Abstract
The invention discloses a telescopic USB interface device. The device comprises a base plate, a USB functional circuit board and a USB interface circuit board are arranged on the base plate, the input end of the USB functional circuit board is connected with a data transmission line, the output end of the USB interface circuit board is connected with a USB interface, and the USB interface circuit board is connected with the USB functional circuit board through a movable unit. The device has the advantages that the structure is simple, the design is skillful, the existing telescopic USB interface structure is improved in layout and production process, therefore a USB cap is not needed any more, and usage and keeping by users are facilitated.
Description
Technical field
The present invention relates to USB device field, specifically, specially refers to a kind of telescopic USB interface device.
Background technology
USB, English Universal Serial BUS(USB (universal serial bus)) abbreviation, and its Chinese referred to as " USB (universal serial bus) ", it is an external bus standard, be used for being connected and communication of standard computer and external unit, the interfacing that is applied in the PC field, the plug and play of USB interface support equipment and warm connection function.
Application number is that 200820134207 patent application document discloses a kind of Wireless Telecom Equipment with telescopic general-purpose serial bus USB interface, comprising: main circuit board comprises the basic circuit of Wireless Telecom Equipment; Interface card is used for drawing of carrying USB interface and usb data signal wire.Described interface card can slide with respect to main circuit board, keeps and being connected of main circuit board by the mode that is flexible coupling in sliding process; When sliding into favorite places, USB interface is hidden in the described Wireless Telecom Equipment, and when sliding into the use location, USB interface protrudes from the outer rim of main circuit board.
But the topological design of this telescopic USB interface structure is complicated, and complex production process is not easy to use, and is not suitable for large-scale production.
Summary of the invention
The object of the present invention is to provide a kind of telescopic USB interface device, by traditional telescopic USB interface structure being carried out improvement on the layout and the improvement on the production technology, thereby overcome the deficiencies in the prior art, realized purpose of the present invention.
Technical matters solved by the invention can realize by the following technical solutions:
A kind of telescopic USB interface device, comprise substrate, USB functional circuit plate and usb circuit plate are installed on the described substrate, the input end connection data transmission line of USB functional circuit plate, the output terminal of usb circuit plate connects USB interface, and described usb circuit plate connects USB functional circuit plate by head.
In one embodiment of the invention, described substrate is flexible PCB, and head is coil tension spring, and the two ends of coil tension spring connect respectively USB functional circuit plate and usb circuit plate.
In one embodiment of the invention, described USB interface is the USB3.0 interface.
Beneficial effect of the present invention is: simple in structure, design ingeniously, by traditional telescopic USB interface structure being carried out improvement on the layout and the improvement on the production technology, no longer need the USB block, give the user using and keeping brings convenience.
Description of drawings
Fig. 1 is the structural representation of a kind of telescopic USB interface device of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, a kind of telescopic USB interface device of the present invention, comprise substrate, USB functional circuit plate 100 and usb circuit plate 200 are installed on the described substrate, the input end connection data transmission line of USB functional circuit plate, the output terminal of usb circuit plate connects USB interface, and described usb circuit plate connects USB functional circuit plate by head.
In one embodiment of the invention, this substrate is flexible PCB, and head is coil tension spring, and the two ends of coil tension spring connect respectively USB functional circuit plate and usb circuit plate.
It should be noted that USB interface is the USB3.0 interface, USB 3.0 can be under the memory rate that memory device limits transmission of large capacity file (such as the HD film).
For example, one is adopted the flash drive of USB 3.0 data of 1GB to be transferred to a main frame in 15 seconds, and USB 2.0 is needs 43 seconds then.
Be subject to the promotion of the ever-increasing resolution of consumer electronics device and memory property demand, hope connects by broadband internet can realize wider media application, therefore, the user needs faster transmission performance, downloads, stores to simplify and sharing for multimedia a large amount of contents.USB 3.0 has played vital effect aspect its required simple connection providing for the consumer.
When being used for consumer device, USB 3.0 will solve USB 2.0 None-identifieds without the problem of battery device.Main frame can slowly reduce electric currents by USB 3.0, thereby identifies these devices, the mobile phone that has broken down such as battery.
Based on above-mentioned, of the present invention simple in structure, design ingeniously, by traditional telescopic USB interface structure being carried out improvement on the layout and the improvement on the production technology, no longer need the USB block, give the user using and keeping brings convenience.
Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
