Description

Computer power one keying socket

Affiliated technical field

The utility model relates to a kind of socket, refers in particular to a kind of computer power socket.

Background technology

Along with computer (PC) is popularized use, increasing computer peripheral device enters in people's daily life, as: printer, scanner, External modem and active audio amplifier etc.At present, computer user generally adopts common socket and many mouthfuls of common sockets (also claiming plate), and these supply sockets can not adapt to the reasonable use of computer and peripheral hardware far away.Though present computer host power supply adopts intelligent on-off mode, but by software switch machine or remote control switch, but the power supply of computer peripheral equipment must be by hand switch one by one, be the loaded down with trivial details thing of part really, forgotten once in a while that (this can necessarily shouldn't be careless! ), energising reduction of service life was a minor matter when waste electric energy and peripheral hardware were long, these peripheral hardwares overheated damage of energising when long but become ordinary affair, has to cause user's attention; In addition, overtension, the external clutter of electrical network, the unexpected power failure or the chance thunderbolt are threatening computer peripheral equipment at any time during the electrical network ebb; What could not look simultaneously is computer peripheral equipment energising when long, equipment heating and damage heating, thereby initiation fire.Often there is report to damage heating initiation fire, disastrous incident because of computer peripheral equipment.

Agree craving for of many computers user, though once the someone designed and had computer power socket, computer private jack or the power supply state control device etc. that cut-off function, but they still exist following weak point, are difficult to really satisfy computer and peripheral hardware and use needs, can not promote the use of.

1, all computer peripheral equipments are arranged along with the startup of the host computer also socket of power-on simultaneously, but its when starting immediate current excessive; In addition, so open and close, produce the mutation voltage pulse, very unfavorable computer and peripheral hardware use, even threaten computer and peripheral hardware.

2, the used element of some socket internal circuit is more, and self component wear rate is higher, and reliability is relatively poor.

3, some socket adopts two diode reverse parallel connections or resistance series connection host computer seat one end, makes host computer current signal Acquisition Circuit, and resistance easily generates heat; And the employing diode, in case one of them damages, the power supply of host computer then is rectified into half-wave, consequence is hardly imaginable.

Though the socket that 3, has has adopted overload protective device, because the circuit of its design is unreasonable, when the peripheral hardware overload protective device started, host computer and display also were cut off power supply simultaneously and can't work.At this moment, the file that all are not in time preserved or other operation achievements also are thrown into the eastward flowing stream thereupon, and be too late to repent.

4, a kind of " linkage that can start simultaneously with host computer " arranged, because now mostly be soft starting mode, so there has not been use value with computer host power supply.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned many weak points that exist in the prior art, and a kind of computer power one keying socket is provided, and accomplishes that computer and peripheral hardware power supply control automatically, and has that switching on and shutting down postpone, anti-lightning strike, overvoltage overload protection function.

For achieving the above object, the solution that the utility model is taked is: a kind of computer power one keying socket, comprise that drain pan, panel and a plurality of jacks of multi-national standard and shape plug that can be applicable to provided thereon are computer host power supply socket Z1, display power supply socket Z2, peripheral hardware supply socket Z3～Zn and battery main switch SW and are installed in the interior electronic circuit board of described socket, it is characterized in that being provided with the overload protection reset button in a side of drain pan, described electronic circuit board includes signal amplification circuit, delay circuit, output control circuit T3; Delay circuit is made up of master delay circuit U 1 and off delay circuit; After civil power is taken over control thunderbolt element A1, over-voltage protection element LG1 and electric source filter circuit, one tunnel L that meets computer host power supply socket Z1 holds in the civil power L end, and the N end electric wire of computer host power supply socket Z1 passes ring-like electric current mutual inductor L3 and connects the electric source filter circuit output; Ring-like electric current mutual inductor L3 output termination signal amplification circuit connects master delay circuit U 1 thereafter, master delay circuit U 1 output termination output control circuit T3, and the anode of output control circuit T3 is succeeded electrical equipment JK1; At ring-like electric current mutual inductor L3 and the indirect off delay circuit of signal amplification circuit; Civil power L holds another road to divide two the tunnel again through relay J K1 sound contact, wherein one the tunnel directly is connected to display power supply socket Z2, each other peripheral hardware supply socket Z3～Zn of another Lu Zejing overload protector A2 tap; Display power supply socket Z2, peripheral hardware supply socket Z3～Zn other end all link to each other with the electric source filter circuit output.

In the time will starting computer system, as long as press the host computer start button, just patch automatic loading power after the peripheral hardware on the utility model can be delayed time about two seconds; In the time will closing computer system, along with making host computer, operating system software closes automatically simultaneously, and behind about five seconds of delaying time, all computer peripheral equipments that patch on the utility model just can be cut off the electricity supply automatically; In the computer use, when the phenomenon that occurs transshipping started overload protective device, the utility model cut off all the peripheral hardware power supplys except that main frame and display; At this moment, withdraw from and close computer system after can preserving the file do not preserved or other operation achievements.The utility model also has anti-lightning strike, overvoltage overload protection function, can effectively avoid the computer system damage that has an accident.Contact good and durable in use between each plug and socket.Its internal electronics element is few, perfect in shape and function and advantages of simpleization, reduces the probability of damage of self components and parts, strengthens reliable and practical property.
