Description

A kind of storage card reader

Technical field

The utility model relates to a kind of card reader, relates in particular to a kind of storage card reader.

Background technology

Store the instrument that card is preserved, shifted as information at present, be widely used in people's daily life, wherein the development trend of mini memory card is also more and more obvious, carries and uses with more convenient people.

In brief, in the known card reader structure, deck 100 is welded on by several metal pins on it and realizes between the two fixing on metal dots of pcb board (electronic circuit board), in the shell of packing into then, at the sheathed USB (universal serial bus) of the interface of this shell (USB) interface.Store card 200 when inserting card reader, the positioning step 101 (consult Fig. 1) of screens 201 clips on deck by storing on the card promptly bears its external force by deck.The card reader of this structure requires the mould of preparation deck and pcb board must have high precision when making, to keep accurate location between the two.Plug repeatedly simultaneously stores card, the as easy as rolling off a log damage that causes deck, and the sealing-off between deck and the pcb board.Therefore (the FPE plastics ABS) are made, and deck is made into shaped as frame, and its cost of manufacture can't descend to adopt higher, the expensive material of hardness.Moreover owing to adopted USB interface, therefore its volume of known card reader is bigger.

The utility model content

The purpose of this utility model is to provide a kind of storage card reader, to overcome the defective that exists in the known technology.

For achieving the above object, the storage card reader that the utility model provides, it comprises:

Store card reader, it comprises:

One bar shaped deck is welded on the circuit face of pcb board, and in the shell of packing into;

The another side interface end of this pcb board is provided with four pins, forms USB interface with shell;

Side in this shell corresponds to screens place that stores the card side, and a shell screens is set.

Described storage card reader, wherein an end of bar shaped deck is provided with a reference column, and the position of relative this reference column is provided with a pilot hole on the pcb board.

By enforcement of the present utility model, have following effect:

When 1) inserting card reader owing to storage card of the present utility model, its stress point changes housing into, therefore not fragile deck.

2) because the utility model is provided with four pins (being commonly called as " golden finger ") at the back side of pcb board, does not need to connect in addition and establish known USB interface, can reduce thickness easy as can.The another side interface end of this pcb board is provided with 4 pins (being commonly called as golden finger) and the direct USB interface of forming of shell, and its thickness only is 1/2nd of generic USB thickness.

Description of drawings

Fig. 2 is a deck synoptic diagram of the present utility model;

Fig. 3 is the shell synoptic diagram that the utility model is provided with the shell screens;

Fig. 4 is the synoptic diagram that the utility model pcb board is provided with four metal pins.

Embodiment

The card reader that the utility model provides sees also Fig. 2 and shown in Figure 3.

Deck 1 of the present utility model is a strip, the number of pins 11 of this deck 1 and the solder joint welding on pcb board 2 circuit face form one, and (pcb board that adopts because of the utility model is a known products, solder joint on it also is a known technology, therefore do not provide the circuit of this pcb board, be not described in detail yet).Rear interface end place at the pcb board that is welded with deck 1 is provided with four metal pins 3, and the circuit on this metal pin 3 and the pcb board electrically connects.

Housing 4 of the present utility model, with be with the known technology difference, one side of housing 4 inside is provided with a shell screens 41, and the position of this housing screens 41 corresponds to when storing card insertion card reader, stores screens place (consulting 201 among Fig. 1 b) of card side.When inserting the storage card, its deck 1 does not bear and stores the thrust of blocking when inserting, but bears this thrust by shell screens 41.By this structure, 1 of deck plays the effect that contact stores card, thereby protection deck 1 can not be subjected to the damage of external force.

During installation, the pcb board that is welded with deck 1 is packed in the housing 4 of card reader by known technology, the one side that is provided with four metal pins 3 is exposed to the outside of housing 4, can directly be inserted in the USB port of computing machine.

For strip deck 1 being positioned on the pcb board 2 exactly, so that deck pin 11 is welded on the pcb board, end at strip deck 1 is provided with a reference column 12, the corresponding pilot hole (because of the visual angle relation, not drawing among the figure) that also is provided with on pcb board.

Because the card reader that the utility model provides, when inserting the storage card, its deck 1 does not bear the thrust when storing the card insertion, therefore do not need deck to be made shaped as frame can bear bigger thrust as known technology, also needn't select the material that hardness is strong and price is expensive, and also be prolonged serviceable life.The utility model can adopt general Polyvinylchloride (PVC) material deck.

Simultaneously,, make the utility model volume thin little, light and handy, be more suitable in carrying owing to saved the USB interface of known technology.

Claims (2)

1. one kind stores card reader, it is characterized in that, comprising:

One bar shaped deck is welded on the circuit face of pcb board, and in the shell of packing into;

The another side interface end of this pcb board is provided with four pins, forms USB interface with shell;

Side in this shell corresponds to screens place that stores the card side, and a shell screens is set.

2. storage card reader as claimed in claim 1 is characterized in that, an end of described bar shaped deck is provided with a reference column, and the position of relative this reference column is provided with a pilot hole on the pcb board.
