The radiating subassembly volume of general personal computer power supply unit, floppy drive and motherboard volume big, that use is big or the part layout is improper and because of reasons such as various winding displacement connections, and cause this main frame framework bulky, wherein improper with the part layout especially and use various winding displacement connection to be wasted space proportion maximum, connect CD-ROM drive, Winchester disk drive, floppy drive etc. as motherboard via winding displacement, the space that it is wasted even surpass the volume of motherboard, CD-ROM drive, floppy drive, this is the huge main cause of main frame.

Therefore, the generation of microcomputer is just arranged, though this microcomputer improve the shortcoming that above-mentioned personal computer produces, but general microcomputer is because of the restriction for fear of the space, so can't allow the user be provided with or change required extension facility arbitrarily in addition, and many hardware components all on motherboard the mode with circuit design thereon affixed, not only can't allow the user select to be fit to the equipment of oneself, and increase formality and cost that motherboard is caused relatively when making, and cause still having inconvenience in the use of microcomputer; So, so general known microcomputer can not meet the required of user on reality is used.

Summary of the invention

Fundamental purpose of the present utility model is to provide a kind of expanding device of microcomputer, this microcomputer is cooperated the docking groove of expansion unit by the Plug Division of motherboard, this microcomputer is had can be for replacing the function that expands required extension facility in addition, required during with realistic use, and motherboard is reached be easy to the effect of making and reducing cost.

The purpose of this utility model is achieved in that a kind of expanding device of microcomputer, includes:

One casing, an end of this casing is provided with several perforates, and the other end has most perforation;

One motherboard, this motherboard is arranged in the above-mentioned casing, this motherboard is provided with most electronic packages and storage device, and is provided with most connectors in this motherboard corresponding to perforation place of the casing other end, and at least one side edge in this motherboard is provided with the Plug Division in addition;

One expansion unit, this expansion unit by an extension circuit plate, and one be arranged at the docking groove that this extension circuit plate simultaneously goes up and dock with the Plug Division of above-mentioned motherboard and constituted.

These casing two ends have a front shroud and a back shroud respectively.

This docking groove is connected with the extension circuit plate in vertical mode.

This docking groove is connected with the extension circuit plate in a parallel manner.

This storage device is CD-ROM drive and hard disk.

This front shroud is provided with CD-ROM drive and releases mouth.

Embodiment

See also Fig. 1, Fig. 2 and shown in Figure 3, be respectively the profile status synoptic diagram after perspective exploded view of the present utility model, the utility model inserting state synoptic diagram and the utility model are assembled.As shown in the figure: the expanding device of a kind of microcomputer of the present utility model, it is made of a casing 1, a motherboard 2 and an expansion unit 3, can make this microcomputer cooperate expansion unit to have by motherboard can be for replacing the function that expands required extension facility in addition, required during with realistic use, and motherboard is reached be easy to the effect of making and reducing cost.

The above-mentioned casing of carrying 1 two ends have a front shroud 11 and a back shroud 12 respectively, this front shroud 11 is provided with CD-ROM drive and releases mouth 111 and perforate 112 (storage device according to present embodiment is that CD-ROM drive and hard disk are established), and this back shroud 12 has most perforation 121, and this forward and backward

cover plate

11,12 is affixed with two ends of casing 1 by most fixation kits 13.

This motherboard 2 is arranged in the above-mentioned casing 1, and this motherboard 2 is provided with the central processing unit (CPU) that storage device (be with the present embodiment example its be the CD-ROM drive of repeatedly putting mutually 21 and hard disk 22), most electronic package 23 and collocation have fan 231, and this CD-ROM drive 21 is released mouth 111 corresponding to the CD of casing 1 front shroud 11, and be provided with and the majority of back shroud 12 121 corresponding connector 24 of boring a hole in this motherboard 2, at least one side edge in this motherboard 2 is provided with Plug Division 25 in addition, and this Plug Division 25 can be golden finger.

This expansion unit 3 by an extension circuit plate 31, and one be arranged at the docking groove 32 that this extension circuit plate 31 one sides go up and dock with the Plug Division 25 of above-mentioned motherboard 2 and constituted, and the mode that this docking groove 32 can be vertical is connected with extension circuit plate 31.So, constitute the expanding device of a brand-new microcomputer by above-mentioned structure.
