USB is (English: Universal Serial Bus, be called for short USB) be the serial ports bus-bar standard connecting external device (ED), USB20D uses extensively on computers, but also can be used on Set Top Box and game machine, supplement standard On-The-Go (OTG) and direct swap date between portable unit can be used for.
USB is an external bus standard, for connection and the communication of specification computer and external equipment.USB interface plug and play and warm connection function.USB interface can connect 127 kinds of peripheral hardwares, as mouse and keyboard etc.USB is after being combined by Deng Duo company of Intel and released in 1996 the end of the year 1994, successfully substitutes serial ports and parallel port, and what become current computer and a large amount of smart machine must connect mouth.USB version experienced by development for many years, has developed into 3.0 versions by now.For most of engineer, exploitation USB2.0 interface product major obstacle is: in the face of complicated USB2.0 agreement, oneself write the driver of USB device, be familiar with the programming of single-chip microcomputer.This not only requires suitable VC programming experience, can also write hardware (firmware) program of USB interface, user is when using external equipment, do not need the shutdown action such as start again, but when computer work, directly USB is plugged and just can use, but existing like product each USB interface break-make uncontrollable, selection can only be realized by plug and read whether to coil, manual plug affects product useful life, and existing product switch cannot bear the circulation of big current simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of ultrahigh speed Ethernet card hub, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of ultrahigh speed Ethernet card hub, comprise bottom, pcb board, cover and switch key, described bottom is provided with buckle and fixture; Described pcb board is provided with the holddown groove matched with fixture, and bottom and pcb board are by fixture and the clamping of holddown groove phase; Described bottom is by buckle and the clamping of cover phase, and described cover is provided with switch preformed hole, indicator light preformed hole, USB interface preformed hole, network input port preformed hole and network delivery outlet preformed hole, and described switch key is connected on switch preformed hole; Described pcb board is provided with switch, USB interface, network input port and network delivery outlet, the upper Founder of described switch is to switch button, by switch key, switch is opened or Closed control, position corresponding indicator light preformed hole, USB interface preformed hole, network input port preformed hole and the network delivery outlet preformed hole respectively of described indicator light, USB interface, network input port and network delivery outlet, described switch is self-locking mechanical switch; Described USB interface series-connected switches, is connected in parallel master chip between multiple USB interface and power supply exports, and described network input port is by master chip and network chip series network delivery outlet.
As further program of the utility model: described pcb board is provided with indicator light.
As the utility model further scheme: described USB interface is connected in series indicator light.
Compared with prior art, the beneficial effects of the utility model are: the utility model passes through the combination of self-locking mechanical switch and electronic circuit, avoid the mistake that soft-touch type mechanical switch and electronic circuit combine and produce to operate, pass through composite type simultaneously, avoid the puzzlement that simple mechanical switch can not bear big current, each port special switch controls, unrestricted choice is facilitated to use, reduce energy consumption, it also avoid because frequent plug causes interface to damage simultaneously, the utility model overall compact, handsome in appearance, therefore have market prospects.
