Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
The storage card that comprises two kinds of standard contact elements provided by the invention, first embodiment as shown in Figure 1, storage card 100 comprises two kinds of standard contact elements that interconnect and be set to one, two kinds of standard contact elements are arranged at the two ends of described storage card respectively, the width of one of them standard contact elements is big, and the width of another one standard contact elements is little.The agreement difference that two kinds of standard contact elements of the present invention are observed, the wide standard contact piece of preferred described storage card 100 upper ends is set to observe the SD standard contact elements 110 of safe digital card standard, and the little standard contact elements of described storage card 100 lower end width is set to observe the USB standard contact elements 120 of universal serial bus standard.
Under the prior art, storage card 100 is the storage device of low thickness, and USB standard contact elements 120 is the standard contact elements of low thickness, and the height of the USB standard contact elements of low thickness is about 2.2mm under the prior art, and the height of USB slot is between 2.5mm-3.2mm; The height of SD slot containing cavity is between 2.42mm-2.46 under the prior art.And the standard contact elements of low thickness is in slot, and the elastic component by the upper and lower surface of slot inwall engages and is fixed in the slot.The slot inwall generally is provided with two parallel elastic components respectively and engages standard contact elements on upper and lower surface.
The standard contact elements 110 that the described width of the present invention is little is provided with stop part 130 with the metal terminal facing surfaces, to increase the height of described storage card 100.The length of described storage card 110, with comparing with the length of the containing cavity of the suitable slot of described wide standard contact piece 110, the former is greater than the latter.Described storage card 100 inserts the slot suitable with described wide standard contact piece 110, and the standard contact elements 120 that described width is little has an exposed parts; Described stop part 130 is arranged on the exposed parts on the little standard contact elements of described width, as shown in Figure 1.Described stop part 130 increases the height of described storage card 100, and the USB standard contact elements 120 that the described low thickness of assurance is set of described stop part 130 can insert described USB slot; Described SD standard contact elements 110 can insert described SD slot simultaneously, and just storage card 100 can insert described SD slot; And because the setting of described stop part 130, making the height of described USB standard contact elements 110 be higher than the height of described SD slot containing cavity, described USB standard contact elements 110 can't insert described SD slot.
The present invention preferably is set to a strip rectangle with described stop part 130, and the height of described stop part 130 has upper and lower two surfaces of metal terminal perpendicular to described USB standard contact elements 120.Described stop part 130 preferred height are between 0.3+0.03mm to 0.3-0.01mm.The height of described USB standard contact elements 110 can be between 2.5+0.03mm to 2.5-0.01mm; The height that preferably can make described stop part 130 is 0.3mm, and the height of USB standard contact elements 110 is 2.5mm.
Storage card with two kinds of standard contact elements of the present invention, its second embodiment, storage card 200 is as shown in Figure 2.Described storage card 200 is with the difference of storage card 100, is provided with two and cuts off the district on described stop part, and promptly first cuts off the 131 and second partition district 132, district.The upper and lower surface of USB slot inwall is provided with two elastic components respectively and is used to engage the USB standard contact elements under the prior art.It is corresponding with two elastic components on the USB slot inwall that the described first partition district 131 and second cuts off district 132, as shown in Figure 3, when preventing that described USB standard contact elements 110 from transfering in the USB slot, described stop part 130 because of and USB slot inwall on the engaging of two elastic components, and described USB standard contact elements 110 is transferred to more easily in described USB slot.
Storage card with two kinds of standard contact elements of the present invention, its 3rd embodiment, promptly storage card 300, as shown in Figure 4 and Figure 5.The difference of described storage card 300 and storage card 100 is, the cross section of described storage card stop part 140 is trapezoidal, has a hypotenuse, and described hypotenuse is at close described SD standard contact elements one end, the height setting of described stop part is identical with described stop part 130, repeats no more here.Described stop part 140 has an inclined-plane, make described USB standard contact elements 110 insert described USB slot after, break away from the engaging of described USB slot inwall elastic component easily, described USB standard contact elements 110 is extracted in described USB slot easily.The cross section of described stop part 140 can also preferably be set to right-angled trapezium, and described hypotenuse also is near described SD standard contact elements one end, as shown in Figure 5.
The storage card that comprises two kinds of standard contact elements provided by the invention has increased the thickness of storage card; Guaranteeing that the little standard contact elements of described width can be inserted in the suitable slot of the little standard contact elements of width, when described wide standard contact piece can be inserted in the slot adaptive with it, the standard contact elements that described width is little can not insert the slot suitable with wide standard contact piece owing to highly increasing; Play and prevent that the little standard contact angle error of the described width of user from going into the slot suitable with wide standard contact piece; thereby damage described and the suitable slot of wide standard contact piece, protection has the digital equipment with the suitable slot of wide standard contact piece.
Should be understood that above-mentioned statement at preferred embodiment of the present invention is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
