The one USB guide plate that conducts electricity, corresponding superimposed on the extension platform of aforementioned storage card circuit board, its bottom surface system forms a plurality of conductive junction points and is contacted with aforementioned USB conductiving point with correspondence, and its outside surface promptly is formed with the USB interface contact, wherein, this USB USB interface contact of the corresponding separately conducting outside surface of conductive junction point on the guide plate that conducts electricity;

One loam cake, correspondence is incorporated on this base plate, and so as to fixing aforementioned storage card circuit board and USB circuit board, this loam cake one side forms Openworks shape corresponding to the SD interface contact place of storage card circuit board, on the rectangular platform with respect to other side base plate, the place also forms Openworks shape in corresponding USB interface contact;

One bonnet, its bottom surface forms a breach to rectangular flat place that should base plate, can corresponding be sheathed on sealing frame portion and rectangular platform after combination.

The beneficial effects of the utility model are: by above-mentioned structure, when the storage card circuit board was bonded on the base plate, its whole height can meet the standard specification of SD connectivity port, made SD interface contact and the corresponding contact of conducting terminal in the SD connectivity port; Moreover, conduct electricity guide plate on this extension platform by superimposed USB, it is highly required also to make this USB interface contact place can meet the desired 1.8mm of usb connecting port requirement.

Embodiment

See also shown in Figure 1ly, the utlity model has the SD storage card of USB interface, include:

One base plate 10, system extends a rectangular platform 11 by a laminar body one side that is square and is main body, be formed with sealing bead 12 at periphery again around base plate 10, make this base plate 10 whole flat ware structures that form, on the inner surface at aforementioned rectangular platform 11 proximal end edges, form multiple tracks support bar 13;

One storage card circuit board 20, its profile system imitates aforementioned base plate 10 and makes, the outstanding formation one in rectangular platform 11 places of corresponding aforementioned base plate 10 is provided with the extension platform 21 of USB conductiving point 22, but the undersized of global storage card circuit board 20 to be arranged at its inside fully, forms the SD interface contact 23 that meet SD memory card specifications with respect to aforementioned extension platform 21 other ends surface in base plate 10;

The one USB guide plate 30 that conducts electricity, the corresponding aforementioned extension platform 11 of its size dimension, it is a two-sided micro-circuit board that all is formed with conductive junction point, formed four conductive junction point 31 correspondences in its bottom surface are contacted with the USB conductiving point 22 on this extension platform 11, and its upper surface promptly is formed with the USB interface contact 32 (as shown in Figure 2) of four road longitudinal, wherein, the USB interface contact 32 of the corresponding separately conducting outer surface of conductive junction point 31 on the aforementioned medial surface;

One loam cake 40, correspondence is incorporated on this base plate 10 with fixing aforementioned storage card circuit board 20 and USB circuit board 30, these loam cake 40 1 sides form a mullion structure with a plurality of parallel ribs 41, the hollow out space that forms between the two adjacent ribs 41 also forms the sealing frame portion 42 of a hollow out corresponding to the SD interface contact 23 on the storage card circuit board 20 with respect to the rib opposite side;

One bonnet 50, its bottom surface forms a breach 51 to rectangular platform 11 places that should base plate 10;

The assembling mode of aforementioned each element is as the back: this USB guide plate 30 that conducts electricity is superimposed on the extension platform 21 of this storage card circuit board 20, make four conductive junction point 31 correspondences of its bottom surface be contacted with USB conductiving point 22 on this extension platform 11, this storage card circuit board 20 and the USB guide plate that conducts electricity is arranged on the base plate 10 more in the lump, and then this loam cake 40 is that correspondence covers at base plate 10.

As shown in Figure 2, be formed with the palisade portion and the sealing frame portion 42 of hollow out because of aforementioned loam cake 40 front and back ends, so aforementioned SD interface contact 23 all presents the state of exposing with USB interface contact 32, make the storage card corresponding inserted when a SD or usb connecting port, the conducting terminal in the connectivity port can with those contact 32 corresponding contacts on the card; Moreover shown in drawing, after the aforementioned components assembling finished, this a storage card wherein side promptly formed a USB joint.As shown in Figure 3, what this must emphasize a bit is that the SD storage card that overall dimensions meets standard requirements can directly be inserted in the SD connectivity port after bonnet 50 correspondences are sheathed on this USB joint, and when the user desires to use this USB interface, again bonnet 50 removals are got final product.

See also shown in Fig. 4,5, when aforementioned storage card circuit board 20 was bonded on the base plate 10, its whole height was 1.4 ± 0.1mm, and to meet the standard specification of SD connectivity port, so this SD interface contact could corresponding contact with the conducting terminal in the connectivity port; But the 1.8mm that so highly still is not inconsistent usb connecting port is highly required, for solving this problem, the utility model promptly remedies this difference in height distance by stacking the USB guide plate 30 that conducts electricity, make the contact place of USB connector portions also can meet usb connecting port and require requiredly, the support bar 13 on the base plate 10 also can provide a upper setting force amount to give this extension platform 21 and the USB guide plate 30 that conducts electricity simultaneously.

In sum, the utility model can be integrated the SD interface and the USB interface of various criterion specification simultaneously in single storage card, provide more various practicality to select to give the consumer, is a novel good creation really, under the prerequisite that meets the utility model patent requirement, spy's mere formality in accordance with the law files an application.
