1, during the power-off of hub place, the packet that server is transmitted to each computer by hub simultaneously will damage and disappear, so power supply kind is single, transfer of data continuity is poor.
2, because packet is sent to each computer by hub by server simultaneously, so computer carries out average sharing to the network bandwidth, network traffic congestion phenomenon may be caused, reduce network execution efficiency.
Utility model content
Main purpose of the present utility model is to solve problems of the prior art, provides the hub that a kind of transfer of data continuity is comparatively strong and network execution efficiency is higher.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of hub, comprise casing, uplink port, downlink port, regeneration shaping amplifying device, indicator light, display screen, charge power supply, diverter switch, wiring duct, groove door, power line and sucker, described casing top is provided with uplink port, described casing internal is provided with regeneration shaping amplifying device, described casing underside of forward is provided with downlink port, indicator light and display screen is separately installed with on the right side of described casing front portion, described casing front left is provided with charge power supply and diverter switch, described casing left part is fixed with wiring duct, described wiring duct left part slides up and down and is connected with groove door, described power line one end connects charge power supply, the other end is successively through casing and wiring duct, described casing bottom is provided with sucker.
Further, described casing top is also provided with radiating ribs.
Further, described uplink port and downlink port are RJ45 network interface.
Further, described diverter switch is double power supply automatic switching switch.
Further, described wiring duct inner right side is fixed with spill draw-in groove.
The beneficial effects of the utility model are:
1, diverter switch of the present utility model can be switched outside 220V alternating current and to be powered by power line and charge power supply is powered two states, and power supply kind is more, ensure that server is to each computer transmission data continuity; The regeneration shaping amplifying device of casing internal can carry out regeneration shaping and amplifies the pack signal that sends of server, to expand transmission range and the network bandwidth of network, avoids network traffic congestion phenomenon, improves network execution efficiency.
2, casing top of the present utility model is also provided with radiating ribs, and hub coordinates server running hours, will inevitably produce heat in casing, and radiating ribs can effective distribute heat, prevents casing internal device failure.
3, uplink port of the present utility model and downlink port are RJ45 network interface, and RJ45 network interface supports the adaptive network connection speed of 10M to 100M, RJ45 network interface and outer twisted pairs junction contacts sensitive, ensure that transfer rate.
4, diverter switch of the present utility model is double power supply automatic switching switch, when hub place power cut-off, double power supply automatic switching switch can switch to charge power supply power supply state from 220V alternating current by power line power supply state voluntarily, ensure that transfer of data continuity.
5, wiring duct inner right side of the present utility model is fixed with spill draw-in groove, and during non operating state, power line can be placed in spill draw-in groove in winding, ensure that the regularity of operational environment and power line is not fragile.
