with host computer.

Summary of the invention

The purpose of this utility model provides a kind of computer control electricity-saving socket, it can be switched on or switched off the power supply base power supply of computer peripheral device when starting or closing host computer, thereby computer peripheral device and host computer are started simultaneously or close, save electric energy.

In order to achieve the above object, the technical scheme that the utility model adopted is: the mains-supplied live wire is parallel-connected on the common of one group of contact of starting relay, working relay, is connected in the supply socket after the normally opened contact parallel connection of starting relay, working relay; The normally-closed contact of working relay is connected with the lead-in of the pull-in winding of starting relay, is connected on the push-button switch after the normally opened contact of another group contact of the lead-out wire of the pull-in winding of starting relay and starting relay is in parallel; Be connected on the mains-supplied zero line after the common of another group contact of another tie point of push-button switch and starting relay is in parallel; The pull-in winding of working relay is connected on the attaching plug of computer host power supply box, the pull-in winding work of working relay when computer host power supply box output 12V voltage; Another group switch contact of push-button switch is connected to computer main board POWR pin, is used to replace the switching on and shutting down button of host computer.

When holding state, starting relay, working relay are in open-circuit condition, and the power line of supply socket disconnects, and is in electroless state.

When needs start computer, press the button switch, circuit is connected, the pull-in winding work of starting relay, the normally opened contact closure of starting relay, supply socket has the electricity input, launch computer, after push-button switch unclamped, another group contacting of starting relay formed the loop, and the pull-in winding of starting relay is worked on; Its host power supply box output 12V voltage is to the pull-in winding of working relay behind launch computer, the normally opened contact closure of working relay, normally-closed contact disconnects, the circuit of the pull-in winding of starting relay disconnects, starting relay is not worked, and the power supply of supply socket is transformed into working relay by starting relay.

When host computer shut down, the host power supply box was not exported electricity, and working relay is not worked, and the power line of supply socket disconnects, and is in holding state.

The utility model is simple in structure, cost of manufacture is low, and the operating state that can effectively utilize host computer is controlled the operating state of equipment such as display, printer, sound equipment in real time, saves wasting of host computer peripheral equipment, help prolonging its useful life, reach beneficial effect energy-conservation, consumption reduction.
