The present invention relates to a connection plug. More particularly, the present invention relates to a plug, which can be connected to a receptacle of universal series Bus (USB) receptacle or a USB plug.
As the semiconductor fabrication technology has been developed day by day, the functional of the computer is much powerful and is much better than the first computer, which had ever been made. The operation speed and the storage capacity have been tremendously improved but the computer volume has been reduced a lot.
When the semiconductor fabrication technology has been extremely developed and the network technology has been developed being popular, the current computer has been not only the definition of computer in the early stage. The compute now can be connected with the other computer in any place of the world via the network, so as to transmit and receive any type of information. Also and, the current computer can process a large amount of multiple media information. In order to conveniently transmit, receive and store various kinds of information, the peripheral devices of the computer system have enormous varieties. In inputting devices includes, for example, keyboard, mouse, scanner, or digital camera, and the outputting devices includes, for example, displaying device, printer, or other kinds of storage devices. New devices are continuously developed, according to the needs from the user. In order to allow these kinds of peripheral devices to communicate with computer, various kinds of input/output (I/O) interface standard have been proposed, in which one of the most common standards is the universal series Bus (USB) standard, in which one of the most common standards is the IEEE 1394 communication standard. The USB standard defines transmitting format and speed of information when the USB peripheral device is transmitting information with the computer each other. In addition, the appearance and specification for the plug, receptacle, and the cable connected between, which have been implemented on the peripheral device and the computer, have also been defined, and the same in the IEEE 1394 standard. In the USB standard, it includes the specification for the plug and the receptacle with respect to the series A, series B, series Mini-A, series Mini-B, and so on. Wherein, the series A, series Mini-A, and series Mini-B and mini IEEE 1394 are designed to arrange a set of metal connection terminals of the plug to be disposed on a plane of a holder, as well as the series B is designed to arrange a set of metal connection terminals to be disposed on the upper and lower planes of a holder. For a computer peripheral device using the USB as the I/O interface standard, various kinds of storage devices have been well noted, such as the USB silicon disk. This kind of portable storage device has the advantages that the volume is smaller than that of the conventional portable storage devices, such as the floppy disk. Therefore, it is very convenient for carriage. However, the space for storage device is much greater than the amount for the conventional portable storage device. Furthermore, the capability of plug-and-play has been included between the USB and the computer, so that it has the advantages to avoid the extra connection device and reduce the tedious operation processes in use.
Referring to FIGS. 1-6, FIG. 1 and FIG. 2 are the drawing, schematically illustrating the conventional connection structure for the plug 10 and the receptacle 20 for the USB series A. FIG. 3 and FIG. 4 are the drawing, schematically illustrating the conventional connection structure for the plug 100 and the receptacle 110 for the USB series Mini-A. FIG. 5 and FIG. 6 are the drawing, schematically illustrating the conventional connection structure for the plug 30 and the receptacle 40 for the USB series Mini-B. In FIG. 1, the plug 10 includes a number of metal connection terminals 12, used to connect to the metal connection terminals 22 on the first holder 24, which is implemented in the receptacle 20, when the plug is connected to the receptacle 20 as shown in FIG. 1. A second holder 14 is used to hold the metal connection terminals 12. A metal frame 16 is used to fit into an outer frame 26 of the receptacle 20 when the plug 10 is connected to receptacle 20, in which the four elastic plates 28 arranged in up side and the down side on the outer frame 26 can elastically contact to the metal frame 16, so as to affix the plug 10. In FIG. 3, the plug 100 includes a number of metal connection terminals 102, used to connect to the metal connection terminals 112.on the first holder 114, which is implemented in the receptacle 110, when the plug 100 is connected to the receptacle 110 as shown in FIG. 4. A second holder 104 is used to hold the metal connection terminals 102. A metal frame 106 is used to fit into an outer frame 116 of the receptacle 110 when the plug 100 is connected to receptacle 110, in which the three elastic plates 118 on the outer frame 116 can elastically contact to the metal frame 106, so as to affix the plug 100. Likewise, the plug 30 in FIG. 5 includes a number of metal connection terminal 32, used to connect to a number of connection terminals 42 implemented on a first holder 44 in the receptacle 40, when the plug 30 is connected to the receptacle 40 as shown in FIG. 6. A second holder 34 is used to hold the metal connection terminals 32. A metal frame 36 is used to fit into an outer frame 46 of the receptacle 40 when the plug 30 is connected to receptacle 40, in which the three elastic plates 48 on the outer frame 46 can elastically contact to the metal frame 36, so as to affix the plug 30. However, in order to have the affixing function, the metal frame 16 is used to accept the first holder 24 when the plug 10 is connected to the receptacle 20, in which a second space 16 a exits between the metal frame 16 and the second holder 14. The second space 16 a determines the thickness of the metal frame 16 as well as the thickness of the plug 10. In order to have the affixing function, the metal frame 106 is used to accept the first holder 114 when the plug 100 is connected to the receptacle 110, in which a second space 106 a exits between the metal frame 106 and the second holder 104. The second space 106 a determines the thickness of the metal frame 106 as well as therefore the thickness of the plug 100. Likewise, in order to have the affixing function, the metal frame 36 is used to accept the first holder 44 when the plug 30 is connected to the receptacle 40, in which a second space 36 a exits between the metal frame 36 and the second holder 34. The second space 36 a determines the thickness of the metal frame 36 as well as therefore the thickness of the plug 30. Therefore, when a designer for the peripheral device of the computer system intends to reduce the peripheral device, which uses the USB as the I/O interface standard, the designer will be limited by the thickness of the plug 10, 100 and 30 and cannot design a peripheral device with a thinner appearance than the thickness of the plugs 10, 100, or 30.
For example, the USB silicon disk in the current market, the appearance is always designed to be a thin rectangular volume with a limitation of thickness by the thickness from the plug 10, 100 and 30 without being further reduced in thickness. Also and, the current memory card device usually has its standard size specification, such as, the IC card, which is usually used as the telephone card, the SIM card in cellular phone, as well as the IC credit cad, and the compact flash (CF) card and the secure digital (SD) card used in digital camera as the storage unit, the memory stick card, the multi medial card, the smart media card, the MG memory stick card, the XD picture card, the memory stick duo card, the Microdrive card, and so on. Due to the foregoing reasons, those cards should need an extra access apparatus with a cable connection and cannot be directly connected to the computer system via the USB series A receptacle for communication.
Also and, the CF card has the thickness of 0.33 cm but the USB plug, such as the series A, is thicker, such as 0.45 cm. If the thickness of the CF card is changed to 0.45 cm then it cannot be plugged into the CF slot of the digital camera. The computer uses the USB interface with the USB series A receptacle. In this situation, the CF card with the thickness of 0.33 cm cannot be installed with the convenient USB series A plug for directly connecting to the computer USB series A receptacle and providing a convenient way in data transmission. Thus, it needs a CF card reader to read data from CF card and through reader convenient USB series A plug for directly connecting to the computer USB series A receptacle. A USB “mini” type connector can be put in a CF card, but still needs a USB cable with “Mini” to “A” connector convert function, Otherwise it still can't directly connect a CF card into a computer common USB series A receptacle.
In the invention, a user can directly connect an additional connector of a CF card or a memory card to a USB series A receptacle. Further in the invention, the portable information storage device, which is connected to the peripheral device, can use the USB to connect to the computer, so that the use is more convenient.
The present invention provides a USB plug, which has different appearance from the conventional appearance but can be connected to a plug or a receptacle of the USB series A, series Mini-A, series Mini-B, series Mini-AB, so that the conventional issue about the over large thickness of the USB plug can be solved.

A second holder is used to hold the metal connection terminals of the plug. The USB plug has an outer frame and a first holder on which a plurality of metal connection terminals have been disposed.
The invention is a design which is different from the conventional design of the USB plug implemented with the metal frame by an over large thickness or a holder with over large thickness, so that the issue of over thickness of the USB plug can be solved.
The present invention uses an independent memory card associating with a master transfer card, which can be individually dismounted with the master transfer card. The master transfer card, for example, is a memory stick transfer card, with a controller to transfer the memory stick connector 7 pins signals to USB interface A. The independent memory card can be mounted or dismounted with the master transfer card, and connect to the USB interface A. A connection member can be optionally included when the independent memory card is combined with the master transfer card, wherein the connection member has a similar outer appearance to a different type memory card, so that the master transfer card combined with the independent memory card can be plugged into the slot of the memory card in different type. Also and, optionally master transfer card with one of the different memory card connector is able to connect the connector in the different memory card slot. Also and optionally, the independent memory card can be mounted or dismounted from an inner part of the master transfer card.
The present invention can also be applied to the design of the IEEE 1394 plug, which conventionally has a metal frame, causing an over large thickness. As a result, the thickness of the conventional IEEE 1394 can be reduced.
The objective of the invention includes providing an apparatus, which has an architecture of at least dual connector, allowing an inner-disposition single information storage card to be connected, wherein the single storage memory card has at least one or two different connectors. The dual connector can also connect with the single information storage card with one or two connector. As a result, the number of slots for adapting multiple memory cards can be reduced and the volume is therefore reduced. This is convenient for design in adapting the storage memory card with at least two different connectors or one connector. It is also convenient to be connected to the computer USB for data access.
One of the objectives in the invention is to provide a connection device with at least dual connectors, so as to connect to the connector of a single information storage card with at least two different connectors or one connector.
One of the objectives in the invention is to provide a connector of an inner device of a computer peripheral apparatus. The connector can be implemented on an insert portable memory device to transfer data with USB mass storage protocol. The portable memory device is inserted to a computer, and the computer uses the same USB mass storage protocol to transfer data to portable memory device, which can be dismounted and is connected to the USB connector of the computer in convenience. Also and, the portable memory device can be designed to be separated into two parts, so that when they are put together, it is suitable to insert into a slot. The separated part can include the memory card and a controller and has a connector to connect a device USB port. The function is like a USB silicon disk, but the size is small and long and thin for easy insert, so as to avoid the problem caused by too large area size. For example, for a CF card with a mini USB connector, the insertion of the CF card may touch the cables nearby, and against connector insertion to a USB port action, a CF card with rotate out connector, will support a long thin connector too.
The foregoing memory card can optionally have a connection member with the outer appearance similar to a different type of memory card, so that the memory card can be inserted into a slot of the different type memory card.

[0039]FIG. 18 is a drawing, schematically a plug with reduced thickness, according to the invention.
Referring to FIG. 7, FIG. 7 is a drawing, schematically illustrating a plug 50, according to an embodiment of the invention. In FIG. 7, the plug 50 includes a number of metal connection terminals 52 being exposed, used to electrically connect to a number of metal connection terminals 22 on a first holder 24 inside the receptacle 20 when the plug 50 is connected with the receptacle 20 in FIG. 2. A second holder 54 is used to hold the metal connection terminals 52 and at least one at bottom of the elastic plate 28 on the outer frame 26 of the receptacle 20 when the plug 50 is connected with the receptacle 20, or two elastic plates 54 at bottom are to elastically contact the second holder 54. So, it affixes the plug 50, in which at least one of the multiple elastic plates 28 on the outer frame 28 at the top will not contact with the plug 50. Wherein, each element in the plug 50 can have correspondingly similar specification and appearance, so as to assure that the USB plug 50 is compatible with the USB receptacle 20. However, the specification and the appearance can also be modified. For example, the metal connection terminals 52 can be the protruding points. It has been sufficient to only need a good contact between the metal connection terminals 52 of the plug 50 and the metal connection terminals 22 of the receptacle 20. It is also not always necessary for the second holder 54 to cover the bottom of the metal connection terminals 52. The second holder 54 can, for example, only hold the metal connection terminals 52 from the bottom for affixing. The plug 50 can also include an outer frame of a metal frame 56 or a non-metal frame, so as to connect to the outer frame 26 of the receptacle 20. One of the purposes of the second holder 54 or, the metal frame 56 is to connect in contact with the outer frame 26 of the receptacle 20, so as to provide the affixing function by contact. However, the second holder 54 can be properly adjusted on the thickness, so as to assure that the elastic plates 28 can have the affixing effect. Since the multiple metal connection terminal 22 on the first holder 24 are the design of elastic plates, it not only can assure the electric connection with the metal connection terminals 52 on the second holder 54, but also it has the affixing effect on the plug 50 by associating with the multiple elastic plates 28, The conventional USB plug 10 has the thickness of 0.45 cm, and the plug 50 has the minimum thickness, which allows to be plugged into the space between a bottom of the outer frame 26 of receptacle 20 and the first holder 24, wherein it has been sufficient to allow the multiple metal connection terminals 52 to have good contact with the multiple metal connection terminals 22 on the receptacle 20. The thickness can be less than 0.24 cm or even down to about 0.18 cm. Optionally, a protruding part for avoiding a reverse connection can be included, in which some portion would be thicker. However, the thickness of the plug 50 can be less than the USB series A plug 10 by 0.45 cm or down to less than 0.38 cm. In this manner, it can be implemented on a CF card with thickness of 0.33 cm, a memory stick card with thickness of 0.28 cm, a SD card with thickness of 0.21 cm, a XD card with thickness of 0.17 cm, a memory stick duo card with thickness of 0.16 cm, a Microdrive card, a PCMCIA card, or a thinner USB silicon disk, or a ATA Flash card, since the plug 50 can be used in light and small portable memory device, the plug 50 structure still support enough strength connect to a receptacle.

Wherein, each element of the plug 50 can have the similar specification and appearance with the corresponding elements of the USB plug 100, which is to be connected to the USB receptacle 110, so that the plug 50 is compatible with the USB receptacle 110. However, the specification and the appearance can be changed. For example, the metal connection terminals 52 can be the protruding points. It has been sufficient to only need the good contact between the metal connection terminals 52 of the plug 50 and the metal connection terminals 112 of the receptacle 110. It is also not always necessary for the second holder 54 to cover the bottom of the metal connection terminals 52. The second holder 54 can, for example, only hold the metal connection terminals 52 from the bottom for affixing. The second holder 54, in thickness, can be properly adjusted to assure that the elastic plates 118 can effectively perform the affixing function. Since the multiple metal connection terminal 112 on the first holder 114 are the design of elastic plates, it not only can assure the electric connection with the metal connection terminals 52 on the second holder 54, but also has the affixing effect on the plug 50 by associating with the multiple elastic plates 28.
Likewise, when the plug 50 is connected to the receptacle 40 in FIG. 6, the metal connection terminals 52 being exposed, are used to electrically connect the multiple metal connection terminals 42 on the first holder 44 inside the receptacle 40. The second holder 54 is used to hold the metal connection terminals 52 and affix the plug 50, wherein at least one of the multiple elastic plates 48 on the outer frame 46 of the receptacle 40 can elastically contact the second holder 54 to affix the plug 50 when the plug 50 is connected to the receptacle 40. Wherein, each element of the plug 50 can have the similar specification and appearance with the corresponding elements of the USB plug 30, which is to be connected to the USB receptacle 40, so that the plug 50 is compatible with the USB receptacle 40. However, the specification and the appearance can be changed. For example, the metal connection terminals 52 can be the protruding points. It has been sufficient to only need the good contact between the metal connection terminals 52 of the plug 50 and the metal connection terminals 42 of the receptacle 40. It is also not always necessary for the second holder 54 to cover the bottom of the metal connection terminals 52. The second holder 54 can, for example, only hold the metal connection terminals 52 from the bottom for affixing. The second holder 54, in thickness, can be properly adjusted to assure that the elastic plates 48 can effectively perform the affixing function. Since the multiple metal connection terminals 42 on the first holder 44 are the design of elastic plates, it not only can assure the electric connection with the metal connection terminals 52 on the second holder 54, but also has the affixing effect on the plug 50 by associating with the multiple elastic plates 48. The USB series mini-A plug 30 or the mini-B plug 100 have the thickness of 0.3 cm. The minimum thickness of the plug 50, which allows to be plugged into the space between a bottom of the outer frame 46 of receptacle 40 and the first holder 44. Wherein, it has been sufficient to allow the multiple metal connection terminals 52 to have good contact with the multiple metal connection terminals 42 on the receptacle 40. The thickness of the plug 50 can be less than 0.15 cm or even down to about 0.08 cm. Optionally, a protruding part for avoiding a reverse connection can be included, in which some portion would be thicker. However, the thickness of the plug 50 can be less than the 0.3 cm.

Referring to FIG. 12, FIG. 12 is a drawing, schematically illustrating the plug 50 according to the fifth embodiment of the invention, wherein the actual situation is shown when the plug 50 of the invention is connected to the USB receptacle 20, 40, 110 in FIGS. 1, 4, and 6. For convenient descriptions in FIG. 1, the receptacle 20 is used as the example. In order to further reduce the thickness of the plug 50 with respect to various needs, the thickness of the plug 50 can be reduced down to a degree, at which the plug 50 second holder 54 will not contact with the elastic plates 28, 48, 118 when the plug 50 is connected to the receptacle 20, 40 and 110, and the second holder 54 in the plug 50 can be implemented with a number of elastic plates 98 at the bottom side to have contact with the metal frame of the receptacle 20, 40, 110. Or, second holder 54 has a metal frame rack in bottom or both side touch the bottom outer frame of receptacle 20, 110, or 40, is used to strengthen the connection effect. The metal connection terminals 52 of the plug 50 can be a design of elastic plate.
In the invention, the plug 50 and the embodiments 1-5 have disclosed several options. The plug 50 of the invention can effectively reduce the thickness of the conventional USB plug, so as to be suitable for use in various computer peripheral devices. The present invention can be also applied to a mini type IEEE 1394 connector with four metal connection terminals, which is similar to the mini USB connector. The different is the size and the outer appearance. However, the connection mechanism between the plug and the receptacle are similar to the mechanism in the USB case. The present invention can also be applied to the mini type IEEE 1394 connectors. Referring to FIGS. 13-16, FIG. 13 is the example for actual application using the plug 50 as shown by a plug 120, which is implemented on a USB silicon disk drive 70 without using the manner of cable connection. Wherein, the plug 120 can be the plug 50 shown in FIG. 7. The silicon disk drive 70 has a indent space 80. The plug 120 can be implemented on the indent space 80 by a non-retractable manner. The plug 120 can also be implemented on the silicon disk drive 70 by a protruding and non-retractable manner. The protruding plug 120 can be directly connected to a USB receptacle, and the receptacle 20, 110, 04 40 of a cable can also be directly connected to the plug 120 on the indent space 80. The plug 120 can also be implemented in the indent space 80 by the retractable manner. When the plug 120 is to be connected to the receptacle 20, 110 or 40, the plug 120 can then be shifted out from the indent space 80. When the plug 120 is not to be connected to the receptacle 20,110, or 40,the plug 120 can be retracted into the indent space 80.
[0050]FIG. 14 is the example for the second actual application using the plug 50 as shown by a plug 120. An IC card 72 has the metal connection terminals 92 used by a reading apparatus to read data, but also has a plug 130, which can be the plug 50 shown in FIG. 7 and is implemented on the IC card 72 without cable connection. The IC card 72 has an indent space 82. The plug 130 can be implemented on the indent space 82 or protruding from the IC card 72 by a non-retractable manner. The receptacle 20,110, 04 40 of a cable can also be directly connected to the plug 130 in the indent space 82. The plug 130 can also be implemented in the indent space 82 by a retractable manner. When the plug 130 is to be connected to the receptacle 20, 110 or 40, the plug 130 can then be shifted out from the indent space 82. Alternatively, the plug 130 can also be disposed in the indent spacer 82 and when it is to be used, the plug 130 is shifted out by rotating an angle of 90 or 125 degree or others. The metal connection terminals of the plug 130 being shifted out are connected to the chip of the IC card 72 via a conductive line, so that the plug 130 can be directly connected to the receptacle 20, 110, or 40 of the computer. When the plug 130 is not to be connected to the receptacle 20, 110, or 40, the plug 130 can be retracted into the indent space 82.
[0051]FIG. 15 is the example for the third actual application using the plug 50 as shown by a plug 140. A CF card 74 has a slot 94 for use by digital camera to access the data. Also and, a plug 140 is implemented on a CF card 74, wherein the plug 140 can be the plug 50 in FIG. 7. The CF card 74 has an indent space 84. The plug 140 can be implemented in the indent space 84 by a non-retractable manner, wherein the plug 140 can also be exposed or two sides of the plug 140 have open gaps. The receptacle 20,110, or 40 of a cable can also be directly connected to the plug 140 in the indent space 84. The plug 140 can be implemented in the indent space 84 by a retractable manner. When the plug 140 is to be connected to the receptacle 20, 110 or 40, the plug 140 can then be shifted out from the indent space 84. Alternatively, the plug 140 can be disposed in the indent spacer 84 and when it is to be used, the plug 140 is shifted out from the CF card by rotating an angle. The plug 130 can thereby be directly connected to the receptacle 20, 110, or 40 of the computer. When the plug 140 is not to be connected to the receptacle 20, 110, or 40, the plug 140 can be retracted into the indent space 84. The appearance of the CF card 74 is then returned and can be inserted into the slot of the digital camera, a memory card with a long-thin shift out plug 40, will be easier to inset into receptacle, because a CF size will touch other nearby cable and against the inset action, this is the reason why USB silicon disk was long-thin shape.
One design is as follows. Plug 140 also can be shifted out from the CF card (master card) or other memory card, together with at least one memory card and at least one controller chip. As a result, it becomes an independent memory card, the controller chip for controlling the data storage and transmission can be integrate into the memory card. The controller has the function to control the system and data transfer. As a result, after the plug with the memory card is shifted out, the shifted-out independent memory card can be completely separated from the master card, or alternatively still has some mechanical connection without complete separation. Thus, it is convenient for the action of retracting back into the master card. The master card can optionally include one controller chip for controlling the information transmission. The independent memory can be inserted into a computer USB port, and become an independent memory card, like a USB memory card. Therefore, it is smaller than a CF card and can be designed with long thin shape to easy insertion to the USB PORT slot. The independent memory card can be retracted back to the master card.
When the plug 140 of the independent memory card is retracted, it can be connected to a USB interface connector A in the master card (memory transfer card), for example, a memory stick transfer card (master card) with a USB interface connector A and with another memory stick card standard 7 pins connector E, so that the 7 pins of the connector E on the memory stick transfer card can be connected to the inserted electronic device, such as the digital camera, for transmitting data. The control device function transfers different type of memory card connector signals for example: memory stick card 7 pins connector E signals, to the USB interface signals or others to the connector A, with a function as a USB Host Mode. One option is to limit the USB communication protocol only connect to a memory card, to simplify the design, then the independent memory card having a USB interface connector B can connect to connector A. The independent memory card can be designed with only one USB interface and connect to two connectors, and only allow one connector data communication at same time to save one USB interface, or design with two USB interfaces and connect to two connectors, or design with only one USB interface and connect to only one connector A. It can be designed that when independent card is connected to master card, the other connector in independent memory card can still insert to a computer USB port for data communication, since at this time when the master card didn't insert to a device, and no power supply from master card, and control device can set to disable. Use only one USB interface a design is: a manual switch and optionally select connect independent memory card USB interface connector B to connector A or connect to external connector. Or USB interface connector B cam be manually moved (example: a rotation plug) to connect connector A or connect an external device USB port, then only one USB interface still works. Also and, the independent memory card can be directly connected to electronic device via the at least one of the 7 pins on the memory stick transfer card, the independent memory card can optionally inside the memory stick transfer card(master card), or it was connected with the memory stick transfer card, and connect together can be with the outer shape, the outside shape can inserted to a standard memory stick card slot, and function like a standard memory stick card. And can be optionally design with one other connector at independent memory card another side, and able connect to a computer USB port, or another way is the independent can take out and able connect to a device USB port, the design needs no card reader, in the upper different case, USB interface connector can be a non-standard USB connector, being thinner, so for being able to be installed in a memory stick card or other memory card, the upper different design can be done in different types of memory card.
There are many options about how the data is transferred between the memories to the inserted digital camera device, and many different connector design option. One design is that the plug 140 of the independent memory card combined with a master card, can also be directly connected to a USB connector inside a digital camera for information communication, so that the function of the master card can be only to mechanically support independent memory card and the mechanical member for insertion into the memory stick slot. One option is that the independent memory card have at least two connectors, a plug 140 connector, and another connector A, which can be directly connected with a connector, which is installed inside of the digital camera. In this manner, a memory transfer card (master card) may be not necessary to include a connector C with 7 pins required by the conventional memory stick card or a controller. It can be seen that the only need for the master card is the connection function to insert into the affixed slot. The memory card, such as a memory transfer card combined with the independent memory card or memory transfer card with independent memory card inside, can optionally include a connection member with the outer appearance similar to-a different type of memory card, so that the memory card can be inserted into one slot of the different type memory card.
Alternatively, the independent memory card can include at least a dual connector, of which one is the plug 140 and another one is a connector A, in which the independent memory card can be connected to a connector B on the CF card via the plug 140 or the connector A. The connector B of the CF card can be used for USB signal transmission or other uses. The CF card can include a connector C with the conventional 50 pins and a controller, so that it provides for the external electronic device to connect on the connector C via the 50 pins. In this manner, the signals for CF card can be converted into the signals of a USB interface and transmitted to the connector B, so as to connect to the independent memory card. Alternatively, the CF card can only be simply the connector C with conventional 50 pins for connecting the external electronic device at the connector B, so that the information data can be transmitted to the memory card on the CF card (master card). Furthermore, the CF card can also be treated as only a mechanical support member without limitation by the function of actual connection.
The another design is a memory card architecture, which can include a master card. The master card has an I/O port, capable of connecting with a first external electronic device. A controlling unit is implemented on the mater card, used to the I/O interface port into a USB interface. A memory card having a USB interface I/O port member is capable of connection with a second external electronic device. Wherein the memory card can be mounted/dismounted on the master card or integrated with the master card as a choice from a user, and by a mechanical operation, the USB interface I/O port member can be coupled with the I/O port of the master card. Wherein, only one at a time for information communication can be selected from the group consisting of case 1 that the USB interface I/O port member of the memory card is coupled with the I/O port of the master card and case 2 that USB interface I/O port member of the memory card is coupled with the second external electronic device.
In the forgoing architecture, the controlling unit can convert the different signal protocol of memory card to the USB signal transmission protocol. The USB interface I/O port member can be, for example, like the structure as shown in FIG. 18 with the rotation part, in which when the connector is put back by, i.e., hand, then it is connected to the USB interface of the master card.
The foregoing design of master card with the independent memory card can also be applied to the other kinds of memory card. The independent card with respect to the master card can optionally include a connection member with the outer appearance similar to a different type of memory card, so that the memory card can be inserted into a slot of the different type memory card. The independent memory card can be retracted into the CF card, and then the CF card can be inserted into the CF slot in, for example, a digital camera. The CF card has the multiple function to provide for, i.e., a USB silicon disk (independent memory card) being coupled together. The independent memory card can be a long thing structure, so that the independent memory card can be plugged into the plug 140 of the computer, without being restricted by the size of the CF card.
[0059]FIG. 16 is the example for the fourth actual application using the plug 50 as shown by a plug 150. A SD card 76 has a slot 96 for use by digital camera to access the data. Also and, a plug 150 is implemented on the SD card 76, wherein the plug 150 is implemented on the SD card without cable, wherein the plug 150 can be the plug 50 in FIG. 7. The SD card 76 has an indent space 86. The plug 150 can be implemented in the indent space 86 by a non-retractable manner, wherein the plug 150 can also be exposed. The receptacle 20, 110, 04 40 of a cable can also be directly connected to the plug 150 in the indent space 86. The plug 150 can also be implemented in the indent space 86. When the plug 150 is to be used, the plug 150 can be shifted out by rotating an angle. The plug 150 can also be implemented in the indent space 86 by the retractable manner. When the plug 150 is to be connected to the receptacle 20, 110, or 40, the plug 150 would be shifted out from the indent space 86. When the plug 150 is not to be connected to the receptacle 20, 110, or 40, the plug 150 can be retracted into the indent space 86. The plug 150 can also be implemented by protruding out from the SD card 76 without retraction. The protruding plug 150 can be directly connected to the USB receptacle of the computer. The SD card can also be disposed into the slot in a digital camera. The plug 120,130, 140, 150 as shown in FIGS. 13-16 can also be uses in the USB series A plug 10 in FIG. 1, the USB series Mini-A plug 100 in FIG. 3, or the USB series Mini-B plug 30 in FIG. 5.
In the fifth application of the plug 50 in the invention, the metal connection terminals 52 can be changed into, i.e., elastic plates, so as to allow a connector to be inserted into. The connector can be the USB plug 30, 10,100 in the computer. Likewise, the plug can also be connected to the USB receptacle, or even a reversed arrangement of the plug 50 suitable for use in the actual design.
In application 6, it is related to a design of the connectors for the peripheral equipment of the computer and an information storage device. The computer system is, for example, a notebook computer, and the information storage device, for example, is a PDA or storage device. For the storage device of the digital camera, it is, for example, a CF card. After the CF card is released out from the peripheral device of computer, conventionally it needs a reading apparatus to read the information. The information in the CF card can be input to the USB port of the computer via the reading device with the USB connector. The portable information storage device inside the peripheral device of computer can be a silicon disk or memory device, implemented with the conventional plug of USB series A 10, USB series Mini-A 100, or series Mini-B 30. The silicon disk or memory device can also be implemented with a plug of the invention, which can be connected to the receptacle or the plug of USB series A, USB series Mini-A, series Mini-B, series Mini-AB. The silicon disk or memory device can be disposed inside the peripheral device of computer. The peripheral device of computer is implemented with a connector, which can be connected with the plug. This connector can be the receptacle in USB series A 10, USB series Mini-A 100, or series Mini-B 30, or can be the plug 50. In this design, The computer system can download data to the portable information storage with USB mass storage class protocol, the portable information storage device of the peripheral device can be released out and be directly connected or connected via a cable, as shown in FIG. 17. The cable can be, for example, the cable used for converting the receptacle into the plug, in which the data signals are not changed and can be directly connected to the USB port of the computer, and can be read data with USB mass storage class protocol. In this manner, it is convenient for reading the information of the portable information storage device. In FIG. 17, an information storage card 1000 is implemented with the plug 1006 of the invention compatible with the USB specification. The plug 1006 is disposed on the rotation arm 1004. The rotation arm 1004 is mounted on the information storage card 1000 via a rotation member 1002, in which the interconnection line (not shown) is used to extend the connection terminals to the plug 1006. Moreover, as shown in FIG. 16 or FIG. 17, the plug 1006 can also be designed to be directly connected to a connector, even the plug remains in the retraction position, the rotated-out plug can be implemented in memory card or a hard disk, or a PCMCIA card.
In general, the peripheral device of computer can be implemented with a receptacle to be connected to a plug. The plug is implemented on a portable information storage device inside the peripheral device and is to be connected to the receptacle. The portable information storage device can be released out and is directly connected, via the plug, to a USB receptacle in an apparatus, or the portable information storage device can be released out and is connected by cable, via the plug, to a USB receptacle in an apparatus.
For the seventh application, the storage device in the market used by the digital camera has the design of dual slot and dual card, such as the CF slot and SD slot. The peripheral device of computer in implemented with two connectors as a dual connector for adapting the two cards. The user can select one of the two cards to plug into the digital camera. However, since it needs to be implemented with the dual slot, it then needs a larger volume. The invention proposes that a memory card has been installed inside a computer peripheral device, such as a CF card slot with at least two connectors. The CF card can have the original connector with 50 pins, but also have another connector, so as to form a dual-connector card. For example, the another connector can be the exposed plug 50 of the invention, which can be connected to the receptacle of, for example, USB series A, series Mini-A, or Mini-B. Alternatively, the another connector on the card can be the usual USB plug of USB series A, series Mini-A, or Mini-B. The peripheral device is implemented with two connectors inside. The two connectors can be the two connectors of the portable information storage device, which has been inserted. For example, The information storage device has the receptacle for CF card, SD card, or multimedia card as well as another connector. This another connector can be the exposed plug 50 of the invention, which can be connected to the plug or receptacle of, for example, USB series A, series Mini-A, or Mini-B. The peripheral device can detect and select one of the two connectors to read the information on the information storage device. In this design, the user has multiple choices to select the portable information storage device. One choice is the CF card, which can be read by the card reading apparatus. One choice is the card with dual connector, in which one connector can be the USB plug of series A, series Mini-A, or series Mini-B, as well as the other connector is the connector of the CF card to connect to the silicon disk or memory device. The memory device has a CF card slot with about conformal shape with the appearance of the CF card, so that it can be released and connected to a computer for reading the information via the USB port. The digital camera can also select a fast transfer rate USB 2.0 to send data to this memory card. One choice is also the card with dual connector, in which one connector can be plug 50 of the invention capable of connecting to the USB plug, or the plug 60 (see FIG. 18, the 10 applications latter). Then, another connector is a CF connector for the silicon disk or memory card. The connection can be the CF slot about conformal to the CF card, is the connector of the CF card to connect to the silicon disk or memory device. One choice is the silicon disk or memory device, which has the CF slot about conformal to the CF card, implemented with a plug 50 or plug 60 of the invention, for connecting to USB series A, series Mini-A, or series Mini-B. Another option is that a design of the CF card like the embodiment three has a master card with the independent memory card. The peripheral device of the computer is implemented with at least two connectors, so that one of the connector of the master card and the connector of the independent memory card, or a single connector to connect to the master card or the independent memory card.
The connecting part inside the peripheral device at least includes two connectors. The peripheral device of computer can have a single slot, allowing different card to be plugged in, wherein the slot can be connected to the at least two connectors or single connector on the card, which has been plugged into the single slot. In this manner, for example, it only needs a CF-card slot, which is rather small in size, and can allow the different information storage cards to be plugged in for use. Optionally, a faster transfer data connection can used, when the card has this kind of connector, and still keep the function to connect a standard one connector CF card, which was being used a lot. This method is also suitable for use in the memory card with different specification.
The electronic device (USB host) can use inner connector satisfying the protocol of the USB mass storage, so that it can use the memory card (USB device) for data storage and transmission. The memory card can be dismounted. The electronic device can use the same protocol of USB mass storage to communicate with the memory card for information transmission.
With respect to the information storage card installed in the digital apparatus, the single storage card can have two different connectors, of which one can be the plug of the invention in reduced thickness for the USB connecting manner. As a result, the information storage card can used the USB interface manner to be directly connected to the external apparatus, such as the computer system.
With respect to a memory card installed in an electronic device, a standard USB connector may be not suitable for being installed on a slim memory card due to over thickness. However, the USB interface is a standard commonly used, so as to provide a standard protocol for data communication and to be easy for data communication with the computer. A design of the invention is that a single memory card can be installed with at least one USB interface. The at least one USB interface has multiple signal terminals including the power, Gnd, D+, and D−. The multiple signal terminals of the interface can be exposed, so as to be used for a slim memory card. When the memory card is plugged into a memory-card slot of the electronic device, it can provide multiple naked-like terminals (for example, multiple terminals of a SD card, contacting the terminals on the connector of the SD card. The terminals of the memory card can be the 9 pins of the original SD or connection terminals on the SD card). The connection function is achieved by contact the terminals. As a result, the data communication with the USB interface still can be commonly used by the users. After the memory card is released out, the connector of the interface can be designed to include the USB plug of the invention with exposed terminals and reduced thickness. Thus, the memory card can use the USB manner to connected to the external system, such as the computer system. The computer can easily access the data in the memory card by the USB interface. The memory card can optionally has a connection member for the different memory type, so that it can be inserted into a slot of the different memory type. The terminals of the USB interface can be a designed by the exposed manner, suitable for installation on a mobile electronic device. For example, it can be installed in a network communication card and is plugged into the PDA.
The electronic device can be designed to connect with different type memory card at the same I/O port A, with such as a SD card port C or a USB interface card port D. Thus, it can have different protocol in data communication and different signal form. For example, the electronic device has the standard 9-pin connector for the SD card but the connected part into the slot can be the terminals to connecting the 9-pin or a card with the appearance similar to the SD card, which has the USB connection terminals or other type of interfacing terminals. The electronic apparatus or device has the detection function to detect the specification of the connected one, so that a proper communication protocol can be set up for communication. The detection function can be a detection of the communication protocol, or can be a switching detection. When the card with the appearance of the SD card is plugged in, the switching device is triggered. However, the standard SD card will not trigger the switching device. The detection function can also be a signal from a terminal of the SD appearance-like card. When the SD appearance-like card is plugged, the electronic device will detect the signal on the specific terminal. For example, when the SD appearance-like card is plugged, two of the 9-pin of the electronic device are conducted. However, when the standard SD card is plugged, the switching device will not be triggered. Alternatively, the voltage level or the impedance on the connected terminal can be detected for discerning. Or, even a specific signal on the specific terminal can be detected. In this manner, it is possible to detect a SD card appearance but with the USB interface. One specific terminal of the memory card can be optionally set to contact with a terminal of the I/O port D. The SD appearance-like card can have multiple terminals of USB interface and the structure of the connector can be connected to a USB connector of the external electronic device, such as a computer. Thus, the card can be only needing one USB interface. The two USB interface is not necessary because the two connectors can share the same USB interface.
Therefore, a connection structure between a electronic device and a USB interface in the invention can be as follows. Inside the electronic device, it includes a connector, a slot with a connector of USB interface, and a structure member for adapting the installation and connection of the USB interface to the memory card. Wherein, the USB-interface memory card can be plugged into an inner part of the electronic device for connecting with the connector of USB interface in the slot and for data communication. Optionally, a little area of the memory card can still stay outside of the electronic device, so as to pull out a inserted card. The electronic device can be a USE host side optionally as a connector of USE interface, for connecting with memory card by a USE interface. It can reduce the complexity of USE protocol design.
Another design of the invention of the memory card includes a memory body used to store information. A control device, having at least two USE interface, is used to control the data communication. The control device can optionally be integrated with the memory body. A dual connector has a connection side for connecting at least two USE interfaces, in which the memory card uses a connector of USE interface to connect the electronic device for data communication. The another connector of the memory card of USE interface can connect to the memory card mounted on the electronic device for data communication.
Alternatively, the memory card includes a memory body for storing information. A control device, having one USE interface, is used to control the data communication.
The control device can optionally integrated with the memory body. A dual connector has a connection side for connecting to only one USE interface, in which the memory card uses the connector of USE interface to connect the electronic device, such as a computer, for data communication. The another connector is to connect a memory card on a electronic device, such as a digital camera, for data communication, these two connectors will not use in the same time for data communication.
The outer appearance of the different memory card is compatible for plugging into a slot for one selected from the group consisting of an IC card, a CF card, a SD card, a XD picture card, a memory stick duo card, a memory stick card, a multimedia card, a MG memory stick card, a smart media card, a Microdrive card, a PCMCIA card, and a USB silicon disk.
For the eighth application, one connector is to be connected to one connector on the CF card as shown in seventh application. The connector can be the plug 50 of the invention, which can be connected to the USB plug or the USB receptacle of series A, series Mini-A, series Mini-B. The connector can be the plug 50 with the metal connection terminals 52 as the elastic plate. The plug 50 in implemented with a second holder 54, so as to hold the metal connection terminals 52, which can be a design of elastic plates. In this manner, the plug 50 can be connected to another reversed plug 50 from up side or down side. The second holder 54 in the plug 50 can be implemented with at least a protruding part 58 at the edge, so as to prevent a reversed connection from occurring.
In the ninth application, one connection apparatus, used in the computer system as described in seventh application, has the design of at least two connector, so as to connect to at least two different connectors on a single information storage card. One of the two connector can be the connector as described in eighth application and the other one is used to be connected to a memory card, such as IC card, CF card, SD card, multimedia card, XD picture card, memory stick duo card, secure multimedia card, memory stick, MG memory stick, a Microdrive card, a PCMCIA card, or smart media card. The single data storage card can include a master card with an independent card, as described in embodiment 3.
In the tenth application, referring to FIG. 1 again, a conventional USB series A plug 10 has the thickness of 0.45 cm, which can be plugged into the USB series A receptacle 20 in FIG. 2. The plug 10 has multiple metal connection terminals 12, used to be connected to have the electrical connection with the multiple metal connection terminal 22 on the first holder 24 of the receptacle 20 when the plug 50 is connected to the receptacle 20. The metal frame 16 of the outer frame is used to contact in connection with the outer frame 26 of the receptacle 20.
Referring to FIG. 18, it is a drawing, schematically illustrating another plug with reduced thickness according to the invention. The invention is implementing another plug 60 on a memory card, such as a CF card. The plug 60 has a reduced thickness by less than about 0.38 cm or even down to 0.28 cm, which is less than the thickness of the conventional USB series A plug. It can satisfy the requirement from the CF card by 0.33 cm or approach to the thickness of the memory stick card by 0.28 cm, so as to achieve the thickness used in PCMCIA card. As a result, the plug 60 can be implemented on the CF card or the memory stick card. It only needs to allow to be plugged into slots of the CF or memory stick card. The plug 60 can be plugged into the USB series A receptacle 20 in FIG. 2. The plug 60 can be directly affixed onto a CF card. A receptacle on the USB cable for series A can be connected to the plug 60. The plug 60 has a second holder 64, used to hold the metal connection terminals 62. Also and, when the plug 60 is connected to the receptacle 20. At least one of the elastic plates 28 on the outer frame 26 of the receptacle 20 at the up side and each the edge side can elastically contact the outer frame 66, such as a metal frame, of the plug 60. Thickness of the second holder 64 is less than the thickness of the second holder 64 of the conventional USB series A plug 10, so as to reduce the total thickness of the plug 60. The second holder 64 can also be used just for holding the metal connection terminals 62 without need to cover the whole metal connection terminals 62 from the bottom. It can have an outer frame 66, like the metal frame 16 but thinner, to enclose the second holder 64. The bottom of the second holder 64 optionally has the outer frame 66. When the plug 60 is plugged into the receptacle 20, the outer frame 66 is inserted into the space between the first holder 24 of the receptacle 20 and the metal frame 16. The outer frame 66 contacts the metal frame 26 of the receptacle 20. At least one of the elastic plates 28 on the metal frame 26 at the up and each edge sides is elastically contacting with the outer frame 66, so as to provide the affixing effect. As a result, the second holder 64 and the metal connection terminals 62 being held can tightly contact on the first holder 24 on the receptacle 20 and the metal connection terminals 22. The elastic plates 28 on the metal frame 26 at the middle bottom may not contact the plug 60 due the reduction of thickness. One of the purposes of the second holder 64 or the metal frame 66 is to connect in contact the outer frame 26 of the receptacle 20, so as to provide an affixing function.
The metal connection terminals 62 on the second holder 64 can also be a design of elastic plates, wherein each element of the plug 60 is compatible, in specification and appearance, with the USB series A plug 10, which is used to be plugged into the receptacle 20. However, the specification and the appearance can also be modified. For example, the metal connection terminals 62 can be the exposed protruding terminals. It only needs to have a good contact between the metal connection terminals 62 of the plug 60 and the metal connection terminals 22 of the receptacle 20. It is also not the absolutely necessary for the second holder 64 to cover the whole metal connection terminals 62 from the bottom. The second holder 64 can only be used to hold the metal connection terminals 62 from a bottom. The preferred embodiment is to assure for holding and protecting the metal connection terminals 62. The thickness of the plug 60 can be (1) the thickness of the outer frame 66, (2) the thickness between the outer frame 66 and the second holder 64 (that thickness is thickness of the first holder 24 of the receptacle 20), and (3) the total thickness of the second holder 64 of the plug 60 and the metal connection terminals 62. The total thickness is less than 0.38 cm or can even down to about 0.28 cm. The plug 60 can be affixed onto the CF card. The plug 60 at each edge side has a space, where a USB cable with series A receptacle can be connected with the plug 60. The plug 60 can also be designed by a rotation arm or a retractable design, so that the plug can be directly plug into the receptacle, the outer frame 66 can be only keep the top side, and remove bottom, or other side.. The log thin connector can prevent from the difficulty of insertion action due to the over large volume of the CF card. The outer frame 66 can optionally keep only the upper part in which the side and the bottom part are removed. The plug 60 can include a member for avoiding short circuit when a reverse connection is accidentally taken. For example, a top of the outer frame 66 of the plug 60 can have an indent space 80, The position of the indent space 80 can be matched to the expected position of the power terminal when the connection is reverse connection. In this manner, even a reverse connection is made, the power short circuit will not occur. Alternatively, when the thickness for the second holder 64 of the plug 60 and the metal connection terminals is greater than 0.12 cm, then the reverse connection will not easily occur. A protruding structure at the end part can be designed, For example, a protruding part is included in the memory stick card at the end part, then the thickness of the memory stick is thicker than the specification of 0.28 cm, such as 0.3 cm. Since the end part with the protruding structure, the end part of the card will incapable of plugging into the slot of the memory stick card. However, the card can be plugged into the slot of memory stick card.
In conclusion, comparing with the conventional USB connector, the plug of the invention can effectively reduce the thickness of the plug, which can be connected to the USB plug or USB receptacle. Then, the invention allows the peripheral device of computer to be designed with better appearance and having more options, and the design principle for the master card and independent card can be used in other different type of memory cards.
