Embodiment
For specifying design concept; At first see also Fig. 1; Shown is the traditional USB interface connector, and the left side is the plug of device end, and the right side is the slot of host side; Wherein label 104A and 104B represent the shell of plug and slot respectively, provide as electric signal masked isolation (shielding) to act on.
And the object of the invention; Promptly be that function with storage card and USB interface card reader is integrated into one; Be that storage card itself can directly insert USB interface slot, and the conversion of making signal with computer be connected, make storage card need not the transmission of the data of accomplishing via the CR of a USB interface.
And in order to reach above-mentioned target, at first be to design a connector (connector), though it does not meet the USB connector of industrial standard, compatible and insertion USB slot.Because the thickness of existing various storage cards is all very thin, if the connector of the USB interface specification of the standard of employing then will can't be combined with storage card because of its thickness is too high effectively.Therefore the present invention at first does an improvement to the USB connector of standard.
See also Fig. 2, shown promptly is the connector 100 that the present invention designed, and it comprises a metal terminal group 101, a ridge 102 and a connector body 103.This metal terminal 101 is made up of the number of metal sheet; Its number, distance all are same as standard USB interface connector with dimensions; Connector body 103 then is different from standard USB interface connector; Itself can possess has a ridge 102, is fixedly arranged on connector body 103 both sides respectively, or establishes a ridge 102 in addition on the both sides of connector body 103.The thickness of body 103 then is same as the inner space height of standard USB interface slot, and so design can be inserted in the standard USB interface slot (" h " as shown in Figure 1), and makes signal be able to transmission.And be positioned at the ridge 102 of connector body 103 both sides, and then can prevent to insert the mistake that the signal that causes connects because of turned upside down because of body 103, therefore the thickness of whole connector will be far below the thickness of the USB connector of standard.Basically; Connector body 103 can provide at least one outer grooves (shown in the 102A among Fig. 2); So that be intercalated in standard USB interface, during like the standard USB connector, can strengthening the fastness of joint; And this connector 100 can be directly by welding, it is combined with a printed circuit board (PCB) 201 and makes line conduction.
Compare with Fig. 2 by Fig. 1; Can know that the purpose that Fig. 2 designs is to be to remove shell 104A as shown in Figure 1; And connector 100 height behind the removal shell can significantly reduce; Because the present invention directly designs coupling arrangement 100 on device, so there is not traditional USB connecting line (USBcable); And the effect of former shell is to reduce signal delay (delay) effect of USB connecting line, therefore for the present invention's design, originally can remove as the shell of electric signal buffer action.And utilize the indignant thought of above-mentioned design, can be with USB interface coupling arrangement 104A flattening, and then impel USB interface product to develop towards card-type, further discuss as follows.
See also Fig. 3, shown in Figure 3 for the circuit block diagram of two interface storage cards that the present invention designed.As shown in the figure, this storage card has two digital date transmission interfaces, and one is the application system interface, and another then is the USB interface.When data from applied system; Like digital camera; After being sent to storage card via system connector 150; Data will be stored in the inner reservoir 160, in case after storage card self-application system takes out, promptly the connector 100 of previous designs capable of using is connected with the USB interface of host computer.Just storage card is directly inserted in the USB interface slot of computer, and do not need to see through again USB connecting line and USB interface card reader, just can data be transferred to host computer.Interface controllor 140 wherein, bag have been lifted the function of relevant application system interface and the conversion of USB interface.
See also Fig. 4, shown in Figure 4 is the embodiment of of the present invention pair of interface storage card, as shown in the figure; Can know that after protecting cover 71 puts storage card 70 promptly the storage card size with general is identical, and can be used in the application system; After taking out from system; As long as sheath 71 is taken off, the connection that exposes promptly capable of using is clamored and 72 inserted in the USB interface slots, and is quite convenient in the use.
Therefore, utilize aforesaid connector, can the USB signal directly imported and data is written in the storage card, vice versa.This promptly accomplishes a storage card and has two different interface connectors simultaneously.While is for the security of data; The present invention design is also anti-ly write the outside that read-only (Read Only) switch 73 and a cresset 75 place storage card with one, when switch 73 switches to reading mode, and the function that storage card is only given information and read; And can not data be write in the storage card; In case after switching to normal mode, can normally use the read-write capability of storage card, cresset 75 is then in order to the duty of display device.
If further simplified system design and the application system interface is removed; Keep USB interface system wherein and utilize coupling arrangement of the present invention; Then can derive extra-thin USB interface storage card; See also the USB interface storage card of Fig. 5, with the USB interface memory storage (apparatus) of now standard USB interface connector comparatively speaking, light, thin, short, little more on the volume.
Can learn by Fig. 2 in addition, behind the signal process metal terminal 101 of connector 100,, and be able to get into the reservoir storage device again by the welding of terminal 101 with the metallic conductor (pads) of printed circuit board (PCB) 201.Because the pad of circuit will cause the change of impedance, this transmission to high-speed information will impact.Therefore the further purpose of design of the present invention is that the pad of circuit is removed; So must give up the use pattern of connector; Make signal directly contact the metallic conductor on the printed circuit board (PCB) of reservoir storage device by the USB terminal of host side; And transfer to the reservoir storage device, so can eliminate the pad of circuit.This is that general industry is commonly called as the design concept of so-called " golden finger ", furthermore, is the use of having removed connector, and replaces the connection of the mode of direct contact as circuit, to promote the characteristic electron of reservoir storage device in high-speed transfer.
For further specifying the connectorless design concept, see also Fig. 6, be the plane contact formula coupling arrangement 110 of a tool USB contact jaw; As shown in the figure; This printed circuit board (PCB) 202 is with after a pedestal 113 combines, and it is inner that its whole height can be placed in the USB slot of host side, and the ridge 112 of mistake proofing then design takes shape on the shell 114; And be located at printed circuit board (PCB) 202 both sides, former metal terminal 101 shown in Figure 2 is then with 111 replacements of metallic conductor of layout moulding on the printed circuit board (PCB) 202.Therefore the structure after above-mentioned plane contact formula coupling arrangement 110 combinations will be same as the design of Fig. 2 connector, but remove the use of this connector and the pad of circuit, in the manufacturing production operation of product, also simplify the flow process of assembling.Basically, this pedestal 113 can provide at least one outer grooves (shown in the 112A among Figure 13), so that be intercalated in standard USB interface, during like the standard USB connector, can strengthen the fastness of joint,
See also Fig. 7, be the system block diagrams of USB interface storage card of the present invention, in its system 500, label 501 be printed circuit board (PCB) and on metallic conductor, 502 is the USB controller, 503 is the magazine member array.As stated, signal no longer passes through connector and pad thereof on storage device, and directly is connected in the USB metal terminal of host side via the metallic conductor of layout (layout) on printed circuit board (PCB) and forms the connection of circuit.
USB interface data storage device after the assembling is as shown in Figure 8; Utilize USB interface plane contact formula coupling arrangement of the present invention, can be effectively and significantly reduce the thickness of reservoir storage device, and increase the convenience that it carries; Wherein label 300A part promptly is to utilize the USB interface coupling arrangement of plane contact formula of design concept and the moulding of Fig. 6; Wherein can add and put a cresset 114A in the outside, in order to the duty of indication storage device read-write, 202C one prevents the switch of the data that writes; Can protect data to cover unexpectedly, delete, increase the security of data.
Therefore, by above-mentioned method, the present invention has disclosed the storage device of a new USB interface again, and its thickness is far below the memory apparatus of present use tradition USB connector, and need not use connector and reduced extra pad.
The plane contact formula coupling arrangement that uses USB interface of the present invention is on existing various reservoir storage devices; Utilize it can reach the characteristic of USB interface coupling arrangement height that debases the standard, the another kind of novel reservoir storage device that has two kinds of different interface coupling arrangements simultaneously so can develop.For further elaboration, see also Fig. 9, be one to have an above-mentioned USB interface coupling arrangement and an application system, the system block diagrams of the reservoir storage device of interface coupling arrangements such as memory stick card, SD card, PCMCIA flash card for example.Wherein, System 500A comprises an aforesaid USB plane contact formula coupling arrangement 504, and 505, one of the coupling arrangements of another known application system have the controller 506 of two interface signals conversions; It can convert data the USB signal to and use interface signals, and one group of reservoir array 507.
Be the realization design of the convenient Fig. 9 of argumentation calcspar, the present only lifts with memory stick card and illustrates, and all the other reservoir storage devices are as long as structure is suitable, and the method that can also utilize the present invention to narrate designs.See also Figure 10; It is one to have the side cutaway view of the memorystick card of USB interface coupling arrangement of the present invention; As shown in the figure, wherein label 300 area part frameworks become USB signal contact jaw, provide the signal of USB to read and write; Label 400 area parts then structure become memory stick card (application system) interface end, and it can be different according to the storage card of different size; Reservoir storage device just of the present invention can have two kinds of different interface ends simultaneously; One is USB interface end; The interface that provides conduct to be connected with host computer end signal; Another is then for (for example: MMC, SD, PCMCIA using the interface end ... Deng), the interface that generator is connected with signal between application system.
