Problems solved by technology

[0003] If the above-mentioned peripheral devices are connected to the computer in different ways, since the motherboard cannot provide so many connection interfaces, repeated plugging and unplugging often confuses users.
However, ordinary notebook computers can be connected to various peripheral devices through connectors, but the pin position signals of the connectors are tailor-made according to the configuration of each connection interface of the notebook computer, and cannot be used in one package. criticized by

Embodiment Construction

[0015] As shown in FIGS. 1 to 3 , basically, the present invention is composed of a casing 1 and a circuit board 2 .

[0016] Wherein, the casing 1 has a device space 11 for accommodating and locating peripheral devices such as the CD player A, the card reader B, the floppy disk drive C and the hard disk drive D, and the outer surface of the casing 1 is provided with several holes, The groove is used for the exposure of the USB interface 21, the power input terminal 22 or at least one USB interface socket 25 described later, so as to facilitate the connection. This is a known technology and will not be described in detail here.

[0017] The circuit board 2 is provided with a USB interface 21 and a power input terminal 22, which is connected to the computer with a USB signal line and can obtain external power for the operation of the aforementioned peripheral devices. The USB interface 21 is coupled to a first USB interface signal IC23 with a line, such as an IC with a model nu...

Abstract

The invention is a computer expansion device with USB interface, including: a casing with a holding space; a circuit board arranged in the casing and having a USB interface and a power supply input end, where the USB interface is coupled with a first USB interface signal IC by lines, the IC is coupled with three first connection ends by lines and coupled with a second USB interface signal IC by lines, the IC is coupled with four second connection ends by another lines, the three first connection ends and a second connection end connect with the peripheral device that has USB interface conversion function, thus making them mutually transmit signals by the USB interface, and another three second connection ends are coupled to a USB interface socket.

Description

technical field [0001] The present invention is a computer expansion device with a universal serial bus (USB) interface, especially an expansion device that couples a computer peripheral device to a USB interface signal input / output to meet the expansion requirements of a mobile computer . Background technique [0002] According to the trend of computer development, the design has been towards miniaturization, such as the notebook computer in the portable computer, which is an obvious example. In order to consider the completeness of computer functions, its CD drive, hard disk drive, floppy disk drive and battery are Indispensable peripheral devices, according to the actual computer operation, most users install the operating system and application program in the hard disk, which can be adapted to the actual use, and the occasions where the notebook computer is used are mostly in the office or at home. Therefore, in order to break through the long-term hardware structure of...
