Abstract
A kind of USB device of the replaceable storage chip extension storage space be applied in computing machine and electron trade, comprise left clamp, storage chip expansion interface socket, extension storage space circuit board, right clamp, USB interface, storage chip expansion interface socket and USB interface are connected as a single entity, at plug-in mounting extension storage space, the left side circuit board of storage chip expansion interface socket, and two contact points of extension storage space circuit board right front ends contact with the contact point of USB interface left end and connect, at the left end of storage chip expansion interface socket, left clamp is installed, fixing right clamp is installed in the right part that USB interface is connected with storage chip expansion interface socket.Other parts of storage chip and USB flash disk are structurally distinguished by this device, realize replaceable storage chip, reach the object that can change USB flash disk memory capacity according to demand, than existing USB flash disk phase only many expansion interfaces, this device can arrange in pairs or groups multiple storage chip use, reduce the use cost of USB flash disk on the whole.
Description
Technical field
The utility model relates to the USB device in a kind of replaceable storage chip extension storage space in computing machine and electron trade.
Background technology
At present in computing machine and electron trade,
uSB flash disk, full name USB flash drive, English name " USB flash disk ".It is a kind of miniature high power capacity without the need to phisical drive using USB interface
mobile storageproduct, is connected with computer by USB interface, realizes
plug and play.The address of USB flash disk derives from the novel memory device of one of Netac's science and technology production the earliest, and name is said " flash disk ", uses
uSBinterface connects.After USB flash disk is connected to the USB interface of computer, the data of USB flash disk can exchange with computer.And the equipment of the similar techniques of producing afterwards has carried out Pat. Registration due to Netac, and " flash disk " can not be referred to as again, and rename as homophonic " USB flash disk ".Afterwards, thus this address of USB flash disk was widely known by the people because it is simply easy to remember, was mobile
memory deviceone of.
The composition of USB flash disk generally comprises
shellwith
movement, movement comprises one piece
pCB+
uSBmain control chip+
crystal oscillator+
chip-R,
electric capacity+ USB interface+paster LED+FLASH chip; Shell presses materials classification, has
aBS plastic, bamboo wood, metal, leather sheath, silica gel, PVC software etc.; By genre classification, there are card, pen type, mini, cartoon, commercial affairs, emulation etc.; By Function Classification, have encryption, virus killing, waterproof,
intelligencedeng.Compared to other Portable storage devices, flash disk has many advantages: take up space little, and usual operating speed is very fast, can store more data, and performance is comparatively reliable, disconnects and can not damage hardware when reading and writing, only can obliterated data.This kind of disk uses a large amount of memory device standard of USB.
The maximum advantage of USB flash disk is exactly: to be small and exquisitely easy to carry,
memory capacitygreatly, low price, dependable performance.USB flash disk volume is very little, only size as thumb, and weight is extremely light, and generally at about 15 grams, be particularly suitable for carrying with, we can hang over front it, be hung in key chain, even and put wallet into.General USB flash disk capacity has 2G, 4G, 8G, 16G, 32G, 64G, in addition also has 128G, 256G, 512G, 1T etc.Without any mechanical device in flash disk, anti-seismic performance is extremely strong.In addition, flash disk also has the characteristics such as protection against the tide is antimagnetic, high-low temperature resistant, and safe reliability is fine.
Although USB flash disk is widely used as a kind of memory device easy to carry, but USB flash disk is as memory device, its storage space is just determined when producing, and cannot need expand its storage space in the use in later stage according to the actual of user, otherwise just needs the USB flash disk that more renews.Waste money, waste material resources, that destroys affects social environment protection.Therefore the USB device developing a kind of replaceable storage chip extension storage space is new problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is to provide a kind of USB device of replaceable storage chip extension storage space; this device completes the expansion of storage space by changing storage chip, its novel structure, extensibility are strong, economize on the use of funds; save material resources, be easy to environmental protection.
The purpose of this utility model is achieved in that a kind of USB device of replaceable storage chip extension storage space, comprise left clamp, storage chip expansion interface socket, extension storage space circuit board, right clamp, USB interface, storage chip expansion interface socket and USB interface are connected as a single entity, at plug-in mounting extension storage space, the left side circuit board of storage chip expansion interface socket, and two contact points of extension storage space circuit board right front ends contact with the contact point of USB interface left end and connect, at the left end of storage chip expansion interface socket, left clamp is installed, fixing right clamp is installed in the right part that USB interface is connected with storage chip expansion interface socket.
Main points of the present utility model are its structure.Its principle of work is, this USB device installs storage chip by storage chip expansion interface, after installation, can use as normal USB flash disk.If run into the situation that storage space is too small, so can by storage chip in expansion interface be replaced by the new storage chip having larger storage space.
A kind of USB device of replaceable storage chip extension storage space compared with prior art, have and structurally other parts of storage chip and USB flash disk are distinguished, realize replaceable storage chip, reach the object that can change USB flash disk memory capacity according to demand, than existing USB flash disk phase only many expansion interfaces, this device can arrange in pairs or groups multiple storage chip use, decrease the advantages such as the use cost of USB flash disk on the whole, will be widely used in computing machine and electron trade.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is stereographic map of the present utility model.
Embodiment:
With reference to accompanying drawing, a kind of USB device of replaceable storage chip extension storage space, comprise left clamp 1, storage chip expansion interface socket 2, extension storage space circuit board 3, right clamp 4, USB interface 5, storage chip expansion interface socket 2 and USB interface 5 are connected as a single entity, at plug-in mounting extension storage space, the left side circuit board 3 of storage chip expansion interface socket 2, and two contact points of extension storage space circuit board 3 right front ends contact with the contact point of USB interface 5 left end and connect, at the left end of storage chip expansion interface socket 2, left clamp 1 is installed, fixing right clamp 4 is installed in the right part that USB interface 5 is connected with storage chip expansion interface socket 2.
Using method is, this USB device installs storage chip by storage chip expansion interface, after installation, can use as normal USB flash disk.If run into the situation that storage space is too small, so can by storage chip in expansion interface be replaced by the new storage chip having larger storage space.
