Abstract

The utility model relates to an interface box installed on a 5-inch floppy drive position of a PC (personal computer), which belongs to the computer hardware range. An IDE interface on the PC belongs to a built-in interface. If a hard disk or an optical drive of the IDE interface is required to be temporarily installed on the PC, a machine box is required to be opened; thus, the installation of a power supply interface and a signal interface can be carried out; the use is very inconvenient. The purpose of the utility model is to cause the built-in IDE interface and the power supply interface to be connected to the idle 5-inch floppy drive position at the front side of the machine box of the PC. When another hard disk or optical drive of the IDE interface is required to be suspended, the installation of the new IDE device can be finished without opening the machine box. The utility model provides a method with cheap price, safety and convenient use for information exchange among PCs.

Description

The preposition box of PC ide interface

The present invention is one and is installed in 5 cun locational interface boxs of floppy drive of PC (PC), belongs to the computer hardware scope.

Ide interface on the PC is that PC connects hard disk, the important interface of CD-ROM drive; Be usually located on the mainboard or multifunction card of PC inside, belong to built-in interface.Present most PC has two ide interfaces, and each ide interface can articulate the equipment of two ide interfaces.

Give PC interim hard disk or the CD-ROM drive that an ide interface is installed if desired, then need to open cabinet, just can carry out the installation of power interface and signaling interface, use very inconvenience.

At present, the message exchange between the PC can be passed through the 1.44M floppy drive, network (LAN (Local Area Network) or telecommunications network), and disk cartridge (passing through the parallel port), the hard disk abstraction box, high power capacity floppy drive modes such as (as ZIP) realizes.Wherein the 1.44M floppy drive is the standard configuration of PC, but 1.44M floppy drive capacity is too little, can't satisfy present needs (as graphic image file, large program bag such as WIN95 etc.); LAN is reasonable method, but is subjected to two distance limit between the PC; Telecommunications network is not limited by the region, but expense costliness (modulator-demodular unit and telephone charge), disk cartridge, methods such as high power capacity floppy drive can't extend on all PCs because its cost an arm and a leg (Renminbi is more than thousand yuan) cause PC separate unit cost to increase.

The objective of the invention is built-in ide interface and power interface are received PC cabinet front; When needs are hung the hard disk of an ide interface or CD-ROM drive again, do not need to open cabinet, can finish the installation of new equipment, for the message exchange between the PC provides a kind of cheap, safe and reliable, easy to use method.

With reference to accompanying drawing, cross-sectional sizes and the identical box [1] of 5 cun floppy drives on the PC, be used for the present invention's (preposition box of PC ide interface, be called for short preposition box later on) be fixedly mounted on 5 cun floppy drive positions of PC cabinet, preposition box front is equipped with a removable cover [2], and the use that the inboard of cover plate is used to paste preposition box is noted and sign such as master-slave equipment wire jumping method; There is a plug-in card [3] that is used to install and fix interface preposition box the inside, and 40 pin IDE joints [4] are housed on the plug-in card [3], 4 line power connections [5], three or tetrad DIP toggle switch [6]; The back side such as Fig. 2 of plug-in card [3] leave 40 pin IDE joints [7], 4 line power connections [8], three or tetrad DIP toggle switch [9].

Before the use, open the PC case, preposition box is installed on 5 cun floppy drive positions of a free time, fix with screw; The idle ide interface (second ide interface is better) of PC inside is connected to by 40 pin flat cables on the IDE joint [7] at the preposition box back side, the power interface of free time is received on the power connection [8] at the preposition box back side; According to actual conditions, the principal and subordinate that the DIP joint at the preposition box back side is received another IDE equipment (if present) of same ide interface by 6 core cables or 8 core signal cables controls on the jumper wire device, and the method to set up of master-slave equipment is labeled on the zone bit of preposition box removable cover inboard.

When needing to give the equipment of an ide interface of used PC increase, at first close the power supply of PC, the IDE equipment that will connect is connected with preposition box with the power supply line with the signal wire of getting ready (40 pin flat cable) then, set the wire jumper of principal and subordinate's hard disk, open the power supply of PC again, enter CMOS and be provided with, set the IDE equipment that is articulated, can use.

Adopt the preposition box of ide interface of the present invention, thoroughly change the new IDE equipment of PC increase and need open inconveniences such as cabinet, the separate unit PC only need increase very little cost, then by a standby hard disk, or standby CD-ROM drive, can realize the transmission of high capacity file fast, especially make technology such as " clone " hard disk be able to incisively and vividly performance, be the message exchange between the PC, provide a kind of more quick, the method that has a extensive future.

Claims

A kind of 5 cun locational interface arrangements of floppy drive of PC that are installed in, by box body [1], removable cover [2], plug-in unit fixed head [3], 40 pin IDE joints [4] [7], 4 line power connections [5] [8], three or tetrad DIP toggle switch [6] form.It is characterized in that: (1) box body [1] be cross-sectional sizes with PC on the identical box of cross-sectional sizes of 5 cun floppy drives, the side is left and is installed and fixed the hole; (2) in the front of box body [1] removable cover [2] is installed, the medial surface of cover plate posts to use to be noted and mark; (3) in the inside of box body [1] plug-in card [3] is housed, is used for installing and fixing joint; (4) 40 pin IDE joints are housed on the plug-in card [3], 40 pin IDE joints [7] are left at the back side of plug-in card [3] equally; (5) 4 line power connections [5] are housed on the plug-in card [3], 4 line power connections [8] are left at the back side of plug-in card [3]; (6) one three or tetrad DIP toggle switch [6] are housed on the plug-in card [3], the joint [9] of DIP switch is left at the back side of plug-in card [3], picks out by 6 cores or 8 core signal wires.
