Description
[technical field]
The present invention relates to a kind of stationary installation and use the device with memory function of this stationary installation, relate in particular to a kind of device with memory function that can be convenient for changing the stationary installation of storage medium and use this stationary installation fixed memory medium.
[background technology]
Along with fast development of computer technology, the user is more and more higher to the requirement of external memory storage, traditional floppy disk, MO dish, CD-RW dish, ZIP dish etc. exist volume big, need disappearance such as driver, can't satisfy user's requirement.Along with the continuous development of storage medium, the continual renovation of host connector, particularly little, in light weight, the safe and reliable medium of volume---the appearance of flash memory (Flash) medium, the maturation of USB standard occurs based on the device with memory function of USB interface technology and flash memory storage technology thereupon.
Existing device with memory function generally comprises host connector, the controller that matches with host connector, storage medium and external shell.This controller electrically connects with host connector and storage medium respectively, and this storage medium is fixedly set in the external shell with controller, and the then outstanding housing of host connector is connected with system host outward.This type of technical scheme with device of memory function can be with reference to No. the 99117225.6th, Chinese patent.
Yet, above-mentioned device solves with memory function the disappearance of floppy disk, MO dish etc., but, because having the storage medium and the controller of the device of memory function is that one is fixed and is installed in the housing, its capacity is fixed, when the user wishes to obtain bigger capacity, must buy a device complete and capacity is bigger with memory function; In addition, when storage medium or controller damage to some extent, also whole device with memory function must be sent and return maintenance even scrap; Therefore, above-mentioned structure with device of memory function not only is inconvenient to use, and has increased user's expense especially, has also caused waste.
The another kind of existing device with memory function 10 that has solved above-mentioned technical matters as shown in figure 12, it comprises host connector 1, matching to merge with motherboard 3, with motherboard 3 with controller 2 that host connector matches is storage medium 5 and the external shell 7 that separates setting with controller 2.Because storage medium 5 is with controller 2 and separates setting, when needs are changed storage medium 5, only need open external shell 7, storage medium 5 taking-ups are got final product.Therefore, this structure with device 10 of memory function can be changed storage medium easily, has reduced cost, economizes on resources, and can avoid unnecessary waste.
But, this device 10 with memory function has following shortcoming at least: at first, because storage medium 5 directly cooperates with motherboard 3, the structure of motherboard 3 need be corresponding with the model and the specification of storage medium 5, therefore, this structure with device 10 of memory function only is fit to the replacing of the storage medium of specification of the same race, and can't adapt to the replacing between the storage medium of different capabilities, therefore can not adjust at storage medium in time and expands according to the market demand.
Secondly, because above-mentioned storage medium 5 is activity with controller 2 and separates setting, install or use in, because of external force or other factors cause storage medium 5 and controller 2 loose contacts easily, thereby can't provide stable electric connection between storage medium 5 and the controller 2.
[summary of the invention]
The object of the present invention is to provide a kind of device that can realize the stationary installation of changing between the different capabilities storage medium and use this stationary installation with memory function.
Another object of the present invention is to provide a kind of device with memory function that can guarantee the stationary installation of electric connection stable between storage medium and the controller and use this stationary installation.
The device that the 3rd purpose of the present invention is to provide simple, the easy to operate stationary installation of a kind of technology and uses this stationary installation with memory function.
The invention provides a kind of device with memory function that can be convenient for changing storage medium, the motherboard that it comprises host connector, match with host connector, controller, the stationary installation of separating the storage medium of setting and matching with storage medium and motherboard respectively with motherboard.This stationary installation matches with storage medium and makes storage medium separate setting with motherboard, when installing and using, storage medium is fixed on the motherboard by stationary installation, thus the electric connection between realization storage medium and the controller; When need changing storage medium, the related stationary installation of storage medium taken off on motherboard get final product.
Compared with prior art, advantage of the present invention is: at first, this stationary installation matches with storage medium storage medium and motherboard independently is provided with, storage medium does not produce directly with motherboard and cooperates, therefore motherboard can adapt to the storage medium of different capabilities specification, thereby makes this device with memory function can realize replacing between the different capabilities storage medium; And this stationary installation can be worked in coordination after manufacturing forms semi-manufacture respectively by separating with motherboard again, thereby can produce adjustment at storage medium in time according to the stock and the market demand.
Secondly, because this storage medium with device of memory function is fixed on the motherboard by stationary installation, therefore can avoid causing problems such as storage medium and controller loose contact by external force or other factors, thus stable electric connection between realization storage medium and the controller.
The 3rd, because this stationary installation is simple in structure, therefore can adopts simple manufacturing process to process, and can change storage medium easily.
