Description
Technical field
The utility model relates to hub field, specifically a kind of data sharing hub.
Background technology
The English of hub is called " Hub "." Hub " is that " meaning of " center ", the major function of hub carries out regeneration shaping to the received signal to amplify, and to expand the transmission range of network, all nodes concentrated on the node centered by it simultaneously.It works in OSI (Open System Interconnection reference model) reference model ground floor, i.e. " physical layer ".Hub is the same with the transmission medium such as network interface card, netting twine, belongs to the infrastructure device in local area network (LAN), adopts CSMA/CD (a kind of detection protocol) media access control mechanism.The each interface of hub simply receives and dispatches bit, receives 1 and just forwards 1, receives 0 and just forwards 0, do not carry out collision detection.
Hub (hub) belongs to pure hardware net underlying device, does not substantially have " intelligent memory " ability and " study " ability of being similar to switch.It does not possess the mac address table that switch has yet, so be all not targetedly when it sends data, but adopts broadcast mode to send.That is, when it will send data to certain node, not directly data are sent to destination node, but Packet Generation to all nodes be connected with hub, as shown in the figure, simple and clear.
HUB is the transponder of a multiport, and when centered by HUB during equipment, in network, certain circuit creates fault, does not affect the work of other circuit.So HUB is widely used in a local network.It is used in star-like with tree-network topology structure most of the time, and be connected with each main frame (also having bnc interface) with RJ45 interface, HUB has many types according to different sayings.
At present all there is corresponding shortcoming in hub on the market, cannot multi-platform transfer of data, cannot shared computer peripheral hardware, cannot support many mouthfuls of USB device simultaneously, cannot meet present rapid data transmission requirement.
Utility model content
The purpose of this utility model is to provide a kind of data sharing 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 data sharing hub, comprise bottom, pcb board, cover and PC cosmetic sheet, described bottom is provided with fixture; Described pcb board is provided with the holddown groove matched with fixture, described pcb board is by fixture and the clamping of holddown groove phase, described pcb board is provided with USB interface and signal input interface, and described bottom is provided with the USB interface preformed hole and signal input interface preformed hole that match with USB interface and signal input interface; Described pcb board connects circumscribed USB line, and described bottom is provided with the circumscribed USB line preformed hole matched with circumscribed USB line, is provided with HUB IC and OTI IC in described pcb board; Described cover is screwed connection bottom, and the both sides of described cover are provided with draw-in groove; The both sides of described PC cosmetic sheet are provided with the grab matched with draw-in groove, and described circumscribed USB line connects HUB IC, and signal input interface connects HUB IC by OTI IC, and described HUB IC exports connection USB interface respectively.
As further program of the utility model: described cover is provided with USB interface preformed hole.
As the utility model further scheme: described PC cosmetic sheet is by draw-in groove, grab and double faced adhesive tape and the clamping of cover phase.
Compared with prior art, the beneficial effects of the utility model are: the utility model compact conformation is simple, appearance looks elegant, solves multi-platform data transmission problems, can realize shared computer peripheral equipment simultaneously, save no small spending, support many mouthfuls of USB device simultaneously, support USB3.0 transfer of data, therefore transmission speed very fast, and self-contained data line, therefore use also very convenient.
Accompanying drawing explanation
Fig. 1 is the structural blast figure of a kind of data sharing hub of the utility model.
Fig. 2 is the structured flowchart of pcb board in a kind of data sharing hub of the utility model.
In figure: 1-bottom, 2-PCB plate, 3-cover, 4-PC cosmetic sheet, 5-circumscribed USB line, 6-circumscribed USB line preformed hole, 7-USB interface, 8-signal input interface, 9-USB interface preformed hole, 10-draw-in groove, 11-grab, 12-signal input interface preformed hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of data sharing hub, comprises bottom 1, pcb board 2, cover 3 and PC cosmetic sheet 4, and described bottom 1 is provided with fixture 12; Described pcb board 2 is provided with the holddown groove 13 matched with fixture 12, described pcb board 2 is by fixture 12 and the clamping of holddown groove 13 phase, described pcb board 2 is provided with USB interface 7 and signal input interface 8, and described bottom 1 is provided with the USB interface preformed hole 9 and signal input interface preformed hole 12 that match with USB interface 7 and signal input interface 8;
Described pcb board 2 connects circumscribed USB line 5, and described bottom 1 is provided with the circumscribed USB line preformed hole 6 matched with circumscribed USB line 5, is provided with HUB IC and OTI IC in described pcb board 2;
