Description

A kind of computer equipment circuit breaker

Technical field

The utility model relates to a kind of electric socket that connects computer and ancillary equipment, belongs to computer power switch device technology field.

Background technology

Computer is after shutdown, and main frame and peripheral equipment (such as printer, audio amplifier, display etc.) can not cut off the power supply fully, but under a kind of stand-by operation state operating on low voltage, still in involuntary power consumption.According to measuring and calculating, main frame, display, printer, ADSL Network Termination, router etc. are under ideal case, and its whole stand-by power consumptions are wanted more than the 16W.Worked 6 hours every day according to every computer, standby 2 hours was shut down 16 hours, calculated with 5,000 ten thousand of the owning amounts that present China computer is the most conservative, and every year, only one of off-mode power consumption can reach 6.2 hundred million degree electricity, was a sizable numeral.In order to change this situation, the user can pull up power plug behind the main frame of shutting down computer, and is unpractical but frequently pull up latch in the work, is difficult to accomplish.Therefore, the technical staff has also developed some special equipments, can allow computer accomplish the function of economizing on electricity, but install cumbersome, generally want the computernik of specialty to install, this equipment also can be accomplished zero-power behind computer shutdown, but the power consumption after start is more a lot of than height when this equipment is not installed, and energy-conservation power savings is not obvious.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of computer equipment circuit breaker that can cut off main frame and ancillary equipment behind computer shutdown automatically.

The technical scheme that solves the problems of the technologies described above is:

A kind of computer equipment circuit breaker, its agent structure is a plate, there are a plurality of sockets on the plate surface, the power line of plate is connected with external power supply by plug, its improvements are, also have a relay and timer in plate, and four interior pin power interfaces of relay coil two ends and main frame are connected, the switch contact and the timer of relay are in parallel, and the two ends of parallel circuits are serially connected in the interior main circuit of plate.

Aforementioned calculation machine equipment circuit breaker, described timer timing are 100-120 second.

This computer equipment circuit breaker can cut off the main circuit of plate automatically after main frame is closed, make the main frame and other ancillary equipment that are connected on the plate cut off the power supply, and has thoroughly solved the postboost standby power consumption problem of computer and ancillary equipment.The utility model is reasonable in design, making is simple, cheap, easy to use, be the very strong computer battery saving arrangement of a kind of practicality, good economic benefits is arranged, be worthy to be popularized.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model.

Mark is as follows among the figure: plate 1, socket 2, plug 3, timer 4, relay 5, computer 6, printer 7, audio amplifier 8, display 9, attachment plug 10, relay coil J1, relay switch contacts J1-1, power supply E

Embodiment

Shown in Figure 1, agent structure of the present utility model is a plate 1, and there are a plurality of sockets 2 on plate 1 surface, and socket 2 can connect plurality of devices such as computer 6, printer 7, audio amplifier 8, display 9, ADSL terminal.Inventive point of the present utility model is, a timer 4 and a relay 5 also have been installed in plate 1.The coil two ends of relay 5 are connected with four pin power interfaces in computer 6 main frames by attachment plug 10, and the switch contact of relay 5 and timer 4 are in parallel, and the two ends of parallel circuits are serially connected in the main circuit in the plate 1.

Shown in Figure 2, in the circuit diagram of the present utility model, four pin power interfaces in relay coil J1 two ends and the main frame are connected, and the two ends of relay switch contacts J1-1 and timer 4 are in parallel, one termination power E of parallel circuits, the socket in parallel of the various electrical appliances of another termination.The timing of timer 4 is 100-120 second.

The model of the relay of an embodiment of the present utility model is JQx-14FC, and the model of timer is cfj-60.

The course of work of the present utility model is:

Computer and ancillary equipment are inserted in the socket of wiring board, the plug of wiring board is connected with the 220V power supply, when not starting timer, no-voltage on the plate.When needing computer operation, start timer, at this moment power connection, computer and ancillary equipment energising, then start computer, produce in the computer+to relay coil, at this moment connect in the circuit breaker by the relay switch contacts in parallel with timer by four pin power interfaces for 5V voltage, work simultaneously with timer, external power supply is powered to main frame by timer and relay switch contacts simultaneously.To timer timing 120 seconds, timer automatic disconnection, and the relay switch contacts maintenance is connected, and this computer-chronograph and ancillary equipment are still connected with external power supply, enter the state of operate as normal.When shutting down computer main frame, computer enters holding state, the inner four pin power interfaces of main frame offer the loss of voltage of low pressure+5V of the relay coil of circuit breaker, the circuit breaker coil losing electricity, the relay switch contacts in parallel with timer disconnects, because timer timing in the middle of computer uses finishes, this moment, timer disconnected already, so the main power line that plate is connected with external power disconnects the purpose that realization computer and 220V external power supply disconnect fully.

The process that the utility model listed examples is intended to further to illustrate the structure of computer equipment circuit breaker and realizes outage, and protection range of the present utility model is not constituted any restriction.
