For example, hard disk drives and optical disk drives in early computers were installed with electric age machines (4). However, due to the market demand for future development, there is a so-called removable portable device, the basic concept of which uses a frame to provide space for positioning electronic devices (such as hard disks), and has electricity Teng electrical connection interface. Such structures are, for example, the Republic of China Patent Bulletin No. 193440 "New Structure of Removable Hard Disk Rack" and the Republic of China Patent Notice No. 251710 "Removable Hard Disk Conversion Rack", Republic of China Patent Notice No. 264165" "Rack of removable storage system", etc. _]Because of these well-known portable 4 hard disk improvements, the products on the market have already supported hot-swappable and sophisticated interfaces (such as UBS, IEEE 1394, eSATA), and with these pass-through interfaces Increasing the transmission rate makes portable devices a popular information product. The current product structure is as described in the Republic of China Patent Publication No. 549525, "hard disk fixing structure of a hard disk external box", which discloses that a hard disk external box includes a front cover, a case and a back cover, the case The utility model has a space for accommodating a riser card and a hard disk, wherein the riser card has a connection interface to the outside and a socket slot electrically connected to the hard disk. The foregoing structure is a typical external hard disk. 099135870 Form No. A0101 Page 3 of 18 0992062694-0 201218194 [0004] [0005] In order to support (4) plug-and-play function, the riser card provides handshaking and interface conversion between hardware. Features. Therefore, the riser card is necessary, and the control chip on the riser card also needs to be powered to perform its function, so to drive the portable device to operate at least - low voltage power (usually ... DC power) is required to start the Riser card. However, since the performance and high-revolutionary devices must have sufficient electric power to drive the low-voltage power supplied by Lin itself (some high-speed transmission interfaces or even no power supply) is not enough to drive portable devices, nowadays Most portable devices require two power cables in addition to one transmission cable. The above case is not a specific structure, and the circuit architecture is shown in Figure 1 and Figure 2. An external hard disk is taken as an example. The switch card 8 has a power input terminal 80 and a signal wheel input terminal 81. The power cable 6 has a power connector 61 electrically connected to the power input terminal 80. The power cable 6 is connected at the other end to the power source 60 to turn on 12v power to the riser card 8... The transmission line 7 has a signal connector 71 electrically connected to the signal input terminal 81, and the transmission cable 7 The other end is connected to a signal source to input the signal to the riser card 8. The riser card 8 further has a power output 84 and a signal output 85 that transmits 12V power to the power output 84. The power output terminal 84 and the signal output terminal 85 are electrically connected to a power receiving end 90 and a signal receiving end 91 of a hard disk 9 respectively, and transmit signals and power to the hard disk 9. The adapter card 8 includes an interface control chip 82 and a power converter 83. The signal input terminal 81 is electrically connected to the interface control chip 82. The USB interface is taken as an example, and the signal input terminal 81 extends. A signal path 81〇 and a trigger signal path 81丨 are connected to 099135870. Form number A0101 Page 4/18 pages 0992062694-0 201218194 Ο [0006] °Hai " face control chip 82, at the signal input terminal 8 through the transmission When the cable 7 is electrically connected to the source 70, the "face control wafer 82 is triggered through the signal path 8 to cause the interface control chip 82 to learn that the signal source 7 is connected to the riser card 8. It is important to note that although the USB interface itself has a power pin that can supply 5V of power, the interface control chip 82 does not use the power provided by the USB interface. The interface control chip 82 still needs to be biased to power up. Thus, the power absorber 83 draws 12V power from the power input terminal 8 and the power output terminal 84 and converts it into ... power output. The 5V power outputted by the power converter 93 can be used not only as the bias power for starting the interface control chip 82, but also to the power output terminal 84_ and supply the hard disk 9 for operation. Continuation of the disclosure of FIG. FIG. 2 is a block diagram of a circuit structure of the card 8 in a more detailed manner. The adapter card 8 further includes a timing generating capture and (four) memory 88 electrically connected to the interface control chip 82, and the timing generator 87, the memory 88 and the interface control chip. The operation between 82 is a well-known technique in the technical field, and therefore will not be described again. The power converter 83 draws 12V power from the power wheel, the brother 8〇 and the power output terminal 84, and converts to form 5V power, and is modulated by the wafer power supply unit 86 or the electric power. The interface controls the bias power of the wafer 82. [0007] Due to the above-mentioned prior art, the power supplied by the USB interface is not utilized well, so that the adapter board 8 needs to be provided with the power converter 83 and the wafer power supply unit 86, occupying a large amount of the surface of the adapter board 8. Space and cost make it difficult for manufacturers to reduce size. SUMMARY OF THE INVENTION 099135870 Form No. A0101 Page 5 of 18 0992062694-0 201218194 [0008] In the conventional hard-outer box, the adapter board as the connection interface needs to have its own power converter to maintain the adapter board.
