The electrical contacts and the configuration of the at least one pre-formed fold line are combined with various cutting lines as described below such that when the body is folded along the at least one pre-formed fold line, the first region and the second region of the body 1 are formed A plug configuration sized to be inserted into a USB receptacle, wherein the electrical contact 14 is positioned to contact the electrical contact of the shackle and the resilient springback of the second region returning to the flat state of the device is electrically contacted Contact force of the contact of the USB socket. Before describing the features of the present invention in more detail, it is helpful to define the terms used in the specification and claims. First of all, reference, the main reason for opening the y. In this context, the phrase ", generally rectangular" is used to: any shape in which the trowel is delimited by the edge of the rectangle, and wherein no plug portion or other element protrudes significantly beyond the boundary of the perimeter rectangle. The term includes the following cases: the corners of the card are pointed or rounded to various degrees, or the edges of the common, ^ edges are not aligned to the extent that they do not interfere with the overall visual impression of the rectangular card. > 'State. In this context, the word, flat is used to mean a configuration in which the foot is flattened to allow insertion into a credit card or the like. It is intended that the nature of the flexible plastic material of the present invention is such that there may be some degree of residual deformation, especially after repeated folding and unfolding of the card. Even in such cases, the unfolded state is referred to as a "flat" state. Reference is made to the electronic circuit 12 contained in the card. This electronic circuit can be known to be included in a mail, smart card, identity tag or USB peripheral device. Any electronic circuit. Preferred examples include, but are not limited to, flash memory chips.

Similarly, the content stored on the wafer may be any storage content suitable for a particular intended application, as will be apparent to those skilled in the art. It should be noted that the thickness of the body i 0 does not have to be uniform throughout the entire range of the card. Commenting on the implementation of thin, the embedded wafer typically has a thickness of about 0, mm which causes the corresponding area of the card to become significantly thicker. The thickness of the reference card device 'this should be regarded as the thickness of the electrical contact area, the pass f corresponds to the thickness of the majority of the knife of the card' and does not take into account the increase in any local thickness in other areas of the card. 0 now specifically to Figure 1A and The implementation of Figure 1B, in this case, the body ι includes two parallel cuts, % on opposite sides of the region 16, which define the edge of the plug configuration also corresponding to the insertion direction of the device. The length of the cut portions 24 and 26 is preferably between about 50% and about 9% of the length of the main body (longer dimension). The electronic circuit 12 is generally defined within the space between the cutting lines. In this embodiment, the preformed slot line 18 extends between the cutting portions 24, 26 and generally perpendicular to the cutting portions 24, 26, thereby defining a fold back. The second region 28' provides the elastic force that will contact the contact to the (four) socket. The resulting plug configuration is best seen in Figure 1B, where zones 16 and 28 form an elastic "v" shaped plug set on either side of the fold line u 123745.doc 200828687, ή: IU ^ ^, heart as viewed from the side . In this case, the second ^ ^ _ is long enough so that the end of the 苴 is still outside the socket during the engagement, so that it is easy to remove the detachment from the socket after use. In some alternative embodiments, the straw is reinforced by the use of a shorter second region 28 (inserted, all located in the USB plug) to enhance the engagement of the plug configuration in the socket. Depending on the situation, the additional use of the first region 16, the outer peripheral surface of the guest and/or the second region 28

The surface may be provided with a conductive contact surface that is now deployed to contact the shield of the USB receptacle and to provide electrical grounding of the device. The plug configuration is shown here to be inserted into a relatively thin host such as a notebook, PDA or cellular phone (10). Since the main body of the main body is relatively thin, the main body 1 〇 心 调*30, 32 (effectively engaged with the engagement with the socket) preferably deflects upward and leans against the upper corner of the host device, thereby providing a contact for the contact 14 Some additional elastic spring pressure on the socket contact. It will be noted that the card devices described herein can be used for a wide range of possible applications' and can include a series of additional features required by their applications. As a non-limiting example, the card device described herein is an "identity certificate" which includes various printed information such as identity photo 7 公司, company logo =, serial number 74 and/or name and card authority holder redundancy. Other details. Depending on the situation, instructions 78 can also be printed on the front or back surface of the device. Alternatively or other 'the card device can include - magnetic strip, RF interrogator wafer " Any other internal or external features in the device. 123745.doc 12- 200828687 Other possible uses of the card device of the present invention include (but are not limited to) · ordinary business cards carrying electronic data; all types of identification cards; credit cards; smart cards And other memory cards. Figures 2A and 2B show a variation of the embodiment of Figures 1A and 1B that is suitable for use with a host such as a desktop computer 104, wherein the USB receptacle 100 is typically disposed away from the host edge The relatively large surface. To prevent the side panels 30 and 32 from interfering with the engagement of the device in the USB receptacle, each blade preferably has an additional pre-formed fold line 34 to allow for folding each At least one of the knives is moved away from the area of the plug configuration. The folded configuration is shown in Figure 2b. In all other aspects, the embodiment of Figures 2A and 2B is similar to Figure 1A and Figure Embodiment of 1B. The additional printing information shown in Figure a has been omitted in view of the clarity of the description. Figure 3 shows another variation in which a single cutting portion 24 is used in conjunction with a portion of the peripheral edge of the body 1 and the cutting portion 24 is used. Parallel to the portion of the peripheral edge of the body 1〇 to define the edge of the plug configuration. In this case, the sheet 3〇 is enlarged and has no first sheet. In use, the side view of this embodiment is identical to that shown in Figure 2B. Similarly, the end of the strip constituting the plug configuration may consist of a second edge of the body 1 shown, or an additional cut (not shown) parallel to the cut 24. In other aspects, this implementation The structure and function of the example are similar to the embodiment of Fig. 1A and Fig. 1B. In the embodiment of Fig. 1A to Fig. 3, the strip of the thin cup 1 z ^ , and the main body 10 of the plug configuration extends to the main body. The outer part of the outer part. It is all 1 knife. It can be connected to many applications. Subject to 'but in some cases it may be better to ensure that the subject is contiguous with an unbroken edge, which may be better. This is similar to inserting the device into a slot or credit card skin loss or 123745.doc 200828687 In the case where ^ ai is dry and concave, it may be particularly advantageous since any cutting portion extending to the edge of the second edge may hit the edge of the pocket during insertion and the connection may retreat from the peripheral edge of the device. The positioning also provides greater protection for the mechanical damage to the connector and makes the entire card less susceptible to damage. An example of two such embodiments is illustrated in Figures 4A through 5B. 4A and 4B, which show another embodiment of the present invention in which the parallel cuts 24 and 26 do not traverse the perimeter of the generally rectangular body. Λ As a result, the third cutting portion 36, which is generally perpendicular to the cutting portions 24 and 26, joins the ends of the cutting portions such that they collectively define a plug forming region in which one of the bodies is inserted from the periphery of the generally rectangular body. In this case, the second region 28 is defined by the space between the fold line 18 and the cut portion %. Here, the fold line % is used to fold down & the integral "U" shaped area W' of the card 10 around the plug such that the strip itself acts in a manner substantially similar to that of Figures 2A and (9). In other aspects, the embodiments of Figures 4A and 4B are similar in structure and function to the structure and function of the prior embodiments. (j (d) to Figure and Figure 56' are diagrams showing another embodiment of the present invention, $ The middle parallel cutting portions 24 and 26 do not traverse the periphery of the generally rectangular body. In this case, the central strip between the cutting portions and the side strips other than the cutting portion, I are folded in the opposite direction, the center strip Up, while the side strips are down, to the scissor-like folded configuration shown in 'Pole® 5B. To achieve this formation, the body 10 is formed with an additional three fold lines along each outer edge, except for the fold line 18. 'You can use only the inner-outer edge, the line and add a - fold line at each end of the center strip to achieve a similar effect. In all other aspects, the structure and operation of the Figure 5 and Figure 5 embodiments are similar. The structures of the aforementioned embodiments 123745.doc -14- 200828687 and In addition, regarding the 彳 立 立 ^ ^ ^ , , , , , , , , , , , , , , , , , , , , , 庄 , 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄 庄The cutting section is two Η, and the 兮 保 在 在 在 1 1 1 1 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造The card is used to connect the useful tamper-proof indication of the application. Card 2 is now transferred to Figures 6A-7B, in contrast to the previous embodiment in which at least the strip of pre-formed fold lines extends perpendicular to the direction of insertion, such embodiments will illustrate at least one pre- An example in which the shaped fold line extends generally parallel to the direction of insertion. Thus, 'first referring to Figures 6 and 6B', these figures show that the body (10) features the implementation of two pre-formed fold lines 42 and 44, which are defined when the stack is folded The edge of the plug configuration. In the example shown here, the 'body 1' is provided with one or more outer fold lines 46'. The fold line is preferably substantially parallel to the fold lines 42 and 44 to allow the body 10 to be folded as a whole - the plug set State 'better not to use any cutting This folded plug configuration is shown end-to-end and enlarged in Figure 6B. It will be appreciated that this embodiment is particularly suitable for thin implementations and is optimal if the thickness of the body 1〇 is not greater than 〇·2 mm. 7A and 7B illustrate yet another embodiment in which the edges of the plug configuration are defined by fold lines 42 and 44. In this case, each fold line has a corresponding second region 48 and 50, respectively, which are folded over the first region. Below the 16 is a spring element formed on the female side of the plug set. A pair of cutting lines 5 2 and 5 4 depict the outer edges of the regions 48 and 50. A small second cutting portion 56 is also typically required to 123745.doc •15- 200828687 Freely fold areas 48 and 50. Figure 7B shows an enlarged end view of the plug configuration inserted into the usb socket. In view of the simplicity of the description, the side panel folded back is omitted in Figure (7). As before, the plug configuration can be formed at the center of the card device, $ is formed at the center of the card, and one of the cards can be used - one of the edges instead of the cutting line. Turning now to Figures 8A-8C, although the embodiments of the invention described so far include a fold in the body 1〇, it should be noted that the distributed deflection of the body in a large area of f) is achieved. It is possible to contact 14 similar to the flexible flexure system that is in contact with the USB socket. This is especially true when the deflection mostly occurs outside the socket. An example of such an embodiment herein is shown in Figures 8A through 8C. In particular, Figure 8A shows a card device in which the body 1 has two parallel cut lines 24 and 26 defining a plug-forming strip in which the electronics 12 and contacts 14 are located. In this case, a localized polyline is not provided. As a matter of fact, the insertion of the plug-forming strip into the USB socket is achieved simply by flexing the center strip upwardly into a plane different from the adjacent sheets, as illustrated in Figures 8B and 8C. Here the elasticity of the material of the card means acts as an external spring which tends to return a portion of the card means to its coplanar starting position. As shown, the resulting downward force on the outer edge 106' of the lower portion of the socket 100 tends to create a ballast effect on the tip end portion of the inserted strip, thereby pressing the contact 14 against the corresponding socket contact. It will be appreciated that the various techniques required to practice the foregoing embodiments of the invention and variations thereof are well known in the art.
