Description

A kind of reader device

Technical field

The utility model relates to a kind of reader device, especially referring to can be for the reader device of preset memory card grafting in the small USB plug of volume, and have the connectivity port of same widths in the USB plug respectively and can be the electrical memory card module that contacts with memory card, so reach miniaturization Design, simple in structure, can take conveniently, the effect of according with the demands of the market property.

Background technology

Press, the modern science and technology progress also leads many electric equipment productss constantly to innovate, progressive, and progressively enter the digitized epoch, therefore digital sci-tech product is constantly weeded out the old and bring forth the new especially, digital television for example, digital sound, MP3, digital camera, electronic dictionary, PDA or other electronic product etc., and in many digital products, normally rely on memory card to be remembered, access data, upgrade data memory etc., again via calculating punch with the data read of memory card inside or do storage, so for asking use simple and easy, easy to carry, many electric equipment products are just towards gently, thin, short, little direction is done design, the relative internals that also makes must reduced volume, therefore must use by the more small-sized memory card charger product of design.

And at present on the market memory card is roughly specifications such as MMC, CF, SMC, MS, SD, and releases the memory card that many volumes are littler, capacity is bigger successively, as Mini SD, MS Duo, Trans Flash etc.

Stored data in the memory card wherein, then can see through calculating punch reads and is stored in the main frame, because the specification and the form of memory card are numerous, make present calculating punch on the market all be designed to can read the calculating punch of plurality of specifications and form memory card, reaching a decometer sheet reading machine can be for the convenience of plural memory card grafting use, yet, general calculating punch all can only provide SD card equidimension to peg graft and use, when inserting in the slot of calculating punch as microminiature memory card desires such as Trans Flash cards, then must can insert in the slot and use, in the use comparatively inconvenience by larger-size adapter, and cost is higher.

In addition with, calculating punch is a kind of interface between memory card and main frame, the USB jack that sees through main frame can carry out data transmission for calculating punch, the card read function is read by main frame apace via the hot plug mode, yet calculating punch volume on the market is bigger at present, take too much space relatively, and because of volume excessive, the weight of also related raising calculating punch integral body, and calculating punch can't directly be inserted on the main frame USB jack, can only additionally buy the USB line to connect the purpose that can transmit, cause use cost to increase, and cause various disappearance of main frame wire rod on every side.

Be with, how to manage to solve above-mentioned existing disappearance and inconvenience, and develop a kind of tool usb connecting port, can peg graft, and light, thin, short, little reader device for the memory external card, be relevant dealer and desire most ardently the direction place of studying improvement.

Because above-mentioned existing apparatus is not all attained ideal in design, so, utility model designer collects related data, via assessment and consideration in many ways, and being engaged in many years of experience, and, adhere to continuous research improvement creative ideas in line with excelsior spirit in the industry accumulation, at above-mentioned deficiency locate improved again, be to design and develop out the utility model reader device.

Summary of the invention

Fundamental purpose of the present utility model is, a kind of reader device is provided, it is connectivity port and memory card module that USB plug is provided with same widths, and can insert by the USB plug rear for the preset memory card on the memory card module and connect, and be coated with screen iron cover in connectivity port and memory card module, and screen iron cover is offered the hollow slots that can supply the housing location on memory card module surface, and the support division that the screen iron cover both sides extend back is for can support housing both sides Embedded Division, form the USB plug structure of miniaturization with this, and then reach simple in structure, can take conveniently, the effect of according with the demands of the market property.

Secondary objective of the present utility model is, the interior one-body molded conducting terminal group that has of memory card module, and the conducting terminal group is provided with plural number and is the contact site that positive force electrically contacts with memory card, when memory card plugs, can reach the effect that contact is respond well, elastic-restoring force is good.

Another purpose of the present utility model is, the conducting terminal group is provided with downward bending and is the electrical subsides portion that supports that contacts with the memory card module, when memory card contacts with contact site, just can support passing on the memory card module originally down through contact site and elastic arm drive to subsides portion, and then make to the contact condition of subsides portion and memory card module more precisely, really, reach signal simultaneously and transmit more stable effect.

For achieving the above object, the technical solution adopted in the utility model is that it is to include USB plug and the outer shield shell that coats of USB plug that a kind of reader device is provided; Wherein:

Described USB plug the place ahead is provided with the connectivity port of tool USB pattern, and connector side in addition is electrically connected with the memory card module, supply the preset memory card to insert in the memory card module and be electric connection by the USB plug rear, and convex with the location division in memory card module both sides, and the top is positioned with the housing of tool posting port;

Described screen iron cover is for being coated on outside connectivity port and the memory card module, and screen iron cover offers a hollow slots on memory card module surface, and the screen iron cover and arranged on left and right sides is provided with the profile groove with the corresponding embedding in the location division of memory card module.

Its scheme two is, a kind of reader device is provided, it is the connectivity port that is provided with tool USB pattern in USB plug the place ahead, and connector is identical with the memory card module width that other side electrically connects, and the memory card module is electric connection for the preset memory card by the insertion of USB plug rear, and be coated with screen iron cover in connectivity port and memory card module-external, and extanding rearward to memory card module both sides in the connector both sides, screen iron cover is provided with support division.
