A main board system of a computer is ensured to be only connected one hard disk and one network within the same time and to be physically isolated with the other hard disk and the other network.

Description

Inside and outside net hard disc physical is isolated change-over switch

The utility model relates to a kind of switch block that is used to switch connection, is a kind ofly to use, be mainly used in the Intranet hard disk be connected switch with the switching of outer net hard disc physical isolation in the network security computing machine.

Develop rapidly along with the Internet technology; go up to government agencies at all levels down to a certain entity; advanced Internet (Internet) technology of numerous and confused employing is set up internal office work net (Intranet) or the classified network of oneself; the opening of Internet is when providing the user to fill part shared resource; also make internet security be subjected to serious threat; be subjected to hacker attacks or, also have spreading unchecked of computer virus etc. as the computer network regular meeting that is connected with Internet by rogue attacks.In order to ensure the safety of internal office work net, can fill the advantage that part is utilized Internet simultaneously again, this just requires the network user to make not connected between the two in Intranet and outer net intercropping physical isolation.The network security computer is exactly to be born under these circumstances.

The secure network computer that can connect Intranet and outer net simultaneously, can comprise a cover mainboard system, peripherals comprises two hard disks (Intranet hard disk and outer net hard disk), a CD-ROM drive, a floppy drive, a Genius mouse, a keyboard and a display, in switching synchronously by the switching controls module that does not have the message exchange loop, in outer net hard disk and the conversion, the outer net network port, carry out the conversion between Intranet and outer net, reach from physically isolating fully, in making at one time, one cover mainboard system can only connect a physical hard disk and a network port, not another physical hard disk that is used by mainboard system and another network port, and then be physically-isolated fully between mainboard system.

The purpose of this utility model is that a kind of inside and outside net hard disc physical of design is isolated change-over switch, aiming at the secure network isolation computer uses, can manually realize the blocked operation between computer motherboard system and inside and outside net hard disk and the inside and outside net network port, realize the inside and outside net physical isolation of computing machine, and lower, the characteristic of simple structure of cost is arranged.

The purpose of this utility model is achieved in that a kind of inside and outside net hard disc physical isolation change-over switch, it is characterized in that: comprise the machine box and be arranged on machine box interior an Intranet hard-disk interface, an outer net hard-disk interface, an inside/outside net hard-disk interface, an inner-mesh network interface, an outer net network interface, an inside/outside net network interface and one group of single-pole double-throw switch (SPDT) group; Respectively hold the corresponding double-throw end and corresponding cutter end that connects described one group of single-pole double-throw switch (SPDT) group of difference on the double-throw end and corresponding cutter end of the described one group of single-pole double-throw switch (SPDT) group of the respectively corresponding connection of each end on each end of Intranet hard-disk interface and outer net hard-disk interface and the inside/outside net hard-disk interface, each end on inner-mesh network interface and the outer net network interface and inside/outside net network interface.

Described one group of single-pole double-throw switch (SPDT) group is one to have the manual toggle switch of switch knob, is arranged in the interlock rotating shaft.

Described switch knob is a key.

Described one group of single-pole double-throw switch (SPDT) group is 42 double-pole double throw switch groups, is arranged in regular turn in the described interlock rotating shaft by 67 double-pole double throw switch groups to constitute.

Described machine box has the computer standard part dimension of CD-ROM drive position or floppy drive position.

A kind of inside and outside net hard disc physical of the present utility model is isolated change-over switch, set Intranet hard-disk interface, outer net hard-disk interface can be respectively for inserting Intranet hard disk, outer net hard disk, and inside/outside net hard-disk interface then is connected with the hard-disk interface of computer motherboard system; Set inner-mesh network interface, outer net network interface are connected with inner-mesh network, outer net network respectively, inside/outside net network interface then is connected with the network interface of computer motherboard, one group of single-pole double-throw switch (SPDT) group then is used for Intranet hard disk or outer net hard disk and is connected with switching between inside/outside net hard-disk interface, and is used for inner-mesh network interface or outer net network interface and is connected with switching between inside/outside net network interface.Only need to insert the key of switch knob, toggle switch just can once be finished the computer motherboard system and be connected with switching between Intranet or outer net, comprises whole hard disc data lines and overall network interface line.The armstrong's patent operation does not definitely have the change-over switch of information circuits, finishes to switch to connect, and is quick, convenient, reliable and with low cost.Inside and outside net hard disc physical of the present utility model is isolated change-over switch, can be set directly in the computing machine, occupies a CD-ROM drive position or floppy drive position, also can independently be arranged on outside the computing machine.

Isolate change-over switch if on the original computing machine of user, connect inside and outside net hard disc physical of the present utility model, only need install a hard disk again additional, just the computing machine of oneself can be changed over a network security isolation computer.

Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing.
