Each entity machine can only be connected with one network or is not connected with a network, and the entity machines have no link with each other, which realizes the pure physical partition, thereby achieving the effect of one machine with a plurality of networks and three-network insulation and being economical, practical, safe and convenient.

Description

Computing machine three net isolation switch devices

Technical field

The utility model relates to the computer network spacer assembly, especially relates to a kind of computing machine three net isolation switch devices.

Background technology

Computer virus is artificial manufacturing, propagate by internet and mobile reservoir, and have certain intelligence, in case enter, be difficult to identification when not showing effect, antivirus software also can't simple filtering or is screened out, if virus outburst may cause the heavy loss of computer user, especially the LAN of important departments such as finance, military affairs, politics, in case invaded by virus, consequence is hardly imaginable, isolate so must carry out three nets.

Three nets are actually two kinds of nets, outer net and Intranet, and outer net refers to the internet, Intranet refers to the LAN (Local Area Network) of native system or this department, promptly makes a general reference Internet and several internal lans.Can interconnectedly then there be secret, safe can saying as inside and outside net, so must isolate.It is computing machine of every net that three nets are isolated effective method, and promptly a people is equipped with many computing machines simultaneously, and this is desirable scheme of course not, and is not only uneconomical but also inconvenient; The method of much utilizing software or using both hard and soft tactics is arranged at present, on a computing machine, realize a plurality of virtual machines, isolate to realize a machine three nets and three nets, but in fact might not be reliable by software.As: publication number is 2,005 10 11 3176.9 three scheme anti-virus computer.

Summary of the invention

The purpose of this utility model is: a kind of computing machine three net isolation switch devices are provided, after loading onto, increasing a hard disk just can make a computing machine become two physical machine, increase by two hard disks and just become three physical machine, and can the rest may be inferred, be implemented on the computing machine and possess a plurality of physical machine, these physical machine can not be moved simultaneously, each physical machine can only insert a net or not network, exhausted mutually nothing contact, reach the partition of pure physics thus, thereby reach the effect of the many nets of a machine, three net isolation.

The purpose of this utility model realizes by following scheme: by a double-pole multithrow switch, above hard disk attachment plug, a lockhole gangbar and the electromagnetism that is used to control the lockhole gangbar inhales the untie-sell nail and attaching plug constitutes.The front end of each cutter of double-pole multithrow switch is connected two groups of power supplys being introduced by attaching plug respectively, the attachment plug that each contact of rear end is connected each hard disk respectively, and lockhole gangbar and the interlock of double-pole multithrow switch, electromagnetism is inhaled the untie-sell nail and is connected with attaching plug.

The rear edge contact of the wherein cutter at the double-pole multithrow switch of the present utility model connects the USB socket of the partition that is connected with corresponding hard disk attachment plug respectively more than, and the USB socket of partition is communicated with a non-transformer USB plug.

The utility model also is provided with continuous shared USB socket and USB plug.

Shared USB socket described in the utility model and USB plug span are connected to double-pole single throw.

First group rear tab of double-pole multithrow switch described in the utility model successively and between the rear tab of second group of switch all cross-over connection the series arm of resistance and light emitting diode is arranged.

Electromagnetism suction untie-sell nail stretches into corresponding lockhole on the lockhole gangbar during the utility model energising, and switch is pinned; Every group of out-put supply line connected a special-purpose USB socket of cutting off simultaneously, connects during energising; Shared USB socket connects with the computing machine USB socket by USB plug, the power supply of the shared USB socket of double-pole single throw may command; Attaching plug directly inserts any supply socket of computing machine can connect required power supply.Be implemented on the computing machine and possess a plurality of physical machine, these physical machine can not be moved simultaneously, and each physical machine can only insert a net or not network, and exhausted mutually do not have a contact, realizes the partition of pure physics thus, thereby reach the effect that the many nets of a machine, three nets are isolated.
