Abstract
The invention discloses a USB (Universal Serial Bus) concentrator, and belongs to the field of computer-assisted equipment. The USB concentrator comprises a concentrator body, wherein at least two USB interfaces are arranged on one side of the concentrator body; a TF card slot and an SD card slot are arranged on the other side of the concentrator body; and the USB interfaces are connected with the concentrator body through telescopic lines. According to the USB concentrator with the structure, a storage card slot and the USB concentrator are combined, so that the usable range is enlarged; and the USB interfaces are pulled out to be used through the telescopic lines, so that the usable spacial range is enlarged.
Description
Technical field
The present invention relates to the computer-aided equipment field, particularly a kind of usb hub.
Background technology
In existing technology, usb hub mostly is the stationary housing that is provided with a plurality of USB interface, can only insert the USB joint, and some storage cards, for example: TF card or SD card must be furnished with corresponding card reader just can insert use, has in use caused much inconvenience, and because the USB joint is provided in a side of on housing, in use, because the problem of data wire length causes the plug of relevant device can't insert USB interface, cause the inconvenience of using.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of usb hub, to solve the above-mentioned multinomial defect that causes in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of usb hub, comprise the hub body, described hub body one side is provided with at least 2 USB interface, opposite side is provided with TF draw-in groove and SD draw-in groove, the hub body is provided with usb interface slot, and described USB interface and usb interface slot removably connect.
Preferably, described USB interface is connected with the hub body by line stretcher.
Preferably, described line stretcher length is 20-30cm.
adopt the beneficial effect of above technical scheme to be: the usb hub of structure of the present invention is provided with TF draw-in groove and SD draw-in groove, can directly insert TF card and SD card, increased the usb hub scope of application, USB interface is connected with the hub body by line stretcher, during use, can as required USB interface be elongated, enlarged the spatial dimension that usb hub uses, line stretcher length is 20-30cm, during length 20-30cm, line stretcher performance the best, line stretcher length is too short, do not reach the effect of the spatial dimension that enlarges the usb hub use, line stretcher length is long, its performance does not reach requirement, cause unnecessary electric energy loss.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
[0009]Wherein, 1--hub, 2--USB interface, 3--TF draw-in groove, 4--SD draw-in groove, 5--line stretcher, 6--USB interface slot.
Embodiment
Below in conjunction with accompanying drawing, describe the preferred embodiment of the present invention in detail.
Fig. 1 has shown the embodiment of a kind of usb hub of the present invention, this usb hub, comprise hub 1 body, hub 1 body one side is provided with at least 2 USB interface 2, opposite side is provided with TF draw-in groove 3 and SD draw-in groove 4, and hub 1 body is provided with usb interface slot 6, and USB interface 2 removably connects with usb interface slot 6, USB interface 2 is connected with hub 1 body by line stretcher 5, and line stretcher 5 length are 20-30cm.
In the present embodiment, hub 1 body is provided with TF draw-in groove 3 and SD draw-in groove 4, can directly insert TF card and SD card, and USB interface 2 is connected with hub 1 body by line stretcher 5, when distance is inadequate, USB interface 2 is pulled out,
Adopt the beneficial effect of above technical scheme to be: the usb hub of structure of the present invention is combined the storage card card reading slot with usb hub, enlarged the scope of application, and USB interface is pulled out use by line stretcher, has enlarged the spatial dimension of using.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
