Abstract

The utility model relates to a computer storage device switcher, which comprises a switch, a jumping wire jack plug, a power supply jack plug, a jumping wire connection wire and a power supply connection wire. The switch can be arranged on the front panel, the rear checking surface and the hull of the computer or extend to the outside of the computer. The joints of the switch are connected with the jumping wire jack plug and the power supply jack plug through connection wires; the jumping wire jack plug and the power supply jack plug are respectively connected to the main and auxiliary jumping wire sockets or power supply sockets of a plurality of storage devices. Through shifting the main and auxiliary jumping wires of the storage device, shifting between the start storage device and the operating system can be realized; and through shifting the main and auxiliary jumping wires of the storage device and the power supply, the electric isolation of the unused storage device can be realized. The switch operation replaces the HD or CD main and auxiliary conversion or the hardware operation in replacement, with the effect of simplicity, practicality, safety and convenience.

Description

The Computer Memory Unit switch

Technical field:

The utility model relates to a kind of computer fittings, refers in particular to a kind of Computer Memory Unit switch.

Background technology:

Universal day by day along with computing machine, people need install memory storage identical more than two sometimes in a computing machine, two hard disks or two CD-ROM drives for example are installed, with the share storage content, enlarge storage space or realize the switching of operating system; Also need in memory storage identical more than two, select one sometimes, and all the other no memory storages are isolated on electric.Because computing machine is an essential definite main guiding device and a kind of operating system when starting, and so just need do the plug or the conversion of hardware.Come switching operating system as desire by the master and slave relation that changes memory storage, again the jumper wire plug of jumper connection memory storage; Change memory storage as desire, and it is isolated on electric, will be after each the replacing, reconnect power lead and data line, this operation must be carried out after opening cabinet and backing out screw, and is not only inconvenient, also damages memory storage or other machine element because of misoperation easily.

The switching that realizes operating system also has another method, exactly in same memory storage by the subregion different operating system of packing into, again by the selected necessary operations system of BIOS boot program.This method complicated operation needs certain computer literacy, and when electric fault that this memory storage generation can not be repaired, its total data is with destroyed.

Summary of the invention:

The purpose of this utility model is: a kind of converter that can change its master and slave relation and electric power connection line between a plurality of memory storages that computing machine has mutually is provided, makes computing machine can start different operating system by simple operations with the person.

For reaching the technical scheme that this purpose takes be: a kind of Computer Memory Unit switch, comprise switch, jumper wire plug, attaching plug, the power supply transfer socket, wire jumper connecting line and electric power connection line, the array contact of switch links to each other with several jumper wire plugs by array wire jumper connecting line, the other array contact of switch links to each other with several attaching plugs by the array electric power connection line, jumper wire plug and attaching plug are connected respectively to the master of a plurality of memory storages, in wire jumper socket and supply socket, one end of power supply transfer socket joins by switch and each attaching plug, and the other end links to each other with computer power supply.

The purpose of this utility model can also be achieved through the following technical solutions: switch is installed on the catch at computing machine rear portion, or is installed on the panel of computing machine front portion, or is installed on the case of computer, or extends to the outside of computing machine.

Compared with prior art the utility model has the advantages that: because it is converted to simple switching manipulation with the complicated hardware changing-over, therefore safely, conveniently.Again because switch simple in structure makes it economic, practical.

Number in the figure is described as follows:

1, switch 2, jumper wire plug 3, attaching plug

4, power supply transfer socket 5, wire jumper connecting line 6, electric power connection line

7, memory storage 8, wire jumper socket 9, supply socket

10, computer power supply

Embodiment:

Embodiment 1: master and slave switching mode.

As shown in Figure 1, a kind of Computer Memory Unit switch, comprise switch (1), jumper wire plug (2) and wire jumper connecting line (5), switch (1) is a two-way switch with 4 winding points, and each winding point links to each other with four jumper wire plugs (2) by wire jumper connecting line (5) respectively.

As shown in Figure 3, switch (1) is installed on the front panel of computing machine, memory storage (7) is two hard disks that meet the ide interface standard, 4 winding points of switch (1) link to each other with four jumper wire plugs (2) by wire jumper connecting line (5) respectively, wherein two jumper wire plugs (2) are connected respectively on the master and slave wire jumper socket (8) of a hard disk, and other two jumper wire plugs (2) are connected respectively on the master and slave wire jumper socket (8) of another hard disk.When switch (1) was dialled to one side, first hard disk was connected to Primary Hard Drive by jumper wire plug (2), and second hard disk is connected to from hard disk; When switch (1) was dialled to another side, first hard disk was connected to from hard disk by jumper wire plug (2), and second hard disk is connected to Primary Hard Drive, thereby realizes the switching of master and slave hard disk and operating system.

Embodiment 2: power supply switching mode.

As shown in Figure 2, a kind of Computer Memory Unit switch comprises switch (1), jumper wire plug (2), attaching plug (3), power supply transfer socket (4), wire jumper connecting line (5) and electric power connection line (6).Switch (1) is a two-way switch with 4 winding points, wherein 2 winding points link to each other with four jumper wire plugs (2) by wire jumper connecting line (5) in the shared mode of central contact, and other 2 winding points link to each other with two attaching plugs (3) by two groups of electric power connection lines (6).
