Embodiment
In order to be described in more detail the present invention, will cooperate following examples and accompanying drawing to be described in detail.
The invention relates to a kind of USB interface and store card, be meant a kind of any electronic installations that need storing media such as personal computer, digital camera picture device, digital mobile apparatus that can be applicable to especially.
See also Fig. 2, Fig. 3 and shown in Figure 4, it is overall appearance view, side view and backplan that USB interface of the present invention stores card in regular turn.USB interface of the present invention stores card 20 and comprises a card form housing 22; Have a switch 24 on the card form housing 22, to be used for the setting of Write-protection prevention, person more, described switch 24 can be a concealed design, and just switch there is no and protrudes in outside the card form housing 22; Card form housing 22 bottoms have an opening 26; And edge is provided with locating groove 28 around the card form housing 22; One is positioned at the circuit board 30 (as shown in Figure 3) of card form housing 22, adopt direct layout on the described circuit board 30 to form a plane formula usb interface unit 32 in order to be connected with an electronic installation, described plane formula usb interface unit 32 manifests from this opening 26, and the mode of described direct layout can effectively be saved the production cost of known usb interface unit.
The outward appearance of plane formula usb interface unit 32 of the present invention presents five concentric circles as shown in Figure 4, and it is GND, D+, D-, VBUS and ID contact from outside to inside in regular turn.Described electronic installation can be any products that need storage device such as a portable electronic devices, digital camera, computer installation or mobile computer device.
See also shown in Figure 5ly, be integrated with a mnemon 34 on the described circuit board 30, described mnemon 34 can be non-volatile note body or fast flash memory bank; One microcontroller 36 in order to the read-write of control mnemon, so that data can write this mnemon 34 by this electronic installation 38, or transferring the USB/OTG serial interfaces engine 40 of electrical signal to described electronic installation 38 and in order to data with described microcontroller by described mnemon 34 data of reading, described USB/OTG serial interfaces engine 40 also can be integrated in the microcontroller 36.
See also Fig. 6, it inserts the embodiment synoptic diagram of an electronic installation 38 for the present invention 20, directly be in the layout of usb interface unit 32 circuit board 30 on because the present invention adopts this moment, form the usb interface unit 32 of a plane formula, therefore when using USB interface storage card 20 of the present invention to store data, can insert the slot 42 of a corresponding specification of electronic installation 38 fully, to carry out the access of data, do not protrude in the outer disappearance of electronic installation and do not have known USB interface storage device, so use electronic installation of the present invention can have move mode more freely, do not protrude in the scruple that electronic installation produces collision outward or influences the electronic installation global design and do not have, more the person is because usb interface unit of the present invention 32 and nondirectional restriction, therefore data access is carried out in the present invention being inserted with any direction that the user can not limited in the electronic installation 38, and the four directions can effectively prolong serviceable life of the present invention to the design that contact is all arranged.
On this electronic installation 38, can see through the access action that several electroconductive elastic sheets 46 that are arranged on corresponding flat formula usb interface unit 32 on the circuit board 44 carry out data in memory body or the electronic installation.See also Fig. 7, USB interface of the present invention stores another embodiment of card, this embodiment and the main difference of previous described embodiment are to present five concentrically ringed plane formula usb interface units and change to the plane formula usb interface unit 48 that presents golden finger type that is divided into card form housing 22 surroundings aforementioned, and former opening 26 in order to expose five concentrically ringed plane formula usb interface units, for cooperation exposes golden finger type usb interface unit 48, and be modified to the opening 50 that is arranged at card form housing 22 surroundings as shown in the figure in the lump.And golden finger type usb interface unit 48 is GND, D+, D-, ID, VBUS in regular turn.
In sum, the present invention is that a kind of USB interface stores card, its usb interface unit is used on the circuit board directly, and layout forms, effectively avoid commonly used with this its because of the excessive shortcoming that can't insert electronic installation inside of usb interface unit, and this usb interface unit generation type can effectively be saved the cost of processing procedure, and reduce the volume that USB interface stores card significantly, increase its portability and life-span, and make portable electronic product use USB interface to store when blocking, can possess its good mobility.
The above only is preferred embodiment of the present invention, so the equalization of doing according to the described shape of the present patent application claim, structure, feature and spirit changes and modifies such as, all should be included in the claim of the present invention.
