DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The FIG. 1 of the structure illustrative view for one preferred embodiment of the present invention is referred in association with other figures; As shown in the figures, the present invention mainly comprises a card body 1 and a separable block 2, wherein,
The card body 1, master card, which being made of thermoplastic resin through extrusion molding and packaging, has a chip module 10 mounted on the substrate as well as the memory card specification and a set of exposed I/O contacts 13 of said chip module disposed at one end of said card body 1 (please refer to the FIG. 2); The specifications of the memory card can be anyone miniature card of Secure Digital Card, Multi Media Card, MS Pro Card series, XD Card, Mini SD and so forth; A right angled cut recess 12, which being formed at the other end of said card body 1 has an indented (second insertion slot 121 and a snap buckle 122 for hooking up with the separable block 2 respectively disposed on each of both sides forming the right angle in said cut recess 12; Other than said cut recess 12, the rest part of said card body 1, which conforming to the size of the universal serial bus (USB), has a pair of horizontal parallel indented first insertion slots 11 and 11′ are transversely juxtaposed on one surface of said card body 1 as well as has a set of I/O contacts 14 of the universal serial bus (USB) formed on the inverted surface said card body 1 (please refer to FIGS. 2 and 3);
The separable block 2, sub-card, whose shape conforming to the outline of said cut recess 12 on said card body 1, has a protruded second fastener 22 and a snap buckle 23 for coupling with the corresponding said indented second insertion slot 121 and snap buckle 122 on said cut recess 12 of said card body 1 respectively disposed on each of both sides forming the right angle in said separable block 2 as well as has a pair of horizontal parallel indented first fasteners 21 and 21′ juxtaposed on one surface of said separable block 2 for coupling with the corresponding said pair of first insertion slots 11 and 11′ on said card body 1; Wherein, said pair of juxtaposed first fasteners 21 and 21′ and pair of first insertion slots |11 and 11′ can be contrived as either stout-one with slim-one set manner or slim-one with stout-one set manner in different specifications so as to avoid happening of wrong action due to incorrect inserting direction by the user; Besides, said pair of juxtaposed first fasteners 21 and 21′ can also be arranged in anyone manner of both-in-same-direction, back-to-back-direct-outward and face-to-face-direct-inward, while the face-to-face-direct-inward arrangement manner is adopted in the exemplary embodiment; Moreover, the total thickness t of said separable block 2 plus said pair of first fasteners 21 and 21′ on which must be not greater than the thickness T of said card body 1 so as to avoid said separable block 2 being higher than said card body 1 upon completion of assembly (please refer to the FIG. 4); Thus, both of the failure in inserting said adapter card into the connector of related electric device due to whose bulge and the damage of the conducting terminal in the connector can be prevented.
During practical use, both of said card body 1 and separable block 2 are assembled into an integral unit of finished adapter card (please refer to the FIG. 5); Said separable block 2, if which being dismounted from said card body 1 (please refer to the FIG. 6), can be stacking mounted on the top of said card body 1 by means of sliding said whose first fasteners 21 and 21′ into said first insertion slots 11 and 11′ on said card body (please refer to the FIG. 7); Thereby, for the attached card of thin-type such as Mini SD, not only its thickness can meet that of the USB port but also the risk of loss and dropping off can be avoid; Meanwhile, by means of the arrangement of said pair of first insertion slots 11 and 11′ on said card body 1 together with said pair of first fasteners 21 and 21′ on said separable block 2, said separable block 2 cab be precisely positioned and locked in the predetermined destination on said card body |1 with braking function of anti-idle ability so as to prevent such product from failure of normal function due to mistake and inadvertence from the user. Certainly, if the thickness of the suitable card meet that of specification for inserted USB port such as Secure Digital Card, XD Card and so forth, the adapter card can be directly used for insertion by just pulling out and removing said separable block away from said card body 1 without necessity of stacking and mounting it on said card body 1; Thereby, the dual interface of memory card specification and the USB specification is finished.
The difference of the structure illustrative view for other preferred embodiment of the present invention in the FIG. 8 from above exemplary embodiment aforesaid is that an additional notch 15 being created on the edge of said card body 1 as well as an additional jut 24 being created at the corresponding edge of said separable block 2; By means of both said additional notch 15 and jut 24, said separable block 2 cab further be precisely positioned and locked in the predetermined destination on said card body 1 with braking function of anti-idle ability so as to prevent such product from failure of normal function due to mistake and inadvertence from the user; As for other structure and assembling way, they are the same as those in the above exemplary embodiment aforesaid in no need of redundant description here.
The FIG. 9 is the flow chart of the fabricating process for one preferred embodiment of the present invention. In order to keep the sliding successful smooth and precision in assembly and dismounting of said card body 1 and separable block 2, the plastics material used in said card body 1 and separable block 2 of the present invention is elastic thermoplastic resin with fabricating process is described below in association with the FIG. 9 attached:
First, cut and trim the PCB (printed circuit board); Secondly, dispose and arrange some chip modules, which comprises IC components of passive component, memory and so forth as well as I/O contacts for signal connection; Thirdly, fix and package chip the modules of IC component by thermosetting resin; Owing to employing thermosetting resin as packaging material, the production speed is increased with firmness so that not only the steady package can be effectively achieved but also the product yield can be promoted; Fourthly, enwrap and form shape of the card frame covering the modules of IC component aforesaid by the extrusion molding of the thermoplastic soft resin such as TPE, TPU, TPR and so on with only exposure of the I/O contacts for data and information connection so that the dual interface card shape of the memory card and the universal serial bus (USB) is finished; Meanwhile, form the shape of the separated block by the extrusion molding of the thermoplastic resin; Owing to the elasticity of the thermoplastic resin in forming the external shell, the adapter card is not only difficult to fracture under pressure but also easy to couple and assemble each other mutually; Finally, assemble both of the card body and the separated block into finished integral adapter card.
The difference of the flow chart of the fabricating process for other preferred embodiment of the present invention in the FIG. 10 from that of the above exemplary embodiment aforesaid is in eliminating and simplifying the fixing and packaging process in third step by directly packaging and forming the card shape by the extrusion molding of the thermoplastic resin.
From the above description, it is known that the feature of the extrusion molding of the thermosetting and thermoplastic resin is amply developed by the present invention so that not only the fabricated adapter card has the advantage of thermosetting and thermoplastic resin but also the production quantity and quality can be increased; Especially, the particular contrivance of the present invention can be coordinately used in the industrial application, which has never disclosed publicly; Thus, the present invention conforms to the essential patent requirement and criterion of novelty and non-obviousness stipulated in the patent laws.
Accordingly, we submit the present invention for patent application in new type; please favor us by granting award of patent, which will be greatly appreciated by us.
However, all the disclosure and description mentioned above, which is only for the preferred exemplary embodiments of the present invention, is not to be used to limit the range of the present invention; Any simple and equivalent change, alteration, adjustment and modification within the scope of the claims of the present invention is implied being covered by the range of the present invention.
