Abstract
A kind of Switching Power Supply, it includes a mains electricity input end, a Switching Power Supply body, a relay and a civil power output, this mains electricity input end is connected with this Switching Power Supply body, the normally opened contact of this relay is connected between this mains electricity input end and this civil power output, one end of the control coil of this relay is connected with the low-voltage output of this power supply body, its another termination low-pressure end ground wire.This civil power output is connected with computer peripheral, when opening Switching Power Supply, the Switching Power Supply body is exported the dc low-voltage electricity and is made this relay get electric adhesive, civil power is the ancillary equipment power supply via this civil power output, close this Switching Power Supply, relay electric-loss disconnects, thereby cuts off the operation of peripheral devices power supply.
Description
[technical field]
The utility model relates to a kind of power supply, refers in particular to a kind of computer switching power supply.
[background technology]
The main effect of Switching Power Supply be will input the high-voltage alternating civil power convert the high stability low-voltage dc power supply of different voltages to, and provide working power for each parts in the main frame.Generally; the work of main frame with such as display; printer; most of operation of peripheral devices power supply such as sound equipment is separate; be that ancillary equipment is by directly power supply of civil power; the user is when using a computer; need open main frame respectively; display; equipment such as printer; and after using a computer; the main frame of also must shutting down computer respectively; display; equipment such as printer, its operation is comparatively loaded down with trivial details, and; the user is using computer after the power supply that cuts off ancillary equipment is forgotten by regular meeting; one, caused the waste of electric power, the two; ancillary equipment is in running order for a long time, must influence the useful life of its functional circuit.
[summary of the invention]
At the deficiency of active computer Switching Power Supply, the purpose of this utility model is to provide a kind of Switching Power Supply of may command computer peripheral working power.
The utility model is to realize above-mentioned purpose by following technical solution: this Switching Power Supply includes a mains electricity input end, a Switching Power Supply body, a relay and a civil power output, this mains electricity input end is connected with this Switching Power Supply body, the normally opened contact of this relay is connected between this mains electricity input end and this civil power output, one end of the control coil of this relay is connected with the low-voltage output of this power supply body, its another termination low-pressure end ground wire.This civil power output is connected with computer peripheral, when opening Switching Power Supply, the Switching Power Supply body is exported the dc low-voltage electricity and is made this relay get electric adhesive, civil power is the ancillary equipment power supply via this civil power output, close this Switching Power Supply, relay electric-loss disconnects, thereby cuts off the operation of peripheral devices power supply.
The beneficial effects of the utility model are: the working power of this Switching Power Supply may command computer peripheral, open or the host power supply of shutting down computer in open or close the operation of peripheral devices power supply, easy user's operation; This Switching Power Supply is to connect a relay and a civil power output forms on the basis of Switching Power Supply of commonly seeing, and its circuit structure is simple, with low cost; Also closed the power supply of peripheral hardware in the time of the Shutdown Hosts power supply, avoided using user when commonly seeing power supply to forget the appearance of the situation of closing the peripheral hardware power supply easily, can save electric power, prolong useful life of peripheral functionality circuit.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the block diagram of a kind of Switching Power Supply of the utility model.
Fig. 2 is the circuit theory schematic diagram of a kind of Switching Power Supply of the utility model.
[embodiment]
As shown in Figure 1, it is the block diagram of the related Switching Power Supply of the utility model, this Switching Power Supply includes a mains electricity input end 1O, a Switching Power Supply body 20, a relay 30 and a civil power output 40, wherein, this civil power output 1O is connected with this Switching Power Supply body 20 and has promptly constituted common Switching Power Supply, and the circuit structure of Switching Power Supply body 20 is identical with common Switching Power Supply.Again in conjunction with shown in Figure 2, the normally opened contact 310 of this relay 30 is connected between this mains electricity input end 10 and this civil power output 40, one end of the control coil 300 of this relay 30 is connected in an output of this Switching Power Supply body 20, its another termination low-pressure end ground wire, this Switching Power Supply body 20 has the output of a plurality of different low-voltage directs, can select different outputs to connect according to the different model of this relay 30; This civil power output 40 be connected such as computer peripherals such as display, printer, scanners and provide working power for it.
When the user uses a computer, open main frame, this Switching Power Supply body 20 is exported dc low-voltages electricity and is made this relay 30 get electric adhesive, civil power is the ancillary equipment power supply via this civil power output 40, close this Switching Power Supply, relay 30 dead electricity disconnect, thereby cut off the operation of peripheral devices power supply.
