Today, SIM cards used in communication devices such as mobile phones vary in size, for example, standard size SIM cards are 25 x 15mm in size and Micro SIM cards are 12 x 15mm in size, whereas Nano SIM cards in question may be 12 x 9mm in size, although the thickness of these cards is substantially the same, being about 0.84 mm.
For example, most mobile phones of today, no matter GSM or 3G, still use a standard size SIM card (hereinafter referred to as a big card), while those of iphone and the like use a Micro SIM card (hereinafter referred to as a small card). Therefore, after purchasing the iphone, the user has to face the situation of replacing the existing large card or cutting the large card into small cards for use. However, once a large card is cut into small cards, it is difficult to use the small cards again as large cards, and various card adapters for converting the small cards into the large cards are on the market, and are sometimes called card conversion covers, card holders, and the like.
A typical card adapter is shown in fig. 1 and generally comprises a frame 10 with a cutout 11 in the middle, wherein the frame 10 has the same outer dimensions as a large card, and the cutout 11 in the middle of the frame 10 is adapted to receive a small card 20. When the small card with the adhesive is used, the chip contact surface of the small card 20 is placed in the hollow part 11 in an upward mode, then a layer of film 30 with the adhesive is pasted on the back surfaces of the small card 20 and the frame 10, and the redundant part of the film 30 is cut off along the periphery of the frame (shown by a dotted line part in the figure), so that the small card 20 can be pasted on the hollow part 11 of the frame 10 through the film 30, and the small card 20 can be restored to be a large card for use. However, the card adapter has a significant disadvantage in that the film 30 for fixing the small card 20 to the hollow portion 11 of the frame 10 is easily separated from the frame 10 during use, and particularly, when the card reduction sleeve is repeatedly inserted into and withdrawn from the SIM card slot many times, the separation is easily caused. Therefore, the card adapter is often used only a few times temporarily, has poor reliability and is not suitable for repeated use.
In addition, the iphone mobile phone is usually provided with a metal card holder, the middle of the card holder is provided with a groove for accommodating a small card, and the bottom of the groove is provided with a supporting edge strip for preventing the small card from falling off. However, as the depth of the groove is equal to the thickness of the small card (0.84 mm), the thickness of the support bar (which is difficult to control within 0.05mm due to metal processing) is added, and the thickness of the whole card holder is much larger than that of the normal SIM card, which causes a problem: the SIM card slot needs to be redesigned to accommodate the thicker card holder, which results in increased cost and poor versatility of the product.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 2 is a perspective view of a card adapter according to an embodiment of the present invention, which is adapted to convert a second card into a first card for use, as shown in the drawings. In the present invention, the first card and the second card belong to a relative concept, for example, if the first card is a standard-sized SIM card, the second card can be an existing Micro SIM card, a Nano SIM card that may appear in the future, or any SIM card of other specification and suitable for conversion. Alternatively, if the first card is an existing Micro SIM card, the second card may be a Nano SIM card that may appear in the future, or any other SIM card of any other standard that is suitable for conversion.
Of course, it will be understood by those skilled in the art that the present invention is not limited to the context of SIM cards, but may also be applied to the conversion of memory cards such as MMC (Multi Media Card) or TF (Trans Flash Card) cards into SD memory cards, for example. Accordingly, what is claimed is an adapter for converting cards of different sizes to cards of a uniform size, wherein the first and second cards involved are merely relative concepts.
For convenience of understanding, the following embodiments take a SIM card as an example, and the structure of the card adapter and the manufacturing method thereof according to the present invention are described in detail. As shown in fig. 2, the card adapter has a UV glue main body portion 1 and an ultraviolet light permeable plastic film 2, the UV glue main body portion 1 has the same peripheral size as the first card and has a recess 3 for accommodating the second card, the plastic film 2 is disposed at the bottom of the recess 3, and the UV glue main body portion 1 and the plastic film 2 are adhered and cured into a whole by ultraviolet light irradiation.
The UV glue main body part 1 is formed by curing UV glue, and the UV glue can be any UV glue which can be cured by ultraviolet light and is bonded with the plastic film 2. The plastic film 2 may be any transparent plastic film, such as a PET (polyethylene terephthalate) plastic film, a polyethylene plastic film, a polypropylene plastic film, a PC (polycarbonate) film, and the like.
Fig. 3 shows a cross-sectional view a-a of fig. 2, in which, although the UV glue main body 1 and the plastic film 2 of fig. 3 are shown as two parts, the UV glue main body 1 and the plastic film 2 of the present invention are integrally bonded and cured by ultraviolet light irradiation, that is, there is no adhesive between the UV glue main body 1 and the plastic film 2, and the frame 10 and the film 30 of the prior art are fixed together by adhesive, so that the structure of the present invention is much stronger than the prior art, and the UV glue main body 1 and the plastic film 2 are hardly separated after being integrally cured.
For a clearer understanding of the present invention, a manufacturing process of the card adapter of the present invention will be described in detail below with reference to fig. 4. Wherein, fig. 4 shows a schematic cross-sectional view of the manufacturing process of the card adapter of the present invention. As shown in fig. 4, first, a mold 100 adapted to the card adapter is provided, and UV paste 1' is injected into the mold 100. To avoid injecting insufficient UV glue 1 ', it is usually necessary to inject more UV glue 1 ', i.e. to make the UV glue 1 ' at least flush with the top surface of the mold 100 or slightly more. Fig. 4 shows a situation where slightly more UV glue 1 'is injected, which normally does not flow freely, due to the larger surface tension of the UV glue 1', and thus does not flow away due to too much injection.
Then, a layer of plastic film 2 which is permeable to ultraviolet light is covered on the top surface of the mold 100, and in order to make the plastic film 2 fit to the UV glue 1 ', a roller 200 is shown at the upper end of the plastic film 2 in the figure, i.e. the plastic film 2 is pressed by the roller 200, and the excess UV glue 1' between the plastic film 2 and the top surface of the mold 100 is pressed, so that the UV glue 1 'is flush with the top surface, and at the same time, the plastic film 2 and the UV glue 1' are completely fit together.
And then irradiating the UV glue 1 'through the plastic film 2 by using ultraviolet light 300 to enable the UV glue 1' and the plastic film 2 to be bonded and cured into a whole. The cured UV glue 1' forms a UV glue body part 1. And finally cutting off the excessive rough edge to obtain the card adapter.
Through the above manufacturing process, those skilled in the art can recognize that since the UV glue main body part 1 and the plastic film 2 constituting the card adapter are adhered together after curing the UV glue, the space between the UV glue main body part 1 and the plastic film 2 can be completely ignored, that is, the thickness of the card adapter of the present invention is equal to the sum of the thicknesses of the UV glue main body part 1 and the plastic film 2, and the thickness of the UV glue main body part 1 is determined by the mold 100, and the plastic film 2 can be a commercially available product with a suitable thickness, so that the manufacturing precision of the card adapter can be easily controlled.
In addition, on one hand, the UV adhesive main body part 1 and the plastic film 2 are very firm after being cured into a whole, and on the other hand, the manufacturing precision is easy to control, so that compared with the prior art, the plastic film 2 with very thin thickness can be selected for the card adapter of the utility model, for example, in a specific embodiment, the thickness of the card adapter of the utility model can be 0.89 mm-0.75 mm; the thickness of the plastic film 2 can be as thin as 0.02 mm-0.15 mm. That is to say, the utility model discloses a card adapter is when using, and after the SIM card that thickness is about 0.8mm was placed in recess 3, the outstanding height of SIM card equals the thickness of SIM card itself plus plastic film 2, then the height that wholly stands out is totally within the acceptable scope for standard SIM card slot, need not redesign SIM card slot, has practiced thrift the cost greatly for equipment manufacturer, and the commonality of product is fine moreover.
If the film 30 is adhered to the frame 10 by other means, such as the adhesion means shown in fig. 1, the height of the card adapter is affected by the type of double-sided adhesive and the adhesion firmness, and the accuracy is difficult to control. In addition, the bonding method is easy to delaminate, not firm enough and difficult to reuse.
If the thickness of the bottom of the groove of the card adapter is difficult to be extremely thin by integral injection molding, and the minimum thickness which can be obtained by the injection molding is usually more than 0.15mm, the thickness of the card adapter manufactured in the mode can exceed the thickness range which can be accepted by a standard SIM card slot, and the card adapter can be easily clamped even if the SIM card slot can be inserted after the SIM card is installed. Similarly, if the card adapter is processed by metal, the thickness of the card adapter as thin as 0.02 mm-0.15 mm is difficult to obtain by the existing process, and even if the card adapter can be made large, the cost is also greatly increased. That is to say, through the metal cutting manufacturing card adapter, the thickness of recess bottom also can not do like the utility model discloses the thickness scope that can reach even if accomplish also to be difficult to bear in the cost, therefore the card adapter that obtains also is that thickness exceeds standard.
Fig. 5 is an exploded perspective view showing another embodiment of the present invention, as shown in the figure, in order to fix the small card in the groove 3 of the card adapter, a layer of double-sided adhesive tape 4 may be provided at the bottom of the groove 3, and the small card may be attached to the card adapter by the double-sided adhesive tape so as not to fall off after being placed in the groove 3. In addition, in order to prevent dust from contaminating the double-sided adhesive tape when the double-sided adhesive tape is shipped, a plastic protective film 5 can be covered on the surface of the double-sided adhesive tape 4. As shown in the figure, the plastic protection film 5 comprises a body part 51 attached with the double-sided adhesive tape 4, and a free end 52 connected with the body part 51 and convenient for a user to tear off the plastic protection film 5.
In addition, referring to fig. 2 and 5, in one embodiment, a slope 21 is provided at the edge of the recess 3 of the card adapter, and the reason for this can be explained as follows: when a small card is placed in the groove 3, a gap exists between the small card and the edge of the groove 3, and when the metal contact in the SIM card slot slides across the surface of the card adapter, the metal contact may be blocked in the gap, so that the card adapter cannot smoothly enter or exit the SIM card slot, and in severe cases, the card adapter is difficult to be taken out of the SIM card slot. Of course, it should be understood by those skilled in the art that the inclined plane disposed at the edge of the groove may be determined according to the direction of inserting the card adapter into the SIM card slot, and may be disposed as shown in fig. 2 and 5, or disposed at the other two sides of the groove, which is not described herein.
The utility model discloses a card adapter is applicable to and converts the second card to first card and uses, its sound construction, and the precision is high, can be applied to current card slot, need not design new card slot, and the commonality is good, low cost.
It is to be understood by those skilled in the art that while the present invention has been described in terms of several embodiments, it is not intended that each embodiment cover a separate embodiment. The description is given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including all technical equivalents which are encompassed by the claims.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention.
